Description

  The present invention relates to a tank-equipped vehicle that can exchange a tank and is useful for improving the operation rate of the vehicle, and a mount for the vehicle.

  Tank-equipped vehicles represented by tank trucks are widely used to transport liquids or liquefied components such as chemicals and fuels, and have a structure in which a subframe and a tank mounted on the vehicle chassis are integrated. Vehicles are known.

  In Japanese Patent Application Laid-Open No. 2007-137452 (Patent Document 1), in a tank lorry in which a sub-frame formed integrally with a tank is detachably connected to a chassis, liquid in the tank is placed between the tank and the chassis. It is described that a piping structure for discharging is provided. This piping structure has a concentration pipe connected to a plurality of bottom valves formed in the longitudinal direction of the tank, a first pipe extending in the width direction, and a branch opening from the first pipe to the rear opening end. A second valve inclined downward and a head valve for communicating a predetermined port among the plurality of ports, and the liquid in the tank is supplied to the end side of the first pipe and the second pipe. It is described that it can be discharged from the rear end of the pump, and that residual liquid is unlikely to be generated in the pump during gravity discharge. This document also describes a pump that can be driven using PTO (Power Take-Off).

  However, in this tank lorry, since the tank and the subframe are integrally formed, even if the subframe is fixed to the chassis, only the tank cannot be replaced. Therefore, it is necessary to wash the tank and the pipe when the type of the contents in the tank is different. In addition, even when the contents are the same, when the liquid component is transported in a tank having a different capacity, it is necessary to replace the subframe and the piping structure together with the tank. For this reason, the operating rate of the tank truck cannot be improved. Furthermore, it is not practical to replace the subframe and the piping structure every time the tank is replaced. Furthermore, if the piping structure is damaged, it is necessary to remove the subframe together with the tank from the chassis, lift it upward, and repair the piping from below. Therefore, the repair work is extremely complicated, and the repair efficiency is greatly reduced.

  A tank lorry that can detachably mount a tank has also been proposed. For example, in Japanese Patent Application Laid-Open No. 2004-106746 (Patent Document 2), the tank is supported by a support body configured by a substantially bowl-shaped container frame surrounding the tank, and the container frame is detachably attached to a loading platform of a vehicle body. The tanker truck mounted on is described. In this document, a discharge part of the fluid in the tank is provided at the front end of the tank, the pump device is equipped in the vicinity of the discharge part (under the loading platform), and the fluid outlet of the pump device is connected to the piping under the loading platform. It is also described that it is provided on the left and right sides of the vehicle body using

  However, in the tank lorry described in Patent Document 2, piping cannot be provided between the tank and the loading platform, and a piping structure including a pump device needs to be disposed under the loading platform. Therefore, not only the workability of the pump device and the piping is lowered, but also the piping and the like may be damaged during traveling. Further, if the piping structure is damaged, it is necessary to repair the piping from below in the lower space of the vehicle, so that the repairing work is extremely complicated and the repairing efficiency is greatly reduced. Furthermore, since it is necessary to position and mount the tank in the container frame, a container frame corresponding to the capacity and shape of the tank is required, and the tank cannot be replaced easily and efficiently. Further, since the fluid discharge portion in the tank is located at the front end portion of the tank, the stop position and stop direction of the vehicle are restricted, and the fluid injection and discharge work efficiency is greatly reduced. In addition, since a plate-shaped cargo bed is formed on the chassis, the weight increases and it is difficult to reduce the weight, and the offset position where the tank is mounted is located at the rear of the vehicle. It can only be applied to vehicles with two rear axles.

Japanese Unexamined Patent Publication No. 2007-137452 (Claims, [0035] [0043] [0048], FIG. 2) JP 2004-106746 A (claims, [0025] [0026], FIG. 1 and FIG. 6)

  Accordingly, it is an object of the present invention to provide a gantry that can be easily replaced with a tank and that is useful for improving the operating rate of the vehicle, and a tank-equipped vehicle equipped with the gantry.

  Another object of the present invention is to provide a pedestal having a high degree of freedom of piping and capable of arranging a pump between a chassis and a tank, and a tank-equipped vehicle equipped with the pedestal.

  Still another object of the present invention is to restrict the flow of tank fluid (tank at any part of the vehicle, for example, both sides and / or the rear end of the tank, without being restricted by the stop position and stop direction of the vehicle. It is an object of the present invention to provide a gantry capable of injecting fluid into the inside or discharging (or extracting) fluid from a tank, and a tank-equipped vehicle equipped with the gantry.

  Another object of the present invention is to reduce the residual liquid in the pipe, and to replace the tank and wash only the pipe, it is possible to cope with changes in different types of tank contents, and a tank equipped with this mount To provide a vehicle.

  Still another object of the present invention is to provide a gantry that can be reduced in weight while maintaining high strength and that can easily repair the piping structure, and a tank-equipped vehicle equipped with the gantry.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventor smoothly replaces only the tank when a predetermined form (for example, a cross-girder) is detachably disposed between the vehicle chassis and the tank. The present invention has been completed by finding that the operating rate of the vehicle can be greatly improved, and that the degree of freedom of piping can be greatly improved by piping using the height space of the gantry.

  That is, the gantry of the present invention is interposed between the chassis and the tank of the vehicle; a plurality of beam members that can be arranged at predetermined intervals in the width direction along the longitudinal direction of the chassis; An attachment member (a plurality of attachment members) attached to both sides (at least both sides) of these beam members; the tank disposed on the beam member and / or the attachment member (or arranged in a transverse form), and the tank And a pipe connectable to the external unit, and the beam member and the attachment member are detachable from the chassis and the tank, respectively. In such a gantry, since it is detachable with respect to the chassis of the vehicle and the tank is also detachable, the tank can be replaced and the operating rate of the vehicle can be improved. In addition, piping can be performed using the height space of the gantry, the degree of freedom of piping can be greatly improved, and a pump can be disposed between the chassis and the tank.

  A plurality of construction members may be attached between the plurality of beam members at a predetermined interval in the longitudinal direction. Further, the attachment member and the beam member may be connected by a reinforcing member having a brace shape. With such a construction member and / or a reinforcement member, it is possible to effectively reinforce the gantry while reducing the weight.

  The tank may be attached to a container frame to form a container tank. In such a container tank, the both ends of the mounting member and the container frame may be connectable, and the beam member and the chassis located outside in the width direction may be connectable. Further, the tank may be divided into a plurality of chambers, or may be a one-room tank.

  The piping may be attached (for example, fixed so as to be exchangeable) at least across the mounting member (for example, fixed in a replaceable manner), and the piping penetrates, for example, the lower part or the upper part except the upper wall or the lower wall of the mounting member. The pipe may be attached to the attachment member (for example, fixed in a replaceable manner) in a form inserted into a notch formed in the lower part or the upper part of the attachment member.

  In addition, piping is normally connected with this connection part via the connection part which can be connected with the connection port of the said tank, and a flow-path opening / closing valve with respect to the connection port of an external unit (external unit). A connecting portion that can be connected to each other, and fluid can flow between the tank and a unit outside the system. For example, the pipe may include a main pipe having a connection portion with respect to the tank and a sub-pipe branching from the main pipe and having a connection portion with respect to the external unit.

  More specifically, the gantry includes two beam members that can be disposed at predetermined intervals in the width direction along the longitudinal direction of the chassis; and mounting members that are attached to both sides of these beam members; A storage cross section formed transversely to the beam member and / or the mounting member and accommodating at least a part of the pipe; and disposed in the storage cross section (for example, extending in a transverse direction of the storage cross section) A main pipe having a connection portion connectable to the connection port of the tank; and arranged in a receiving cross section of the beam member and / or the mounting member. For example, it may be provided or extended in a form extending in the transverse direction of the housing crossing portion) and a sub-pipe having a connection portion connectable to the connection port of the external unit. For example, you may provide the two beam members which can be arrange | positioned at predetermined intervals in the width direction along the longitudinal direction of a chassis, and the attachment members (width direction extending to both sides of these beam members) For example, the attachment member may be attached extending in the width direction. The beam member and / or the attachment member, for example, the attachment member located at the rear of the vehicle, is formed so as to traverse (cross) the accommodating crossing portion in which at least a part (part or all) of the piping can be accommodated. The accommodating crossing part may be a notch part (for example, a semicircular notch part or an insertion part) formed in the lower part and / or upper part of the beam member and / or the mounting member. A through hole penetrating the beam member and / or the attachment member may be used. A main pipe may be disposed (for example, disposed extending in the transverse direction (or longitudinal direction)) in the accommodating cross section (notch section or the like), and the main pipe may be connected to a tank connection port (for example, In addition, a connecting portion that can be connected to a connecting port formed at the front or rear of the tank may be provided. With such a configuration, the main pipe may be inclined upward as it goes rearward.

  The beam member and the mounting member may be formed of a hollow square steel material (or pipe), and the erection member may be formed of a hollow square steel material (or a pipe) having a smaller thickness than the beam member and the mounting member, The erection member may be erected and connected to the upper wall or the lower wall of the beam member in a state where a space is formed in the lower or upper part.

  A sub pipe may branch from the main pipe in a predetermined direction (for example, at least one of a width direction and a rear direction; at least one width direction, for example, both width directions). Extends in a form (form in which the beam member and / or the mounting member is traversed (or penetrated)) disposed in the accommodating cross section formed in the beam member and / or the mounting member (for example, in at least one width direction) It may have a connection part to the external unit. The sub-pipe may be inclined downward (toward the connection portion or the width direction with respect to the external unit) in the direction of the connection portion with respect to the external unit (for example, the direction extending in the width direction). Furthermore, in the gantry, a pump (for example, a pump that can be operated by a drive system of a vehicle) may be connected to or positioned in the main pipe on the connection part side (rear side) of the tank with respect to the branch part of the sub pipe. In many cases, the chassis of a vehicle is usually inclined downward from the rear to the front.

  The piping structure may include a flow path switching valve that is attached to the main piping and switches the flow path, and a switching operation unit that operates the valve. The sub pipe branched from the main pipe may have an open / close unit including an open / close valve.

Further, the pipe is configured to have a first flow path through which a fluid can flow and a second flow path through which a medium for adjusting the temperature of the fluid in the flow path (for example, a heating medium for heating) can flow. And may have a multiple structure having a path. In such a pipe, the secondary pipe for supplying the medium to the second flow path is a form in which at least one member selected from the mounting member, the beam member, and the installation member is traversed or passed (penetrated). , It may be fixed to the member (for example, fixed in a replaceable manner).
Note that at least the beam member may be formed of a two-layered hollow steel material. Further, at least one frame forming member selected from the beam member, the mounting member, and the installation member (for example, the frame forming member formed of at least the beam member and the mounting member) may be coated with a paint.

  The present invention also includes a tank-equipped vehicle (tank lorry) in which the mount is interposed between a vehicle chassis and a tank. In this tank-equipped vehicle, the chassis and the beam member may be detachably connected (for example, detachable at a plurality of positions in the longitudinal direction of the beam member), and the tank and the attachment member may be detachable (for example, attached) It is also possible to connect to both sides of the member.

  In the present specification, the longitudinal direction means the forward direction and the backward direction of the vehicle, and the width direction means a direction intersecting (for example, orthogonal) with respect to the longitudinal direction. Means the forward direction and the reverse direction of the vehicle, respectively. The external unit includes a storage container (tank, drum container, etc.) capable of storing or preserving fluid in the tank of the vehicle, and may be fixed or transportable, and the fluid may be temporarily stored. It may be stored or stored.

  In addition, regarding the tank, the one-room specification is not limited to an aspect or form in which the tank has one room, but a plurality of rooms communicate or communicate through the communication hole even if the tank is partitioned by one or a plurality of partition walls. In the meaning which also includes the aspect or form (function or form which functions as one chamber).

  The term “base” is detachable with respect to the tank and the vehicle (chassis), and the fixed carrier and the fixed base for fixing the tank and the vehicle (chassis) and transporting the cargo in the tank. Or synonymous with joint base.

  In the present invention, since the gantry can be attached to and detached from the chassis and the tank, the tank can be easily replaced, and the operating rate of the vehicle can be improved. Moreover, the freedom degree of piping can be raised using the height space of a mount frame, and a pump can also be arrange | positioned between a chassis and a tank. Furthermore, since the degree of freedom of piping is large, piping can be made to any part of the vehicle, and the piping part (for example, both sides and / or the rear end of the tank) is not restricted by the stop position and stop direction of the vehicle. , It is possible to distribute the fluid in the tank (injecting fluid into the tank or discharging (or extracting) fluid from the tank). Furthermore, the residual liquid in piping can be reduced using the crossing accommodation part (for example, the lower notch part of an attachment member) of a beam member and / or an attachment member, and the inclination of sub piping. Also, if the tank contents are the same, it is possible to change tanks with different capacities by simply replacing the tank. Even if the tank contents are different, different types of tank replacement and pipe cleaning Can respond to changes in tank contents. Furthermore, by using a hollow square steel material and a reinforcing member, high strength can be maintained while reducing the weight. Furthermore, since the gantry can be attached to and detached from the chassis and the tank, the piping structure can be easily repaired. In particular, when the piping structure is attached to the gantry so as to be replaceable, repair and replacement are easy even if the piping structure is damaged.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  The tank-equipped vehicle shown in FIGS. 1 to 4 includes a gantry 6 between a vehicle chassis (or a frame serving as a skeleton of the vehicle) 1 and a tank (container-type tank) 2, and the gantry 6 includes the chassis 6. 1 and detachably connected to the tank. The vehicle chassis 1 is usually inclined downward as it goes from the rear to the front. Further, in the illustrated example, an example in which the connection port 2a is located behind the tank 2 is shown.

  As shown in FIG. 1, the tank 2 is not divided into a plurality of rooms, but is formed in a single room specification in which one tank 2 forms one room. Such a tank 2 is fixed to the container frame 3 to form a container type tank 2. The container frame 3 includes a rectangular frame frame 4 (corresponding to the ridge line of the rectangular parallelepiped) surrounding the tank 2, and upper and lower frames of the frame frame, side frames, and corner portions of the front and rear frames (in this example, upper and lower frames). The frame, four side portions of each side frame, and front and rear frames) are provided with reinforcing frames 5 fixed in a bracing manner. The container-type tank 2 conforms to the ISO standard and corresponds to the tank 2 having different capacities, so that the size and structure of the bottom side of the container frame 3 are the same, and various types of volumes (heights) are different. Tank 2 can be mounted.

  As shown in FIGS. 2 to 4, the gantry 6 includes two beam members 7 that can be disposed along the longitudinal direction of the chassis 1 at a predetermined interval in the width direction, and these beam members 7. And a mounting member 11 extending in the width direction to form a cross-shaped gantry body 13. In this example, both ends of the beam member 7 extend from the mounting member 11, and both sides of the mounting member 11 extend from the beam member 7. Furthermore, a plurality of erection members 14 are attached between the beam members 7 at a predetermined interval in the longitudinal direction in order to reinforce the gantry 6.

  More specifically, as shown in FIGS. 2 and 3, the attachment member 11 is formed of a hollow square steel material (steel material having a square cross section), and the upper walls of both ends of the attachment member 11 are A twist fitting 12a of a twist lock mechanism is attached to form a connection portion (twist lock connection portion) that can be detachably connected to the connection portion 12b of the container frame 3 by a twist lock method. Therefore, the gantry 6 can be detachably connected to the container frame 3 at both side portions (four corner portions) of the mounting member 11.

  The beam member 7 is formed of a hollow rectangular steel material (steel material having a square cross section) that is slightly lower in height than the first steel material of the mounting member 11, and the beam member 7 is a first steel material having a hollow square shape in cross section. In order to reinforce the first steel material 8, the second steel material 9 is welded to the top of the first steel material 8 and has a cross-sectional hollow square shape with a thickness (height) smaller than that of the first steel material 8. Thus, the mounting member 11 is welded together with the region including the joint portion between the first steel material 8 and the second steel material 9 and is integrally joined to the mounting member 11. Therefore, even if a large bending force acts in the width direction of the gantry 6 as the vehicle sways in the lateral direction, such a connection between the first steel material 8 and the second steel material 9 and an attachment member. 11 can resist the bending force. As shown in FIG. 1, the beam member 7 and the chassis 1 are provided with connecting portions (tightening portions that can be fastened with tightening bolts) 10a and 10b that are detachably connectable to each other at intervals in the longitudinal direction. Is formed. Therefore, it can be detachably connected to the chassis 1 at a plurality of positions in the longitudinal direction of the beam member 7.

  At the intersection (corner portion) between the two beam members 7 and the attachment member 11, a planar regular triangular first reinforcing member 15 is joined in a brace shape, and the two beam members 7 and the attachment member 11 are joined. A second reinforcing member 16 is joined to the extended portion in a brace shape to reinforce the gantry 6 or the gantry body 13. In this example, the height position of the first reinforcing member 15 on the inner wall side of the mounting member 11 is slightly lower than the first reinforcing member 15 on the outer wall side of the mounting member 11.

  Further, the installation member 14 installed between the two beam members 7 is formed of a hollow rectangular steel material (steel material having a square cross section) having a smaller thickness (height) than the beam member 7 and the mounting member 11. The beam member 7 is constructed and connected (welded) to the upper wall of the inner wall of the beam member 7, and is integrated with the beam member 7. In addition, a third reinforcing member having a right triangle shape such as a side regular triangle shape is formed at a lower intersection (between the lower inner wall of the beam member 7 and the lower wall of the installation member 14) between the beam member 7 and the installation member 14. An arch-shaped reinforcing member 17 is joined to form a space (for example, a piping space) below the erection member 14 in the gantry body 13.

  In the example shown in the figure, a beam member 7 is attached with a step from the mounting member 11 to the lower part of the gantry 6, and a second reinforcing member 16 is attached with a step from the beam member 7 to the lower part. The first reinforcing member 15 is attached at the same height as the member 16 or with a step at the bottom. For example, the first reinforcing member 15 (15 a) is attached at the same height position as the second reinforcing member 16 at the corner portion inside the attachment member 11, and the first reinforcement member 15 (15 a) is attached at the corner portion outside the attachment member 11. The reinforcing member 15 (15b) is attached at a position slightly lower than the second reinforcing member 16. In addition, closing plates (not shown) are joined to the opening portions at both ends of the attachment member 11 and the beam member 7, respectively.

  A piping structure having primary piping (main piping 21 and sub piping 23) and secondary piping 35 is formed in the lower space (intraframe space) of the gantry 6. In this example, a semicircular cutout portion 11a as a housing crossing portion is formed at the lower portion of the mounting member 11 located behind the vehicle (right side in FIG. 2, left side in FIG. 3). In 11a, a main pipe 21 provided with a connection portion 22 for the connection port 2a of the tank 2 is arranged extending in the longitudinal direction. When the main pipe 21 is disposed in the notch portion 11a of the rear mounting member 11, the rear of the main pipe 21 can be positioned (lifted) upward, and the main pipe 21 is moved upward as going backward. Can tilt. Therefore, coupled with the fact that the chassis 1 is inclined, the main pipe 21 can be further inclined (inclined further downward from the rear to the front). That is, the inclination angle of the main pipe 21 can be increased, and the liquid can flow in the forward direction of the main pipe 21.

  From the front portion of the main pipe 21, the sub pipes 23 are branched in a T-shape in both width directions (both width directions) via pipe joints. The first sub-pipe 24 and the second sub-pipe 26) extend in a form of being inserted (through the beam member 7) into a through hole formed in the beam member 7 as an accommodating transverse portion, and the sub-pipe 23 (24, 26). The extending end portion includes connecting portions (connecting portions having opening / closing valves, opening / closing valve units) 25 and 27 to the connection ports of the external unit. These sub-pipes 23 (24, 26) have short lengths to the connection portions 25, 27 with respect to the external unit, and are inclined downward in the lateral direction of the width direction. , 27 is located at the lowest height of the primary piping structure. For this reason, the liquid is caused to flow in the direction of the side of the sub pipe 23 to prevent the liquid from remaining in the pipe.

  Further, an opening / closing unit (connection portion) 30 having an opening / closing valve is attached to the rear portion of the main pipe 21, and the main between the opening / closing unit (connection portion) 30 and the connection portion 22 with respect to the opening of the tank 2. A third sub-pipe 28 branches and extends from the pipe 21. The third sub-pipe 28 can be connected to a connection port of an external unit, and is connected to an open / close valve (open / close). A valve unit 29 is attached.

  In this way, since the sub-pipe 23 is positioned on both sides (work space) and rear (overhang) of the vehicle, the vehicle 2 can be connected even if the connection port 2a of the tank 2 is positioned behind the vehicle. Regardless of the stop posture (stop position, stop direction) of the vehicle, the connection portion of the sub-pipe 23 (24, 26, 28) located on both sides and the rear portion of the vehicle is not restricted to one place on the rear side of the vehicle. (Connection parts of three sub-pipes) 25, 27, 29 can be used to circulate the liquid between the tank 2 and the external unit, and the liquid transfer work efficiency can be improved.

  Further, the main piping 21 on the rear side (the connecting portion side with the tank 2) of the branching portion of the sub piping 23 can be operated by a driving system (engine) of the vehicle via a driving transmission means (driving line) 31. A pump 32 (gear pump operable by a power take-off (PTO) system) 32 is connected. That is, a pump 32 is also installed in the lower space of the gantry 6 to form a compact structure. Unlike the conventional structure in which the pump is disposed behind the chassis 1, the pump 32 is disposed at a substantially central portion in the longitudinal direction of the chassis 1. Therefore, the pump 32 can be driven using the short drive transmission means (drive line) 31, and it is not necessary to drive the pump by arranging a hydraulic device (such as a hydraulic cylinder).

  As shown in FIG. 4, the main pipe 21 includes an angle or bracket 71 installed between the beam member 7 and / or the beam member 7, and the main pipe 21 using the angle or bracket. It is piped so as to be exchangeable or detachable using a temporary fixing fixing means (in this example, a U bolt 72) for temporarily fixing and fixing. The first and second sub-pipes 24 and 26 are also piped so as to be exchanged or detachable using a bracket 73 attached to the beam member 7 and a U bolt 72. Further, the pump 32 is fixed by using an angle or bracket 74 installed between the beam members 7 and a connecting metal fitting 75 for connecting the bracket and the pump 32. Note that as the temporary fixing means, it is possible to use support metal fittings (fixing metal fittings) such as saddle bands and hinge type bands.

  In such a pipe structure, since the sub pipe is located in front of the pump 32, it is possible to prevent the liquid from remaining (residual liquid) in the pipe (the main pipe 21 and the sub pipe) in front of the pump 32. Further, the tank 2 has a connection structure 22 that can be connected to the connection port 2a of the tank 2 and connection parts 25, 27, and 29 that can be connected to connection ports of units outside the system. The liquid can be circulated between the unit and the outside unit.

  In order to circulate the liquid through the main pipe 21 and the sub pipe 23, the pipe structure includes a flow path switching valve and a switching operation handle (operation unit). That is, in connection with or in conjunction with the operation of the pump 32, at least the fluid in the main pipe 21 is discharged or sucked (the fluid in the main pipe 21 flows out to the sub pipe 23 or flows out to the rear side of the main pipe 21). In the example, in order to further open the flow path of the main pipe 21, the flow path of the main pipe 21 and the sub pipe (the first sub pipe 24 or the second sub pipe 26) are selectively selected in the pump. For opening / closing (communicating or blocking) the valve (flow path switching valve, head valve or ball valve, not shown) and an operation unit for operating opening / closing or switching of the valve (switching operation handle or head valve operation) Handle) 33. The valve opening / closing operation portion (switching operation handle) 33 penetrates the beam member 7 (inserts through a through hole formed as an accommodating crossing portion in the beam member 7), and the side portion of the vehicle (for example, the chassis 1). In the longitudinal direction of the central part). That is, since the gantry body 13 has a cross-girder shape, a space can be formed on both sides of the gantry 6, and the operation portion (switching operation handle) 33 is positioned in one side space of the both side spaces. . Therefore, the space can be used as an operation space (or work space), and the valve opening / closing operation part (switching operation handle) 33 can be operated smoothly. In addition, in the space on both sides, as an arrangement space for arranging the connecting portions 25 and 27 of the sub-pipe 23 and various mounts (for example, a fire extinguisher 34a, a tool box 34b, a grounding conductor 34c, etc.). Can also be used. In this example, the valve (switching valve) is pulled out of the tank 2 by the operation of the pump 32 by the switching operation of the opening / closing operation unit (switching operation handle) 33 (according to the discharge of the fluid from the main pipe 21). , Transfer or discharge of liquid from the tank 2 to the external unit), injection of liquid into the tank 2 (transfer or injection of liquid from the external unit to the tank 2 accompanying the suction of the fluid in the main pipe 21), or by its own weight It is possible to transfer the liquid (flow or discharge of the liquid from the tank 2 to the external unit accompanying the opening of the flow path of the main pipe 21).

  The pipe is formed concentrically on a first flow path through which liquid can flow and an outer peripheral portion of the first flow path, and is a medium for adjusting the temperature of the liquid (for example, for heating or heating). Of the main pipe 21 and the sub-pipe 23, and the main pipe 21 and the sub-pipe 23 are connected to the main pipe 21 and the sub-pipe 23. A secondary pipe (a pipe through which a heating or heating medium can flow) 35 for heating or heating the fluid is connected. The secondary pipe 35 connected to the second flow path of the primary pipe (the main pipe 21 and the sub pipe 26) has at least the beam member 7 and / or the attachment member 11 (the attachment member 11, the beam member 7, and the installation member 14). At least one frame forming member selected from the above (for example, a form arranged in a housing crossing formed on the frame forming member, or a lower space of the frame forming member (for example, a construction member)) In the arrangement form, the member is fixed (for example, fixed so as to be replaceable). In this example, the secondary pipe 35 from the sub pipe 26 crosses or penetrates the beam member 7 and the erection member 14 (in a form inserted through a through hole as a housing crossing portion formed in the beam member and the erection member). The secondary pipe 35 extending from one side and extending from one side of the main pipe 21 crosses or penetrates the beam member 7 on the rear side of the vehicle (through-hole as an accommodating transverse part formed in the beam member). And extended to one side. The secondary pipe 35 is fixed to a bracket (or mounting base, stay) attached to the frame forming member so as to be exchangeable at a proper position by using a temporary fixing means such as a support metal (fixing metal). ing.

  In order to supply a heating or heating medium to the secondary pipe 35, the vehicle includes a tertiary pipe and a heating or heating unit. That is, the heating or heating unit includes a tank (or hot water tank) 38 (in this example, a tank 38 located on the front side of the front mounting member 11) for storing a liquid (for example, water), and the tank 38. A pump 36 (in this example, the pump 36 positioned between the first erection member 14 and the second erection member 14 from the front), and the pump 36. A heat exchanger 37 (heat exchange unit 37 positioned between the front mounting member 11 and the first installation member 14) for exchanging heat from the liquid transferred from the tank 38, The pump 36 and the heat exchanger 37 are each connected by a heating or heating pipe 39 as a tertiary pipe. The heat exchanger 37 is connected to a vehicle radiator (not shown) via a heat medium line 47. Further, the tank 38, the pump 36, and the heat exchanger 37 are each temporarily fixed by using an angle or a bracket similarly to the pump 32 and the like.

  The heating medium from the heat exchanger 37 is supplied to the secondary pipe 35 extending from the sub pipe 26 through the supply pipe 40 as a tertiary pipe, and the heating medium supplied to the secondary pipe 35 is supplied to the sub pipe 26 and the main pipe. While heating the fluid in the first flow path of the pipe 21, it passes through the second flow path of the sub-pipe 26 and the second flow path of the main pipe 21, and then from the main pipe 21 on the rear side of the vehicle. The medium that flows out to the secondary pipe 35 is supplied to the tank 38 through the recycle pipe 41 as a tertiary pipe.

  The secondary pipe 35 extending from the sub pipe 26 has a supply pipe 42 having a connection port 42a that can be connected to the supply port of the heating channel of the tank 2 in order to heat or heat the tank 2. The secondary pipe 35 connected and extending from the main pipe 21 is connected to an outflow pipe 43 having a connection port 43 a that can be connected to the outlet of the heating channel of the tank 2. The medium merges with the medium of the recycle pipe 41 as a tertiary pipe via the secondary pipe 35. It should be noted that the flow of switching between the secondary pipe 35 of the sub-pipe 26 and the supply pipe 40 as the tertiary pipe, the switching of the flow path between the secondary pipe 35 of the main pipe 21 and the recycle pipe 41 as the tertiary pipe, etc. The path can be switched by a valve (not shown).

  In the illustrated example, the heating medium can be introduced into the second flow path through the secondary pipe 35 in the form of steam or the like. That is, in this example, a heating medium (steam or the like) is supplied to the second flow path through the steam inlet 44 of the steam pipe connected to the secondary pipe 35 of the sub pipe 26, and the primary pipe (sub pipe 23). The heating medium flowing along the main pipe 21) is discharged or discharged from the discharge port 45 of the steam pipe branched from the secondary pipe 35 of the main pipe 21 on the rear side. The flow path between the secondary pipe 35 and the steam pipe can also be switched by a valve (not shown) as described above.

  Since such a gantry 6 can be attached to and detached from the container type tank 2 and the chassis 1, the tank (container type tank) 2 can be replaced. More specifically, in the tank 2 having only different liquid capacities, the tank 2 can be replaced with a different volume without washing the tank 2. Further, when transporting different types of liquids, it is only necessary to replace the container-type tank and clean only the piping, and coupled with the reduction of the residual liquid, the amount of waste liquid can be greatly reduced. Further, even when the tank 2 needs to be cleaned, the tank 2 is a single chamber specification, so that the cleaning is easy. Therefore, the operation rate of the vehicle can be greatly improved. In addition, since the tank 2 has a single chamber specification, an overflow accident due to liquid injection hardly occurs.

  Further, the height space of the gantry 6 can be used for piping, and the degree of freedom of piping can be greatly improved, and a pump 32 is also disposed between the chassis 1 and the tank 2 (for example, at the center in the longitudinal direction of the chassis 1). Installation). Moreover, the main pipe 21 can be lowered at a large inclination angle toward the front of the vehicle, and the sub pipe 23 having a short length can be lowered and inclined in the width direction. Therefore, the generation of residual liquid in the pipe can be suppressed as much as possible, and maintenance can be reduced. Furthermore, since the connection parts 25 and 27 of the subpipe 23 and the operation part 33 are located on both sides of the gantry 6, the liquid can be smoothly injected and discharged. Furthermore, even if the piping structure is damaged, the gantry 6 can be detached and the damaged piping can be replaced, so that the repairing operation can be performed very simply and efficiently. Moreover, since the mount frame 6 can be formed with a hollow frame forming member (hollow structure) and a reinforcing member, high strength can be maintained while reducing the weight.

  The gantry may be formed of at least a plurality of the beam members and at least a plurality of attachment members that can be attached to at least both longitudinal sides of these beam members. For example, the pedestal only needs to include at least two beam members that can be disposed at a predetermined interval in the width direction along the longitudinal direction of the chassis. A beam member may be provided. Further, the attachment member may be attached to the end portions (or both end portions) of the beam member (for example, may be attached extending in the width direction), or the intermediate portion ( Or it may be attached to both side portions (for example, it may be attached extending in the width direction). Furthermore, at least two attachment members attached to both ends or both sides of the beam member may be provided, and a plurality of three or more attachment members may be attached to the beam member at intervals in the longitudinal direction of the beam member. Also good. Furthermore, the attachment member only needs to extend in a direction intersecting the longitudinal direction of the beam member and be attached to the beam member. The attachment member is inclined with respect to the longitudinal direction of the beam member, and the width direction (the longitudinal direction of the beam member). For example, extending in the width direction of the beam member.

  In addition, the mounting member and the beam member may form a plane square frame, and in this plane square frame, the mounting member is orthogonal to the longitudinal direction of the beam member, obliquely (for example, parallel and in the same direction) In a different direction such as an octagonal shape), and a planar square frame formed by a plurality of adjacent planar polygonal frames (for example, a planar triangular frame and / or a rectangular frame). It may be formed, and the end portions of the attachment member and the beam member do not need to extend from the square frame. A preferred form may be a rectangular square frame (particularly, a cross-shaped square frame) corresponding to the chassis. In many cases, the end of the mounting member extends from the square frame.

  It is not always necessary to lay the erection member between the beam members. However, in order to not only reinforce the gantry but also fix the piping structure to be replaceable, at least one (for example, with a predetermined interval in the longitudinal direction) It is preferable to install a plurality of installation members. In addition, bracing reinforcing members (the first reinforcing member and the second reinforcing member (the bracing member) at the intersection of the beam member and the mounting member) are not necessarily required, but these members also reinforce the gantry. It is useful in. If necessary, each corner portion is not limited to a plurality of bracing reinforcing members (first and second reinforcing members), and a single reinforcing member is connected to the mounting member and the beam member in a bracing manner. Also good. Moreover, you may attach a reinforcement member to the corner part of a beam member and a construction member in the shape of a brace. The height position of the first reinforcing member at the intersection of the beam member and the mounting member (and / or the erection member) may be the same or different on the inner wall and the outer wall of the mounting member. The first reinforcing member on the outer wall side may be positioned above the first reinforcing member on the inner wall side.

  The beam member, the mounting member, and the erection member (frame forming member) are not limited to the hollow square steel material as long as the mechanical strength can be maintained, and various forms of materials can be used. Good. For example, the mounting member may be formed of two joined hollow steel materials, the beam member is not necessarily formed of two hollow steel materials, and the first and / or second steel materials may not be hollow. . The frame forming member preferably has a hollow structure for weight reduction. A frame forming member (at least a beam member or the like) formed of a two-tiered hollow steel material is lightweight and reinforced. In addition, various joint structures (such as joint structures such as notches, crossing jaws or crossing structures) may be used for the shaft assembly (joining) between the beam member and the mounting member (and also the installation member). Good.

  A step may be formed on the upper wall (upper end surface) of the beam member, the mounting member, and the installation member, and the upper wall (upper end surface) of the frame forming member may be formed substantially flush without forming a step. Also good. For example, the attachment member and the beam member (and also the erection member) may form a frame forming member (or a gantry) with the same height (for example, the upper end surface is substantially flush), and the reference member ( For example, the height position (upper end surface) of the beam member may be higher than the height position (upper end surface) of other members (for example, the mounting member and / or the erection member). The position is the same as the height position of the beam member or higher than the height position of the beam member, and the height position of the beam member is often the same as the height position of the construction member or higher than the height position of the construction member. .

  Further, the installation member is not limited to the upper part of the inner wall of the beam member (upper wall of the inner wall facing the beam member), but may be attached to the lower part of the inner wall of the beam member (lower wall of the opposing inner wall). You may attach to (the intermediate part of the opposing internal wall). The installation member may be attached between the beam members in a form that blocks the space extending in the longitudinal direction of the beam member (for example, an installation member having the same height or thickness as the beam member). You may attach between beam members with the form (for example, installation member which has communication parts, such as an installation member smaller than a beam member, a notch part, or a through-hole).

  Since the installation member forms a space in the lower part or upper part of the gantry body, it is preferable that the height (or thickness) is smaller than that of the beam member and the mounting member, and a third reinforcing member is joined to the installation member and the beam member. Although it is not necessary, the strength of the frame forming member can be greatly improved by joining the third reinforcing member. The third reinforcing member only needs to be able to reinforce the erection member and the beam member in a bracing manner, and is not limited to a right-angled triangular section, and can contact the inner wall of the intersection of the beam member and the erection member. In many cases, the hypotenuse has a cross-sectional shape having a side and a hypotenuse extending obliquely between the beam member and the erection member, and the hypotenuse is not limited to a linear slope, but is curved outward or inward. You may form with a curved surface. The third reinforcing member may be attached in an arch shape (downward arch shape) with the hypotenuse downward, for example, on the upper inner wall of the intersection, as in the above example, for example, on the lower inner wall of the intersection, It may be attached with the hypotenuse facing upward or in a reverse arch shape (upward arch shape), or in both an arch shape and a reverse arch shape. In the aspect in which the third reinforcing member is attached in the inverted arch shape, the erection member may be capable of mounting or receiving a pipe (primary pipe, secondary pipe, and / or tertiary pipe). If it exists, it may be fixed or temporarily fixed. It is preferable to form the erection member in the form of an arch (downward or upward arch) by joining the third reinforcing member. It should be noted that a bending force acts in the width direction of the gantry (frame forming member) as the vehicle swings in the width direction (lateral direction). In order to resist such bending force, it is advantageous to form an arched erection member using a reinforcing member.

  In the present invention, piping can be made in the gantry body using the height space of the gantry, and the degree of freedom of piping is high. The pipe is attached (for example, fixed to be exchangeable) to at least one member (for example, at least the beam member and / or the attachment member) selected from a beam member, an attachment member, and an installation member, and is connected to the connection port of the tank. Connectable to the connection port of the external unit (unit outside the system) via the connection part (main pipe connection part) that can be connected to this and the connection part via the flow path opening / closing valve (Sub-pipe connection). These connection portions may be connectable to the connection ports of the tank and the external unit directly or indirectly through a hose or the like. The connecting portion may function as a discharge portion for discharging or discharging the liquid in the tank or an injection portion for injecting the liquid into the tank by a switching valve in the switching operation valve. In addition, an opening / closing unit having an opening / closing valve is usually attached to each connection portion.

  The frame forming member (at least a member selected from a beam member, a mounting member, and an installation member, in particular, at least a beam member and / or a mounting member) includes at least piping (primary piping, secondary piping, and / or tertiary piping). An accommodating cross section capable of accommodating a part (a part or the whole) can be formed. This accommodating crossing part may be a cutout part, a through hole, or the like formed in the frame forming member, and the cutout part is provided at a lower part and / or an upper part of the frame forming member, and a pipe crosses the frame forming member. Can be formed, for example, a U-shape, a U-shape (semicircle), a V-shape, or the like.

  In addition, in the frame forming member (for example, the mounting member located at the rear of the vehicle) traversed by the pipe connected to the connection port of the tank, the notch part (lower or upper part) is used to position (pick up) the pipe upward. In many cases, a notch) or a through hole is formed, and a through hole or a lower notch is formed on the frame forming member traversed by the pipe connected to the connection port of the external unit in order to lower the pipe. There are many.

  The pipe is usually arranged extending in the longitudinal direction, and a main pipe having a connection portion connectable to a tank connection port (for example, a tank connection port formed at the front or rear of the vehicle), It is often equipped with a sub-pipe having a connection part that branches off from the main pipe and can be connected to the connection port of the external unit. The sub-pipe can be connected to the connection port of the external unit from the main pipe. In the form, it suffices to branch directly or indirectly in at least one of the width direction and the rear direction. Usually, at least one width direction (or both width directions) is branched in the rear direction. There are many cases. Further, as described above, the sub pipe may be branched from the main pipe on the connection port side of the tank. The sub pipe may extend in a direction intersecting with the main pipe and may extend in an oblique direction. However, in order to effectively use the lower space of the gantry body, the sub pipe is orthogonal to the main pipe. Often extends in the direction.

  In the above example, the opening / closing operation portion of the valve is located on one side of the vehicle, but in the present invention, since the degree of freedom of piping is large, the opening / closing operation portion is located at an appropriate position of the vehicle or the gantry. Can be positioned. FIG. 6 is a schematic plan view showing another example of the gantry of the present invention. In the following illustrated examples, common members or units will be described with the same reference numerals as those described above.

  In this example, a pump (gear pump) 52 is connected adjacent to the connection portion 22 of the main pipe 21 with respect to the connection port located at the rear of the tank 2, and the switching operation of the on-off valve (switching valve) of the pump 52 is performed. The opening / closing or switching operation portion (or operation handle) 53 is positioned behind the tank 2 (overhang portion behind the vehicle) without penetrating the beam member 7.

  Further, between the main pipe 21 connected to the connection port of the pump 52 and the branch portion where the first sub pipe 24 and the second sub pipe 26 branch in a T-shape (in this example, the main pipe 21 An opening / closing unit 60 having an opening / closing valve is connected to the rearmost part of the pipe 21 and outside the mounting member 11 of the gantry body 13, and the opening / closing unit 60 and the valve opening / closing or switching operation unit 53 are connected to each other. A short third sub-pipe 58 extends and branches from the main pipe 21 therebetween, and an opening / closing valve unit 59 is attached to a connection portion of the third sub-pipe 58.

  In such a piping structure, the connecting portion 59 of one sub-pipe 58 located in the rear (overhang portion) of the vehicle and the connecting portion 25 of the two sub-pipes 24 and 26 located in the operation space on both sides of the vehicle. , 27 (a total of three sub-piping connections), regardless of the stopping position of the vehicle, the opening / closing or switching operation unit 53 switches the flow path using an on-off valve. 27, 59 can be used to circulate liquid between the tank 2 and the external unit.

  The pump (gear pump) is also accommodated in the gantry body, the third sub-pipe is also extended from the gantry body, and the opening / closing valve switching or switching operation part (or operation handle) of the pump is provided. You may extend from a beam member.

  In the above example, the connecting portion of the sub piping with respect to the external unit is located in the central portion (central region) in the longitudinal direction of one side portion of the vehicle (or the gantry), but the degree of freedom of piping is high. By utilizing this, the connecting portion of the sub-pipe can be positioned at an appropriate position of the vehicle. FIG. 7 is a schematic plan view showing still another example of the gantry of the present invention.

  In this example, by utilizing the high degree of freedom of piping, unlike the piping structure shown in FIG. 2, the main piping 61 is curved or bent and extends in the longitudinal direction. The first sub-pipe 24 branches at the front branch portion of the main pipe 21 extending in the longitudinal direction without connecting the third sub-pipe 28, and the connection part 25 with the external unit is a vehicle (or a frame). 6 on one side, the second sub-pipe 66 is branched and curved (in this example, curved backward), and is located in the longitudinal center (central region). The connecting portion 67 is located on the other side of the vehicle (or the gantry) 6 on the rear side of the central portion (central region) in the longitudinal direction. In addition, the main piping 61 is provided with the connection part 62 with a tank similarly to the above.

  Even in such a pipe structure, the tank 2 is used on both sides of the vehicle (or the gantry) 6 by using the connecting portions 25 and 67 of the first sub pipe 24 and the second sub pipe 66 at different positions in the longitudinal direction. Liquid can be transferred between the unit and the external unit.

  Note that the sub-pipe only needs to branch from the main pipe in at least one width direction, and is not limited to the width direction, but in the direction of the connection port of the tank (for example, front or rear) (in the above example, It may extend backward). FIG. 8 is a schematic plan view showing another example of the gantry of the present invention.

  In this example, the sub pipe 23 extending from the main pipe 21 branches from the front portion of the main pipe 21 in both width directions (both width directions) in a T shape and extends through the beam member 7. The sub-pipe 24 and the second sub-pipe 26 and the second sub-pipe 26 located on the side of the gantry body 13 extend in the rearward direction of the vehicle and extend in the gantry body 13 in parallel with the main pipe 21. The third sub-pipe 88 extends from the second sub-pipe 26 in the rearward direction of the vehicle, curves or bends, passes through the beam member 7, and the gantry body. 13 extends in the direction of the rear portion of the main pipe 21. Similarly to the above, the third sub-pipe 88 is also provided with a connecting portion (an opening / closing unit having an opening / closing valve) 89.

  Further, in order to avoid the generation of residual liquid in the pipe, the main pipe 21 passes through the upper part of the side wall of the mounting member 11 on the rear side, and the third sub-pipe 88 is the side wall of the mounting member 11 on the rear side. The rear portion of the main pipe 21 (the main pipe 21 that penetrates the attachment member 11 on the rear side) is located at a higher position than the third sub-pipe 88. The connecting portions 25 and 27 of the first sub-pipe 24 and the second sub-pipe 26 and the connecting portion 89 of the third sub-pipe 88 are through-holes of the beam member 7, the mounting member 11, and the installation member 14. By adjusting the height position and the depth (or height) of the notch, it can be positioned at substantially the same high position. Further, the height position at which the main pipe 21 crosses (penetrates) the attachment member 11 on the side of the connection portion with respect to the tank may be equal to or lower than the height position of the connection portion between the pump 32 and the main pipe 21. It may be slightly higher.

  In such a pipe, the connecting portions 25, 27, and 89 of the first sub-pipe 24, the second sub-pipe 26, and the third sub-pipe 88 are used, and both sides and the rear of the vehicle (or the gantry) 6 are used. The liquid can be transferred between the tank 2 and the external unit.

  In addition, the connection part of main piping with respect to the connection port of a tank can be located in the site | part of the vehicle (or mount) corresponding to the position (for example, front or back) of the connection port of a tank. In addition, the connecting portion of the sub-pipe with respect to the external unit has a high degree of freedom of piping, so it can be positioned at an appropriate position in the vehicle, and at least one side (for example, both sides) of the vehicle (or the base), the rear portion / It can also be located in the front part. In addition, the connecting portion of the sub piping may be positioned at the front portion, the middle portion, and the rear portion in the longitudinal direction on the side portion of the vehicle (or the gantry). In many cases, the connecting portion of the sub-pipe is located at least on both sides of the vehicle (or the gantry), and when located on both sides and the rear of the vehicle (or the gantry), as described above, regardless of the stopping posture of the vehicle. The liquid can be circulated between the tank and the external unit, and the liquid transfer work efficiency can be improved.

  The piping preferably forms a piping structure in a form that traverses or passes at least (or across) a mounting member (for example, a lower part of the mounting member). Such a crossing or passing form is formed in a form penetrating through a through hole of the frame forming member (beam member, mounting member and installation member), and in an upper part and / or a lower part (especially a lower part) of the frame forming member. It may be in the form of being inserted or disposed in a notch (a U-shaped cross section, semicircular notch, etc.), and the inner wall of the frame forming member (or the lower wall and / or the inner wall of the installation member) It is also possible to use a form in which the bracket is attached through a bracket so as to be replaceable.

  Since the chassis of a vehicle is usually inclined downward and forward from the rear, the main pipe does not necessarily have to be inclined, but a pipe crossing or passing part of the pipe (for example, the main pipe) with respect to the mounting member By adjusting the inclination of the pipe, the inclination of the pipe can be adjusted. Therefore, you may incline below toward the transfer direction (For example, the transfer direction from the connection port of the tank formed in the front or back to the connection port of an external unit). The inclination of the main pipe can be easily and accurately adjusted using the mounting member and / or the erection member. For example, depending on the inclination direction of the main pipe, a through hole is formed in the mounting member (at least one mounting member) located at the rear or front of the vehicle, or a notch (semi-circular notch) is formed in the lower part of the mounting member. Etc.), and the main piping may be disposed in the notch to extend in the longitudinal direction. Further, depending on the inclination direction of the main pipe, a through hole or a notch may be formed in the erection member located at the rear or front of the vehicle, and the main pipe may be disposed in the same manner as described above.

  The main pipe extends in the longitudinal direction at least in a through-hole or a notch formed in the lower part of the mounting member (for example, the rear mounting member when the tank connection port is located at the rear). There are many cases to do. Further, according to such an arrangement, the main pipe can be inclined in a predetermined direction (for example, inclined upward as it goes backward, or downward as it goes forward).

  The frame forming member (at least one member selected from a beam member, a mounting member and an installation member) is coated with a paint such as a rust preventive paint or a chemical resistant paint (such as a solvent resistant paint) to improve durability. May be. In particular, in order to prevent salt damage, it is advantageous to coat with a rust preventive paint. The paint may be an oily type or an aqueous type.

  The main pipe can be connected to a pump for flowing liquid between the tank and the external unit; for selectively switching (communication / blocking) the flow path between the main pipe and the sub pipe. The flow path switching valve (switching valve, on-off valve (switching valve)) may be disposed adjacent to the pump, but is usually integrated with the pump. The position of this pump is not particularly limited due to the high degree of freedom of piping, and can be placed at an appropriate position in the gantry body. The valve (open / close valve or switching valve) can be switched or the opening / closing operation part (head valve operation handle) can also flow. Depending on the arrangement position of the path switching valve, it can be arranged separately from the beam member (or away from the mount) or extended from a suitable position of the beam member. Either an intermediate part (central area) or a front part may be used. In the rectangular frame-like gantry body, similarly to the pump, a valve can be arranged in the central portion (or central region) in the longitudinal direction, and the switching or opening / closing operation shaft portion of this valve penetrates one beam member, In many cases, the valve opening / closing operation part is located in the central part (or central region) in the longitudinal direction, and the valve opening / closing operation part (head valve operation handle) of the pump (gear pump) is separated from the beam member, for example, a stand You may arrange | position in the outer side or rear part (for example, the overhang part or working part of the rear part of a vehicle) of a main body. The flow path switching valve is not limited to the head valve and the ball valve, and various valves such as a butterfly valve, a globe valve, and a gate valve can be used according to the flow path of the main piping and the sub piping and the flow direction of the fluid. . In many cases, an opening / closing valve for opening / closing a fluid flow path to / from a tank or an external unit is attached to the connecting portion of the main piping and the sub piping.

  In the present invention, since the opening / closing operation space (work space) of the pump can be formed on the side portion of the vehicle (or the gantry), the position of the pump is often the middle portion (central region) in the longitudinal direction of the gantry. When the pump is installed at such a position, the operating force from the engine can be transmitted to the pump through a short path. In addition, since the chassis is usually inclined downward toward the front, residual liquid in the pipe can be prevented by positioning the sub pipe in front of the pump.

  The pump can be provided in the main pipe and / or the sub pipe, and normally, in the main pipe, the tank is closer to the connection port of the tank than the branch section of the sub pipe (for example, the rear side of the branch section in the above example). It is often provided, and may be provided at an appropriate position between the branch portion of the sub pipe and the connection portion with respect to the connection port of the tank, for example, on the side close to the branch portion, or on the connection portion side with respect to the tank. Further, the height position of the connecting portion of the main pipe with respect to the pump is not particularly limited, and may be located at the lowest, middle position, and highest portion of the piping structure, but the height of the connecting portion with the pump The position may be the highest position, and may be the same as, lower than, or higher than the height position at which the main piping crosses (penetrates or inserts) the attachment member on the connection side with respect to the tank.

  The type of the pump is not particularly limited, but usually, the pump is a pump (gear pump) that can be operated by a drive system (engine) of the vehicle because the operating force is transmitted through a short path.

  The sub pipe extends in the width direction in a form crossing the beam member (a form in which the through hole of the beam member is penetrated or arranged in the notch hole), and the height position of the sub pipe penetrating the beam member is adjusted. Thus, the inclination angle of the sub pipe can be adjusted. The sub-pipe does not necessarily have to be inclined downward as it goes in the side direction in the width direction, and may be slightly inclined upward or extend in the horizontal direction. In a preferred embodiment, in order to reduce residual liquid, the sub pipe is arranged on the side in the width direction by forming a through pipe in the beam member at a position lower than the connection position of the sub pipe to the pump. It is inclined downward as it goes in the part direction. With such a piping structure, the connecting portion of the sub piping (the connecting portion with respect to the connection port of the external unit) may be located at the lowermost part of the piping structure.

  The piping structure does not have to be a concentric double pipe structure having the first flow path and the second flow path, but a pipe or a hose that forms a single flow path (for example, a flexible hose) ), And may have a concentric or non-concentric multiple tube structure having more flow paths.

  Secondary piping and / or tertiary piping are not necessarily required. Further, the secondary pipe and / or the tertiary pipe may use not only the heating medium but also a refrigerant or the like depending on the type of fluid. Such a refrigerant supply unit may also be disposed within the frame of the gantry body, similar to the heating medium supply unit (pump, heat exchanger, hot water tank, secondary pipe and / or tertiary pipe, etc.). In addition, the arrangement form of the heating medium or the refrigerant supply unit (pump, heat exchanger, tank, etc.) is not limited to the above form, and can be arranged in various forms, and some units are located outside the frame of the gantry body. May be. The secondary pipe and / or the tertiary pipe are arranged in a form that crosses or passes through the frame forming member (at least one member selected from the beam member, the mounting member, and the installation member) according to the piping structure, as described above. In many cases, the secondary pipe and / or the tertiary pipe are attached in a form penetrating the frame forming member or inserted into a notch portion of the frame forming member.

  Also, piping for supplying a heating medium or refrigerant to the tank flow path and piping for heating with a heating medium such as steam (for example, high temperature heating with a high temperature heating medium) are not necessarily required.

  The primary piping (main piping, sub piping), and the secondary piping and / or tertiary piping are crossed or passed through the frame forming member, and may be fixed to the frame forming member in a non-replaceable (or integrated) manner. However, in order to repair the piping structure, conventional temporary fixing means according to the piping configuration (for example, fixing members such as U-bolts, bolts / nuts, stoppers, etc .; engaging members such as hook members; support fittings) Etc.) may be fixed to the frame forming member in a replaceable manner, or may be fixed in a replaceable manner via a bracket (attachment portion) attached to the frame forming member. The bracket only needs to have an extending portion (attachment portion) extending inward of the gantry body, and the extending portion extending upward from the extending portion is fixed to a construction member or the like in an L-shaped cross section. May be.

  The tank may be a tank partitioned into a plurality of rooms (a tank having a storage space capable of storing a plurality of different types of liquid components). There are advantages. When tanks partitioned into a plurality of rooms are used, connecting portions (opening / closing units provided with opening / closing valves) to the connection ports of the rooms may be formed in the main piping at intervals in the longitudinal direction. .

  The type of the transported object (or the tank contents) transported in the tank is not particularly limited as long as it is a fluid (fluid), and includes gas (including liquefied gas), liquid, or liquid composition (including viscous material). Or the like.

  The tank is only required to be detachable or replaceable with respect to the gantry, and the tank and the gantry may be directly connected. Usually, however, the tank and the gantry are indirectly fixed using an intermediate member. Are often connected together. It is advantageous to use a container frame surrounding the tank as such an intermediate member. The form of the container frame usually has a frame frame that can surround the tank, and this frame frame is reinforced by a bracing reinforcement frame. The form of the frame of the container frame is not particularly limited, and may be a square columnar body, for example, a frame corresponding to a ridge line of a rectangular parallelepiped or a cube, depending on the form of the tank. In particular, in the ISO standard, the size and structure of the bottom side of the container frame are the same, and various tanks having different volumes (heights) can be mounted. Therefore, it is suitably applied to a tank (container type tank) mounted on such a container frame.

  The attachment / detachment mechanism between the beam member and the chassis can be fixed to each other, and is not particularly limited as long as it does not hinder the transportation of the tank. Various fixing devices used for the transportation of the tank, such as bolts / nuts and tightening bolts. Fasteners such as can be used. Note that the attachment / detachment mechanism reinforcing frame between the beam member (for example, a beam member on the outer side in the width direction in the case of a plurality of beam members) and the chassis is often attached at intervals in the longitudinal direction of the beam member and the chassis.

  The attachment / detachment mechanism between the mounting member and the tank (or container type tank) is also not particularly limited as long as both can be stably fixed and there is no problem in transporting the tank. A mechanism such as a twist lock mechanism (rotation lock mechanism) can be used. In the twist lock mechanism, the attachment member and the container frame (tank) may be coupled (locked) and released (unlocked) semi-automatically or automatically (auto twist lock mechanism). The attachment / detachment mechanism between the attachment member and the tank (or container-type tank) can be formed at an appropriate position of the attachment member, but usually, there are four corner portions (four corners), for example, both side portions (for example, both end portions) of the attachment member. It is often formed at the corner of the container frame (tank), and a protruding twist fitting is often attached to the mounting member.

  In addition, as described above, the operation space (work space) and the arrangement space can be formed on the side portion of the vehicle by the frame main body such as the cross beam. ), A valve (switching valve) opening / closing operation handle or the like can be positioned, and various bodywork such as a fire extinguisher, tools, a ladder, and the like can be arranged.

  Further, the tank-equipped vehicle may be provided with a nitrogen gas sealing unit for injecting nitrogen gas or the like into the tank according to the type of contents in the tank.

  Note that the vehicle of the present invention does not necessarily require a pipe drain (water pipe), so that it is possible to prevent an accident of forgetting to close the drain valve.

  The tank-equipped vehicle of the present invention has a replaceable tank and can improve the operation rate. Therefore, various fluids such as gas components such as liquefied gas, light oil, organic solvents, resin solutions, resin-containing dispersions, printing It is suitable for transporting liquid components (or aqueous or oily fluids) such as ink and paint.
