(Embodiment 1)
FIG. 1 is a side view showing an example of a state in which an equipment storage / extraction apparatus according to an embodiment of the present invention is mounted on a transport vehicle, FIG. 2 is a plan view, and FIG. 3 is a rear view.

The equipment storage / extraction device 100 according to the present embodiment is mounted on a loading platform 901 of a transport vehicle 900 capable of self-propelled movement or towing movement with wheels 902.
In the following description of the present embodiment, in each figure, the X, Y, and Z directions are as illustrated, the traveling direction of the transport vehicle 900 is the X direction, and the height direction of the transport vehicle 900 is the Z direction. The width direction of the transport vehicle 900 will be described as the Y direction.

The equipment storage / extraction device 100 of this embodiment includes a moving frame 110, a turning frame 120, and a hydraulic system 130.
The moving frame 110 includes a rectangular frame base 111 installed on the entire upper surface of the loading platform 901, and a rectangular stacking unit 113 that is horizontally supported by four frame columns 112.

The frame pillars 112 are connected to each other by a connecting beam 112a arranged in a rectangular shape at a predetermined height from the frame base 111.
A moving wheel 114 is provided at the lower end of each of the frame columns 112, and the moving frame 110 is moved back and forth between the front end and the rear end of the loading platform 901 along the frame base 111 along the traveling direction of the transport vehicle 900. It is possible to move in the (X direction).

  The loading unit 113 has a width that is the same as the width of the loading platform 901, and the length is set to approximately half that of the loading platform 901. Therefore, when the moving frame 110 is moved to the front end of the loading platform 901 as shown in FIG. 1, an empty space is generated on the rear end side.

  A fixed rack 117 and a lower surface of the front half of the connecting beam 112a opposite to the upper surface of each of the upper half of the rear half of the two sides parallel to the longitudinal direction (X direction) of the frame base 111 and The moving racks 118 are arranged at predetermined intervals with the tooth surfaces facing each other in the vertical direction (Z direction) along the moving direction of the moving frame 110.

Between the fixed rack 117 and the movable rack 118, a movable pinion gear 116 is disposed so as to mesh with both.
Further, a frame moving hydraulic cylinder 115 (first moving mechanism) is provided at a free position on the tip side of the side where the fixed rack 117 of the frame base 111 is disposed, and the rod 115a of the frame moving hydraulic cylinder 115 is provided. The tip is connected to the above-described moving pinion gear 116.

  Then, the frame moving hydraulic cylinder 115 expands and contracts to drive the moving pinion gear 116 in the front-rear direction (X direction), so that the loading unit 113 supported by the frame column 112 of the moving frame 110 is supported with respect to the frame base 111. The carrier 901 is moved in the front-rear direction (X direction).

  On the other hand, stacking unit outer frames 119 are arranged at both ends in the width direction (Y direction) of the stacking unit 113 of the moving frame 110, and a plurality of revolving frames 120 (in this embodiment, Three sets of the first turning frame S1 to the third turning frame S3) are arranged.

  Since each of the plurality of first turning frames S1 to third turning frames S3 (turning frame 120) has a common configuration, only one turning frame 120 will be described. This is referred to as the swivel frame S3.

  Each swivel frame 120 includes a plurality of sign bases 121 that are arranged in parallel in the front-rear direction (X direction) of the loading platform 901 and whose lower portions are connected in the width direction (Y direction) by horizontal rails 121a.

Each of the sign holders 121 is provided with a U-shaped sign guide 128 that opens upward in a substantially parallel lying state with respect to the stacking unit 113.
Then, the traffic regulation sign 300 is loaded on the sign stand 121 by sandwiching the support pillar 302 of the traffic regulation sign 300 with the sign plate 301 fixed to the tip of the pillar 302 between the sign guides 128.

  The sign base 121 is supported by the loading unit 113 via a drive side link 122 (swivel link mechanism) whose front end is swingable in the front-rear direction (in the XZ plane), and the rear end is swingable. It is supported by the side edge part of the driven side link 123 via the driven side link 123 (turning link mechanism).

  Further, the middle of the driven side link 123 and the lower end of the drive side link 122 are connected to the drive connection link 124 (swivel link mechanism) so that the rocking displacement in the XZ plane is not restrained so as to be freely tilted and displaced. ing.

That is, the lower end of the drive connection link 124 is connected in common with the lower end of the drive side link 122.
In the case of the present embodiment, link guide rails 127 are provided on the rear end side of the stacking unit 113 in parallel with the front-rear direction (the left-right direction in FIG. 1), and between the link guide rails 127, the front-rear direction ( A link support carriage 126 (second movement mechanism) that moves in the X direction) is provided.

4 is a rear view showing a configuration example of the link support cart 126, and FIG. 5 is a side view showing a configuration example of the link support cart 126. As shown in FIG.
The link support carriage 126 includes wheels 126a sandwiched between the link guide rails 127, and can move in the front-rear direction while being restrained in the vertical movement by the link guide rails 127.

  And the lower end part of the drive side link 122 and the drive connection link 124 is connected to the link support carriage 126 via the link coupling pin 126c, and is supported by the link support carriage 126, thereby along the upper surface of the stacking section 113. The structure moves in the front-rear direction (X direction).

  Further, the tip of the rod 125a of the swing hydraulic cylinder 125 (second moving mechanism) disposed in parallel to the front and rear direction on the upper surface of the loading portion 113 is coupled to the rod coupling hole 126b of the link support carriage 126, and the swing hydraulic pressure is increased. The configuration is such that thrust in the front-rear direction of the cylinder 125 acts on the drive side link 122 and the link guide rail 127 via the link support carriage 126.

  That is, when the rod 125a of the swing hydraulic cylinder 125 extends to the rear of the loading platform 901 (right side in FIG. 1), the drive side link 122 and the drive connection link 124 connected to the link support carriage 126 load the sign receiving platform 121. From the lying state substantially parallel to the portion 113 (the state of the second turning frame S2 and the third turning frame S3 in FIGS. 2 and 3), it is pushed out rearward of the loading platform 901 so as to stand on the rear side of the loading platform 901. The parallel displacement and the turning displacement of the direction with respect to the loading platform 901 are combined and moved. This state is the first turning frame S1 of FIGS.

  On the contrary, when the rod 125a of the swing hydraulic cylinder 125 is retracted, the loading platform 901 is moved so that the sign receiving platform 121 shifts from the standing state at the rear of the loading platform 901 to the lying state on the loading section 113. The parallel displacement and the turning displacement with respect to the loading platform 901 in the direction of pulling forward are moved in combination.

FIG. 6 is a conceptual diagram illustrating a configuration example of a hydraulic system 130 that drives the revolving frame 120.
The hydraulic system 130 includes a hydraulic pressure supply pipe 131, a hydraulic pressure recovery pipe 132, a branch pipe 133, a branch pipe 134, a three-position switching valve 135, a pilot operation check valve 136 for each of the first swing frame S1 to the third swing frame S3. , A pilot operation check valve 137, a counter balance valve 138, and a fall prevention valve 139.

  The hydraulic pressure supply pipe 131, the hydraulic pressure recovery pipe 132, the branch pipe 133, the branch pipe 134, the three-position switching valve 135, the pilot operation check valve 136, the pilot operation check valve 137, and the counter balance valve 138 are in a block form that constitutes the hydraulic system 130. Can be formed integrally in the manifold M.

  The fall prevention valve 139 is disposed integrally with the swing hydraulic cylinder 125, and the branch pipe 133 and branch pipe 134 of the manifold M and the swing hydraulic cylinder 125 are connected by a flexible pipe 133a and a flexible pipe 134a.

The branch pipe 133 and the branch pipe 134 connect the two ports of the hydraulic pressure supply pipe 131, the hydraulic pressure recovery pipe 132, and the swing hydraulic cylinder 125.
The three-position switching valve 135 is interposed between the branch pipe 133 and the branch pipe 134, and is operated by an operator so that the branch pipe 133 and the branch pipe 133 are simultaneously shut off, and the branch pipe 133 and the branch pipe 134 are turned. The hydraulic cylinder 125 is operated in three positions of two switching positions in the connection (turning) direction of forward / reverse (that is, standing / falling of the sign holder 121).

  The pilot operation check valve 136 and the pilot operation check valve 137 provided in each of the branch pipe 133 and the branch pipe 134 detect the hydraulic pressure of the other branch pipe 134 and the branch pipe 133 as the pilot pressure, thereby performing the check operation. The oil flow is released to prevent backflow of the oil flow in one of the aforementioned forward / reverse directions.

  The counter balance valve 138 swivels in the direction in which the rod 125a of the swivel hydraulic cylinder 125 protrudes (that is, the swivel frame 120 that supports the sign base 121 swivels so as to stand up (tilt) behind the load carrier 901). The flow path resistance of the oil flowing out from the hydraulic cylinder 125 to the branch pipe 134 is controlled.

  Accordingly, the turning speed of the sign receiving base 121 is prevented from being excessively increased during the standing turn due to the weight of the traffic regulation sign 300 placed on the sign receiving base 121, and the turning operation of the smooth turning frame 120 is facilitated. Is realized.

  The fall prevention valve 139 is a pilot-synchronized emergency shut-off valve that operates by monitoring the hydraulic pressure of the branch pipe 134 (flexible pipe 134a) connected to the rod-side port of the swing hydraulic cylinder 125. For example, when the branch pipe 134 (flexible pipe 134a) connected to the turning hydraulic cylinder 125 is broken and the hydraulic pressure is lost, the turning of the rod 125a of the turning hydraulic cylinder 125 is locked to turn in the standing direction. The sign stand 121 inside is prevented from dropping suddenly due to the weight of the traffic regulation sign 300.

  Note that the frame moving hydraulic cylinder 115 of the moving frame 110 is also controlled by the hydraulic system 130, but since it is a simple reciprocating operation, the description of the hydraulic circuit is omitted, but the hydraulic pressure similar to that in the case of the turning frame 120 described above is used. A circuit can be used.

Hereinafter, an example of the operation of the equipment storage / extraction device 100 of the present embodiment will be described.
First, the loading operation of the traffic regulation sign 300 will be described.
In this case, the rod 125 a of the swing hydraulic cylinder 125 of the equipment storage / extraction device 100 is extended, and the moving frame 110 is moved to the rear end of the loading platform 901.

Thereafter, one swivel frame 120 (in this case, the sign base 121 of the first swivel frame S1) is swung clockwise in FIG.
This state is shown in FIGS. Then, the operator leans on the traffic regulation sign 300 with the sign plate 301 facing upward on the sign base 121 of the first turning frame S1 standing up behind the loading platform 901, and the traffic regulation sign. The upper part of the 300 pillars 302 is fitted into a U-shaped marker guide 128.

  As described above, in the case of the equipment storage / extraction device 100 of the present embodiment, it is only necessary to lean the traffic regulation sign 300 on the sign receiving base 121 during storage, and no heavy work is required to lift the traffic regulation sign 300. .

  Next, the sign support 121 of the first turning frame S1 holding the traffic control sign 300 is turned counterclockwise, and the traffic control sign 300 supported by the sign support 121 is moved from the standing state to the moving frame. Lay down to a position that is almost horizontal just above 110. The movement state of the traffic regulation sign 300 in this series of operations is illustrated in FIG.

If necessary, the same loading operation as that of the first turning frame S1 is also performed on the second turning frame S2 and the third turning frame S3.
Thereafter, the frame moving hydraulic cylinder 115 is actuated to move the moving frame 110 toward the front half of the loading platform 901. As a result, the lower end of the support post 302 of the traffic regulation sign 300 protruding from the rear end of the moving frame 110 (the sign receiving base 121) is drawn into the upper space of the loading platform 901 along with the movement of the moving frame 110. However, it will be in the state located on the loading platform 901, and the traffic control sign 300 does not protrude from the loading platform 901 during conveyance.

  This state is shown in FIG. As illustrated in FIG. 1, in the case of the equipment storage / extraction device 100 of the present embodiment, the presence of the sign plate 301 of the traffic regulation sign 300 makes it about half of the upper end side of the heavy column 302. The range is stably supported on the moving frame 110 in a state where the range is supported by the sign base 121, and the lower end side of the support column 302 is free.

  For this reason, in the equipment storage / extraction device 100 according to the present embodiment, the upper half of the traffic regulation sign 300 is supported by the sign cradle 121, thereby suppressing the turning height H of the traffic regulation sign 300 from the road when unloading. be able to.

  That is, when the traffic regulation sign 300 is supported over the entire length of the support 302, the turning radius when the traffic regulation sign 300 is shifted from the lying state to the standing state is approximately the total length of the support 302, the loading platform 901, and the moving frame 110. Therefore, a large empty space is required above the loading platform 901.

  On the other hand, in the case of the equipment storage / extraction device 100 of the present embodiment, the upper end side of the traffic regulation sign 300 is supported by the sign receiving base 121, and the lower end side of the column 302 can be freely moved, and is loaded and unloaded. As described above, the moving frame 110 is moved to the rear end of the loading platform 901, and the lower end of the column 302 of the traffic regulation sign 300 is projected into the empty space behind the loading platform 901.

  Further, the turning frame 120 combines the parallel displacement and the turning displacement between the lying position at the upper part of the moving frame 110 and the standing position at the side of the moving frame 110, and the traffic regulation loaded on the sign stand 121. The sign 300 is moved.

  For this reason, as shown in FIG. 7, there is almost no upward displacement of the traffic regulation sign 300 (sign board 301) at the time of turning on and off, and the height of the loading platform 901 of the transport vehicle 900 is the same as that of the traffic regulation sign 300. It can be effectively used to secure the swivel space on the lower end side of the free column 302, and the required swivel height H above the loading platform 901 in the unloading work can be greatly reduced.

  On public roads where traffic regulation signs 300 are supposed to be installed, there are cases where there is usually a height restriction for the purpose of preventing collision with the installation structure on the road, and considering such height restriction, The equipment storage / extraction device 100 of the present embodiment that can reduce the turning height H is extremely effective in handling the long traffic regulation sign 300.

  In FIG. 1, since the space surrounded by the rear half of the loading platform 901 and the frame support 112 below the loading unit 113 is an empty space, a traffic regulation substrate different from the traffic regulation sign 300 is efficiently loaded. be able to.

  It should be noted that the removal work at the installation site of the traffic regulation sign 300 is the reverse of the above-described procedure. In the case of the equipment storage / extraction device 100 according to the present embodiment, when the traffic regulation sign 300 is taken out, the sign rest 121 is turned upright by the swivel frame 120 so that the traffic restriction mounted on the sign rest 121 is placed. The sign 300 stands up on the road at the rear end of the loading platform 901 as in the first turning frame S1 of FIG.

  For this reason, the worker only needs to carry the standing traffic regulation sign 300 horizontally, and it is necessary to perform a heavy load work for moving the traffic regulation sign 300 up and down, as in the case of the loading operation described above. The work efficiency can be improved by reducing the workload and shortening the required time.

  Further, by providing the turning frame 120 on the moving frame 110, a part of the entire length of the traffic regulation sign 300 that moves parallel and turns on the moving frame 110 is covered by the height of the moving frame 110 as described above. Therefore, the length of the drive side link 122, the driven side link 123, and the drive connection link 124 that constitute the turning frame 120 can be shortened with respect to the total length of the traffic regulation sign 300 that is assumed. Contributes to the suppression of H.

  In addition, since the lengths of the drive side link 122, the driven side link 123, the drive connection link 124, and the like constituting the turning frame 120 can be shortened, the equipment storage / extraction device 100 can be reduced in size, weight, and cost.

Further, the downsizing of the swivel frame 120 has the advantage that the rated power of the hydraulic system 130 that drives the swivel frame 120 can be reduced and the cost can be reduced.
In addition, since the plurality of first turning frames S1 to S3 are arranged on the moving frame 110 so that each of the first turning frames S1 to S3 can operate independently, a plurality of mounted on each of the moving frames 110 according to installation specifications and work procedures. There is also an advantage that various and detailed loading / unloading operations of the traffic regulation sign 300 are possible.

FIG. 10 is a rear view, and FIG. 10 is a plan view showing a configuration example of an equipment storage / extraction device according to another embodiment of the present invention.

  In the equipment storage / extraction apparatus 100 that handles the traffic regulation sign 300 described above, the latter half of the loading platform 901 of the transport vehicle 900 is an empty space. Therefore, an example will be described in which the rubber cone arrangement collection support device 200 that supports the arrangement of the rubber cone 400 by effectively using the empty space is provided in parallel.

  Note that there is Japanese Patent Application No. 2002-34659 filed by the applicant of the present invention for a single rubber cone arrangement collection support apparatus 200, and the rubber cone arrangement collection support apparatus 200 described below has the same configuration as that of the prior application. .

The rubber cone arrangement collection support device 200 includes a swing / retraction unit 210 and a gripping operation unit 220.
As shown in FIG. 9, the swing / retreat unit 210 includes a carriage unit 211 that can be moved by a moving wheel 212 on a guide rail 216 laid in the width direction (Y direction) of the loading platform 901.

  On this carriage section 211, a swing shaft 214 is provided whose base end is horizontally supported by a pair of swing bearings 213 in the width direction of the loading platform 901. The swing shaft 214 is a swing hydraulic cylinder. It is rotated by 215.

  The upper end of the swing arm 221 of the gripping operation unit 220 is fixed to the outer end portion of the swinging shaft 214, and the entire gripping operation unit 220 swings around the swinging shaft 214 as the swinging shaft 214 rotates. To do.

  The side surface of the clamp head 222 is supported in the middle of the swing arm 221 in the length direction, and the rubber cone 400 is opened and closed by opening and closing the clamp head 222 around a direction parallel to the axial direction of the swing arm 221. The base end portions of the plurality of clamp fingers 223 that perform the gripping operation and the releasing operation of the top portion are supported.

  The clamp finger 223 is opened and closed by being driven by a clamp hydraulic cylinder 225 provided coaxially on a surface opposite to the mounting surface of the clamp finger 223 in the clamp head 222.

  Further, a guide bar 224 is fixed to the swing arm 221 at a position surrounding the large-diameter lower end portion of the rubber cone 400 whose top is gripped by the clamp finger 223 in a U-shape with a predetermined gap.

As shown in FIG. 8, the guide bar 224 is installed so as to open toward the rear of the loading platform 901 when the swing arm 221 is positioned vertically below the loading platform 901.
Hereinafter, the operation of the rubber cone arrangement collection support device 200 provided in parallel with the equipment storage / extraction device 100 will be described.

  First, when not in use, the rubber cone arrangement / recovery support device 200 is configured so that the swing arm 221 of the gripping operation unit 220 is in a horizontal posture and the carriage 211 of the swing / retreat unit 210 is placed at the center in the width direction of the loading platform 901. By being moved, the moving frame 110 is pulled into a position where it does not interfere with the movement of the frame support 112 and the like.

A plurality of rubber cones 400 are mounted in an empty space on the loading platform 901 that does not interfere with the movement of the moving frame 110 and the swing / retreat unit 210.
When the rubber cone 400 is installed, the operator rides on the loading platform 901 and moves the carriage 211 of the swing / retraction unit 210 to the side end of the loading platform 901 as shown in FIG. 220 protrudes to the outside of the side of the loading platform 901.

  Then, while the transport vehicle 900 is moved forward at a predetermined speed, a hydraulic system (not shown) is operated to make the swing arm 221 horizontal and hold the top of the rubber cone 400 between the clamp fingers 223.

  Thereafter, when the swing arm 221 is rotated clockwise in the vertical direction as shown in FIG. 8 by the swing hydraulic cylinder 215 and the clamp finger 223 is released by the clamp hydraulic cylinder 225, the rubber cone 400 is placed on the road surface by its own weight. It is arranged by landing and leaving behind between the guide bars 224 opened in a U-shape rearward in the traveling direction.

By setting the horizontal length of the guide bar 224 according to the traveling speed of the transport vehicle 900, the rubber cone 400 that is left behind is prevented from falling.
The arrangement interval of the rubber cones 400 can be freely set according to the traveling speed of the transport vehicle 900 and the timing at which the rubber cones 400 are inserted into the gripping operation unit 220.

  Contrary to the above, the rubber cone 400 on the road is collected in a state where the transport vehicle 900 is moved backward with the gripping operation unit 220 vertical as shown in FIG. After the rubber cone 400 enters, the clamp finger 223 is closed and the top is gripped, and then the swing arm 221 is rotated to the horizontal position at the height of the loading platform 901 to release the clamp finger 223 so that the operator can The rubber cone 400 is collected on the loading platform 901.

  As described above, in the rubber cone arrangement / collection support device 200, the worker can place and collect the rubber cone 400 without getting off the road while getting on the loading platform 901.

  As described above, in the second embodiment, in the loading platform 901, the rubber cone arrangement collection support device 200 is arranged in parallel in the latter half of the loading platform 901 that becomes an empty space by the movement of the moving frame 110 in the equipment storage / extraction device 100. Thus, there is an advantage that the traffic regulation sign 300 and the rubber cone 400 can be efficiently installed and collected by the single transport vehicle 900.

First, from the initial state of FIG. 15, the movable carriage 11 is driven by the thrust of the chain 12 that travels by the drive motor 2, and starts moving to the rear of the truck 20.

  At this time, in the sign receiving frame 3, the long hole portion 3a moves through the slide roller 6 fixed to the turning arm 4, and the slide roller 6 reaches the upper end portion of the long hole portion 3a as shown in FIG.

  At this time, as illustrated in an enlarged manner in FIGS. 18 and 19, the stopper arm 16 locks the end of the elongated hole portion 3 a of the sign receiving frame 3 by the stopper spring 19 simultaneously with the turning of the turning arm 4, Prevent separation during turning. Thereby, the turning motion of the sign 18 held by the sign receiving frame 3 is smoothly performed.

  Then, with the upper end portion of the swivel arm 4 fixed to the left end portion of the elongated hole portion 3a, the thrust of the sign receiving frame 3 is transmitted to the swivel arm 4, and the swivel arm 4 has a lower end as shown in FIG. The sign receiving frame 3 supported by the swivel arm 4 and the arm 13 and the sign 18 held on the sign receiving frame 3 are rotated about 90 degrees around the swivel shaft 7 in a direction away from the main body frame 1. Stands substantially vertically behind the track 20.

A shock absorber 22 is provided at the rear end of the truck 20 and receives the lower surface of the sign receiving frame 3 that revolves with inertia while relaxing the impact.
This state is shown in FIG. Then, the operator relaxes the marker clamp screw 24 so that the marker 18 is taken out from the marker receiving frame 3 and installed at a desired location.

The loading of the sign 18 onto the sign receiving frame 3 and the loading onto the truck 20 are performed in the reverse order of the above-described operation.
As described above, according to the apparatus of the third embodiment, it is possible to reduce the work of loading and unloading the mark 18 on the truck 20.

  Needless to say, the present invention is not limited to the configuration exemplified in the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
