Description

  The present invention relates to a transporting method that can be suitably used to transport a heavy article of several tens to several hundreds kg, such as an outdoor unit of an air conditioner.

  In recent years, a multi-type air conditioner in which a plurality of indoor units are connected to a large-capacity outdoor unit by a refrigerant pipe is used in a relatively large facility such as a building or a large store. An outdoor unit in this type of air conditioner is manufactured, for example, in a factory and then transported to a delivery destination by a truck, and is transported from the truck to a predetermined installation location or storage location at the delivery destination. The transportation of outdoor units in factories and customers is usually performed using forklifts, cranes, etc., but must be performed manually in places where these cannot be used. However, since the outdoor unit is a heavy article that can reach several hundred kg, it requires several workers to carry it by hand, and the work requires a lot of time and labor.

  In addition to the outdoor unit as described above, there is generally a method of using a carriage to transport heavy objects with a small amount of labor. For example, in Patent Document 1 below, a lifting device (towing cart) including a long pallet in which the bottom surfaces of both short sides are integrated with a crosspiece and a fork that lifts and lowers the long pallet by operating a hydraulic jack is supported. ) And a pair of support carts that are detachably disposed on the bottom surface of the long pallet to support and support the casters (carrier vehicles) are disclosed. (See claim 1).

  In the cart of Patent Document 1, the fork of the lifting device is inserted into the lower surface of the long pallet, the fork is lifted by a hydraulic jack to lift the entire long pallet, and a pair of support carts are inserted below the long pallet. The long pallet is placed on the pair of support carts by lowering the long pallet. As a result, the long pallet is supported by the support carriage, and the heavy objects on the long pallet can be easily transported by a small number of workers.

Japanese Patent Laid-Open No. 8-119591

  In the technique of the above-mentioned Patent Document 1, the support carriage cannot be inserted below the long pallet unless it is lifted up. Therefore, a lifting device having a fork that is lifted and lowered by a hydraulic jack is required to lift the long pallet. Such a lifting device is large, heavy, expensive, and expensive. In addition, when it is necessary to transport not only in factories and the like, but also in delivery destinations as in the outdoor unit described above, there is a request to carry a lifting device on a truck along with a heavy load. It is difficult for the lifting device of 1 to meet such a request.

  The present invention has been made in view of the above circumstances, and can easily lift a mounting table on which a transported object is placed, fix the carriage on the mounting table, and transport the transported object. The purpose is to provide a transportation method.

The transport method of the present invention includes a lifting step of lifting a part of the mounting table on which the object to be transported is lifted by a lifting tool using a lever,
The mounting step of fixing the divided carriage to a part of the mounting table lifted by the lifting tool is performed on a plurality of locations of the mounting table,
It is a transporting method for moving an object to be transported placed on the mounting table by the plurality of divided carriages fixed to the mounting table,
Further, the lifting tool is applied to the grounding portion that serves as a fulcrum of the lever by grounding on the road surface, an operating portion to which an operating force is applied in a swinging direction using the grounding portion as a fulcrum, and the operating portion. An operating part that causes the operating table to act on the mounting table to lift the mounting table,
The grounding portion includes a roller that can roll in a direction of relative movement with respect to the action portion when lifting the mounting table.

  According to the carrying method of the present invention, since the placing table for placing the object to be carried is lifted by a lifting tool using a lever for each part and the divided carriage is fixed, the lifting tool having a simple configuration is used. Can be used. Therefore, the lifting tool can be reduced in size and weight, and can be carried on a truck or the like together with the object to be transported. In addition, since the lifting tool has a roller on the grounding part, the grounding part can be easily moved on the road surface to smoothly lift the mounting table, and the grounding part damages the road surface and the floor surface. Can be prevented.

It is preferable that a plurality of the rollers are provided in a direction orthogonal to the relative movement direction.
According to this configuration, the posture of the lifting tool in the direction orthogonal to the relative movement direction of the grounding portion with respect to the action portion (hereinafter simply referred to as “orthogonal direction”) can be held by the plurality of rollers. Therefore, the lifting tool does not fall down in the orthogonal direction when the mounting table is lifted, and the mounting table can be lifted in a stable state.

It is preferable that the lifting tool includes a stopper portion that limits a swing operation amount of the operation portion when the action portion lifts the mounting table to a predetermined height.
According to this configuration, the mounting table can be appropriately lifted to a predetermined height.

It is preferable that the stopper portion restricts a swing operation amount of the operation portion at a position where the grounding portion exceeds the action portion with respect to the relative movement direction.
According to this configuration, when the operation unit is swing-operated to a position limited by the stopper unit, the mounting table can be maintained in a lifted state even if the operation unit is not supported manually. Therefore, the worker who performed the work of lifting the mounting table can also perform the work of fixing the divided carriage to the mounting table.

It is preferable that the action part and the stopper part are formed symmetrically with respect to each other with respect to an axis of symmetry passing through the axis of the grounding part.
With such a configuration, the action part and the stopper part can be used together.

The split carriage is a fixed portion that is detachably fixed to the outer peripheral portion of the mounting table,
You may provide the at least 2 wheel respectively arrange | positioned at the inner side and the outer side of the said outer peripheral part in the state which the said fixing | fixed part was being fixed to the outer peripheral part of the mounting base.
Since the cart of the above-mentioned patent document 1 supports the long pallet by placing the long pallet on the support cart, each support cart is required to be able to maintain its own posture (being able to stand on its own). . For this reason, the support carriage of Patent Document 1 includes a large area base on three casters arranged in a triangular shape, and is large and heavy. On the other hand, since the divided carriage having the above-described configuration includes a fixed portion that is fixed to the outer peripheral portion of the mounting table, it can be used in a state of being fixed to the mounting table, and even if it cannot stand alone Good. Therefore, each divided carriage can be reduced in size and weight, and can be carried along with the object to be transported in the same manner as the lifting tool. In addition, since the divided carriage includes at least two wheels that are respectively arranged on the inner side and the outer side of the outer peripheral portion of the mounting table, the mounting table on which the object to be transported is stably supported. .

  According to the transporting method of the present invention, it is possible to easily lift the mounting table on which the object to be transported is mounted, fix the carriage on the mounting table, and transport the object to be transported.

The left and right frame members 15a are fixed on both ends of the front and rear frame members 15b. The front end portion and the rear end portion of the left and right frame members 15a protrude from the front and rear frame members 15b, respectively. Therefore, recesses 18 are formed on the lower surfaces of the left and right ends of the front portion and the rear portion of the mounting table 14. The recess 18 is used to engage a lifting tool 45 described later. The mounting table 14 has a structure composed of only rectangular outer peripheral frames (frame members) 15a and 15b, but is formed in a lattice shape by passing other frame members inside the outer peripheral frames 15a and 15b. May be. Further, the mounting table 14 may be integrally provided with another frame member that surrounds the entire outer surface of the object to be transported 10.

FIG. 1 is a schematic plan view showing a transport cart that can be used in the transport method according to an embodiment of the present invention, and a first example of a lifting tool used for mounting the transport cart. is there.
The transport cart 20 of this example is composed of a plurality of, specifically four, split carts 21. Then, the carriage 20 can carry the outdoor unit 10 placed on the mounting table 14 by mounting four divided carriages 21 on the outer periphery of the mounting table 14, respectively. The split carriage 21 includes two left and right first split carriages 21a mounted on the rear side of the mounting table 14 in the front-rear direction (transport direction A), and two left and right second split carriages 21b mounted on the front side. It is made up of.

FIG. 2 is a side view of the first divided carriage 21a, and FIG. 3 is a plan view of the first divided carriage 21a. In addition, the description of "front" and "rear" shown in FIG.2 and FIG.3 respond | corresponds to the front-back direction (conveyance direction A) in FIG.
The first divided carriage 21a includes a pair of wheels 23a and 23b, a connecting member 24 that connects the pair of wheels 23a and 23b, and a fixing portion 25 provided between the pair of wheels 23a and 23b. The one (front side) wheel 23a is a so-called caster wheel (universal wheel), and is configured to be rotatable around a rotation shaft 26 in the vertical direction. The rotating shaft 26 of the wheel 23 a is attached to one end (front end) of the connecting member 24. The other (rear) wheel 23 b is a fixed wheel and is attached to the other end (rear end) of the connecting member 24.

  The connecting member 24 includes a standing wall 27 provided in the middle of the pair of wheels 23a and 23b, a mounting arm 28 extending forward from the standing wall 27, and a mounting bracket 29 projecting rearward from the standing wall 27. The attachment arm 28 is formed of an elongated strip, and a shaft support portion 30 for attaching the rotating shaft 26 of the wheel 23a is provided at the tip portion thereof. The mounting bracket 29 is formed in a U-shape from the left and right plates and the upper plate, and a wheel 23b is mounted inside.

  The fixing portion 25 includes a pair of upper and lower clamping members 32 and 33. The fixing portion 25 is fixed to the mounting table 14 by holding the outer peripheral portion (frame member 15b) of the mounting table 14 with a pair of holding members 32 and 33. The lower clamping member (hereinafter also referred to as “lower clamping member”) 33 is formed in a flat plate shape and extends forward from the lower end of the standing wall 27. Specifically, the standing wall 27 and the lower clamping member 33 are integrally formed of L-shaped steel. The upper clamping member (hereinafter also referred to as “upper clamping member”) 32 is made of a rectangular plate, and is attached so as to be swingable up and down around a support shaft 34 attached to a side surface of the attachment arm 28.

  A lever member 36 extending rearward and obliquely upward is provided on the upper surface of the upper clamping member 32, and an urging member 37 formed of a tension coil spring is provided between the lever member 36 and the lower clamping member 33. The upper clamping member 32 is urged downward (lower clamping member side) by the urging member 37 with the support shaft 34 as a fulcrum. Further, the lever member 36 is set to a downward swing limit by contacting a lower edge of a rectangular notch 38 formed in the standing wall 27. When the lever member 36 is at the lower swing limit position, the distance between the lower end of the upper clamping member 32 and the upper end of the lower clamping member 33 is smaller than the thickness of the frame member 15 b of the mounting table 14.

  As shown in FIG. 2, the frame member 15 b of the mounting table 14 is inserted in the direction of arrow D between the upper clamping member 32 and the lower clamping member 33. At this time, the end of the frame member 15b abuts on the upper clamping member 32, so that the upper clamping member 32 rotates upward around the support shaft 34 against the biasing member 37, and the upper clamping member 32 and the lower clamping member are sandwiched. Insertion of the frame member 15b between the member 33 is allowed. The first divided carriage 21a is fixed to the frame member 15b by inserting the frame member 15b to a position where the frame member 15b comes into contact with the standing wall 27.

  When the frame member 15b is to be detached from between the upper clamping member 32 and the lower clamping member 33 in the direction opposite to the arrow D, the front end portion (locking portion) 32a of the upper clamping member 32 is strongly against the upper surface of the frame member 15b. Press to lock. Thereby, the detachment of the frame member 15b from between the upper clamping member 32 and the lower clamping member 33 is prevented. That is, the fixing portion 25 includes a separation preventing mechanism that allows the frame member 15b to be inserted between the pair of sandwiching members 32 and 33 and restricts the separation of the frame member 15b. By such a detachment prevention mechanism, the frame member 15b can be easily inserted between the upper clamping member 32 and the lower clamping member 33, and the frame member 15b is prevented from detaching between the two. The first divided carriage 21a can be reliably fixed to the member 15b. In order to disengage the frame member 15b from between the upper clamping member 32 and the lower clamping member 33 (to remove the first divided carriage 21a from the frame member 15b), the lever member 36 is swung upward by hand. The upper clamping member 32 may be separated from the upper surface of the mounting table 14.

  As shown in FIG. 1, the left and right first divided carriages 21 a are formed in a symmetrical shape. And each lever member 36 of each 1st division | segmentation cart 21a is located in the outer side of the left-right direction. Therefore, when the first divided carriage 21a is removed from the frame member 15b of the mounting table 14, the lever member 36 can be easily operated.

4 is a side view of the second divided carriage 21b, and FIG. 5 is a plan view of the second divided carriage 21b. Note that the descriptions “front” and “rear” shown in FIG. 4 correspond to the front-rear direction (transport direction A) in FIG. The second divided carriage 21b is attached to the mounting table 14 in the direction opposite to the first divided carriage 21a with respect to the front-rear direction.
The second divided carriage 21b has substantially the same configuration as the first divided carriage 21a already described, but differs in that the wheels 23b are caster wheels. That is, the wheel 23b of the second divided carriage 21b is configured to be rotatable around the rotary shaft 41 in the vertical direction. The connecting member 24 includes a mounting arm 42 that extends forward from the standing wall 27 instead of the mounting bracket 29, and a shaft support 43 that rotatably mounts the rotary shaft 41 is provided at the tip of the mounting arm 42. Yes. Since the other configuration is the same as that of the first divided carriage 21a, detailed description thereof is omitted.

  In order to attach the first divided carriage 21a and the second divided carriage 21b to the mounting table 14, it is necessary to lift the mounting table 14 and make it float from the ground. Therefore, in the transport method according to the present embodiment, as shown in FIG. 1, a lifting tool 45 using “lever” is used. Two lifting tools 45 are used as one set. When the first divided carriage 21a is mounted on the rear side of the mounting table 14, the rear side of the mounting table 14 is lifted by the two lifting tools 45, When the second divided carriage 21 b is mounted on the front side of the mounting table 14, the front side of the mounting table 14 is lifted by the two lifting tools 45. The two lifting tools 45 have exactly the same structure, but are used in a state of being opposite to each other in the left-right direction.

FIG. 6 is a side view of the lifting tool 45, and FIG. 7 is a front view of the lifting tool 45.
The lifting tool 45 used in the present embodiment includes an operation lever (operation part) 47, an action member (action part) 48, a support roller (grounding part) 49, and a stopper member 50.
The operation lever 47 is a long member formed of a pipe material or the like, and on the upper side thereof, a grip portion 51 that is held by the operator's hand to provide an operation force is provided. An action member 48 and a stopper member 50 are fixed to the lower end portion of the operation lever 47.

  The action member 48 is formed of a rectangular plate material that is long in the left-right direction. On the other hand, the stopper member 50 is also formed of a rectangular plate having the same dimensions as the action member 48. And the action member 48 and the stopper member 50 are mutually arrange | positioned at an angle of about 90 degrees-100 degrees, and the lower end parts are connected. A square-shaped connecting plate 53 is fixed to one side of the action member 48 and the stopper member 50 in the left-right direction, and this connecting plate 53 is fixed to the lower end of the operation lever 47.

  As shown in FIG. 6, the action member 48 and the stopper member 50 are arranged in line symmetry with respect to an axis of symmetry X passing through the center of the support roller 49 along the operation lever 47. The action member 48 and the stopper member 50 are in a relationship of being shared with each other. That is, when one is used as the action member 48, the other is used as the stopper member 50, and when the other is used as the action member 48, one is used as the stopper member 50. Specific actions of the action member 48 and the stopper member 50 will be described later. Further, the support roller 49 is attached to a connection portion (lower end portion) of the action member 48 and the stopper member 50. In the present embodiment, as shown in FIG. 7, the two support rollers 49 are attached at intervals in the left-right direction so as to protrude outward from the action member 48 and the stopper member 50 in the left-right direction. .

FIG. 8 is an explanatory view showing the operation of the lifting tool 45.
In order to lift the mounting table 14 with the lifting tool 45, first, as shown in FIG. 8A, the action member 48 is inserted into the recesses 18 formed on the left and right sides of the mounting table 14. When the operation lever 47 is swung in the direction of arrow B with the support roller 49 as a fulcrum, the action member 48 is swung upward with the support roller 49 as a fulcrum, and the tip 48a of the action member 48 is the lower surface of the frame member 15a. To lift the end of the mounting table 14 (see FIG. 8B). The support roller 49 rolls in the direction of arrow C relative to the tip 48 a of the action member 48 in the process of lifting the mounting table 14.

  As shown in FIG. 8B, when the support roller 49 rolls to a position beyond the tip 48a of the action member 48, the stopper member 50 comes into contact with the ground and the swing of the operation lever 47 is restricted. . At this time, since the tip end portion (action point) 48a of the action member 48 is disposed between the contact point 49a of the support roller 49 and the contact point 50a of the stopper member 50, the load of the mounting table 14 is applied to the action point 48a. On the other hand, even if it works downward, the action member 48 does not return to the original position with the support roller 49 as a fulcrum, and the posture of the lifting tool 45 is maintained. Further, since the support roller 49 is provided on both the left and right sides of the action member 48 and the stopper member 50, the posture of the lifting tool 45 in the left-right direction is also maintained. Therefore, even when the operator releases his hand from the operation lever 47, the state where the mounting table 14 is lifted is maintained, and the worker who operates the lifting tool 45 can also perform the mounting work of the divided carriage 21.

FIG. 9 is an explanatory diagram showing a procedure for mounting the transport carriage on the mounting table.
As shown in FIG. 9, in order to attach the divided carriages 21 a and 21 b to the mounting table 14, first, the front and rear of the mounting table 14, here, the rear part of the mounting table 14 is lifted by the lifting tool 45. That is, the action member 48 of the lifting tool 45 is engaged with the recess 18 formed in the rear portion of the mounting table 14, and the operation lever 47 is swung to lift the rear portion of the mounting table 14 (FIGS. 9A and 9). (See (b)).

  Next, the wheel 23a of the first divided carriage 21a is inserted into the opening 57 (see FIG. 10) formed between the frame member 15b of the mounting table 14 lifted by the lifting tool 45 and the outdoor unit 10, and the first The fixing portion 25 of the one-segment carriage 21a is fixed to the frame member 15b of the mounting table 14 (see FIG. 9C). In addition, the dimension of the wheel 23a of the 1st division | segmentation carriage 21a and the shaft support part 30 is set as one condition that it can insert in the opening 57. FIG.

  Next, the lifting tool 45 removed from the rear portion of the mounting table 14 is engaged with the recess 18 formed in the front portion of the mounting table 14. Then, the operation lever 47 is swung to lift the front portion of the mounting table 14, and the fixing portion 25 of the second divided carriage 21 b is fixed to the frame member 15 b of the mounting table 14 in the same procedure as the first divided carriage 21 a ( (Refer FIG.9 (d)). Thereafter, the lifting tool 45 is removed from the mounting table 14 to ground the second divided carriage 21b, so that the outdoor unit 10 can be transported by the first and second divided carriages 21a and 21b. In addition, what is necessary is just to perform said operation | movement in a reverse procedure, in order to remove the 1st, 2nd division car 21a, 21b from the mounting base 14. FIG.

  The transport cart 20 used in the present embodiment can transport the outdoor unit 10 with a small number of people and a small amount of labor by mounting a plurality of split carts 21 a and 21 b on the mounting table 14. Since each divided carriage 21 is used while being fixed to the mounting table 14, it may not be able to stand alone when removed from the mounting table 14, and the two wheels 23 a and 23 b are connected by the connecting member 24. However, it can be formed in a very simple structure (see FIGS. 2 to 5). Therefore, the division cart 21 can be reduced in size and weight. Further, since the lifting tool 45 uses a lever, it can be configured with a very simple structure and light weight. Therefore, the divided carriages 21a and 21b and the lifting tool 45 can be easily carried. Therefore, when the outdoor unit 10 is transported from the factory to the delivery destination, the divided carriages 21a and 21b and the lifting tool 45 can also be transported together, so that the outdoor unit 10 can be transported in the factory, on the truck bed. The transport cart 20 and the lifting tool 45 can be suitably used for movement, transport at a delivery destination, and the like.

As shown in FIG. 1, the wheels 23b of the first divided carriage 21a attached to the mounting table 14 are fixed wheels, and the wheels 23a of the first divided carriage 21a and the wheels 23a, 23b of the second divided carriage 21b are casters. Since it is a ring, the wobbling can be suppressed by the fixed wheel while the direction of transportation can be easily changed by the caster wheel.
As shown in FIGS. 2 and 4, the fixing portion 25 is configured to sandwich the frame member 15 b of the mounting table 14 from above and below by the upper clamping member 32 and the lower clamping member 33. Can be fixed. Further, the upper holding member 32 is provided so as to be swingable by the support shaft 34, and its tip end portion 32 a is configured to be locked to the upper surface of the frame member 15 b, so that the upper holding member 32 and the lower holding member 33 are The frame member 15b can be inserted between the frames, and the frame member 15b can be prevented from being detached from the space. Accordingly, it is possible to suitably prevent the fixing portion 25 from being detached from the frame member 15b while the fixing portion 25 can be easily fixed to the frame member 15b of the mounting table 14.

  As shown in FIGS. 2 and 4, the fixing portion 25 of the divided carriages 21 a and 21 b is disposed below the attachment arm 28 in the connecting member 24, so that the height h of the mounting table 14 from the ground is set. It can be as low as possible. Therefore, the outdoor unit 10 can be transported in a stable state.

  As shown in FIG. 1, the load of the outdoor unit 10 is supported by each of the divided carriages 21 a and 21 b via a square mounting table 14. In each of the divided carriages 21a and 21b, a fixed portion 25 fixed to the frame member 15b of the mounting table 14 is provided between the two wheels 23a and 23b, and one wheel 23a is disposed inside the frame member 15b, and the other Since the wheel 23b is disposed outside the frame member 15b, the load from the outdoor unit 10 can be received by the two wheels 23a and 23b in a well-balanced manner. Therefore, the outdoor unit 10 can be transported in a more stable state.

  In addition, each of the divided carriages 21a and 21b has one wheel 23a disposed inside the frame member 15b and the other wheel 23b disposed outside the frame member 15b, so that the inner wheel from the position of the outer wheel 23b. The position of 23a can be grasped. Therefore, for example, when the road surface is uneven, it is possible to pass the inner wheel 23a while avoiding the unevenness.

FIG. 11 is a side view showing a second example of the transport cart.
The transport cart 20 of this example is different from the first example described above in the configuration of the fixing portion 25 of the split cart 21. Specifically, in the first example, the upper clamping member 32 is configured to be swingable about the support shaft 34, whereas in the present example, the upper clamping member 32 is movable in the vertical direction. It is attached to the lower end of the bolt 59. The bolt 59 is screwed into a horizontal plate 60 that is disposed to face the upper portion of the lower clamping member 33. The horizontal plate 60 is integrated by the lower clamping member 33 and the vertical plate 61. Therefore, in this example, the frame member 15b of the mounting table 14 is inserted between the upper clamping member 32 and the lower clamping member 33, and the upper clamping member 32 is lowered by turning the bolt 59, so that the lower clamping member 33 The frame member 15b is sandwiched between them. Thereby, the divided carriage 21 can be fixed to the frame member 15b.

In this example, it is necessary to operate a bolt 59 for sandwiching the frame member 15b between the upper clamping member 32 and the lower clamping member 33. Therefore, it can be said that the first example is more advantageous in terms of workability of mounting the divided carriage 21 on the mounting table 14.
Further, in the divided carriage 21 of this example, since the fixing portion 25 is provided on the upper side of the connecting member 24 that connects the pair of wheels 23a and 23b, the height h of the mounting table 14 to which the fixing portion 25 is fixed is set. It is higher than the first example (see FIG. 2). Therefore, it can be said that the first example is more advantageous in terms of transportation stability.

FIG. 12 is a side view showing a state in which the transport cart is fixed to another type of mounting table.
The mounting table 14 shown in the first and second examples is composed of four frame members 15a and 15b arranged in a square shape, but the mounting table 14 shown in FIG. 12 is a so-called pallet. A portion on which the object to be transported 10 is placed is formed by arranging a plurality of base plates 64 side by side, and a space 65 for inserting a fork such as a forklift is formed below the portion. In the example shown in FIG. 12, the divided carriage 21 of the second example is fixed to the base plate 64 portion of the mounting table 14.

Further, in such a pallet type mounting table 14, it is also possible to fix the divided carriage 21 to the frame member 66 located at the lowermost end.

FIG. 13 is a plan view showing another example of use of the transport cart.
FIG. 13 shows an example in which the split carriage 21 is used for the mounting table 14 having a large vertical / horizontal dimension ratio. When the divided carriage 21 is attached to such a mounting table 14, if the divided carriages 21 are attached to the left and right sides of the front and rear frame members 15 b as in FIG. 1, the stability in the left-right direction is deteriorated. Therefore, in the present embodiment, the divided carriages 21 are respectively attached to the front side and the rear side of the left and right frame members 15a. Thereby, the outdoor unit 10 on the mounting table 14 can be transported in a state where the stability in the left-right direction is ensured. The split carriage 21 mounted on the mounting table 14 is a second split carriage 21b in which all wheels 23a and 23b are caster wheels so as to be able to be transported forward (in the direction of arrow A). It is necessary to use FIG. 4 and FIG.

The present invention is not limited to the above-described embodiments, and can be appropriately changed within the scope of the invention described in the claims.
For example, although the example which conveys the outdoor unit 10 of an air conditioning apparatus was shown in the said embodiment, also when conveying another heavy article as a to-be-conveyed object, it can utilize the conveyance trolley | bogie 20 of this invention. it can.

  In the above embodiment, the fixed portion 25 of the split carriage 21 is configured to sandwich the frame members 15a and 15b of the mounting table 14 from above and below by the pair of sandwiching members 32 and 33. However, the frame members 15a and 15b It can be set as the structure clamped from front and back or right and left. The fixing unit 25 is not limited to the configuration in which the frame members 15a and 15b of the mounting table 14 are clamped by the pair of clamping members 32 and 33. For example, a fixing pin or the like is inserted between the divided carriage 21 and the frame members 15a and 15b. Various configurations such as a configuration in which the belt is provided on the divided carriage 21 and a configuration in which the belt is wound around the frame members 15a and 15b and fixed can be employed.
