Description

  The present invention relates to transportation of an automobile vehicle or a freight cargo, and in particular, relates to a transportation device capable of stably transporting a heavy object or a cargo having a large depth without touching anything other than the bottom surface and wheels.

Conventionally, large cargoes and heavy cargoes are lifted and transported in large numbers, or are transported using large cranes or forklifts. Large pieces of furniture were carried by a few people or by blankets being chewed underneath.
When removing accident vehicles and violating vehicles, it was necessary to lift the entire heavy vehicle with a crane and replace it with a transport vehicle. When moving a violating vehicle, there was a risk that the hooks and ropes of the crane would be in contact with the vehicle body and damage the vehicle body.

When an automobile vehicle or heavy cargo is to be lifted and transported by, for example, a forklift, it has been necessary to make the forklift truck body extremely heavy to counter the weight. Further, when lifting a deep cargo with a forklift, it is necessary to lengthen the fork, so the strength of the fork had to be extremely increased.
In order to solve this problem, Patent Document 1 discloses a device for carrying a stable fork by placing a fork at the tip of an arm having a fulcrum behind the carriage and lifting the cargo so that the center of gravity is on the carriage. It is disclosed. According to this apparatus, since the center of gravity of the cargo is on the carriage during transportation, it is stable. However, it is necessary to lift the entire heavy cargo to a high position, and there is a problem that it takes time to lift the cargo on the fork and then to the upper side of the carriage.

On the other hand, it is necessary to install a complicated mechanism as a storage unit or use a pallet separately for a device for taking in and out a vehicle in a mechanical multistory parking lot. In addition, in the gondola parking lot, a large strength was required to support the whole, and when empty buckets were mixed, a large force was required to maintain balance and rotate the gondola. In the puzzle-type parking lot, it took time to rearrange the stored vehicle pallets in a complex manner.
Japanese Patent Laid-Open No. 6-1000029

  Therefore, the problem to be solved by the present invention is that a heavy-weight moving device or a heavy-weight moving carriage having a light and simple structure that can stably lift and transport a heavy and heavy cargo without touching anything other than the bottom surface and wheels. Is to provide. It is another object of the present invention to provide a multilevel parking garage in which an automobile can be taken in and out of a storage shelf without using a special device such as a gondola mechanism and without using a pallet.

  In order to solve the above problems, a heavy article moving device according to the present invention is a heavy article moving device that lifts and moves a heavy article, and includes a support tool, a frame body, and wheels, and the support tool is a frame body through an elevating device. It is connected to the top surface of the frame and has a plurality of wheels on the bottom surface of the frame. The support is placed under the cargo and lifted by the lifting device to support the cargo. Thus, when supporting the cargo, the support body is arranged so that the load center comes in the surface surrounded by the outermost wheel among the plurality of wheels.

The heavy article moving device of the present invention is used for a cargo having legs and the like and having a gap between the ground and the bottom surface of the cargo. If the lifting / lowering device of the support tool is lifted after being inserted into the lower gap of the cargo with the support tool of the heavy goods moving device of the present invention lowered, the support tool touches the bottom surface of the cargo. When the lifting device is further raised, the support pushes up and lifts the cargo to support the cargo. If the support is raised until the entire cargo is separated from the ground, the cargo can be pulled and moved by the wheels provided in the heavy-weight moving device of the present invention.
The heavy article moving device of the present invention receives the weight of the cargo with a support and supports it with wheels arranged on the bottom surface of the frame. Since the wheels are arranged on the bottom surface of the frame body and the support is provided directly above the frame body, the center of gravity of the cargo is located inside the ring surrounded by the wheels. Accordingly, the weight of the cargo can be reliably received by the wheel, and the heavy object can be stably supported. For this reason, it is not necessary to provide a counterbalance unlike a forklift, and the apparatus can be formed very simply and lightly.

  One heavy load moving device of the present invention may be used alone, or a plurality of heavy load moving devices may be used. For example, when lifting a quadrilateral cargo, a total of four heavy goods moving devices may be used, one at each corner. In this case, if the center of gravity of the entire cargo is located in the surface surrounded by the outermost wheels of the four heavy goods moving devices, the cargo can be stably lifted and supported. In this case as well, the center of the load applied to each heavy load moving device is in the surface surrounded by the wheels of the heavy load moving device. If a plurality of heavy goods moving devices are used according to the shape of the cargo, a large cargo can be lifted without enlarging the heavy goods moving device itself.

  The heavy article moving device of the present invention is conveniently used for jacking up an automobile body, for example, at a repair shop. The vehicle can be lifted by using two heavy goods moving devices that are wider than the body of an automobile and inserting them under the front and rear reinforcing parts to raise the support. Therefore, it is possible to easily move the vehicle, change tires, repair the vehicle body, and the like. Since the heavy goods moving device of the present invention has a simple structure and can be formed relatively lightly, it does not need to be transported to a large lifting device with a fixed installation location, and can be operated easily and safely at any place. it can.

The shape of the support provided in the heavy goods moving device of the present invention may be appropriately selected according to the target cargo. For example, when used for transporting a vehicle, two rods may be arranged horizontally and parallel to each other as a support, and a tire may be mounted on the two rods for support. Moreover, you may form by the board etc. which comprise the gentle curve which protrudes or dents toward a tire. If all tires are lifted by using a plurality of heavy-weight moving devices of this form, the vehicle can be transported without touching the vehicle body at all.
In this case, a part of one side of the frame body is cut out to form a concave shape, and each support tool is arranged perpendicular to one side of the frame body cut out. Can be inserted before and after the tire.

  When lifting the tire with a pair of rods, if there is a concern about the strength of the device and there is a risk that the gap between the supports will widen, after inserting the heavy goods moving device before and after the tire The ends of the support and the ends of the frame body may be temporarily connected with a scissors or the like.

Further, instead of using the heavy load moving device for each individual tire, a heavy load moving device having a width wider than the width of the vehicle body may be used. Two heavy load moving devices are used, and the vehicle body is lifted by inserting the front and rear wheels so that the left and right wheels are sandwiched together and lifting the tires, and transported in the same manner as described above.
If the arm of each heavy load moving device is lowered when it is located at the target location, the arm of the heavy load moving device is separated from the tire, and the vehicle is left at the target location.

For example, the wheels of the heavy article moving device of the present invention may be provided at four corners of the device, or several wheels may be provided on one side. What is necessary is just to provide suitably in a design suitable position.
Further, if the wheels are arranged vertically with respect to the feeding direction, the transfer direction can be restricted to the feeding direction. If the wheel axle is free to rotate, it can be transported in any direction. Depending on the situation, the rotation direction of the wheel shaft may be restricted and released.
For example, it is possible to transport an automobile vehicle in parallel parking using two heavy goods moving devices. In this case, after restricting the wheels in the width direction of the vehicle and pulling out the vehicle in the lateral direction, the wheel of one heavy load moving device is changed in the longitudinal direction of the vehicle and then fixed, and the other weight If the wheel of the object moving device can be freely rotated in the direction, it can be transported while being controlled in the target direction.

  In order to regulate the rotation direction of the wheel, for example, a part of the rotation shaft that connects the wheel and the frame is formed to have a larger diameter than the others and cut into a square shape so that it does not move in the rotation direction of the frame. A rectangular pulley fixed to the upper and lower sides can be fitted on the rotating shaft, and a method of pressing the pulley against the rectangular portion of the rotating shaft from above or a locking method using a key can be used.

The lifting device can be appropriately selected from a hydraulic cylinder, a crank-screw, a pantograph, and the like. Power may be provided or it may be by human power.
Alternatively, an eccentric cam-like support tool that is taller than the upper surface of the frame body may be rotatably fixed inside the frame body, and the cargo may be lifted by rotating the support tool.
The eccentric cam-like supporter may be lifted by using a long bar and manually rotated by the action of a lever, or a hydraulic jack may be provided. Moreover, you may drive with motive power using an electric motor.

Further, the heavy article moving device of the present invention is formed of a right frame part and a left frame part, and a single rod is fixed to the upper surface of each of the right and left frame parts, and a plurality of wheels are provided on the bottom surface. When one end of the right frame part and the left frame part are pivotally supported by a vertical axis and connected, the other end can be opened and closed, and the other end is connected and pulled, and the other ends are pulled to the maximum The right frame part and the left frame part are inserted so as to be sandwiched from the front and rear of the grounded automobile tire, and the right frame part and the left frame part are connected and pulled by the pulling mechanism. Then, the tire may be lifted up by lifting the tire by bringing the rods close to each other.
The support is preferably formed with a roller or the like in order to reduce friction with the tire. In addition, for example, another iron pipe having an inner diameter larger than the outer diameter of the iron rod may be freely and loosely covered on a strong iron rod, and the friction may be eliminated by allowing autonomous rotation. Friction may be reduced by loosely covering a cloth or plastic tube.

The pulling mechanism may be, for example, a chain connected to one support or frame and a sprocket on the other, a bolt on one side of the frame, a nut on the other, and a head on one frame. It is also possible to bring the frame parts closer to a fixed position by rotating the fixed bolt to the other frame body with a nut that can move laterally within a certain range and is freely rotatable. good.
Because a strong force is required to pull the frame parts withstanding the weight of the tire of an automobile vehicle, for example, when using a chain, even if a long rod is inserted into a take-up device such as a sprocket, It may be good or the pressure may be increased by hydraulic pressure. A motor may be used.

A ratchet or the like that allows rotation only in a desired rotation direction may be incorporated in the sprocket or the like of the attracting device. Incorporating a ratchet makes it very easy to move the lever rod, and if you unlock the ratchet for a short time, the chain can be loosened slowly, and it will fall abruptly when you drop the car Can be prevented.
If the chain or the like is pulled to a fixed position, it may be fixed as it is. However, for the sake of convenience, for example, a chain may be inserted to prevent the chain from loosening.

  Insert the heavy load moving device of the main body so as to be sandwiched between the front and back of the tire, pull the chain, etc., and bring the supports closer to each other to lift the tire. If this is mounted on the front, rear, left and right tires, the vehicle can be lifted and transported without touching the vehicle body at all. In the heavy-weight moving device of this form, the opening of the support and the frame can be made very large, so that it can be easily inserted into the tire and work efficiency can be improved. You may make it lift a left-right wheel at once using the heavy goods moving apparatus of the length larger than the width | variety of a vehicle.

  On the other hand, the heavy goods moving cart of the present invention can also be formed by mounting the heavy goods moving device of the present invention on a cart having a surface with a sufficient area for placing cargo so that it can be drawn out and drawn in the horizontal direction. A recess is formed on a part of the upper surface of the carriage to form a moving device storage groove, and the heavy article moving device of the present invention is incorporated by fixing the wheel in the feeding direction so that the wheel can run and draw out the bottom of the storage groove. To do. One or more heavy object moving devices may be incorporated. The heavy article moving device is preferably drawn out and drawn in the width direction of the heavy article moving carriage.

  Cargo by pulling out the heavy goods moving device from the heavy goods moving carriage of the present invention, inserting the heavy goods moving device into the gap under the cargo with legs or the cargo mounted on the legs, and raising the support. After lifting, the heavy goods moving device together with the cargo is drawn on the cart and the support is lowered, so that the cargo is left on the cart. Since the weight is always supported by many wheels on the bottom surface of the heavy-duty moving device even during the feeding and pulling-in, the balance is not lost or unstable even when the heavy load is placed.

The heavy load moving device can be pulled out and pulled in by human power, but a pinion is installed on the side of the heavy load moving device, a rack is installed on the side of the heavy load moving device storage part on the carriage, and the pinion is rotated by a motor or the like. By doing so, it may be possible to perform withdrawal and withdrawal.
Moreover, you may carry out by connecting a heavy article moving apparatus and a trolley | bogie through the pantograph like a magic hand, and expanding / contracting the pantograph.

When the cargo is on a high floor surface, it is necessary to provide a mechanism that matches the height of the wheel support surface on the heavy-duty moving carriage with the height of the floor surface for loading and unloading the cargo. Therefore, when the heavy load moving carriage is equipped with a lifting device, the heavy load moving cart is raised by the lifting device, and the height of the wheel support surface on which the heavy load moving device travels matches the height of the floor on which the cargo is placed. Good. Thereafter, the cargo is lifted by feeding the heavy goods moving device into the gap under the cargo and raising the lifting device of the heavy goods moving device. Thereafter, the heavy article moving device may be pulled on the heavy article moving carriage.
In order to make the height of the wheel support surface on the heavy-duty moving carriage coincide with the height of the floor surface for loading and unloading the cargo, it may be by visual measurement, or by a sensor such as a sensor bar, an infrared sensor, or an ultrasonic sensor.

When cargo or the like is in contact with the ground, there is a gap between the ground and the height of the wheel support surface of the carriage. Therefore, the above operation may be performed after placing a plate or sleepers in the gap under the cargo to adjust the height.
However, since it is cumbersome to bite a plate or the like, it is desirable to provide a mechanism that eliminates the difference in height between the ground and the wheel support surface of the heavy-duty moving carriage. Therefore, the heavy-duty moving carriage according to the present invention is preferably provided with a legged wheel in the heavy-duty moving apparatus, and a conventional wheel on the carriage and a grounded wheel on the ground. The legs of the wheels running on the ground are retractable, and the legs are stored on the carriage and run on the carriage wheels with a low height, but when the heavy goods moving device is extended and removed from the carriage, the legs To move to the wheel for running on the ground. The leg should be equipped with a locking device to prevent the leg from falling on the ground.
Moreover, the wheel for the wheel support surface of the heavy-duty moving carriage may be installed on the side surface of the leg of the ground traveling wheel, and the wheel support surface may be traveled by the side wheel when the leg is tilted.

It is convenient if the heavy goods moving carriage of the present invention is provided with two heavy goods moving devices. For example, a heavy-duty moving carriage equipped with two heavy-duty moving devices can lift the vehicle by holding the front and rear wheels of the automobile. If the upper structure is lowered and the cargo is allowed to stand on the heavy load moving carriage after being pulled in on the heavy load moving carriage, more stability can be obtained than it is supported on the heavy load moving apparatus.
In the heavy-duty moving carriage equipped with two heavy-weight moving devices, the position of the moving device storage groove can be adjusted so that the position where one or both of the heavy-weight moving devices is pulled in is matched with the supporting position of the heavy load. If so, it can handle cargo of various lengths.
Needless to say, when targeting a vehicle having three or more wheel axles, it is preferable to provide three or more heavy article moving devices.

In particular, when an automobile vehicle is handled with the heavy-duty moving carriage of the present invention, it is preferable to use a heavy-duty moving carriage provided with a heavy-weight moving apparatus provided with a support made of a pair of pipes that can grip a tire. The support has a length comparable to the width of the vehicle, and a lock device may be provided at one end of the support that is far from the carriage.
When transporting an automobile vehicle at a fixed position onto a heavy-duty moving carriage, insert a heavy-duty moving device in front of and behind the tire, and connect a pair of arms with a locking device installed at the far end of the heavy-weight moving device. Then, after temporarily reinforcing, the heavy load moving device is lifted until the tire is separated from the floor surface, and the arm of the heavy load moving device is transferred onto the heavy load moving carriage.
After pulling the heavy goods moving device with the tires on top of the heavy goods moving carriage, lower the arm of each heavy goods moving equipment, the arm of the heavy goods moving device will be separated from the tire, and it will be left on the floor of the heavy goods moving cart. The You may carry as it is, supporting on a heavy article moving apparatus, without leaving still on the floor surface of a heavy article moving trolley | bogie.

This heavy-duty moving carriage can be used for removing illegally parked vehicles and moving accident vehicles, and for loading and unloading automobile vehicles on railway wagons and vehicle carriers.
Conventionally, even if an automobile is loaded on a freight car, there is only a method of self-propelled on an inclined plate from the rear part of the freight car, for example. Even if you try to use a pallet to load from the side of the freight car, it is difficult to support it with a forklift because of its weight.
By using this heavy goods moving carriage, it is possible to quickly load and unload automobile vehicles and heavy cargo on the wagons. It can also be used for vehicle carriers and the like, and since there is no need for a self-propelled passage, it can be loaded more densely than before.
Freight cars, transport ships, etc. need only have a flat floor and storage shelves, and no other equipment is required.

  For example, when you want to unload a car from a railway freight car, place a heavy goods moving carriage with a lifting function on the freight car, insert a heavy goods moving device so that the front and rear tires are sandwiched, and use a lock device provided at one end of the far When the pair of arms are temporarily fixed and reinforced to raise the support, the automobile vehicle moves away from the floor. Thereafter, when the heavy article moving device on which the automobile vehicle is mounted is drawn onto the heavy article moving carriage, the automobile vehicle is transferred onto the heavy article moving carriage. The support surface component may be lowered and lowered onto the heavy-duty moving carriage, or may be transported to a target location while being supported by the heavy-weight moving device.

When the target location is reached, the heavy-duty moving device on which the automobile vehicle is mounted is pulled out from the heavy-duty moving carriage, and the support structure is lowered, so that the automobile vehicle is placed on the floor surface. When loading, the reverse operation is sufficient.
Since the wheel base differs depending on the vehicle type, it is desirable to be able to cope with various vehicle types by changing the positions of the two heavy goods moving devices.
If the heavy-duty moving carriage using the heavy-duty moving apparatus of the present invention is used, it is possible to quickly load and unload automobile vehicles. In addition, no special equipment is required for freight cars and the like, and mass transportation of automobile vehicles by rail is enabled.
Of course, it is also possible to change the shape of the heavy goods moving device and use it for loading and unloading cargo other than automobile vehicles.

As described above, by using the heavy-duty moving carriage of the present invention, it is possible to handle a heavy vehicle or a heavy cargo that is difficult to handle with a forklift. In addition, stability is obtained because the weight of the cargo is always supported by wheels.
The heavy goods moving cart of the present invention may be towed by human power or another vehicle, or the heavy goods moving cart itself may be provided with a traveling mechanism and carried by itself.

  In conventional forklifts, since they are supported by cantilever beams, it was necessary to overhang the vehicle body in the opposite direction to counter the weight of the cargo or fork, or it was necessary to make the vehicle body heavy or to have a counterbalance. The heavy-duty moving carriage of the present invention does not need to be unnecessarily heavy, nor does it need to force parts such as a machine part to be forced out of the carriage. Since the heavy-duty moving carriage itself can be made relatively light, energy can be saved even if it is designed to run on its own.

  In addition, the conventional forklift has been transported while confirming the front of the driver over the previous cargo. However, since the heavy-duty mobile carriage of the present invention can be installed at the end of the carriage, the truck can be loaded and unloaded. If this is performed in the lateral direction, the driver's seat can be installed so as to face the traveling direction, and cargo can be transported while obtaining good visibility. The driver's seat may be rotated so that it is directed toward the top of the cart during loading / unloading, and may be directed forward when the loading operation is completed and the heavy-duty moving cart is driven.

  The heavy-duty moving carriage of the present invention may be taken in and out in the vertical direction as in a conventional forklift. If a heavy-duty cart is equipped with a self-propelled mechanism, the same work as a conventional forklift can be performed. In addition, cargo that is difficult to handle with conventional forklifts and that has a large depth and exceeds the limit of the length of the fork, or that has a risk of overturning the main body of the forklift with a cantilevered fork due to its weight. But you can handle it.

A transportable multi-level parking garage can also be configured by mounting a heavy load moving carriage that can relatively change the position of the two heavy load moving devices on a stacker crane. The three-dimensional parking lot of the present invention includes a storage shelf and a stacker crane, and the heavy-duty moving carriage of the present invention is mounted on the stacker crane. The front and rear wheels of the parked vehicle parked at the carry-in entrance are each lifted by the heavy load moving device and pulled into the heavy load moving carriage on the stacker crane, moved to the side of the target storage shelf by the stacker crane, and then moved by the heavy load moving device. Extend the parked vehicle to the storage shelf and leave it stationary.
The transport type multi-story parking lot using the stacker crane equipped with the heavy goods moving carriage of the present invention does not require a special device other than the stacker crane, and the storage shelf may be a simple floor surface. For this reason, the parking lot facility itself can be configured relatively inexpensively.

Gondola type multistory parking lots require a large strength and driving force to support the weight because all the weights of the gondola and the accommodated vehicles are applied to the rotating shaft. In order to store the storage rack, it is necessary to perform complicated work to change the storage shelf.
Since the transfer type multi-story parking lot using the heavy-duty moving carriage of the present invention only needs to handle one automobile vehicle, it does not require so much strength and power. Moreover, since only one vehicle is moved in and out, it can be taken in and out quickly.

  The floor surface of the multi-story parking lot may be flat as described above.For example, the storage shelves of the multi-story parking lot may be placed at a location corresponding to, for example, the front and rear wheel tires on either the right or left side of the wheel. A relatively shallow dent for fitting an individual tire or a shallow groove for fitting a front or rear tire may be provided at a location corresponding to the tire. In this way, even if there is an earthquake, for example, the risk of being displaced or falling from the storage shelf is reduced.

  Needless to say, it can be used not only in multi-level parking lots, but also in multi-level warehouses that can handle cargo on a pallet with legs, or with different distances between installed legs or heavy cargo.

  With the heavy goods moving device of the present invention, heavy goods or heavy goods are always carried while being supported by the lower wheels, so that long and heavy goods that have been difficult to carry with conventional forklifts can be stabilized. Can be transported. Also, the vehicle can be transported without touching the vehicle body by gripping and lifting the tire.

If a heavy-duty moving carriage equipped with a plurality of heavy-duty moving apparatuses of the present invention is used, a heavy cargo that has conventionally had to be lifted up by a crane or the like and loaded on a loading platform or the like can be easily transported. be able to.
The three-dimensional parking lot using the heavy-duty moving carriage of the present invention can quickly put in and out an automobile vehicle without requiring a special device in the storage shelf.

  Hereinafter, the heavy article moving device of the present invention will be described in detail.

FIG. 1 is a perspective view of a heavy article moving device according to one embodiment of the present invention. The heavy article moving device of the present invention includes a support 1 that is a cargo support section that can be moved up and down, a frame 2 that supports the support 1 and can be moved up and down when desired, and a caster 3 below the frame 2. Consists of.
A rotatable caster 3 is fixed to both sides of the frame body 2, and the support 1 is installed on the frame body 2 via a hydraulic cylinder 4 so as to freely move up and down. Each hydraulic cylinder 4 is connected by a hydraulic tube (not shown).
By moving the handle bar 5 up and down, the nearest hydraulic cylinder 4 is raised and the other hydraulic cylinder 4 is raised through the hydraulic tube to lift the support 1.
After inserting the heavy load moving device into the gap under the cargo, if the support 1 of the heavy load moving device is raised by the above operation, one end of the cargo is stably lifted. The entire cargo can be lifted by inserting a plurality of heavy goods moving devices into the ends of the cargo and raising the respective supporting tools. What is necessary is just to convey the lifted cargo to a desired place with the caster 3 for driving | running | working. Of course, if it is a small cargo, you may carry with one heavy goods moving apparatus.

When the cargo is lifted and transported, the caster 3 is always in contact with the ground. Therefore, if the length of the heavy goods moving device is appropriately set according to the size of the cargo, a heavy cargo or a wide cargo can be stably stabilized. Can be lifted and transported.
When transported to a desired place, a hydraulic release valve (not shown) is opened to release the hydraulic pressure, and the support 1 is lowered together with the cargo to ground the cargo. Further, when the support tool 1 is lowered and the support tool is separated from the cargo, the heavy article moving device may be pulled out from the gap under the cargo.

The heavy article moving device according to the present embodiment can be appropriately changed in shape according to the cargo to be transported. FIG. 2 is a perspective view of a heavy article moving device formed for gripping a tire and carrying the vehicle. The frame body 2 and the upper structure 6 are coupled to each other through lifting / lowering devices 7 provided at both ends of the heavy load moving device. The elevating device 7 is composed of a pair of connecting shafts arranged in a letter C, and the upper end of the connecting shaft is pivotally supported by the upper structure 6, and the lower end of the screw rod 8 is arranged on the frame 2. Is engaged. A crank 9 is connected to one end of the screw rod 8, and by rotating the crank 9, the screw rod 8 rotates, the lower end of the lifting device 7 is opened and closed, and the upper structure 6 is changed by changing the tangent of the connecting shaft. Is going up and down. The lifting device 7 is provided at both ends of the frame body 2, and the lifting device 7 that is not connected to the crank 9 moves up and down in conjunction with the rotation transmission shaft 10 provided on the back surface of the frame body 2.
When the upper structure 6 and the frame 2 are inserted below the tire, the upper structure 6 and the frame body 2 have an opening that is long enough to be inserted before and after the tire.
In the upper structure 6, two pipes 11 are arranged in parallel. When the upper structure 6 is raised, the pipe 11 rises together with the upper structure 6, and the pipe 11 contacts the tire to hold the tire. The pipe 11 has an appropriate interval smaller than the diameter of the tire, and when the tire comes in contact with the tire, the tire is sandwiched with a certain margin, and when it rises, the tire can be held without coming off the tire. Yes.

If the crank 9 is rotated with the opening portion facing forward after inserting the heavy-weight moving device of the main body so as to sandwich the tire, the upper structure 6 rises and the pipe 11 contacts the front and rear of the tire. If the crank 9 is further rotated to raise the upper structure 6, the tire is lifted.
If four heavy load moving devices are used and the front, rear, left and right wheels are lifted, the vehicle can be moved without contacting the vehicle body.

FIG. 3 is a perspective view of the heavy article moving device according to another embodiment of the present embodiment.
The frame body 2 is divided into a right frame part 12 and a left frame part 13, and one pipe 11 is directly connected to each of them. One end of each of the left and right frame parts 12 and 13 is connected by a hinge or the like, and the other end can be separated, close, or contacted. A chain 14 for bringing the left and right parts of the frame part into close contact is provided. The right frame part 12 is provided.

The left frame part 13 is provided with a rotating sprocket 15 for feeding the other end of the chain 14. A ratchet is incorporated in the rotating sprocket 15. After one end of the chain 14 is inserted under the rotating sprocket 15 and bitten, the handle 14 is moved up and down to retract the chain 14. As a result, the distance between the right frame part 12 and the left frame part 13 is reduced, the distance between the pipes 11 is reduced, and the tire is lifted up and supported by the pipe 11. After the tire is separated from the ground and supported by the pipe 11, the tire can be freely moved by the wheels 17 provided on the right frame part 12 and the left frame part 13.
The ratchet provided on the rotary sprocket 15 applies a force only in the closing direction, and does not cause a loosening force when the handle bar 16 is moved to the opposite side of the closing direction.

When the front sides of the left and right frame parts 12 and 13 are in contact with each other, it is only necessary to reinforce them by inserting the flanges 19 into the side hole 18 on both sides so that the tire is not dropped even if the chain is removed.
Even when the heavy goods moving device is inserted between the front and rear of the grounded tire, or when the tire is held and lifted, the wheel 17 below the heavy goods moving device is always in contact with the ground, so that it is possible to always ensure the storage.
A direction regulating device 20 is provided on a part of the rotational shaft of the wheel, and the rotational direction can be regulated as necessary.
As the distance between the pipes 11 is reduced and the tire is lifted, friction is generated between the pipes 11 and the pipe 11 can be rotated freely. Friction may be eliminated by loosely covering a flexible cover such as cloth or leather.
The vehicle can be moved by using four heavy load moving devices of this embodiment and lifting the four wheels of the vehicle.

The heavy article moving device of the present invention can be mounted on a carriage to form a heavy article moving carriage. FIG. 4 is a perspective view of a heavy goods moving carriage provided with two heavy goods moving devices. In the figure, one drawing of the heavy article moving device is omitted.
