Description

Technical Field

[0001] This application relates to the technical field of transfer devices, and in particular to a load platform for transportation. Background Art

[0002] Currently, during the process of goods transportation, loading, unloading, and transferring goods are generally carried out inside a container. Most of the current load platforms inside containers are directly paved with diamond plates. Goods are placed on the diamond plates, and then the goods are carried by hand or assisted by transportation tools (such as forklifts, etc.).

[0003] Regarding the above related technologies, since the goods are in direct contact with the diamond plates, when manually carrying the goods, the goods will have sliding friction with the diamond plates, and the work done by the staff to overcome the frictional resistance is relatively large; while if a forklift is used for carrying, the staff needs to move the forklift back and forth, which is rather cumbersome, and it is not easy to adjust the angle of the forklift. The labor intensity of the entire working process is relatively large, and the operation efficiency is low, so it needs to be improved. Utility Model Content

[0004] In order to facilitate the staff to carry goods, this application provides a load platform for transportation.

[0005] The load platform for transportation provided by this application adopts the following technical solutions:

[0006] A load platform for transportation includes a chassis, a support plate, a mounting seat, a cover plate, a jacking assembly, and a roller assembly. The support plate is connected to the chassis and is used to support goods; the mounting seat is connected to the chassis, the cover plate is connected to the chassis, and a receiving cavity is formed between the cover plate and the chassis. The jacking assembly is arranged in the receiving cavity;

[0007] The roller assembly is arranged above the jacking assembly and is vertically movable. The jacking assembly is used to control the up and down movement of the roller assembly; several groups of the roller assemblies are distributed at intervals along the length direction of the cover plate, and through holes for the roller assemblies to pass through are formed on the cover plate.

[0008] By adopting the above technical solutions, when loading goods, first place the packaged goods on the support plate of this load platform, then turn on the on-vehicle air compressor, and use the jacking assembly to control the roller assembly to rise, thereby driving the goods to a position higher than the horizontal plane where the support plate is located. Then the staff push the goods to the designated position, and finally turn off the on-vehicle air compressor. The principle of the entire operation process is to use rolling friction instead of sliding friction to reduce the friction between the goods and the load platform, achieving the effect of being able to push the goods freely by hand.

[0009] When unloading is required, turn on the vehicle-mounted air compressor, wait for the roller assembly to lift the goods to a position higher than the plane where the support plate is located, and then push the goods onto the vehicle-mounted lifting tailboard; finally, lower the vehicle-mounted lifting tailboard and use a forklift to push the goods away.

[0010] When transfer between vehicles is required, dock the rear ends of the two vehicles that need to be transferred, turn on the on-board air compressor, wait for the roller assembly to lift the cargo to a position higher than the plane of the support plate, then push the cargo to the designated position on the other vehicle, and finally turn off the on-board air compressor.

[0011] Preferably, the lifting component is a lifting airbag.

[0012] By adopting the above technical solution, when working, the vehicle-mounted air compressor is turned on, and the lifting airbag expands under the action of air pressure, thereby lifting the roller assembly.

[0013] Preferably, the lifting assembly includes a lifting plate and a driving member, the lifting plate is located below each of the roller assemblies and is arranged to be lifted, and the driving member is connected to the lifting plate and is used to control the lifting plate to move up and down.

[0014] By adopting the above technical solution, the driving member can control the lifting plate to move up and down, and the movement of the lifting plate can drive the roller assembly to rise synchronously, so that the roller assembly can lift the goods. The driving member can be a linear power unit such as a cylinder, a hydraulic cylinder or an electric mechanical structure.

[0015] Preferably, the roller assembly comprises a roller shaft and a rolling wheel, both ends of the roller shaft are connected to the rolling wheels, the two rolling wheels are arranged at an interval, and both can rotate freely around the roller shaft.

[0016] By adopting the above technical solution, when the goods are being transported, the rolling wheel can rotate relative to the roller shaft (the rolling wheel rotates, and the roller shaft does not rotate), thereby achieving rolling friction.

[0017] Preferably, it also includes a cargo baffle, the support plate is provided with a clearance groove, the cargo baffle is rotatably connected to the support plate and is located in the clearance groove, the cargo baffle is used to block the cargo on the support plate; wherein, a plurality of cargo baffles are provided, and each of the cargo baffles is spaced apart along the length direction and the width direction of the support plate.

[0018] By adopting the above technical solution, after the staff adjusts the position of the goods relative to the load platform, the staff can rotate the cargo baffle so that the cargo baffle forms a certain angle with the support plate. The cargo baffle can have a certain blocking and limiting effect on the goods, thereby reducing the possibility of the goods sliding during transportation. When in use, the cargo baffle is flipped out of the clearance slot, and then put back into the clearance slot after use.

[0019] Preferably, a groove is formed in the cargo retaining plate, so that a first column and a second column are formed at one end of the cargo retaining plate away from its hinge. The groove is located between the first column and the second column, and the length of the first column is shorter than that of the second column; when the cargo retaining plate is located in the groove, the first column is close to the notch of the groove.

[0020] By adopting the above technical solution, the presence of the groove can facilitate the staff's fingers to reach in, and then control the rotation of the cargo retaining plate.

[0021] Preferably, it further includes a bracket, the bracket is located above the lifting assembly, the roller assembly is arranged between the bracket and the cover plate and is connected to the bracket, and the roller assemblies are distributed at intervals along the length direction of the bracket.

[0022] By adopting the above technical solution, as a carrier, the bracket can support the roller assemblies, so as to drive the synchronous lifting of the roller assemblies.

[0023] Preferably, the support plate is made of aluminum alloy.

[0024] By adopting the above technical solution, the aluminum alloy support plate is a self-designed profile die-cast by an aluminum alloy forming die. Its characteristics are that the density is smaller than that of iron, and the weight is much smaller than that of iron products under the same volume, and it can ensure mechanical strength. Because it is die-cast by a die, the size is standard and the surface is smooth. At the same time, due to the material, the aluminum alloy support plate has good corrosion resistance without other surface treatments.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] (1) By setting the lifting assembly and the roller assembly, when it is necessary to carry goods, the lifting assembly can be used to control the roller assembly to rise, so as to drive the goods to a position higher than the horizontal plane where the support plate is located, and then the staff can push the goods to the designated position. By changing sliding friction into rolling friction, the friction between the goods and the load platform is reduced, thereby reducing the labor intensity of the personnel.

[0027] (2) By setting the cargo retaining plate, the cargo retaining plate can play a role in separating and limiting the goods, reducing the possibility of the goods shifting during transportation.

[0028] (3) By using aluminum alloy to make the support plate, the aluminum alloy has the characteristics of light weight and high strength, making the support plate light and durable and not easily damaged. Description of the Drawings

Without conflict, those skilled in the art can combine and combine the different embodiments or examples represented in the present application and the features of different embodiments or examples.

[0039] An embodiment of the present application discloses a load platform for transportation. Referring to Figure 1 and Figure 2 , the load platform includes a chassis 1, a support plate 2, a mounting seat 3, a cover plate 4, a lifting assembly 5, and a roller assembly 6. The chassis 1 serves as a support carrier and is welded by channel steel, angle iron, and sheet metal bending parts; the chassis 1 mainly includes girders, cross beams, side groups, and various bending parts, and the above-mentioned various materials are welded according to size requirements.

[0040] The support plate 2 is fixedly installed on the chassis 1 and is used to support goods. In this embodiment, the support plate 2 is made of aluminum alloy material. The aluminum alloy support plate 2 is a self-designed profile die-cast by an aluminum alloy forming die. Its characteristics are that the density is smaller than that of iron. Under the same volume, the weight is much smaller than that of iron products, and it can ensure mechanical strength. Because it is die-cast by a die, the size is standard and the surface is smooth. At the same time, due to the material, the aluminum alloy support plate 2 has good corrosion resistance without other surface treatments, which can extend the service life of the support plate 2.

[0041] The mounting seat 3 is connected to the chassis 1. The cover plate 4 is detachably connected to the mounting seat 3 by a clamping method, and at the same time, the cover plate 4 is fixed to the chassis 1 by bolts or screws. An accommodation cavity 8 is formed between the cover plate 4 and the mounting seat 3, and the lifting assembly 5 is installed in the accommodation cavity 8. The roller assembly 6 is located above the lifting assembly 5 and is arranged to be liftable. The lifting assembly 5 is used to control the up and down movement of the roller assembly 6. Among them, several groups of roller assemblies 6 are spaced along the length direction of the cover plate 4, and through holes 7 for the roller assemblies 6 to pass through are formed on the cover plate 4.

[0042] Specifically, the lifting assembly 5 is a lifting airbag. A bracket 9 is also installed on the chassis 1. The bracket 9 is located in the accommodation cavity 8 and is above the lifting airbag. The bottom of the bracket 9 is in close contact with the upper surface of the lifting airbag. The roller assembly 6 is installed on the bracket 9 and is between the bracket 9 and the cover plate 4. Each roller assembly 6 is spaced along the length direction of the bracket 9. In some embodiments, the lifting assembly 5 can also be a lifting plate and a driving member. The lifting plate is arranged to be liftable in the mounting seat 3, and the bracket 9 is placed on the lifting plate; the driving member is connected to the lifting plate and is used to control the up and down movement of the lifting plate. The driving member can be, but is not limited to, a linear power unit such as a cylinder, an oil cylinder, or an electric push rod.

[0043] Combined with Figure 3, the roller assembly 6 includes a roller shaft 61 and rolling wheels 62. The rolling shaft is installed on the bracket 9, and both ends are rotatably connected to the rolling wheels 62. The two rolling wheels 62 are arranged at intervals, and both can rotate freely around the roller shaft 61. The rolling wheels 62 can be selected from bearing rollers or universal balls, etc. The through holes 7 on the cover plate 4 are used for the rolling wheels 62 to pass through.

[0044] In addition, in combination with Figure 4 , a baffle 10 is also rotatably connected to the support plate 2. A relief groove 11 is formed on the support plate 2. The baffle 10 is located in the relief groove 11 and is used to partition the goods on the support plate 2. Among them, a plurality of baffles 10 are provided, and the baffles 10 are distributed at intervals along the length and width directions of the support plate 2. When in use, the baffle 10 is flipped out from the relief groove 11, and after use, the baffle 10 is retracted into the relief groove 11 again.

[0045] When loading goods, first place the packaged goods on the support plate 2 of the load platform, and then turn on the on-vehicle air compressor. The lifting airbag expands under the action of air pressure to control the roller assembly 6 to rise, thereby driving the goods to a position higher than the horizontal plane where the support plate 2 is located. Then the staff pushes the goods to the designated position, and installs the baffle 10. Finally, turn off the on-vehicle air compressor. The principle of the whole operation process is to use rolling friction instead of sliding friction to reduce the friction between the goods and the load platform, achieving the effect of being able to push the goods manually at will.

[0046] When unloading goods, turn on the on-vehicle air compressor. When the roller assembly 6 raises the goods to a position higher than the plane where the support plate 2 is located, at the same time, lower the baffle 10, and then push the goods onto the on-vehicle lifting tailboard; finally, lower the on-vehicle lifting tailboard and push the goods away with a forklift.

[0047] When transferring goods between vehicles, dock the tails of the two vehicles that need to transfer, turn on the on-vehicle air compressor. When the roller assembly 6 raises the goods to a position higher than the plane where the support plate 2 is located, lower the baffle 10; then push the goods to the designated position on the other vehicle, install the baffle 10 on the other load platform, and finally turn off the on-vehicle air compressor.

[0048] As shown in the figure, the baffle 10 is also provided with a groove 12, so that a first post 13 and a second post 14 are formed at one end of the baffle 10 away from its hinge. The groove 12 is located between the first post 13 and the second post 14, and the length of the first post 13 is shorter than that of the second post 14. When the baffle 10 is located in the groove 12, the first post 13 is close to the notch of the groove 12. The existence of the groove 12 can facilitate the staff to insert their fingers and then control the rotation of the baffle 10.

[0049] The implementation principle of a load platform for transportation in an embodiment of the present application is as follows: When loading goods, first place the packaged goods on the support plate 2 of the load platform, then turn on the vehicle-mounted air compressor, and use the lifting component 5 to control the roller component 6 to rise, thereby driving the goods to a position higher than the horizontal plane where the support plate 2 is located. Then the staff push the goods to the designated position, and finally turn off the vehicle-mounted air compressor. The principle of the entire operation process is to use rolling friction instead of sliding friction to reduce the friction between the goods and the load platform, achieving the effect of being able to push the goods manually at will.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
