Description

Technical Field

[0001] The utility model relates to the technical field of platform vehicles, in particular to a transportation loading and unloading platform vehicle. Background Art

[0002] Platform trucks are mechanical equipment used for short-distance cargo transportation. They are convenient for picking up and placing goods. They are mainly used for packaging, stacking, handling and transporting goods and products as unit loads. Platform trucks are divided into scissor-type lifting platforms, aluminum alloy lifting platform trucks, cylinder lifting platforms, articulated arm lifting platforms, fixed lifting platforms, mobile lifting platforms, stage lifting platform trucks, etc. They have the characteristics of stable structure, flexible movement, smooth lifting, easy operation and large load capacity.

[0003] At present, the existing loading and unloading platform vehicles are divided into those with guard plates and those without guard plates. The platform vehicles with guard plates have certain limitations on the size requirements of the goods during loading and unloading because the guard plates are fixed. The platform vehicles without guard plates have no requirements on the size of the goods, but the goods are very likely to fall due to vibration during transportation. At present, there is no platform vehicle that can remove or raise the guard plates according to the size of the goods. In addition, when the existing transport loading and unloading platform vehicles are moved to the side of the conveyor for loading and unloading during use, they are very likely to be displaced and deviated due to the lack of a connecting structure, resulting in a gap between the platform vehicle and one side of the conveyor, which in turn affects the loading and unloading of the goods. Moreover, if the gap between the platform vehicle and the conveyor is too large, there will be certain risks for the staff when loading and unloading, and it is relatively unstable to use. For this reason, we propose a transport loading and unloading platform vehicle. Utility Model Content

A pull groove 20 is provided, and an insertion rod 21 is slidably installed inside the pull groove 20, and a sliding plate 22 is fixedly installed on the outside of the insertion rod 21. A spring 23 is installed on the outside of the insertion rod 21 and on one side of the sliding plate 22. One end of the insertion rod 21 extends to the outside of the cargo platform 5 and a pull plate 24 is fixedly installed. A plurality of sockets 25 are opened inside the side guard plate 17, and one end of the insertion rod 21 extends to the inside of the through groove 16 and cooperates with the sockets 25. There are three side guard plates 17, and the three side guard plates 17 are respectively located on the cargo platform 5 and both sides and on the side away from the overlapping groove 6. One side of the overlapping groove 6 is the loading and unloading side, which is convenient for loading and unloading goods.

[0022] A cross lifting mechanism 2 is provided on the top of the base 1, a moving wheel is provided on the bottom of the base 1, and a push-pull handle is provided on one side of the base 1, wherein the moving wheel has a brake, and a control button is provided on the push-pull handle. The cross lifting mechanism 2 includes a cross rod, a driving cylinder slider and a slide. When in use, the driving cylinder is turned on to push one cross rod to rise while driving the other cross rod to slide, thereby allowing the top plate 3 and the cargo platform 5 to be raised and lowered.

[0023] A lap groove 6 is provided at the bottom of one side of the cargo platform 5, and a first anti-skid plate 7 is fixedly installed on the top inside the lap groove 6. A drive box 8 is fixedly installed on one side of the top plate 3. A slide groove 9 is provided inside the drive box 8, and a device motor 10 is fixedly installed in the middle of the slide groove 9. A screw rod 11 is fixedly installed on the output end of the device motor 10, and a sleeve block 12 is threadedly installed on the outer side of the screw rod 11.

[0024] In summary, when the transport loading and unloading platform vehicle is in use, when it is necessary to load and unload smaller-sized goods and to limit the side guard plates 17, it is only necessary to pull the pull plate 24 from the side to drive the insertion rod 21 to move sideways so that it can be pulled out of the insertion hole 25 to release the limit of the side guard plates 17. Then, it is only necessary to push the side guard plates 17 up to the applicable height and release the pull plate 24. The spring 23 rebounds and pushes the sliding plate 22 to drive the insertion rod 21 to reset and insert it into the insertion hole 25 to fix the side guard plates 17 at the specified height. Then, the cross lifting mechanism 2 is controlled by the control button. After adjusting the cargo platform 5 to a height higher than the conveyor, the platform vehicle body can be moved to the unloading place of the conveyor by pushing and pulling the handle, and then the height of the cargo platform 5 can be slightly lowered by the cross-lifting mechanism 2 so that the cargo platform 5 can be overlapped on the conveyor through the overlapping groove 6. Finally, the device motor 10 is turned on by the control button to drive the two screw rods 11 to rotate. The screw rod 11 drives the two sleeves 12 to move through the thread, and the connecting rod 13 can push the abutment plate 14 and the second anti-skid plate 15 upward to abut the bottom of the conveyor, and then the platform vehicle can be fixed to one side of the conveyor.
