Description

Technical Field

[0001] The utility model relates to the technical field of unloading equipment, in particular to an unloading device for highway transportation. Background Art

[0002] Road transport is a mode of transporting goods and personnel. It is the transportation of people and goods by vehicles on roads. Road transport is also relatively flexible in terms of time. Vehicles can be dispatched and loaded at any time, and the connection time between each link is short. Compared with railway, water and air transport, road transport requires simpler fixed facilities.

[0003] When transporting goods by road, after the truck arrives at the delivery location, the goods need to be unloaded manually or large items need to be unloaded through an unloading device. A road transport unloading device is a device that helps the truck unload goods and can unload the goods quickly, efficiently and safely.

[0004] However, some delivery locations do not have unloading platforms. When unloading some bulk goods, a forklift is needed to lift the pallet. The unloader stands on the pallet, and the forklift lifts the pallet and the unloader to a higher place. Only then can the unloader unload the goods from the high place of the truck. However, when the forklift lifts the pallet, the pallet may not be placed in the center of the fork teeth. During the rising process, the pallet may tip over, causing the unloader to fall from above and injure the unloader. For this reason, we provide a road transport unloading device to solve the above problems. Utility Model Content

The anti-fall mechanism 8 includes a slide seat 801, one side of the slide seat 801 is fixedly connected to the upper surface of the unloading platform 2, the inner side of the slide seat 801 is slidably connected with a blocking rod 802, the outer surface of the blocking rod 802 is fixedly connected with a push piece 803, one side of the push piece 803 is movably contacted with a spring 804, and the other end of the spring 804 is movably contacted with the inner wall of the slide seat 801, and the slide seat 801 can maintain the stability of the blocking rod 802 when sliding, and the push piece 803 can receive power for resetting the blocking rod 802, and the push piece 803 is pushed to move its position by the spring 804, so as to provide power for resetting the blocking rod 802, the outer surface of the slide seat 801 is fixedly connected with a support plate 805, the outer surface of the blocking rod 802 is fixedly connected with a positioning block 806, and the end of the blocking rod 802 located outside the slide seat 801 is fixedly connected with a pull ring 807, which is connected to the support plate 80 5, the pull ring 807 is used to pull the stopper 802 to move the position, and the pull ring 807 pulls the pull rod to move the position while driving the positioning block 806 to move at the same time, and the push piece 803 compresses the spring 804, and the stopper 802 is rotated when the positioning block 806 moves to be parallel to the support plate 805, and the positioning block 806 contacts one end of the support plate 805, which can release the contact between the stopper 802 and the through hole 809, and the unloading platform 2 can move up and down. The outer surface of the guide rail 3 is fixedly connected with a stopper 808, and the inner side of the stopper 808 is provided with a plurality of through holes 809 adapted to the stopper 802. The other end of the stopper 802 is in sliding contact with the inner wall of one of the through holes 809, and the through hole 809 can block the stopper 802 from moving. The blocking of the stopper 802 by the through hole 809 can prevent the unloading platform 2 from suddenly falling during unloading, increase the stability of the unloading platform 2, and further improve the personal safety of the unloading workers.

[0028] Working principle: When in use, first push the unloading device for road transport to align with the position where the truck needs to unload. When pushing the unloading device for road transport to move, the casters 11 rotate at the same time. After moving to a good position, the unloading workers can step onto the unloading platform 2, and then start the motor 5 to rotate to drive the screw rod to rotate. While the screw rod rotates, it drives the unloading platform 2 to move its position. After the unloading platform 2 moves to a suitable position, turn off the motor 5, and rotate the baffle rod 802. After the baffle rod 802 rotates, the positioning block 806 disengages from the contact with the support plate 805, and at the same time, the spring 804 pushes the push piece 803 to move, and the push piece 803 drives the baffle rod 802 to contact with the through hole 809.
