The mounting holes on the connecting plate 35 provided at the lower ends of the four uprights 1 are fixedly connected to the compartment board of the truck compartment by mounting bolts. When carrying goods, the positioning pin 31 is pulled out, the inclined rope 33 is removed, and the extended guide rail 11 is rotated downward to the left side of the compartment board and fixed to the outer side of the compartment board by ropes, so that the truck will not be too wide.

The electric hoist 9, rechargeable battery, inverter, remote control switch and handheld switch in the present invention are all existing mature technologies, and the specific structure and principle are not described in detail.

When loading and unloading goods, the present invention rotates the extension rail 11 upward to a horizontal state, inserts the positioning pin 31 into the first sleeve 29 and the second sleeve 30, and then hangs the hook 32 at one end of the inclined rope 33 to the left end of the adjusting slot 22, and tightens the basket bolt 34 to tighten the inclined rope 33, so that the extension rail 11 and the transverse rail 8 are connected and fixed as a whole.

When it is necessary to move forward or backward, when there is cargo hoisted on the electric hoist 9 and the cargo is located in the carriage, the transport worker can push the cargo forward or backward with a little force, so that the left parallel rolling adjustment hanger 6 and the right parallel rolling adjustment hanger 7 above the transverse guide rail 8 can be moved forward or backward along the left longitudinal guide rail 2 and the right longitudinal guide rail 3. In this way, it is very convenient to realize hoisting at any place in the carriage, which fully reduces the labor intensity of manual labor.

Due to installation errors or unbalanced forces on the left longitudinal guide rail 2 and the right longitudinal guide rail 3 during multiple lifting of goods, the left longitudinal guide rail 2 and the right longitudinal guide rail 3 will not be parallel. Therefore, a left parallel rolling adjustment hanger 6 and a right parallel rolling adjustment hanger 7 with the same structure are designed. Through the rolling support of four balls 28 and the lower plate and the setting of the adjustment slot 22, when the two rollers 20 move forward and backward along the longitudinal guide rail and the right longitudinal guide rail 3 respectively, the balls 28 will move left and right, so that the lifting bolts move left and right in the adjustment slot 22 to adapt to the movement trajectory of the rollers 20. This ensures that the transport workers can push or pull the transverse guide rail 8 to move in the forward and backward direction relatively easily.

Four balls 28 are provided on each side as rolling supports. The four balls 28 are evenly arranged in a circular array, have a good force balance state, and are easy to disassemble and install.

Since the electric hoist 9 on the market generally uses alternating current, and the voltage is generally 220V, the present invention uses a rechargeable battery to convert the 220V alternating current through an inverter to power the electric hoist 9, without the need to find a power source. During the driving of the truck, the engine of the truck charges the rechargeable battery.

This embodiment does not impose any formal limitation on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
