[0006] Furthermore, the fixing mechanism includes a bent pipe, a first connecting rod, a support rod, and a second connecting rod; the upper ends of the two second U-shaped blocks on the side away from the pickup truck are jointly fixed to the bent pipe, the ends of the two second U-shaped blocks on the side close to each other are jointly fixed to the second connecting rod, two first connecting rods are jointly fixed between the bent pipe and the second connecting rod, one end of the support rod is fixed to both sides of the lower end of the bent pipe, and the other end of the support rod is fixed to one side of the second U-shaped block.

[0007] Furthermore, the connecting mechanism includes a rotating tube, a first groove, a first connecting block, and a connecting plate; the rotating tube is rotatably installed on the side wall of the bent tube, and multiple first grooves are evenly opened on the inner wall of the rotating tube. A friction-reducing bearing ring is fixedly connected to the inner wall of the first groove, and multiple first connecting blocks are fixedly connected to the lower end of the rotating tube. The lower ends of the multiple first connecting blocks are jointly fixedly connected to the connecting plate.

[0008] Furthermore, the power mechanism includes a module box, a delivery pipe, and an electric winch; the oil inlet end of the tilting cylinder is fixedly connected to one end of the delivery pipe, the other end of the delivery pipe is fixedly connected to the module box, and the lower end of the connecting plate is bolted to the electric winch. The module box is located inside the pickup truck.

[0009] Furthermore, the support mechanism includes a fixed rod, a third rotating column, an electric cylinder, a second connecting block, a gasket, a support column, a fourth rotating column, a third connecting block, and a fifth rotating column. The fixed rod is fixedly connected to the lower end of the pickup truck. The third rotating column is rotatably mounted on both sides of the lower end of the fixed rod. The electric cylinder is fixedly connected to the side wall of the third rotating column. The output end of the electric cylinder is fixedly connected to the fifth rotating column.

[0012] The beneficial effects of this utility model are as follows: First, the first U-shaped block is installed on the pickup truck bed with bolts. Before use, the two electric cylinders at the bottom of the pickup truck are opened. The electric cylinders push the support column to rotate. When the shim rotates to the ground, the electric cylinders are closed. The two support columns support the pickup truck, ensuring the smooth operation of the gantry crane's tilting action. Then, oil is transported to the inside of the tilting cylinder through the module box and conveying pipe. The tilting cylinder pushes the second U-shaped block to rise. Since the first and second U-shaped blocks are rotatably connected, the second U-shaped block rotates around the end connected to the first U-shaped block, facilitating the unfolding and retraction of the gantry crane. When the other end of the second U-shaped block... When the end rotates to its highest point, the electric winch is adjusted to the most suitable angle by rotating the rotating tube. Then, the object is hung on the lower end of the electric winch, and the electric winch is turned on to move the object into the truck bed. Finally, the tilting cylinder is turned on, which rotates the second U-shaped block downwards. The shock-absorbing pads inside the second U-shaped block play a shock-absorbing role, preventing the second U-shaped block from colliding violently with the first U-shaped block. Because the rotating tube is equipped with a friction-reducing bearing ring, it can prevent the electric winch from colliding with the side wall of the truck bed. This solves the problem of damage caused by collisions between parts during operation of existing folding pickup truck gantry cranes, and extends the service life of the equipment.

[0028] Please see Figure 1 In this embodiment, the diameter of the tilting cylinder 13 is smaller than the width of the first U-shaped block 11, and the tilting cylinder 13 can be placed inside the first U-shaped block 11.

[0029] Working principle: First, the first U-shaped block 11 is installed on the cargo bed of the pickup truck 6 using bolts. Before use, the two electric cylinders 53 at the lower end of the pickup truck 6 are opened. The electric cylinders 53 push the support column 56 to rotate. When the shim 55 rotates to the ground, the electric cylinders 53 are closed. The two support columns 56 support the pickup truck 6. Then, oil is transported to the inside of the tilting cylinder 13 through the module box 41 and the delivery pipe 42. The tilting cylinder 13 pushes the second U-shaped block 14 to rise. Since the first U-shaped block 11 and the second U-shaped block 14 are rotatably connected, the second U-shaped block 14 rotates around the end connected to the first U-shaped block 11. When the other end of the second U-shaped block 14 rotates to the highest point, the electric winch 43 is adjusted to the most suitable angle by rotating the rotating tube 31. Then, the object is hung on the lower end of the electric winch 43, and the electric winch 43 is turned on to move the object into the carriage. Finally, the tilting cylinder 13 is turned on, and the tilting cylinder 13 rotates the second U-shaped block 14 downward. The shock-absorbing pad 16 inside the second U-shaped block 14 plays a shock-absorbing role to prevent the second U-shaped block 14 from colliding violently with the first U-shaped block 11. Since the rotating tube 31 is equipped with a friction-reducing bearing ring 35, it can prevent the electric winch 43 from colliding with the side wall of the carriage.
