The first flip arm 3, the second flip arm 5, the third flip arm 6 and the fourth flip arm 8 are provided at the left and right of the base 1, realizing a symmetrical arrangement on both sides.

[0041] The entire boom is a combined gantry structure, with the left and right booms arranged symmetrically. The first flip boom is fixedly connected by the base, and then other moving structural parts are connected in sequence from bottom to top. Adjacent components are connected by rotating pins code-named X1 to X13. When working, all components can rotate around their connecting pins. The hanger and hook are jointly suspended and supported by the booms on both sides. When in motion, the corresponding cylinders on both sides are extended and retracted at the same time, and the displacement sensor feedback control ensures the consistency of the extension and retraction displacement of the cylinders, so that the hanger, i.e. the hook, always maintains balance during the flipping movement.

[0042] The fourth flip arm 8 is hinged to the hanger 10 through the twelfth pin X12, and a balance tension spring 9 is connected between the inner and outer sides of the fourth flip arm 8 and the hanger 10, and the hanger 10 is provided with hooks 13 arranged in a horizontal and vertical lattice. The hanger is mainly a square frame structure, and its size is the same as that of the slide.

A locking pin mechanism is provided between the column 15 and the second flip arm 5, and the locking pin mechanism uses a sixth pin X6 to penetrate between the column 15 and the second arm to achieve locking when not in operation.

[0044] refer to Figure 5 As shown, the workflow of the present application is as follows: when unloading is required, the sixth pin X6 is first removed, and then the implement 200 is moved from the middle position of the base 1 to the side, and is hung on the hook of the hanger, and the hanger is kept balanced by the balance spring 9. The second oil cylinder 4 extends to raise the third flip arm 6, the third oil cylinder 7, the fourth flip arm 8, the balance spring 9, and the hanger 10, thereby driving the implement 200 to rise.

[0045] When the second oil cylinder 4 extends to make the machine 200 complete the upward movement, the first oil cylinder 2 and the third oil cylinder 7 begin to extend, so that the machine moves outside the flat car. When the machine passes the edge of the flat car, the fourth oil cylinder 12 and the second oil cylinder 4 begin to shrink, and the first oil cylinder 2 and the third oil cylinder 7 continue to extend, so that the first flip arm 3, the second flip arm 5, the third flip arm 6, and the fourth flip arm 8 are flipped around each rotating connecting axis at the same time, so that the hanger and the machine move outward and downward at the same time, so that the machine can be lowered to the roadbed platform smoothly and quickly.

[0046] After the tool is taken away by the operator, the boom is retracted to the platform under the reverse action of the linkage cylinder. When the tool is retracted, the entire unloading process is repeated in reverse.

[0049] The workflow of this application is as follows: first plan the placement of the equipment according to its type, quantity, weight, shape, and lifting point. When the equipment is transported, the loading and unloading structure is in its original state, the boom is recovered and fixed, and the equipment is classified and placed on the slide of the base. The slide slides to the middle of the base and is fixed to prevent the vehicle body from being unloaded. When the equipment is transported to the section of use for unloading, the slide slides to the bottom of the hanger, the hook is lifted, and the equipment is flipped down and lowered onto the track roadbed by rotating and telescoping the boom. Then the boom is recovered and the flat car is driven away from the construction area. When the construction work is completed and the equipment is recovered, the flat car drives into place and the operation process of unloading the equipment is repeated in reverse.
