A top fixing plate 406 is installed above the adjusting rods. When the support rod 401 slides, it will cause the adjusting rod 404 to change its position, causing the upper adjusting mechanism 6 to lift and lower.

[0028] The lifting mechanism is driven by a servo motor 5, and the servo motor is powered by a power source. The forward and backward movement of the joystick of the operation control device 2 can achieve the forward and reverse rotation of the motor, which can drive the threaded rod 402 to rotate, and then drive the support rod 401 to slide in the chute.

[0029] It further includes an adjusting mechanism 6. The upper part of the adjusting mechanism 6 is fixedly connected to the loading platform 7. The adjusting mechanism includes an adjusting platform bottom plate 601, slideways 602, bearing fixing blocks 603, limit connection blocks 604, a handle 605, and a threaded rod 606. The two slideways are respectively fixed on both sides of the bottom plate. The two bearing fixing blocks are fixedly connected to the adjusting platform bottom plate. Bearings are installed inside the bearing fixing blocks. The threaded rod is connected to the bearing fixing blocks. A limit connection block is also arranged in the middle section of the threaded rod. One end of the threaded rod is connected to the handle.

[0030] The adjusting platform is of a two-layer structure. The upper and lower layer adjusting mechanisms have the same structure, that is, it includes a second-layer adjusting platform bottom plate 607, second-layer slideways 608, second-layer bearing fixing blocks 609, second-layer limit connection blocks 610, second-layer handles 611, and second-layer threaded rods 612. The two adjusting platform bottom plates are arranged in parallel, and the mechanisms on them are arranged with a 90° difference, that is, the upper-layer slideways and the lower-layer slideways are vertically arranged, the upper-layer threaded rods and the lower-layer threaded rods are vertically arranged, and the upper end of the lower-layer limit connection block is connected to the adjusting platform bottom plate of the upper-layer adjusting mechanism.

[0031] The two slideways 602 are fixed on both sides of the bottom plate 601. The two bearing fixing blocks 603 are fixedly connected to the bottom plate 601 at the bottom of the adjusting mechanism 6. The threaded rod 606 is fixedly connected to the bearing fixing blocks 603. The limit connection block 604 is threadedly connected to the threaded rod 606, and the limit connection block 604 is fixedly connected to the bottom plate of the upper-layer adjusting mechanism. One end of the threaded rod is connected to the handle 605. By rotating the handle 605, the upper platform can be driven to slide along the slideway 602.

Crane connection seats are fixed above the two main cross beams. The side bearing is connected to the rear end of the vehicle frame.

[0035] When the four rear adjustment wheels 801 are applied, the moving direction of the operation platform can be adjusted. At the same time, the four front wheels and the four rear wheels can effectively prevent the wheels from getting stuck in the track groove when the operation platform passes through the track groove; Crane connection seats 101 are fixed above the two main cross beams 805. When the crane rotates left and right to prepare for lifting a heavy object, the side bearings 803 on both sides need to be opened, and the support disk is in contact with the ground to play the role of a side bearing to prevent the platform from tipping during the lifting operation.

[0036] Taking the assembly of the transition coupler as an example, the operator can push the device to the storage location of the equipment to be installed. By operating the control device, using the power provided by the storage battery and the hydraulic pressure conducted by the hydraulic system device, the crane lifts the equipment and places it on the load platform at the front end of the device. Then, the boom is retracted, and the equipment to be assembled is transferred to the vicinity of the installation location. The equipment is assembled through the lifting and adjustment functions of the lifting mechanism and the adjustment mechanism; In another working condition, the equipment to be installed is lifted by the device, placed on the load platform, and then the boom is retracted. The equipment is transported to the designated installation location, and the crane is used to lift the equipment again for installation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
