Two symmetrically distributed lifting mechanical arms 106 are fixed to the bottom surface of the top plate 104, and a winding drum 107 is installed on the upper surface of the top plate 104. A sling 108 is wound around the outer side of the winding drum 107, and one end of the sling 108 is fixed to the winding drum 107. The other end of the sling 108 extends from the middle of the top plate 104 to the bottom of the top plate 104. The movable end of the sling 108 has a plurality of branch ends. The number of branch ends of the sling 108 is greater than two. The branch ends of the sling 108 are detachably installed with a sling 109. The bottom end of the top plate 104 is also detachably installed with a plurality of first cameras 111. The plurality of first cameras 111 are distributed in a circular array around the axis of the top plate 104. The first cameras 111 are used to shoot the site environment and identify the device's travel route. At the same time, the site cargo is scanned and identified, which facilitates the device to grab or store the cargo. Subsequently, the lifting mechanical arm 106 and the sling 109 at the branch end of the sling 108 are used to clamp or suspend the cargo to separate the cargo from the ground or stored objects. Then, the crawler mobile vehicle 102 is used to drive the crane 1 to move as a whole to change the position of the cargo after being lifted. At the same time, the crawler mobile vehicle 102 is used to allow the crane 1 to move freely in the work site.

[0020] The sling 109 includes a hook and a manual permanent magnetic suction cup. A driving shaft is fixedly passed through the axial direction of the winding drum 107. Fixed blocks are installed on the outer sides of both ends of the driving shaft through ball bearings. The fixed blocks are fixed to the top plate 104. One end of the driving shaft is connected to a driving motor through a fixing pin. The driving motor is fixed to the upper surface of the top plate 104.

Both ends of the support spring 305 are in contact with the crawler-type mobile chassis 301 and the load-bearing plate 302 respectively. The support spring 305 and the support damping rod 306 are used to elastically buffer the load-bearing plate 302 to reduce the impact of the cargo on the load-bearing plate 302. The pressure of the support damping rod 306 is reduced by the support spring 305 to avoid damage to the support damping rod 306 due to excessive weight of the cargo.

[0024] A second camera 304 is also detachably installed on the upper surface of the crawler mobile chassis 301, and a protective support plate 303 is provided between every two adjacent support springs 305.

The tightening ring 406 is used to tighten the plurality of connecting rods 401 toward the middle of the top plate 104 to prevent the connecting rods 401 from rotating outward.

[0026] A strip groove is provided on the outer surface of the connecting rod 401, and a hydraulic adjustment rod 402 is fixedly connected to the inner side of the strip groove. The movable end of the hydraulic adjustment rod 402 faces downward and is fixed with a contact block 403. A movable auxiliary wheel 404 is detachably installed on the bottom end of the contact block 403. The connecting rod 401, the hydraulic adjustment rod 402, the contact block 403 and the movable auxiliary wheel 404 form an inclined support rod to assist in supporting the top plate 104 from the front and rear of the top plate 104, thereby preventing the crane 1 from tilting forward and backward during the movement, thereby ensuring the safety of the crane 1 when moving.

[0027] Four reinforcing filling plates 405 are provided between the top of the contact block 403 and the bottom of the connecting rod 401. Two symmetrical circular through holes are penetrated through the top of the contact block 403. A double-headed electric telescopic rod 407 is fixedly installed inside the circular through hole. The two ends of the double-headed electric telescopic rod 407 are respectively fixed to the two reinforcing filling plates 405. The reinforcing filling plates 405 are used to connect and support the connecting rod 401 and the contact block 403, thereby reducing the bearing pressure of the hydraulic adjustment rod 402 and avoiding damage to the hydraulic adjustment rod 402 due to excessive bearing pressure. At the same time, the position of the reinforcing filling plate 405 can be changed by the double-headed electric telescopic rod 407, so that there is no obstruction between the contact block 403 and the connecting rod 401, so that the hydraulic adjustment rod 402 drives the contact block 403 to approach the connecting rod 401, separates the contact block 403 from the ground, and facilitates the movement of the carrier 3 in and out from under the top plate 104.
