For example, fixed-installation cranes cannot flexibly change their working position as needed. While models with ordinary casters can be pushed manually, operation is inconvenient, requires physical labor from the operator, and poses certain safety hazards. Utility Model Content

A slewing seat 3 is provided between the top of the column 2 and the cantilever 4. The slewing seat 3 includes an external gear disc 3.1 fixed to the top of the column 2, a rotating support 3.2 rotatably sleeved at the middle of the external gear disc 3.1, a swing motor 3.3 fixed to one side of the top surface of the rotating support 3.2, and a swing gear 3.4 fixedly mounted on the bottom of the power output shaft of the swing motor 3.3 and meshing with the external gear disc 3.1. The cantilever 4 is fixed to the top surface of the rotating support 3.2. That is, the swing motor 3.3 drives the swing gear 3.4 to rotate relative to the external gear disc 3.1, thereby realizing the horizontal swing of the cantilever 4. The hoist 5 is used to lift and lower objects.

[0016] The bearing seat 6 is fixed to the center of the four edges of the top surface of the base 1.

[0017] The support component 7 includes a support arm 7.1, a caster wheel 7.3 mounted on the bottom surface of the outer end of the support arm 7.1, and a support plate 7.2 fixed to the top surface of the outer end of the support arm 7.1. The inner end of the support arm 7.1 is fixedly connected to a short shaft 7.4 that is rotatably fitted with a bearing and a shaft seat 6, and a prism 7.5 fixedly connected to the inner end of the short shaft 7.4.

[0018] The steering transmission components 8 are fixed to the top surface of the base 1 and located inside the axle seat 6. The inner end of the support arm 7.1 is fixedly connected to the power output shaft of the steering transmission component 8. The steering transmission component 8 also includes a right-angle commutator 8.1 fixed to the top surface of the base 1 and located inside the axle seat 6. The driven gear 8.2 is fixedly fitted onto the bottom end of the power input shaft of the right-angle commutator 8.1. A bushing 8.3 is fixedly connected to the power output shaft of the right-angle commutator 8.1, and the bushing 8.3 is circumferentially inserted into the prism 7.5.

[0019] The linkage turntable 9 is mounted on the outer periphery of the center of the bottom surface of the base 1, and is simultaneously connected to the power input shafts of the four steering transmission components 8. The linkage turntable 9 is an internal gear slewing bearing whose outer ring is fixedly connected to the outer periphery of the center of the bottom surface of the base 1. Driven gears 8.2 mesh with the rotating internal gear ring of the linkage turntable 9.

[0020] The drive unit 10 includes a drive motor 10.1 fixed to the top surface of the base 1, with its power output shaft passing through the bottom surface of the base 1. A drive gear 10.2 is fixedly fitted onto the bottom end of the power output shaft of the drive motor 10.1. The drive gear 10.2 meshes with the rotating internal gear ring of the linkage turntable 9. That is, the drive unit 10 is used to drive the transmission part of the linkage turntable 9 to rotate. A new energy battery is installed on the base 1 to provide power to the drive motor 10.1. The start and stop of the drive motor 10.1 are achieved via remote control.

[0021] The lifting unit of the AGV mobile chassis 11 is fixed to the center of the bottom surface of the base 1. The AGV mobile chassis 11 is the standard chassis of Linghou Robot TJ-Q7. TJ-Q7 is a multi-functional intelligent transportation platform that uses differential chassis drive and electric lifting as its main forms, which facilitates high-load, efficient and flexible movement, and has autonomous navigation capabilities.

[0022] In summary, during normal lifting operations, the support plate 7.2 is located at the bottom and rests on the ground. When the crane needs to be moved, the lifting structure of the AGV mobile chassis 11 first lifts the entire crane through the base 1 until the support plate 7.2 is lifted off the ground and can be rotated.

[0023] Subsequently, the drive motor 10.1 drives the internal gear ring of the linkage turntable 9 to rotate through the drive gear 10.2. The internal gear ring of the linkage turntable 9 synchronously drives the four driven gears 8.2 to rotate. The rotation of the driven gears 8.2 drives the support member 7 to rotate as a whole through the right-angle reversing device 8.1, so that the caster wheel 7.3 rotates to the lower side. Then, the lifting structure of the AGV mobile chassis 11 falls, so that the caster wheel 7.3 contacts the ground. Then, the AGV mobile chassis 11 transfers the entire crane. During the transfer, the caster wheel 7.3 of the support member 7 can provide stable support for the entire crane.

[0024] After the crane is moved into position, the support plate 7.2 is rotated to the lower side so that the support plate 7.2 provides stable support, so as to maintain the overall stability of the crane during lifting operations.
