DETAILED DESCRIPTION
[0014] In the figure, the utility model is provided with a balancing sling 4, which is connected to the four corners of the adjustable hanger 3 via a steel cable. The balancing sling 4 includes a lifting wheel 17 and side plates 20 fixed on both sides of the lifting wheel 17. Long holes are longitudinally processed on the side plates 20 on both sides, and studs 12 are inserted into the long holes. The studs 12 can slide along the long holes. A sprocket 18 is installed in the middle of the stud 12. Both ends of the stud 12 are fixed on a slider 15. A spring 13 is installed between the slider 15 and the bottom of the side plate 20. Limiting pins 19 and locking plates 14 are respectively installed on the side plates 20 below and above the sprocket 18. A chain 16 is meshed on the sprocket 18. The steel cable connection at both ends of the chain 16; the adjustable hanger 3 includes two parallel longitudinal beams 5 on the left and right, telescopic cross bars 11 are fixed at the front and rear ends of the longitudinal beam 5, and a positioning cross pin 10 is provided on the telescopic cross bar 11. The front and rear portions of the longitudinal beam 5 are respectively installed with a front auxiliary hanging point plate 7 and a rear auxiliary hanging point plate 8, and the front and rear ends of the longitudinal beam 5 are respectively installed with a front main hanging point plate 6 and a rear main hanging point plate 9, and the front main hanging point plate 6 and the rear main hanging point plate 9 are processed with hanging holes at intervals, and the shackle 2 is locked in the hanging holes. The lower end of the shackle 2 is connected to a wire rope sling 1, one end of the telescopic cross bar 11 is hinged to the longitudinal beam 5 on the left, and the other end of the telescopic cross bar 11 is connected to the longitudinal beam 5 on the right via a vertical pin 21.
[0015] like Figure 1 , Figure 2As shown, by quickly disassembling and assembling the shackle 2, the wire rope sling 1 is placed at different positions of the front auxiliary lifting point plate 7, the rear auxiliary lifting point plate 8, the front main lifting point plate 6 and the rear main lifting point plate 9 of the longitudinal beam 5, so as to meet the requirements of lifting different sizes of goods in the length direction. When lifting a two-bridge vehicle or a cannon, the front and rear wheel slings are respectively connected to the front main lifting point plate 6 and the rear main lifting point plate 9. When installing a two-bridge vehicle or a cannon, the front and rear wheel slings are respectively connected to the 5 holes on the top, which can be selected according to the size of the equipment or the position of the center of gravity of the equipment; when lifting a three-bridge vehicle or a cannon, the front wheel sling is connected to the front main lifting point plate 6, and the slings of the two rear wheels, the rear one is connected to the rear main lifting point plate 9, and the middle one is connected to the rear auxiliary lifting point plate 8; when lifting a small vehicle or a cannon, the front and rear wheels are respectively connected to the front auxiliary lifting point plate 7 and the rear auxiliary lifting point plate 8. By adjusting the length of the telescopic crossbar 11 and using the cross pin 10 for insertion and positioning, the requirements of lifting different sizes of goods in the width direction can be met.
[0016] like Figure 3 , Figure 4 As shown, the cargo is fixed reliably, and the crane is connected to the lifting wheel 17. If there is a tilt during lifting, the load can be unloaded, and the crane can be moved in the direction of the center of gravity offset and then lifted until it is balanced, so as to achieve the purpose of balancing the center of gravity of the lifted equipment. When carrying, the load overcomes the upward elastic force of the spring 13, and drives the sprocket 18 through the chain 16 to act on the stud 12 and the slider 15, so that the stud 12 slides down within the limit range of the long hole of the side plate 20, and slides down to the bottom limit pin 19 stuck between the teeth of the sprocket 18, and the sprocket 18 cannot rotate. At this time, the sling is in a stable state and can be lifted smoothly; if the same specification of load is lifted, the locking plate 14 can be locked vertically, and the balance sling 4 is maintained in a well-adjusted balanced state, and the cargo of the same specification and weight can be lifted continuously; if the locked state is to be released, just turn the locking plate 14 to expose the spring pin, and after unloading, under the action of the spring 13, the slider 15, the stud 12, the sprocket 18 and the chain 16 go up to restore the initial state.
[0017] like Figure 5 As shown, when the adjustable hanger is withdrawn, the vertical pin 21 is pulled out, the telescopic cross bar 11 is adjusted to be shortened to the shortest state and rotated 90 degrees inward, and the vertical pin 21 is inserted to fix it.
