Figure 2As shown, the lifting device 000 mainly includes a chain mechanism 100 and a beam mechanism 200. The lifting device 000 is described in detail below:
[0027] The chain mechanism 100 includes a frame chain 110, a crossbeam chain 120 and a lifting ring 130. Specifically, one end of the crossbeam chain 120 and the frame chain 110 are both connected to the lifting ring 130; one end of the crossbeam chain 120 away from the lifting ring 130 is connected to the crossbeam 210, and one end of the frame chain 110 away from the lifting ring 130 is connected to the frame 001. Preferably, the frame chain 110 is connected to the frame 001 through a frame hook 111, and the frame hook 111 with an arc-shaped opening is convenient for hooking the frame 001; the lifting ring 130 is elliptical.
[0028] Regarding the crossbeam mechanism 200: Figure 3 As shown, the crossbeam mechanism 200 is connected to the chain mechanism 100 through the crossbeam chain 120. The crossbeam mechanism 200 includes a crossbeam 210, an upper hanging plate 211, a lower hanging plate 212, a counterweight chain 220 and a horn sliding hook 221. Specifically, the top of the crossbeam 210 is symmetrically provided with an upper hanging plate 211 about the central axis of the crossbeam 210, and the upper hanging plate 211 is connected to the crossbeam chain 120. The crossbeam 210 is sleeved with a lower hanging plate 212, which can reciprocate along the axial direction of the crossbeam 210 to adjust the spacing between the lower hanging plates 212. Preferably, four lower hanging plates 212 are provided, and two lower hanging plates 212 are provided within the stroke between the upper hanging plates 211, and the other two lower hanging plates 212 are provided within the stroke between the upper hanging plates and the end of the crossbeam 210.
