The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
As Fig. 1,2,3, shown in 4, automobile cab positioning machine lifting device of the present utility model, comprise hoist cylinder 1, guide 12, ratchet bar 11, pull piece 6 and release oil cylinder 2, ratchet bar 11 is slided with the piston rod 1-1 load of hoist cylinder 1 and with guide 12 and is joined, release oil cylinder 2 and hoist cylinder 1 load, be fitted with mount pad 10 on the hoist cylinder 1, the piece 6 of pulling is hinged on the mount pad 10, the piece 6 of pulling is provided with shifting part 5, and load retracing spring 8 on the piece 6 of pulling, be connected with wedge 3 on the plunger 2-1 of release oil cylinder 2, the lozenges 3-1 of wedge 3 can with shifting part 5 moving contacts on the piece 6 of pulling.
Shown in Fig. 2,5, for the ease of operation, mount pad 10 has two stay bearing plate 10-1, hinging supporting shaft 9 is fixed on two stay bearing plate 10-1, pull piece 6 rotational support on hinging supporting shaft 9, and perhaps hinging supporting shaft 9 rotational support are on two stay bearing plate 10-1, and 6 of the pieces of pulling are fixed on the hinging supporting shaft 9.
As shown in Figure 1, 2, 3, retracing spring 8 is a torsion spring, and this torsion spring is nested with the external part at hinging supporting shaft 9, and torsion spring one end and mount pad 10 join, and the other end joins with the piece 6 of pulling.Certainly, retracing spring 8 also can adopt the spring of other forms such as leaf spring.
As shown in Figure 1, 2, in order to guarantee wedge 3 straight-line motions, prevent to roll, also be connected with slide unit 4 on the hoist cylinder 1, slide unit 4 is positioned at the lozenges 3-1 back side of wedge 3.
Shown in Fig. 1,2,3,4, mount pad 10 is provided with spacing shelves 7, has limited step 6-1 on the piece 6 of pulling, and after the piece 6 of pulling swung to certain angle, limited step 6-1 can offset with spacing shelves 7.
Shown in Fig. 1,2,3,4, for the lozenges 3-1 that alleviates wedge 3 and the wearing and tearing between shifting part 5 peripheries, shifting part 5 rotational support are on the piece 6 of pulling.Certainly, shifting part 5 also can be fixed on the piece 6 of pulling.
As shown in Figure 2, in order to make more compact structure, reasonable, release oil cylinder 2 comprises cylinder body 2-2, plunger 2-1, inner convex platform 2-4 and spring 2-5, spring 2-5 is arranged in the cylinder body 2-2, spring 2-5 is enclosed within on the plunger 2-1, one end compresses mutually with the shoulder of plunger 2-3 the inner, and the other end compresses mutually with the inner convex platform 2-4 of cylinder body 2-2.Certainly, release oil cylinder 2 also can be the oil cylinder of other structure.
