Description
Technical field
The present invention relates to a kind of open/close device for hoist of controlling the suspender opening and closing movement.
Background technology
In the suspender use procedure, before lifting, require suspender to keep open state, so that material can enter in the opening of suspender smoothly, when needs lift by cranes, make again the suspender can be closed, to clamp material, so just need to a kind of open/close device for hoist.The existing employed switch circuit controller of suspender mainly contains two kinds, a kind of is as representative take Chinese patent ZL200520070269.3, the weak point of this open/close device for hoist is: 1, three waveform spigot surfaces are arranged, comprise two waveform master spigot surfaces and an auxiliary spigot surface, complex structure, difficulty of processing is large; 2, in the on-off action process, the friction position of parts is many, causes fault rate higher.Another kind is as representative take Chinese patent ZL 200810228123.5, the weak point of this open/close device for hoist is: 1, will use this switch circuit controller, need to fixedly fixed link 9 and the hook 10 of switch circuit controller be set at suspender, these parts are by the structure complicated of suspender, 2, switch circuit controller and attached parts thereof can not be symmetrical with the axis of suspender, when mentioning suspender, can make suspender produce deflection like this, be unfavorable for workman's operation.
Summary of the invention
Goal of the invention, the above-mentioned technical matters that exists in order to solve prior art.
The present invention has designed a kind of sliding type shutter for lifting appliances, technical scheme is: its structure comprises sliding sleeve 1, plug 2, spring 3, automatic pinning 4, guide rod 5, tapered sleeve 6, sliding sleeve 1 bilateral symmetry is provided with spring perch 1-1, guide rod 5 is provided with support ring 5-1 and projection 5-2, tapered sleeve 6 is provided with transition rings 6-1, the complete interlock of upper surface of the lower surface of guide rod supports ring 5-1 and tapered sleeve transition rings 6-1, sliding sleeve 1, tapered sleeve 6 all is enclosed within on the guide rod 5, guide rod 5 and tapered sleeve 6 can be free to slide in sliding sleeve 1, spring 3 and automatic pinning 4 are located among the spring perch 1-1, and plug 2 is captiveed joint with spring perch 1-1.
Described spring perch 1-1, plug 2, spring 3, automatic pinning 4 all are symmetrically arranged with two.
This switch circuit controller relies on the switching of finishing switch circuit controller that slides up and down of guide rod 5 and tapered sleeve 6.When initial position, be suspended on the automatic pinning 4 at guide rod supports ring 5-1, this moment, suspender relied on switch circuit controller to keep open state; When needs clamp material, allow guide rod 5 upward movements, because the position-limiting action of projection 5-2, tapered sleeve 6 is also along with guide rod 5 upward movements, when the transition rings 6-1 of tapered sleeve 6 with after automatic pinning 4 contacts, the transition rings 6-1 of tapered sleeve 6 is two automatic pinning 4 spreadings, because the pressuring action of spring 3, the transition rings 6-1 of tapered sleeve 6 finally hangs on the automatic pinning 4, at this moment allow guide rod 5 move downward, when the support ring 5-1 of guide rod 5 contacted with tapered sleeve, automatic pinning 4 was again by spreading, because the lower surface of guide rod supports ring 5-1 cooperates fully with the upper surface of tapered sleeve transition rings 6-1, so automatic pinning 4 can slide into along the periphery of support ring 5-1 and transition rings 6-1 the top of guide rod supports ring 5-1, this moment, support ring 5-1 and the automatic pinning 4 of guide rod were thrown off, and suspender can be freely closed, thereby pick up material.
Adopt the open/close device for hoist of this technical scheme, structurally saved the waveform spigot surface, make designs simplification, and the difficulty of processing also reduces a lot; The mode of utilizing automatic pinning 4 to hang guide rod supports ring 5-1, safe and reliable, guaranteed suspender safety in use.The present invention has continued the advantage of Chinese patent ZL200520070269.3 in addition, can be installed on the axis of suspender, and when using suspender, suspender is not easy to occur deflection, is convenient to workman's operation.But this switch circuit controller can not bear too large gravity, so than being more suitable for the small hoist tool.

The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Sliding type shutter for lifting appliances comprises: sliding sleeve 1, plug 2, spring 3, automatic pinning 4, guide rod 5, tapered sleeve 6, sleeve 1 bilateral symmetry is provided with spring perch 1-1, guide rod 5 is provided with support ring 5-1 and projection 5-2, tapered sleeve 6 is provided with transition rings 6-1, the complete interlock of upper surface of the lower surface of guide rod supports ring 5-1 and tapered sleeve transition rings 6-1, sliding sleeve 1, tapered sleeve 6 all are enclosed within on the guide rod 5, guide rod 5 and tapered sleeve 6 can be free to slide in sliding sleeve 1, spring 3 and automatic pinning 4 are located in the spring perch, and plug 2 is connected with spring perch 1-1.This switch circuit controller relies on the switching of finishing switch circuit controller that slides up and down of guide rod 5 and tapered sleeve 6.When suspender used this switch circuit controller, sliding sleeve 1 was arranged on the lifting plate 7, and guide rod 5 is connected with supporting plate 8.
When initial position, be suspended on the automatic pinning 4 at guide rod supports ring 5-1, lifting plate 7 and the vertical distance of supporting plate 8 are fixed, this moment, suspender relied on switch circuit controller to keep open state.Such as Fig. 1,9.
When needs clamp material, allow guide rod 5 upward movements, because the position-limiting action of projection 5-2, tapered sleeve 6 is also along with guide rod 5 upward movements, when the transition rings 6-1 of tapered sleeve 6 contacts with automatic pinning 4, the transition rings 6-1 of tapered sleeve 6 is two automatic pinning 4 spreadings.Such as Fig. 5.
Because the pressuring action of spring 3, the transition rings 6-1 of tapered sleeve 6 finally hangs on the automatic pinning 4.Such as Fig. 6.
At this moment allow guide rod 5 move downward, the support ring 5-1 of guide rod 5 contacts fully with tapered sleeve.Such as Fig. 7.
Then, automatic pinning 4 is again by spreading, because the lower surface of guide rod supports ring 5-1 and the complete interlock of upper surface of tapered sleeve transition rings 6-1, so automatic pinning 4 can slide into along the periphery of support ring 5-1 and transition rings 6-1 the top of guide rod supports ring 5-1, this moment, support ring 5-1 and the automatic pinning 4 of guide rod were thrown off, this moment, lifting plate 7 can freely change with the vertical distance of supporting plate 8, and suspender can be freely closed, thereby pick up material.Such as Fig. 8,10.
When needs allow suspender recover open state, repeat above-mentioned motion process, guide rod supports ring 5-1 is suspended on the automatic pinning 4 will move to the described state of Fig. 6 by state shown in Figure 7 again.
