Description
Technical field
The utility model relates to the weight-lifting equipment technical field, particularly a kind of slab clamp open-and-close mechanism.
Background technology
The dead-weight mechanical clamp has been used the work that a kind of open-and-close mechanism (switch circuit controller) is realized clamp mostly at present.This open-and-close mechanism (switch circuit controller) mainly plays two effects: the one, the disengagement that realizes the slab clamp lower and upper cross-member by open-and-close mechanism be connected, to realize the gripping slab function of clamp.The 2nd, this gripping tangles the clamp cross sill by this open-and-close mechanism the effect of (packing up clamp) under the state of not gripping slab, and this moment, the major part of this open-and-close mechanism carrying clamp was conducted oneself with dignity.After using certain work times, owing to reasons such as set pin or contact abrasion distortion, the carrying of open-and-close mechanism T shape hook, misoperation, clamp external force, the problem of inter deterioration, open-and-close mechanism reverse, T shape hook gib head abrasion deformation and fracture will appear in this open-and-close mechanism, cause this open-and-close mechanism to use, finally cause the serious potential safety hazard of clamp from falling in the air.Therefore, if stop the appearance of problems, must avoid open-and-close mechanism under loaded state, to work, namely avoid open-and-close mechanism to realize the linkage function of clamp lower and upper cross-member.
The utility model content
The purpose of this utility model is in order to overcome the problems referred to above, and a kind of blast furnace hydraulic system automatic switching control equipment is provided.
For achieving the above object, the method that the utility model adopts is: a kind of slab clamp open-and-close mechanism, comprise the slab clamp entablatrance, the slab clamp cross sill, switch circuit controller, described switch circuit controller is arranged at the slab clamp entablatrance, between the slab clamp cross sill, between described slab clamp entablatrance and slab clamp cross sill, also be provided with a coupling hook, described coupling hook one end is installed in the lower end of described slab clamp entablatrance, be provided with the supporting seat of linking up with for support and connection at described slab clamp cross sill, on the slab clamp cross sill, also be provided be used to the protruding block that tangles coupling hook.
As a kind of improvement of the present utility model, be provided with runner at described supporting seat and described coupling hook touching position.
As a kind of improvement of the present utility model, be provided with in the inboard of described coupling hook one section circular-arc.
As a kind of improvement of the present utility model, described switch circuit controller comprises connecting rod, lower link, and T shape gib head, described T shape gib head is fixed on the described upper connecting rod, is used for connecting described upper connecting rod and lower link.
As a kind of improvement of the present utility model, described lower link one end links to each other with described upper connecting rod, and the other end links to each other with described coupling hook.
The beneficial effects of the utility model are:
The utility model is simple in structure, result of use is good, the weight that is used for the supporting clamp by coupling hook is set, reduced the load-bearing of switch circuit controller, prevented the problem of the abrasion deformation of switch circuit controller, improved the service life of switch circuit controller, improved safety performance, also improved simultaneously the safety performance of slab clamp, by circular arc being set at coupling hook and at supporting seat runner being set, rotation that can coupling hook is more smooth and easy, has reduced wearing and tearing, has improved serviceability and the service life of mechanism.
