Abstract
The utility model discloses a jaw breaker locking spring safety device which comprises a spring pull rod connected with a jaw breaker movable jaw and a cover plate, a bolt group and a device body which are assembled on the spring pull rod. The device body comprises a locking cap. The spring pull rod comprises a threaded rod body and a spring body attached to the surface of the threaded rod body. The cover plate and the bolt group sequentially sleeve the threaded rod body to be locked with outer threads on the threaded rod body and control elastic tension of the spring body. The locking cap comprises a cap body and a rod body connected with the cap body, and inner threads matched with the threaded rod body are arranged in the rod body. The threaded rod body is in screwing fit with the locking cap. Due to the fact that the safety device arranged on the spring pull rod blocks the breaker locking spring possibly flying out, the safety protection problem of the existing jaw breaker locking spring is well solved simply.
Description
Technical field
The utility model relates to protective device technical field, relates generally to a kind of jaw crusher locking spring safety device.
The normal work of jaw crusher is turned round and is made the jaw realization that swings back and forth by eccentric shaft.And on jaw crusher upper spring pull bar and pull bar external locking spring, swinging back and forth of moving jaw is the compression by locking spring---releases---is compressed and realized.
Locking spring utilizes a bolt group pretension.In when work, bolt group is subject to dynamic loading, and in long-term work, bolt group fatigue is impaired, causes locking spring may in the time of work, be subject to the locking spring elastic force disintegrating machine that flies out, and causes the damage of injury to personnel or other machine.
Utility model content
In order to address the above problem, the utility model provides a kind of jaw crusher locking spring safety device, and this apparatus structure is simple, uses reliably, can effectively prevent from that locking spring from flying out to damage accident.
The purpose of this utility model is carried out specific implementation by the following technical programs: a kind of jaw crusher locking spring safety device, comprise the spring pull bar being connected with the motor-driven jaw of jaw crushing, be assemblied in cover plate, bolt group and device body on spring pull bar, described device body comprises locking cap; Described spring pull bar comprises the screw thread body of rod and the spring body that is attached to described threaded rod surface, and cover plate and bolt group order are socketed on the described screw thread body of rod, with the external screw thread locking on the screw thread body of rod, the elasticity tension of control spring body; Described locking cap comprises cap body and the body of rod being connected with cap body, the internal thread that the built-in and described screw thread body of rod of the described body of rod coordinates; The body of rod of the described screw thread body of rod and described locking cap screws.
Further, described cap body comprises four pastes that are evenly distributed.
The jaw crusher locking spring safety device that the utility model provides, stops the disintegrating machine locking spring that may fly out by the safety device being arranged on spring pull bar, better and has simply solved the safeguard protection problem of jaw crusher locking spring.
Brief description of the drawings
For the technical scheme of clearer explanation the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparent, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the jaw crusher locking spring safety device assembling cross-sectional view described in the utility model embodiment.
Fig. 2 is the jaw crusher locking spring safety device locking cap perspective view described in the utility model embodiment.
Fig. 3 is the jaw crusher locking spring safety device assembly structure schematic diagram described in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is carried out to clear, complete description; obvious described embodiment is only a part of embodiment of the present utility model; not whole embodiment; based on the embodiment in the utility model; those of ordinary skill in the art are not paying the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As Figure 1-3, a kind of jaw crusher locking spring safety device described in the utility model embodiment, comprise the spring pull bar 1 being connected with the motor-driven jaw of jaw crushing, be assemblied in cover plate 4, bolt group 2 and device body 3 on spring pull bar 1, described device body 3 comprises locking cap 5; Described spring pull bar 1 comprises the screw thread body of rod 11 and the spring body 12 that is attached to the described screw thread body of rod 11 surfaces, and cover plate 4 and bolt group 2 orders are socketed on the described screw thread body of rod 11, with the external screw thread locking on the screw thread body of rod 11, the elasticity tension of control spring body 12; Described locking cap 5 comprises cap body 51 and the body of rod 52 being connected with cap body 51, the internal thread that the built-in and described screw thread body of rod 11 of the described body of rod 52 coordinates; The described screw thread body of rod 11 screws with the body of rod 52 of described locking cap 5.
Further, described cap body 51 comprises four pastes that are evenly distributed.
When work; bolt group is subject to dynamic loading; in long-term work; screw thread fatigue in spring pull bar or bolt group is impaired, causes spring body to be subject to the spring body elastic force disintegrating machine that flies out in when work, and cover plate increases one deck to spring body more and hinders; if spring still can fly out; locking cap will hinder the spring body disintegrating machine that flies out, and unlikely hurting sb.'s feelings, has played safeguard protection effect preferably.
The jaw crusher locking spring safety device that the utility model provides, stops the disintegrating machine locking spring that may fly out by the safety device being arranged on spring pull bar, better and has simply solved the safeguard protection problem of jaw crusher locking spring.
The above, be only specific embodiment of the utility model, but feature of the present utility model is not limited to this, any people who is familiar with this technology is in the utility model field, the variation that can expect easily or modification, all should be encompassed in following claim of the present utility model.
