Abstract
The invention discloses an anti-collision part bolt for drawing a mine car. The anti-collision part bolt comprises a draw bolt body, wherein one end of the draw bolt body is arranged in an anti-collision part, double nuts are arranged at the other end of the draw bolt body, a locking nut is arranged at the end, away from a screw cap, of the draw bolt body, and the portion, between the locking nut and the double nuts, of the draw bolt body is sleeved with a compression spring. The anti-collision part bolt for drawing the mine car is simple in structure, reasonable in design and reliable in connection, the problem of unhooking of the mine car caused by loosening and releasing of the double nuts in long-term use is solved, the service life of a mine car drawing device is prolonged greatly, production efficiency is improved, safety production is effectively guaranteed, and personal safety of underground workers is further guaranteed.
Description
Technical field
The present invention relates to mining car haul device field, relate in particular to a kind of car haul bolt of meeting and discussing.
Background technique
Between mine car, collide or be pulled in process, when buffer spring assembling, leave decrement, by compression or the momentary action power lower nut stretched of traction and the junction plane of hook housing must there is certain distance, and draw bolt and nut are coarse thread, because the two screw thread junction plane fit tolerance is larger, also there is certain gap.Cotter pin is in use often because following two kinds of factors are damaged: 1, tunnel moisture corrosion; 2, the impulsive load that produces makes nut frequently accept impact endurance test shock locomotive haulage mine car moment, nut can along the screw thread on draw bolt gradually the loosening axial float that produces its cut-out is made.After cotter pin is destroyed, time is once long double nut loosening and releasing, locomotive haulage power mainly passes to mine car by the thread joint face of draw bolt and double nut again, therefore when double nut is threaded off after landing from draw bolt, whole traction delivery system will be destroyed, must cause mine car to break off relations and security incident occurs, affecting carrying out in order of underground transportation production.In order to prevent the generation of similar hazard event, the safety coefficient while improving mine car operation, must arrange a kind of safe and reliable anti-thread-releasing device and solve this problem.Therefore,, for addressing the above problem, spy provides a kind of new technological scheme.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: proposed a kind of car haul bolt of meeting and discussing.
Technical solution of the present invention is achieved in that a kind of car haul bolt of meeting and discussing, comprise draw bolt, in one end of described draw bolt is arranged on and meets and discusses, double nut is set on the other end, on described draw bolt, be also provided with locking nut away from nut one end, on the draw bolt between described locking nut and double nut, cover has holddown spring.
As preferably, on described draw bolt away from being also provided with cotter pin on nut one end.
As preferably, described holddown spring and draw bolt are coaxially arranged.
As preferably, the two ends of described holddown spring are plane.
As preferably, described holddown spring is that spring steel is made.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The car haul of the present invention bolt of meeting and discussing, simple in structure, reasonable in design, the invention solves double nut uses the loosening and releasing causing for a long time and causes mine car unhook problem, improve greatly the working life of car haul device, improved manufacturing efficiency, effectively ensured safety in production, meanwhile, underground labour's life is further ensured safely.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is mounting structure schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
In figure: 1. meet and discuss; 2. draw bolt; 3. end support; 4. spring; 5. hook housing; 6. double nut; 7. holddown spring; 8. locking nut; 9. cotter pin.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Refer to Fig. 1 and Fig. 2, a kind of car haul bolt of meeting and discussing, comprise draw bolt 2, one end of described draw bolt 2 is arranged on meets and discusses in 1, and double nut 6 is set on the other end, on described draw bolt 2, be also provided with locking nut 8 away from nut one end, on draw bolt 2 between described locking nut 8 and double nut 6, cover has holddown spring 7, and described holddown spring 7 is coaxially arranged with draw bolt 2, in the time that reality is used, the two ends of described holddown spring 7 are plane, and described holddown spring 7 is made for spring steel.On described draw bolt 2, away from being also provided with cotter pin 9 on nut one end, can further stop coming off of locking spring 8.
Its embodiment is: when use, draw bolt 2 is arranged on end support 3 by spring 4 and hook housing 5.Now holddown spring 7 can produce between the screw thread that pretightening force makes locking nut 8, double nut 6 and draw bolt 2 and produce impacting force, can effectively stop that locking nut 8 and double nut 6, because of loosening, play occurs, therefore double nut 6 just there will not be dropout phenomenon.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
