Abstract
The utility model relates to the technical field of mine drilling apparatus, especially is a dustproof guide sleeve for rotary drill rig, the utility model comprises a guide sleeve, characterized in that, a groove is arranged in an inner hole of the upper end of the guide sleeve, internal threads are arranged at an upper end of the groove, a seal ring, a retaining ring, a seal ring and a nut are in turn arranged in the groove, the nut is an external thread nut with the inner hole, moreover, the thread nut is engaged with the internal thread of the upper end head of the groove. The utility model has characteristics that the guide sleeve not only is acted as the guide sleeve, but also can be dustproof, the previous guide sleeve is disposable and is discarded as useless in deadline, but the guide sleeve of the utility model can exchange the retaining ring to prolong the service life and reduce the cost, the utility model solves the dust hazard of the open-air rotary drill rig and improves the operation environment of the operators.
Description
Technical field
The utility model relates to mine rig technical field, particularly a kind of dustproof guide pin bushing that is used for rotary drill.
Background technology
No matter the present employed rotary drill in China mine is import or homemade rig, and all less than dustproof facilities effectively, dust directly blows on the equipment, influences the use of equipment and supplies, has reduced the application life of equipment and supplies.Infringement to electric fixtures is particularly serious, makes apparatus insulated performance reduce, and causes very big difficulty for the maintenance of equipment.In recent years, I time studied and improved at this kind problem, but failed to reach desirable effect all the time.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the dustproof guide pin bushing that is used for rotary drill of good dustproof effect.
The purpose of this utility model realizes by following technical proposals:
A kind of dustproof guide pin bushing that is used for rotary drill of the present utility model, comprise guide pin bushing, the endoporus that it is characterized in that described guide pin bushing upper end is provided with groove, the upper end of this groove is provided with internal thread, in this groove, be provided with sealing ring, back-up ring, sealing ring and nut successively, this nut is the external screw thread nut that has endoporus, and screw nut is meshed with the internal thread of described groove upper end in addition.
Characteristics of the present utility model are:
1, both plays the effect of guide pin bushing, played the dustproof effect again;
2, can change back-up ring and reach the purpose that increases the service life;
3, simple in structure, cost is low;
4, improve operating personnel's operating environment, reduce environment pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described.
As shown in Figure 1, a kind of dustproof guide pin bushing that is used for rotary drill of the present utility model, comprise guide pin bushing 5, the endoporus that it is characterized in that described guide pin bushing 5 upper ends is provided with groove 2, the upper end of this groove 2 is provided with internal thread, be provided with sealing ring 4, back-up ring 3, sealing ring 4 and nut 1 in this groove 2 successively, this nut 1 is for having the external screw thread nut 1 of endoporus, and screw nut 1 is meshed with the internal thread of described groove 2 upper ends in addition.
Characteristics of the present utility model be this guide pin bushing except the effect that can play guide pin bushing, also can play dustproof effect; Guide pin bushing in the past is disposable, just scrap to the time limit, and this guide pin bushing can be changed back-up ring, reaches the purpose that increases the service life, and has reduced simultaneously cost; Solve the dust harzard of open-air rotary drill, improved operating personnel's operating environment.
