The telescopic boom for the underground explosive loading truck has the advantages of being simple and compact in structure, stable in operation, and durable.
Description
Technical field
The utility model relates to a kind of mine operation mechanical field, relates in particular to a kind of telescopic arm for underground explosive loading truck.
Background technology
At present, the underground explosive loading truck that domestic mine operation uses, uses telescopic arm that flexible pipe is delivered to big gun hole place.The telescopic arm now using is made up of inner arm and outer arm, for reducing the resistance of motion, is generally, in inner arm outside and outer arm inner side, nylon block is installed, and to reduce the contact surface of inner arm and outer arm, and then reduces the resistance of motion.But owing to being take nylon block as contact surface,, there is the open defects such as frictional resistance is large, vibration is large, nylon block replacing is frequent in the friction between inner arm and outer arm or sliding friction.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, operate steadily, the long-lived telescopic arm for underground explosive loading truck.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is:
A kind of telescopic arm for underground explosive loading truck, comprise outer arm, inner arm and oil cylinder, described inner arm is sheathed in outer arm, described inner arm relative outer arm under the driving of oil cylinder does stretching motion, the telescopic mouth place of described outer arm is provided with more than one roll shaft, described outer arm is provided with and the rubber pad of inner arm Surface Contact near the inner side of telescopic mouth one end, described inner arm away from the surface of telescopic mouth one end be provided with outer arm in the friction pad of side contacts.
Further improvement as technique scheme:
Described rubber pad is identical with friction pad thickness.
Described roll shaft is two, and the telescopic mouth place of described outer arm is provided with fixed mount, and described roll shaft is installed on fixed mount.
Described oil cylinder comprises cylinder tube and cylinder rod, and described cylinder rod is sheathed in cylinder tube and relative cylinder tube does stretching motion, and described inner arm is hollow, and described cylinder tube is articulated with in outer arm, and described cylinder rod is articulated with in inner arm.
The telescopic mouth place of described cylinder tube is provided with the wear-resistant pad of avoiding cylinder tube and interior arm contact.
Compared with prior art, the utility model has the advantage of:
Telescopic arm for underground explosive loading truck of the present utility model, the telescopic mouth place of outer arm is provided with more than one roll shaft, inner arm is in the time of stretching motion, roll shaft is at inner arm surface straight-line rolling, between outer arm and inner arm, be provided with rubber pad and friction pad, outer arm is not contacted with inner arm, the friction of outer arm and inner arm is become to rolling friction from sliding friction, greatly reduced resistance and wearing and tearing when inner arm is flexible.The utility model is also provided with wear-resistant pad, in the time that cylinder rod drives inner arm to do stretching motion, inner arm does not directly contact each other with cylinder tube, reduce resistance, and limit position mutual between inner arm and cylinder tube, guarantee can not produce skew and vibration in inner arm telescopic process, operate steadily, reliably.The utility model is simple in structure, operate steadily, and increased the application life of outer arm, inner arm and cylinder tube.

The specific embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is further described.
As shown in Figures 1 to 4, the telescopic arm for underground explosive loading truck of the present utility model, comprises outer arm 1, inner arm 2 and oil cylinder, and outer arm 1 is fixed on the support of underground explosive loading truck, and inner arm 2 is sheathed in outer arm 1.Oil cylinder comprises cylinder tube 3 and cylinder rod 6, cylinder rod 6 is sheathed in cylinder tube 3, and inner arm 2 is hollow, and cylinder tube 3 fixed covers are located in outer arm 1, cylinder rod 6 is fixed in inner arm 2, and the relative cylinder tube 3 of cylinder rod 6 does stretching motion and drives the relative outer arm 1 of inner arm 2 to do stretching motion.The telescopic mouth place of outer arm 1 is provided with more than one roll shaft 9, outer arm 1 is provided with and the rubber pad 8 of inner arm 2 Surface Contacts near the inner side of telescopic mouth one end, inner arm 2 is provided with and the friction pad 5 of outer arm 1 interior side contacts away from the surface of telescopic mouth one end, in the utility model, rubber pad 8 is identical with friction pad 5 thickness, outer arm 1 is not contacted with inner arm 2, when inner arm 2 does stretching motion, roll shaft 9 is straight-line rolling on inner arm 2 surfaces, make outer arm 1 and the friction of inner arm 2 become rolling friction from sliding friction, resistance and wearing and tearing when inner arm 2 is flexible are greatly reduced, increase the application life of outer arm 1 and inner arm 2.
In the present embodiment, roll shaft 9 is two, and the telescopic mouth place of outer arm 1 is provided with fixed mount 4, and roll shaft 9 is all installed on fixed mount 4, can in inner arm 2 stretching motions, play guide effect.
In the present embodiment, the telescopic mouth place of cylinder tube 3 is provided with the wear-resistant pad 7 with inner arm 2 interior side contacts, and wear-resistant pad 7 can avoid cylinder tube 3 to contact with inner arm 2.Rubber pad 8, friction pad 5 and wear-resistant pad 7 directly do not contact outer arm 1, inner arm 2, cylinder tube 3 each other, in the time that inner arm 2 does stretching motion, reduce resistance, and because rubber pad 8, friction pad 5 and wear-resistant pad 7 have limited mutual position between outer arm 1 and inner arm 2, inner arm 2 and cylinder tube 3, guarantee that inner arm 2 can not produce skew and vibration in telescopic process, improved traveling comfort and reliability.
Although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
