Abstract
A preassemble damping nut roof bolt consists of a roof bolt body, a nut body, a gasket and a salver. A preassemble damping nut is arranged at the tail of the roof bolt body. A pinhole is drilled at the joint section of the damping nut and a screw thread of the roof bolt body and is connected with the damping nut with the roof bolt body through a pinhole. The pinhole at the joint section of the screw thread of the roof bolt body is a through hole or a dead hole. The utility model breaks the traditional manufacturing method for the roof bolt, and directly preassembles the damping nut to the roof bolt body according to a given unsealing torque, making the propulsion of the roof bolt body and the salver tightly fixed and achieve an one-pass operation. The utility model is simple in structure; the nut of the roof bolt body is not easy to lose; the production cost is low and the unsealing torque is relatively stable, which is propitious to the popularization and application of a swift installation technology for the timbering of a laneway roof bolt.
Description
Technical field
The utility model relates to a kind of nut, refers to a kind of prepackage damping nut anchor pole especially.
Background technology
Patent 1 " tunnel resin anchor Fast Installation locknut " (publication number: 2483551, open day: 2002.03.27).With reference to Fig. 1.It is by the platform of six square nuts, 10 tops and is realized driving the rotation of anchor rod body by the shrouding 8 that platform flanging 9 envelopes are pressed, after anchor rod body is solidified by the anchoring agent, the flanging 9 of envelope press seal plate is backed down by the anchor rod body head on this nut platform, then go up jack panel, simplify erection procedure, obviously improved work efficiency.
Patent 2 " anchor pole is installed and used the umbrella shape nut " (publication number: 2415197, the day for announcing: 2001.01.17).Be embedded with plastics damping cover at the nut afterbody, damping cover internal diameter is less than the nut internal diameter, when anchor pole is installed, plastics damping cover withstands anchor rod body in the nut, and nut stirs powder stick with anchor rod body, wait anchor rod body to be solidified after, anchor rod body bursting damping cover, nut precession supporting thing is fixed.But above-mentioned patented technology still has the following disadvantages:
1, the structure more complicated of above-mentioned patent, production technology acquires a certain degree of difficulty, and material cost and processing cost are higher.
2, open the moment of torsion instability, can not effectively it be opened torque value and be controlled in the technical requirements scope, finally influence installation quality and speed.
3, the nut and the body of rod are not one, lose easily, cause waste of material.
The utility model content
It is a kind of simple in structure that the purpose of this utility model will provide exactly, and processing technology is simple, and it is relatively stable to open moment of torsion, and damping nut and body of rod prepackage are one, improve the prepackage damping nut anchor pole of installation efficiency.
For achieving the above object, the utility model adopts following technical scheme: prepackage damping nut anchor pole comprises that the body of rod, nut body, packing ring, pallet, body of rod afterbody are processed with screw thread, nut body is polygon, and the middle part is an internal thread hole, at the body of rod afterbody damping nut is housed in advance; The damping nut is to be made of nut body, pin-and-hole and pin.On the plane parallel with the nut body axis, pin-and-hole that communicates with internal thread hole and the pin that cooperates with pin-and-hole are arranged, also have and pin-and-hole concentric and isometrical pin-and-hole at body of rod afterbody, and cooperate with pin.On the plane parallel with the nut body axis, the pin that has a pin-and-hole that communicates with internal thread hole at least and cooperate with pin-and-hole, body of rod afterbody circumference have at least one with pin-and-hole concentric and pin-and-hole isometrical and that cooperate with pin.Pin-and-hole on the body of rod afterbody is blind hole or through hole.
In process of production, be contained in pallet, packing ring and damping nut on the anchor pole in order at the anchor rod body thread segment in advance, perhaps only the damping nut is contained in the anchor rod body tail end in advance, and pin is pressed into pin-and-hole with punch press or forcing press, pin is controlled in the technical requirements scope unlatching moment of torsion of damping nut and anchor pole in the body of rod.
The damping nut is contained in when dispatching from the factory on the anchor rod body in advance, and after the body of rod inserted petrosal foramen, its front end stirred the anchoring agent in rotation, during rotation because the moment of torsion of the body of rod less than the unlatching moment of torsion between damping nut and the anchor pole, therefore, the damping nut can drive body of rod rotation; After the anchoring agent was solidified, the body of rod can not rotate, and the damping nut is cut off the pin that connects with the body of rod under the drive of rig, thereby overcame the unlatching moment of torsion between the damping nut and the body of rod, make the damping nut along hand of spiral forward precession pallet is fastened on the crag.
The utility model is simple in structure, and cost of production is lower, and processing technology is simple, and the body of rod and damping nut combine as a whole, and is difficult for losing, and it is relatively stable to open moment of torsion, can control and open moment of torsion in the otherwise effective technique scope, obviously improves installation efficiency.

Specific embodiments
With reference to Fig. 2, Fig. 3, Fig. 4.Damping nut anchor pole comprises the body of rod 5, nut body 7, packing ring 4, pallet 3, and body of rod afterbody is processed with screw thread, and nut body is polygon and the centre is internal thread hole.Be connected with damping nut 1 at body of rod afterbody.Damping nut 1 is by nut body 7, pin-and-hole 6 and sells 2 and constitute on the plane parallel with nut body 7 axis, pin-and-hole 6 that communicates with internal thread hole and the pin 2 that cooperates with pin-and-hole are arranged.On the plane parallel with nut body 7 axis, the pin 2 that has a pin-and-hole that communicates with screwed hole 6 at least and cooperate with pin-and-hole.Body of rod afterbody have at least one with pin-and-hole 6 concentrics and isometrical pin-and-hole 8, and cooperate with pin 2.
In process of production, will sell 2 by punching machine or forcing press and be pressed into pin-and-hole 6 and pin-and-hole 8, the damping nut is joined together with the body of rod 5 in advance.
