Abstract
The utility model discloses a compound stock body of rod comprises wire aggregate and non -metal casing, and the wire aggregate is the core body of rod, its by many have the deep drawing quality can wires form, the wire uses body of rod central line as the axle, straightly evenly arranges to guarantee the high strength and the extensibility ability of the body of rod, non -metal casing has fire -retardantly and anti -static function, and it is peripheral to arrange it in the wire aggregate to guarantee the wholeness and the security of the body of rod, the non -metal casing surface is equipped with the arch of levogyration structure, with the intensive mixing of guaranteeing resin anchor agent, the violent deformation of country rock can be controlled betterly and adapted to to this stock body of rod to be convenient for coal -winning machine cutting has better popularization prospect.
Description
Technical field
The utility model relates to the anchor rod body in a kind of mine working, relates to the lane side Composite Bolt body of rod that a kind of intensity is higher, have certain elongation per unit length, facilitate coal-winning machine to cut specifically.
Background technology
Along with the increase of underground coal mine mining depth and mining rate, stope drift active workings often show irresistible large deformation feature under huge action of underground.If adopt conventional anchor pole (rope) supporting that intensity is higher, can produce spark when running into reinforced anchor bolt in coal-winning machine coal cutting process, there is the hidden danger of coal dust gas explosion, meanwhile, the useless reinforced anchor bolt cut off is mixed in coal very easily hurts sb.'s feelings and damage equipment.Therefore, usually need manually brushing lateral wall anchor pole in advance during coal mining, not only operate inconvenience, and constrain the performance of working surface production ability.Although glass fibre reinforced plastics rockbolts have hot strength high, the good characteristic such as can to cut, because of glass fiber reinforced plastic this as fragile material, its body of rod shearing resistance, antitorque, flexural strength is lower, and in ore deposit, pressure manifests easy embrittlement in violent tunnel, even brittle failure.A kind of Composite Bolt body of rod of the present invention has that intensity is high, good extending performance, facilitate the advantages such as coal-winning machine cutting, can control and adapt to the drastic deformation of lane side country rock preferably, ensure that coal-face safety successfully advances.
Utility model content
In view of the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of intensity is high, good extending performance, the Composite Bolt body of rod that facilitates coal-winning machine to cut.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Composite Bolt body of rod, is made up of wire aggregate and non-metal shell.Wire aggregate is the core body of rod, its by many have deep drawing quality can wire form, wire, to be straightly evenly arranged for axle with body of rod center line.It is peripheral that non-metal shell is placed in wire aggregate, it has fire-retardant and antistatic property, and certain anti-twisting property need be had, in the making and process of non-metal shell, directly extruded the projection of left-handed spiral configuration on its surface by mould, its scope can adjust according to the anchorage length of anchor pole, to ensure the abundant stirring of resin anchoring agent.
The beneficial effects of the utility model:
This kind of Composite Bolt body of rod, comprise wire aggregate and non-metal shell, wire aggregate is the core body of rod, it is made up of the wire that many have deep drawing quality energy, wire with body of rod center line for axle, straightly to be evenly arranged, to ensure that anchor rod body has higher intensity and good extension property, effectively can control the drastic deformation with suitable for surrounding rock; Non-metal shell has certain anti-twisting property, is placed on wire aggregate peripheral, ensures globality and the torsional property of anchor rod body; Non-metal shell has fire-retardant and antistatic property, and ensure the safety of anchor rod body, meanwhile, non-metal shell is isolated wire aggregate, causes potential safety hazard when avoiding coal-winning machine to cut anchor pole because producing spark; Non-metal shell surface is provided with the projection of left-handed spiral configuration, and its scope can adjust according to the anchorage length of anchor pole, to ensure the abundant stirring of resin anchoring agent, thus ensures that anchor pole can provide enough anchored force.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, more completely can understand the utility model better and easily learn wherein many adjoint advantages, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, wherein:
Fig. 1 is Composite Bolt bar structure schematic diagram.
Fig. 2 is Composite Bolt body of rod radial section figure.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the utility model is described, the Composite Bolt body of rod comprises wire aggregate 1 and non-metal shell 2, wire aggregate 1 is the core body of rod, it is made up of the wire 3 that many have deep drawing quality energy, wire 3 with body of rod center line for axle, straightly to be evenly arranged, to ensure high strength and the extension property of anchor rod body; Non-metal shell 2 has certain anti-twisting property, is placed on wire aggregate 1 peripheral, ensures globality and the torsional property of anchor rod body; Non-metal shell 2 has fire-retardant and antistatic property, and ensure the safety of anchor rod body, meanwhile, non-metal shell 2 pairs of wire aggregates 1 are isolated, and causes potential safety hazard when avoiding coal-winning machine to cut anchor pole because producing spark; Non-metal shell 2 surface is provided with the projection 4 of left-handed spiral configuration, and its scope can adjust according to the anchorage length of anchor pole, to ensure the abundant stirring of resin anchoring agent, thus ensures that anchor pole can provide enough anchored force.
More than to make those of ordinary skill in the art understand the utility model; and to the detailed description that the utility model carries out; but can expect; not departing from the scope that claim of the present utility model contains and can also make other changes and modifications, these changes and amendment are all in protection domain of the present utility model.
