Description

The disrumpent feelings avalanche protector of a kind of coal road shoulder nest anchor pole end tail

Technical field

The utility model relates to the disrumpent feelings avalanche protector of a kind of coal road shoulder nest anchor pole end tail.

Background technology

During coal road driving, ore deposit is pressed and is manifested strongly, and gross distortion occurs in tunnel, and bolt support becomes technological difficulties of tunnel speedy drivage.At present coal road driving adopts bolt supports, and shoulder nest place anchor pole mostly is to tilt to set, through coal side and be anchored in top board.If there is Design of bolt support unreasonable structure, geological structure, many-sided reasons such as supporting material is defective, under the impact of tunnelling, often can there is disrumpent feelings failure phenomenon in shoulder nest place anchor pole, in the time of disrumpent feelings, cause the disrumpent feelings avalanche of part anchor pole end tail, the anchor pole end tail of avalanche collapses along parabolic path, bring certain potential safety hazard to engineering construction personnel, even if carry out technological improvement and perfect on design of its support, can not guarantee not occur the accident of the disrumpent feelings avalanche of anchor pole end tail completely, at present, coal road driving workman utilizes the method for tied silk bundle system that anchor pole end tail is fixed on wire lath around, when the avalanche of anchor pole end tail, utilize the pulling force of tied silk control disrumpent feelings anchor pole end tail collapse, this method has played protective action to a certain extent, but have the following disadvantages: 1. easily take off mouth and there will be and shake off casualty accident in the not enough situation of pulling force of tied silk, 2. troublesome poeration, the tied silk inadequate standard of constructing, 3. waste resource, is unfavorable for recycling etc.Therefore under rational design of its support prerequisite, take safe and effective, standard is energy-conservation, the safeguard procedures of simple operation are very necessary.

Utility model content

Technical problem to be solved in the utility model is to provide the disrumpent feelings avalanche protector of a kind of coal road shoulder nest anchor pole end tail.

For achieving the above object, the utility model provides following technical scheme: the disrumpent feelings avalanche protector of a kind of coal road shoulder nest anchor pole end tail.Comprise that a kind of periphery is connected snap close with the built-in screwed hole steel ring of four small sircle holes and a plurality of two ends with the steel wire of rotatable snap close.Described periphery is with the thick 8-10mm of built-in screw thread steel ring of a plurality of small sircle holes, diameter 150mm, steel ring center has the built-in screwed hole mating with anchor pole, the small sircle hole of four internal diameter 10-12mm is evenly left in steel ring neighboring, steel wire connection snap close is furnished with rotatable connection snap close by the steel wire two ends of long 400mm some strength and forms, connect snap close and daily key chain function class used seemingly, so, form the disrumpent feelings avalanche protector of a kind of coal road shoulder nest anchor pole end tail.

When coal road driving installs shoulder nest anchor pole, screw at the anchor pole end tail place built-in screwed hole steel ring of the peripheral band small sircle hole that matches, steel wire connects the periphery small sircle hole that snap close one end is connected to built-in screwed hole steel ring, one end is connected to the anchor pole fixtures such as wire lath around, when there is disrumpent feelings avalanche in anchor pole end tail, by the disrumpent feelings end tail of fixed constraint power restriction anchor pole of fixture collapse, play the effect that the disrumpent feelings avalanche of anti-shoulder protector nest anchor pole end tail is hurted sb.'s feelings; Material can reuse, standard simple to operate.Saving material cost can be reached like this, the working environment of safety standard can be provided for coal miner again.

The coal road that should be connected snap close with the steel wire that matches with built-in screwed hole steel rings of a plurality of small sircle holes is takeed on the feature that the disrumpent feelings avalanche protector of nest anchor pole end tail has simple operation standard, simple and practical, reusable edible, can effectively prevent from takeing on nest anchor pole end tail avalanche casualty accident.

The specific embodiment

Below in conjunction with accompanying drawing, the description by embodiment, is described further the utility model:

Coal road shoulder nest anchor pole front view as shown in Figure 1, it shown in Fig. 2, is the built-in screwed hole steel ring front view of peripheral band small sircle hole, Fig. 3 is the front view that steel wire connects snap close, and the rotatable lock buckle at its two ends is similar to common key snap close, and Fig. 4 is schematic diagram of the present utility model, the built-in screwed hole steel ring 7 that the utility model comprises peripheral band small sircle hole 5 and two ends are connected snap close 9 with the steel wire of rotatable snap close 8, the built-in screwed hole steel ring 7 of described peripheral band small sircle hole 5 is at thickness 8-10mm, a built-in screwed hole 6 matching with coal road shoulder nest anchor pole end tail screw thread is opened in the common steel ring center of diameter 150mm, at steel ring periphery place, evenly open the small sircle hole 5 of four diameter 10-12mm, periphery small sircle hole 5 is connected to one end that steel wire connects snap close 9, the other end that steel wire connects snap close 9 is connected to shoulder nest anchor pole 1 after the installation fixture such as wire lath around, so, form the disrumpent feelings avalanche protector 10 of a kind of coal road shoulder nest anchor pole end tail.

When coal road tunnels, after coal road shoulder nest place anchor pole 1 installs, screw at its end tail 4 places built-in screwed hole steel ring 7 of peripheral band small sircle hole 5, be close to rigging 3, with steel wire, connect snap close 9 one end and be rotatably connected the periphery small sircle hole 5 that snap close 8 is connected to built-in screwed hole steel ring 7, the other end is connected to skyhook 1 fixtures such as wire lath around, utilize the avalanche of the disrumpent feelings anchor pole of restraint forces restriction end tail of fixture, ensure constructor's personal safety, this protector 10 standard simple to operate, can reuse and reclaim, can reach saving material cost like this, can provide for coal miner the working environment of safety standard again.

Adopt technique scheme, the disrumpent feelings avalanche protector of a kind of coal road shoulder nest anchor pole end tail, comprise that a kind of periphery is connected snap close with the built-in screwed hole steel ring of four small sircle holes with a plurality of steel wires that are rotatably connected snap close with two ends, be ready to use in coal mine lower time, after coal road shoulder nest place rockbolt installation is good, the built-in screwed hole steel ring of screwing on, the rotatable snap close in one end of steel wire connection snap close is connected to the periphery small sircle hole of built-in screwed hole steel ring, the other end is connected to the skyhook fixtures such as wire lath around, when in tunnelling process there is the disrumpent feelings avalanche of end tail in anchor pole, steel wire connects the fixed constraint power restriction anchor pole end tail avalanche that snap close utilizes fixture, play the effect that the disrumpent feelings avalanche of anti-shoulder protector nest anchor pole end tail is hurted sb.'s feelings.The disrumpent feelings avalanche protector of this coal road shoulder nest anchor pole end tail has that installation specification is convenient, simple and practical, the feature of recoverable, can be colliery and saves material cost, and the working environment of safety standard can be well provided for underground operators.

Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
