Abstract
Provided is a resin cartridge filling device for a roadway roof bolt drill hole. The resin cartridge filling device for the roadway roof bolt drill hole is composed of a telescopic tube witch can stretch into the drill hole and a top push rod which is matched with the telescopic tube. The telescopic tube is combined by multi-section casing tubes. The telescopic tube is stretched to needed height according to depth of the roof drill hole, resin cartridge is top-pushed to the deepest position of the drill hole through the telescopic tube inserted into the drill hole and the top push rod matched with the telescopic tube, the resin cartridge is squeezed and stirred upward through the top push rod to bond with drill hole wall a rock stratum, and difficulties that the resin cartridge are hard to place into the drill hole bottom timely and effectively by works due to the fact that the inside of a roof breaks to form a hollow hole or roof net is spread ahead of time are overcome. When the height of a roadway is over 3m, the workers do not need tools such as foot stools and only need to stretch the telescopic tube appropriately according to the height of the roadway, work efficiency is improved, and dangers for the workers existing in the process of filling roof bolt resin cartridge are removed.
Description
Technical field
The utility model relates to a kind of device of casting resin powder stick, especially a kind of be applicable to the back rock stratum than fragmentation and head-room at the device of 3.0 m with upper plate casting resin powder stick.
Background technology
China's coal-mine is used bolt support in beginning in 1956 in rock gangway, so far the history in existing more than 50 year.Bolt support technology has experienced the evolution from low-intensity, high strength to high prestressing force, powerful supporting.The China's coal-mine bolt support is application success in rock gangway at first, and widelys popularize in rock gangway that to have used with " three is little " be the Shotcrete Rockbolt Support Technique of representative.The bolt support sixties of 20th century begins to be applied to mining roadway.Because the heading country rock is soft broken relatively, is subjected to mining influence again, deformation of the surrounding rock in tunnel is big, support technology is required high.Early stage Anchoring Strength of Rock Bolts, the rigidity that adopts of China is low, still belongs to passive protecting on the support principle, and that is that all right is ripe for anchor rod supporting theory, method for designing, support material, construction equipment, monitoring instrument etc. in addition, causes the BOLTING TECHNOLOGY TO COAL ROADWAY slower development.Nineteen ninety, China's state-owned emphasis colliery coal entry anchor rod support only accounts for 3% ~ 5%, and coal roadway support is mainly based on shed ding support.
Up to the present, China's coal-mine has formed coal entry anchor rod support complete set technology system with Chinese characteristics, bolt support become the coal mine roadway first-selection, main support pattern safely and efficiently.But, because when the excavation tunnel, form zone of fracture in the roof strata, the vertical cranny development of top board is more abundant, cause occurring around the hole wall of being everlasting when pinching the plate armature boring cavity among a small circle, this makes and is difficult to it is filled to foot of hole smoothly when the casting resin powder stick; And in some tunnels, running into the situation of beating anchor pole behind the wire lath of spreading earlier sometimes, workman's obstruct owing to wire lath when filling roofbolt resin explosive roll is difficult to powder stick is filled to the boring deep; Moreover the vertical distance of the drift section of some mine is bigger, and the workman is when filling roofbolt powder stick, need be by aids such as high foot rests, need several workmans to cooperatively interact simultaneously and just can finish the filling task, so just reduced operating efficiency, influence the tunnel fltting speed.Above problem has all seriously been run counter to the original intention of the efficient construction of tunnel safety.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, and a kind of device of back armature boring casting resin powder stick of simple to operate, safe and reliable, high efficiency is provided.
For achieving the above object, the device of back armature boring casting resin powder stick of the present utility model constitutes by stretching into the telescoping tube in the boring and the propulsion arm that matches with telescoping tube, and described telescoping tube is formed by the more piece sleeve combination.
The upper port diameter a of described telescoping tube is greater than the diameter c of propulsion arm, and the lower end diameter b of telescoping tube is less than the diameter of boring.
Beneficial effect: the utility model can be when filling top board resin explosive roll, in advance telescoping tube has been inserted in the boring, has solved that the workman is difficult to the timely and effective difficulty of powder stick being sent into foot of hole when forming cavity or top board and shift to an earlier date lapping because of the top board internal fracture; Simultaneously when head-room surpasses 3 m, the workman need not by instruments such as high foot rests, only needing suitably to elongate telescoping tube according to head-room gets final product, reduced the workload of workman's casting resin powder stick like this, improved operating efficiency, the danger that has existed when having eliminated staff's filling roofbolt resin explosive roll.This device is simple to operate, safe and reliable, and the efficient height has practicality and generalization widely.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-propulsion arm, 2-telescoping tube, a-upper port diameter, b-lower port diameter, c-propulsion arm diameter.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The device of back armature boring casting resin powder stick of the present utility model, mainly constitute by stretching into the telescoping tube 2 in the boring and the propulsion arm 1 that matches with telescoping tube 2, described telescoping tube 2 is formed by the more piece sleeve combination, the joint number of sleeve pipe can be determined according to field condition, is 3 joints shown in the figure.The upper port diameter a of described telescoping tube 2 is greater than the diameter c of propulsion arm 1, and the lower end diameter b of telescoping tube 2 is less than the diameter of boring.
The course of work: in the back supporting, according to the top board drilling depth telescoping tube 2 is stretched to desired height, telescoping tube 2 upper port are inserted after the interior segment distance of boring, the lower port of a plurality of resin explosive rolls from telescoping tube 2 is filled in the telescoping tube 2 successively, propulsion arm 1 is inserted telescoping tube 2, by propulsion arm 1 with resin explosive roll along flexible tube wall slowly pushing tow to the bosom of holing, and by upwards extruding of propulsion arm, stir powder stick, make resin explosive roll and drill hole wall rock stratum bonding, afterwards propulsion arm is pulled out in telescoping tube, and telescoping tube is shortened the back from boring, extract out, stir powder stick after inserting anchor pole at last.
Claims (2)
1. the device of a back armature boring casting resin powder stick is characterized in that: it is made of the propulsion arm (1) that can stretch into the telescoping tube (2) in the boring and match with telescoping tube (2), and described telescoping tube (2) is formed by the more piece sleeve combination.
2. the device of back armature boring casting resin powder stick according to claim 1 is characterized in that: the upper port diameter a of described telescoping tube (2) is greater than the diameter c of propulsion arm (1), and the lower end diameter b of telescoping tube (2) is less than the diameter of boring.
