Roof bolter angle adjusting and supporting device and using method thereof

Abstract

The invention discloses a roof bolter angle adjusting and supporting device and a using method thereof. The device comprises a telescopic stand column, an angle scale and a roof bolter sleeve, whereinthe angle scale is of a 90-degree fan-shaped frame structure, and is fixedly connected to the telescopic stand column; scales are arranged on the arc-shaped edge of the angle scale; the tail end of the roof bolter sleeve is sealed, the upper middle portion of the roof bolter sleeve is fixedly connected with a rotating shaft, the rotating shaft is rotationally connected to corners of two right-angle sides of the angle scale, the tail end of the roof bolter sleeve is fixedly connected to an angle-adjusting guide arc-shaped through hole formed in the arc-shaped side of the angle scale through bolts, and the radial circle center of the angle-adjusting guide arc-shaped through hole coincides with the axis of the rotating shaft. The angle of the roof bolter can be adjusted; stepless adjustmentof the angle is achieved, installation is stable and reliable, the stand column is telescopic, so that the occupied roadway space is small, operation is convenient, the device further has the advantages of being simple in structure, reasonable in design, stable and reliable, the problem that anchor rod (cable) holes of construction side parts and bottom plates are difficult to construct can be effectively solved, the anchor rod (cable) construction efficiency is improved, and the labor intensity of workers is reduced.

Problems solved by technology

[0002] With the gradual extension of coal mining to the deep, the pressure of coal mine roadways is more obvious, and the use of passive support can no longer meet the needs of mine safety production. Therefore, the active support method of bolts (cables) must become the main support method of roadways; roadway When constructing the bolt (cable) hole inside, the bolt (cable) should be perpendicular to the outline of the shaft roadway. Due to the influence of the construction site conditions, construction technology and the structure of the bolter machine, the bolter machine cannot construct the roadway side and the bottom plate bolt hole. , and the anchor (cable) hole angle construction is not accurate, it is difficult to meet the engineering design requirements, which seriously affects the quality of the roadway project, and greatly restricts the use of the roadway side and floor bolt (cable) support, and the Chinese patent application (Application No. 201820153152.9) discloses a special bracket for anchor cable construction, specifically disclosing a semi-circular ring, a bolter fixing plate, a sleeve and a jack. The semi-circular ring is fixedly connected to the workbench, and the sleeve is connected to the semi-circular The bolter fixed plate is fixedly connected with the casing, the tail end is hinged on the worktable, and the two ends of the jack are respectively hinged to the bolter fixed plate and the worktable. This method is due to the existence of the jack. It will play a restrictive role in the rotation process of the fixed plate of the bolter, and the telescopic length is limited, so there must be a problem of limited angle adjustment, and it is fixed on the workbench, which takes up a lot of space and is inconvenient to transport. The jack has an elastic buffer effect, Vibration occurs under the action of the bolter, which will lead to inaccuracy when drilling; due to the limitations of the workbench and jack, it is difficult for the device to construct the side anchor hole and the bottom anchor hole. In addition, the structure and process of the device are complicated, which is inconvenient for on-site workers. operation and use
