Description
Technical field
The utility model relates to measuring instrument, is specifically related to a kind of mining middle stringcourse extension fixture.
Background technology
In the time that underworkings tunnels, in order to make direction and the position driving that tunnel can be according to the rules, the direction in line traffic control tunnel in general using, utilizes the gradient in stringcourse control tunnel.In the time of the situations such as roadway linking, mistake grade separation, if the locus in tunnel is not controlled well, will cause unnecessary trouble, even affect taking over of workplace, cause huge economic loss.Middle stringcourse is irreplaceable to the impulse in tunnel, but sometimes too many owing to going down the hill on tunnel, on oversize etc. the factor of distance of going down the hill, easily cause middle stringcourse to measure, or the too large problem of measuring error.
At present, down-hole, in the time solving center line and penetrate the situation less than workplace, is all to take unwrapping wire forward, the method for reach infrared transmitter.Constantly reach infrared transmitter, although can reduce the large problem of midline shift error too far causing due to roadway distance, but in the time of the continuous up-and downhill of tunnel, in order to make infrared ray inject workplace, infrared transmitter frequently must move forward, do like this, exist operating process loaded down with trivial details, affect the defect of project progress; In the time solving the problem of stringcourse, the method that down-hole adopts is, find 3 pairs of corresponding stringcourse points by measuring at roadway's sides, when measurement, interconnect with fine rule, afterwards from workplace distance farthest fine rule on tie up a fine rule, draw in workplace, to guarantee that fine rule is just crossing with 3 connecting lines simultaneously, do like this, not only performance difficulty, and due to the Action of Gravity Field of fine rule, along with the increase error of distance also increases thereupon.
In order to solve the above-mentioned defect existing when underworkings tunnels, be necessary to develop a kind of device that mining middle stringcourse extends that is exclusively used in.
Summary of the invention
The purpose of this utility model is to provide a kind of mining middle stringcourse extension fixture.
The utility model is achieved through the following technical solutions:
A kind of mining middle stringcourse extension fixture, comprises support section, regulates part and infrared transmitter, and described support section comprises the anchor pole being fixed on anchor rod pallet board, and the extensible link being connected with anchor pole; Described adjusting portion is divided and is comprised T-shaped support bar, T-shaped support bar is inverted the end that is fixed on extensible link by adjusting screw, the both sides welding roll of T-shaped support bar, on roller, be wound with fine rule, the end of fine rule is fixed on measuring table both sides, the below of described measuring table is fixed with index dial and weight, and infrared transmitter is fixed on the top of measuring table.
Further, one end of described extensible link is welded with the nut matching with anchor pole screw thread, when installation, by nut, anchor pole is connected with extensible link, reaches the object that regulates the direction of T-shaped support bar with maximum angle.
The ultrared center line that described infrared transmitter emits and two fine rules are on same surface level.
When the frequent climb and fall in tunnel, center line is not in time forward when unwrapping wire, the infrared ray workplace of just having no idea to get to, now use step of the present utility model to be: first to regulate extensible link to arrive suitable length, then regulate the direction of T-shaped support bar by adjusting screw, two fine rules are just in time divided into infrared ray after steadily two half, finally regulate the angle of infrared transmitter according to required infrared angle, thereby realize the prolongation of center line; In the time of the climb and fall of tunnel, guide the gradient in tunnel by putting stringcourse, now use step of the present utility model to be: first to regulate extensible link to arrive suitable length, regulate again the direction of T-shaped support bar by adjusting screw, make the infrared ray of infrared transmitter transmitting inject workplace, finally regulate the length of two fine rules according to roadway gradient value, control weight the same with roadway gradient value with the number of degrees that index dial shows, thereby realize the prolongation of stringcourse.
The utility model is simple in structure, easy to carry, measures order of accuarcy high, is adapted to the prolongation of stringcourse in various tunnels, down-hole, simple to operate when use, safe and reliable.
