[0021] Reliable limit setting enhances device stability.

[0022] The limiting structure consists of a limiting chamber, a worm gear, a worm, a limiting screw, and a friction block. Rotating the limiting knob drives the limiting screw to approach the telescopic inner column through the worm and worm gear. The friction block then passes through the circular through-hole on one side of the limiting chamber and the telescopic outer column, squeezing the telescopic inner column. The friction force stabilizes the telescopic inner column, solving the shortcomings of existing positioning devices in limiting the telescopic column, enhancing the stability of the device during use, and improving measurement accuracy.

[0036] The working principle of the anchor support positioning device is as follows:

[0037] Overall structure building and initial state:

[0038] When the device is installed in the underground roadway, first, the base plate 1 with a plurality of support columns 2 is placed in a suitable position and fixed, the support column 2 is connected with the top plate 3 at the top, forming a basic frame, at this time, the telescopic inner column 5 is inside the telescopic outer column 6, in the initial state of telescopic, the anchor rod 7 passes through the circular through hole of the base plate 1 and the top plate 3, one end is threadedly connected with the hook 8, the adjusting structure and the limiting structure are in standby state;

[0039] Adjusting the position of the telescopic column:

[0040] When the telescopic column needs to be adjusted to adapt to different measurement scenes, the worker rotates the adjusting knob 20, which drives the adjusting screw 11 to rotate. Since the adjusting screw 11 is screw-connected with the center of the slide column 10, the slide column 10 slides in the square slide groove 9 inside the bottom plate 1. The two ends of the slide column 10 are rotationally connected with the bottom of the telescopic outer column 6, so the movement of the slide column 10 drives the telescopic outer column 6 to move in the first slide groove 4 on the top of the bottom plate 1, thereby adjusting the relative position of the telescopic outer column 6 and the telescopic inner column 5. When the adjustment is appropriate, stop rotating the adjusting knob 20;

[0041] Limiting telescopic column:

[0042] After adjusting the telescopic column to the appropriate position, in order to ensure its stability, limiting is needed. The worker rotates the limiting knob 21, which drives the worm 14 to rotate. Since the worm 14 is meshingly connected with the worm gears 13 in the two limiting warehouses 12, the rotation of the worm 14 drives the worm gears 13 to rotate. The worm gears 13 are screw-connected with the limiting screws 15 at the shaft centers. Since the inner wall of the limiting warehouse 12 is provided with external splines and the outer wall of the limiting screw 15 is provided with internal splines, the external splines slide inside the internal splines. The design of the internal splines and the external splines makes the limiting screw 15 not rotate with the rotation of the worm gears 13. The limiting screw 15 will only slide along the external splines provided on the inner wall of the limiting warehouse 12. Therefore, when the worm gears 13 rotate, the worm gears 13 will drive the limiting screw 15 to move close to the telescopic inner column 5. The side of the limiting warehouse 12 and the telescopic outer column 6 that are close to each other are both provided with a circular through hole through which the friction block 16 passes. The friction block 16 passes through the circular through hole and presses the telescopic inner column 5 with the movement of the limiting screw 15. The telescopic inner column 5 is fixed by using friction force to prevent it from moving during use, thereby enhancing the stability of the device.

[0043] Anchor rod 7 positioning: The stable telescopic inner column 5, telescopic outer column 6, and support column 2 jointly constitute a triangular stable structure, which provides stable support for the anchor rod 7, prevents the anchor rod 7 from being skewed and deviating in position during use, and ensures the accurate positioning of the anchor rod 7.

[0044] Hook 8 use:

[0045] First step: left help hook 8 hang pull ring: in the coal mine roadway deformation monitoring, the staff hand-held tape, walk to the left help installation anchor support positioning device position, the pull ring head of the tape is aimed at the hook 8 hook body 17 threaded connection on the one end of anchor rod 7, because the hook body 17 is close to the side of the blocking column 19 is provided with a groove, when there is no external interference, the torque spring 18 will be through the elastic force of blocking column 19 is limited in the groove on the side of the hook body 17, at this time, the staff need to use fingers gently press the blocking column 19, make it overcome the elastic force of torque spring 18, get out of the groove, open the opening of the hook body 17, the pull ring is successfully hung in the hook body 17, then release the blocking column 19, the blocking column 19 is under the action of torque spring 18 back to the groove position, card the pull ring, prevent it from falling off;

[0046] Second step: pull the tape to the right help: keep the left help pull ring and hook 8 connection stable, the staff slowly pull the tape, make the measuring tape of the tape gradually stretch, move to the direction of the right help installation anchor support positioning device, in the process of pulling, pay attention to avoid the measuring tape of the tape and other objects in the underground roadway winding, friction, ensure that the measuring tape can be smoothly pulled out;

[0047] Third step: right help hook 8 hang tape shell: after reaching the right help, the tape shell is aimed at the hook 8 on the anchor rod 7 of the right help, press the blocking column 19 with fingers, open the opening of the hook body 17, hang the tape shell on the hook body 17 at the appropriate position, release the blocking column 19 to complete the fixation, at this time, the tape is stably erected between the left help and the right help, realize single person convenient measurement, improve the measurement efficiency.
