Description

Technical Field

[0001] This utility model relates to the field of anchor cable stress sensor technology, specifically an anchor cable stress sensor that is easy to connect and fix. Background Technology

[0002] The intrinsically safe anchor bolt (cable) stress sensor for mining is an automated monitoring device integrating microcomputer and computer technology that automatically measures and transmits the stress changes of anchor bolts and cables in underground coal mines. When the internal stress of the anchor bolt (cable) changes, the anchor bolt (cable) sensor head transmits the collected stress value to the sensor body in real time. The sensor body outputs the received data to the microcontroller circuit. The microcontroller circuit processes the collected signal and transmits it to the underground data acquisition substation. The data acquisition substation then transmits the data to the main equipment above ground via cable, realizing the above-ground monitoring of the stress changes of the underground anchor bolt (cable). It is an indispensable monitoring instrument for studying the stability of roadways and tunnels. When installing the stress sensor, it is necessary to align it with the axis of the anchor bolt to improve measurement accuracy.

[0003] Before installing the stress sensor, a backing plate needs to be fabricated. The backing plate must be made of thick steel plate, thick enough to prevent the anchor cable gauge from deforming during operation. Two layers are used, with a small triangular pad welded in between, at the same angle as the horizontal plane of the anchor cable. This is used to adjust the angle, ensuring the anchor cable gauge is aligned with the anchor cable axis after installation. The small triangular pad requires high-precision cutting, and welding errors can easily lead to angular deviations, making installation somewhat complicated. Therefore, an anchor cable stress sensor that is easy to connect and fix is ​​needed. Utility Model Content

A transmission line is installed on the middle of the outer side of the sensor body. The base plate is installed below the sensor body, and a high-strength shaft is installed on the left side of the base plate. A rotating plate is installed below the high-strength shaft, and the rotating plate is rotatably connected to the high-strength shaft. The rotating plate changes its angle by rotating the high-strength shaft, thereby aligning the axis of the sensor body with the axis of the anchor bolt, making the data measured by the sensor body more accurate.

[0006] Furthermore, a slide rail is installed inside the rotary plate, and the slide rail is slidably connected to the rotary plate.

[0007] Furthermore, a wedge is installed above the slide rail, and the wedge is welded to the slide rail. The movement of the wedge will push the rotating plate, and the rotating plate will change its angle by rotating through a high-strength shaft.

[0008] Furthermore, a stud is installed in the middle of the right side of the rotary plate, and the stud is rotatably connected to the rotary plate. Rotating the stud causes two slide rails to slide in the rotary plate.

[0009] Furthermore, the stud is threaded with a nut, and a washer is installed on one side of the nut. The two nuts clamp the stud and the slide rail connection through the washer to prevent loosening that could cause the wedge to move and change its angle.

[0010] Furthermore, a top pad is installed on the top of the sensor body, and positioning components are installed on the upper and lower sides of the outer side of the sensor body.

[0011] Furthermore, the positioning component includes a pulley and a side frame, and the pulley is rotatably connected to the periphery of the side frame. The pulley on the side frame rolls on the sensor body, which facilitates embedding.

[0012] Furthermore, the positioning assembly also includes a slide bar group and a spring. One end of the side frame is slidably connected to the slide bar group, and a spring is installed around the slide bar group. The spring pushes the pulley against the surface of the sensor body through the side frame.

[0020] like Figure 1 and Figure 2 As shown, an anchor cable stress sensor that is easy to connect and fix includes a sensor body 1 and a base plate 3. A transmission line 2 is installed on the outer center of the sensor body 1. The base plate 3 is installed below the sensor body 1, and a high-strength shaft 4 is installed on the left side of the base plate 3. A rotating plate 5 is installed below the high-strength shaft 4 and is rotatably connected to the high-strength shaft 4. A slide rail 6 is installed inside the rotating plate 5 and is slidably connected to the rotating plate 5. A wedge 7 is installed above the slide rail 6 and is welded to the slide rail 6. A [missing information - likely a component or material] is installed on the right center of the rotating plate 5. The stud 8 is rotatably connected to the rotating plate 5. The stud 8 is threaded with a nut 9, and a washer 10 is installed on one side of the nut 9. Rotating the stud 8 causes the two slide rails 6 to slide in the rotating plate 5. The wedge block 7 moves and pushes the rotating plate 5. The rotating plate 5 rotates and changes its angle through the high-strength shaft 4, thereby aligning the axis of the sensor body 1 with the axis of the anchor rod. The data measured by the sensor body 1 is more accurate. The two nuts 9 clamp the connection between the stud 8 and the slide rail 6 through the washer 10 to prevent loosening that would cause the wedge block 7 to move and change its angle, making the installation more stable.

[0021] like Figure 1 and Figure 3As shown, a top pad 11 is installed on the top of the sensor body 1, and positioning components 12 are installed on the upper and lower sides of the outer side of the sensor body 1. The positioning components 12 include pulleys 1201 and side frames 1202, and the pulleys 1201 are rotatably connected to the side frames 1202. The positioning components 12 also include a sliding rod group 1203 and a spring 1204. One end of the side frame 1202 is slidably connected to the sliding rod group 1203, and the sliding rod group 1203 is equipped with a spring 1204. The bottom pad 3 and the top pad 11 are embedded into the two ends of the sensor body 1. The pulleys 1201 on the side frames 1202 roll on the sensor body 1 for easy embedding. The side frames 1202 slide on the sliding rod group 1203. The spring 1204 pushes the pulleys 1201 against the surface of the sensor body 1 through the side frames 1202. The four sets of positioning components 12 facilitate the installation and fixation of the bottom pad 3 and the top pad 11, and align the axes, so that the sensor body 1 bears more even force.

[0022] Working principle: When using this anchor cable stress sensor that is easy to connect and fix, firstly, the bottom plate 3 and the top plate 11 are embedded into both ends of the sensor body 1. The pulley 1201 on the side frame 1202 rolls on the sensor body 1 for easy embedding. The side frame 1202 slides on the slide bar group 1203. The spring 1204 pushes the pulley 1201 against the surface of the sensor body 1 through the side frame 1202. The four sets of positioning components 12 facilitate the installation and fixation of the bottom plate 3 and the top plate 11 and align the axis. The sensor body 1 bears more even force. The rotating stud 8 drives the two slide rails 6 to slide in the rotating plate 5. The wedge 7 moves and pushes the rotating plate 5. The rotating plate 5 changes the angle through the high-strength shaft 4, thereby aligning the axis of the sensor body 1 with the anchor bolt axis. The data measured by the sensor body 1 is more accurate. The two nuts 9 clamp the connection between the stud 8 and the slide rail 6 through the washer 10 to prevent loosening that would cause the wedge 7 to move and change the angle, making the installation more stable.
