Description

Technical Field

[0001] This utility model belongs to the technical field of mining surveying equipment, specifically relating to an electronically displayed roof separation instrument. Background Technology

[0002] In mining and tunnel engineering, roof delamination meters are crucial equipment for monitoring the stability of tunnel roofs and are widely used in safety monitoring of various underground projects. Currently, the industry commonly uses manual observation to obtain roof delamination data, that is, manually reading the scale of the delamination meter installed at the top of the tunnel to determine roof changes.

[0003] Currently, the use of roof separation instruments is hampered by poor lighting conditions, making observation and operation inconvenient. These instruments are installed high up in the tunnel roof, requiring long-distance observation using binoculars or close-up viewing via ladders, making the process cumbersome, especially in narrow or complex tunnel environments. Furthermore, operators face the risk of falls from height when using ladders for observation, and temporary elevated work within the tunnel is susceptible to interference from passing equipment or personnel, increasing the probability of accidents.

[0004] Moreover, the data from the roof separation instrument mainly relies on the subjective readings and records of the staff, which are prone to deviation due to human factors such as visual errors and record-keeping negligence, thus affecting the accuracy of the judgment on roof stability. Utility Model Content

[0005] This invention provides an electronically displayed roof delamination meter to solve the problems of difficulty in observation, inaccurate observation data, and high safety risks for staff during observation using existing roof delamination meters.

[0006] The technical solution of this utility model is: an electronic display top plate delamination instrument, including a tray base, a plurality of anchor rods on the top of the tray base, an outer rod on the bottom of the tray base, an inner rod inside the outer rod, a displacement sensor between the outer rod and the inner rod, a host computer connected to the displacement sensor, and scales on both the outer rod and the inner rod.

[0007] As a further improvement of this utility model, a fluorescent ring is provided at the bottom of the outer rod, and a blocking ring is provided at the corresponding position of the inner rod to ensure that the blocking ring completely covers the fluorescent sticker ring in the initial state.

[0008] As a further improvement of this utility model, the inner rod is provided with a plurality of evenly distributed trigger blocks, and the inner side of the outer rod is provided with a plurality of trigger switches.

[0009] As a further improvement of this utility model, the tray base is provided with multiple LED beads, and each LED bead is connected to a corresponding trigger switch.

[0010] As a further improvement of this utility model, the host computer includes an audible and visual alarm device to provide timely reminders and ensure the normal use of the equipment.

[0011] The beneficial effects of this invention are as follows: By setting a displacement sensor between the inner and outer rods of the roof separation instrument and reading the observation data through a host computer connected to the displacement sensor, operators can directly obtain roof separation data at the bottom of the tunnel without climbing ladders or relying on telescopes. This achieves electronic display of the readings, avoiding the errors and inconveniences of manual reading and ensuring the accuracy of roof stability assessment. This invention also achieves dual light display through a fluorescent ring and LED beads. The fluorescent ring directly reflects whether separation has occurred, while the LED beads visually indicate the measurement range, facilitating observation during use and assisting the displacement sensor in reading the separation. This invention has a simple structure and is safe and reliable. Relying on the electronic display system composed of the host computer and LED beads, and the mechanical fluorescent indication composed of the fluorescent ring and scale, a dual protection mechanism of "active monitoring + passive backup" is formed. It can display and read specific displacement values ​​in real time, and can also visually reflect whether separation has occurred through the fluorescent ring. This completely solves the problems of cumbersome operation and environmental limitations in high-level roof observation, improving safety and reliability during use. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 As shown, an electronically displayed top plate delamination meter includes a tray base 1, with multiple anchor rods 9 on the top of the tray base 1, an outer rod 2 on the bottom of the tray base 1, an inner rod 3 inside the outer rod 2, a displacement sensor 7 between the outer rod 2 and the inner rod 3, and a host computer 8 connected to the displacement sensor 7. Both the outer rod 2 and the inner rod 3 are provided with scales.

[0016] The outer rod 2 has a fluorescent ring 4 at its bottom, and the inner rod 3 has a shielding ring 10 at the corresponding position to ensure that the shielding ring completely covers the fluorescent sticker ring in the initial state.

[0017] The inner rod 3 is provided with a plurality of evenly spaced trigger blocks 501, and the outer rod 2 is provided with a plurality of trigger switches 5 on its inner side.

[0018] The tray base 1 is equipped with multiple LED beads 6, and each LED bead 6 is connected to a corresponding trigger switch 5.

[0019] The host computer 8 includes an audible and visual alarm device.

[0020] When using this method, drilling can be performed using an anchor drill. The hole depth is generally 7-8m, and the hole diameter is 28-42mm. The drilling must be perpendicular to the top plate to ensure that the measuring rope hangs naturally. First, send the deep anchor head of anchor rod 9 to the designed position, tighten the measuring rope to confirm anchoring, then send the shallow anchor head of anchor rod 9 to the end position of anchor rod, and tighten the measuring rope again. Then connect the deep measuring rope to the inner rod 3 and the shallow measuring rope to the outer rod 2, and adjust the zero point to make the outer measuring cylinder reach the "0" scale. During measurement, the data is directly read through the host computer 8, and the lighting status of the LED beads 6 is used to confirm whether the host computer 8 is reading the data normally. When the host computer 8 is not running, the data can also be read through the scale on the outer rod 2 and the inner rod 3. The fluorescent ring 4 and the LED beads 6 can assist in reading data in dim environments.

[0021] The LED beads 6 are arranged with green, yellow and red beads in sequence. When the displacement of the inner rod 3 is ≤60mm, the green LED light is on and the host computer 8 displays the corresponding data. When the displacement of the inner rod 3 is between 60-120mm, the yellow and green lights are on at the same time and the host computer 8 displays the corresponding data at the same time. When the displacement of the inner rod 3 is ≥120mm, the top of the trigger switch 5 is contacted, the red, yellow and green lights are on at the same time, the host computer 8 displays the corresponding data and alarms.
