Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a deformation detection device for mine roadways. Background Technology

[0002] In the mining process, it is necessary to excavate tunnels inside the mine to carry out the mining of metal ore. In order to ensure the stability of the mine tunnels, it is necessary to support and reinforce them.

[0003] Most of the reinforcement structures in mine roadways are traditional frame structures, which can support the top and sidewalls of the roadway. When the load-bearing pressure of the frame structure exceeds the threshold, the frame structure will collapse. Therefore, it is necessary to install detection devices inside the frame structure to detect the internal pressure and deformation of the frame structure. Traditional detection structures are mostly pressure sensors or displacement monitoring elements. Mine roadways are long, and multiple detection elements need to be arranged along the length of the roadway to ensure the detection length. Traditional detection structures need to be arranged at multiple points, which limits the detection area and the arrangement process is relatively cumbersome. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a mine roadway deformation detection device, which greatly increases the detection range, reduces the number of first detection components, and improves the efficiency of installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deformation detection device for mine roadways includes a support base. A first detection component is provided on the upper end of the support base. The first detection component includes a detection base and a telescopic end. An installation rod is fixed to the upper side wall of the telescopic end. Detection rods are respectively provided on both sides of the installation rod. The middle part of the detection rod is connected to the installation rod. The two detection rods are arranged at intervals and in opposite directions of inclination. A connecting component is provided on the side of the detection rod near the support base. The connecting component is connected to the support base in a relatively locked state.

[0007] Preferably, the support base has a through mounting groove on its surface, and the connecting assembly includes a first connecting rod connected to the side wall of the detection rod. The side wall of the first connecting rod is provided with a second connecting rod extending into the inside of the mounting groove. The lower end of the second connecting rod is provided with a horizontally arranged third connecting rod, which is located at the lower end of the mounting groove, and the first connecting rod is located at the upper end of the mounting groove.

[0008] Preferably, the length of the third connecting rod is greater than the width of the mounting groove, and the width of the third connecting rod is less than the width of the mounting groove.

[0009] Preferably, the second connecting rod and the third connecting rod are rotatably connected, and a torsion spring is provided at the rotatable connection point between them.

[0010] Preferably, the side wall of the detection rod has a plurality of mounting holes, the size of which is adapted to the size of the mounting rod.

[0011] Preferably, the first detection component is a first telescopic rod with a built-in pressure detection element, and a second telescopic rod is installed at the lower end of the first telescopic rod, the second telescopic rod being connected to the first telescopic rod.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] Through the above structural design, the combination of two detection rods and the first detection component can detect the deformation along the length of the support base, which greatly improves the detection range, reduces the number of first detection components, and improves the efficiency of installation. At the same time, the two detection rods are arranged at an angle in different directions, which can act as levers, improve the deformation detection effect, and avoid the accidental failure to detect deformation that occurs when the horizontal fixed arrangement is used.

Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] To address the technical problems mentioned in the background section, see Appendix Figure 1 - Appendix Figure 5 A deformation detection device for mine roadways includes a support base 100, and a first detection component 200 is provided on the upper end of the support base 100. The first detection component 200 can detect the deformation at the upper end, so as to judge the support status of the support structure in time and avoid collapse and safety accidents.

[0023] The first detection component 200 includes a detection base and a telescopic end 210. An installation rod 211 is fixed to the upper side wall of the telescopic end 210. Detection rods 300 are respectively provided on both sides of the installation rod 211. The middle part of the detection rod 300 is connected to the installation rod 211. The detection rod 300 extends along the length of the support base 100 and can detect the pressure at various positions along the length of the support base 100. When the detection rod 300 is compressed, it can drive the telescopic end 210 to descend through the installation rod 211, thereby realizing the detection of large-area deformation and collapse, increasing the detection area and reducing the number of pressure detection structures that need to be arranged.

[0024] Two detection rods 300 are arranged at intervals and tilted in opposite directions. A connecting component 400 is provided on the side of the detection rod 300 near the support base 100. The connecting component 400 is connected to the support base 100 in a relatively locked state. When pressure is applied to any position along the length of the support base 100, the detection rod 300 can be controlled to descend. Furthermore, the deformation located far from the first detection component 200 can be amplified by the lever structure formed by the detection rod 300, thus avoiding the phenomenon of detection failure due to the detection rod 300 being too long.

[0025] During the process of the detection rod 300 being compressed, under the limitation of the connecting component 400, the vertical direction of the first end of the detection rod 300 remains relatively unchanged, while it can be in a movable state along the length direction of the support base 100.

[0026] In summary, through the above structural design, the combination of two detection rods 300 and the first detection component 200 can detect the deformation along the length of the support base 100, which greatly improves the detection range, reduces the number of first detection components 200, and improves the efficiency of installation. At the same time, the two detection rods 300 are arranged at different inclines, which can act as levers, improve the deformation detection effect, and avoid the accidental failure to detect deformation that occurs when the horizontal fixed arrangement is used.

[0027] A mounting groove 110 extending vertically through the surface of the support base 100 is provided. The connecting assembly 400 includes a first connecting rod 430 connected to the side wall of the detection rod 300. A second connecting rod 420 extending into the inside of the mounting groove 110 is provided on the side wall of the first connecting rod 430. A third connecting rod 410 arranged horizontally is provided at the lower end of the second connecting rod 420. The third connecting rod 410 is located at the lower end of the mounting groove 110, and the first connecting rod 430 is located at the upper end of the mounting groove 110.

[0028] The third connecting rod 410 and the first connecting rod 430 are located on both sides of the support base 100. The third connecting rod 410 at the lower end can engage with the first connecting rod 430 at the upper end and the first detection component 200, and can engage and limit the detection rod 300 on the side close to the support base 100 to ensure overall stability.

[0029] The first connecting rod 430 is preferably rotatably connected to the detection rod 300. During the deflection of the detection rod 300, the position of the connecting component 400 will not be affected, thus ensuring the normal operation of the overall pressure detection.

[0030] Furthermore, the length of the third connecting rod 410 is greater than the width of the mounting groove 110, and the width of the third connecting rod 410 is less than the width of the mounting groove 110. By rotating the third connecting rod 410 to different positions, the engagement state of the third connecting rod 410 can be adjusted. In the installed state, the third connecting rod 410 can be rotated to be in the same length direction as the support base 100, so that the third connecting rod 410 passes through the mounting groove 110 and enters the lower end of the support base 100; then, the rotation of the third connecting rod 410 is controlled to cross the support base 100, thereby achieving engagement and limiting. Through the above structural design, the installation and limiting of the overall structure of the connecting component 400 are facilitated, ensuring the stability of the overall structure.

[0031] The second connecting rod 420 is rotatably connected to the third connecting rod 410, and a torsion spring is provided at the rotatable connection point. Through the above structural design, the third connecting rod 410 can be in a deflected state under normal conditions and cross the support base 100, thus preventing the third connecting rod 410 from separating from the support base 100 under normal conditions.

[0032] Several mounting holes are provided on the side wall of the detection rod 300. The size of the mounting holes is adapted to the size of the mounting rod 211. By aligning the different mounting holes of the detection rod 300 with the mounting rod 211, the detection range and tilt state of the detection rod 300 can be adjusted to meet different detection environments.

[0033] The first detection component 200 is a first telescopic rod with a built-in pressure detection element. A second telescopic rod 500 is installed at the lower end of the first telescopic rod and is connected to the first telescopic rod. The internal size of the first detection component 200 is smaller than the internal size of the second telescopic rod 500. During the compression of the second telescopic rod 500, the internal control medium can be pushed into the first detection component 200 or drawn into the first detection component 200 to control the first detection component 200 to contract or extend.

[0034] Because the internal dimensions of the first detection component 200 are smaller, its deformation is greater, and the detection effect is more accurate. The second telescopic rod 500 can quickly detect the presence or absence of deformation, and the first detection component 200 can accurately detect the amount of deformation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
