Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel monitoring, and in particular relates to a monitoring device for whether a tunnel is deformed. Background Technology

[0002] Tunnel deformation refers to the changes in shape and size of the surrounding rock during underground mining due to stress. Underground mining causes a redistribution of stress in the surrounding rock mass, leading to the stress on the tunnel's surrounding rock exceeding its ultimate strength, thus causing deformation. To determine the deformation of the tunnel during operation, monitoring devices are needed. However, these devices still have the following drawbacks in practical use:

[0003] When monitoring the deformation of a roadway, the device is installed in the roadway and different points are arranged. When it is necessary to continuously and accurately determine the deformation of a section of roadway, the operation requires a lot of sensors, which makes the monitoring inconvenient.

[0004] In monitoring the deformation of tunnel walls, the monitoring structure needs to be set up parallel to the tunnel wall. However, the alignment process requires the cooperation of multiple operators, making the setup of the device inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a monitoring device for whether a roadway is deformed. By setting up a support platform, support plate, sliding rod, I-shaped slider and support column, it solves the problems that it is not convenient to monitor the deformation of continuous roadways, and that setting up the monitoring device requires the cooperation of multiple people and is inconvenient to operate.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a monitoring device for whether a roadway is deformed, including a support platform, a support plate, a sliding rod, an I-shaped slider, and a support column. Support platforms are symmetrically arranged below the sliding rod, and are positioned below the two short sides of the bottom of the sliding rod. A support plate is arranged above each support platform. Support screws are vertically threaded in a circular array within each support plate. Screws are threaded around the top and bottom of the support screws on each support plate, and the screws on the top and bottom of the support screws abut against the support plate. A support bar is fixed at the center of the top of each support plate. The tops of two support bars are movably connected to a sliding rod. An I-shaped slider is movably connected within the sliding rod. Support column one and support column two are fixed at the edges of the tops of the two support plates, respectively. During operation, the support plate is supported by the support platform and the sliding rod is connected to it via the support screws. A laser pointer is connected to support column one, and a connecting column is connected to support column two.

[0008] Furthermore, a measuring ruler is movably connected through the lower part of the support platform and the I-shaped slider, and connecting rods are fixed at both ends of the measuring ruler. The distance between the support platform and the I-shaped slider and the tunnel is determined by the measuring ruler, and the measuring ruler abuts against the tunnel wall through the connecting rods.

[0009] Furthermore, each of the support platforms has an opening at the top center, and the bottom of the opening has a support port arranged in a ring array. The lower part of the periphery of each support screw is smooth, and the bottom end of the support screw is placed in the support port to support the support plate.

[0010] Furthermore, the bottom of the sliding rod has an insertion port corresponding to the two support bars, and the two support bars are respectively inserted into the insertion port, so that the support bars can restrict and support the sliding rod.

[0011] Furthermore, a movable opening is horizontally provided in the center of one side of the sliding rod, and the I-shaped slider is movably connected in the movable opening. The movable opening on the sliding rod is movably connected to the I-shaped slider.

[0012] Furthermore, a laser pointer is fixed to the top of the first support column, and a connecting column is fixed to the top of the second support column. A reflective patch is fixed to the end of the connecting column near the laser pointer. The light-emitting end of the laser pointer is positioned facing the reflective patch. The first support column supports the laser pointer on a support plate, and the second support column supports the connecting column on another connecting plate. When the laser pointer emits light just enough to illuminate the reflective patch, the two support plates are positioned at the same height on the tunnel floor.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient monitoring of deformation in continuous tunnels by setting up a sliding rod and an I-shaped slider. After setting up the support platform, support plate, and sliding rod, the measuring scale inside the I-shaped slider is slid until the connecting rod at one end of the measuring scale contacts the tunnel wall. After reading the scale at different positions on the tunnel wall, the above process is repeated in subsequent work to monitor and record the deformation of the tunnel, making it convenient to monitor deformation in continuous tunnels.

[0015] This invention solves the problem of inconvenient operation requiring multiple personnel to install a roadway deformation monitoring device by setting up a support platform, support plate, sliding rod, support column one, and support column two. Two support platforms are installed on the roadway floor, and the support plate is placed on top of the support platforms. The ends of the three support screws below the two support plates are inserted into the support openings on the support platforms. The two support platforms are then moved so that the distance between the two support bars equals the distance between the two insertion points. The connecting rods at one end of the measuring scale on the two support platforms are aligned with the roadway wall. The support platforms are then pushed so that one connecting rod on the measuring scale contacts the roadway wall. The measuring scale on the two support platforms is then adjusted to... After the readings are the same, support columns one and two on the two support plates support the laser pointer and the connecting column at the same height on the support plates, with the laser pointer's emitting end facing the connecting column and the reflective patch on the connecting column facing the laser pointer. Then, turn on the laser pointer, loosen all the screws at the top of the support plate, and then rotate the screws at the bottom of the support plate until the laser pointer shines on the reflective patch on the connecting column, so that the two support bars are set at the same height in the tunnel. Then, align the socket at the bottom of the sliding rod with the two support bars. After the support bars enter the socket, support column one is supported on the sliding rod. The whole operation can be performed by one person and is relatively convenient. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0027] Please see Figure 1-5This utility model is a monitoring device for whether a roadway is deformed. It includes a support platform 1, a support plate 2, a sliding rod 3, an I-shaped slider 4, and a support column 5. The support platforms 1 are symmetrically arranged below the sliding rod 3, and the sliding rod 3 movably connects the I-shaped slider 4 within it. The support platforms 1 provide support for the support plate 2 on the workbench surface, and are located below the two short sides of the bottom of the sliding rod 3. A support plate 2 is arranged above each support platform 1, supporting the sliding rod 3 on it. Support screws 202 are vertically threaded in a circular array inside the support plate 2. Screw cylinders 203 are threaded around the top and bottom of the support screws 202. The screw cylinder 203 on the rod 202 abuts against the support plate 2. During the rotation of the screw cylinder 203, the height of the support plate 2 on the support platform 1 is adjusted. A support bar 201 is fixed at the center of the top of each support plate 2. The support bar 201 movably connects the sliding rod 3 to it. The tops of the two support bars 201 are movably connected to the sliding rod 3. The sliding rod 3 movably connects the I-shaped slider 4 in it. The I-shaped slider 4 is movably connected inside the sliding rod 3. The I-shaped slider 4 movably connects the measuring ruler 103 in it. Support column 1 5 and support column 2 6 are fixed at the edges of the tops of the two support plates 2 that are far apart from each other. Support column 1 5 fixes the laser pointer 501 at its top. Support column 2 6 fixes the connecting column 601 at its top.

[0028] Specifically, a measuring scale 103 is movably connected through the lower part of the support platform 1 and the I-shaped slider 4, and connecting rods 104 are fixed at both ends of the measuring scale 103. When the measuring scale 103 is working, it extends a certain scale from the support platform 1 or the I-shaped slider 4 to determine the distance between the support platform 1 or the I-shaped slider 4 and the inner wall of the roadway being measured.

[0029] Furthermore, each support platform 1 has an opening 101 at the top center, and support ports 102 are arranged in a ring array at the bottom of the opening 101. The lower part of the periphery of each support screw 202 is smooth, and the bottom end of the support screw 202 is set in the support port 102. When the support platform 1 is working, the opening 101 provides a setting for inserting the support screw 202. When the support screw 202 is movably connected in the support port 102, it supports the support plate 2 on the support platform 1.

[0030] Furthermore, the bottom of the sliding rod 3 is provided with an insertion port 302 corresponding to the two support bars 201. The two support bars 201 are respectively inserted into the insertion port 302, and the insertion port 302 on the sliding rod 3 movably connects the I-shaped slider 4 therein.

[0031] Furthermore, a movable opening 301 is horizontally opened through the center of one side of the sliding rod 3, and the I-shaped slider 4 is movably connected in the movable opening 301, so that when the I-shaped slider 4 is slid, the distance between the I-shaped slider 4 and the tunnel wall can be measured by the measuring ruler 103.

[0032] The operation process of this embodiment is as follows: During operation, after setting up the support platform 1, support plate 2 and sliding rod 3, the measuring scale 103 inside the sliding I-shaped slider 4 is moved until the connecting rod 104 at one end of the measuring scale 103 contacts the wall of the tunnel. After reading the scale at different positions on the tunnel wall, the above work is repeated in subsequent work to monitor and record the deformation of the tunnel. Specific Implementation Example 2

[0033] Please see Figure 1-7 Based on the first specific embodiment, a laser pointer 501 is fixed to the top of the support column 5, and a connecting column 601 is fixed to the top of the support column 6. A reflective patch 602 is fixed to the end of the connecting column 601 near the laser pointer 501. The light-emitting end of the laser pointer 501 is set towards the reflective patch 602. The support column 5 fixes the laser pointer 501 on it. After the laser pointer 501 and the reflective patch 602 are at the same height, the laser emitted by the laser pointer 501 just illuminates the reflective patch 602 on the connecting column 601, thus ensuring that the sliding rod 3 and the tunnel are parallel to each other.

[0034] The operation process of this embodiment is as follows: During operation, firstly, two support platforms 1 are set on the ground in the tunnel, and support plates 2 are placed on top of the support platforms 1. The ends of the three support screws 202 below the two support plates 2 are inserted into the support openings 102 in the openings 101 on the support platforms 1. Then, the two support platforms 1 are moved so that the distance between the two support bars 201 is equal to the distance between the two insertion ports 302. The connecting rods 104 at one end of the measuring scales 103 on the two support platforms 1 are oriented towards the tunnel wall. Then, the support platforms 1 are pushed so that one connecting rod 104 on the measuring scales 103 contacts the tunnel wall. After adjusting the readings displayed on the measuring scales 103 on the two support platforms 1, the support columns 1 and 2 on the two support plates 2 are... 6. Support the laser pointer 501 and the connecting post 601 at the same height on the support plate 2, with the light-emitting end of the laser pointer 501 facing the connecting post 601 and the reflective patch 602 on the connecting post 601 facing the laser pointer 501. Then turn on the laser pointer 501, loosen all the screws 203 at the top of the support plate 2, and then rotate the screws 203 at the bottom of the support plate 2 until the laser pointer 501 shines on the reflective patch 602 on the connecting post 601, so that the two support bars 201 are set at the same height in the tunnel. Then align the insertion port 302 at the bottom of the sliding rod 3 with the two support bars 201. After the support bars 201 enter the insertion port 302, support the support post 5 on the sliding rod 3, and you can start working.
