Description

Technical Field

[0001] This utility model relates to the field of electromagnetic exploration technology, specifically a device for arranging electromagnetic exploration lines in underground tunnels. Background Technology

[0002] Accurate understanding of the distribution information of targets in underground tunnels provides technical support for the rational and safe planning and utilization of underground space, monitoring and early warning of geological disasters, strengthening the detection and protection capabilities of underground engineering projects, and eliminating safety hazards. Multiphysics modeling and response patterns of underground tunnels are the foundation for multiphysics data processing and interpretation, providing theoretical basis and scientific evaluation methods for underground space identification, positioning, and contour delineation. Through multiphysics modeling and characteristic analysis (gravity, magnetic, ground-penetrating radar, etc.), corresponding technical indicator requirements can be proposed for the development of intelligent sensing equipment, as well as data acquisition schemes for underground space detection / inspection / probing. It can also verify the reliability and accuracy of subsequent data processing, inversion, and underground space reconstruction.

[0003] Electromagnetic exploration is a geophysical exploration method widely used in underground resource exploration (such as minerals, oil and gas), environmental surveys, and engineering geological investigations. It infers the underground structure and composition by measuring the response of the underground medium to electromagnetic waves. Electromagnetic exploration primarily utilizes changes in electromagnetic waves or electric and magnetic fields to detect the properties of underground materials. Electromagnetic exploration requires electromagnetic transmitters and receivers to detect the electromagnetic response of the underground medium. These transmitters and receivers need to be connected by cables after being installed in underground tunnels, and the installation of these cables requires a wiring device. Therefore, an underground tunnel electromagnetic exploration wiring installation device is needed.

[0004] Existing electromagnetic survey line layout devices for underground tunnels support cables using cable racks and move the racks to arrange the cables at different locations inside the tunnel. However, most existing cable racks are inconvenient to accommodate multiple types of cables and do not support them, making the devices less practical. Therefore, this paper proposes an electromagnetic survey line layout device for underground tunnels to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that most existing cable racks are inconvenient to accommodate multiple types of cables and cannot support multiple types of cables, thus making the device less practical, this utility model proposes an electromagnetic exploration line layout device for underground tunnels.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the underground tunnel electromagnetic exploration line layout device of this utility model includes a base plate, and universal brake wheels are fixedly installed at the four corners of the bottom of the base plate.

[0007] Support plates are fixedly connected to the front and rear of the top of the base plate. An installation rod is installed between the two support plates through a disassembly assembly. A second arrangement wheel is rotatably connected to the center of the outer surface of the installation rod through a bearing. A first arrangement wheel is rotatably connected to the front and rear of the outer surface of the installation rod through a bearing. A limit assembly is provided below the two support plates.

[0008] Preferably, the limiting assembly includes an electric push rod one and an electric push rod two fixedly installed below one side of the support plate. The electric push rod one is located above the electric push rod two. The output ends of both the electric push rod one and the electric push rod two extend to the outside of the support plate. A through-hole limiting hole one is opened inside the lower part of the first arrangement wheel, and a through-hole limiting hole two is opened inside the lower part of the second arrangement wheel. The electric push rod one is adapted to the limiting hole one, and the electric push rod two is adapted to the limiting hole two.

[0009] Preferably, the disassembly assembly includes a through threaded hole formed inside the upper part of the support plate, a threaded rod threadedly connected inside the threaded hole, and an installation groove formed on the opposite side of each of the two threaded rods. An installation block is inserted into the installation groove, and the left and right sides of the installation rod are fixedly connected to the opposite side of the two installation blocks, respectively.

[0010] Preferably, two support blocks are fixedly connected to the lower side of one side of the support plate, and the two support blocks are respectively fixedly connected to electric push rod one and electric push rod two.

[0011] Preferably, the vertical cross-section of both the mounting groove and the mounting block is circular.

[0012] Preferably, a throttle is fixedly connected to one side of the outer surface of the threaded rod.

[0013] Preferably, handrails are fixedly connected to both the left and right sides of the top of the base plate.

[0014] The advantages of this utility model are:

[0015] 1. This utility model can install various types of cable test lines through the arrangement wheel one and arrangement wheel two on the mounting rod. When arranging the cable test lines, the arrangement wheel one or arrangement wheel two can be rotated to allow the cable test lines to be arranged and used, making it convenient to use. Thus, the device can support various types of cables and facilitates the arrangement of various types of cable test lines, making it highly practical.

[0016] 2. This utility model uses an installation block inserted into the installation groove to install the installation rod between two threaded rods. The threaded rods are threaded into the threaded holes of the support plate, supporting the installation rod and the installation block. When the installation rod is disassembled from the first and second arrangement wheels, rotating the threaded rod allows it to rotate out of the outer surface of the installation block, thus releasing it from the limiting pressure on the installation block and the installation rod. Furthermore, rotating the threaded rod holds the first and second arrangement wheels in place, and when the threaded rod moves out of the outer surface of the installation block, the installation rod can be disassembled from the first and second arrangement wheels. This facilitates modular disassembly and installation of the device, as well as its disassembly, transportation, and assembly during use. Attached Figure Description

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4 As shown, an electromagnetic exploration line layout device for underground tunnels includes a base plate 1, and universal brake wheels 4 are fixedly installed at the four corners of the bottom of the base plate 1.

[0027] Support plates 2 are fixedly connected to the front and rear of the top of the base plate 1. An installation rod 8 is installed between the two support plates 2 via a disassembly assembly 7. A second arrangement wheel 6 is rotatably connected to the center of the outer surface of the installation rod 8 via a bearing 1. Arrangement wheels 5 are rotatably connected to the front and rear of the outer surface of the installation rod 8 via bearing 2. A limit assembly 3 is provided below the two support plates 2. During operation, the device is easily moved by a universal brake wheel 4. When moving to a designated position for cable testing, the brake pads of the universal brake wheel 4 stop and stabilize the base plate 1. Various types of cables can then be installed using the arrangement wheels 5 and 6 on the installation rod 8. This device is designed for cable testing. When arranging the cable test lines, either the first arrangement wheel 5 or the second arrangement wheel 6 can be rotated to allow the cable test lines to be arranged, making it convenient to use. This allows the device to support various types of cables and facilitates the arrangement of various types of cable test lines, making it highly practical. Furthermore, the disassembly assembly 7 facilitates the disassembly and installation of the mounting rod 8, the first arrangement wheel 5, and the second arrangement wheel 6, making the disassembly, transportation, and assembly during use easy. The limiting assembly 3 can limit the unused arrangement wheels 5 and 6, preventing them from affecting the others when used individually. Therefore, this device is convenient to use and highly practical.

[0028] The limiting assembly 3 includes an electric push rod 31 and an electric push rod 32 fixedly installed on one side of the support plate 2. The electric push rod 31 is located above the electric push rod 32. The output ends of both the electric push rod 31 and the electric push rod 32 extend to the outside of the support plate 2. A through-hole limiting hole 33 is provided inside the lower part of the arrangement wheel 5, and a through-hole limiting hole 34 is provided inside the lower part of the arrangement wheel 6. The electric push rod 31 is adapted to the limiting hole 33, and the electric push rod 32 is adapted to the limiting hole 34. The device is adapted to the second hole 34. During operation, the output end of the electric push rod 31 is inserted into the first limiting hole 33 to limit the rotation of the first arrangement wheel 5. Similarly, the output end of the electric push rod 32 is inserted into the second limiting hole 34 to limit the rotation of the second arrangement wheel 6. Therefore, when one of the two arrangement wheels 5 and 6 rotates to arrange the cable, the others can be limited by the limiting post, thus avoiding affecting the arrangement of the cable measurement line. This allows the device to meet more usage requirements and has strong practicality.

[0029] The disassembly assembly 7 includes a through threaded hole 73 located inside the support plate 2. A threaded rod 71 is threadedly connected inside the threaded hole 73. Each of the two threaded rods 71 ​​has a mounting groove 74 on one side facing each other. A mounting block 75 is inserted into each mounting groove 74. The left and right sides of the mounting rod 8 are fixedly connected to the opposite sides of the two mounting blocks 75, respectively. During operation, the mounting blocks 75 are inserted into the mounting grooves 74, allowing the mounting rod 8 to be installed between the two threaded rods 71. The threaded rods 71 ​​are threaded into the threaded hole 73 of the support plate 2, thus ensuring the threaded rod 71... 1. The mounting rod 8 and the mounting block 75 are supported. When the mounting rod 8 is disassembled from the first arrangement wheel 5 and the second arrangement wheel 6, the threaded rod 71 is rotated so that the threaded rod 71 can rotate and move out from the outer surface of the mounting block 75, thereby disengaging from the limiting button on the mounting block 75 and the mounting rod 8. When the threaded rod 71 is rotated, the first arrangement wheel 5 and the second arrangement wheel 6 are held. When the threaded rod 71 moves out from the outer surface of the mounting block 75, the mounting rod 8 can be disassembled from the first arrangement wheel 5 and the second arrangement wheel 6. This facilitates the modular disassembly and installation of the device, and also facilitates the disassembly, transportation and assembly of the device during use.

[0030] Two support blocks 35 are fixedly connected to the lower side of one side of the support plate 2. The two support blocks 35 are fixedly connected to the electric push rod 31 and the electric push rod 32 respectively. During operation, the two support blocks 35 support the electric push rod 31 and the electric push rod 32 respectively, so that the electric push rod 31, the electric push rod 32 and the support plate 2 are installed stably.

[0031] The vertical cross-sections of the mounting groove 74 and the mounting block 75 are both circular. During operation, the circular mounting block 75 is inserted into the mounting groove 74, allowing the threaded rod 71 to rotate on the outer surface of the mounting block 75 when it is disassembled, and facilitating the disassembly of the mounting block 75 and the mounting rod 8.

[0032] A handle 72 is fixedly connected to one side of the outer surface of the threaded rod 71; during operation, the handle 72 facilitates the rotation of the threaded rod 71.

[0033] Example 2

[0034] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the top left and right sides of the base plate 1 are fixedly connected with handrails 9; during operation, the handrails 9 facilitate the connection of external ropes and other tools to the device, thereby driving the device to move inside the underground tunnel to arrange survey lines.
