Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying structure for electromechanical installation in coal mines. Background Technology

[0002] Electromechanical engineering includes coal mine electromechanical work and building electromechanical engineering. Coal mine electromechanical installation refers to a series of tasks in the coal mine production environment, including the installation and commissioning of various electromechanical equipment and related auxiliary facilities in accordance with design requirements and safety specifications. When installing coal mine electromechanical equipment, cables need to be laid.

[0003] When laying cables, the cables need to be passed through conduits. When installing cables in conduits, care should be taken to ensure that the cables are not kinked and to minimize the number of splices. Since the cables are run through conduits, it is not convenient to observe the cable threading condition inside the conduit when the cables need to be inspected. The conduit also needs to be disassembled, which is troublesome and may cause damage to the conduit.

[0004] The existing patent (publication number: CN220673284U) discloses a cable laying structure for electromechanical engineering. This utility model connects two clamp tubes to form a conduit, which facilitates the installation and disassembly of the conduit and also facilitates the inspection and maintenance of the cables inside the conduit.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, these patents do not allow for convenient positioning of the cable after it has been moved into the card slot. Due to the cable's elasticity, it is highly likely that the cable will bend or twist due to its elasticity when the cover plate is placed on top of the card slot, causing it to deviate from the card slot and affecting the cover plate's position on top of the card slot, thus impacting the cable laying and installation efficiency.

[0006] Therefore, a cable laying structure for electromechanical installation in coal mines is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a cable laying structure for coal mine electromechanical installation, which can solve the problem in existing patents that it is inconvenient to limit the cable after it is moved into the card holder. Due to the elasticity of the cable, when the cover plate is placed on top of the card holder in the future, the cable is very likely to bend or twist due to the elasticity, thereby shifting out of the card holder and affecting the cover plate's position on top of the card holder, thus affecting the efficiency of cable laying and installation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cable laying structure for coal mine electromechanical installation, including a laying frame, a pressing mechanism inside the laying frame, a fixing plate fixedly connected to the left side of the laying frame, a wire threading mechanism on the top of the fixing plate, a limit screw on the top of the laying frame, and an internal hexagonal swivel block on the top of the fixing plate.

[0009] The threading mechanism includes an elastic rubber roller, two first rotating frames, three rotating rollers, and three second rotating frames. The elastic rubber roller is rotatably connected between opposite sides of the two first rotating frames. The bottom of the first rotating frame is fixedly connected to the top of the fixed plate. The rotating roller is rotatably connected between opposite sides of adjacent second rotating frames. The bottom of the second rotating frame is fixedly connected to the top of the fixed plate.

[0010] Preferably, the rear side of the internal hexagonal swivel block passes through the front first rotating frame and is fixedly connected to the front side of the elastic rubber roller, and the surface of the internal hexagonal swivel block is rotatably connected to the interior of the front first rotating frame.

[0011] Preferably, the bottom of the inner wall of the laying frame is provided with a wire groove, and the number of wire grooves is three, with the rotating roller located on the left side of the wire groove.

[0012] Preferably, two silicone baffles are fixedly connected to the bottom of the inner wall of the laying frame.

[0013] Preferably, the pressing mechanism includes a pressure plate, three pressure strips and three anti-slip strips. The surface of the pressure plate is in movable contact with the inner wall of the laying frame. The top of the pressure strip is fixedly connected to the bottom of the pressure plate. The top of the anti-slip strip is fixedly connected to the bottom of the pressure strip. The anti-slip strip is located at the top of the wire groove.

[0014] Preferably, each of the four corners of the top of the pressure plate is fixedly connected with a tension spring, and the top of the tension spring is fixedly connected to the top of the inner wall of the laying frame.

[0015] Preferably, the bottom of the limiting screw passes through the laying frame and is in close contact with the top of the pressure plate, and the surface of the limiting screw is threadedly connected to the inner wall of the laying frame.

[0016] Preferably, mounting blocks are fixedly connected to the bottom of both the front and rear sides of the laying frame, and the number of mounting blocks is several and they are evenly distributed on the surface of the laying frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up an elastic rubber roller and a rotating roller, allows the cable after the coal mine electromechanical equipment is installed to be moved between the elastic rubber roller and the rotating roller. The elasticity of the elastic rubber roller clamps the cable. Then, an electric handle is connected to an internal hexagonal rotating block and rotated. At this time, the internal hexagonal rotating block can drive the elastic rubber roller to rotate, which can quickly thread the cable into the cable tray. Through the cylindrical space formed between the pressure plate, silicone baffle and laying frame, the position of the cable can be prevented from shifting during the threading process, thus quickly completing the cable threading process.

[0019] 2. This application uses a limit screw. After the limit screw is tightened, it will push the pressure plate downward, causing the tension spring to stretch. At this time, the pressure strip and anti-slip strip will move downward, so that the anti-slip strip can stably clamp the cable, keeping the cable stable inside the laying frame. Then, the laying frame can be easily fixed by passing an external bolt through the mounting block, thus quickly completing the cable laying work. The laying frame can protect the cable. Since the silicone strip is elastic and soft, it can avoid blocking the downward movement of the pressure plate. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A cable laying structure for electromechanical installation in a coal mine includes a laying frame 1, a pressing mechanism 5 inside the laying frame 1, a fixing plate 3 fixedly connected to the left side of the laying frame 1, a wire threading mechanism 4 on the top of the fixing plate 3, a limit screw 6 on the top of the laying frame 1, and an internal hexagonal swivel block 9 on the top of the fixing plate 3.

[0029] The threading mechanism 4 includes an elastic rubber roller 401, two first rotating frames 402, three rotating rollers 403, and three second rotating frames 404. The elastic rubber roller 401 is rotatably connected between the two first rotating frames 402 on opposite sides. The bottom of the first rotating frame 402 is fixedly connected to the top of the fixed plate 3. The rotating rollers 403 are rotatably connected between the adjacent second rotating frames 404 on opposite sides. The bottom of the second rotating frame 404 is fixedly connected to the top of the fixed plate 3.

[0030] In this embodiment: When laying cables for coal mine electromechanical equipment, the cable is placed between the elastic rubber roller 401 and the rotating roller 403. The elastic rubber roller 401 clamps the cable. By rotating the internal hexagonal block 9 with an external wrench, the elastic rubber roller 401 is rotated. With the rotational support of the rotating roller 403, the cable can be quickly threaded into the cable tray 8. During the threading process, the cylindrical space formed by the pressure plate 501, the silicone baffle 7, and the laying frame 1 prevents the cable from shifting position. After the threading is completed, the limit screw 6 is rotated to press down the pressure plate 501, the tension spring 10 extends, and the pressure strip... The cable is tightly clamped by 502 and anti-slip strip 503 and fixed inside the laying frame 1. The laying frame 1 can protect the cable. Then, the laying frame 1 is fixed by passing the external bolt through the mounting block 2 to complete the laying. This effectively improves the cable pulling efficiency and avoids the problem in the existing patent that it is inconvenient to limit the cable after it is moved into the card seat. Because the cable has a certain degree of elasticity, the cable is very likely to bend or twist due to elasticity when the cover plate is placed on top of the card seat in the future, thereby shifting out of the card seat and affecting the cover plate's position on top of the card seat, thus affecting the cable laying and installation efficiency.

[0031] Specifically, such as Figure 3As shown, the rear side of the internal hexagonal swivel block 9 passes through the front first rotating frame 402 and is fixedly connected to the front side of the elastic rubber roller 401. The surface of the internal hexagonal swivel block 9 is rotatably connected to the interior of the front first rotating frame 402.

[0032] Specifically, such as Figure 2 As shown, the bottom of the inner wall of the laying frame 1 is provided with a wire groove 8, and there are three wire grooves 8. The rotating roller 403 is located on the left side of the wire groove 8.

[0033] Specifically, such as Figure 2 As shown, two silicone baffles 7 are fixedly connected to the bottom of the inner wall of the laying frame 1.

[0034] In this embodiment: the rear side of the internal hexagonal block 9 passes through the front first rotating frame 402 and is fixedly connected to the elastic rubber roller 401. When the external wrench is connected to the internal hexagonal block 9 and rotated, the elastic rubber roller 401 can also rotate. By opening a wire groove 8 at the bottom of the inner wall of the laying frame 1, the cable can be easily accommodated. The cylindrical space formed between the pressure plate 501, the silicone baffle 7 and the laying frame 1 can prevent the cable from shifting during the threading process. In addition, the silicone baffle 7 is elastic and soft, so it can avoid blocking the pressure plate 501 from moving downward.

[0035] Specifically, such as Figure 4 As shown, the pressing mechanism 5 includes a pressing plate 501, three pressing strips 502 and three anti-slip strips 503. The surface of the pressing plate 501 is in movable contact with the inner wall of the laying frame 1. The top of the pressing strip 502 is fixedly connected to the bottom of the pressing plate 501. The top of the anti-slip strip 503 is fixedly connected to the bottom of the pressing strip 502. The anti-slip strip 503 is located at the top of the wire groove 8.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, tension springs 10 are fixedly connected to the four corners of the top of the pressure plate 501, and the top of the tension springs 10 is fixedly connected to the top of the inner wall of the laying frame 1.

[0037] In this embodiment: by moving the pressure plate 501 downwards, the tension spring 10 can cause the pressure strip 502 and the anti-slip strip 503 to move downwards, so that the anti-slip strip 503 is in close contact with the cable inside the cable tray 8, thereby limiting the cable inside the laying frame 1 for protection. The upward pulling force of the tension spring 10 on the pressure plate 501 can prevent the pressure plate 501 from moving to the bottom of the laying frame 1 and affecting the normal cable threading work.

[0038] Specifically, such as Figure 1 and Figure 5 As shown, the bottom of the limiting screw 6 passes through the laying frame 1 and is in close contact with the top of the pressure plate 501, and the surface of the limiting screw 6 is threadedly connected to the inner wall of the laying frame 1.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, mounting blocks 2 are fixedly connected to the bottom of the front and rear sides of the laying frame 1. There are several mounting blocks 2, which are evenly distributed on the surface of the laying frame 1.

[0040] In this embodiment: the limiting screw 6 is connected to the thread inside the laying frame 1. When the limiting screw 6 is rotated, it can move downward, thereby pressing the pressure plate 501 downward. By loosening the limiting screw 6, the tension spring 10 can retract, pulling the pressure plate 501, pressure strip 502 and anti-slip strip 503 upward until the anti-slip strip 503 is out of contact with the cable. This allows the elastic rubber roller 401 to be rotated in the opposite direction to quickly pull out and replace the cable. By using an external bolt to pass through the mounting block 2, the laying frame 1 can be fixed, thus completing the cable laying work.

[0041] Working principle: By moving the coal mine electromechanical equipment cable to be laid between the elastic rubber roller 401 and the rotating roller 403, the elasticity of the elastic rubber roller 401 clamps the cable. Then, an external wrench is inserted into the internal hexagonal block 9, and the rotation of the external wrench causes the internal hexagonal block 9 to drive the elastic rubber roller 401 to rotate. The rotating roller 403 supports the rotation of the cable, and the rotating elastic rubber roller 401 and the rotating roller 403 feed the cable into the cable threading groove 8. The cable is quickly threaded into the groove 8. The cylindrical space formed between the pressure plate 501, the silicone baffle 7, and the laying frame 1 prevents the cable from shifting position during threading. After threading, the limiting screw 6 is rotated. The limiting screw 6 is threaded into the laying frame 1. When the limiting screw 6 rotates, it moves downward to press the pressure plate 501. At this time, the tension spring 10 extends, and the pressure strip 502 and... The anti-slip strip 503 can move downwards, tightly clamping the cable after threading, thus fixing the cable inside the laying frame 1 and protecting it. Then, by using an external bolt through the mounting block 2, the laying frame 1 can be fixed, completing the cable laying work. This effectively improves the threading efficiency and avoids the problem in existing patents where it is inconvenient to limit the cable after it has been moved into the card slot. Due to the elasticity of the cable, it is highly likely that the cable will bend or twist due to its elasticity when the cover plate is placed on top of the card slot, causing it to deviate from the card slot and affecting the cover plate's position on top of the card slot, thus affecting the cable laying and installation efficiency. By loosening the limiting screw 6, the tension spring 10 can rebound, pulling the pressure plate 501, pressure strip 502, and anti-slip strip 503 out of contact with the cable. Then, an external wrench can be inserted into the internal hexagonal swivel block 9 to rotate in the opposite direction, allowing the cable to be pulled out and replaced.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
