Description

Technical Field

[0001] This invention belongs to the field of subway cable laying technology, and in particular relates to a subway cable laying device. Background Technology

[0002] With the acceleration of urbanization, the subway network continues to extend to the suburbs and the line density is constantly increasing, which puts forward higher requirements for the laying quality and construction efficiency of power supply cables. As the core carrier of power transmission, subway cables need to be laid in complex spaces such as tunnels, platform mezzanines, and underground pipe corridors. They not only need to meet the transmission requirements of high voltage and high current, but also need to adapt to narrow working environments, curved laying paths, and special working conditions such as vibration resistance and corrosion resistance. In order to adapt to the narrow space layout, some cables need to be installed on the side wall of the tunnel. For example, a subway cable laying device is proposed in patent publication number CN218434194U.

[0003] During the operation of existing subway cable laying equipment, the cable needs to be laid on the pre-set supports on the tunnel sidewall. However, some supports are prone to residual burrs, flash, and sharp metal edges during the manufacturing process. When the laying equipment pulls the cable with tension and lays it on the support, the cable surface will continuously wear and rub against these sharp parts. Especially under tension, the sharp parts are prone to scratching or even cutting the cable insulation layer, directly weakening the insulation protection performance of the cable and creating safety hazards.

[0004] In addition, when traditional laying equipment pulls cables to high-altitude work sites, some cable sections are exposed to the external environment for a long time. During the movement of the laying equipment, these exposed cable sections are very likely to get caught and entangled with other supports or protruding structures on the tunnel wall, which not only interferes with the continuous laying operation, but also significantly reduces the overall construction efficiency and increases the operating cost and safety risks.

[0005] Therefore, a subway cable laying device is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a subway cable laying device.

Multiple second lead screw linear modules are fixedly connected to the upper side wall of the mounting plate. The moving ends of the multiple second lead screw linear modules are respectively fixedly connected to the lower side walls of the multiple adjustment frames.

[0013] In the aforementioned subway cable laying device, the inspection and cleaning assembly includes a support frame fixedly connected to the side wall of the protective guide cover. A second electric push rod is fixedly connected to the upper side wall of the support frame. The output end of the second electric push rod passes through the support frame and is fixedly connected to a small linear motor.

[0016] In the aforementioned subway cable laying device, two guide frames are symmetrically fixedly connected to the upper side wall of the horizontal conveyor seat, and the guide frames are arc-shaped structures.

[0017] In the aforementioned subway cable laying device, a gas collecting hood is connected to the side wall of the support frame, and a separation box is connected to the lower side wall of the gas collecting hood. The separation box is filled with a liquid separating agent, and the gas collecting hood and the separation box are connected by the same air inlet pipe located in the liquid separating agent. A vacuum pump is connected to the side wall of the separation box.

[0018] Compared with existing technologies, the advantages of subway cable laying equipment are:

[0019] 1. The pre-installed detection and cleaning components automatically pre-grind the sharp parts of the supports before the cable is laid on the inner wall of the subway tunnel using the cable laying device. This completely eliminates defects such as burrs, flash, and sharp metal edges left over from the support production process, smoothing the contact surface of the supports to a smooth and flat state. This avoids wear and scratches caused by tension traction and sharp parts of the supports during cable laying, effectively protecting the integrity of the cable insulation layer and preventing damage or tearing that could reduce protective performance. This reduces the risk of short circuits and leakage in the later stages, extends the cable's service life and maintenance cycle, optimizes the contact compatibility between the cable and the supports, reduces frictional resistance between the cable and the supports during laying, makes cable traction and erection smoother, reduces the load loss of the laying equipment, and improves the continuity of operations and construction efficiency.

[0020] 2. By using protective guide covers and conveying components, the cables are protected during the laying process using the laying device. This directly avoids mechanical damage caused by snagging, prevents the insulation layer from being pulled, torn, or the conductor from being damaged, and ensures the integrity of the cable structure and the stability of its electrical performance. This reduces safety hazards such as short circuits and leakage during later operation, and reduces maintenance costs and the risk of downtime. Secondly, it ensures the continuity of cable laying, avoiding work interruptions, equipment downtime, or cable rework caused by snagging, improving overall construction efficiency, shortening the construction period, and controlling project costs. Furthermore, it reduces the load impact of the additional pulling force generated by snagging on the cable and laying device, reduces equipment wear and secondary damage caused by excessive cable tension, and extends the service life of the laying equipment and the service life of the cable.

[0021] 3. Through the designed conveyor components, when the conveyor belt inside the laying device wears down after prolonged use, the worn belt can be quickly and accurately located and dealt with promptly. This prevents the worn belt from aggravating wear due to continuous use, and avoids sudden interruptions in laying operations caused by belt breakage, slippage, or conveyor failure, ensuring the continuity of cable laying and reducing project delays and increased construction costs due to downtime. Secondly, the rapid location of the worn belt improves the efficiency of operation and maintenance response, making repair and replacement operations more targeted, reducing unnecessary disassembly and inspection time, ensuring that the construction progresses according to plan, and ensuring the stability and smoothness of cable conveying in subsequent laying operations, maintaining the consistency of laying quality, and providing reliable support for the efficient and safe implementation of subway cable projects.

[0034] The path adjustment component 16 is disposed on the upper side wall of the mounting plate 1. The path adjustment component 16 includes multiple adjustment frames 161.

[0036] A fixing frame 29 is fixedly connected to the rear side wall of the protective guide cover 4. The fixing frame 29 has an inverted U-shaped structure. A guide cylinder 30 is fixedly connected to the front end of the fixing frame 29. Multiple limiting plates 31 are distributed in a ring on the outer wall of the guide cylinder 30. The limiting plates 31 have an inverted L-shaped structure. Multiple elastic telescopic rods 32 are fixedly connected to the inner wall of the limiting plates 31.

[0037] The side wall of the support frame 221 is connected to a gas collection hood 38, and the lower side wall of the gas collection hood 38 is connected to a separation box 39. The separation box 39 is filled with a liquid separating agent. The gas collection hood 38 and the separation box 39 are connected by the same air inlet pipe 40 located in the liquid separating agent. The side wall of the separation box 39 is connected to an air extractor 41, which can handle the dust generated during grinding.

[0038] The operating principle of the present invention is explained as follows: The cable unwinding frame mechanism 3 is installed on the surface of the mounting plate 1. Then, the operator manually guides the end of the cable through the top of the horizontal conveyor seat 5, the middle of multiple adjusting rollers 18, the guide roller 36, the protective guide cover 4, and the guide cylinder 30. Then, the operator uses tools such as clamps to fix one end of the cable to a bracket on one side of the subway tunnel wall (the first bracket is manually observed and the sharp parts are manually ground).

[0039] Next, the operator manually rotates multiple threaded rods 17. Through the threaded engagement between the threaded rods 17 and the threaded cylinder 162, the threaded rods 17 drive multiple adjusting rollers 18 to move closer to the cable. When the operator sees the adjusting rollers 18 contacting the cable, they can stop rotating the threaded rods 17 (the threaded rods 17 are self-locking, which can prevent the threaded rods 17 from reversing). Then, the operator sends an electrical signal to the controller 2 through an external control switch. After receiving the electrical signal, the controller 2 controls the first linear screw module 9 and multiple second linear screw modules 21 to work. The first linear screw module 9 drives the hydraulic cylinder 81 to move towards the set position closer to the tunnel wall support through the adjusting plate 82. At the same time, the multiple second linear screw modules 21... 1. The adjustment frame 161 drives multiple adjustment rollers 18 to move, and the adjustment rollers 18 are used to adjust the movement path of the cable. Then, the controller 2 controls multiple first electric push rods 7 to work. Two first electric push rods 7 located on the same side will drive the conveyor frame 111 to move towards the cable to a set position. The moving position is adjusted by the operator according to the diameter of the cable, so that the conveyor frame 111 drives the conveyor belt 12 to contact the cable insulation layer and maintain a certain pressure (the moving end of the first electric push rod 7 is connected to the conveyor frame 111 through a pressure sensor, which is not shown in the figure. After the controller 2 detects that the pressure between the conveyor belt 12 and the cable insulation layer is 200N through the pressure sensor, it will control the first electric push rod 7 to stop working).

[0040] Once the cable path is adjusted, the operator sends an electrical signal to controller 2 via an external control switch. Controller 2 then controls the drive wheel to operate, moving the device within the tunnel. During this movement, as the protective guide cover 4 approaches the support frame, it moves the vision sensor 26 above the support frame via the support frame 221. Therefore, during the device's movement, controller 2 uses the vision sensor 26 to detect the surface condition of the support frame. When controller 2 detects a sharp part on the surface of the support frame ahead via the vision sensor 26, controller 2 immediately stops the drive wheel, allowing the vision sensor 26 to remain on the support frame. Next, controller 2 controls drive motor 27 to work, drive motor 27 will drive rotating plate 25 to rotate 180 degrees, so that rotating plate 25 drives electric grinding roller 28 to rotate downward. Then, controller 2 controls electric grinding roller 28 to work, and controls second electric push rod 222 to work. Second electric push rod 222 will drive small linear motor 23 and electric grinding roller 28 to move downward together, so that electric grinding roller 28 contacts bracket. Then, controller 2 controls small linear motor 23 to work, using small linear motor 23 to drive electric grinding roller 28 to move back and forth above bracket, using electric grinding roller 28 to grind the sharp parts of bracket surface, avoiding scratching cables;

[0041] During the operation of the cable laying device, a dedicated operator needs to spend a certain amount of time fixing the cables on the support. When the operator sees continuous slight scratching on the cable insulation layer, it indicates that the conveyor belt 12 is worn. The operator then needs to send an electrical signal to the controller 2 through an external switch. After receiving the electrical signal, the controller 2 will control multiple small electric push rods 13 to work. The small electric push rods 13 will drive the resistance detection wheel 14 to move towards the conveyor belt 12 to a set position, so that the resistance detection wheel 14 contacts the conveyor belt 12. The friction between the conveyor belt 12 and the resistance detection wheel 14 will drive the resistance detection wheel 14 to rotate. When the conveyor belt 12 is worn, the friction between the conveyor belt 12 and the resistance detection wheel 14 will decrease, and the rotation speed of the resistance detection wheel 14 will also decrease. After the controller 2 detects this situation through the encoder 15, it will display this information on the external display screen, so that the operator can quickly find the worn conveyor belt 12 for replacement.

[0042] Example 2

[0043] like Figures 7-8 As shown, a gas collection hood 38 is connected to the side wall of the support frame 221, and a separation box 39 is connected to the lower side wall of the gas collection hood 38. The separation box 39 is filled with a liquid separating agent. The gas collection hood 38 and the separation box 39 are connected by the same air inlet pipe 40 located in the liquid separating agent. A vacuum pump 41 is connected to the side wall of the separation box 39.

[0044] While the electric grinding roller 28 is grinding the bracket, the controller 2 will also control the air extractor 41 to work. The air extractor 41 will extract the gas inside the separation box 39, thereby reducing the air pressure inside the separation box 39. The external gas will carry the dust off the grinding through the gas collection hood 38 and the air inlet pipe 40 into the liquid separator, and the liquid separator will be used to filter the dust generated during grinding.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
