Description

Technical Field

[0001] This invention belongs to the technical field of cable protection equipment, specifically relating to a ground line protection device for urban rail transit signal construction. Background Technology

[0002] Urban rail transit includes: subway systems, light rail systems, monorail systems, trams, maglev systems, automated guided train systems, and urban rapid transit systems. In addition, with the development of transportation systems, other new transportation systems have emerged. Urban rail transit is the backbone of urban public transportation, characterized by energy saving, land saving, large capacity, all-weather operation, and low or no pollution (and safety), making it a green and environmentally friendly transportation system, particularly suitable for large and medium-sized cities. Ground-level cabling is required during the construction of urban rail transit systems.

[0003] A prior art patent, CN112310926B, describes a ground cable protection device. This patent includes a protection plate formed by connecting multiple sub-protective plates end-to-end with a rigid rope. Each sub-protective plate has slots along its length, and the end-to-end connection of the sub-protective plates creates a cable passage groove. Multiple fixing plates are also included, with the sub-protective plates correspondingly positioned on them, and each fixing plate having fixing holes. This solution indirectly fixes the protection plate, preventing it from shifting forward and breaking cables as construction vehicles pass by. Furthermore, the multi-section connection of the protection plate is suitable for use on flat surfaces. While the patented protective plate offers protection and can be used on uneven surfaces, thus expanding its applicability, it still has the following shortcomings in practical use: From a practical standpoint, the assembly method for multi-section protective plates is inconvenient, hindering rapid assembly and reducing installation efficiency. Furthermore, after assembling multiple sections, the connected protective plates cannot rotate, preventing angle adjustment based on ground slopes and reducing practicality. Additionally, it fails to effectively limit and protect wiring, making it difficult for wiring to move within the device and affecting its stability.

[0004] Therefore, there is a need for a ground line protection device for urban rail transit signal construction to solve the problems of inconvenience in assembly and use, inability to adjust the angle according to the ground slope after assembly, and inability to effectively limit the wiring for protection in the existing technology. Summary of the Invention

[0027] The present invention will be further described below with reference to embodiments.

[0028] Please see Figure 1-6This invention provides a ground line protection device for urban rail transit signal construction, including a base 1 and a protection module 2. The protection module 2 includes a protection block 201 and a connecting block 202. The connecting block 202 is fixedly connected to the front and rear sides of the bottom of the protection module 2. An installation mechanism 3 is provided below the protection block 201. The protection module 2 is detachably installed on the upper part of the base 1 through the installation mechanism 3. A limit rod 203 is fixedly connected to one side of the inner surface of the connecting block 202. The limit rod 203 is provided with a matching limit groove 204 at a corresponding position on the installation mechanism 3. The connecting block 202 is movably connected to the installation mechanism 3 through the limit rod 203 and the limit groove 204. A limit mechanism 8 is provided on the upper part of the base 1. A rotating connection mechanism 5 is provided on the bottom of the base 1 for assembling and connecting the base 1. An installation pad 7 is fixedly connected to the bottom of the base 1. A sliding mechanism 6 is provided on the protection block 201 for connecting and protecting the protection block 201. Installation holes 101 are provided on the front and rear sides of the base 1.

[0029] Further as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the protective block 201 is elastic and can provide support and cushioning under pressure, thereby protecting the entire device and improving its protective performance. The upper surface of the protective block 201 is coated with an anti-slip layer or has anti-slip grooves to improve its anti-slip performance.

[0030] In use, the limiting rod 203 allows the protective block 201 to be movably installed on the mounting frame 302. Specifically, the limiting rod 203 aligns with and slides within the limiting groove 204, allowing the protective block 201 to slide on the mounting frame 302. The protective block 201 provides support and protection, effectively reducing the pressure on the internal cables of the device. Furthermore, with the limiting rod 203 in place, the connecting block 202 is movably connected to the mounting frame 302 via the limiting rod 203 and the limiting groove 204. When the protective block 201 is subjected to pressure, the force is transmitted to the limiting rod 203 through the connecting block 202, causing the limiting rod 203 to slide within the limiting groove 204. This disperses and releases the force on the protective block 201, thereby improving its service life and protective performance.

[0031] Further as Figure 1 , Figure 5 and Figure 6As shown, it is worth noting that the installation mechanism 3 includes an L-shaped installation block 301, which is fixedly connected to the top of the base 1. An installation frame 302 is slidably installed on the L-shaped installation block 301. The installation frame 302 is movably located at the bottom of the protective block 201 via a limiting rod 203 and a limiting groove 204. The limiting groove 204 is opened on the installation frame 302. A positioning block 303 is fixedly connected to the bottom of the installation frame 302. A stop block 304 is fixedly connected to the left side of the L-shaped installation block 301. A stop groove 305 is opened on the left side of the installation frame 302 corresponding to the stop block 304. The installation frame 302 is slidably limited on the installation frame 302 by the stop block 304. A wire groove 4 is opened at the bottom of the positioning block 303.

[0032] Further as Figure 1 , Figure 5 and Figure 6 As shown, it is worth noting that the positioning block 303 is made of an elastic material, which allows the positioning block 303 to deform in accordance with the rotation of the base 1, thereby improving the stability of its connection.

[0033] In use, when installing the protective block 201 on the base 1, the mounting frame 302 slides the protective block 201 onto the L-shaped mounting block 301 from the right side, allowing the protective block 201 to slide onto the upper part of the base 1. At this time, the positioning block 303 can limit the cable, and with the setting of the stop block 304 and the setting of the sliding mechanism 6, after the device is installed, when the protective block 201 is pulled to the left, the stop block 304 blocks the mounting frame 302 on the L-shaped mounting block 301, preventing it from moving. When the protective block 201 is pulled to the right, the locking slot 602 and the other protective block 201 are engaged, so that the device connected to its left side forms a blocking effect on its left side, thereby preventing the protective block 201 from sliding and improving its stability after installation.

[0034] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that the rotating connection mechanism 5 includes a mounting groove 501, which is located on the left side of the bottom of the base 1. A rotating plate 502 is slidably installed in the mounting groove 501. Mounting strips 503 are fixedly connected to the front and rear sides of the rotating plate 502. The rotating plate 502 is detachably and slidably installed in the mounting groove 501 through the mounting strips 503. A rotating rod 504 is rotatably connected to the left side of the rotating plate 502 and is through it. A rotating block 505 is fixedly connected to the rear end of the rotating rod 504. An external thread groove 506 is provided at the front of the rotating rod 504. A matching connection port 507 is provided on the right side of the base 1 on the opposite side of the rotating plate 502. A through hole 508 is provided on the base 1 on the rear side of the connection port 507. An internal thread groove 509 is provided on the base 1 on the front side of the connection port 507. The rotating rod 504 is internally threadedly connected to the internal thread groove 509 through the external thread groove 506.

[0035] In use, the rotating plate 502 is slidably installed inside the mounting groove 501, and another set of devices is assembled with it. At this time, the connecting port 507 at the bottom of the rotating plate 502 is aligned with the rotating plate 502, so that the end of the rotating plate 502 is aligned with the through hole 508 and the internal thread groove 509. Then, the rotating rod 504 is slid through the through hole 508 to pass through the rotating plate 502. When the external thread groove 506 is located at the internal thread groove 509, the rotating block 505 is rotated to make the external thread groove 506 rotate in the internal thread groove 509, thereby assembling and connecting the two sets of bases 1. The assembly process is simple and improves its assembly efficiency. The rotating rod 504 can rotate the assembled device, so as to facilitate the angle adjustment of the installed base 1 according to the slope of the installation ground. The base 1 can be adjusted by ±15° around the axis of the rotating rod 504 to adapt to the change of ground slope. After the adjustment is completed, the rotating block 505 is tightened to lock the angle, which improves its practicality.

[0036] Further as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that the sliding mechanism 6 includes a sliding block 601, a bayonet 602, and a sliding cavity 603. The sliding cavity 603 is located on the left side of the protective block 201. The sliding block 601 is slidably connected to the left side of the protective block 201 through the sliding cavity 603. The bayonet 602 is located on the upper left side of the sliding block 601. On the opposite side of the bayonet 602, a matching bayonet 604 is provided on the right side of the protective block 201. The sliding block 601 is elastic.

[0037] The sliding block 601 is made of silicone material (Shore hardness 50A). During the snap-fit ​​process, it undergoes elastic deformation to fill the gap between the protective blocks 201 and form a waterproof seal. When the protective module 2 rotates with the base 1, the sliding block 601 slides adaptively in the sliding cavity 603 to maintain the airtightness of the connection.

[0038] Specifically, the two sets of protective blocks 201 are engaged by matching the locking blocks 604 with the locking slots 602. During the rotation and installation of the base 1, the protective blocks 201 can drive the sliding blocks 601 to slide in the sliding cavity 603 and deform accordingly, thereby ensuring the airtightness of the connection between the protective blocks 201 and improving its protective performance.

[0039] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the limiting mechanism 8 includes a connecting plate 801, which is slidably installed on the upper part of the base 1. The connecting plate 801 has a matching movable opening 802 on the upper part of the base 1. The connecting plate 801 is slidably installed on the upper part of the base 1 through the movable opening 802. A support component 81 is provided on the inner side of the movable opening 802 on the upper part of the base 1, which is used to match the positioning block 303 to limit the installation of the cable. There are two movable openings 802 on the upper part of the base 1. The two movable openings 802 are symmetrically opened on the left and right sides of the upper part of the base 1. The support component 81 is located between the two movable openings 802.

[0040] Further as Figure 5 As shown, it is worth noting that the support assembly 81 includes a limiting plate 811, a T-shaped block 812, a mounting cavity 813, and a spring 814. The mounting cavity 813 is located on the upper part of the base 1. The T-shaped block 812 is slidably installed within the mounting cavity 813. The limiting plate 811 is fixedly connected to the top of the T-shaped block 812 and located on the upper part of the base 1. The spring 814 is fixedly connected to the bottom of the T-shaped block 812 and is fixedly installed within the mounting cavity 813.

[0041] In use, the elastic force of the spring 814 allows the cable on the upper part of the limit plate 811 to be stably supported. Together with the positioning block 303, it can stably support and protect the cable inside the device, thereby improving its protective stability.

[0042] Specifically, the cable is placed in the groove 4 of the positioning block 303, and the connecting plate 801 is pressed down, so that the limiting plate 811 compresses the spring 814 through the T-shaped block 812 to provide initial clamping force to the cable. When the ground slope changes and the cable is displaced, the elasticity of the spring 814 causes the limiting plate 811 to dynamically adjust with the position of the cable to maintain a constant clamping force. The stiffness coefficient of the spring 814 is 5N / mm, which ensures that the limiting plate 811 can provide sufficient pressure without damaging the cable sheath.

[0043] This solution has the following working process: When this device is in use, the cable is installed and protected inside the device. When assembling the device, the rotating plate 502 is slidably installed inside the mounting groove 501, and another set of devices is assembled with it. At this time, the bottom connection port 507 is aligned with the rotating plate 502, so that the end of the rotating plate 502 is aligned with the through hole 508 and the internal thread groove 509. Then, the rotating rod 504 is slid through the through hole 508 to pass through the rotating plate 502. When the external thread groove 506 is located at the internal thread groove 509, the rotating block 505 is rotated to make the external thread groove 506 pass through the internal thread groove 509. The groove 506 rotates within the internal thread groove 509, thereby assembling and connecting the two sets of bases 1. The two sets of bases 1 can rotate through the rotating rod 504 after assembly, which facilitates the adjustment of the angle of the installed bases 1 according to the slope of the installation ground, so as to match the slope of the ground. During the rotation and installation of the bases 1, the connecting plate 801 slides on the upper part of the base 1 through the movable port 802, and the assembly allows the connecting plate 801 to slide on the upper part of the two sets of bases 1. With the rotation of the bases 1, the elastic deformation of the connecting plate 801 can ensure the rotation of the bases 1 and limit the cable.

[0044] During the assembly and installation of the device, the locking blocks 604 on the two sets of protective blocks 201 are matched with the locking slots 602 for engagement. During the rotation and installation of the base 1, the sliding block 601 can be driven by the protective blocks 201 to slide within the sliding cavity 603 and deform accordingly, thereby ensuring the airtightness of the connection between the protective blocks 201 and improving its protective performance. Through the elastic force of the spring 814, the cable on the upper part of the limiting plate 811 can be stably supported by elastic force. Together with the positioning block 303, it can stably support and protect the cable inside the device, thereby improving its stability. With the setting of the stop block 304 and the setting of the sliding mechanism 6, after the device is installed, when the protective block 201 is pulled to the left, the stop block 304 blocks the mounting frame 302 on the L-shaped mounting block 301, preventing it from moving. When the protective block 201 is pulled to the right, the locking mechanism 602 and the other protective block 201 are engaged, so that the device connected to its left side forms a blocking effect on its left side, thereby preventing the protective block 201 from sliding. This improves the stability after installation, and the installation process is simple, improving the installation efficiency.

[0045] After the device is installed, when used to protect ground wiring, the protective block 201 provides support and protection, effectively reducing the pressure on the internal cables of the device. With the setting of the limiting rod 203, the connecting block 202 is movably connected to the mounting frame 302 through the limiting rod 203 and the limiting groove 204. When the protective block 201 is subjected to pressure, the force can be transmitted to the limiting rod 203 through the connecting block 202, causing the limiting rod 203 to slide in the limiting groove 204, thereby dispersing and releasing the force on the protective block 201, thus improving the service life of the protective block 201 and enhancing its protective performance.

[0046] In summary: By using the protective module 2 on the base 1 in conjunction with the installation mechanism 3 and the rotating connection mechanism 5, the protective module 2 can be easily assembled and connected during the assembly and use of the device. This improves the assembly efficiency during use. After assembly, the two connected protective modules 2 can rotate easily, allowing for angle adjustments based on the slope of the installation site, thereby improving the device's protection efficiency for ground lines and enhancing its practicality. The sliding mechanism 6, in conjunction with the installation connection mechanism 5, allows for angle rotation of the protective module 2 during assembly and use, improving the sealing of the connection between the protective modules 2 and enhancing its waterproofness and protection of the device's interior. The limiting mechanism 8 maintains the stability of the cable within the protective module 2 according to the cable specifications of the ground lines, improving the stability of the cable protection installation within the device and enhancing its safety during use.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0048] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
