Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray installation and connection device for railway tunnels. Background Technology

[0002] Railway tunnel cable trays are important facilities used to support and lay cables inside tunnels. Their design must take into account the special characteristics of the tunnel environment (such as humidity, vibration, and limited space) to ensure the safe and stable operation of cables.

[0003] However, existing cable tray installation and connection devices for highway and railway tunnels often require placing the cable tray on the connection device before fixing the connection device. The fixing process is slow and difficult, and there is a lack of protective devices for the cables on the cable tray. The cable layout is prone to crossing and is not neat and aesthetically pleasing.

[0004] As disclosed in Chinese Patent CN221057997U, a cable tray installation and connection device for highway and railway tunnels allows for quick installation and fixation of the fixing plate, support column, and connecting block assembly via fixing holes on the fixing plate. The cable tray is then placed above the connecting block, and the plug-in pins are inserted into the plug-in holes on the connecting block. The connection is achieved through magnetic attraction and then secured with elastic clips. The entire installation process requires no screws, making it simple and quick, significantly improving installation efficiency. Furthermore, it allows for the installation of the cable tray from the bottom after this connection device is installed, greatly reducing installation difficulty. After the cable layout inside the cable tray is completed, the protective cover can be rotated, and the hemispherical clip engages with the clip hole to quickly press and fix the protective cover, thereby compressing and protecting the cables in the cable tray below, preventing cable crossing, improving aesthetics, and facilitating subsequent wiring.

[0005] However, the cable trays used in the existing technology are not convenient for pulling during the cable laying process, which can easily cause wear on the cable surface, affect the safety and service life of the cable, and can easily lead to excessive winding stress, causing cable damage.

[0025] 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. Example

[0026] The cable trays used in existing technologies are not conducive to the pulling and stretching of cables during installation, easily causing wear and tear on the cable surface, affecting cable safety and lifespan, and can also lead to excessive winding stress, causing cable damage. Please refer to [the relevant documentation / reference]. Figures 1-4The embodiment provides a railway tunnel cable tray installation and connection device, which can effectively improve the wiring effect and reduce the damage of cable wear during the wiring process. The railway tunnel cable tray installation and connection device includes a main cable tray 1, a connection device installed on the top of the main cable tray 1, a wiring device installed in the middle of the main cable tray 1, and protective devices installed on the front and back bottom of the main cable tray 1.

[0027] The wiring device includes a wiring structure and a limiting structure, with the limiting structure installed on top of the wiring structure. The wiring structure includes a mounting plate 201, with a rotating shaft 202 installed inside the top of the mounting plate 201. Rollers 203 are installed on the outer surface of the rotating shaft 202, and springs 204 are installed between adjacent rollers 203. The limiting structure includes a connecting plate 208, with a pressing plate 205 installed on the top of the connecting plate 208. Limiting pins 206 are installed at the middle of both ends of the pressing plate 205, and pressing wheels 207 are installed at the middle of the bottom surface of the pressing plate 205.

[0028] The bottom end of the mounting plate 201 is fixedly connected to the main bridge frame 1. The left and right ends of the rotating shaft 202 are connected to the mounting plate 201 through bearings. The middle part of the roller 203 is rotatably connected to the outer surface of the rotating shaft 202. The bottom end of the connecting plate 208 is fixedly connected to the main bridge frame 1. The outer surface of the limit pin 206 is threadedly connected to the internal threaded holes of the pressing plate 205 and the connecting plate 208.

[0029] By setting up the wiring device, the roller 203 and the pressing roller 207 are used to limit the cable, and the rolling of the roller 203 and the pressing roller 207 effectively reduces the damage to the cable caused by wear.

[0030] When laying cables, the rollers 203 and the rotating shaft 202 are connected by rotation, so that the cables roll during the laying process, reducing wear on the cables. The rolling of the rotating shaft 202 and the rollers 203 makes the cable laying process less strenuous. The springs 204 installed between two adjacent rollers 203 provide stress for the pulling and prevent the cables from being damaged. Then, the pressing rollers 207 work in conjunction with the rollers 203 to limit and protect the cables, preventing them from getting tangled during the laying process. After the laying is completed, the pressing plate 205 and the connecting plate 208 are connected and fixed by the limiting pins 206. Example

[0031] Based on Implementation 1, existing technologies also have problems such as water seepage from the tunnel ceiling and condensation dripping down, causing water droplets to enter the wiring structure and causing impacts, as well as dust inside the tunnel causing impacts. Please refer to [link / reference needed]. Figures 1-4This embodiment provides a railway tunnel cable tray installation and connection device that effectively solves the problems caused by water droplets and dust. The device includes a connecting rod 101, a fixing plate 102 mounted on the top of the connecting rod 101, and a guide plate 103 connected to the outer surface of the connecting rod 101. Fixing pieces 104 are fixedly installed on the front and back of the guide plate 103. The bottom end of the connecting rod 101 is fixedly connected to the middle of the top of the left and right sides of the main cable tray 1, and the bottom of the guide plate 103 is fixedly connected to the top of the left and right ends of the main cable tray 1.

[0032] The protective device includes a guide rail 301, inside which a locking block 302 is installed. A filter plate 303 is fixedly installed on the side of the locking block 302 away from the guide rail 301. Pull rings 304 are fixedly installed in the middle of the left and right sides of the filter plate 303. The guide rail 301 is fixedly installed on the front and back bottom of the main cable tray 1. The outer surface of the locking block 302 engages with the inside of the convex groove in the middle of the guide rail 301.

[0033] By setting up connecting devices and protective devices, the guide plate 103 is used to guide the water seepage or moisture condensation at the top to prevent it from affecting the interior, and the filter plate 303 effectively prevents dust particles from affecting the interior.

[0034] During the installation of the cable tray, the main cable tray 1 is installed and fixed using the connecting rod 101 and the fixing plate 102. The guide plate 103 and the fixing piece 104 are used for installation and connection, which provides an auxiliary fixing effect for the installation of the main cable tray 1. The guide groove opened on the top of the guide plate 103 effectively guides the leakage of water droplets and water vapor condensation droplets, thereby effectively preventing water flow from damaging the inside of the wiring device. At the same time, the filter plate 303 is installed by the snap-fit ​​of the clip 302 and the guide rail 301. The filter plate 303 filters the airflow inside the tunnel, preventing dust particles in the airflow from entering the inside of the wiring device, causing the connection structure to jam and affecting the normal use effect. The snap-fit ​​of the filter plate 303 with the clip 302 and the guide rail 301 makes it easy to disassemble and clean the filter plate 303, ensuring the protective effect.
