Technical Field

[0001] The utility model relates to the field of prefabricated cable trenches, in particular to a prefabricated lightweight thin-walled cable trench. Background Technique

[0002] A cable trench is a device used for laying underground to protect the laying of cables. The existing cable trenches are relatively long, so it is not convenient for laying operations. Therefore, prefabricated cable trenches are needed. Among them, the "Prefabricated Cable Trench Unit and Cable Trench" disclosed in the application number "CN202222271607.6" is also an increasingly mature technology. In the prefabricated cable trench unit of the utility model, the trough body further includes a plurality of cable racks and a plurality of fixing pieces. Part of the cable racks are arranged on the inner wall of the side plate through the fixing pieces, and the fixing pieces are arranged on the cable racks to fix the cable racks, so that the cable racks will not swing or shake randomly, and the cable racks can be used to place cables. However, during the use of this cable trench, there are still the following defects: Although the cable trench can be conveniently laid through the cooperation of the trough body and the cable rack and other structures, the above structures are simple and have a relatively heavy self-weight. Therefore, it will increase the labor intensity of the staff during laying. Based on this, it is necessary to provide a cable trench with a relatively light self-weight and convenient laying. In addition, it is not convenient to adjust the height of the cable during laying as needed. Based on this, it is necessary to provide a cable trench that is convenient for laying cables and convenient for height adjustment. Content of the Utility Model

[0004] To achieve the above object, the utility model provides a prefabricated lightweight thin-walled cable trench, including an assembly component and an installation component;

[0005] Among them, the assembly component includes cable trench blocks. Two limiting grooves are opened at one end of the cable trench block, and two limiting strips are fixedly connected to the other end of the cable trench block. Both of the two limiting strips are fitted with the limiting grooves. A weight-reducing groove is opened inside the cable trench block;

[0006] The installation component includes two mounting plates installed on both sides of the inner wall of the cable trench block. First mounting grooves are formed inside the two mounting plates. Second mounting grooves are formed on both sides inside the first mounting grooves. A lead screw is rotatably connected inside the first mounting groove.

Two limiting strips 103 are fixedly connected to the other end of the cable trench block 101. Both of the two limiting strips 103 are fitted with the limiting grooves 102. A weight-reducing groove 104 is opened inside the cable trench block 101;

[0026] The installation component 200 includes two mounting plates 201 installed on both sides of the inner wall of the cable trench block 101. First mounting grooves 202 are opened inside the two mounting plates 201. Second mounting grooves 203 are opened on both sides inside the first mounting grooves 202. A lead screw 204 is rotatably connected inside the first mounting grooves 202. Guide rods 205 are installed inside the second mounting grooves 203. Lifting blocks 206 are connected to the side surfaces of the lead screw 204 and the guide rods 205. A support plate 207 is fixedly connected to one side of the lifting block 206. A number of springs 208 are equidistantly installed inside the support plate 207. The upper ends of the number of springs 208 are fixedly connected with bumps 209. Two sliding shells 210 are sleeved on the side surface of the support plate 207. Arc-shaped blocks 220 are fixedly connected to the upper ends of the two sliding shells 210.

[0027] In a specific embodiment, the assembled component 100 and the installation component 200 are configured to not only reduce the self-weight of the cable trench block 101, thereby reducing the labor intensity of the staff, but also facilitate the laying of the cable trench block 101, thereby improving the laying convenience. At the same time, through the mutual cooperation of the above structures, the cables can be erected and the distance and height between the cables can be adjusted. Therefore, the practicability of the cable trench can be enhanced. During use, the presence of the weight reduction groove 104 can reduce the self-weight of the cable trench block 101. At the same time, the two limiting strips 103 at one end of several cable trench blocks 101 are snapped into the limiting groove 102 at one end of another cable trench block 101, so that the cable trench blocks 101 can be assembled and laid. During use, first, the cables pass through several arc-shaped blocks 220, and then the sliding shell 210 is controlled to move along the support plate 207, so that the bumps 209 at different positions are snapped into the concave holes 232, so that the positions of the arc-shaped blocks 220 can be adjusted, and then the cable spacing can be adjusted. Subsequently, the screw rod 204 is rotated, and the lifting block 206 can be controlled to lift along the first installation groove 202 and the second installation groove 203 in cooperation with the guide rod 205, so as to adjust the height of the support plate 207, so as to enhance the practicability of the cable trench.

[0029] In a specific embodiment, when several cable trench blocks 101 are spliced and laid, the drainage grooves 111 can be spliced with each other, so that drainage operation can be achieved. The first screw holes 112 facilitate the installation of the mounting plate 201 and improve the installation stability.

[0030] Please refer to Figures 4-6 , side plates 211 are fixedly connected to both sides of the mounting plate 201, and a plurality of second screw holes 212 are provided on the surface of the side plates 211. Second bolts 213 are threadedly connected to the interiors of the plurality of second screw holes 212 and the first screw holes 112.

[0031] In a specific embodiment, when the second bolts 213 are threadedly connected to the interiors of the second screw holes 212 and the first screw holes 112, the connection strength between the mounting plate 201 and the cable trench block 101 can be enhanced. At the same time, the mounting plate 201 can be disassembled by removing the second bolts 213.

At this time, by rotating the lead screw 204 in cooperation with the third threaded hole 221 and the guide hole 222, the stability of the lifting block 206 during lifting can be improved.

[0034] Please refer to Figures 4-6 , a plurality of fixing holes 231 are equidistantly formed at the upper end of the support plate 207. A plurality of springs 208 are installed inside the fixing holes 231. A concave hole 232 is formed at the upper end of the inner wall of the sliding shell 210. The convex block 209 is clamped inside the concave hole 232.

[0035] In a specific embodiment, the fixing holes 231 facilitate the installation and fixation of the springs 208. By clamping the convex block 209 inside the concave hole 232, the sliding shell 210 can be easily installed and fixed, thereby limiting the arc-shaped block 220.

[0036] Please refer to Figures 4-6 , sliding grooves 241 are formed on both sides of the support plate 207. Sliding strips 242 are fixedly connected to both sides of the inner wall of the sliding shell 210. The sliding strips 242 are slidably connected inside the sliding grooves 241.

[0038] Please refer to Figures 4-6 , the arc-shaped block 220 is made of aluminum alloy.

[0039] In a specific embodiment, the arc-shaped block 220 made of aluminum alloy can enhance the compressive strength and extend the service life of the arc-shaped block 220.

[0040] Working principle: During use, the presence of the weight reduction groove 104 can reduce the self-weight of the cable trench block 101. Subsequently, the two limiting strips 103 at one end of several cable trench blocks 101 are clamped inside the limiting groove 102 at one end of another cable trench block 101, and the cable trench blocks 101 can be assembled and laid. When installing the cable, first insert the cable into several arc-shaped blocks 220 and control the sliding shell 210 to move along the support plate 207, so that the convex blocks 209 at different positions are clamped inside the concave holes 232, thereby adjusting the position between the arc-shaped block 220 and the cable. Then, rotate the lead screw 204 and cooperate with the guide rod 205 to control the lifting block 206 to lift along the first installation groove 202 and the second installation groove 203, thereby adjusting the height of the support plate 207 and enhancing the practicability of the cable trench.
