Description

Technical Field

[0001] The utility model relates to the technical field of cable troughs, in particular to an inner wall wear-resistant SMC cable trough structure. Background Art

[0002] During railway construction, it is often necessary to lay power transmission cables and communication signal cables, which are generally laid along the railway line. To extend the service life of the cables and provide good protection, they are usually placed in dedicated cable troughs, and SMC materials are currently mostly used to make such cable troughs.

[0003] Although cable troughs made of SMC materials are widely used in railway construction to provide protection for power transmission cables and communication signal cables, in actual use, friction may still occur between the cables and the inner wall of the cable trough. This friction may cause wear of the cable's outer protective layer, thereby shortening the cable's service life. Utility Model Content

[0007] A U-shaped support block is fixedly connected to the middle of the bottom side of the tank body;

[0008] The first and second pressure plates are sequentially engaged with the U-shaped grooves on the U-shaped support block from top to bottom. The second pressure plate is engaged with the trough body and the U-shaped support block. The trough body, the second pressure plate and the trough cover are fixedly connected by a number of bolts;

[0009] The bottom of the trough body, the bottom of the first pressing plate, and the top and bottom of the second pressing plate are all provided with arc grooves that fit the surface of the cable.

[0010] As a further description of the above technical solution:

[0011] There are multiple groups of sliding grooves on both sides of the trough body, and a second fixed groove extends at the bottom of the sliding groove along the length direction of the trough body. A first limiting groove extends along the length direction of the bottom end of the U-shaped groove on the U-shaped support block, and the second fixed groove and the first limiting groove have the same extension direction. Second fixing blocks that are adapted to the sliding groove and the second fixed groove are fixedly connected on both sides of the second pressure plate, and the second pressure plate cooperates with the first limiting groove.

[0012] As a further description of the above technical solution:

[0013] A first fixed groove extends along the length direction of the groove body at the top of the slide groove, and the vertical positions of the first fixed groove and the second fixed groove correspond to each other. First fixed blocks adapted to the first fixed groove are fixedly connected on both sides of the first pressure plate, and the bolts are fixedly connected to the groove body after passing through the groove cover and the first fixed block.

[0014] As a further description of the above technical solution:

[0015] A U-shaped pressing block is fixedly connected to the bottom side of the first pressing plate near the first limiting groove, and a through groove is opened at one end of the second pressing plate to accommodate the vertical ends of the U-shaped pressing block. The U-shaped groove at the bottom of the U-shaped pressing block abuts against the surface of the second pressing plate.

[0016] As a further description of the above technical solution:

The trough body 1 and the trough cover 2 are fixedly connected by a number of bolts 3. The U-shaped support block 11 is fixedly connected to the middle part of the bottom side of the trough body 1. The first pressing plate 4 and the second pressing plate 5 are sequentially matched with the U-shaped groove on the U-shaped support block 11 from top to bottom. The bottom of the trough body 1, the bottom of the first pressing plate 4, and the top and bottom of the second pressing plate 5 are all provided with arc grooves 502 that fit the cable surface. The cable is laid on the arc groove 502 between the two groups of pressure plates and the arc groove 502 between the second pressure plate 5 and the trough body 1. The cable between the second pressure plate 5 and the trough body 1 is first clamped by the second pressure plate 5, the trough body 1 and the U-shaped support block 11, and then the first pressure plate 4 is clamped with the cable between it and the second pressure plate 5 by the bolts 3 fixed between the trough cover 2, the first pressure plate 4 and the trough body 1. At the same time, the second pressure plate 5 is positioned and the cable is clamped in multiple places along the length direction of the trough body 1, so as to realize the position positioning of the cable in the trough body 1, prevent friction between the cable and the inner wall of the trough body 1, reduce the wear of the outer protective layer of the cable, and improve the service life of the cable.

[0033] Specifically, such as Figure 3 As shown, multiple groups of slide grooves 101 are provided on both sides of the trough body 1. A second fixed groove 103 extends along the length direction of the trough body 1 at the bottom of the slide groove 101. A first limiting groove 1101 extends along the length direction of the U-shaped groove on one end of the bottom side of the U-shaped support block 11. The second fixing groove 103 and the first limiting groove 1101 extend in the same direction. Second fixing blocks 51 that are adapted to the slide grooves 101 and the second fixing grooves 103 are fixedly connected on both sides of the second pressure plate 5. The second pressure plate 5 cooperates with the first limiting groove 1101. First, the second fixing blocks 51 are aligned with the slide groove 101, and the second pressure plate 5 is pushed downward to the bottom. Then, the second pressure plate 5 is pushed toward the direction of the first limiting groove 1101. The second fixing blocks 51 are engaged with the second fixing groove 103, and the second pressure plate 5 is engaged with the first limiting groove 1101, thereby tightening the cable between the second pressure plate 5 and the trough body 1. The structure is simple and easy to operate, and no additional fasteners are required for connection.

[0034] Specifically, such as Figure 4As shown, a first fixing groove 102 extends along the length of the trough body 1 at the top of the slide 101. The vertical positions of the first fixing groove 102 and the second fixing groove 103 correspond to each other. First fixing blocks 41 that adapt to the first fixing groove 102 are fixedly connected on both sides of the first pressure plate 4. The bolts 3 pass through the trough cover 2 and the first fixing blocks 41 and are fixedly connected to the trough body 1. First, align the first fixing blocks 41 and the first fixing groove 102, push the first pressure plate 4 downward to the bottom, then cover the trough cover 2. Then, screw the bolt 3 in the middle above the first fixing groove 102 to connect the trough cover 2, the first fixing block 41 and the trough body 1, and tighten the cable between the first pressure plate 4 and the second pressure plate 5. The structure is simple and easy to operate, and only one fastener, the bolt 3, is required.

The U-shaped groove at the bottom of the U-shaped stopper 42 abuts against the surface of the U-shaped support block 11, and the first pressure plate 4 is fixedly connected to a U-shaped pressure block 45 on one side of the bottom near the first limiting groove 1101. A through groove 501 is opened at one end of the second pressure plate 5 to accommodate the vertical ends of both sides of the U-shaped pressure block 45 to pass through, and the U-shaped groove at the bottom of the U-shaped pressure block 45 abuts against the surface of the second pressure plate 5. After the second pressure plate 5 cooperates with the first limiting groove 1101, a gap is left between the other end of the second pressure plate 5 and the vertical end on the other side of the U-shaped support block 11. During the cooperation between the first pressure plate 4 and the slot body 1, the U-shaped stopper 42 enters the gap to limit the second pressure plate 5 to prevent the second pressure plate 5 from moving in the length direction of the slot body 1. At the same time, the vertical ends on both sides of the U-shaped pressure block 42 pass through the through groove 501 and press on the second pressure plate 5, supporting the other end of the first pressure plate 4, improving the stability of the first pressure plate 4, and improving its compression effect on the cable.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, a movable groove 4201 is formed on the U-shaped stopper 42, and a limit plate 43 is rotatably mounted in the movable groove 4201 via a rotating shaft 44. A second limit groove 1102 is formed on the vertical end of the other side of the U-shaped support block 11, which cooperates with the limit plate 43. By rotating the rotating shaft 44, the limit plate 43 is driven to abut against the second limit groove 1102, vertically locking the first pressure plate 4 and the tank body 1, ensuring that the first fixing block 41 accurately matches the first fixing groove 102, so that the bolts pass through the tank cover 2 and the first fixing block 41 and are fixedly connected to the tank body 1.
