Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to an engineering cable trench anti-collapse support device that is easy to maintain. Background Technology

[0002] Cable trenches are underground structures used for laying and protecting cables. They are mainly used for the installation of power, communication, and network cables and are an indispensable part of urban infrastructure and industrial facilities. To ensure the stability of cable trenches, support devices are needed to prevent them from collapsing.

[0003] Most current cable trench anti-collapse support devices are relatively simple in design, often being integrated units. Local damage requires complete removal of the device for repair or replacement, which affects the device's lifespan, makes maintenance inconvenient, and may increase operating costs.

[0004] Therefore, in view of the inconvenience of maintenance of existing support devices, an engineering cable trench anti-collapse support device that is easy to maintain can be designed. Through the split installation method, it is easy to disassemble and assemble, and local repairs or replacements can be carried out according to the actual damage location, which improves the convenience of maintenance operations, ensures the stability of the cable trench, and reduces the cost of device use, thereby effectively enhancing the practical value of the device. Utility Model Content

[0005] To overcome the problem that most cable trench anti-collapse support devices are designed as a single unit, and partial damage requires complete removal of the device for repair or replacement, which is inconvenient during maintenance and may increase operating costs, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a cable trench anti-collapse support device for easy maintenance, comprising an L-shaped bracket, a reinforcing rib, a first clamping plate, a sliding groove, a pressure plate, clamping strips, a second clamping plate, a clamping groove, a clamping block, and an installation groove. The inner side of the L-shaped bracket is provided with a reinforcing rib, one end of which is perpendicular to the horizontal plane, and the other end of which is parallel to the horizontal plane. A first clamping plate is provided on one side of the vertical end of the reinforcing rib. Two sets of sliding grooves are symmetrically opened on the inner side of one end of the L-shaped bracket. A pressure plate is provided above the sliding grooves. Two sets of clamping strips are symmetrically arranged at the bottom end of the pressure plate. A second clamping plate is provided at the bottom end of the clamping strips. A clamping groove is opened at the bottom end of the sliding groove. A clamping block is provided on one side of the planar end of the reinforcing rib. An installation groove is opened on the inner side of the other end of the L-shaped bracket.

[0007] Preferably, by setting reinforcing ribs to enhance the support of the L-shaped bracket, the first clamping plate slides along the slide groove, allowing the clamping block to flexibly engage with the mounting groove, thereby fixing one end of the reinforcing rib to the L-shaped bracket. Moving the pressure plate, the clamping strip is embedded into the slide groove, causing the second clamping plate to engage between the first clamping plate and engage with the clamping groove, thus fixing the other end of the reinforcing rib to the L-shaped bracket as well. This facilitates the easy installation and removal of the reinforcing rib, enabling localized repair or replacement based on the actual damaged location, improving the convenience of maintenance operations, ensuring the stability of the cable trench, reducing the cost of using the device, and enhancing the practical value of the device.

[0008] Preferably, the reinforcing ribs are inclinedly arranged between the L-shaped brackets, and two sets of the first card plates are arranged in pairs. The first card plates are slidably connected to the sliding grooves, and the card strips are connected to the sliding grooves.

[0009] Preferably, the second card plate is fitted between the two sets of first card plates, the bottom end of the second card plate is fitted and connected to the card slot, and the card block is fitted and connected to the mounting slot.

[0010] Preferably, two sets of mounting plates are symmetrically arranged on the bottom surfaces of both ends of the L-shaped bracket. A first mounting hole is opened on one side of the L-shaped bracket, and the first mounting hole is connected to the slide groove. A first mounting hole is also opened on one side of the first and second clamping plates.

[0011] Preferably, a first screw is rotatably connected to the inner side of the first mounting hole, a first rotating plate is provided at the top of the first screw, a locking ring is rotatably connected to the outer side of the bottom end of the first screw, and a second rotating plate is provided on the outer side of the locking ring.

[0012] Preferably, one end of the L-shaped bracket is provided with a second mounting hole, which is connected to the mounting groove. A second mounting hole is also provided on one side of the block.

[0013] Preferably, a second screw is rotatably connected to the inner side of the second mounting hole, and a third rotating plate is provided at the top end of the second screw.

[0014] The beneficial effects of this utility model are:

[0015] When inspecting and maintaining the support device, slide the first clamping plate along the slide groove to allow the clamping block to flexibly engage in the installation groove, thereby fixing one end of the reinforcing rib to the L-shaped bracket. Then, move the pressure plate to embed the clamping strip into the slide groove, so that the second clamping plate is clamped between the first clamping plates and embedded into the clamping groove, thereby fixing the other end of the reinforcing rib to the L-shaped bracket as well. This facilitates the easy disassembly and assembly of the reinforcing rib, solving the problem that most cable trench anti-collapse support devices are mostly integrated designs, and partial damage requires complete removal of the device for repair or overall replacement, which is inconvenient during maintenance and may increase the cost of use. This enhances the practical value of the device. Attached Figure Description

[0022] Please see Figure 2 and Figure 3 This utility model provides an embodiment: an engineering cable trench anti-collapse support device that is easy to maintain, including an L-shaped bracket 1, reinforcing ribs 2, a first clamping plate 3, a sliding groove 4, a pressure plate 5, clamping strips 6, a second clamping plate 7, a clamping groove 8, a clamping block 9, and an installation groove 10. The inner side of the L-shaped bracket 1 is provided with reinforcing ribs 2, one end of which has a cut perpendicular to the horizontal plane, and the other end of which has a cut parallel to the horizontal plane. The reinforcing ribs 2 are inclinedly arranged between the L-shaped brackets 1. A first clamping plate 3 is provided on one side of the vertical end of the reinforcing rib 2, and two sets of first clamping plates 3 are arranged in pairs. Two sets of sliding grooves 4 are symmetrically opened on the inner side of one end of the frame 1. The first clamping plate 3 is fitted and slidably connected with the sliding groove 4. A pressure plate 5 is provided above the sliding groove 4. Two sets of clamping strips 6 are symmetrically arranged at the bottom end of the pressure plate 5. The clamping strips 6 are fitted and connected with the sliding groove 4. A second clamping plate 7 is provided at the bottom end of the clamping strip 6. The second clamping plate 7 is fitted between the two sets of first clamping plates 3. A groove 8 is opened at the bottom end of the sliding groove 4. The bottom end of the second clamping plate 7 is fitted and connected with the groove 8. A clamping block 9 is provided on one side of the flat end of the reinforcing rib 2. An installation groove 10 is opened on the inner side of the other end of the L-shaped bracket 1. The clamping block 9 is fitted and connected with the installation groove 10.

[0023] Please see Figure 1and Figure 4 In this embodiment, two sets of mounting plates 101 are symmetrically arranged on the bottom surfaces of both ends of the L-shaped bracket 1. A first mounting hole 801 is opened on one side of the L-shaped bracket 1. The first mounting hole 801 is connected to the slide groove 4. A first mounting hole 801 is also opened on one side of the first clamping plate 3 and the second clamping plate 7. The mounting plate 101 is fixed in the cable trench by means of ground nails or bolts, thereby fixing the L-shaped bracket 1 in the cable trench.

[0024] The inner thread of the first mounting hole 801 is rotatably connected to a first screw 802. The top end of the first screw 802 is provided with a first rotating plate 803, and the outer thread of the bottom end of the first screw 802 is rotatably connected to a locking ring 804. The outer side of the locking ring 804 is provided with a second rotating plate 805. The mounting position of the first screw 802 is determined by the first mounting hole 801. After aligning the first mounting holes 801 on the first clamping plate 3 and the second clamping plate 7, the first rotating plate 803 is rotated to screw the first screw 802 into the first mounting hole 801. Then, the second rotating plate 805 is rotated to drive the locking ring 804 to rotate and screw the locking ring 804 into the other end of the first screw 802, thereby flexibly fixing one end of the reinforcing rib 2.

[0025] Please see Figure 1 and Figure 3 In this embodiment, one end of the L-shaped bracket 1 is provided with a second mounting hole 1001, which is connected to the mounting groove 10. The side of the locking block 9 is also provided with a second mounting hole 1001. The inner side of the second mounting hole 1001 is threadedly connected to a second screw 1002. The top end of the second screw 1002 is provided with a third rotating plate 1003. The installation position of the second screw 1002 is determined by the second mounting hole 1001. The third rotating plate 1003 is rotated to drive the second screw 1002 to rotate and screw the second screw 1002 into the second mounting hole 1001, thereby flexibly fixing the other end of the reinforcing rib 2.

[0026] When installing the device, use ground nails or bolts to fix the mounting plate 101 in the cable trench, thereby fixing the L-shaped bracket 1 in the cable trench. Then move the reinforcing rib 2 to embed the first clamping plate 3 into the sliding groove 4, so that the first clamping plate 3 slides along the sliding groove 4 to the bottom. At this time, the clamping block 9 is inserted into the mounting groove 10.

[0027] Subsequently, the pressure plate 5 is moved to make the clip 6 embed into the groove 4, the bottom end of the second clip 7 is inserted into the groove 8, the first rotating plate 803 is rotated to screw the first screw 802 into the first mounting hole 801, and the second rotating plate 805 is rotated to screw the locking ring 804 into the other end of the first screw 802, locking one end of the reinforcing rib 2 onto the L-shaped bracket 1.

[0028] Finally, rotate the third rotating plate 1003 to screw the second screw 1002 into the second mounting hole 1001, and lock the other end of the reinforcing rib 2 onto the L-shaped bracket 1.

[0029] During maintenance, if the reinforcing rib 2 is found to be damaged, rotate the third rotating plate 1003 to unscrew the second screw 1002, then rotate the second rotating plate 805 to unscrew the locking ring 804 from the first screw 802, rotate the first rotating plate 803 to unscrew the first screw 802, pull the pressure plate 5 to remove the retaining strip 6 from the slide groove 4, and then remove the reinforcing rib 2 for maintenance or replacement.

[0030] Through the above steps, the support of the L-shaped bracket 1 is enhanced by setting the reinforcing rib 2. The first clamping plate 3 is slid along the slide groove 4, so that the clamping block 9 can be flexibly inserted into the mounting groove 10, thereby fixing one end of the reinforcing rib 2 to the L-shaped bracket 1. The pressure plate 5 is moved, and the clamping strip 6 is embedded into the slide groove 4, so that the second clamping plate 7 is clamped between the first clamping plate 3. The second clamping plate 7 is embedded into the clamping groove 8, so that the other end of the reinforcing rib 2 is also fixed on the L-shaped bracket 1. The reinforcing rib 2 can be easily disassembled and installed, so that local repair or replacement can be carried out according to the actual damaged location, improving the convenience of maintenance operations, ensuring the stability of the cable trench, and reducing the cost of using the device.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
