[0002] Steel grating cable trench covers are a type of sheet material used to cover cable trenches. Their main function is to protect cables and pipes, prevent people and vehicles from accidentally stepping on or damaging them, and also make the cable trenches flat and aesthetically pleasing, facilitating pedestrian and vehicle passage.
[0003] According to the patent: A telescopic steel grating cable trench cover, application number: CN201920890777.8, this patent includes a large cover plate, a small cover plate, a left support plate, and a right support plate. A large cover plate has an inner large cover plate nested inside it. The large cover plate has multiple through holes on its exterior and corresponding through holes on its inner large cover plate. The large cover plate is adjustablely fixed to the inner large cover plate via pins passing through the through holes. The end of the large cover plate away from the inner large cover plate is connected to the right support plate. A small cover plate has an inner small cover plate nested inside it. There are two large cover plates and two inner large cover plates, respectively located at the ends of the left and right support plates. Multiple small cover plates and multiple inner small cover plates are located in the middle of the left and right support plates. This cover plate can be mass-produced and can be used for cable trenches of a certain width, saving time and shortening the construction period.
[0004] The shortcomings are as follows: the fixed installation of the large cover plate and the inner plate of the large cover plate in this patent makes it impossible to disassemble and maintain. The cover plate as a whole bears the stress for a long time, and the large cover plate and the inner plate of the large cover plate are prone to damage, resulting in a decrease in the protection capability of cables and pipes. In addition, there is no reinforcing structure between the large cover plate and the inner plate of the large cover plate, and the support strength and load-bearing capacity of the cable trench cover plate are insufficient. In order to solve the above problems, this utility model proposes a telescopic steel grating cable trench cover plate. Utility Model Content

[0018] 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.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a telescopic steel grating cable trench cover, including a first U-shaped plate 1 and a second U-shaped plate 2. A first telescopic inner plate 3 is movably inserted between the two vertical plates of the first U-shaped plate 1 and the second U-shaped plate 2 respectively. A plurality of support components 4 are detachably installed between the horizontal plates of the first U-shaped plate 1 and the second U-shaped plate 2. Each support component 4 includes a first support plate 41 and a second support plate 42 arranged opposite to each other. A second telescopic inner plate 43 is movably inserted between the first support plate 41 and the second support plate 42. Locking bolts for locking the side walls of the second telescopic inner plate 43 are threadedly connected to the side walls of the first support plate 41 and the second support plate 42. Threaded heads 44 are fixedly connected to the ends of the first support plate 41 and the second support plate 42.
[0020] The middle part of the second support plate 42 and the middle part of the first telescopic inner plate 3 are provided with slots 431, and a reinforcing plate 5 is provided between the slots 431.
[0021] Furthermore, the inner sidewalls of the first U-shaped plate 1 and the second U-shaped plate 2 are each provided with a plurality of square limiting grooves 11 at equal intervals, and the ends of the first support plate 41 and the second support plate 42 are respectively inserted into the square limiting grooves 11. By inserting the first U-shaped plate 1 and the second U-shaped plate 2 into the square limiting grooves 11, the first U-shaped plate 1 and the second U-shaped plate 2 are erected and installed.
[0022] Furthermore, the outer walls of the first U-shaped plate 1 and the second U-shaped plate 2 are respectively provided with embedded grooves 12 for connecting square limiting grooves 11. The threaded head 44 passes through the first U-shaped plate 1 and the second U-shaped plate 2, and a locking nut 45 is threaded onto the threaded head 44. The two ends of the first U-shaped plate 1 and the second U-shaped plate 2 are locked by the locking nut 45 to ensure the stability of the connection of the support component 4 and strengthen the support strength of the cable trench cover.
[0023] Furthermore, the locking nut 45 is embedded in the recess 12. By locking the end of the threaded head 44 with the embedded locking nut 45, it is ensured that when multiple cover plates cover the cable trench as a whole, the cover plates are neatly aligned.
[0024] Furthermore, a pin 51 is provided at the upper middle part of the first telescopic inner plate 3, and the lower end of the pin 51 is inserted into the reinforcing plate 5. By setting the reinforcing plate 5, the load-bearing capacity of the support assembly 4 is enhanced, further preventing damage to the steel grating cable trench cover and improving its service life.
[0025] Specifically, first, replace the damaged support component 4. Remove the pin 51 on the first telescopic inner plate 3, pull out the reinforcing plate 5, then loosen the locking nut 45 on the support component 4, and then loosen the locking bolts on the first support plate 41 and the second support plate 42. Pull the first support plate 41 and the second support plate 42 towards each other to disengage them from the square limiting groove 11, and then replace them.
