Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal engineering technology, and in particular to a protective device for underground cable laying in municipal engineering. Background Technology
[0002] In existing technologies, cable laying is a crucial component of municipal construction. Current methods typically involve first digging a rectangular pit, then inserting a rectangular pipe support frame within it, and finally placing the pipe inside. This pipe support frame structure restricts the pit to a regular rectangular shape, making excavation difficult and resulting in low construction efficiency. Furthermore, existing protective devices primarily only consider overhead protection for the cables.
[0003] Therefore, it is necessary to develop a protective device for underground cable laying in municipal engineering to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to design a protective device for underground cable laying in municipal engineering in order to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A protective device for underground cable laying in municipal engineering projects includes:
[0007] Multiple V-shaped groove plates; the tips of the V-shaped groove plates are set vertically downwards, the multiple V-shaped groove plates are connected end to end and set on the same straight line, the cable is set inside the multiple V-shaped groove plates and laid along the length of the multiple V-shaped groove plates, and the two side walls of the cable contact the two side walls of the V-shaped groove plates respectively.
[0008] Multiple crossbeams; each V-shaped groove plate has at least two parallel crossbeams at its upper end, with both ends of the crossbeams connected to the upper sides of the V-shaped groove plate, and the crossbeams are perpendicular to the length direction of the V-shaped groove plate.
[0009] Multiple top beams; the top beams are formed in an arc shape, and each V-shaped groove plate has at least two parallel top beams at its upper end, with the two ends of the top beams connected to the upper sides of the V-shaped groove plate respectively.
[0010] Multiple top plates; a top plate is laid over at least two top beams on the top of each V-groove plate, the length of the top plate being the same as the length of the V-groove plate.
[0011] The beneficial effects of this utility model are as follows:
[0012] In this application, a V-shaped channel plate is set up and a crossbeam is set on the top of the V-shaped channel plate as a stabilizing structure. Then, a top beam is set on the top of the V-shaped channel plate for laying the top plate. The top plate and the V-shaped channel plate work together to form all-round protection on the side wall of the cable, so as to prevent the cable from being squeezed and damaged by soil and stones from the side. In addition, the bottom of the V-shaped channel plate is set as a pointed end, which allows the pressure equipment to squeeze it into the soil from top to bottom during installation, avoiding the need for a more regular pit excavation, thus improving construction efficiency.

[0027] like Figure 1 and 2 As shown, a protective device for underground cable laying in municipal engineering includes:
[0028] Multiple V-shaped groove plates 1; the tips of the V-shaped groove plates 1 are set vertically downward, the multiple V-shaped groove plates 1 are connected end to end and set on the same straight line, the cable 14 is set inside the multiple V-shaped groove plates 1 and laid along the length direction of the multiple V-shaped groove plates 1, and the two side walls of the cable 14 contact the two side walls of the V-shaped groove plates 1 respectively.
[0029] Three crossbeams 2; each V-shaped groove plate 1 has three parallel crossbeams 2 at its upper end, with both ends of the crossbeams 2 connected to the upper sides of the V-shaped groove plate 1 respectively, and the crossbeams 2 are perpendicular to the length direction of the V-shaped groove plate 1.
[0030] Three top beams 3; the top beams 3 are formed in an arc shape, and each V-shaped groove plate 1 has three parallel top beams 3 at its upper end. The two ends of the top beams 3 are connected to the upper sides of the V-shaped groove plate 1 respectively; a crossbeam 2 and a top beam 3 are provided at the top of each end of the V-shaped groove plate 1, and another crossbeam 2 and a top beam 3 are provided at the middle of the upper end of the V-shaped groove plate 1.
[0031] Multiple top plates 9; a top plate 9 is laid on top of the three top beams 3 on the top of each V-shaped groove plate 1, and the length of the top plate 9 is the same as the length of the V-shaped groove plate 1.
[0032] like Figure 1-4 As shown, the protective device also includes three first bolts 8. An installation groove 4 is formed on the inner wall near the first end of the V-shaped groove plate 1. Three first through holes 6, communicating with the first end of the V-shaped groove plate 1, are formed on the inner wall of the installation groove 4. The three first through holes 6 are parallel to each other. Corresponding to the positions of the three first through holes 6, three first screw holes 7 are formed on the second end of another V-shaped groove plate 1. The first bolts 8 pass through the first through holes 6 and are screwed into the first screw holes 7. A cover plate 5 is provided on the installation groove 4, and the top of the cover plate 5 is flush with the inner wall of the V-shaped groove plate 1.
[0033] like Figure 1-2 As shown, the protective device also includes multiple second bolts. Multiple second screw holes 11 are provided on the top of the top beam 3. Corresponding to the second screw holes 11 on the top beam 3, multiple second through holes 10 are provided on the top plate 9. The second bolts pass through the second through holes 10 and are screwed into the second screw holes 11.
[0034] like Figure 5 As shown, the protective device also includes multiple clamps, which are fitted onto the cable 14. Each clamp has two rolling components on its side wall, and the two rolling components are respectively rolled to the two inner side walls of the V-groove plate 1.
[0035] like Figure 6 As shown, the rolling assembly includes a mounting bracket 15, a mounting shaft 16, and a bearing 17. The mounting bracket 15 is U-shaped and is fixedly mounted on the outer wall of the clamp. The inner ring of the bearing 17 is fitted onto the mounting shaft 16, which is installed between the open ends of the mounting bracket 15. The outer ring of the bearing 17 is in rolling connection with the inner wall of the V-groove plate 1.
[0036] like Figure 5 As shown, the clamp includes a first half clamp 12 and a second half clamp 13. The two ends of the first half clamp 12 are respectively connected to the two ends of the second half clamp 13 by a third bolt. The two connection points of the first half clamp 12 and the second half clamp 13 are respectively located above and below the cable 14.
[0037] like Figure 5As shown, the included angle between the two inner sidewalls of the V-groove plate 1 is 60°, and the perpendicular line between the axis of the cable 14 and the two inner sidewalls of the V-groove plate 1 passes through the bottom center of the two bearings 17 respectively, with the included angle between the two perpendicular lines being 120°.
[0038] Working principle: During operation, two trenches need to be excavated at both ends (start and end points) of the cable 14 laying path. The depth of these trenches is greater than the laying depth of the cable 14. Then, starting from the starting position, V-shaped channel plates 1 are laid. During laying, pressure is applied to clamp the crossbeams 2 and top beams 3 on the V-shaped channel plates 1, and then the V-shaped channel plates 1 are pressed vertically downwards, pressing open the soil on both sides of the V-shaped channel plates 1 until the V-shaped channel plates 1 reach the designed laying depth. At this point, the next V-shaped channel plate 1 is laid. Then, the first bolt 8 is placed into the installation groove 4, and the end is passed through the first through hole 6 and screwed into the first screw hole 7 of the previous V-shaped channel plate 1, completing the connection of the two V-shaped channel plates 1. After all V-shaped channel plates 1 are installed, the cable... The first end of cable 14 is fitted with a first half-hoop 12 and a second half-hoop 13, and the first half-hoop 12 and the second half-hoop 13 are connected. The bearings 17 on the first half-hoop 12 and the second half-hoop 13 respectively contact the two inner walls of the V-shaped channel plate 1. At this time, the cable 14 is fed forward. Then, clamps are fitted on the cable 14 at every end to prevent the cable 14 from drooping and directly contacting the inner wall of the V-shaped channel plate 1. Since the direct friction between the cable 14 and the V-shaped channel plate 1 in the traditional technology is changed to rolling friction, the conveying of the cable 14 is very labor-saving and can be easily completed by conveying machinery. After the cable 14 is conveyed, a top plate 9 is covered on the top beam 3 of each V-shaped channel plate 1, and then the soil is backfilled. When it is necessary to inspect a section of cable 14, simply dig up the soil on the top plate 9, unscrew the second bolt, and remove the top plate 9. Since cable 14 does not directly contact the V-shaped groove plate 1, when inspecting cable 14 later, the inspection head can be used to go directly around to the bottom of cable 14, making the inspection very convenient.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
