Description

Technical Field

[0001] This invention relates to the field of cable trench prefabricated components, and more particularly to a cable trench prefabricated component for cable installation and the cable trench thereof. Background Technology

[0002] Cable trenches are underground conduits used for laying and replacing power or telecommunications cables. They also serve as the enclosure structure for the cables being laid. These trenches come in various shapes, including rectangular, circular, and arched. Cable supports, typically made of metal, are installed inside the trench and are fixed to the trench walls by welding or screws. The cables are supported by the supports and kept at a certain distance from the trench bottom. Cable trenches are generally constructed of concrete or brick.

[0003] Its top is covered with a cover plate.

[0004] Currently, cable mounting racks are generally installed manually. The manual installation of cable mounting racks relies on manual measurement, calibration, installation, and debugging processes. Due to the narrow space inside the cable trench and the large number of cable mounting racks, it is often difficult to ensure that the front and rear cable mounting racks are completely on the same horizontal line during manual installation. Installing cable mounting racks in this way will cause the installed cables to be subjected to varying degrees of stress in the vertical direction, thereby affecting the service life and stability of the cables.

[0005] Therefore, a prefabricated cable trench component and its cable trench for cable installation are proposed to solve the problem that manual installation makes it difficult to ensure that the front and rear cable mounting frames are on the same horizontal line. Summary of the Invention

[0014] Preferably, the mounting bracket is a U-shaped base, and the mounting bracket is provided with a positioning unit for positioning the cable.

[0015] Preferably, the positioning unit includes several partitions and clamps. The partitions are arranged in the mounting frame and are evenly distributed along the length of the mounting frame. A positioning area is formed between two adjacent partitions. A top plate is hinged to the mounting frame via a hinge shaft. The clamps are paired together and abut against each other, and are arranged on the top plate corresponding to the positioning area. The top plate is connected to the mounting frame via a snap-fit ​​unit.

[0016] Preferably, the top plate has an opening corresponding to the positioning area, the two abutting clamps are slidably connected in the opening, and the opposite side of the two abutting clamps and the part near their bottom end is set as an inclined surface.

[0023] 3. The cable trench prefabricated component for cable installation, through the set positioning unit, can conveniently and quickly position the cable in the positioning area on the mounting frame. At the same time, during the process of the top plate flipping and abutting against the partition, the elastically set clamp can position the cable in the positioning area, improving the positioning effect. In addition, the elastically set clamp can also adapt to cables of different specifications, further improving the adaptability of the positioning unit.

[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1:

[0040] Please see Figure 1-7 This embodiment of a cable trench prefabricated component for cable installation includes a trench component 1. A mounting plate 3 is provided on the side wall of the trench component 1, and a mounting frame 2 is provided between two mounting plates 3 to support the cable. The mounting plate 3 facing the mounting frame 2 has several mounting grooves 4 of equal length along the height direction of the trench component 1. Corresponding to the mounting grooves 4, the mounting plate 3 has several insertion holes 8 of equal height along the length direction of the trench component 1, connected to the mounting grooves 4. The mounting frame 2 has a connecting block 7 on its side corresponding to the mounting grooves 4, located within the mounting grooves 4. A connecting hole 71 is provided within the connecting block 7 corresponding to the insertion hole 8, and a rod 5 is inserted into the insertion hole 8, passing through the connecting hole 71.

[0041] In application, before cable installation, the connecting block 7 on the mounting bracket 2 is placed into the mounting slot 4, and then the mounting bracket 2 is pushed to move the connecting block 7 within the mounting slot 4. After the connecting block 7 is moved until the connecting hole 71 is aligned with the insertion hole 8, the insertion rod 5 is inserted along the insertion hole 8. The insertion rod 5 will pass through the insertion hole 8 and the connecting hole 71, thereby fixing the connecting block 7 in the mounting slot 4. With the fixing of the connecting block 7, the mounting bracket 2 used to support the cable can also be installed in the trench 1. As the previous mounting bracket 2 is installed in the trench 1, another mounting bracket 2 can be installed in the same mounting slot 4 in the same manner as described above. By restricting the installation position of the two mounting brackets 2 through the mounting slot 4, the two mounting brackets 2 installed in the trench 1 can be on the same horizontal line, thereby making the subsequent cable more evenly stressed during installation and improving the service life and stability of the installed cable.

[0042] Example 2:

[0043] The basic content is from Example 1, the difference being:

[0044] Please see Figure 1-3In this embodiment, the height of the connecting block 7 is equal to the height of the inner cavity of the mounting groove 4. The connecting block 7 moves linearly along its length direction within the mounting groove 4. The inner diameter of the insertion hole 8 is equal to that of the connecting hole 71. The inner diameter of the insertion hole 8 is adapted to the outer diameter of the insertion rod 5. The height of the insertion rod 5 is equal to the height of the mounting plate 3. The height of the mounting plate 3 is equal to the height of the inner cavity of the groove 1.

[0045] In application, during the installation of cables of different specifications in the groove 1, the distance between the upper and lower distributed mounting brackets 2 can be easily and quickly adjusted through the set mounting slots 4. This allows one mounting bracket 2 to accommodate cables of different specifications on adjacent mounting brackets 2, avoiding the limitation caused by the inability to adjust the distance between two adjacent mounting brackets 2, which would prevent the installation of cables of different specifications. At the same time, during the installation of the mounting bracket 2, the inner diameter of the matching insertion hole 8 and the connecting hole 71 and the outer diameter of the insertion rod 5 can improve the stability of the connecting block 7 installed in the mounting slot 4, thereby improving the stability of the mounting bracket 2. Furthermore, the insertion rod 5, which is the same height as the mounting plate 3, can accommodate the connecting block 7 installed in different mounting slots 4, so as to accommodate the installation of cables of different specifications.

[0046] Furthermore, the top surface of the mounting plate 3 has a groove 31 corresponding to the insertion hole 8. The groove 31 is connected to the insertion hole 8, and the inner diameter of the groove 31 is larger than the inner diameter of the insertion hole 8. The insertion rod 5 is located in the groove 31. When it is necessary to repair the groove 1 or the cable, the groove 31 corresponding to the insertion rod 5 can easily remove the insertion rod 5 from the insertion hole 8, so that the mounting bracket 2 can be separated from the groove 1. At this time, the groove 1 or the cable can be repaired.

[0047] It is known that the design of the socket 8, the plug rod 5, the connecting block 7 and other structures improves the ease of installation and disassembly of the mounting bracket 2 and reduces the difficulty of construction.

[0048] Example 3:

[0049] The basic content is from Example 1, the difference being:

[0050] Please see Figure 4-7In this embodiment, the mounting frame 2 is a U-shaped seat. The mounting frame 2 is provided with a positioning unit 6 for positioning the cable. The positioning unit 6 includes several partitions 61 and clamps 62. Several partitions 61 are arranged inside the mounting frame 2 and are evenly distributed along the length of the mounting frame 2. A positioning area 21 is formed between two adjacent partitions 61. A top plate 63 is hinged to the mounting frame 2 through a hinge shaft. Several clamps 62 are paired together and abutted, and are arranged on the top plate 63 corresponding to the positioning area 21. The top plate 63 is connected to the mounting frame 2 through a snap-fit ​​unit. An opening 64 is opened on the top plate 63 corresponding to the positioning area 21. Two abutting clamps 62 are slidably connected in the opening 64. The opposite side of the two abutting clamps 62 and the part near its bottom end are provided with a slope 65. The clamps 62 are elastically connected to the inner wall of the opening 64. The bottom end of the clamps 62 abuts against the inner bottom wall of the mounting frame 2.

[0051] In application, after the mounting bracket 2 is installed in the trench 1, the cable can be placed on the mounting bracket 2. During installation, rotate the top plate 63 to open the positioning area 21, and then place the cable in the positioning area 21. After the cable is placed, rotate the top plate 63 so that the top plate 63 abuts against the partition plate 61. As the top plate 63 moves, the clamping plate 62 also moves synchronously and gradually moves into the positioning area 21. When the clamping plate 62 enters the positioning area 21, the inclined surface 65 on the clamping plate 62 will contact the surface of the cable. As the top plate 63 moves continuously, it squeezes the clamping plate 62 through the cable, causing the two clamping plates 62 that have entered the positioning area 21 to move toward the corresponding partition 61. After the top plate 63 rotates to abut against the top surface of the partition 61, the elastic force generated by the elastically connected clamping plates 62 can clamp the cable in the positioning area 21 and position the cable in the positioning area 21. At the same time, the clamping plates 62 elastically set on the top plate 63 can also position cables of different specifications, improving adaptability.

[0052] It is known that, through the positioning unit 6, the clamp 62 can complete the positioning of the cable during the process of the flip clamp 62 abutting against the partition 61, so that the cable can be positioned in the positioning area 21 between the two partitions 61 quickly and efficiently, thereby improving the positioning efficiency of the cable.

[0053] It should be noted that after the flip-up clamp 62 abuts against the partition 61, the top plate 63 can be fixed to the mounting bracket 2 by the snap-fit ​​unit.

[0054] Furthermore, a connecting rod 67 is provided along the length of the opening 64, and a clamping plate 62 is sleeved on the connecting rod 67. The clamping plate 62 is connected to the inner wall of the opening 64 by a spring 66. Through the spring 66 and the connecting rod 67, the clamping plate 62 can be more stable when the opening 64 moves, and the clamping plate 62 can clamp and position the cable under the action of the elastic force of the spring 66.

[0055] Furthermore, the bottom surface of the clamping plate 62 is designed as an arc surface; when the top plate 63 squeezes and positions the cable through the clamping plate 62, the arc surface can prevent damage to the surface of the cable and improve the protection effect.

[0056] Example 4:

[0057] The basic content is from Example 1, the difference being:

[0058] Please see Figure 8 In this embodiment, the top surface of the groove 1 is fitted with a cover plate 9. The groove 1 includes two half-parts 11 that abut against each other. A connecting piece 12 is fixed at the abutment of one half-part 11, and a slot 13 is opened at the abutment of the other half-part 11 corresponding to the connecting piece 12. The connecting piece 12 is inserted into the slot 13. A screw is vertically provided on the connecting piece 12, and the screw is threadedly connected to the half-part 11 corresponding to the slot 13.

[0059] In application, by splicing the two halves 11, the connecting piece 12 can be moved into the slot 13. Then, the two halves 11 are assembled into the trench 1 by screws. After assembly, the mounting bracket 2 and the cable can be installed step by step. Finally, after the cable is installed, the cover plate 9 is snapped onto the trench 1. At this time, the entire cable installation is completed. The trench 1 is spliced ​​from the two halves 11. The spliced ​​trench 1 is easy to transport and handle. In actual use, it also has the advantages of high flexibility, convenient and quick installation. In addition, the spliced ​​trench 1 also facilitates subsequent maintenance work.

[0060] Example 5:

[0061] The basic content is from Example 1, the difference being:

[0062] Please see Figure 1 In this embodiment, a cable trench for cable installation includes multiple trench components 1 as described in Embodiment 1 above, and each trench component 1 is sequentially spliced ​​along its length.

[0063] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
