Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying, and in particular relates to a cable trench. Background Art

[0002] In locations with numerous cables, cable trenches or cable trays are often used for laying cables. When cable trenches are used, cables are often cluttered and overcrowded, with more cables at the top than at the bottom. This leaves no room for new cables, old cables unorganized, and discarded cables difficult to remove, creating long-term potential problems. Furthermore, excessive cable bundling and movement make subsequent maintenance and inspections difficult. This is especially true for cables that have been damaged during installation. After extended operation, damaged cables are prone to failure. Once a failure occurs, it is extremely difficult to identify the faulty cable, and surrounding cables are easily affected.

[0003] The disorderly, overcrowded, and often more cables at the top than at the bottom of a cable trench often stems from workers' limited movement within the trench and upper supports blocking lower supports. To expedite installation, workers often pull cables roughly and place them haphazardly, failing to follow design requirements. From a design perspective, the limited overall space in the trench and a lack of comprehensive consideration of the detailed installation issues can result in the trench being unable to accommodate the required number of cables, even though it was designed to.

[0004] Furthermore, cable ties often lead to excessive bundling. For one thing, the bundles are tied too close together, too many cables are tied together, and for another, cables are tangled and disordered, with cables from top to bottom, left to right, tied together. This makes it difficult to immediately identify a cable failure. Even if the faulty cable is identified, it's difficult to isolate the fault point in time, which can easily lead to extensive cable damage.

[0005] In Chinese patent CN 205693256 U, the cables are fastened by means of several adjustable buckles on the bracket, but this does not help much in the entire installation process. First, the floor height cannot be adjusted, making it difficult to adapt to changing scenarios. Second, the bracket length is fixed and cannot be adjusted. When adding or reducing cables later, the bracket will be too long or too short. Utility Model Content

[0006] The technical problem to be solved by the present invention is to provide a cable trench with a compact structure, convenient operation and high adjustment flexibility, in order to solve the problem that the existing cable trenches generally require all brackets to be welded before laying, which makes the originally limited cable trench space even narrower and the operation more restricted. To achieve the above purpose, the present invention can adopt the following technical solutions:

[0007] A cable trench comprises: a housing structure, a slide groove and a support assembly; a plurality of the slide grooves are symmetrically arranged on two opposite side walls of the housing structure in the vertical direction, at least one group of the support assemblies are detachably slidably arranged on the slide grooves in the vertical direction, and the plane direction of the support assembly is perpendicular to the length direction of the slide groove, and the cables are laid on the support assembly.

[0008] As a further improvement of the present invention, the support assembly includes a snap seat, a connecting rod and multiple support rods. The snap seat is slidably nested in the slide groove, one end of the connecting rod is fixedly connected to the snap seat, and the other end of the connecting rod is detachably connected to the support rod. Adjacent support rods are detachably connected to achieve overall length adjustment of the support assembly.

[0009] As a further improvement of the present invention, the end of the connecting rod is provided with an internal thread, one end of the support rod is provided with an internal thread, and the other end of the support rod is provided with an external thread. The connecting rod and the support rods, as well as the adjacent support rods, are all threadedly connected.

[0010] As a further improvement of the present invention, a steel ball is provided on the inner side of the buckle seat, and a plurality of positioning holes are provided on the slide groove at intervals along the vertical direction. The steel ball matches the positioning holes to achieve the connection and fixation of the support component and the slide groove.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] The cable trench of the present invention is formed by symmetrically arranging the slide grooves on the opposite side walls of the enclosure structure in the vertical direction, and then detachably sliding the support components on the slide grooves in the vertical direction, and the plane direction of the support components is perpendicular to the length direction of the slide grooves, so as to form a cable trench with a compact structure; further, the support components are set to a slidable form, so that the floor height can be adjusted according to the size of the cables, so as to reasonably utilize the space while being beneficial to the heat dissipation of the cables. It is also possible to place the support components at the top of the slide groove each time the cables are placed. After the cables are placed, the cables and the support components are moved together to an appropriate height in the enclosure structure, so as to facilitate the workers' laying, and ensure that each floor is neat and orderly, which is convenient for laying and also convenient for supervision and acceptance.

[0021] Example

[0022] like Figure 1 and Figure 2 As shown, the cable trench of the present invention comprises: an enclosure structure 1, a chute 2, and support assemblies 3. Multiple chute assemblies 2 are symmetrically arranged along the vertical direction on opposite sides of the enclosure structure 1, i.e., the chute 2 is spaced apart along the length of the enclosure structure 1. At least one set of support assemblies 3 is detachably slidably mounted on the chute 2 in the vertical direction, i.e., multiple sets of support assemblies 3 are spaced apart on the chute 2, with the planar direction of the support assemblies 3 perpendicular to the length of the chute 2. Cables are laid on the support assemblies 3, meeting the requirements for laying multiple layers of cables in the cable trench.

[0023] In this embodiment, by symmetrically setting the chute 2 on the opposite side walls of the enclosure 1 in the vertical direction, and then detachably slidingly setting the support assembly 3 on the chute 2 in the vertical direction, and the plane direction of the support assembly 3 is perpendicular to the length direction of the chute 2, a compact cable trench is formed. Furthermore, the support assembly 3 is set to a sliding form so that the floor height can be adjusted according to the size of the cable, so as to make rational use of space while facilitating heat dissipation of the cable. It is also possible to place the support assembly 3 at the top of the chute 2 each time the cable is placed. After the cables are placed, the cables and the support assembly 3 are moved together to an appropriate height in the enclosure, thereby facilitating the workers' laying and ensuring that each floor is neat and orderly, which is convenient for laying and also facilitates supervision and acceptance.

[0024] like Figure 3 As shown, the support assembly 3 includes a snap seat 31, a connecting rod 32, and a plurality of support rods 33. The snap seat 31 is slidably nested in the slide groove 2, one end of the connecting rod 32 is fixedly connected to the snap seat 31, and the other end of the connecting rod 32 is detachably connected to the support rod 33. Adjacent support rods 33 are detachably connected to each other to achieve the overall length adjustment of the support assembly 3.

[0025] like Figure 1 and Figure 2 As shown in the figure, in the cable layout, generally from top to bottom, they are: power cables (large cables 4), control cables (large cables 4), signal cables (medium cables 5), and communication cables (small cables 6). Therefore, the upper layer is mainly composed of thick power cables, and their number is generally small, while the middle and lower layers are mainly composed of control cables and signal cables, and their number is large. Therefore, the layer height, number of layers, and length of the support assembly 3 can be adjusted according to the actual number of cables and cable thickness on site.

[0026] Specifically, when there are a large number of small cables 6 (communication cables) on the bottom layer, the number of support rods 33 can be increased, thereby extending the overall length of the support assembly 3. When there are a small number of large cables 4 (power cables) on the upper layer, the number of support rods 33 can be reduced, thereby shortening the overall length of the support assembly 3. When adding or removing cables, the number of support rods 33 can be appropriately increased or decreased to match the number of cables on the current layer.

[0027] Furthermore, an internal thread 35 is provided at the end of the connecting rod 32, an internal thread 35 is provided at one end of the support rod 33, and an external thread 36 is provided at the other end of the support rod 33. The connecting rod 32 and the support rod 33, as well as the adjacent support rods 33, are all threadedly connected, which has the characteristics of simple structure, reliable connection and flexible adjustment.

[0028] To create more space for laying cables, for example, when laying small cables 6 on the bottom layer, the support assembly 3 can be installed on the top layer of the chute 2. The length of the support assembly 3 can be adjusted by installing an appropriate number of support rods 33 based on the number of cables. After all the small cables 6 on the same layer have been placed, the height of the support assembly 3 and the small cables 6 are uniformly adjusted and lowered to an appropriate height within the enclosure 1, allowing operators to lay the cables more easily and neatly. The same method is used for laying medium cables 5 and large cables 4.

[0029] like Figure 3 and Figure 4 As shown, a steel ball 34 is provided on the inner side of the snap seat 31, and a plurality of positioning holes 21 are provided on the chute 2 at intervals along the vertical direction. The steel balls 34 match the positioning holes 21 to achieve the connection and fixation between the support assembly 3 and the chute 2. By assembling the snap seat 31 and the chute 2, when the snap seat 31 needs to be raised or lowered, it only needs to gently lift the connecting rod 32 and move up or down along the chute 2 to easily reach the designated position. When it needs to stop at a certain position, it only needs to gently press the connecting rod 32 to firmly lock the steel ball 34 into the positioning hole 21 at the designated position. In this way, by adjusting the height between two adjacent layers of support assemblies 3, the floor height can be adjusted, and the space utilization rate of the cable trench can be maximized.

[0030] The cable trench of this embodiment provides a larger operating space for operators, making it convenient for operators to lay cables simply, easily and neatly, and can be laid strictly in accordance with design requirements, avoiding the situation where there are more cables at the top and less cables at the bottom.

[0031] Although the present invention is disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the spirit and technical solution of the present invention, utilize the methods and technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change, and modification of the above embodiments made in accordance with the technical spirit of the present invention, without departing from the content of the technical solution of the present invention, shall still fall within the scope of protection of the technical solution of the present invention.
