DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figure 1-Figure 5As shown, a trough-type cable tray in one embodiment of the present invention includes a trough-type cable tray body 1, and slide rails 103 are integrally formed on both sides of the trough-type cable tray body 1. Bending portions 201 are bent on both sides of the cover plate 2, and the bending portions 201 can slide on the slide rails 103, so that the cover plate 2 can be slidably installed on the top of the trough-type cable tray body 1 to encapsulate the top of the trough-type cable tray body 1.

[0032] Among them, such as Figure 1 and Figure 2 As shown, the longitudinal section of the slide rail 103 is in an arc shape, and the bent portion 201 is also bent in an arc shape, which can effectively reduce the resistance during the sliding process and prevent jamming.

[0033] Preferably, a plurality of assembly holes 101 are provided on the trough type bridge body 1 , and the trough type bridge body 1 can be conveniently installed at a designated position through the plurality of assembly holes 101 .

[0034] Furthermore, a plurality of heat dissipation holes 102 are provided on the trough type bridge main body 1 , which facilitate heat dissipation of the cables inside the trough type bridge main body 1 and ensure safe use of the cables inside the trough type bridge main body 1 .

[0035] A transverse shaft 3 is welded and fixed at both ends of the interior of the trough-type bridge body 1 , and a plurality of groups of position-limiting support assemblies 4 are rotatably connected to the transverse shaft 3 .

[0036] Among them, such as Figure 3 As shown, the multiple groups of position-limiting support assemblies 4 include multiple groups of support rods 401 , each of which is fixedly mounted with a sleeve 402 at one end, and the support rods 401 are rotatably connected to the horizontal shaft 3 through the sleeve 402 .

[0037] A wire clamping frame 403 is fixedly installed on the support rod 401. The wire clamping frame 403 has an opening. The cable can be clamped into the interior of the wire clamping frame 403 through the opening, thereby limiting the cable and making it difficult for the cable to swing freely inside the trough-type bridge frame body 1, so that the cables can be neatly arranged inside the trough-type bridge frame body 1.

[0038] A protective pad 4031 is bonded and fixed to the inner wall of the wire clamping frame 403. Preferably, the protective pad 4031 can be a rubber pad, which can protect the cable and prevent the cable surface from being worn.

[0039] A pair of brackets 404 are integrally formed at one end of the support rod 401 away from the horizontal axis 3. Through the pair of brackets 404, the rotating support rod 401 can pick out the cable from the inside of the trough-type bridge body 1, and the support rod 401 can support the cable so that the cable can be inspected and maintained outside the trough-type bridge body 1.

[0040] Preferably, adjacent support rods 401 have different lengths, that is, adjacent cables have different heights after being supported, so that when multiple groups of cables are lifted at the same time, different cables can be easily identified, thereby reducing the possibility of operational errors.

[0041] Specifically, when it is necessary to inspect and maintain the cables inside the trough-type bridge body 1, the specified cables can be removed from the corresponding wire clamping frame 403 first, and then the cables can be placed between a pair of brackets 404 while rotating the support rod 401, so that the cables can be picked out and supported from the inside of the trough-type bridge body 1, which is convenient for the staff to operate.

[0042] Each of the pair of brackets 404 is provided with a fixing structure for securing the cable. The fixing structure includes a fixing slot 4041 formed on the bracket 404. The inner wall of the fixing slot 4041 is provided with a screw hole. A fastening bolt 4042 is screwed into the inner portion of the screw hole. By rotating the fastening bolt 4042, the cable can be compressed and fixed in the interior of the fixing slot 4041, thereby securing the cable.

[0043] A knob is fixed at one end of the fastening bolt 4042, and the fastening bolt 4042 can be conveniently rotated manually through the knob, thereby enhancing operability.

[0044] Specifically, if the cable inside the trough-type bridge body 1 is severely damaged and needs to be cut off for maintenance or replacement, after the cable is cut off, its ends can be fixed inside a pair of fastening bolts 4042 to prevent the ends of the cable from moving after the cable is cut off, so as to ensure safe maintenance or replacement of the cable.

[0045] like Figure 4 and Figure 5 As shown, a slot 301 is provided on the outer wall of the horizontal axis 3, a spring 302 is fixedly installed inside the slot 301, a top block 303 is fixedly installed on the spring 302, and the top block 303 is slidably inserted into the slot 301 at one end close to the spring 302, and the top block 303 can elastically expand and contract inside the slot 301.

[0046] A positioning groove 4021 is provided on the inner wall of the sleeve 402, and the top block 303 matches the positioning groove 4021. When the support rod 401 is flipped and erected, the top block 303 can just enter the inside of the positioning groove 4021 to limit the sleeve 402, so that the support rod 401 can be automatically fixed after being flipped and erected without the need for manual support.

[0047] Preferably, the upper half of the top block 303 is hemispherical. When the support rod 401 is rotated with force, the top block 303 can automatically retract into the inside of the slot 301, causing the support rod 401 to lose its fixation so that it can be flipped back into the inside of the trough-type bridge frame body 1.

[0048] Specifically, such as Figure 4 Combine Figure 5 As shown, in the natural state, the support rod 401 lies flat inside the groove type bridge main body 1, at this time the top block 303 will be in close contact with the inner wall of the sleeve 402, increase the friction resistance of the sleeve 402 rotation, prevent the support rod 401 inside the groove type bridge main body 1 from shaking randomly. When carrying out cable maintenance work, after turning over the support rod 401 to stand up, the upper half of the top block 303 can be automatically clamped into the inside of the positioning groove 4021, realize the blocking and limiting of the sleeve 402, so that the support rod 401 can be automatically fixed after standing up, prevent the support rod 401 from falling during operation.

[0049] When in use, the cables passing through the inside of the groove type bridge main body 1 are respectively clamped and fixed on the plurality of groups of wire clamping frames 403, realizing the neat arrangement of the cables inside the groove type bridge main body 1, when the cables need to be maintained, the cover plate 2 is slid open, then the specified cable is taken off from the wire clamping frame 403, and the support rod 401 is turned over, so that the support rod 401 props up the cable from the inside of the groove type bridge main body 1, thereby the cable is maintained outside the groove type bridge main body 1, if the cable needs to be cut off, then the two ends of the cut-off cable can be respectively fixed in the inside of a pair of fixing grooves 4041, realizing safe and convenient cable maintenance.

[0050] Compared with the prior art, the groove type cable bridge of the utility model can limit and fix the cables inside the groove type bridge main body 1 through the wire clamping frames 403 on the plurality of groups of support rods 401, make the cables arrange neatly inside the groove type bridge main body 1, and through the rotation of the support rod 401, the cables can be picked out from the inside of the groove type bridge main body 1 and fixed, thereby the cable maintenance work can be carried out above the groove type bridge main body 1, facilitate the operation of the staff, and bring great convenience to the cable maintenance work.

[0051] It is apparent for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, the scope of the utility model is defined by the appended claims instead of the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims should be included in the utility model.
