Description

Technical Field

[0001] The utility model relates to the technical field of cable protection devices, and particularly relates to a cable protection device for a cable tray. Background Art

[0002] In the engineering design of cable trays, in order to prevent cables from sagging or squeezing each other due to their own weight, cable clamps are generally designed. On the one hand, cable clamps facilitate cable laying, and on the other hand, they protect the cables, providing all-round protection for the cables.

[0003] In the prior art, cables are usually fixed on cable trays through cable clamps to prevent the cables from sagging or squeezing each other due to their own weight, which affects the service life of the cables. The size of the cable clamps is adjusted by rotating the threaded rod to adapt to cables of different diameters:

[0004] I. However, in the prior art, during the adjustment of cable clamps, multiple groups of bolts need to be rotated, and it is rather troublesome to rotate them one by one, resulting in low convenience during the adjustment of cable clamps;

[0005] II. In the prior art, when cables need to be replaced and repaired, the cables need to be pulled out. Due to the long length of the cables, the extraction time is long and the efficiency is low, that is, it is not conducive to the rapid repair of the cables;

[0006] Therefore, a cable protection device for a cable tray is proposed. Content of the Utility Model

[0007] In view of this, the utility model provides a cable protection device for a cable tray to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0008] The technical solution of the utility model is realized as follows: A cable protection device for a cable tray includes a U-shaped support piece. Both ends of the U-shaped support piece are fixedly connected with fixing pieces. The lower surface of the U-shaped support piece is fixedly connected with a first connecting rod. The bottom of the first connecting rod is hinged with a support rod. The upper surface of the support rod is fixedly connected with a second connecting rod. The top of the second connecting rod is fixedly connected with a clamping block. The lower surface of the fixing piece is fixedly connected with a steel wire. One side of the steel wire is fixedly connected with a slider. The lower surface of the fixing piece is symmetrically and fixedly connected with a first spring. The bottom end of the first spring is fixedly connected with a connecting block. The upper surface of the connecting block is fixedly connected with an auxiliary rod. The auxiliary rod is located inside the first spring. The middle parts of the two connecting blocks are fixedly connected with a support plate. One side of the support plate is provided with a sliding groove. The sliding groove is slidably connected with the slider. The lower surfaces of the two connecting blocks are both fixedly connected with hinge seats. Inside the hinge seats are hinged with hinge blocks. One side of the hinge block is provided with a clamping groove. The two clamping grooves are located on both sides of the clamping block. The lower surface of the U-shaped support piece is fixedly connected with a support block. One side of the support block is symmetrically and fixedly connected with limiting rods. The two limiting rods are located on both sides of the hinge block.

[0009] Further preferably, the upper surface of the support rod is evenly provided with arc-shaped clamping grooves. One side of the U-shaped support piece close to the support rod is evenly and fixedly connected with a second spring. The lower surface of the second spring is fixedly connected with an arc-shaped support piece.

[0010] Further preferably, both the inner sides of the arc-shaped support piece and the arc-shaped clamping grooves are evenly fixedly connected with arc-shaped gaskets. The arc-shaped gaskets are in contact with the outer wall of the cable.

[0011] Further preferably, a threaded hole is provided inside the fixing piece. A fixing bolt is threadedly connected inside the threaded hole. The fixing bolt is threadedly connected with the cable tray.

[0012] Further preferably, there are multiple groups of the threaded holes. The multiple groups of threaded holes are evenly distributed.

[0013] Further preferably, the shape of the clamping groove is matched with the clamping block.

[0014] Further preferably, the bottom end of the first connecting rod is fixedly connected with an L-shaped support frame. The L-shaped support frame supports the support rod.

[0015] Due to the adoption of the above technical solutions in the embodiments of the utility model, it has the following advantages:

[0016] I. By adding an arc-shaped support piece structure to the cable protection device of the cable tray, the present utility model achieves the purpose of fixing cables of different specifications. That is, when the end of the support rod close to the second connecting rod is pushed upward, the support plate moves upward. When the hand pushing the support rod is released, the support plate moves downward, and the steel wire drives the slider to slide to the middle of the chute and get stuck. The support plate drives the hinge block to move between the limit rods, and the two groups of limit rods limit the hinge block towards the engaging block, and the two groups of engaging grooves fix the engaging block. Thus, the cable is fixed by the support rod to prevent the cable from sagging and being squeezed, which affects the service life of the cable. When the cable is relatively thin, the second spring approaches the cable, then the arc-shaped support piece approaches the cable and contacts the outer wall of the cable to fix the cable, without the need for staff to adjust one by one. Therefore, the cable protection device of the cable tray has high convenience during the process.

[0017] II. When the cable protection device of the cable tray is in use and it is desired to achieve the function of removing the cable for maintenance, the end of the support rod close to the second connecting rod is pushed upward, so that the slider slides to the bottommost position of the chute. Then, the support rod is released, and the support plate moves downward. Then, the hinge block drives the engaging groove to move downward to disengage from the limit of the limit rod, and the two groups of hinge blocks swing to both sides, so that the engaging block leaves the engaging groove. At this time, the support rod swings downward, and the staff can remove the cable, and then the cable can be replaced and repaired, with high efficiency, which is beneficial to the rapid repair of the cable.

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0026] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0027] As Figures 1-4 shown, the embodiments of the present utility model provide a cable protection device for a cable tray: including a U-shaped support piece 1, fixing pieces 2 are fixedly connected to both ends of the U-shaped support piece 1, a first connecting rod 3 is fixedly connected to the lower surface of the U-shaped support piece 1, a support rod 5 is hinged to the bottom of the first connecting rod 3, a second connecting rod 6 is fixedly connected to the upper surface of the support rod 5, an engaging block 7 is fixedly connected to the top of the second connecting rod 6, a steel wire 8 is fixedly connected to the lower surface of the fixing piece 2, a slider 9 is fixedly connected to one side of the steel wire 8, first springs 10 are symmetrically fixedly connected to the lower surface of the fixing piece 2, a connecting block 11 is fixedly connected to the bottom end of the first spring 10, an auxiliary rod 12 is fixedly connected to the upper surface of the connecting block 11, the auxiliary rod 12 is located inside the first spring 10, a support plate 13 is fixedly connected to the middle of the two connecting blocks 11, a chute 14 is opened on one side of the support plate 13, the chute 14 is slidably connected to the slider 9, hinge seats 15 are fixedly connected to the lower surfaces of the two connecting blocks 11, hinge blocks 16 are hinged inside the hinge seats 15, an engaging groove 17 is opened on one side of the hinge block 16, the two engaging grooves 17 are located on both sides of the engaging block 7, a support block 18 is fixedly connected to the lower surface of the U-shaped support piece 1, limiting rods 19 are symmetrically fixedly connected to one side of the support block 18, and the two limiting rods 19 are located on both sides of the hinge block 16.

[0028] In one embodiment, arc-shaped clamping grooves 20 are uniformly opened on the upper surface of the support rod 5, second springs 22 are uniformly fixedly connected to the side of the U-shaped support piece 1 close to the support rod 5, and arc-shaped support pieces 23 are fixedly connected to the lower surfaces of the second springs 22. Arc-shaped gaskets 21 are uniformly fixedly connected to the inner sides of the arc-shaped support pieces 23 and the arc-shaped clamping grooves 20, and the arc-shaped gaskets 21 are in contact with the outer wall of the cable. The arc-shaped gaskets 21 play a role in protecting the outer wall of the cable.

[0029] In one embodiment, threaded holes 24 are formed inside the fixing piece 2. A fixing bolt 25 is threadedly connected inside the threaded hole 24, and the fixing bolt 25 is threadedly connected to the cable bridge. Multiple groups of threaded holes 24 are provided, and the multiple groups of threaded holes 24 are evenly distributed. The multiple groups of threaded holes 24 facilitate the staff to select the position of the fixing bolt 25 according to actual needs. The shape of the engaging groove 17 cooperates with the engaging block 7. The bottom end of the first connecting rod 3 is fixedly connected to an L-shaped support frame 4, and the L-shaped support frame 4 supports the support rod 5. The L-shaped support frame 4 prevents the support rod 5 from swinging downward at a large angle, which is not conducive to the staff to ensure the neatness and beauty of the remaining cables when repairing and replacing cables.

[0030] When the utility model works: When the staff needs to protect the cable through the cable protection device of the cable bridge, the U-shaped support piece 1 and the fixing piece 2 are fixed to a suitable position of the cable bridge through the fixing bolt 25. The end of the support rod 5 close to the second connecting rod 6 is pushed upward, then the support rod 5 pushes the support plate 13 upward through the second connecting rod 6 and the engaging block 7, so that the slider 9 slides to the bottommost position of the sliding groove 14. At the same time, under the elastic performance of the steel wire 8 itself, the steel wire 8 drives the slider 9 to deflect to one side of the sliding groove 14, and at the same time the first spring 10 shortens. Then the support rod 5 is released, and the support plate 13 moves downward, then the hinge block 16 drives the engaging groove 17 to disengage from the limit of the limiting rod 19 downward, and the two hinge blocks 16 swing to both sides, so that the engaging block 7 leaves the engaging groove 17. At this time, the support rod 5 swings downward, and the staff can place the cables inside the arc-shaped clamping groove 20 in sequence. After placing, the end of the support rod 5 close to the second connecting rod 6 is pushed upward, then the support plate 13 moves upward, and the steel wire 8 drives the slider 9 to slide along the inner wall of the sliding groove 14 until the slider 9 slides to the bottommost position of the sliding groove 14. Release the hand pushing the support rod 5. Under the cooperation of the first spring 10, the support plate 13 moves downward. Under the elastic performance of the steel wire 8 itself, the steel wire 8 drives the slider 9 to slide to the middle of the sliding groove 14 and get stuck. At this time, the support plate 13 drives the hinge block 16 to move between the limiting rods 19, and the two limiting rods 19 limit the hinge block 16 toward the engaging block 7, and the two engaging grooves 17 fix the engaging block 7, so as to fix the cable through the support rod 5, prevent the cable from sagging and squeezing, and affect the service life of the cable. At the same time, when the cable is relatively thin, the second spring 22 approaches the cable, then the arc-shaped support piece 23 approaches the cable and contacts the outer wall of the cable to fix the cable, without the need for the staff to adjust one by one, so that the cable protection device of the cable bridge has high convenience during the process. When the cable needs to be repaired, the end of the support rod 5 close to the second connecting rod 6 is pushed upward to open the support rod 5, and the cable can be replaced and repaired with high efficiency, which is conducive to the rapid repair of the cable.

[0031] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model.
