Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and specifically relates to a trough-type cable tray. Background Technique

[0002] At present, traditional cable troughs are all made by stamping and bending a whole steel plate into a trough with three sides, and then using a cover plate type cover. When laying cables, it is very difficult to close the cover of the cable trough because the cover plate and the cable trough are separated. When covering the cover plate, both ends must be aligned to buckle it, which will reduce the work efficiency.

[0003] The utility model with the publication number CN212726337U proposes a trough-type cable tray, which includes a long strip, a hinge and a cover plate. The longitudinal section of the long strip trough is U-shaped. One end of the long strip trough is connected to the cover plate through a hinge. A number of cable outlets are arranged at equal intervals on the three sides of the long strip trough. The longitudinal section of the cover plate is a bridge arch shape with a high middle and low sides. Due to the integrated connection method of the long strip trough and the cover plate in this utility model, it is very easy to cover the cover plate after laying the cables. Since a number of cable outlets are arranged at equal intervals on the three sides of the long strip trough, the cables can be led out at the most suitable positions without being limited by the length of the long strip trough. Since a cable trench is arranged at the bottom of the long strip trough and a cable fixing clip is arranged on the cable trench, the cables are effectively fixed. This utility model can improve the work efficiency, improve the convenience of bridge construction and reduce the installation difficulty.

[0004] However, the above-mentioned prior art still has the following deficiencies in use: The cover plate is connected to the long strip trough through a hinge. Due to the connection effect of the hinge, the cover plate is always in a connected state with the long strip trough. Due to the weight of the cover plate itself, the weight during the high-altitude installation of the long strip trough increases, which further increases the installation difficulty. Moreover, when laying cables in the long strip trough, the space occupied after the cover plate is opened is relatively large, which will also affect the progress of cable laying in the long strip trough.

[0005] Therefore, the utility model provides a trough-type cable tray. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a trough-type cable tray to solve the problems raised in the above background technique. The utility model ensures the convenience of high-altitude laying and installation of the trough while meeting the requirement that the cover plate can be quickly docked with the trough, as well as the convenience of cable laying in the cable trough.

[0007] To achieve the above object, the present utility model is realized through the following technical solutions: A trough-type cable tray, comprising a trough frame and a cover plate integrally formed by bending, the cross-sections of the trough frame and the cover plate are both U-shaped, through holes are provided on the three side walls of the trough frame at equal intervals along the length direction of the trough frame, a plurality of U-shaped plates are fixedly connected to one side outside the trough frame near the top and arranged at equal intervals, the open end of the U-shaped plate is arranged away from the side wall of the trough frame, one end of the cover plate is fixedly connected with a U-shaped rod, and the cross bar on the U-shaped rod and the inner groove of the U-shaped plate are in plug-in movable connection.

[0008] Further, the number of U-shaped rods on the cover plate is at least two.

[0009] Further, a rotating sleeve is sleeved on the cross bar, and the outer diameter of the rotating sleeve is less than or equal to the width of the U-shaped inner groove of the U-shaped plate.

[0010] Further, a rubber sleeve is fixedly sleeved on the outside of the rotating sleeve, and the rubber sleeve is in interference fit with the U-shaped inner groove of the U-shaped plate.

[0011] Further, it further includes a pull rod, right-angle bending hooks are provided at both ends of the pull rod, right-angle inner flanges are provided at both ends of the mouth of the trough frame, positioning holes are provided on the upper end surface of the right-angle inner flange at equal intervals along the length direction, and the positioning holes are in plug-in fit with the right-angle bending hooks.

[0012] Further, a plurality of partition plates arranged along the width direction are welded at the bottom inside the trough frame, and the partition plates are also equally spaced along the length direction of the trough frame.

[0013] Further, a protective rubber sleeve is sleeved outside the partition plate.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the present utility model, by fixedly arranging U-shaped plates at a position near the top on one side outside the trough frame, and then fixedly connecting a U-shaped rod that can be hooked to the U-shaped plates on one side outside the cover plate, under the limitation of the U-shaped rod and the U-shaped plates, the cover plate can accurately and quickly cover the top opening of the trough frame after rotation. When the cover plate is not needed, the U-shaped rod can be controlled to disengage from the U-shaped plate so that the cover plate and the trough frame are separated, which is convenient for the separate high-altitude laying installation of the trough frame and the laying of the cables inside it.

[0016] In the present utility model, by opening positioning holes on the end face of the mouth of the trough frame, and then setting a pull rod with right-angle bending hooks at both ends, the width of the mouth of the trough frame is in an approximately constant state through the plug-in connection of the right-angle bending hooks and the positioning holes, which not only improves the anti-deformation strength of the trough frame but also ensures the smoothness of the docking between the cover plate and the trough frame.

Specific embodiments

[0021] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a trough - type cable bridge, including a trough frame 1 and a cover plate 2 formed by integral bending. One trough frame 1 corresponds to multiple cover plates 2. The multiple cover plates 2 are arranged on the top of the trough frame 1 to close the mouth of the trough frame 1. The cross - sections of the trough frame 1 and the cover plate 2 are both U - shaped. Wire - passing holes 11 are provided on the three side walls of the trough frame 1 at equal intervals along the length direction of the trough frame 1.

[0023] In this technical solution, on one side outside the trough frame 1, a plurality of U - shaped plates 3 are fixedly connected near the top and arranged at equal intervals. The open end of the U - shaped plate 3 is arranged away from the side wall of the trough frame 1. The U - shaped plate 3 and the trough frame 1 are welded. One end of the cover plate 2 is fixedly connected with a U - shaped rod 4. The number of U - shaped rods 4 on the cover plate 2 is at least two. The cross bar 41 on the U - shaped rod 4 and the inner groove of the U - shaped plate 3 are in plug - in movable connection. That is to say, after the U - shaped rod 4 is inserted into the U - shaped plate 3, it can rotate. The cover plate 2 can directly cover the top opening of the trough frame 1 by rotating with the cross bar 41 located in the U - shaped rod 4 as the rotation axis without manual alignment operation. When the cover plate 2 is not in use, the cover plate 2 can be opened and then the cross bar 41 can be held by hand to disengage from the U - shaped plate 3. At this time, the cover plate 2 and the trough frame 1 are separated.

[0024] In this embodiment, the cross bar 41 is sleeved with a rotating sleeve 411. The outer diameter of the rotating sleeve 411 is less than or equal to the width of the U - shaped inner groove of the U - shaped plate 3. This setting can reduce the rotational friction between the cross bar 41 and the U - shaped plate 3.

[0025] Further, a rubber sleeve 4111 is fixedly sleeved outside the rotating sleeve 411. The rubber sleeve 4111 is in interference fit with the U-shaped inner groove of the U-shaped plate 3. The function of the rubber sleeve 4111 is to improve the docking stability between the rotating sleeve 411 and the U-shaped plate 3 and reduce the difficulty of manually rotating the cover plate 2. That is to say, without the rubber sleeve 4111, the rotating sleeve 411 is likely to slide outwards from the U-shaped plate 3 when closing the cover plate 2.

[0026] This embodiment further includes a pull rod 5. Right-angle bending hooks 51 are provided at both ends of the pull rod 5. Right-angle inner flanges 12 are provided at both ends of the mouth of the trough rack 1. Positioning holes 121 evenly distributed along the length direction are formed on the upper end surface of the right-angle inner flange 12. The positioning holes 121 are inserted and matched with the right-angle bending hooks 51. Since the trough rack 1 is made by bending a metal plate, its mouth lacks a reinforcing component and is prone to problems such as necking or mouth expansion deformation. By providing the pull rod 5, the width of the mouth of the trough rack 1 can be effectively guaranteed, which not only helps the laying of cables, but also ensures the smoothness of covering the mouth of the trough rack 1 by the cover plate 2.

[0027] In this embodiment, a plurality of partition plates 6 arranged along the width direction are welded at the bottom inside the trough rack 1. The function of the partition plates 6 is to separate different types of cables, avoid cable cross-winding, and improve the neatness of laying various cables inside the trough rack 1. The partition plates 6 are also equally spaced along the length direction of the trough rack 1.

[0028] Further, a protective rubber sleeve 61 is sleeved outside the partition plate 6. The function of the protective rubber sleeve 61 is to protect the cables and prevent the partition plate 6 from directly wearing the cables.

[0029] Working principle: After the trough rack 1 is erected in the air, various cables are laid inside the trough rack 1, and then different cables are placed in the isolation grooves formed by a plurality of partition plates 6. After the cable laying is completed, hold the cover plate 2 and insert the rotating sleeve 411 thereon into the U-shaped plate 3. Under the resistance of the rubber sleeve 4111, the cross bar 41 can be stably located at the bottom of the groove of the U-shaped plate 3. Then manually rotate the cover plate 2. Supported by the cross bar 41, the cover plate 2 can accurately cover the trough rack 1. When deformation occurs at the mouth of the trough rack 1, making it difficult to cover the corresponding cover plate 2, at this time, take the pull rod 5 and manually shape the mouth of the trough rack 1, and then insert the right-angle bending hooks 51 at both ends of the pull rod 5 into the corresponding positioning holes 121. At this time, the problem of local deformation of the trough rack 1 can be effectively eliminated, and finally cover the cover plate 2.

[0030] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only includes an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
