Description

Technical Field

[0001] The present invention relates to the technical field of cable trays, and particularly to an anti-pulling cable protection tray. Background Art

[0002] In fields such as construction and industry, cable trays are key components for carrying and protecting cable lines. Traditional cable trays often focus on meeting the basic cable carrying function in terms of design and structure. They usually adopt a simple metal frame structure, mostly made of metal materials such as steel or aluminum, and are assembled by welding, bolt connection, etc. Such traditional cable trays have many defects.

[0003] In a relatively stable environment without external force interference, traditional cable trays can perform their duties well to ensure the orderly arrangement and safe operation of cables. However, there are many situations of external force interference in actual applications. For example, in areas with active crustal movements, strong vibrations generated by crustal movements are transmitted to the cable trays; in large industrial sites, such as ore fields, heavy machinery operates frequently, and continuous vibrations generated during its operation affect the cable trays in this area; in stormy environments, foreign object impacts, etc., cause the cables to sway. In the above situations of external force interference, due to the mostly fixed rigid structures of current cable tray structures, it is easy to pull the cables, resulting in problems such as cable breakage or damage.

[0004] In view of the above problems, there is an urgent need to develop a cable tray to address the problem of easy cable pulling and breaking under external force interference. In view of this, we propose an anti-pulling cable protection tray. Summary of the Invention

[0055] The following will describe the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0056] Please refer to Figure 1-16 , the present invention details the above technical solutions through the following embodiments:

[0057] A protective bridge frame is used to prevent the cable from being pulled and damaged under external force. It includes an installation top frame 1, which provides an installation site for construction and installation and plays a positioning role; it also includes:

[0058] A protection component 2, as shown in the structure of Figures 1-4 , includes installation bases 21 symmetrically installed on both sides below the installation top frame 1. Two symmetrically arranged side clamping units 22 are rotatably installed on the installation bases 21; among them, a connection unit 6 is horizontally slidably installed on the installation bases 21. Through the connection unit 6, a bracket 3 is detachably installed below, and a part of the bracket 3 is used to support the cable to be installed.

[0059] As shown in the structures of Figure 5 , Figure 6 , in order to enable the connection unit 6 to slide left and right, the connection unit 6 is similar to an inverted U-shaped structure clamped on the protection component 2, so as to realize the function that the connection unit 6 and the bracket 3 installed below move horizontally synchronously on the protection component 2, and the installation of the bracket 3 is realized; specifically, as shown in the structures of Figure 4 , Figure 6 , Figure 11 and Figure 16 , in this embodiment, the bracket 3 includes a U-shaped frame body 31 with clamping heads 32 connected at both ends. A clamping groove 321 is provided on the clamping head 32. A convex plate 215 is provided on the installation base 21 and between two rotating convex seats 211. In this embodiment, the connection unit 6 includes a horizontal clamping plate 61 provided with a sliding groove 611. The horizontal clamping plate 61 is slidably installed on the convex plate 215 through the sliding groove 611, so that the horizontal clamping plate 61 is clamped between the two side clamping units 22. A vertical connecting plate 62 is installed below the horizontal clamping plate 61. A clamping block 621 is provided on the vertical connecting plate 62. The connection between the connection unit 6 and the bracket 3 is realized by inserting the clamping block 621 into the clamping groove 321.

[0060] Specifically, as shown in Figure 12In the structure shown, in this embodiment, the side clamping unit 22 includes a clamping block 221 provided with a rotating shaft block 222. A pressing block 2211 for abutting against the connecting unit 6 is provided on the clamping block 221. In order to obtain the functions of rotation and reset of the clamping block 221, a ring-shaped rod 223 is installed inside the clamping block 221, and the ring-shaped rod 223 and the rotating shaft block 222 are coaxially arranged; as Figures 7-11 In the structure shown, in this embodiment, two symmetrically arranged rotating bosses 211 for rotatably installing the rotating shaft block 222 are provided on the mounting base 21. In order to obtain an effective rotating space, as Figure 10 shown, rotating cavities 212 are provided on both sides of the mounting base 21. The clamping block 221 drives the ring-shaped rod 223 to rotate coaxially, and a spring 224 is sleeved on the ring-shaped rod 223 in the rotating cavity 212. The spring maintains an elastic force for clamping the connecting unit 6 as Figure 10 shown.

[0061] In order to further obtain the reset ability of the side clamping unit 22, a reset cavity 213 as Figure 10 and Figure 11 shown is provided on the mounting base 21. Embedding grooves 214 for detachably installing the stop blocks 24 are provided at both ends of the reset cavity 213, and a reset unit 23 is detachably installed in the reset cavity 213 and located between the stop blocks 24 at both ends; as Figure 15 shown, a vertical guiding groove 242 and a rotating hole 241 which are vertically communicated are provided on the stop block 24 in this embodiment; it should be noted that a part of the ring-shaped rod 223 is always inserted in the reset cavity 213, and in the positional relationship as Figure 4 and Figure 10 shown, this is the centered state of the connecting unit 6 without external force. At this time, under the action of the spring 224, the ring-shaped rod 223 will also abut against the reset unit 23.

[0062] As Figures 13-14 shown, the reset unit 23 includes a stress block 231 with a reset pressing block 232 provided above. The stress block 231 adopts a triangular prism structure with smooth edges and corners, which can obtain a more significant extrusion and lifting effect and has a stable structure; column blocks 2311 for rotatably installing in the rotating holes 241 are provided at both ends of the stress block 231. Combining Figure 10 shown, when the cable is shaken left and right under the action of an external force, it will drive the connecting unit 6 to move horizontally through the bracket 3, and then will arbitrarily squeeze one side of the side clamping unit 22. There is deformation during this squeezing process, avoiding the situation of damaging the cable due to rigid contact.

[0063] Limit convex blocks 2321 for sliding along the vertical guiding groove 242 are provided at both ends of the reset pressing block 232, and a tension spring 233 is detachably installed between the limit convex blocks 2321 at both ends and the column blocks 2311; the stress block 231 as Figure 14The shown structure is in a V-shaped structure, and there are abutting grooves 2301 at both inclined surfaces of the force-bearing block 231, and a concave groove 2302 with an upward opening at the upper end. That is, when the side clamping unit 22 is squeezed, the annular rod 223 squeezes one side of the abutting groove 2301, causing the force-bearing block 231 to deflect along the column block 2311. However, when it deflects to either side along the column block 2311, the reset pressing block 232 will rise along the vertical guiding groove 242. At this time, the pulling force of the tension spring 233 becomes larger, providing a reset acting force to force the cable to reset, and providing an elastic deformation structure for the cable to swing again later.

[0064] It should be noted that the cable is also prone to the situation of pressing down on the cable bridge. Therefore, it is necessary to obtain a downward deformation space. In this embodiment, Figure 3 As shown in the structure, two elastic support plates 4 are symmetrically installed on the bracket 3. The elastic support plate 4 includes an S-shaped deformation plate 41 horizontally installed on the bracket 3, and an arc-shaped plate 42 fixedly connected to the upper end of the S-shaped deformation plate 41. The arc-shaped plate 42 has an upward opening and contacts the inner wall of the bracket 3. The bottom end of the S-shaped deformation plate 41 is shorter. A rubber cushion plate 5 is provided below the two S-shaped deformation plates 41. In other embodiments, an airbag can be used to replace the rubber cushion plate 5, but the rubber cushion plate 5 has stronger reliability.

[0065] The working principle of the anti-pulling cable protection cable bridge in this embodiment is as follows: Combining Figure 3 and Figure 10 As shown in the structure, when the cable is affected by an external force and is prone to damage, classified by the direction of the force, it is mainly the situation of horizontal left and right swinging and pressing down on the cable bridge. Therefore, when the cable sways left and right under the influence of an external force, the force will be transmitted to the bracket 3. If the bracket 3 has a rigid structure, the cable is easily damaged. In this application, the overall structure formed by the bracket 3 and the connecting unit 6 will provide a left and right swinging action, that is, it can obtain a horizontal displacement effect by pressing the side clamping units 22 on the left and right sides;

[0066] It needs to be explained that through the side clamping unit 22, when the external force disappears, the connecting unit 6 can always be centered and reset. This process realizes the effect of no deviation in reset, which can ensure that the displacement space in the initial state can be obtained again when affected by the next external force, thus avoiding the problem of hard friction damage caused by the rigid contact between the cable and the cable bridge.

[0067] In order to further obtain the function of keeping the connection unit 6 centered and reset, and at the same time avoid the loss of reliability of the device after the side spring 224 is damaged, a reset unit 23 is provided; when the side clamping unit 22 is squeezed, the annular rod 223 squeezes one side of the abutment groove 2301, causing the force-receiving block 231 to deflect along the column block 2311. However, when it deflects to either side along the column block 2311, the reset pressing block 232 will rise along the vertical guiding groove 242. At this time, the pulling force of the tension spring 233 becomes larger, and this process will force the reset pressing block 232 to reset, pressing the force-receiving block 231 to maintain a horizontally symmetric state, thereby promoting the reset of the side clamping unit 22, providing a structure with displacement space for the subsequent swinging of the cable again, and avoiding its being pulled horizontally;

[0068] When facing a downward force, the cable will press the elastic support plate 4 and the rubber cushion plate 5 to obtain a deformation space; in addition, in order to obtain the centering effect of the cable on the bracket 3 and avoid affecting the anti-pulling performance due to the cable not being able to reset after swinging, the arc-shaped panel 42 has an upward opening and contacts the inner wall of the bracket 3. When the cable deflects to both sides, it will press the arc-shaped panel 42 to sink downward, and the sinking will bring a greater elastic deformation force. This part of the force will cooperate with its arc-shaped structure to promote the cable to center and reset, avoiding the cable from swaying and piling up on one side, and thus obtaining a more reliable anti-pulling guarantee.

[0069] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0070] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
