Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable support technology, specifically a novel cable trench rolling cable support device. Background Technology
[0002] Cable trenches are underground conduits used for laying and replacing power or telecommunications cables. They also serve as enclosure structures for cable installations. Cables are usually still placed on the ground in cable trenches, resulting in messy stacking of cables within the trenches. This affects cable management and maintenance. Furthermore, the poor heat dissipation of cables when they are clustered together in cable trenches can lead to excessively high cable temperatures, which can reduce the current carrying capacity of the cables and pose a fire hazard.
[0003] According to Chinese Publication No. CN219892813U, a cable trench rolling cable support device is disclosed, and Chinese Publication No. CN220156132U discloses a cable trench support. In the above two schemes, multiple rolling wheels and multiple outer protective wheels are arranged at intervals to form a grid structure with multiple grid points. Each grid point can serve as a support structure for a cable, and the grid points do not affect each other, avoiding heat accumulation caused by the accumulation of cables and ensuring that the current carrying capacity of the cable is not affected. In addition, the rolling wheels arranged vertically and horizontally can rotate relative to each other, which reduces friction when the cable is dragged, prevents damage to the cable, and extends the service life of the cable.
[0004] However, in the two schemes mentioned above, the contact area between the roller and the cable is small. As a result, when supporting a thicker cable and when the distance between two adjacent supports is large, the squeezing force of the roller on the cable is large, which poses a potential risk of excessive local pressure under static conditions. Based on this, in order to avoid this situation, a new type of cable trench rolling cable support device is provided. Utility Model Content
[0005] The purpose of this utility model is to provide a novel cable trench rolling cable support device in order to solve the problems mentioned above.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel cable trench rolling cable support device, comprising a support assembly consisting of a wall-connecting bracket, horizontal bars, a base frame, vertical bars, and a reinforcing frame. Multiple horizontal bars are vertically fixed to the front end of the wall-connecting bracket in sequence. The base frame is fixed to the bottom end of the horizontal bars. Multiple vertical bars pass through the top of the highest horizontal bar and are threadedly connected to the base frame. Multiple vertical bars are evenly arranged along the long side of the horizontal bars. The reinforcing frame is sleeved and installed on the outer sides of the upper and lower ends of the vertical bar located at the foremost end. An outer protective wheel is sleeved and installed on the outer side of the vertical bar in the middle area between two horizontal bars. A rolling wheel is sleeved and installed on the outer side of the horizontal bar in the middle area between two vertical bars.
[0007] Auxiliary support components are also provided on the outer side of the crossbar at both ends of the vertical bar. The auxiliary support components work with the rolling wheels to provide support for the cable, thereby reducing the squeezing force of the rolling wheels on the cable.
[0008] As a further embodiment of this utility model: the auxiliary support assembly includes a support plate, a through hole, an auxiliary roller, and a rotating shaft;
[0009] Two support plates are provided, and the two support plates are symmetrically distributed at the front and rear ends of the rolling wheel. The through hole is opened in the middle of the front end of the support plate and completely penetrates the rear end of the through hole. The support plate is sleeved on the outside of the crossbar through the through hole.
[0010] The auxiliary rollers are distributed between the two support plates and located on one side of the rolling rollers. The auxiliary rollers are rotatably connected to the support plates via a rotating shaft and are used to assist the rolling rollers in supporting the cable.
[0011] As a further improvement of this utility model: two auxiliary rollers are symmetrically arranged around the rolling roller, and the outer diameter of the auxiliary roller matches the outer diameter of the rolling roller.
[0012] As a further improvement of this invention, the shaft length of the auxiliary roller closest to the direction of cable insertion is greater than the shaft length of the other auxiliary roller.
[0013] As a further improvement of this utility model: a small-diameter annular portion is formed at the contact position between the outer protective wheel and the support plate, and the outer protective wheel limits the flipping angle of the support plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By setting up auxiliary support components, with auxiliary rollers and rolling rollers distributed in parallel, the weight of the cable can be effectively distributed, thereby reducing the local pressure at the contact points between the cable and the rolling rollers and auxiliary rollers, and eliminating the hidden danger of excessive local pressure under static conditions of a single rolling roller support structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-3 In this embodiment of the utility model, a novel cable trench rolling cable support device includes a support assembly 1 consisting of a wall-connecting bracket 101, a horizontal bar 102, a base frame 103, a vertical bar 104, and a reinforcing frame 105. Multiple horizontal bars 102 are vertically distributed and fixed to the front end of the wall-connecting bracket 101. The base frame 103 is fixed to the bottom end of the horizontal bars 102. The vertical bar 104 passes through multiple horizontal bars 102 sequentially from above the highest horizontal bar 102 and is threadedly connected and fixed to the base frame 103. Multiple vertical bars 104 are evenly arranged along the long side of the horizontal bars 102. The reinforcing frame 105 is sleeved and installed on the outer side of the upper and lower ends of the vertical bar 104 distributed at the front end. An outer protective wheel 2 is sleeved and installed on the outer side of the vertical bar 104 in the middle area between two horizontal bars 102. A rolling wheel 3 is sleeved and installed on the outer side of the horizontal bar 102 in the middle area between two vertical bars 104.
[0022] Auxiliary support components 4 are also provided on the outer side of the horizontal bar 102 at both ends of the vertical bar 104. The auxiliary support components 4 cooperate with the rollers 3 to provide support for the cable 5, thereby reducing the squeezing force of the rollers 3 on the cable 5.
[0023] The auxiliary support assembly 4 includes a support plate 401, a through hole 402, an auxiliary roller 403, and a rotating shaft 404;
[0024] Two support plates 401 are provided, and the two support plates 401 are symmetrically distributed at the front and rear ends of the rolling wheel 3. The through hole 402 is opened in the middle of the front end of the support plate 401 and completely penetrates the rear end of the through hole 402. The support plate 401 is sleeved on the outside of the crossbar 102 through the through hole 402.
[0025] The auxiliary roller 403 is distributed in the middle of the two support plates 401 and located on one side of the roller 3. The auxiliary roller 403 is rotatably connected to the support plate 401 through the rotating shaft 404. The auxiliary roller 403 is used to assist the roller 3 in supporting the cable 5.
[0026] There are two auxiliary rollers 403 symmetrically arranged around the rolling roller 3, and the outer diameter of the auxiliary roller 403 matches the outer diameter of the rolling roller 3.
[0027] In this embodiment: When this cable-bearing device is in use, the mesh structure composed of the roller wheel 3 and the outer sheath wheel 2 enables independent support of the cable 5, avoiding heat accumulation caused by the accumulation between the cables 5. At the same time, the rotation of the roller wheel 3 and the outer sheath wheel 2 can effectively reduce friction when the cable 5 is dragged, preventing damage to the cable.
[0028] Meanwhile, as the cable 5 passes through the mesh structure formed by the roller 3 and the outer sheath 2, the two auxiliary rollers 403 will automatically lie horizontally and adhere to the lower surface of the cable 5 under the weight of the cable 5. During the dragging of the cable 4, the auxiliary rollers 403 rotate synchronously without affecting the dragging of the cable 5. At the same time, during the later support process, the auxiliary rollers 403 are distributed parallel to the roller 3, which can effectively distribute the weight of the cable 5, thereby reducing the local pressure at the contact point between the cable 5 and the roller 3 and the auxiliary rollers 403, and eliminating the hidden danger of excessive local pressure under the static condition of a single roller support structure.
[0029] Please refer to this carefully. Figures 2-3 The length of the shaft 404 corresponding to the auxiliary roller 403 near the direction in which the cable 5 is inserted is greater than the length of the shaft 404 on the other auxiliary roller 403.
[0030] The outer guard wheel 2 has a small-diameter annular part formed at the contact position with the support plate 401, and the outer guard wheel 2 limits the flipping angle of the support plate 401.
[0031] In this embodiment: the above structure allows the weight of the rotating shaft 404 closest to the cable 5 to be greater than the weight of the other rotating shaft 404. Thus, when the auxiliary roller 403 is not subjected to external pressure, the auxiliary roller 403 closest to the cable 5 will deflect downwards under gravity, meaning the auxiliary support assembly 4 will be tilted downwards as a whole (e.g., Figure 2 This ensures that the tilt state of the auxiliary support component 4 remains consistent, facilitating the insertion of the cable 5.
[0032] After the cable 5 has completely passed over the auxiliary support assembly 4, the other raised auxiliary roller 403 will automatically return to the horizontal position under the pressure of the cable 5, that is, the two auxiliary rollers 403 will automatically fit against the bottom of the cable 5.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
