Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, and more specifically, to a trough type cable bridge. Background Art

[0002] In the electrical engineering and construction industries, trough-type cable trays are important facilities for installing, supporting and protecting cables. However, the existing technology has a series of shortcomings in the internal structure design, installation convenience and maintenance friendliness of cable trays. These problems not only affect the efficiency of cable management, but also pose a potential threat to the safety and durability of the facilities.

[0003] First of all, many existing trough-type cable trays adopt a relatively simple internal structure and lack an effective cable separation and fixing mechanism. This design makes the cables installed inside the tray often in a messy state and lacks the necessary organization and management. The random stacking of cables not only increases the risk of electrical interference, but also may cause physical damage between cables, reducing the service life of the cables and the reliability of the system. In addition, the lack of effectively managed cable systems also brings inconvenience to future expansion and maintenance, and increases operation and maintenance costs.

[0004] Secondly, the existing technology mostly uses the traditional connection method of bolts and nuts in the splicing and installation of bridge frames and cover plates. Although this connection method can provide a stable fixing effect to a certain extent, it performs poorly in terms of rapid installation, especially in projects that require rapid deployment of cable wiring. The traditional bolt and nut connection method is cumbersome and inefficient, which not only prolongs the construction time of the project, but also increases labor costs.

[0005] Furthermore, for the maintenance of cables in the bridge, the existing design often requires the removal of the cover from the bridge. This process requires the use of special tools in many cases, and even requires the use of violent removal with great force in some designs. This not only increases the complexity and labor intensity of the maintenance work, but also increases the risk of damage to the facility itself. Especially in the case of emergency maintenance or rapid response, the complex and time-consuming disassembly process greatly limits the maintenance efficiency and affects the stable operation and safety of the system.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a trough-type cable tray, which has the following beneficial effects:

[0019] 1. The cable clamping device realizes unified management and fixation of cables through the combination of components such as lead screw, slide plate and cable tie plate. This design allows the cables to be placed in the wiring trough in an orderly manner as required, and the cable tie plate can be symmetrically moved by rotating the lead screw, so that the cables can be stably clamped in the cable tie trough.

[0032] The wire harness plates 8 are symmetrically arranged as a group, and there are multiple groups of wire harness plates 8. The lead screw 4 connected below each group of wire harness plates 8 is a section, and opposite threads are arranged at both ends of each section of the lead screw 4, and the multiple sections of threads are arranged in a linear array.

[0033] A hand wheel 13 is provided on the outside of the bridge frame 1 , and the hand wheel 13 is connected to one end of the lead screw 4 . A handle 14 is provided on one side of the hand wheel 13 , and the handle 14 is fixedly arranged on one side of the hand wheel 13 .

[0034] A rubber plate 15 is provided on one side of the cable tie plate 8 , and the rubber plate 15 is detachably mounted on the one side of the cable tie plate 8 .

[0035] A boss 16 is disposed on the outer side of the release sleeve 11 , and the boss 16 is fixedly disposed on the outer side of the release sleeve 11 .

[0036] A limiting plate 17 is disposed on one side of the release sleeve 11 , a push spring 18 is disposed on one side of the limiting plate 17 , and the other end of the push spring 18 is connected to the clamping sleeve 22 .

[0037] In this embodiment, when the device needs to be used to manage and install cables, cables of uniform specifications are placed in the wiring trough 2, and then placed in the corresponding cable duct 6 according to the model and usage requirements, and then the handwheel 13 is rotated through the handle 14, and the handwheel 13 drives the screw 4 to rotate. Since each section of the screw 4 is provided with opposite threads, when the screw 4 rotates, the single group of symmetrically arranged cable duct plates 8 will move relatively inward, thereby uniformly clamping the cables into the cable duct 6.

When the release sleeve 11 moves to the top end, the push spring 18 applies a pre-tightening force to the release sleeve 11 to prevent the release sleeve 11 from rotating easily. Then the quick-release assembly can be removed from the outside of the cover plate 3, and then the cover plate 3 can be removed to maintain and adjust the cables in the wiring groove 2. The setting of the boss 16 can mainly increase the friction force on the outside of the rotating sleeve.

[0038] See also Figure 3-5 As an implementation method of a slot-type cable tray for a quick-installation mechanism: the quick-installation mechanism includes a rolling ball 19, a clamping groove 20, a clamping column 21, a clamping sleeve 22 and a through groove 23. The clamping column 21 is arranged on both sides of the bridge 1, and the clamping sleeve 22 is detachably sleeved on the outside of the clamping column 21. The through groove 23 is opened on the side wall of the clamping sleeve 22, and the clamping groove 20 is opened on the side wall of the clamping column 21. The rolling ball 19 can be movably installed in the through groove 23, and one end of the rolling ball 19 is clamped into the clamping groove 20.

[0039] The through groove 23 is composed of a transverse cylindrical structure and a hemispherical structure.

[0040] More specifically, when it is necessary to fix the cover plate 3 to the top of the bridge frame 1, first place the cover plate 3 to the top of the bridge frame 1, then ensure that the release sleeve 11 has moved to the position closest to the limit plate 17, and the release sleeve 11 has compressed the push spring 18, and then the plug-in sleeve is fitted on the outside of the plug-in column. During this process, the ball 19 is squeezed by the clamping column 21 and will enter the release groove 12 again, and then the release sleeve 11 is rotated in the corresponding direction, the release sleeve 11 will drive the limiting ball 10 to slide in the spiral groove 9, and then the limiting ball 10 will drive the release sleeve 11 to move downward along the spiral groove 9, so that the inner wall of the release sleeve 11 squeezes the ball 19, so that the ball 19 rolls in the through groove 23, and then the ball 19 will be engaged in the clamping groove 20, so that the clamping sleeve 22 is stably engaged to the outside of the clamping column 21, and then the cover plate 3 is stably fixed to the top of the bridge frame 1.

[0041] In summary, when the overall equipment is in use or running: when the equipment needs to be used to manage and install cables, cables of uniform specifications are placed in the wiring trough 2, and then placed in the corresponding cable duct 6 according to the model and usage requirements, and then the handwheel 13 is rotated through the handle 14, and the handwheel 13 drives the screw 4 to rotate. Since each section of the screw 4 is provided with opposite threads, when the screw 4 rotates, a single group of symmetrically arranged cable ties 8 will move relatively inward, thereby uniformly clamping the cables in the cable duct 6. The rubber plate 15 arranged in the cable duct 6 can prevent the edge of the cable ties 8 from scratching the cables, and the rubber plate 15 has a certain degree of ductility, which can clamp the cables more tightly. When the cables inside the bridge frame 1 need to be adjusted or maintained, the release sleeve 11 is rotated. The release sleeve 11 drives the limiting ball 10 to slide in the spiral groove 9. Due to the special structural setting of the spiral groove 9, the limiting ball 10 will drive the release sleeve 11 to spirally rise along the spiral groove 9. At the same time, the release sleeve 11 will cooperate with the limiting plate 17 to compress the push spring 18, and then the release sleeve 11 will drive the release groove 12 to move, so that the position of the release groove 12 is aligned with one of the components in the quick-release assembly, thereby releasing the quick-release assembly. When the release sleeve 11 moves to the top, the push spring 18 applies a pre-tightening force to the release sleeve 11 to prevent the release sleeve 11 from rotating easily. Then the quick-release assembly can be removed from the outside of the cover plate 3, and then the cover plate 3 can be removed to maintain and adjust the cables in the wiring groove 2. The setting of the boss 16 can mainly increase the friction force on the outside of the rotating sleeve.

[0042] When it is necessary to fix the cover plate 3 to the top of the bridge frame 1, first place the cover plate 3 to the top of the bridge frame 1, then ensure that the release sleeve 11 has moved to the position closest to the limit plate 17, and the release sleeve 11 has compressed the push spring 18, and then the plug-in sleeve is fitted on the outside of the plug-in column. During this process, the ball 19 is squeezed by the clamping column 21 and will enter the release groove 12 again, and then the release sleeve 11 is rotated in the corresponding direction, the release sleeve 11 will drive the limiting ball 10 to slide in the spiral groove 9, and then the limiting ball 10 will drive the release sleeve 11 to spirally move down along the spiral groove 9, so that the inner wall of the release sleeve 11 squeezes the ball 19, so that the ball 19 rolls in the through groove 23, and then the ball 19 will be engaged in the clamping groove 20, so that the clamping sleeve 22 is stably engaged to the outside of the clamping column 21, and then the cover plate 3 is stably fixed to the top of the bridge frame 1.
