Description

Technical Field

[0001] The utility model belongs to the technical field of shaft bridges, and in particular relates to a cable laying device for shaft bridges. Background Art

[0002] In high-rise buildings, the vertical transmission of electric energy and electrical signals is greater than the horizontal transmission. Large-section wires and a large number of cables are laid in the vertical direction. Therefore, in order to solve the channel and layout of longitudinal cables, plug-in busbars, and cable trays in the building, a certain cross-section of the shaft is often reserved from the bottom to the top in high-rise buildings, which is the electrical shaft.

[0003] In the existing cable laying device of the shaft bridge, due to the small space of the shaft, the cables can only be laid by using the vertical upper elbow as the support point. In this laying method, the support points are always at one or two corners. As more cables are laid, cables begin to cross from the starting point. When the cables are tied, they cross and overlap layer by layer, which is time-consuming and laborious to sort out. Finally, the cables in the bridge are crossed and chaotic.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0031] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0033] See also Figure 1-Figure 9 As shown, the utility model is a cable laying device for a shaft bridge, comprising a first mounting component 1, a plurality of pulleys 2 are arranged on the circumferential surface of the first mounting component 1, and limit components 3 are rotatably installed at both ends of the pulley 2, and one end of the limit component 3 close to the central axis is arranged on the circumferential surface of the first mounting component 1, and a second mounting component 4 is slidably installed in the inner cavity of the first mounting component 1, and a gear bar 5 is fixedly installed at one end of the second mounting component 4 close to the first mounting component 1, and a clamping component 6 is fixedly installed at one end of the first mounting component 1 close to the second mounting component 4, and the clamping component 6 and the gear bar 5 are clamped with each other, and the ends of the first mounting component 1 and the second mounting component 4 away from each other stop on the inner wall of the shaft bridge 7.

[0034] When in use, first place the first mounting assembly 1 and the second mounting assembly 4 on the inner wall of the shaft bridge 7 respectively, then adjust the length between the second mounting assembly 4 and the first mounting assembly 1 according to the length of the inner cavity of the shaft bridge 7. After the adjustment, turn the clamping assembly 6 fixedly mounted on the first mounting assembly 1 and the gear bar 5 fixedly mounted on the second mounting assembly 4 by hand to engage them with each other. After the engagement, the self-locking inside the clamping assembly 6 makes it possible for no sliding movement to occur between the clamping assembly 6 and the gear bar 5 at this time, and no relative sliding will occur between the first mounting assembly 1 and the second mounting assembly 4 on each side, so that the pulley 2 on the first mounting assembly 1 and the limit assembly 3 are installed. Install it on the shaft bridge 7, adjust the positions of several limit assemblies 3 according to the installation position of each cable, and then use a wrench to rotate the several limit assemblies 3 on the first installation assembly 1, and then the several components inside the limit assembly 3 will converge toward the outer wall of the first installation assembly 1 until they are completely limited by the first installation assembly 1. At this time, use the limit assembly 3 installed by rotation of the pulley 2 to limit the pulley 2, and then pass the cable from the pulley 2 and the inner wall of the shaft bridge 7 and place it in the middle position. During the installation process, the pulley 2 will move with the cable, and the cable will push the limit assemblies 3 installed by rotation of the pulley 2 at both ends to rotate, and the cable can be laid at this time.

[0035] Thus, through the limitation between the several limiting components 3 and the first installation component 1, the several limiting components 3 are installed on the first installation component 1, and then the cables are passed through the inner wall of the pulley 2 and the shaft bridge 7 and placed in the middle position. During the installation process, the several cables will push the limit components 3 installed at both ends of the pulley 2 to rotate, and the cables can be laid at this time. Furthermore, during the installation process, the position between two adjacent limiting components 3 can be adjusted according to the installation position of the cables. In this way, not only the laying of multiple cables can be guaranteed, but also the installation position of adjacent cables can be adjusted, so as to avoid the problem of overlapping layers when the cables are tied, time-consuming and labor-intensive sorting, and finally the problem of chaotic crossing of cables in the bridge.

[0036] Thus, by adjusting the length between the second mounting component 4 and the first mounting component 1 according to the length of the inner cavity of the shaft bridge 7, the clamping component 6 and the gear bar 5 are manually rotated to engage with each other, and then the self-locking inside the clamping component 6 prevents sliding movement between the clamping component 6 and the gear bar 5, and there is no relative sliding between the first mounting component 1 and the second mounting component 4. Then, by adjusting the length between the second mounting component 4 and the first mounting component 1, different sizes of shaft bridges 7 can be coped with, thereby increasing the practicability of the cable laying device.

[0037] In one embodiment, for the first mounting assembly 1 , the first mounting assembly 1 includes a mounting rod 101 , and a first anti-slip plate 102 is fixedly mounted on one end of the mounting rod 101 .

[0038] The first anti-skid plate 102 is used to ensure that the mounting rod 101 is firmly fixed to the shaft bridge 7 when the mounting rod 101 is installed.

[0039] In one embodiment, for the above-mentioned limiting assembly 3, the limiting assembly 3 includes a fixed plate 301, the fixed plate 301 is rotatably mounted on the pulley 2, a rotating plate 302 is rotatably mounted in the inner cavity of the fixed plate 301, a plurality of fixed blocks 303 are fixedly mounted inside the rotating plate 302, a first sliding rod 304 is slidably mounted inside the plurality of fixed blocks 303, and one end of the first sliding rod 304 is rotatably mounted on the fixed plate 301.

[0040] The other end of the first sliding rod 304 is rotatably mounted with a limiting wheel 305 , and a plurality of the limiting wheels 305 are all attached to the circumferential surface of the mounting rod 101 . The circumferential surface of the rotating plate 302 is rotatably mounted with a first moving block 306 .

[0041] A second moving block 307 is fixedly mounted on one end of the fixing plate 301 , and a threaded rod 308 is threadedly mounted between the first moving block 306 and the second moving block 307 .

[0042] After adjusting the positions of the fixing plate 301 and the pulley 2 according to the installation positions of each cable, the threaded rod 308 is then rotated with a wrench, and the threaded rod 308 will then drive the threaded first moving block 306 and the second moving block 307 to approach each other. Since the second moving block 307 is fixedly installed with the second moving block 307, the first moving block 306 will then drive the rotatable rotating plate 302 to rotate, and then the rotating plate 302 will drive the fixedly installed several fixed blocks 303 to rotate. Since the first sliding rod 304 is slidably installed inside the several fixed blocks 303, the several fixed blocks 303 will then drive the first sliding rod 304 on each of them to rotate on the fixing plate 301, and then the several fixed blocks 303 will move toward the installation rod 101 The two cables are converged on the outer wall until they are completely limited by the installation rod 101, and then the pulley 2 installed on the fixed plate 301 is limited in the horizontal position, and then the cable is passed through the pulley 2 and the inner wall of the shaft bridge 7 and placed in the middle position. During the installation process, the pulley 2 will move with the movement of the cable, and the cable will push the limit components 3 installed at both ends of the pulley 2 to rotate. At this time, the cable can be laid, and then during the installation process, the position between the two adjacent limit components 3 can be adjusted according to the installation position of the cable. This not only ensures the laying of multiple cables, but also adjusts the installation position of adjacent cables, so as to avoid the problem of overlapping layers when the cables are tied, time-consuming and labor-intensive sorting, and finally the problem of chaotic cable crossing in the bridge.

[0043] In one embodiment, for the above-mentioned second mounting component 4, the second mounting component 4 includes a second sliding rod 401, the second sliding rod 401 is slidably installed in the inner cavity of the mounting rod 101, and the other end of the second sliding rod 401 is fixedly installed with a second anti-slip plate 402, and the gear bar 5 is fixedly installed on the second anti-slip plate 402.

[0044] The clamping assembly 6 comprises a mounting frame 601 , and the mounting frame 601 is fixedly mounted on the mounting rod 101 . A clamping rod 602 is rotatably mounted inside the mounting frame 601 .

[0045] A buckle 603 is rotatably mounted on one end of the mounting frame 601 , and a clamping rod 604 is fixedly mounted on one end of the clamping rod 602 . The buckle 603 and the clamping rod 604 are clamped with each other.

[0046] When in use, first, the mounting rod 101 and the second sliding rod 401 are respectively placed on the inner wall of the shaft bridge 7, and then the length between the mounting rod 101 and the second sliding rod 401 is adjusted according to the length of the inner cavity of the shaft bridge 7. During the adjustment process, the second sliding rod 401 will drive the fixedly installed gear bar 5 to move under the clamping rod 602. After the adjustment, the clamping rod 602 is manually rotated to clamp with the gear bar 5, and then the buckle 603 is rotated to clamp with the clamping rod 604 fixedly installed at one end of the clamping rod 602, so as to limit the movement of the mounting rod 101 and the second sliding rod 401, and then the length between the mounting rod 101 and the second sliding rod 401 is adjusted to cope with shaft bridges 7 of different sizes, thereby increasing the practicality of the cable laying device.
