Description

Technical Field

[0001] This utility model belongs to the field of cable laying construction technology, and relates to an auxiliary device, particularly a cable laying device at the bend of a cable tray. Background Technology

[0002] The conventional cable laying process in cable trays involves manually pulling the cables or using a winch. This is relatively easy to do in straight sections, but when the cable trays turn, the weight and rigidity of the cables require the cable laying personnel to apply external force to guide them so that the cables can be laid in the intended direction.

[0003] In actual on-site construction, cable trays are generally installed above other electromechanical pipelines at a relatively high height. According to the general rules of electromechanical engineering construction, when the cables arrive on site for laying, other electromechanical pipelines have already been basically installed. Working at height with limited operating space, especially at the bends or branches of the cable trays, makes it difficult for construction personnel to guide the operation manually, resulting in low construction efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable laying device at cable tray bends, which can provide cable guidance at cable tray bends or branches, avoiding manual guidance in these areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable laying device at a bend in a cable tray includes a support mechanism, a fixing mechanism, and a roller mechanism. The support mechanism is composed of several support members that are rotatably connected in sequence. The number of support members is equal to and corresponds one-to-one with the number of cable tray sections at the bend. The support members are fixed to the inner wall of the corresponding cable tray section by the fixing mechanism. The "inner" in "inner wall of cable tray section" refers to the inner side of the bend. The roller mechanism includes several horizontal rollers arranged in the horizontal direction and several vertical rollers arranged in the vertical direction. Both the horizontal and vertical rollers are located inside the support members. The "inner" in "inner" in "inner" refers to the inner side viewed from the overall cable tray. The horizontal and vertical rollers are rotatable relative to the support members.

[0007] To optimize the above technical solution, the specific measures also include:

[0008] Furthermore, the fixing mechanism includes several clamping components; the number of clamping components is equal to the number of support members and corresponds one-to-one, and each support member is clamped and fixed to the cable tray section by the corresponding clamping component.

[0009] Furthermore, the clamping assembly includes a clamping seat and a clamping screw; the clamping seat is inverted U-shaped and fits around the inner sidewall of the support member and the cable tray section; the clamping screw passes through the outer sidewall of the clamping seat and is threadedly connected to it; by rotating the clamping screw, the clamping screw moves into the clamping seat until it abuts against the cable tray section, and the support member and the cable tray section are clamped and fixed.

[0010] Furthermore, a clamping plate is fixed to the inner end of the clamping screw.

[0011] Furthermore, the outer wall of the clamping seat has a screw hole through which the clamping screw passes, and a clamping nut matching the clamping screw is fixed on the outer and / or inner side of the screw hole, and the clamping screw is threadedly connected to the clamping seat through the clamping nut; a trapezoidal wing nut is fixed on the outer end of the clamping screw.

[0012] Furthermore, the support member is a channel steel; the three channel steels are chamfered at 45°, the two ends of the middle channel steel are chamfered, and one end of the other channel steel is chamfered; the support members are connected by hinges.

[0013] Furthermore, both the horizontal and vertical rollers include a roller threaded rod, a roller, two roller washers, and two roller nuts; the roller is fitted onto the roller threaded rod and can rotate around the roller threaded rod as an axis under the action of external force; the roller washers are annular and fitted onto the roller threaded rod; the two roller washers are located at both ends of the roller; the two roller nuts are threadedly connected to both ends of the roller threaded rod and located outside the roller washers; the roller nuts limit the roller between the two roller washers.

[0014] Furthermore, the support member has mounting holes; the end of the threaded rod of the horizontal roller passes through the mounting holes and is fixed to the support member by a matching mounting nut; the vertical roller is equipped with a roller support; the roller support is fixed to the inner wall of the support member, and the lower end of the threaded rod of the vertical roller is fixed inside the roller support.

[0015] Furthermore, each of the supports is equipped with at least one horizontal roller and / or at least one vertical roller.

[0016] Furthermore, the number of support members is three; the middle support member is equipped with two horizontal rollers; the two side support members are equipped with one horizontal roller and two vertical rollers, with the two vertical rollers located on both sides of the horizontal roller.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a cable laying device at the bend of a cable tray, which consists of a support mechanism, a fixing mechanism, and a roller mechanism. The support mechanism is used to install the roller mechanism and can adjust the angle according to the cable tray's direction to ensure a proper fit. The roller mechanism consists of several horizontal and vertical rollers. The vertical rollers guide the cable horizontally, while the horizontal rollers bear the cable's own weight. Both types of rollers can adapt to the cable's sliding trajectory in all directions, allowing the cable to slide more smoothly through the bend under the rotation of the rollers. The fixing mechanism secures the entire device to the side wall of the cable tray, preventing displacement during cable dragging. This is achieved by tightening the clamping screws, making operation convenient. This utility model device is simple to manufacture, easy to disassemble and assemble, reusable, and has few installation restrictions. It can be directly installed and fixed inside the cable tray, avoiding manual guidance of the cable at bends, reducing labor input, and improving production efficiency. Attached Figure Description

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, this utility model provides a cable laying device at the bend of a cable tray, including a support mechanism 1, a fixing mechanism 2, and a roller mechanism 3.

[0026] The support mechanism 1 is composed of several support members 11 that are rotatably connected in sequence. For example... Figure 6As shown, the number of support members 11 is equal to and corresponds one-to-one with the number of cable tray sections A1 at the bends of cable tray A. The support members 11 are fixed to the inner wall of the corresponding cable tray section A1 by the fixing mechanism 2. "Inner" in the inner wall of cable tray section A1 refers to the inner side of the bend. Since the support members 11 are rotatably connected, the angle of the support mechanism 1 can be adjusted according to on-site construction needs. The roller mechanism 3 includes several horizontal rollers 31 arranged horizontally and several vertical rollers 32 arranged vertically. Both the horizontal rollers 31 and the vertical rollers 32 are located inside the support members 11. "Inner" in the inner side of the support member 11 refers to the inner side viewed from the overall cable tray A. The horizontal rollers 31 and the vertical rollers 32 can rotate relative to the support members 11.

[0027] like Figure 1 and Figure 2 As shown, in a specific embodiment, the fixing mechanism 2 includes a plurality of clamping components 21. The number of clamping components 21 is equal to the number of support members 11 and corresponds one-to-one. Each support member 11 is clamped and fixed to the cable tray section A1 by the corresponding clamping component 21.

[0028] The clamping assembly 21 includes a clamping seat 211 and a clamping screw 212. The clamping seat 211 is inverted U-shaped and fits around the inner sidewall of the support member 11 and the cable tray section A1. The clamping screw 212 passes through the outer sidewall of the clamping seat 211 and is threadedly connected to it. By rotating the clamping screw 212, it moves inward into the clamping seat 211 until it abuts against the cable tray section A1, thus clamping and fixing the support member 11 and the cable tray section A1. Specifically, the outer sidewall of the clamping seat 211 has a screw hole through which the clamping screw 212 passes. A clamping nut 213 matching the clamping screw 212 is fixed to the outer side of the screw hole, and the clamping screw 212 is threadedly connected to the clamping seat 211 through the clamping nut 213. The clamping nut 213 can also be fixed to the inner side of the screw hole, or the clamping nut can be fixed to both the inner and outer sides of the screw hole.

[0029] In a preferred embodiment, a clamping plate 214 is fixed to the inner end of the clamping screw 212. The clamping plate 214 enables more stable clamping.

[0030] A trapezoidal wing nut 215 is fixed to the outer end of the clamping screw 212 to facilitate the rotation of the clamping screw 212.

[0031] like Figure 1 and Figure 3 As shown, in a specific embodiment, the support member 11 is a channel steel. Three channel steels are chamfered at 45°, with the middle channel steel having chamfered at both ends and the remaining channel steel having chamfered at one end. The support members 11 are connected by hinges 12. The connection between the channel steel and the hinges 12 is a bolt connection, or it can be a riveted, welded, or other connection method.

[0032] like Figure 1, Figure 4 and Figure 5 As shown, in a specific embodiment, both the horizontal roller 31 and the vertical roller 32 include a roller threaded rod 301, a roller 302, two roller washers 303, and two roller nuts 304. The roller 302 is fitted onto the roller threaded rod 301 and can rotate about the roller threaded rod 301 as an axis under external force. The roller washers 303 are annular and fitted onto the roller threaded rod 301. The two roller washers 303 are located at both ends of the roller 302. The two roller nuts 304 are threaded to both ends of the roller threaded rod 301 and located outside the roller washers 303. The roller nuts 304 limit the roller 302 between the two roller washers 303. That is, the roller 302 is limited by the roller nuts 304 and the roller washers 303. The size of the roller washers 303 is equal to or slightly smaller than the size of the roller 302, but must be larger than the size of the roller nuts 304.

[0033] like Figure 3 As shown, the support member 11 has a mounting hole 311. The end of the threaded rod 301 of the horizontal roller 31 passes through the mounting hole 311 and is fixed to the support member 11 by a matching mounting nut 312. That is, after the end of the threaded rod 301 passes through the mounting hole 311, the mounting nut 312 is screwed on. By tightening the mounting nuts 312 and the roller nut 304 on both sides of the mounting hole 311, the horizontal roller 31 is fixed to the support member 11. Different mounting holes 311 can be selected according to site requirements, thereby changing the installation position of the horizontal roller 31.

[0034] The vertical roller 32 is equipped with a roller support 321. The roller support 321 is fixed on the inner wall of the support member 11, and the lower end of the roller thread rod 301 of the vertical roller 32 is fixed inside the roller support 321.

[0035] Each support 11 is equipped with at least one horizontal roller 31 and / or at least one vertical roller 32.

[0036] like Figure 1 As shown, in this embodiment, there are three support members 11. The middle support member 11 is equipped with two horizontal rollers 31. The two side support members 11 are equipped with one horizontal roller 31 and two vertical rollers 32, with the two vertical rollers 32 located on both sides of the horizontal roller 31.

[0037] In use, first install all horizontal rollers 31 and vertical rollers 32 onto the support mechanism 1. Then, place the device directly on the inside of the bend in the cable tray A. Adjust the angle of the support mechanism 1 as needed so that each support member 11 rests against the inner wall of the corresponding cable tray section A1. Finally, rotate the clamping screws 212 of each clamping assembly 21 until the clamping plate 214 abuts against the outer wall of the cable tray section A1, completing the fixation of the entire device to the cable tray A. When laying cables in this state, the cables will pass through the outside of the vertical rollers 32 and the top of the horizontal rollers 31. That is, the vertical rollers 32 and the horizontal rollers 31 respectively bear the turning force and the weight of the cables, making laying easier and eliminating the need for cable laying personnel to apply external force for guidance.
