Description

Technical Field

[0001] This utility model relates to the field of cable equipment technology, specifically to a retractable guide rail type cable laying system. Background Technology

[0002] Indoor cable trays play an indispensable role as an important auxiliary facility for cable laying. Like carefully designed bridges, they not only provide stable support for cables but also ensure their neat and orderly arrangement, facilitating subsequent maintenance and management. Indoor cable trays are usually made of materials such as metal or high-strength plastics, featuring corrosion resistance, fire resistance, and high load-bearing capacity, meeting the needs of various complex environments. However, when using existing laying devices to lay cables on indoor cable trays, construction workers inevitably face a series of challenges and inconveniences. Among them, the most significant problem is the obstruction of the laying process by connecting rods. Since indoor cable trays need to be tightly connected to walls or other supporting structures through connecting rods to ensure their stability, these connecting rods become insurmountable obstacles during cable laying. When cables pass through connecting rods, they often need to be laid in sections, that is, the laying must be paused at each connecting rod to adjust the cable direction and bypass or cross the connecting rod. This intermittent laying method not only greatly reduces laying efficiency but also increases the risk of cable surface damage. Repeated pulling and friction can easily wear down the outer sheath of the cable, affecting its insulation performance and service life. In addition, frequent high-altitude operations also pose safety hazards to construction workers. During the laying process, construction workers need to constantly climb the cable trays and adjust the position of the cable, which not only tests their physical fitness and professional skills, but also increases the risk of accidents such as falls.

[0003] Chinese patent document CN207782295U discloses a shallow-buried communication cable laying device, including a support plate, a rotating shaft fixing frame mounted on the support plate, and a rotating shaft mounted on the rotating shaft fixing frame; rollers for winding cables are provided on the shaft; a telescopic guide rail is provided at the front end of the support plate, extending to the bottom of the support plate through a through hole; two sets of parallel support frames are provided below the support plate; the support frames are connected to the support plate through at least two pairs of legs; guide wheels are provided at the front and rear ends of the support frames; tracks are provided on the guide wheels; however, the following defects still exist in the implementation process:

[0004] Although the device described in the above literature is a shallow-buried communication cable laying device that can adapt to various construction environments, it cannot operate on indoor cable trays to assist workers in laying cables indoors. Utility Model Content

[0005] The purpose of this invention is to provide a retractable guide rail cable laying system to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A telescopic guide rail type cable laying system includes a connecting frame; a first extension component is slidably connected to the middle of the connecting frame, a second extension component is slidably connected to the inner cavity of the first extension component, an electric push rod is fixedly connected to the middle of the connecting frame, several mounting components are symmetrically fixedly connected to the lower part of the connecting frame, a traction component is symmetrically fixedly connected to the lower part of the connecting frame away from the first extension component, and docking components are fixedly connected to the sides of the first extension component and the second extension component away from the traction component. The docking component includes a housing four, electromagnets are symmetrically fixedly connected to the upper and lower parts of the housing four, a connecting block is slidably connected to the middle of the housing four, guide rods are fixedly connected to the sides of the two electromagnets near the connecting block, the two guide rods are slidably connected to the connecting block, spring twos are wound around the outer surface of the two guide rods, the side of the electromagnet on the same side near the connecting block is fixedly connected to the spring two, the two spring twos are fixedly connected to the connecting block, and a sensing rod is fixedly connected to the middle of the connecting block near the electric push rod.

[0008] A further improvement of the present invention is that the first extension component includes a housing, which is fixedly connected to the connecting frame. The housing is symmetrically provided with a sliding groove, and the bottom wall of the inner cavity of the two sliding grooves is symmetrically provided with a limiting hole. The housing is symmetrically fixedly connected with a slider, and the two sliders are slidably connected to the connecting frame.

[0009] The above technical solution provides a sliding groove to support and limit the second extension component, preventing it from deviating from the track during movement. The slider is slidably connected to the connecting frame, thus supporting and limiting the first extension component through the cooperation of the connecting frame and the slider.

[0010] A further improvement of the present invention is that the second extension component includes a second outer shell, which is located in the inner cavity of the first outer shell. The second outer shell is symmetrically and fixedly connected with a second slider. The inner cavity of the first sliding groove on the same side is slidably connected to the outer surface of the second slider. Both second sliders are symmetrically and fixedly connected with limit components.

[0011] In the above technical solution, the outer shell is symmetrically and fixedly connected with the slider two, so that the outer shell two can be supported and connected by the slider two.

[0012] A further improvement of the present invention is that the limiting component includes a housing three, a locking block is slidably connected to the inner cavity of the housing three, and a spring one is fixedly connected to the locking block and the bottom wall of the inner cavity of the housing three.

[0013] The above technical solution involves a spring fixedly connected to the inner cavity of the outer shell three, which allows the spring force to move the locking block within the inner cavity of the outer shell three. A limiting hole is provided in the inner cavity of the slide groove one, which allows the locking block to limit the position of the outer shell two by cooperating with the limiting hole.

[0014] A further improvement of the present invention is that the mounting assembly includes a main board and a sub-board. A telescopic rod is symmetrically and fixedly connected to the side of the main board near the sub-board. The piston rod of the telescopic rod is fixedly connected to the telescopic rod. A threaded rod is threadedly connected to the middle of the main board. The telescopic rod is rotatably connected to the threaded rod.

[0015] The above technical solution uses a threaded rod that is rotatably connected to the sub-plate, which allows the sub-plate to move when the threaded rod is rotated, thus making the device suitable for cable trays of different sizes.

[0016] A further improvement of the present invention is that the traction assembly includes a roller and a placement rod, the roller is rotatably connected to the placement rod, the placement rod is fixedly connected to the lower part of the connecting frame, the roller is symmetrically rotatably connected to a limit ring, and both limit rings are threadedly connected to a threaded bolt.

[0017] The above technical solution involves a limit ring connected to a roller that rotates symmetrically, and a threaded bolt is threaded onto the limit ring. This allows the roller to be moved, and the limit ring is then fixed in place by the threaded bolt. This design allows the roller to limit and assist the movement of the cable, preventing wear between the cable and the cable tray during cable movement, which could lead to surface cracking of the cable and affect its normal use.

[0018] A further improvement to the technical solution of this utility model is that both slider one and slider two are T-shaped.

[0019] The above technical solution uses a T-shaped slider, which enhances the stability of sliders 1 and 2 during movement.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] 1. This utility model provides a telescopic guide rail type cable laying system. One end of the cable is fixed by several clamps. Then, by operating an electromagnet, magnetic force is generated, which moves a connecting block, thereby moving a sensing rod. The positioning pin hole on the electric push rod engages with the sensing rod, allowing the electric push rod to move a docking component fixedly connected to a second extension component. This docking component then moves the second extension component. After the second extension component reaches a predetermined position, the above steps are repeated. The system utilizes the docking component fixedly connected to the first extension component and the electric push rod... In conjunction with the first extension component, the second extension component moves, which in turn moves the cable. This assists workers in laying cables on the cable tray. During laying, multiple cables can be fixed, allowing for simultaneous laying of multiple cables. This saves time and reduces the impact of connecting rods, avoiding segmented laying. It also reduces the time workers spend working at heights and eliminates the need for workers to constantly climb the cable tray and adjust cable positions, thus improving safety during cable laying.

[0022] 2. This utility model provides a telescopic guide rail type cable laying system. A threaded rod is rotatably connected to a secondary plate, allowing the secondary plate to move as the threaded rod rotates. This makes the device suitable for cable trays of different sizes, improving its practicality. A limit ring is symmetrically connected to a roller, and a threaded bolt is threaded onto the limit ring, allowing the roller to move. The limit ring is then fixed in place by the threaded bolt. This system uses the roller to limit and assist the movement of the cable, preventing wear between the cable and the cable tray during cable movement, which could lead to surface cracking and affect the normal use of the cable, thus improving the quality of cable laying.

[0036] The present invention will be further described in detail below with reference to embodiments:

[0037] Example 1

[0038] like Figure 1-5As shown, this utility model provides a telescopic guide rail type cable laying system, including a connecting frame 1; a first extension component 2 is slidably connected to the middle of the connecting frame 1, a second extension component 3 is slidably connected to the inner cavity of the first extension component 2, an electric push rod 4 is fixedly connected to the middle of the connecting frame 1, several mounting components 6 are symmetrically fixedly connected to the lower part of the connecting frame 1, a traction component 7 is symmetrically fixedly connected to the lower part of the connecting frame 1 away from the first extension component 2, and docking components 5 are fixedly connected to both the side of the first extension component 2 away from the traction component 7 and the side of the second extension component 3 away from the traction component 7. The docking components 5 include an outer... Shell 4 51, with electromagnets 52 symmetrically fixedly connected to the upper and lower parts of shell 4 51, and a connecting block 55 slidably connected to the middle of shell 4 51. Guide rods 53 are fixedly connected to the side of each electromagnet 52 near the connecting block 55. The two guide rods 53 are slidably connected to the connecting block 55. Springs 2 54 are wound around the outer surface of each guide rod 53. The side of the electromagnet 52 on the same side near the connecting block 55 is fixedly connected to springs 2 54. The two springs 2 54 are fixedly connected to the connecting block 55. A sensing rod 56 is fixedly connected to the middle of the connecting block 55 near the electric push rod 4.

[0039] In this embodiment, the length of the device can be extended by the cooperation of the first extension component 2 and the second extension component 3, thereby facilitating the laying of cables. The traction component 7 can guide the cable during laying to prevent friction between the cable and the cable tray, which would cause wear on the cable surface. The traction component 7 can connect the device to the cable tray. The operation of the electromagnet 52 can generate magnetic force, which then drives the connecting block 55 to move. The guide rod 53 can limit the movement trajectory of the connecting block 55. The second spring 54 can push the connecting block 55 to reset after the electromagnet 52 is de-energized. The sensing rod 56 can sense the position of the positioning pin hole of the electric push rod 4, and then cooperate with the positioning pin hole of the electric push rod 4 to drive the second extension component 3 or the first extension component 2 to move when the electric push rod 4 is running.

[0040] Example 2

[0041] like Figure 10 , Figure 11 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the mounting assembly 6 includes a main board 61 and a sub-board 64. A telescopic rod 62 is symmetrically and fixedly connected to the side of the main board 61 near the sub-board 64. The piston rod of the telescopic rod 62 is fixedly connected to the telescopic rod 62. A threaded rod 63 is threadedly connected to the middle of the main board 61. The telescopic rod 62 is rotatably connected to the threaded rod 63. The traction assembly 7 includes a roller 71 and a placement rod 74. The roller 71 is rotatably connected to the placement rod 74. The placement rod 74 is fixedly connected to the lower part of the connecting frame 1. The roller 71 is symmetrically and rotatably connected to a limiting ring 72. Both limiting rings 72 are threadedly connected to a threaded bolt 73.

[0042] In this embodiment, when it is necessary to lay cables inside the cable tray, the device is first placed on the cable tray. Then, by rotating the threaded rod 63, the position of the threaded rod 63 on the main board 61 is changed, causing the sub-plate 64 to move towards the cable tray. Then, through the cooperation of several mounting components 6, the device can be connected to the cable tray. Next, the construction personnel can slide several rollers 71 and the placement rod 74 according to the number of cables to be placed in the cable tray cavity. After determining the number and position of the rollers 71, the construction personnel rotate the threaded bolt 73, which contacts the placement rod 74, and then limits the position of the limiting ring 72, thereby limiting the position of the rollers 71. Then, the construction personnel connect several cables to several clamps located on the lower side of the docking component 5, and then place the cables on the surface of the rollers 71. This reduces the contact between the cables and the cable tray when laying the cables, and prevents the cables from rubbing against the cable tray when pulling the cables, which could cause the surface of the cables to crack.

[0043] Example 3

[0044] like Figure 7 , Figure 8 , Figure 9 As shown, based on Embodiment 2, this utility model provides a technical solution: Preferably, the second extension component 3 includes a second outer shell 31, which is located in the inner cavity of the first outer shell 21. The second outer shell 31 is symmetrically and fixedly connected to a second slider 32. The inner cavity of the first sliding groove 22 on the same side is slidably connected to the outer surface of the second slider 32. Both second sliders 32 are symmetrically and fixedly connected to a limiting component 33. The limiting component 33 includes a third outer shell 331, which is slidably connected to a locking block 332. The locking block 332 and the bottom wall of the inner cavity of the third outer shell 331 are jointly and fixedly connected to a first spring 333. Both the first slider 24 and the second slider 32 are T-shaped.

[0045] In this embodiment, after the cable connection is completed, the construction worker controls the two electromagnets 52 near the second extension component 3 via the controller. Under the influence of magnetic force, the connecting block 55 moves towards the electromagnets 52, causing the spring 54 to retract. This allows the sensing rod 56 to pass through the positioning pin hole of the electric push rod 4. The construction worker then controls the electric push rod 4 via the controller. When the electric push rod 4 moves, it causes the second extension component 3 to move away from the first extension component 2, which in turn causes the connecting block 55 to retract. The dry clamp moves, which in turn drives several cables to move. When the cables move, they drive several rollers 71 to rotate, thereby reducing the friction when the cables move. When the outer casing 2 31 moves, it drives the slider 2 32 to slide in the inner cavity of the slide groove 1 22. When the second extension component 3 moves to the limited position, under the elastic force of the spring 1 333, it drives the spring 1 333 to extend, and then pushes the locking block 332 to move in the inner cavity of the outer casing 3 331. Then, with the cooperation of the locking block 332 and the limiting hole 23, the position of the outer casing 2 31 can be limited.

[0046] Example 4

[0047] like Figure 6 As shown, based on embodiment 3, this utility model provides a technical solution: preferably, the first extension component 2 includes a housing 21, the housing 21 is fixedly connected to the connecting frame 1, the housing 21 is symmetrically provided with sliding grooves 22, the bottom wall of the inner cavity of the two sliding grooves 22 is symmetrically provided with limiting holes 23, the housing 21 is symmetrically fixedly connected with sliders 24, and the two sliders 24 are slidably connected to the connecting frame 1.

[0048] In this embodiment, the construction worker then controls the electromagnet 52 to be de-energized via the controller. Under the elastic force of the second spring 54, the connecting block 55 moves away from the electric push rod 4. Then, the sensing rod 56 separates from the electric push rod 4. Next, the electric push rod 4 is retracted via the controller. After the electric push rod 4 has retracted, the two electromagnets 52 near the first extension component 2 are operated via the controller. The above steps are repeated. Under the push of the electric push rod 4, the first extension component 2 moves towards the second extension component 3. With the cooperation of the limiting hole 23 and the locking block 332, the second extension component 3 moves together with the first extension component 2. Several cables can then move together. When the electric push rod 4 stops extending, the first extension component 2 and the second extension component 3 also stop moving at the same time. Then, the construction worker can remove several cables from the clamp and place them in the inner cavity of the cable tray, thereby completing the cable laying.

[0049] The working principle of this retractable guide rail cable laying system will be explained in detail below.

[0050] like Figure 1-11 As shown, when it is necessary to lay cables in the inner cavity of the cable tray, the device is first placed on the cable tray. Then, by rotating the threaded rod 63, the position of the threaded rod 63 on the main plate 61 is changed, which drives the sub-plate 64 to move towards the cable tray. Then, through the cooperation of several mounting components 6, the device can be connected to the cable tray. Next, the construction personnel can slide several rollers 71 and the placement rod 74 according to the number of cables to be placed in the inner cavity of the cable tray. After determining the number and position of the rollers 71, the construction personnel rotate the threaded bolt 73, which contacts the placement rod 74, and then limits the position of the limiting ring 72, thereby limiting the position of the rollers 71. Then, the construction personnel connect several cables to several clamps located on the lower side of the docking component 5, and then place the cables on the surface of the rollers 71. This reduces the contact between the cables and the cable tray when laying the cables, and prevents the cables from rubbing against the cable tray when pulling the cables, which could cause the surface of the cables to crack.

[0051] After the cable connection is completed, the construction worker then controls the two electromagnets 52 near the second extension assembly 3 via the controller. Under the action of the magnetic force, the connecting block 55 moves towards the electromagnets 52, which in turn causes the spring 54 to retract. This allows the sensing rod 56 to pass through the positioning pin hole of the electric push rod 4. The construction worker then controls the electric push rod 4 via the controller. When the electric push rod 4 moves, it causes the second extension assembly 3 to move away from the first extension assembly 2, which in turn causes several clamps to move. The movement then drives several cables to move. When the cables move, they drive several rollers 71 to rotate, thereby reducing the friction when the cables move. When the second housing 31 moves, it drives the second slider 32 to slide in the inner cavity of the first slide groove 22. When the second extension component 3 moves to the limited position, under the elastic force of the first spring 333, it drives the first spring 333 to extend, and then pushes the locking block 332 to move in the inner cavity of the third housing 331. Then, with the cooperation of the locking block 332 and the limiting hole 23, the position of the second housing 31 can be limited.

[0052] Next, the construction workers control the electromagnet 52 to de-energize via the controller. Then, under the elastic force of the second spring 54, the connecting block 55 will move away from the electric push rod 4. Then, the sensing rod 56 will separate from the electric push rod 4. Then, the electric push rod 4 will retract via the controller. After the electric push rod 4 has retracted, the two electromagnets 52 near the first extension component 2 will move via the controller. Then, the above steps will be repeated. Under the push of the electric push rod 4, the first extension component 2 will move towards the second extension component 3. With the cooperation of the limiting hole 23 and the locking block 332, the second extension component 3 will move together when the first extension component 2 moves. Then, several cables can move together. When the electric push rod 4 stops extending, the first extension component 2 and the second extension component 3 will also stop moving at the same time. Then, the construction workers can remove several cables from the clamps and place the cables in the inner cavity of the cable tray, thus completing the cable laying.

[0053] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
