Description

A traction device for laying optical cables Technical Field

[0001] This utility model relates to the technical field of optical cable laying equipment, and in particular to a traction device for optical cable laying. Background Technology

[0002] As an infrastructure of modern communication networks, the quality and efficiency of optical cable laying are crucial. During the laying process, in order to reduce frictional damage to the optical cable and ensure its smooth transmission, traction devices are usually used to guide and pull the cable.

[0003] Existing optical cable pulling devices typically include guide wheels or guide grooves to define the cable's path and prevent it from shifting or twisting during the pulling process. These guiding structures are crucial for ensuring the quality of optical cable laying.

[0004] However, in actual laying projects, a wide variety of optical cables are used, with varying diameters. Traditional traction devices often have fixed-size guide structures, or require cumbersome manual adjustments by operators using tools. When encountering optical cables whose dimensions do not match the guide structure, if the gap is too large, it cannot provide effective guidance, causing the cable to sway; if the gap is too small, it will excessively compress the cable, increasing traction resistance and potentially damaging the fiber core, severely impacting communication quality. This inconvenience in adjustment and poor adaptability significantly reduces the efficiency and reliability of laying work.

[0005] Therefore, this utility model proposes a traction device for laying optical cables to overcome the shortcomings of the prior art. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a traction device for optical cable laying, which aims to improve the problems of inconvenient adjustment of the guiding mechanism, difficulty in quickly and accurately adapting to different specifications of optical cables, and complex and laborious internal maintenance and operation of the existing optical cable laying traction device.

The second electric push rod is mounted on the support plate, and its output end is fixedly connected to the push block. The second controller is electrically connected to the second electric push rod to achieve automated control of the opening and closing of the cover plate.

[0010] Preferably, the optical cable laying traction device further includes a traction belt, which is disposed on the support plate and located below the guide wheel of the adjusting assembly, for supporting and transporting the optical cable.

[0011] Preferably, in the flipping assembly, the support block is fixedly connected to the side wall of the support plate, providing a stable fulcrum for the flipping action.

[0027] 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.

[0028] Referring to Figures 1-5, this utility model embodiment provides a traction device for optical cable laying. This device aims to solve the structural defects of existing optical cable laying devices, such as the difficulty in quickly and accurately adapting to optical cables of different specifications and the inconvenience of internal maintenance and operation.

[0029] Specifically, it includes a support plate 1 that serves as the mounting base for the entire device, and an adjustment assembly 2 and a flipping assembly 3 are also integrated on the support plate 1.

[0030] To achieve precise guidance and adaptive adjustment of the optical cable, the adjustment assembly 2 includes a support frame 203, a second slider 205, a first slider 204, a limiting block 206, a limiting groove 207, a guide wheel 208, a first electric push rod 202, and a first controller 201. In the specific assembly relationship, the support frame 203 is fixedly connected to the upper surface of the support plate 1 by welding or bolting, providing a stable installation foundation for the adjustment assembly 2. The second slider 205 is slidably connected to the support frame 203 through a dovetail groove or linear guide rail structure, allowing the second slider 205 to reciprocate along the length of the support frame 203. A limiting groove 207 is provided on the body of the second slider 205 as a motion constraint. The first slider 204 is also slidably connected to the upper surface of the second slider 205 through a sliding fit. The body of the limiting block 206 is firmly fixedly connected to the first... The slider 204 and the free end of the limiting block 206 are slidably disposed in the limiting groove 207 inside the second slider 205, so that the movement of the first slider 204 can be converted into the compound movement of the second slider 205 through the cooperation of the limiting block 206 and the limiting groove 207; the guide wheel 208 is rotatably mounted on the bracket fixedly connected to the side of the second slider 205 through a rotating shaft, so the position of the guide wheel 208 changes with the movement of the second slider 205; the housing of the first electric push rod 202 is mounted on the support plate 1, and the telescopic output end of the first electric push rod 202 is fixedly connected to the side of the first slider 204 to provide driving force for the movement of the first slider 204; the first controller 201 is electrically connected to the first electric push rod 202 through a wire, and the housing of the first controller 201 is fixed to the outer side wall of the support plate 1 for receiving commands and controlling the action of the first electric push rod 202.

[0031] The flipping assembly 3 includes a cover plate 5, a support block 308, a rotating shaft 307, a rotating block 306, a sliding groove 305, a push block 303, a sliding column 304, a second electric push rod 302, and a second controller 301. The cover plate 5 is a rectangular plate that covers the support plate 1 in the closed state, forming the top shell of the device. The support block 308 is a thick metal block, fixed to the side wall of the support plate 1 by welding or high-strength bolts, providing a solid support point for the flipping mechanism. The rotating block 306 is an irregularly shaped structural component with a through hole at its lower part, through which it is rotatably connected to the rotating shaft 307. Both ends of the rotating shaft 307 are fixed to the support block 308. The upper surface of the rotating block 306 is fixedly connected to the lower surface of the cover plate 5 by bolts or welding, thus integrating the cover plate 5 with the rotating mechanism. Inside the rotating block 306, a sliding groove 305 is provided as a motion conversion track. The push block... 303 is a slider that can slide horizontally. On the upper surface of the push block 303, a vertically extending sliding column 304 is fixedly connected. The top end of the sliding column 304 is slidably disposed inside the sliding groove 305 of the rotating block 306. The head of the sliding column 304 can preferably be set as a rolling roller to reduce sliding friction. The housing of the second electric push rod 302 is mounted on the support plate 1, and the telescopic output end of the second electric push rod 302 is fixedly connected to the rear end face of the push block 303, providing a power source for the horizontal reciprocating motion of the push block 303. The second controller 301 is electrically connected to the second electric push rod 302 through a wire and is used to control the start, stop and telescopic direction of the second electric push rod 302, thereby controlling the opening and closing of the cover plate 5. The housing of the second controller 301 is fixed to the outer wall of the support plate 1 and is arranged side by side with the first controller 201 of the adjustment assembly 2 to form a centralized control panel, which makes it convenient for the operator to complete all electric adjustment functions in the same position.

[0032] It also includes a traction belt 4, which is located in the internal space above the support plate 1 and is positioned vertically below the guide wheel 208 of the adjustment component 2. During the laying process, the optical cable is placed on the upper surface of the traction belt 4. The traction belt 4 provides support and active or passive transmission force for the optical cable. The traction belt 4 itself can be a ring-shaped synchronous belt or conveyor belt made of high friction coefficient rubber material. It is arranged around the transmission system composed of the driving wheel and the driven wheel to ensure the smooth transmission of the optical cable.

[0033] The support block 308 in the flip assembly 3 is firmly fixed to the side wall of the support plate 1. This layout makes the axis of the rotating shaft 307 parallel to the side of the support plate 1. When the cover plate 5 is flipped, the cover plate 5 will open to one side of the device, thereby completely exposing the entire internal space of the device, which provides convenience for subsequent maintenance and repair work.

[0034] The sliding column 304 in the flipping assembly 3 extends vertically upward from the upper end face of the push block 303. This vertical arrangement allows the sliding column 304 to reliably slide in the sliding groove 305 of the rotating block 306 located above it when the second electric push rod 302 pushes the push block 303 to move horizontally. The structure is simple and the force transmission is direct and effective.

[0035] The sliding groove 305 in the flipping assembly 3 is designed as a groove extending radially or arc-shaped along the rotating block 306. If the sliding groove 305 is a radial straight groove, the displacement of the push block 303 is approximately linearly related to the flipping angle of the cover plate 5, making control simple.

[0036] The axis of the rotating shaft 307 in the flipping assembly 3 is set horizontally, and the flipping action of the cover plate 5 is carried out around a horizontal axis, just like the opening method of the box lid. This setting conforms to conventional operating habits, and the structural center of gravity changes stably, which is beneficial to the stability of the entire device.

[0037] Working principle: When the device is working, the optical cable is first placed on the traction belt 4, and then the distance between the upper and lower traction belts 4 is adjusted according to the size of the optical cable. After adjustment, the guide wheel 208 is adjusted by the adjustment component 2 to make the optical cable pass smoothly out of the device according to the size of the optical cable. After the optical cable is laid, the cover plate 5 is flipped out of the device by the flipping component 3 on the support plate 1 to perform internal maintenance on the device.

[0038] After the optical cable is placed into the device, the first controller 201 fixed on the support plate 1 is activated. The first controller 201 acts on the first electric push rod 202 to push the first slider 204 fixed on the first electric push rod 202, so that the first slider 204 slides on the second slider 205 which is slidably connected to the first slider 204. When the first slider 204 slides, the limiting block 206 fixed on the first slider 204 slides with the first slider 204 in the limiting groove 207 on the second slider 205. Since the limiting groove 207 is fixed in the second slider 205, when the limiting block 206 slides in the limiting groove 207, it will drive the second slider 205 to slide on the support frame 203 which is slidably connected to the second slider 205 and adjust the guide wheel 208 fixed on the second slider 205 according to the size of the optical cable. After the adjustment is completed, the operation of the first controller 201 is stopped and the optical cable is pulled to smoothly pass the optical cable out of the device.

[0039] After the device finishes pulling the optical cable, the second controller 301 fixed on the support plate 1 is activated. After the second controller 301 is activated, it acts on the second electric push rod 302, causing the second electric push rod 302 to push the push block 303 fixed on the second electric push rod 302. As the push block 303 is pushed, the sliding column 304 fixed on the push block 303 will slide in the sliding groove 305 that is slidably connected to the sliding column 304. Since the sliding groove 305 is fixed in the rotating block 306, when the sliding column 304 slides in the sliding groove 305, it will drive the rotating block 306 to rotate on the rotating shaft 307 that is rotatably connected to the rotating block 306 and fixed to the support block 308, thus flipping the cover plate 5. After the cover plate 5 is flipped out of the device, the operation of the second controller 301 is stopped and the internal parts of the device are maintained. After the maintenance is completed, the second controller 301 is activated to return the cover plate 5 to its original position.
