Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically a cable laying traction device for cable laying. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, such as overhead, underground (pipes and direct burial), underwater, wall, and tunnel. During the cable laying process, the cable is in a wound state before laying. In order to facilitate the movement of the cable to the designated location, a traction device is often used to pull the cable.

[0003] For example, patent CN219906466U discloses a cable laying traction device that can improve the friction and stability during traction by adjusting the clamping force of the belt on the cable, and prevent slippage due to humid environments during traction. However, in practical applications, the cable cannot be adjusted according to the application environment, such as the laying traction between overhead and ground surfaces. Especially when workers carry the outer end of the cable to lay it in the air, the inability of the above-mentioned device to adjust the angle when pulling the cable at a height will cause the cable to be in a horizontal state, affecting the resistance of the workers pulling the cable. Therefore, we provide a cable laying traction device for cable laying to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a cable laying traction device for cable laying. This device can not only adjust the angle according to the application of overhead or ground, but also adjust the clamping of cables of different diameters, improve the friction of the traction component on the cable surface, and prevent slippage during traction due to external moisture or other factors.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cable laying traction device for cable laying is provided, including a rectangular and horizontally arranged main board, a moving component is provided at the bottom of the main board, and a winding component and a traction mechanism for pulling the cable are provided at the top of the main board.

[0006] The traction mechanism includes two hinged posts and two limiting curved posts fixed to the upper surface of the main board, and a traction plate hinged to the two hinged posts and in contact with the limiting curved posts. The traction mechanism also includes a traction component and an angle adjustment component connected to the traction plate, and a distance adjustment component connected to the traction component.

[0007] Furthermore, the moving component includes two push rods symmetrically fixed to one side of the upper surface of the motherboard, and a crossbar fixedly connected between the two push rods. Universal wheels are installed at all four corners of the bottom surface of the motherboard. By setting up the moving component, the entire device can be easily moved to a predetermined position. It can also be moved by installing a drive device to move the entire device itself, or by manually pushing the crossbar to move the entire device to a predetermined position.

[0008] Furthermore, the winding assembly includes two fixing plates fixed to the upper surface of the main board, and a rotatable mounting roller installed between the two fixing plates. By providing the winding assembly, it is easy to install the cable reel onto the fixing plates, facilitating subsequent cable pulling operations.

[0009] Furthermore, the traction assembly includes two traction rings symmetrically fixed on both sides of the outer surface of the traction plate, and two sets of transmission wheels rotatably connected to the upper surface of the traction plate. Each set of transmission wheels is connected to a traction belt, and the outer surface of the traction belt is provided with anti-slip texture. By setting up the traction assembly and the transmission wheels inside the traction assembly, it is easy to drive the traction belt for transmission, and the anti-slip texture on the surface of the traction belt can be added to facilitate stable contact with the cable surface, making it easier to stabilize and reduce slippage when pulling the cable.

[0010] Furthermore, the traction assembly also includes two grooves formed on the upper surface of the traction plate, and slide rods fixedly connected to the bottom surface of the transmission wheel and slidably engaged with the grooves. A connecting plate is rotatably connected to the lower end of each set of slide rods. By setting the traction assembly and the grooves within it, the distance between the two traction belts can be easily adjusted through the cooperation of the distance adjustment components, ensuring stable contact between the traction belts and the cable surface.

[0011] Furthermore, servo motors are mounted on the bottom surfaces of both connecting plates, and the output ends of the servo motors rotate through the connecting plates and are fixedly connected to the lower end of one of the sliding rods. By setting servo motors, it is easy to drive the transmission wheel to rotate, so that the transmission wheel drives the traction belt to transmit power, thereby enabling the cable to be pulled.

[0012] Furthermore, the distance adjustment assembly includes a dual-output shaft motor mounted on the bottom surface of the traction plate. Both output shafts of the dual-output shaft motor are coaxially and fixedly connected to lead screws. The distance adjustment assembly also includes a lead screw seat fixed to the bottom surface of the connecting plate and threadedly connected to the lead screws. By providing the distance adjustment assembly, the distance between the two sets of traction belts can be easily adjusted, thereby allowing for adjustable clamping according to the cable diameter, ensuring stable contact between the traction belt and the cable, and increasing the friction force during cable traction.

[0013] Furthermore, the angle adjustment assembly includes an electric push rod hinged to the upper surface of the main board, and the output end of the electric push rod is hinged to the bottom surface of the traction ring located on one side of the limiting curved column. The angle adjustment assembly also includes a guide groove formed on the outer surface of the limiting curved column, and a guide rod fixed to the outer surface of the traction plate and slidingly engaged with the inner wall of the guide groove. By setting the angle adjustment assembly, the tilt angle of the traction plate can be easily adjusted, thereby enabling the cable to be laid at an inclined angle during cable pulling. This improves the ability to tilt and pull the cable when it needs to be pulled at a height, reducing the effort required for workers to carry the outer end of the cable at height.

[0014] In actual use, before laying the cable, the universal wheels, push rods and crossbars in the movable assembly make it easy to move the whole device. The cable reel is installed at the mounting roller in the winding assembly, and then the whole device is moved to the predetermined position for subsequent laying work. During cable laying, the outer end of the cable is first passed through two traction rings in sequence. Then, by activating a dual-output shaft motor, the two output shafts drive two lead screws to rotate. Because the threads of the two lead screws are in opposite directions, the lead screws bring the two lead seats closer together, which in turn bring the two lead seats closer together. The connecting plates then move the sliding rod under the limiting action of the sliding groove, causing the transmission wheel and traction belt to clamp the cable. At this point, depending on the application, an electric push rod can be activated. The output end of the electric push rod pushes the traction plate to move, causing the traction plate to tilt at an angle under the limiting action of the guide rod, guide groove, and hinge column, facilitating cable traction and routing during subsequent overhead laying. By activating a servo motor, the output end of the servo motor drives the sliding rod on the same side to rotate, causing the sliding rod to rotate the transmission wheel. The transmission wheel then drives the traction belt to pull the cable outwards, allowing the cable to be discharged. During discharge, workers can carry the outer end of the cable for operation at heights, reducing the effort required for manual cable pulling.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a traction mechanism, can easily clamp the cable according to different diameters. After clamping, the cable can be pulled and transmitted through the traction component. At the same time, the horizontal traction and tilt angle of the cable can be adjusted according to the application, so as to facilitate cable laying on the ground or in the air, improve the scope of application and practicality, and reduce the effort required for workers to pull the cable.

[0017] 2. By setting an angle adjustment component, this utility model can easily adjust the tilt angle of the traction plate, so that the cable can be laid at an inclined angle when traction is required. This improves the ability to tilt and pull the cable when it needs to be pulled at a high position. The setting of the traction ring can facilitate the initial limiting and guidance of the cable, so that the traction belt can make stable contact with the cable and improve the stability of traction.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] As described in the background art, during cable laying, the traction cannot be adjusted according to the application, such as overhead or ground laying. Especially when workers carry the outer end of the cable for laying in the air, the inability of the aforementioned device to adjust the angle when pulling the cable at a height results in the cable being in a horizontal state, affecting the resistance of the worker pulling the cable. To address this, this embodiment provides a cable laying traction device for cable laying. This device can not only adjust the angle according to the application of overhead or ground laying, but also adjust the clamping of cables of different diameters, increasing the friction of the traction component on the cable surface, and preventing slippage during traction due to external moisture or other factors.

[0025] See Figures 1 to 4This embodiment proposes a cable laying traction device for cable laying, including a main board 1, a movable component provided on the bottom surface of the main board 1, a winding component provided on the upper surface of the main board 1, and a traction mechanism 7 for pulling the cable.

[0026] refer to Figures 1 to 4 The movable component facilitates the movement of the entire device, and the winding component allows for easy installation of cable reels within it. This enables the movable component to move the entire device to a predetermined position for subsequent laying.

[0027] The moving assembly includes two push rods 3 fixed to the upper surface of the motherboard 1, and a crossbar 4 connected to the push rods 3. Universal wheels 2 are installed at the four corners of the bottom surface of the motherboard 1.

[0028] By setting up a movable component, the entire device can be easily moved to a predetermined position. It can also be moved by installing a drive device to drive the movement of the entire device, or by manually pushing the crossbar 4 to move the entire device to a predetermined position.

[0029] As a supplement, the universal wheel 2 is a device disclosed in the prior art and has a self-locking function, which facilitates the movement and stable parking of the entire device.

[0030] The winding assembly includes two fixing plates 5 fixed to the upper surface of the main board 1, and a rotatable mounting roller 6 installed between the two fixing plates 5. By setting up the winding assembly, it is easy to install the cable reel to the fixing plate 5, so as to facilitate the subsequent cable pulling operation.

[0031] As a supplement, the fixing plate 5 can be installed or removed at the mounting roller 6. The installation or removal method, such as bolts, can be selected according to the needs.

[0032] The traction mechanism 7 includes two hinged posts 701 and two limiting curved posts 702 fixed on the upper surface of the main board 1, and a traction plate 703 hinged to the two hinged posts 701 and in contact with the limiting curved posts 702. The traction mechanism 7 also includes a traction component and an angle adjustment component connected to the traction plate 703, and a distance adjustment component connected to the traction component.

[0033] refer to Figures 1 to 4 The traction mechanism 7 is designed to facilitate cable traction and can be adjusted according to the cable diameter, so that the traction component can stably contact the cable surface, thereby increasing the friction when tractioning the cable and preventing the cable from slipping on the traction component when traction is performed in humid environments.

[0034] As a supplement, the angle adjustment component allows for easy adjustment of the angle during cable laying and traction as needed, enabling horizontal and inclined cable traction to suit both overhead and ground-level cable laying.

[0035] The traction assembly includes two traction rings 704 fixed on the outer surface of the traction plate 703, and two sets of transmission wheels 705 rotatably connected to the upper surface of the traction plate 703. A traction belt 706 is connected between the two sets of transmission wheels 705.

[0036] By setting up a traction assembly, the transmission wheel 705 inside the traction assembly can easily drive the traction belt 706 for transmission. Furthermore, anti-slip textures can be added to the surface of the traction belt 706 to facilitate stable contact with the cable surface, making it easier to stabilize the cable traction and reduce slippage.

[0037] As a supplement, the traction ring 704 facilitates the initial positioning and guidance of the cable, enabling the traction belt 706 to maintain stable contact with the cable and improving traction stability.

[0038] The traction assembly also includes two grooves 707 formed on the upper surface of the traction plate 703, and a slide rod 708 fixedly connected to the bottom surface of the transmission wheel 705 and slidingly engaged with the grooves 707. The lower ends of the two sets of slide rods 708 are rotatably connected to a connecting plate 709.

[0039] By setting up a traction assembly and the slide groove 707 inside the traction assembly, the distance between the two traction belts 706 can be adjusted by the cooperation of the distance adjustment components, so that the traction belts 706 can make stable contact with the cable surface.

[0040] As a supplement, the connection plate 709 facilitates the installation of the drive components and the movement between the two drive wheels 705.

[0041] Servo motors 7010 are mounted on the bottom surfaces of both connecting plates 709, and the output end of the servo motor 7010 rotates through the connecting plate 709 and is fixedly connected to the lower end of the slide bar 708 on one side.

[0042] By setting a servo motor 7010, it is easy to drive the transmission wheel 705 to rotate, so that the transmission wheel 705 drives the traction belt 706 to drive the cable.

[0043] As a supplement, the output end of the servo motor 7010 can rotate through the connecting plate 709 and drive the slide rod 708 to rotate in the start state, so that the slide rod 708 drives the transmission wheel 705 to rotate. The transmission wheel 705 can then pull the cable through the traction belt 706. When the slide rod 708 rotates, it can also be driven by the distance adjustment component, so that the slide rod 708 slides in the slide groove 707.

[0044] The distance adjustment assembly includes a dual-output shaft motor 7011 mounted on the bottom surface of the traction plate 703. Both output shafts of the dual-output shaft motor 7011 are fixedly connected to lead screws 7012. The distance adjustment assembly also includes a lead screw seat 7013 fixed on the bottom surface of the connecting plate 709 and threadedly connected to the lead screws 7012.

[0045] By setting a distance adjustment component, the distance between the two sets of traction belts 706 can be easily adjusted, thereby adjusting the clamping according to the cable diameter, ensuring stable contact between the traction belt 706 and the cable, and increasing the friction force when pulling the cable.

[0046] As a supplement, when the distance adjustment component adjusts the distance between the two sets of traction belts 706, the dual output shaft motor 7011 is started. The two output shafts of the dual output shaft motor 7011 drive the two lead screws 7012 to rotate, so that the lead screws 7012 drive the two lead seats 7013 to move closer to each other. Since the thread directions between the two lead screws 7012 are opposite, the two lead seats 7013 can move closer to each other or further away under the thread engagement of the lead screws 7012.

[0047] The angle adjustment assembly includes an electric push rod 7014 hinged to the upper surface of the main board 1, and the output end of the electric push rod 7014 is hinged to the bottom surface of the traction ring 704 located on one side of the limiting curved column 702. The angle adjustment assembly also includes a guide groove 7015 formed on the outer surface of the limiting curved column 702, and a guide rod 7016 fixed to the outer surface of the traction plate 703 and slidingly engaged with the inner wall of the guide groove 7015.

[0048] By setting an angle adjustment component, the tilt angle of the traction plate 703 can be easily adjusted, so that the cable can be laid at an angle when traction is required. This improves the ability to tilt and pull the cable when it needs to be pulled at a high place, reducing the effort required for workers to carry the outer end of the cable at a high place.

[0049] As a supplement, when adjusting the angle, the output end of the electric push rod 7014 can push the outer traction ring 704 and the traction plate 703 to move. Since the other end of the traction plate 703 is limited by the hinge post 701, the traction plate 703 can be tilted. When the traction plate 703 is tilted, it can be tilted stably by the action of the guide groove 7015 and the guide rod 7016.

[0050] Working principle: Before laying the cable, the universal wheels 2, push rods 3 and crossbars 4 in the moving assembly can be used to move the whole device. The cable reel is installed at the mounting roller 6 in the winding assembly, and then the whole device is moved to the predetermined position for subsequent laying work.

[0051] During cable laying, the outer end of the cable is first passed through two traction rings 704 in sequence. Then, the dual-output shaft motor 7011 is started. The two output shafts of the dual-output shaft motor 7011 drive two lead screws 7012 to rotate. Since the threads of the two lead screws 7012 are in opposite directions, the lead screws 7012 drive two lead seats 7013 to move closer together. This, in turn, causes the two lead seats 7013 to drive two connecting plates 709 to move closer together. The connecting plates 709 then drive the slide rod 708 to move under the limiting action of the slide groove 707, causing the transmission wheel 705 and the traction belt 706 to clamp the cable. At this point, depending on the application, the electric push rod 7014 can be activated. The output end of 7014 pushes the traction plate 703 to move, so that the traction plate 703 is tilted at an angle by the guide rod 7016, the guide groove 7015 and the hinge column 701, so as to facilitate the traction and laying of cables during subsequent overhead laying. By starting the servo motor 7010, the output end of the servo motor 7010 drives the slide bar 708 on the same side to rotate, so that the slide bar 708 drives the transmission wheel 705 to rotate, and the transmission wheel 705 drives the traction belt 706 to pull the cable, so that the cable can be discharged outward. During discharge, the workers can carry the outer end of the cable and operate it when working at height, reducing the effort required when the workers manually pull the cable.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
