Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, and in particular to a cable pulling and threading auxiliary device that can turn at multiple angles. Background Technology

[0002] With social development and the rapid pace of urbanization in China, some of the overhead power lines commonly seen in rural areas and suburbs have been converted to buried cables. This not only saves space but also benefits the aesthetics of the city. However, laying cables underground cannot be done by simply burying them directly. Cable wells and cable ducts must be used for cable laying. When laying cables in cable ducts, the ducts are often very long, sometimes reaching hundreds of meters. Since the cables themselves are flexible and difficult to pass through cable ducts that are tens or hundreds of meters long, a cable puller is needed to pull the cable through the duct and then pull a tension rope or steel wire rope to pull the cable through the cable duct.

[0003] The cable puller is supported on the inner wall of the pipe by an auxiliary device with rollers. The rollers rotate to drive the auxiliary device to move in a straight line inside the pipe. However, the auxiliary device cannot pass smoothly through bends in the pipe, which affects the cable pulling efficiency. Utility Model Content

[0004] In view of the above problems, this utility model provides a cable pulling and threading auxiliary device that can turn at multiple angles.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable pulling and threading auxiliary device with multi-angle steering is provided, including a moving bracket, which includes a guide frame and a connecting frame. The guide frame and the connecting frame are hinged to each other. A driving component is provided at the bottom of both the guide frame and the connecting frame. An installation component for connecting and fixing cables is provided on the connecting frame. A steering component for driving the guide frame to turn is provided on the guide frame.

[0007] Furthermore, the drive assembly includes drive wheels and tracks. At least one set of drive wheels is provided at the bottom of both the guide frame and the connecting frame. The tracks are wound around the drive wheels, and a first drive motor for driving the drive wheels to rotate is provided on the moving support.

[0008] Furthermore, the mounting components include clamps, multiple clamps are fixedly arranged at intervals on the connecting frame, and the size of the clamps gradually increases in the direction away from the guide frame.

[0009] Furthermore, the connecting frame has multiple through holes, a connecting block is fixedly installed on the clamp, and a connecting screw is fixedly installed at the bottom of the connecting block. The connecting screw passes through the through holes and is threadedly connected to the nut.

[0010] Furthermore, the steering assembly includes a movable arm, one end of which is hinged to the guide frame and the other end of which is rotatably mounted with a steering wheel. Two sets of steering assemblies are symmetrically arranged on both sides of the guide frame. A second drive motor for driving the steering wheel to rotate is provided on the movable arm, and a first spring for driving the movable end of the movable arm to rotate away from the guide frame is provided on the guide frame.

[0011] Furthermore, an angle sensor is installed at the rotation axis of the movable arm, and the angle sensor is electrically connected to the second drive motor.

[0013] Furthermore, ball bearings are rolled on both sides of the connecting frame and the guide frame.

[0014] The beneficial effects of this utility model are as follows: When pulling cables through pipes, the cables are fixed to suitable clamps according to their dimensions.

Detailed Implementation

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] This application discloses a cable pulling and threading auxiliary device capable of multi-angle steering, referring to... Figure 1The system includes a moving support, which comprises a guide frame 1 and a connecting frame 2. The guide frame 1 and the connecting frame 2 are hinged together. Both the guide frame 1 and the connecting frame 2 have drive components at their bottoms. The connecting frame 2 has mounting components for connecting and fixing cables, and the guide frame 1 has a steering component for turning the guide frame 1. After the cable is mounted on the connecting frame 2 via the mounting components, the drive components drive the guide frame 1 and the connecting frame 2 to move, causing the entire moving support to advance within the pipe. At bends within the pipe, the steering component on the guide frame 1 drives the guide frame 1 to rotate, pulling the connecting frame 2 behind it to turn accordingly.

[0019] Specifically, the drive assembly can be a drive wheel 31 and a track 32. At least one set of drive wheels 31 is rotatably mounted on the bottom of both the guide frame 1 and the connecting frame 2. The track 32 is wound around the drive wheel 31. The first drive motor 33 is fixedly mounted on the moving bracket by bolts. The first drive motor 33 is connected to the drive wheel 31 by transmission via a toothed belt or chain.

[0020] In this embodiment, the installation component package can be a clamp 6. Multiple clamps 6 are spaced apart on the connecting frame 2. The size of the clamps 6 gradually increases in the direction away from the guide frame 1. Cables can be passed through clamps 6 of different sizes according to the cable size. The clamp 6 has a movable opening. The two ends of the movable opening of the clamp 6 can be connected close together by bolts so that the clamp 6 clamps and fixes the cable.

[0021] Furthermore, the clamp 6 and the connecting frame 2 can be detachably connected. Specifically, a through hole 7 is vertically opened on the connecting frame 2, and a connecting block is fixedly connected to the bottom of the clamp 6. At least two connecting screws 71 are fixedly connected to the bottom of the connecting block. The connecting screws 71 pass through the through hole 7 and are threadedly connected to the nut. Multiple through holes 7 are opened on the connecting frame 2, so that the clamp 6 can be connected to different positions on the connecting frame 2. For small-sized cables, multiple clamps 6 can be installed side by side on the connecting frame 2, so that the device can drag multiple cables forward at one time. Special installation components can also be selected according to the cable type.

[0022] In this embodiment, the steering assembly includes a movable arm 41. One end of the movable arm 41 is hinged to the guide frame 1, and the other end is rotatably mounted with a steering wheel 42. Two sets of steering assemblies are symmetrically arranged on both sides of the guide frame 1. A second drive motor 43 is provided on the movable arm 41 to drive the steering wheel 42 to rotate. A first spring 44 is provided on the guide frame 1 to drive the movable end of the movable arm 41 to rotate away from the guide frame 1. The first spring 44 provides the movable arm 41 with flexible rotational margin. When the guide frame 1 moves to the pipe bend, the steering wheel 42 contacts the inner wall of the pipe and pushes the movable arm 41 to squeeze the first spring 44, so that the guide frame 1 can smoothly pass through the pipe bend. When the auxiliary device moves out of the pipe bend, the movable arm 41 returns to its original position under the elastic force of the first spring 44, pushing the guide frame 1 to move forward along the centerline of the pipe.

[0023] To further enable the guide frame 1 to quickly and smoothly navigate pipe bends, an angle sensor 45 is installed at the rotation shaft of the movable arm 41. The angle sensor 45 can be a grating sensor. A controller is installed on the guide frame 1, and the angle sensor 45 is electrically connected to the second drive motor 43 through the controller. When the angle sensor 45 detects that the rotation angle of the movable arm 41 exceeds a preset angle threshold, the controller controls the second drive motor 43 to rotate, so that the rotating wheel actively rotates to guide the rotation of the guide frame 1 until the angle sensor 45 detects that the movable arm 41 has rotated and resets, and controls the second drive motor 43 to stop rotating. The second drive motor 43 can be a motor. After the second drive motor 43 stops operating, the rotating wheel can continue to rotate.

[0024] In other feasible embodiments, the steering assembly may also adopt a telescopic arm with a length extension function. The steering wheel 42 is rotatably connected to the end of the telescopic arm that extends out of the guide frame 1. A spring is set in the telescopic arm to drive the extension and retraction until the arm is extended to its maximum length. By setting a pressure sensor or a contact sensor on the telescopic arm, the second drive motor 43 can be activated to actively drive the steering wheel 42 to rotate after the telescopic arm is compressed by a certain amount.

[0025] Furthermore, a connecting plate 51 is provided at one end of the guide frame 1 near the connecting frame 2, and a guide sleeve 52 is vertically fixed on the connecting plate 51. A guide post 53 is vertically fixed at one end of the connecting frame 2 near the guide frame 1. The inner diameter of the guide sleeve 52 is larger than the diameter of the guide post 53, and a second spring 54 is sleeved on the guide post 53. The second spring 54 is used to drive the guide sleeve 52 to move downward. When the moving support travels through the protrusions on the inner wall of the pipe, the guide frame 1 can float up and down and rotate relative to the connecting frame 2, so that the moving device can travel smoothly in the pipe.

[0026] Furthermore, rolling balls 8 are rolled on the side walls of both sides of the connecting frame 2 and the guide frame 1. When the device turns in the pipeline, the connecting frame 2 and the guide frame 1 contact the inner wall of the pipeline at the bend. The rolling balls 8 can make the connecting frame 2 and the guide frame 1 roll in contact with the inner wall of the pipeline, which can avoid the corner of the connecting frame 2 and the guide frame 1 rubbing against the inner wall of the pipeline, and ensure that the device passes smoothly in the pipeline.
