Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric power construction, specifically, a cable laying is with the device of leading through. BACKGROUND

[0002] The cable leading-through device is a device for leading through cables in a pipeline, a conduit or other narrow space, and is widely used in the fields of building electrical engineering and communication cable laying, and the main function thereof is to improve the efficiency of cable threading, reduce the difficulty and labor intensity of manual operation, and protect the cable and the pipeline from damage.

[0003] For example, a tumbling cable leading-through device disclosed in Chinese Patent Publication No. CN202222186658.9 includes a central column and a top hat, the top hat is integrally installed at the top end of the central column, a fixed collar is detachably assembled on the outside of the central column, four driving components are uniformly distributed around the central column and connected with the fixed collar, the driving components distributed around the central column realize frame support in the pipeline, increase the contact area to ensure the stability of subsequent advancement, simultaneously realize synchronous power transmission at four positions, avoid winding and deviation in the pipeline due to unstable power output direction, and can correspondingly adjust the length of the driving components to facilitate the adjustment and use of different diameter pipelines, increase the equipment adaptation range, and quickly connect the cable with the central column by means of the assembly components to ensure the safety and stability of subsequent threading and avoid the risk of falling off.

[0004] However, in the above technical solution, the driving structure and the adjusting assembly are fixedly connected through the support column, which means that the position of the driving structure cannot be changed after the position adjustment of the adjusting assembly is completed. During cable laying in the pipeline, the inner wall of the pipeline is inevitably contaminated with some stains, resulting in protrusions on the inner wall of the pipeline. Since the position of the driving structure is fixed, these protruding stains will hinder the movement of the driving structure, causing problems in cable laying. Therefore, the adaptability and passability of the leading-through device are relatively low. UTILITY MODEL CONTENTS

During cable laying in the pipeline, the inner wall of the pipeline is inevitably contaminated with some stains, resulting in protrusions on the inner wall of the pipeline. Since the position of the driving structure is fixed, these protruding stains will hinder the movement of the driving structure, causing problems in cable laying. Therefore, the adaptability and passability of the leading-through device are relatively low.

[0011] As preferred, the rotating output part of the drive motor is connected with the drive wheel, and the second spring is fixedly connected with the T-shaped sliding block on one side.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) When the guide wheel encounters a protruding stain during the cable laying threading process, the protruding stain extrudes the guide wheel, so that the guide wheel moves to the center column, the guide wheel drives the T-shaped sliding block to move, the second spring deforms, the guide wheel can adapt to the protruding stain, when the guide wheel passes the protruding stain, the second spring rebounds, so that the guide wheel reattaches to the inner wall of the cable laying pipeline, facilitating continuous guiding, when the drive wheel encounters a protruding stain, the same as the above process, the guide wheel moves according to the slide column and the sliding slot, and the position of the drive wheel is self-adaptively changed according to the first spring, so that the adaptability and passability of the threading device can be improved.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1 As shown, a cable laying guide device includes a central column 1, a top cap 2 and a fixing collar 3 on the central column 1, a plurality of adjusting components 4 on the fixing collar 3, a sliding column 5 fixedly mounted on the adjusting components 4, a driving structure 6 on one side of the sliding column 5, a first spring 7 and a sliding groove 9 on the side of the driving structure 6 near the adjusting components 4, and a connecting member 8 on one side of the central column 1.

[0019] like Figure 2 As shown, in another embodiment of the present invention, the driving structure 6 includes a structural base 601, a driving motor 602 is fixedly installed on the structural base 601, a driving wheel 603 is rotatably arranged on one side of the structural base 601, and a T-shaped groove 604 is provided on one side of the structural base 601.

[0020] A T-shaped slider 605 is slidably disposed in the T-shaped groove 604. A second spring 606 is fixedly disposed on the inner wall surface of one side of the T-shaped groove 604. An extension platform 607 is disposed on one side of the T-shaped slider 605. A guide wheel 608 is rotatably disposed on the extension platform 607.

[0021] When the central column 1 needs to be moved by the drive structure 6, the drive motor 602 rotates the drive wheel 603, thereby moving the central column 1. The guide wheel 608 provides guidance. When the guide wheel 608 encounters a raised stain, the stain presses against the guide wheel 608, causing it to move towards the central column 1. The guide wheel 608 then moves the T-shaped slider 605, causing the second spring 606 to deform, allowing the guide wheel 608 to adapt to the raised stain. When the guide wheel 608 passes over the raised stain, the second spring 606 rebounds, causing the guide wheel 608 to re-fit against the inner wall of the cable laying pipe, facilitating continued guidance.

[0022] The working principle of the cable laying threading device is as follows:

[0023] In use, first, the position of the driving structure 6 is adjusted according to the size of the pipe according to the adjusting assembly 4, then the cable is fixed through the connecting piece 8, then the driving wheel 603 is rotated through the driving motor 602, so that the central column 1 is driven to move through the driving structure 6, and then the cable is moved through the central column 1, so that the cable is threaded, when the guide wheel 608 encounters a protruding stain, the protruding stain extrudes the guide wheel 608, so that the guide wheel 608 moves to the central column 1, the T-shaped sliding block 605 is driven to move by the guide wheel 608, the second spring 606 is deformed, so that the guide wheel 608 can adapt to the protruding stain, when the guide wheel 608 passes the protruding stain, the second spring 606 rebounds, so that the guide wheel 608 is reattached to the inner wall of the cable laying pipe, so as to facilitate the continuous guiding, when the driving wheel 603 encounters a protruding stain, the same as the above process, the movement is guided according to the slide column 5 and the sliding groove 9, and the position of the driving wheel 603 is self-adapted according to the first spring 7, so that the adaptability and passability of the threading device can be improved.

[0024] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, on the basis of the above description, other different forms of changes or variations can be made, and it is impossible to enumerate all the embodiments here, any obvious changes or variations derived from the technical solutions of the present application still fall within the protection scope of the present application.
