Description

Technical Field

[0001] The utility model relates to a rapid cable laying device, belonging to the technical field of cable laying. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the application scenario, it can be divided into several laying methods, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying methods is very important to ensure the transmission quality, reliability and construction maintenance of the line. In the process of laying the cable, the cable on the ground needs to be inserted from the wellhead, and then the cable is pulled and laid in the underground pipe network. In the process of inserting the cable on the ground into the underground cable channel, the cable will cause friction with the edge of the wellhead, so cable laying equipment will be used to prevent friction on the cable.

[0003] Publication No.: CN214429112U, mentions a cable rapid laying device. During the laying process of the cable, the cable can be rolled and conveyed through the first conveying roller, the second conveying roller and the third conveying roller in sequence. In this way, in the process of passing the cable on the ground into the shaft opening of the underground cable channel, the cable can be prevented from rubbing against the edge of the shaft opening, thereby avoiding the phenomenon of cable sheath damage caused by friction, thereby ensuring the service life of the cable. However, no limiting structure is set on the surface of the first conveying roller, the second conveying roller and the third conveying roller in the device. When the cable is laid on its surface, it is easy to move forward and backward and fall off. Now there is an urgent need for a rapid cable laying device to solve the above-mentioned problems.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a fast cable laying device, including a laying frame 1, a sliding frame 7, a fixed block 8 and an extension bolt 13. The upper ends of the front and rear sides of the laying frame 1 are both provided with mounting side grooves 3, and the lower ends of the two mounting side grooves 3 are both installed with damping shock absorbers 4. The fixed ends of the two damping shock absorbers 4 are both installed with spring seats 5. The upper ends of the two spring seats 5 are both installed with springs 6. Two sliding frames 7 are provided, and the two sliding frames 7 are respectively slid in the two mounting side grooves 3. Two fixed blocks 8 are provided, and the two fixed blocks 8 are respectively fixed to the lower ends of the two sliding frames 7. The inner sides of the two fixed blocks 8 are both installed with first bearing seats 9, and the inner rings of the two first bearing seats 9 are A first limiting roller 10 is installed, and a plurality of first cable limiting rings 11 are fixed on the annular side surface of the first limiting roller 10. Ball bearing seats 12 are installed on the upper ends of the two fixed blocks 8. Sliding blocks 14 are movably provided on the upper ends of the two sliding frames 7. Second bearing seats 15 are installed on the inner sides of the two sliding blocks 14. A second limiting roller 16 is installed between the inner circles of the two second bearing seats 15. A plurality of second cable limiting rings 17 are fixed on the annular sides of the two second limiting rollers 16. Two extension bolts 13 are provided. This design solves the problem that no limiting structure is provided on the surface of each conveying roller in the original device, and when the cable is laid on its surface, it is easy to move forward and backward and fall off.

[0019] As the first embodiment of the utility model: inclined reinforcement rods 2 are installed on the front and rear sides of the left end of the laying frame 1. The added inclined reinforcement rods 2 can improve the stability of the laying frame 1 installed at the external shaft opening. A limiting groove is provided on the lower side of the right end of the laying frame 1, and a plurality of return springs are installed on the left end of the limiting groove, and a movable baffle is installed on the right end of the plurality of return springs. The added plurality of return springs and movable baffles can prevent the cable from making hard contact with the laying frame 1 when the cable falls downward into the external shaft opening. The two springs 6 are respectively sleeved on the outside of the movable ends of the two damping shock absorbers 4, and the upper ends of the two springs 6 and the movable ends of the two damping shock absorbers 4 are respectively fixed to the two sliding frames 7. The added two damping shock absorbers 4 and two springs 6 can provide a buffering effect for the two sliding frames 7.

[0020] The plurality of second cable limiting rings 17 are respectively located directly below the plurality of first cable limiting rings 11. The cables between the first limiting roller 10 and the second limiting roller 16 can be limited and prevented from falling off by the added plurality of second cable limiting rings 17 and the plurality of first cable limiting rings 11. The two lengthening bolts 13 respectively pass through the upper ends of the two sliding frames 7, and the two lengthening bolts 13 pass through the two sliding blocks 14 through the thread principle. The lower ends of the two lengthening bolts 13 are respectively installed in the inner rings of the two ball bearing seats 12. When the two added lengthening bolts 13 are screwed, the two sliding blocks 14 can be driven downward through the thread principle, thereby adjusting the spacing between the first limiting roller 10 and the second limiting roller 16.

[0021] As the second embodiment of the utility model: first, the device is moved to the external well entrance, and then the laying frame 1 is fixed to the two inclined reinforcement rods 2 by external bolts, and then the cable is passed through the top of the first limit roller 10 so that it is between multiple first cable limit rings 11, and then the two extension bolts 13 are screwed at the same speed and in the same direction (Note: the threaded parts of the two extension bolts 13 are not in contact with the upper end of the sliding frame 7). The two extension bolts 13 can drive the two ball bearing seats 12 to rotate in situ, and then the two sliding blocks 14 are driven to move downward in the two sliding frames 7 through the thread principle, thereby driving the second limit roller 16 to move downward until the multiple first cable limit rings 11 contact the first cable limit ring 11, so that they can limit the cable together, and the cable can be laid. In this process, when the cable is subjected to excessive pulling force, the pressure will be transmitted downward, and transmitted to the active end of the damping shock absorber 4 and the spring 6 through the first limit roller 10, the first bearing seat 9, the fixed block 8 and the sliding frame 7 to slow down the absorption.
