Description

Technical Field

[0001] This utility model relates to the field of wire feeding frame technology, specifically a wire feeding frame anti-stretching device. Background Technology

[0002] With the acceleration of urbanization and the continuous development of the economy, power transmission networks are constantly expanding, and information infrastructure such as communication base stations and data centers are also being built on a large scale. These projects all require the laying of a large number of cables, such as high-voltage transmission cables and communication fiber optic cables. In the process of cable laying, cable laying frames are essential equipment used to support and release cables. In the construction of various infrastructure projects, safe production is always of paramount importance. Safety issues in cable construction are directly related to the life safety of construction workers and the smooth progress of the project. Anti-stretching devices can effectively reduce safety hazards caused by improper cable stretching, meet the requirements of safe production, and therefore have received widespread attention and application.

[0003] When using the anti-stretching device on a cable laying frame, traditional cable laying frames typically place and rotate the cable reel, providing only simple assistance in cable laying. During the laying process, the cable is prone to being overstretched, resulting in uneven stretching or jamming. Construction workers need to spend extra time and effort to handle these issues, reducing the equipment's efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a cable laying frame anti-stretching device to solve the problems mentioned in the background art. Traditional cable laying frames generally place and rotate the cable drum through a placement frame, which only has a simple auxiliary effect on cable laying. During the cable laying process, the cable is easily overstretched, and the cable is prone to uneven stretching or jamming. Construction workers need to spend extra time and effort to deal with this, which reduces the working efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire-laying frame anti-stretching device, comprising a fixed base plate, wherein adjusting grooves are provided on the top of the fixed base plate near the front and rear edges, and a sliding frame is slidably connected between the two adjusting grooves; a fixed frame is fixedly connected on the top of the fixed base plate near one edge; two telescopic rods are fixedly installed on the outer surface of the opposite side of the fixed frame and the sliding frame near the bottom edge; a first spring is installed on the outer surface of the two telescopic rods near the center; mounting holes are provided on the outer surface of the opposite side of the sliding frame and the fixed frame near the center; and a rotating rod is rotatably arranged between the two mounting holes.

[0006] In a preferred embodiment, a first ratchet is fixedly sleeved on the outer surface of the rotating rod near one end of the edge, and three fixing blocks are fixedly arranged at equal intervals along the circumferential direction on the other side of the outer surface of the first ratchet.

[0007] In a preferred embodiment, a threaded groove is provided on the outer surface of the rotating rod near the edge of the other end, and a second ratchet is threaded onto the outer surface of the threaded groove.

[0008] In a preferred embodiment, a wire feeding wheel is slidably sleeved on the outer surface of the rotating rod near the center. Three locking holes are equidistantly opened on one side of the outer surface of the wire feeding wheel stop block along the circumferential direction, and the locking holes correspond to the fixing blocks.

[0009] In a preferred embodiment, a stop pawl is rotatably provided at the top edge of the fixed base plate near the rear side, and the pawl of the stop pawl and the first ratchet mesh with the ratchet teeth of the second ratchet.

[0010] In a preferred embodiment, a second spring is fixedly welded to the top of the fixed base plate near the edge of the stop claw block, and the top of the second spring is fixedly welded to the protrusion of the stop claw block.

[0011] In a preferred embodiment, a fixing plate is fixedly connected to the front outer surface of the fixing frame near the top edge, and a cable limiting hole is provided on the front outer surface of the fixing plate near one side edge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention first involves mounting the pay-off reel onto the outer surface of the rotating rod using a rotating rod, ensuring the engaging hole engages with the fixing block. After installation, the second ratchet is threaded onto the rotating rod via a threaded groove. Moving the sliding bracket outwards causes it to slide within the adjusting groove. This outward movement pulls the telescopic rod and the first spring outwards. When the outward movement stops, the continuous inward force of the first spring causes the sliding bracket to retract inwards. The rotating rod is then installed through the mounting holes on the sliding bracket and the fixing bracket, engaging the stop pawl and the ratchet teeth of the first and second ratchets, thus winding the wire onto the pay-off reel. The wire and cable can be pulled out and passed through the cable limiting hole for use. By pulling the wire and cable, the wire feeding reel can be rotated clockwise. Through the engagement of the locking hole and the fixing block, the rotation of the wire feeding reel can drive the first ratchet, the rotating rod and the second ratchet to rotate synchronously. The engagement of the stop pawl block and the ratchet teeth of the first and second ratchet wheels can limit the reverse rotation of the wire feeding reel. The continuous inward contraction force of the second spring can more effectively engage the stop pawl block and the ratchet teeth of the first and second ratchet wheels, thereby limiting the clockwise rotation speed of the wire feeding reel and preventing the cable from being overstretched during the wire feeding process, thus improving the working efficiency of the equipment.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a wire-laying frame anti-stretching device, including a fixed base plate 1. Adjustable grooves 2 are provided on the top of the fixed base plate 1 near the front and rear edges. The sliding frame 3 can slide left and right through the adjustable grooves 2. The sliding frame 3 is slidably connected between the two adjustable grooves 2. The sliding of the sliding frame 3 allows for easier installation of a rotating rod 8 between the sliding frame 3 and a fixed frame 4 through mounting holes 7. A fixed frame 4 is fixedly connected to the top of the fixed base plate 1 near one edge. Two telescopic rods 5 are fixedly installed near the bottom edge between the outer surfaces of the fixed frame 4 and the sliding frame 3 on opposite sides. The telescopic rods 5 make the sliding of the sliding frame 3 more stable. Each telescopic rod 5 has a first spring 6 installed near the center on its outer surface. When the sliding frame 3 slides outward, it can pull the telescopic rod 5 and the first spring 6 outward. When the sliding frame 3 stops sliding outward, the continuous inward force of the first spring 6 will cause the sliding frame 3 to retract inward, thus making the installation of the rotating rod 8 more stable. The outer surface of the opposite side of the sliding frame 3 and the fixed frame 4 is provided with mounting holes 7 near the center. The rotating rod 8 can be installed between the sliding frame 3 and the fixed frame 4 through the mounting holes 7. The rotating rod 8 is rotatably installed between the two mounting holes 7. The wire feeding wheel 13 can be sleeved through the rotating rod 8, and when the rotating rod 8 rotates, it can drive the first ratchet 9 to rotate.

[0022] A first ratchet 9 is fixedly fitted onto the outer surface of the rotating rod 8 near one end. Rotation of the first ratchet 9 drives the fixed locking block 10 to rotate circumferentially. Three fixed locking blocks 10 are equidistantly fixed along the circumferential direction on the other side of the outer surface of the first ratchet 9. These fixed locking blocks 10 can engage with the locking hole 14. A threaded groove 11 is provided on the outer surface of the rotating rod 8 near the other end. The second ratchet 12 can be threadedly installed through the threaded groove 11. The outer surface of the threaded groove 11 is threadedly connected to the second ratchet 12. The wire feeding wheel 13 can be stably sleeved on the outer surface of the rotating rod 8. The wire feeding wheel 13 is slidably sleeved on the outer surface of the rotating rod 8 near the center. The rotation of the wire feeding wheel 13 can drive the wire and cable sleeved on the outer surface of the wire feeding wheel 13 to feed the wire. Three locking holes 14 are equidistantly opened on one side of the outer surface of the stop block on one side of the wire feeding wheel 13 along the circumferential direction. The locking holes 14 correspond to the fixing block 10. The locking holes 14 can be locked with the fixing block 10. Thus, when the wire feeding wheel 13 rotates, it can drive the rotating rod 8, the first ratchet 9 and the second ratchet 12 to rotate.

[0023] A stop pawl 15 is rotatably mounted on the top of the fixed base plate 1 near the rear edge. The pawl of the stop pawl 15 and the first ratchet 9 mesh with the ratchet teeth of the second ratchet 12. Through the meshing of the stop pawl 15 and the first ratchet 9 with the ratchet teeth of the second ratchet 12, the reverse rotation of the pay-off reel 13 can be restricted. A second spring 16 is fixedly welded to the top of the fixed base plate 1 near the edge of the stop pawl 15, and the top of the second spring 16 is fixedly welded to the protrusion of the stop pawl 15. The continuous inward contraction force of the second spring 16 can... To more effectively engage the stop pawl block 15 and the first ratchet 9 with the ratchet teeth of the second ratchet 12, thereby limiting the clockwise rotation speed of the wire feeding wheel 13 and preventing the cable from being overstretched during the wire feeding process, a fixing plate 17 is fixedly connected to the front outer surface of the fixing frame 4 near the top edge. A cable limiting hole 18 is provided on the front outer surface of the fixing plate 17 near one side edge. The direction of pulling the wire and cable can be controlled by the setting of the fixing plate 17 and the cable limiting hole 18, making the wire feeding process more stable.

[0024] Working principle: When using the anti-stretching device for the wire feeding frame, firstly, the wire feeding wheel 13 is fitted onto the outer surface of the rotating rod 8 via the rotating rod 8, and the engaging hole 14 is engaged with the fixed block 10. After installation, the second ratchet 12 is threaded onto the rotating rod 8 via the threaded groove 11. By pushing the sliding frame 3 outward, the sliding frame 3 slides outward within the adjusting groove 2. When the sliding frame 3 slides outward, it can drive the telescopic rod 5 and the first spring 6 to pull outward. When the outward sliding of the sliding frame 3 stops, the continuous inward force of the first spring 6 will drive the sliding frame 3 to retract inward. The rotating rod 8 is installed through the mounting hole 7 on the fixed frame 4, and the stop pawl block 15 and the first ratchet 9 engage with the ratchet teeth of the second ratchet 12, thus... The wire and cable wound on the pay-off reel 13 are pulled out and passed through the cable limiting hole 18, ready for use. By pulling the wire and cable, the pay-off reel 13 can be rotated clockwise. Through the engagement of the locking hole 14 and the fixing block 10, the rotation of the pay-off reel 13 can drive the first ratchet 9, the rotating rod 8 and the second ratchet 12 to rotate synchronously. Through the engagement of the stop pawl block 15 and the ratchet teeth of the first ratchet 9 and the second ratchet 12, the reverse rotation of the pay-off reel 13 can be restricted. The continuous inward contraction force of the second spring 16 can more effectively make the stop pawl block 15 and the ratchet teeth of the first ratchet 9 and the second ratchet 12 engage, thereby limiting the clockwise rotation speed of the pay-off reel 13, preventing the cable from being overstretched during the pay-off process, and improving the working efficiency of the equipment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
