Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and specifically to a mine cable laying device. Background Art

[0002] Cable laying refers to the process of arranging cables at predetermined positions and paths according to certain technical specifications and standards to achieve power transmission or communication connection. This process involves multiple steps and technical details, including cable selection, path planning, laying methods, fixing, and identification.

[0003] A Chinese invention patent with the publication number CN113300274B discloses a cable laying device and its laying method, including: a base, symmetrically and fixedly connected with support legs at the bottom of the base, the support legs are rotatably connected with rollers through connected bearings, one end of the base is connected with a traction structure, the top of the base is fixedly connected with a support plate, a support groove is opened at the top of the support plate, and a winding roller for cable winding is movably connected in the support groove, the base is provided with a tensioning structure for cable tensioning on the right side wall of the support plate, the base is provided with a first guiding structure at the right end of the tensioning structure, an installation groove is opened at the right end of the first guiding structure of the base, the installation groove is connected with a second guiding structure, the base is connected with a pressing structure for cable pressing and a soil restoration structure for soil restoration at the right side of the installation groove; after the cable is laid in the present invention, it is not easy to deviate from the original position under external force, ensuring the actual cable laying.

[0004] In addition, during the cable laying process, due to the unwinding process and line errors, the laid cable is in a slack state, which may cause some parts of the cable to bend. This not only increases the friction between the bent cable and the guiding device during the laying process, but also results in the mismatch between the final laid cable length and the should-be-laid length, causing the use of extra cable and increasing resource consumption. In addition, since the existing cable is usually wound on a reel, the reel is rotatably arranged on a bracket and is in a free rotation state without providing driving force to it. Therefore, when quickly pulling the cable, it is easy to cause the reel to rotate too fast, resulting in excessive release of the cable, and the bent cable is prone to entanglement with the device during the pulling process. Therefore, the cable laying device and its laying method disclosed in Chinese invention patent CN113300274B cannot guarantee the release length of the cable and cannot straighten the bent cable.

A resisting surface 416 is formed on the side of the clamping block 415 away from the second sliding plate 411.

[0040] Driving the annular groove plate 45 through the second sliding plate 411 can clamp the cable wires 2 of various sizes. Clamping the cable wires 2 through the rollers 414 can achieve the effect of preliminary calibration of the bent cable wires 2.

[0041] The working process and principle of the above embodiment are as follows:

[0042] Initial state: The first spring 311 is in an uncompressed state, the limiting spring 49 is in an unextended state, and the second sliding plate 411 is at the innermost side of the guiding cylinder 43.

[0043] The working steps are as follows:

[0044] First, the operator winds the cable 2 around the outer wall of the sleeve rod 35, and installs the sleeve rod 35 and the cable 2 on the mounting block 32 provided on the bracket 31 through the cable bracket 34. Subsequently, the operator pulls one end of the cable 2, causing the cable 2 to move outward against the contact surface 416 towards the outside of the guide cylinder 43, so that the contact surface 416 drives the clamping block 415 to move synchronously towards the outside of the guide cylinder 43, causing the clamping block 415 to drive the contact groove plate 413 to move synchronously inside the guide cylinder 43, causing the contact groove plate 413 to drive the second slide plate 411 to move towards the outside of the second chute 44 inside the second chute 44, causing the second slide plate 411 to drive the contact rod 412 to move synchronously inside the third chute 46, and causing the contact rod 412 to contact the inner wall of the third chute 46, causing the contact rod 412 to move towards the side close to the first fixing block 47 inside the third chute 46, causing the annular groove plate 45 to start rotating under the contact action of the contact rod 412 and the third chute 46. Furthermore, the annular groove plate 45 drives the first fixing block 47 to rotate synchronously, causing the first fixing block 47 to drive the hinge block 48 to rotate synchronously, causing the hinge block 48 to drive the limiting spring 49 rotatably connected thereto to rotate synchronously, and causing the hinge block 48 to pull the limiting spring 49 to start stretching, causing the end of the limiting spring 49 rotatably connected to the second fixing block 410 to start rotating. Until the cable 2 passes through the guide cylinder 43 and the annular groove plate 45, at this time the annular groove plate 45 stops rotating, causing the cable 2 to contact the roller 414 under the elastic force generated by pulling the limiting spring 49 after the annular groove plate 45 rotates. Furthermore, the roller 414 squeezes the cable 2 by rolling; through the intermittent engagement of the first tooth block plate 312 and the second tooth block plate 313, the excessive rotation speed of the cable bracket 34 and the sleeve rod 35 in the natural rotation state is avoided, preventing the length of the cable 2 released from not matching the laying length, and avoiding the problem of resource waste caused by the excessive release of the cable 2, improving the effective utilization rate of the cable 2.

[0045] When the operator pulls the cable 2 wound around the outer wall of the sleeve rod 35, the cable 2 drives the sleeve rod 35 to rotate synchronously, the sleeve rod 35 drives the cable bracket 34 to rotate synchronously, the cable bracket 34 drives the first fixing rod 33 fixedly connected thereto to rotate synchronously, the first fixing rod 33 drives the mounting block 32 fixedly connected thereto to rotate synchronously, the first fixing rod 33 drives the second fixing rod 37 to penetrate and rotate inside the protective shell 36, the second fixing rod 37 drives the first chute 38 to rotate synchronously, the first chute 38 drives the first sliding plate 39 slidingly connected thereto to rotate synchronously, the first sliding plate 39 drives the first toothed plate 312 and the baffle 310 to rotate synchronously, the first toothed plate 312 abuts against the second toothed plate 313, the first toothed plate 312 moves toward the side close to the second fixing rod 37 under the abutting action of the second toothed plate 313, the first toothed plate 312 drives the first sliding plate 39 to slide into the first chute 38, the first sliding plate 39 drives the baffle 310 to move toward the side close to the second fixing rod 37, the baffle 310 squeezes the first spring 311 toward the side close to the second fixing rod 37, the first spring 311 contracts toward the side close to the second fixing rod 37 until the first toothed plate 312 moves to a position where it no longer abuts against the second toothed plate 313. At this time, the first spring 311 drives the first sliding plate 39 to slide inside the first chute 38 through the baffle 310, and the first sliding plate 39 drives the first toothed plate 312 to move away from the second fixing rod 37; the intermittent clamping between the first toothed plate 312 and the second toothed plate 313 and the elastic force after the stretching of the limiting spring 49 drive the roller 414 to initially stretch the cable 2, and the roller 414 straightens the cable 2 in a rolling manner, avoiding excessive friction between the released bent cable 2 and the guiding device, reducing the physical strength consumed by the operator when pulling the cable 2, and thus reducing the difficulty of laying the cable 2. This not only ensures the quality of the laid cable 2 but also improves the laying efficiency of the cable 2.

[0046] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
