Description

Technical Field

[0001] This utility model relates to the field of cable laying support technology, specifically to an auxiliary cable laying support. Background Technology

[0002] Cable laying refers to the process of laying and installing cables in a surveyed area to form a cable line. A cable reel is a reel used to collect and release cables. Power cables are generally transported, stored, and laid while wound on cable reel. A cable reel frame is a device used to rotate the cable reel. During cable laying operations, the cable needs to be pulled out from the cable reel; this process involves the cable reel rotating on the cable reel frame to perform the cable release operation.

[0003] For example, the utility model patent with publication number CN221102897U discloses an automatic cable laying bracket for cable laying, including a base, a groove on the upper surface of the base, a feeding structure inside the groove, a laying roller inside the feeding structure, connecting shafts fixedly installed at both ends of the laying roller, and four sets of fixing structures inside the base located on both sides of the groove. This utility model, through the design of a feeding structure, involves rotating the first turntable according to the length of the feeding roller, driving the first lead screw to rotate, thereby causing the second slider to slide inside the groove to expand or reduce the distance between the two sets of columns. Then, the connecting shafts at both ends of the feeding roller are inserted into the lifting platform along the groove, and the jack is activated to move the lifting platform and the first slider upwards along the columns, thus lifting the feeding roller. This simplifies the installation steps of the feeding roller, saves installation time, and improves the efficiency of the feeding operation. It can also be adapted to different feeding rollers, reducing the cost of the feeding support. However, there is a problem: when using the feeding roller for the feeding action, it causes the feeding roller to rotate, which generates vibration during the process, causing the first lead screw to rotate. This can cause the symmetrically arranged pressure platforms to move away from each other, ultimately resulting in the feeding roller detaching from the lifting platform, reducing the stability and efficiency of the feeding process. Therefore, we propose an auxiliary feeding frame for cable laying. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4This utility model provides a technical solution: a cable laying auxiliary cable laying frame, including a movable seat 1 and locking casters 4. A dovetail groove 3 is provided in the middle of the upper end of the movable seat 1. A cable laying support mechanism 5 is provided in the middle of the upper end of the movable seat 1. The cable laying support mechanism 5 includes a first support plate 510 and a second support plate 512. A cable laying roller assembly 6 is provided on the upper side of the first support plate 510 and the second support plate 512. The cable laying roller assembly 6 is used for cable laying. The cable laying support mechanism 5 is used to support the cable laying roller assembly 6 and adjust its height.

[0023] In this embodiment, the wire feeding support mechanism 5 includes a stepper motor 51. The movable seat 1 is fixedly installed at one end of the stepper motor 51 near the movable seat 1. A first rotating rod 52 is fixedly installed at the output end of the stepper motor 51. The end of the first rotating rod 52 away from the stepper motor 51 is rotatably connected to the movable seat 1 through a bearing. Two symmetrically arranged dovetail blocks 53 are threadedly connected to the outer end of the first rotating rod 52. A movable plate 54 is fixedly installed at the upper end of each dovetail block 53. The lower end of the movable plate 54 is slidably connected to the movable seat 1. A fixing strip 55 is fixedly installed at the upper end of each movable plate 54. A sliding groove 56 is opened at one end of each of the two fixing strips 55 close to each other. A second rotating rod 57 is rotatably connected to the bottom inner wall of each sliding groove 56 through a bearing. A slider 59 is threadedly connected to the outer end of the second rotating rod 57. A first support plate 510 is fixedly installed at the inner end of the slider 59. A first overlapping groove 511 is opened on the surface of the first support plate 510.

[0024] Specifically, when the wire feeding roller assembly 6 needs to be placed, the follower shaft 61 can be placed into the two first overlapping grooves 511. At this time, the first support plate 510 supports the wire feeding roller assembly 6, and the two ends of the follower shaft 61 also overlap into the second overlapping grooves 513. At this time, the cable on the wire feeding roller body 62 can be pulled. When the height of the wire feeding roller body 62 needs to be adjusted, the stepper motor 51 can be started. The output end of the stepper motor 51 drives the first rotating rod 52 to rotate, which in turn drives the two symmetrically arranged dovetail blocks 53 to move away from each other. At this time, the dovetail blocks 53 drive the moving plate 54, the fixing bar 55, the second rotating rod 57, the operating handle 58, and the slider. 59. The first support plate 510 and the second support plate 512 move. When the follower shaft 61 disengages from the second overlapping groove 513 but remains in the first overlapping groove 511, the two operating handles 58 can be rotated in opposite directions. Each operating handle 58 drives the second rotating rod 57 to rotate, thereby driving the slider 59 to slide in the slide groove 56. The slider 59 drives the first support plate 510 to move upward. When the moved first support plate 510 corresponds to the second support plate 512, the stepper motor 51 is started again. At this time, the output end of the stepper motor 51 drives the first rotating rod 52 to rotate. The first rotating rod 52 drives the dovetail block 53 to move closer to each other in the dovetail groove 3.

[0025] In this embodiment, each fixing strip 55 has a plurality of vertically distributed second support plates 512 fixedly installed on its right end, and each second support plate 512 has a second overlapping groove 513 on its surface.

[0026] Specifically, the second support plate 512 can support the follower shaft 61 that will subsequently lay out the wires.

[0027] In this embodiment, the wire feeding roller assembly 6 includes a follower shaft 61, and a wire feeding roller body 62 is fixedly installed at the middle of the outer end of the follower shaft 61. A blocking circular plate 63 is fixedly installed at both the front and rear ends of the wire feeding roller body 62.

[0028] Specifically, the cable wound around the outer end of the cable-feeding roller body 62 can be pulled by the cable-feeding roller assembly 6. At this time, the cable drives the cable-feeding roller body 62 to rotate, which in turn drives the follower shaft 61 and the blocking circular plate 63 to rotate.

[0029] In this embodiment, the outer end of the second rotating rod 57 is provided with a threaded groove, and the outer end of the slider 59 is slidably connected to the slide groove 56.

[0030] Specifically, this ensures that the slider 59 can slide stably within the groove 56.

[0031] In this embodiment, the outer end of the first rotating rod 52 has two symmetrically arranged threaded grooves, and the first rotating rod 52 passes through the dovetail block 53.

[0032] Specifically, it ensures that the dovetail block 53 can continuously move along the first rotating rod 52 during the movement.

[0033] In this embodiment, each corner of the lower end of the movable seat 1 is equipped with a locking universal wheel 4, and trapezoidal blocks 2 are fixedly installed on both sides of the movable seat 1. The two trapezoidal blocks 2 are tilted at one end away from each other.

[0034] Specifically, the locking caster 4 can support and move the movable seat 1, while the trapezoidal block 2 can reduce the probability of interference between the cable and the movable seat 1.

[0035] In this embodiment, an operating handle 58 is fixedly installed on the upper end of the second rotating rod 57, and a fixing strip 55 is rotatably connected to the lower end of the operating handle 58.

[0036] Specifically, the second rotating rod 57 can be directly operated by operating the handle 58.

[0037] Working principle: When the wire feeding roller assembly 6 needs to be placed, the follower shaft 61 can be placed into the two first overlapping grooves 511. At this time, the first support plate 510 supports the wire feeding roller assembly 6. At this time, both ends of the follower shaft 61 are also overlapped in the second overlapping grooves 513. At this time, the cable on the wire feeding roller body 62 can be pulled. When the height of the wire feeding roller body 62 needs to be adjusted, the stepper motor 51 can be started. At this time, the output end of the stepper motor 51 drives the first rotating rod 52 to rotate, which in turn drives the two symmetrically arranged dovetail blocks 53 to move away from each other. At this time, the dovetail blocks 53 drive the moving plate 54, the fixing strip 55, the second rotating rod 57, the operating handle 58, and the sliding plate 54. Block 59, the first support plate 510, and the second support plate 512 move. When the follower shaft 61 disengages from the second overlapping groove 513 but remains within the first overlapping groove 511, the two operating handles 58 can be rotated in opposite directions. Each operating handle 58 drives the second rotating rod 57 to rotate, thereby driving the slider 59 to slide within the slide groove 56. The slider 59 drives the first support plate 510 to move upward. When the moved first support plate 510 corresponds to the second support plate 512, the stepper motor 51 is restarted. The output of the stepper motor 51 drives the first rotating rod 52 to rotate, and the first rotating rod 52 drives the dovetail block 53 to move closer to each other within the dovetail groove 3.
