[0002] With the development of the cable industry, various wire pay-off racks have emerged as the times require. The wire pay-off rack is mainly applicable to supporting the wire reel to pay off wires during line construction. When guiding the wire and the ground wire, the wire reel can rotate automatically to unwind. According to the lifting form, it can be divided into a hydraulic cable pay-off rack or a mechanical cable support rack.

[0003] In actual work, the structure and function of the existing wire pay-off rack are relatively perfect and can meet the daily use requirements, but there are still the following problems:

[0004] In the actual use process, when the cables on the wire pay-off rack are wound and unwound, they will become loose, which will cause the cables to be randomly wound on the winding frame, resulting in the cables being knotted and unable to be wound and unwound. Moreover, the loose cables will increase the winding area, making it impossible to neatly store the cables on the wire pay-off rack.

[0005] Therefore, the utility model provides a wire pay-off rack with an automatic winding and unwinding function. Summary of the Utility Model

Detailed Embodiment

[0028] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1-4 shown, this embodiment provides a technical solution: a wire reel with an automatic retracting and releasing function, including a base 1, and mounting plates 2 are symmetrically and fixedly connected to the top of the outer surface of the base 1; a wire limiting and pressing structure 3 is arranged on one side and the top of one of the mounting plates 2; a transmission retracting and releasing structure 4 is arranged between the two mounting plates 2; the wire limiting and pressing structure 3 includes a connecting rod 31, one end of the connecting rod 31 is fixedly connected to one of the mounting plates 2, the other end of the connecting rod 31 is fixedly connected to a mounting auxiliary plate 32, a first fixing rod 33 is fixedly connected to the bottom of the outer surface of the mounting auxiliary plate 32, the bottom end of the first fixing rod 33 is slidably connected to a first sliding cylinder 34, and a first arc-shaped pressing plate 36 is fixedly connected to the bottom of the outer surface of the first sliding cylinder 34.

[0030] By setting the first fixing rod 33 and the first sliding cylinder 34, it can cooperate with the first spring 35 and the first arc-shaped pressing plate 36, and further can assist in limiting the cable on the first wire spool 44. At the same time, under the action of the second fixing rod 39 and the second sliding cylinder 310, it can cooperate with the second spring 312 and the second arc-shaped pressing plate 311, and further can assist in limiting the cable on the second wire spool 414, avoiding the situation of cable slack during the retracting and releasing process. Under the action of the first motor 41, it can cooperate with the circular clamping frame 42 and the circular clamping block 46, and further can drive the first wire spool 44 by the motor. At the same time, the first wire spool 44 can be manually driven. Under the action of the second wire spool 414, it can cooperate to make the cable not slack during the retracting and releasing process.

[0031] Even further, as Figure 2As shown: A first spring 35 is sleeved on the outer surface of the first fixing rod 33. Two ends of the first spring 35 are respectively fixedly connected to the first sliding cylinder 34 and the installation auxiliary plate 32. One side of the outer surface of the installation auxiliary plate 32 is fixedly connected with a connecting arc rod 37. One end of the connecting arc rod 37 is fixedly connected with a circular connecting block 38. The bottom end of the circular connecting block 38 is fixedly connected with a second fixing rod 39. The bottom end of the second fixing rod 39 is slidably connected with a second sliding cylinder 310. The bottom of the outer surface of the second sliding cylinder 310 is fixedly connected with a second arc-shaped pressing plate 311. A second spring 312 is sleeved on the outer surface of the second fixing rod 39. Two ends of the second spring 312 are respectively fixedly connected to the second sliding cylinder 310 and the circular connecting block 38. Under the action of the first sliding cylinder 34 and the first fixing rod 33, in cooperation with the first spring 35 and the first arc-shaped pressing plate 36, the cables on the first wire winding frame 44 can be assisted in being limited. Under the action of the second fixing rod 39 and the second sliding cylinder 310, in cooperation with the second spring 312 and the second arc-shaped pressing plate 311, the cables on the second wire winding frame 414 can be assisted in being limited, avoiding slackness.

[0032] In the above solution, there is also a problem that the first wire winding frame 44 can only be driven electrically or manually. Electric drive is limited by electricity, and manual drive is very laborious. For example Figure 3 and Figure 4 As shown: In this solution, the transmission winding and unwinding structure 4 includes a first motor 41. The first motor 41 is fixedly connected to one of the mounting plates 2. The output end of the first motor 41 is fixedly connected with a circular clamping frame 42. The inner wall of the other mounting plate 2 is rotatably connected with a rotating rod 43. The outer surface of the rotating rod 43 is fixedly connected with a first wire winding frame 44. One end of the outer surface of the rotating rod 43 is fixedly connected with an operation block 45. The other end of the rotating rod 43 is fixedly connected with a circular clamping block 46. The circular clamping block 46 is arranged without contact inside the circular clamping frame 42. The inner wall of the circular clamping frame 42 is provided with a first insertion hole 47. The inner wall of the circular clamping block 46 is provided with a second insertion hole 48. A threaded insertion rod 49 is inserted into the inner walls of the first insertion hole 47 and the second insertion hole 48. One end of the threaded insertion rod 49 is threadedly connected with a fixing nut 410. Under the action of the circular clamping block 46 and the circular clamping frame 42, it can cooperate with the first motor 41 to drive and rotate. At the same time, under the action of the first insertion hole 47 and the second insertion hole 48, in cooperation with the threaded insertion rod 49, it can be driven by the motor or manually driven by the rotating rod 43, thereby driving the first wire winding frame 44 to rotate, and then winding and unwinding the cables.

[0033] In the above solution, there is also a problem that the cables on the first wire winding frame 44 are prone to slack during the winding and unwinding process. For example Figure 3As shown in the figure, on one side of the outer surface of two mounting plates 2, there is a fixedly connected mounting rectangular plate 411. On one side of the outer surface of one of the mounting rectangular plates 411, a second motor 412 is fixedly installed. The output end of the second motor 412 is fixedly connected to a transmission rod 413. The outer surface of the transmission rod 413 is fixedly connected to a second wire winding frame 414. Under the action of the second motor 412 and the transmission rod 413, the second wire winding frame 414 can be driven to rotate, and then it can cooperate with the first wire winding frame 44 to assist in winding and unwinding the cable, avoiding the situation of the cable becoming slack during the winding and unwinding process.

[0034] Working principle:

[0035] As Figures 1-4 shown:

[0036] During use: When electric drive is required, at this time, insert the threaded insertion rod 49 into the inside of the first jack 47 and the second jack 48, and then assist in fixing the fixing nut 410 to the threaded insertion rod 49. At this time, start the first motor 41, so that the first motor 41 can drive the rotating rod 43 to rotate, and then drive the first wire winding frame 44 to rotate;

[0037] At this time, the second motor 412 can be started, so that the second motor 412 can drive the transmission rod 413 and the second wire winding frame 414 to rotate, and then assist in winding and unwinding the cable;

[0038] When manual drive is required, at this time, pull out the threaded insertion rod 49, and then rotate the operation block 45, so that the rotating rod 43 can rotate, and then drive the first wire winding frame 44 to rotate;

[0039] When winding and unwinding the cable, at this time, the first arc-shaped pressing plate 36 can drive the first sliding cylinder 34 to slide on the outer surface of the first fixed rod 33 under the action of the first spring 35, and the second arc-shaped pressing plate 311 can drive the second sliding cylinder 310 to slide on the outer surface of the second fixed rod 39 under the action of the second spring 312, so as to limit the cable on the first wire winding frame 44 by the first arc-shaped pressing plate 36 and limit the cable on the second wire winding frame 414 by the second arc-shaped pressing plate 311.

[0040] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
