Description

Technical Field

[0001] The present invention relates to the field of cable retraction control, and particularly to a clutch type automatic retraction system. Background Art

[0002] With the modernization drive in China, further exploration of marine resources, development of urban subways, and increasing depth of oil and gas energy extraction, there is a further need for long-distance wired communication in deep sea and deep well, underground tunnel construction, and special robots. The towed array is growing longer. To ensure good communication of equipment, a stable long-distance transmission communication is required, and the cable reel is the main equipment to ensure the normal operation of long-distance wired communication of machines.

[0003] In actual engineering practice, the following problems exist:

[0004] First, the existing electric cable retraction does not pay attention to the change of cable tension. The tension of cable retraction is likely to be too large or too small. Excessive cable tension may cause problems such as overall deformation and surface wrinkles of the cable, while too small cable tension may cause loose winding and abnormal retraction. For example, when the cable is being wound, the winding radius of the cable on the reel gradually increases from small to large. If the rotation speed of the cable retraction and winding reel motor is constant, the winding speed of the cable at the beginning of winding onto the reel gradually increases, and the working load and speed change of the other end of the cable are unknown, resulting in possible tension fluctuations of the cable. To control the tension on the cable rope, there are usually two ideas: one is to control the speed difference before and after cable retraction, and the other is to control the output torque of the cable reel motor. However, these two solutions require servo feedback technology, which is a precision technology with high cost and low service life.

[0005] Second, the solution in the above first point uses the spring force to reduce tension fluctuations and provides tension compensation. However, there are still improvement points in actual use: when the cable initially acts on the spring under tension, it is a linear force, and this force transition is gentle and the action is stable. But when the spring rebounds, the action is large and rapid, and there will still be certain tension fluctuation problems, which will affect the cable itself and the collision between the cable and other components.

[0006] Third, the auxiliary control equipment of the cable in the prior art, such as rollers, etc., is often a separate bracket structure. More component numbers require multiple bracket structures, resulting in a large amount of manpower and material resources in the procurement, transportation, and assembly links.

[0007] Fourth, during the cable retraction process in the prior art, there is often a certain distance between the cable reel end and the other end of the cable, and it is difficult to accurately align the two. Inaccurate alignment may cause cable deviation, and the solution may require higher-cost and more precise instruments. Summary of the Invention

[0008] To overcome the above problems, the present invention proposes a solution to simultaneously solve the above-mentioned multiple problems.

[0009] The technical solution adopted by the present invention to solve its technical problems is: a clutch-type automatic retracting and deploying system, including a driving device, a clutch device, a drum assembly, a sliding table, a cable control module, and a pulley module. The cable on the drum assembly is led out and sequentially passes through the cable control module and the pulley module. The pulley module includes a vertical frame and a pulley group. The clutch device includes a housing, a switching rod, a driving shaft, a first half clutch, a centering ring, and a second half clutch. The housing is provided with a gear position groove. The switching rod can move along the gear position groove. The lower end of the switching rod is provided with a ring portion, and the ring portion is nested on the outer surface of the first half clutch. The first half clutch is internally provided with an opening to accommodate the driving shaft. The first half clutch and the second half clutch can be engaged or disengaged by moving. The driving shaft is provided with a key, and the first half clutch is provided with a key groove. The key groove and the key can be combined or disengaged by moving the first half clutch. The end of the driving shaft is sleeved with the centering ring. The power shaft of the driving device is fixedly connected to the second half clutch.

[0010] The cable control module includes a main support module, a sub-support module, a spring adjustment module, a driving roller group, and a vertical roller group. The main support module includes an upper plate, two side plates, and a bottom plate. The sub-support module includes a frame body, an upper extension plate, and a lower extension plate. The spring adjustment module includes a spring rod, a spring, a top plate, a left vertical plate, a right vertical plate, a square ring, a support plate, a support portion, and a counterweight.

[0011] The drum assembly is fixed on a chassis. One end of a connecting frame is also fixed on the chassis. The connecting frame is inclined. The other end of the connecting frame is connected to the sliding table. The main support module is arranged above the sliding table, and the main support module can move along the sliding table. Two side plates are arranged above the bottom plate, and the upper ends of the two side plates are connected by the upper plate. The upper plate is provided with a first through hole. The frame body is fixed with an upper extension plate and a lower extension plate, and both the upper extension plate and the lower extension plate are fixed between the two side plates. The upper extension plate is provided with a second through hole. The spring rod passes through the first through hole and the second through hole. The spring is sleeved on the spring rod. The upper end of the spring rod is fixed with a top plate. The upper end of the spring abuts against the top plate, and the lower end abuts against the upper plate.

[0012] A horizontally arranged driving roller group is arranged in the frame body, and a vertical roller group is arranged between the upper extension plate and the lower extension plate. The upper extension plate is provided with a long hole to adjust the distance between the two rollers of the vertical roller group. The shaft of one roller in the vertical roller group is accommodated in the long hole.

[0013] The lower surface of the upper extension plate is connected with a left vertical plate and a right vertical plate. The lower end of the spring rod is connected with a square ring, and the lower end of the square ring is connected with the support plate. Support parts are arranged at the lower ends of the left vertical plate and the right vertical plate. In the non-working state, a counterweight is supported above each of the two support parts. The support plate is located below the two counterweights, and the two counterweights can slide up and down along the left vertical plate and the right vertical plate respectively. When the support plate moves upward, it can abut against the two counterweights at the same time. The width dimension of the square ring is equal to the length of the long hole minus the diameter of the shaft.

[0014] Preferably, the upper extension plate is fixedly welded to the two side plates respectively.

[0015] Preferably, the lower extension plate is also provided with a long hole corresponding to the upper extension plate.

[0016] Preferably, a buffer pad is arranged on the upper surface of the support plate.

[0017] Preferably, the reel assembly includes two reels.

[0018] Preferably, a reel shaft is arranged between the two reels.

[0019] Preferably, a connecting shaft is arranged inside the reel shaft to connect the driving shaft.

[0020] Preferably, a groove is arranged on the outer surface of the reel shaft.

[0021] Preferably, after the cable is led out from the reel assembly, it directly enters the vertical roller group.

[0022] Preferably, the connecting frame includes two connecting plates.

[0023] The beneficial effects of the present invention are as follows:

[0024] First, for the first point proposed in the background art, the small-amplitude tension fluctuation of the cable is mainly adjusted by the spring adjustment guide frame. The load fluctuation of the cable is macroscopically manifested as the stretching of the cable, and the role of the spring adjustment guide frame is to convert the load fluctuation into the telescopic stress of the spring, thereby reducing the stretching degree of the cable. The general solution is to arrange a square ring part at the lower end of the spring rod, and the cable passes through the ring part.

[0025] Second, for the second point proposed in the background art, correspondingly, counterweights are arranged on the return path of the square ring, and a support plate is arranged at the lower end of the square ring. The support plate abuts against the counterweights when returning to increase the bearing weight when the spring returns quickly, so that the return of the spring becomes sluggish under the increased load, avoiding the impact of rapid return. In the normal state, the counterweights are supported by the support parts below, and can be further abutted by the support plate to be lifted along the slide rail.

[0026] III. Regarding the third point raised in the background art, a dual-module bracket is designed. The main bracket module is a vertical bracket, with a spring rod carried above it. The secondary bracket module includes a motor fixing frame and two extension plates. The motor fixing frame houses a driving roller group, and a vertical roller group is placed between the two extension plates. Due to the independence of the secondary bracket module, it can be assembled and then welded to the main bracket module, making the structure more compact and ensuring the convenience of assembly at the same time. There are through holes on the upper extension plate and the upper plate of the main bracket, and both through holes allow the spring rod to pass through, thereby achieving two-point stability maintenance for the spring rod.

[0027] IV. Regarding the fourth point raised in the background art, multiple technical solutions are adopted to solve the problem:

[0028] 1. The combination of the vertical roller group, the square ring, and the driving roller group provides a non-tilting cable direction. Specifically, the vertical roller group is used to constrain the cable in the horizontal direction. There are adjustment elongated holes on the extension plate to adjust the spacing of the vertical roller group to adapt to different cables. The width of the square ring is equal to the difference between the length of the adjustment elongated hole and the shaft diameter of a single vertical roller. After the cable passes through the vertical roller group and the square ring, it basically does not undergo angular deviation. The driving roller group provides further driving force at a position adjacent to the square ring. Thus, the three provide an overall unit to provide a cable direction that basically does not deviate.

[0029] 2. When there is an angular deviation between the reel end and the other end of the cable, since the above combination of the three is arranged on the dual-module bracket, there is a sliding table below the dual-module bracket, and the dual-module bracket can move along the sliding table to adapt to the angle between the cable and the reel end. At the same time, since the vertical roller group faces the reel end, the cable enters the middle of the vertical roller group and contacts cylindrical rollers. The cylindrical transition surface can better protect the cable from sharp scratches.

[0030] Based on the above two points, an intermediate calibration module is constructed to adapt to the angular deviation between the reel end and the other end.

[0031] Note: The above designs are not in a specific order, and each one makes the present invention different and significantly progressive compared to the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
