Description

Technical Field

[0001] This invention relates to the field of cable winding and unwinding control, and more specifically to a manual braking winding system. Background Technology

[0002] With my country's modernization, further exploration of marine resources, development of urban subways, and increasing depth of oil and gas energy extraction, there is a growing demand for long-distance wired communication in deep-sea wells, underground tunnel construction, and for specialized robots. As a result, cable reels are becoming increasingly longer. To ensure reliable communication, a stable long-distance transmission method is needed, and cable reels are the primary equipment used to ensure the normal operation of long-distance wired communication for machines.

[0003] In practical engineering work, the following problems exist:

[0004] I. Existing electric cable winding and unwinding systems do not pay attention to changes in cable tension. The tension during winding and unwinding is easily too high or too low. Excessive tension can lead to overall cable deformation and surface wrinkling, while insufficient tension can cause loose winding and prevent proper winding and unwinding. For example, when winding the cable, the winding radius on the reel gradually increases. If the motor speed of the cable winding and unwinding reel is constant, the winding speed of the cable at the beginning of winding on the reel will gradually increase, while the working load and speed changes of the cable at the other end are unknown, potentially causing tension fluctuations. To control the tension on the cable rope, there are generally two approaches: one is to control the speed difference before and after winding and unwinding, and the other is to control the output torque of the cable reel motor. However, both of these solutions require servo feedback technology, which is a precision technology with high cost and short service life.

[0005] Second, the solution in point one above utilizes spring force to reduce tension fluctuations and provides tension compensation. However, there are still areas for improvement in actual use: when the cable initially acts on the spring under tension, the force is linear, resulting in a smooth transition and stable action. However, the spring rebounds with a larger and faster action, still causing some tension fluctuations, which can affect the cable itself and its collisions with other components.

[0006] Third, in the existing technology, auxiliary control equipment for cables, such as rollers, is often a separate support structure. The larger number of parts requires multiple support structures, which leads to a significant increase in manpower and material resources in the procurement, transportation, and assembly processes.

[0007] Fourth, in the existing cable winding and unwinding process, there is often a certain distance between the cable reel end and the other end of the cable, making precise alignment difficult. Inaccurate alignment may cause cable deviation, and solutions may require more expensive and precise instruments. Summary of the Invention

[0008] To overcome the above problems, the present invention proposes a solution that addresses multiple problems simultaneously.

[0009] The technical solution adopted by this invention to solve its technical problem is: a manual braking winding system, including a drive device, a drum assembly, a braking module, a connecting frame, a base frame, a slide table, and a cable control module. The drum assembly includes two reels, with a spool between the two reels. A cable is wound on the spool. The drive device drives the drum assembly to rotate. One end of the spool extends out of the reel to form an extension. The braking module includes a brake band, a first rod, a second rod, a support rod, a main rod, a first support, a second support, a third support, a third rod, and a connecting rod. The brake band is wound on the extension. The main rod is pivotally connected to the first support, the support rod is pivotally connected to the second support, and the connecting rod is pivotally connected to the third support. The upper end of the connecting rod is connected to one end of the brake band, and the other end of the brake band is connected to one end of the first rod. The other end of the first rod is pivotally connected to one end of the third rod, and the other end of the third rod is pivotally connected to the support rod. The upper end of the support rod is pivotally connected to one end of the second rod, and the other end of the second rod is pivotally connected to the main rod.

[0010] The cable control module includes a main support module, a secondary support module, a spring adjustment module, a drive roller group, and a vertical roller group. The main support module includes an upper plate, two side plates, and a bottom plate. The secondary support module includes a frame, 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 part, and a counterweight.

[0011] The reel assembly is fixed to the base frame, and one end of the connecting frame is also fixed to the base frame. The connecting frame is inclined, and the other end of the connecting frame is connected to the slide table. The main support module is set above the slide table, and the main support module can move along the slide table. Two side plates are set above the base plate, and the upper ends of the two side plates are connected by the upper plate. The upper plate has a first through hole. An upper extension plate and a lower extension plate are fixed to the frame, and the upper extension plate and the lower extension plate are both fixed between the two side plates. A second through hole is opened on the upper extension plate, and the spring rod passes through the first through hole and the second through hole. The spring is sleeved on the spring rod, and a top plate is fixed to the upper end of the spring rod. The upper end of the spring abuts against the top plate, and the lower end abuts against the upper plate.

[0012] The frame is provided with a horizontally arranged drive roller group, and a vertical roller group is provided between the upper extension plate and the lower extension plate; an elongated hole is provided on the upper extension plate to adjust the distance between the two rollers of the vertical roller group, and the shaft of one roller in the vertical roller group is accommodated in the elongated hole.

[0013] The lower surface of the upper extension plate is connected to a left vertical plate and a right vertical plate. The lower end of the spring rod is connected to a square ring, and the lower end of the square ring is connected to the support plate. The lower ends of the left and right vertical plates are each provided with a support portion. In the non-working state, each of the two support portions supports a counterweight. The support plate is located below the two counterweights, and the two counterweights can slide up and down along the left and right vertical plates respectively. When the support plate moves upward, it can simultaneously abut against the two counterweights. The width of the square ring is equal to the length of the elongated hole minus the diameter of the shaft.

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

[0015] Preferably, the lower extension plate also has an elongated hole corresponding to the upper extension plate.

[0016] Preferably, a cushioning pad is provided on the upper surface of the pallet.

[0017] Preferably, it also includes a support frame.

[0018] Preferably, the upright frame is equipped with a pulley system.

[0019] Preferably, the scroll has a connecting shaft inside.

[0020] Preferably, the outer surface of the reel is provided with a groove.

[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 this invention are:

[0024] I. Regarding the first point raised in the background technology, the small-amplitude tension fluctuation of the cable is mainly regulated by the spring-adjustable guide frame. The load fluctuation of the cable is macroscopically manifested as the cable tension, and the function of the spring-adjustable guide frame is to convert the load fluctuation into the spring's expansion and contraction stress, thereby reducing the degree of cable tension; the general solution is to set a square ring at the lower end of the spring rod, and the cable can pass through the ring.

[0025] Second, in response to the second point raised in the background technology, a counterweight is set on the return path of the square ring, and a support plate is set at the lower end of the square ring. When the ring returns, the support plate abuts against the counterweight to increase the load-bearing weight when the spring returns quickly. Thus, under the increased load, the return of the spring becomes slower, avoiding the impact of rapid return. Under normal conditions, the counterweight is supported by the support part below and can be further abutted by the support plate to be lifted along the slide rail.

[0026] Thirdly, in response to the third point raised in the background technology, a dual-module support is designed. The main support module is a vertical support with a spring rod on top. The secondary support module includes a motor fixing frame and two extension plates. The motor fixing frame houses the drive roller assembly, and the vertical roller assembly is placed between the two extension plates. Due to the independence of the secondary support module, it can be assembled and then welded to the main support module, thus making the structure more compact and ensuring ease of assembly. The upper extension plate has through holes, and the upper plate of the main support has through holes. Both through holes allow the spring rod to pass through, thereby maintaining the stability of the spring rod at two points.

[0027] Fourthly, regarding the fourth point raised in the background technology, multiple technical solutions are adopted to address the problem:

[0028] (i) The combination of vertical rollers, square rings, and drive rollers provides a non-tilting cable orientation. Specifically, the vertical rollers constrain the cable horizontally. An adjustment hole on the extension plate allows for adjusting the spacing of the vertical rollers to accommodate different cables. The width of the square ring is equal to the difference between the length of the adjustment hole and the shaft diameter of a single vertical roller. After passing through the vertical rollers and square rings, the cable exhibits minimal angular deviation. The drive rollers provide further driving force near the square rings. Thus, these three components form a unified unit providing a virtually non-tilting cable orientation.

[0029] (ii) When there is an angular offset between the reel end and the other end of the cable, since the combination of the above three is set on the double module bracket, and there is a slide table under the double module bracket, the double module bracket can move along the slide 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 the cylindrical roller. The cylindrical transition surface can better protect the cable from sharp scratches.

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

[0031] Note: The above designs are not in any particular order, and each one makes the present invention different from the prior art and a significant advancement. Attached Figure Description
