Description

Technical Field

[0001] The invention belongs to the technical field of ship deck machinery, and in particular relates to a self-locking control device for a submarine photoelectric composite cable winch. Background Art

[0002] The submarine optoelectronic composite cable winch is an important equipment for completing the lifting and lowering of ocean detection instruments. The performance of the winch is one of the main equipment that determines the detection efficiency and whether the detection task can be successfully completed. After investigating my country's drilling platforms, it was found that the brake system used in the submarine optoelectronic composite cable winch adopts a belt brake. The belt brake is a lever-type semi-enclosed brake hub brake device, that is, the brake handle controls the brake band to surround and fit the brake. The advantages of this type of brake are: simple structural design, easy processing and manufacturing, low maintenance cost, and no need for precision components. However, due to structural design problems, operators need to work in the open air for a long time, with great labor intensity and physical exertion. Due to the problem of fitting the brake hub and the brake band, the brake inertia distance is large and the reliability is poor. Under long-term use, the contact between the brake band and the brake hub produces thermal expansion, resulting in poor brake reliability.

[0003] With the development of petroleum technology, the automation level of equipment has been greatly improved. Some submarine optical fiber composite cable winches are also equipped with hydraulic disc brakes. The advantage is that the hydraulic disc brake is integrated with other control systems and parameter instruments for on-site operations to form a modular control operation. At the same time, it improves the working environment of the operator and reduces the labor intensity of the operator. However, it is necessary to equip a special hydraulic station and special hydraulic oil, which has high equipment investment and maintenance costs, and increases the risk of environmental pollution after hydraulic oil leakage. At the same time, if the hydraulic pressure is lost or the valve does not move, it will cause brake failure or brake failure. In addition, since the gap between the friction plate and the brake disc of the hydraulic disc brake is relatively high, the gap adjustment parameters require relatively precise adjustment. If the gap is improperly adjusted or the hydraulic disc brake working caliper is a spring-supported hydraulic brake block, the long-term use of the spring will cause the spring to fail. The safety clamp is a disc spring structure, and the disc spring needs to be replaced regularly. If the braking torque is affected by the friction plate gap or there is an error in the adjustment of the friction plate gap, the braking torque will be reduced, causing braking time delay and increased braking distance. If the hydraulic oil has poor fluidity at low temperatures in winter, it will also cause a decrease in braking performance. In short, hydraulic disc brakes have relatively high requirements for working conditions, maintenance technology, and component performance.

[0004] Some submarine optical fiber composite cable winches have brake devices placed between the motor and the reducer, and use reverse braking or energy consumption braking to achieve braking of the submarine optical fiber composite cable winch. However, this type of braking has limited braking torque. Due to the existence of load inertia, it will continue to rotate for a period of time, and the submarine optical fiber composite cable winch cannot be parked at a fixed point. It is easy to tear off this "delicate" optical fiber composite cable, resulting in the inability to carry out normal marine exploration work. Summary of the invention

[0005] The purpose of the present invention is to provide a self-locking control device for a submarine photoelectric composite cable winch, which solves the problems that the existing winches are difficult to park at a fixed point, the labor intensity and physical exertion are high when using belt brakes, and the use of disc brakes requires a special hydraulic station and special hydraulic oil.

[0034] Example 2

[0035] The adjusting hand wheel 4 comprises a base 4-6, on which a horizontal transmission shaft 4-7 is rotatably connected, one end of the transmission shaft 4-7 is sleeved with a transition sprocket I 4-2 connected to the drive assembly 3 chain in a clearance fit, one side of the transition sprocket I 4-2 is connected to a handle 4-1 sleeved on the transmission shaft 4-7 and keyed thereto through a clutch mechanism, and the other end of the transmission shaft 4-7 is sleeved with a transition sprocket II 4-5 connected to the drive sprocket 6 chain in a fixed manner. The clutch mechanism comprises meshing teeth I 4-3 and meshing teeth II 4-4 respectively fixed on opposite sides of the handle 4-1 and the transition sprocket I 4-2, and both the meshing teeth I 4-3 and the meshing teeth II 4-4 are annular in shape coaxial with the transmission shaft 4-7 and have mutually meshing teeth on opposite sides.

[0036] The self-locking disc brake 5 includes a disc-shaped fixing ring Ⅰ5-8 and a fixing ring Ⅱ5-10 whose openings are opposite to each other and fixed to each other. The end faces of the fixing ring Ⅰ5-8 and the fixing ring Ⅱ5-10 are provided with corresponding assembly holes 5-9 spaced apart along the circumferential direction. The two relative assembly holes 5-9 are connected by fastening bolts 5-11 for easy installation and disassembly. A through hole is commonly opened in the center of the fixing ring Ⅰ5-8 and the fixing ring Ⅱ5-10 along the axial direction, and a support ring 5-12 is coaxially arranged in the through hole, one end of the support ring 5-12 extends outward and is fixed to the main frame 1, and four groups of arc-shaped teeth 5-1 are evenly fixed on the inner end wall of the fixing ring Ⅱ5-10. The arc-shaped teeth 5-1 include an arc segment body with the same arc direction as the side wall of the fixing ring Ⅱ5-10, and the side wall of the arc segment body is circumferentially provided with teeth, the outer side of the arc segment body is a release section 5-1-2, and the outer side is a locking section 5-1-1, and the two ends of the arc segment body are transition section Ⅰ5-1-3 and transition section Ⅱ5-1-4 respectively, and the arc lengths are equal. The outer side wall of the fixed ring II 5-10 is circumferentially provided with incomplete teeth 5-13 meshing with the driving sprocket 6, and the teeth of the incomplete teeth 5-13 are arranged on the outer side wall of the fixed ring II 5-10 between each two adjacent groups of arc-shaped teeth 5-1; the inner end wall of the fixed ring I 5-8 is provided with four groups of interconnected arc-shaped guide grooves 5-5 corresponding to the four groups of arc-shaped teeth 5-1, and two adjacent groups of arc-shaped guide grooves 5-5 are respectively opened corresponding to the locking sections 5-1-1 and the release sections 5-1-2 of the two adjacent groups of arc-shaped teeth 5-1. The inner end wall of the fixed ring I 5-8 is fixedly provided with a gap adjustment platform 5-1-6 located on one side of the arc-shaped guide groove 5-5, facing each group of arc-shaped teeth 5-1. The gap adjustment platform 5-1-6 and the arc-shaped teeth 5-1 are radially provided with gap adjustment holes 5-1-5. By changing the radial fixed position of the arc-shaped teeth 5-1 and the gap adjustment platform 5-1-6, it is used to compensate for the problem of brake failure caused by excessive brake clearance after the brake pad is worn. The positions on the opposite sides of the fixed ring I 5-8 in the arc-shaped guide groove 5-5 are each matched with a T-shaped rod with another horizontal section extending into the fixed ring II 5-10. The vertical section of each T-shaped rod is radially penetrated inward along the support ring 5-12 and is fixedly connected with a movable locking block 5-7 that can reach the side wall of the main shaft 7.

[0037] The T-shaped rod in the self-locking disc brake 5 includes a connecting rod Ⅰ5-3, one end of which is sleeved with an adjusting wheel 5-4 located in an arc-shaped guide groove 5-5, the other end of which is sleeved with a small gear 5-2 that can mesh with the arc-shaped teeth 5-1, and one side of the connecting rod Ⅰ5-3 is vertically fixedly connected to a connecting rod Ⅱ5-6 whose other end is connected to a movable locking block 5-7.

The maximum displacement of the two wedge blocks 5-7-2 to move outward is within the inner ring range of the support ring 5-12, and the two wedge blocks 5-7-2 always slide in the U-shaped seat 5-7-1. In order to increase the braking effect of the self-locking disc brake 5, the two wedge blocks 5-7-2 are close to each other on the side to form a V-shaped interval and stripe grooves are provided on the side walls close to each other. Corresponding stripe grooves can also be added on the outer surface of the main shaft 7. A clamping spring 5-7-3 is fixedly connected between the ends of the two wedge blocks 5-7-2.

[0039] Example 3

[0040] The self-locking control method of the submarine photoelectric composite cable winch of the present invention is as follows: the driving assembly 3 drives the winch drum 2 to rotate forward or reversely to realize the recovery and lowering of the cable, and at the same time, the driving assembly 3 drives the transition sprocket I4-2 to rotate on the transmission shaft 4-7. When braking, the handle 4-1 is pushed inward along the transmission shaft 4-7, so that the meshing teeth I4-3 and the meshing teeth II4-4 are meshed. Since the handle 4-1 is key-connected to the transmission shaft 4-7, the rotation of the transition sprocket I4-2 after meshing can drive the handle 4-1 and the transmission shaft 4-7 to rotate at the same time, thereby driving the transition sprocket II4-5 on the other side of the base 4-6 to rotate, and then driving the driving sprocket 6 to rotate through the longitudinal chain 8. The driving sprocket 6 drives the fixed ring II5-10 to rotate through the meshing incomplete teeth 5-13, so that the meshing arc teeth 5-1 of the pinion 5-2 are turned from the release section 5-1-2 to the next locking section 5-1-1. In this process, Since the support ring 5-12 is in a fixed state, the T-shaped rod is restricted in the circumferential direction and does not rotate with the fixed ring II 5-10. Instead, its connecting rod II 5-6 extends further into the support ring 5-12 due to the change in the radial position of the two adjacent arc-shaped teeth 5-1. During the movement of the T-shaped rod, the adjusting wheel 5-4 at the other end of the connecting rod I 5-3 limits the moving position of the T-shaped rod according to the path of the arc-shaped guide groove 5-5. After the connecting rod II 5-6 extends into the support ring 5-12, the U-shaped seat 5-7-1 of the movable locking block 5-7 connected thereto extends inward at the same time, and the four wedge blocks 5-7-2 on the two movable locking blocks 5-7 clamp the main shaft 7 from all sides. In the above process, when the driving sprocket 6 drives the fixing ring II 5-10 to rotate to the locking section 5-1-1 where the T-shaped rod is located at the arc-shaped tooth 5-1, the driving sprocket 6 also disengages the teeth of the incomplete teeth 5-13 and is located at the toothless section of the incomplete teeth 5-13. At this time, the self-locking disc brake 5 remains locked, that is, even if the self-locking disc brake 5 vibrates slightly, since the arc length direction of the locking section 5-1-1 is the same arc, it will not affect the clamping force of the movable locking block 5-7 and the locking state of the self-locking disc brake 5. Even if the operator makes a mistake in the control console, the self-locking disc brake 5 will not be unlocked naturally. When unlocking is required, pull out the handle 4-1 to separate the meshing teeth I 4-3 and the meshing teeth II 4-4, manually move the fixing ring II 5-10 to make the driving sprocket 6 mesh with the teeth of the incomplete teeth 5-13, and re-engage the clutch mechanism by driving the fixing ring II 5-10 to rotate with the help of the power of the driving assembly 3 to enter the unlocking state based on the above-mentioned similar principle. In the above process, changing the unlocking or parking state only requires slightly moving the fixing ring II 5-10, which reduces the labor intensity.

[0041] Through the above-mentioned manner, the self-locking control device for the submarine optoelectronic composite cable winch of the present invention arranges the self-locking disc brake 5 circumferentially on the driving main shaft 7 of the winch drum 2, and several wedge blocks 5-7-2 on the movable locking block 5-7 extending from the self-locking disc brake 5 fit with the main shaft 7, thereby increasing the fitting area and friction force, making the braking torque larger, achieving fixed-point parking, and improving the reliability and safety of braking; at the same time, the self-locking disc brake 5 can be unlocked or parked with the help of the drive assembly 3, overcoming the problems of belt brakes, high labor intensity and physical exertion, and the need to be equipped with a special hydraulic station and special hydraulic oil when using disc brakes.
