Description

Technical Field

[0001] The utility model belongs to the technical field of deep - sea operation instruments, and particularly relates to an umbilical cable winch for deep - sea operation. Background Technique

[0002] An umbilical cable is a multi - functional cable designed specifically for underwater production systems. Its main functions include providing power for underwater production systems, controlling hydraulic channels, transporting chemical agents, and transmitting control signals and sensor data. This cable can withstand extreme conditions such as high pressure, high salinity, and low temperature in the deep - sea environment, and at the same time has good seawater corrosion resistance and abrasion resistance.

[0003] When the existing umbilical cable winch for deep - sea operation is winding up, only a certain amount of umbilical cable can be wound on the surface of a drum. Since the distance between the side plates at both ends of the drum is fixed and cannot be changed arbitrarily, it is not convenient to disassemble the drum between the reducer and the umbilical cable slip ring for replacement. Therefore, improvements are needed. Content of the Utility Model

[0004] In order to overcome the above - mentioned defects, the utility model provides an umbilical cable winch for deep - sea operation, which solves the problem that when the existing umbilical cable winch for deep - sea operation is winding up, since the distance between the side plates at both ends of the drum is fixed and cannot be changed arbitrarily, it is not convenient to disassemble the drum between the reducer and the umbilical cable slip ring for replacement.

[0005] To achieve the above object, the utility model provides the following technical solution: An umbilical cable winch for deep - sea operation, including a fixed bottom plate. On both sides inside the fixed bottom plate, two groups of installation grooves are symmetrically arranged respectively. On both sides of the inner wall of the installation groove, limiting sliding grooves one are symmetrically arranged. At the central position inside the fixed bottom plate, an electric push rod is fixedly installed. One end of the electric push rod extends out of the fixed bottom plate and is fixedly installed with an end block. At the central position on one side of the fixed bottom plate where the end block is located, a concave - shaped frame is fixedly installed.

[0006] On both sides of the end block, mounting frames are symmetrically and fixedly installed. On one side of the top of the fixed bottom plate, a cable arranging device is fixedly installed. On the side of the top of the fixed bottom plate far from the mounting frame, a side plate one is fixedly installed. On the side of the top of the mounting frame far from the fixed bottom plate, a side plate two is fixedly installed, and the positions of the side plate one and the side plate two correspond to each other. On the side of the side plate one and the side plate two far from the cable arranging device, there is a mounting plate.

[0007] As a further solution of the utility model: On the top and bottom of the end block, moving rollers are symmetrically and fixedly installed. On the top and bottom of the concave - shaped frame, limiting sliding grooves two are symmetrically arranged, and the positions of the limiting sliding grooves two correspond to those of the moving rollers.

[0008] As a further solution of the utility model: three mounting shafts are fixedly installed at the inner bottom of the mounting frame, and moving rollers are rotatably installed on the surfaces of the mounting shafts. Two limiting slide bars are symmetrically and fixedly installed on the surface of the mounting frame close to one side of the fixed bottom plate.

[0009] As a further solution of the utility model: the positions of the limiting slide bars correspond to those of the mounting grooves. At the ends of the limiting slide bars inserted into the interior of the mounting grooves, limiting rollers are symmetrically and fixedly installed, and the positions of the limiting rollers correspond to those of the first limiting sliding grooves.

[0010] As a further solution of the utility model: a hydraulic motor is provided at the central position of the top of the first side plate, and a speed reducer is provided on one side of the hydraulic motor and located at the first side plate. A umbilical cable slip ring is provided at the central position of the top of the second side plate. The position of the umbilical cable slip ring corresponds to those of the hydraulic motor and the speed reducer. A winding drum is provided on the surface between the first side plate and the second side plate where the speed reducer and the umbilical cable slip ring are located.

[0011] As a further solution of the utility model: a pressing plate is rotatably installed at the top end of the mounting plate. Compression springs are symmetrically provided between the central positions of the mounting plate and the pressing plate. Pressing rollers are symmetrically and rotatably installed on the side of the pressing plate away from the mounting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For the umbilical cable winch for deep-sea operations, by setting the fixed bottom plate, mounting frame, electric push rod, limiting slide bar and limiting roller, when the electric push rod is controlled to extend, the end block drives the two mounting frames to move away from the fixed bottom plate, thereby driving the second side plate away from the first side plate, which is convenient for disassembling and replacing the winding drum between the first side plate and the second side plate. At the same time, when the mounting frame is controlled to approach or move away from the fixed bottom plate, the limiting slide bar is driven to slide inside the mounting groove, so that the limiting roller slides inside the corresponding first limiting sliding groove, thereby ensuring that the mounting frame will not deflect when moving away from or approaching the fixed bottom plate, and preventing misalignment and deflection between the first side plate and the second side plate.

[0014] 2. For the umbilical cable winch for deep-sea operations, by setting the winding drum, pressing plate, compression spring and pressing roller, the pressing plate is rotated on the top of the mounting plate, which is convenient for fixing the winding drum between the first side plate and the second side plate. When the pressing plate is loosened, the two pressing rollers at the end of the pressing plate away from the mounting plate are pressed against the surface of the winding drum under the elastic return of the compression spring. When the hydraulic motor is started to drive the winding drum to wind the cable, the cable wound on the surface of the winding drum is pressed against the surface of the winding drum by the pressing roller, ensuring that the cable will not be scattered when being wound on the surface of the winding drum.

Specific embodiments

[0019] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0020] As Figures 1-3 shown, the present utility model provides a technical solution: an umbilical cable winch for deep-sea operations, including a fixed bottom plate 1. On both sides inside the fixed bottom plate 1, two groups of mounting grooves 2 are symmetrically arranged respectively. On both sides of the inner wall of the mounting groove 2, first limiting sliding grooves 3 are symmetrically arranged. At the central position inside the fixed bottom plate 1, an electric push rod 4 is fixedly installed. By providing the electric push rod 4 and controlling the telescopic movement of the electric push rod 4, the end block 5 drives the two mounting frames 9 to move synchronously closer to or away from the fixed bottom plate 1, thereby controlling the distance between the first side plate 14 and the second side plate 16, facilitating the removal and replacement of the reel 20 between the first side plate 14 and the second side plate 16;

[0021] At one end where the electric push rod 4 extends out of the fixed bottom plate 1, an end block 5 is fixedly installed. At the top and bottom of the end block 5, moving rollers 6 are symmetrically and fixedly installed. At the central position on one side of the fixed bottom plate 1 where the end block 5 is located, a concave-shaped frame 7 is fixedly installed; on the top and bottom of the concave-shaped frame 7, second limiting sliding grooves 8 are symmetrically arranged, and the positions of the second limiting sliding grooves 8 correspond to those of the moving rollers 6. Due to the provision of the moving rollers 6 and the second limiting sliding grooves 8, when the electric push rod 4 controls the end block 5 to move inside the concave-shaped frame 7, the moving rollers 6 move inside the corresponding second limiting sliding grooves 8, thereby ensuring that the end block 5 does not tilt or deflect during the movement.

[0022] On both sides of the end block 5, mounting brackets 9 are symmetrically and fixedly installed. At the inner bottom of the mounting bracket 9, three mounting shafts 10 are fixedly installed, and a moving roller 11 is rotatably installed on the surface of the mounting shaft 10. On the surface of the mounting bracket 9 close to one side of the fixed base plate 1, two limiting slide bars 12 are symmetrically and fixedly installed. By providing the moving roller 11, when controlling the end block 5 to drive the two mounting brackets 9 to move on the ground, the moving roller 11 rolls by friction with the ground, thereby reducing the friction when the mounting bracket 9 moves on the ground.

[0023] The positions of the limiting slide bars 12 correspond to those of the mounting grooves 2. At the ends of the limiting slide bars 12 inserted into the interior of the mounting grooves 2, limiting rollers 13 are symmetrically and fixedly installed, and the positions of the limiting rollers 13 correspond to those of the first limiting chute 3. Due to the provision of the first limiting chute 3 and the limiting rollers 13, when controlling the mounting bracket 9 to approach or move away from the fixed base plate 1, the limiting slide bars 12 are driven to move inside the mounting grooves 2, causing the limiting rollers 13 to move inside the corresponding first limiting chute 3, thereby ensuring that the mounting bracket 9 will not tilt or deflect during the movement, and at the same time restricting the distance of the mounting bracket 9 away from the fixed base plate 1.

[0024] On one side of the top of the fixed base plate 1, a cable arranging device 15 is fixedly installed. On the side of the top of the fixed base plate 1 away from the mounting bracket 9, a first side plate 14 is fixedly installed. On the side of the top of the mounting bracket 9 away from the fixed base plate 1, a second side plate 16 is fixedly installed, and the positions of the first side plate 14 and the second side plate 16 correspond to each other. At the central position of the top of the first side plate 14, a hydraulic motor 17 is provided, and a speed reducer 18 is provided on one side of the hydraulic motor 17. At the central position of the top of the second side plate 16, an umbilical cable slip ring 19 is provided, and the positions of the umbilical cable slip ring 19, the hydraulic motor 17, and the speed reducer 18 correspond to each other. On the surface between the first side plate 14 and the second side plate 16, a winding drum 20 is provided between the speed reducer 18 and the umbilical cable slip ring 19. By providing the hydraulic motor 17, after clamping and fixing the winding drum 20 on the surfaces of the speed reducer 18 and the umbilical cable slip ring 19 between the first side plate 14 and the second side plate 16, the hydraulic motor 17 is started to drive the winding drum 20 to rotate, thereby winding the cable.

[0025] On the side of the first side plate 14 and the second side plate 16 away from the cable arranging device 15, a mounting plate 21 is provided. At the top of the mounting plate 21, a pressing plate 22 is rotatably installed. Between the central positions of the mounting plate 21 and the pressing plate 22, pressing springs 23 are symmetrically provided. On the side of the pressing plate 22 away from the mounting plate 21, pressing rollers 24 are symmetrically and rotatably installed. Due to the provision of the pressing springs 23, under the rebounding action of the pressing springs 23, the pressing plate 22 is pulled towards the mounting plate 21, causing the pressing rollers 24 to press against the surface of the winding drum 20, thereby pressing the cable against the surface of the winding drum 20 to ensure that the cable will not become loose when being wound on the surface of the winding drum 20.

[0026] The working principle of the present utility model is as follows:

[0027] Place the fixed base plate 1 and the mounting frame 9 on the plane at the designated position. Control the electric push rod 4 to extend, push the end block 5 away from the fixed base plate 1, drive the two groups of mounting frames 9 away from the fixed base plate 1, pull out the limit slide rod 12 from the inside of the mounting groove 2, and at the same time move the roller 11 to roll frictionally on the plane, so that the second side plate 16 moves away from the first side plate 14 until the distance between the mounting frame 9 and the fixed base plate 1 allows the reel 20 to be placed between the first side plate 14 and the second side plate 16. Place the reel 20 corresponding to the reducer 18 and the umbilical cable slip ring 19 between the first side plate 14 and the second side plate 16. Control the electric push rod 4 to contract, drive the end block 5 to move towards the fixed base plate 1 until the two groups of mounting frames 9 are tightly attached to one side of the fixed base plate 1. Start the hydraulic motor 17 to control the reel 20 to rotate and wind the cable. When the cable on the surface of the reel 20 gradually thickens, under the rebounding action of the compression spring 23, press the pressing plate 22 towards the mounting plate 21 to ensure that the cable pressing roller 24 is tightly attached to the surface of the cable, press the cable tightly on the surface of the reel 20 and wind the cable.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0029] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the purpose of this patent.
