Description

Technical Field

[0001] The utility model relates to the technical field of umbilical cables, and particularly relates to an umbilical cable winch. Background Technique

[0002] An umbilical cable is a combination of a cable (power cable or signal cable), an optical fiber cable (single-mode or multi-mode optical fiber cable), a hydraulic or chemical agent pipe (steel pipe or hose), and is mainly used for deep-water oil and gas exploration and development, such as the transmission of electricity, signals, and data between the seabed and the DPP, as well as the transportation of chemical agents and liquids.

[0003] A winch is a machine that can wind ropes under power drive. The umbilical cable also needs to be wound around the outside of the winch for storage, payed out when in use, and rewound after use. However, the existing umbilical cable winch has no fixing structure and cannot fix the winding disk. When pulling the umbilical cable, the winding disk will be driven to rotate. Therefore, an umbilical cable winch is proposed. The compression spring pushes the iron column upward, and its top end is inserted into the card slot, and the shaft rod is fixed through the shaft sleeve, so as to fix the winding disk and prevent it from rotating. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides an umbilical cable winch. The compression spring pushes the iron column upward, and its top end is inserted into the card slot, and the shaft rod is fixed through the shaft sleeve, so as to fix the winding disk and prevent it from rotating.

[0005] The technical solution adopted by the utility model to solve its technical problems is an umbilical cable winch, which includes a shaft rod rotatably connected to the inside of a base through a bearing. A winding disk is fixedly sleeved on the outside of the shaft rod through bolts. A shaft sleeve is fixedly sleeved on the outside of one end of the shaft rod located at the winding disk through a flat key. Card slots are equidistantly arranged on the outside of the shaft sleeve. A large gear is fixedly sleeved on the outside of the shaft rod between the shaft sleeve and the winding disk through a flat key. A reduction motor is installed at the inner bottom of the base through a mounting frame, and a protective cover is fixedly installed on one side of the base through bolts;

[0006] A clamping and fixing assembly is arranged at the bottom of the protective cover. The clamping and fixing assembly includes a glass fiber sheath connected to the bottom of the protective cover through a threaded groove. An iron sleeve is fixedly sleeved inside the glass fiber sheath. An electromagnetic coil is sleeved on the outside of the iron sleeve. An iron column is sleeved inside the iron sleeve. A compression spring is fixedly installed at the bottom of the iron column located inside the iron sleeve through a bolt.

[0007] By adopting the above technical solution, the reduction motor drives the shaft rod and the winding disk outside it to rotate forward and backward for rewinding and paying out. The compression spring pushes the iron column upward, and the shaft rod and the winding disk outside it are fixed through the shaft sleeve. After the electromagnetic coil is energized, the iron sleeve generates magnetism and adsorbs the iron column into its interior, so as not to affect the rotation of the shaft rod.

[0008] Specifically, a moving component is provided on the top of the base. The moving component includes a gantry fixed to the top of the base by bolts. A driving motor is installed on one side of the gantry through a mounting frame, and a reciprocating lead screw is rotatably connected inside the gantry through bearings.

[0009] Specifically, an internally threaded slider is sleeved on the outside of the reciprocating lead screw, and a wire sleeve is fixed to the bottom of the reciprocating lead screw by bolts.

[0010] Specifically, an auxiliary rod is fixed to the inside of the gantry at the top of the reciprocating lead screw by bolts, and the auxiliary rod penetrates through the internally threaded slider.

[0011] Specifically, the bushing is located inside the protective cover, and the fiberglass sheath is communicated with the protective cover.

[0012] Specifically, a small gear is fixedly sleeved on the output shaft on one side of the reduction motor through a flat key, and the small gear meshes with a large gear.

[0013] Advantages of the present utility model:

[0014] For the umbilical cable winch of the present utility model, the compression spring pushes the iron column upward, so that the top of the iron column is inserted into the corresponding card slot, and the shaft rod and the winding disc on its outside are fixed through the bushing, preventing the winding disc from rotating when pulling the umbilical cable. When the reduction motor works, the electromagnetic coil is powered, and after the electromagnetic coil is energized, the iron sleeve generates magnetism and adsorbs the iron column into it, without affecting the rotation of the shaft rod.

[0015] For the umbilical cable winch of the present utility model, when taking up the line, the driving motor is turned on to drive the reciprocating lead screw to rotate. The reciprocating lead screw rotates to push the internally threaded slider and the wire sleeve at its bottom to reciprocate. When the wire sleeve reciprocates, it can drive the umbilical cable to move, and when taking up the line, the umbilical cable can be evenly wound around the outside of the winding disc.

The compression spring 405 pushes the iron column 404 upward to fix the shaft rod 2 and the winding disc 6 outside it through the shaft sleeve 9. After the electromagnetic coil 403 is energized, the iron sleeve 402 generates magnetism and adsorbs the iron column 404 into its interior, so as not to affect the rotation of the shaft rod 2.

[0027] Exemplarily, as Figure 5As shown, the utility model further includes. A moving component 5 is arranged on the top of the base 1. The moving component 5 includes a gantry 501 fixed to the top of the base 1 by bolts. A driving motor 505 is installed on one side of the gantry 501 through a mounting frame. A reciprocating lead screw 502 is rotatably connected to the inside of the gantry 501 through bearings.

[0028] When in use, the driving motor 505 is used to drive the reciprocating lead screw 502 to rotate.

[0029] Exemplarily, as Figure 5 As shown, the utility model further includes. An internally threaded slider 503 is sleeved on the outside of the reciprocating lead screw 502. A wire sleeve 504 is fixed to the bottom of the reciprocating lead screw 502 by bolts.

[0038] Open the winding disc 6. The pinion 11 and the large gear 8 drive the shaft rod 2 and the winding disc 6 outside it to rotate. The winding disc 6 rotates forward to pay out the wire, and the winding disc 6 rotates in reverse to take up the wire;

[0039] When taking up the wire, turn on the driving motor 505 to drive the reciprocating lead screw 502 to rotate. The reciprocating lead screw 502 rotates to push the internally threaded slider 503 and the wire sleeve 504 at its bottom to move reciprocally. When the wire sleeve 504 moves reciprocally, it can drive the umbilical cable to move. When taking up the wire, the umbilical cable can be evenly wound around the outside of the winding disc 6;

[0040] The compression spring 405 pushes the iron column 404 upward, so that the top of the iron column 404 is inserted into the corresponding card slot 10, and the shaft rod 2 and the winding disc 6 outside it are fixed through the shaft sleeve 9 to prevent the winding disc 6 from rotating when pulling the umbilical cable. When the reduction motor 7 works, power is supplied to the electromagnetic coil 403.
