Description

Technical Field

[0001] This utility model relates to the field of cable installation equipment technology, and in particular to a winch for underground cable installation. Background Technology

[0002] Most of the crude oil in my country's deep-sea oil wells is heavy oil, which needs to be heated before it can be extracted. During the installation of equipment, heating cables need to be installed, with the total length of these cables reaching hundreds or even thousands of meters. To prevent the cables from breaking under their own weight, they need to be installed in sections, and the cable laying needs to be paused at each end for installing mounting brackets or connectors. Therefore, the winch needs to be able to release the cable at a uniform speed and stop quickly. Due to the significant weight of the cable, the stability requirements for the winch's braking and cable laying mechanisms are very high.

[0003] In the prior art, the utility model patent with authorization announcement number CN221370341U provides a winch brake device, relating to the field of marine winch technology. It includes two support plates and further comprises: a rotating shaft rotatably mounted on the two support plates; a winch roller fixedly mounted on the circumferential surface of the rotating shaft; a drive assembly mounted on the two support plates, the drive assembly receiving a drive source to rotate the winch roller; and a locking assembly mounted on one of the support plates, the locking assembly used to restrict the rotation of the winch roller. This utility model provides a winch brake device that, by utilizing the locking assembly, locks the cable after it has been wound or unwound to a certain extent, thereby restricting the rotation of the winch roller and minimizing the possibility of the cable unwinding from the winch roller due to the ship's swaying.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: 1. The patented technology uses a locking mechanism to restrict the rotation of the winch, which is only effective for low-speed and light-weight loads; 2. The wire-laying speed of the winch cannot be effectively controlled. As the weight of the cable being laid increases, the wire-laying speed will increase rapidly, and it is impossible to stop it in time. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a winch for underground cable installation. This winch can effectively control the cable laying speed and can stop quickly.

[0006] The technical solution to the technical problem solved by this utility model is as follows: An embodiment of this utility model provides a winch for underground cable installation, including a base, a fixed shaft, a wire roller, a reducer, a motor, a brake disc, and brake pads. The fixed shaft is horizontally arranged on the top of the base. The wire roller is mounted on the fixed shaft via bearings. The input end of the reducer is connected to the motor shaft, and the output end of the reducer is connected to the wire roller. The brake disc is fixed on the wire roller, and the brake pads are arranged on the base. The winch also includes a hydraulic cylinder, a speed limiting disc, a speed limiting band, and a speed limiter. The brake pads are open annular rings that wrap around the brake disc. The cylinder body and the telescopic rod of the hydraulic cylinder are respectively connected to the two openings of the brake pads. The speed limiting disc is fixed on the wire roller, and the speed limiter is fixed on the base. The speed limiting band connects the speed limiting disc and the speed limiter.

[0007] As an optimization, the speed limiter includes a housing, a steering wheel, a pressure wheel, a swing seat, and a tension spring. At least one steering wheel is provided, and the steering wheel is installed in the housing via a rotating shaft. The speed limiting band connects the speed limiting disc and the steering wheel. One end of the swing seat is installed in the housing via a rotating shaft, and the pressure wheel is installed at the other end of the swing seat. The two ends of the tension spring are respectively connected to the middle of the swing seat and the housing. One side of the speed limiting band is in contact with the inner wall of the housing, and the other side is in contact with the pressure wheel. The tension spring is disposed between the speed limiting band and the swing seat.

[0008] As an optimization, the speed limiter also includes a pressure block, which is disposed between the speed limiting strip and the inner wall of the housing. The pressure block and the pressure roller are disposed opposite each other on both sides of the speed limiting strip, and the pressure block is in contact with the side of the speed limiting strip.

[0009] As an optimization, the pressing block is cylindrical.

[0010] As an optimization, a set of speed limiting belts, speed limiting discs, and speed limiters are respectively installed on both sides of the online roller.

[0011] As an optimization, a set of brake discs, brake pads, and hydraulic cylinders are respectively arranged on both sides of the online roller.

[0012] As an optimization, the reducer includes gear one, gear two, bevel gear one, bevel gear two, gear three, gear four, and a housing. The motor is fixed outside the housing. Gear one is connected to the output shaft of the motor. Both ends of gear two are mounted in the housing through bearings. Gear one meshes with gear two. Bevel gear one is mounted on the rotating shaft of gear two. Bevel gear one meshes with bevel gear two. Bevel gear two is coaxial with gear three. Gear three meshes with gear four. Gear four is fixed on the roller and is coaxial with the roller.

[0013] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0014] 1. By setting a speed limiter, the winch can effectively control the wire laying speed; by setting the cylinder body of the hydraulic cylinder and the telescopic rod to connect to the two openings of the brake pads respectively, it can stop quickly.

[0015] 2. The pressure roller has a very small contact area with the speed limiter, so it is only necessary to set up support at the corresponding position. Too much support will increase the wear on the speed limiter. By setting up pressure blocks, the cylindrical pressure blocks can reduce the contact area with the speed limiter and reduce the wear on the speed limiter.

[0016] 3. By setting a speed limiting belt, speed limiting disc, and speed limiter on both sides of the online roller, the deceleration force can be made more uniform, thus improving the deceleration effect.

[0017] 4. By installing a set of brake discs, brake pads, and hydraulic cylinders on both sides of the online roller, the deceleration force can be made more uniform, enabling the winch to stop quickly while reducing wear and tear on the equipment. Attached Figure Description

Detailed Implementation

[0026] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] Figures 1 to 7 As one embodiment of this utility model, such as Figure 4 As shown, a winch for installing underground cables includes a base 1, a fixed shaft 2, a wire roller 3, a reducer 4, a motor 5, a brake disc 6, and brake pads 7. The fixed shaft 2 is horizontally mounted on top of the base 1. The wire roller 3 is mounted on the fixed shaft 2 via bearings. The input end of the reducer 4 is connected to the shaft of the motor 5, and the output end of the reducer 4 is connected to the wire roller 3. The brake disc 6 is fixed to the wire roller 3. The brake pads 7 are mounted on the base 1. A speed limiting disc 9 is fixed to the wire roller 3. A speed limiter 11 is fixed to the base 1. A speed limiting belt 10 connects the speed limiting disc 9 and the speed limiter 11. Figure 5 As shown, the winch also includes a hydraulic cylinder 8, a speed limiting disc 9, a speed limiting band 10, and a speed limiter 11. The brake pad 7 is an open annular shape, covering the brake disc 6. The cylinder body and telescopic rod of the hydraulic cylinder 8 are respectively connected to the two openings of the brake pad 7. The fixed shaft 2, the wire roller 3, the brake disc 6, and the speed limiting disc 9 are concentric.

[0028] The speed limiting band 10, speed limiting disc 9, and speed limiter 11 are each arranged in a set on both sides of the online roller 3. By installing a set of speed limiting bands 10, speed limiting discs 9, and speed limiters 11 on each side of the online roller 3, the deceleration force can be made more uniform, improving the deceleration effect. The brake disc 6, brake pads 7, and hydraulic cylinder 8 are each arranged in a set on both sides of the online roller 3. By installing a set of brake discs 6, brake pads 7, and hydraulic cylinders 8 on each side of the online roller 3, the deceleration force can be made more uniform, achieving rapid stopping of the winch while reducing wear and tear on the equipment.

[0029] like Figure 6As shown, the speed limiter 11 includes a housing 111, a steering wheel 112, a pressure wheel 113, a swing seat 114, and a tension spring 115. At least one steering wheel 112 is provided, and the steering wheel 112 is installed in the housing 111 through a rotating shaft. The speed limiting band 10 connects the speed limiting disc 9 and the steering wheel 112. One end of the swing seat 114 is installed in the housing 111 through a rotating shaft, and the pressure wheel 113 is installed at the other end of the swing seat 114. The two ends of the tension spring 115 are respectively connected to the middle of the swing seat 114 and the housing 111. One side of the speed limiting band 10 is in contact with the inner wall of the housing 111, and the other side is in contact with the pressure wheel 113. The tension spring 115 is disposed between the speed limiting band 10 and the swing seat 114. The speed limiter 11 also includes a pressure block 116, which is disposed between the speed limiting strip 10 and the inner wall of the housing 111. The pressure block 116 and the pressure roller 113 are disposed opposite each other on both sides of the speed limiting strip 10, with the pressure block 116 fitting against the side of the speed limiting strip 10. The pressure roller 113 has a small area of ​​action on the speed limiting strip 10, and only needs to be supported at the corresponding position. Too much support area would increase wear on the speed limiting strip 10. By setting the pressure block 116, wear on the speed limiting strip 10 can be reduced. The pressure block 116 is cylindrical. The cylindrical shape of the pressure block 116 reduces the contact area with the speed limiting strip 10. The tension spring 115 pulls the pressure roller 113 to engage with the speed limiting belt 10. When the speed limiting belt 10 rotates, it generates friction with the pressure roller 113. This friction causes the pressure roller 113 to move closer to the speed limiting belt 10, thereby increasing the pressure of the pressure roller 113 on the speed limiting belt 10. As the speed of the speed limiting belt 10 increases, the pressure of the pressure roller 113 on the speed limiting belt 10 increases, and the resistance experienced by the speed limiting belt 10 increases, thus limiting the movement of the speed limiting belt 10. This, in turn, limits the rotational speed of the wire roller 3, thereby controlling the wire feeding speed.

[0030] like Figure 7 As shown, the reducer 4 includes gear 1 41, gear 2 42, bevel gear 1 43, bevel gear 2 44, gear 3 45, gear 46, and housing 47. Motor 5 is fixed outside housing 47. Gear 1 41 is connected to the output shaft of motor 5. Both ends of gear 2 42 are mounted in housing 47 via bearings. Gear 1 41 meshes with gear 2 42. Bevel gear 1 43 is mounted on the rotating shaft of gear 2 42 and meshes with bevel gear 2 44. Bevel gear 2 44 is coaxial with gear 3 45. Gear 3 45 meshes with gear 46. Gear 46 is fixed on the wire roller 3 and is coaxial with the wire roller 3. The power from motor 5 is transmitted sequentially through gear 1 41, gear 2 42, bevel gear 1 43, bevel gear 2 44, gear 3 45, and gear 46, driving the wire roller 3 to rotate and enabling the winch to release the wire.

[0031] By setting a speed limiter 11, the winch can effectively control the wire laying speed; by setting the cylinder body and telescopic rod of the hydraulic cylinder 8 to be connected to the two openings of the brake pad 7 respectively, the retraction of the telescopic rod of the hydraulic cylinder 8 can tighten the brake pad 7 to generate a great friction force, thereby causing the winch to stop quickly.

[0032] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
