Description

Technical Field

[0001] This utility model relates to the technical field of oil drilling rig supporting equipment, and in particular to a new type of rope reversing machine for drilling rigs. Background Technology

[0002] The traveling system of an oil drilling rig is mainly used for lifting or lowering tubing, casing, and large mechanical equipment. It generally includes a hook, pulley block, wire rope, drum, dead rope retainer, and rope rewinding machine. One end of the wire rope is wound around the drum, and the other end is fixed to the dead rope retainer after passing through the pulley block. The dead rope retainer is also equipped with a tension sensor to detect the tension of the wire rope. The rope rewinding machine is used to replace the wire rope and is usually connected to the dead rope retainer.

[0003] The existing wire rope rewinding machine and dead rope fixing device are two separate pieces of equipment located in different places. When it is necessary to replace the wire rope, both the wire rope rewinding machine and the dead rope fixing device need to be operated at the same time, which makes the replacement of the wire rope very difficult and the replacement efficiency is low.

[0004] Therefore, it is necessary to propose a new type of wire rope changing machine for drilling rigs to reduce the difficulty of replacing wire ropes and improve the efficiency of wire rope replacement. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the great difficulty in replacing the wire rope of the existing oil drilling rig traveling system. A new type of rope-reversing machine for drilling rigs is provided.

[0006] The technical solution of this utility model is:

[0007] A novel rope rewinding machine for drilling rigs includes a support base and a drive motor. A roller is rotatably connected to the support base, and a fixing clamp is fixedly connected to the roller. A turntable is coaxially fixedly connected to one end of the roller. A drive wheel is installed at the output end of the drive motor and is tangent to the turntable. A fixing plate is coaxially and detachably connected to the other end of the roller. A tension sensor is installed on the fixing plate. A steel wire rope is wound around the roller, and one end of the steel wire rope is fixed to the fixing clamp.

[0008] Furthermore, it also includes a fixed base that is fixed to the ground, a base plate that is fixedly connected to the drive motor, a base plate that is rotatably connected to the fixed base, and a pre-tightening device that pulls the drive motor close to the turntable so that the drive wheel is tangent to the turntable.

[0009] Furthermore, the pretensioning device includes a spring and a pull rod. One end of the spring is fixedly connected to one end of the pull rod, the other end of the spring is fixedly connected to the support base, and the other end of the pull rod is rotatably connected to the base plate.

[0010] Furthermore, there are two springs, which are arranged side by side at one end of the pull rod.

[0011] Furthermore, the tie rod is hinged to the base plate.

[0012] Furthermore, the base plate and the mounting base are hinged.

[0013] Furthermore, the support base and the roller are rotatably connected via bearings.

[0014] Furthermore, there are at least four fixing clamps.

[0015] Furthermore, a rubber ring is coaxially fitted on the outer side of the turntable, and the rubber ring is fixedly connected to the turntable, with the rubber ring replacing the turntable and tangent to the drive wheel.

[0016] This utility model discloses a novel wire rope rewinding machine for drilling rigs. The drum is used to wind the wire rope. When replacing the wire rope, the fixing plate is first removed from the drum, and then the drive motor rotates the drum, releasing the new wire rope for replacement. The fixing clamp on the drum replaces the traditional dead-rope retainer to secure the end of the wire rope. After the wire rope is replaced, the drum stops rotating, and the fixing plate is reinstalled on the drum. The tension on the fixing clamp is transmitted to the drum, and then to the tension sensor through the fixing plate, thus enabling tension detection. Compared with traditional technology, this technical solution changes the structure of the wire rope rewinding machine, replacing the traditional dead-rope retainer. This eliminates the need for a dead-rope retainer during wire rope replacement; only the wire rope rewinding machine of this application is required to complete the replacement, reducing the difficulty and improving the efficiency of wire rope replacement.

[0020] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Example 1:

[0022] like Figure 1 and Figure 2As shown, this embodiment provides a novel rope rewinding machine for drilling rigs, including a support base 1 and a drive motor 2. A roller 3 is rotatably connected to the support base 1, and a fixing clamp 7 is fixedly connected to the roller 3. A turntable 4 is coaxially fixedly connected to one end of the roller 3. An active wheel 5 is installed at the output end of the drive motor 2. The active wheel 5 is tangent to the turntable 4. A fixing plate 6 is detachably connected to the other end of the roller 3. The detachable connection can be achieved by screws or pins. A tension sensor 8 is installed on the fixing plate 6. A steel wire rope is wound around the roller 3, and one end of the steel wire rope is fixed to the fixing clamp 7.

[0023] Preferably, it also includes a fixed base 9 fixed to the ground, a base plate 10 fixedly connected to the drive motor 2, and a rotatable connection between the base plate 10 and the fixed base 9. The support base 1 is provided with a pre-tightening device, which pulls the drive motor 2 closer to the turntable 4 so that the drive wheel 5 is tangent to the turntable 4. Preferably, the pre-tightening device includes a spring 12 and a pull rod 11. One end of the spring 12 is fixedly connected to one end of the pull rod 11 by a hook, and the other end of the spring 12 is fixedly connected to the support base 1 by a hook. The other end of the pull rod 11 is rotatably connected to the base plate 10. Preferably, there are two springs 12, which are arranged side by side at one end of the pull rod 11. Preferably, the pull rod 11 is connected to the base plate 10. Preferably, the base plate 10 and the fixed seat 9 are hinged. Preferably, the support seat 1 and the roller 3 are rotatably connected by bearings. Preferably, there are at least 4 fixed clamps 7. Preferably, a rubber ring 13 is coaxially sleeved on the outer side of the turntable 4. The rubber ring 13 is fixedly connected to the turntable 4 with screws. The rubber ring 13 replaces the turntable 4 and is tangent to the drive wheel 5. The rubber ring 13 can increase the friction and prevent the drive wheel 5 from slipping, thus ensuring the driving effect of the drive motor 2. The pre-tightening device can adjust the pre-tightening pressure between the drive wheel 5 and the rubber ring 13. Under the elastic traction of the spring 12, the drive wheel 5 can always be in contact with the rubber ring 13, thereby preventing the drive wheel 5 from slipping on the rubber ring 13.

[0024] In use, the roller 3 is used to wind the wire rope. When replacing the wire rope, the fixing plate 6 is first removed from the roller 3, and then the drive motor 2 drives the roller 3 to rotate, so that the roller 3 releases the new wire rope for replacement. The fixing clamp 7 set on the roller 3 can replace the traditional dead rope fixer to fix the end of the wire rope. After the wire rope is replaced, the roller 3 stops rotating, and the fixing plate 6 is reinstalled on the roller 3. The tension on the fixing clamp 7 can be transmitted to the roller 3, and then transmitted to the tension sensor 8 through the fixing plate 6, thereby realizing the detection of tension. Compared with the traditional technology, this technical solution changes the structure of the wire rope rewinding machine and replaces the traditional dead rope fixer, so that the dead rope fixer is not needed when replacing the wire rope. Only the wire rope rewinding machine of this application needs to be operated to complete the replacement of the wire rope, reducing the difficulty of replacing the wire rope and improving the replacement efficiency of the wire rope.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
