Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a dual-motor driven winch for a trailer drilling rig. Background Technology

[0002] Currently, high-power winches commonly used in oil fields are generally powered by two or more motors. However, the existing arrangement for dual-motor driven winches is to have a gearbox on one side of the width direction. The input shaft of the gearbox is connected to the motor, and the output shaft is connected to the drum. The two input interfaces of the same input shaft are arranged opposite each other along the width direction (the two input interfaces are distributed at 180°). That is, the motors are arranged on both sides of the gearbox along the width direction of the winch. This structure results in the overall width of the winch being too wide, making it impossible to install conventional winches on trailers and failing to meet the requirements for rapid overall movement of the drilling rig.

[0003] Therefore, it is necessary to propose an improvement to the dual-motor driven winch for trailer drilling rigs to overcome the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art and provide a dual-motor driven winch for a trailer drilling rig.

[0005] The technical solution of this utility model is:

[0006] A dual-motor driven winch for a trailer drilling rig includes a winch frame, a first motor, a second motor, a gear reducer, and a drum assembly. The first motor, the second motor, the gear reducer, and the drum assembly are all mounted on the winch frame. The first motor and the second motor are both connected to the gear reducer for transmission. The output shaft axis of the first motor is perpendicular to the output shaft axis of the second motor. The drum assembly is connected to the gear reducer.

[0007] Preferably, the gear reducer includes a first input shaft, a second input shaft, an intermediate shaft, and a reduction output shaft. A first bevel gear is disposed on the first input shaft, a second bevel gear and a first spur gear are disposed on the second input shaft, and the first bevel gear meshes with the second bevel gear. A second spur gear and a third spur gear are disposed on the intermediate shaft, and the first spur gear meshes with the second spur gear. A fourth spur gear is disposed on the reduction output shaft, and the third spur gear meshes with the fourth spur gear.

[0008] Preferably, the output shaft of the first motor is connected to the first input shaft via a motor coupling, and the output shaft of the second motor is connected to the second input shaft via a motor coupling.

[0009] Preferably, the first motor and the second motor rotate in opposite directions.

[0010] Preferably, the roller assembly is connected to the reduction output shaft via a roller coupling.

[0011] Preferably, hydraulic disc brakes are installed on the hubs at both ends of the drum assembly, and a disc brake hydraulic station power unit and a disc brake hydraulic station valve group unit are installed on the winch frame. The disc brake hydraulic station power unit controls the hydraulic disc brake through the disc brake hydraulic station valve group unit.

[0012] Preferably, a lubrication station is also provided on the winch frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention mounts the first and second input shafts of the gear reducer at a 90° angle, with the first and second motors located at the rear and left sides of the gear reducer, respectively. The drum assembly is arranged on the left side of the gear reducer, reducing the width of the winch frame and thus the overall width of the winch. This allows the winch to be mounted on a trailer, resulting in a compact overall system layout that meets the requirements for towing the derrick and winch as a single towing module. It is suitable for towed drilling rigs or vehicle-mounted drilling rigs. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] like Figure 1 As shown, a dual-motor driven winch for a trailer drilling rig includes a winch frame 6, a first motor 1-1, a second motor 1-2, a gear reducer 3, a drum assembly 9, a disc brake hydraulic station power unit 5-1, a disc brake hydraulic station valve group unit 5-2, and a lubrication station 4. The first motor 1-1, the second motor 1-2, the gear reducer 3, the drum assembly 9, the disc brake hydraulic station power unit 5-1, the disc brake hydraulic station valve group unit 5-2, and the lubrication station 4 are all integrated and installed on the winch frame 6, and none of them exceed the area projection range of the winch frame 6. The overall structure is compact and occupies a small area.

[0019] like Figure 1 As shown, the gear reducer 3 includes a first input shaft 3-1, a second input shaft 3-2, an intermediate shaft 3-9, and a reduction output shaft 3-10. The first input shaft 3-1 and the second input shaft 3-2 are installed perpendicularly, that is, the axis of the first input shaft 3-1 and the axis of the second input shaft 3-2 are at 90°. A first bevel gear 3-7 is connected to the first input shaft 3-1, and a second bevel gear 3-8 and a first spur gear 3-3 are connected to the second input shaft 3-2. The first bevel gear 3-7 meshes with the second bevel gear 3-8, and the first bevel gear 3-7 is identical to the second bevel gear 3-8. A second spur gear 3-4 and a third spur gear 3-5 are sequentially connected to the intermediate shaft 3-9. The first spur gear 3-3 meshes with the second spur gear 3-4. Gears 3-4 mesh, and a fourth spur gear 3-6 is connected to the reduction output shaft 3-10. The third spur gear 3-5 meshes with the fourth spur gear 3-6. The input power from the first input shaft 3-1 and the second input shaft 3-2 is transmitted to the reduction output shaft 3-10 after meshing and turning through the first bevel gear 3-7 and the second bevel gear 3-8. The transmission is then transmitted through a first-stage transmission of the first spur gear 3-3 meshing with the second spur gear 3-4 and a second-stage transmission of the third spur gear 3-5 meshing with the fourth spur gear 3-6. The outer diameter of the first spur gear 3-3 is smaller than that of the second spur gear 3-4, and the outer diameter of the third spur gear 3-5 is smaller than that of the fourth spur gear 3-6, thus achieving speed reduction and torque increase.

[0020] like Figure 1 As shown, the first motor 1-1 is installed on the rear side of the gear reducer 3. The output shaft of the first motor 1-1 is connected to the first input shaft 3-1 through the motor coupling 2. The power of the first motor 1-1 is transmitted to the first input shaft 3-1 through the motor coupling 2. The second motor 1-2 is installed on the left side of the gear reducer 3. The output shaft of the second motor 1-2 is connected to the second input shaft 3-2 through the motor coupling 2. The power of the second motor 1-2 is transmitted to the second input shaft 3-2 through the motor coupling 2. In use, the first motor 1-1 and the second motor 1-2 rotate in opposite directions. For example, when lifting the drill rod, the first motor 1-1 rotates clockwise (viewed from the drive end), and the second motor 1-2 rotates counterclockwise (viewed from the drive end). Then, through the meshing of the first bevel gear 3-7 and the second bevel gear 3-8, the power of the first motor 1-1 and the second motor 1-2 is superimposed.

[0021] like Figure 1As shown, the drum assembly 9 is installed on the left side of the gear reducer 3, on the same side as the second motor 1-2. The drum assembly 9 is connected to the reduction output shaft 3-10 through the drum coupling 8. The power of the first motor 1-1 and the second motor 1-2 is transmitted to the reduction output shaft 3-10, and then drives the drum assembly 9 through the drum coupling 8. Hydraulic disc brakes 7 are installed on the hubs at both ends of the drum assembly 9 to realize the braking of the drum assembly 9, ensuring the safe and stable operation of the drum assembly 9. It has high braking capacity, fast response speed, and balanced braking. The hydraulic disc brakes 7 are controlled by the disc brake hydraulic station power unit 5-1 and the disc brake hydraulic station valve group unit 5-2 installed on the winch frame 6.

[0022] like Figure 1 As shown, since the output shaft axes of the first motor 1-1 and the second motor 1-2 are distributed at 90°, there is sufficient space on the winch frame 6 between the first motor 1-1 and the second motor 1-2 for the installation of the disc brake hydraulic station power unit 5-1, the disc brake hydraulic station valve group unit 5-2 and the lubrication station 4, making the layout on the winch frame 6 more compact and the overall size of the winch frame 6 smaller.

[0023] like Figure 1 As shown, the first spur gear 3-3 and the second spur gear 3-4 are arranged on the left side of the gear reducer 3, and the third spur gear 3-5 and the fourth spur gear 3-6 are arranged on the right side of the gear reducer 3. The gear reducer 3 is recessed on the left side near the roller assembly 9 to reduce the space of the gear reducer 3, facilitate the installation of the roller coupling 8 and the roller assembly 9, and reduce the overall width.

[0024] This invention mounts the first input shaft 3-1 and the second input shaft 3-2 of the gear reducer 3 at a 90° angle, so that the first motor 1-1 and the second motor 1-2 are located on the rear and left sides of the gear reducer 3, respectively. The drum assembly 9 is arranged on the left side of the gear reducer 3, and the width of the winch frame 6 is reduced, thereby reducing the overall width of the winch, so that the winch can be mounted on a trailer. The overall system is compact and meets the towing requirements of the derrick and winch as a towing module. It is suitable for towing drilling rigs or vehicle-mounted drilling rigs.

[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.
