[0013] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0015] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0016] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0017] like Figure 1-2 As shown, a preferred embodiment of the present invention provides a winch structure suitable for longitudinal arrangement of vehicle-mounted drilling and repair rigs, including a winch base 1, a winch frame 2, a drum device 3, a power transmission system 4, and a guide device 5; The winch base 1 is axially parallel to the rectangular frame 6 of the vehicle-mounted drilling and repair rig, and the winch frame 2 is fixedly mounted on the winch base 1; the derrick 9 is located between the frame 6 and the wellhead 7; as shown Figure 1 As shown, both the winch base 1 and the frame 6 can be rectangular.

[0018] The drum device 3 includes a drum 31 and a drum shaft 32. The drum is coaxially sleeved on the drum shaft, and both ends of the drum shaft are rotatably mounted on the winch frame 2. Drilling tools or well workover tools are wound around the drum by a pull rope. The power transmission system 4 is mounted on the winch base, and the output end of the power transmission system 4 is connected to the drum shaft through a coupling or hollow shaft, which is used to drive the drum shaft to rotate the drum, thereby driving the drilling tools or workover tools to be lowered or raised. The guide device 5 is fixedly installed on the winch frame 2 and symmetrically distributed on both sides of the drum, and is used to guide the pull rope; The axis of the drum is perpendicular to the opening direction of the derrick, and the opening of the derrick 9 is set facing the wellhead 7 to cooperate with the guide device 5 to guide the drilling tool or workover tool from the drum through the derrick opening directly to the wellhead 7.

[0019] In the above technical solution, the winch structure can be stably installed on the frame 6 of the vehicle-mounted drilling and repair machine with its axis parallel to the ground. Figure 1As shown, the rectangular winch structure is placed longitudinally on the rectangular frame. Compared to the conventional method where the entire winch structure, including the winch base and winch frame, is placed horizontally and vertically on the frame, this arrangement adapts to longitudinal layout requirements, avoids occupying too much lateral space, and is more suitable for truck-mounted drilling and workover rigs installed on the main body of the vehicle. The symmetrical arrangement of the guide device 5 effectively prevents the wire rope from deviating, ensuring the precise movement path of the drilling tools or workover tools; the reliable connection between the power transmission system 4 and the drum shaft ensures high power transmission efficiency and no power loss; the axis of the drum is perpendicular to the direction of the derrick opening, and the derrick opening is set towards the wellhead 7, allowing the drilling tools or workover tools to directly reach the wellhead 7 from the drum through the derrick opening.

[0020] Another technical solution also includes a braking system 8, which includes a main brake and a secondary brake. The braking ends of the main brake and the secondary brake are configured to cooperate with the roller to brake the rotation of the roller. The main brake is a disc brake and the secondary brake is a pneumatic brake.

[0021] In the above technical solution, the main brake adopts a disc structure, which can achieve smooth braking and meet the needs of frequent braking in normal operation; the auxiliary brake adopts a pneumatic brake, which has a fast pneumatic drive response speed. At the same time, as an emergency braking solution, it effectively improves the redundancy of the braking system 8 and avoids safety accidents caused by main brake failure.

[0022] In another technical solution, the winch structure also includes a control system, which is electrically connected to the power transmission system 4 and the braking system 8 via electrical lines to realize remote control of the winch.

[0023] In another technical solution, the power transmission system 4 includes a motor, a gearbox, a coupling, and an auxiliary motor; the output end of the auxiliary motor is fixedly connected to the input end of the gearbox via a coupling; the output end of the motor is fixedly connected to the input end of the gearbox via a coupling; and the output end of the gearbox is fixedly connected to one end of the roller shaft via a coupling.

[0024] In the above technical solution, the power transmission system 4 uses a motor as the main drive, and the auxiliary motor provides a backup plan for the power transmission system 4, avoiding operation interruption due to motor failure and improving the continuous operation capability of the equipment. Overall, the power transmission system 4 has a reasonable structural design, high power transmission efficiency, and adapts to the power requirements of different working conditions, providing a reliable power guarantee for the stable operation of the winch structure.

[0025] In another technical solution, the guiding device 5 includes two guide wheels 51, which are symmetrically arranged on both sides of the drum along the axial direction. The grooves of the two guide wheels are arranged opposite to each other, forming a guiding space between them, and the wire rope is located in the guiding space.

[0026] In the above technical solution, the two guide rope wheels of the guiding device 5 are symmetrically arranged to ensure the accurate guiding direction of the wire rope and avoid lateral displacement or tangling during the movement of the wire rope, thereby improving the stability of the winch structure during operation. Through the setting of the guiding device 5, the movement path of the wire rope is effectively controlled, ensuring that the drilling tools or workover tools can smoothly pass through the opening of the derrick to reach the wellhead 7, avoiding operation interruption or equipment damage caused by wire rope deviation. At the same time, it simplifies the winding and release process of the wire rope, improves the operating efficiency of the winch structure, and meets the high-efficiency operation requirements of the vehicle-mounted drilling and workover rig.

[0027] In another technical solution, the derrick is a portal frame structure with its opening facing the wellhead 7.

[0028] In the above technical solution, the derrick adopts a portal frame structure, which has high overall rigidity and stability, and can withstand the weight and lateral force of the drilling tools or workover tools, preventing the derrick from deforming or tilting during operation and improving operational safety. By setting the opening of the derrick towards the wellhead 7 and cooperating perpendicularly with the axis of the drum, it is ensured that the drilling tools or workover tools can directly reach the wellhead 7 from the drum through the derrick opening, shortening the movement path of the drilling tools or workover tools, reducing operation time, and improving the operating efficiency of the truck-mounted drilling and workover rig.

[0029] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
