Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted workover rigs. More specifically, this invention relates to a rotating operating cab that is adaptable to a vehicle-mounted workover rig and has adjustable space. Background Technology

[0002] The driller's cab for minor repair operations on vehicle-mounted workover rigs is typically fixed to the left rear side of the rig platform, or equipped with a driller's control box located at the inverted triangle of the derrick, with the driller operating from outdoors. During operations, the operator's view of the wellhead from inside the driller's cab is obstructed by the inverted triangle of the derrick, the rear support of the derrick, and the wellhead operating tools. If the driller operates from outdoors, the working environment is poor, the workload is heavy, and fatigue is easily incurred, affecting operational safety. In addition, three support operators are required for the workover operation, which brings inconvenience and safety hazards to the operation. To address these issues, existing technologies typically involve making the driller's cab, originally fixed to the rear of the vehicle, a rotatable structure. The driller's cab is mounted on a rotating bracket, with a telescopic cylinder between the inner side of the bracket and the main frame. The cylinder's inlet and outlet oil circuits are connected to the main vehicle's oil circuit. When the equipment arrives at the well site, the telescopic cylinder is operated to unfold the rotating bracket, and after adjusting to a suitable angle, the rotating support is fixed. The driller's cab's rotation angle is then adjusted using cylinders at the bottom, providing the operator with the optimal viewing angle for the well workover operation. During transport, the driller's cab retracts along with the rotating support into the main vehicle and locks to the frame. However, due to road transport limitations, the space allocated to the driller's cab is limited. The cab's dimensions are restricted by the top derrick, surrounding lifting cylinders, and width, meaning it can only accommodate a small person. Leg extension is difficult, and prolonged operation can easily lead to fatigue, affecting operational comfort and safety. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] To achieve these objectives and other advantages according to the present invention, a rotating operating cabin that is adaptable to a vehicle-mounted workover rig and has adjustable space is provided, comprising:

[0005] The control room includes a fixed compartment and an extended compartment. An operating table is provided at one end of the fixed compartment, and the extended compartment is slidably disposed at the other end of the fixed compartment opposite to the operating table.

[0006] An extension drive device, which is located in the operating room, is used to drive the extension compartment to extend or fully retract into the fixed compartment relative to the fixed compartment;

[0007] The bracket is a telescopic structure; the fixed part of the bracket is rotatably connected to the rear seat of the vehicle-mounted well workover rig, and its movable part is rotatably connected to the bottom of the fixed compartment.

[0008] A telescopic hydraulic cylinder, with its two ends hinged to the fixed part and the movable part of the bracket respectively, is used to drive the extension and retraction of the bracket;

[0009] A first rotary cylinder is fixedly mounted on the rear seat of the vehicle. The rotating shaft of the first rotary cylinder is fixedly connected to the fixed part of the bracket, so as to drive the bracket to rotate relative to the rear seat of the vehicle.

[0010] The second rotary cylinder is fixedly mounted on the movable part of the bracket. The rotating shaft of the second rotary cylinder is fixedly connected to the bottom of the fixed chamber, so as to drive the operating chamber to rotate relative to the bracket.

[0011] Preferably, a telescopic slide rail is provided between the outer wall of the expansion compartment and the inner wall of the fixed compartment.

[0012] Preferably, a PTFE sliding plate is fixedly installed at the bottom of the expansion compartment.

[0013] Preferably, the expansion compartment is provided with a support leg on the side opposite to the fixed compartment, and the support leg is a retractable structure.

[0014] Preferably, the expansion drive device includes a drive motor and a T-type differential fixedly installed in the expansion compartment. The T-type differential has one input end and two output ends. The output end of the drive motor is fixedly connected to the input end of the T-type differential. A gear is fixedly connected to one output end of the T-type differential, and a roller is fixedly connected to the other output end. A rack that meshes with the gear is provided on the inner wall of the fixed compartment along the sliding direction of the expansion compartment.

[0015] Preferably, one end of the support leg is hinged to the side wall of the expansion compartment, and the other end is fixedly connected to a take-up rope; the take-up rope passes through the side wall of the expansion compartment and is wound around the roller.

[0017] Preferably, the rack includes an upper rack and a lower rack arranged opposite each other, and the two ends of the upper rack and the lower rack are respectively connected by vertical rods.

[0018] Preferably, both the support leg and the extension drive device are provided in pairs, with each pair corresponding to the other.

[0019] Preferably, a seat is provided inside the fixed compartment near the operating table, and the seat is slidably connected to the inner bottom of the fixed compartment.

[0020] The present invention has at least the following beneficial effects:

[0021] The present invention provides a rotating operator's cab that is adaptable to vehicle-mounted workover rigs and has adjustable space. The position of the operator's cab is precisely adjusted using a first and second rotary cylinder, ensuring the driller's field of vision is directly facing the wellhead. The length of the support frame is adjusted using a telescopic cylinder, keeping the operator's cab away from explosion-proof areas to ensure the safety of the personnel. Furthermore, the operator's cab includes a fixed compartment and an extended compartment. The extended compartment can extend relative to the fixed compartment or completely retract into the fixed compartment under the action of an extension drive device, realizing spatial expansion of the operator's cab. This not only meets transportation size requirements but also provides the driller's cab with a better field of vision and more spaciousness during operation, improving operational comfort and safety.

[0022] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0029] 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.

[0030] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

They are only for the convenience of describing this invention 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, they should not be construed as limitations on this invention.

[0031] like Figures 1 to 6 As shown, the present invention provides a rotating operating room that is adaptable to a vehicle-mounted well workover rig and has adjustable space, comprising:

[0032] The control room 1 includes a fixed compartment 11 and an extended compartment 12. An operating table 5 is provided at one end of the fixed compartment 11, and the extended compartment 12 is slidably disposed at the other end of the fixed compartment 11 opposite to the operating table 5.

[0033] An extension drive device is provided in the operating room 1 to drive the extension compartment 12 to extend or fully retract into the fixed compartment 11 relative to the fixed compartment 11.

[0034] The bracket 4 is a telescopic structure; the fixed part of the bracket 4 is rotatably connected to the rear seat 2 of the vehicle-mounted well repair machine, and its movable part is rotatably connected to the bottom of the fixed compartment 11.

[0035] The telescopic cylinder 8 has its two ends hinged to the fixed part and the movable part of the bracket 4, respectively, to drive the extension and retraction of the bracket 4;

[0036] The first rotary cylinder 3 is fixedly mounted on the rear seat 2. The rotating shaft of the first rotary cylinder 3 is fixedly connected to the fixed part of the bracket 4, so as to drive the bracket 4 to rotate relative to the rear seat 2.

[0037] The second rotary cylinder 6 is fixedly mounted on the movable part of the bracket 4. The rotating shaft of the second rotary cylinder 6 is fixedly connected to the bottom of the fixed chamber 11 to drive the operating chamber 1 to rotate relative to the bracket 4.

[0038] In this technical solution, considering the surface conditions at the well site, the first rotary cylinder 3 rotates the operating room 1 to the outside of the vehicle body, coarsely adjusting it to a suitable angle; then, the second rotary cylinder 6 precisely adjusts the rotation angle of the operating room 1, ensuring the driller's field of vision faces the wellhead; the movable part of the bracket 4 can slide relative to the fixed part to adjust the bracket length; the telescopic cylinder 8 controls the sliding of the movable part of the bracket 4 relative to the fixed part to adjust the length of the bracket 4, ensuring the operating room 1 is away from the explosion-proof area and guaranteeing personal safety. After the above adjustments are completed, the extension drive device extends the extension compartment 12 from the rear end of the fixed compartment 11 (the end where the operating platform 5 is located is the front end), expanding the internal space of the operating room 1 and providing a more comfortable working space for the operator, ensuring work efficiency and safety. Further, as... Figure 6 As shown, the expansion compartment 12 is a box structure with an opening on one side, consisting of five panels, with the opening facing the fixed compartment. Each panel includes two layers of panels and a frame 121 sandwiched between them. The frame 121 is a rectangular frame composed of four aluminum tubes, with square timbers placed inside the tubes. The frame 121 increases the overall strength of the expansion compartment 12, and the square timbers increase the holding force of the expansion compartment 12 during assembly. The bottom surface of the expansion compartment 12 extends outward from the center of the fixed compartment 11 to form an extension section, ensuring that the main body of the expansion compartment 12 remains within the fixed compartment 11 even after it has fully extended out, facilitating subsequent retraction of the expansion compartment 12.

[0039] In actual use, a heating and cooling air conditioner can be installed on the expansion chamber 12. As the expansion chamber 12 unfolds, the air conditioner moves backward without occupying internal operating space. Observation windows are provided on the top, front, left, right sides, and door of the fixed chamber 11. One side is a sliding type, while the others are fixed. The top and front observation windows are equipped with detachable protective grilles to provide safety protection for the driller during operations. The observation windows on the top and front of the fixed chamber 11 are integral curved glass, with the front glass angled and extending to the top for easy observation of the working conditions above. An explosion-proof sight glass is installed at the front of the fixed chamber 11 to illuminate the weight indicator.

[0040] In another technical solution, a telescopic slide rail 9 is provided between the outer wall of the expansion compartment 12 and the inner wall of the fixed compartment 11. Depending on the maximum length of the expansion compartment 12 extending relative to the fixed compartment 11, a conventional two-stage or multi-stage telescopic slide rail is selected. The two relatively sliding parts of the telescopic slide rail are fixedly connected to the expansion compartment 12 and the fixed compartment 11, respectively. Preferably, there are two telescopic slide rails 9, symmetrically arranged at the lower end of the expansion compartment 12. The telescopic slide rails 9 improve the stability of the expansion compartment 12 during sliding and simultaneously limit the horizontal movement of the expansion compartment 12, preventing lateral swaying.

[0041] In another technical solution, a PTFE sliding plate is fixedly installed at the bottom of the expansion compartment 12 to reduce the resistance when the expansion compartment 12 slides.

[0042] In another technical solution, such as Figure 2 As shown, the expansion compartment 12 has a support leg 10 on the side opposite to the fixed compartment 11. The support leg 10 is a telescopic structure. The support leg 10 is used to support the expansion compartment 12 after it extends out of the fixed compartment 11, ensuring the stability of the operating room 1. The length of the support leg 10 can be adjusted to adapt to uneven road surfaces.

[0043] Furthermore, such as Figure 3 and Figure 4 As shown, the expansion drive device includes a drive motor 13 and a T-type differential 14 fixedly installed inside the expansion compartment 12. The T-type differential 14 has one input end and two output ends. The output end of the drive motor 13 is fixedly connected to the input end of the T-type differential 14. A gear 15 is fixedly connected to one output end of the T-type differential 14, and a roller is fixedly connected to the other output end. A rack that meshes with the gear 15 is provided on the inner wall of the fixed compartment 11 along the sliding direction of the expansion compartment 12. The drive motor 13 and the T-type differential 14 simultaneously drive the gear 15 and the roller to rotate. Through the cooperation of the gear 15 and the rack, the expansion compartment 12 slides relative to the fixed compartment 11.

[0044] One end of the outrigger 10 is hinged to the side wall of the expansion compartment 12, and the other end is fixedly connected to a retractable rope 17. The retractable rope 17 passes through the side wall of the expansion compartment 12 and is wound around the roller. By rotating the roller, the retractable rope 17 is retracted, thereby enabling the outrigger 10 to be retracted or extended. That is, when the expansion compartment 12 is extended, the retractable rope 17 is slowly lowered. At this time, the outrigger 10 rotates downward around the hinge point with the expansion compartment under the action of gravity until it is vertically supported on the ground. When the expansion compartment 12 is retracted, the retractable rope 17 is wound back, causing the outrigger 10 to rotate upward around the hinge point with the expansion compartment until it is in contact with the side wall of the expansion compartment 12.

[0045] Furthermore, the roller includes a large-diameter section 16 and a small-diameter section 18 coaxially arranged. The take-up rope 17 is wound around the large-diameter section 16; a traction rope 19 is wound around the small-diameter section 18. The take-up rope 17 and the traction rope 19 are wound in opposite directions. The movable part of the traction rope 19 is fixedly connected to the inner top of the fixed compartment 11. Considering that the extended compartment 12 is unsupported during extension and will deflect downwards under gravity, increasing torque between the telescopic guide rail 9, the gear 15, and the rack, and causing increased wear and safety hazards over time, the traction rope 19, fixedly connected to the inner top of the fixed compartment 11, provides traction from above, improving the stability of the extended compartment 12 during extension. The take-up rope 17 and the traction rope 19 are wound in opposite directions on the roller, allowing them to simultaneously loosen or tighten when the roller rotates, satisfying the sliding requirements of the extended compartment 12. Furthermore, by setting the roller to a large-diameter section 16 and a small-diameter section 18, the problem of inconsistent strokes between the take-up / release rope 17 and the traction rope 19 is solved. In use, the roller is supported by a base 20 mounted on the top of the extension compartment 12. Bearing seats 21 are provided on both sides of the base 20 to provide support to both ends of the roller. Preferably, a connecting plate 22 is provided on the inner top of the fixing compartment 11 to keep the connection between the traction rope 19 and the fixing compartment 11 horizontal.

[0046] like Figures 2 to 4 As shown, both the support leg 10 and the extension drive device are configured in pairs, with each pair corresponding to the other.

[0047] Furthermore, such as Figure 5As shown, the rack includes an upper rack 23 and a lower rack 25 arranged opposite each other, with the two ends of the upper rack 23 and the lower rack 25 connected by vertical rods 24. The vertical rods 14 at both ends constitute a limit for the expansion compartment 12. Preferably, proximity switches are respectively provided at both ends of the rack near the vertical rods 24. The proximity switches are connected to a controller, which controls the opening and closing of the drive motor 13. Alternatively, they can be directly connected to an alarm device to remind the expansion compartment 12 that it has approached its limit position.

[0048] In another technical solution, a seat 7 is disposed inside the fixed compartment 11 near the operating table 1, and the seat 7 is slidably connected to the inner bottom of the fixed compartment 11. The seat 7 can be slidable inside the fixed compartment 11 using a conventional sliding connection structure. When the extension compartment 12 is extended, the seat 7 can be slid backward to free up legroom for the staff and alleviate the confinement of the interior space.

[0049] Although embodiments of the present invention 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 the present invention. 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, the present invention is not limited to the specific details and illustrations shown and described herein.
