Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted workover rigs, and more particularly to a rotating operating room which is adapted to a vehicle-mounted workover rig and has adjustable space. Background Art

[0002] The driller's cabin equipped for minor repair work of the vehicle-mounted workover rig is usually fixedly installed on the left rear side of the vehicle platform, or equipped with a driller's operating box at the inverted triangle of the derrick, and the driller stands outside to operate. During operation, the operator in the driller's cabin observes the wellhead, but his view is blocked by the inverted triangle of the derrick, the rear support of the derrick, and the wellhead operating tools near the wellhead. If the operator stands outside to operate the driller's box, the driller's working environment is poor, the intensity is high, and it is easy to get tired and affect the safety of the operation. In addition, three supporting operators are required to perform the workover operation, which brings inconvenience and safety hazards to the operation. In order to solve the above problems, the prior art usually makes the driller's room originally fixed at the rear of the vehicle into a rotatable structure, installs the driller's room on the rotating bracket, and provides a telescopic oil cylinder between the inner side of the bracket and the main beam of the frame. The inlet and outlet oil circuits of the oil cylinder are connected with the oil circuit of the main vehicle. When the equipment arrives at the well site for operation, the telescopic oil cylinder is operated to unfold the rotating bracket, and the rotating bracket is fixed after being adjusted to a suitable angle; then the driller's room rotation angle is adjusted by the oil cylinder at the bottom of the driller's room, so that the operator in the driller's room can obtain the best viewing angle for observing the well repair operation. During vehicle transportation, the driller's room is retracted into the main vehicle with the rotating bracket and locked with the frame for transportation. However, the vehicle-mounted well repair rig is affected by road transportation, and the space reserved for the driller's room is limited. The driller's room body is limited by the top derrick, the surrounding lifting oil cylinders and the width. The driller's room can only accommodate a thin person to enter and operate; it is difficult to unfold the legs and feet, and long-term operation can easily make people feel tired, affecting the comfort and safety of the operation.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

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

[0032] The operating room 1 comprises a fixed compartment 11 and an expansion compartment 12, wherein an operating table 5 is arranged at one end of the fixed compartment 11, and the expansion compartment 12 is slidably arranged at the other end of the fixed compartment 11 opposite to the operating table 5;

[0033] An expansion drive device, which is disposed in the operating room 1 and is used to drive the expansion chamber 12 to extend relative to the fixed chamber 11 or to fully retract into the fixed chamber 11;

[0034] The bracket 4 is a retractable structure; the fixed portion of the bracket 4 is rotatably connected to the tail seat 2 of the vehicle-mounted workover rig, and the movable portion is rotatably connected to the bottom of the fixed compartment 11;

[0035] A telescopic oil cylinder 8, two ends of which are respectively hinged to the fixed part and the movable part of the bracket 4, for driving the bracket 4 to extend and retract;

[0036] A first rotating cylinder 3, which is fixedly disposed on the tail seat 2, wherein a rotating shaft of the first rotating cylinder 3 is fixedly connected to a fixed portion of the bracket 4, so as to drive the bracket 4 to rotate relative to the tail seat 2;

[0037] The second rotary cylinder 6 is fixedly disposed on the movable portion of the bracket 4 , and the rotating shaft of the second rotary cylinder 6 is fixedly connected to the bottom of the fixed bin 11 to drive the operating room 1 to rotate relative to the bracket 4 .

[0038] In this technical solution, in combination with the ground conditions of the well site operation, the operating room 1 is rotated to the outside of the vehicle body by the first rotating cylinder 3 and roughly adjusted to a suitable angle; then the rotation angle of the operating room 1 is precisely adjusted by the second rotating cylinder 6 so that 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 length of the bracket; the movable part of the bracket 4 is controlled by the telescopic cylinder 8 to slide relative to the fixed part to adjust the length of the bracket 4, so that the operating room 1 is away from the explosion-proof area to ensure personal safety. After the above adjustments are completed, the expansion compartment 12 is extended from the rear end of the fixed compartment 11 (the end where the operating table 5 is located is the front end) by the expansion drive device to expand the internal space of the operating room 1 and provide a more comfortable working space for the operator to ensure work efficiency and safety. Further, if Figure 6 As shown, the expansion bin 12 is a box structure with one side open and composed of five panels, and the open side faces the fixed bin; the panel body includes two layers of panels and a frame 121 sandwiched between the two layers of panels, and the frame 121 is a rectangular frame composed of four aluminum tubes, and square wood is arranged inside the aluminum tubes. The overall strength of the expansion bin 12 is increased by the slide 121, and the square wood can increase the nail holding force of the expansion bin 12 during assembly. The end of the bottom surface of the expansion bin 12 close to the center of the fixed bin 11 extends outward to form an extension section to ensure that the main body of the expansion bin 12 does not detach from the fixed bin 11 after it is fully extended out of the fixed bin 11, so as to facilitate the subsequent retraction of the expansion bin 12.

[0039] In actual use, a heating and cooling air conditioner can be installed on the expansion bin 12. When the expansion bin 12 is unfolded, the heating and cooling air conditioner will move backwards and will not occupy the internal operating space. Observation windows are provided on the top surface, front end, left and right sides and door of the fixed bin 11, one side of which is a push-pull type and the others are fixed. In addition, a protective fence that can be removed as a whole is installed on the outside of the top and front observation windows to provide safety protection for the driller operator during operation. The observation window glass on the top surface and the front end of the fixed bin 11 is an integral curved glass, and the glass at the front end is tilted and extends to the top, so that the driller operator can observe the top operation status. The front of the fixed bin 11 is equipped with an explosion-proof sight glass for illuminating the weight indicator.

[0040] In another technical solution, a telescopic slide rail 9 is provided between the outer wall of the expansion bin 12 and the inner wall of the fixed bin 11. According to the maximum length of the expansion bin 12 extending relative to the fixed bin 11, a conventional two-stage or multi-stage telescopic slide rail is selected accordingly, and the two relatively sliding parts of the telescopic slide rail are fixedly connected to the expansion bin 12 and the fixed bin 11, respectively. Preferably, the number of the telescopic slide rails 9 is two, which are symmetrically arranged at the lower end of the expansion bin 12. The telescopic slide rail 9 improves the stability of the expansion bin 12 when sliding, and at the same time limits the expansion bin 12 in the horizontal direction to avoid lateral shaking of the expansion bin 12.

[0041] In another technical solution, a polytetrafluoroethylene slide plate is fixedly provided at the bottom of the expansion chamber 12, and the polytetrafluoroethylene slide plate is used to reduce the resistance of the expansion chamber 12 when sliding.

[0042] In another technical solution, Figure 2 As shown, a leg 10 is provided on the side of the expansion chamber 12 away from the fixed chamber 11, and the leg 10 is a retractable structure. The leg 10 is used to support the expansion chamber 12 after the expansion chamber 12 extends out of the fixed chamber 11, so as to ensure the stability of the operating room 1. By adjusting the length of the leg 10, it can adapt to uneven roads.

[0043] Furthermore, if Figure 3 and Figure 4 As shown, the expansion drive device includes a drive motor 13 and a T-type differential 14 fixedly arranged in the expansion chamber 12. The T-type differential 14 has an 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. One output end of the T-type differential 14 is fixedly connected to a gear 15, and the other output end is fixedly connected to a roller. A rack meshing with the gear 15 is arranged on the inner wall of the fixed chamber 11 along the sliding direction of the expansion chamber 12. The drive motor 13 and the T-type differential 14 simultaneously drive the gear 15 and the roller to rotate, and through the cooperation of the gear 15 and the rack, the expansion chamber 12 is driven to slide relative to the fixed chamber 11.

[0044] One end of the support leg 10 is hinged to the side wall of the expansion bin 12, and the other end is fixedly connected with a retracting rope 17; the retracting rope 17 passes through the side wall of the expansion bin 12 and is wound around the drum. The retracting rope 17 is retracted and released by the rotation of the drum, thereby realizing the retraction and release of the support leg 10. That is, when the expansion bin 12 is extended, the retracting rope 17 is slowly lowered at the same time. At this time, the support leg 10 rotates downward around the hinge with the expansion bin under the action of gravity until it is vertically supported on the ground. When the expansion bin 12 is retracted, the retracting rope 17 is rewound to drive the support leg 10 to rotate upward around the hinge with the expansion bin until it fits with the side wall of the expansion bin 12.

[0045] Furthermore, the drum includes a large diameter section 16 and a small diameter section 18 arranged coaxially, the retractable rope 17 is wound around the large diameter section 16; a traction rope 19 is wound around the small diameter section 18, and the retractable 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 bin 11. Considering that the extended part of the expansion bin 12 is not supported during its extension, it will deflect downward under the action of gravity, thereby increasing the torque between the telescopic guide rail 9 and the gear 15 and the rack, and causing a safety hazard due to increased wear after a long time, the traction rope 19 is fixedly connected to the inner top of the fixed bin 11 to provide traction from above, thereby improving the stability of the expansion bin 12 during its extension. The retractable rope 17 and the traction rope 19 are wound in opposite directions on the drum, thereby enabling the retractable rope 17 and the traction rope 19 to be loosened or tightened at the same time when the drum rotates, thereby satisfying the sliding requirements of the expansion bin 12. And by setting the roller to have a large diameter section 16 and a small diameter section 18, the problem of inconsistent travel of the retractable rope 17 and the traction rope 19 is solved. When in use, the roller is supported by a base 20 installed on the top of the expansion chamber 12, and bearing seats 21 are provided on both sides of the base 20 to provide support with both ends of the roller. Preferably, a connecting plate 22 is provided on the inner top of the fixed chamber 11 to keep the traction rope 19 and the connecting section of the fixed chamber 11 level.

[0046] like Figures 2 to 4 As shown, the supporting legs 10 and the expansion driving device are both provided in pairs, and the two are provided in a one-to-one correspondence.

[0047] Furthermore, if Figure 5As shown, the rack includes an upper rack 23 and a lower rack 25 which are arranged opposite to each other, and the two ends of the upper rack 23 and the lower rack 25 are connected by a vertical rod 24. The vertical rods 14 at both ends constitute the limit of the expansion bin 12. Preferably, proximity switches are respectively arranged at both ends of the rack near the vertical rods 24. The proximity switches are connected to the controller to control the opening and closing of the drive motor 13 through the controller, and can also be directly connected to the alarm device to remind that the expansion bin 12 is close to the limit position.

[0048] In another technical solution, a seat 7 is provided in 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 adopt a conventional sliding connection structure to achieve sliding at the inner bottom of the fixed compartment 11. When the expansion compartment 12 is extended, the seat 7 can be slid backward to release the leg space of the staff and alleviate the internal space tension.

[0049] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
