Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted workover rigs, and more specifically, to a vehicle-mounted workover rig operating room with adjustable space. Background Art

[0002] The driller's cabin, typically installed on the left rear side of the vehicle's platform for minor repairs, is often paired with a driller's control box located at the derrick's inverted triangle, with the driller operating from outside. During operations, the operator's view of the wellhead from the driller's cabin is obscured by the nearby derrick's inverted triangle, the rear support, and the wellhead operating tools. Operating the driller's cabin from outside creates a poor working environment, high intensity, and high fatigue, compromising operational safety. Furthermore, three additional operators are required to perform the workover, creating inconvenience and potentially posing safety risks. To address this issue, existing techniques typically designate the driller's cabin, originally fixed to the rear of the vehicle, as a rotatable structure. The cabin is mounted on a rotating bracket, with a telescopic cylinder installed between the inside of the bracket and the main frame beam. The cylinder's inlet and outlet oil lines are connected to the main vehicle's oil lines. When the equipment arrives at the well site for operation, the telescopic cylinder is operated to deploy the rotating bracket, adjust it to the desired angle, and then secure it. The driller's cabin's rotation angle is then adjusted using a cylinder below the cabin, allowing the operator in the cabin to obtain the optimal viewing angle for the workover operation. During transportation, the cabin, along with the rotating bracket, is retracted into the main vehicle and locked to the frame for transport. However, due to the constraints of road transport, the space reserved for the driller's cabin is limited. The cabin, constrained by the top mast, surrounding lifting cylinders, and its width, is only large enough for a small operator. Extended operation can be difficult, and prolonged operation can easily lead to fatigue, compromising operator comfort and safety. Utility Model Content

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0024] 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 "horizontal", "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 to the present invention.

[0025] like Figures 1 to 4 As shown, the utility model provides a space-adjustable vehicle-mounted workover rig operating room, comprising:

[0026] The operating room 1 includes a fixed compartment 11 and an expansion compartment 12. An operating table 5 and a seat 7 are sequentially arranged on one side of the fixed compartment 11, and an opening is provided on the other side thereof to match the expansion compartment 12. The inner bottom of the fixed compartment 11 is provided with seat rails along which the seat 7 can slide to move closer to or away from the operating table 5. The expansion compartment 12 is slidably arranged in the opening of the fixed compartment 11.

[0027] a driving device, which is disposed in the operating chamber 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;

[0028] The bracket 4 has one end rotatably connected to the tailstock 2 of the vehicle-mounted workover rig via the first rotary cylinder 3 , and the other end rotatably connected to the bottom of the fixed bin 11 via the second rotary cylinder 6 .

[0029] 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 the appropriate 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; after the above adjustment is 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 driving device to expand the internal space of the operating room 1, providing the operator with a more comfortable working space to ensure work efficiency and safety. After the expansion compartment 12 is extended, the space of the operating room 1 is expanded. At this time, the position of the seat 7 can be adjusted to move a certain distance away from the operating table 5, so that the staff's activity space during work is more spacious, improving operational comfort and safety. A conventional slide rail and embedded slider structure can be used between the seat guide rail and the seat, and the slider and the slide rail are fixed by a limit pin. In actual use, a heating and cooling air conditioner can be installed in the expansion compartment 12. When the expansion compartment 12 is deployed, the heating and cooling air conditioner moves back, not occupying the internal operating space, while improving the working environment in the operating room 1. An explosion-proof sight hole lamp 15 is provided on the outside of the fixed compartment 11 at one end close to the operating table 5 for illuminating the weight indicator.

[0030] In another technical solution, Figure 3 As shown, the inner bottom of the fixed compartment 11 is provided with multiple sets of rollers 16 near the opening, and the bottom surface of the expansion compartment 12 near the center of the fixed compartment 11 extends outward to form an extension section. The rollers 16 reduce the resistance of the expansion compartment 12 when sliding relative to the fixed compartment 11. The extension section of the bottom surface of the expansion compartment 12 ensures that the main body of the expansion compartment 12 does not separate from the rollers even after it is fully extended from the fixed compartment 11, thereby facilitating the subsequent retraction of the expansion compartment 12.

[0031] In another technical solution, Figure 3 As shown, the top surface of the expansion chamber 12 is a slope that slopes downward from the inside of the fixed chamber 12 to the outside, so as to prevent rainwater from flowing along the top surface of the expansion chamber 12 to the fixed chamber 11 when it rains. Preferably, a foldable rain shelter is provided above the opening of the fixed chamber 11.

[0032] In another technical solution, Figure 3 As shown, a sealing rubber strip 17 is provided on the periphery of the side of the expansion chamber 12 facing away from the fixed chamber 11. When the expansion chamber 12 is completely retracted into the interior of the fixed chamber 11, the sealing rubber strip 17 seals the joint between the fixed chamber 11 and the expansion chamber 12.

[0033] In another technical solution, the expansion chamber 12 is a box structure composed of five panels with one side open, and the open side faces the fixed chamber; the panel includes two layers of panels and a frame 121 sandwiched between the two layers of panels, such as Figure 4 As shown, the skeleton 121 is a rectangular frame composed of four aluminum tubes, and square wood is arranged inside the aluminum tubes. The slide 121 increases the overall strength of the expansion chamber 12, and the square wood can increase the nail holding force of the expansion chamber 12 during assembly.

[0034] In another technical solution, the driving device includes a driving motor, a gear, and a rack 9 that cooperates with the gear; the driving motor is fixedly mounted on the side wall of the fixed bin 11, and its output end is coaxially fixedly connected to the gear, and the rack is fixedly arranged on the side wall of the expansion bin 12. The driving motor can be a micro motor that meets the driving load. The driving motor is used to drive the gear to rotate, and then drive the expansion bin 12 to extend from the rear end of the fixed bin 11 or retract to the fixed bin 11 through the rack 9. Preferably, two groups of driving devices are provided on both sides of the expansion bin 12, and work synchronously. Furthermore, the driving device can also use a conventional hydraulic cylinder, an electric push rod or an electric telescopic guide rail, which is fixedly arranged on both sides of the bottom or top of the fixed bin 11, and the movable end is hinged to the expansion bin 12. The driving devices on both sides work synchronously to drive the extension and retraction of the expansion bin 12.

[0035] In another technical solution, the bracket 4 includes a fixed portion 41, a movable portion 42, and a telescopic cylinder 8; one end of the fixed portion 41 is rotatably connected to the tail seat 2, and the other end is slidably connected to one end of the movable portion 42, and the other end of the movable portion 42 is rotatably connected to the bottom of the fixed bin 11; the two ends of the telescopic cylinder 8 are hinged to the fixed portion 41 and the movable portion 42, respectively. The first rotating cylinder 3 is fixedly arranged on the tail seat 2, and the rotating shaft of the first rotating cylinder 3 is fixedly connected to the fixed portion 41 to drive the bracket 4 to rotate relative to the tail seat 2; the second rotating cylinder 6 is fixedly arranged on the movable portion 42, and the rotating shaft of the second rotating 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. The length of the bracket 4 is adjusted by the telescopic cylinder 8 to keep the operating room 1 away from the explosion-proof area to ensure personal safety.

[0036] In another technical solution, at least two legs 10 are detachably connected to the side of the expansion chamber 12 facing away from the fixed chamber 11. These legs 10 are retractable. These legs 10 support the expansion chamber 12 after it extends out of the fixed chamber 11, ensuring the stability of the operating room 1. The length of the legs 10 can be adjusted to accommodate uneven road surfaces. These legs 10 can utilize a conventional telescopic structure combining a screw and a sleeve.

[0037] In another technical solution, observation windows 14 are provided on the top surface of the fixed chamber 11, on one end near the operating platform 5, and on the sidewalls on both sides of the operating platform 5. The observation window 14 on one sidewall is a sliding glass window, while the other observation windows 14 are fixed glass windows. Preferably, the top surface of the fixed chamber 11 and the glass of the front observation windows 14 are integral curved glass, and the front glass is tilted and extends to the top, making it easier for the driller to observe the working conditions at the top.

[0038] Furthermore, a protective fence 13 is installed on the top surface of the fixed chamber 11 and the outside of the observation window 14 on one end close to the operating table to provide safety protection for the driller operator during operation; preferably, the protective fence 13 adopts a wholly detachable structure.

[0039] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, 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 illustrations shown and described herein.
