Description

Technical Field

[0001] This utility model relates to the field of oilfield well workover technology, specifically a foldable height-adaptive vehicle platform. Background Technology

[0002] In oil well workover operations, vehicle-mounted hydraulic workover platforms (commonly known as "powered tongs control panels") are widely used to operate hydraulic tongs for attaching and detaching tubing and drill pipe. There are currently two main types of vehicle-mounted platforms: 1. Sliding rail platform: The platform and hydraulic clamps are slid from the vehicle-mounted position to the wellhead via sliding rails. The disadvantage is that when the required sliding distance is long (such as exceeding the effective stroke of a single sliding rail section), multiple sliding rail sections are required, resulting in a complex structure, reduced rigidity, large space occupation, and cumbersome operation.

[0003] 2. Knuckle boom lift: This type of lift uses a hydraulic folding boom to extend the platform and hydraulic tongs to the wellhead position. Its disadvantage is that the folding boom primarily provides horizontal displacement. When the wellhead height changes, such as between different well sites or during well workover, the height of the hydraulic tongs needs to be adjusted separately, usually through a lifting cylinder or adjusting mechanism additionally installed on the folding boom or platform. This not only increases the complexity and cost of the equipment but also adds to the operational steps and time.

[0004] Therefore, there is an urgent need for a vehicle-mounted well repair platform that is more compact in structure, easier to operate, especially with one-step height adjustment, and can effectively achieve environmentally friendly sewage collection. Utility Model Content

[0005] The purpose of this invention is to provide a foldable, height-adaptive vehicle platform to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable height-adaptive vehicle platform, comprising a support frame fixedly connected to a vehicle, a lifting mechanism fixedly connected to the side of the support frame away from the vehicle, a power folding system disposed on the lifting mechanism, a working platform disposed at the end of the power folding system, a working device including a hydraulic clamp disposed above the working platform, and an independent sludge collection system disposed at the wellhead position. The lifting mechanism includes a lifting frame, the power folding system includes a hydraulic cylinder A and a hydraulic rod A disposed at the output end of the hydraulic cylinder A, a plurality of hydraulic cylinders A are hinged to the lifting frame, the end of the hydraulic rod A away from the hydraulic cylinder A is hinged to the bottom surface of the working platform, and the end of the working platform near the hydraulic cylinder A is hinged to the lifting frame at the position above the hydraulic cylinder A.

[0007] Preferably, the support frame includes a connecting frame fixedly mounted on the vehicle, a plurality of hydraulic cylinders D fixedly mounted at the bottom of the connecting frame, hydraulic rods D fixedly mounted at the output ends of the plurality of hydraulic cylinders D, and a support platform located below the connecting frame and fixedly connected to the plurality of hydraulic rods D.

[0008] Preferably, the connection point between the working platform and the lifting frame is located in the direction closer to the vehicle from the connection point between the hydraulic cylinder A and the lifting frame.

[0009] Preferably, a fixed frame is fixedly installed around the working equipment. The power folding system also includes several connecting plates installed on the working platform, a support arm A hinged to the end of the connecting plate away from the support frame, a support arm B hinged to the end of the connecting plate away from the support arm A, and a support plate hinged to the end of the connecting plate away from the support arm A. The end of the connecting plate away from the vehicle is hinged to the working platform, the end of the support plate away from the connecting plate is hinged to the lifting frame, and the ends of the support arm A and the support arm B away from the connecting plate are respectively hinged to both ends of the fixed frame.

[0010] Preferably, a hydraulic cylinder B is hinged between the support arm A and the support arm B on the connecting plate, and a hydraulic rod B is fixedly provided at the output end of the hydraulic cylinder B. The end of the hydraulic rod B away from the hydraulic cylinder B is hinged to the support arm B.

[0011] Preferably, the lifting mechanism further includes a vertical frame fixedly mounted on the support frame corresponding to both ends of the lifting frame, a base plate fixedly mounted at the bottom of the vertical frame, a hydraulic cylinder C fixedly connected to the top of the base plate, and a hydraulic rod C fixedly mounted at the output end of the hydraulic cylinder C, wherein the end of the hydraulic rod C away from the hydraulic cylinder C is fixedly connected to the lifting frame.

[0012] Preferably, the main structure of the vertical frame is a channel steel, and a number of sliding members are fixedly provided on the side of the lifting frame near the vertical frame, and the sliding members slide in the long groove on the vertical frame.

[0013] Preferably, the working platform has a working port corresponding to the wellhead position, and the independent sewage collection system includes a chuck that is engaged at the inlet position and a sewage collection umbrella that is engaged on the chuck for collecting sewage from the work platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides support and stability for the entire device by setting up a hydraulic cylinder D and controlling the hydraulic cylinder D to drive the hydraulic rod D to move downward. The hydraulic rod D drives the support platform to move downward until it is supported on the ground. When the work site is moved, the hydraulic cylinder D can be controlled to lift the support platform off the ground, which is convenient and quick. This utility model uses a hydraulic cylinder A to drive the hydraulic rod A to retract. As the hydraulic rod A shortens, it rotates towards the oil well around the connection point. At the same time, it drives the working platform to rotate towards the oil well around the connection point until the working platform reaches a horizontal position. At this point, the hydraulic cylinder A is stopped, and the working platform remains stationary in the working position. This invention utilizes a hydraulic cylinder B. Controlling the hydraulic cylinder B causes the hydraulic rod B to push forward, which in turn causes the support arm B to rotate away from the oil well. This, in turn, causes the fixed frame to move away from the oil well. The support arm A at the other end of the fixed frame rotates synchronously with the support arm B. Since the lengths of support arms A and B remain constant, the angle between the fixed frame and the working equipment on it remains unchanged. The working equipment on the fixed frame moves away from the oil well in the horizontal direction. Conversely, when the hydraulic cylinder B retracts the hydraulic rod A, the working equipment moves closer to the oil well in the horizontal direction. After the working platform is deployed, the hydraulic cylinder B can adjust the working equipment and move it to a suitable position. This utility model incorporates a hydraulic cylinder C. When the oil well is too high and the working platform cannot be deployed above it, the hydraulic cylinder C is controlled to move the lifting frame upwards, thereby causing the working platform connected to it to move upwards. The working platform then moves the power folding system and working equipment connected to it upwards until they are positioned above the oil well, facilitating the normal operation of the working equipment.

[0026] Working principle

[0027] The vehicle-mounted platform completes preparations for installation and relocation using a dedicated vehicle. Upon arrival at the designated location, hydraulic cylinder D12 is controlled, driving hydraulic rod D13 downwards. Hydraulic rod D13 then moves support platform 14 downwards until it rests on the ground, providing support and stability for the entire device. Hydraulic cylinder A31 is then driven, causing hydraulic rod A32 to retract. As hydraulic rod A32 shortens, it rotates towards the well around the connection point, simultaneously rotating the working platform 4 towards the well around the connection point until it reaches a horizontal position. At this point, hydraulic cylinder A31 stops, and the working platform 4 remains stationary. The rotation of the working platform 4 causes the hinged connecting plate 38 to move. Connecting plate 38 then moves support arm A33, support arm B34, hydraulic cylinder B35, and support plate 37. Throughout this process, connecting plate 38 remains horizontal and gradually moves onto the working platform 4, while the relative positions of connecting plate 38, support arm A33, support arm B34, hydraulic cylinder B35, and support plate 37 remain unchanged. Hydraulic cylinder B35 is controlled, which drives hydraulic rod B36 to push forward. Hydraulic rod B36 drives support arm B34 to rotate away from the oil well, thereby moving fixed frame 51 away from the oil well. Support arm A33 at the other end of fixed frame 51 rotates synchronously with support arm B34. Since the lengths of support arm A33 and support arm B34 remain unchanged, the angle between fixed frame 51 and the working equipment 5 on it remains unchanged. The working equipment 5 on fixed frame 51 moves away from the oil well in the horizontal direction. Conversely, hydraulic cylinder B35 drives hydraulic rod A32 to retract, which moves the working equipment 5 closer to the oil well in the horizontal direction. When the working platform 4 is unfolded, hydraulic cylinder B35 can adjust the working equipment 5 and move it to a suitable position. When the oil well is too high and the working platform 4 cannot be deployed above the oil well, the hydraulic cylinder C24 is controlled. The hydraulic cylinder C24 drives the lifting frame 21 to move upward, thereby driving the working platform 4 connected to it to move upward. The working platform 4 drives the power folding system 3 and the working equipment 5 connected to it to move upward until it moves above the oil well, which facilitates the normal operation of the working equipment 5. The sliding part 211 moves on the vertical frame 22 to ensure that the lifting frame 21 moves in the vertical direction. The chuck 61 and the sewage collection umbrella 62 are used to receive the sewage from the platform operation and guide it to the collection device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
