Description

Technical Field

[0001] The invention relates to the technical field of petroleum equipment, in particular to self-propelled petroleum drilling derrick intelligent disassembly and assembly overhead crane lifting equipment. Background Art

[0002] The height of an oil drilling derrick is usually more than 30 to 40 meters. Due to its huge size, it is difficult to transport as a whole. Therefore, it is disassembled into parts for transportation and then assembled on site at the well site. The derrick is generally composed of multiple sections. The traditional assembly method is to use two cranes and a forklift to assemble each section from bottom to top. This method has high safety risks and is likely to cause personal injury and damage to components.

It has the following technical problems during use:

[0004] (1) There is only one support point for the derrick, and the single support method is not stable enough.

[0005] (2) There is a lack of lateral fixing devices for the derrick, which makes it easy for the derrick to slip laterally and cannot suppress high-frequency or violent lateral swings of the derrick.

[0006] (3) It is impossible to monitor the angle and position of the derrick. Summary of the invention

[0007] In order to solve the technical problems existing in the background technology, the present invention provides a self-propelled oil drilling derrick intelligent disassembly and assembly overhead crane lifting equipment, which provides a more reliable support for the derrick and effectively prevents the derrick from shaking.

[0008] The technical solution adopted by the present invention to solve its technical problem is:

[0059] The present invention is further described in detail below with reference to the accompanying drawings.

[0060] like Figure 1 , 2 As shown in Figure 3, the specific structure of the self-propelled oil drilling derrick intelligent disassembly and assembly overhead crane lifting equipment includes a frame 1. A hydraulic station for driving is arranged in the frame 1. The walking device 3 is arranged at the lower end of the frame 1 so as to be liftable. The walking device 3 is symmetrically arranged on both sides of the frame 1, and the walking device 3 adopts a crawler walking mode. The first oil cylinder 2 is arranged in a vertical direction between the frame 1 and the walking device 3, and is used to drive the lifting and lowering of the walking device 3. There are four first oil cylinders 2, and a first oil cylinder 2 is arranged at both ends of the walking device 3 on each side, so as to ensure the stability of the lifting and lowering of the walking device 3.

[0061] The lifting assembly 5 is movably arranged at the upper end of the frame 1. The second oil cylinder 4 is arranged between the frame 1 and the lifting assembly 5, and is used to drive the lifting of the lifting assembly 5. There are two second oil cylinders 4. The two second oil cylinders 4 are located in the middle of the frame 1, and the two second oil cylinders 4 are symmetrically arranged. The connection position between the second oil cylinder 4 and the lifting assembly 5 is located at the center of the lifting assembly 5. Thereby ensuring that the force of the lifting assembly 5 is balanced. The support assembly 6 is swingably arranged at the upper end of the lifting assembly 5. A plurality of support points are formed between the support assembly 6 and the derrick, and the plurality of support points are always supported on the derrick, thereby enhancing the support capacity of the derrick.

[0062] like Figure 4 , 5 As shown, the specific structure of the lifting assembly 5 includes a top frame 51. A guide column 52 is arranged at the lower end of the top frame 51, and the guide column 52 is located at the four corners of the top frame 51. The guide column 52 can be slidably inserted on the frame 1. The guide column 52 can play a guiding role to prevent the top frame 51 from deflecting. A through hole is provided on the guide column 52, and a safety pin can be inserted into the through hole. The safety pin can be supported by the frame 1, thereby limiting the descent of the guide column 52 and playing a role of safety protection. A scale line is also provided on the guide column 52, so that the extension length of the guide column 52 can be displayed, thereby determining the height of the lifting assembly 5. In a specific implementation, the guide column 52 adopts a multi-layer nested structure, thereby further increasing the limit extension distance of the guide column 52.

[0063] The support assembly 6 includes a swing frame 61, which is swingably arranged at the upper end of the top frame 51, and the connection between the swing frame 61 and the top frame 51 is located at the center of the top frame 51. Support rollers 62 are rotatably arranged at both ends of the swing frame 61. In a specific implementation, the support rollers 62 at both ends of the swing frame 61 are symmetrically arranged about the center of the swing frame 61. An encoder 54 is arranged between the swing frame 61 and the top frame 51. The encoder 54 is arranged at the connection between the swing frame 61 and the top frame 51. The main body of the encoder 54 is fixedly connected to the top frame 51, and the rotating shaft of the encoder 54 is fixedly connected to the swing frame 61. The encoder 54 can detect the swing angle of the swing frame 61. Since the swing frame 61 can rotate synchronously with the derrick, the angle change of the derrick can be indirectly monitored by monitoring the angle change of the swing frame 61.

[0064] The top frame 51 is provided with a first buffer block 53, and the support roller 62 can be pressed on the first buffer block 53. The first buffer block 53 can prevent the support roller 62 from colliding with the top frame 51, which may cause the structure to deform and become unstable.

[0065] like Figure 6As shown, a clamping assembly 63 is provided on the support assembly 6. The clamping assembly 63 includes a cross rail 6301, which is provided on the swing frame 61. The cross rail 6301 is located between the support rollers 62 at both ends of the swing frame 61. The cross rail 6301 adopts a square cavity structure. The length direction of the cross rail 6301 is parallel to the length direction of the support roller 62. The slide 6302 is slidably mounted on the cross rail 6301, and the slide 6302 can only slide relative to the cross rail 6301, but cannot rotate relative to the cross rail 6301. There are two slides 6302. The clamping roller 6303 is rotatably provided at the upper end of the slide 6302. The derrick is located between the two clamping rollers 6303. The third oil cylinder 6304 is provided between the two slides 6302. When the third oil cylinder 6304 contracts, the two clamping rollers 6303 can clamp the two sides of the derrick, thereby limiting the lateral position of the derrick to prevent the derrick from falling off. In addition, a displacement sensor 64 is also provided on the swing frame 61. In a specific implementation, the displacement sensor 64 is a laser displacement sensor, which can detect the position of the slide 6302, thereby monitoring the lateral displacement of the derrick to avoid the lifting device losing balance due to excessive deviation of the derrick.

[0066] The second buffer blocks 6305 are arranged at both ends of the cross rail 6301, and the second buffer blocks 6305 are located between the slide 6302 and the swing frame 61. The slide 6302 can be pressed on the second buffer blocks 6305. The second buffer blocks 6305 can prevent the slide 6302 from colliding with the swing frame 61, which may cause the structure to deform and become unstable.

[0067] The third oil cylinder 6304 is a single-acting oil cylinder, and the structure of the third oil cylinder 6304 is specially designed. The specific structure and principle of the third oil cylinder 6304 are as follows:

[0068] The third oil cylinder 6304 is provided with only one oil port. When the oil port pressure increases, the hydraulic oil enters the third oil cylinder 6304 from the oil port, which drives the piston rod of the third oil cylinder 6304 to contract, so that the two clamping rollers 6303 clamp the two sides of the derrick. In addition, a return spring is also provided in the third oil cylinder 6304. When the oil port pressure decreases, the return spring drives the piston rod to extend, the hydraulic oil flows out from the oil port, and the extension of the piston rod causes the clamping rollers 6303 on both sides to move away from the derrick.

[0069] The piston rod of the second oil cylinder 4 is provided with a through hole 41 which runs through from top to bottom. The lower end of the through hole 41 is connected to the cavity of the second oil cylinder 4, and the upper end of the through hole 41 is connected to the oil port of the third oil cylinder 6304 through a one-way valve 6306 and a sequence valve 6307 which are arranged in parallel. The hydraulic oil in the second oil cylinder 4 can enter the third oil cylinder 6304 through the sequence valve 6307. The hydraulic oil in the third oil cylinder 6304 can flow back to the second oil cylinder 4 through the one-way valve 6306. The special oil cylinder structure and pipeline connection design enable the various components to work together. Through a single hydraulic source, the lifting and clamping actions can be controlled in an orderly manner to achieve a linkage effect. This design not only simplifies the structure, but also facilitates operation and maintenance, making the entire system more efficient and reliable.

[0070] like Figure 7 As shown, a closed cavity is provided inside the cross rail 6301, and the cavity is filled with fluid. In a specific implementation, hydraulic oil or lubricating oil can be used. The clamping assembly 63 also includes a slider 6308, which is slidably arranged in the cavity of the cross rail 6301, and the outer periphery of the slider 6308 is in contact with the inner wall of the cavity of the cross rail 6301. An inner hole 6309 is provided on the slider 6308, and the inner hole 6309 passes through the slider 6308 transversely along the length direction of the cross rail 6301. Both sides of the slider 6308 and the inner hole 6309 are filled with fluid. When the slider 6308 slides, the fluid on one side of the slider 6308 will flow to the other side of the slider 6308 through the inner hole 6309. Since the diameter of the inner hole 6309 is small, it will limit the flow of the fluid passing through the slider 6308, so that the slider 6308 can only slide smoothly, but not high-frequency or violent sliding. The first magnet 6310 is disposed on the slider 6308, and the second magnet 6311 is disposed on the slide 6302, and the second magnet 6311 is magnetically matched with the first magnet 6310. The slide 6302 and the slider 6308 can be moved synchronously by the first magnet 6310 and the second magnet 6311. Since the slider 6308 can only slide smoothly, the derrick clamped by the clamping roller 6303 on the slide 6302 can only swing smoothly and slightly, so that the clamping assembly can effectively suppress the high-frequency or violent swing of the derrick in the lateral direction, thereby ensuring the stability and safety of the derrick.

[0071] Specific usage:

[0072] a. Mobile:

[0073] The hydraulic oil in the hydraulic station enters the cavity of the first cylinder 2, the first cylinder 2 extends, the traveling device 3 contacts the ground, the frame 1 is separated from the ground, the traveling device 3 runs, and the traveling device 3 drives the lifting device to move to the working position.

[0074] b. Seated:

[0075] The hydraulic oil in the cavity of the first oil cylinder 2 enters the hydraulic station, the first oil cylinder 2 is shortened, the traveling device 3 is separated from the ground, the frame 1 is in contact with the ground, and the lifting device is reliably fixed to the ground.

[0076] c. Lifting:

[0077] The hydraulic oil in the hydraulic station enters the cavity of the second oil cylinder 4, the second oil cylinder 4 extends, and the lifting assembly 5 rises until the support rollers 62 at both ends of the support assembly 6 are in contact with the lower end surface of the derrick. It should be noted that during the process of the lifting assembly 5 rising, the pressure of the hydraulic oil in the cavity of the second oil cylinder 4 is constant.

[0078] d. Clamping:

[0079] The hydraulic oil in the hydraulic station continues to enter the cavity of the second oil cylinder 4. Since the support rollers 62 at both ends of the support assembly 6 are in contact with the lower end surface of the derrick, the second oil cylinder 4 cannot continue to extend. Therefore, the pressure of the hydraulic oil in the cavity of the second oil cylinder 4 will increase.

[0080] When the pressure of the hydraulic oil in the cavity of the second oil cylinder 4 reaches a certain value, the sequence valve 6307 opens. The hydraulic oil in the cavity of the second oil cylinder 4 enters the cavity of the third oil cylinder 6304 through the through hole 41 and the sequence valve 6307. At this time, the third oil cylinder 6304 contracts, so that the two clamping rollers 6303 clamp the two sides of the derrick.

[0081] The hydraulic oil in the hydraulic station continues to enter the cavity of the second oil cylinder 4. Due to the limitation of the derrick, the third oil cylinder 6304 cannot continue to shrink. The pressure of the hydraulic oil in the second oil cylinder 4 and the third oil cylinder 6304 will further increase. Until the lifting force of the second oil cylinder 4 can lift the derrick, the support roller 62 can completely lift the derrick. While the derrick is lifted by the two support rollers 62, it is also clamped and fixed by the two clamping rollers 6303.

[0082] e.Decline:

[0083] The hydraulic oil in the cavity of the second oil cylinder 4 enters the hydraulic station, the second oil cylinder 4 shortens, the support assembly 6 descends along with the lifting assembly 5, and the derrick also descends synchronously. During this process, the third oil cylinder 6304 is always in a contracted state, and the two clamping rollers 6303 always clamp the two sides of the derrick.

[0084] f. Release:

[0085] When the derrick is lowered to the predetermined position, it is supported by another lifting device and cannot continue to lower. As the hydraulic oil in the cavity of the second oil cylinder 4 continues to enter the hydraulic station, the pressure of the hydraulic oil in the cavity of the second oil cylinder 4 decreases, and the hydraulic oil in the cavity of the third oil cylinder 6304 flows back to the cavity of the second oil cylinder 4 via the one-way valve 6306 and the through hole 41. The return spring drives the piston rod to extend, and the extension of the piston rod causes the clamping rollers 6303 on both sides to move away from the derrick, thereby releasing the clamping of the derrick.

[0086] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
