Description

Technical Field

[0001] The utility model relates to the technical field of well repair operations, in particular to an automatic rod and pipe placing and moving device for well repair operations. Background Art

[0002] Well repair is an important part of the oil industry, and its safety and efficiency directly affect the development and production of oil fields. Well repair refers to the process of transporting oil and gas from underground to the surface through pipelines during the construction of oil wells, or injecting water, gas and other materials into the well to maintain or increase the production capacity of the oil well. In well repair, the placement and movement of sucker rods and oil pipes is a key step, which usually requires a lot of manpower and time.

[0003] Traditional pole and pipe discharge operations usually rely on manual operations, which have the following problems: First, the operation efficiency is low. Manual operation requires a lot of time and manpower, and is easily affected by environmental and human factors; second, there are great safety hazards in the operation. There is a certain degree of danger for personnel working near the wellhead, and accidents are prone to occur; third, the quality of the operation is difficult to guarantee. Manual operation is prone to errors, which affects the quality and stability of the discharge pipe.

[0004] The existing automatic rod placement and transportation device is powered by batteries, which need to be charged frequently and cannot operate continuously for a long time. The existing automatic rod placement and transportation device is designed for specific types or specifications of rods, which leads to limitations in responding to the diverse needs of well repair operations. There are problems such as high failure rate and poor stability, which affect the reliability and continuous operation ability of the device.

[0106] When the rod pipe 6 for well repair operation is put on, the hydraulic cylinder 108 at the fork shear mechanism on one side is pressurized, the support 104 on the pipe laying mechanism 1 is inclined to the ground at a predetermined angle, and the mechanical claw cylinder 308 makes the mechanical claw 309 capture the rod pipe 6 for well repair operation, drive the mechanical claw 309 to rotate, and place the rod pipe 6 for well repair operation at a specified position on the base of the lifting mechanism 3, and then drive the lifting claw 305 on the chain 302 to send the rod pipe 6 for well repair operation from the base of the lifting mechanism 3 to the pipe laying rack through the rotation of the sprocket 306 on the sprocket 306 seat, and the rod pipe 6 for well repair operation is put on in this reciprocating manner.

[0107] When the rod pipe 6 for well repair operation is lowered, the hydraulic cylinder 108 at the fork shear mechanism on the other side is pressurized, and the support member 104 on the pipe laying mechanism 1 is inclined to the ground at a predetermined angle.

Then, the rotation of the sprocket 306 on the sprocket 306 seat drives the lifting claw 305 on the chain 302 to send the sucker rod or oil pipe from the base of the lifting mechanism 3 to the pipe rack, and the process of placing the sucker rod or oil pipe is realized in this reciprocating manner.

[0112] The process of lowering the sucker rod or tubing:

[0113] The hydraulic cylinder 108 at the fork-shear mechanism on the other side is pressurized, and the support member 104 on the pipe arrangement mechanism 1 cooperates with the position fixing pin, so that the support member 104 is inclined to the ground. The position fixing pin has four positions to choose from, and the inclination angle of the support member 104 is selected according to different situations. Figure 2 .

[0114] The rotation of the sprocket 306 on the sprocket 306 seat drives the lifting claw 305 on the chain 302 to send the sucker rod or oil pipe from the pipe rack to the specified position of the base of the lifting mechanism 3, and then the extension and contraction of the mechanical claw cylinder 308 enables the claw hand to grab the sucker rod or oil pipe, and then the motor drives the mechanical arm to rotate to send the sucker rod or oil pipe to the specified position, and then the well repair vehicle performs subsequent work, and the process of lowering the sucker rod or oil pipe is realized in this reciprocating manner.

[0116] In one embodiment, the limiting mechanism 2 includes a lifting seat 201, a limiting seat oblique support 202, a second hydraulic cylinder 203, an outer slide rail 204, a wrapping rubber 205, and a wear strip 206.

The wrapping rubber 205 is installed on the side close to the pipe arrangement mechanism 1, and contacts the sucker rod or the oil pipe to reduce the impact. The lifting and lowering of the outer slide rail 204 ensures that the limiting height of the limiting mechanism is always consistent with the height of the oil pipe being transported, preventing the oil pipe from falling off the oil pipe rack.

[0117] In one embodiment, during the process of raising the sucker rod or the oil pipe, the lifting mechanism 3 sends the sucker rod or the oil pipe to the specified position of the base through the mechanical claw 309, and then the sprocket 306 mechanism drives the lifting claw 305 to send the sucker rod or the oil pipe to the pipe arrangement mechanism 1; during the process of lowering the sucker rod or the oil pipe, the sprocket 306 mechanism drives the lifting claw 305 to send the sucker rod or the oil pipe to the specified position. The lifting mechanism 3 includes a second base 301, a sprocket 306, a chain 302, a straightening rail 303, a chain link 304, a sprocket shaft, a bushing 311, a bearing seat, a lifting claw 305, and a mechanical claw 309. The main structure of the lifting mechanism 3 is a second base 301, and the second base 301 is equipped with bearing seats on the upper and lower sides. The sprocket 306 is installed in the middle of the sprocket shaft, and the sprocket shaft is installed in the middle of the bearing seat. The outer sleeve is sleeved with a shaft sleeve 311, which axially positions the bearing and the sprocket. The chain 302 is installed on the two sprockets 306; the lifting claw 305 is fixed on the chain link 304, the chain link 304 is fixed on the chain 302, and the straightening track 303 is welded on the base; the mechanical claw 309 is fixed on the base through the bearing seat. The lifting claw 305 is fixed on the chain link 304, and the left end of the bottom of the lifting claw 305 cooperates with the straightening track 303 through a rolling bearing, which limits the lifting claw 305 to move up and down and prevents the lifting claw 305 from shaking back and forth, that is, the straightening track 303 and the lifting claw 305 have a limiting effect. The lifting claws 305 are evenly installed and fixed on the chain links. When the sprocket rotates, the chain drives the lifting claws to move along the circumference of the sprocket. When the lifting claws are located close to the oil pipe side, they run from bottom to top. When they run to the bottom of the oil pipe and contact the oil pipe, the oil pipe automatically slides into the inside of the lifting claws, driving the oil pipe to separate from the support frame. When the oil pipe is driven to the upper part of the lifting mechanism, the oil pipe slides into the upper V-groove and separates from the lifting claws. The lifting claws run away from the oil pipe side and move downward. After reversing at the bottom, they move upward again to complete the grabbing of the next oil pipe.

[0118] In one embodiment, the limiting mechanism 2 and the fixed limiting mechanism 4 complete the limitation of the position of the sucker rod or the oil pipe, and the fixed limiting mechanism 4 includes a first base 401, a spring pressure plate 404, a spring baffle 402, a spring 403, an oblique support 406, and a protective rubber 405. The first base 401 is used as the main structure, and its bottom surface is fixed to the fixed support base 101 of the pipe arrangement mechanism 1 by bolts; an oblique support is added to the right side of the base to increase the strength; two spring pressure plates 404 are installed in the middle of the first base 401, the spring 403 is sleeved on the spring pressure plate 404, and the spring baffle 402 is sleeved on the right side of the spring pressure plate 404. The spring baffle 402 limits the spring 403 through the shoulder limit, and the protective rubber 405 is installed on the side close to the pipe arrangement mechanism 1, and contacts with the sucker rod or the oil pipe to reduce the impact. On the whole, these mechanisms work together to realize the automatic placement, limiting and movement of the sucker rod or the oil pipe in the up and down process, ensuring the smooth operation of the maintenance process.
