Description

Technical Field

[0001] The utility model relates to the technical field of automated machinery, in particular to a small-scale automated well repair operation device. Background Art

[0002] The function of the automated well repairing device is to improve production efficiency and reduce the labor intensity of well repair workers in oilfield oil and water well repairing operations. It can complete the work through remote control or autonomous operation, reducing manpower input and work risks. However, when the existing automated well repairing device is performing well repairing operations, the work of pulling and lowering the oil pipe, connecting the oil pipe, and breaking the buckle up and down requires manual operation by the well repair workers, which has high labor intensity and low work efficiency.

[0003] In order to deal with the above problems, the existing patent with announcement number CN215369742U proposes a workover rig with integrated automated wellhead operation device. The device places the tubing rack next to the wellhead, drives the support arm to open through the flipping hydraulic cylinder, so that it reaches the bottom of the tubing on the tubing rack, adjusts the luffing arm by controlling the luffing hydraulic cylinder, and grabs the tubing by grabbing the pipe. Finally, the flipping hydraulic cylinder is operated to adjust the luffing arm from the horizontal state to the vertical state, and drives the tubing to the preset position and places the tubing in the power elevator. Then the position is adjusted by the power tubing clamp, and the tubing lowered by the traveling block hook enters the power tubing clamp and is clamped. The automatic tubing grabbing and delivering manipulator clamps and moves the next tubing, and then the operator can buckle the tubing in the clamp in the power tubing clamp and the tubing in the clamp in the power elevator, and then the tubing lowering work can be completed.

[0004] However, although the well repair rig of the above-mentioned integrated automated wellhead operation device can clamp the oil pipe by grabbing the grabbing hand, and then flip it by the flipping cylinder and place it in the power elevator, and perform the pipe lowering work by the power oil pipe clamp, after the automatic oil pipe grabbing and delivering manipulator of the well repair rig of the integrated automated wellhead operation device grabs the oil pipe, the staff needs to move the next oil pipe to the clamping position of the oil pipe rack to facilitate the automatic oil pipe grabbing and delivering manipulator to clamp the oil pipe, resulting in a clamping gap of the automatic oil pipe grabbing and delivering manipulator, thereby reducing the construction efficiency, and when the staff moves the oil pipe, the position is too close to the automatic oil pipe grabbing and delivering manipulator, which is easy to affect the life safety of the staff. Therefore, the present application provides a minor automated well repair operation device to meet the needs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a small-scale automated well repair operation device.

[0006] The technical problem to be solved by the utility model is to provide a minor repair automatic well repair operation device to solve the problem that the existing minor repair automatic well repair operation device needs to manually carry and install pipelines during well repair work, resulting in low efficiency.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] Minor repair automated workover equipment, including:

[0009] A base, the top of which is provided with a control mechanism, a fixing part, a conveying device, a column supporting the conveying device, and a motor driving the conveying device;

[0010] A telescopic mechanism is movably connected to the fixed part through a hinge part, and the fixed part is provided with a rotating mechanism for driving the telescopic mechanism to rotate along the fixed part. The driving end of the telescopic mechanism is provided with a connecting part, and the connecting part is provided with a connecting plate, and the connecting plate is provided with a clamping mechanism, and the connecting part is provided with a rotating mechanism 2 for driving the connecting plate to rotate along the connecting part, and the clamping end of the clamping mechanism faces the unloading end of the conveying device.

[0011] Preferably, the connecting plate is connected to the connecting portion via a supporting plate.

[0012] Preferably, a baffle plate 1 is provided between the clamping mechanism and the unloading end of the conveying device, and a baffle plate 2 is provided at one end of the clamping mechanism opposite to the baffle plate 1.

[0013] Preferably, the sides of baffle plate 1 and baffle plate 2 facing the clamping mechanism are inclined surfaces, and the height of baffle plate 2 is greater than the height of baffle plate 1.

[0014] Preferably, the clamping mechanism is a plurality of groups, and is arranged in parallel on the connecting plate, and the clamping mechanism comprises:

[0015] A fixing member connected to the connecting plate, wherein the fixing member is a hollow structure, wherein a movable plate and a telescopic mechanism 2 for driving the movable plate to slide along the fixing member are slidably arranged inside the fixing member;

[0016] The clamping claws are arranged opposite to each other and are movably connected to an end of the fixing member away from the connecting plate through a hinge member 4;

[0017] The movable member has a first end movably connected to the clamping claw through a second hinge, and a second end of the movable member is movably connected to the movable plate through a third hinge.

[0018] Preferably, the fixing member is provided with a sliding groove for the movable plate to slide.

[0019] Compared with the prior art, the utility model has at least the following beneficial effects:

[0020] In the above scheme, a control mechanism, a conveying device, a motor, a telescopic mechanism 1, a hinge 1, a rotating mechanism 1, a clamping mechanism, and a rotating mechanism 2 are provided. When the tube body is not transferred, the telescopic mechanism 1 and the clamping mechanism are parallel to the unloading end of the conveying device and are lower than the unloading end of the conveying device. At this time, the clamping end of the clamping mechanism is perpendicular to the unloading end of the conveying device and faces the conveying device. When the tube body needs to be transferred and installed, the conveying device is started by the control mechanism, so that the conveying device discharges the tube body on the conveyor belt along the unloading end of the conveying device. Due to the weight of the tube body, the tube body falls onto the clamping mechanism, so that the clamping mechanism clamps the tube body. Clamp, and then start the rotating mechanism one, so that the rotating mechanism one drives the clamping mechanism to rotate to an angle perpendicular to the base, and then control the height of the clamping mechanism through the telescopic mechanism one, so that the pipe body of the clamping mechanism falls toward the construction point, and the connection work between the pipe bodies is completed. In addition, if the pipe body in a high horizontal direction needs to be secretly turned, the connecting plate can be rotated by the rotating mechanism two, so that the pipe body follows the connecting plate to rotate to the horizontal direction, thereby realizing the horizontal installation of the pipe body. The overall structure is simple, and the automation of the pipe body installation is realized, which solves the problem that the existing small-scale automated well repair operation device needs to manually carry and install the pipeline during the well repair work, resulting in low efficiency.

[0021] In the above scheme, baffle one and baffle two are provided. Since baffle one and baffle two both have inclined surfaces, the tube body discharged from the unloading end of the conveying device can accurately slide into the clamping mechanism along the inclined surfaces of baffle one and baffle two. The height of baffle two is higher than that of baffle one, which can avoid the risk of the tube body slipping out along baffle two. The setting of the overall structure can improve the accuracy of the clamping mechanism in clamping the tube body, thereby ensuring the normal operation of the device.

[0022] In the above scheme, a fixed part, a movable plate, a telescopic mechanism 2, a clamping claw, a sliding groove, a fourth hinge part, a movable part, and a third hinge part are provided. When the clamping mechanism clamps the tube body, the telescopic mechanism 2 is started, so that the telescopic mechanism 2 drives the movable plate to slide along the sliding groove of the fixed part toward the clamping claw, so that the movable plate pushes the movable part to move, so that the movable part drives two relatively arranged clamping claws to be relatively close to each other through the fourth hinge part, so as to clamp the tube body. The overall use of multiple sets of linkage mechanisms realizes the automatic clamping of the tube body, saves labor and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specifically, the telescopic mechanism 7 can be an electric lift, a hydraulic lift, etc., the rotating mechanism 29 and the rotating mechanism 5 can be stepping motors, three-phase motors, etc., and the transmission device adopts crawler transmission. In order to realize the automatic clamping of the tube body 12 by the clamping mechanism 13, infrared sensors, pressure sensors, etc. can be installed on the clamping part of the clamping mechanism 13 to realize the automatic clamping of the clamping mechanism 13. In addition, the vertical height between the clamping end of the clamping mechanism 13 and the base 1 is lower than the vertical height between the unloading end of the conveying device 3 and the base 1. At the same time, the clamping end of the clamping structure is facing away from the base 1, so that the tube body 12 can directly fall into the clamping mechanism 13 under the action of gravity.

Due to the gravity of the tube body 12, the tube body 12 falls onto the clamping mechanism 13, so that the clamping mechanism 13 clamps the tube body 12, and then the rotating mechanism 5 is started, so that the rotating mechanism 5 drives the clamping mechanism 13 to rotate to an angle perpendicular to the base 1, and then the height of the clamping mechanism 13 is controlled by the telescopic mechanism 7. , so that the pipe body 12 of the clamping mechanism 13 falls toward the construction point, completing the connection work between the pipe bodies 12. In addition, if the pipe body 12 in the horizontal direction is to be turned secretly, the connecting plate 11 can be rotated by the rotating mechanism 29, so that the pipe body 12 follows the connecting plate 11 to rotate to the horizontal direction, thereby realizing the installation of the pipe body 12 in the horizontal direction. The overall structure is simple, and the automation of the installation of the pipe body 12 is realized, solving the problem that the existing small repair automatic well repair operation device needs to carry and install the pipeline manually during the well repair work, resulting in low efficiency.

[0036] In this embodiment, Figures 1 to 4As shown, the connecting plate 11 is connected to the connecting portion 8 through the supporting plate 10, a baffle 1 4 is provided between the clamping mechanism 13 and the unloading end of the conveying device 3, and a baffle 2 401 is provided at one end of the clamping mechanism 13 opposite to the baffle 1 4. Specifically, the supporting plate 10 enables the connecting portion 8 to better support the connecting plate 11, and the side of the baffle 1 4 and the baffle 2 401 facing the clamping mechanism 13 is an inclined surface, and the height of the baffle 2 401 is greater than the height of the baffle 1 4, so that the tube body 12 discharged from the unloading end of the conveying device 3 can accurately slide into the clamping mechanism 13 along the inclined surfaces of the baffle 1 4 and the baffle 2 401, and the height of the baffle 2 401 is higher than the baffle 1 4, which can avoid the risk of the tube body 12 sliding out along the baffle 2 401, and the setting of the overall structure can improve the accuracy of the clamping mechanism 13 clamping the tube body 12, and ensure the normal operation of the device.

[0037] In this embodiment, Figures 4 to 7 As shown, the clamping mechanism 13 is a plurality of groups, and is arranged in parallel on the connecting plate 11, and the clamping mechanism 13 includes: a fixing member 15, which is connected to the connecting plate 11, the interior of the fixing member 15 is a hollow structure, a movable plate 20 and a telescopic mechanism 21 driving the movable plate 20 to slide along the fixing member 15 are slidably arranged inside the fixing member 15; a clamping jaw 14, which is relatively arranged and movably connected to one end of the fixing member 15 away from the connecting plate 11 through a hinge 4 19; a movable member 17, a first end of which is movably connected to the clamping jaw 14 through a hinge 2 16, and a second end of the movable member 17 is movably connected to the movable plate 20 through a hinge 3 18; a slide groove 151 for the movable plate 20 to slide is provided on the fixing member 15. Specifically, when the clamping mechanism 13 clamps the tube body 12, the telescopic mechanism 21 is started, so that the telescopic mechanism 21 drives the movable plate 20 to slide along the slide groove 151 of the fixed part 15 toward the clamping claw 14, so that the movable plate 20 pushes the movable part 17 to move, so that the movable part 17 drives the two oppositely arranged clamping claws 14 to be relatively close to each other through the hinge part 19, so as to clamp the tube body 12. The overall use of multiple sets of linkage mechanisms realizes the automatic clamping of the tube body 12, saves labor and improves work efficiency.

When the tube body 12 is not transferred, the telescopic mechanism 7 and the clamping mechanism 13 are parallel to the unloading end of the conveying device 3 and are lower than the unloading end of the conveying device 3. At this time, the clamping end of the clamping mechanism 13 is perpendicular to the unloading end of the conveying device 3 and faces the conveying device 3. When the tube body 12 needs to be transferred and installed, the conveying device 3 is started by the control mechanism 101, so that the conveying device 3 discharges the tube body 12 on the conveyor belt along the unloading end of the conveying device 3. Due to the gravity of the tube body 12, the tube body 12 falls onto the clamping mechanism 13, so that the clamping mechanism 13 The holding mechanism 13 clamps the pipe body 12, and then the rotating mechanism 5 is started to drive the clamping mechanism 13 to rotate to an angle perpendicular to the base 1, and then the height of the clamping mechanism 13 is controlled by the telescopic mechanism 7, so that the pipe body 12 of the clamping mechanism 13 falls toward the construction point, completing the connection work between the pipe bodies 12. In addition, if the pipe body 12 in a high horizontal direction needs to be secretly turned, the connecting plate 11 can be rotated by the rotating mechanism 29, so that the pipe body 12 follows the connecting plate 11 to rotate to a horizontal direction, thereby realizing the horizontal installation of the pipe body 12. The overall structure is simple, and the automation of the installation of the pipe body 12 is realized, which solves the problem that the existing small-scale automated well repair operation device needs to manually carry and install the pipeline during the well repair work, resulting in low efficiency.

[0040] By providing baffle 1 4 and baffle 2 401, since baffle 1 4 and baffle 2 401 both have inclined surfaces, the tube body 12 discharged from the unloading end of the conveyor 3 can accurately slide into the clamping mechanism 13 along the inclined surfaces of baffle 1 4 and baffle 2 401. The height of baffle 2 401 is higher than that of baffle 1 4, which can avoid the risk of the tube body 12 sliding out along baffle 2 401. The setting of the overall structure can improve the accuracy of the clamping mechanism 13 in clamping the tube body 12, thereby ensuring the normal operation of the device.
