[0026] The specific structure includes: telescopic support mechanism, follow-up mechanism, pushing mechanism.

[0027] (1) telescopic support mechanism

[0028] The telescopic support mechanism includes two horizontally arranged fixed bed rails 1, the fixed bed rails 1 extend along the width direction of the workover truck and are installed at the edge position of one side of the workover truck, the slide 2 extending in the same direction as the fixed bed rails 1 is slidably connected to the top of the fixed bed rails 1, and the bearing seat 3 is fixed to the top of one end of the slide 2. When installing, the bearing seat 3 is arranged at the end away from the chassis, that is, the bearing seat 3 is located at the edge position of the chassis, when the sliding stroke of the slide 2 is started, the bearing seat 3 can be pushed out to the outside of the chassis, so that the whole mechanism is suspended, thereby protruding the vehicle body, facilitating the lifting of the oil pipe on the ground below. At the same time, after the operation is completed, it is retracted to the side of the chassis, realizing the whole non-overwidth (vehicle width), convenient vehicle movement, and efficient follow-up operation.

[0029] In terms of power, hydraulic power can be used, a pushing oil cylinder is installed at the end of the fixed bed rail 1 away from the bearing seat 3, the pushing cylinder rod is telescopically connected to the end of the pushing oil cylinder close to the bearing seat 3, and the end of the pushing cylinder rod is fixed on the slide 2, so as to realize the control of the sliding stroke of the slide 2, so that the slide 2 protrudes from the workover truck body or is retracted within the range of the chassis of the workover truck.

[0030] The support column 4 is arranged on the bearing seat 3, and two fixed lying rails 1 are arranged on the basis, the support column 4 is vertically arranged, one of the support columns is arranged near the vehicle head, and the other support column is arranged near the well mouth operation of the vehicle tail, thereby forming a support structure which can be extended and retracted relative to the vehicle body.

[0031] (2) Following mechanism

[0032] The support seat 5, the groove frame 8 and the reinforcing frame 9 are arranged.

[0033] The bottom of the groove frame 8 is arranged on the top end of the support seat 5, the groove frame 8 is horizontally arranged and vertically arranged relative to the fixed lying rail 1, and therefore, after being arranged on the vehicle body, the groove frame 8 can correspond to the length direction of the vehicle body. The groove frame 8 is a component for horizontally supporting the oil pipe, and a V-shaped groove is arranged on the top of the groove frame 8, which is used for positioning and supporting the oil pipe through the V-shaped structure.

[0034] Because the oil pipe needs to be moved horizontally to the well mouth of the vehicle tail on the groove frame 8, the weight of the oil pipe will be mainly transferred to the support column 4 near the vehicle tail. Therefore, in order to improve the stability of the support, the reinforcing frame 9 is arranged on both sides of the support column 4 near the vehicle tail, the reinforcing frame 9 is a right triangle truss arranged symmetrically, the right angle of the reinforcing frame 9 corresponds to the top end of the support column 4, the top side of the right angle of the reinforcing frame 9 is arranged in parallel with the bottom side of the groove frame 8, the vertical side of the right angle of the reinforcing frame 9 is fixed on both sides of the support column 4, and the support seat 5 is arranged on the top end of the support column 4 and the end of the reinforcing frame 9 away from the support column 4, so that the support column 4 and the reinforcing frame 9 are respectively arranged in cooperation with the groove frame 8 through the support seat 5, and the specific structure is as follows:

[0035] The support seat 5 is a mounting member for supporting the groove frame 8 and guiding the movement of the groove frame 8, the bottom of the support seat 5 is arranged on the top end of the support column 4 through a bolt assembly, or is arranged on the top side of the reinforcing frame 9 away from the support column 4.

[0036] The top of the support seat 5 is rotatably arranged with a guide pulley 6, and the axial direction of the guide pulley 6 is horizontal and vertical relative to the length direction of the groove frame 8.

[0037] A plurality of strip-shaped openings 10 are arranged on the bottom of the groove frame 8 and extend in the same direction as the length of the groove frame 8, and the guide pulley 6 penetrates through the corresponding strip-shaped opening 10 and is matched with the strip-shaped opening 10. The outer end or both ends of the guide pulley 6 are provided with a circular baffle 7, so that the guide pulley 6 is in an I-shaped structure. The diameter of the guide pulley 6 is adapted to the width of the strip-shaped opening 10, and the baffle 7 is larger than the width of the strip-shaped opening 10. Therefore, based on the limiting of the baffle 7 at both ends of the guide pulley 6, the groove frame 8 is constrained on the top of the support, and has a front and rear follow-up stroke corresponding to the length direction of the groove frame 8 relative to the support. When the pipe head (the pipe head is located at the tail of the vehicle) is hoisted, the other end of the oil pipe falls on the V-shaped groove of the groove frame 8, and most of the gravity of the oil pipe is supported on the groove frame 8 by the bottom end thereof. As the oil pipe is gradually hoisted to be vertical, the bottom end of the oil pipe is pulled towards the wellhead, and the guide pulley 6 is followed to realize the adaptation of the position change of the supporting bottom end of the oil pipe, so as to avoid damage to the oil pipe caused by pulling, and the oil pipe is constrained by the V-shaped groove, which facilitates the hoisting positioning and hoisting guidance, and has high safety, and the auxiliary hoisting is more smooth.

[0038] The follow-up process can be automatically followed based on the gravity of the oil pipe, or power can be added for assistance. The reset after follow-up can be manually pushed or assisted by power. If power is used, a follow-up gear driven by a motor can be installed on the upper part of the support column 4 or the reinforcing frame 9 which can rotate, and a follow-up rack matched with the gear is installed on the bottom of the groove frame 8. The front and rear follow-up positions of the groove frame 8 are changed by driving the follow-up gear by the motor.

[0039] (3) Pushing mechanism

[0040] A pushing oil cylinder 12 and a pushing cylinder rod 13 are installed at one end of the groove frame 8 close to the head of the vehicle in a telescopic matching mode. A tail frame 11 is fixed at the end of the groove frame 8 away from the reinforcing frame 9. The pushing oil cylinder 12 is fixed on the tail frame 11 and supported by the tail frame 11. The pushing oil cylinder 12 can be a multi-stage telescopic oil cylinder. The pushing cylinder rod 13 is horizontally matched with the pushing oil cylinder 12 close to the groove frame 8. The end of the pushing cylinder rod 13 is provided with a pushing block 14. The pushing block 14 is located in the V-shaped groove. The oil pipe in the V-shaped groove is pushed towards the hoisting direction based on the telescopic mode, so that the pipe head clamp is exposed outside the V-shaped groove, facilitating the grasping and hoisting operation, realizing the feeding in place, and facilitating the picking of the hoisting operation.

[0041] Based on the above structure, the action cooperation of the mechanism in cooperation with the hoisting operation is as follows:

[0042] After the oil pipe is placed on the groove frame 8, the pushing block 14 at the tail end of the groove frame 8 pushes towards the wellhead, and the pipe head clamp of the oil pipe is pushed forward to be exposed outside the V-shaped groove, facilitating the grasping and hoisting operation.

[0043] After the tubing coupling is started to be hoisted, the groove frame 8 continues to support the bottom end of the tubing, and the whole groove frame 8 moves along with the tail wellhead direction, thereby assisting the horizontal delivery of the tubing to the derrick direction, and stabilizing the hoisting process.

[0044] After the operation is completed, the groove frame 8 and the support column 4 are withdrawn on one side of the workover truck, so that the whole body is not wider than the width, facilitating the walking with the truck, and the operation of collecting and unfolding the truck is automatically completed, without manual installation and without occupying the ground space.
