Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe transverse pipe pushing mechanism. Background Art

[0002] A steel pipe has a hollow cross-section and its length is much greater than its diameter or circumference. According to the material, it is divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes. In the production and processing process of the steel pipes used in oil wells, the following disadvantages exist:

[0003] The existing oil pipe conveying mechanisms are theoretically designed with the axis of the oil pipe parallel to the center line of the roller conveying line. While the rollers support the oil pipe and the rollers rotate, they drive the oil pipe to move forward along the rotation direction. When the center lines of the rollers on the conveying line are consistent, the oil pipe is straight, and the two are parallel, the oil pipe is in contact with the rollers. If the oil pipe is bent or twisted, its axis cannot be parallel to the center line of the rollers, and the middle or part of the oil pipe section is suspended. The oil pipe cannot be in contact with the rollers, the rollers rotate idly, the oil pipe does not move, and the production line stops. In this case, it is all solved by manual external intervention methods such as using crowbars and pulling ropes, which is labor-intensive, dangerous, time-consuming and laborious, and affects the operation of the production line. Therefore, the utility model proposes a steel pipe transverse pipe pushing mechanism. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a steel pipe transverse pipe pushing mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A steel pipe transverse pipe pushing mechanism, including a track and a guide rod. A first cylinder and a second cylinder are arranged inside the track. The cylinder body of the first cylinder is fixedly connected to the inner wall of the track. The telescopic rod of the first cylinder is fixedly connected to the cylinder body of the second cylinder. The telescopic rod of the second cylinder is fixedly connected with a push rod. The track is fixedly installed on one side of the oil pipe conveying line. The guide rod is fixedly installed above the oil pipe and on the extension line of the movement of the push rod.

[0006] Further, a first pulley is installed on the outer side wall of the cylinder body of the second cylinder, and the first pulley is slidably connected to the track.

[0007] Further, a guide sleeve is fixedly connected to the outer wall of the track near one end of the push rod. The push rod passes through the guide sleeve and is slidably connected to the guide sleeve.

[0008] Further, one end of the push rod close to the oil pipe is designed to be conical.

[0009] Further, a pulley seat is fixedly connected to the surface of one end of the push rod close to the oil pipe, and a second pulley is installed at the top of the pulley seat. The second pulley is slidably connected to the guide rod.

[0010] Advantages of the present utility model:

[0011] When the present utility model is in use, for a kind of steel pipe transverse pipe-pulling mechanism, a first cylinder, a second cylinder, a track, a first pulley, a push rod, a guide sleeve, a pulley seat and a guide rod are provided. When a stop fault occurs in the oil pipe, first suspend the operation of the equipment, manually control the first cylinder and the second cylinder to extend electrically, the cylinder drives the push rod to move, thereby using the push rod to push the oil pipe axially for a certain distance, and then restart the processing equipment, thus completing the troubleshooting. There is no need for on-site manual operation, the troubleshooting time is short, the effect is good, and the production line operation efficiency is high. Description of the drawings

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0017] As Figure 1 shown, it relates to a steel pipe transverse pipe-pulling mechanism, including a track 3 and a guide rod 8. A first cylinder 1 and a second cylinder 2 are arranged inside the track 3. The cylinder body of the first cylinder 1 is fixedly connected to the inner wall of the track 3, the telescopic rod of the first cylinder 1 is fixedly connected to the cylinder body of the second cylinder 2, the telescopic rod of the second cylinder 2 is fixedly connected with a push rod 5. The track 3 is fixedly installed on one side of the oil pipe 9 conveying line, and the guide rod 8 is fixedly installed above the oil pipe 9 and on the extension line of the movement of the push rod 5.

[0018] In this embodiment, both the first cylinder 1 and the second cylinder 2 are controlled to operate by an externally connected controller.

[0019] As Figure 1 shown, a first pulley 4 is installed on the outer wall of the cylinder body of the second cylinder 2, and the first pulley 4 is slidably connected to the track 3.

[0020] When the first cylinder 1 pushes the second cylinder 2 to move within the track 3, the first pulley 4 can play a role in guiding and stabilizing the second cylinder 2.

[0021] As Figure 1 shown, a guide sleeve 6 is fixedly connected to the outer wall of one end of the track 3 close to the push rod 5. The push rod 5 passes through the guide sleeve 6 and is slidably connected to the guide sleeve 6.

[0022] When the second cylinder 2 extends to drive the push rod 5 to move, the guide sleeve 6 can play a guiding role in the movement of the push rod 5, making the movement of the push rod 5 more stable.

[0023] As Figure 1 shown, one end of the push rod 5 close to the oil pipe 9 is designed to be conical. When the oil pipe 9 is inclined, after the push rod 5 moves to push the oil pipe 9, it is convenient to center the oil pipe 9.

[0024] As Figure 1 shown, a pulley seat 7 is fixedly connected to the surface of one end of the push rod 5 close to the oil pipe 9, and a second pulley is installed at the top of the pulley seat 7. The second pulley is slidably connected to the guide rod 8.

[0025] The pulley seat 7 will move along the guide rod 8, so that one end of the push rod 5 far from the telescopic rod of the second cylinder 2 can stably move along the guide rod 8, thereby pushing the oil pipe 9.

[0026] Working principle: When a stop failure occurs in the oil pipe 9, manually control the conveying equipment to stop running, then first start the first cylinder 1 to extend, drive the second cylinder 2 to move within the track 3, and then start the second cylinder 2 to extend, drive the push rod 5 to move. The push rod 5 will move under the guidance of the guide sleeve 6 and the guide rod 8, and use the push rod 5 to push the oil pipe 9 to move, so that the oil pipe 9 moves a certain distance. Finally, start the conveying equipment to continue running.
