Description

Technical Field

[0001] The utility model relates to the field of rust removal devices, in particular to a pipeline rust removal device for oil and gas field surface construction. Background Art

[0002] Oil and gas field surface engineering is a subsystem of the large oil and gas field development and production system, and is an essential link in oil and gas development and production. Oil and gas field surface engineering usually uses oil pipelines for oil transportation. The pipes of oil pipelines are generally steel pipes, which are connected into long-distance pipelines using welding and flange connection devices, and valves are used for opening and closing control and flow regulation. After long-term use of oil pipelines, the surface of the pipelines is prone to rust and corrosion, and it is necessary to carry out rust removal and protection operations on the oil pipelines in a timely manner.

[0003] Chinese patent number CN202323270043.5 discloses a pipeline rust removal device for surface construction of oil and gas fields, including a base plate and a pipeline body, wherein the pipeline body is provided on the top surface of the base plate; a rust removal component, which is provided above the base plate and can remove rust from the outer and inner surfaces of the pipeline body; a fixing component, which is provided on the top surface of the base plate and can fix the position of the pipeline body; and a soft pad, which is provided directly above the pipeline body and can improve the fixing effect of the pipeline body.

[0004] From the above, it can be seen that the rust removal component can be used to remove rust from the outer surface of the pipe body, as well as the inner surface of the pipe body. However, this case still has the following shortcomings: when removing rust from the pipe, due to inconsistent pipe diameter specifications, the existing technology cannot match different pipes accordingly. When the pipe diameter is too large or too small, it is easy for the rust removal device to fail to fully remove rust, resulting in certain limitations in use.

[0005] Therefore, in response to the above problems, a pipeline rust removal device for oil and gas field surface construction is proposed. Utility Model Content

[0011] Preferably, a fixing frame is movably mounted on one side of the mounting frame via a movable limiting mechanism, a connecting plate is movably mounted on one end of the fixing frame, and two driven wheels are movably mounted on the connecting plate.

[0023] See also Figure 1-Figure 5 As shown, a pipeline rust removal device for surface construction in oil and gas fields includes a base 1 and a rust removal adjustment assembly 2. The rust removal adjustment assembly 2 is equipped with a second servo motor 21. A second threaded shaft 22 is fixedly mounted on the output end of the second servo motor 21. A second slider 23 is passed through the second threaded shaft 22 and is threadedly connected thereto. A plurality of second slide rails 24 are movably mounted on the bottom of the second slider 23. A mounting bracket 25 is fixedly mounted on the top of the second slider 23. A second torque motor 26 is fixedly mounted on one side of the mounting bracket 25.

[0024] During operation, the second threaded shaft 22 and the second slider 23 are threadedly engaged with each other, which facilitates the second slider 23 to slide on the second slide rail 24 , thereby adjusting the position.

[0025] Furthermore, the base 1 is mounted with a support plate 11, a support base 12 is fixedly mounted on the top of the support plate 11, a first servo motor 13 is fixedly mounted on the top of the support base 12, a first threaded shaft 14 is fixedly mounted on the output end of the first servo motor 13, and a first slider 15 is fixedly mounted on the first threaded shaft 14;

[0026] During operation, the support plate 11 is used as a whole to carry out load-bearing and fixing, which is helpful to ensure the stability of the top component during operation.

[0027] Furthermore, a placement plate 19 is fixedly mounted on the top of the support plate 11, two first slide rails 17 are movably mounted on the bottom of the first slider 15, a first torque motor 16 is fixedly mounted on the top of the first slider 15, and a fixture 18 is fixedly mounted on the output end of the first torque motor 16;

[0028] During operation, the pipe is placed by installing the placement plate 19, and then one side of the pipe is fixed by the clamp 18, so that the first slider 15 can drive the pipe to move synchronously when it moves.

[0029] Furthermore, a transmission wheel 27 is fixedly mounted on the output end of the second torque motor 26. One side of the transmission wheel 27 is transmission-connected to a frosting belt 28. The other side of the frosting belt 28 is transmission-connected to a plurality of driven wheels 33. The top side of the frosting belt 28 is transmission-connected to an adjusting wheel 37.

[0030] During operation, the second torque motor 26 provides power to rotate the transmission wheel 27 , and under the limitation of the transmission wheel 27 , the driven wheel 33 and the regulating wheel 37 , the abrasive belt 28 rotates to perform rust removal.

[0031] Furthermore, a fixing frame 29 is movably mounted on one side of the mounting frame 25 via a movable limiting mechanism 31. A connecting plate 32 is movably mounted on one end of the fixing frame 29. Two driven wheels 33 are movably mounted on the connecting plate 32.

[0032] During operation, the fixing frame 29 is limited on the mounting frame 25 by the movable limiting mechanism 31 . When the position of the fixing frame 29 needs to be adjusted, the clamping limit of the movable limiting mechanism 31 on the fixing frame 29 is cancelled, so that the fixing frame 29 can move on the mounting frame 25 .

[0033] Furthermore, a hydraulic cylinder 34 is hingedly connected to one side of the fixed frame 29, a piston rod 35 is movably mounted on the output end of the hydraulic cylinder 34, one end of the piston rod 35 is fixedly hingedly connected to a movable arm 36, the other side of the movable arm 36 is movably mounted to the mounting frame 25, and one side of the movable arm 36 is movably mounted to an adjusting wheel 37;

[0034] During operation, when the hydraulic cylinder 34 is driven to extend and retract the piston rod 35 , one end of the piston rod 35 is linked to the movable arm 36 , so that the movable arm 36 moves in a circle with the connection point of the mounting bracket 25 as the axis.

[0035] Working principle: By driving the second torque motor 26 to rotate the transmission wheel 27 at the output end, the frosting belt 28 will be driven to rotate under the limit of the movable limiting mechanism 31 and the adjusting wheel 37, so that one side of the frosting belt 28 can perform rust removal on the pipeline. During the operation, the hydraulic cylinder 34 can be driven to make the piston rod 35 at the output end telescopically move, causing the movable arm 36 to rotate accordingly. When the movable arm 36 drives the adjusting wheel 37 to move, due to the change in the support point position, the connecting plate 32 will move in a circular motion with the connection point of the fixed frame 29 as the axis as the movement of the adjusting wheel 37, thereby changing the rust removal angle of the frosting belt 28. When the diameter of the pipeline cannot fit the frosting belt 28, the second servo motor 21 is driven to rotate the second threaded shaft 22. The threaded cooperation between the second threaded shaft 22 and the second slider 23 converts the rotational motion of the second threaded shaft 22 into the linear motion of the second slider 23, thereby adjusting the position of the frosting belt 28.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
