Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for pigging operation, and particularly relates to a device for grasping a pigging ball. Background Art

[0002] In the process of oil and gas field production, a pigging ball is often used to clean a pipeline. When in use, the pigging ball is moved inside the pipeline to remove impurities and sewage on the inner wall of the pipeline.

[0003] In the prior art, a switch is generally arranged on a holding seat, and the grasping mechanism is controlled by operating the switch, so as to realize the grasping action of the pigging ball. However, due to the influence of impurities or sewage in the pipeline, it is difficult to clearly see the position of the pigging ball when grasping the pigging ball, and the pipeline is narrow and dark, which increases the difficulty of grasping the pigging ball. At the same time, due to the different lengths of the pipelines where the pigging balls are located, the lengths of the existing devices are often difficult to adjust. When the pigging ball is near the pipeline opening, when the device with too long length grasps the pigging ball, the force arm of the end near the pigging ball is often longer, and the force arm of the end operating the device is often shorter. Due to the lever principle, it is laborious to take out the pigging ball. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defect that in the prior art, due to the influence of impurities or sewage in the pipeline, it is difficult to clearly see the position of the pigging ball when grasping the pigging ball, and the pipeline is narrow and dark, which increases the difficulty of grasping the pigging ball, and to provide a device for grasping a pigging ball.

[0005] The utility model provides a device for grasping a pigging ball, which comprises a cylinder body. One end of the cylinder body is provided with an operation part, and the other end is provided with a grasping part. The operation part is slidably connected to the cylinder body. The operation part is connected to the grasping part through a transmission mechanism. The grasping part comprises a plurality of grasping units. Moving the operation part can open or close the grasping part. The cylinder body is also provided with a lighting device.

[0006] An operating part is provided at one end of the cylinder, and a grabbing part is provided at the other end. When in use, the end provided with the grabbing part is extended into the pipeline, and the grabbing part is driven to move axially inside the pipeline by the axial movement of the cylinder along the pipeline. The length provided by the cylinder enables the grabbing part to move a longer distance in the pipeline, thereby improving the ability of the device for grabbing the pipe cleaning ball to grab the pipe cleaning ball; the operating part is slidably connected to the cylinder so that the operating part can slide relative to the cylinder, and the operating part is connected to the grabbing part via a transmission mechanism. By making the operating part slide relative to the cylinder, the force generated by the movement of the operating part is transmitted through the transmission mechanism To the grabbing part, thereby driving the grabbing part to open or close. The opening of the grabbing part means that the ends of the grabbing units in contact with the cleaning ball are away from each other, and the closing of the grabbing part means that the ends of the grabbing units in contact with the cleaning ball are close to each other. Through this arrangement, the opening or closing of the grabbing part can be achieved by moving the operating part, thereby achieving the grabbing of the cleaning ball, thereby improving the convenience of using the device; by arranging lighting equipment, when there are more impurities or sewage in the pipeline, the lighting equipment can illuminate the environment in the pipeline, making it easier to find the position of the cleaning ball, thereby reducing the difficulty of the device to grab the cleaning ball and improving the convenience of using the device.

[0014] The cylinder is telescopic and comprises a plurality of cylinder units, the plurality of cylinder units are slidably connected to each other, and the cylinder is provided with a locking member, which is used to fix the positions of two adjacent cylinder units.

[0015] By setting the cylinder body to be telescopic and the cylinder body units to be slidably connected, the cylinder body units can be slid according to actual usage requirements, changing the relative positions between several cylinder body units, and thus changing the length of the cylinder body, improving the adaptability of the device; when the relative positions between the cylinder body units are adjusted, by operating the locking member, the positions of several cylinder body units are relatively fixed, thus facilitating the use of the device.

[0023] Furthermore, the elastic component can be set as a spring or an elastic diaphragm, etc.

[0024] The transmission mechanism includes a traction component and a pulley, and the pulley is respectively connected to the operation part and the grasping part through the traction component.

[0025] By using the traction component and the pulley to connect the operation part and the grasping part, that is, the transmission mechanism is a pulley transmission system. Through this setting, the pulling force exerted by the operation part on the grasping part can be amplified, enabling the operator to open or close the grasping part with a smaller force.
