Description

Technical Field

[0001] The utility model belongs to the field of oil pipe cleaning equipment, in particular to an oil pipe inner wall cleaning device. Background Art

[0002] The crude oil extraction equipment in the prior art needs to be connected to various oil production pipelines. The oil production pipeline is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after drilling is completed. It is used to withstand the pressure generated during the extraction process. During the oil extraction process, due to the viscosity of crude oil and the presence of impurities such as mud and sand in crude oil, a large amount of dirt will be attached to the inner wall of the oil production pipeline, affecting the quality of the oil. Since the oil pipeline is long, most of the existing ones use artificial water flushing to clean the oil pipeline, and the cleaning effect is not ideal. It is difficult to flush away the impurities adhered to the inner wall of the oil pipeline.

[0003] The Chinese patent with publication number CN216323923U discloses a cleaning device for oil pipes, including a water tank with a hollow structure inside, a rope body fixedly connected to the left side of the water tank, two rotating shafts rotatably installed on the top and bottom of the water tank, a rubber wheel fixedly sleeved on the surface of the rotating shaft, a driving motor fixedly installed on the right side of the top of the water tank, the rear end of the output shaft of the driving motor is fixedly connected to the front end of the rotating shaft located at the upper right, a support plate fixedly installed on the right side of the water tank, a first bevel gear meshing with a second bevel gear fixedly installed on the left end of the connecting shaft, and a gear fixedly installed on the right end of the connecting shaft. The utility model can effectively clean the inner wall of the oil pipe by water flushing and friction brushing, improve the cleaning effect, and automatically drive the entire device to move for brushing, which is convenient for brushing longer oil pipes.

[0004] The above cleaning devices for oil pipes can only clean the inner wall of oil pipes of fixed specifications and sizes, and are inconvenient to adjust and effectively clean the inner wall of oil pipes of different specifications and sizes.

[0005] In view of this, the present utility model is proposed. Utility Model Content

The first gear is driven to rotate by rotating the rotating shaft, so that the rack blocks on both sides move relative to each other, thereby driving the driving wheels on the lifting plates on both sides to fit with the inner walls of oil pipes of different sizes.

[0011] Optionally, two opposite sides of the rotating shaft are provided with limit grooves, one end of the rotating shaft is provided with a baffle, the baffle is slidably fitted in the fixed cylinder, one side of the fixed cylinder is provided with a latch, one side of the fixed cylinder is provided with a connecting groove, two opposite sides of the connecting groove are provided with limit blocks, the limit blocks are slidably fitted in the limit grooves, a spring is provided in the fixed cylinder, one side of the fixed cylinder is provided with an adjusting disk, the spring is sleeved on the rotating shaft, the spring is located on the side away from the adjusting disk, the baffle is located on the side close to the adjusting disk, a slot is provided on one side of the fixed frame, and the latch is plugged into the slot.

[0012] Optionally, transmission rods are provided on opposite sides of the lifting plate, driving wheels are provided at both ends of the transmission rod, a stopper is provided on one side of the rack block, a slider is provided on one side of the lifting plate, a slide groove is provided on opposite sides of the box body, the slider slides in the slide groove, a second gear is provided on the output shaft of the driving member, a third gear is provided at one end of the transmission cylinder, the third gear meshes with the second gear, a first through groove is provided in the rotating plate, a second through groove is provided in the lifting block, a sealing block is provided on one side of the lifting block, the sealing block is located in the first through groove, fixing bolts are provided on opposite sides of the rotating plate, the fixing bolts abut against one side of the lifting block, and the water outlet pipe is connected with the first through groove and the second through groove. The second gear is driven to rotate by the driving member, the third gear meshes with the second gear to drive the transmission cylinder to rotate, and the lifting blocks on both sides can be adjusted up and down in the rotating plate, so that the brush plate on the lifting block fits the inner wall of the oil pipe of different sizes, and the inner wall of the oil pipe of different sizes can be effectively cleaned by water flushing and friction brushing.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] 1. The oil pipe inner wall cleaning device drives the second gear to rotate through the driving member, and the third gear is engaged with the second gear to drive the transmission cylinder to rotate. The lifting blocks on both sides can be adjusted up and down in the rotating plate, so that the brush plates on the lifting blocks fit the inner walls of oil pipes of different sizes. Through the water flushing and friction brushing method, the inner walls of oil pipes of different sizes can be effectively cleaned to improve the cleaning effect, and the method of automatically driving the entire device to move for brushing is convenient for brushing operations on longer oil pipes.

[0015] 2. The oil pipe inner wall cleaning device drives the fixed cylinder to slide on the rotating shaft by pulling the adjusting disk, so that the pin of the fixed cylinder is disengaged from the slot, thereby releasing the limiting effect on the fixed cylinder and the rotating shaft, so that the fixed cylinder can stably slide and fit on the rotating shaft. When the adjusting disk is not operated, the spring and the baffle are in contact, and the fixed cylinder is always squeezed to make the pin located in the slot, which plays a fixed limiting role on the fixed cylinder, thereby reducing the situation in which the lifting plate moves when the box moves on the inner wall of the oil pipe, making it impossible for the driving wheel to fit the inner wall of the oil pipe.
