Problems solved by technology

[0002] After the oil and gas transmission pipeline is laid and used for a period of time, it needs to be cleaned and tested regularly due to the influence of wax deposition, sand deposition or external factors. There are various types of cleaning devices: leather bowl type, leather bowl straight plate combination type, straight plate type , leather bowl and steel brush combination, straight steel brush combination, and straight aluminum plate combination. The specific facilities need to be carried out in sequence according to the specific conditions of the pipeline. Usually, each pipeline needs to be cleaned in multiple combinations and in multiple batches. The skeleton of the pigging device currently in use is a fixed steel structure, sometimes it is difficult to replace the combination on site, and the scale cannot be adjusted

Embodiment Construction

[0016] Now combined with the manual figure 1 , attached figure 2 The present invention is further described:

[0017] A combined cleaning and measuring device in a pipeline mainly consists of an anti-collision head 1, a front guide plate 2, a thin backing plate 3, a front sealing piece 4, a thick backing plate 5, bolts 6, a rear sealing piece 7, a rear guide plate 8, and a pressure plate 9 composition.

[0018] Anti-collision head 1, front guide plate 2, thin backing plate 3, front sealing plate 4, thick backing plate 5, rear sealing plate 7, rear guide plate 8, pressure plate 9 are fixed together by bolts 6 uniformly distributed along the circumferential direction, and the front guide plate 2. The outer periphery of the front sealing sheet 4, the rear sealing sheet 7, and the rear guide plate 8 can be in the shape of a bowl or a flat plate of rubber material, and the quantity is not limited.

[0019] When pipe diameter measurement is required, a mechanical telescopic gaug...

Abstract

The invention relates to a pipeline internal combined type cleaning and diameter measuring device and method. The pipeline internal combined type cleaning and diameter measuring device and method are applied to pipeline internal cleaning and mechanical diameter measuring. An anti-collision head, a front guide plate, base plates, a front sealing piece, thick base plates, a back sealing piece, a back guide plate and a pressing plate are fixed together through bolts uniformly distributed in the circumferential direction to form the pipeline cleaning device. A framework structure of the device is formed through the anti-collision head, the base plate, the thick base plate and the bolts, and the size, the shape and the function of the device can be adjusted very conveniently according to the specific pipeline condition; therefore, the pipeline internal combined type cleaning and diameter measuring device has the characteristics of being high in adaptability, easy and convenient to operate, light in weight and good in economy.

Description

technical field [0001] The invention relates to a combined cleaning and measuring device in a pipeline in the field of pipeline cleaning devices, which is applied to cleaning and measuring the inside of a pipeline. Background technique [0002] After the oil and gas transmission pipeline is laid and used for a period of time, it needs to be cleaned and tested regularly due to the influence of wax deposition, sand deposition or external factors. There are various types of cleaning devices: leather bowl type, leather bowl straight plate combination type, straight plate type , leather cup steel brush combination, straight steel brush combination, straight aluminum plate combination, the specific facilities need to be carried out in sequence according to the specific conditions of the pipeline, usually each pipeline needs to be cleaned in multiple combinations and in multiple batches The skeleton of the pigging device currently in use is a fixed steel structure, and sometimes it...
