Embodiment Construction

[0023] The present invention is not limited by the following implementation examples, and specific implementation manners can be determined according to the technical solutions of the present invention and actual conditions. Combine below figure 1 , figure 2 , image 3 The present invention is described below. The positional relationship of up, down, left, right, etc. is based on the attached figure 1 determined by the layout direction.

[0024] Such as figure 1 As shown, the base 17 is in the shape of a truncated cone as a whole, and the outer end surface of the base 17 is provided with a connecting ring 24 and connected with bolts. The connecting ring 24 is used to connect other pigs or pipeline testing equipment. The base 17 is radially provided with a slot with a rectangular cross section, and the bracket 20 is installed in the slot in the middle of the base 17 , and the bracket 20 can slide in the slot in the middle of the base 17 along the radial direction of the b...

Abstract

The invention relates to a brake device of a pipe cleaner, which can reduce the running speed of the pipe cleaner and prevent the pipe cleaner from causing an impact. The brake device adopts the technical scheme as follows: a speed acquisition wheel presses against the inner wall of a pipeline by virtue of a hydraulic pressure and drives a hydraulic pump to work, the hydraulic pump drives a central mass block to rotate, a centrifugal force of the mass block is transmitted to a brake block through a link mechanism to generate a pressing force, and the pressing force is directly proportional to the running speed of the pipe cleaner. The brake device of the pipe cleaner is only needed to be arranged on the rear side of the pipe cleaner, can carry detection equipment and is suitable for various pipe cleaning operations.

Description

technical field [0001] The invention relates to a pipe pig brake device. Background technique [0002] In the process of pigging and testing oil and gas pipelines, general regulations require that the running speed of the pigging equipment is 3.5-5m / s; in order to obtain better quality of testing data, the running speed of the testing equipment in the pipeline is required to be lower than 5m / s ; Electromagnetic testing, ultrasonic testing and other equipment require their operating speed to be lower than 2m / s. The speed of the pigs changes greatly when passing through the uphill and downhill sections, curved sections, liquid accumulation, sand accumulation and fouling sections of the pipeline, and the direct use of conventional pigs cannot meet the speed control requirements. [0003] The speed control modes of existing oil and gas pipeline pigs are active control mode and passive control mode. [0004] The active control adopts the bypass valve control method, and its tec...
