Abstract

The invention relates to a pipe cleaning device with an automatic brake device. The pipe cleaning device is used for pipe cleaning work. The defect that an existing speed adjusting pipe cleaning device is poor in generality in a pipe is overcome. According to the technical scheme, leather bowls are arranged at the two ends of a cylinder, one end of a connecting rod B is hinged to a brake piece, the other end of the connecting rod B is hinged to the cylinder, one end of a connecting rod C is hinged to the brake piece, the other end of the connecting rod C penetrates a groove hole of the cylinder and is hinged to a mandrel, a brake oil cylinder is arranged in the cylinder, a piston rod of the brake oil cylinder is connected with the mandrel, rollers are mounted on input shafts of hydraulic pumps, a supporting spring is arranged between the two hydraulic pumps which are arranged at the rear end of the cylinder, an oil tank is arranged in the cylinder, oil suction openings of the hydraulic pumps are connected to the oil tank, oil outlets of the hydraulic pumps are connected to a throttling valve, an oil returning opening of the throttling valve is connected to the oil tank, and the front end of the throttling valve is connected with the brake oil cylinder. A pipe cleaning device speed controller is free of an electric appliance element, safety and reliability are achieved, and the device has the high generality in the pipe.

Description

technical field [0001] The invention relates to a pipe pig with an automatic braking device, which is used for pipe pigging operations. 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 equipment in the pipeline is required to be lower than 5 m / s. s; electromagnetic ultrasonic testing equipment requires its operating speed to be lower than 2 m / 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 b...
