Abstract

The invention relates to a pipeline detector dragging device. The pipeline detector dragging device is mainly composed of a rack, a controller, a magnetic exchange valve, a cardan joint, a battery, a motor, a hydraulic pump, an oil tank, position sensors, a signal generator, a large hydraulic cylinder, a large piston, a large piston rod, a small hydraulic cylinder, a small piston rod, an elastic friction block, a check valve, a small piston, a rear support rod, a rear sleeve, a friction plate, a sealing element, front sleeves, front support rods, a connector and the like. The rack is connected with the large piston rod through the cardan joint, the position sensors are installed on the large piston rod, the signal generator is installed on the sealing element, the check valve is installed on the small piston, the elastic friction block is installed on the small piston, the friction plate is installed on the rear sleeve, and the small hydraulic cylinder is installed on the large hydraulic cylinder. The pipeline detector dragging device has the advantages of being compact in structure, high in traction force and variable in diameter, the detector can be dragged to conduct internal inspection on a petroleum and natural gas pipeline with different sizes.

Description

technical field [0001] The invention relates to a dragging device for a pipeline detector, which belongs to the dragging device for pipeline detectors in petroleum, natural gas, gas, chemical industry and the like. Background technique [0002] With the continuous development of oil and gas surface projects at home and abroad, pipelines have become the main means of oil and gas transportation. Not only that, a large number of pipelines are also used in the construction of chemical and urban gas projects. Due to the action of corrosive media and external forces, the oil and gas pipeline network has caused inevitable accident risks. In order to prevent accidents, it is necessary to regularly check the performance of the pipeline. At present, the commonly used detector driving methods at home and abroad are divided into two types: passive and active. Among them, the passive driving method is driven by the pressure in the pipeline. This method is mainly used in large-diameter...
