Description
Technical Field
The invention relates to pipeline processing, in particular to a pipeline detection device.
Background
A pipeline is a device for transporting a gas, liquid or fluid with solid particles, connected by pipes, pipe couplings, valves, etc. Generally, a fluid is pressurized by a blower, a compressor, a pump, a boiler, etc., and then flows from a high pressure portion to a low pressure portion of a pipe, or is transported by the pressure or gravity of the fluid itself. The use of pipelines is very widespread, mainly in water supply, drainage, heating, gas supply, long-distance oil and gas delivery, agricultural irrigation, hydraulic engineering and various industrial installations. Because the pipeline is longer, the roundness detection workload of the pipeline is large, and the efficiency is low.

Aiming at the problems, the invention provides the pipeline detection device which is simple in structure, convenient to detect and capable of improving the working efficiency.
The technical scheme of the invention is as follows: the pipeline is arranged on the support; the detection device comprises a motor and a gear transmission mechanism, wherein the motor is arranged on the pipeline and drives the gear transmission mechanism;
the gear transmission mechanism comprises an outer gear, an inner gear and a telescopic rod, the outer gear is arranged on an output shaft of the motor, the inner gear is meshed with the outer gear, a plurality of rolling mechanisms are arranged on the annular surface of one side of the inner gear, so that rollers of the inner gear are connected to the first pipeline, the telescopic rod is arranged on one side of the inner gear, the telescopic rod and the rolling mechanisms are located on the same side of the inner gear, and a contact head is arranged on the telescopic rod.
The rolling mechanism comprises a connecting rod, a second roller and a pair of baffles, the pair of baffles are arranged in parallel, a rotating shaft is arranged between the pair of baffles, the second roller is arranged on the rotating shaft, and the connecting rod is connected with the baffles and the internal gear.
The contact head is connected with an alarm.
In the working process, the motor drives the external gear, the external gear drives the internal gear to rotate, and the internal gear is arranged on the pipeline through the rolling mechanism, so that the internal gear can reliably rotate; when the inner gear moves, the telescopic rod drives the contact head to rotate, and when the contact head contacts with a local pipeline, an alarm is given; the telescopic link flexible action can contact different positions of pipeline, convenient detection. The invention is convenient to operate and saves the working time.
