Assembled large concrete pipeline crawling operation device

Abstract

The invention discloses an assembly type large concrete pipeline crawling operation device. An upper supporting plate, a left supporting plate and a right supporting plate are connected with two upper wheel set supports, two left wheel set supports and two right wheel set supports correspondingly through rotating couplers fixed symmetrically. The two sides of each upper wheel set support, the two sides of each left wheel set support and the two sides of each right wheel set support are fixedly provided with left driving motors and right driving motors. Left driving wheels and right driving wheels are fixed to motor shafts of the left driving motors and the right driving motors. Six pairs of electric push-pull rods separately fixed to the two ends of each of adjustable assembling supporting arms are connected with the upper supporting plate, the left supporting plate and the right supporting plate through connecting rod brackets so as to form a equilateral triangle. A device control unit with a cable is fixed to one adjustable assembling supporting arm. The device is widely used for the field of large hydroelectric power plants and other related fields.

Description

Technical field: [0001] The invention relates to a device for crawling on the inner surface of a large concrete pipeline. Background technique: [0002] With the large increase in the number of large hydropower stations, there are more and more large concrete water supply pipelines that provide the working water of the turbines. For those with a diameter of more than five meters, a height difference of about 70 to 80 meters, an inclination angle of about 60°, and a length of one The inspection and maintenance of concrete water supply pipelines of more than 200 meters or even longer are imminent, but at present, manual scaffolding is still used to inspect and maintain such large concrete pipelines. When the method is in the horizontal state, the single arm will be deformed and the whole device will slide down, which will bring huge hidden dangers to the life and property of the operator. Therefore, there is an urgent need in this field for a safe, reliable and mobile crawler ...

[0002] With the large increase in the number of large hydropower stations, there are more and more large concrete water supply pipelines that provide the working water of the turbines. For those with a diameter of more than five meters, a height difference of about 70 to 80 meters, an inclination angle of about 60°, and a length of one The inspection and maintenance of concrete water supply pipelines of more than 200 meters or even longer are imminent, but at present, manual scaffolding is still used to inspect and maintain such large concrete pipelines. When the method is in the horizontal state, the single arm will be deformed and the whole device will slide down, which will bring huge hidden dangers to the life and property of the operator. Therefore, there is an urgent need in this field for a safe, reliable and mobile crawler that can crawl in large concrete pipelines. installation
