A kind of pneumatic centrifugal spray construction inspection well repair equipment, engineering vehicle and repair method

Abstract

The invention relates to a kind of pneumatic centrifugal jetting inspection well repair equipment, which comprises a supporting device, a pulping device, a pumping device, a lifting device and a pneumatic rotary jetting device, and the pneumatic rotary jetting device is provided with a locking device for the pneumatic rotary jetting. The locking structure of the pneumatic rotor of the device; the lifting device includes a boom, a lifting rod, a lifting pump, a rotary table and a rotating motor, one end of the boom is installed on the support device, and the other end of the boom rotates The rotary table is connected to the rotary table, and the rotary motor is connected to the rotary table and drives the rotary table to rotate. The rotary motor is installed on the suspension arm, and the upper end of the lifting rod is fixed on the rotary table. The lift rod is connected to the lift pump, the lift pump is installed on the rotary table, and the lower end of the lift rod is fixedly connected to the pneumatic rotary spray device. The present application has the effect of improving the defect that the pneumatic rotary spray device is easy to swing.

Description

technical field [0001] The invention relates to the field of inspection well repair, in particular to a pneumatic centrifugal jetting inspection well repair equipment, an engineering vehicle and a repair method. Background technique [0002] The urban underground pipeline network is an important infrastructure construction of the city, and it is the "underground lifeline" to ensure the normal operation of the urban functions as a whole. With the continuous acceleration of urbanization in my country, the amount of urban underground pipeline expansion and renovation projects continues to increase. As an important part of the drainage system, inspection wells are known as the "windows" of drainage pipelines. An inspection well is set every 40m of drainage pipelines on average. According to rough statistics, there are currently only 15.75 million drainage inspection wells in cities across the country, which need to be repaired urgently. [0003] The related art discloses a pneu...

Problems solved by technology

However, when the repair equipment is in use, when the gas enters and exits the pneumatic swirl spray device, it will generate a driving force on the pneumatic swirl spray device, causing the pneumatic swirl spray device to swing, which will affect the quality of spraying. At the same time, the swing of the pneumatic swirl spray device is easy Colliding with the side wall of the inspection well, destroying the sprayed lining slurry layer

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the pneumatic swirl spray device of the repair equipment in the related technology is easy to swing
