Abstract

The invention belongs to the technical field of spraying devices, in particular to a spraying device for pipeline repair and its use method, including spraying equipment; the end of the spraying equipment is equipped with a spray head; mouth; the end of the nozzle is provided with an arc-shaped notch; the side wall of the arc-shaped notch is fixed with a soft seal; the side wall of the soft seal is fixed with a rubber belt; the end of the nozzle An elastic support rod is fixedly connected; the end of the elastic support rod is rotatably connected with a protective soft wheel; the middle part of the protective soft wheel is rotatably connected with a strut; the other end of the strut is hinged on the side wall of the spray head; There is an arc-shaped notch at the nozzle of the pipe, which can be attached to the pipe wall, and then sprayed on it, so that the spray liquid can be evenly sprayed on the pipe wall, reducing the waste of spray liquid.

Description

technical field [0001] The invention belongs to the technical field of spraying devices, in particular to a spraying device for pipeline repair and its application method. Background technique [0002] Spraying equipment is a product of the environment where automation is becoming more and more common with the development of industrial technology after the reform and opening up. With the increasing degree of automation, the application of spraying production lines is becoming more and more extensive, and penetrates into many fields of the national economy. The spraying equipment currently on the market can be divided into three types according to the degree of automation: manual spraying equipment, semi-automatic spraying equipment and fully automatic spraying equipment. [0003] There are also some technical solutions about construction spraying devices in the prior art. For example, a Chinese patent with application number 2019112976277 discloses a spraying device for pip...
