Sandblaster with pipe automatically wound

Abstract

The invention relates to a sand blasting tool, in particular to a sandblaster with a pipe automatically wound. The sandblaster with the pipe automatically wound is applied to pipe jacking and heating pipeline filling fixtures in heat pipelines laid based on the non-excavation technology, and is mainly composed of an air inlet pipe, a sand storage pipe and a sand outlet pipe, the air inlet pipe, the sand storage pipe and the sand outlet pipe are connected in sequence through flanges, the upper portion of the sand storage pipe is vertically and fixedly connected with a sand inlet hopper communicated with the sand storage pipe, the lower portion of the sand storage pipe is fixedly connected with supporting legs, the sand outlet pipe is connected with a sand outlet rubber pipe, and the sand outlet rubber pipe is wound on a pipe winding reel driven by a motor. Due to the fact that the sand outlet pipe is designed to be connected with the sand outlet rubber pipe, the sand outlet rubber pipe is wound on the pipe winding reel driven by the motor, the pipe winding reel is driven by the motor to automatically wind the pipe, work efficiency is improved, the speed is constant and can be regulated, and product quality is improved.

Description

technical field [0001] The invention relates to a sandblasting tool, in particular to a sandblasting device used for automatic collection of pipe jacking and thermal pipeline filling fixtures in laying heating network pipelines using trenchless technology. Background technique [0002] The heat network is composed of heat transmission trunk lines, heat distribution trunk lines, and branch lines. The heat transmission main line is drawn from the heat source, and generally does not connect to the branch line; the heat distribution main line is directly connected to the heat transmission main line or directly from the heat source, and heat is supplied to the user through the heat distribution branch line. [0003] The layout of the heating network is mainly determined according to the distribution of urban heat load, the status quo of the block, the development plan, and the geological and topographical conditions, etc., and is generally arranged in a branch shape. When heat i...

Problems solved by technology

However, this kind of equipment needs to be manually collected when the sand and rubber pipe is withdrawn while blowing the sand. Due to the manual control of the collection speed, the work efficiency is low and the product quality is poor.
