Description

Movable high-pressure cleaning machine Technical Field The invention relates to the technical field of high-pressure cleaning, in particular to a movable high-pressure cleaning machine. Background The high-pressure cleaning machine is used as high-efficiency cleaning equipment widely applied to the fields of industrial equipment maintenance, vehicle cleaning, building outer wall cleaning, municipal sanitation and the like, and is characterized in that stubborn stains are quickly removed through high-pressure water flow, and in the actual use process, a high-pressure hose (or high-pressure spray pipe) connected with a spray gun is generally longer so as to meet the requirements of different working distances, however, the problems of inconvenient hose storage, complex operation, easy winding and knotting and the like commonly exist in the traditional high-pressure cleaning machine, and the working efficiency and the user experience are seriously affected. In order to solve the problem, part of equipment introduces an automatic rewinding reel driven by a spring, but most of equipment only has a basic rewinding function and lacks a reliable locking mechanism of 'pulling and stopping', and the hose is not maintained by external force after being pulled out and is often automatically contracted due to spring rebound, so that the length of a spray pipe in the cleaning process is unstable, and the operation precision and safety are affected. In addition, the existing automatic reel structure usually neglects dynamic protection and self-maintenance of a hose, sediment, greasy dirt, chemical residues and the like are easily attached to the surface of a high-pressure spray pipe after the high-pressure spray pipe is used in an outdoor or industrial environment, if the high-pressure spray pipe is not cleaned in time, long-term accumulation can accelerate ageing of the pipe wall, plug joints, even corrode lining, and the service life is shortened, while the traditional cleaning mode relies on manual wiping or flushing, so that the efficiency is low and the efficiency is difficult to be thorough, and meanwhile, if an effective drainage system is not provided, the sewage generated in the cleaning process is easy to cause environmental pollution around equipment, even infiltrate into electrical or mechanical parts, and cause faults. Accordingly, the present application provides a mobile high pressure washer to meet the needs. Disclosure of Invention The invention aims to solve the technical problems that a spray pipe is easy to retract and unstable in operation due to the fact that an automatic reel of the conventional mobile high-pressure cleaning machine lacks a reliable pull-stop locking mechanism, and meanwhile dirt on the pipe wall is difficult to clean synchronously in the retracting and releasing process. In order to solve the technical problems, the invention provides the following technical scheme: A movable high-pressure cleaning machine comprises a moving vehicle and two brackets fixedly connected to the top surface of the moving vehicle, wherein a pipeline winding assembly, a braking assembly, a guide cleaning assembly and a water supply assembly are respectively arranged above the moving vehicle, the pipeline winding assembly comprises a winding rod for winding a high-pressure spray pipe, a fixed column positioned in the winding rod, a spring fixed with the fixed column and a pipe management wheel for managing pipes, the braking assembly comprises a ratchet wheel connected with one end of the winding rod, a pawl and an electric telescopic column positioned on one side of the ratchet wheel, the guide cleaning assembly comprises an oblique spray head for cleaning the high-pressure spray pipe and a flexible scraper for scraping dirt, when a user pulls out the high-pressure spray pipe, the winding rod and the fixed column synchronously rotate to convert kinetic energy into elastic potential energy of the spring, the spring is stopped from pulling instantly, the spring is used for driving the ratchet wheel to be in a micro-motion mode, so that the pawl is meshed and locked instantly, when the pipe is wound, the electric telescopic column is accurately pulled out of the pawl, the released potential energy drives the winding rod to automatically wind the spray pipe, the pipe management wheel is ensured to be orderly arranged, and the flexible pipe is automatically cleaned with the flexible scraper and the flexible scraper is placed in a dynamic clearance between the cleaning module and the pipe wall.
