Combined type marking removal engineering vehicle for road construction

Abstract

A combined type marking removal engineering vehicle for road construction comprises a flatbed transporter and a hand-push high-pressure water removal vehicle located on the front side of the flatbed transporter. The flatbed transporter is provided with a slag and water collection and drainage device, a clean water tank, a hydraulic system, an engine, a diesel tank, a generator, a storage battery,a charging pump, a high-pressure water pump, a vacuum pump, a primary filtration system and a secondary filtration system. The water outlet of the high-pressure water pump is connected to the water inlet of the hand-push high-pressure water removal vehicle through a high-pressure water outlet pipe. The suction port of the vacuum pump is connected to the upper portion of the front side of the slagand water collection and drainage device through a vacuumization pipe. The slag and water inlet of the slag and water collection and drainage device is connected to the slag and water suction port ofthe hand-push high-pressure water removal vehicle through a fixable connection type slag suction pipe assembly. The combined type marking removal engineering vehicle for road construction has a good removal effect, the waste water and the slag can be recovered, the construction efficiency and the construction effect are effectively improved, the degree of automation of high-pressure water removalis also improved, the labor intensity of the workers is reduced, and the popularization and application of high-pressure water to the fields of automation and industrialization are promoted.

Description

technical field [0001] The invention belongs to the technical field of road marking removal, and in particular relates to a combined road marking removal engineering vehicle. Background technique [0002] High-pressure water cleaning technology is used in many places in China, such as ports, docks, railways and industries for rust removal, etc. When traditional high-pressure water jet cleaning machines remove markings on the road, they mainly use hand-held spray guns or hand push The type trolley removes the marking line. This cleaning method is not only labor-intensive, but also has low cleaning efficiency, low degree of automation, and poor effect of clearing the marking line. Therefore, the further promotion and application of the high-pressure water cleaning machine is limited. [0003] The patent document with the application number 201610302969.3 discloses a "road marking hand-push high-pressure water removal vehicle". This equipment has high removal efficiency and rel...

Problems solved by technology

[0002] High-pressure water cleaning technology is used in many places in China, such as ports, docks, railways and industries for rust removal, etc. When traditional high-pressure water jet cleaning machines remove markings on the road, they mainly use hand-held spray guns or hand push The type trolley removes the marking line. This cleaning method is not only labor-intensive, but also has low cleaning efficiency, low degree of automation, and poor effect of clearing the marking line. Therefore, the further promotion and application of high-pressure water cleaning machines are limited.

[0003] The patent document with the application number 201610302969.3 discloses a "road marking hand-push high-pressure water removal vehicle". This equipment has high removal efficiency and reliable sealing. It will overflow to the ground, and the waste water and residue after clearing the markings will splash on the ground and stay on the falling surface, polluting the environment and affecting the cleanliness of the road. Therefore, it is necessary to recycle the waste water and residues after clearing the markings Problems that need to be solved urgently; secondly, the nozzle seat of the equipment has a cavity structure, and a high-pressure nozzle connected to the cavity structure is installed on the lower surface of the nozzle seat, but sometimes there will be blockage in the nozzle seat, and the high-pressure water cannot normally flow The nozzle sprays to the ground. In this case, the nozzle seat cannot be repaired to clear its cavity, and the nozzle seat can only be replaced, which will undoubtedly increase the construction cost of road marking cleaning.
