Combined motor vehicle for highway and bridge marked line clearing

Abstract

The invention provides a combined motor vehicle for highway and bridge marked line clearing. The combined motor vehicle comprises a flat plate transportation vehicle and a driving type water clearingvehicle positioned at the front side of the flat plate transportation vehicle, wherein a clean water box, a hydraulic system, a first engine, a diesel tank, a power generator, a storage battery, a water feeding pump, a high-pressure water pump and a vacuum pump are arranged on the flat plate transportation vehicle; a water inlet of the high-pressure water pump is connected with the bottom of the clean water box through a high-pressure water inlet pipe; an air extraction opening of the vacuum pump is connected with a water outlet of the high-pressure water pump connected with the upper part ofthe front side of a slag and water collecting and discharging device through a vacuum pumping pipe and is connected with a water inlet of a high-pressure water clearing disc assembly through a high-pressure water outlet pipe; a slag and water inlet of the slag and water collecting and discharging device is connected with a slag suction water opening of the high-pressure water clearing disc assembly through a fixed slag suction pipe. The combined motor vehicle has the advantages that the clearing effect is very good; waste water and residue slag can be recovered; the construction effect and theconstruction effect can be effectively improved. The high-pressure water clearing automation degree is improved; the work intensity of workers is reduced, so that the popularization and the application of the high-pressure water in aspects of automation and industrialization can be promoted.

Description

technical field [0001] The invention belongs to the technical field of clearing road markings, in particular to a combined motor vehicle for clearing road and bridge markings. 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 Water Removal Vehicle". This equipment has high removal efficiency and reliable sealing. It over...

[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 Water Removal Vehicle". This equipment has high removal efficiency and reliable sealing. It overflows to the ground, and the waste water and residue after clearing the marking line will splash on the ground and stay on the falling surface, polluting the environment and affecting the cleanliness of the road. Therefore, it is an urgent need to recycle the waste water and residue after clearing the marking line Problems to be solved; 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 flow normally Spraying 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

In addition, the cleaning vehicle relies on manual propulsion for operation, which is labor-intensive. The cleaning range of the equipment is limited and cannot be adjusted according to the marking situation. For example, when the marking line to be cleared is wide, the equipment cannot To clear the marking line, it needs to be cleared twice or even multiple times
