Description

Technical Field

[0001] The invention relates to railway cleaning equipment, in particular to a simple high-pressure water cleaning operation trolley for railways. Background Art

[0002] At present, my country's railway cleaning equipment is mainly divided into two categories: railway vehicle cleaning equipment and railway line cleaning equipment. Railway vehicle cleaning equipment is mainly used to clean dirt, oil and other dirt on the surfaces of railway vehicles, while railway line cleaning equipment is mainly used to clean dirt on the surfaces of railway ballasts, tunnels, bridges and signboards. Due to the characteristics of long operating mileage, wide distribution range and short window period of my country's railways, and the lack of special equipment for cleaning large railway lines, except for urban rail transit (subway) lines, most of the remaining railway lines hardly carry out any cleaning operations, and only important lines that pose a serious threat to vehicle operation safety and personnel health are cleaned. The cleaning methods are mainly manual cleaning and large-scale mechanical equipment cleaning. Manual cleaning has technical defects such as low operating efficiency, poor effect and high labor intensity. Although large-scale mechanical equipment cleaning has high operating efficiency and good effect, it has technical defects such as complex structure, high manufacturing and operation and maintenance costs, and is only suitable for long-distance and large-scale operations, and poor operational flexibility.

[0003] The Chinese utility model patent with patent number ZL201420865410.8 discloses a railway tunnel cleaning vehicle, which includes: a first cleaning device, a second cleaning device, a first cleaning device control system and a second cleaning device control system; the first cleaning device and the second cleaning device are symmetrically installed at both ends of the frame of the railway tunnel cleaning vehicle; the first cleaning device control system is electrically connected to the first cleaning device for controlling the first cleaning device, and the second cleaning device control system is electrically connected to the second cleaning device for controlling the second cleaning device. In this utility model, the first cleaning device and the second cleaning device are symmetrically installed at both ends of the frame, which is convenient for the staff to flexibly adjust the running direction and cleaning position of the cleaning vehicle according to specific needs, and complete the cleaning work flexibly and conveniently. However, this utility model belongs to large-scale railway line cleaning equipment, which is only suitable for the cleaning of urban rail transit (subway) tunnels. It still has technical defects such as complex structure, high manufacturing and operation and maintenance costs, only suitable for long-distance and large-scale operations, and poor operation flexibility. Therefore, it still needs to be improved.

[0004] The Chinese utility model patent with patent number ZL201821124378.2 discloses an automatic cleaning and dust removal rail vehicle, which is based on a flatbed car, with an operating room in front of the front flatbed car, and a generator compartment and a front car water tank are arranged in sequence behind the operating room, wherein a front side wall upper wall nozzle is arranged in front of the front car water tank, and a rear side wall upper wall nozzle, a sewage recovery and cleaning device, a low-pressure water pump group and a high-pressure water pump group are arranged in sequence behind the front car water tank; a front spray gun is arranged in front of the operating room, and a high-pressure water spray group and a low-pressure water spray group are arranged in the middle position below the front flatbed car; the rear flatbed car is connected to the front flatbed car, and a rear car water tank is arranged on the rear flatbed car. Compared with the current manual cleaning, this utility model is safe, efficient and highly automated; it is suitable for the cleaning operations of all 1435mm gauge rail transit facilities and is environmentally friendly, with a wastewater recovery device and no emissions. However, this utility model belongs to large-scale railway line cleaning equipment, which is only applicable to cleaning and dust removal operations in the construction and operation of urban rail transit (subway), and still has technical defects such as complex structure, high manufacturing and operation and maintenance costs, only applicable to long-distance and large-scale operations, and poor operational flexibility.

When the operation trolley is working, the water pump motor is started through the electrical control box 5, and the pressure at the outlet of the high-pressure water pump 2 is adjusted by the pressure regulating overflow valve. The water with appropriate pressure and flow after pressure regulation flows through the first rubber hose and the second rubber hose respectively and is transported to the spray gun 45 or the cleaning nozzle 33, and then the spray gun 45 or the cleaning nozzle 33 is controlled to be turned on and off by manually operating the valve. At the same time, the operation trolley is manually pushed forward to achieve the cleaning operation of the railway line within a certain range.

[0040] The present invention has a simple and reliable structure, convenient operation, and strong flexibility. Compared with the existing manual cleaning operation method, it not only has higher cleaning efficiency and better cleaning effect, but also can save labor and significantly reduce the labor intensity of operators. It is particularly suitable for narrow areas such as tunnels, bridges and culverts where large-scale railway line cleaning equipment cannot be used to carry out operations. Compared with the existing large-scale mechanical equipment cleaning operation method, the present invention has the advantages of strong flexibility, low manufacturing and operation and maintenance costs, and simple operation.
