Railway tunnel cleaning trolley

Abstract

The invention relates to the technical field of railway tunnel environmental protection, in particular to an urban subway tunnel cleaning trolley, which mainly comprises a flat trolley, a control part, a dust absorption part, a sweeping part and a water flushing part, wherein the control part, the dust absorption part, the sweeping part and the water flushing part are orderly arranged on the flat trolley; one end of a filter-bag dust remover installed at the middle front part of the flat trolley is communicated with the air inlet of a centrifugal fan through a metal pipeline and an autothrottle; the other end of the filter-bag dust remover is communicated with a draught distributing box, which is provided with regular through holes, connected with a control air valve and provided with dust absorption ports on the periphery of the cross section; a dust deposit bucket on the lower part of the filter-bag dust remover is provided with a plurality of spiral conveyers longitudinally; the conveyers are connected with a motor reducing gear through chains and chain wheels to form the dust absorption part; the air inlet end of an air storage tank installed at the middle rear part of the flat trolley is communicated with a high-efficiency screw type air compressor, and the air outlet at the other end is communicated with a high pressure seamless pipe, which is connected with an angle-adjustable TB slot type structure air injection nozzle, an electromagnetic regulating valve and a manual pressure relief valve to form a sweeping part; and the water inlet end of a plunger type high-pressure water pump installed at the middle rear part of the flat trolley is communicated with three water tanks installed on the upper part of the flat trolley, and the other end is communicated with two high-pressure water jets arranged at the rear end part of the flat trolley to form the water flushing part. The invention has various advantages is suitable for various railway tunnels.

Description

Technical field: [0001] The invention relates to the technical field of railway tunnel environmental protection, in particular to an urban subway tunnel cleaning vehicle. Background technique: [0002] With the acceleration of urbanization in the mainland of my country and the rapid development of the railway industry, urban rail transit is gradually entering a stage of steady, orderly and rapid development. In the next 10 years, more than 60 new urban rail transit lines will be built in mainland my country, with a mileage of nearly 1700km. Beijing, Shanghai, and Guangzhou are developing at an annual rate of 30-50 km. Due to high-density operation, short intervals between trains, high speeds, and a large number of trains, urban rail transit has a large transportation capacity. Over the years, subway trains have shuttled continuously, causing serious pollution to urban tunnels, and with the accumulation of operation time, tunnel pollution will become more and more serious, ...

Problems solved by technology

However, due to the complexity of the track bed in urban tunnels, the functions of sweeping and vacuuming are greatly limited
