Description

A kind of tunnel cleaning systems based on piston effect

Technical field

It the utility model is related to tunnel cleaning technology field, especially a kind of tunnel cleaning systems based on piston effect.

Background technology

As China's economic is fast-developing, urbanization process is progressively accelerated, city size constantly expands, and urban transportation is more next More crowded, to alleviate traffic pressure, subway is greatly developed in many cities.As subway mileage increases sharply, in subway tunnel Cleaning is increasingly heavy.The operating environment of subway tunnel not only influences environmental beauty in subway tunnel, also to railcar row Car constitutes a threat to safely.Therefore, it is to ensure the important component of metro safety operation to keep subway tunnel cleaning.

Issued according to China's report hall《2014-2018 Chinese city track traffic market depth analysis reports》Can Know, by the end of 2015,38, China city possessed 158 circuits, and operation mileage amounts to 4190 kilometers；" 13 " period, China will enter the Construction of Urban Rail Traffic great development stage, and the year two thousand twenty planning circuit mileage will be more than 10000 kilometers.Thus may be used Know, traditional artificial clean method cannot meet the needs of present Development of underground railway, it is therefore desirable to develop novel device with full Sufficient Development of underground railway demand.

Subway tunnel major pollutants have：The large volume pollutant such as peel and paper, beverage bottle, polybag；Be attached to wall, Dust on cable；The pellets such as PM2.5, PM10 and in train travelling process because mechanical wear produce metal Fines.

As subway tunnel pollution administering method, it is known that have：Dust suction is combined method, dust suction with purging and spilling with purging Water rinses and is combined method, vacuum cleaning is combined method etc. with round brush rolling and brushing and high pressure water cleaning.

Method is combined with purging for dust suction, just like patent document " a kind of railway tunnel sweeper ", CN201598592U, The applying date is 2010.10.06, by will be connected loaded on vacuum railway carriage or compartment one end on railway platform truck with the air entry inhaled, blowing pumps Logical, the round tube hole on the end plate top of the other end is externally provided with tens of air intake ducts and drags on road surface, and in vacuum railway carriage or compartment left end upper plate and Equipped with the densely covered besom that can be established and put upside down on right plate, make the flat car in the process of moving, can be to subway tunnel at the same time Carry out floor suction and inner wall cleans, have the advantages that compact-sized, cleaning speed is fast, efficient.But this method was cleaning The phenomenon that flying dust rises from all around is not only resulted in journey, and needs to consume a large amount of electric energy in operation；In addition, the operation of the car Speed need to be in lower-speed state, so that cleaning efficiency is relatively low.

Method is combined with the flushing that purges and sprinkle water for dust suction, just like patent document " railway tunnel cleaning car " CN101967809A, applying date 2011.02.09, by by control section, vacuum part, purging part and water flushing section It is sequentially arranged on flat car, in flat car operational process, vacuum part, purging part and water flushing section work at the same time, and pacify Dust stratification on facility in tunnel wall and its tunnel is peeled off and recycled by the vacuum part loaded on middle front part on flat car, is installed on flat The purging part of middle and back blows ground refuse, debris, dust and metal fines progress dust suction purging with manual dust suction on wooden handcart Processing is swept, the water flushing section below flat car is installed on and removing is rinsed to subway tunnel part stain.The practicality It is new to have the characteristics that compact-sized, full-featured, effect is good.But the implementation of this method not only needs substantial amounts of water resource and electricity The power energy, and a large amount of spray water can cause moisture in subway tunnel to diffuse, or even can freeze in the winter time, to train operation and The safety belt of passenger comes very big unfavorable.In addition, within the speed of service of the car is when 5km/ is small, cleaning is greatly reduced Efficiency.

Method is combined with round brush rolling and brushing and high pressure water cleaning for vacuum cleaning, " subway tunnel is clear just like non-patent literature Clean car technological development and research " (Duan Xiao, Shandong University's master thesis, 2011.11.30), by the way that vacuum system is drawn System, round brush rolling and brushing system and high pressure water washing system are sequentially arranged on flat car, in flat car operational process, vacuum system System extraction system, round brush rolling and brushing system and high pressure water washing system work at the same time, respectively to subway tunnel inner wall, ground and part Stain is cleaned, full-featured.But the problems of implementation of this method is equally great lot of water resources and electric power It is unfavorable that the consumption of the energy and a large amount of spray waters are come to the operation of train and the safety belt of passenger.In addition, the operation of the car Within speed is when 5km/ is small, cleaning efficiency is greatly reduced.

In conclusion although the starting point of the above method is all effective cleaning subway tunnel, but the implementation of every kind of method is equal There are a critical defect, i.e., need to consume a large amount of electric energy and low speed operation can be only achieved Expected Results, so that cleaning efficiency is too low. In addition, the water flushing section involved in latter two method can not only consume great lot of water resources, but also a large amount of spray waters can be made Moisture diffuses into subway tunnel, or even can freeze in the winter time, and it is very big unfavorable to come to the operation of train and the safety belt of passenger.
