Description
Technical field
The present invention relates to high ferro train overhaul device, particularly the hot blast air-supply arrangement of railway car bottom ice-melt snow removal system.
Background technology
Winter, high ferro train was run at high speed in process in ice and snow region, can entrainment a large amount of ice and snow and be attached to car bottom, formed more closely knit ice and snow layer, and thickness is conventionally more than 8cm.4000 kilometers of the every operations of high ferro train or operation 48 hours, need to get back to Motor Car Institute and carry out an one-level maintenance, each one-level maintenance will complete in 3 and a half hours, first need to remove fast the ice and snow that car bottom adheres to, reach the ice-melt library standard that removes the snow out, must not there be residual accumulated ice and accumulated snow in the each position of train traveling portion, ensures normally carrying out of lower order upkeep operation.Therefore, on time and one-level of having guaranteed the quality maintenance be starved of quick ice-melt snow removal system be set, car bottom freezes the removal problem of ice and snow when solving high ferro train winter operation.
The mode of existing high ferro train bottom ice-melt snow removing mainly contains two kinds: a kind of mode is the temperature that the radiator heat-dissipation by arranging in train overhaul ditch improves train bottom local environment, accelerate the thawing speed of train bottom ice and snow, and in conjunction with the manually mode deicing of snow shovel ice.Which subject matter is: be difficult to ensure the requirement of 1 hour of car bottom ice-melt snow removing maximum duration, affect maintenance, the servicing work of train; The radiator arranging in service pit is not obvious to the effect of raising local ambient temperature, and the effect of ice-melt snow removing is slow, falls flat; And main deicing work is by manually completing, labour intensity is large, efficiency is low, and shovel snow is improper also easily to cause damage to car body.Another kind of mode is by adopting hot blast ice-melt snow removal system that hot blast higher temperature is delivered to train bottom, improve the speed of ice-melt snow removing, but because its hot blast air-supply arrangement does not have special design, just in train lower space, common air outlet is set, the thermal current of this air supply mode does not directly brush the ice and snow of train bottom, can not effectively cover train bottom ice and snow, or even do not cover at all, can not fully improve the heat exchange efficiency between hot blast and ice and snow, although the front a kind of mode of train peripheral temperature promotes higher, ice-melt speed increases, but do not give play to the optimum efficiency of hot blast ice-melt, cause thermal waste, the problem identical with front a kind of mode still exists in various degree.
Summary of the invention
The problem existing for the ice-melt snow removing of existing high ferro train bottom, the present invention releases a kind of for the high ferro train bottom hot blast air-supply arrangement of ice-melt snow removal system fast, by in a row with air outlet, the air-supply post of volume damper and air port wind direction four-way regulation locking device is arranged on a side of train ice-melt snow removing station, directly brush hot blast to train bottom, and make hot blast cover ice and snow comprehensively, the abundant contact heat-exchanging of hot blast and ice and snow, realize closely ice-melt snow removing fast, improve reliability and the validity of hot blast ice-melt snow removal system, promote the efficiency of hot blast ice-melt snow removal system, realize the requirement of technique, improve energy utilization rate.
What the present invention relates to is a kind of for the high ferro train bottom hot blast air-supply arrangement of ice-melt snow removal system fast, comprise the air-supply post that is arranged on train ice-melt snow removing station one side, air-supply post on the ground in one line, be evenly arranged, corresponding every joint train body arranges 11～13 air-supply posts.Air-supply post is fixed on ground and communicates with underground civil engineering air delivery duct, is connected with the hot blast unit in hot blast machine room by underground civil engineering air delivery duct.Hot blast unit in underground civil engineering supply air duct and hot blast machine room is the high ferro train bottom component part of ice-melt snow removal system fast, and ice-melt snow removal system also includes blowpipe backwind tube, return air inlet fast.
The air-supply post of described hot blast air-supply arrangement comprises cylinder, air outlet, wind direction four-way regulation locking device, volume damper, and air-supply column top arranges air outlet, and wind direction four-way regulation locking device is set in air outlet.
Dash drainage channel is set in the cylindrical shell of air-supply post and discharges water pipe.
The air outlet of air-supply post is bar shaped spout, and air outlet longitudinal center is provided with rotating shaft, is laterally symmetrical set angle adjustable breather vane in air outlet.
Wind direction four-way regulation locking device in air-supply post air outlet is made up of adjusting knob, drive link, gear, tooth bar, half moon fixed mount, lock screw.Wind direction four-way regulation locking device interlock air outlet, the adjusting of angle is spread in the left and right air-supply that realizes breather vane in the adjusting of the upper and lower wind direction of air outlet and air port.
The hot blast air-supply arrangement for the quick ice-melt snow removal system in high ferro train bottom the present invention relates to, hot blast by from air-supply post to train bottom ejection certain speed, mobile the increasing and the heat exchange of ice and snow and car body that utilizes wind pushing temperature and hot blast, and improve garage integrated environment temperature, realize the function of quick ice-melt snow.Train is stopped by fixing station after entering ice-melt storehouse, start the quick ice-melt snow removal system of hot blast, high temperature air directly brushes by hot blast air-supply arrangement and effectively covers bottom train, further improve the efficiency of hot blast ice-melt snow removing, shorten the ice-melt snow removing time, and then improve energy utilization rate, can significantly reduce artificial Snow removing amount, ensure that the longest ice-melt production time in railway car bottom is no more than 1 hour, meets technological requirement.
