Abstract
A portal-type scraping plate reclaimer is used for conveying fire coals in a stock yard of a thermal power plant toward the direction of a boiler, and overcomes the shortcomings of massive scale of flying dusts, high noises, difficulties in realization of sealing operation of the stock yard and the like which exist in prior stacker-reclaimers. The portal-type scraping plate reclaimer comprises a track, a portal frame located on the track, wheels on the lower end of the portal frame, a wheel driving motor and reduction gears, a cantilever beam connected to the lower end of the portal frame in a hinged mode, a scraping plate chain type conveyor inside the cantilever beam, a cantilever beam luffing steel-wire-rope hoist positioned on the tops of the cantilever beam and the portal frame, a cantilever beam guiding track on the portal frame, a chute and a hopper at the output end of the conveyor, a ladder and a driver's cab on the portal frame and a control console in the driver's cab. The portal-type scraping plate reclaimer is convenient to realize a totally closed coal yard, avoids cross operation, and has good effects on material taking and mixing. A coal-retaining wall can be arranged unilaterally or a foundation can be formed into a sloping ground to increase the coal storage quantity of the coal yard effectively.
Description
Technical field
The invention belongs to Work machine, be specifically related to power plant boiler coal supply equipment.
Background technology
At present, in the coal-burning power plant, operate in the coal storage in coal storage place and get coal equipment and mostly be gate-type bucket-wheel stacker reclaimer or cantilever type bucket-wheel stacker-reclaimer.Aforementioned device, coal handling system belt, bedding plant, fire coal are gone into the storage between the treatment facility of stokehold, the transmission of taking is connected though can finish, but exist equipment occupation space to be difficult to realize the sealing operation in stock ground greatly, can not in conveying, finish coal-fired even mixing, the equipment unit running velocity is very fast, noise height, poor stability.
Summary of the invention
The purpose of this invention is to provide a kind of door type scratch board reclaimer, be used for thermal power plant's stock ground fire coal passing on to the boiler direction, overcome the sealing operation that is difficult to realize the stock ground that existing gate-type bucket-wheel stacker reclaimer or cantilever type bucket-wheel stacker-reclaimer exist, airborne dust is big, the high deficiency of noise.
Door type scratch board reclaimer of the present invention is by two parallel orbits that are laid on the edge, stock ground, be located in orbit portal frame across the stock ground, be installed on the end carriage of portal frame lower end wheel by rail supported, be installed in the wheel drive electrical motor on the end carriage, reductor, one end is hinged on system's belt one side portal frame lower end, length is with the cantilever beam of portal frame width, be installed in drag chain conveyor in the cantilever beam by rail groove, be connected the cantilever beam luffing steel wire rope winch between cantilever beam and portal frame top support, be fixed on the cantilever beam guide track on the portal frame, chute and hopper between drag chain conveyor mouth and system's belt, be installed in the ladder that leads to the portal frame top on system's belt one side portal frame, be installed in the driver's cab on system's belt one side portal frame, the operating console that is installed in the driver's cab is formed.It more than is basic technical scheme of the present utility model.
For optimizing structure, portal frame walking driver train adopts motor to add the form of hydraulic coupler acceleration and deceleration device among the present invention.Retarder is the hard flank of tooth retarder of horizontal parallel shaft.The scraper plate cantilever shalving is the cylindrical structure form, and portal frame and walking end carriage are the box-beam structure form.Be provided with high and low material level detecting sensor at scraper plate jib head.Cantilever shalving luffing angle limit limit sensors is arranged on the portal frame.
The invention has the beneficial effects as follows: be convenient to realize that coal yard is totally-enclosed, eliminate the influence of dust to surrounding environment, heap, reclaimer can work alone, effectively avoided cross-operation, it is effective to get the material mixing, realizes easily that for different material mixing gets material, getting material exerts oneself adjustable, easy to adjust, accurate.One-sidedly coal-stopping wall is set or the basis makes the sloping floor form, can increases the coal yard coal storage effectively.
Description of drawings
Accompanying drawing is integral structure figure of the present invention.
The specific embodiment
Consult accompanying drawing, lay two parallel orbits 1 at the edge, stock ground, chevron pointing portal frame 2 is seated on the track 1 across the stock ground, attachment rail supported wheel 3 on the end carriage of portal frame lower end, the wheel drive electrical motor is installed on end carriage, reductor, hinged under gantry system belt one side, length is with the cylindrical shape cantilever beam 4 of portal frame width, attachment rail groove in the cantilever beam, drag chain conveyor 5 is installed in the rail groove in cantilever beam, cantilever beam luffing steel wire rope winch 6 is installed between cantilever beam and portal frame top support, cantilever mounted beam guide track 7 on portal frame, chute and hopper between drag chain conveyor mouth and system's belt, the ladder 8 that leads to the portal frame top is installed on system's belt one side portal frame, driver's cab 9 is installed on system's belt one side portal frame, operating console is installed in the driver's cab.
