Description
Technical field
The present invention relates to coal railway transportation and load accessory equipment, specifically a kind of coal leveling machine.
Background technology
At present, coal railway transportation loading facilities is more aging and degree of automation is lower, coal is put into the dump forming after open-top car and is substantially adopted manually smooth from put coal bunker, this flat coal link is consuming time larger, a general recumbent bicycle needs 30-40 minute ability of 50 skilled flat coal works smooth good before dispatching a car, restriction production link, affects work efficiency.
The known coal leveling machine that is used for flat coal, mechanism is more complicated, and purchase and maintenance, use cost are high.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of simple in structure, and working service is coal leveling machine easily.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of coal leveling machine, comprise portal frame, coal scraper plate assembly, also comprise a crane, the left and right termination of described crane is clamped between the front baffle and rear frame of described portal frame, and the side relative with portal frame, left and right termination of crane is provided with rolling roller; Described coal scraper plate assembly is fixed on the lower end of described crane, and the upper end of described crane is connected with jacking system by steel rope.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
For making in coal scraper plate working process periodically vertical up and down movement, and during descending motion, by self gravitation, want to overcome the resistance of driving system, on coal scraper plate, making a crane is fixed together with it, the effect of crane has two: the one, and make coal scraper plate have enough weight, the 2nd, a left side for crane, right-hand member head-clamp is held between the front baffle and rear frame of portal frame, while making coal scraper plate work, there is stronger stability, before and after being unlikely to, rock, and crane and front, the plane of action of rear frame adopts rolling roller structure, in the process that can rise or decline at coal scraper plate, reduce the front baffle of crane and portal frame, the friction force of rear frame, make crane freely up and down.The present invention is simple in structure, and use and maintenance cost is lower, and its application can reduce artificial flat coal intensity, saves human cost, reduces the flat coal time, improves flat coal efficiency, guarantees that all kinds of coals transportations dispatch a car on schedule, realizes safety in production.
As preferably, the present invention further technical scheme is:
Described coal scraper plate assembly comprises coal scraper plate support, coal scraper plate, coal scraper plate support is that the centre of angle bar, channel-section steel welding has the steel structure frame of the strong structure of front impact, described steel structure frame and described crane are welded as a whole, forward and backward each two block welding of coal scraper plate is on described coal scraper plate support, and coal scraper plate bottom interval is provided with gap.Adopt the coal scraper plate of this spline structure, dump higher in the middle of making when flat coal, toward vehicle two side shiftings, reduces the stress concentration effect of coal scraper plate, is difficult for infringement coal scraper plate.The gap of coal scraper plate bottom, when scraping coal, part coal can pass through from gap, to reduce the working resistance of coal scraper plate, prevents that dump from forming lump and damaging coal scraper plate when long-pending too high.
Described jacking system comprises: three fixed pulleys that are arranged on portal frame top, be arranged on one-level movable pulley, the secondary movable pulley of portal frame one side, the axle of one-level movable pulley is connected with lifting hydraulic cylinder, and lifting hydraulic cylinder is by one-level movable pulley, secondary movable pulley, fixed pulley, wire rope pulling crane.Adopt such jacking system, having considered in place and lifting requirement and coal scraper plate working process needs rapid vertical to move, the driving system that selection is comprised of hydraulic ram and steel rope is controlled the motion of coal scraper plate, make steel rope move up and down open-top car side board correct position by effect traction coal scraper plate and the crane of movable pulley and fixed pulley, when car team moves, realize the flat coal function of coal scraper plate, by fixed pulley and I and II movable pulley are set, can make the stationarity of coal scraper plate up-and-down movement strengthen.
