Abstract
The utility model relates to a coal leveling machine and specifically discloses a hydraulic coal leveling machine for coaling train wagons. The hydraulic coal leveling machine comprises a portal and a coal pushing plate and is characterized by further comprising a vertically movable cylinder, a tilting plate cylinder, and a tilting plate cylinder pressure relief pump, wherein the lower end of a vertically movable cylinder body is hinged to a lug on a stand column of the portal, the upper end of a piston rod is in universal hinge to a moving support of the coal pushing plate, the moving support is movably connected with a rail on the stand column of the portal, a tilting plate cylinder body is installed on the moving support, one end of the piston rod is hinged to a rotation shaft of the coal pushing plate, two ends of the rotation shaft of the coal pushing plate are supported by the moving support, and the tilting plate cylinder pressure relief pump is installed above the coal pushing plate. A pressure relief cylinder is installed at the top of the coal leveling machine; when the coal pushing plate is blocked by the train wagons, hydraulic oil in the hydraulic cylinder flows back to an adjusting cylinder through a pressure relief valve due to overlarge stress, and the pushing plate is turned up with the wagons; when the pushing plate passes through wagon gaps, the hydraulic cylinder applies new pressure to the adjusting cylinder again to guarantee continuous normal coal conveying of the coal pushing plate.
Description
Technical field
The utility model relates to a kind of coal leveling machine, the hydraulic coal leveling machine that specifically a kind of train wagon is coaling and used.
Background technology
Due to train wagon, coalingging is to carry out operation in the advancing of railway carriage, and is difficult to before avoiding the phenomenon in hole after heap, so need equipment to carry out flat coal operation in daily entrucking process.Old coal leveling machine adopts motor, reductor, band-type brake as propulsion source, because flat coal plate insertion train top coal is excessively dark, band-type brake burns because resistance is excessive, in use because appearring in misoperation, steel rope comes off, once steel rope comes off, just can cause the coal leveling machine accident of stumbling, impact is normally produced.Mechanical power source coal leveling machine, owing to tending to cause wagon coal unbalance loading by deadweight and operation scheme, causes ature of coal dispute, can not adapt to and produce outward transport requirement.
Summary of the invention
The hydraulic coal leveling machine that the purpose of this utility model provides train wagon that a kind of equipment failure rate is low to coaling and use.
The utility model comprises door frame, coal-pushing plate, characterized by further comprising up and down oil cylinder, turnover panel oil cylinder, turnover panel oil cylinder pressure release pump, journal stirrup on the lower end of up and down cylinder block and the column of door frame is hinged, the mobile support saddle universal hinging of piston rod upper end and coal-pushing plate; Track on the column of mobile support saddle and door frame is flexibly connected; Turnover panel cylinder block is arranged on mobile support saddle, and one end of piston rod and the rotating shaft of coal-pushing plate are hinged, and the two ends of the rotating shaft of coal-pushing plate are supported by mobile support saddle, passes the top that oil cylinder pressure release pump is arranged on coal-pushing plate.
By hydraulic power unit, provide propulsion source, utilize hydraulic ram to control rising and falling of coal-pushing plate.
Also increased nitrogen cylinder, when propulsion source loses, pressure thus cylinder provides, and guarantees to have operated.
The utility model compared with prior art has the following advantages:
Can adopt hydraulic power unit that propulsion source is provided by hydraulic coal leveling machine, utilize hydraulic ram to control rising and falling of flashboard, bear resistance large, hoisting speed is fast, universal connection is used in junction, hydraulic ram top, even if there is stumbling coal leveling machine accident, also can not affect the leak tightness of oil cylinder.And at top installation pressure release oil cylinder, when coal scraper plate is subject to train railway carriage and stops, hydraulic ram is due to stressed excessive, in cylinder, hydraulic oil can flow back to and regulate in cylinder through blowdown valve, turnover panel can be dug with railway carriage, and during through railway carriage space, hydraulic ram can be given and regulate cylinder to inject new pressure again, guarantee that spillplate continues the normal coal of hanging, this oil cylinder pressure unloading size is that the resistance when scraping coal work regulates according to scene.
Hydraulic coal leveling machine effectively solves the flat coal problem of train, guarantees that ature of coal meets the requirements, and equipment failure rate is low, is convenient to safeguard, can the F.F. of effective guarantee train go out soon, is coal outward transport establish a firm foundation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is birds-eye view of the present utility model.
In figure, 1. door frame, 2. coal-pushing plate, 3. up and down oil cylinder, 4. turnover panel oil cylinder, 5. turnover panel oil cylinder pressure release pump, 6. journal stirrup, 7. mobile support saddle, 8. track, 9. rotating shaft.
The specific embodiment
The utility model comprises door frame 1, coal-pushing plate 2, also comprise up and down oil cylinder 3, turnover panel oil cylinder 4, turnover panel oil cylinder pressure release pump 5, journal stirrup 6 on the lower end of up and down oil cylinder 3 cylinder bodies and the column of door frame is hinged, mobile support saddle 7 universal hingings of piston rod upper end and coal-pushing plate; Track 8 on the column of mobile support saddle 7 and door frame 1 is flexibly connected; Turnover panel oil cylinder 4 cylinder bodies are arranged on mobile support saddle 7, and the rotating shaft 9 of one end of piston rod and coal-pushing plate 2 is hinged, and the two ends of the rotating shaft 9 of coal-pushing plate 2 are supported by mobile support saddle 7, pass the top that oil cylinder pressure release pump 5 is arranged on coal-pushing plate 2.
By hydraulic power unit, provide propulsion source, utilize hydraulic ram to control rising and falling of coal-pushing plate.
Also increased nitrogen cylinder, when propulsion source loses, pressure thus cylinder provides, and guarantees to have operated.
While running into too large resistance, coal-pushing plate can automatic turning, does not damage other mechanisms.When coal-pushing plate is subject to train railway carriage and stops, turnover panel oil cylinder is due to stressed excessive, in cylinder, hydraulic oil can flow back to and regulate in cylinder through blowdown valve, push pedal meeting is dug with railway carriage, during through railway carriage space, hydraulic ram can give regulate again cylinder inject new pressure, guarantees that coal-pushing plate continues the normal coal of hanging, and this oil cylinder pressure unloading size is that the resistance when scraping coal work regulates according to our scene.
Actuator cylinder is fixed on door frame, strengthens oil cylinder stability.When coal-pushing plate movable is convenient to stumble train railway carriage, do not damage connection pedestal.
Universal connection is used in junction, up and down oil cylinder top, even if there is stumbling coal leveling machine accident, also can not affect the leak tightness of oil cylinder.
