Description
Technical field
The present invention relates to flat coal technical field, particularly a kind of rotatable coal leveling device.
Background technology
The main railway that relies on of coal in China transportation, Railway Coal transportation volume accounts for national coal total gross traffic more than 70%, and along with coal production construction emphasis moves westwards and moves northward, Railway Coal transportation burden is more and more heavier, therefore it is extremely urgent to improve the conveying efficiency of coal.The loading of coal is a key factor that affects conveying efficiency, yet in loading process, loose coal charge forms taper dump in compartment, cause the floating coal charge of pine to leak outside in transportation, and the compartment of unbalance loading also brings serious threat to the train safe of running at high speed.Therefore it is necessary before transportation coal, to coal car, carrying out smooth.At present coal bin smooth had to artificial smooth and mechanical planarization.
Artificial smooth is to rely on manual operation plow-shape instrument that taper dump is shakeout, but in the motion process loading at coal charge, be difficult to carry out manual work, must train must be stopped, having had a strong impact on conveying efficiency, and there are many unsafe factors, make that artificial smooth labour intensity is large, efficiency is low.
Platform coal leveling device is widely used at home, and basic functional principle is: coal leveling device is as you were, along with the mobile and smooth coal in compartment.Or compartment is motionless when smooth coal, at coal leveling device, to put down to after outside efficient range, compartment moves a segment distance, and coal leveling device can move on guide rail, the compartment in flat next segment limit.So repeatedly, reach the object of flat coal car railway carriage or compartment coal.In the process of relatively moving, utilize hydraulic actuating cylinder lifting breaking down shovel, be bulldozed the coal charge in each compartment.Because train headstock is than the high 1 meter of left and right of the height in compartment, therefore, when train headstock passes through, require 1 meter of the whole raising of coal leveling device, for hydraulic actuating cylinder, the stroke that increases by 1 meter is not only consuming time very long, and makes installation more complicated, greatly reduces the work efficiency of coal leveling device.
Summary of the invention
In prior art, the invention provides a kind of rotatable coal leveling device, the unnecessary lifting of hydraulic actuating cylinder in the time of can effectively avoiding headstock to pass through.
The technical solution used in the present invention is: a kind of rotatable coal leveling device, comprise the inboard beams and the outer beams that are arranged at rail both sides, girder is set up at described inboard beams and outer beams top, the hoist cylinder of vertical direction is installed on girder, the piston rod end fixed installation breaking down shovel of described hoist cylinder, described outer beams top vertical is installed slewing arrangement, girder outer end connection rotary device.
Described rotatable coal leveling device, described slewing arrangement comprises outer sleeve, top flange dish is installed at described outer sleeve top, the inner axis of installing, flange in the bottom dish is installed in described axis bottom, two deep groove ball bearings are installed between described axis sidewall and outer sleeve inwall, described axis top suit thrust baring, described thrust baring top is higher than axis end face.
Described rotatable coal leveling device, described breaking down shovel left and right end portions is installed pulley, mates the vertical mounting guide rail of pulley on described girder.
Described rotatable coal leveling device, arranges oblique floor stringer in described outer beams.
In the present invention, the slewing arrangement being installed in outer beams rotates girder in the horizontal direction, when train headstock passes through, from home position half-twist, make girder be placed in train way one side, after locomotive engine passes through girder, again girder is rotated to home position, can effectively avoid the unnecessary lifting of hydraulic actuating cylinder like this, increase work efficiency, reduce device loss.
Guide rail can make hydraulic actuating cylinder more smoothly drive breaking down shovel up-and-down movement, increases the stability of device, the impact of resistance on hydraulic actuating cylinder while avoiding flat coal.

In figure: 1-inboard beams, 2-outer beams, 3-girder, 4-hoist cylinder, 5-breaking down shovel, 6-pulley, 7-guide rail, 8-slewing arrangement, 9-ground, 21-floor stringer, the circular steel plate of 31-, 32-H type shaped steel, 81-top flange dish, 82-bearing carrier ring, 83-packing ring, 84-outer sleeve, 85-axis, 86-flange in the bottom dish, the upper deep groove ball bearing of 87-, 88-thrust baring, deep groove ball bearing under 89-.
The specific embodiment
As Fig. 1, inboard beams 1 and outer beams 2 are set up in respectively rail both sides, and wherein outer beams 2 is positioned at platform one side, and its side arranges oblique floor stringer 21, and slewing arrangement 8 is installed at top.Described inboard beams 1, outer beams 2, floor stringer 21 are fixed on ground by ground 9.Described girder 3 vertical directions are installed hoist cylinder 4, the piston rod end fixed installation breaking down shovel 5 of hoist cylinder 4 lower ends, described breaking down shovel 5 left and right end portions are installed respectively pulley 6, and girder 3 the right and lefts are vertically installed the guide rail 7 mating with pulley 6, on pulley 6 installations and guide rail 7.
As Fig. 2, described slewing arrangement 8 comprises outer sleeve 84, described outer sleeve 84 welded top top flange dishes 81, the inner axis 85 of installing, described axis 85 bottom welding flange in the bottom dishes 86, flange in the bottom dish 86 is installed on outer beams 2 tops, between described axis 85 sidewalls and outer sleeve 84 inwalls, install deep groove ball bearing 87 and lower deep groove ball bearing 89, described axis 85 top suit thrust barings 88, described thrust baring 88 tops are higher than axis 85 end faces, between described thrust baring 88 and outer sleeve 84, bearing carrier ring 82 is set, between the inner ring of described upper deep groove ball bearing 87 and thrust baring 88, packing ring 83 is set.
As Fig. 3, the circular steel plate 31 that size is mated with top flange dish 81 is installed in the external side end of described girder 3 bottom, perforate on described circular steel plate 31, and perforate size position and top flange dish 81 match.During assembling, circular steel plate 31 is bolted with top flange dish 81, thereby girder 3 is connected with slewing arrangement 8.
When having coal car need to flat coal time, first, by the outside half-twist of girder 3, after train headstock passes through, then rotate back to home position.When girder 3 rotates, top flange dish 81 rotates with outer sleeve 84 simultaneously, and the weight of thrust baring 88 carrying rotatable parts also can be rotated, stablizing when upper deep groove ball bearing 87 and lower deep groove ball bearing 89 can keep rotatable parts to rotate.
While starting flat coal, the piston rod of hoist cylinder 4 stretches out downwards, drives breaking down shovel 5 to the home position of retracting after flat coal after assigned address, then next railway carriage is carried out to flat coal operation.In breaking down shovel lifting process, pulley 6 and the guide rail 7 at two ends, left and right can guarantee the steady of breaking down shovel lifting, and avoids resistance in flat coal process to produce diametral load to piston rod.
