Description
Technical field
The utility model relates to a kind of improvement of operating unit of semi-door type scratch board reclaimer.
Background technology
Semi-door type scratch board reclaimer is a kind of continuous, efficient bulk solid loader and unloader tool, is widely used in the industrial trades such as cement building material, coal, harbour, electric power, metallurgy, iron and steel, chemical industry.For pre-homogenizing and the heap of limestone, coal, iron ore, iron fine powder and auxiliary material are got.
The structure of semi-door type scratch board reclaimer is derived by hoisting crane, and both sides have walking end carriage, and is that a side beam floats, and opposite side end carriage is fixed, and span is larger, even also wants large compared with the span of heavy-duty machine, generally all at 25 meters~60 meters.So exist equally deflection operation and gnaw rail phenomenon in actual production.For the above-mentioned phenomenon occurring in hoisting crane, generally adopt horizontal guide sheave to add without wheel flange wheel mechanism; Although this mechanism has solved the rail problem of gnawing, for fear of the generation that occurs derailment occurring, clamp structure still need to be set on end carriage, as secondary safeguard procedures.
The stressed pattern of semi-door type scratch board reclaimer and hoisting crane makes a big difference.Hoisting crane under normal circumstances, be only subject to the hoisting force of vertical direction, and the stressed of semi-door type scratch board reclaimer is not such.Semi-door type scratch board reclaimer mainly by swinging end walking end carriage, door frame (being equivalent to crossbeam or cart in hoisting crane), scraper plate reclaimer system, fixed end walking end carriage, hoisting mechanism, walk on stage, several parts such as control system form.Two walking end carriages are arranged on respectively on the track of both sides, stock ground, and the upper support of end carriage door frame.One end of scraper plate reclaimer system and fixed end walking end carriage are hinged, and the other end is hung on door frame by assembly pulley.The impulsive force producing in scraper plate reclaimer system working process is vertical with the direction of end carriage, that is to say, in reclaiming process two end carriages especially fixed end beam constantly bearing horizontal side force (the suffered wheel load of horizontal wheel).Therefore, produce very large side force in the time of real work middle scraper feeding, the side force of bearing compared with heavy-duty machine is much bigger.
This just causes semi-door type scratch board reclaimer in operational process, uses the common horizontal wheel of hoisting crane that the phenomenon of derailing easily occurs, and has serious potential safety hazard.
Summary of the invention
The utility model is exactly for the problems referred to above, provides one can effectively bear semi-door type link plate reclaimer side force, derailment occurring can not occur, the operating unit of the semi-door type scratch board reclaimer that safety is good.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises wheel carrier, the both sides of wheel carrier are provided with axle sleeve, are provided with rotating shaft in axle sleeve, and described rotating shaft lower end is provided with horizontal wheel by bearing, it is characterized in that: described axle sleeve upper end is provided with butt flange, both sides, described rotating shaft upper end are provided with breach, are provided with briquetting in breach, and briquetting fixes with the butt flange of described axle sleeve by attaching screw; The surrounding of described butt flange is provided with at least four location gap, on described wheel carrier, is provided with at least one fixture block corresponding to location gap.
As a kind of preferred version of the present utility model, described axle sleeve is set to excentric sleeve, and the surrounding of described flange is uniform is provided with at least eight location gap.
As another kind of preferred version of the present utility model, the both sides of described wheel carrier are provided with two groups of axle sleeves, rotating shaft, bearing and horizontal wheel.
The beneficial effects of the utility model: 1, the utility model is realized the connection of axle sleeve and rotating shaft by the briquetting in breach in rotating shaft, butt flange is connected with wheel carrier with fixture block by location gap again, makes the utility model can bear huge side force; Therefore, the utility model is more suitable for semi-door type scratch board reclaimer.
2, due to constructional feature of the present utility model, the impact of the suffered side force of the utility model is little, and high safety has been avoided the generation of derailment occurring.
3, because the track length of semi-door type scratch board reclaimer operation is larger, the straightness accuracy of track is difficult to ensure; Therefore, if being fixedly installed on wheel carrier, two horizontal wheel can produce the phenomenon of gnawing tooth; The utility model, by eccentric axle sleeve is set, can rotate axle sleeve to correct position according to the deviation of track in advance, makes distance and track perfect cooperation between horizontal wheel, avoids gnawing the generation of tooth phenomenon; Improve product stability and service life.
The ability of 4, bearing side force in order further to improve the utility model, the both sides of the utility model wheel carrier arrange four horizontal wheel altogether; Ensure safety factor of the present utility model.
