Abstract

The invention discloses a portal bulk cargo raking device with double main rake arms and double auxiliary rake arms. The portal bulk cargo raking device comprises a herringbone portal, main and auxiliary (A end and B end) traveling devices, the double main rake arms and the double auxiliary rake arms, wherein the main rake arms and the auxiliary rake arms, which have the same power and the same raking quantity, are respectively arranged on the two sides of the herringbone portal, the double main rake arms and the double auxiliary rake arms are controlled by a same control system, that is, the double main rake arms lift and rake at the same time, and the double auxiliary rake arms also lift and rake at the same time, so that the overturning moment of the herringbone portal can be reduced, the section of the herringbone portal can be reduced effectively under the condition of the same raking quantity, and meanwhile, the cost of the control system and the number of personnel are not increased. Under the condition of the same specifications of rake arms, the maximal raking quantity can be twice of the current raking quantity.

Description

The bulk cargo gate-type raking apparatus of the two major-minor rake of band arm

Technical field: the invention belongs to the chemical plant field, is the mobile device of large-scale fertilizer plant.

Background technology:

Chemical fertilizer industry is one of important industry of chemical frbre industry and national economy, is the development priority of chemical frbre industry over the years.In the industry development process, the Fertilizer Industry organizational structure is adjusted and reorganization, being that fertilizer industry is enhanced productivity and energy utilization rate, the necessary means of environmental pollution of reducing by the production model of large-scale fertilizer enterprises replacement for small fertilizer enterprises, is the important measures that ensure the good and fast development of China's fertilizer industry.

Bulk cargo gate-type raking apparatus (abbreviation scraper) is the mobile device (see figure 1) of large-scale fertilizer plant maximum as the visual plant of chemical fertilizer production packing.General large-scale fertilizer plant all is provided with a large-scale chemical fertilizer storehouse in bulk, by travelling apron chemical fertilizer evenly is sprinkled in the storehouse in bulk when no terms of packing, by scraper chemical fertilizer is harrowed on the travelling apron when needs are packed again, and finishes quantitative package.

In recent years, along with carrying out in a deep going way of the adjustment of Fertilizer Industry organizational structure and reorganization, the maximization of chemical fertilizer production enterprise and the centralization equipment in its production process that makes also needs the upgrading that updates.The urea plant productive capacity develops to " 50-80 engineering " direction just by former " 30-52 engineering " (namely producing 300000 tons of synthetic ammonia/520,000 ton urea engineering per year) at present, and forward more extensive development such as " 70-120 engineerings ".And supporting scraper can't satisfy the demand of production with it, existing scraper becomes the short slab of chemical fertilizer production enterprise large-scale plant because tonnage is little, has not only seriously restricted the production efficiency of existing large-scale plant, and the energy consumption of scraper unit output value is higher, causes the bigger waste of the energy.

Summary of the invention:

Bulk cargo gate-type raking apparatus is made up of chevron pointing door frame and major-minor (A, B two ends) running gear, and it is mobile with running gear that the same side is hung with major and minor rake arm on the chevron pointing door frame, on the rake arm board-like raking apparatus is installed.During work, to the same side convey materials, the size of its traffic capacity mainly promotes by the rake charge level that improves the rake plate long-pending (namely harrowing width and the height of plate) the board-like raking apparatus on the major and minor rake arm with bulk cargo.Its major defect: the one, harrowed the restriction of sheet material material, the rake charge level of rake plate is long-pending can not to be amplified arbitrarily, has limited the lifting of scraper rake material ability; The 2nd, in the same side of door frame, the deadweight of rake arm will produce capsizing moment with the mobile major and minor rake arm of chevron pointing door frame, so cross section that must increase chevron pointing door frame causes the increase of material.The present invention arranges the identical major and minor rake arm of specification simultaneously in chevron pointing door frame both sides---the bulk cargo gate-type raking apparatus of the two major and minor rake arms of band, it effectively solves the problem that produces capsizing moment on the one hand, effectively solve the stressed problem of chevron pointing door frame, the rake material ability of scraper be can promote on the other hand energetically, the maximization of chemical fertilizer production enterprise and centralization satisfied to the equipment needs.

The specific embodiment:

The bulk cargo gate-type raking apparatus of the two major and minor rake arms of band reaches two major and minor rake arms by chevron pointing door frame and major-minor (A, B two ends) running gear and forms, the major and minor rake arm of equal-wattage and rake material amount is installed in both sides on the chevron pointing door frame, the major and minor rake arm of its pair is controlled by same control system, i.e. two main rake arm lifting simultaneously and rake material, secondary rake arm is lifting simultaneously and rake material also, can reduce the capsizing moment of herringbone door frame like this, when harrowing the material amount on an equal basis, can effectively reduce the cross section of chevron pointing door frame, not increase control system cost and personnel amount simultaneously again.Under the identical situation of rake arm specification, its drag material amount can reach the twice of present rake material amount.

Claims

1. the bulk cargo gate-type raking apparatus of the two major and minor rake arms of band is made up of chevron pointing door frame and major-minor (A, B two ends) running gear, the major and minor rake arm of equal-wattage and rake material amount is installed in chevron pointing door frame both sides, the major and minor rake arm of its pair is controlled by same control system, i.e. two main rake arm lifting simultaneously and rake material, two-pack rake arm is lifting simultaneously and rake material also, can reduce the capsizing moment of herringbone door frame like this, when harrowing the material amount on an equal basis, can effectively reduce the cross section of chevron pointing door frame, not increase control system cost and operating personal quantity simultaneously again.Under the identical situation of rake arm specification, its drag material amount can reach the twice of present rake material amount.

2. the bulk cargo gate-type raking apparatus of the two major and minor rake arms of band according to claim 1 is characterized in that the major and minor rake arm in chevron pointing door frame both sides installation equal-wattage and rake material amount.

3. the bulk cargo gate-type raking apparatus of the two major and minor rake arms of band according to claim 1 is characterized in that controlled by same control system at the major and minor rake arm of its pair, i.e. two main rake arm lifting simultaneously and rake material, and two-pack rake arm is lifting simultaneously and rake material also.
