The hydraulic tensioning device provided by the utility model is reliable and stable for controlling a tensioning system for the scrapping plate chain of a lateral scraping plate reclaimer. The hydraulic tensioning device has the advantages that the structure is simple and practical; the tensioning force can be controlled stably; the mounting, the overhaul, the maintenance and the treatment are convenient; the work efficiency is improved; and the cost is reduced. The hydraulic tensioning device adopts hydraulic tensioning in which hydraulic oil serves as a medium, and is provided with the energy accumulator for ensuring the stability of tensioning pressure and realizing the shock absorption effect. The diameter of the oil cylinder can be selected flexibly according to requirements, so as to be suitable for occasions with a wide service pressure range and easiness in realizing larger tensioning force control.
Description
Technical field: the utility model relates to a kind of bulk solid loader and unloader tool, particularly a kind of scraper reclaimer.
Technical background: the main field of application of scraper reclaimer tool mainly is that heaps such as large-scale coal harbour, ore terminal, thermal powerplant, mine, steel plant, cement mill are got the stock ground; Being mainly used in bulk material carries; Reclaimer all is to drive the scraper plate revolution through flight chain material is scraped on the feed belt of getting conveying to the conveying great majority of all kinds of materials; To the tensioning degree of flight chain and reliable and stable control, can be direct influence reliable running and scraper plate service life of equipment.Traditional tensioning mode is that manual work comes the tensioning location through the mechanical screws nut, and this tensioning mode is impacted when equipment operation greatly, causes the damage of machine structural parts easily.So develop a kind of simple, reliable, practical scraper chain oil cylinder tightening device is very necessary.
Utility model content: for solving the problems of the technologies described above; The utility model proposes following technical scheme: a kind of reclaimer scraper chain tensioning hydraulic efficiency gear; Oil inlet of its high-pressure stop valve and pressure oil channel connection; And oil outlet links to each other with plunger cylinder, and the oil outlet of high-pressure stop valve also is connected with compression indicator, and the oil outlet of this high-pressure stop valve also is connected with energy storage through one-way throttle valve.Also can contact between the oil outlet of compression indicator and high-pressure stop valve pressure measurement flexible pipe and pressure measuring tie-in.Pressure measuring tie-in also can on be connected to the pressure monitoring element.Compression indicator is selected shock-proof pressure gauge for use.
Adopted following characteristics of the utlity model has of above technical scheme and beneficial effect:
Control for side formula scraper reclaimer flight chain clamping system provides a kind of reliable pulsation-free hydraulic tensioning structure.The utility model is simple and practical, is convenient to installation and maintenance and safeguards processing.Thereby increase work efficiency, reduced productive costs.What this utility model adopted is hydraulic tensioning, and medium is used hydraulic oil, and has the effect that energy storage is guaranteed the stable of tensioning pressure and realized bumper and absorbing shock.The oil cylinder cylinder diameter can be selected for use as requested flexibly, and the working pressure range that is suitable for is wide, and the occasion that also is well suited for big tensile force control is used.
Description of drawings: the utility model is done further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is the utility model reclaimer scraper chain tensioning hydraulic efficiency gear work system scheme drawing
Fig. 2 is the concise and to the point structural scheme of mechanism of the utility model reclaimer scraper chain tensioning hydraulic efficiency gear
The specific embodiment: side formula scraper reclaimer is got material system, elevator elevator system, rack section, fixed end beam, swing end carriage, rail system etc. by scraper plate and is partly formed.It is the main portion that this machine realizes getting the material function that scraper plate is got the material system.Actuating device is connected on the axle drive shaft through locking plate, and the sprocket wheel 10 on the axle drive shaft drives chain 9 and is fixed on scraper plate 11 cycle under the supporting of cantilever shalving on the chain 9, material is scraped got the center feed opening, falls on the belt conveyor being transported away.The elevator elevator system is to accomplish the mechanism that scraper plate is got material system luffing, is made up of bearing support and electric block, assembly pulley etc.After arm for taking material has whenever been got one deck material,, will expect taking-up successively by descend corresponding height (being the corresponding material degree of depth) and getting accordingly under the material running velocity of predetermined instruction.Scraper chain will guarantee enough tensile forces when circular flow.The tensioning degree of chain will be realized adjustment through this flight chain clamping system control plunger cylinder exactly in the utility model.At first the high-pressure stop valve on the pressure oil passage 1 is opened, the pressure oil that lets propulsion source supply enters into this system, the pressure display situation of the shock-proof pressure gauge 4 of observation.To note the air in the plunger cylinder 6 is drained only during first the use.On the plunger cylinder 6 exhausr port is arranged, reach suitable pressure after, high-pressure stop valve 1 is closed.After high-pressure stop valve 1 is closed, constitute a sealing pressurize chamber that comprises that plunger cylinder 6, energy storage 8, pressure detecting element 5 etc. are formed.Shock-proof pressure gauge 4 can be through pressure measuring tie-in 2 and pressure measurement flexible pipe 3 and system connectivity.The big I of plunger cylinder 6 operation pressures directly reads through shock-proof pressure gauge 4 during normal operation, or reads through pressure monitoring element 5 image data that are connected on pressure measuring tie-in 2 places.Pressure monitoring element 5 is a kind of remote pressure monitoring, thus assurance system reliable operation in the certain pressure scope.One-way throttle valve 7 is to be placed between energy storage 8 and the plunger cylinder 6 direct coupled passages, the speed of response in the time of can realizing plunger cylinder 6 work through one-way throttle valve 7 adjustment.When load variations, energy storage 8 can alleviate or eliminate fluctuation and the impact that produces, and makes the more steadily reliable of system works, realizes can alleviating the infringement to machine structural parts to greatest extent to the assurance of buffering, damping effect.This covering device be easy to install and on ordinary days in repair and maintenance.During use plunger cylinder 6 is fixed on the fixed support through the back end flanges, plunger cylinder 6 withstands on the fixing movable axis bearing of the sprocket wheel that can turn round, through realizing the tensioning requirement to scraper chain as direct power element.The loading adjustment of hydraulic pressure is controlled with external energy storage 8 valve members such as grade by the oil inlet pressure oil, realizes the assurance to buffering, damping effect.So just can realize reliably, steadily, work efficiently.
