Description
Technical field
The utility model relates to a kind of belt conveyer with liquid viscosity controllable start brake integration device.
Background technology
At present, the technical measures of belt conveyer controllable start employing both at home and abroad mainly contain following several kinds:
(1) adopts variable speed fluid coupling, can accomplish to prolong cranking time, realize that empty load of motor starts, improves the full load starting performance of conveyer.But there is following weak point in this system: 1. hydraulic coupler is when normal operation; 3～5% slippage is generally arranged, have the loss of 3～5% driving efficiency this moment, and conveying machinery long-term work when mostly long; The impeller disk cal val is big, wastes a large amount of energy; 2. variable speed fluid coupling can't realize that transmitting ratio is 1 through-coupling operating condition; 3. there is a unsettled transition region all the time in variable speed fluid coupling in starting process, makes starting ability also undesirable; When 4. realizing producing in serial form, the major part commonality is poor between the different hydraulic coupler of power; 5. the volume of hydraulic coupler is bigger, and system control performance and control accuracy are relatively poor.
(2) adopt frequency converter, frequency converter has soft starting characteristic preferably, can not be fit to be applied to explosion-proof frequency converter that mine down-hole use but also develop at present at home and abroad; For high pressure, high capacity squirrel-cage motor, adopt the frequency converter investment greatly in addition, reliability is also relatively poor, and needs to adopt special motor; Frequency converter can produce powerful signal interference simultaneously, influences the normal operation of other electrical control equipment.These have all limited the application of frequency converter in commercial production.
(3) hydro viscous drive.It can improve the transmission serviceability of heavy-duty machinery greatly.But complex manufacturing technology, processing technology is had relatively high expectations, and cost is bigger with investment, and maintenance cost is higher.Be not suitable for China's national situation and to the existing simple technological change of heavy duty equipment.Say that from structural arrangement CST places liquid-viscosity driving device on the retarder slow-speed shaft, structural volume is huger, and the control of temperature rise is easier to.
At present, the technical measures of belt conveyer controllable brake employing both at home and abroad mainly contain following several kinds:
(1) disc brake apparatus.Mainly form by mechanical Pan Zha and controlled hydraulic station; Its principle of work is through drg scratch diskette to be applied friction brake force to produce lock torque; Size through oil pressure in the Hydraulic Station adjustment drg can be adjusted positive pressure, thus the size of adjustment lock torque.Hydraulic Station has adopted electro-hydraulic proportional control technology, so the lock torque of brake system can be adjusted according to need of work automatically, realizes good controllable brake.Shortcoming is that the brake disc linear velocity can not be too high, otherwise is prone to spark.
(2) hydraulic brake system.Drive Hydraulic Pump through conveyer system and also can produce moment, this moment, hydraulic oil pump produced onesize damping moment to conveyer, when damping moment is enough big, will brakes conveyer and realize braking.Hydraulic braking can be divided into two kinds of braking models, and a kind of is the pressure regulation braking, and another kind is the speed governing braking.Hydraulic brake system can be accomplished desirable downward belt conveyor braking deceleration through control oil pressure or flow.Because Hydraulic Pump is in the high-speed operation state when long, quick abrasion, the life-span is short, and in braking procedure, a large amount of braking heats are taken away by hydraulic oil, and through the water-filled radiator heat radiation, have increased the system of setting up; When the oil temperature is too high, the hydraulic package easy fault, fluid further influences the reliability of hydraulic control system because the cycle and the temperature traverse of big flow are easy to go bad simultaneously; Simultaneously when conveyer is decided car, because the leakage of Hydraulic Pump and hydraulic efficiency pressure system must add the push rod band-type brake specially and decide automobile-used; More increased the complexity of system.
(3) hydraulic brake.When the turbine of impeller disk fixedly the time, the huge resisting moment of high velocity liquid stream that will drive pump impeller make its deceleration.This is the principle of work of hydraulic-braking system.Hydraulic-braking system mainly is made up of the hydraulic brake impeller disk and the hydraulic pressure cooling controller of band pump impeller, turbine.Can change the size of lock torque through the adjustment filling amount, realize the controllable brake of belt conveyer.Because pump impeller and turbine are not rigid attachment, the life-span of hydraulic brake impeller disk is long.Shortcoming is that hydraulic-braking system can not be braked zero-speed to conveyer, when pump impeller speed is lower than 400r/min, must use mechanical brake braking, its same hydraulic brake system of fluid control cooling system, same too high or oily easy fault when poor of oil temperature that exists.
(4) liquid viscosity brake equipment.Report to " wet multi-disc brake " was once arranged both at home and abroad, and at present wet multi-disc brake is used on the engineering truck more, and the research of " wet multi-disc brake " is started from the U.S..Early stage work major side overweights experimental investigation, studies the frictional behavior of wet multi-disc brake and power-transfer clutch through test results.In recent years, progressively carrying out about the research of a series of basic theories aspects such as wet multi-disc brake principle of design, structure optimization and mechanism of fracture and constantly perfect.The basic functional principle of the utility model is similar with it, but because the operating characteristic of belt conveyer is different with engineering truck, the design theory of wet multi-disc brake not exclusively is applicable to belt conveyer.Do not see research report abroad to belt conveyer " liquid viscosity brake equipment ".
The utility model organically is combined into one liquid viscosity controllable start technology with the controllable brake technology, has realized the first Application on belt conveyer.
