Description
Technical field
The utility model relates to a kind of turbine gate mechanism transmission device.
Background technique
The water distributor transmission device of at present conventional water turbine generally comprises control ring, duplex arm, pivoted arm, link pin and break pin etc., wherein one end of pivoted arm is fixed on the guide vane teunnion of water distributor, one end of duplex arm is connected with the other end of pivoted arm by break pin, the other end of duplex arm is connected with control ring by link pin, described water distributor: the current that make to enter before runner form rotation, and can change the incident angle of current, when generator load changes, with it carry out adjust flux, during normal and accidental shutdown, with it block current, described duplex arm also also claims connecting rod, it is the transmission part for connecting control ring and pivoted arm, can change by the length of adjusting it rotation angle of stator, break pin is one of water turbine four large protection mechanisms, signal generator is equipped with in break pin inside, when stator blocks when motionless for some reason, first break pin is cut off and is protected other transmission part, guarantee unit safety stable operation, what described duplex arm generally adopted is ear handle drive mechanism, when but the connecting plate of pivoted arm is connected with the duplex arm of ear handle drive mechanism, because making link pin and break pin, the existence of ear handle structure is subject to the effect of additional bending moment, and because link pin and break pin in the vertical direction are not subject to any constraint, in gate linkage course of action, the impact of the factors such as the moving and connecting rod own level deviation of controlled Huantiao, often there is violent swashing in link pin and break pin, its amount of swashing generally can reach 10mm～20mm, link pin and break pin acutely swash and have directly caused following three aspects: adverse effect: 1, axle sleeve lifting surface area is reduced and unbalance stress, cause axle sleeve heavy wear, even there is local extrusion-deformation (the axle sleeve replacement cycle shortens), 2, make break pin be subject to the effect of huge additional bending moment, cause maximum stress on its disrumpent feelings cross section to reach the ultimate strength of material itself, the moment that finally causes break pin acutely to swash at duplex arm ruptures (at power station operation initial stage, the quantity of the improper fracture of every machine break pin is 10 left and right), if 3 break pins are scurried out completely, will inevitably cause stator out of control, serious words also can cause adjacent two stator break pins to cut off, or cause that unit is out of control.
Model utility content
The purpose of this utility model be for the deficiencies in the prior art provide a kind of simple in structure, prevent from altering on break pin and link pin, with low cost, prevent the turbine gate mechanism transmission device that unit is out of control.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of turbine gate mechanism transmission device, comprise control ring, duplex arm, pivoted arm, link pin and break pin, one end of described duplex arm is connected with pivoted arm by break pin, the other end is connected with control ring by link pin, the upper end of described break pin is provided with the upper end cap playing the role of positioning that diameter is greater than break pin diameter, the lower end of described break pin is provided with pin rod hole, described break pin is located the lower end of described break pin by the locating stud being inserted in described pin rod hole, and the end cap that diameter is greater than link pin diameter is installed on the lower end of described link pin.
Described break pin and described link pin are arranged on described duplex arm by nylon sleeve respectively.
The surface layer of described break pin and described link pin is provided with stainless steel lining.
The surface layer of described break pin and described link pin is provided with oxidation film layer.
Adopt said structure, the utlity model has following advantage:
1, the link pin that the break pin that the utility model is connected with pivoted arm by improvement duplex arm and duplex arm are connected with control ring, by the upper end cap and the pin rod hole that increase on break pin, thereby prevent from altering on break pin thereby insert locating stud by upper end cap with in pin rod hole, by the end cap installed below link pin and with screw rod, fix, prevent from altering on link pin, thereby prevent from altering on break pin and link pin caused cutting off;
2, in addition by stainless steel lining being set at the surface layer of link pin and break pin, so both increased the strength character of link pin and break pin, can prevent from causing because of humid environment again the generation of body corrosion, reduce the frictional force that axle sleeve and break pin, axle sleeve and link pin relative motion produce, reduce the frequency that break pin is cut off;
3, break pin and link pin are arranged on described duplex arm by nylon sleeve respectively, because nylon sleeve has that mechanical strength is high, bearing capacity is large, wear resistance is good, anti-aging, long service life, do not hinder the advantages such as antithesis, therefore can improve the mechanical property of this device.
