Abstract
The utility model provides an eccentric pin structure for adjusting a connecting rod, which comprises an eccentric pin. A guide blade arm of a hydroelectric generator is connected with the connecting rod through the eccentric pin. The eccentric pin structure is simple in structure, reasonable in design, convenient in use, simplified in connecting mechanism, convenient in mounting and maintaining and low in manufacturing cost. An error of a vertical guide blade face of a hydroelectric generating set is conveniently adjusted.
Description
Technical field
The utility model belongs to the hydroelectric facility field, specifically is a kind of cam pin structure of adjusting connecting rod.
Background technique
In the assembling of hydro-turbo generator set water guide mechanism,,, a cover mechanism must be set satisfy the demand for guaranteeing the synchronism of all stators because processing and installation errors can not guarantee the synchronous opening and closing of all stators.The length of traditional left and right sides spiral adjustment connecting rod is with the facade error of control stator; Connecting rod is with the nut of jaws and is had right-and-left threaded connecting screw rod by two and forms; The screw rod that is rotatably connected changes the length of connecting rod, thereby can control the gap of vertical surface of stator, and this kind adjustment stator facade error structure is complicated; Operating difficulties, manufacture cost is higher.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of cam pin structure of adjusting connecting rod.
A kind of cam pin structure of adjusting connecting rod is characterized in that it comprises cam pin, guide vane lever and connecting rod, is connected by cam pin between guide vane lever and the connecting rod.
Said cam pin comprises connecting pin, taper pin, bolt, and said taper pin is arranged on connecting pin below, and said bolt is arranged on the taper pin below, said taper pin and said bolt on same center line, and with connecting pin not on a center line.
Said bolt is provided with pulls mouth.
A kind of cam pin of adjusting connecting rod of the utility model has characteristics simple in structure, reasonable in design, easy to use, it has simplified bindiny mechanism, makes things convenient for installation and maintenance, and low cost of manufacture can be adjusted hydraulic generator unit stator facade error easily.
Description of drawings
Fig. 1 is the overall schematic on the hydraulic turbine generator that is installed in of the utility model a kind of cam pin structure of adjusting connecting rod;
Fig. 2 is a kind of cam pin schematic representation of adjusting the cam pin structure of connecting rod of the utility model;
Among the figure, 1-guide vane lever; 2-cam pin; 3-connecting rod; 4-connecting pin; 5-taper pin; 6-pull mouth; 7-bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 2; A kind of cam pin structure of adjusting connecting rod of the utility model comprises cam pin 2, guide vane lever 1 and connecting rod 3, and cam pin 2 comprises connecting pin 4, taper pin 5, bolt 7, and taper pin 5 is arranged on connecting pin 4 belows; Bolt is arranged on taper pin 5 belows; Taper pin 5 and bolt 7 on same center line, and with connecting pin 4 not on a center line, bolt is provided with pulls mouthfuls 6.During work, as shown in Figure 1, the guide vane lever 1 of hydraulic turbine generator is connected through said cam pin 2 with connecting rod 3, and through mouthful 6 rotation cam pins 2 of pulling on the bolt 7, thereby the length of change connecting rod 3 realizes the adjustment of hydraulic generator unit stator gap of vertical surface.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection domain of the utility model.
