Description
Technical field
The utility model relates to turbo-expander active wheel dismantling technology field, specifically is a kind of turbo-expander worker
Make the wheel extracting tool.
Background technology
The rotating speed of main shaft can reach 65000r/min during turbo-expander work, generally adopts the gas spring bearing.The general rubber hammer that adopts of dismounting at ordinary times knocks the impeller of blower side, takes off active wheel from opposite side then, not special-purpose extracting tool.This kind dismounting mode is not only operated inconvenience, and frays, sprains and abrade main shaft, bolt, active wheel surface easily, and the dismounting difficulty is big, skills involved in the labour require high.
Summary of the invention
The problem of easy damaged when utilizing conventional instrument to carry out the dismounting of decompressor active wheel in order to solve, the utility model provides a kind of turbo-expander active wheel extracting tool, and is easy to operate, prevents from fraying, sprains and abrade main shaft, bolt, active wheel surface.
The utility model is realized with following technical scheme: a kind of turbo-expander active wheel extracting tool, comprise two active wheel anchor clamps, and described active wheel anchor clamps are the L type; The movable assistant ejector pin of installing in the upper end of each active wheel anchor clamps, assistant ejector pin is provided with handle, and a housing also is installed on each assistant ejector pin, and a baffle plate is installed between the bottom of two housings, the one main push rod that moves up and down is installed on the baffle plate, and the upper end of main push rod is below assistant ejector pin.
It further is: main push rod passes spring and is installed on the baffle plate.
Described assistant ejector pin is installed in the upper end of active wheel anchor clamps by pitman shaft.
The beneficial effects of the utility model are: adopt this instrument that decompressor active wheel and gas bearing are carried out dismounting, and easy to operate, prevent from fraying, sprain and abrade main shaft, bolt, active wheel surface.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Among the figure: 1, pitman shaft, 2, housing, 3, handle, 4, assistant ejector pin, 5, the active wheel anchor clamps, 6, main push rod, 7, baffle plate.
The specific embodiment
As shown in Figure 1, a kind of turbo-expander active wheel extracting tool has two active wheel anchor clamps 5, and described active wheel anchor clamps 5 are the L type; The movable assistant ejector pin 4 of installing in the upper end of each active wheel anchor clamps 5, assistant ejector pin 4 is provided with handle 3, one housing 2 also is installed on each assistant ejector pin, one baffle plate 7 is installed between the bottom of two housings, the one main push rod 6 that moves up and down is installed on the baffle plate 7, and the upper end of main push rod is below assistant ejector pin.
Wherein, main push rod passes spring and is installed on the baffle plate.Described assistant ejector pin is installed in the upper end of active wheel anchor clamps by pitman shaft 1.
The course of work: earlier active wheel anchor clamps 5 are fixed in the slit of active wheel and bearing housing outer wall, the lower end of main push rod 6 contacts with the bolt that is positioned at the axial middle part of active wheel.The both hands handle 3 of holding with a firm grip makes its inside motion then, and under the effect of connecting axle 1, active wheel anchor clamps 5 are inwardly motion also, and are fixing tighter.In the process that handle inwardly moves, assistant ejector pin 4 moves downward the main push rod 6 of promotion and moves downward, and active wheel is taken off.
