Abstract
The invention discloses a movable jack universal wheel unloading device, and belongs to the technical field of hydraulic mechanical equipment. The device comprises a jack and a trolley; at least one wheel guiding shaft is vertically arranged in the trolley; the upper end of the wheel guiding shaft penetrates a shell of the trolley; the part of the wheel guiding shaft out of the shell of the trolley is fixedly sleeved with a round nut; the lower end of the wheel guiding shaft is provided with a wheel assembly; a spring is sleeved at the periphery of the wheel guiding shaft; a sleeve is arranged at the periphery of the spring; the upper end of the sleeve is provided with a spring seat; a spring cup and a bearing are arranged between the lower end of the spring and the wheel guiding shaft; and a bush is arranged between the spring cup and the sleeve. The device is convenient to move and hardly damaged.
Description
Technical field
The invention belongs to the hydraulic machinery equipment technical field.
Background technology
Because the walking cardan wheel can not bear heavy lift, so mostly existing jack is stationary structure, when needing the conversion work place, then be used through instruments such as fork trucks, move inconvenient.
Summary of the invention
The objective of the invention is: provide a kind of and can conveniently move and non-damageable portable jack cardan wheel relief arrangement.
The objective of the invention is to realize like this: portable jack cardan wheel relief arrangement, comprise jack and dolly, vertical direction is provided with at least one wheel axis of guide in the dolly; And wheel axis of guide upper end passes the housing of dolly; The partial fixing that the wheel axis of guide passes the dolly housing is nested with a circular nut, and wheel axis of guide lower end is provided with vehicle wheel component, and wheel axis of guide periphery is nested with spring; The spring periphery is provided with sleeve; The sleeve upper end is provided with spring perch, between the spring lower end and the wheel axis of guide spring bowl and bearing is set, and between spring bowl and the sleeve lining is set.
The present invention under normal no-load condition, the own wt of spring-loaded dolly, the cardan wheel that protrudes little vehicle main body supplies walking to use; After dolly moves to control position, when jack begins to be loaded into certain load; The spring stress compression shortens; Just in the little vehicle main body of indentation, if at this moment continue to load to jack, the suffered power of cardan wheel no longer increases with jack load vehicle wheel component.Can walk when being implemented in zero load, when loading wheel unlikely again receive the heavy duty and impaired purpose.
In sum, conveniently moving of the present invention and not fragile.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the A-A part sectional view of Fig. 1.
Sectional schematic diagram when Fig. 3 is depressed by jack for the spring among Fig. 2.
The specific embodiment
Like Fig. 1,2, shown in 3, portable jack cardan wheel relief arrangement comprises jack 1 and dolly 2; Vertical directions are provided with at least one wheel axis of guide 3 in the dolly 2, and the wheel axis of guide 3 upper ends pass the housing of dolly 2, and the partial fixing that the wheel axis of guide 3 passes dolly 2 housings is nested with a circular nut 4; The wheel axis of guide 3 lower ends are provided with vehicle wheel component 12; The wheel axis of guide 3 peripheries are nested with spring 6, and spring 6 peripheries are provided with sleeve 7, and sleeve 7 upper ends are provided with spring perch 5; Spring bowl 10 and bearing 11 are set between spring 6 lower ends and the wheel axis of guide 3, between spring bowl 10 and the sleeve 7 lining 9 are set.
