Abstract
The utility model relates to a kind of carriage walking device, comprises dolly, hydraulic actuating cylinder and guide rail, is provided with wheel bottom described dolly, and wheel is placed on guide rail; Described hydraulic actuating cylinder is connected with sprocket wheel, and described sprocket wheel is located on slide rail, and chain is connected with sprocket wheel, and one end of chain is fixed on one end of dolly, and the other end of chain is fixed on base.The beneficial effects of the utility model are: increase chain gear apparatus, make sprocket wheel play the effect of movable pulley, and under the stroke that dolly specifies, actv. reduces hydraulic cylinder travel, increases the stability of hydraulic cylinder works.
Description
Technical field
The utility model relates to a kind of carriage walking device.
Background technology
Carriage walking device mainly contains motor and hydraulic-driven two kinds, and hydraulic-driven is simpler than motor-driven structure, and hydraulic-driven mostly is hydraulic actuating cylinder and is connected directly between on dolly.When dolly stroke is larger, cause hydraulic cylinder travel comparatively large, working stability declines.
Utility model content
The purpose of this utility model is to provide a kind of carriage walking device, to overcome currently available technology above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of carriage walking device, comprise dolly, hydraulic actuating cylinder and guide rail, be provided with wheel bottom described dolly, wheel is placed on guide rail; Described hydraulic actuating cylinder is connected with sprocket wheel, and described sprocket wheel is located on slide rail, and chain is connected with sprocket wheel, and one end of chain is fixed on one end of dolly, and the other end of chain is fixed on base.
Further, the number of described wheel is 2.
Further, described hydraulic actuating cylinder is positioned at below dolly.
The beneficial effects of the utility model are: increase chain gear apparatus, make sprocket wheel play the effect of movable pulley, and under the stroke that dolly specifies, actv. reduces hydraulic cylinder travel, increases the stability of hydraulic cylinder works.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is a kind of carriage walking apparatus structure schematic diagram described in the utility model embodiment.
In figure:
1, dolly; 2, chain; 3, slide rail; 4, sprocket wheel; 5, hydraulic actuating cylinder; 6, guide rail; 7, wheel; 8, base.
Detailed description of the invention
As shown in Figure 1, a kind of carriage walking device described in the utility model embodiment, comprises dolly 1, hydraulic actuating cylinder 5 and guide rail 6, is provided with wheel 7 bottom described dolly 1, and wheel 7 is placed on guide rail 6; Described hydraulic actuating cylinder 5 is connected with sprocket wheel 4, and described sprocket wheel 4 is located on slide rail 3, and chain 2 is connected with sprocket wheel 4, and one end of chain 2 is fixed on one end of dolly 1, and the other end of chain 2 is fixed on base 8.The number of described wheel 7 is 2; Described hydraulic actuating cylinder 5 is positioned at below dolly 1.
During concrete use, hydraulic actuating cylinder 5 drive sprocket 4 rotates, and sprocket wheel 4 drives chain 2, and chain 2 drives dolly 1, and dolly 1 is moved on guide rail 6, and slide rail 3 pairs of sprocket wheels 4 play the guiding role.
After increasing sprocket wheel 4, sprocket wheel 4 plays the effect of movable pulley, and under the stroke that dolly specifies, actv. reduces hydraulic actuating cylinder 5 stroke.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
