Fig. 2 is the cross-sectional schematic of Fig. 1.
The specific embodiment
Core of the present utility model provides a kind of high-altitude operation engineering machinery, and its wheelspan can change under the different conditions.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please also refer to Fig. 1 and Fig. 2, Fig. 1 is the local structure scheme drawing of high-altitude operation engineering machinery that the utility model provides in a kind of specific embodiment; Fig. 2 is the cross-sectional schematic of Fig. 1.
In a kind of specific embodiment, the bottom of frame of high-altitude operation engineering machinery provided by the present invention is fixedly connected with vehicle frame sleeve 1, and vehicle frame sleeve 1 obviously is tubular, and prolongs the horizontal expansion of vehicle frame substantially.
In the left and right sides both ends open of vehicle frame sleeve 1 attaching parts is set all, promptly left attaching parts 21 and right attaching parts 22, left attaching parts 21 and right attaching parts 22 are gone into vehicle frame sleeve 1 inside from the two ends plug-in mounting respectively.
The outside (left side) of left side attaching parts 21 and the outside (right side) of right attaching parts 22 are separately installed with left wheel hub 31 and right wheel hub 32.The weight of associated components assembling finishing back high-altitude operation engineering machinery can be supported by tire.
The concrete structure of left side attaching parts 21 and right attaching parts 22 can have multiple, and the utility model is recommended to adopt form of sleeve, that is, left attaching parts 21 and right attaching parts 22 are respectively left coupling bush and right coupling bush, and both all are nested in the vehicle frame sleeve 1.
Because need the weight of carrying high-altitude operation engineering machinery, the shape of cross section of vehicle frame sleeve 1, left attaching parts 21 and right attaching parts 22 can be shapes such as polygon, ellipse, thereby obtains strained condition preferably.
There is the impulsive force of fore-and-aft direction in high-altitude operation engineering machinery when considering walking, simultaneously the also stability when improving the high-altitude operation engineering machinery walking can all be set to the shape of cross section of vehicle frame sleeve 1, left attaching parts 21 and right attaching parts 22 quadrangle as shown in Figure 2.
In addition, also can be mutually nested between left attaching parts 21 and the right attaching parts 22, for example, left side attaching parts 21 can be nested in the right attaching parts 22, thereby make and form suitable lap between the two, like this, the stability of high-altitude operation engineering machinery complete machine can obtain failure-free and guarantee.
A left side attaching parts 21 and right attaching parts 22 all movably plug-in mounting go in the vehicle frame sleeve 1, both all can stretch out or withdraw with respect to vehicle frame sleeve 1.Drive element can be set, so that provide the power that stretches out or withdraw for left attaching parts 21 and right attaching parts 22.
Particularly, described drive element can be an oil cylinder 4, and oil cylinder 4 obvious cardinal principles are in the horizontal extension of vehicle frame.
Oil cylinder 4 can be provided with two, and both can be arranged at respectively between left attaching parts 21 and the vehicle frame sleeve 1, and between right attaching parts 22 and the vehicle frame sleeve 1.
Oil cylinder 4 also can only be provided with one, and at this moment, as shown in Figure 1, oil cylinder 4 is arranged between left attaching parts 21 and the right attaching parts 22.
In addition, high-altitude operation engineering machinery provided by the utility model also comprises jacking apparatus, and described jacking apparatus can be lifted away from ground with wheel.
Described jacking apparatus specifically can be a jacking cylinder, also can be miscellaneous parts such as jack.
Latch 5 can be set, so that the relative distance between fixing left attaching parts 21 and vehicle frame sleeve 1, right attaching parts 22 and the vehicle frame sleeve 1; Elongation stopper 6 and retraction inhibiting device 7 can also be set, so that determine suitable elongation or withdrawal amount.As shown in Figure 2, slide block 8 can be set between sleeve, to reduce relative friction.
During work, at first tire is lifted away from ground by described jacking apparatus, can left attaching parts 21 be stretched out with right attaching parts 22 relative vehicle frame sleeves 1 by oil cylinder 4 then, therefore left wheel hub 31 and right wheel hub 32 also stretch out to both sides, wheelspan is strengthened, and the lateral stability of high-altitude operation engineering machinery is improved.When needing transition, can make left attaching parts 21 and right attaching parts 22 relative vehicle frame sleeve 1 withdrawals by oil cylinder 4, left wheel hub 31 and right wheel hub 32, wheelspan dwindles, thereby can satisfy the restriction of transportation means to specification of equipment, finishes the transition operation smoothly.
