A kind of turning-over changed mechanism
The present invention relates to a kind of mechanism on engineering construction car, specifically a kind of turning-over changed mechanism.
Generally in road construction field, in order to be repaired, be safeguarded, using corresponding to some sections more quickly
Work car, construction implementation is carried out in order to quickly rush to corresponding construction site.And before engineering construction, it is necessary to first by car
Body is fixed, and can ensure the stability of engineering construction.But in reality, because traditional car body and ground rely only on wheel
Arc point contacted, contact area is small to cause relative stiction smaller so that car body in construction stress, easily hair
Raw movement, causes construction to be easily out of order.
The content of the invention
Now in order to ensure that Construction traffic can keep stationary state in construction, the present invention proposes a kind of turning-over changed
The technical problems to be solved by the invention are realized using following technical scheme：
Side plate is mounted on the left of a kind of turning-over changed mechanism, including car body, the car body lower end, on the right side of lower end, each
Minute wheel pivot is rotatably installed, described minute wheel pivot is being connected with wheel away from car body one end on side plate.
The horizontally slidable mode of two side plates is arranged on car body lower end, and each side plate is matched somebody with somebody with corresponding minute wheel shaft clearance
Close, each side plate is connected with a hydraulic cylinder being packed on car body in one end close to car body center；Two minute wheel pivots it
Between there is the central shaft that is hinged and connected with both of which 180 degree plane.
It is fixed with suspension bracket, each suspension bracket on the left of the car body upper end, on the right side of upper end and is mounted on No. two hydraulic cylinders, often
Individual No. two hydraulic cylinders are respectively connected with is slidably mounted on band moving frame on car body and rectangular vertically, and the band moving frame bottom is welded
There is the push pedal being adapted with corresponding minute wheel pivot.
The central shaft and two minute wheel pivot threes are that cylindric and three cross section size is identical.
The push pedal lower surface is arc surface.
Present invention is mainly used for, will be whole in order to ensure that the stable of construction is carried out when car body is travelled to construction destination
Car body is fixed.
The beneficial effects of the invention are as follows：
Automaticity of the present invention is high, is coordinated by the relative connection of side plate, minute wheel pivot and central shaft, may be such that minute wheel
Axle is automatically changeb to by the state that is connected relatively with central shaft and is hinged rotatable state, reaches the way of contact on control wheel and ground
Conversion, and then increase contact area is played, car body is relatively fixed, facilitates the effect of engineering construction.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is front view of the invention；
Fig. 2 is Fig. 1 A-A sectional views.
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1 to Figure 2, on the left of a kind of turning-over changed mechanism, including car body 1, the lower end of car body 1, on the right side of lower end
It is mounted on that minute wheel pivot 3 is rotatably installed on side plate 2, each side plate 2, described minute wheel pivot 3 is away from car
The one end of body 1 is connected with wheel 4.
The horizontally slidable mode of two side plates 2 is arranged on the lower end of car body 1, and each side plate 2 is between corresponding minute wheel pivot 3
Gap coordinates, and each side plate 2 is connected with a hydraulic cylinder 5 being packed on car body 1 in one end close to the center of car body 1；Two
There is the central shaft 6 being hinged and connected with both of which 180 degree plane between minute wheel pivot 3.
It is fixed with suspension bracket 7, each suspension bracket 7 on the left of the upper end of car body 1, on the right side of upper end and is mounted on No. two hydraulic cylinders
8, each No. two hydraulic cylinders 8 are respectively connected with is slidably mounted on band moving frame 9 on car body 1 and rectangular, the bottom of band moving frame 9 vertically
End is welded with the push pedal 10 being adapted with corresponding minute wheel pivot 3.
The central shaft 6 and two threes of minute wheel pivot 3 are that cylindric and three cross section size is identical.
The lower surface of push pedal 10 is arc surface.
Present invention is mainly used for, will be whole in order to ensure that the stable of construction is carried out when the traveling of car body 1 to construction destination
Individual car body 1 is fixed, and fixed specific method is as follows：
Two hydraulic cylinders 5 are first passed through respectively to be pulled corresponding side plate 2 to the direction where the center of car body 1,
Until each side plate 2 is changed into being coordinated with central shaft 6 from originally with minute wheel pivot 3 coordinating, then by No. two hydraulic cylinders 8 by band
Moving frame 9, push pedal 10 are pushed down on, and push pedal 10 can extrude corresponding minute wheel pivot 3 so that minute wheel pivot 3, wheel 4 positioned at left side
90 degree of rotate counterclockwise, minute wheel pivot 3, the dextrorotation of wheel 4 positioned at right side are turn 90 degrees, i.e., two wheels 4 are by original circular arc
Face is fitted with ground to be changed into plane and is fitted with ground, equivalent to the contact area increased with ground, increases stiction, is risen
Fixed effect is arrived.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and that described in above-described embodiment and specification is the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improvement is both fallen within claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
