Description

A kind of bulldozer is prevented Rolling device

Technical field

The utility model relates to the engineering machinery safety protection field, relates in particular to a kind of bulldozer anti-rollover device.

Background technology

The road vehicle overturn accident happens occasionally; Engineering truck is especially like this; The passengers inside the car's personal safety accident that causes thus is also increasing; People more and more is paid attention to the security performance of vehicle, and higher to the driver's cabin requirement of design passengers inside the car personal safety, requires vehicle when causing danger, also can effectively protect mental awareness.

In the prior art; A lot of vehicles all are equipped with anti-Rolling device, are example with the bulldozer, and the anti-Rolling device of the bulldozer cab of conventional in layout adopts four supporting structures; Support is positioned at four jiaos of driver's cabin, and will prevent that generally the after-poppet of Rolling device and fore-stock are installed on the wing plate.

The researcher finds the shortcoming below the existing anti-Rolling device existence of bulldozer in the practical study process: the anti-Rolling device weight of four supporting structures is big; And after-poppet and fore-stock are installed on the wing plate of bulldozer; This requires wing plate to have very high structural strength; And make the wing plate complex process that meets the demands, cost is high; Simultaneously, fore-stock is installed to be needed to reach the wing plate upper surface through thick bent plate from mainframe, and erection procedure is complicated.

The utility model content

The utility model embodiment provides a kind of bulldozer to prevent Rolling device; Have only two supports through use; And can be installed in the anti-Rolling device of bulldozer on the mainframe, make the mainframe of high structural strength effective support should prevent Rolling device, and should prevent that the Rolling device mounting process was simple.

The anti-Rolling device of the bulldozer of the utility model is installed on the mainframe of bulldozer, comprising: two supports (1), and the anti-canopy (2) that rolls, the anti-canopy (2) that rolls adopts the box structure of semi open model, and in the anti-canopy that rolls, at least one horizontal bar is arranged; Two supports (1) are connected with two relative frames of the anti-canopy (2) that rolls respectively, support the anti-canopy (2) that rolls, and the other end of support (1) is connected with mainframe.

Can find out that from above technical scheme the utility model embodiment has the following advantages:

Through using the anti-canopy that rolls of two stent support; Make that anti-Rolling device is simple in structure, overall weight alleviates, and should prevent that Rolling device was installed on the mainframe; The mainframe that utilization has high structural strength supports anti-Rolling device; Make the whole rigidity of structure of bulldozer strengthen, and support need not reach the wing plate upper surface from mainframe through thick bent plate, install simple.
