Abstract

The invention relates to the technical field of construction machinery equipment, in particular to a bulldozer cab anti-sand test bench, which includes a torque output device, a cab assembly fixing device and a sand blasting device, and the sand blasting device includes an air injection system and a sand and dust cycle system, the present invention can input torque to the cab assembly of the bulldozer and simultaneously simulate the working condition of the bulldozer to test the sand resistance performance of the cab assembly. The transmission shaft and cross bar perpendicular to each other make the torque output device Under the premise of not changing the orientation of the cab assembly, torque can be applied not only to the first two fixed points of the cab assembly, but also to the rear two fixed points, so as to avoid the need to use the driving force when changing the test point. Changing the position of the cab assembly once can reduce the operation of changing the position of the cab assembly twice when testing the six-point cab assembly.

Description

technical field [0001] The invention relates to the technical field of construction machinery and equipment, in particular to a sand-resistant test bench for a bulldozer cab. Background technique [0002] Bulldozers are earthmoving machines capable of excavating, transporting and discarding rock and soil, and are widely used in open pit mines. For example, it is used for building dumps, leveling car dumps, stacking scattered ore rocks, leveling work flats and construction sites, etc. It is not only used for auxiliary work, but also for main mining work. For example: stripping and mining of sand deposits, traction and boosting of scrapers and rock plows, and cooperating with other earth-moving machinery to reduce the height of stripping steps when there is no transportation mining method. [0003] During the working process of the existing domestic bulldozers, the intrusion of sand and dust into the cab is a stubborn problem that cannot be solved for a long time. [0004] ...
