Problems solved by technology

Specifically, in the first solution, after the folding struts are unfolded, the top cover is at the corresponding opening angle, which is difficult to adjust further; in the second solution, when a shorter chute is set on the support body, the top The maximum opening angle of the cover is limited; in the third solution, the telescopic stroke of the gas spring is relatively limited, the maximum opening angle of the top cover is small, and when the gas spring is extended, the opening angle of the top cover is difficult to further adjust
In addition, in the first solution, the space required for folding and unfolding is larger

Abstract

The invention relates to the technical field of machine top covers and discloses a machine top cover support structure and an excavator. The machine top cover support structure comprises a support body, a machine top cover and a support rod. The support rod comprises a first rod part, a second rod part telescopically matched with the first rod part and a locking structure disposed between the first rod part and the second rod part. The free end of one of the first rod part and the second rod part is rotationally connected with the support body, and the free end of the other of the first rod part and the second rod part is connected with a first rotary shaft movably disposed on the machine top cover or the free end of one of the first rod part and the second rod part is connected with a second rotary shaft movably disposed on the support body, and the free end of the other of the first rod part and the second rod part is rotationally connected with the machine top cover. When the machine top cover support structure is used, the machine top cover can have wide range and opening angle convenient to adjust by adjusting the extending length of the support rod and the position of one end of the support rod on the machine top cover or the support body.

Description

technical field [0001] The invention relates to the technical field of a top cover, in particular to a support structure of a top cover and an excavator. Background technique [0002] In the excavator, in order to avoid the harsh working environment from affecting the main engine, a cover is generally provided outside the main engine. In order to facilitate maintenance and daily maintenance, an opening is provided on the cover corresponding to the top of the main engine, and a A matching top cover is rotatably connected to the frame on one side of the opening. [0003] In the prior art, there are mainly three types of support methods for the top cover: the first is to use a folding strut mechanism, wherein one end of the folding strut is hinged to a support (such as a strut) on the frame, and the other end is It is hinged with the top cover, and the opening of the top cover can be realized by controlling the unfolding of the folding struts. The second is to adopt a sliding...
