Description
Technical Field
The present invention relates to a stay bar structure, and more particularly, to an upturned opening type part supporting structure and an engineering machine.
Background
The covers of construction machines are often provided with doors or windows that can be opened for repair and maintenance in order to repair or maintain the components in the covers. These doors or windows are opened in a side-turning manner or in an upturned manner, in which the doors or windows are in a high position after the upturned opening type doors or windows are opened, such as a rear door of a loader hood, and are widely used without occupying a maintenance space.
It is necessary to maintain the opened state of the flip-up type door or window using a stay structure after the opening. The existing support rod structure mainly comprises a support rod and a slide rail, wherein the first end of the support rod is rotatably connected with an upturning opening type component such as a door or a window, the second end of the support rod is connected with the slide rail, and the slide rail is fixed on a main body such as a machine cover. The sliding rail is provided with a vertical sliding groove, a clamping groove is formed in the first end, located at the high end, of the sliding groove, and the second end of the supporting rod is located in the sliding groove and can slide in the sliding groove. When the second end of the stay is located at the second end of the chute, the flip-up opening type member is in a closed state. When the upturning opening type component is upturned and opened around the upper edge of the upturning opening type component, the upturning opening type component pulls the support rod to move upwards, the second end of the support rod slides from the second end of the sliding groove to the first end in the sliding groove, and when the support rod moves to the first end of the sliding groove, the second end of the support rod slides into the clamping groove. The stay bar is limited due to the limit of the clamping groove, and the upturned opening type component is kept open. When the upturned opening type component is closed, the upturned opening type component needs to be slightly lifted upwards, the second end of the upturned opening type component leaves the clamping groove to enter the sliding groove, and then the upturned opening type component is turned downwards for closing.
In the existing stay bar structure, if the upturning opening type part is opened, the second end of the stay bar does not completely enter the clamping groove, the second end of the stay bar is in a false limit state, and if the main body is vibrated, the second end of the stay bar can slide into the sliding groove again, so that the upturning opening type part is suddenly closed. The sudden closing of the flip-up opening type part may injure maintenance personnel located under the flip-up opening type part to cause a safety accident.
