The invention discloses a self-lifting mechanism of a caterpillar band of a hydraulic drill rig. A guide wheel shaft is mounted inside a frame sliding groove after penetrating through a guide wheel; one end of a guide wheel push rod is connected with the guide wheel shaft; the other end of the guide wheel push rod is connected with a push rod sliding block; the push rod sliding block is connected with a frame through a guide wheel spring; a driving wheel is mounted on the frame; the caterpillar band is mounted between the driving wheel and a guide wheel; a thrust wheel is hinged to a thrust wheel push rod; the thrust wheel push rod is mounted on the frame; a push rod sliding block inclined groove is formed in the push rod sliding block; the tail end of the thrust wheel push rod is connected with the push rod sliding block inclined groove. The self-lifting mechanism has the benefits that the passing capacity of the self-lifting mechanism is improved in a mode of passively shrinking the guide wheel and lifting the thrust wheel, the environment application property and the climbing property for large-size barriers of the hydraulic drill rig are greatly improved, and meanwhile the self-lifting mechanism is simple in structure and free of extra control mechanism.
Description
technical field [0001] The invention relates to the field of construction machinery mechanisms, in particular to a crawler self-elevating mechanism of a hydraulic drilling vehicle. Background technique [0002] The working environment of hydraulic rock drilling rigs is harsh, and most of them are in rugged mountains and rocks. How to increase the passing capacity of hydraulic drilling rigs under limited conditions has become a problem that restricts the development of hydraulic drilling rigs. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a crawler self-elevating mechanism for a hydraulic drilling rig. [0004] The technical solution of the present invention is: hydraulic drilling car crawler self-elevating mechanism, including vehicle frame, vehicle frame chute, guide wheel, guide wheel shaft, crawler belt, driving wheel, guide wheel push rod, guide wheel spring, push rod slider, Push rod slider chute,...
