The invention provides a mining forward shovel and a caterpillar band supporting device of the shovel. The caterpillar band supporting device comprises a supporting band and a supporting band mounting device. At least one vertical groove is arranged on the supporting band mounting device, and the grooves are arranged on the top of a caterpillar band frame in the longitudinal direction of the caterpillar band frame; an inserting plate is arranged on the lower portion of the supporting band and is inserted in the grooves, and a pin shaft which is horizontally arranged is arranged between the inserting plate and the grooves in a penetrating manner; and a limiting portion for limiting the supporting band from sliding in the longitudinal direction of the caterpillar band frame is arranged on the supporting band mounting device. According to the caterpillar band supporting device, the inserting plate of the supporting band is inserted in the grooves of the supporting band mounting device, and the limiting portion is used for limiting the supporting band, so that the phenomenon that after a pin shaft fails, the supporting band is loosened and falls off is avoided, and safety is improved.
Description
technical field [0001] The invention relates to the technical field of mining excavators, in particular to a crawler belt support device and a mining front shovel excavator equipped with the crawler belt support device of the present invention. Background technique [0002] The mining face shovel excavator is used to mine ore in the mine. It has a large bucket and its own weight is very heavy. Therefore, a crawler-type walking device must be used. [0003] The crawler tracks of the front shovel excavator used in mining are installed on the crawler frame. The top of the crawler frame is generally installed with a crawler belt device in contact with the crawler belt, and the crawler belt above the track frame is supported on the crawler belt device. The track support device includes a support belt and a mounting plate, the support belt is in contact with the lower surface of the track, and the mounting plate is fixedly arranged above the track frame. A pair of short boards a...
