[0002] In order to meet the requirements of coal safety certification, the crawler-type two-arm tunneling trolley cannot use the traditional aluminum propulsion beam, but a steel propulsion beam. The propulsion beam structure is an integrated extruded beam. Since the inner concave part of the propulsion beam is too small, the front roller cannot be placed vertically, so the front roller can only be laid flat. After laying it flat, a device needs to be added to the roller to fix the roller shaft to increase its strength. At the same time, in order to prevent the wire rope on the roller from detaching, we proposed an anti-detachment device for the roller of the crawler-type two-arm tunneling trolley.
