Further, described supporting leg urceolus and the supporting leg inner core side of being tubular construction.
Further, four outer sides of described supporting leg inner core are all connected with a wearing plate.
Further, what the length of described wearing plate was not more than support oil cylinder piston rod stretches out stroke.
Further, described wearing plate is copper alloy edge graphite piece.
Further, described supporting leg urceolus and Rear frame one-body molded.
Further, the angle between described supporting leg urceolus and Rear frame is 40-50 degree.
Further, be provided with area bottom supporting leg inner core and be greater than the backing plate supporting inner core cross-sectional area.
Further, described leg structure is positioned at the below of work large arm jointed shaft.
By above technical scheme, the utility model has following technique effect compared to prior art:
1, when support oil cylinder extends, drive supporting leg inner core to stretch out, wearing plate slides along on supporting leg outer tube inner wall, in whole moving process, piston rod is hidden in supporting leg inner core, and wearing plate is hidden in supporting leg urceolus, wearing plate and support oil cylinder bar all do not expose, and are beneficial to and increase its reliability, more durable.
2, the leg structure side of employing tubular construction, only has 1 direction degree of freedom, supports more stable.
3, leg structure is arranged in work large arm and supports bottom, and rear car width takes up room less, increases the space for maintenance of trailing wheel, improves the convenience of maintenance.
