Problems solved by technology

However, with the requirement of greater widening of the rotary drilling rig, as well as the increase in the length of the oil cylinder and the limitation of space, the inner space of the walking frame is limited, and the oil cylinder seat placed inside the walking frame is limited by the space, which not only cannot increase the widening stroke of the rotary drilling rig , nor can it adapt to the increase in cylinder length
[0004] Therefore, the form in which the oil cylinder seat is placed inside the walking frame can no longer meet the space requirements of the newly designed rotary drilling rig
In addition, since the cylinder seat is fixed by welding, it is not easy to replace

Abstract

The invention discloses a travelling frame, a travelling device and engineering machinery. The travelling frame is detachably provided with a cylinder base. A side plate of the travelling frame is provided with a fixed connecting hole used for fitting the cylinder base. The cylinder base is fitted outside the side plate of the travelling frame. Therefore, the cylinder base is disposed outside the travelling frame and is convenient to demount, the cylinder base and a cylinder are also convenient to change, external space can be fully utilized, and widening travel of the engineering machinery is enlarged.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a walking frame, a walking device and construction machinery provided with the walking frame. Background technique [0002] Generally speaking, according to the working characteristics of the rotary drilling rig, the rotary drilling chassis is designed as a retractable structure, which can be expanded during work to increase stability, and contracted during transportation to avoid over-limit transportation. Usually, the device that fixes the hydraulic cylinder is called the cylinder seat, and the traveling device of the rotary drilling rig includes the main frame, the traveling frame and the four-wheel belt installed on the walking frame. The four-wheel belt includes the driving wheel, the supporting wheel , guide wheels and tracks. Side walls are set around the walking frame. Wherein, the two ends of the hydraulic oil cylinder are respectively fixed on the oil cylinder se...
