Problems solved by technology

After long-term use, the gap between the first positioning pin 14-1 and hole 3 121 becomes larger, and the first positioning pin 14-1 is prone to fall off, which affects production safety
[0012] Simultaneously, due to the space position relation, the hole 5 131 on the fixed leg 13 is far

Abstract

The invention discloses an outrigger locking mechanism used for mobile construction machinery. In the invention, an outrigger of the mobile construction machinery comprises a first movable outrigger (2), a second movable outrigger (3) and a fixed outrigger (4); the outrigger locking mechanism comprises a locking part (6) and a first locking hole (21) which is matched with the locking part (6) and arranged at the outer end of the first movable outrigger (2); a first mounting hole (41) is arranged at the outer end of the fixed outrigger (4); and when both the first movable outrigger (2) and the second movable outrigger (3) are retracted into the fixed outrigger (4), the locking part (6) is inserted into the first locking hole (21) and the first mounting hole (41) and has a scheduled distance from the second movable outrigger (3). The outrigger locking mechanism is easy to operate and can effectively enhance locking efficiency. The invention also provides the mobile construction machinery comprising the outrigger locking mechanism and then the reliability is enhanced.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a leg locking mechanism for mobile construction machinery. In addition, the present invention also relates to a mobile construction machine comprising the above-mentioned outrigger locking mechanism. Background technique [0002] Mobile construction machinery is commonly used in modern industry, and its outriggers generally include fixed outriggers and movable outriggers. According to the length of the movable outriggers, the outriggers of mobile construction machinery can be divided into three states: fully extended state, half extended state and fully retracted state. When mobile construction machinery is running on the road, its movable outriggers need to be retracted to the maximum extent, generally in a fully retracted state, to improve safe passage; when working, the movable outriggers need to be stretched out, generally in a half state Extended state or fu...
