Abstract

The invention discloses a leveling mechanism for engineering machinery in the field of construction engineering of railway lines, comprising a leveling turntable, a leveling cylinder, a support bracket for the leveling cylinder, and an adjustable locking device, wherein the leveling turntable is located on the support bracket for the leveling cylinder and is hinged with the support bracket of the leveling cylinder; one end of the leveling cylinder is hinged with the leveling turntable, while the other end is hinged with the support bracket of the leveling cylinder; and the adjustable locking device is connected between the leveling turntable and the support bracket of the leveling cylinder. According to the leveling mechanism for engineering machinery, the problems that working devices or articles are difficult to pack and a double-arm crane cannot rotate when the outer rail of a railway line is ultrahigh, and trains are easy to derail when a hydraulic leg is put away can be solved.

Description

technical field [0001] The invention relates to a construction machine for railway line construction, in particular to a leveling mechanism of the construction machine. Background technique [0002] At present, many of the construction machinery for railway line construction use a truck-mounted crane to lift the working device or object, and it will lift the working device or object to the working position for operation. It is hoisted to the working position by jib crane for rail welding operation. The rail welding car is supported by hydraulic outriggers when it is working at super-elevation on the outer rail of the railway line, while the rail welding car will tilt at the curve, the distance between the two booms of the double-arm crane is limited, and the welding machine is The lower capacity collides with the boom, which makes it difficult to retract the welding machine, and increases the slewing resistance of the double-arm crane, resulting in the slewing motion or los...
