Abstract

The invention discloses a crane large cart mechanism and a crane. The crane large cart mechanism comprises a balance beam, a cart frame, wheels and a steering oil cylinder, wherein the balance beam, the cart frame and the wheels are connected in sequence; a fixed part of the steering oil cylinder is hinged to the balance beam, and a telescopic part of the steering oil cylinder is hinged to the cart frame and used for driving the wheels for steering through the cart frame; when the steering angle of the steering oil cylinder is 0 degree, the hinged center of the telescopic part is located in the first position; when the steering angle of the steering oil cylinder is 90 degrees, the hinged center of the telescopic part is located in the second position; when the axes of the wheels and the operation direction of a small cart mechanism of the crane are the same, the hinged center is located in the first position, the included angle between the connection line of the hinged center and the rotation center of the cart frame and the axis of the wheels is alpha which is smaller than 45 degrees, moreover, the included angle between the connection line of the second position where the hingedcenter can arrive and the cart frame and the axis of the wheels is beta which is larger than 45 degrees, and accordingly, the steering angle range of the steering oil cylinder can be -n degrees-90 degrees.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crane cart mechanism and a crane. Background technique [0002] As the traveling mechanism of the crane, the cart mechanism of the tire-type container crane is used to guide the whole crane to travel along the set direction. At present, the steering function of the cart mechanism of the tire-type container crane is mostly realized by the drive of the electric push rod or hydraulic cylinder. When the axis of the cart wheel is set to be parallel to the running direction of the crane trolley mechanism, the steering angle of the cart wheel is 0. °; when the axis of the cart wheel is set to be perpendicular to the running direction of the crane trolley mechanism, the steering angle of the cart wheel is 90°. In the prior art, the steering angle range of the cart wheel is 0° to 90° and the wheel only Can be positioned at 0° or 90°. [0003] Taking the patent with the a...
