A workpiece turning system with a safety limit device and a mining dump truck

Abstract

The invention discloses a workpiece turning system with a safety limiting device and a mining dump truck. The workpiece turning system includes a base, a workpiece, a safety limiting device, and a turning operating system; the workpiece is hinged on the base; One end of the operating system is hinged to the base, and the other end is hinged to the workpiece, and the workpiece is turned over on the base by turning over the operating system; a safety limit device is installed on the base, and when the workpiece is turned upwards After the angle is set, the workpiece is supported by installing a limit device. When the workpiece falls down to the base, the safety limit device returns to its original position, waiting for the next safety limit after the workpiece is turned up. The present invention can realize functions such as overturning, position limiting, and landing of workpieces. The present invention can be applied to the overturning and position limiting of similar parts such as cabs, hoods, and large boxes on vehicles, and can also be applied to similar large and small components in factories and workshops. The flipping of components is convenient, safe and reliable.

Description

technical field [0001] The invention relates to a workpiece turning system with a safety limit device, which belongs to the field of turning systems. Background technique [0002] The articulated dump truck has two front and rear frames. The front frame is equipped with a power source and a control center, and the rear frame is equipped with a loading device. The front and rear frames are connected by a hinge body. The rotation and tilt of the frame greatly reduce the torsional bending deformation of the frame and reduce the turning radius. Articulated dump trucks are widely used in small mining areas with limited space, rainy, muddy and rugged roads. [0003] The front frame of the articulated dump truck is equipped with engine, gearbox, cab, hydraulic system, fuel tank and other components, which are very compact. Many parts are located at the bottom of the cab, which is inconvenient for maintenance, so the cab is generally required to have a flip function. In the existi...

AI Technical Summary

Problems solved by technology

In the existing structure, after the cab is turned up, a safety bar is used to support between the bottom of the cab and the frame, and two pin shafts need to be manually installed for connection, which is cumbersome and unsafe to operate
