AI Technical Summary

Technical Problem

The lack of effective limiting structures after the cab of existing construction machinery is overturned can cause the cab to overturn excessively or move in unexpected directions, affecting the safety and stability of the equipment.

Method used

The system employs a flipping assembly and a locking assembly, including a first lower suspension, a first upper suspension, and a limiting pin. The limiting pin is inserted into the lower pin hole and the upper pin hole. The locking assembly enables the cab to be fixed and separated from the frame in different angle states, ensuring that the cab can be flipped stably within a preset angle range.

Benefits of technology

It effectively prevents excessive tilting or unexpected movement of the cab, improves the safety and stability of construction machinery and equipment, facilitates maintenance and operation, and optimizes the transportation process.

Abstract

The utility model relates to the technical field of walking mechanical equipment, and particularly discloses a cab turnover assembly and engineering mechanical equipment, when the engineering mechanical equipment provided with the cab turnover assembly is overhauled, a locking assembly is switched to a separation state, at the moment, a cab can be driven to rotate around a pivot shaft relative to a frame, and the cab is turned over. When the included angle between the cab and the frame is the first preset included angle, the fixing piece fixes the included angle between the cab and the frame to be the first preset included angle, and at the moment, a worker can overhaul equipment below the cab. The included angle between the cab and the frame is fixed to be the first preset included angle through the fixing piece, the cab is prevented from being excessively turned over or moving in the unexpected direction, and then the safety and stability of engineering mechanical equipment are improved.
