AI Technical Summary

Technical Problem

When the inside of the dump truck car is filled with heavier car, the gravity of the car supporting the output shaft of the hydraulic cylinder is easily damaged, which affects the service life of the dump truck.

Method used

A flip mechanism for dump trucks is designed. By opening a limiting groove on the surface of the fixed seat and setting elastic devices and limiting devices on both sides of the surface of the rotating seat, the restoration elastic force of the first spring and the installation block in the shape of a triangular block are used to limit the rotation direction of the rotating seat, ensuring that the carriage is supported by multiple points when flipping.

Benefits of technology

The flip mechanism extends the service life of the dump truck when flipping through multi-point support, avoids damage caused by single point support of the hydraulic cylinder output shaft, and improves the stability and safety of flipping of the car.

Abstract

The utility model provides a turnover mechanism for a dumper. The turnover mechanism comprises a bottom plate panel, and the rotating seat is fixedly connected to the bottom of the bottom plate panel. According to the turnover mechanism for the dumper, the twelve limiting grooves are formed in the surface of the fixed seat, the elastic devices and the limiting devices are arranged on the two sides of the surface of the rotating seat, the mounting blocks are pushed to be embedded into the limiting grooves through the restoring elastic force of the first springs, and the fixed seat is limited; the device is simple in structure and high in practicability, limiting and supporting effects are achieved through the mounting block when the rotating seat drives the carriage to turn over, the carriage of the dumper is supported through the output shaft of the hydraulic cylinder when turned over, and the carriage of the dumper is supported through the output shaft of the hydraulic cylinder when turned over. A plurality of devices support the carriage to turn over, so that the service life of the dumper during turning over is prolonged.
