AI Technical Summary

Technical Problem

The existing steel wire rope fixing structure of the cargo box of mining dump trucks is complex, takes a long time to install, is labor-intensive, and the steel wire rope is prone to deformation, which reduces its impact resistance and is inconvenient to replace.

Method used

The system combines built-in and external double wedge fasteners with a telescopic system. It automatically adjusts the stress length of the wire rope through pressure detection and control, uses the self-locking property of the wedges to fix the wire rope, reduces the number of wire ropes, and achieves automatic adjustment of the wire rope by folding back and looping through the support guide.

Benefits of technology

It simplifies the installation and disassembly process of wire rope, improves its impact resistance, ensures the reliability and safety of wire rope, avoids the loss of impact resistance due to deformation, and has wide applicability.

Abstract

The application discloses a steel wire rope bearing automatic adjusting device and method, a cargo compartment and a mine dump truck. Multiple rows of steel wire ropes are arranged on both sides of the cargo compartment. The two ends of the steel wire ropes are fixed by built-in double wedge block fasteners. The middle parts of the steel wire ropes are supported on the side beams and the guide bodies. The built-in double wedge block fasteners at one end of the steel wire ropes are provided with external double wedge block fasteners above the built-in double wedge block fasteners. The oil cylinders of the two moving wedge blocks are arranged on the upper and lower sides of the external double wedge block fasteners. The pressure of the steel wire rope bearing is measured by a pressure sensor. The hydraulic system is controlled by a control system. The length of the rope stress can be automatically changed according to the change of the steel wire rope tension, so that the adjustment of the steel wire rope tension is realized. Compared with the prior art, the device is easy to disassemble and install, the length of the rope stress can be freely changed, the performance is reliable, and the device has wide practicability.
