AI Technical Summary

Technical Problem

The existing storage trolley is structurally unstable when the belt shifts, making it prone to tipping over. It also lacks an effective mechanical decoupling and buffering mechanism, resulting in mechanical vibration and operational instability.

Method used

The design employs a sliding connection between the floating frame and the chassis, combined with an eccentric cam mechanism and a hydraulic feedback mechanism, to achieve adaptive adjustment of dynamic load buffering and support force. Through the cooperation of damping rods and hydraulic circuits, it automatically corrects belt misalignment and enhances anti-rollover capability.

Benefits of technology

It effectively reduces the impact of belt misalignment on the frame, improves the structural stability and operational safety of the device under harsh working conditions, and ensures long-term operation in dusty and humid mine environments.

Abstract

The invention relates to the field of rubber belt conveying, and discloses a layering trolley for automatic deviation correction of a belt storage bin. The device comprises a frame, a floating frame slidably mounted on a sliding shaft on the inner wall of the frame, a supporting assembly and a stabilizing assembly. The floating frame lifts the belt body through the supporting rollers and generates translational displacement along with deviation of the belt body. The supporting assembly extrudes the resistance sleeve through the eccentric cam-shaped extrusion sleeve when the damping rod swings, so that the damping force is linearly increased along with the increase of the offset, and deviation energy of the belt body is absorbed. The stabilizing assembly moves relative to a piston rod fixed relative to the frame through a piston sleeve fixed to the bottom of the floating frame, and hydraulic oil in a main piston cavity is extruded. The sliding block drives the plugging head to mechanically plug the offset side oil way, hydraulic oil is guided to flow to the opposite side in a one-way mode through the connecting cavity, the auxiliary wheels on the opposite side are driven to extend outwards and press the side wall of the rail, and the reverse torque counteracts the overturning torque generated by gravity center offset. Automatic deviation correction and toppling resistance are achieved through mechanical linkage and hydraulic feedback.
