Flexible guardrail of mining dump truck

Abstract

The invention discloses a flexible guardrail of a mining dump truck. The flexible guardrail comprises a guardrail assembly, a guardrail pressing plate and mounting bolts; the guardrail assembly comprises a plurality of guardrail split bodies and connecting bolts, and the guardrail split bodies are connected through connecting bolts; an arc section is arranged in the middle of the guardrail pressing plate, long mounting holes are formed in connecting sections on the two sides of the arc section, and a flanging structure is arranged at the bottom of the guardrail pressing plate; and the guardrail pressing plate and the mounting bolts are used for mounting the bottom end of the guardrail assembly on the platform assembly. While the welding workload is reduced, the installation difficulty andthe large assembly stress caused by large errors of a welding structure are effectively overcome.

Description

technical field [0001] The invention relates to a mining dump truck, in particular to a flexible guardrail for a mining dump truck. Background technique [0002] Mining dump truck is the main transportation equipment in open-pit mines. This equipment has the characteristics of high load, large overall outline size, and running on bumpy roads in mines all the year round. Mining dump trucks usually have a platform assembly above the engine to install cabs, rearview mirrors, air filters, mufflers and other components, and the platform assembly is also the main operating platform for daily maintenance and maintenance. Since the operators have to come and go frequently on the platform, and the platform is higher than the ground, it is required to install a safety guardrail structure around the platform to ensure the safety of the people passing by. [0003] Traditional guardrails are usually formed by bending and welding steel pipes, skirting boards are welded along the edge of ...

AI Technical Summary

Problems solved by technology

Because the guardrails of this structure are all steel pipe bending, space butt joint and rigid welding structure, the manufacturing error is relatively large, and there are welding deformation and bending springback, and several installation supports are not on the same plane. In this way, it is difficult to guarantee the installation accuracy in actual production.

The site usually needs to be partially knocked or squeezed to assemble with the platform, resulting in a large stress concentration on the installed guardrail itself, coupled with the frequent bumps and impacts of mining dump trucks on the mine road, making this guardrail It is easy to break and open welding, which has a great negative impact on the safety and attendance of mining dump trucks
