Self-braking support moving trolley

Abstract

Provided is a self-braking support moving trolley. The self-braking support moving trolley comprises a platform arranged on an I-shaped steel track in a sliding mode through a wheel axle. The I-shaped steel track comprises two pieces of I-shaped steel, and the two pieces of I-shaped steel are arranged in parallel and connected through a fixing plate. One of the two pieces of I-shaped steel is provided with a brake mechanism. The platform is provided with a lifting mechanism. The lifting mechanism comprises a bearing plate arranged above the platform, a lifting jack arranged between the bearing plate and the platform, two supporting guide barrels symmetrically arranged on the two sides of the lifting jack, and supporting guide rods in sliding connection with the supporting guide barrels correspondingly. The bearing plate is provided with a rotating mechanism. The self-braking support moving trolley has a high degree of automation and high moving efficiency, can adjust the position of fore-polings transported thereon, has higher adaptability, can be braked in time stably, and greatly improves the safety property and production efficiency.

Description

technical field [0001] The invention relates to the technical field of a mining frame moving vehicle, in particular to a self-braking type frame moving vehicle. Background technique [0002] The advanced supports used in coal mines need to cycle through the process of lowering, moving and raising the frames during use. The moving truck is an important tool for moving and transporting the advanced brackets. The reliability and safety of the moving truck transportation process is an important factor to ensure normal and continuous production. However, there are following technical problems in the existing rack-moving vehicles. [0003] First, the automation degree of the moving frame is low, and it needs to be moved by manpower during use, which is slow, inefficient, time-consuming and labor-intensive. [0004] Second, when the roadway space changes or encounters other mining equipment and the leading support cannot pass through, the moving vehicle cannot adjust the angle an...

AI Technical Summary

Problems solved by technology

[0003]First, the automation degree of the moving frame is low, and it needs to be moved by manpower during use, which is slow, inefficient, time-consuming and labor-intensive

[0004]Second, when the space of the roadway changes or encounters other mining equipment and the leading support cannot pass through, the moving vehicle cannot adjust the angle and position of the leading support. Manpower is required for adjustment, which greatly reduces the moving efficiency and thus reduces the production efficiency

[0005]Third, the brake of the moving vehicle is unstable and not timely, and the parking position is not accurate, especially when the moving vehicle passes through a roadway with a slope, it is difficult to stop. prone to accidents
