Experimental equipment for shield tail brush

Abstract

The invention belongs to the technical field of the shield tail brush performance detection and mainly relates to experimental equipment for a shield tail brush. The experimental equipment comprises a hydraulic pump station (3-4), an abrasive resistance testing mechanism (3-5), an elastic testing mechanism (3-2) and a PLC (Programmable Logic Controller) (3-11), wherein the abrasive resistance testing mechanism (3-5) comprises an experiment bench (3-1), a hydraulic motor (4-9), a hydraulic motor output gear (4-4), a pivoting support (3-8), a concrete brush table (3-9) and a lead screw-nut mechanism (3-6); the elastic testing mechanism (3-2) comprises a shield tail brush fixing device (10-1), a portal frame (10-6), a telescopic outer sleeve (10-5), a telescopic inner sleeve (10-4), an oil cylinder (10-7) and a pressing plate (10-3). The experimental equipment for the shield tail brush realizes testing on the performance of the shield tail brush products and prevents security risks caused by improper selection of the products.

Description

technical field [0001] The invention belongs to the technical field of shield tail brush performance detection, and mainly relates to shield tail brush experimental equipment. Background technique [0002] like figure 1 The shield machine 1-1 shown is a kind of tunnel tunnel excavation construction in soft soil, which has a metal shell 1-3, and the whole machine and auxiliary equipment are installed in the shell, and the soil body 1-2 is excavated under its cover. It is a tunnel construction machine that can form the tunnel at one time, such as , earth muck transportation, complete machine propulsion, and concrete segment 1-11 installation. In order to prevent groundwater, outer soil, lining back grouting 1-11, etc. from flowing into the tunnel, usually three shield tail brushes are circularly welded at the tail of the shield machine, namely shield tail brush Ⅰ1-6, shield tail brush Ⅱ1-8, shield tail brush Brush III 1-10 forms two cavities, namely cavity I1-7 and cavity ...

AI Technical Summary

Problems solved by technology

[0005] At present, there are many manufacturers producing shield tail brushes in China, but there is no equipment in the industry to test the performance of shield tail brushes. When testing the wear-resistant and elastic equipment that determines the sealing performance of the shield tail brush, it is only based on intuition, and it is inevitable to purchase inferior products, which will bury safety hazards for construction and production.
