Shield tail brush wire pressing and bristle combining device of shield tunneling machine

Abstract

The invention belongs to the technical field of shield tail brush production and manufacturing equipment, and provides a shield tail brush wire pressing and bristle combining device of a shield tunneling machine which comprises an upper machine body and a lower machine body, the upper machine body is provided with a main oil cylinder, the movable end of the main oil cylinder faces downwards and is provided with a pressing plate, the pressing plate is vertically arranged, and a plurality of clamping notches used for clamping steel wire bundles are formed in the bottom of the pressing plate; two wire clamping devices which are symmetrically distributed relative to the pressing plate are arranged below the machine body, the wire clamping devices are arranged on the wire feeding mechanism, a lower mold piece is arranged under the pressing plate and comprises a profiled groove matched with the bottom of the pressing plate, side pressing plates are arranged on the two sides of the lower mold piece, and plate grooves used for containing shield tail brush clamping plates are formed in the side pressing plates. A sliding block and sliding rail mechanism is arranged below the side pressing plate, and a constant-pressure oil cylinder connected with the side pressing plate is arranged on one side of the side pressing plate. The device is reasonable in design, simple in structure, good in maneuvering performance, high in production efficiency, beneficial to reduction of production cost and suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of shield tail brush production and manufacturing equipment, and relates to a shield tail brush pressing and wool-pressing device of a shield tunneling machine. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a special construction machine for tunnel boring. The shield tail brush is used to inject a certain amount of grease filler into the gap formed by the fluffy steel wire after bending to play a good sealing role between the shield and the segment, preventing groundwater, outer soil, lining back grouting, etc. from flowing into the tunnel , to ensure the safety of tunnel excavation and the smooth progress of the project. The shield tail seal of the shield machine is composed of 3 shield tail brushes, forming two grease compartments, namely the front compartment and the rear compartment, the front two are long shield tail brushes, and the third is short shield...

AI Technical Summary

Problems solved by technology

Moreover, the tail brush of the large shield machine bears a lot of pressure and wears seriously during work, and consumes a lot

In addition, the shield tail brush is a special accessory of the shield machine, and there are few manufacturers, so the market has been out of stock

Although the market demand for shield tail brushes is large, its processing and manufacturing have not yet been automated, so the production capacity is low, resulting in high costs

[0003] At present, the steel wire bundles of the shield tail brush are formed by bending the steel wires and fluffing them. Each steel wire bundle has as many as 4,500 steel wires. The traditional artificial steel wire bundles need to be laid first and pressed at least three times. The preparation process is cumbersome and the processing The process is complex, which leads to low production efficiency. How to quickly close and press thousands of steel wires into bundles is the decisive process stage that determines the production rate of tail brushes, which is also the main reason for the high cost of shield tail brushes.
