Description

Adjustable brush head punching device

Technical Field

The utility model relates to a tunnel construction equipment especially indicates an adjustable flushing head device.

Background

At present, tunnels such as urban underground highways, express ways, highway-railway dual-purpose tunnels and the like are large-diameter tunnels, and the construction by adopting a large-diameter slurry shield becomes a development trend of the construction of a new urban large-diameter tunnel. The slurry shield is provided with a crusher at the front end of the slurry discharge hole so as to be capable of tunneling in rocks, pebbles or fractured strata. The slurry shield is composed of a slurry cabin and an air cushion cabin, a crusher is arranged at the bottom of the air cushion cabin, the crusher is mainly a jaw crusher, large-particle-size rocks entering the air cushion cabin are crushed in time, and then enter a slurry discharge pipe through screening of a grid so as to be discharged out of a hole.

Considering the possibility of blockage and blockage at the slurry outlet at the bottom of the shield body, a bottom flushing pipeline is arranged at present and is used for flushing sludge accumulated at the slurry outlet. Due to the limitation of space and the complexity of structural components, dead angles exist in the scouring, the scouring is not in place, and the effect is not ideal. If the erosion is not timely, the slurry discharge system cannot work, excavated dregs and rocks cannot be discharged out of the hole, and the construction difficulty, efficiency and cost are greatly increased.

The flushing pipe is welded with the left flange, and the right flange is welded with the flushing head.

The left flange on be equipped with the articulated seat in a left side, be equipped with the articulated seat in the right side on the flange in the right side, the articulated seat in a left side is articulated with the articulated seat in the right side.

The left hinged seat is hinged with the right hinged seat through a bolt.

The flexible pipe is an expansion joint.

The adjusting device is an oil cylinder.

The outlet of the flushing brush head is flat.

The scouring head component is positioned at the slurry outlet at the bottom of the shield body.

The realized functions or purposes are as follows: an adjustable punch head device is provided; the washing range is convenient to expand, the washing dead angle is reduced, and the washing effect is improved.

Has the advantages that: the adjustable certain angle of brush head, and wash the wide range, wash and do not have the dead angle, improve and wash the effect, simple structure is reliable, convenient operation.
