A free-section hard rock excavation equipment

Abstract

The invention discloses a free section hard rock excavation equipment, which solves the problem of low excavation efficiency of a super large section shaft in the prior art. The invention includes a mobile car body, the front end of the mobile car body is hinged with a connecting frame, the connecting frame is provided with a drum-type cutter head, the connecting frame is connected with the mobile car body through a telescopic drive mechanism, and the drum-type cutter head is connected to the mobile car body. The slag conveying mechanism on the car body is corresponding. Preferably, the mobile vehicle body is provided with a cab and a base, the base is located at the front of the cab, the connecting frame is hinged on the base, and the bottom of the mobile vehicle body is provided with a crawler walking mechanism. The invention realizes the flexible and high-efficiency excavation of the hard rock section through the excavation of the drum type cutterhead and the movement of the crawler, is suitable for the excavation of shafts with super large sections and free sections, and reduces equipment investment. A certain number of slag outlets are set along the circumference of the drum-type cutter head, through which the rock slag is transported to the rock slag conveying mechanism and discharged to the rear of the equipment to achieve efficient slag discharge.

Description

Technical field [0001] The present invention relates to the field of shaft excavation technology, in particular refers to a free section hard rock excavation equipment. Background [0002] With the continuous development of urban space, the construction of urban underground projects such as underground parking lots, underground oil storage depots, underground pile foundations and other super-large diameter shaft projects is becoming increasingly demanding. Traditional vertical shafts generally use manual semi-mechanized excavation methods, or use conventional drilling equipment for construction, but in the excavation of large diameter shafts, the disadvantages of manual semi-mechanized excavation methods in safety and efficiency are becoming more and more prominent, while conventional drilling equipment is not suitable for ultra-large section excavation. Large diameter shafts generally have shallow excavation depth, short project construction period, and use customized hard rock ...
