Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as Figures 1 to 8 As shown, an electromagnetic impact rock-breaking drilling device includes a mounting plate 1, one side of the mounting plate 1 is provided with a plurality of drill mechanisms 2, and the other side is fixedly connected to the end of the shield body 3, and the drill mechanism 2 It includes an installation cylinder 2.1 fixedly arranged in the installation disk 1, and a drill bit 2.2 which can move back and forth and rotate by itself is arranged in the installation cylinder 2.1. Preferably, the drill bit 2.2 in this embodiment is a conical structure with a plurality of protrusions distributed on its surface, which can increase the contact area of ​​the drill bit 2.2 to the rock mass and improve the rock breaking efficiency; in addition, the shield body 3 is a cylindrical structure , to protect the interna...

Abstract

The invention discloses an electromagnetic impulsive rock breaking and drilling device and an application method. The device comprises a mounting disc. A plurality of drill bit mechanisms are arrangedon one side of the mounting disc, the other side of the mounting disc is fixedly connected to the end part of a shield, and each drill bit mechanism comprises a mounting barrel fixedly arranged in the mounting disc, and a self-rotating drill bit capable of moving front and back is arranged in the mounting barrel. In addition, the invention discloses the application method corresponding to the device. The device solves the problem that an existing rock breaking technique is insufficient in safety, pollutes the environment and is low in efficiency, and meanwhile, achieves impulsive rock breaking and rotary drilling functions.

Description

technical field [0001] The invention relates to the technical field of rock breaking, in particular to an electromagnetic impact rock breaking drilling device and a use method. Background technique [0002] In recent years, with the rapid development of cities, industries, and transportation construction, a large number of projects require excavation and crushing of rock mass. At the same time, the requirements for rock mass crushing are getting higher and higher, such as controlling blasting vibration, reducing noise and environmental pollution, etc. has become an urgent problem to be solved. Currently, rock breaking methods mainly include explosive crushing, static crushing and shield technology. Explosive blasting is fast, easy to operate, and convenient, but poor in safety. Blasting is used to break rocks. During the explosion, vibration, noise, environmental pollution, and impact on the entire rock structure make its stability lower and prone to geological problems. S...
