Abstract

The invention belongs to the field of digging and relates to a method for buffering a reciprocating impact tunneling counter-acting force and a buffering heading machine adopting the method. The buffering heading machine comprises a machine body, a travel unit, a reciprocating impact unit, and a buffering unit. The buffering unit comprises a dynamic buffering device or a structure buffering guiding device. The reciprocating impact unit comprises an impact driving device, a fixing support and a buffering support. The dynamic buffering device comprises a rotary dynamic buffering device. The rotary dynamic buffering device comprises a slide stroke splined hub buffering device or a belt buffering device. The structure buffering guiding device is arranged between the reciprocating impact unit and the machine body or between the fixing support and the buffering support. The structure buffering guiding device can guide a buffering direction of the dynamic buffering device and / or a structure buffering device. The buffering unit can buffer and resolve a counter-acting force on the reciprocating impact unit. The reciprocating impact unit is arranged at the machine body. The travel unit drives the machine body to travel.

Description

technical field [0001] The invention relates to tunneling equipment, in particular to a method for buffering the reaction force of reciprocating impact tunneling and a buffer tunneling machine implementing the method. Background technique [0002] The currently widely used mining excavation equipment is the cantilever type roadheader. Its working principle is drilling type; at present, numerous percussion type roadheaders have been developed in succession in this field. Both excavation methods have relatively large reaction force on the fuselage, which is easy to cause damage to the fuselage during the excavation process. [0003] The patent No. is 200620137402.7, and the name is called "energy-saving impact mining machine" and discloses a mining machine with an impact arm and an impact head. The output shaft of the motor is connected with the variable speed transmission mechanism. When the motor is working, the variable speed transmission mechanism converts the rotational...
