Problems solved by technology

Due to the complex geological conditions of hard rock, hard rock roadheaders often encounter the situation that the cutter head is stuck due to insufficient torque to escape the trap. The traditional hard rock roadheader can no longer meet the current construction needs, especially the main drive structure urgently needs to be improved.

Abstract

The invention provides a hydraulic gear-shifting double-speed hard rock heading machine main drive planetary gear box which is installed between a heading machine main motor and a main drive box, the reduction ratio in a high-speed mode is 30, the reduction ratio in a low-speed mode is 55, mode switching can be directly conducted through control of a hydraulic clutch, and the hydraulic gear-shifting double-speed hard rock heading machine main drive planetary gear box has the advantage of being convenient to switch. And in a low-speed mode, the escape torque of the equipment can be increased by 1.8 times. Practical engineering verifies that the double-speed differential planetary gearbox is mounted on the hard rock heading machine, so that the escape capability of the open type hard rock heading machine under the geological condition of weak and broken surrounding rock can be greatly improved.

Description

technical field [0001] The invention relates to a planetary gear box structure, in particular to a main drive planetary gear box of a hydraulically shifted double-speed hard rock tunneling machine. Background technique [0002] Tunnel boring machine is a kind of tunnel construction machine that uses rotary cutters to excavate, simultaneously breaks the surrounding rock in the hole and excavates, and forms the entire tunnel section. Among them, the one used for soft ground is called shield machine, and the one used for rocky ground is called Hard Rock Tunneling Machines. The hard rock roadheader can complete the parallel and continuous operation of the construction procedures such as tunneling, support, and slag discharge. It is a factory-like assembly line tunnel construction equipment integrated with mechanical, electrical, hydraulic, optical, and gas systems. It has fast tunneling speed, environmental protection, and comprehensive With the advantages of high efficiency, i...
