Problems solved by technology

The traditional braking device is installed between the motor and the reducer, and is composed of a brake cylinder, a rocker lever, a brake hub, a brake band, a bracket, and a spring. Precise control and adjustment, long braking time, difficult maintenance, unable to meet the needs of safety, adjustable control and accurate parking, and excessive heat generated during braking will accelerate the aging of the lubricating oil of the reducer, affecting the stable operation of the transmission system

Abstract

The invention provides a hollow shaft motor reverse transmission braking device for a hard rock heading machine. The braking device comprises a transmission gear set, a planetary reducer, a hollow shaft motor, a concentric shaft, a hydraulic safety coupler and a braking mechanism. The braking mechanism is arranged on the hydraulic safety coupler. The hydraulic safety coupler is connected with the motor hollow shaft of the hollow shaft motor. The concentric shaft is arranged in the motor hollow shaft, one end of the concentric shaft is connected with the hydraulic safety coupler, and the other end of the concentric shaft penetrates through the motor hollow shaft and is connected with the input end of the planetary reducer. The output end of the planetary reducer is connected with the transmission gear set. Reverse transmission and reverse braking are achieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery for hard rock roadheaders, in particular to a hollow shaft motor reverse transmission brake device for hard rock roadheaders. Background technique [0002] In the construction process of hard rock roadheaders, it is often necessary to accurately position at a certain station and slowly rotate the cutter head, such as tool change, maintenance, maintenance and overhaul. Usually the cutter head is in a state of static balance, but if one or more When the cutter head is removed, the cutterhead will lose its balance and rotate itself, which poses a greater safety threat to the operator. Due to the urgent need for safety, adjustable control and accurate parking, the drive device is required to fully guarantee the safety of maintenance personnel. It has fast, accurate and reliable braking function. The traditional braking device is installed between the motor and the reducer, and is compos...
