Gravity type breaking hammer and automatic control method thereof
The invention discloses a gravity-type breaking hammer and a control method thereof. The gravity-type breaking hammer comprises a barrel, a driving device and a driving device, a drill rod; a hammer block; the piston cylinder comprises a cylinder barrel and a piston rod fixedly connected with the hammer block; a drive pump; the fluid pipeline is connected between the driving pump and the piston cylinder; the control valve assembly is arranged on the fluid pipeline; the first detection device is used for detecting whether the hammer block reaches a first position on the barrel or not in the upward moving process of the hammer block; the control device is in signal connection with the control valve assembly and the first detection device, comprises a timing device, and is configured as follows: when the first detection device detects that the hammer block reaches the first position in the upward moving process of the hammer block, the timing device is started; the control device controls the control valve assembly to cut off the communication between the driving pump and the piston cylinder after a first time so as to enable the hammer block to continuously move upwards under the inertia effect, and the control device controls the control valve assembly to act so as to enable the hammer block to start to move downwards after a second time after the communication between the driving pump and the piston cylinder is cut off.
本发明公开一种重力式破碎锤及其控制方法，重力式破碎锤包括：筒体；钎杆；锤块；活塞缸，包括缸筒和与锤块固定连接的活塞杆；驱动泵；流体管路，连接在驱动泵和活塞缸之间；控制阀组件，设在流体管路上；第一检测装置，用于在锤块向上移动的过程中检测锤块是否到达筒体上的第一位置；控制装置，与控制阀组件和第一检测装置信号连接，包括计时装置，控制装置被配置为：在锤块向上移动过程中第一检测装置检测到锤块到达第一位置时，控制装置控制控制阀组件经过第一时间后切断驱动泵与活塞缸之间的连通以使锤块在惯性作用下继续向上移动，且在切断驱动泵与活塞缸之间的连通后再经过第二时间后，控制装置控制控制阀组件动作以使锤块开始向下移动。
