Hydraulic breaking hammer with protective device
The invention relates to the related field of breaking hammers, in particular to a hydraulic breaking hammer with a protection device. The hydraulic breaking hammer comprises a rear nitrogen chamber, a cylinder body, a lower shell assembly and a drill rod, a gap is reserved between a sealing frame and the inner cavity wall of the cylinder body, and the thickness of a damping block is larger than that of the gap, so that the influence of vibration of a piston rod on the cylinder body can be reduced; a damping device is arranged, a damping spring is connected between a mounting plate and a sliding block in a sleeving mode on the periphery of a telescopic rod in the damping device, a fixing block is arranged in the middle of the inner cavity wall of a mounting cavity, a linkage rod is connected between the fixing block and the sliding block, and a sliding rail is arranged at the position, corresponding to the sliding block, between a connecting plate and the inner cavity wall of the mounting cavity; the sliding block is in embedded sliding connection with the sliding rail, a plurality of reset springs are evenly arranged at the bottom of an inner cavity of the sliding block, meanwhile, a buffering air cushion is arranged on the periphery of the buffering rubber block, and the situation of vibration strain of the cylinder body and the piston rod can be greatly reduced through stretching of the telescopic rod and deformation of the buffering rubber block and the buffering air cushion.
本发明涉及破碎锤相关领域，具体为一种具有防护装置的液压破碎锤，后氮室、缸体、下壳体总成和钎杆，本发明通过在密封架与缸体内腔壁之间留有缝隙，且减震块厚度大于缝隙的厚度，从而可以降低活塞杆振动对缸体的影响；通过设置减震装置，且减震装置内伸缩杆外围于安装板与滑动块之间套接有减震弹簧，安装腔内腔壁中间设置有固定块，固定块与滑动块之间连接有联动杆，又连接板与安装腔内腔壁之间于滑动块对应处设置有滑轨，滑动块与滑轨相嵌合滑动连接，滑动块内腔底部均匀设置有若干个复位弹簧，同时缓冲橡胶块外围设置有缓冲气垫，则通过伸缩杆的伸缩、缓冲橡胶块和缓冲气垫的形变，可以极大减少缸体与活塞杆震动拉伤的情况。
