The invention relates to the field of hydraulic hoists, and discloses a hydraulic hoist for hoisting, dismounting and mounting coal mine equipment, which comprises a hydraulic hoist body and a hydraulic motor for driving the hydraulic hoist body, and the hydraulic motor is connected with a hydraulic buffer to protect the hydraulic motor at the moment of unloading of the hydraulic hoist body. The hydraulic buffer comprises a shell, a first elastic pressure relief mechanism, a top impact mechanism and a second elastic pressure relief mechanism, and has the beneficial effects that the whole pressure relief process can be rapidly completed, most hydraulic oil can be contained through a first channel and a second channel, most impact pressure in a system is absorbed, and the service life of the system is prolonged. And the influence of hydraulic impact on the hydraulic motor and the whole hydraulic system is prevented.

    本发明涉及液压葫芦领域,公开了一种煤矿设备吊运拆装用液压葫芦,包括液压葫芦本体以及用于驱动液压葫芦本体的液压马达,所述液压马达连接有液压缓冲器以在所述液压葫芦本体卸货的瞬间对所述液压马达起保护作用,所述液压缓冲器包括壳体、第一弹性泄压机构、顶冲机构和第二弹性泄压机构,有益效果:整个泄压过程可以迅速完成,利用第一通道和第二通道可以收容大部分液压油,吸收系统中的大部分冲击压力,防止液压冲击会对液压马达及整个液压系统造成影响。
