Energy storage type drop hammer quick-release impact device

Abstract

The invention relates to an energy storage type drop hammer quick-release impact device, which belongs to the technical field of mining disaster prevention and control, and comprises a hydraulic cylinder, a drop hammer release device, a pull rod, a sleeve, a spring and a drop hammer. The drop hammer release device comprises a locating sleeve with a locating hole in the center; grooves are formed on the bottom part of the locating sleeve; glands are arranged on the bottom parts of the grooves; the inner ends of the grooves communicate with the locating hole; clamping jaws are arranged in the grooves; reset springs are arranged in the grooves between the clamping jaws and the locating sleeve; locating clamp slots are formed in the middle parts of the clamping jaws; the lower part of a locating body is arranged in the locating clamp slots; the outer side faces of the lower part of the locating body are provided with inclined planes; the drop hammer is arranged in the sleeve; the upper end of the pull rod penetrates through the through hole of the sleeve so as to be arranged in the locating hole of the drop hammer release device; clamping slots are formed on the upper end of the pull rod; the inner ends of the clamping jaws are arranged in the clamping slots; the lower end of the pull rod is fixedly connected with the drop hammer; the spring is arranged in the sleeve above the drop hammer; a piston rod of the hydraulic cylinder is fixedly connected with the locating sleeve of the drop hammer release device.

Description

technical field [0001] The invention belongs to the technical field of mine disaster prevention, in particular to an energy-storage drop hammer quick-release impact device, which is mainly used for studying the dynamic mechanical properties of rocks. Background technique [0002] Currently used drop weight impact test devices all need to raise the drop weight to a certain height to obtain the required impact energy. In order to obtain impact energies of different magnitudes, it is necessary to raise the drop hammer to a very high height, or to increase the mass of the drop hammer. Therefore, the current drop weight impact test device takes up a lot of space, and the operation is complicated, and each time the impact is completed, it is necessary to raise the drop weight to a specified height again, or increase or decrease the quality of the drop weight, which takes a long time and has low work efficiency. Contents of the invention [0003] Aiming at the problems existing ...
