Jointed rock mass dynamic load test device

Abstract

The invention discloses a jointed rock mass dynamic load test device which comprises a supporting frame, a pressure sensing device is arranged at the bottom of the middle of the supporting frame, a lifting frame is connected to the supporting frame in an inserted mode, a height adjusting device is arranged on the back of the lifting frame, a U-shaped frame is installed on one side of the upper end of the lifting frame, a rotating block is rotationally installed on the U-shaped frame, and a telescopic rod is installed on the rotating block. The jointed rock mass dynamic load test device has the advantages that the height adjusting device is arranged on the back of the lifting frame, so that in the using process, on the premise that a first threaded bolt and a second threaded bolt are unscrewed, the height adjusting device can adjust the height of the lifting frame, and the height adjusting device can adjust the height of the lifting frame to be larger than the height of the lifting frame; the threaded rod is rotated through the rotating ring, synchronous change of the height of the lifting frame and the height of the telescopic rod can be achieved, so that the test device can meet different test condition requirements, experimental data are more scientific and reasonable, and meanwhile operation is easy and convenient.

Description

technical field [0001] The invention relates to the field of rock mass testing devices, in particular to a joint rock mass dynamic load testing device. Background technique [0002] In order to analyze, measure and calculate the properties of the jointed rock mass, it is necessary to carry out a dynamic load test on the jointed rock mass. However, in the current test process, due to the influence of the test device, the jointed rock mass can generally only be rotated to a certain level before allowing The falling impact pressure sensing device is difficult to achieve when it is necessary to impact the pressure sensing device on the jointed rock mass at different heights, and the equipment needs to be replaced, which is rather troublesome. [0003] To this end, the present invention proposes a jointed rock mass dynamic load test device to solve the above problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a jointed rock mass dynam...
