Pressure detection type impact-resistant energy absorption device suitable for advanced hydraulic support

Abstract

The invention provides a pressure detection type impact-resistant energy absorption device suitable for an advanced hydraulic support. The pressure detection type impact-resistant energy absorption device comprises a bottom supporting plate, a middle impact-resistant structure assembly, a top supporting plate and deformation pressure sensors, wherein the bottom supporting plate, the middle impact-resistant structure assembly and the top supporting plate are sequentially arranged from bottom to top; the four deformation pressure sensors are evenly distributed on the upper surface of the top supporting plate and located at the four corners of the top supporting plate. Four arc-shaped half-moon buffer plates are evenly distributed on the peripheral side of the middle impact-resistant structure assembly; the middle impact-resistant structure assembly comprises a plurality of hollow cylinders and is of a multi-stage layered structure, the layered structure is divided into two types, and the two types of layered structures are alternately arranged in the height direction; the hollow cylinders in the first type of layered structure are perpendicularly staggered and are horizontally arranged; the hollow cylinders in the second type of layered structure are perpendicularly staggered and are perpendicularly and horizontally arranged alternately; and displacement sensors are arranged in the middles of the side vertical faces of the four edges of the bottom supporting plate and the top supporting plate and correspond to one another in position in a one-to-one manner.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and in particular relates to a pressure detection type anti-impact energy-absorbing device suitable for an advanced hydraulic support. Background technique [0002] With the widespread implementation of intelligent mining technology in coal mines, the output and efficiency of coal mining have been greatly improved, but there are still some problems in the process of coal mining, and these problems become more and more obvious as the output increases. For example, during the application process, the advanced hydraulic support will be subjected to the alternating action of roof rock movement and impact pressure. The excessive impact force will easily lead to accelerated aging of the advanced hydraulic support, shortened service life, and even cause safety accidents. In order to avoid such problems, some simple anti-shock devices are usually fixedly installed in some places with relatively ...
