Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] see Figure 1-3 , the present invention provides a technical solution: a mining hydraulic support column with an anti-crushing device, including a base 1, a fixed plate 2, a limit seat 3 and a top seat 4, the upper surface of the base 1 is close to the edge A fixed cover 11 is fixedly connected by bolts, and the middle part of the inner wall of the fixed cover 11 is rotatably connected with a support plate 12. The support plate 12 can be effectively rot...

The invention discloses a mining hydraulic support column with an anti-crushing device, which includes a base, a fixed plate, a limit seat and a top seat. The upper surface of the base is connected to a fixed cover through bolts near the edge. A support plate is rotatably connected to the middle part of the inner wall of the fixed cover; the present invention is convenient for users to install and fix by providing a base and a top seat. At the same time, the fixed cover and the support plate enable the fixed plate to telescope through the first hydraulic column while also being able to adapt to the needs. Deflect, and through the second hydraulic column provided, the limit seat and the fixed plate can be effectively fixed, and at the same time, movable buffering can be achieved, so that the fixed plate and the limit seat can be movable and retracted in an emergency, thereby achieving the top The seat and the base are positioned and supported by the limiting seat and the fixing plate, and can also effectively prevent crushing, thus effectively making up for the deficiencies in the prior art.
Description
technical field [0001] The invention relates to the technical field of support columns, in particular to a mining hydraulic support column with an anti-crushing device. Background technique [0002] Due to the complex occurrence conditions of metal deposits, the properties of ores and surrounding rocks are changing, and with the development of science and technology, new equipment and materials are constantly emerging, new processes are becoming more and more perfect, and some old ones are low in efficiency and labor-intensive. The existing mining methods have been eliminated accordingly, and in practice, various mining methods suitable for the occurrence conditions of specific ore blocks have been innovated, and in all kinds of mining methods, hydraulic support columns are needed to support mining operations. In order to ensure the normal progress of mining, there are still some deficiencies in the actual application of hydraulic support columns for mining in the prior art,...
