An anti-shock full-section adjustable self-balancing mine support device

Abstract

The invention discloses an anti-impact, full-section, adjustable and self-balancing mine support device. The anti-impact, full-section, adjustable and self-balancing mine support device comprises an X-axial component, Y-axial components and hydraulic shock-insulation force transmitting elastic components, wherein the X-axial component and the Y-axial components are used for bearing action force, and the hydraulic shock-insulation force transmitting elastic components are arranged between the X-axial component and the Y-axial components; the Y-axial components are arranged in a left-right symmetry mode along the X-axial component, and connected with the X-axial component through the hydraulic shock-insulation force transmitting elastic components to form a support structure; and when the X-axial component bears the action force, the action force is applied to the Y-axial components through the hydraulic shock-insulation force transmitting elastic components, and when the Y-axial components bear the action force, the action force is applied to the X-axial component through the hydraulic shock-insulation force transmitting elastic components. Through assembly of the X-axial component,the Y-axial components and the hydraulic shock-insulation force transmitting elastic components arranged between the X-axial component and the Y-axial components, the integrated support structure isconstituted, and thus the load generated by deformation and extrusion of external surrounding rock and borne by the support device can be reduced and homogenized.

Description

technical field [0001] The invention relates to the technical field of coal mine underground or tunnel support, in particular to an anti-shock full-section adjustable self-balancing mine support device. Background technique [0002] At present, metal support technology has been widely used in tunnel support of mine roadways, railways and various underground projects at home and abroad. With the maturation of roadway metal support technology, the application in mine roadway or tunnel support is becoming more and more important. There are many types of traditional support devices. Through the application of different types of support devices in engineering, it is found that the existing support devices have poor overall structural stability and uneven force during the support process. Due to the deviatoric stress of the surrounding rock, it is easy to cause damage under the extrusion of the surrounding rock deformation, and it is difficult to apply a relatively uniform suppor...

Problems solved by technology

[0005] 1. It is difficult to apply a relatively uniform support force to the surrounding rock during the support process, and its own structural adjustment ability is poor. The deformation of the roadway surrounding rock has a greater impact on the support structure, and the support structure is easily deformed due to excessive local load. The overall support structure is unstable and damaged or fails;

[0006] 2. In the prior art, metal bracket support is a passive support method, and it is difficult to obtain ideal support effects, especially for impact mine roadways. During the roadway support process, under the influence of strong mine pressure, it is affected by impact dynamic Due to the impact of load, it often occurs that the support device cannot adapt to the severe deformation of the surrounding rock well, and is easily subjected to local deformation and extrusion loads of the surrounding rock, resulting in excessive local stress on the structure, which leads to the overall stability of the support being easily reduced, and deformation and failure occur. Can not give full play to its supporting performance;

[0007] On-site construction must adapt the support structure to the deformation of the surrounding rock, strengthen the coupling relationship between the support structure and the surrounding rock, and give full play to the overall supporting force of the support structure while limiting the deformation of the surrounding rock, otherwise it is not conducive to the bearing structure of the surrounding rock The formation and adjustment of the surrounding rock will easily lead to a decrease in the self-supporting capacity of the surrounding rock, resulting in excessive convergence and deformation of the roadway. Therefore, we propose an anti-shock full-section adjustable self-balancing mine support device to solve the above problems
