when the external upper component I3 and the external upper component II 4 bear acting force in the horizontal direction, the external upper component I3 and the external upper component II 4 move towards the cavity, the middle parts of the external upper component I3 and the external upper component II 4 apply the acting force to the hydraulic shock-insulation force-transmission elastic component 6 in the cavity, and the hydraulic shock-insulation force-transmission elastic components 6 between the rib plate I2-2 and the rib plate II 3-2 and between the rib plate III 5-3 and the rib plate IV 4-3 are also contracted;
certainly, concave notches, mounting round holes I2-3, mounting round holes II 3-3, mounting round holes III 3-5, mounting round holes IV 4-2, mounting round holes V4-4 and mounting round holes VI 4-5 are processed in the rib plates I2-2, the rib plates II 3-2, the rib plates III 5-3 and the rib plates VI 4-5 in advance, the hydraulic shock-insulation force-transmission elastic members 6 and the rib plates are fastened through mounting pins 7, the mounting and the connection are convenient, and the mounting and the recycling of the supporting device are facilitated;
in the above embodiment, since the supporting device is a whole, the structures interact with each other, so as to improve the stress state of the support, apply a relatively uniform supporting resistance to the surrounding rock, and the acting force generated in any direction (for example, the load generated by deformation and extrusion of the surrounding rock) can be transmitted among the structures, so that the self structure can be used for alleviating and homogenizing the deformation load of the external surrounding rock borne by the supporting device, so as to improve and optimize the stress state of the supporting device, facilitate the stress of the supporting device to tend to be balanced, enhance the bearing capacity of the supporting device, facilitate the common stress of each component, coordinate with the deformation of the surrounding rock, adapt to the deformation of the surrounding rock, and stabilize the surrounding rock;
schematic illustration: in the above embodiment, when the upper member I3 and the upper member II 4 receive a vertical force, the hydraulic shock-insulation force-transmission elastic component 6 between the ribbed plate V3-4 and the ribbed plate VI 4-5 contracts, because the action of the forces are mutual, the hydraulic shock-insulation force-transmission elastic component 6 also reversely applies the acting force to the external upper component I3 and the external upper component II 4, the acting forces are mutually offset, meanwhile, the support device can be effectively prevented from being integrally damaged and failed due to overlarge dynamic load caused by impact between the outer wall component I3 and the outer wall component II 4 through shrinkage deformation, and in general, the hydraulic shock-insulation force-transmission elastic component 6 can deform on one hand, adapts to surrounding rock deformation and transmits load, and on the other hand can bear larger load action, has certain supporting capacity and ensures the strength of a support structure;
when the arch-shaped part I2 bears the acting force in the vertical direction, the acting force is applied to the hydraulic shock-insulation force-transmission elastic component 6 in the cavity at two end parts, and the supporting device is a whole, so that the load generated by the acting force is transmitted to the side part and the bottom part of the roadway through the supporting device, the convergence deformation of the side part and the bottom part of the roadway is limited by the acting force in the vertical direction (the top surrounding rock deformation extrusion load), the supporting resistance loss is reduced, the interaction and the joint bearing of all parts in the surrounding rock supporting process are ensured, the bearing capacity of the supporting device is improved, and the surrounding rock is favorably stabilized;
when the external upper component I3 bears the acting force in the horizontal direction, the upper end of the external upper component I3 can move along the upper end face of the arch-shaped part I2, and similarly, when the external upper component II 4 bears the acting force in the horizontal direction, the lower end of the external upper component II 4 can move along the lower end face of the arch-shaped part II 5 and can move mutually to form contraction when the acting force is applied, in short, the upper and lower directions can move to transfer load so as to support the top and the bottom of the roadway;
of course, the supporting structure in this embodiment may apply an acting force to the supporting structure in any direction except for the X-axis direction and the Y-axis direction, in other words, the embodiment gives the X-axis direction and the Y-axis direction stress of the supporting structure, but the supporting structure is not limited to the use scenario in which the X-axis direction and the Y-axis direction are stressed;
in conclusion, no matter the acting force in any direction is received, the hydraulic shock-insulation force-transmission elastic component 6 is matched with the retractility of the supporting structure to ensure the supporting of all sections, the hydraulic shock-insulation force-transmission elastic component 6 can offset the deformation load of surrounding rocks appearing under strong mine pressure and can contract and deform to effectively avoid the overall damage and failure of the supporting device caused by overlarge dynamic load due to impact, the coordination capability of the structures of all components of the supporting device and the deformation of the surrounding rocks is enhanced, and the supporting performance of the supporting device is improved;
it should be noted that the acting force in this embodiment at least includes an impact dynamic load and a deformation compression load, and of course, the acting force may also include an earthquake acting force, a blasting acting force, and the like;
in consideration of the problem of load transfer, the edges of the external upper component I3 and the external upper component II 4 can be widened, so that the load can be easily transferred while the flexibility is ensured;
in view of the problem of contractibility, the arch ii 5 is initially broken in the middle, and as shown in fig. 2, the arch ii 5 can be overlapped and connected together by the clip 1, as shown in fig. 1, so that when the support device is contracted, the left and right sides of the arch ii 5 can move toward each other to facilitate the contraction of the support device.
