Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0030] In the following specific embodiments, the thermal insulation composite anchoring component is applied to deep mines. Due to the geothermal gradient effect, the influence of geothermal heat on the mine becomes more obvious with increasing mine depth, thus forming a high-temperature mine. If the metal anchoring system is directly applied to such a high-temperature mine, the geothermal heat will be directly conducted to the mine interior through the metal anchoring system, leading to a deterioration of the working environment inside the mine. Therefore, the anchoring component needs to be thermally insulated. The structure and function of the thermal insulation composite anchoring component applied to high-temperature mines are illustrated below with reference to various embodiments.

[0031] In some embodiments, such as Figure 1 As shown, the thermal insulation composite anchoring assembly 10 includes: an anchor mesh 100 and anchor bolts 200. The anchor mesh 100 is used to cover the inner wall of the mine, providing support for the inner wall. The anchor mesh 100 can also catch debris or parts falling into the mine, thereby improving the safety of workers in the mine. A portion of the anchor bolt 200 is inserted into the wall of the high-temperature mine, and the other portion of the anchor bolt 200 extends out of the wall and connects to the anchor mesh 100. It can be understood that the anchor bolt 200 can reliably fix the anchor mesh 100 to the mine wall. At the same time, the anchor mesh 100 can connect multiple anchor bolts 200 together, thereby connecting multiple anchor bolts 200 to form an anchor bolt reinforcement system to reinforce the mine. Optionally, multiple anchor bolts 200 can also be connected by metal wires. The metal wires can apply a tension force to the multiple anchor bolts 200 to bring them closer together, thereby further reinforcing the mine.

[0032] The outer surface of the part of the anchor rod 200 extending out of the mine wall is provided with a first heat insulation structure 210. It should be noted that, in order to improve the reliability of reinforcing the mine, the part of the anchor rod 200 extending into the mine wall needs to be made of a metal material. However, the metal material generally has a high thermal conductivity, and the geothermal heat of the high-temperature mine can be quickly conducted to the mine through the anchor rod 200, so that the temperature in the mine quickly rises. By arranging the first heat insulation structure 210 on the outer surface of the part of the anchor rod 200 extending out of the mine wall, the heat conducted into the mine through the anchor rod 200 can be reduced, so that the rising speed of the temperature in the mine is slowed down, and thus the working environment in the mine can be improved while reliably reinforcing the mine.

[0033] It should be noted that the first heat insulation structure 210 can be formed in any form. For example, the anchor rod 200 can be a two-segment structure, the part of the anchor rod 200 extending into the mine wall is made of metal, and the part of the anchor rod 200 extending out of the mine wall is made of a heat insulation material, so that the first heat insulation structure 210 is formed by the heat insulation material. For example, the anchor rod 200 is made of a metal material as a whole, and a heat insulation member is sleeved on the outside of the part of the anchor rod 200 extending out of the mine wall, so that the first heat insulation structure 210 is formed.

[0034] The utility model discloses an application in high temperature mine's heat insulation composite anchor assembly, this heat insulation composite anchor assembly includes: the surface of the anchor net for covering high temperature mine mine wall, and with anchor net connection anchor rod, wherein, the part of anchor rod extends into high temperature mine mine wall, and the anchor rod reinforcing system is formed to the multiple anchor rod through anchor net connection, and this anchor rod reinforcing system can reliably reinforce the mine, and simultaneously, the outer surface of the part of anchor rod extending out of mine wall is provided with first heat insulation structure, in order to improve the reliability of reinforcing the mine, the part of anchor rod extending into mine wall needs to be made of metal material, but metal material generally has high thermal conductivity, and the geothermal heat of high temperature mine can be quickly conducted to the temperature in the mine that rises quickly through anchor rod, through the outer surface of the part of anchor rod extending out of mine wall is provided first heat insulation structure, can reduce the heat that passes through anchor rod and is conducted into the mine, so that the rising speed of the temperature in the mine is slowed down, and thus can reliably reinforce the mine while, improve the working environment in the mine.

[0035] In some embodiments, as shown in Figure 2 The anchor rod 200 includes a fixed segment 220 and a heat insulation segment 230. The fixed segment 220 is used to extend into the mine wall and is made of metal, so as to reliably fix the anchor rod 200 with the mine wall and realize reliable reinforcement of the mine. The heat insulation segment 230 is fixed to the end of the fixed segment 220 and extends out of the mine wall of the mine. The heat insulation segment 230 is used to be connected with the first heat insulation structure 210. Figure 1The anchor net 100 is connected in the anchor rod 200, and the heat insulation section 230 is made of heat insulation material, so that the first heat insulation structure 210 can be understood as follows: by making the anchor rod 200 into a sectional structure, using the fixing section 220 made of metal to form a reinforcing structure with greater structural strength, and using the heat insulation section 230 made of heat insulation material as a whole to form the first heat insulation structure 210, so that the first heat insulation structure 210 has greater thickness, and the heat insulation capacity of the anchor rod 200 is improved. Alternatively, the heat insulation section 230 is made of heat insulation plastic, which is injection molded from the end of the fixing section 220, so that the anchor rod 200 has sufficient overall structural strength while improving the heat insulation capacity of the heat insulation section 230 of the anchor rod 200.

[0036] In some embodiments, as shown in Figure 3 The anchor rod 200 is made of metal material as a whole, that is, the anchor rod 200 is an integral structure made of metal material, so that the anchor rod 200 has greater structural strength, and the first heat insulation structure 210 includes a heat insulation sleeve 240, which is sleeved outside the part of the anchor rod 200 that protrudes out of the well wall, that is, the first heat insulation structure 210 is formed by the heat insulation sleeve 240, so as to reduce the heat conduction capacity of the anchor rod 200 and reduce the heat conducted into the mine through the anchor rod 200, thereby improving the working environment in the mine. Alternatively, the heat insulation sleeve 240 is detachably connected with the anchor rod 200, and after the anchor rod 200 is inserted into the well wall, the heat insulation sleeve 240 is convenient to carry, so that the heat insulation sleeve 240 can be sleeved on the part of the anchor rod 200 that protrudes out of the well wall in the mine, thereby facilitating construction. Alternatively, the heat insulation sleeve 240 is made of silicone rubber, and the thickness of the silicone rubber is 2 mm, which is installed on the exposed part of the anchor rod and wrapped around the exposed part of the anchor rod to insulate the exposed part of the anchor rod through the silicone rubber layer, thereby reducing the heat transferred into the mine through the anchor rod, and the portable embedded design of the rubber heat insulation sleeve facilitates installation and improves construction efficiency.

[0037] In some embodiments, the outer surface of the part of the anchor rod 200 that protrudes out of the well wall is also coated with heat insulation paint, so as to further improve the heat insulation capacity of the part of the anchor rod 200 that protrudes out of the well wall, further reduce the heat transferred into the mine through the anchor rod 200, and optimize the working environment in the mine. Alternatively, the part of the anchor rod 200 that protrudes out of the mine is attached with an aerogel heat insulation coating, which is processed by spraying, and the spraying thickness is 0.5 mm. By preliminarily insulating this part of the anchor rod, the heat transferred to other components can be reduced by about 20%. The spraying length is usually 20 mm, and for a 2.2 m long anchor rod, the length of the part that protrudes out of the well wall is usually 10-15 cm, and by processing a 20 cm heat insulation coating, the exposed part can be completely wrapped.

[0038] In some embodiments, as shown in Figure 4As shown, the heat insulation composite anchoring assembly 10 further comprises an anchor rod tray 300, the anchor rod tray 300 is sleeved outside the protruding well wall part of the anchor rod 200 to be fixedly connected with the anchor rod 200, and the anchor rod tray 300 abuts against the anchor net 100. After the anchor rod tray 300 is fixedly connected with the anchor rod 200, the anchor rod tray 300 can be pressed towards the anchor net 100 to press the anchor net 100 towards the well wall through the acting force, and the acting force between the anchor rod 200 and the anchor rod tray 300 can resist the reaction force exerted by the anchor net 100 on the anchor rod tray 300, so that the anchor rod tray 300 can reliably press the anchor net 100 towards the well wall. Through the plurality of anchor rods 200 and the anchor rod trays 300 fixed by the anchor rods 200, the anchor net 100 can be pressed towards the well wall at multiple positions to limit the sagging of the anchor net 100, thereby further improving the reinforcing effect of the anchor net 100 on the well wall. The outer surface of the anchor rod tray 300 has a second heat insulation structure 310. It can be understood that, in the state that the anchor rod tray 300 contacts the anchor net 100, the heat of the well wall can be conducted to the anchor rod tray 300. By arranging the second heat insulation structure 310 on the outer surface of the anchor rod tray 300, the heat transferred from the anchor net 100 to the anchor rod tray 300 can be reduced, thereby reducing the heat transferred from the anchor net 100 and the anchor rod tray 300 to the mine, and improving the working environment in the mine. It should be noted that the second heat insulation structure 310 can be any structure that can achieve heat insulation. For example, the anchor rod tray 300 is entirely made of a heat insulation material, and the heat insulation material forms the second heat insulation structure 310. For example, the second heat insulation structure 310 can be a heat insulation sleeve arranged on the outer surface of the anchor rod tray 300, and the heat insulation sleeve forms the second heat insulation structure 310.

[0039] In some embodiments, as shown in Figure 5 For example, the anchor rod tray 300 is made of a heat insulation material, and the heat insulation material forms the second heat insulation structure 310. By making the anchor rod tray 300 entirely of a heat insulation material, the second heat insulation structure 310 can have a larger thickness size, thereby improving the heat insulation capacity of the anchor rod tray 300.

[0040] In some embodiments, as shown in Figure 6 For example, the second heat insulation structure 310 comprises a tray heat insulation piece 311, which is located between the anchor rod tray 300 and the anchor net 100, i.e., the tray heat insulation piece 311 is arranged on the outer surface of the anchor rod tray 300 facing the anchor net 100, so that the anchor rod tray 300 can press the anchor net 100 while reducing the heat transferred from the anchor net 100 to the anchor rod tray 300 through the tray heat insulation piece 311. Optionally, the tray heat insulation piece 311 is fixed to the outer surface of the anchor rod tray 300. When the anchor rod tray 300 is installed, the anchor rod tray 300 and the tray heat insulation piece 311 can be installed integrally, thereby improving the convenience of construction.

[0041] In some embodiments, as shown in FIG. 1, the heat insulation composite anchoring assembly 10 comprises a tray heat insulation piece 311 and an anchor net 100, the tray heat insulation piece 311 is arranged on the anchor net 100, and the tray heat insulation piece 311 is directly in contact with the anchor net 100. Figure 7 As shown in FIG. 1, the tray heat insulation piece 311 comprises a heat insulation part 312 and a protective part 313. The heat insulation part 312 is made of a heat insulation material, so as to realize the heat insulation function of the tray heat insulation piece 311. For example, the heat insulation part 312 is a fire-retardant aerogel felt with glass fiber as a skeleton and silica as a dispersed phase. The fire-retardant aerogel felt can be fire-retardant and increase the heat insulation performance of the tray heat insulation piece 311. Optionally, the thickness of the heat insulation part 312 can be 5 mm. The protective part 313 covers the outer surface of the heat insulation part 312, so as to further improve the heat insulation capacity of the tray heat insulation piece 311. It should be noted that the materials of the protective part 313 and the heat insulation part 312 both have heat insulation capacity, and the material of the protective part 313 also has wear resistance, so that the heat insulation part 312 can be protected by the protective part 313. For example, the protective part 313 is a fire-retardant polyethylene-vinyl acetate film (hereinafter referred to as fire-retardant PEVA film for convenience). The PEVA film is wrapped outside the heat insulation part 312 by plastic packaging processing, so as to avoid the failure of the fire-retardant aerogel felt due to the increase of heat conduction caused by the adsorption of water vapor, and increase the waterproof and moisture-proof performance of the tray heat insulation piece 311. At the same time, white glue is attached between the fire-retardant PEVA film and the heat insulation part 312, so as to increase the connection tightness between the two layers, prevent the failure of the plastic packaging layer caused by the local damage of the PEVA film, and increase the wear resistance of the tray heat insulation piece.

[0042] In some embodiments, as shown in FIG. 1, the heat insulation composite anchoring assembly 10 comprises a tray heat insulation piece 311 and an anchor net 100, the tray heat insulation piece 311 is arranged on the anchor net 100, and the tray heat insulation piece 311 is directly in contact with the anchor net 100. Figure 7 As shown in FIG. 1, the heat insulation composite anchoring assembly 10 further comprises a wear-resistant sheet 400. The wear-resistant sheet 400 is clamped between the tray heat insulation piece 311 and the anchor net 100. The wear-resistant sheet 400 is directly in contact with the tray heat insulation piece 311, and the wear-resistant sheet 400 is directly in contact with the anchor net 100. Optionally, the wear-resistant sheet 400 is made of a heat insulation wear-resistant material. The heat insulation wear-resistant material further improves the heat insulation capacity of the heat insulation composite anchoring assembly 10, slows down the wear speed of the tray heat insulation piece 311, and increases the service life of the tray heat insulation piece 311. For example, the wear-resistant sheet 400 is a composite material (hereinafter referred to as PE aluminum foil plate for convenience) composed of aluminum foil and polyethylene film. The wear-resistant sheet 400 is fixed by white glue and fire-retardant PEVA film, and the thickness of the wear-resistant sheet 400 is 0.5 mm. The wear-resistant sheet 400 is suitable for directly contacting with the rock wall, so as to increase the wear resistance of the composite material. At the same time, the PE aluminum foil material can reflect part of the radiant heat of the rock wall, so as to increase the heat insulation performance of the composite material.

[0043] In some embodiments, as shown in FIG. 1, the heat insulation composite anchoring assembly 10 comprises a tray heat insulation piece 311 and an anchor net 100, the tray heat insulation piece 311 is arranged on the anchor net 100, and the tray heat insulation piece 311 is directly in contact with the anchor net 100. Figure 8As shown, the heat insulation composite anchoring assembly 10 further comprises a fixing nut 500 sleeved on the outer part of the anchor rod 200 protruding from the well wall and fixedly connected with the anchor rod 200, and the anchor rod tray 300 is located between the fixing nut 500 and the anchor net 100, that is, the anchor rod tray 300 is clamped between the fixing nut 500 and the anchor net 100, the fixing nut 500 is detachably connected with the anchor rod 200, so that the installation of the anchor rod tray 300 can be facilitated, and the fixing nut 500 can be moved in the direction close to or away from the anchor rod tray 300 by rotating the fixing nut 500, thereby adjusting the pressing force of the anchor rod tray 300 pressing the anchor net 100; wherein the outer surface of the fixing nut 500 has a third heat insulation structure 510, which further reduces the heat transmitted by the anchor net 100 to the mine through the anchor rod tray 300 and the fixing nut 500, and further improves the working environment in the mine.

[0044] It should be noted that the third heat insulation structure 510 can be any structure capable of heat insulation, and optionally, the fixing nut 500 is made of a heat insulation material as a whole to form the third heat insulation structure 510; optionally, as shown in the drawings, Figure 9 As shown, the fixing nut 500 is made of metal as a whole, and the third heat insulation structure 510 comprises a nut heat insulation structure 511 wrapped on the outer surface of the fixing nut 500, so as to improve the structural strength of the fixing nut 500 while improving the heat insulation capacity of the composite nut formed by the fixing nut 500 and the nut heat insulation structure 511, for example, a silicone rubber composite nut, a 2mm thick silicone rubber layer is used for composite adhesive processing on the exposed part of the nut, and the nut is heat insulated by the silicone rubber layer to reduce the heat introduced from the anchor rod.
