Description

Technical Field

[0001] This utility model relates to a mine roadway support device, specifically a rapid mine roadway support device, belonging to the field of mine support technology. Background Technology

[0002] In mining operations, mine roadways serve as the main passageways for pedestrians, transportation, ventilation, and drainage. During the mining and excavation process, in order to support the roof during the movement of the working face, ensure the safety of the working space, mitigate and reduce the movement of the surrounding rock within the roadway, and prevent the collapse of the scattered and damaged surrounding rock, the roadways are continuously supported during the excavation process.

[0003] Existing mine roadway support devices lack anti-tipping functionality. During installation and use, due to uneven road surfaces and uneven stress distribution, these devices are prone to tipping over, affecting support effectiveness and potentially causing safety accidents. Furthermore, the installation and fixing process is cumbersome, requiring multiple manual steps, resulting in low support efficiency and failing to meet the needs of rapid support in mine roadways. Therefore, this paper proposes a rapid support device for mine roadways. Utility Model Content

[0004] This utility model proposes a rapid support device for mine roadways to solve the problems of lack of anti-tipping function, easy tipping, and cumbersome installation and fixing process in the existing technology.

[0005] This utility model is achieved through the following technical solution: a rapid support device for mine roadways, comprising two columns, the outer surfaces of the two columns being provided with a reinforcement mechanism; The reinforcement mechanism includes two extension rods, each of which is slidably connected to the inside of the column. The top of each extension rod is rotatably connected to a hinge ball, and the outer surface of each hinge ball is rotatably connected to a top plate. An auxiliary block is fixedly connected to the outer surface of each column. An inclined support block is rotatably connected to the inside of each auxiliary block. An adjustment block is slidably connected to the inside of each inclined support block. A reinforcement block is rotatably connected to the inside of each adjustment block. Two reinforcement holes are formed inside each reinforcement block. An adjustment assembly is provided on the outer surface of both columns.

[0006] Each of the columns has multiple equal-distance first adjustment holes on its outer surface, and each of the two first adjustment holes is slidably connected to a first positioning bolt, and each first positioning bolt is threadedly connected to an extension rod.

[0007] Each of the columns has a fixed ring on its outer surface, and each of the top plates has a buffer pad on its upper surface.

[0008] Each of the inclined support blocks has multiple equally spaced second adjustment holes on its outer surface. Two of the second adjustment holes are slidably connected to a second positioning bolt, and each second positioning bolt is threadedly connected to the adjustment block.

[0009] The adjustment assembly includes two outer square tubes. The left side of each outer square tube is fixedly connected to the outer surface of one of the columns. An inner square tube is slidably connected inside each outer square tube. The right side of each inner square tube is fixedly connected to the outer surface of the other column.

[0010] Each of the outer square tubes has multiple equally spaced third fixing holes inside, and two of the third fixing holes are slidably connected to third fixing bolts. Each of the third fixing bolts is threadedly connected to the inner square tube.

[0011] This utility model provides a rapid support device for mine roadways, which has the following beneficial effects: This rapid support device for mine roadways forms a multi-directional support system through the coordinated action of inclined support blocks, adjusting blocks, and reinforcing blocks in the reinforcement mechanism. The extension length of the adjusting block within the inclined support block can be adjusted according to the roadway surface flatness and the stress on the columns. The device is then fixed to the roadway surface or sidewall via bolts through the reinforcing holes in the reinforcing blocks. This effectively resists the tendency of columns to tip over due to uneven ground or uneven stress, solving the problem of easy tipping in existing devices. It avoids affecting the support effect or causing safety accidents due to device tipping. The adjusting component can connect two columns and adjust the spacing, forming a stable lateral support structure between the two columns, further improving the overall anti-tipping performance of the device and ensuring stable support in complex mine roadway environments.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0015] Please see Figures 1-4 This utility model embodiment provides a rapid support device for mine roadways, including two columns 1, and a reinforcement mechanism 2 is provided on the outer surface of the two columns 1. The reinforcement mechanism 2 includes two extension rods 201, each of which is slidably connected to the inside of the column 1. Each column 1 has multiple equidistantly arranged first adjustment holes 4 on its outer surface. Each of the two first adjustment holes 4 has a first positioning bolt 5 slidably connected inside it. Each first positioning bolt 5 is threadedly connected to the extension rod 201. The first positioning bolt 5 passes through the first adjustment hole 4 and is threadedly connected to the extension rod 201, which can firmly fix the extension rod 201 inside the column 1, prevent the extension rod 201 from sliding due to force during the support process, ensure the device height is fixed, and ensure the support effect is stable. At the same time, the threaded connection method has high connection strength and can resist the pressure of the tunnel plate on the extension rod 201, avoiding bolt loosening that could cause changes in device height.

[0016] Each extension rod 201 is rotatably connected to a hinge ball 202 at its top end. A top plate 203 is rotatably connected to the outer surface of each hinge ball 202. A retaining ring 6 is fixedly connected to the outer surface of each column 1. A buffer pad 7 is fixedly connected to the upper surface of each top plate 203. The retaining ring 6, fixed to the outer surface of the column 1, reinforces the circumference of the column 1, enhancing its resistance to deformation. During mine roadway support, the column 1 must withstand the pressure of the top plate 203 and lateral impact. The retaining ring 6 disperses the force on the surface of the column 1, preventing bending or deformation due to excessive local stress, ensuring long-term stable support. The buffer pad 7 is placed between the top plate 203 and the roadway slab. When the device supports the roadway slab, the buffer pad 7 absorbs the pressure impact transmitted by the top plate 203, reducing damage to the top plate 203 and extension rod 201 from rigid contact.

[0017] Each column 1 has an auxiliary block 204 fixedly connected to its outer surface. Each auxiliary block 204 has an inclined support block 205 rotatably connected inside. Each inclined support block 205 has an adjusting block 206 slidably connected inside. Each adjusting block 206 has a reinforcing block 207 rotatably connected inside. Each reinforcing block 207 has two reinforcing holes 208 inside. Each inclined support block 205 has multiple equally spaced second adjusting holes 8 on its outer surface. Each of the two second adjusting holes 8 has a second positioning bolt 9 slidably connected inside. Each second positioning bolt 9 is threadedly connected to the adjusting block 206. The second positioning bolt 9 passes through the second adjusting hole 8 and is threadedly connected to the adjusting block 206, which can firmly fix the adjusting block 206 and the inclined support block 205, prevent the adjusting block 206 from sliding during the support process, and ensure the stability of the inclined support. This fixing method is simple to operate and allows the staff to quickly complete the adjustment and fixing, improving the installation efficiency of the device. At the same time, the high strength of the threaded connection can ensure that the support structure resists the tilting force of the column 1 and enhances the overall anti-tilting performance of the device. An adjustment assembly 3 is provided on the outer surfaces of both columns 1. The adjustment assembly 3 includes two outer square tubes 301. The left side of each outer square tube 301 is fixedly connected to the outer surface of one of the columns 1. An inner square tube 302 is slidably connected inside each outer square tube 301. The right side of each inner square tube 302 is fixedly connected to the outer surface of the other column 1. The outer square tubes 301 and inner square tubes 302 slide together to connect the two columns 1 laterally, forming a stable frame structure. Workers can slide the inner square tubes... The position of 302 inside the outer square tube 301 adjusts the distance between the two columns 1, enabling the device to adapt to mine roadways of different widths, expanding the device's applicable range. Furthermore, the horizontally connected outer square tube 301 and inner square tube 302 can transmit the force between the two columns 1. When one column 1 is subjected to a force that tends to tip over, the force can be transferred to the other column 1 through the adjustment component 3, allowing the two columns 1 to jointly resist external forces, enhancing the overall stability and anti-tipping ability of the device, and preventing a single column 1 from tipping over due to excessive force.

[0018] Each outer square tube 301 has multiple equally spaced third fixing holes 10 inside. Two of the third fixing holes 10 are slidably connected to third fixing bolts 11. Each third fixing bolt 11 is threadedly connected to the inner square tube 302. The multiple equally spaced third fixing holes 10 correspond to different positions of the inner square tube 302. After the staff adjusts the distance between the two columns 1, the third fixing bolts 11 are passed through the corresponding third fixing holes 10 and threadedly connected to the inner square tube 302. This can firmly fix the outer square tube 301 and the inner square tube 302, prevent the inner square tube 302 from sliding and causing changes in the distance between the columns 1, ensure the structural stability of the device during the support process, and avoid affecting the support effect due to changes in the distance.

[0019] When using this utility model: the workers move the two columns 1 to the location in the mine roadway that needs support, and adjust the placement distance of the two columns 1 according to the width of the roadway to ensure that the subsequent adjustment components 3 can be effectively connected. Push one of the columns 1 so that the inner square tube 302 slides inside the outer square tube 301 until the distance between the two columns 1 matches the width of the roadway. At this time, select the corresponding third fixing hole 10 on the outer square tube 301, pass the third fixing bolt 11 through the third fixing hole 10 and thread it to the inner square tube 302, tighten the bolt, and complete the lateral fixation of the two columns 1 to form a stable frame structure and improve the overall anti-tipping ability. Pull the extension rod 201 upwards, causing it to slide within the column 1 and lift the roof plate 203. During this process, observe the distance between the roof plate 203 and the tunnel slab. When the buffer pad 7 on the roof plate 203 is about to contact the tunnel slab, stop pulling the extension rod 201. Select the first adjustment hole 4 on the column 1 corresponding to the position of the extension rod 201, pass the first positioning bolt 5 through the first adjustment hole 4 and thread it onto the extension rod 201, tighten the bolt, and fix the height of the extension rod 201. Due to the presence of the hinge ball 202, the roof plate 203 can automatically adjust its angle, ensuring that the buffer pad 7 completely contacts the tunnel slab, ensuring sufficient support area and improving support stability. Rotate the inclined support block 205 to rotate it around the auxiliary block 204 to a suitable support angle, ensuring that the inclined support block 205 can effectively support the column 1. Then, pull the adjusting block 206 to slide it within the inclined support block 205 until the reinforcing block 207 is in contact with the roadway floor or sidewall. Select the corresponding second adjusting hole 8 on the inclined support block 205, pass the second positioning bolt 9 through the second adjusting hole 8 and thread it to the adjusting block 206, tighten the bolt to fix the position of the adjusting block 206. Finally, use bolts to fix the reinforcing block 207 to the roadway floor or sidewall through the reinforcing hole 208 of the reinforcing block 207, completing the installation of the inclined support structure, further enhancing the anti-tipping ability of the column 1, and ensuring the stability of the device during the support process.
