Description

Technical Field

[0001] This utility model belongs to the field of protective device technology, specifically a mine roadway blasting impact safety protection device that is easy to disassemble and assemble. Background Technology

[0002] Currently, in mine tunnel excavation and blasting operations, conventional stemming is used to plug the blast holes, and blasting operations are typically carried out with ordinary cover plates or without any protection. Due to insufficient stemming length, excessive explosive charge, or inadequate blast protection, significant blasting vibrations are easily generated. The shockwaves experienced by all equipment and personnel within the tunnel are substantial, and the blast shockwaves also cause soil and rock to fly, potentially damaging on-site equipment and pipelines, such as ventilation equipment and pipes, power supply equipment, water and gas supply equipment, and lighting fixtures. Therefore, protective devices are needed to weaken the shockwaves that could cause equipment damage.

[0003] Currently, some large protective devices are time-consuming and labor-intensive to transport. For example, a large explosion-proof door needs to be installed at the opening on the south side at -440m. The blasting vibration and shock wave generated during blasting may also easily damage the protective device. Because the protective device is in frequent contact with flying rocks or blasting shock waves, the protective device facing the direction of flying rocks or blasting shock waves may be deformed, cracked, or damaged. Existing devices often require replacement of the entire device after partial damage due to the high degree of component integration, resulting in high maintenance costs and affecting the construction progress. To address this issue, we propose a mine roadway blasting impact safety protection device that is easy to disassemble and assemble. Utility Model Content

[0004] The purpose of this utility model is to provide a mine roadway blasting impact safety protection device that is easy to assemble and disassemble, so as to solve the technical problems mentioned in the background art.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Through the designed protective mechanism, the protective plate is connected to the support frame and the support hollow plate by the first and second pivots. After the explosion, it can be quickly folded to be parallel to the bottom plate, reducing the volume and making it easy to move, thus improving the construction efficiency. The flying stones and shock waves generated by the explosion are blocked, reduced and absorbed by the three different structures of the rubber buffer plate, the shock wave resistant plate and the installation plate, which greatly improves the buffering of flying stones and blast shock wave energy of the protective device. The support structure composed of the support frame, the locking stud and the support hollow plate can effectively fix the protective plate.

[0017] (2) By combining the designed internal threaded cylinder, external threaded column and extension rod, the present invention forms a temporary bearing platform above the rubber buffer plate when the protective device is folded. This platform can move and transport some of the plates and tools used in construction. Moreover, the extension rod can limit the plates and tools to prevent them from falling during the movement. This solves the transportation needs of tools and materials in mine roadways and improves the multifunctionality of the protective device. Attached Figure Description

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model provides a technical solution: a mine roadway blasting impact safety protection device that is easy to assemble and disassemble. The protection device can be used to protect on-site equipment in the roadway and reduce the impact of flying rocks and shock waves on the on-site equipment. It includes a protection mechanism, which includes a base plate 102 and a protection plate 101 located on one side of the base plate 102. The top of the protection plate 101 is rotatably connected to the supporting hollow plate 108 through a second pivot on a second bearing 109. The support frame 106 is rotatably connected to the right side of the base plate 102 through a first pivot on a first bearing 105. A first bearing 105 is fixedly installed on the top of one side of the base plate 102. The support frame 106 is rotatably installed on the first bearing 105 through a first pivot. A second bearing 109 is fixedly installed on one side of the top of the protection plate 101. The supporting hollow plate 108 is rotatably installed on the second bearing 109 through a second pivot. The end of the support frame 106 is inserted into the interior of the supporting hollow plate 108 to support the protection plate 101.

[0027] The interior of the supporting hollow plate 108 is connected by a locking stud 107 via threads. The locking stud 107 can fix the support frame 106, so that the top of the support frame 106 is fixed together with the supporting hollow plate 108, and the working end of the locking stud 107 extends to the surface of the support frame 106.

[0028] An mounting plate 114 is fixedly installed on the other side of the protective plate 101. An anti-shock wave plate 113 is fixedly installed on the side of the mounting plate 114. The anti-shock wave plate 113 is usually made of fiber cement board and perforated galvanized steel plate. This structure not only has excellent fire resistance and explosion protection performance, but also can resist impact force and effectively block the explosion shock wave, providing solid protection for surrounding personnel and equipment. A rubber buffer plate 112 is fixedly installed on the surface of the anti-shock wave plate 113. The rubber buffer plate 112, the anti-shock wave plate 113 and the mounting plate 114 are fixed to the protective plate 101 with screws. When wear occurs during use, the rubber buffer plate 112, the anti-shock wave plate 113 and the mounting plate 114 can be removed and replaced. The rubber buffer plate 112 can contact the protective plate 101 between the flying stones and the rubber buffer plate 112, and the rubber buffer plate 112 can buffer the impact force of the flying stones.

[0029] A vertical plate 103 is fixedly installed on the top of one side of the base plate 102. A locking T-shaped screw 104 is threadedly connected inside the vertical plate 103. After the protective plate 101 is folded, the locking T-shaped screw 104 is rotated to the left. Then, the working end of the locking T-shaped screw 104 contacts and clamps the protective plate 101, fixing and limiting the protective plate 101. This prevents the protective plate 101 from moving downwards and contacting the ground due to its own weight during the movement of the protective device, thus avoiding wear. The working end of the locking T-shaped screw 104 extends to the surface of the protective plate 101.

[0030] The protective plate 101 is equipped with casters 100 at all four corners on one side. The casters 100 allow the protective device to be moved after being folded up, making it convenient to enter or leave the mine roadway. The protective plate 101 is fixed with two sets of hanging ears 115 on the front and back. After the protective device is folded up, the casters 100 are facing upwards. At this time, the hanging ears 115 are fixed and the protective device is lifted by a hoist or other lifting device. Then the protective device is flipped over so that the casters 100 face downwards. Then the casters 100 are in contact with the ground. At this time, the rubber buffer plate 112 is at the top. Finally, the protective device can be moved in the roadway by pulling it with a hoist.

[0031] The thickness of the protective plate 101 is greater than the thickness of the base plate 102, and the width of the protective plate 101 is greater than the width of the base plate 102, so that when folded up, the casters 100 are located on the front and back of the base plate 102, and the outer side of the casters 100 extends beyond the support hollow plate 108 and the support frame 106, so that the casters 100 can contact the ground during subsequent movement.

[0032] Example 2

[0033] Please refer to Example 1. Figure 1 , Figure 2 , Figure 4 and Figure 5 Three sets of splicing components are provided on one side of the protective plate 101. Each splicing component includes a U-shaped plate 110 and an L-shaped insert 116 fixed to one side of the protective plate 101. The end of the L-shaped insert 116 can be inserted into the interior of the U-shaped plate 110. After the protective device is deployed, the protective plate 101 from another set of protective devices is spliced ​​onto the front of the protective plate 101. When splicing the front, the end of the L-shaped insert 116 on the protective plate 101 from the other set of protective devices is inserted into the corresponding U-shaped plate 110 on the protective plate 101 of this protective device. The T-shaped stud 117 on the U-shaped plate 110 is rotated and tightened towards the U-shaped plate 110 to fix the L-shaped insert 116 in another set of protective devices. Then, the protective plate 101 on another protective device located in front of this protective device is spliced ​​onto the protective plate 101 in this protective device. This process is repeated to splice the remaining multiple protective devices in a row in front of the protective device until the spliced ​​length meets the width of the mine roadway. At this point, the roadway can be protected, increasing safety during blasting.

[0034] The inside of the U-shaped plate 110 is connected by a fixed T-shaped stud 117 via a thread, and the working end of the fixed T-shaped stud 117 extends to the surface of the L-shaped insert plate 116.

[0035] This utility model, through its designed protective mechanism, establishes a foldable connection between the protective plate 101 and the support frame 106 and the supporting hollow plate 108 via rotating shaft one and rotating shaft two. After blasting, it can be quickly folded to be parallel to the base plate 102, reducing its volume, facilitating movement, and improving construction efficiency. The flying rocks and shock waves generated by the blasting are blocked, reduced, and absorbed by three different structures: the rubber buffer plate 112, the shock wave resistant plate 113, and the mounting plate 114. This greatly improves the buffering effect of the protective device on flying rocks and blasting shock wave energy. The support structure composed of the support frame 106, the locking stud 107, and the supporting hollow plate 108 can effectively fix the protective plate 101.

[0036] Example 3

[0037] Please refer to Example 2. Figures 1-5The protective plate 101 has internally threaded cylinders 201 fixedly installed on both the front and back sides. Before the protective device is moved, the externally threaded post 202 at the end of the extension rod 200 is screwed into the internally threaded cylinder 201. At this time, some plates and tools used in mine roadway construction can be placed on the protective plate 101 for transportation. The extension rod 200 is used to block and limit the movement, preventing the plates and tools from falling off during the movement. This allows a lot of plates and tools to be transported at once, so that the protective device can both protect and transport plates and tools. The internally threaded cylinder 201 is connected to the externally threaded post 202 by threads, and the extension rod 200 is fixedly installed at the end of the externally threaded post 202.

[0038] This utility model combines an internally threaded cylinder 201, an externally threaded column 202, and an extension rod 200 to form a temporary support platform above the rubber buffer plate 112 when the protective device is folded. This allows for the movement and transportation of materials such as boards and tools used in construction. Furthermore, the extension rod 200 can limit the movement of the boards and tools to prevent them from falling during transport. This solves the transportation needs of tools and materials in mine tunnels and enhances the multifunctionality of the protective device.

[0039] Working principle and usage process of this utility model:

[0040] When using this invention, after the protection is completed, the protective plate 101, the supporting hollow plate 108, and the supporting frame 106 are rotated clockwise around the first pivot point to a certain angle and then stopped. (During the rotation, the bottom of the protective plate 101 is initially blocked by the left side of the base plate 102. Then, as the supporting hollow plate 108 and the supporting frame 106 rotate, the bottom of the protective plate 101, blocked by the left side of the base plate 102, rotates clockwise around the second pivot point to a certain angle. Then, as the supporting hollow plate 108 and the supporting frame 106 rotate around the first pivot point, the bottom of the protective plate 101 no longer contacts the left side of the base plate 102.) At this point, the protective plate 101 is positioned above the base plate 102. Next, the free end of the protective plate 101 is rotated counterclockwise around the second pivot point to a certain angle. Finally, the protective plate 101 is positioned relative to the supporting hollow plate 108. 8. With the support frame 106 flush (i.e. parallel, at which point the right side surface of the protective plate 101 is in contact with the lower surface of the support hollow plate 108), loosen the locking stud 107 by turning it upwards. Then, the working end of the locking stud 107 will no longer be in contact with the surface of the support frame 106, releasing the fixation of the support frame 106. Then, move the support hollow plate 108 to the right, causing the protective plate 101 to move along with it. Then, the left end of the support frame 106 will be inserted into the interior of the support hollow plate 108. Finally, tighten the locking stud 107 downwards to fix the support frame 106. Then, rotate the support hollow plate 108, the support frame 106, and the protective plate 101 around the pivot point in a downward direction (i.e., counterclockwise). Then, the left side of the rubber buffer plate 112 on the protective plate 101 will contact the upper surface of the base plate 102, folding the protective device to save space.

[0041] After folding the protective device, since the caster wheel 100 is facing upwards, use a hoist or other lifting device to fix the hanging lug 115 and lift it up (lift the protective device). Then flip the protective device over so that the caster wheel 100 faces downwards, and then the caster wheel 100 contacts the ground. At this time, the rubber buffer plate 112 is at the top position. Finally, use the hoist to pull the protective device and move it in the tunnel.

[0042] Before moving the protective device, tighten the end of the external threaded post 202 on the extension rod 200 into the internal threaded cylinder 201. At this time, multiple plates and tools used in mine roadway construction can be placed above the rubber buffer plate 112. The extension rod 200 limits and blocks the placed plates and tools to prevent them from falling during movement, thus enabling the transportation of plates and tools. Multiple items can be transported at once. When using the protective device, simply unscrew the external threaded post 202 on the extension rod 200 from the internal threaded cylinder 201 to remove it, making disassembly and assembly convenient.

[0043] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
