Description

Technical Field

[0001] This utility model relates to a protective device, specifically a blasting safety protection device for mining engineering, belonging to the field of mining engineering technology. Background Technology

[0002] Mining engineering is a comprehensive engineering discipline involving the exploration, mining, processing and management of mineral resources. It aims to develop underground or surface mineral resources efficiently, safely and environmentally. In mining engineering, blasting is a common method of rock breaking and mining. However, the flying rocks and shock waves generated during blasting can pose serious safety threats to the surrounding environment and workers. Therefore, protective mechanisms need to be installed to prevent injuries caused by flying rocks and shock waves.

[0003] Chinese Patent Publication No. CN223037039U discloses a blasting safety protection device for mining engineering, relating to the field of safety protection device design technology. It includes a fixed base, an explosion-proof protection unit, and a water spray dust suppression unit. The fixed base is provided with four rectangular arrays of grounding pins, which connect to the outside via the grounding pins. An explosion-proof protection unit is provided on the upper surface of the fixed base. The explosion-proof protection unit has a protective baffle with a water spray dust suppression unit. The explosion-proof protection unit includes a protective baffle, connecting snap-fit ​​posts, a flexible explosion-proof pad, an explosion-proof reinforcing strip, a triangular fixing seat, a connecting fixing block, and a top explosion-proof plate.

[0004] However, the inventor of the above-mentioned device believes that there are certain defects. The above-mentioned device uses a flexible explosion-proof pad for protection. When encountering high-intensity explosion, the explosion-proof pad loses its buffering function after the compression deformation reaches its limit. The impact energy acts directly on the protective device, which can easily cause damage to the device. Therefore, this utility model provides a blasting safety protection device for mining engineering. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this utility model is to provide a blasting safety protection device for mining engineering in order to solve the above-mentioned problems. This device addresses the issue that in the prior art, after the explosion-proof pad reaches its compression deformation limit, it loses its buffering function, and the impact energy acts directly on the protection device, which can easily cause damage to the device.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: a blasting safety protection device for mining engineering, comprising a fixed frame and a protective mechanism installed on one side of the fixed frame. The protective mechanism includes a protective plate installed on one side of the fixed frame, a connecting cylinder fixedly connected to one side of the protective plate, a through hole corresponding to the connecting cylinder on the fixed frame, a first buffer mechanism on one side of the fixed frame, the first buffer mechanism including a connecting seat installed on one side of the fixed frame, an elastic mechanism inside the connecting seat, a second buffer mechanism on the connecting cylinder, the first buffer mechanism including an exhaust chamber opened at one end of the connecting cylinder, a piston plate slidably connected inside the exhaust chamber, a through groove on the connecting cylinder, a connecting rod fixedly connected to the bottom of the piston plate, one end of the connecting rod extending into the through groove, a connecting slide rod fixedly connected to the bottom of the connecting rod, the connecting slide rod contacting one side of the fixed frame, and an exhaust hole communicating with the exhaust chamber at one end of the connecting cylinder, the diameter of the exhaust hole being millimeters.

[0007] Preferably, a fixed slide rod is fixedly connected inside the connecting seat, and two sliding blocks are slidably connected on the fixed slide rod. One end of each sliding block is hinged to a pressing rod, and the other end of the pressing rod is hinged to one side of the fixed frame. The elastic mechanism includes a first spring sleeved on the outer surface of the fixed slide rod. When the connecting seat moves closer to the fixed frame, the pressing rod pushes the sliding block to slide on the fixed slide rod to compress the first spring for buffering.

[0008] Preferably, one side of the protective plate has a slot corresponding to the connecting seat, and the connecting seat is inserted into the slot. The connecting seat is installed on one side of the protective plate through the slot.

[0009] Preferably, the other end of the connecting tube has a mounting cavity, and a plurality of sliding pins are slidably connected to the inner bottom wall of the mounting cavity. One end of each sliding pin extends to the outer surface of the connecting tube, and the sliding pin abuts against the inner side wall of the fixing frame. When the connecting tube is inserted into the through hole, the reverse withdrawal of the connecting tube is restricted by the sliding pins abutting against the inner side wall of the fixing frame. Preferably, a rotating disk is rotatably connected inside the connecting sleeve, and a pressing groove is formed on the rotating disk. A connecting slider is fixedly connected to the top of the sliding pin, and the connecting slider slides inside the pressing groove. A rotating rod is fixedly connected to the top of the rotating disk, and the rotating rod is rotatably connected to the other end of the connecting sleeve. By rotating the rotating rod, the rotating disk is driven to rotate inside the mounting cavity. The pressing groove presses the connecting slider, causing the sliding pin to slide inside the mounting cavity, so that one end of the sliding pin slides and extends on the outer surface of the connecting sleeve.

[0010] Preferably, side guard plates are rotatably connected to both sides of the protective plate, and the protective plate is provided with a limiting mechanism to restrict the rotation of the side guard plates, thereby protecting both sides of the device through the side guard plates.

[0011] Preferably, a fixed plate is fixedly connected to the bottom of the side guard plate pivot, and the fixed plate has a circumferential array of positioning holes. The limiting mechanism includes a fixing bolt threaded to the bottom of the guard plate. The fixing bolt is inserted into the positioning hole. By inserting the fixing bolt into the positioning hole on the fixed plate, the rotation of the side guard plate pivot is limited, thereby fixing the position of the side guard plate.

[0012] Preferably, a second spring is fixedly connected to the top of the piston plate, and the connecting slide rod slides inside the through groove. Under the action of the second spring, the piston plate slides back to its original position when it is not under force.

[0013] This utility model provides a blasting safety protection device for mining engineering, which has the following beneficial effects: 1. This device mounts the protective mechanism on one side of the fixed frame by inserting the connecting sleeve on the side of the protective plate into the through hole. When flying stones generated by the blasting hit the protective plate, the elastic mechanism inside the connecting seat buffers the impact force. As the protective plate slides towards the fixed frame upon impact, it pushes the connecting slide rod to slide inside the through groove. Under the connecting action of the connecting rod, the piston plate is pushed to slide inside the exhaust chamber, allowing the air inside the exhaust chamber to be discharged through the exhaust hole. Because the diameter of the exhaust hole is small, the gas can only be discharged at a relatively slow speed, further reducing the impact force generated by flying stones hitting the protective plate and improving the protective effect of the protective plate.

[0014] 2. The device protects both sides of the device by setting side guards, or by flipping the side guards to be parallel to the protective plate to expand the protection area. The position of the side guards is fixed by setting fixing bolts and fixing plates. The sliding pin is used to drive the sliding pin to slide from the inside of the mounting cavity after the connecting tube is inserted into the through hole, thereby restricting the reverse withdrawal of the connecting tube. Under the action of the elastic mechanism inside the connecting seat, the sliding pin is kept in a tight state against the inner side wall of the fixing frame. Attached Figure Description

[0017] This utility model provides a blasting safety protection device for mining engineering.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A blasting safety protection device for mining engineering includes a fixed frame 1 and a protective mechanism installed on one side of the fixed frame 1. The protective mechanism includes a protective plate 2 installed on one side of the fixed frame 1. A connecting tube 3 is fixedly connected to one side of the protective plate 2. The fixed frame 1 has a through hole 11 corresponding to the connecting tube 3. The connecting tube 3 is cylindrical. The protective plate 2 is installed on one side of the fixed frame 1 by inserting the connecting tube 3 into the through hole 11. The top of the fixed frame 1 is provided with an arc-shaped top plate. The bottom of the fixed frame 1 is provided with an installation hole for fixing piles. A reinforcing rod is fixedly connected to the other side of the fixed frame 1. The protective surface of the protective plate 2 is provided with a buffer pad.

[0019] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The fixed frame 1 has a first buffer mechanism on one side. The first buffer mechanism includes a connecting seat 4 installed on one side of the fixed frame 1. The connecting seat 4 has an elastic mechanism inside. The protective plate 2 has a slot 22 corresponding to the connecting seat 4 on one side. The connecting seat 4 is inserted into the slot 22. When the protective plate 2 is impacted and slides closer to the fixed frame 1, the impact of the protective plate 2 is buffered by the elastic mechanism inside the connecting seat 4. When the protective plate 2 is installed, the connecting seat 4 is inserted into the slot 22.

[0020] Please refer to it again. Figure 1 , Figure 2 and Figure 5The connecting sleeve 3 is equipped with a second buffer mechanism. The first buffer mechanism includes an exhaust chamber 32 at one end of the connecting sleeve 3. A piston plate 7 is slidably connected inside the exhaust chamber 32. A through groove 33 is provided on the connecting sleeve 3. A connecting rod 71 is fixedly connected to the bottom of the piston plate 7. One end of the connecting rod 71 extends into the through groove 33. A connecting slide rod 72 is fixedly connected to the bottom of the connecting rod 71. The connecting slide rod 72 contacts one side of the fixing frame 1. An exhaust hole 34 communicating with the exhaust chamber 32 is provided at one end of the connecting sleeve 3. The diameter of the exhaust hole 34 is 5 mm. When the protective plate 2 is impacted and pushes the connecting sleeve 3 in the through groove 32, the first buffer mechanism provides a second buffer mechanism. The internal sliding of the insertion hole 11 is pushed by the side of the fixing bracket 1 to push the connecting slide rod 72 to slide inside the sliding groove 33. Under the connection of the connecting rod 71, the piston plate 7 slides upward inside the exhaust chamber 32 to discharge the air inside the exhaust chamber 32 through the exhaust hole 34. Since the diameter of the exhaust hole 34 is small, the gas can only be discharged at a relatively slow speed. The top of the piston plate 7 is fixedly connected to the second spring 8. The connecting slide rod 72 slides inside the sliding groove 33. Under the action of the second spring 8, the piston plate 7 slides further to buffer the sliding of the piston plate 7 inside the exhaust chamber 32 and slides back to its original position when the piston plate 7 is not under force.

[0021] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The connecting seat 4 is internally fixedly connected to a fixed slide rod 41. Two sliding blocks 42 are slidably connected to the fixed slide rod 41. One end of each sliding block 42 is hinged to a pressing rod 43. The other end of the pressing rod 43 is hinged to one side of the fixed frame 1. The elastic mechanism includes a first spring 44 sleeved on the outer surface of the fixed slide rod 41. When the connecting seat 4 slides closer to the fixed frame 1, the pressing rod 43 pushes the two sliding blocks 42 away from each other and the first spring 44 is compressed to buffer the impact force on the connecting seat 4.

[0022] Please refer to it again. Figure 1 and Figure 2Both sides of the protective plate 2 are rotatably connected to side guard plates 21. The protective plate 2 is provided with a limiting mechanism to restrict the rotation of the side guard plates 21. The bottom of the rotating shaft of the side guard plate 21 is fixedly connected to a fixing plate 23. The fixing plate 23 has a circumferential array of positioning holes. The limiting mechanism includes a fixing bolt threaded to the bottom of the protective plate 2. The fixing bolt is inserted into the positioning hole. Both ends of the side guard plate 21 are fixedly connected to rotating shafts. The side guard plate 21 rotates on the protective plate 2 through the rotating shafts. By rotating the side guard plate 21, the included angle between the protective plate 2 and the side guard plate 21 can be adjusted. The side guard plate 21 can protect the two sides of the device, or the side guard plate 21 can be flipped to be parallel to the protective plate 2 to expand the protection area. The position of the side guard plate 21 is fixed by the fixing bolts and the fixing plate 23.

[0023] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The other end of the connecting tube 3 is provided with an installation cavity 31. Multiple sliding pins 5 are slidably connected to the inner bottom wall of the installation cavity 31. One end of the sliding pin 5 extends to the outer surface of the connecting tube 3. The sliding pin 5 abuts against the inner side wall of the fixing frame 1. There are four sliding pins 5, which are distributed in a circumferential array inside the installation cavity 31. When the connecting tube 3 is inserted into the through hole 11, the sliding pin 5 is driven to slide out from the inside of the installation cavity 31, so that the sliding pin 5 abuts against the inner side wall of the fixing frame 1, thus completing the quick installation and fixing of the protective plate 2. The inner bottom wall of the installation cavity 31 is fixed with a fixed slide rail to support the sliding of the sliding pin 5.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting tube 3 is rotatably connected to a rotating disk 6, which has a pressing groove 61. The top of the sliding pin 5 is fixedly connected to a connecting slider 51, which slides inside the pressing groove 61. The top of the rotating disk 6 is fixedly connected to a rotating rod 62, which is rotatably connected to the other end of the connecting tube 3. Rotating the rotating rod 62 drives the rotating disk 6 to rotate inside the mounting cavity 31. The pressing groove 61 presses the connecting slider 51 to control the sliding of the sliding pin 5 inside the mounting cavity 31.

[0025] Working principle: The fixing stake is placed in a suitable position and inserted into the installation hole to fix the position of the fixing frame 1. The connecting tube 3 on the side of the protective plate 2 is inserted into the through hole 11, and the connecting seat 4 is inserted into the slot 22. Then, the rotating rod 62 at one end of the connecting tube 3 is rotated to drive the rotating disk 6 to rotate inside the installation cavity 31. The squeezing groove 61 squeezes the connecting slider 51, causing multiple sliding pins 5 to slide outward from the inside of the installation cavity 31, so that the sliding pins 5 abut against the inner side wall of the fixing frame 1, completing the quick installation of the protective plate 2. The side guard plate 21 is rotated to protect the two sides of the device. Then, the side guard plate 21 is flipped to a horizontal position to expand the protection area of ​​the front of the protective mechanism.

[0026] When the flying rocks generated by the blasting hit the protective plate 2, the impact force pushes the protective plate 2 to slide towards the fixed frame 1. The squeezing rod 43 pushes the two sliding blocks 42 away from each other, and the first spring 44 is squeezed to buffer the impact force on the connecting seat 4. While the protective plate 2 slides towards the fixed frame 1 after being hit, it pushes the connecting slide rod 72 to slide inside the through groove 33. Under the connection of the connecting rod 71, it pushes the piston plate 7 to slide inside the exhaust chamber 32, so that the air inside the exhaust chamber 32 is discharged through the exhaust hole 34. Since the diameter of the exhaust hole 34 is small, the gas can only be discharged at a relatively slow speed, which further reduces the impact force generated by the flying rocks hitting the protective plate 2. The second spring 8 inside the exhaust chamber 32 further buffers the sliding of the piston plate 7.
