Description

Technical Field

[0001] The invention relates to the technical field of mine safety equipment, in particular to a safety guardrail device for underground mining of metal mines. Background Art

[0002] Underground mining of metal mines means going deep into the underground ore body through vertical shafts and inclined shafts, and mining metal ores through rock drilling, blasting and support methods according to the process of development and mining. It operates in underground space and relies on ventilation, drainage and transportation systems to ensure safe and efficient operation.

[0003] During underground mining in metal mines, safety guardrail devices are usually required due to the risk of roof collapse, collision hazards caused by vehicle and equipment operation, or the need to divide dangerous areas and safe passages. Safety guardrail devices can effectively prevent people from mistakenly entering dangerous areas, reduce accident injuries, and provide reliable safety separation and protection for the underground working environment.

[0004] However, the existing safety guardrail device for underground mining of metal mines has the following shortcomings: Traditional metal mine underground mining safety guardrail devices use a variety of connectors to splice scattered parts to adapt to the narrow space and complex terrain underground. The parts are transported underground and assembled on site. After being connected, the system is constructed to achieve safety functions such as regional isolation and personnel protection. The specific shortcomings are as follows: Traditional metal mine underground mining safety guardrail devices are limited by the large number of scattered parts and the complicated splicing method, which makes the installation efficiency low and the quality difficult to ensure. In addition, the parts are not easy to adjust and cannot be flexibly adapted to the complex environmental changes at the underground mine site.

[0005] In order to make it convenient for mining personnel to enter specific areas, traditional devices set up protective doors for access control. However, the protective doors are generally closed by physical locking. When danger occurs in the mining area, they cannot be opened quickly for evacuation. Especially when the keys are not properly kept or lost, people are trapped, delaying rescue opportunities and greatly threatening people's lives.

[0006] Therefore, we propose a safety guardrail device for underground mining in metal mines to solve the above-mentioned problems. Summary of the invention

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to the attached Figure 1 -Attached Figure 8 As shown, the present invention provides a technical solution: a safety guardrail device for underground mining in a metal mine, comprising a support mechanism 1, an inner surface wall of the support mechanism 1 is fixedly connected to a guardrail mechanism 2, and an inner surface wall of the support mechanism 1 is fixedly connected to a railing mechanism 3.

[0024] Embodiment 1, according to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the support mechanism 1 includes two groups of bases 101, the tops of the two groups of bases 101 are fixedly connected with external support columns 102, the inner surface walls of the two groups of external support columns 102 are movably inserted with internal support columns 103, one side of the outer wall of two of the two groups of external support columns 102 is fixedly connected with a group of fixing blocks 104, one side of the outer wall of the other two of the two groups of external support columns 102 is provided with a group of fixing grooves 105, and the outer walls of the two groups of fixing blocks 104 are movably inserted into the interior of the two groups of fixing grooves 105, one side of the outer wall of the two groups of fixing blocks 104 is provided with a first limiting groove 106, and the two The inner surfaces of two of the outer support columns 102 are fixedly connected to the mounting plates 107, the tops of the two mounting plates 107 are provided with first slide grooves 108, the inner surfaces of the two first slide grooves 108 are slidably embedded with wedge blocks 109, one side of the outer walls of the two wedge blocks 109 is fixedly connected to a return spring 110, the outer surfaces of the two wedge blocks 109 are fixedly connected to a group of limit frames 111, and the outer surfaces of two of the two groups of limit frames 111 are movably inserted into two of the two groups of first limit grooves 106, and the bottoms of the two groups of inner support columns 103 are fixedly connected to pressure blocks 112.

[0025] The effects achieved by the entire embodiment 1 are as follows: first, by adopting a modular design concept, the support mechanism 1 and the protection mechanism 2 are combined to form a protection door module, and the support mechanism 1 and the railing mechanism 3 are combined to form an isolation railing module. When installing adjacent modules, the adjacent modules must be properly moved first so that the two fixing blocks 104 are accurately inserted into the corresponding fixing grooves 105, so that the two adjacent modules are initially docked. At this time, the positions of the two first limiting grooves 106 are just opposite to the raised parts on the two limiting frames 111. Subsequently, by adjusting the inner support column 103 to rise to adapt to the height of the mine shaft, its rising movement will drive the pressing block 112 to move up synchronously, so that the inclined surface of the pressing block 112 no longer applies pressure to the wedge block 109, and under the elastic force of the two return springs 110, the wedge block 109 will move outward, thereby driving the two limiting frames 111 to expand outward, until the raised parts of the two limiting frames 111 move out of the outer support column 102 and are successfully locked. The two modules are inserted into the corresponding first limiting grooves 106, thereby forming a stable mortise and tenon connection between the two adjacent modules, and this docking method not only connects quickly, but also ensures the stability of the structure, thereby significantly improving the stability and reliability of the guardrail device during use. On the contrary, when the guardrail protection is not needed, the adjacent modules need to be disassembled. First, the two inner support columns 103 are lowered to reduce the volume of the corresponding modules, and the lowering of the inner support columns 103 will drive the pressing block 112 to move downward and re-extrude the wedge block 109. After being squeezed, the wedge block 109 will drive the two limiting frames 111 to move to one side and compress the two return springs 110 at the same time. At this time, the protruding parts of the two limiting frames 111 will be disengaged from the corresponding first limiting grooves 106, thereby realizing the rapid disassembly of the two adjacent modules, and this rapid splicing method greatly improves the installation efficiency of the guardrail device, making the assembly and disassembly process of the entire device more convenient and efficient.

[0026] Embodiment 2, according to Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, one side of the outer wall of the two groups of inner support columns 103 is provided with a plurality of meshing grooves 113, and the inner surface walls of four groups of the plurality of meshing grooves 113 are meshedly connected with gears 114, and the inner surface walls of two of the two groups of gears 114 are fixedly inserted with outer rotating rods 115, and the outer surfaces of the two outer rotating rods 115 are fixedly sleeved with worm wheels 116, and the outer surfaces of the two worm wheels 116 are meshedly connected with worms 117, and one side of the outer walls of the two worms 117 is fixedly connected with knobs 114. 18. The outer walls of the two worm gears 117 are fixedly sleeved with a set of first bearings 119, and the outer walls of the two sets of first bearings 119 are fixedly inserted into two of the two sets of outer support columns 102. The inner walls of the two outer rotating rods 115 are movably inserted with a set of limit bars 120, and the outer walls of the two sets of limit bars 120 are fixedly connected with an inner rotating rod 121. The outer walls of the two outer rotating rods 115 and the two inner rotating rods 121 are fixedly sleeved with second bearings 122.

[0027] The effect achieved by the entire embodiment 2 is as follows: when it is necessary to adjust the height of each module to adapt to the actual working height of the mine shaft, the knob 118 of each module can be rotated respectively, and the rotation of the knob 118 will drive the worm 117 to rotate, and then through the meshing transmission of the worm 117 and the worm wheel 116, the worm wheel 116 and the outer rotating rod 115 are driven to rotate synchronously, and two rectangular limit bars 120 are movably inserted through the inner surface wall of the outer rotating rod 115, and the outer walls of the two limit bars 120 are fixedly connected to the outer wall of the inner rotating rod 121, so that the limiting effect of the two rectangular limit bars 120 Under, ensure that the rotation of the outer rotating rod 115 can synchronously drive the rotation of the inner rotating rod 121, and then, the rotation of the inner rotating rod 121 will further drive the two gears 114 installed thereon to rotate synchronously, and through the meshing transmission between the two gears 114 and the multiple groups of meshing grooves 113, therefore, the rotation of the gear 114 will drive the two inner support columns 103 to rise vertically, thereby realizing the flexible adjustment of the overall height of each module. In this way, the optimal height setting can be provided for each module according to the actual working environment and needs underground in the mine, ensuring that the guardrail device can provide the most effective protection.

[0028] Embodiment 3, according to Figure 6As shown, the protection mechanism 2 includes two first connecting rods 201, the outer walls of the two first connecting rods 201 are each provided with a group of second slide grooves 202, the inner walls of the two second slide grooves 202 are each slidably embedded with a group of sliders 203, a protection rod 204 is fixedly connected between the outer walls of the two groups of sliders 203, a folding connecting rod 205 is movably inserted between the inner walls of a group of protection rods 204, a push block 206 is fixedly connected to one side of the outer wall of one of the two groups of sliders 203, an electric push rod 207 is fixedly connected to one side of the outer wall of the push block 206, and a top of one of the two first connecting rods 201 is fixedly connected to A group of first outer sleeve rods 208, the inner surface walls of a group of first outer sleeve rods 208 are all movably inserted with first inner sleeve rods 209, one side of the outer wall of two of the group of first outer sleeve rods 208 is fixedly connected to an electrical control cabinet 210, a group of first inner sleeve rods 209 are fixedly connected between the tops, an infrared sensor 212 is fixedly installed on one side of the outer wall of the second connecting rod 211, a gas sensor 213 is fixedly installed on the top of the second connecting rod 211, a smoke sensor 214 is fixedly installed on the top of the second connecting rod 211, and a buzzer alarm 215 is fixedly installed on the top of the second connecting rod 211.

[0029] The effects achieved by the entire embodiment 3 are as follows: first, the harmful gas concentration and smoke conditions in the mining area inside the isolation fence are monitored in real time through the gas sensor 213 and the smoke sensor 214. Once the harmful gas exceeds the standard or the smoke concentration is abnormal, these sensors will quickly transmit the alarm signal to the signal acquisition module inside the electrical control cabinet 210. After receiving the signal, the signal acquisition module immediately triggers the buzzer alarm 215 through the control module to generate an emergency alarm to alert the on-site staff. The acquisition module and the control module in the electrical control cabinet 210 are both existing technologies to ensure the accuracy of signal processing and the timeliness of response. When the alarm is triggered, the control module will quickly instruct the electric push rod 207 to start. After receiving the instruction, the telescopic end of the electric push rod 207 will drive the outermost one The sliders 203 are moved, and through the rapid folding linkage effect of the folding connecting rod 205, the two groups of sliders 203 and a group of protective rods 204 connected thereto can be quickly retracted, thereby opening a channel in the protective door module for the staff to evacuate quickly. In addition, in order to cope with other possible emergency situations, when the evacuated personnel approach the protective rod 204, the infrared sensor 212 will detect the approach of the personnel in real time. Once it is detected that there is a person approaching, the infrared sensor 212 will immediately feed back a signal to the control module, and the control module will quickly instruct the electric push rod 207 to start to ensure the smooth opening of the channel. This method provides a safe and efficient evacuation channel for the staff in an emergency through real-time monitoring, rapid response and intelligent control, thereby maximizing the safety of the workers' lives.

[0030] Embodiment 4, according to Figure 7 and Figure 8 As shown, the railing mechanism 3 includes two first railings 301, the tops of the two first railings 301 are each provided with a movable groove 302, the inner surfaces of the two movable grooves 302 are each slidably embedded with a second railing 303, the inner surfaces of the two first railings 301 are each provided with a group of second limiting grooves 304, the inner surfaces of the two groups of second limiting grooves 304 are each movably inserted with limiting blocks 305, and the outer surfaces of the two second railings 303 are fixedly connected to the outer surfaces of the two groups of limiting blocks 305, one of the two first railings 301 and one of the two second railings 303 are each fixedly connected to a group of second outer sleeve rods 306 at the top, the other of the two first railings 301 and the other of the two second railings 303 are each fixedly connected to a group of second inner sleeve rods 307 at the bottom, and the two groups of second inner sleeve rods 307 are The outer wall is movably inserted into the interior of the two groups of second outer rods 306, one side of the outer wall of two of the two groups of outer support columns 102 is fixedly connected to the outer wall of the two first connecting rods 201, one side of the outer wall of two of the two groups of inner support columns 103 is fixedly connected to the outer wall of the second connecting rod 211, one side of the outer wall of one of the two groups of outer support columns 102 is fixedly connected to the outer wall of one of the two first railings 301, one side of the outer wall of one of the two groups of outer support columns 102 is fixedly connected to the outer wall of one of the two second railings 303, one side of the outer wall of one of the two groups of inner support columns 103 is fixedly connected to the outer wall of one of the two second railings 303, and one side of the outer wall of one of the two groups of inner support columns 103 is fixedly connected to the outer wall of one of the two second railings 303.

[0031] The effect achieved by the entire embodiment 4 is as follows: in view of the diversity and complexity of the actual width of the mine shaft, when multiple isolation railing modules are used for splicing, some areas may not be effectively covered. At this time, the two second railings 303 are moved first. Since the two second railings 303 are slidably inserted inside the two first railings 301, the relative distance between the two first railings 301 and the two second railings 303 can be flexibly adjusted by manually moving the two second railings 303, thereby achieving the extension or shortening of the length of the isolation railing module. In this way, the guardrail device can fit the rock wall of the mine shaft more closely, effectively reducing the uncovered area, ensuring the integrity and stability of the guardrail, and the limiting action of the two sets of limit blocks 305 can control the movement range of the two second railings 303, ensuring that the isolation railing module still maintains a stable structural state after adjusting the length.

[0032] The working principle of the whole mechanism is as follows: by adopting a modular design, first, a group of support components inside the support mechanism 1 is combined with the protection mechanism 2 to form a protection door module, and another group of support components is combined with the railing mechanism 3 to form an isolation railing module. According to the actual length requirements of the mine shaft, multiple isolation railing modules and one protection door module can be selected for splicing. The splicing process is simple and quick. It only needs to insert the fixing blocks 104 of the two adjacent modules into the corresponding fixing grooves 105 to achieve preliminary fixation. At this time, the position of the first limiting groove 106 on the fixing block 104 corresponds to the raised part of the limiting frame 111, which prepares for the subsequent stable connection. According to the actual height of the mine shaft, each module is equipped with an adjustment mechanism. By rotating the knob 11 8, it can drive the worm 117 to rotate, and then drive the worm wheel 116 and the outer rotating rod 115 to rotate. Since the inner surface wall of the outer rotating rod 115 is movably inserted with two limit bars 120, and the two limit bars 120 are rectangular in shape, the rotation of the outer rotating rod 115 will synchronously drive the inner rotating rod 121 to rotate, so that the inner rotating rod 121 and the outer rotating rod 115 rotate synchronously, and then drive the two gears 114 to rotate synchronously, and through the meshing transmission of the gears 114 and the multiple groups of meshing grooves 113, the two inner support columns 103 can move vertically upward. At the same time, by utilizing the telescopic cooperation of a group of first outer sleeve rods 208 and a group of first inner sleeve rods 209, and the telescopic effect of the two groups of second outer sleeve rods 306 and the two groups of second inner sleeve rods 307, the protective door module The height of the block and the isolation railing module is adjustable to meet the actual space requirements of the mine, and as the inner support column 103 rises, the pressure block 112 also moves accordingly, and no longer squeezes the wedge block 109. Under the elastic action of the two return springs 110, the wedge block 109 moves outward and drives the two limit frames 111 to move outward, so that the raised parts of the limit frames 111 are stuck in the corresponding first limit grooves 106, thereby forming a stable mortise and tenon connection. This connection method is not only fast, but also can ensure a stable connection between adjacent modules. When it is necessary to disassemble the adjacent modules, it is only necessary to rotate the knob 118 in the opposite direction to move the pressure block 112 downward and squeeze the wedge block 109. After the wedge block 109 is squeezed, it drives the two limit frames 111 Move to one side and compress the reset spring 110, so that the protruding part of the limit frame 111 is separated from the first limit groove 106, thereby realizing quick disassembly. In addition, according to the actual width of the mine shaft, the length of the railing module can be adjusted to make the guardrail fit the shaft wall as much as possible. The actual length of the isolation railing module can be adjusted by the mutual sliding cooperation of the two first railings 301 and the two second railings 303, and the limiting effect of the limit block 305 can prevent the guardrail module from moving excessively. When the guardrail is spliced ​​by multiple modules, the signal output ends of multiple sensor components and alarm components need to be connected to the signal receiving ends inside the electrical control cabinet 210. The signal acquisition and control module inside the electrical control cabinet 210 is responsible for monitoring and processing these signals.The acquisition and control modules inside the electrical control cabinet 210 are all existing technologies. The infrared sensor 212 can detect the situation of people inside the guardrail approaching the guardrail 204. Once the person is detected approaching, the control module inside the electrical control cabinet 210 will start the electric push rod 207. The telescopic end of the electric push rod 207 drives the slider 203 to move, and through the rapid folding linkage of the folding connecting rod 205, the two groups of sliders 203 and a group of guardrails 204 are quickly retracted, so that the protective door module forms a channel for the convenience of staff evacuation, and the gas sensor 213 and the smoke sensor 214 are used to detect the environment of the mining area inside the isolation fence. Once an abnormal situation is detected, such as excessive gas concentration or too high smoke concentration, the sensor will quickly transmit the signal to the signal acquisition module inside the electrical control cabinet 210, and the control module will start the buzzer alarm 215 to generate an alarm sound, and open the fast evacuation channel through the electric push rod 207 to ensure that the internal mining personnel can evacuate quickly.
