Description

Technical Field

[0001] The present invention belongs to the technical field of underground mining protection devices, and in particular relates to a protection device for underground mining. Background Art

[0002] Underground mining refers to the process of extracting ore from underground deposits by excavating tunnels, chambers, and stopes. For their own safety, workers in underground mining operations generally wear hard hats. However, traditional hard hats can shift if struck by small falling rocks, affecting the worker's field of vision and subsequent protective effectiveness. This requires manual adjustment, making them inconvenient.

[0003] The main mechanism of safety protection of a hard hat is that when heavy objects or debris fall on the head, the space between the lining and the shell of the hat can act as a buffer and reduce shock, dispersing the local high pressure, greatly reducing the force transmitted to the head and playing a role in head protection. However, when the impact force of the falling object reaches a certain level, even if the hard hat disperses some of the stress, the load transmitted to the head and neck of the human body will still cause harm to the human body. There are also some reports of integrated protective equipment in the prior art, such as CN220800125U, which combines a hard hat with a back armor through an OPW airbag electronic generator, but the cost is high and it is difficult to use on a large scale.

[0004] Therefore, those skilled in the art have proposed a protective device for underground mining, which solves the problems raised in the background art through the design of a mechanical structure.

[0005] The above information disclosed in this background technology is only for enhancing understanding of the background technology of the present invention and therefore it may contain information that does not constitute the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention

[0006] In response to the problems raised in the above background technology, the purpose of the present invention is to provide a protective equipment for underground mining in mines, which has the advantages of preventing the deviation of the safety helmet, enhancing the head and neck protection performance, reducing manufacturing costs and facilitating underground operations.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A protective device for underground mining in a mine, comprising:

[0009] The positioning mechanism includes: a clamping seat, a shoulder positioning clamping plate is fixedly installed above the clamping seat, and the two clamping seats are connected by a mounting strap;

[0010] The protective mechanism includes: a protective outer cover, the protective outer cover is fixedly connected to the shoulder positioning clamping plate through a telescopic component, a safety helmet body is provided below the protective outer cover, and a protective goggles is fixedly installed on the safety helmet body;

[0011] The telescopic assembly includes: a top plate, a lifting mechanism connected to the bottom of the top plate, the lifting mechanism is fixedly connected to the shoulder positioning clamping plate, a telescopic mechanism is connected to one side of the top plate, and the telescopic mechanism is fixedly connected to the protective outer cover.

[0012] Furthermore, the telescopic mechanism includes a telescopic cylinder fixedly connected to the top plate and a telescopic column fixedly connected to the protective outer cover.

[0013] Furthermore, the lifting mechanism includes an inflatable seat, a lifting cylinder and a lifting column fixedly connected to the bottom of the top plate, the lifting column is connected below the lifting column, the lifting cylinder is arranged above the inflatable seat, and the inflatable seat is fixedly connected to the shoulder positioning clamping plate.

[0014] Furthermore, the clamping seat is a U-shaped plate structure with a through slot provided therein, a mounting strap provided inside the through slot, and a tension adjustment buckle provided on the mounting strap.

[0015] Furthermore, the protective cover is a hemispherical structure with a notch provided therein, and the helmet body is located in the notch; an elastic member is provided between the helmet body and the protective cover, and the helmet body is movably matched with the protective cover through the elastic member.

[0016] Furthermore, an extrusion cavity is provided inside the lifting cylinder, the lifting column is slidably matched with the extrusion cavity, a baffle is fixedly installed on the peripheral side of the extrusion cavity, and a pressing rod is fixedly installed on the lower surface of the lifting column.

[0017] Furthermore, a circular hole is provided on the baffle, and a lower pressure rod passes through the circular hole. A buffer spring is sleeved on the side surface of the lower pressure rod, one end of the buffer spring is connected to the baffle, and the other end of the buffer spring is connected to the lifting column; the end of the lower pressure rod away from the lifting column is fixedly connected to a compression plate, and a compression chamber is provided inside the inflation seat, and the compression plate and the compression chamber are slidably matched.

[0018] Furthermore, a pipe interface is provided on the side surface of the inflatable seat, which is connected to the inside of the compression chamber, and a delivery pipe is connected to the pipe interface; connecting seats are provided at both ends of the protective goggles, and a jet elbow is provided on the connecting seat, and the delivery pipe is connected to the jet elbow.

[0019] Furthermore, a buffer pad is fixedly installed on the inner lower surface of the shoulder positioning clamping plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention provides a clamping seat and a shoulder positioning clamping plate. When in use, the two U-shaped clamping seats can be clamped on both sides of the worker's armpits respectively, and the two shoulder positioning clamping seats on the top can be fitted with the worker's shoulders. At this time, the main body of the safety helmet can be worn on the worker's head, and the entire device can be stably worn on the worker's body using a mounting strap with an elastic adjustment buckle. When the worker is hit by falling rocks from above while working underground, the limiting effect of the clamping seat, the shoulder positioning clamping plate and the torso can keep the protective cover in its original position, and will not be tilted or offset due to the impact, so there is no need for the worker to make adjustments, thereby improving convenience during use.

[0022] (2) The present invention provides a connecting seat with an air jet bend on the protective goggles on the main body of the safety helmet, and connects the delivery pipe with the inflation seat. Since the falling rocks from above will be accompanied by dust after hitting the main body of the safety helmet, the dust will adhere to the protective goggles on the main body of the safety helmet, thereby affecting the workers' field of vision. After the protective cover of the device is hit, the lifting column and the lifting cylinder will slide together, thereby driving the lower pressure rod to move downward for a distance. The buffer spring can withstand part of the impact force. At the same time, when the compression plate moves downward, it will squeeze the air in the compression chamber, and then the air in the compression chamber will be ejected along the delivery pipe and the air jet bend. The gas discharged from the air jet bend will promptly remove the dust accumulated on the surface of the protective goggles due to the impact, thereby further improving the convenience of using the device.

In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0032] A protective device for underground mining in a mine, such as Figure 1-6 As shown, it includes: a positioning mechanism, which includes: a clamping seat 1, a shoulder positioning clamping plate 5 is fixedly installed above the clamping seat 1, and the two clamping seats 1 are connected by a mounting strap 3; a protective mechanism, which includes: a protective outer cover 13, the protective outer cover 13 is fixedly connected to the shoulder positioning clamping plate 5 through a telescopic component, a safety helmet body 15 is provided below the protective outer cover 13, and a protective goggles 16 is fixedly installed on the safety helmet body 15; a telescopic component, which includes: a top plate 10, a lifting mechanism is connected to the bottom of the top plate 10, the lifting mechanism is fixedly connected to the shoulder positioning clamping plate 5, a telescopic mechanism is connected to one side of the top plate 10, and the telescopic mechanism is fixedly connected to the protective outer cover 13.

[0033] As can be seen from the above, the present invention provides a clamping seat 1 and a shoulder positioning clamping plate 5. When in use, the two U-shaped clamping seats 1 can be clamped on both sides of the worker's armpits, and the two shoulder positioning clamping seats 1 on the top can be fitted with the worker's shoulders. At this time, the safety helmet body 15 can be worn on the worker's head, and the installation strap 3 with an elastic adjustment buckle 4 can be used to stably wear the entire device on the worker's body. When the worker is hit by falling rocks from above while working underground, the limiting effect of the clamping seat 1 and the shoulder positioning clamping plate 5 and the torso can allow the protective cover 13 to maintain its original position, and will not be tilted or offset due to the impact, so there is no need for the worker to make adjustments, which improves convenience during use.

[0034] In some specific embodiments, Figure 1 As shown, the telescopic mechanism includes a telescopic cylinder 11 fixedly connected to the top plate 10 and a telescopic column 12 fixedly connected to the protective outer cover 13 .

[0035] In some examples, the telescopic cylinder 11 is a cylindrical component with a hollow channel, specifically made of metal or high-strength plastic, and is fixed to the top plate 10 by welding or bolts, serving as a guide and support component for the telescopic column 12. The telescopic column 12 is a rod-shaped component that slides with the telescopic cylinder 11, specifically a metal rod with an inner diameter matching that of the telescopic cylinder 11, and is rigidly connected to the protective cover 13 by welding or clamping, forming a telescopic motion transmission structure.

[0036] Specifically, after the telescopic cylinder 11 is fixed to the top plate 10, its internal hollow channel provides a linear constraint for the movement of the telescopic column 12. When the protective cover 13 is subjected to an external impact, the telescopic column 12 slides along the inner wall of the telescopic cylinder 11, converting the impact force into linear displacement, thereby preventing the protective cover 13 from shifting or twisting. When the device is worn, the telescopic column 12 can telescope along the telescopic cylinder 11 to adapt to the shoulder width of different users. The socketed fit of the telescopic column 12 and the telescopic cylinder 11 forms a stable motion path, ensuring that the protective cover 13 maintains its predetermined trajectory under impact loads.

[0037] In some specific embodiments, Figure 2 As shown, the lifting mechanism includes an inflatable seat 7, a lifting cylinder 8 and a lifting column 9 fixedly connected to the bottom of the top plate 10. The lifting cylinder 8 is connected below the lifting column 9. The lifting cylinder 8 is arranged above the inflatable seat 7. The inflatable seat 7 is fixedly connected to the shoulder positioning clamping plate 5.

[0038] In some examples, the inflatable seat 7 refers to a sealed container with a compression chamber inside, which can be made of metal or high-strength plastic and filled with compressed gas to absorb impact energy through gas compression.

[0039] In some examples, the lifting cylinder 8 is a columnar structure with an internal sliding cavity. Specifically, a hollow cylinder can be used to form a sliding fit with the lifting column 9 to support the lifting column 9 and limit its movement trajectory.

[0040] In some examples, the lifting column 9 refers to a rigid rod fixedly connected to the top plate 10 , and can be made of aluminum alloy or carbon steel, and is used to transfer the impact force borne by the protective cover 13 to the lifting cylinder 8 and the inflatable seat 7 .

[0041] Specifically, when the protective cover 13 is impacted by a falling object, the top plate 10 drives the lifting column 9 to slide along the interior of the lifting cylinder 8, forming a first-level cushioning mechanism. The fixed connection between the inflatable seat 7 and the shoulder positioning clamping plate 5 disperses the residual impact force through the mounting strap 3 to the shoulders, preventing it from being concentrated on the cervical spine. This effectively reduces the load intensity transmitted to the head and neck area when the protective cover 13 is impacted. The gas compression cushioning provided by the inflatable seat 7 and the mechanical support provided by the lifting cylinder 8 jointly prevent overload damage to the cervical spine. Simultaneously, the shoulder positioning clamping plate 5 evenly distributes the residual force to the load-bearing area of ​​the body, avoiding localized stress concentration.

[0042] In some specific embodiments, Figure 2 As shown, an extrusion chamber 21 is opened inside the lifting cylinder 8, and the lifting column 9 slides in cooperation with the extrusion chamber 21. A baffle 22 is fixedly installed on the inner peripheral side of the extrusion chamber 21, and a downward pressure rod 24 is fixedly installed on the lower surface of the lifting column 9.

[0043] In some specific embodiments, Figure 2 As shown, a circular hole is provided on the baffle 22, and a lower pressure rod 24 passes through the circular hole. A buffer spring 23 is sleeved on the side surface of the lower pressure rod 24. One end of the buffer spring 23 is connected to the baffle 22, and the other end of the buffer spring 23 is connected to the lifting column 9; the end of the lower pressure rod 24 away from the lifting column 9 is fixedly connected to a compression plate 25, and a compression chamber 20 is provided inside the inflation seat 7, and the compression plate 25 slides in cooperation with the compression chamber 20.

[0044] Specifically, the downward pressure rod 24 moves downward synchronously with the lifting column 9, pushing the compression plate 25 within the compression chamber 20 of the inflatable seat 7. The gas in the compression chamber 20 is squeezed and generates a reaction force, forming a second-level buffer. This two-stage buffering structure converts impact kinetic energy into gas compression energy and mechanical friction energy, effectively reducing the load transmitted to the human head and neck.

[0045] The buffer spring 23 is compressed between the baffle 22 and the lifting column 9. The spring's elastic deformation absorbs some of the impact energy, creating a mechanical buffer. The remaining impact force drives the compression plate 25 at the end of the lower lever 24 downward along the compression chamber 20. The air within the compression chamber 20 is squeezed, creating an air cushion effect. The reaction force generated by the compressed air further attenuates the impact energy, creating a pneumatic buffer. During this process, the elastic restoring force of the buffer spring 23 and the air pressure resistance of the compression chamber 20 work together to continuously attenuate the kinetic energy in the impact load's transmission path, allowing the lifting mechanism to recover.

[0046] In some specific embodiments, Figure 1 and Figure 2As shown, a pipe interface 27 is provided on the side of the inflation seat 7, the pipe interface 27 is connected to the interior of the compression chamber 20, and a delivery pipe 19 is connected to the pipe interface 27; both ends of the protective goggles 16 are provided with a connecting seat 17, and a jet elbow 18 is provided on the connecting seat 17, and the delivery pipe 19 is connected to the jet elbow 18.

[0047] In some examples, the pipe interface 27 refers to a ventilation connection component provided on the outer wall of the inflation seat 7 , and can be implemented by a threaded interface or a quick plug-in structure.

[0048] In some examples, the connecting seat 17 refers to a supporting component fixed on both sides of the protective goggles 16, which can be specifically implemented by an injection-molded plastic base, and is used to support the jet elbow 18 and maintain its jet direction.

[0049] In some examples, the jet elbow 18 refers to an air-guiding component with a curved path, which can be specifically implemented by a stainless steel bellows or a pressure-resistant plastic elbow, and is used to guide the airflow of the delivery pipe 19 to the surface of the protective goggles 16.

[0050] In a specific example, a flat nozzle, such as a slit structure with a width of 3-5 mm, can be provided at the end of the jet elbow 18 to diffuse the airflow in a fan-shaped manner to cover the surface of the protective goggles 16. A sealing ring, such as a fluororubber seal, can be added to the connection between the pipe interface 27 and the delivery pipe 19 to prevent gas leakage.

[0051] Specifically, since the falling rocks from above will be accompanied by dust after hitting the protective outer cover 13, this dust will adhere to the protective goggles 16, thereby affecting the workers' field of vision. When the inflatable seat 7 is subjected to external pressure, the gas in the compression chamber 20 is squeezed into the pipe interface 27 and transmitted to the jet elbow 18 through the delivery pipe 19. The airflow forms a directional jet along the curved path of the jet elbow 18, directly acting on the surface of the protective goggles 16, and promptly removes the dust accumulated on the surface due to the impact, thereby further improving the convenience of using this device. The connecting seat 17 fixes the injection angle of the jet elbow 18 to ensure that the airflow forms effective contact with the surface of the eyepiece and avoid cleaning blind spots.

[0052] In some specific embodiments, Figure 1 and Figure 4 As shown, the clamping seat 1 is a U-shaped plate structure with a through slot 2 provided therein. A mounting strap 3 is provided inside the through slot 2 , and a tension adjustment buckle 4 is provided on the mounting strap 3 .

[0053] In some examples, the U-shaped plate structure refers to a plate-like component with a U-shaped curved profile, which can be specifically realized by stamping a steel plate. The structure forms an embracing support interface, increasing the contact area with the human shoulder.

[0054] In some examples, the through slot 2 refers to a through slot that passes through both sides of the clamping seat 1, which can be specifically realized by milling. Its function is to provide a directional threading path for installing the strap 3 and constrain the lateral sliding range of the strap.

[0055] In some examples, the mounting strap 3 refers to a belt-shaped connector for connecting two clamping seats 1 , and can be specifically implemented by a nylon braided strap, which forms a closed-loop connection structure through the groove 2 .

[0056] In some examples, the tension adjustment buckle 4 refers to a locking device for adjusting the length of the strap, which can be specifically implemented by a Japanese-shaped plastic buckle, which locks the strap length through tooth-shaped engagement.

[0057] Specifically, the clamping seat 1 of the U-shaped plate structure forms three-point contact with the human shoulder, and generates a covering force through elastic deformation when worn. The through slot 2 extends longitudinally along the plate body, and the mounting strap 3 passes through the through slot 2 to form a closed loop, with its two ends connected to the two clamping seats 1 respectively. When the tension adjustment buckle 4 is operated, the effective length of the mounting strap 3 in the through slot 2 is adjusted so that the spacing between the clamping seats 1 can adapt to the shoulder width of different users. The double-sided support of the U-shaped structure can form a torque balance, prevent the device from overturning when impacted by external force, and improve the stability of the device. At the same time, the coordinated use of the through slot 2 and the tension adjustment buckle 4 realizes the adjustment of the length of the mounting strap 3, so that the device can adapt to the shoulder size of users of different body shapes.

[0058] In some specific embodiments, Figure 3 and Figure 5 As shown, the protective cover 13 is a hemispherical structure with a notch formed therein, and the helmet body 15 is located in the notch; an elastic member 14 is provided between the helmet body 15 and the protective cover 13 , and the helmet body 15 is movably engaged with the protective cover 13 through the elastic member 14 .

[0059] Specifically, when the protective cover 13 is impacted by a rockfall, its hemispherical surface disperses the impact force tangentially, reducing localized stress concentration. The helmet body 15 is constrained within the notch, preventing overall displacement due to the impact. When the impact energy is transferred to the elastic member 14, it partially offsets the vertical impact load.

[0060] In some examples, the elastic member 14 can be a spring or a connecting member made of other elastic materials, as long as it can connect the helmet body 15 and the protective cover 13 and have a certain buffering effect.

[0061] In some embodiments, such as Figure 1 and Figure 6 As shown, a buffer pad 6 is fixedly installed on the inner lower surface of the shoulder positioning clamping plate 5.

[0062] In some examples, the cushioning pad 6 is a shock-absorbing component made of an elastic material, specifically rubber, silicone, or polyurethane foam, which absorbs impact energy through the material's inherent elastic deformation. By adding the cushioning pad 6, while maintaining the original securing function of the shoulder positioning clamping plate 5, the elastic material's compressive deformation properties are utilized to convert localized concentrated loads into distributed loads, effectively reducing the impact force on human tissue.

[0063] Workflow:

[0064] When the user puts on the helmet, they first put the helmet body 15 on their head, adjust the telescopic cylinder 11 and the telescopic rod 12 to match the width of their shoulders; extend their arms into the U-shaped positioning mechanism composed of the clamping seat 1 and the positioning clamping plate 5, and adjust the mounting strap 3 through the elastic adjustment buckle 4 to make the equipment fit the body. When working underground, when the protective cover 13 is impacted by falling objects, the top plate 10 drives the lifting column 9 to slide along the inside of the lifting cylinder 8, forming a first-level buffer; the gas compression buffer in the inflatable seat 7 forms a second-level buffer, and the buffer pad 6 in the shoulder positioning clamping plate 5 forms a third-level buffer, reducing the impact load on the shoulders and neck and preventing the protective cover 13 from shifting. The elastic member 14 on the helmet body 15 forms a buffer for the head, reducing the impact load on the head. When falling objects hit the protective cover 13, dust is often generated. At this time, the impact force drives the compression plate 25 at the end of the lower pressure rod 24 to slide downward along the compression chamber 20. The air in the compression chamber 20 is squeezed and guided from the delivery pipe 19 to both sides of the protective goggles 16, and the protective goggles 16 are cleaned through the jet elbow 18.
