Description

Technical Field

[0001] This utility model relates to the field of auxiliary boot removal device technology, and more specifically, to a mining boot removal device. Background Technology

[0002] In harsh working environments such as coal mines and coal washing plants, miners' leather boots often become difficult to remove due to coal dust, mud, and slippery conditions. Currently, miners face several problems when removing their boots after work, especially when physically exhausted: First, miners are accustomed to standing on one leg with the other raised to remove their boots. This posture can easily lead to imbalance on slippery ground or when wearing heavy, warm clothing, increasing the risk of slipping and falling. Second, without auxiliary tools, miners often need to assist each other to remove their boots, which not only increases the hygiene risks from contact but may also lead to injuries from improper force. Finally, manually removing boots is time-consuming and laborious. The prolonged process not only depletes miners' physical strength but can also cause emotional distress, negatively impacting their physical and mental health.

[0003] Meanwhile, existing boot-removal aids are mostly designed for the civilian market, such as homes and outdoor sports, lacking specific design for the characteristics and needs of special environments like coal mines. These tools often lack sufficient strength and durability, making them unsuitable for the harsh underground environment of coal mines, and their size and shape may not conform to the structure of miners' boots, resulting in poor performance. Furthermore, existing boot-removal aids do not consider the miner's posture and balance during boot removal, lacking effective support structures and failing to effectively prevent slips and falls during the process.

[0004] Therefore, existing boot removal aids cannot fully address the practical difficulties faced by coal miners when removing their boots, exhibiting problems such as insufficient stability, poor adaptability, and inconvenience in use; especially under conditions of physical exhaustion and harsh environments, the effectiveness of these tools is even more limited. To address these issues, there is an urgent need for a specially designed self-service boot removal device for coal mines to meet the needs of miners in specific environments and improve the safety and efficiency of the boot removal process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 4 As shown, an embodiment of this utility model provides a mining boot removal device, including: a base 10, a handrail structure, and a boot removal structure 20; the handrail structure is disposed on the top surface of the base 10 facing upwards; the boot removal structure 20 is adjustablely disposed on the base 10, and the height of the boot removal structure 20 is adapted to the protruding heel of the mining boot; the interior of the boot removal structure 20 has a groove 21, and the boot removal structure 20 also has a horizontally oriented opening 22, which communicates with the groove 21; wherein, the horizontal opening size of the opening 22 is adjustable; when removing the boot, the handrail structure is used to support the human body, the mining boot enters the groove 21 through the opening 22, and the protruding heel is limited and engaged with the boot removal structure 20 to remove the boot.

[0028] This invention utilizes a base 10, a handrail structure, and a boot removal structure 20 to work together, achieving quick and stable boot removal with a simple structure. The handrail structure provides convenient support for workers during boot removal. The adjustable horizontal opening 22 makes this invention applicable to various types of mining boots. It not only simplifies the boot removal process and improves efficiency but also significantly enhances safety, solving the problem of difficult boot removal for frontline coal miners. It eliminates slips and falls during boot removal, maximizing miners' safety and reducing the probability of workplace injuries caused by slips and falls, thus lowering the operating costs of safe mine production. In actual underground use, it has been found that safety accidents caused by boot removal for frontline coal miners have significantly decreased. This invention reduces the economic losses and personal injuries caused by work-related injuries, minimizes injuries to miners due to improper boot removal, and saves significant time and energy. It has significant economic and social benefits in improving miner satisfaction, reducing work injury compensation, and creating a safer working environment. Furthermore, the mine boot removal device proposed in this invention is easy to manufacture and maintain, making it widely applicable in coal mines and similar industries, and contributing to raising labor protection standards across the entire industry. This invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of existing boot removal auxiliary tools that fail to adequately address the practical difficulties faced by coal miners when removing their boots, lack stability, have poor adaptability, and are inconvenient to use, making it suitable for large-scale promotion and use.

[0029] like Figure 1 and Figure 3 As shown, the boot removal structure 20 includes a support base 23, a first adjusting arm 24, and a second adjusting arm 25. The support base 23 is detachably mounted on the base 10, and the top of the support base 23 is spaced apart from the top surface of the base 10 by a first height, which is adapted to the height of the protruding heel of the mining boot. The first adjusting arm 24 and the second adjusting arm 25 are respectively rotatably mounted on the top of the support base 23, and a groove 21 and an opening 22 are formed between the first adjusting arm 24 and the second adjusting arm 25. When removing the boot, the protruding heel is respectively limited and engaged with the bottom of the first adjusting arm 24 and the second adjusting arm 25. By rotating the first adjusting arm 24 and the second adjusting arm 25, the horizontal opening size of the opening 22 is adjusted.

[0030] The boot removal structure includes a support base 23, a first adjusting arm 24, and a second adjusting arm 25. The support base 23 is detachably mounted on the base 10, with its top maintaining a first height distance from the top surface of the base 10 to match the protruding heel of the mining boot. The first adjusting arm 24 and the second adjusting arm 25 can rotate horizontally on the top of the support base 23. The groove 21 and opening 22 formed between them allow the mining boot to enter the groove 21 through the opening 22, while ensuring that the protruding heel forms a limiting fit with the bottom of the adjusting arm. By adjusting the position of the first adjusting arm 24 and the second adjusting arm 25, the horizontal opening size of the opening 22 can be dynamically changed to accommodate different styles of mining boots, ensuring a smooth boot removal process.

[0031] The aforementioned design enhances the versatility of the boot removal device and ensures that miners can easily remove their boots even when physically exhausted, improving convenience and safety. In practical use, miners can maintain their balance using the handrail structure and utilize the adjustable function of the boot removal mechanism to quickly and stably remove their boots, effectively preventing the risk of slipping or falling due to improper boot removal, improving working conditions, and increasing work efficiency. Furthermore, the boot removal device is simple to manufacture and maintain, can be processed using common materials, is inexpensive, and is easy to widely promote in the coal mining industry, which is of great significance for improving labor protection standards and reducing the burden on miners.

[0032] Specifically, the boot removal structure 20 also includes a spring, which is connected to the first adjusting arm 24 and the second adjusting arm 25 respectively; when removing the boot, the spring force drives the first adjusting arm 24 and the second adjusting arm 25 to clamp and fix the two sides of the mining boot.

[0033] The shoe removal structure 20, by introducing a spring, further optimizes the functionality and user experience of the mining shoe remover. The connection design between the spring and the first adjusting arm 24 and the second adjusting arm 25 ensures that both sides of the shoe receive uniform and timely clamping force during the removal process, guaranteeing the shoe's stability in the slot 21 and preventing slippage or detachment. This dynamic clamping mechanism not only improves removal efficiency but also increases the adaptability of the entire device, allowing it to self-adjust according to different shoe sizes and shapes, ensuring a smooth removal process. The spring's elasticity ensures that the first adjusting arm 24 and the second adjusting arm 25 automatically return to the preset clamping state when no external force is applied, preparing for the next use and thus enhancing the automation level and convenience of the mining shoe remover. This design not only reduces manual adjustment steps but also achieves automatic adaptation of both sides of the shoe through the spring's self-adjusting function, enhancing the practicality and durability of the mining shoe remover and making it suitable for the fast and stable shoe removal needs of frontline coal mine workers.

[0034] Optionally, such as Figure 1 and Figure 3As shown, the first adjusting arm 24 and the second adjusting arm 25 are respectively hinged to the same position on the top of the support base 23, which is the hinge position 26. The first adjusting arm 24 and the second adjusting arm 25 form a scissor-like structure. The spring is connected to the end of the first adjusting arm 24 and the second adjusting arm 25 away from the opening 22, which is the connection position. The hinge position 26 is located between the opening 22 and the connection position.

[0035] The first adjusting arm 24 and the second adjusting arm 25 are connected by a hinge point 26, forming a scissor-like structure. This design allows the two arms to rotate on top of the support base 23, thereby adjusting the horizontal opening size of the opening 22. A spring is connected to the distal ends of the two adjusting arms. When the mining shoe is placed in the slot 21, the spring, through its elastic force, causes the first adjusting arm 24 and the second adjusting arm 25 to tightly clamp the sides of the mining shoe, ensuring the shoe is stable and does not easily slip during removal. The hinge point 26 is located between the opening 22 and the spring connection point. This arrangement ensures that when the mining shoe enters the slot 21, the opening 22 can automatically adjust to a suitable size according to the shoe width. Simultaneously, during removal, the spring effectively drives the two arms to clamp the mining shoe, achieving a labor-saving and stable removal action. Through this structural design, the mining shoe remover of this invention can adapt to mining shoes of different widths, providing good friction, reducing the physical exertion of miners when removing their shoes, and lowering the risk of slipping or falling during the removal process, effectively improving miners' safety and work efficiency.

[0036] like Figure 1 As shown, the boot removal structure 20 also includes a limiting member 27, which is disposed on the base 10 and is respectively limited and engaged with the ends of the first adjusting arm 24 and the second adjusting arm 25 away from the opening 22; the limiting member 27 is used to constrain the horizontal opening size of the opening 22.

[0037] The boot removal structure also includes a limiting member 27, which is mounted on the base 10. This limiting member 27 engages with the ends of the first adjusting arm 24 and the second adjusting arm 25 furthest from the opening 22, thus constraining the horizontal opening size of the opening 22. This design ensures stability and safety during the boot removal process. By controlling the adjusting arms through the limiting member 27, the size of the opening 22 can be adjusted to accommodate different sizes of mining boots, preventing the boot from becoming uncontrollable due to an excessively large opening during removal and avoiding unnecessary injury. The addition of the limiting member 27 also enhances the structural rigidity of the entire boot remover, ensuring the device remains stable even when bearing the weight of the miner and the forces generated during boot removal, preventing deformation or displacement. This improves the efficiency of the boot removal process and the miner's operating experience. The limiting member 27 also functions as part of the adjustment mechanism, allowing users to adjust the opening width according to their individual needs and the actual size of the mining boot. This personalized adjustment capability allows the boot remover to better serve coal miners and meet their diverse usage needs.

[0038] like Figure 1 and Figure 2 As shown, the first adjusting arm 24 and / or the second adjusting arm 25 have friction protrusions 28 on the inner wall facing the slot 21. When the shoe is removed, the friction protrusions 28 are used to abut against the side of the shoe to restrain the shoe; and / or, the cross-section of the first adjusting arm 24 and / or the second adjusting arm 25 in the vertical direction is trapezoidal, the upper and lower sides of the trapezoid are arranged in parallel, and the upper side dimension is larger than the lower side dimension.

[0039] Friction protrusions 28 are provided on the inner walls of the first adjusting arm 24 and the second adjusting arm 25 facing the slot 21. This design allows for close contact with the side of the mining shoe during shoe removal, providing additional frictional resistance, effectively securing the shoe, preventing slippage during removal, and enhancing the stability and reliability of the shoe remover. Simultaneously, the trapezoidal cross-section design of the first adjusting arm 24 and the second adjusting arm 25 in the vertical direction, with the upper dimension larger than the lower dimension, not only accommodates different sizes of mining shoe uppers but also provides a guiding effect when the shoe enters the slot 21, ensuring the shoe is securely clamped within the slot 21, further improving the efficiency and safety of shoe removal. The parallel arrangement of the upper and lower sides of the trapezoidal structure ensures that the shoe is not subjected to uneven pressure in the slot 21, preventing damage during removal and extending the shoe's service life. This design reflects a deep understanding of the actual needs of miners and the optimization of the structure and function of mining shoe removers, providing miners in coal mining environments with a safer, more efficient, and convenient shoe removal auxiliary tool.

[0040] Specifically, there are two boot removal structures 20, and the two boot removal structures 20 and a corresponding armrest structure form a matching group; wherein, within the same matching group, the horizontal distance between the two boot removal structures 20 corresponds to the average distance between a person's two feet.

[0041] Two boot-removing structures 20 are combined with a corresponding handrail structure to form a mating group. Within the same mating group, the horizontal distance between the two boot-removing structures 20 is set to match the average foot spacing of a human. This design allows miners to naturally place their feet between the two boot-removing structures 20 when removing their boots. Supported by the handrail structure, the miner can maintain balance, avoiding the risk of slipping and falling due to boot removal. The reasonable distance between the two boot-removing structures 20 not only provides comfortable space for the miner's feet but also ensures the stability of the mining boots during removal, improving efficiency and safety. Through the above design, the boot remover not only simplifies the boot removal process but also provides coal miners with a safer and more convenient working experience, reducing workplace accidents and lowering mine operating costs. In other embodiments not shown, the size and shape of the boot-removing structure 20 and the handrail structure can be further optimized to accommodate miners of different body types, enhancing the versatility and adaptability of the device.

[0042] Optionally, there are multiple mating groups, which are spaced apart; at least one of the base 10, armrest structure and boot removal structure 20 is made of steel or alloy material; the horizontal opening size of the opening 22 is not less than 4 cm.

[0043] The multiple interleaved groups optimize the overall user experience of the mining boot removal device, ensuring sufficient personal space for each miner, avoiding crowding and collisions, and enhancing safety. The use of steel or alloy materials as the main materials for the base 10, handrail structure, and boot removal structure 20 significantly improves the mechanical strength and durability of the entire device, enabling it to withstand the high-intensity loads of daily use by miners, while also adapting to the harsh, humid, and corrosive environment of underground coal mines, extending its service life. The horizontal opening of the opening 22 is set to be no less than 4 cm. This size selection is based on extensive analysis of mining boot dimensions, ensuring that the boot removal structure 20 is compatible with different models and sizes of mining boots, improving the device's versatility and applicability, and making the boot removal process smoother and more unobstructed. Through these meticulous considerations and designs, this setup not only simplifies the boot removal process and improves efficiency but also greatly protects miners' lives, reduces mine operating costs, and provides miners with a more convenient and safer post-work boot removal experience, contributing to improved overall mine efficiency and miner satisfaction.

[0044] Optionally, there are two boot removal structures 20, with two boot removal structures 20 and a corresponding armrest structure forming a matching group; within the same matching group, the armrest structure is located in the middle of the two boot removal structures 20; or, there are two boot removal structures 20 and two armrest structures, with two boot removal structures 20 and two corresponding armrest structures forming a matching group; within the same matching group, the two boot removal structures 20 are respectively located in the middle of the two armrest structures, and the horizontal distance between the two armrest structures corresponds to the average shoulder width of a human body.

[0045] The mining boot removal device is equipped with two sets of boot removal structures 20, each with a matching handrail structure, forming a cooperative working group. In particular, in the single-set configuration, the handrail structure is located in the center of the two boot removal structures 20, providing a stable support point for the miner, facilitating boot removal while standing on one foot, significantly enhancing balance and operational safety. In the double-set configuration, an additional pair of handrail structures is added, with the two pairs of boot removal structures 20 distributed on both sides of the handrail structure. The horizontal spacing of the handrail structure is precisely set to correspond to the miner's shoulder width, ensuring that the miner can maintain a comfortable standing posture when removing boots, while using the strength of the shoulders and arms to stabilize the body, preventing tipping during boot removal and reducing the risk of injury. This layout not only embodies the design concept of ergonomics, but also greatly improves the experience of miners removing their boots after high-intensity work, reduces physical exertion, and improves work efficiency. In addition, by reasonably adjusting the position and spacing of the handrail structure, the mining boot removal device can adapt to the needs of miners of different body types, demonstrating high versatility and applicability, and providing coal miners with a convenient and safe boot removal solution.

[0046] Specifically, the height of the handrail structure is adjustable; and / or the vertical height of the handrail structure is not less than 1.3m; and / or the mining boot remover also includes a bench for workers to sit on, so that workers can remove their boots in a seated position.

[0047] The height of the handrail structure is adjustable, a design that allows the mining boot remover to adapt to the needs of miners of different heights, ensuring that each user can remove their boots at the most comfortable height, improving the user experience and safety. And / or, the vertical height of the handrail structure is set at no less than 1.3 meters, ensuring that even when standing, miners can easily grasp the handrail to maintain balance, especially in environments of physical fatigue or slippery ground, this height setting is crucial for preventing slips and falls. And / or, the mining boot remover also includes a seat, allowing miners to remove their boots while seated, further reducing the risks associated with removing boots while standing, while also reducing physical exertion and improving ease of operation. The addition of the seat allows miners to remove heavy and secure mining boots under stable and safe conditions, significantly reducing workplace accidents and providing a more humane user experience. Through these improvements, the applicability, safety, and comfort of the mining boot remover have been comprehensively enhanced, providing substantial assistance to miners in personal protection and work efficiency improvements in harsh working environments.

[0048] The specific working process and principle of one embodiment of this utility model will now be described in detail as follows:

[0049] like Figure 1 and Figure 3 As shown, when coal miners take off their boots, they place them on... Figure 1 Within the slot 21, by holding onto the front handrail structure with both hands, keeping one foot still while lifting the other, the foot can easily be removed from the mining boot because the slot 21 secures the heel. Similarly, the other mining boot can be easily removed. Although the weight is still on one foot during the boot removal process, the miner's hands holding onto the front handrail structure effectively prevents slips, falls, and injuries caused by instability.

[0050] Through on-site investigation and analysis, it was found that workers habitually lift one foot while taking off their boots, which easily leads to slips, falls, and other safety accidents due to instability. A careful analysis of the mining boots revealed a protruding heel (see...). Figure 4 The protruding heel area has raised points that provide friction. When the mining shoe is placed in slot 21, it is locked in place, as... Figure 2 As shown, the vertical cross-section of the slot 21 is an inverted trapezoidal cross-section and has inverted teeth (i.e. friction protrusions 28), which can increase friction and prevent the fixed mining shoe from falling off.

[0051] like Figure 4 As shown, a physical lever principle mechanical analysis of the human foot structure is performed. In the figure, L1 and L2 represent torques, respectively. According to the torque equation and torque balance equation, we know that: M=FL, F1Sinα L1=F2Cosα According to mechanical analysis, when the groove 21 of the boot remover acts on the protruding heel of the mining boot, based on the lever torque balance principle, the longer L1 is, the less effort is required; when the included angle α equals 45°, F1 can be obtained. L1=F2 Since the sum of the torques is zero, when L1 is much greater than L2, we can conclude that F1 is much less than F2 (i.e., the force required to manually remove the boots). Therefore, we can conclude that using a boot remover is more labor-saving than removing the boots by hand.

[0052] The manufacturing process of base 10 is as follows: a 16mm thick steel plate is cut into lengths using electric welding. Width = 600mm A 400mm rectangle forms the base 10. The handrail structure is manufactured as follows: a 20mm diameter steel pipe is cut into two sections with lengths of 1200mm and 200mm using electric welding, and the base 10 and handrail structure are welded together using electric welding. The entire mining boot remover is then painted to prevent rusting. The mining boot remover proposed in this utility model can be manufactured using locally available materials, such as common materials from coal mines, chemical plants, and other relevant user units. It is convenient, practical, low-cost, safe, and efficient.

[0053] In summary, this utility model provides a mining boot removal device. By using a base 10, a handrail structure, and a boot removal structure 20 in conjunction, this utility model achieves fast and stable boot removal with a simple structure. The handrail structure allows workers to easily hold on while removing their boots. The adjustable horizontal opening size of the opening 22 makes this utility model applicable to various mining boots. It not only simplifies the boot removal process and improves efficiency but also significantly enhances safety. It solves the problem of difficult boot removal for frontline coal miners, eliminates slips and falls during the process, maximizes miner safety, reduces the probability of work-related injuries caused by slips and falls during boot removal, and lowers the operating costs of safe mine production. In actual underground use, it has been found that frontline coal miners experience significant improvements in boot removal efficiency. This invention significantly reduces safety accidents, minimizes economic losses and personal injuries caused by work-related injuries, reduces injuries to miners due to improper boot removal, and saves considerable time and energy. It has significant economic and social benefits in improving miner satisfaction, reducing work injury compensation, and creating a safer working environment. Furthermore, the mine boot removal device proposed in this invention is easy to manufacture and maintain, making it widely applicable in coal mines and similar industries, and contributing to raising labor protection standards across the entire industry. This invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of existing boot removal auxiliary tools that fail to adequately address the practical difficulties faced by coal miners when removing their boots, lack stability, have poor adaptability, and are inconvenient to use, making it suitable for large-scale promotion and use.

[0056] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0057] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0058] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0059] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
