[0027] See also Figure 1 , Figure 2 as well as Figure 3 A mine incline is a vertical or inclined passage used in the mining process for miners to enter and exit the mine or to transport ore and other materials. Miners often descend into the incline by stairs. These stairs are usually made of metal or wood and are installed at regular intervals along the walls of the incline to facilitate climbing when miners enter and exit the incline.
[0028] However, in the process of exiting the inclined shaft, miners have to work hard to climb these stairs. Due to the large inclination of the mine, the number of stairs is also correspondingly large, which makes climbing more laborious. Based on this, the present application provides a walking power tool 2 for mine personnel, including a support assembly 1 arranged in the tunnel, the support assembly 1 includes a steel cable 13 and a bracket 11, the steel cable 13 is located on the outside of the bracket 11, and a guide wheel 12 is arranged on the outside of the bracket 11. A fixing member 14 connected to the bracket 11 is also arranged on one side of the guide wheel 12 for guiding and supporting the steel cable 13;
[0029] The outer side of the steel cable 13 is adapted with a power-assisting tool 2 for assisting pedestrians in walking;
[0030] The power assist tool 2 includes a card frame 21 adapted to the steel cable 13, a connecting hole 23 is provided above the card frame 21, a connecting knot 22 is installed at the connecting hole 23, and a handle 3 is inserted on one side of the connecting knot 22 for assisting pedestrians in walking.
[0031] The outer side of the steel cable 13 is adapted with a power assist component for providing walking assistance to pedestrians. The power assist component is composed of a card frame 21 adapted to the steel cable 13, and a connection hole 23 is provided above the card frame 21, and a connection knot 22 is installed at the connection hole 23. A handle 3 is inserted on one side of the connection knot 22 for pedestrians to assist walking.
[0032] When using the power-assisting tool 2, a pedestrian can hold the handle 3 and apply force to make the power-assisting component engage with the steel cable 13. In this way, when the pedestrian walks, the power-assisting component will be pulled by the steel cable 13, and through the support of the guide wheel 12 and the guidance of the fixing member 14, it helps the pedestrian to walk smoothly. The engaging design of the power-assisting component enables the user to pass the stairs of the inclined shaft more easily, reducing the burden and fatigue of walking.
[0033] Combined with the above description, the power-assist tool 2 for walking of mine personnel provides an effective way for miners to walk easily in the mine inclined shaft. Through the support of the steel cable 13 and the bracket 11, plus the clamping design of the power-assist component, the tool can assist the walking of pedestrians, thereby improving work efficiency and safety.
[0034] The connection knot 22 is an important part of the power assist assembly, which is located at the connection hole 23 of the power assist assembly and plays the role of connecting the handle 3 and the power assist assembly. The connection knot 22 is generally a solid metal component, with a design suitable for the handle 3 to be inserted and firmly fixed.
[0035] A handle 3 is inserted on one side of the connection knot 22, which is usually a handle-shaped component. It can be designed according to the hand shape and habits of the user to provide a comfortable holding experience. The handle 3 may be made of non-slip material or textured to increase stability and comfort when holding. In addition, the shape and size of the handle 3 should also conform to ergonomic principles to ensure that hand fatigue and discomfort are reduced during long-term use.
[0036] The connection knot 22 needs to ensure a firm connection between the handle 3 and the power-assisting assembly while coordinating with the power-assisting assembly. Generally, the design of the connection knot 22 takes into account stability and detachability. For example, the connection knot 22 may use a thread or a locking device to ensure a firm connection between the handle 3 and the power-assisting assembly to avoid loosening or falling off during use. Such a design can ensure the stability and safety of the handle 3 while facilitating replacement or maintenance.
[0037] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 A groove adapted to the steel cable 13 is provided at the bottom of the card frame 21, the groove is arranged in a preset arc, and one or more connecting strips 27 are arranged in a ring array on the inner side of the groove.
[0038] One side of the connecting strip 27 is provided with one or more fixing flanges 25 arranged in a linear array, and balls are clamped at the fixing flanges 25 , and the balls are in contact with the outer side of the steel cable 13 .
[0039] The clamping frame 21 is one of the key components of the power assist assembly, which is located at the bottom of the power assist assembly and has grooves adapted to the steel cable 13. These grooves present a preset arc setting, which is intended to match the shape of the steel cable 13 to ensure the effective clamping of the power assist assembly and the steel cable 13.
[0040] The inner side of the groove is designed as an annular array and is installed with one or more connecting strips 27. The connecting strips 27 are solid components connected to the card frame 21, and they play the role of connecting the groove and other parts of the power assist assembly. One side of the connecting strip 27 has one or more fixed flanges 25 arranged in a linear array, and the positions of these fixed flanges 25 correspond to the annular array inside the groove. The fixed flanges 25 are connected to the ball bearings by snapping or other means, and the ball bearings are in contact with the outer side of the steel cable 13.
[0041] When in use, the power assist assembly forms a close connection with the steel cable 13 by clamping the groove with the steel cable 13. The design of the fixing flange 25 and the ball of the connecting strip 27 enables the ball to keep in contact with the outside of the steel cable 13 and provide necessary friction during walking. In this way, when the user applies forward force, the power assist assembly can directly pull the steel cable 13 through the ball to provide walking assistance.
[0042] Through this design, the power assist assembly can effectively utilize the power of the steel cable 13 to provide additional power assist for the miners to walk. The design of the connecting strip 27 and the fixing flange 25 enables the power assist assembly to be tightly and firmly connected to the steel cable 13, ensuring the reliability and safety of the walking assist. At the same time, the movement of the ball and the contact with the steel cable 13 help to reduce the friction resistance during walking, making the walking process smoother and easier.
[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 A card connection area 28 is provided at the groove of the card frame 21, and the card connection area 28 is provided in an open shape. A group of symmetrically arranged installation cavities 26 are provided near the bottom of the inner wall of the card frame 21, and a contact piece is provided at the installation cavity 26, which contacts the outer side of the steel cable 13.
[0044] A completely penetrating inspection opening 24 is provided on one side of the card frame 21 , and the inspection opening 24 is adapted to the connecting knot 22 .
[0045] The groove of the card frame 21 is provided with a card connection area 28, which is designed in an open shape to ensure reliable card connection between the power assist component and the steel cable 13. Such an opening design can conveniently place the power assist component on the steel cable 13, and also facilitates disassembly and maintenance.
[0046] A group of symmetrically arranged mounting cavities 26 are also provided at the bottom of the card frame 21 near the inner wall. These mounting cavities 26 are used to install corresponding contact members, which keep in contact with the outer side of the steel cable 13 and provide support. Through the symmetrical arrangement of the mounting cavities 26, the force distribution of the contact members is uniform, thereby ensuring the contact force balance between the power assist assembly and the steel cable 13.
[0047] A completely through inspection port 24 is provided on one side of the card frame 21, and the inspection port 24 is adapted to the connection knot 22. The design of the inspection port 24 allows the user to conveniently inspect and maintain the power assist assembly and the connection knot 22. The existence of the inspection port 24 can help improve the maintainability and reliability of the power assist tool 2, so that the user can promptly discover and deal with potential problems.
[0048] Through such a design, the clamping area 28 between the power assist assembly and the steel cable 13 can be easily and quickly installed and removed. The establishment of the contact piece ensures close contact between the power assist assembly and the steel cable 13, providing stable and uniform walking assistance. At the same time, the adaptation of the inspection port 24 provides a convenient means of inspection and maintenance, ensuring the long-term stable operation of the power assist tool 2.
[0049] The contact piece is an important component installed in the mounting cavity 26 of the card frame 21. Its function is to keep in contact with the outside of the steel cable 13 to provide stable support and walking assistance. The contact piece is usually made of a solid material, such as metal or wear-resistant material, to ensure that it has sufficient strength and durability.
[0050] The design of the contact piece should consider the contact area and shape with the outside of the steel cable 13 to provide the best friction and stability. A common design is to make the contact piece into a ring or semi-ring shape to match the curve shape of the outside of the steel cable 13. Such a design can ensure that the contact points between the contact piece and the outside of the steel cable 13 are evenly distributed, and increase the contact area, providing better friction and walking assistance.
[0051] In order to increase the friction between the contact piece and the steel cable 13, the surface of the contact piece is usually specially treated, such as adding textures, grooves or coatings. These treatments can increase the friction coefficient of the contact piece and provide a more secure contact to prevent slipping and loss of control. In addition, the surface of the contact piece should also be wear-resistant to ensure stability and durability during long-term use.
[0052] In order to facilitate adjustment and maintenance, the contact piece can usually be flexibly installed in the installation cavity 26 of the card frame 21. These installation cavities 26 can be adjusted as needed to ensure that the contact force between the contact piece and the steel cable 13 is appropriate and evenly distributed. At the same time, this adjustable design also facilitates the replacement and maintenance of the contact piece, reducing the interference of the maintenance process on the power assist component.
[0053] Through such a contact design, the power assist assembly can effectively utilize the power of the steel cable 13 to provide stable and reliable walking assistance. The shape and special treatment of the contact ensure close contact with the outside of the steel cable 13, providing sufficient friction to support the power transmission and stability during walking. Such a design can improve work efficiency, reduce walking resistance, and increase walking comfort and safety.
[0054] For example, a metal plate of the same material as the steel cable 13 is used, one end of which is provided with a spring, which is installed inside the installation cavity 26 through the spring. When combined with the steel cable 13, the spring is compressed and deformed to provide a resisting force. Due to the above-mentioned use of the ball bearing, it will not cause an impact when sliding, and when connected with the steel cable 13, the card frame 21 can be kept stable;
[0055] The handle 3 includes a connecting rod 31, one end of which is connected to the connecting knot 22, and a non-slip rubber sleeve 32 is sleeved on the rod body of the connecting rod 31 to increase friction for pedestrians to hold.
[0056] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
