Description

Technical Field

[0001] This application belongs to the field of mine steel support technology, specifically a mine steel support device. Background Technology

[0002] Mine steel support systems are key equipment for ensuring mine operation safety. They can construct a stable support system within the mine, effectively resist the pressure of the surrounding rock, prevent collapse accidents, create a safe working space for miners, and ensure the safe and smooth conduct of underground activities such as coal mining.

[0003] However, common mine steel support devices often lack lateral support structures due to the complex and varied rock pressures in mine roadways. The steel supports rely primarily on their own structure and top support to resist pressure. When subjected to significant lateral pressure, the supports are prone to tilting, twisting, or even collapsing, which can threaten mine safety. Utility Model Content

[0004] The purpose of this application is to provide a mine steel support device in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: a steel support device for mines includes a base, with fixing grooves on both sides of the base, an air pump fixedly connected to one side of the fixing groove, a main telescopic column provided at one end of the air pump relative to the fixing groove, a secondary telescopic column provided at one end of the main telescopic column relative to the air pump, and a pressure plate fixedly connected at one end of the secondary telescopic column relative to the main telescopic column.

[0006] By adopting the above technical solution, during use, an air pump can provide power to the auxiliary telescopic column. Driven by the auxiliary telescopic column, the pressure plate can be pressed against the mine wall, thereby fixing the overall structure. The surrounding rock pressure in mine roadways is complex, coming not only from the top but also from the sides. The added side support structure can effectively disperse and resist the pressure from the sides, preventing the support from tilting, twisting, or collapsing due to excessive lateral pressure. This enhances the stability of the entire steel support device, ensuring its reliable operation in the complex environment of the mine. The side support structure also shares some of the pressure originally borne by the main support structure, allowing the support to withstand a greater total load; it can effectively increase the mining depth and safety of the mine, ensuring the smooth extraction of resources such as coal.

[0007] In a preferred embodiment, the lower end of the base is rotatably connected to a plurality of rotating columns, and one end of each rotating column relative to the base is provided with a caster wheel.

[0008] By adopting the above technical solution, the rotating column connects the base and the casters, ensuring the stability and integrity of the overall structure and serving as a crucial component. The casters, mounted at the bottom of the support frame, offer 360-degree rotation, allowing the support frame to move freely within the mine and improving transportation and installation efficiency.

[0009] In a preferred embodiment, a plurality of connecting posts are fixedly connected to one side of the base, and a handle is fixedly connected to one end of the connecting posts relative to the base.

[0010] By adopting the above technical solution, the connecting column connects the base and the handle, ensuring the stability of the overall structure. The handle provides the operator with a grip and leverage point, facilitating the movement of the support and improving work convenience.

[0011] In a preferred embodiment, a handle glove is provided on the outer surface of the handle.

[0012] By adopting the above technical solution, gloves are put on the handles to increase friction, prevent operators from slipping their hands during operation, and improve the comfort and safety of operation.

[0013] In a preferred embodiment, a motor is provided on the upper surface of the base, and a main column is provided at the center of one end of the motor relative to the rotating column.

[0014] By adopting the above technical solution, the motor serves as the power source, providing power for the lifting, moving, and other actions of the support. Driven by the motor, the height and position of the support can be adjusted, effectively reducing the burden on manpower. The main column is the primary load-bearing component of the support, bearing most of the pressure from the shield beam and transferring it to the base. This ensures that the support can stably support the roof, guaranteeing mine safety.

[0015] In a preferred embodiment, the motor is provided with a plurality of auxiliary columns at one end relative to the rotating column.

[0016] By adopting the above technical solution, the secondary column assists the main column in providing support, enhancing the overall load-bearing capacity of the support system. The secondary column can share some of the pressure and work in coordination with the main column to improve the stability and reliability of the support system.

[0017] In a preferred embodiment, a protective beam is provided at one end of the auxiliary column relative to the motor, and multiple column legs are fixedly connected to the upper surface of the protective beam.

[0018] By adopting the above technical solution, the shield beam plays a protective role, blocking falling rocks from the roof and preventing them from injuring equipment and personnel below. The column legs connect the shield beam and the top beam, serving to support and stabilize the support structure.

[0019] In a preferred embodiment, the column leg is fixedly connected to a top beam at one end relative to the shield beam.

[0020] By adopting the above technical solution, the top beam is in direct contact with the mine roof, which can evenly distribute the pressure to the main and auxiliary columns, ensuring the stability of the support and providing effective support.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0022] In this application, during use, an air pump can provide power to the auxiliary telescopic column. Driven by the auxiliary telescopic column, the pressure plate can be pressed against the mine wall, thereby fixing the overall structure. The surrounding rock pressure in mine roadways is complex, originating not only from the top but also from the sides. The added side support structure can effectively disperse and resist the pressure from the sides, preventing the support from tilting, twisting, or collapsing due to excessive lateral pressure. This enhances the stability of the entire steel support device, ensuring its reliable operation in the complex environment of the mine. The side support structure shares some of the pressure originally borne by the main support structure, allowing the support to withstand a greater total load; it can effectively increase the mining depth and safety of the mine, ensuring the smooth extraction of resources such as coal.

A main telescopic column 4 is installed at one end of the air pump 3 relative to the fixing slot 2, and a secondary telescopic column 5 is installed at the other end of the main telescopic column 4 relative to the air pump 3. A pressure plate 6 is fixedly connected to the other end of the secondary telescopic column 5 relative to the main telescopic column 4. In use, the air pump 3 provides power to the secondary telescopic column 5, which, through its movement, pushes the pressure plate 6 against the mine wall, thus fixing the overall structure. The surrounding rock pressure in mine roadways is complex, coming not only from the top but also from the sides. The added side support structure effectively disperses and resists the pressure from the sides, preventing the support from tilting, twisting, or collapsing due to excessive lateral pressure. This enhances the stability of the entire steel support device, ensuring its reliable operation in the complex mine environment. The side support structure also shares some of the pressure originally borne by the main support body, allowing the support to withstand a greater total load; it effectively increases the mining depth and safety of the mine, ensuring the smooth extraction of resources such as coal.

[0031] Reference Figure 3 The lower end of the base 1 is rotatably connected to multiple rotating columns 7, and one end of each rotating column 7 is equipped with a caster wheel 8 relative to the base 1. The rotating columns 7 connect the base 1 and the caster wheels 8, ensuring the stability and integrity of the overall structure and are an important component of the overall structure. The caster wheels 8 are installed at the bottom of the support and have the characteristic of 360-degree rotation, allowing the support to move freely in the mine and improving the transportation and installation efficiency of the support.

[0032] Reference Figure 3 Multiple connecting posts 9 are fixedly connected to one side of the base 1, and a handle 10 is fixedly connected to one end of each connecting post 9 relative to the base 1. The connecting posts 9 connect the base 1 and the handle 10, ensuring the stability of the overall structure. The handle 10 provides the operator with a grip and force application point, making it convenient to move the support and improving the ease of operation.

[0033] Reference Figure 3A glove 11 is provided on the outer surface of the handle 10. The glove 11 is put on the handle 10 to increase friction, prevent the operator's hand from slipping during operation, and improve the comfort and safety of operation.

[0034] Reference Figure 1 , Figure 4 A motor 12 is mounted on the upper surface of the base 1, and a main column 13 is positioned at the center of one end of the motor 12 relative to the rotating column 7. The motor 12 serves as a power source, providing power for the lifting, lowering, and moving of the support. Driven by the operation of the motor 12, the height and position of the support can be adjusted, effectively reducing the burden on manpower. The main column 13 is the main load-bearing component of the support, bearing most of the pressure from the shield beam 15 and transferring the pressure from the shield beam 15 to the base 1. This ensures that the support can stably support the roof, guaranteeing the safety of the mine.

[0035] Reference Figure 4 The motor 12 has multiple auxiliary columns 14 at one end relative to the rotating column 7. The auxiliary columns 14 assist the main column 13 in providing support, enhancing the overall load-bearing capacity of the support. The auxiliary columns 14 can share some of the pressure and work together with the main column 13 to improve the stability and reliability of the support.

Multiple column legs 16 are fixedly connected to the upper surface of the protective beam 15. The protective beam 15 serves to shield and protect the equipment, preventing falling rocks from the top plate from injuring the equipment and personnel below. The column legs 16 connect the protective beam 15 and the top beam 17, serving to support and stabilize the support structure.

[0037] Reference Figure 4 One end of the column leg 16 is fixedly connected to the top beam 17 relative to the shield beam 15. The top beam 17 is in direct contact with the mine roof, which can evenly distribute the pressure to the main column 13 and the auxiliary column 14, ensuring the stability of the support and providing effective support.

[0038] The implementation principle of an embodiment of a mine steel support device according to this application is as follows:

[0039] In use, the auxiliary telescopic column 5 is powered by the air pump 3. Driven by the auxiliary telescopic column 5, the pressure plate 6 is pressed against the mine wall, thus fixing the entire structure. The surrounding rock pressure in mine roadways is complex, originating not only from the top but also from the sides. The added side support structure effectively disperses and resists the pressure from the sides, preventing the support from tilting, twisting, or collapsing due to excessive lateral pressure. This enhances the stability of the entire steel support device, ensuring its reliable operation in the complex mine environment. The side support structure also shares some of the pressure originally borne by the main support structure, allowing the support to withstand a greater total load; it effectively increases the mining depth and safety of the mine, ensuring the smooth extraction of resources such as coal.
