Description

Technical Field

[0001] The utility model relates to the field of mine skips, in particular to an improved mine hoisting skip. Background Art

[0002] Mine hoisting skips are key equipment used in mines to lift ore, waste rock and other materials. According to their use environment and functions, mine hoisting skips can be divided into two types: for inclined shafts and for vertical shafts. Vertical shaft skips are mainly used for vertical shaft hoisting, and can be divided into bottom unloading type and flip type according to different unloading methods. Bottom unloading skips open the bottom gate in the vertical shaft to unload materials into the coal bunker or unloading station at the bottom of the shaft; while flip skips pour materials out by flipping the skip.

[0003] The capacity of the vertical shaft skip is large to meet the lifting needs of a large amount of materials in the vertical shaft. In addition, the vertical shaft skip can be divided into single-rope skip and multi-rope skip. The single-rope skip uses one wire rope for hanging, with a simple structure, suitable for shallow wells and small mines; while the multi-rope skip uses multiple wire ropes for hanging, with good stability, suitable for deep wells and large mines.

[0004] The unloading process of the tipping skip depends on the action of the gate mechanism. The gate is a flat plate that can move vertically in the side wall guide rails of the tipping skip bucket, or a fan-shaped gate installed at the bottom of the bucket. When the gate is closed, it is part of the bucket and bears the lateral pressure of the coal in the bucket. The opening and closing of the gate are realized by the unloading device installed on the derrick.

[0005] However, the gate design may have gaps during the unloading process, causing material leakage. For externally powered vertical flat gate skips, if the seal between the gate and the bucket box is not tight, or if it is worn out during long-term use, a gap will be created during unloading, causing material to leak from the gap. Similarly, for externally powered bottom fan gate flip skips, if the seal between the fan gate and the bottom of the bucket box is not tight, or if it is worn out during long-term use, it will also cause material to leak from the gap during unloading.

[0006] Therefore, when designing and using mine hoisting skips, it is necessary to fully consider their unloading methods, structural characteristics and sealing performance to ensure safe and efficient lifting of materials. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 4 As shown, an improved mine hoisting skip comprises a hoisting frame 1, a connecting frame 2, a discharge port 3, a connecting piece 4 and a hopper 5. The discharge port 3 is installed on the upper part of the side wall of the hoisting frame 1 through the connecting frame 2, and the hopper 5 is fixed inside the hoisting frame 1 through the connecting piece 4. A movable plate 7 is provided at the bottom of the inner cavity of the hopper 5, and a bottom cavity 6 is connected to the lower end of the movable plate 7, and is connected to an electric push rod 8 through a connector 9. The electric push rod 8 is then connected to the hopper 5 through a U-shaped bracket 10. When the electric push rod 8 is extended and retracted, it can drive the movable plate 7 to move up and down in the hopper 5, thereby realizing the transportation of materials;

[0025] The upper edge of the movable plate 7 is also connected to an arc strip 11, and an elastic discharge plate 12 is provided at the upper end of the arc strip 11. The elastic discharge plate 12 can be driven by the electric push rod 8 to pass through the connecting frame 2 and rest on the discharge port 3. When the movable plate 7 moves up and down, the elastic discharge plate 12 will also move accordingly, thereby realizing the rapid discharge of materials; the connecting piece 4 is fixed to the hopper 5 by welding, and the upper end of the hopper 5 is designed to be an inclined surface so as to better cooperate with the discharge port 3 and the connecting frame 2 to realize rapid discharge. At the same time, the contact end of the movable plate 7 and the hopper 5 is designed to be smooth to reduce friction, and the arc corner of the movable plate 7 is adapted to the arc corner of the hopper 5 to ensure its smooth movement; the cross section of the U-shaped bracket 10 is designed in a "U" shape, and its upper end limits the falling range of the movable plate 7. The U-shaped bracket 10 is fixed to the electric push rod 8 by bolts, and the electric push rod 8 is connected to the connector 9 by threads. The connector 9 is then fixed to the lower end of the movable plate 7 by bolts, thereby ensuring the stability and reliability of the entire structure.

[0026] The arc strip 11 is fixed to the upper edge of the movable plate 7 by bolts. It is located at the discharge port of the hopper 5 and is used to support the elastic discharge plate 12. The elastic discharge plate 12 is fixed to the arc strip 11 by welding. It is made of elastic wear-resistant metal material and has certain elasticity and wear resistance. When the electric push rod 8 is extended, the elastic discharge plate 12 will deform and rest on the discharge port 3, thereby realizing the rapid discharge of materials; the improved mine hoisting bucket realizes rapid and efficient material transportation and discharge by optimizing the structural design and adopting advanced driving methods, thereby improving the production efficiency and economic benefits of the mine.

[0027] Working process: In the working process of this improved mine hoisting skip, the electric push rod 8, the movable plate 7 and the elastic discharge plate 12 work together to realize the rapid and efficient transportation and discharge of materials; the electric push rod 8 is driven by electricity, and when the material needs to be transported, the electric push rod 8 begins to extend and retract. When the electric push rod 8 is extended, it pulls the movable plate 7 upward through the connector 9; when the electric push rod 8 is retracted, the movable plate 7 moves downward under the action of gravity. The telescopic action of the electric push rod 8 is connected to the hopper 5 through the U-shaped bracket 10 to ensure stability and reliability; the movable plate 7 is located at the bottom of the inner cavity of the hopper 5, and is driven by the electric push rod 8 to move up and down in the hopper 5. When the movable plate 7 moves upward, the material in the hopper 5 is pushed to the vicinity of the discharge port 3; when the movable plate 7 moves downward, new materials enter the hopper 5 from above, ready for the next transportation. The contact end of the movable plate 7 and the hopper 5 is designed to be smooth, which reduces friction. At the same time, the arc corner is adapted to the arc corner of the hopper 5, ensuring the smooth movement of the movable plate 7; the elastic discharge plate 12 is connected to the movable plate 7 through the arc strip 11. When the electric push rod 8 is extended and the movable plate 7 moves upward, the elastic discharge plate 12 is deformed and rests on the discharge port 3. At this time, the material in the hopper 5 is quickly discharged to the outside through the elastic discharge plate 12 under the action of gravity. Since the elastic discharge plate 12 is made of elastic wear-resistant metal material, it has certain elasticity and wear resistance, so it can adapt to different materials and discharge requirements; the electric push rod 8, the movable plate 7 and the elastic discharge plate 12 work together to achieve fast and efficient transportation and discharge of materials. This improved mine hoisting bucket improves the production efficiency and economic benefits of the mine by optimizing the structural design and adopting advanced driving methods.
