Description

Technical Field

[0001] The present invention relates to the technical field of mining equipment, and particularly to a hydraulic-driven top-loading loading station used in a conveying system for mining. Background Art

[0002] In some mine engineering projects, generally, a load-haul-dump (LHD) vehicle or a continuous conveyor is used to transport ore mined from, for example, an underground mine to a stockyard or a chute inside or outside the mine, such as a mine shaft, and then the ore is loaded into a mining truck or a rail mine car at the stockyard or the chute for transportation. The ore discharging device is a side-loading vibrating ore discharger equipped with finger gates. The start and stop of the ore discharging motor are manually controlled to control the amplitude of the vibrating platen and control the material flow by controlling the opening and closing of the finger gates. This device needs to align with the vehicle before discharging each mine car, cannot meet the requirement of continuous loading, and has low operating efficiency. Due to the natural defects of the side-loading method, it is difficult for the material to be evenly distributed inside the mine car, which easily causes uneven loading of the mine car, resulting in large impacts and wear on the track and the unloading station. Moreover, since the side-loading method will cause excessive loading height, it is easy to spill materials and also easy to damage the facilities at the top of the roadway in, for example, an underground mine. Replacing the traditional electric side-loading vibrating ore discharger with a hydraulic-driven top-loading loading station will be an effective means to improve the mine transportation efficiency, enhance the mine safety performance, and reduce the infrastructure maintenance cost.

Thus, features defined with "first", "second", "third", "fourth" may explicitly or implicitly include one or more of such features.

[0027] Figure 1 It shows the schematic diagram of the structure of the top-loading loading station of the present invention, Figure 2This is a structural top view of the top-loading loading station of the present invention. The loading station includes an ore bin 1, a lip plate 2 matching the size of the ore truck, and a chain gate.

[0028] The top of the ore bin 1 has an ore inlet 14. The bottom surface area of the ore feed bin facing the inlet is an inclined plane. The ore bin 1 and the lip plate 2 are connected by a discharge lip plate pin shaft 11 at the bottom of the ore bin.

[0029] One end of the rotary connection shaft on the side of the lip plate close to the ore bin 1 is wider in size, the ore outlet part is smaller in size, and a narrowing transition area is provided in the middle. The side wall spacing of the wide part of the lip plate 2 matches the external size of the ore bin 1; the width of the lower part of the lip plate 2 (Lip) matches the size of the ore truck to prevent material leakage. The side of the lip plate close to the ore bin has a rotary connection part, and hydraulic drive connection components 9 are respectively arranged on the outer parts of the two side walls far from the ore bin.

[0030] Liners 10 are installed on the inner walls of the ore bin and the loading lip plate. The liner material is high-strength wear-resistant steel plate, and its thickness can be selected differently according to the installation position. For example, the thickness of the liner at the bottom and the side wall positions close to the bottom is 25 mm, and the thickness of the liner at the high position of the side wall is 16 mm. The liner 10 has a fixed hole structure 16, and a plurality of pneumatic hammer holes 15 are provided on the surfaces of the ore bin 1 and the lip plate 2 through the fixed holes 16 on the liner 10 to connect and fix the liner 10. By using the liner 10, the service life of the equipment can be significantly extended, and the liner does not need to be replaced frequently, improving safety.

[0031] The loading lip plate and the chain gate are driven by hydraulic cylinders. The loading station includes a first buffer hydraulic cylinder group 3 and a second buffer hydraulic cylinder group 4. Both the first and second buffer hydraulic cylinder groups include two buffer hydraulic cylinders. Among them, the first buffer hydraulic cylinder group 3 includes two buffer hydraulic cylinders with a stroke of 1400 mm and bellows, and the second buffer hydraulic cylinder group 4 includes two buffer hydraulic cylinders with a stroke of 500 mm and bellows.

[0032] Figure 3 This is the second view of the top-loading loading station of the present invention; Figure 4Schematic structural diagram of the top-loading loading station of the present invention along the A-A section in the second view. The loading station is supported and fixed by a set of ore discharge machine feet 13 at the bottom. After loading the ore material into the ore bin 1, the dumping of the ore material in the bin is controlled by the opening and closing of the chain gate in the ore bin. The chain gate includes an upper chain group 17, a heavy crossbar 7, a chain gate rocker arm 8, a chain gate connecting rod 12, a lower chain group 5 and steel balls 6. The top of the upper chain group 17 is connected and fixed to the top of the ore bin. The bottom end of the upper chain group 17 is connected to the heavy crossbar 7. The heavy crossbar 7 is connected to the top end of the lower chain group 5. The bottom end of the lower chain group 5 is connected to the steel balls 6. The steel balls 6 connected to the lower chain group are connected by a transverse chain to keep the lower chain group and the steel balls moving synchronously as a whole. The top end of the chain gate rocker arm 8 is connected to the top of the ore bin through a second rotating connection shaft 18. The bottom of the chain gate rocker arm 8 is connected to the heavy crossbar 7. When the chain gate rocker arm rotates around the second rotating connection shaft 18, it can drive the heavy crossbar 7 and the connected upper and lower chains and steel balls to move together. The upper chain group 17 and the lower chain group 5 are composed of wear-resistant forged steel chains with a diameter of 30 mm.

[0033] As Figure 4 shown, the lower ends of the buffer hydraulic cylinders of each first buffer hydraulic cylinder group 3 are connected to the hydraulic drive connection group 1 components 9 on both sides of the lip plate 2. The upper ends of the buffer hydraulic cylinders are connected as fixed ends to the fixed beam or other fixed points through a rotating connection shaft. By the extension and shortening of the first buffer hydraulic cylinder group 3, the lip plate 2 can be driven to rotate around the first ore discharge lip plate pin shaft 11 to be in the "deployed" and "retracted" states respectively. When the lip plate is deployed, its bottom surface is in the same plane as the inclined surface of the ore bin, which is very conducive to loading the ore material into the ore car compartment in the loading station.

[0034] The upper ends of each hydraulic cylinder of the second buffer hydraulic cylinder group 2 are also connected as fixed ends to the fixed beam or other fixed points through a rotating connection shaft. The lower end of the hydraulic cylinder is connected to the heavy crossbar connection component 8. By driving the heavy crossbar connection component 8 to rotate around the second rotating connection shaft 18 by the second buffer hydraulic cylinder group 2, when the second buffer hydraulic cylinder group 4 is in the extended and retracted states respectively, the chain gate is driven to be in the closed state and the open state.

[0035] The first buffer hydraulic cylinder group 3 and the second buffer hydraulic cylinder group 4 act synchronously in pairs by the hydraulic power of the hydraulic pump station. The hydraulic station adjusts the action speed through the flow control of the hydraulic oil and can extend the hydraulic cylinder group within 3 seconds.

[0036] Figure 5 Schematic diagram of the assembled state of the top-loading loading station of the present invention.

[0037] The top-mounted loading station adopts a bolted connection structure type, which is easy to disassemble, assemble, move, and relocate between different ore loading points. The complete set of loading station includes oil cylinders, pipelines, valves, a hydraulic pump station, and an operating console, as well as a frame and an inspection and maintenance platform made of steel structural parts. Stairs and handrails are provided on both sides behind the loading station for easy access to the platform. Ore rails pass through the platform of the loading station, and ore vehicles pass through the top-mounted loading station via the rails, load ore materials, and then move out of the loading station. The staff of the loading station can control it through the local operating console at the loading station or receive control signals sent by customers for remote control.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
