[0002] At present, coal-fired power plants and cement plants mostly use inclined belt conveyors for vertical material transportation. This type of inclined belt conveyor needs to be set up on the civil construction trestle corridor and transport materials in stages. Transfer stations need to be configured at the transfer points of each level of belt conveyors for transfer. Therefore, the use of inclined belt conveyors to transport materials has the disadvantages of occupying a large land area, high infrastructure costs, and high equipment investment. At the same time, materials are prone to generate dust during transportation and transfer, causing dust pollution to the surrounding environment.

[0003] In addition, bucket type vertical elevators are commonly used to transport powdery, granular and small block materials from low places to high places. They have simple structures, small footprints, and closed transportation with little environmental pollution. However, for ultra-high bucket type vertical elevators with a lifting height of 60m to 80m, the maintenance of chain buckets is difficult, especially for large ultra-high chain bucket vertical elevators. The chains and chain buckets are relatively large, and it is difficult to replace the chain buckets from the bottom or top of the vertical elevator and arrange the tensioning device.

[0046] Figure 7 FIG. 2 is a schematic diagram of the installation of a first sprocket 2000 and a transition sprocket 9000 according to an embodiment of the present application, as shown in FIG. Figure 7 As shown, this schematic diagram is a partial right view of the vertical hoist 1.

[0047] In some embodiments of the present application, Figure 1 , Figure 2 and Figure 7 As shown, the first sprocket 2000 is disposed at the top of the frame 1000 and is provided with a top cover 10100; the second sprocket 3000 is disposed at the bottom of the frame 1000. The first sprocket 2000 and / or the second sprocket 3000 are used to receive the lifting driving force. Figure 7 As shown, when the first sprocket 2000 is arranged at the top of the frame 1000, the lifting driving force is provided by the lifting driving unit 19000 fixed on the top of the frame 1000. According to the number of chains 4000 and the connection mode of the chains 4000 and the chain bucket 5000, the first sprocket 2000 and the second sprocket 2000 are symmetrically arranged. For example, Figure 7 As shown, two chains 4000 fix the chain bucket 5000 and are arranged on both sides of the chain bucket 5000. At this time, two first sprocket wheels 2000 are symmetrically arranged according to the distance between the chains 5000.

[0048] In some embodiments of the present application, Figure 7 As shown, the bearing seat of the first sprocket 2000 is provided with a bearing seat temperature rise detection device 17000 and a hoist braking device 18000, wherein the bearing seat temperature rise detection device 17000 is convenient for real-time detection of temperature changes inside the bearing seat, and provides an alarm signal when the temperature change exceeds the design value to avoid fire caused by excessive temperature.

[0049] In some embodiments of the present application, Figure 2As shown, the second sprocket 3000 is at the bottom of the frame 1000, and a feed chute 12000 is provided on the side of the frame 1000, and the chain bucket 5000 receives materials from the feed chute 12000. In addition, a material blocking plate 13000 is provided at the discharge port of the feed chute 12000, and the material blocking plate 13000 is used to guide the accumulation position of the material input from the feed chute 12000 to prevent the chain bucket 5000 from being stuck, so as to facilitate digging and lifting of materials.

[0050] like Figure 1 and Figure 2 As shown, the chain bucket 5000 moves up and down along with the chain 4000 , and the direction and height of the bucket mouth of the chain bucket 5000 are changed by the first sprocket 2000 and the second sprocket 3000 , so as to realize the excavation, lifting and dumping of materials.

[0051] In some embodiments of the present application, the vertical hoist 1 further includes a chain bucket deformation detection device 16000, which is disposed on the inner wall of the frame cover 10200 on the side of the frame 1000. When the deformation of the chain bucket 5000 exceeds a preset value, the chain bucket deformation detection device 16000 sends an alarm signal.

[0052] In some embodiments of the present application, Figure 7 As shown, the chain 4000 of the vertical hoist 1 adopts two sleeve roller chains, and the chain bucket 5000 is fixed between the two chains 4000, so that the chain bucket 5000 has higher stability, the capacity of the chain bucket 5000 can be increased, and the lifting efficiency of the material is improved. Figure 1 and Figure 2 As shown, the chain bucket 4000 circulates in the vertical direction within the closed frame 1000 structure formed by the cover shell 10000 and transports materials.

[0053] In some embodiments of the present application, Figure 2 As shown, a plurality of pairs of chain guide blocks 15000 are arranged in the movement direction of the chain 4000 and the chain bucket 5000. The chain guide blocks 15000 are arranged on the inner wall of the web bar 1200 of the frame 1000 to support and guide the chain 4000, reduce the friction of the chain 4000, reduce the noise, and extend the service life of the chain 4000.

[0054] Figure 4 for Figure 2 A partial enlarged view of the middle A area; Figure 5 For along Figure 4 Cross-sectional view of section BB.

[0055] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the tensioning device 6000 pulls the chain 4000 horizontally to tension the chain 4000. Figure 2 , Figure 4 and Figure 5 As shown, the tensioning device 6000 is hinged to the protruding part in the middle of the frame 1000, and the middle A part of the frame 1000 is installed on the civil structure 3, so that the ultra-high vertical hoist 1 is more stable, easier to tension, convenient to adjust the tensioning device 6000, and convenient to repair the chain 4000, the chain bucket 5000, the tensioning device 6000 and other equipment.

[0056] In some embodiments of the present application, Figure 4 As shown, the tensioning device 6000 includes a tensioning adjustment structure 6100, a tensioning sprocket 6200, a tensioning sprocket bearing seat 6300, and a tensioning sprocket shaft 6400. The tensioning sprocket 6200 is disposed on the tensioning sprocket shaft 6400, and the tensioning sprocket shaft 6400 and the tensioning sprocket bearing seat 6300 are fixedly or rotatably connected. The tensioning sprocket 6200 abuts against the inner side of the chain 4000.

[0057] In some embodiments of the present application, Figure 5 As shown, the tensioning sprocket bearing seat 6300 is slidably connected to the frame 1000 via a guide assembly 6600. For example, the tensioning sprocket bearing seat 6300 is slidably connected to the frame 1000 via a guide groove 6620 provided on the tensioning sprocket bearing seat 6300 and a guide rail 6610 on the frame. The tensioning sprocket rotating shaft 6400 connects the tensioning sprocket 6200 and the tensioning sprocket bearing seat 6300.

[0058] In some embodiments of the present application, Figure 4 As shown, the tension adjustment structure 6100 is disposed on the frame 1000. The driving end of the tension adjustment structure 6100 is connected to the tension sprocket bearing seat 6300 to drive the tension sprocket 6200 to move. The tension sprocket bearing 6500 is connected to the tension sprocket bearing seat 6300 and the tension sprocket shaft 6400, so that the tension sprocket shaft 6400 and the tension sprocket bearing seat 6300 are rotatably connected.

[0059] In some embodiments of the present application, the tensioning device 6000 can also achieve the effect of tensioning the chain 4000 by pulling the chain 4000 in other directions. For example, the tensioning adjustment structure 6100 is fixed obliquely upward on the frame 1000, and the tensioning sprocket bearing seat 6300 is connected to the obliquely upward belly rod 1200 in the frame 1000, which can also achieve the purpose of increasing the transportation track of the chain 4000 to tension the chain 4000.

[0060] In some embodiments of the present application, the non-driving end of the tension adjustment structure 6100 is disposed on the frame 1000, and the distance between the driving end and the non-driving end of the tension adjustment structure 6100 is adjustable. When the distance between one end and the other end of the tension adjustment structure 6100 increases, the function of the tension chain 4000 can be achieved. The tension adjustment structure 6100 can adopt other devices that can move the position of the tension sprocket 6200.

[0061] In some embodiments of the present application, in order to reduce the resistance during the traction process, the tensioning sprocket 6200 can be a smooth cylindrical sleeve.

[0062] It is understandable that the present application does not impose any specific restrictions on the sliding connection between the tension sprocket bearing seat 6300 and the frame 1000, and any structure that can achieve the sliding connection between the tension sprocket bearing seat 6300 and the frame 1000 is within the protection scope of the present application. At the same time, the specific structure of the guide assembly 6600 between the tension sprocket bearing seat 6300 and the frame 1000 is also not specifically restricted, and any structure that can limit the sliding direction of the tension sprocket bearing seat 6300 and the frame 1000 is within the protection scope of the present application.

[0063] For example, the guide assembly 6600 may further include a guide groove and a roller disposed between the tensioning sprocket bearing seat 6300 and the frame 1000 .

[0064] In order to improve the stability during operation, in some embodiments of the present application, such as Figure 4 and Figure 5 As shown, when the chain 4000 adopts the above-mentioned two sleeve roller chains, two symmetrically arranged tensioning sprockets 6200 are set on the same tensioning sprocket rotating shaft 6400. When two tensioning oil cylinders are adopted as the tensioning adjustment structure 6100, the tensioning adjustment structure 6100 is a tensioning oil cylinder, and the oil cylinder 6110 of the tensioning adjustment structure 6100 is hinged to the frame 1000, and the pull rod 6120 of the tensioning adjustment structure 6100 is hinged to the tensioning sprocket bearing seat 6300. The tensioning sprocket bearing seat 6300 and the tensioning sprocket 6200 can slide on the guide rail 6610 through the extension and contraction of the two tensioning oil cylinders.

[0065] In some embodiments of the present application, Figure 2 , Figure 4 and Figure 5 As shown, a detachable middle cover 10300 is provided at the middle end of the frame 1000, and a detachable top cover 10100 is provided at the top end of the frame 1000. The vertical hoist 1 is convenient for repairing and maintaining the chain 4000 and the chain bucket 5000 by providing the top cover 10100 and the middle cover 10300.

[0066] When the tensioning device 6000 of the vertical hoist 1 adopts a tensioning cylinder, it can meet the tensioning chain 4000 requirement of the ultra-high chain bucket vertical hoist 1 with a lifting height of 60m to 80m (i.e., it can meet the requirement of 1 to 2% of the length of the tensioning chain 4000).

[0067] In some embodiments of the present application, Figure 1 and Figure 2 As shown, guide sprockets 8000 are arranged on both sides of the middle part of the frame 1000 to change the motion trajectory of the chain 4000 and the chain bucket 5000, so that the motion trajectory of the chain 4000 is inside the frame 1000, thereby reducing the occupied space of the frame 1000. The guide sprockets 8000 are symmetrically arranged on both sides of the middle part of the frame 1000 according to the number and motion route of the chains 4000, thereby optimizing the motion trajectory of the chains 4000 and reducing the occupied space of the frame 1000.

[0068] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the vertical elevator 1 also includes a discharge chute 13000 and a transition sprocket 9000. The discharge chute 13000 is arranged on one side of the frame 1000, and the transition sprocket 9000 is arranged below the first sprocket 2000 in the frame 1000. The transition sprocket 9000 adjusts the inclination of the chain 4000 and the chain bucket 5000 so that the opening of the chain bucket 5000 faces the notch of the discharge chute 13000, so that the material falls into the discharge chute 13000 accurately.

[0069] In some embodiments of the present application, the first sprocket 2000 , the second sprocket 3000 , and the transition sprocket 9000 are symmetrically arranged according to the number of chains 4000 , so as to ensure the stability of the chains 4000 and the material lifting efficiency.

[0070] Figure 6 It is a front view of a falling material recovery device 7000 of a vertical hoist 1 according to an embodiment of the present application.

[0071] In some embodiments of the present application, Figure 2 and Figure 6As shown, in order to solve the problem of residual materials falling from the chain 4000 and the chain bucket 5000 when the chain 4000 and the chain bucket 5000 move to the tensioning device 6000, a material recovery device 7000 is provided below the tensioning device 6000. The material recovery device 7000 includes a recovery drive structure 7100, a scraper 7200 and a material chute 7300. The material chute 7300 is provided below the tensioning device 6000 and is used to collect the material; the driving end of the recovery drive structure 7100 is connected to the scraper 7200, which is used to drive the scraper 7200 to recover the material in the material chute 7300 into the sealed space of the frame 1000, thereby solving the problem that the materials are easily accumulated below the tensioning device and realizing the recycling of the materials.

[0072] For example, Figure 6 As shown, the recovery drive structure 7100 includes: a driving wheel 7110 for receiving driving force; a driven wheel 7120, which is arranged at the other end of the blanking recovery device 7000; a recovery chain 7130, which connects the driving wheel 7110 and the driven wheel 7120; and a scraper 7200 connected to the recovery chain 7130. The scraper 7200 moves between the driving wheel 7110 and the driving wheel 7120 along with the recovery chain 7130, so that the blanking on the blanking chute 7300 moves to the bottom of the frame 1000, so as to realize the recycling of materials. In order to solve the problem of loosening of the recovery chain 7130 after a long time, a recovery tensioning structure 7140 can be connected to the driven wheel 7120 to solve the problem of tensioning the recovery chain 7130.

[0073] In some embodiments of the present application, Figure 2 As shown, in order to solve the problem of flammable materials in the process of using the vertical hoist 1 in a coal-fired power plant, a variety of safety devices can be set inside the cover 10000.

[0074] For example, in order to solve the problem of flammable materials, when a top cover 10100 is set at the top of the rack 1000, a fire sprinkler device 20000 and a gas dust concentration detection device 21000 can be set at an appropriate position on the inner wall of the top cover 10100. The gas dust concentration detection device 21000 can detect the concentration of toxic, flammable and explosive gases and dust such as carbon monoxide, oxygen, methane, and hydrogen sulfide. When the above concentration exceeds the design value, the gas dust concentration detection device 21000 provides an alarm signal. An open fire monitoring device 23000 is installed on the inner wall of the rack cover 10200. When the open fire monitoring device 23000 detects an open fire and sends an alarm signal, the fire sprinkler device 20000 starts to work to ensure the safety inside the rack cover and avoid fire. The open fire monitoring device 23000 includes a temperature measuring cable and a protective tube. The temperature measuring cable is arranged in the protective tube, and the protective tube is arranged on the cover 10000.

[0075] In some embodiments of the present application, Figure 2 As shown, in order to meet the environmental protection production requirements of coal-fired power plants and cement plants, a dry mist dust suppression device 22000 is set on the inner wall of the frame cover 10200 to suppress the dust in the vertical hoist 1, so that the above-mentioned vertical hoist 1 can meet the strict environmental protection production requirements and prevent dust pollution when applied to coal-fired power plants and cement plants.

[0076] In some embodiments of the present application, Figure 2 As shown, in order to solve the problem of difficult maintenance of large and underground vertical hoist 1, one or more observation windows 24000 and maintenance doors 25000 are arranged on the cover 10000 to facilitate maintenance and inspection of the equipment.

[0077] like Figure 2 As shown, a vertical hoist 1 system includes: the above-mentioned vertical hoist 1, a loader 2, a feeder 4 and a dust removal device 5.

[0078] The feeder 2 is connected to the vertical hoist 1 through the feed chute 12000, and is used to input the materials to be lifted into the vertical hoist 1. For example, when conveying coal blocks, the feeder 2 can be a feeder belt conveyor.

[0079] The feeder 4 is connected to the vertical hoist 1 through the discharge chute 11000, and is used to receive the material output by the vertical hoist 1. For example, when the hoist 1 is used to dig coal, the feeder 4 can be used as a coal feeder to evenly transfer the coal to a belt conveyor, other screening equipment or a storage warehouse.

[0080] The dust removal device 5 is used to remove dust in the air inside the vertical lift 1, and is connected to the vertical lift 1 through an air suction channel 28000 provided on the frame 1000 and / or the cover 10000, and is used to remove dust inside the frame. The air suction channel 28000 includes an air suction pipe 28100 and an air suction port 28200.

[0081] The above-mentioned discharge chute 11000 and feed chute 12000 can be installed with a material blocking limiter 26000 and a silo wall vibration motor 27000 to increase the material feeding and discharging rates.

[0082] The working principle of the vertical lifting machine 1 in this embodiment includes:

[0083] According to the principle of tensioning the chain 4000, the chain bucket 5000 moves vertically downward along with the chain 4000 to the guide sprocket 8000 and bypasses the tensioning sprocket 6200; an adjusting driving force is applied to the tensioning adjustment structure 6100, and under the action of the adjusting driving force, the driving end of the tensioning adjustment structure 6100 drives the tensioning sprocket 6200 to move, and then the tensioning chain 4000 is tensioned through the tensioning sprocket 6200.

[0084] Principle of lifting materials, materials enter the vertical elevator 1 from the feed chute 12000; the chain bucket 5000 opens downward and begins to bypass the second sprocket 3000 along with the chain 4000. In the process of the chain bucket 5000 bypassing the second sprocket 3000, the chain bucket 5000 digs the materials from the bottom of the frame 1000 into the chain bucket 5000; after bypassing the second sprocket 3000, the chain bucket 5000 opens upward, and the materials loaded are lifted to the first sprocket 2000 along with the chain 4000; after the chain bucket 5000 bypasses the first sprocket 2000 along with the chain 4000, under the action of the transition sprocket 9000, the position and direction of the chain bucket 5000 are adjusted so that the opening of the chain bucket 5000 faces the discharge chute 13000, and then, the materials in the chain bucket 5000 are discharged into the material chute 13000 under the action of gravity, completing the feeding and discharging of the vertical elevator.

[0085] The vertical hoist 1 mentioned above realizes the tensioning operation of the chain 4000 by arranging the tensioning device 6000 in the middle part of the frame 1000, thereby solving the problems of difficulty in arranging the tensioning device of the super-high vertical hoist 1, large space occupied, and difficulty in maintaining the equipment.

[0086] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
