Description

Technical Field

[0001] The utility model relates to the field of dock material transportation, in particular to a bulk material transportation system for a large-scale dock yard. Background Art

[0002] With the rapid development of the economy, the demand for mineral resources is increasing. Many resources require large, long-term reserves, which necessitates larger sites for long-term storage of these materials. Existing bulk material conveying systems offer short material storage times and small stockpiles (generally no wider than 100m). These systems typically utilize track-based stacking / reclaiming equipment coupled with ground-based belt conveyors. This requires a regularly distributed stockpiling area and significant site size restrictions. If materials require long-term storage, large stockpiles (greater than 100m wide), and irregularly positioned stockpiles, existing conveying solutions are less suitable, leading to difficult equipment selection or unconventional specifications, low equipment utilization, and high investment and maintenance costs.

[0003] In addition, for the material transfer of large-sized stockpiles, there is also a solution that uses a forklift plus a simple mobile belt conveyor for transportation. However, this solution has simple equipment, a low degree of automation, difficulty in movement, low production efficiency, and almost no supporting environmental protection equipment, which can easily cause huge environmental pollution.

[0054] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0056] The following is combined with Figure 1-12 The bulk material conveying system for a large-scale storage yard at a terminal according to an embodiment of the present utility model is described in detail.

[0057] like Figure 1 、 Figure 4 、 Figure 7 and Figure 10As shown, the bulk material conveying system for a large-scale yard at a terminal according to an embodiment of the present invention is used for conveying materials between the terminal and a material storage area 40. The material storage area 40 is provided with a transfer material storage area 41 on one side close to the terminal and a storage material storage area 42 on the other side.

[0058] The conveying system may include: a wharf ground belt conveyor 10 , a transfer bridge unit 20 and a stacker-reclaimer unit 30 .

[0059] The wharf conveyor 10 is located near a transfer stockpile 41, with transfer stockpile 41 located on one or both sides of the conveying direction of the wharf conveyor 10. The wharf conveyor 10 is used to transport materials from the wharf to the stockpile 40, or to transport materials from the stockpile 40 to the wharf.

[0060] The transfer bridge unit 20 is installed between the storage material pile area 42 in the material pile area 40 and the dock ground conveyor 10. The transfer bridge unit 20 is used to transfer materials transported from the dock by the dock ground conveyor 10 to the storage material pile area 42, or to transfer materials from the storage material pile area 42 to the dock ground conveyor 10 for transportation to the dock.

[0061] The stacker-reclaimer unit 30 is disposed at one end or both ends of the transfer bridge unit 20 . The stacker-reclaimer unit 30 is used to receive materials and transport them to the transfer bridge unit 20 , or receive materials transported by the transfer bridge unit 20 and output them.

[0062] The transfer bridge unit 20 and the stacker-reclaimer unit 30 are both movable. In addition, the wharf ground belt conveyor 10 can be fixed.

[0063] That is to say, according to the bulk material conveying system of the large-scale storage yard of the terminal embodiment of the present invention, the transfer material pile area 41 is distributed on one side or both sides of the conveying direction of the terminal ground belt conveyor 10, and a combined and connected stacker-reclaimer unit 30 and a transfer bridge unit 20 are arranged in the material pile area 40. Thus, the material on the terminal can be transported to the transfer material pile area 41 or the storage material pile area 42 through the terminal ground belt conveyor 10, the transfer bridge unit 20 and the stacker-reclaimer unit 30; or the material at the storage material pile area 42 can be transported to the transfer material pile area 41 through the transfer bridge unit 20 and the stacker-reclaimer unit 30; or the material at the storage material pile area 42 can be transported to the terminal ground belt conveyor 10 through the transfer bridge unit 20 and the stacker-reclaimer unit 30, and then transported to the terminal through the terminal ground belt conveyor 10.

[0064] According to the bulk material conveying system for a large-scale storage yard at a terminal in an embodiment of the present invention, by adopting different combinations of a mobile transfer bridge unit 20 and a stacker-reclaimer unit 30, it is possible to realize material conveying of different process paths, flexibly meet different conveying needs, and solve the problems of difficulty in storing and transferring materials in large-scale storage piles, low production efficiency, low degree of automation of transfer equipment, low degree of environmental protection, inconvenient movement, and low equipment utilization rate.

[0065] In some embodiments, as Figure 2 、 Figure 3 、 Figure 8 and Figure 9 As shown, the stacker-reclaimer assembly 30 may include a crawler-type reclaimer 31 .

[0066] The crawler reclaimer 31 is arranged between the transfer material pile area 41 and the transfer bridge unit 20, or between the storage material pile area 42 and the transfer bridge unit 20. The crawler reclaimer 31 is used to transport materials from the transfer material pile area 41 or the storage material pile area 42 to the transfer bridge unit 20.

[0067] Specifically, when the crawler reclaimer 31 is reclaiming materials, its bucket wheel rotates to reclaim materials from the transfer stockpile 41 or the storage stockpile 42. The materials are transported by the cantilever belt conveyor of the crawler reclaimer 31, and then sent to the crawler reclaimer 31's relay belt conveyor through the hopper on the crawler reclaimer 31. The materials then fall onto the transfer bridge unit 20 through the relay belt conveyor hopper. In other words, the crawler reclaimer 31 can conveniently transfer materials from the stockpile (e.g., the transfer stockpile 41 or the storage stockpile 42) to the transfer bridge unit 20.

[0068] In some embodiments, the rotation angle of the crawler reclaimer 31 is -180° to +180°, and the pitch angle of the boom of the crawler reclaimer 31 is -13° to +13°.

[0069] Therefore, the crawler reclaimer 31 can be moved and can also adjust the pitch angle when reclaiming materials according to the height of the material pile, and can also adjust the position of reclaiming materials by rotating according to the amount of materials reclaimed at the corresponding position of the material pile.

[0070] In some embodiments, as Figure 5 and Figure 6 As shown, the stacker-reclaimer assembly 30 further includes a bucket wheel stacker-reclaimer 32 .

[0071] The bucket wheel stacker and reclaimer 32 is movably disposed above the wharf ground conveyor 10 along the conveying direction of the wharf ground conveyor 10 .

[0072] The bucket wheel stacker and reclaimer 32 is located between the wharf ground belt conveyor 10 and the transfer bridge unit 20 for connection. The bucket wheel stacker and reclaimer 32 is used to transport materials on the wharf ground belt conveyor 10 to the transfer bridge unit 20 .

[0073] That is to say, a bucket wheel stacker and reclaimer 32 movable along the conveying direction of the wharf ground belt conveyor 10 is arranged above the corresponding wharf ground belt conveyor 10, so as to set up multiple conveying lines along the conveying direction of the wharf ground belt conveyor 10. The bucket wheel stacker and reclaimer 32 moves above the wharf ground belt conveyor 10 to transport materials to the storage material pile area 42 on multiple conveying lines, making the setting of the entire conveying system more flexible, improving the material conveying efficiency, and maximizing the utilization of the site area.

[0074] In some embodiments, the slewing angle of the bucket wheel stacker reclaimer 32 is -110° to +110°, and the boom pitch angle of the bucket wheel stacker reclaimer 32 is -13° to +13°.

[0075] Therefore, the bucket wheel stacker and reclaimer 32 can be moved and can also adjust its pitch angle to adapt to the height of the unloading material, and can also adjust the feeding angle by rotating according to the position of the transfer bridge unit 20, which is flexible and convenient, and effectively improves production efficiency.

[0076] In some embodiments, as Figure 2 、 Figure 5 、 Figure 8 and Figure 11 As shown, the transfer bridge unit 20 may include a transition transfer bridge machine 21, a receiving transfer bridge machine 22 and a relay transfer bridge machine 23 that are combined and connected with each other.

[0077] The length of the transition bridge crane 21 is 0-50m, and the pitch angle of the conveyor belt of the transition bridge crane 21 is 0-13°. Specifically, the transition bridge crane 21 is composed of a crawler-type walking mechanism, a conveyor belt, a hopper, an electrical control system, a monitoring and alarm system, a windproof anchoring and anti-overturning device, a power supply, a communication system, lighting, and a metal structure. When the transition bridge crane 21 is performing a conveying operation, the material falls onto the conveyor belt through the tail hopper on the machine, and then is transported to the receiving transfer bridge crane 22 through the head hopper of the conveyor belt. The transition bridge crane 21 has functions such as fixed-point feeding and walking feeding.

[0078] The length of the receiving and transferring bridge crane 22 ranges from 0 to 60 meters, and the belt conveyor of the receiving and transferring bridge crane 22 is fixed at a 0° setting angle. Specifically, the receiving and transferring bridge crane 22 comprises a crawler-type traveling mechanism, a receiving belt conveyor, a hopper, an electrical control system, a monitoring and alarm system, windproof anchoring and anti-overturning devices, power supply, communications, lighting, and metal structures. When the receiving and transferring bridge crane 22 is in operation, material falls through the onboard material guide chute onto the onboard belt conveyor. The material is then transported through the belt conveyor head hopper to the stacker-reclaimer unit 30 or the relay transfer bridge crane 23. The receiving and transferring bridge crane 22 has functions such as fixed-point feeding and traveling.

[0079] The length of the relay transfer bridge crane 23 ranges from 0 to 50 meters, and the angle of its belt conveyor is fixed, ranging from 0 to 13 degrees. Specifically, the relay transfer bridge crane 23 consists of a crawler-type traveling mechanism, a belt conveyor, a hopper, an electrical control system, a monitoring and alarm system, windproof anchoring and anti-overturning devices, power supply, communications, lighting, and metal structures. When the relay transfer bridge crane 23 is in operation, materials fall through the rear hopper onto the belt conveyor. The materials are then transported through the head hopper of the belt conveyor to the transition bridge crane 21, the stacker-reclaimer unit 30, or other relay transfer bridge cranes 23. The relay transfer bridge crane 23 has functions such as fixed-point feeding and traveling.

[0080] That is to say, the transfer bridge unit 20 is composed of a transition transfer bridge machine 21, a receiving transfer bridge machine 22 and a relay transfer bridge machine 23. Through the length and angle settings of each device, the layout of the conveyor line in multiple sites and multiple working conditions can be realized, which is flexible and reliable.

[0081] Preferably, the number of the transition transfer bridge crane 21, the material receiving transfer bridge crane 22 and the relay transfer bridge crane 23 is 1-4 respectively.

[0082] In some embodiments, as Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 12 As shown, the transfer bridge machine group 20 may further include a variable-length transfer bridge machine 24 .

[0083] The length of the luffing transfer bridge crane 24 is 0-35m, and the pitch angle of the luffing transfer bridge crane 24 is 0-13°.

[0084] Specifically, the variable-length transfer bridge machine 24 is smaller in length than the other three devices of the transfer bridge machine group 20, so that it can be located between the transition transfer bridge machine 21, the material receiving transfer bridge machine 22 and the relay transfer bridge machine 23, or when the three devices are connected with other devices, it is used to change the conveying direction of the conveyor line (such as turning), and when the intervals between the devices are small, it can achieve the function of transition connection, thereby further improving the flexibility of the conveying system layout.

[0085] In some embodiments, the stacker-reclaimer assembly 30 may further include a telescopic boom stacker 33 and / or a slewing boom stacker 34.

[0086] The telescopic arm stacker 33 and / or the slewing arm stacker 34 is arranged between the transfer material pile area 41 and the transfer bridge unit 20 , or between the storage material pile area 42 and the transfer bridge unit 20 .

[0087] The telescopic arm stacker 33 and the rotary arm stacker 34 are used to receive and output the materials transported by the transfer bridge unit 20.

[0088] The length of the telescopic boom stacker 33 is 0-60m, and the pitch angle of the belt conveyor of the telescopic boom stacker 33 is 0-13°.

[0089] The length of the slewing arm stacker 34 is 0-80m, the pitch angle of the belt conveyor of the slewing arm stacker 34 is -13°-+13°, and the slewing angle is -110°-+110°.

[0090] That is to say, by setting up a combination of a telescopic arm stacker 33 and / or a rotary arm stacker 34, the materials on the transfer bridge unit 20 are transported to the transfer material pile area 41 or the storage material pile area 42, wherein the length of the telescopic arm stacker 33 is adjustable, and the pitch angle of its belt conveyor can be adjusted within the range of 0-13°, and the rotary arm stacker 34 can rotate within the angle range of -110°-+110°, and its pitch angle is adjustable within the range of -13°-+13°. The selection and use of the two can effectively improve the flexibility of the conveying system layout and high production efficiency.

[0091] In some embodiments, as Figure 5 、 Figure 6 、 Figure 11 and Figure 12 As shown, the conveying system may further include a receiving hopper 50 and a moving hopper 60 .

[0092] The receiving hopper 50 is provided between the stacker-reclaimer unit 30 and the transfer bridge unit 20 , and is used for receiving the materials delivered by the stacker-reclaimer unit 30 and delivering them to the transfer bridge unit 20 .

[0093] The mobile hopper 60 is movably arranged above the dock ground conveyor 10 along the conveying direction of the dock ground conveyor 10. The mobile hopper 60 is used to receive the materials conveyed by the transfer bridge unit 20 and convey the materials to the dock ground conveyor 10.

[0094] That is, a receiving hopper 50 is provided between the stacker-reclaimer unit 30 and the transfer bridge unit 20 to facilitate rapid material transfer between the stacker-reclaimer unit 30 and the transfer bridge unit 20. Furthermore, a movable hopper 60 is movably provided above the corresponding terminal conveyor belt 10 to facilitate transport of materials from the transfer bridge unit 20 to the terminal conveyor belt 10 on multiple conveyor lines, where they are then transported to the terminal.

[0095] The following examples illustrate the conveying process scheme of the bulk material conveying system of a large-scale terminal yard in an embodiment of the present invention, which includes an entry transfer process scheme, an entry direct storage process scheme, an exit transfer process scheme, and an exit direct loading process scheme.
