Description

Technical Field

[0001] This utility model relates to the field of freight technology, and in particular to a vertical material handling and loading system. Background Technology

[0002] The freight transport of bulk materials such as coal, ore, and grain is closely related to everyone's life. In existing railway material handling and loading systems, horizontal conveying equipment (such as belt conveyors and screw conveyors) is typically used for material transport and loading. However, these systems have the following problems:

[0003] 1. Large footprint: Horizontal conveying equipment requires a large installation space, especially when the site is limited, making it difficult to lay out efficiently.

[0004] 2. Low loading efficiency: Traditional loading methods require manual operation or semi-automated equipment, which is slow and prone to material spillage.

[0005] 3. Poor flexibility: The existing system is difficult to adapt to changes in different vehicle models and loading heights, resulting in a complex and inefficient loading process.

[0006] 4. High energy consumption: Horizontal conveying equipment consumes a lot of energy when conveying over long distances, which increases operating costs.

[0007] Therefore, there is an urgent need for a high-efficiency, flexible and energy-saving vertical material handling and loading system to solve the above problems. Summary of the Invention

[0008] In view of the above-mentioned defects or deficiencies in the prior art, the present invention provides a vertical material handling and loading system that can realize vertical material handling and automated loading, reduce floor space, improve loading efficiency, reduce energy consumption, and adapt to the needs of different vehicle models and loading heights.

[0009] The purpose of this utility model is achieved as follows:

[0010] A vertical material handling and loading system includes a material shed with a scraper conveyor inside. The scraper conveyor transports materials to an outlet. A vertical material handling device and a material conveying device are connected to the scraper conveyor at the outlet. The vertical material handling device includes a vertical frame with a vertically rotating chain on it. Multiple tipping hoppers are spaced apart on the vertical chain to receive materials transported by the scraper conveyor. The material conveying device includes a conveying frame with a conical storage silo inside. A weighbridge platform is located at the lower end of the conveying frame for weighing parked freight trucks. A downward-sloping conveying cylinder is located at the upper end of the vertical frame, connecting to the conical storage silo of the material conveying device. The multiple tipping hoppers receiving materials are sequentially lifted by the rotating vertical chain to the upper end of the vertical frame, where they tip over and deliver the materials through the conveying cylinder to the conical storage silo. The lower outlet of the conical storage silo is connected to a material placing machine, which unloads the materials onto the freight trucks parked on the weighbridge platform.

[0011] A further aspect of the solution is that a guide rail is installed at the lower end of the discharge port of the storage silo, and the material distributor is installed at the lower end of the discharge port of the storage silo, which can be moved horizontally back and forth via the guide rail, so as to achieve uniform material distribution to the front and rear of the cargo truck compartment.

[0012] The solution further includes: the material distribution machine includes a storage box connected to the lower discharge port of the conical storage bin; a chute is provided on one side of the lower longitudinal end of the storage box; the chute is a retractable chute; a scraper conveyor belt is provided in the storage box; the scraper conveyor belt is used to send the material discharged from the conical storage bin into the storage box to the chute, and then discharged from the chute into the cargo compartment of a freight truck.

[0013] A further aspect of the solution is that an inductive identification sensor is installed on the upper or side front of the weighbridge platform. The inductive identification sensor is used to identify the vehicle's identity information. Parking space identification sensors are installed on both sides of the weighbridge platform. The parking space identification sensors are used to locate the position of the freight truck on the weighbridge platform.

[0014] The solution further includes a controller. The sensing and identification sensors and the parking space identification sensors are connected to the controller. The controller determines the vehicle's loading information based on the signals from the sensing and identification sensors and the parking space identification sensors, and then performs accurate quantitative loading based on the loading information.

[0015] The beneficial effects of this utility model are: compared with traditional loading stations, this utility model adopts the "storage bin + belt feeder + truck scale" method, which reduces intermediate batching gates, quantitative bins and unloading gates. This not only reduces the space size and number of equipment in the loading station, but also enables more accurate metering control to avoid overloading or underloading.

[0016] The system is equipped with vehicle position detection and vehicle type recognition, using infrared laser or vision sensors to monitor vehicle position changes in real time, ensuring the stability of the loading process. It can automatically adjust loading parameters and increase material conveying speed based on vehicle type, cargo box size, and loading height. The control system includes sensors, a PLC controller, and a human-machine interface, allowing operators to monitor and adjust the system in real time via a touchscreen or remote terminal.

[0017] This utility model system can effectively solve the problems of large footprint, low loading efficiency, poor flexibility and high energy consumption in the existing technology, and has broad application prospects.

[0018] 1. High efficiency and energy saving: The vertical material handling and loading system reduces the horizontal conveying distance, lowers energy consumption, and improves loading efficiency. 2. Small footprint: The vertical material handling unit occupies little space, making it suitable for environments with limited space.

[0019] 3. High degree of automation: The system has automatic material picking, automatic conveying and automatic loading functions, which reduces manual intervention and improves loading accuracy and efficiency.

[0020] 4. High adaptability: The system can adapt to changes in different vehicle models and loading heights, and has high flexibility.

[0021] 5. Green and environmentally friendly: This system adopts a completely sealed structure, with virtually no dust dispersion.

[0022] The present invention will be further explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0025] A vertical material handling and loading system, such as Figure 1 and Figure 2As shown, the vertical material handling and loading system includes a material shed 1, in which a scraper conveyor 101 is installed. The scraper conveyor 101 conveys the material to the outlet. A vertical material handling device 2 and a material conveying device 3 are connected to the scraper conveyor at the outlet. The vertical material handling device includes a steel vertical frame 201, on which a vertical chain 202, driven by upper and lower winches, reciprocates. Multiple tilting hoppers 203 are spaced apart on the vertical chain 202, receiving the material conveyed by the scraper conveyor 101. The material conveying device 3 includes a steel or concrete conveying frame 301. The vertical frame 201 and the conveying frame 301 are connected and fixed by a connecting bridge 4. The conveying frame 301 contains... A conical storage silo 302 is provided with a weighbridge platform 5 at the lower end of the conveying frame. The weighbridge platform 5 is used to weigh and park freight trucks. The vertical frame 201 and the conveying frame 301 are located in a pit lower than the ground level 6. A downward-sloping conveying cylinder 204 is provided at the upper end of the vertical frame 201. The conveying cylinder 204 is connected to the conical storage silo 302 of the material conveying device 3. Multiple tipping hoppers 203 that receive materials are sequentially lifted to the upper end of the vertical frame by the rotating vertical chain 202 and then tipped to send the materials through the conveying cylinder 204 to the conical storage silo 302. The discharge port 303 at the lower end of the conical storage silo 302 is connected to a material placing machine 7. A gate is provided at the discharge port 303. The material placing machine 7 is used to unload materials onto the freight trucks 8 parked on the weighbridge platform.

[0026] Wherein: a guide rail 304 is provided at the lower end of the discharge port 303 at the lower end of the storage silo, and a roller is provided on the material distribution machine 7. A motor drives the roller to roll along the guide rail 304; therefore, the material distribution machine is set at the lower end of the storage silo through the guide rail 304, which can move horizontally back and forth, so as to achieve uniform material distribution to the front and back of the cargo truck body.

[0027] The material distribution machine 7 includes a storage box 701 connected to the lower discharge port of the conical storage bin. A chute 702 is provided on one side of the lower longitudinal end of the storage box 701. The chute is a telescopic chute, which is composed of at least two sleeves that are nested together. The nested sleeves are extended and retracted by a cylinder. A scraper conveyor belt 703 is provided in the storage box. The scraper conveyor belt 703 is used to send the material discharged from the conical storage bin 303 into the storage box 701 to the chute 702, and then discharged from the chute 702 into the cargo compartment of the freight truck 8.

[0028] The loading process of the concrete placing boom is as follows: First, the retractable chute outlet is lowered into the bottom of the carriage to prevent materials from directly hitting the carriage from the air or to prevent materials from scattering and causing dust pollution. Then, the chute gate is opened to start loading. As the materials are unloaded from the chute outlet, the boom is gradually raised until the chute outlet is at the same height as the carriage baffle. After the chute outlet is at the same height as the carriage baffle, the concrete placing boom is moved horizontally backward while keeping the chute gate open until loading is completed.

[0029] In this embodiment: an inductive identification sensor 9, such as an ETC inductive identification sensor, is provided on the upper or side front of the weighbridge platform. The inductive identification sensor is used to identify the vehicle's identity information (including vehicle model, load weight, etc.). Parking space identification sensors 10 are provided on both sides of the weighbridge platform (e.g., using infrared laser or vision sensors, which can monitor the vehicle's position changes in real time to ensure the stability of the loading process). The parking space identification sensors are used to locate the position of the freight truck on the weighbridge platform.

[0030] As an automatic control mechanism, the system also includes a controller (not shown). The induction and identification sensor 9 and the parking space identification sensor 10 are connected to the controller. The controller determines the vehicle's loading information based on the signals from the induction and identification sensor and the parking space identification sensor. After the vehicle is located, the empty vehicle tare weight is recorded first, and then the loading is carried out accurately and quantitatively based on the loading information.

[0031] The elevator of the vertical material handling device in the above embodiment adopts chain drive and is equipped with multiple buckets with a capacity of 0.1~0.5 cubic meters, a lifting speed of 0.3~1.0 m / s, and a conveying capacity of 300~1200 t / h. The lifting height is matched with the height of the loading station. The material is lifted to the top and enters the storage bin of the material conveying device 3 of the loading station through the side coal chute.

[0032] The main structure of the material conveying device 3 at the loading station is made of concrete or steel, with a height of approximately 25 meters. The upper part is a storage silo, the middle part is a belt feeder, and the bottom is a weighing truck scale.

[0033] In this embodiment, when the system starts running, it receives materials through the pit or scraper conveyor according to the type of goods to be loaded and the production plan for the day. The vertical bucket elevator is then started to transport the materials to the storage bin at the loading station. The bin is kept at a capacity of more than 30 tons to ensure that at least one truck is loaded.

[0034] Outside drivers drive their cars into the area below the loading station. Vehicle position identification sensors are installed at both ends of the truck scale. After all vehicles are on the scale, they are weighed empty first. The system automatically records the empty tare weight. Then, the belt feeder is started. Based on the vehicle identification information identified by the ETC sensor, the truck is loaded accurately and quantitatively. Once loading is complete, the truck leaves the loading station.

[0035] The embodiment provides a highly efficient, flexible and energy-saving vertical material handling and loading system, which can effectively solve the problems of large footprint, low loading efficiency, poor flexibility and high energy consumption in the prior art. It has broad application prospects. The system adopts a completely sealed structure, and there is basically no dust dispersion.
