Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stacking and taking material and dust suppression equipment of small material yard, especially to a small material yard of automatic stacking and taking material. BACKGROUND

[0002] At present, large material yards mostly use large equipment such as bucket wheel machines, circular stacking and taking machines and scraper reclaimers, which are too large to be suitable for small material yards. Traditional ordinary coal yards generally directly load coal into coal wagons, unload coal and then use loaders to stack coal. The presence of various vehicles in the coal yard will inevitably occupy a certain area in the coal yard, affecting the coal storage capacity of the coal yard. Coal is taken by small trolleys or grab cranes. These all require a certain number of personnel to operate on site, the site environment is poor, and the degree of automation is relatively low.

[0003] With the increasing environmental protection requirements, material yards with dust generally need full-coverage spraying facilities. Since the top of the material yard is relatively high, the daily maintenance of the spray head has always been a problem. It needs to use a crane or a professional lifting device to go up. After the coal is stacked on site, the crane and other equipment cannot pass through the area with large coal piles, so the coal needs to be transported before the spraying facilities on the top of the area can be processed, resulting in a large amount of work.

The out-of-yard device is arranged below the grabbing device and placed on the ground. The grabbing device is arranged above the inside of the material yard. The in-yard device is arranged on one side of the material yard. A micro-mist dust suppression device is installed on the lower surface of the roof of the material yard.

[0006] Preferably, the grabbing device comprises a travelling crane, the travelling crane is slidably connected to the side wall of the material yard through a travelling crane track wheel, the travelling crane track wheel is arranged in a travelling crane track, the travelling crane track is arranged on the opposite side walls of the material yard, a grab crane is installed on the travelling crane, the grab crane is slidably connected to the travelling crane through a grab crane track wheel, the grab crane track wheel is arranged in a grab crane track, and the grab crane track is arranged on the travelling crane.

[0007] Preferably, the out-of-yard device comprises an out-of-yard belt conveyor, a coal blending machine is installed on the out-of-yard belt conveyor, the coal blending machine comprises a hopper and a weighing coal feeder, the weighing coal feeder is arranged below the hopper, and the out-of-yard belt conveyor is installed below the weighing coal feeder.

[0008] Preferably, the in-yard device comprises an in-yard belt conveyor, the in-yard belt conveyor is arranged on a steel structure platform, a discharging vehicle is installed on the in-yard belt conveyor, and the transverse belt of the discharging vehicle is a telescopic belt conveyor.

[0009] Preferably, the bottom of the track is provided with a bracket.

[0023] Example 1

[0024] like Figs. 1-2 As shown, the utility model provides a small material yard for automated stacking and reclaiming, including a grabbing device, a discharging device and an in-stock device. The discharging device is provided below the grabbing device, and the discharging device is placed on the ground. The grabbing device is placed above the interior of the material yard 9, and the in-stock device is placed on one side of the material yard 9. A micro-mist dust suppression device 7 is installed on the lower surface of the roof 6 of the material yard 9. The grabbing device is used to grab the coal, the in-stock device is used to transport the coal to the interior of the material yard 9, and the discharging device is used to mix the coal grabbed by the grabbing device and transport it to the outside. The micro-mist dust suppression device 7 uses an existing device to perform dust suppression operations inside the material yard 9 to prevent excessive coal dust. The micro-mist dust suppression device 7 maintains a suitable and close safety distance from the vehicle 5 below to facilitate daily maintenance.

[0025] The grabbing device includes a trolley 5, which is used to move the grab crane 4. The trolley 5 is slidably connected to the side walls of the material yard 9 via trolley rail wheels 16. These trolley rail wheels 16 are positioned within trolley tracks 15, which are located on opposite sides of the material yard 9. These trolley rail wheels 16 support the trolley 5 as it slides within the tracks 15. Corbels 8 are mounted at the bottom of the tracks 15 to support the tracks 15, and thus the trolley 5.

[0026] A grab crane 4 is mounted on the trolley 5 and is used to grab various types of coal. The grab crane 4 and the trolley 5 are slidably connected via grab track wheels 18. These wheels are located within grab tracks 17, which are mounted on the trolley 5. These tracks support the grab crane 4 as it slides left and right on the trolley 5. The left and right sliding of the grab crane 4 and the forward and backward sliding of the trolley 5 ultimately allow the grabbing of various types of coal.

[0027] The out-of-warehouse device comprises an out-of-warehouse belt conveyor 10, which is used for sending the coal to the coal using device outside the stockyard 9. The out-of-warehouse belt conveyor 10 is provided with a coal blending machine 13, which is used for blending the coal. The coal blending machine 13 comprises a hopper 12 and a weighing coal feeder 11 arranged below the hopper 12, wherein the weighing coal feeder 11 is used for weighing the coal, the hopper 12 is used for placing the coal grabbed by the grab crane 4, and the number of the coal blending machine 13 can be configured according to the coal type. The weighing coal feeder 11 is provided with the out-of-warehouse belt conveyor 10 below, and the out-of-warehouse belt conveyor 10 can be arranged on the ground or underground.

[0028] The in-warehouse device comprises an in-warehouse belt conveyor 14, which is used for transporting the coal to the stockyard 9. The in-warehouse belt conveyor 14 is arranged on the platform of the steel structure 1, and the steel structure 1 is fixedly connected with the sidewall of the stockyard 9, and the steel structure 1 is used for supporting the in-warehouse belt conveyor 14. The in-warehouse belt conveyor 14 is provided with a dumper 2, and the transverse belt of the dumper 2 is a telescopic belt conveyor 3. The dumper 2 and the telescopic belt conveyor 3 unload the coal to the coal stacking area, different coal types are stored in different areas, and the telescopic belt conveyor 3 can realize long-distance and short-distance conveying. The dumper 13, the grab crane 4 and the travelling crane 5 are all controlled by an unattended system, and automation is realized.

[0029] When the small stockyard with automatic stacking and unstacking is used, the dumper 2 is driven by the in-warehouse belt conveyor 14 on the steel structure 1 to enter the stockyard 9, then different coal types are transported to the coal stacking area by the dumper 2 and the telescopic belt conveyor 3, and different coal types are stored in different areas. Then the grab crane 4 is driven by the travelling crane 5 to grab different coal types, and the coal types are grabbed into the corresponding hopper 12 to complete the coal unstacking operation. After being weighed, the coal is sent to the out-of-warehouse belt conveyor 10 to be blended, and then is sent to the coal using device outside the stockyard 9.

[0030] Therefore, the small stockyard with automatic stacking and unstacking can further expand the unloading range by using the telescopic belt conveyor, reduces the unloading workload and increases the stockyard storage capacity. The number of the coal blending machine is flexible, the coal type proportion is measured by weighing, and the coal blending is convenient and accurate. The upper micro-mist dust suppression nozzle and other equipment can be directly maintained and repaired through the travelling crane platform, without using other climbing equipment, which is convenient and fast. The unattended control system is adopted, and the stockyard can be unmanned by operating in the central control room.
