Description
Technical Field
[0001] The utility model relates to the technical field of trestle type coal storage yards, in particular to a trestle type coal storage yard stacking and reclaiming system. Background Art
[0002] The structure of the trestle type coal storage yard is to set up a sky trestle in the coal shed, install a belt conveyor on the sky trestle, and configure an ordinary electric unloading trolley on the belt conveyor to unload coal into the coal shed. Multiple groups of underground coal receiving hoppers are set up in series along the length of the ground in the coal shed, and manual discharge valves or electro-hydraulic discharge valves are set at the discharge ports of the underground coal receiving hoppers as a way of discharging coal. In order to improve the utilization efficiency of the coal shed, generally one coal shed is equipped with two sky trestle bridges and two underground coal transportation corridors. This type of coal yard belongs to a strip coal yard. If you want to increase the storage capacity of the coal shed, you must increase the height of the sky trestle to increase the height of the coal pile or lengthen the length of the coal shed to increase the length of the coal pile and thus increase the coal storage capacity of the coal shed. Based on structural safety and coal demand factors, the coal pile cannot be piled up unlimitedly. Generally, the sky trestle is set at a maximum height of 15 meters above the ground, and the maximum height of the coal pile is 14.5 meters. Therefore, if you want to increase the coal storage capacity of the coal shed, you must increase the length of the coal shed, but the increase in the length of the coal shed leads to an increase in the length of the coal shed grid, which leads to a linear increase in investment costs. In addition, operators operate the discharge valve underground for a long time, which greatly increases the labor intensity and operation risk; at the same time, multiple groups of underground coal receiving hoppers are all hung on the civil structure beams, and the pressure of the coal pile is directly transmitted to the civil structure frame beams through the coal hoppers, and the structural safety and stability are poor; in addition, the discharge of underground coal hoppers is a natural passive discharge, and the discharge continuity is unstable. When large pieces of coal are stuck in the discharge port, the coal discharge cannot be guaranteed. Therefore, it is urgent to propose a trestle-type coal storage yard stacking and reclaiming system to solve the above problems. Utility Model Content

In addition, the buffering capacity of the coal receiving trough is much greater than that of the traditional serial underground coal hopper, which greatly reduces the number of equipment and reduces costs. The impeller coal feeder transfers the coal in the coal receiving trough to the coal discharging belt conveyor, which can realize the continuous and active coal discharging of the coal shed, and eliminates the situation that the traditional coal hopper relies on the gravity of the coal pile to discharge coal discontinuously.

There is no need to set up loosening measures such as compressed air, which reduces dust flying. In addition, due to the lower depth of the coal receiving trough, the amount of civil engineering and costs are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] The trestle-type coal storage yard stacking and reclaiming system provided in this embodiment has a large coal storage capacity, low cost, high working efficiency, and reduced environmental pollution.
[0035] Specific as Figures 1 to 4 As shown, the trestle-type coal storage yard stacking and reclaiming system includes a coal shed 100, a coal unloading trestle 200, a stacking car 300, a coal discharging belt conveyor 500, a coal receiving trough 600 and an impeller coal feeder 700. The coal shed 100 is set on the ground, and the coal unloading trestle 200 is located in the coal shed 100. The stacking car 300 can unload along the length and width of the coal shed 100 on the coal unloading trestle 200, which increases the stacking width, thereby increasing the coal storage capacity and reducing the construction cost of the coal shed 100. The coal receiving trough 600 is set on the ground in the coal shed 100, and is in a closed state except for the coal discharging seam 601; the impeller coal feeder 700 is installed at the coal discharging seam 601, and moves along the length direction of the coal shed 100 on the rail support of the coal discharging belt conveyor 500, and transfers the coal in the coal receiving trough 600 to the coal discharging belt conveyor 500. The trestle-type coal storage yard stacking and reclaiming system abandons the multiple groups of serial underground coal hoppers in the traditional coal yard. By setting a continuous coal receiving trough 600 on the ground in the coal shed 100, an impeller coal feeder 700 is installed at the coal outlet seam 601 of the coal receiving trough 600. The impeller coal feeder 700 can unload at a fixed point or move to replace several manual valves or electro-hydraulic discharge valves at the discharge port of the serial underground coal hopper in the traditional coal yard, thereby improving work efficiency. In addition, the buffering capacity of the coal receiving trough 600 is much larger than that of the traditional serial underground coal hopper, which greatly reduces the number of equipment and reduces costs. The impeller coal feeder 700 transfers the coal in the coal receiving trough 600 to the coal outlet belt conveyor 500, which can realize the continuous and active coal discharge of the coal shed 100, eliminating the situation where the traditional coal hopper discharges coal discontinuously by relying on the gravity of the coal pile. In addition, the coal receiving trough 600 only retains the slit-type coal outlet slit 601 for installing the impeller coal feeder 700 to discharge coal, which can compress the depth of the coal receiving trough 600, avoid the situation of "blockage" of coal flow in the coal receiving trough 600, and do not need to set up measures such as compressed air to loosen the blockage, thereby reducing dust flying. In addition, since the depth of the coal receiving trough 600 is reduced, the amount of civil engineering and the cost are reduced.
[0036] In some embodiments, the stacker 300 unloads materials in the length direction and width direction of the coal shed 100 through a reversible belt conveyor. Figures 1 to 3 As shown, a reversible belt conveyor is provided on the stacking car 300 , and the stacking car 300 is installed on a rail support of a coal stacking belt conveyor 400 , and the coal stacking belt conveyor 400 is installed on the coal unloading trestle 200 .
[0037] In other embodiments, the stacking car 300 unloads in the length direction and width direction of the coal shed 100 through a cantilever beam. However, in order to ensure the balance and safety of the stacking car 300, a separate track needs to be set for the stacking car 300. Figure 4As shown, the cantilever belt stackers are symmetrically arranged on the stacking car 300 , and the stacking car 300 is separately installed on the ground track of the coal unloading trestle 200 .
[0038] like Figure 5 and 6 As shown, a movable baffle 610 is provided at the coal outlet seam 601 of the coal receiving chute 600. When the impeller coal feeder 700 moves along the coal outlet seam 601, the lifting rod 710 of the impeller coal feeder 700 can drive the movable baffle 610 to open and close automatically. A movable coal baffle is provided at the coal outlet seam 601 of the coal receiving chute 600 to block the coal outlet seam 601 of the coal receiving chute 600. When the impeller coal feeder 700 moves along the coal outlet seam 601 of the coal receiving chute 600, the lifting rod 710 drives the movable baffle 610 to open and close automatically, thereby preventing the self-flow phenomenon of coal flow due to coal outlet disturbance.
[0039] The location and number of the coal outlet openings 601 may vary in different embodiments. Figure 1 As shown, in some embodiments, the coal receiving chute 600 is provided with only one coal outlet opening 601 .
[0040] In some other embodiments, see Figure 2 As shown, the coal receiving chute 600 is provided with two coal outlet openings 601 , which are respectively located on both sides of the coal receiving chute 600 .
[0041] To achieve the coal output efficiency of the two coal output seams 601, optionally, continue to refer to Figure 3 As shown, the trestle-type coal storage yard stacking and reclaiming system includes two coal receiving chutes 600 , and each coal receiving chutes 600 has a coal outlet seam opening 601 .
[0042] The trestle-type coal storage yard stacking and reclaiming system also includes a dry mist dust suppression upper branch system 910 , one end of the drag chain of the dry mist dust suppression upper branch system 910 is connected to the stacking vehicle 300 , and the other end is hinged to the middle of the coal unloading trestle 200 .
[0043] The trestle-type coal storage yard stacking and reclaiming system also includes a dry mist dust suppression lower branch system 920, one end of the drag chain of the dry mist dust suppression lower branch system 920 is connected to the frame of the impeller coal feeder 700, and the other end is hinged to the middle of the underground conveying corridor.
[0044] In the above design of the present application, the use of a drag chain solves the problem of mobile supply of public works. The traditional electric unloading trolley can only solve the problem of mobile power supply (tow cable or cable drum method), and cannot realize the supply of public works such as water and gas, so the dry fog dust suppression method at the unloading point is basically impossible to realize. The traditional gap-type coal unloading ditch underbridge impeller coal feeder 700 can only realize power supply by safe busbar or towing cable method. The dust suppression method is to hang a water trough on the wall of the coal unloading ditch, and install a water pump on the impeller coal feeder 700 to absorb water from the water trough and then rely on the water mist nozzle spraying method to suppress dust. Due to the harsh underground environment, the water trough is open-type, the water quality cannot be guaranteed, and the nozzle must be enlarged to prevent blockage of the nozzle diameter, so basically no water mist can be formed, and the water droplets and dust cannot be effectively combined and settled, and the dust suppression effect is poor. Although the dry fog dust suppression system has been widely used in the dust suppression industry, the dust suppression effect has been generally recognized. However, it is rarely used in traditional mobile equipment such as the bridge impeller coal feeder 700 and the electric unloading trolley. The present application adopts the idea of drag chain, which can perfectly concentrate the public engineering pipelines such as water, electricity and gas on it, and supply them as the equipment moves. It not only solves the power supply problem of the equipment, but also solves the problem of water and gas required for dust suppression, and realizes dry fog dust suppression of mobile equipment.
[0045] In this embodiment, the stacking and reclaiming system of the trestle type coal storage yard further includes a PLC control system 800 for controlling the stacking and reclaiming process of the trestle type coal storage yard.
[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
