Description

Technical Field

[0001] This utility model relates to the field of waste rock unloading and loading technology, and in particular to an automated device for controlling waste rock unloading and loading on the ground. Background Technology

[0002] Controlling the unloading and loading of gangue at the surface is a crucial step in the coal mining process, involving multiple aspects such as the transportation, unloading, and loading of gangue. Among these, shaft rock grabbing is an important operation in mining engineering, mainly occurring in mining, the construction of long tunnels and underground railways, used to grab rocks after blasting from the shaft working face when excavating passages connecting surface and underground roadways.

[0003] In existing controlled surface waste rock unloading and loading systems, the process involves numerous personnel, including buckets transporting waste rock to a chute platform, discharging it through a chute to a temporary surface waste rock unloading area, and then loaders working with engineering vehicles to transport the waste rock to a designated waste rock storage point. This often results in overlapping unloading and loading processes, potentially leading to situations where buckets unload waste rock at the chute and loaders load waste rock simultaneously. This poses a significant safety risk, as it can easily result in accidents where falling waste rock injures personnel or damages engineering machinery.

[0004] To address the issue of overlapping unloading and loading processes, the rotatable tilting gate effectively isolates unloading from the bucket chute from loading on the surface in both time and space, ensuring inherently safe production. By isolating the unloading and loading processes, mutual influence and interference between the two can be avoided, allowing each process to be completed more focusedly and efficiently.

[0005] However, during the process of controlling the unloading and loading of gangue on the surface, it is not possible to effectively detect whether there is gangue inside the bucket. As a result, a lot of time is wasted in the process of confirming whether there is gangue inside the bucket, which leads to a decrease in overall production efficiency. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated device for controlling surface coal unloading and loading, which solves the problem of frequent overlap between coal unloading and loading processes.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] An automated device for controlling the unloading and loading of coal on the ground includes a support plate. Automatic lifting safety barriers are symmetrically arranged on both sides of the support plate. A safety barrier control cabinet is installed on the side of each automatic lifting safety barrier away from the support plate. The control cabinets are electrically connected to each other on their adjacent sides. Two monitoring and alarm devices are also symmetrically arranged on the adjacent sides of the control cabinets. The monitoring and alarm devices and the automatic lifting safety barriers work together to ensure the safety of the coal unloading area through a dual safety mechanism of audible and visual alarms and safety barriers. This also serves as a warning to passing pedestrians and vehicles.

[0009] As a further improvement of this utility model, two connecting rods are symmetrically fixedly connected to the side of the support plate near the automatic lifting safety fence, and a rotating disk is fixedly connected to the side of each connecting rod away from the support plate. A fixing rope slides on the top surface of each rotating disk. This allows the bucket body to be moved up or down.

[0010] As a further improvement of this utility model, the bottom end of each fixing rope is fixedly connected to a bucket body, and a fixing plate one is fixedly connected to the support plate at the bottom of the connecting rod. Two laser scanning sensors are symmetrically fixedly connected to the bottom of the fixing plate one at positions corresponding to the two bucket bodies. A second fixing plate is fixedly connected to the support plate at the bottom of the fixing plate one. This effectively secures the laser scanning sensors.

[0011] As a further improvement of this utility model, two electric winches are symmetrically fixedly connected to the top of the second fixed plate. Each electric winch is wound with a steel wire rope, and a baffle plate is fixedly connected to the end of each steel wire rope away from the electric winch. A tilting gate is fixedly connected to the bottom of each baffle plate. This allows for control of the tilting gate's rotation.

[0012] As a further improvement of this utility model, a turning trough is rotatably connected to the side of the turning gate away from the baffle plate, and a support beam is fixedly connected to the side of the turning trough near the turning gate. A support frame is fixedly connected to the bottom end of the turning trough, and a limit switch is fixedly connected to the bottom end of the support beam. This provides support for the turning trough.

[0013] As a further improvement of this utility model, each limit switch is electrically connected to a connecting wire on the side near the support frame. The connecting wire passes through the support frame, and the monitoring and alarm device is fixedly connected to the side of the support frame away from the limit switch. The monitoring and alarm device is used to secure the connecting wire to the surface of the support frame. Thus, the monitoring and alarm device can sound an alarm while simultaneously securing the connecting wire.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. The system utilizes limit switches, connecting wires, monitoring and alarm devices, a safety fence control cabinet, and an automatic lifting safety fence. The limit switch activates the safety fence control cabinet, which then controls the rotation of the automatic lifting safety fence. This controls both the monitoring and alarm devices and the automatic lifting safety fence. Before the bucket body unloads waste rock, the monitoring and alarm devices trigger an audible and visual alarm to warn of the impending unloading operation. Simultaneously, the automatic lifting safety fence lowers, creating a closed area that prevents personnel and vehicles from entering. This process automates waste rock unloading warnings. The dual safety mechanism of audible and visual alarms and the safety fence ensures the safety of the unloading area, preventing accidents caused by falling waste rock that could injure personnel or damage vehicles. Furthermore, effective warning and isolation measures ensure the smooth operation of waste rock unloading and reduce production interruptions due to safety accidents. The automatic lifting safety fence clearly delineates the safe and dangerous areas, helping operators better identify and comply with safety regulations.

[0016] 2. Using laser scanning sensors, an electric winch, and a tilting gate, the laser scanning sensor detects the presence of gangue inside the bucket. A programmable control system converts the analog laser scanning signal into a digital signal, controlling the forward and reverse rotation of the electric winch. The tilting gate is then automatically raised and lowered via steel cable traction. This process increases the automation level of the tilting operation, reduces the risks of manual operation, and effectively avoids accidents caused by human error. The automated control system makes raising and lowering the tilting gate simpler and more efficient, eliminating the need for manual operation and greatly simplifying the process. Furthermore, the automated control system can precisely control the tilting gate's movements, avoiding errors and deviations that may occur with manual operation. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] As shown in the figure, an automated device for controlling the loading and unloading of coal on the ground includes a bucket body 105, a laser scanning sensor 107, an electric winch 109, a coal turning gate 202, a coal turning trough 205, a limit switch 207, a monitoring and alarm device 209, and an automatic lifting safety fence 211.

[0026] In this embodiment of the utility model, there are two sets of automatic control devices. The first set is an automatic audible and visual alarm and an automatic lifting device for the safety fence in the temporary unloading area. This set of devices consists of a support beam 203, a limit switch 207, a connecting line 208, a monitoring and alarm device 209, a safety fence control cabinet 210, and an automatic lifting safety fence 211. First, the limit switch 207 is installed at the bottom of the support beam 203. Then, it is connected in series with the connecting wire 208, the monitoring and alarm device 209, and the safety fence control cabinet 210. The monitoring and alarm device 209 fixes the connecting wire 208, thus securing its position. The monitoring and alarm device 209 is installed on the side of the support frame 206. The safety fence control cabinet 210 controls the automatic lifting safety fence 211, causing it to automatically rise and fall under the control of the limit switch 207. Before the bucket body 105 unloads the waste rock, the monitoring and alarm device 209 issues an audible and visual alarm to warn of the impending unloading operation, simultaneously lowering the automatic lifting safety fence 211 to create a closed area, preventing personnel and vehicles from entering. This process automates the unloading warning process, ensuring safety in the unloading area through a dual safety mechanism of audible and visual alarms and a safety fence, preventing accidents caused by falling waste rock injuring personnel and damaging vehicles.

[0027] Secondly, the automatic lifting and lowering control system of the waste rock turning gate 202. This device consists of a laser scanning sensor 107, an electric winch 109, a steel wire rope 201, and a remotely programmable control system. The laser scanning sensor 107 is installed at the bottom of the fixed plate 106 and can determine whether there is waste rock inside the bucket body 105. The electric winch 109 is installed above the fixed plate 108, and the steel wire rope 201 is wound around the surface of the electric winch 109. The steel wire rope 201 is then connected to the waste rock turning gate 202 to control the upward and downward movement of the gate. The analog signal from the laser scanning is converted into a digital signal to control the forward and reverse rotation of the electric winch 109. The traction of the steel wire rope 201 realizes the automatic lifting and lowering of the waste rock turning gate 202. This process improves the automation level of the waste rock turning operation, reduces the risk of manual operation, and effectively avoids unsafe accidents caused by human factors.

[0028] The specific operating steps of this utility model are as follows:

[0029] Step 1: The monitoring and alarm device 209 identifies vehicle and personnel information in the temporary unloading area. If no vehicle or personnel information is identified, it transmits a signal to the programmable control system to activate the laser scanning sensor 107.

[0030] Step 2: After the bucket body 105 moves to the unloading preparation height, the bucket body 105 will be within the working range of the laser scanning sensor 107. The laser scanning sensor 107 scans whether there is gangue or water inside the bucket body 105 and transmits the signal to the programmable control system.

[0031] Step 3: When the scanning signal indicates that the bucket body 105 contains gangue or water, the programmable control system starts the electric winch 109 and releases the steel wire rope 201, thereby controlling the gangue tipping gate 202 to slowly lower onto the support beam 203.

[0032] Step 4: Trigger the travel of limit switch 207 to form a circuit. When the circuit is connected, the monitoring alarm device 209 will emit a red warning color and a voice alarm. At the same time, the safety fence control cabinet 210 of the temporary unloading area will control the automatic lifting safety fence 211 to fall, closing the temporary unloading area and indicating that the unloading operation of the overturning trough 205 is about to begin. Vehicles and personnel are prohibited from entering.

[0033] Step 5: After the unloading of the gangue is completed, the bucket body 105 is raised to the unloading preparation height. The laser scanning sensor 107 will again determine that there is no gangue or water in the bucket body 105 and transmit a signal to the programmable control system. At this time, the electric winch 109 is started in reverse to retract the wire rope 201, thereby slowly raising the gangue tipping gate 202 to a safe state, so that the bucket body 105 can descend.

[0034] Step Six: After the tipping gate 202 leaves the support beam 203, the limit switch 207 will reset, thus forming a circuit break. At this time, the monitoring alarm device 209 will turn off the red warning color and the voice alarm. At the same time, the safety fence control cabinet 210 of the temporary unloading area will control the automatic lifting safety fence 211 to automatically rise. At this time, vehicles and personnel can safely enter the temporary unloading area to carry out loading operations.

[0035] Step 7: When the monitoring and alarm device 209 identifies the vehicle and personnel information in the temporary unloading area, it transmits a signal to the programmable control system, shuts down the laser scanning sensor 107, and controls the bucket body 105 to descend.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
