Description

Technical Field

[0001] The utility model relates to the field of warning equipment, in particular to an electric warning door device. Background Art

[0002] In the lifting and transportation of inclined lanes in underground coal mines, there are basically multi-level parking lots, and there are personnel working at each level. Conventional horizontal parking lots require a full-time security personnel to set up a warning rope to block the warning. Especially in multi-level parking lots, each lifting operation must arrange multiple operators to carry out the warning work of lifting and transportation, which not only wastes manpower, but also reduces the lifting efficiency. In addition, the mistakes in manually setting the warning will also bring safety hazards. The utility model solves the cumbersome links of manually setting the warning, replaces the manual warning, and avoids the safety hazards caused by the mistakes in manually setting the warning. Utility Model Content

[0003] The utility model aims to provide an electric warning door device to solve the potential safety hazard caused by the error of manually setting the warning during the multi-level lifting operation in the inclined tunnel of the underground mining area of ​​the coal mine.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The utility model comprises a door frame, a winch, a warning door and a controller. The controller is connected to an operating device that needs to be warned. The controller directly controls the winch. The winch is arranged on a crossbeam of the door frame. Guide wheels are arranged on both sides of the winch. A lifting wire rope on the winch extends downward through the guide wheels and is connected to the warning door.

[0006] As a further optimization of the utility model, the warning door is slidably connected to both sides of the door frame, so that the warning door is more stable and safe during the lifting process.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model is that the controller is connected with the device that needs to be alerted, so as to realize the automatic switch action of the raising and lowering of the alert door, so that no one is on duty on site, and the signal machine sends a signal to control the raising or lowering of the alert device to achieve the purpose of alerting and canceling the alert, and the opening and changing state of the alert door are remotely operated, so as to avoid the safety hazards caused by the mistakes of manually setting the alert. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the overall display effect structure of the utility model.

[0010] In the figure: 1 - door frame; 2 - winch; 3 - warning door; 4 - controller; 5 - guide wheel. DETAILED DESCRIPTION

[0011] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, the utility model includes a door frame 1, a winch 2, a warning door 3 and a controller 4. The controller 4 is connected to the operating device that needs to be alerted. The controller 4 directly controls the winch 2. The winch 2 is set on the crossbeam of the door frame 1. Guide wheels 5 are provided on both sides of the winch 2. The lifting wire rope on the winch 2 extends downward through the guide wheels 5 and is connected to the warning door 3. The warning door 3 is slidably connected to both sides of the door frame 1.

[0013] Example 1

[0014] The utility model is used in the warning operation of the inclined tunnel hoist. During use, when the inclined tunnel is lifting materials, the signal on the lifting signal machine controls the rise or lowering of the warning door through the PLC to achieve the purpose of warning and canceling the warning. A door frame 1 is set in the area where the warning is required. When the inclined tunnel hoist is operating, the signal on the lifting signal machine is transmitted to the controller 4 through the PLC. After the controller 4 receives the command, the motor in the retracting winch 2 is energized and starts to reverse. The warning door 3 is pulled down by the lifting wire rope on the winch 2 through the guide wheel 5. The limit block on the reduction box in the winch 2 also starts to move, and the limit sensor is sensed. The control switch 4 receives the command to automatically cut off the power and stop. At this time, the area is in the warning state, and the inclined tunnel can start to lift materials or operate human and vehicle equipment. After the inclined tunnel hoist operation is completed, the signal on the hoisting signal machine is transmitted to the controller 4 through the PLC. After the controller 4 receives the command, the motor in the retracting winch 2 is energized and starts to rotate forward. The warning door 3 is pulled upward by the lifting wire rope on the winch 2 through the guide wheel 5. The limit block on the reduction box in the winch 2 also starts to move, and the limit sensor is sensed, and the control switch 4 automatically cuts off the power and stops. At this time, there is no need to be alert in this area.

[0015] By adjusting the position of the limit sensor, the height of the warning door 3 can be set, and its function is to signal the stop. When the limit sensor is damaged or there is a mechanical jam in the operation of the lifting wire rope of the retractable warning door 3, the overload protector on the control switch implements the protection action, which is to protect the motor on the retractable winch 2 from burning due to overload. The controller 4 is controlled by the signal worker at the upper wellhead through the lifting signal to send a signal to the horizontal electric warning door, and is locked with the hoist signal. When the lifting signal is sent, the electric warning door cannot be raised, and the door can only be raised after the lifting signal stops. In this way, the entry and exit of on-site workers are managed to achieve the effect of safe lifting. All parking lot electric warning door controls are connected through the PLC communication of the lifting signal, which reduces the laying and installation of various cables on site and avoids various faults caused by the lines, making the remote control system more stable and reliable.

[0016] When the device is in use, no personnel are required to be on duty on site, and it can be remotely controlled, which reduces the number of people and increases efficiency, and avoids the mistakes caused by manually setting alarms. It ensures safe production and efficient transportation, and provides escort for the underground inclined tunnel lifting operation.
