It is installed at the entrance of the underground unloading chute and can automatically open and close the safety door when the vehicle is unloading ore according to the production task, so as to effectively manage the safety door.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This application provides an automatic safety door control device for mine unloading chute, which includes a door opener, a crank assembly, and a switch. The door opener has a fixing hole and is fixed to the door post of the safety door through the fixing hole. One end of the crank assembly is sleeved on the main shaft of the door opener, and the other end of the crank assembly is provided with a mounting seat. The mounting seat is installed on the safety door, and the switch controls the door opener through a PLC.

[0006] Furthermore, in this utility model, the switch includes a photoelectric switch and a reflector, and the photoelectric switch controls the door opener by cooperating with the reflector.

[0007] Furthermore, in this utility model, the PLC is equipped with both automatic and manual control modes, which can be selected by a switch;

[0008] The automatic control method involves controlling the opening and closing of the intermediate relay of the PLC through the electrical signal of the switch, thereby controlling the door opener; the manual control method involves remotely controlling the door opener by connecting the touch screen to the PLC.

[0009] Compared with the prior art, the present invention has at least the following advantages or beneficial effects:

[0010] This invention can improve the efficiency of the current underground unloading chute safety door and solve the problem of collision with the safety door during ore transportation; at the same time, this invention can effectively remotely and manually control the safety door according to the on-site production needs.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1

[0020] This embodiment provides an automatic opening and closing safety door control device for mine unloading chute, such as... Figures 1-3 As shown, it includes a door opener, a crank assembly, and a switch. The door opener has a fixing hole and is fixed to the door post of the safety door through the fixing hole. One end of the crank assembly is sleeved on the main shaft of the door opener, and the other end of the crank assembly is provided with a mounting seat. The mounting seat is installed on the safety door. The switch controls the door opener through a PLC.

[0021] In this embodiment, as Figure 2 As shown, the switch includes a photoelectric switch and a reflector. The photoelectric switch controls the door opener by cooperating with the reflector. The photoelectric switch and the reflector are respectively installed on the walls of the aisle on both sides of the safety door entrance and exit. The photoelectric switch triggers an action signal to be transmitted to the PLC by cooperating with the reflector.

[0022] In a preferred embodiment of this example, such as Figure 3 As shown, the PLC has two control modes: automatic and manual, which can be selected by a switch. The automatic control mode controls the opening and closing of the PLC's intermediate relay through the electrical signal of the switch, thereby controlling the door opener. The manual control mode enables remote control of the door opener by connecting the touch screen to the PLC.

[0023] For automatic control, switch the selector switch to the "Automatic" position. The Siemens PLC programmable controller uses the intermediate relays to control the opening and closing of the safety gate. Three seconds after the train passes the photoelectric switch at the entrance (distinguishing between people and trains), the entrance and exit gates activate simultaneously to open the safety gate. After the train has completely passed the photoelectric switch at the exit, the entrance and exit gates activate simultaneously to close the safety gate. For manual control, switch the selector switch to the "Manual" position. The touchscreen is configured with screen programming and communicates with the PLC to remotely control the opening and closing of the safety gate.

[0024] In summary, the embodiments of this utility model provide an automatic opening and closing safety door control device for mine unloading chute, which has at least the following advantages or beneficial effects:

[0025] This invention can improve the efficiency of the current underground unloading chute safety door and solve the problem of collision with the safety door during ore transportation; at the same time, this invention can effectively remotely and manually control the safety door according to the on-site production needs.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
