DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] like Figure 1-Figure 6 As shown, the mine intrinsically safe two-way emergency stop locking switch provided in this embodiment includes a main unit 1 and a plurality of emergency stop switches 2, wherein the plurality of emergency stop switches 2 are interconnected through a plurality of connecting wires 3, and the first emergency stop switch 2 and the last emergency stop switch 2 are both connected to the main unit 1 through the connecting wires 3, a wiring terminal 7 is installed on the front of the main unit 1, an operation panel 6 installed on the top of the main unit 1 is provided above the wiring terminal 7, a display panel 5 installed on the front of the main unit 1 is provided above the operation panel 6, and aviation plug connectors 8 that cooperate with each other are installed on both ends of the emergency stop switch 2, both ends of the connecting wire 3 and the main unit 1. Through the coordinated use of a plurality of emergency stop switches 2, a plurality of connecting wires 3 and the main unit 1, the emergency stop switch 2 can be installed at multiple locations underground, so that when any fault occurs during the use of the belt conveyor and an emergency stop is required, the nearby emergency stop switch 2 can be pressed in time to stop the belt conveyor in an emergency, which is more flexible and convenient to use, and can avoid the problem of increased losses due to insufficient timely emergency stop processing.

[0025] The bottom of the emergency stop switch 2 is movably installed with a mounting bracket 4, and the mounting bracket 4 includes a base 401. The top of the base 401 is provided with a mounting groove 402 that cooperates with the emergency stop switch 2. The front and back sides of the base 401 are threadedly connected with locking screws 406. When in use, the emergency stop switch 2 is installed inside the mounting groove 402, and the locking screws 406 are turned to clamp the emergency stop switch 2. The four corners of the base 401 are threadedly connected with threaded rods 403, and the bottom end of the threaded rod 403 is installed with a bottom plate 404. A second through hole 405 is provided on the bottom plate 404. When in use, the threaded rod 403 can be rotated to adjust its length so as to adapt to the uneven environment under the mine, and then the expansion screw is passed through the second through hole 405 to fix the bottom plate 404, the threaded rod 403 and the base 401.

[0026] The emergency stop switch 2 includes a switch body 201, a protective frame 202 is installed on the top of the switch body 201, a button 204 that cooperates with the switch body 201 is installed inside the protective frame 202, and an indicator light 203 located on one side of the protective frame 202 is installed on the top of the switch body 201. When an emergency stop is required, the button 204 is pressed to perform an emergency stop operation through the switch body 201. After the operation is completed, the indicator light 203 will start to illuminate and remind. A locking lock installed on the top of the switch body 201 is provided on one side of the button 204. The locking lock includes a vertical plate 205 installed on the top of the host 1. A limit block 206 is rotatably installed on one side of the vertical plate 205 through a rotating shaft 208, a groove 209 that cooperates with the limit block 206 is opened on the button 204, and a first through hole 207 located above the rotating shaft 208 is opened on the vertical plate 205. After the button 204 moves downward, the limit block 206 with one end stuck in the groove 209 will rotate through the rotating shaft 208, so that the first through hole 207 is completely buckled out. At this time, the staff can use a padlock to pass through the first through hole 207 and then lock it to prevent the switch body 201 from being reset by other personnel. After the fault is eliminated, the emergency stop personnel can unlock and reset it.

[0027] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a mining intrinsically safe two-way emergency stop locking switch provided in this embodiment is as follows:

[0028] Step 1: When in use, install multiple emergency stop switches 2 at multiple locations underground, and then use the connecting line 3 and the aviation plug connector 8 to connect the multiple emergency stop switches 2. After the connection is completed, connect the first emergency stop switch 2 and the last emergency stop switch 2 to the host 1 through the aviation plug connector 8, and then connect the line driving the conveyor to the terminal 7;

[0029] Step 2: When in use, the threaded rod 403 can be rotated to adjust its length so as to adapt to the uneven environment in the mine, and then the expansion screw is passed through the second through hole 405 to fix the bottom plate 404, the threaded rod 403 and the base 401. After the fixation is completed, the emergency stop switch 2 is installed in the installation groove 402, and the locking screw 406 is turned to clamp the emergency stop switch 2;

[0030] Step 3: When an emergency stop is required, press the button 204 to perform an emergency stop operation through the switch body 201. After the operation is completed, the indicator light 203 will start to illuminate as a reminder. At the same time, the information of the emergency stop operation of the switch body 201 will be transmitted to the host 1 through the connecting line 3. At this time, the host 1 will display the position of a switch body 201 performing an emergency stop operation through the display panel 5. After the button 204 moves downward, the limit block 206 with one end stuck in the groove 209 will rotate through the rotating shaft 208, so that the first through hole 207 is completely exposed. At this time, the staff can use a padlock to pass through the first through hole 207 and then lock it to prevent the switch body 201 from being reset by other people.

[0031] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
