[0020] Please also read Figures 1 to 11 , the flameproof human-computer interaction device for mining provided by the present invention is now described. The flameproof human-computer interaction device for mining, the control box 1, the emergency stop button device 2, the control button device 3 and the controller, the control box 1 is provided with a flameproof plate 11, the flameproof plate 11 is used to separate the interior of the control box 1 into a first chamber 12 and a second chamber 13, the controller is electrically connected to the emergency stop button device 2, the control button device 3 and the execution device respectively; The emergency stop button device 2 includes a sliding component 21, a first sensor 22 and an emergency stop component 23. The sliding component 21 and the first sensor 22 are arranged in the first chamber 12. The emergency stop component 23 penetrates the side wall of the control box 1 and extends into the second chamber 13. The emergency stop component 23 can magnetically absorb the sliding component 21 to stay away from the first sensor 22. The first sensor 22 is used to detect the sliding component 21 to generate first proximity information and send the first proximity information to the controller. The control button device 3 includes an elastic button 31, a control magnetic part 32 and a Hall sensor 33. The elastic button 31 passes through the side wall of the control box 1 and extends into the second chamber 13. The control magnetic part 32 is connected to one end of the elastic button 31 close to the explosion-proof plate 11. The Hall sensor 33 is arranged in the first chamber 12. The control magnetic part 32 can be driven by the elastic button 31 to approach the Hall sensor 33. The Hall sensor 33 is used to generate a Hall signal and send it to the controller.

[0021] The mine flameproof human-machine interaction device provided in the present embodiment is compared with the prior art. The mine flameproof human-machine interaction device provided in the present embodiment divides the inner cavity of the control box 1 into a first chamber 12 and a second chamber 13 by arranging a flameproof plate 11 in the control box 1. The sliding component 21 and the first sensor 22 of the emergency stop button device 2 are arranged in the first chamber 12, and the emergency stop component 23 is arranged in the second chamber 13. The Hall sensor 33 of the control button device 3 is arranged in the first chamber 12, and the elastic button 31 and the control magnetic part 32 are arranged in the second chamber 13. The chamber design can be realized to meet the sealing performance of the second chamber 13, thereby ensuring the reliable operation of the electrical components in the first chamber 12, thereby improving the safety and convenience of human-machine interaction. At the same time, the elastic button 31 drives the control magnetic part 32 to approach the Hall sensor 33, and the controller can receive the Hall signal and control the speed of the actuator, thereby improving the human-machine interaction performance of the equipment.

[0022] For ease of description, the end of the sliding component 21 and the emergency stop component 23 close to the explosion-proof panel 11 is defined as the inner end, and the end away from the explosion-proof panel 11 is defined as the outer end. At the same time, the end of the elastic button 31 close to the explosion-proof panel 11 is defined as the inner end, and the end away from the explosion-proof panel 11 is defined as the outer end.

[0023] In this embodiment, in order to facilitate the structural installation, the control box 1 adopts the form of two parts being assembled together to form an inner cavity for installing electrical components. The explosion-proof plate 11 divides the inner cavity of the control box 1 into a first chamber 12 and a second chamber 13 which are isolated from each other. The first chamber 12 and the second chamber 13 can be isolated from each other and sealed separately by setting a sealing ring 46 or filling a sealant on the outer ring of the explosion-proof plate 11. Specifically, the explosion-proof plate 11 can be made of explosion-proof glass, which has a good explosion-proof effect and can meet the explosion-proof performance under the mining state.

[0024] When operating the emergency stop button device 2 or the control button device 3, only the parts of the two in the second chamber 13 are operated, and moisture will not enter the first chamber 12, thereby ensuring the normal operation of other electrical components in the first chamber 12 and improving the safety and stability of equipment operation.

[0025] It should be noted that the Hall sensor 33 is a magnetic field sensor made based on the Hall effect. The Hall effect sensor is a transducer that converts a changing magnetic field into a change in output voltage.

[0026] Specifically, during normal use of the device, the elastic button 31 is pressed to drive the control magnetic part 32 to move closer to the Hall sensor 33. Different magnetic fields are formed according to the different pressing depths of the elastic button 31, so that the Hall sensor 33 generates different Hall signals. After receiving the Hall signal, the controller sends a corresponding control instruction to the actuator to achieve effective control of parameters such as the speed of the actuator.

[0027] When an emergency situation occurs and an emergency stop is required, the emergency stop component 23 of the emergency stop button device 2 is pressed, and the emergency stop component 23 moves to the side close to the sliding component 21, thereby forming an adsorption effect on the sliding component 21, and then the sliding component 21 is moved away from the first sensor 22, and the first sensor 22 stops sending the first proximity signal to the controller. The controller can determine the need for emergency stop processing according to the preset program, and then send an emergency stop command to the execution device to realize the emergency stop operation of the equipment.

[0028] In one possible implementation, see Figures 1 to 11 The sliding assembly 21 includes a sliding rod 211, a first elastic member 212 and a first magnetic member 213. The sliding rod 211 is arranged in the first chamber 12 and is arranged at an angle with the explosion-proof plate 11. The first magnetic member 213 is connected to the inner end of the sliding rod 211. The first sensor 22 is connected to the first chamber 12 and is located at the outer end of the sliding rod 211. The first elastic member 212 is connected to the first chamber 12 and is used to elastically push the sliding rod 211 outward until it is connected to the first sensor 22. The emergency stop assembly 23 includes a mounting seat 231, an emergency stop rod 232, a second magnetic member 233 and an elastic clamping ball 234. The mounting seat 231 is connected to the second chamber 13 and is coaxially arranged with the sliding rod 211. The emergency stop rod 232 passes through the mounting seat 231 and is slidably matched with the mounting seat 231. The second magnetic member 233 is connected to the inner end of the emergency stop rod 232 and is used to adsorb the first magnetic member 213 to make the sliding rod 211 away from the first sensor 22. The circumferential wall of the emergency stop rod 232 is provided with an axially spaced first clamping groove 235 and a second clamping groove 236. The elastic clamping ball 234 is embedded in the inner circumferential wall of the mounting seat 231 and is used to be elastically clamped in the first clamping groove 235 or the second clamping groove 236.

[0029] In this embodiment, the first elastic member 212 of the sliding assembly 21 can elastically push the sliding rod 211 to a position close to the first sensor 22, so that the first sensor 22 can monitor the sliding rod 211 to feedback the first proximity signal to the controller, and the controller controls the execution device to maintain a connected state according to a preset program.

[0030] When an emergency stop operation is required, pressing the emergency stop rod 232 drives the second magnetic component 233 to approach the explosion-proof panel 11 and adsorb the first magnetic component 213, and then uses the first magnetic component 213 to drive the sliding rod 211 away from the first sensor 22. At this time, the first sensor 22 cannot generate a first proximity signal, and the controller determines that it is necessary to control the disconnection of the execution device according to the preset program, thereby achieving an emergency stop effect.

[0031] When the sliding rod 211 is pushed, the elastic card ball 234 provided on the mounting seat 231 can be engaged in the first card slot 235 or the second card slot 236 to limit the axial position of the sliding rod 211. The first card slot 235 can correspond to the position where the sliding rod 211 is close to the explosion-proof plate 11 and the first magnetic member 213 can be adsorbed by the second magnetic member 233, and the second card slot 236 can correspond to the position where the sliding rod 211 is away from the explosion-proof plate 11 and the second magnetic member 233 and the first magnetic member 213 are separated from each other.

[0032] In one possible implementation, see Figures 1 to 11 The sliding assembly 21 also includes a connecting seat 214 connected to the first chamber 12 , the sliding rod 211 passes through the connecting seat 214 and slidably cooperates with the connecting seat 214 , and the first sensor 22 is connected to the outer side of the connecting seat 214 .

[0033] In this embodiment, the setting of the connecting seat 214 facilitates the installation of components such as the sliding rod 211. The connecting seat 214 is connected to the inner top wall of the first chamber 12. The sliding rod 211 is slidably connected to the connecting seat 214. The main axis of the sliding rod 211 can be set perpendicular to the explosion-proof plate 11, so as to ensure the adsorption effect of the second magnetic component 233 on the first magnetic component 213.

[0034] At the same time, the first sensor 22 is connected to the outer side of the connection seat 214, that is, the side of the connection seat 214 away from the explosion-proof plate 11. Under the pushing action of the first elastic member 212, the sliding rod 211 can maintain a state close to the sensor, so that the first sensor 22 can detect the outer end of the sliding rod 211 to form a first proximity signal and send it to the controller, and the controller makes a judgment according to a preset program and controls the actuator to be in a normal operating state.

[0035] For some examples, see Figures 1 to 11 The inner end of the sliding rod 211 is provided with a small diameter end 215 for installing the first magnetic component 213, and a plurality of first magnetic components 213 are arranged in sequence along the axial direction of the small diameter end 215; the sliding rod 211 is provided with a first spacer sleeve 216 located between the connecting seat 214 and the first magnetic component 213, and the outer periphery of the small diameter end 215 is clamped with a limiting spring 217 for limiting the axial position of the first magnetic component 213.

[0036] In this embodiment, a first hole 218 and a second hole 219 with different apertures are provided on the connection base 214, the aperture of the first hole 218 is larger than the space of the second hole 219, and the first hole 218 is located on the end surface of the connection base 214 close to the first sensor 22. The first hole 218 and the second hole 219 respectively effectively limit the positions of the limit plate 2111 and the first elastic member 212. The outer end of the sliding rod 211 is provided with a limit plate 2111 slidably connected to the first hole 218, and the sliding amplitude of the sliding rod 211 is limited by the first hole 218.

[0037] When the second magnetic member 233 attracts the first magnetic member 213, the first elastic member 212 is compressed by the limiting effect of the bottom wall of the second hole 219, and the sliding rod 211 stops after moving away from a certain distance. At this time, the first sensor 22 moves away from the sliding rod 211. When the equipment returns to normal, the emergency stop rod 232 moves to the side away from the explosion-proof plate 11, and is engaged in the first card slot 235 by the elastic card ball 234. The second magnetic member 233 loses its adsorption effect on the first magnetic member 213, and the sliding rod 211 can move to the side away from the explosion-proof plate 11 under the action of the first elastic member 212, so that the first sensor 22 can detect the sliding rod 211, and then send a first proximity signal to the controller, so that the controller controls the actuator and the equipment can operate normally.

[0038] In order to avoid adsorption between the first magnetic component 213 and the connecting seat 214, a first spacer 216 is arranged between the two. The first spacer 216 is made of non-magnetic material, which can avoid interaction between the first magnetic component 213 and the connecting seat 214, thereby ensuring that the second magnetic component 233 effectively adsorbs the first magnetic component 213 during emergency stop.

[0039] On this basis, the mounting seat 231 is connected to the control box 1 through the first connecting member 238. The first connecting member 238 can be provided in plurality and arranged at intervals in the circumferential direction of the mounting seat 231. Specifically, three, four or five first connecting members 238 can be provided to ensure a reliable connection between the mounting seat 231 and the control box 1.

[0040] Furthermore, an emergency stop button 239 may be provided at the outer end of the emergency stop rod 232 , and the cross-sectional area of ​​the emergency stop button 239 is larger than the cross-sectional area of ​​the emergency stop rod 232 , which is convenient for manual pressing operation and ensures the effectiveness of the emergency stop action.

[0041] In one possible implementation, see Figures 1 to 11 A radial hole 237 is radially penetrated on the mounting seat 231, and the elastic clamping ball 234 includes a screw plug 2341, a second elastic member 2342 and a sphere 2343. The screw plug 2341 is threadedly matched with the radial hole 237 and is located at the outer end of the radial hole 237. The second elastic member 2342 is connected to the inner end of the screw plug 2341. The sphere 2343 is connected to the inner end of the second elastic member 2342. The sphere 2343 is used to be clamped in the first clamping groove 235 or the second clamping groove 236.

[0042] In this embodiment, at least two groups of elastic clamping balls 234 are provided to axially limit the emergency stop rod 232 at different circumferential positions of the mounting seat 231. The second clamping groove 236 is provided on the side of the first clamping groove 235 away from the explosion-proof plate 11. When the elastic clamping ball 234 is clamped in the first clamping groove 235, the equipment is in normal operation. When the emergency stop rod 232 is pressed manually, the elastic clamping ball 234 is first retracted and moved out of the first clamping groove 235 by the action of the surrounding wall of the emergency stop rod 232, and then extends outward to be clamped in the second clamping groove 236. At this time, the second magnetic part 233 can absorb the first magnetic part 213, drive the sliding rod 211 away from the first sensor 22, so that the first sensor 22 detects the sliding rod 211, and then sends a stop command to the execution device through the controller to realize the emergency stop operation.

[0043] Specifically, the radial hole 237 provided on the mounting seat 231 is used to install the elastic clamping ball 234, that is, to install the second elastic member 2342 and the sphere 2343. In a natural state, the sphere 2343 protrudes outward from the inner peripheral wall of the mounting seat 231, and can form a clamping effect with the first clamping groove 235 or the second clamping groove 236. In order to facilitate installation, the screw plug 2341 is used to cooperate with the outer end thread of the radial hole 237 to provide a basis for the installation of the second elastic member 2342, ensuring that the second elastic member 2342 effectively pushes the sphere 2343, and satisfies a good limiting effect.

[0044] In one possible implementation, see Figures 1 to 11A button tube seat 34 extending to the second chamber 13 is penetrated through the control box 1, and the elastic button 31 is slidably connected in the button tube seat 34. The elastic button 31 includes a pressing column 311 and a third elastic member 312 sleeved on the outer periphery of the pressing column 311. The third elastic member 312 can elastically push the pressing column 311 to make the pressing column 311 away from the Hall sensor 33 for reset. The control magnetic member 32 is connected to the inner end of the pressing column 311.

[0045] In this embodiment, the elastic button 31 is slidably connected in the button tube seat 34. The reliability of the installation of the elastic button 31 is ensured by setting the button tube seat 34 on the side wall of the control box 1. The two ends of the elastic button 31 protrude outward from the two ends of the button tube seat 34 respectively. The end located outside the control box 1 is used to be pressed, and the end located outside the control box 1 is used to install the control magnetic member 32. The third elastic member 312 is used to drive the pressing column 311 to move to the side away from the Hall sensor 33 to the reset state. When it is necessary to control or adjust the speed of the actuator, the pressing column 311 can be pushed toward the side of the explosion-proof plate 11 to shrink the third elastic member 312. At this time, the pressing column 311 is close to the Hall sensor 33, so that the Hall sensor 33 can detect the Hall signal and send it to the controller to achieve speed control of the actuator.

[0046] For some examples, see Figures 1 to 11 A flange 341 is provided at the outer end of the button cylinder seat 34, a fastening nut 342 which can be pressed against the inner wall of the second chamber 13 is provided on the outer threaded sleeve of the button cylinder seat 34, a limiting ring 343 is provided inside the button cylinder seat 34, and an inner groove 344 for installing the third elastic member 312 is provided on the outer periphery of the button cylinder seat 34, the limiting ring 343 is located in the inner groove 344 and abuts against the third elastic member 312, and the side wall of the limiting ring 343 can abut against the side wall of the inner groove 344 to limit the movement range of the pressing column 311.

[0047] In this embodiment, when the button tube seat 34 is installed on the side wall of the control box 1, in order to facilitate the installation operation, the fastening nut 342 is threadedly matched with the button tube seat 34. By screwing the fastening nut 342, the side wall of the control box 1 is effectively clamped by the flange 341 and the fastening nut 342, thereby improving the reliability of the structural installation.

[0048] The inner groove 344 on the outer periphery of the button tube seat 34 is used to install the third elastic member 312. The inner groove 344 is located in the axial middle part of the button tube seat 34 to facilitate the arrangement of the third elastic member 312 and form an abutment effect with the third elastic member 312 through the limiting ring 343.

[0049] On this basis, multiple elastic buttons 31 and Hall sensors 33 are provided respectively, and multiple elastic buttons 31 and multiple Hall sensors 33 are arranged one by one. In order to facilitate the installation of multiple Hall sensors 33, a PCB board 24 is provided in the first chamber 12, and multiple Hall sensors 33 are installed on the PCB board 24 in a certain order. Multiple elastic buttons 31 are respectively installed on the side wall of the control box 1 close to the second chamber 13, penetrate the side wall of the control box 1 and extend into the second chamber 13. The elastic buttons 31 and the Hall sensors 33 are arranged one by one on both sides of the explosion-proof plate 11.

[0050] In one possible implementation, see Figures 1 to 11 The explosion-proof human-computer interaction device for mining also includes an enabling button device 4, which includes a fixed seat 41, a rotating rod 42, a torsion spring 43, an extension rod 44 and a second sensor 45. The fixed seat 41 passes through the side wall of the control box 1 and extends into the first chamber 12. The rotating rod 42 passes through the fixed seat 41 and is rotatably matched with the fixed seat 41. The extension rod 44 is connected to the inner end of the rotating rod 42 and extends along the radial direction of the rotating rod 42. The extension rod 44 can be driven by the rotating rod 42 to rotate to correspond to the second sensor 45. The second sensor 45 is electrically connected to the controller. The second sensor 45 is used to detect the extension rod 44 to generate second proximity information and send the second proximity information to the controller. The torsion spring 43 is set between the fixed seat 41 and the rotating rod 42 to drive the rotating rod 42 to rotate and reset.

[0051] In this embodiment, the enabling button device 4 is set to feed back the second proximity signal to the controller. After receiving the second proximity signal, the controller starts the Hall sensor 33 according to a preset program, and the control button device 3 can be used to input keys to achieve the control and regulation of the execution device. The enabling button device 4 can control when the control button device 3 is in an invalid state and when it is in a valid state, so as to prevent misoperation and ensure that the execution device can be started to work only after all preparations are completed.

[0052] Specifically, when the control button device 3 needs to be used, the rotating rod 42 is manually driven to rotate, driving the protruding rod 44 at the inner end of the rotating rod 42 to rotate to a position corresponding to the second sensor 45. After the second sensor 45 detects the protruding rod 44, it generates second proximity information and sends the second proximity information to the controller. The controller determines that the Hall sensor 33 needs to be started at this time according to the preset program, and then controls the power supply element to be connected to the Hall sensor 33 to ensure the normal operation of the Hall sensor 33. Only then can the control button device 3 be used to effectively input keys to achieve control and regulation of the execution device.

[0053] For some examples, see Figures 1 to 11The outer end of the fixed seat 41 is provided with a limit stop platform 412 protruding toward the outer circumference, and the limit stop platform 412 is connected to the side wall of the control box 1 through a second connecting piece. A sealing ring 46 capable of abutting against the outer wall of the control box 1 is embedded on the inner end surface of the limit stop platform 412. The outer end of the rotating rod 42 is connected to a rotating disk 421 embedded in the limit stop platform 412, and a radially extending operating handle 47 is connected to the outer end surface of the rotating disk 421.

[0054] In this embodiment, the fixing seat 41 is arranged to penetrate the side wall of the control box 1, and the outer end of the fixing seat 41 is provided with a limit stop 412 located outside the side wall of the control box 1, and the limit stop 412 is connected to the control box 1 through a second connecting member. The sealing performance of the installation position of the fixing seat 41 is ensured by embedding a sealing ring 46 on the inner end surface of the limit stop 412.

[0055] At the same time, a rotating disk 421 is provided at the outer end of the rotating rod 42. The rotating disk 421 is partially embedded in the limit stop platform 412 and partially exposed from the limit stop platform 412 to facilitate the installation of the operating handle 47 and facilitate subsequent manual driving of the operating handle 47.

[0056] For some examples, see Figures 1 to 11 The inner end of the rotating rod 42 is sleeved with a mounting disk 422, and the rotating rod 42 is sleeved with a second spacer 48 located between the mounting disk 422 and the fixed seat 41. The torsion spring 43 is sleeved on the outer periphery of the second spacer 48. An axially extending first plug hole 423 is provided on the outer end surface of the mounting disk 422, and an axially extending second plug hole 411 is provided on the inner end surface of the fixed seat 41. Both ends of the torsion spring 43 are correspondingly inserted into the first plug hole 423 and the second plug hole 411, and the protruding rod 44 is connected to the outer periphery of the mounting disk 422.

[0057] In this embodiment, by arranging a mounting plate 422 at the inner end of the rotating rod 42, it is convenient to install the extension rod 44, and the extension rod 44 can be threadedly connected to the peripheral wall of the mounting plate 422. By arranging a second spacer 48 on the outer periphery of the rotating rod 42, an effective spacing between the rotating disk 421 and the fixing seat 41 is achieved, ensuring that the rotating disk 421 and the second sensor 45 are in corresponding positions in the axial direction of the rotating rod 42, and then when the rotating rod 42 drives the extension rod 44 to rotate, the second sensor 45 can effectively detect the extension rod 44 and send a second proximity signal to the controller.

[0058] Usage process: When the speed of the actuator is adjusted by using the control button device 3, the rotating rod 42 is first driven to rotate so that the protruding rod 44 at the inner end of the rotating rod 42 rotates to a position corresponding to the second sensor 45. After the second sensor 45 detects the protruding rod 44, it generates second proximity information and sends the second proximity information to the controller. The controller determines that the Hall sensor 33 needs to be started at this time according to the preset program, and then controls the power supply element to be connected to the Hall sensor 33 to ensure the normal operation of the Hall sensor 33. At this time, effective input is performed by pressing the pressing rod downward, and the speed and other parameters of the actuator are controlled by the pressing force and depth.

[0059] When an emergency situation occurs and an emergency stop is required, pressing the emergency stop rod 232 drives the second magnetic part 233 to approach the explosion-proof plate 11 and absorb the first magnetic part 213. At this time, the elastic card ball 234 escapes from the first card slot 235 and is engaged in the second card slot 236. The first magnetic part 213 is used to drive the sliding rod 211 away from the first sensor 22. At this time, the first sensor 22 cannot generate the first proximity signal. The controller determines that it is necessary to control the disconnection of the execution device according to the preset program, thereby achieving the emergency stop effect.

[0060] The above-mentioned explosion-proof human-computer interaction equipment for mining is divided into a first chamber 12 and a second chamber 13 by arranging an explosion-proof plate 11 in the control box 1. The sliding component 21 and the first sensor 22 of the emergency stop button device 2 are arranged in the first chamber 12, and the emergency stop component 23 is arranged in the second chamber 13. The Hall sensor 33 of the control button device 3 is arranged in the first chamber 12, and the elastic button 31 and the control magnetic part 32 are arranged in the second chamber 13. The chamber design can be realized to meet the sealing performance of the second chamber 13, thereby ensuring the reliable operation of the electrical components in the first chamber 12, thereby improving the safety and convenience of human-computer interaction. At the same time, the elastic button 31 drives the control magnetic part 32 to approach the Hall sensor 33, and the controller can receive the Hall signal and control the speed of the actuator, thereby improving the human-computer interaction performance of the equipment.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
