[0027] Please refer to Figures 1 to 6 , now the mine emergency stop device provided by the utility model will be described. The mine emergency stop device comprises a control box 1, an induction assembly 2 and an emergency stop assembly 3, the control box 1 is provided with an explosion-proof plate 11, the explosion-proof plate 11 is used to divide the inside of the control box 1 into a first chamber 12 and a second chamber 13;

[0028] The induction assembly 2 comprises a sensor 21, a sliding rod 22, a first elastic member 23 and a first magnetic member 24, the sliding rod 22 is arranged in the first chamber 12 and is arranged at an angle with the explosion-proof plate 11, the first magnetic member 24 is connected to the inner end of the sliding rod 22, the sensor 21 is connected in the first chamber 12 and is located at the outer end of the sliding rod 22, the first elastic member 23 is connected in the first chamber 12 and is used to elastically push the sliding rod 22 outward to be connected with the sensor 21;

[0029] The emergency stop assembly 3 comprises a mounting seat 31, an emergency stop rod 32, a second magnetic member 33 and an elastic clamping ball 34. The mounting seat 31 is connected in the second chamber 13 and coaxially arranged with the sliding rod 22. The emergency stop rod 32 is arranged through the mounting seat 31 and slidably connected with the mounting seat 31. The second magnetic member 33 is connected with the inner end of the emergency stop rod 32 and used for attracting the first magnetic member 24 to make the sliding rod 22 away from the sensor 21. The circumferential wall of the emergency stop rod 32 is provided with axially spaced first clamping grooves 321 and second clamping grooves 322. The elastic clamping ball 34 is embedded on the inner circumferential wall of the mounting seat 31 and used for being elastically clamped in the first clamping grooves 321 or the second clamping grooves 322.

[0030] Compared with the prior art, the mine emergency stop device provided by the embodiment is provided with the induction assembly 2 and the emergency stop assembly 3 on the two sides of the explosion-proof plate 11 in the control box 1, which avoids the influence on the sealing performance of the first chamber 12 during the operation of the emergency stop assembly 3, ensures the stable operation of other electrical elements in the first chamber 12, and enables the first elastic member 23 of the induction assembly 2 to elastically push the sliding rod 22 to the position close to the sensor 21, so that the sensor 21 can monitor the sliding rod 22 to feed back the approach signal to the controller, and then the controller can control the execution element to keep in the connected state according to the preset program. When the emergency stop rod 32 of the emergency stop assembly 3 is operated, the second magnetic member 33 is close to the explosion-proof plate 11 and attracts the first magnetic member 24 to drive the sliding rod 22 away from the sensor 21, so that the controller cannot receive the approach signal of the sensor 21, and then determines that the execution element needs to be controlled to be disconnected according to the preset program, thereby achieving the emergency stop effect. The above device realizes the separate installation of the emergency stop assembly 3 and the induction assembly 2, avoids the influence on the sealing performance of the second chamber 13 during the emergency stop operation, and ensures the normal operation of the equipment.

[0031] For the convenience of description, the end of the sliding rod 22 close to the explosion-proof plate 11 is defined as the inner end, and the end away from the explosion-proof plate 11 is defined as the outer end. The end of the emergency stop rod 32 close to the explosion-proof plate 11 is defined as the inner end, and the end away from the explosion-proof plate 11 is defined as the outer end.

[0032] In the embodiment, in order to facilitate the structure installation, the control box 1 adopts the form of two left and right box bodies being spliced with each other, and the two box bodies are mutually buckled to form an inner cavity for installing electrical elements. The explosion-proof plate 11 divides the inner cavity of the control box 1 into the first chamber 12 and the second chamber 13 which are isolated from each other. The first chamber 12 and the second chamber 13 can be respectively sealed by arranging a sealing ring or filling sealing glue on the outer circle of the explosion-proof plate 11 to achieve the effect of mutual isolation. Specifically, the explosion-proof plate 11 is made of explosion-proof glass and has good explosion-proof performance, which can meet the explosion-proof performance under the mine state.

[0033] When the emergency stop assembly 3 is operated, even if the emergency stop rod 32 is axially displaced, water cannot enter the first chamber 12 from the gap between the emergency stop rod 32 and the control box 1, thereby avoiding affecting the normal operation of other electrical elements in the first chamber 12.

[0034] When the sliding rod 22 is pushed, the elastic clamping ball 34 arranged on the mounting seat 31 can be clamped in the first clamping groove 321 or the second clamping groove 322, thereby limiting the axial position of the sliding rod 22. The first clamping groove 321 can correspond to the position of the sliding rod 22 close to the explosion-proof plate 11, and the first magnetic element 24 can be attracted by the second magnetic element 33. The second clamping groove 322 can correspond to the position of the sliding rod 22 away from the explosion-proof plate 11, so that the second magnetic element 33 and the first magnetic element 24 are separated from each other.

[0035] In one possible implementation, referring to Figures 1 to 6 , the sensing assembly 2 further comprises a connecting seat 25 connected in the first chamber 12, the sliding rod 22 penetrates through the connecting seat 25 and is in sliding cooperation with the connecting seat 25, and the sensor 21 is connected to the outer side of the connecting seat 25.

[0036] In this embodiment, the connecting seat 25 in the first chamber 12 facilitates the installation of the sliding rod 22 and the like, the connecting seat 25 can be connected to the inner top wall of the first chamber 12, the sliding rod 22 is in sliding connection with the connecting seat 25, and the main shaft of the sliding rod 22 can be arranged perpendicular to the explosion-proof plate 11, thereby facilitating the guarantee of the attraction effect of the second magnetic element 33 on the first magnetic element 24.

[0037] The sensor 21 is connected to the outer side of the connecting seat 25, that is, the side of the connecting seat 25 away from the explosion-proof plate 11. Under the pushing action of the first elastic element 23, the sliding rod 22 can keep adjacent to the sensor 21, so that the sensor 21 can detect the outer end of the sliding rod 22 to form a proximity signal and send it to the controller. The controller determines and controls the execution element to be in a normal operation state according to a preset program.

[0038] In some embodiments, referring to Figures 1 to 6 , the inner end of the sliding rod 22 is provided with a small-diameter end 26 for mounting the first magnetic element 24, and the first magnetic element 24 is arranged in multiple along the axial direction of the small-diameter end 26.

[0039] In this embodiment, the small-diameter end 26 arranged on the sliding rod 22 is used for mounting the first magnetic element 24, and the step surface between the small-diameter end 26 and the sliding rod 22 is used for axially limiting the first magnetic element 24. In combination with the arrangement of the inner end limiting clamping spring 28 of the sliding rod 22, the first magnetic element 24 can keep stable in the axial position.

[0040] In some embodiments, referring to Figures 1 to 6The slip rod 22 is sleeved with a spacer 27 between the connecting seat 25 and the first magnetic member 24, and the small-diameter end 26 is externally clamped with a limiting snap spring 28 for limiting the axial position of the first magnetic member 24.

[0041] In the embodiment, the spacer 27 is arranged between the first magnetic member 24 and the connecting seat 25 to avoid the adsorption effect therebetween, the spacer 27 is made of non-magnetic material, and the interaction between the first magnetic member 24 and the connecting seat 25 is avoided, thereby ensuring the effective adsorption of the second magnetic member 33 to the first magnetic member 24 in the emergency stop.

[0042] In a possible implementation, referring to Figures 1 to 6 The outer end of the slip rod 22 is provided with a limiting plate 29, the connecting seat 25 is provided with a first hole 251 and a second hole 252, the first hole 251 is located at the outer end of the second hole 252, and the hole diameter of the first hole 251 is greater than that of the second hole 252, the limiting plate 29 is slidingly connected in the first hole 251, and the first elastic member 23 is located between the limiting plate 29 and the hole bottom wall of the second hole 252.

[0043] In the embodiment, the first hole 251 and the second hole 252 with different hole diameters are arranged on the connecting seat 25 to effectively limit the positions of the limiting plate 29 and the first elastic member 23. The limiting plate 29 arranged at the outer end of the slip rod 22 is slidingly connected in the first hole 251. When the second magnetic member 33 adsorbs the first magnetic member 24, the first elastic member 23 is compressed by the limiting action of the hole bottom wall of the second hole 252, the slip rod 22 stops after moving away by a certain distance, and at this time, the first sensor 21 is away from the slip rod 22.

[0044] When the device resumes normal operation, the emergency stop rod 32 moves away from the explosion-proof plate 11, the elastic clamping ball 34 is clamped in the first clamping groove 321, the second magnetic member 33 loses the adsorption effect on the first magnetic member 24, and the slip rod 22 can move away from the explosion-proof plate 11 under the action of the first elastic member 23, so that the first sensor 21 can detect the slip rod 22, and then send a first proximity signal to the controller, so that the controller controls the execution element, and the device can operate normally.

[0045] In a possible implementation, referring to Figures 1 to 6 The mounting seat 31 is connected with the control box 1 through the connecting pieces 35, the connecting pieces 35 are arranged at intervals along the circumference of the mounting seat 31, and the connecting pieces 35 penetrate the side wall of the control box 1 and the mounting seat 31.

[0046] In the embodiment, the mounting seat 31 is connected to the control box 1 through the connecting piece 35, and the connecting piece 35 can be provided in multiple and arranged at intervals in the circumferential direction of the mounting seat 31. Specifically, three, four or five can be provided, which can ensure the reliable connection between the mounting seat 31 and the control box 1.

[0047] In some embodiments, referring to Figures 1 to 6 , the mounting seat 31 has a sleeve 311 provided through the side wall of the control box 1, the emergency stop rod 32 extends to the inside and outside of the control box 1 through the sleeve 311, and the outer end of the emergency stop rod 32 is provided with a button head 323.

[0048] In the embodiment, the sleeve 311 provided on the mounting seat 31 can penetrate the side wall of the control box 1, which facilitates the extension of the emergency stop rod 32 to the outside of the sleeve 311. The outer end of the emergency stop rod 32 is provided with a button head 323, and the cross-sectional area of the button head 323 is greater than that of the emergency stop rod 32, which facilitates the pressing operation by hand and ensures the effectiveness of the emergency stop action.

[0049] In a possible implementation, referring to Figures 1 to 6 , the elastic clamping balls 34 are arranged at intervals in at least two groups in the circumferential direction of the mounting seat 31. The elastic clamping ball 34 includes a second elastic member 341 and a ball body 342. The second elastic member 341 is embedded on the inner circumferential wall of the mounting seat 31 and extends to the central axis side of the mounting seat 31. The ball body 342 is connected to the extension end of the second elastic member 341 and is used for clamping in the first clamping groove 321 or the second clamping groove 322.

[0050] In the embodiment, the elastic clamping balls 34 are arranged in at least two groups and axially limit the emergency stop rod 32 at different positions in the circumferential direction of the mounting seat 31. Specifically, the second clamping groove 322 is arranged on the side away from the explosion-proof plate 11 of the first clamping groove 321. When the elastic clamping ball 34 is clamped in the first clamping groove 321, the device is in a normal running state. When the emergency stop rod 32 is manually pressed, the elastic clamping ball 34 is first retracted out of the first clamping groove 321 and then extends to be clamped in the second clamping groove 322 under the action of the circumferential wall of the emergency stop rod 32. At this time, the second magnetic member 33 can attract the first magnetic member 24, drive the sliding rod 22 to move away from the sensor 21, so that the sensor 21 cannot send a proximity signal to the controller, and then the controller sends a stop instruction to the execution element, thereby realizing the emergency stop operation.

[0051] In a possible implementation, referring to Figures 1 to 6 , the mounting seat 31 is provided with a radial hole penetrating in the radial direction and used for mounting the elastic clamping ball 34. The second elastic member 341 is connected to the radial hole through a screw plug 343. The screw plug 343 is threadedly connected with the radial hole, and the screw plug 343 is located at the outer end of the radial hole.

[0052] In the embodiment, the radial hole arranged on the mounting seat 31 is used for mounting the elastic clamping ball 34, that is, mounting the second elastic member 341 and the ball body 342. In the natural state, the ball body 342 protrudes outward from the inner peripheral wall of the mounting seat 31 and can form a clamping effect with the first clamping groove 321 or the second clamping groove 322. In order to facilitate installation, the screw plug 343 is threadedly connected with the outer end of the radial hole, thereby providing a basis for installation of the second elastic member 341 and ensuring that the second elastic member 341 effectively pushes the ball body 342, thereby satisfying good limiting effect.

[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
