DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-4 The structure of a mining emergency stop rotary locking device shown in the figure includes a welding panel 1 and a supporting connecting plate 2. An emergency stop button 3 is installed on the welding panel 1, and a locking main board 21 is provided on the supporting connecting plate 2. The emergency stop button 3 is composed of an emergency stop seat 4 and a rotating core 5. The emergency stop seat 4 is installed on the welding panel 1, and the rotating core 5 is slid through the emergency stop seat 4, and the rotating core 5 rotates with the emergency stop seat 4. The end of the rotating core 5 is sequentially provided with a first signal turntable 51 and a second signal turntable 52, and the front end of the rotating core 5 is provided with a lock card 6. After the rotating core 5 is pressed and vertically extends into the emergency stop seat 4 and rotates horizontally, the lock card 6 is inserted into the lock hole seat on the welding panel 1.

[0022] As a preferred embodiment, a steel ball 41 is installed in the radial hole on the emergency stop seat 4 , and the steel ball 41 is connected to the top screw 43 through a spring 42 .

[0023] As a preferred embodiment, a positioning pin 44 is installed in the radial hole of the emergency stop seat 4.

[0024] As a preferred embodiment, an oil seal is provided at the connection between the rotating core 5 and the emergency stop seat 4 .

[0025] As a preferred embodiment, the rotating core 5 has a built-in light emitting diode 53 , and a light surface 54 is provided at the front end of the rotating core 5 .

[0026] As a preferred embodiment, a spacer 55 is provided on the rotating core 5 between the first signal rotating disk 51 and the second signal rotating disk 52 .

[0027] The present invention mentions a structure of a mine emergency stop rotary locking device, which acts on the amplified emergency stop telephone of the coal mine communication control, and can realize functions such as voice communication, voice alarm, data transmission, and emergency stop belt line. Because the emergency stop rotary locking device can complete the process of pressing the emergency stop button to trigger the vertical action micro switch to send an emergency stop locking signal; and then rotating the emergency stop button to trigger the horizontal action micro switch to send a locking locking signal. Conversely, when unlocking, the emergency stop button can be pulled out only after rotating it in the opposite direction to realize the unlocking function. This greatly improves the safety and reliability of the emergency stop locking device, avoids human error, and provides a guarantee for the automatic control of the underground belt line.

[0028] The steel ball 41, spring 42, and top screw 43 installed in the radial aperture of the emergency stop seat 4 ensure that the steel ball 41 is in close contact with the circular groove and linear groove on the outer diameter of the rotating core 5 and is precisely positioned. An L-shaped guide groove is opened on the outer diameter of the rotating core 5, and a positioning pin 44 is installed in the radial aperture of the emergency stop seat 4. The shaft end of the positioning pin 44 limits the movement trajectory of the L-shaped guide groove of the rotating core 5, ensuring the guiding effect of the vertical pressing action and horizontal rotation action trajectory of the rotating core 5. The end of the rotating core 5 is equipped with a first signal turntable 51, a spacer 55, and a second signal turntable 52. When the rotating core 5 is pressed vertically, the first signal turntable 51 triggers the vertical micro switch on the locking main board to send an emergency stop locking signal; when the rotating core 5 rotates horizontally again, the second signal turntable 52 triggers the horizontal micro switch on the locking main board to send an emergency stop locking signal.

[0029] The rotating core 5 incorporates a built-in LED 53 and a light panel 54, providing a clear warning when the emergency stop lock is engaged. The emergency stop housing 1 incorporates a built-in oil seal to prevent dust from entering the emergency stop button assembly during the operation of the rotating core 5. An O-ring is also installed between the light panel 54 and the rotating core 5. After the LED 53 is installed within the rotating core 5, it is sealed with glue to prevent dust from entering the emergency stop button assembly.

[0030] Two circular grooves designed on the outer diameter of the rotating core 5 mate with the steel ball 41, achieving precise positioning of the rotating core 5 in both the pulling-up and pressing-down positions. Two linear grooves designed on the outer diameter of the rotating core 5 mate with the steel ball 41, achieving precise positioning of the rotating core in both the front and rear positions. An L-shaped through-slot designed on the outer diameter of the rotating core 5, into which the locating pin 44 is inserted, restricts and guides the two motion trajectories of the rotating core 5 in vertical pulling-up and horizontal rotation, i.e., vertical pressing, forward rotation 90 degrees, reverse rotation 90 degrees, and vertical pulling-up. The rotating core 5 is a hollow structure with a built-in light-emitting diode 53; the red pit structure on the outer end surface of the rotating core 5 clearly indicates the unlocked and locked position status of the rotating core; the straight knurled structure on the outer diameter of the outer end of the rotating core 5 is convenient for operation; the hollow groove structure on the outer end of the rotating core 5 is tightly sealed to install the O-ring and the lamp surface 54; the flat square and threaded structure at the end of the rotating core 5 ensures that the first signal turntable 51, the spacer 55, the second signal turntable 52 and the rotating core 5 can achieve vertical and rotational movements as a whole.

[0031] Under normal working conditions, the red concave pit on the emergency stop button 3 aligns with the word "unlock" on the emergency stop sign on the emergency stop seat. When the belt line needs to stop, press the emergency stop button 3, and the first signal dial 51 on the emergency stop button 3 triggers the vertical micro switch on the locking main board 21 to send an emergency stop locking signal. Then rotate the emergency stop button 3 clockwise, and the second signal dial 52 on the emergency stop button 3 triggers the horizontal micro switch on the locking main board to send an emergency stop locking signal. At this time, the red concave pit on the emergency stop button 3 aligns with the word "lock" on the emergency stop sign. At the same time, the lock card 6 corresponds to the lock seat hole on the welding panel 1, and can be manually locked in the holes of the two to further prevent misoperation. On the contrary, manually remove the lock head, rotate the emergency stop button 3 counterclockwise to release the locking signal, and then pull out the emergency stop button 3 to release the emergency stop signal.

[0032] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
