[0018] 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.

[0019] like Figure 1-3 The shown mining tension member device includes a device body 1 and an emergency stop button assembly, the emergency stop button assembly includes a button body 2, the button body 2 is slidably penetrated on the device body 1, and a dial plate 3 is supported on the side branch plate 21 in the button body 2, the side branch plate 21 and the dial plate 3 are L-shaped, and the lower end of the dial plate 3 passes through the corner of the side branch plate 21 and is inserted into the gap between the first signal turntable 22 and the second signal turntable 23 at the tail of the button body 2, and the dial plate 3 can rotate relative to the side branch plate 21, a locking main board 4 is installed in the device body 1, and a micro switch is provided on the locking main board 4, a limit seat 24 is provided on the button body 2, and the limit seat 24 corresponds to the micro switch on the locking main board 1, and a pulling pin 5 is penetrated on both sides of the device body 1, and the pulling pins 5 on both sides are connected by a tension spring 51, and the tail of the pulling pin 5 is in the shape of an empty knife groove and corresponds to the upper end of the dial plate 3.

[0020] As a preferred embodiment, a telescopic sheath 52 is provided at the connection between the pulling pin 5 and the device body 1 .

[0021] As a preferred embodiment, a limiting ring 53 is provided on the drawing pin 5 , and an inner flange 11 is provided in the device body 1 at a position corresponding to the drawing pin 5 , and the limiting ring 53 corresponds to and cooperates with the inner flange 11 .

[0022] The present invention provides a mining tension member device, which is mainly composed of a sheet metal structure and has a simple structure and is easy to operate.

[0023] In an emergency, the steel wire ropes connected to the pull pin at both ends of the tension member device are pulled, and the pull pin 5 overcomes the tension of the tension spring 51 and moves outward. An O-shaped limit ring 53 and a telescopic sleeve 52 are designed between the pull pin 5 and the device body 1 to prevent the intrusion of exposed dust during mutual displacement, and the inner flange 11 limits the displacement limit of the pull pin 5. The empty knife groove designed at the tail end of the pull pin 5 contacts the upper end of the dial plate 3, forcing the dial plate 3 to swing, forcing the button body 2 of the emergency stop button assembly to move, thereby driving the limit seat 24 locked on the button body 2 of the emergency stop button assembly to move, triggering the micro switch on the locking main board 4 to send an emergency stop signal.

[0024] At the same time, the lock tongue piece provided at the outer end of the button body 2 enters the lock head on the assembly weldment of the front panel of the device body 1, and is manually locked to prevent accidental operation.

[0025] When the lock bolt is pressed, the lock bolt and the button body 2 of the emergency stop button assembly fall down, forcing the limit seat 24 locked on the emergency stop button assembly to move, triggering the micro switch on the locking main board 4 to send an emergency stop signal.
