DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a fire belt retracting and releasing device for coal mine mining tunnels, comprising a fastener 1, a side end of the fastener 1 is fixedly connected with a fixing plate 101, a side end of the fixing plate 101 is rotatably provided with a rotating rod 2, a side end of the rotating rod 2 is provided with a winding mechanism for winding up the fire belt, an outer end of the rotating rod 2 is fixedly connected with a gear 201, a side end of the fixing plate 101 is provided with a fixing mechanism for limiting the rotation of the gear 201 and the rotating rod 2, a side end of the winding mechanism is provided with a limiting mechanism for limiting the end of the fire belt, through the setting of the fixing mechanism, the winding mechanism can be prevented from rotating clockwise, thereby preventing the fire belt from scattering, and through the setting of the limiting mechanism, the end of the fire belt can be easily limited to avoid the situation where the fire belt scatters.

[0022] As an implementation method in this embodiment, Figure 1 As shown, the winding mechanism includes a limit plate 202, which is fixedly connected to the side end of the rotating rod 2, and the side end of the limit plate 202 is fixedly connected to a winding drum 203, and the side end of the winding drum 203 is fixedly connected to a limit plate 204, and the side end of the limit plate 204 is fixedly connected to a handle 209. During implementation, the fire belt can be easily retracted and released by rotating the handle 209 to drive the winding drum 203 to rotate.

[0023] As an implementation method in this embodiment, Figure 2 and Figure 3The cam 302 is pressed against the top of the gear 201 to release the lever 304, and the cam 303 is pressed against the top of the gear 201 to release the lever 304. When the fire hose is wound up, the reel 203 is driven to reel in the fire hose by rotating the handle 209. At this time, the rotating rod 2 drives the gear 201 to rotate counterclockwise. At this time, when the gear 201 rotates counterclockwise, it will push the card plate 301 to move up, and the card plate 301 will shrink against the spring 305. During the upward movement of the card plate 301, the limit rod 303 moves in the arc groove 102. When the fire hose is wound up and no longer rotates, the spring 305 will push the card plate 301 and be stuck between the two teeth at the side end of the gear 201. With the setting of the limit rod 303, the reel 203 cannot rotate clockwise. At this time, the reel can be prevented from rotating clockwise after winding, thereby preventing the fire hose from being scattered due to the clockwise rotation of the reel 203 after winding.

[0024] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, the side end of the limiting plate 1 202 is fixedly connected with the side plate 205, the side end of the limiting plate 204 is provided with a side groove 206, the side end of the side groove 206 is provided with a slot 207, the inner side of the slot 207 is fixedly connected with a protrusion 208, the limiting mechanism includes a baffle 4, the baffle 4 is rotatably arranged on the side end of the side plate 205, the side end of the baffle 4 is fixedly connected with an elastic plug 401, the side end of the elastic plug 401 is fixedly connected with a press block 402, and the side end of the elastic plug 401 is provided with a notch 403. In implementation, by rotating the baffle 4 to the side of the side groove 206, At the end, press the baffle 4 hard to insert the elastic plug plate 401 into the slot 207. At this time, the protrusion 208 presses the side end of the elastic card plate 301 to cause a certain deformation. When the protrusion 208 passes through the notch 403 at the side end of the elastic card plate 301, it no longer presses the side end of the elastic card plate 301. At this time, the elastic card plate 301 will rebound, so that the protrusion 208 is limited in the notch 403, so that the elastic card plate 301 is fixed in the slot 207, thereby completing the fixation of the baffle 4, so that the end of the fire belt can be limited and fixed to avoid the fire belt from scattering.

[0025] When the fire hose is unwound, the pressing plate 302 is pressed downward to make the clamping plate 301 tilt upward. At this time, the clamping plate 301 is no longer limited between the two teeth at the side end of the gear 201. At this time, the fire hose can be unwound. When the fire hose is unwound, the grip 209 is turned to drive the reel 203 to rewind the fire hose. At this time, the rotating rod 2 drives the gear 201 to rotate counterclockwise. At this time, when the gear 201 rotates counterclockwise, it will push the clamping plate 301 to move upward, and the clamping plate 301 will shrink against the spring 305. During the upward movement of the clamping plate 301, the limiting rod 303 moves in the arc groove 102. When the fire hose is wound up and no longer rotates, the spring 305 will push the clamping plate 301 to be stuck between the two teeth at the side end of the gear 201, cooperating with the setting of the limiting rod 303. , the winding drum 203 is limited so that the winding drum 203 cannot rotate clockwise. At this time, the fire hose after winding can be prevented from rotating clockwise, thereby preventing the fire hose after winding from scattering due to the clockwise rotation of the winding drum 203. At this time, by rotating the baffle plate 4 to the side end of the side groove 206, the baffle plate 4 is pressed hard to make the elastic plug plate 401 inserted into the slot 207. At this time, the protrusion 208 presses the side end of the elastic card plate 301 to cause a certain deformation. When the protrusion 208 passes through the slot 403 at the side end of the elastic card plate 301, it no longer presses the side end of the elastic card plate 301. At this time, the elastic card plate 301 will rebound, so that the protrusion 208 is limited in the slot 403, so that the elastic card plate 301 is fixed in the slot 207, thereby completing the fixation of the baffle plate 4, so that the end of the fire hose can be limited and fixed, avoiding the situation that the fire hose is scattered.
