Compared with prior art, this utility model has beneficial effect highlighted below:
1, this utility model is provided with base plate, and described base plate can cover above tunnel, it is prevented that staff, when opening and closing fire valve, due to work carelessness, falls in tunnel；
2, this utility model is rotated by worm and gear band wrench pawl, easy to use, simple to operate。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated。
As it is shown in figure 1, this utility model includes bracing frame 2, worm gear 7, worm screw 12, sleeve 8, interior bar 10, spanner pawl 3 and leading screw 5。
Described bracing frame 2 is provided with through hole, the described through hole on sleeve 8 traverse bracing frame 2 and bracing frame 2 are for being rotatably connected, described sleeve 8 is provided with hexagon through hole, described interior bar 10 is in hexagon and the hexagon through hole being embedded in sleeve 8, one end of described interior bar 10 is connected with spanner pawl 3, the other end is connected with one end of connecting rod 9, and one end of the other end of connecting rod 9 and connecting plate 11 is for being rotatably connected。
Described bracing frame 2 is provided with otic placode, described otic placode is provided with through hole, the through hole on otic placode is passed with otic placode for being rotatably connected in one end of described leading screw 5, the other end and first rocking bar 4 of leading screw 5 connect, the other end of described connecting plate 11 is provided with a screwed hole, and the described screwed hole on connecting plate 11 is threadeded with leading screw 5。When rotating the first rocking bar 4, the first rocking bar 4 drives leading screw 5 to rotate, and leading screw 5 rotates and interior bar 10 can be driven to move along the hexagon through hole of sleeve 8 by connecting rod 9。
Described sleeve 8 is connected with the centre bore of worm gear 7, described bracing frame 2 and the two ends of worm screw 12 are for being rotatably connected, described worm gear 7 is meshed with worm screw 12, the two ends of described worm screw 12 are connected with the centre bore of driven sprocket 6, described bracing frame 2 and rotates the two ends of axle for being rotatably connected, the described two ends rotating axle connect through the through hole on bracing frame 2 and the second rocking bar 14, the described axle that rotates is connected with the centre bore of drive sprocket 15, and described drive sprocket 15 is connected by chain 13 with driven sprocket 6。
The lower end of described bracing frame 2 is connected with base plate 1, and described base plate 1 is provided with a large through-hole, and the large through-hole of described base plate 1 is just to spanner pawl 3, and the diameter of base plate 1 large through-hole is more than the size of spanner pawl 3。
Operating process is as follows: when using this utility model, this utility model is placed on the top in tunnel, the just handle to fire valve by the through hole on base plate 1。Rotating the first rocking bar 4, the first rocking bar 4 drives leading screw 5 to rotate, and leading screw 5 rotates and interior bar 10 can be driven to move along the hexagon through hole of sleeve 8 by connecting rod 9, thus band wrench pawl 3 moves。When spanner pawl 3 arrives the handle position of fire valve, rotate the second rocking bar 14, second rocking bar 14 drives drive sprocket 15 to rotate, drive sprocket 15 drives driven sprocket 6 to rotate, driven sprocket 6 drives worm screw 12 to rotate, and worm screw 12 drives worm gear 7 to rotate, and worm gear 7 rotates band moving sleeve 8 and rotates, sleeve 8 rotates band wrench pawl 3 and rotates, thus driving the handle of fire valve to rotate。
It should be noted that; this utility model has been described in detail by particular of the present utility model; for a person skilled in the art, the various apparent change when without departing substantially from spirit and scope of the present utility model, it carried out is all within protection domain of the present utility model。
