Summary of the invention

The technical problem to be solved in the present invention is: a kind of gate of passing by one's way that is easy to opening and closing is provided.

In order to solve the problems of the technologies described above, the present invention includes flashboard and lower shaft, the ground of building entrance is provided with lock groove, lower shaft is horizontally installed in lock groove, one side of flashboard is fixed on lower shaft, lower shaft is connected with the drive unit that drives lower shaft to rotate, and lower shaft is in rotation process, and flashboard has the two states of holding up gear and enter in building entrance bottom and horizontal lock groove.

In order to prevent the infiltration of flashboard periphery, the relative face of two abutment walls of described building entrance is smooth flat, the limit, the left and right sides of flashboard is provided with side seal bar, in the time that flashboard is holded up gear in bottom, building entrance, the side seal bar of the left and right sides of flashboard contacts with the smooth flat sealing of two abutment walls of building entrance, on lock groove, outer cell wall is provided with end weather strip, and lower shaft rolls and contacts with end weather strip.

For ease of operation, described driving mechanism comprises motor and speed reducer, and reductor connects motor, and reductor is connected with lower shaft by worm and gear, and one end of worm gear and lower shaft is fixed, and worm screw is fixedly connected with reductor, and worm and wheel is meshed.The lead angle of worm and wormwheel is less than equivalent friction angle, and therefore mechanism has self-locking performance, without separately establishing brake, can make gate in arbitrarily angled stop motion.

In order to make worm and worm gear have self-locking performance, the lead angle of described worm and wormwheel is less than equivalent friction angle.

In order to make the opening and closing of gate safer steady, described driving mechanism has two covers, is separately fixed on two abutment walls of building entrance, and two cover driving mechanisms are connected with the two ends of lower shaft by a set of described worm and gear respectively.

For the opening and closing function that can ensure gate is saved again cost, described worm gear is 90 degree worm sectors.

The invention has the beneficial effects as follows: flashboard of the present invention can spin upside down by the rotation of lower shaft, gate is in the time of opening and closing, only need to start drive unit drives lower shaft to rotate, easy to operate, be easy to opening and closing gate, the present invention can be applicable to the import flood control of the underground installations such as Urban Underground garage, supermarket, also can be applicable to retaining of middle and small river.The present invention can make vehicle, pedestrian is accessible passes through, easy to use, safe and reliable, has promotion prospect widely.

Detailed description of the invention

A kind of specific embodiment as Figure 1-4, it comprises flashboard 7 and lower shaft 5, the ground of building entrance is provided with lock groove 16, lower shaft 5 is horizontally installed in lock groove 16, and the two ends of lower shaft 5 are respectively connected with 3, two driving shafts 3 of a driving shaft by flange 4 and intert respectively in two abutment walls 6 of building entrance, in abutment wall 6, be embedded with service sleeve through walls, driving shaft 3 is inserted in wall bushing, between driving shaft and service sleeve through walls, establishes O-ring seal, and anti-sealing flows out abutment wall by gap.Abutment wall 6 is fixed with lower shaft bearing support 1 on the ground away from a side of building entrance, and one end of driving shaft 3 is arranged in lower shaft bearing support 1 by bearing, and the other end of driving shaft 3 is connected with lower shaft 5.

On driving shaft 3, be fixed with 90 degree worm sectors 2, a side away from building entrance on each abutment wall 6 is fixed with bearing support 8, bearing support 8 is provided with motor 11 and reductor 12, reductor 12 connects motor 11, on the output shaft of reductor 12, be fixed with worm screw 13, on abutment wall 6, be also provided with the worm shaft bearing 14 that supports worm screw 13, worm screw 13 is meshed with worm gear 2.

One side of flashboard 7 is fixed on lower shaft 5, and lower shaft 5 is in rotation process, and flashboard 7 has the two states of holding up gear and enter in building entrance bottom and horizontal lock groove 16.In lock groove 16, be provided with supporting base 17, in the time of flashboard 7 horizontal, flashboard 7 is supported by supporting base 17.

On the relative face of two abutment walls of building entrance, be provided with terrazzo plate or corrosion resistant plate 9, thereby formation smooth flat, this face is called flashboard running face, the limit, the left and right sides of flashboard 7 is provided with side seal bar 10, in the time that flashboard 7 is holded up gear in bottom, building entrance, the side seal bar 10 of the left and right sides of flashboard 7 contacts with the smooth flat sealing of two abutment walls 6 of building entrance, forms sealing structure for water.On lock groove 16, outer cell wall is provided with end weather strip 15, and lower shaft 5 and end weather strip 15 rolls and contact, and outerly refers to that adjacent structure outdoors.Thereby make lower shaft 5 in the time rotating, keep sealing between lower shaft 5 and lock groove 16, water can not enter lock groove 16.

The setting of side seal bar 10 and end weather strip 15 is to enter in building for better waterproof.

Motor 11 and reductor 12 also can have been adopted existing other driving mechanism and replace.
