Abstract
The utility model relates to an electric adjustable air door which is widely used in hot-air system devices in industry such as electric power, chemical industry, mines, etc. The utility model comprises a door frame 1, channel steel 16 and a bracket 20, wherein, a motor operator 19 is fixed at the upper end of the bracket 20 and connected with a transmission shaft 10 through a shaft coupler 18; the middle part of the transmission shaft 10 movably connected with a pressing seat fixed at the right middle part of the door frame 1 and a shaft seat 17; the top of the transmission shaft 10 is connected with a middle door plate 14 through a shaft pin 9; stiffening ribs 5 are respectively fixed at the middle part of the middle door plate 14; crank arms 3 are movably connected with the upper ends of the stiffening ribs 5 and respectively and movably connected with an upper and a lower door plate structures through connecting rods 4. Because an integral dry bearing is designed by the utility model and connected with a straight shaft of a sheet-pile wear prevention and transmission mechanism, the utility model has the advantages of tight shutting without leakage, flexible switch without blockage, full opening and full closing without idle stroke, easy installation, capability of carrying out installation at horizontal angles, perpendicular angles, etc., convenient operation, simple and convenient maintenance, small maintenance amount and low cost; the utility model can satisfy the requirements of safe operation and protection in different places, so the utility model has wide market prospects.
Description
Technical field: the utility model relates to a kind of motorized adjustment air door of using in the industry hot-air system equipment such as electric power, chemical industry, mine of being widely used in.
Background technology; Along with the high speed development of electric utility, the use of air door also more and more widely simultaneously also requires air door can adapt to conditions of work such as wind speed is fast, blast is high, wind-warm syndrome height.Old-fashioned air door is because the structure imperfection; under the effect of high temperature and hot blast pressure reduction; easy deformation, jam, open motionless, fit badly, major defect such as easy to wear; particularly there is the serious phenomenon that leaks outside; cause maintenance workload big; the difficulty height can not satisfy safe operation of the boiler and protection requirement, seriously perplexs the development of China's electric utility.
Summary of the invention: the utility model provides a kind of tight nothing leakage of closing, and switch does not have jam flexibly, and is easy to operate, keeps in repair the motorized adjustment air door that uses in the easy hot-air system equipment.It comprises doorframe 1, channel-section steel 16 is connected doorframe 1 both sides, carriage 20 is connected doorframe 1 lower right side, described YE 19 is fixed on carriage 20 upper ends, and be connected with power transmission shaft 10 by shaft coupling 18, power transmission shaft 10 middle parts and the wedge 13 that is fixed on doorframe 1 right middle, sealing gasket 11 and gland 12 and axle bed 17 flexibly connect, power transmission shaft 10 tops are connected with middle door-plate 14 by pivot pin 9, in the other end of door-plate 14 by the fixing semiaxis 7 of pivot pin 6, flexibly connect with axle bed 17, reinforcement 5 is separately fixed at middle door-plate 14 middle parts, and connecting lever 3 is movably connected in reinforcement 5 upper ends, and passes through connecting rod 4 respectively with last, following door panel structure flexible connection is formed.Because the utility model has designed integrated dry type bearing; the d-axis of plate stem formula abrasionproof and transmission mechanism connects, thereby closes tight nothing and reveal, and switch does not have jam flexibly; the completely open and close no-idle running; easy for installation, can carry out level, vertical etc. install at any angle, and easy to operate; keep in repair easy and measure little; expense is low, can satisfy the safe operation and the protection requirement of different places, thereby have good social benefit and economic benefit.
Description of drawings: Fig. 1 is a front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment: shown in Figure 2 as Fig. 1, doorframe 1 is welded by steel plate, and channel-section steel 16 and axle bed 17 are fixedly connected on doorframe 1 both sides, play the movable supporting door panel structure.Carriage 20, material are steel plate, doorframe 1 lower right side that is connected triangular in shape, and YE 19 is fixed on carriage 20 upper ends, and is connected with power transmission shaft 10 by shaft coupling 18, mainly plays transfer motion power.Power transmission shaft 10 middle parts flexibly connect with the wedge 13, sealing gasket 11 and the gland 12 that are fixed on doorframe 1 right middle and axle bed 17, mainly play a part to connect and sealing.Power transmission shaft 10 tops are connected with middle door-plate 14 by pivot pin 9, and the other end of middle door-plate 14 mainly act as door-plate and transmission in the flexible connection by fixedly semiaxis 7 and axle bed 17 flexible connections of pivot pin 6.Reinforcement 5 is separately fixed at middle door-plate 14 middle parts, and connecting lever 3 is movably connected in reinforcement 5 upper ends, and flexibly connects with upper and lower door panel structure respectively by connecting rod 4.Upper and lower door panel structure, by upper and lower door-plate 2,15, material is a steel plate, shape is rectangle, by pivot pin 6 fixedly semiaxis 7 in both sides, and and axle bed 17 flexibly connect, reinforcement 5 is separately fixed at upper and lower door-plate 2,15 middle parts, connecting lever 3 is movably connected in reinforcement 5 upper ends, is movably connected to form with the connecting lever 3 of middle door-plate 14 respectively by connecting rod 4.
In use, start YE, by shaft coupling and power transmission shaft, door-plate rotarily opens in the drive, and cross connecting rod respectively with the connecting lever of upper and lower door-plate, drive upper and lower door-plate and rotarily open and get final product.Operation is with above program when closing.
