Abstract
The utility model discloses an electric adjusting air door used in hot air system equipment widely applied in industries, such as electrical power, chemical engineering, mine, and the like. The electric adjusting air door comprises a doorframe (1), channel steels (16) and a bracket (20), wherein an electric executor (19) is fixed at the upper end of the bracket (20) and is connected with a transmission shaft (10) by a coupling (18), and the middle of the transmission shaft (10) is movably connected with a shaft seat (17) fixed at the right part of the doorframe (1); strengthening ribs (5) are respectively fixed in the middle of a middle door panel (14), and connecting levers (3) are respectively and movably connected with the upper ends of the strengthening ribs (5) and are respectively and movably connected with an upper door panel structure and a lower door panel structure by the connecting levers (3). In the utility model, due to the straight shaft connection of an integral dry bearing and an erosion-resisting and transmission mechanism of a plate stem type, the air door is hermetically closed without leakage, is flexibly opened and closed without clamping and can be fully opened or closed without void travel. The utility model is convenient to mount, can be mounted at any angle, such as a horizontal angle, a vertical angle, and the like, is convenient to operate, is simple and convenient to maintain with little maintenance, has low cost and can satisfy the requirements of different places for safe operation and protection.
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 technique; 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 operating conditions 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.
The model utility content: 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 right lower side, described electric actuator 19 is fixed on carriage 20 upper ends, and be connected with transmission shaft 10 by coupling 18, 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, 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, stiffening rib 5 is separately fixed at middle door-plate 14 middle parts, and connecting lever 3 is movably connected in stiffening rib 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 driving mechanism connects; thereby close tight nothing and reveal, 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.
Description of drawings: Fig. 1 is a plan view of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment: as shown in Figure 1 and Figure 2, 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 right lower side that is connected triangular in shape, and electric actuator 19 is fixed on carriage 20 upper ends, and is connected with transmission shaft 10 by coupling 18, mainly plays transfer motion 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.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.Stiffening rib 5 is separately fixed at middle door-plate 14 middle parts, and connecting lever 3 is movably connected in stiffening rib 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, stiffening rib 5 is separately fixed at upper and lower door-plate 2,15 middle parts, connecting lever 3 is movably connected in stiffening rib 5 upper ends, flexibly connects with the connecting lever 3 of middle door-plate 14 respectively by connecting rod 4.
In use, start electric actuator, by coupling and 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.
