Detailed description of the invention
Be described in detail the meticulous detent mechanism of Airshower chamber lever gear door of the present utility model referring to drawings and Examples, parts wherein same as the prior art employ identical Reference numeral.
Fig. 1 is the structural representation of the meticulous detent mechanism of Airshower chamber lever gear door of the present utility model; Fig. 2 is the annexation schematic diagram of drive mechanism of the present utility model.As depicted in figs. 1 and 2, the meticulous detent mechanism of Airshower chamber lever gear door of the present utility model, comprises motor 11, by the driving shaft 1 of motor 11 driven rotary, is arranged on the take-up pulley 2 at driving shaft 1 two ends, the fixed pulley 3 arranged above take-up pulley 2 and control circuit.Two take-up pulleies 2 realize rising and the decline of lever gear door by folding and unfolding steel wire rope 13, be connected to steel wire rope 13 on take-up pulley 2 by being connected on lever gear door after fixed pulley 3.Use fixed pulley 3 to coordinate with take-up pulley 2, folding and unfolding steel wire rope, enables door move up and down stably.
One end that driving shaft 1 is connected with motor 11 is provided with driving shaft sprocket wheel 4, the output shaft of motor 11 is connected with motor sprocket 6, is connected between motor sprocket 6 with driving shaft sprocket wheel 4 by chain 5.Motor is arranged in the motor support plate 7 that supported by the first bracing frame 8 and the second bracing frame 9, and the first bracing frame 8 and the second bracing frame 9 are provided with angle steel 12 with the junction of motor support plate 7.Driving shaft is supported by the second bracing frame 8 and the 3rd bracing frame 9, and the second bracing frame 8 and the 3rd bracing frame 9 are connected to the outside of two take-up pulleies 2, and second supports, 8 and the 3rd bracing frame 9 be also provided with angle steel 12 with driving shaft junction.Use angle steel 12 pairs of bracing frames to reinforce, can prevent bracing frame and the track be arranged in bracing frame from deforming under weight.
