Description
Technical field
The utility model belongs to a kind of safety protection device, especially a kind of safety protection driving mechanism that is used for automatic revolving door.
Technical background
Present large automatic door, automatic door are a kind of dynamic rotation gates, central core of circulation as personnel's turnover, its Security is particularly important, automatic door is in rotary course, if the pedestrian is contact-impact door body, particularly between revolving door body and fixed gate body, promptly in the shear zone between inside door head and the external door head, will certainly cause personnel are injured.For the pedestrian is carried out safety protection; should opposite house implement that the anti-collision anti-pinch is emergent to stop safety control; the driving mechanism of existing automatic revolving door; with the motor source that is used as power; rotate by output shaft of gear-box driven rotary door; when revolving door is run into the resistance of people or thing; utilize belt slippage to solve the problem that people or object are held; but, belt stops operating to order about running shaft up to the motor shutdown because skidding; need the regular hour to postpone, thus automatic revolving door to close the positional accuracy that stops poor, in addition; can produce bigger noise during belt work, and poor safety performance.
Summary of the invention
The utility model technical issues that need to address provide a kind of automatic revolving door safety protection driving mechanism, and it can overcome automatic revolving door in the prior art and close the defective that stop position is inaccurate, noise reaches poor safety performance greatly.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automatic revolving door safety protection driving mechanism, it includes drive motor and gearbox, also include induction system that is connected with the output shaft of gearbox and the clutch that is connected with the drive motor output shaft, described induction system is made up of pressure spring controlling device, shaft coupling seat, conductive hoop, lead and contact lever, the shaft coupling seat is connecting the output shaft of gearbox, and the pressure spring controlling device is located in the shaft coupling seat; The output shaft of gearbox is provided with hinge wheel, and this hinge wheel is connected with minor sprocket by Transmitted chains, on the axis of described minor sprocket break is installed.
Described pressure spring controlling device is made up of stage clip, top, follower block and position limit switch; In described gearbox, be provided with the spiral gear.
Owing to taked above-mentioned scheme, the advantage that the utility model is compared with prior art had is:
Owing to adopt the break braking, and the mode of using clutch to be separated by drive motor and rotating mechanism, improved the Safety performance of automatic revolving door, greatly reduced noise, and fundamentally solved in the prior art automatic revolving door and close the inaccurate defective of stop position.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model automatic revolving door safety protection driving mechanism;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2; the utility model automatic revolving door safety protection driving mechanism, it by drive motor 1, clutch 2, gearbox 4, the induction system that is connected with the output shaft of gearbox 4, be arranged on hinge wheel 5 on gearbox 4 output shafts, the break 6 installed on the minor sprocket 8 that is connected with this hinge wheel 5 by Transmitted chains and minor sprocket 8 axis forms.
Above-mentioned induction system includes pressure spring controlling device, shaft coupling seat 15, conductive hoop 11, lead 12 and contact lever 13; Shaft coupling seat 15 is connecting the output shaft of gearbox 4 and the centre rotational axis of automatic revolving door, described pressure spring controlling device is located in the shaft coupling seat 15, and this pressure spring controlling device is made up of stage clip 10, top 17, follower block 14 and position limit switch 9, follower block 14 is installed in the middle part of shaft coupling seat 15, one side of this follower block 14 is provided with position limit switch 9, opposite side is provided with stage clip 10 and top 17, also is provided with adjusting screw 18 at the other end of stage clip 10.
In described gearbox 4, be provided with spiral gear 3, help obtaining bigger velocity ratio and mechanical strength preferably; Be provided with bearing support 7 at break 6 and minor sprocket 8 connecting places.
The working principle and the using process of the utility model automatic revolving door safety protection driving mechanism are: by drive motor 1 as power source; through clutch 2 with power transmission to gearbox 4; the speed change of spiral gear 3 in gearbox; output shaft from the gearbox spreads out of again; drive the rotation of automatic revolving door centre rotational axis through shaft coupling seat 15; meanwhile, the also and then normal rotation of the follower block in the shaft coupling seat, revolving door runs well.
In operation process, when dodge gate is subjected to resistance, the pressure spring controlling device that is arranged in the shaft coupling seat 15 is under pressure, extruding stage clip 10, making stage clip 10 drive top 17 forces follower block 14 pivotal positions to change, the rotation of follower block 14 triggers position limit switch 9, because position limit switch 9 is connecting conductive hoop 11, the signal that position limit switch 9 sends is delivered on the main control system through conductive hoop contact lever 13 and by lead 12, send instruction to break 6 and clutch 2 by main control system, realize the disengagement of transmission shaft and drive motor, and break 6 adhesives, minor sprocket passed through, hinge wheel and shaft coupling seat make dodge gate stop the rotation rapidly, reach the effect of safe anti-collision anti-pinch, and the location is very accurate, and action does not in time have any noise.After resistance was eliminated, follower block resetted, and ordered about position limit switch again and transmitted a signal to main control system, realized that break breaks away from, and clutch connects, and made that dodge gate recovers to run well.
