The mechanism achieving the function of rollback when accounting resistance has high flexibility and best security, controls the counter-rotating of the motor through the controller when accounting resistance, has fast rollback, can effectively prevent the motor from going wrong by fast rollback, can further avoid the condition of infrared error induction, and can effectively protect equipment and personal safety.
Description
Technical field
The utility model relates to a kind of electromechanical structure, especially a kind of mechanism of the rollback function that realizes being hampered.
Background technology
Play the effect of protection equipment and personal safety when in people's productive life, often needing at present the device of some rollbacks that are hampered that equipment is run well again; such as on the stop of field of traffic; when moving from top to bottom, runs into when hindering lever; the function that the rollback that is hampered must be arranged; one can protect car lug not to be damaged; the more important thing is and guarantee the central personal safety of car lug operation; the air bag switch is installed or is detected pin whether touch the obstruction rollback function that realizes being hampered but generally uses on the car lug at present on pin at car lug front and back installation infrared rays; effect is barely satisfactory; because it is difficult to the sensitivity and the safety that reach higher the structures shape of air bag switch itself; infrared detection then is easy to cause false sense to answer; thereby influence the normal operation of car lug, buried certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of highly sensitive for the deficiency that solves above-mentioned technology, accuracy height, the mechanism of willing a kind of rollback function that realizes being hampered.
In order to achieve the above object, the mechanism that designed a kind of of the utility model realizes being hampered the rollback function, it mainly comprises motor, transmission device and controller, transmission device is connected with drive of motor, controller is electrically connected with motor, the motor shaft of described motor is provided with speed measuring device, and speed measuring device is connected with controller signals.Speed measuring device can be measured the rotating speed of motor shaft and give controller with measurement feedback, motor rotational shaft speed just can reduce when running part is run into resistance, controller just can send reverse signal when rotating speed drops to setting value, make the motor counter-rotating, realize the rollback function, controller can be PLC, single-chip microcomputer or other smart machine.Described speed measuring device can be a velocity sensor, as the dc generator that tests the speed, tacho-alternator etc.Described speed measuring device can also be the measure speed gears that is fixedly connected on the motor shaft, reach the photoelectrical coupler that is used with measure speed gears, the gear teeth of described measure speed gears stretch into the luminous point coupler and detect in the groove, the gear revolution is crossed a tooth will produce the process of " blocking-printing opacity " in detecting groove, can measure the rotating speed of motor shaft thus.Described controller can be electrically connected with motor by contactor, by the control of contactor being realized the rotating of motor.
Therefore and the fault that produces the mechanism of the resulting a kind of rollback function that realizes being hampered of the utility model is highly sensitive, and safety is splendid, and by the counter-rotating of controller control motor, rollback is rapid when being hampered, and can prevent effectively that motor.The situation that can avoid the infrared rays false sense to answer can effectively be protected equipment and personal safety again.

The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the mechanism of the described a kind of rollback function that realizes being hampered of present embodiment, it mainly comprises motor 1, transmission device 2 and controller, transmission device 2 is in transmission connection with motor 1, controller is electrically connected with motor 1, the motor shaft 4 of motor 1 is provided with speed measuring device 5, speed measuring device 5 is connected with controller 3 signals, controller 3 is PLC, speed measuring device 5 is velocity sensors 6, the output of velocity sensor 6 is connected with the analog quantity input port of PLC, and the digital quantity output 9 earthing contactors of PLC are electrically connected with motor 1.
Shown in Fig. 2,3, the mechanism of the described a kind of rollback function that realizes being hampered of present embodiment, be to change the speed measuring device among the embodiment 5 into be fixedly connected on the motor shaft 4 measure speed gears 7, reach the photoelectrical coupler 8 that is used with measure speed gears 7, the gear teeth 71 of measure speed gears 7 stretch into the luminous point coupler and detect in the groove 81, the gear revolution is crossed gear teeth 71 will produce the process of " blocking-printing opacity " in detecting groove 81, can measure the rotating speed of motor shaft 4 thus.
As shown in Figure 4, the mechanism of the described a kind of rollback function that realizes being hampered of present embodiment, it applies on the car lug, car lug mainly comprises lever 10 and pedestal 11, pedestal 11 is provided with the mechanism 12 of the rollback function that realizes being hampered, and the mechanism 12 of the rollback function that realizes being hampered is in transmission connection with lever 11, when pin 11 does not meet obstructions, the rotating speed of motor 1 just often, controller 3 control motors 1 are just changeing, and pin 11 normally moves; When pin 11 meets obstructions, motor 1 speed drop is low to moderate when setting value, 1 counter-rotating of controller 3 control motors, thus realize the pin 11 rollback function that is hampered.
