Control technology, already close to maturation, the most all uses the elevator automatically controlled.
But now elevator also has its incomplete one side, as elevator occurs that toll bar, rope are out of control etc., especially rope
Out of control, can make the car drastically to decline when car is positioned at high level in elevator, the safety of passenger in serious harm car, therefore
Just need badly on market and a kind of can additionally assist the device preventing car from excessively clashing into.
Utility model content
The technical problems to be solved in the utility model is to provide one and can reduce when elevator rope dramatic decrease out of control
The device that car clashes into.
In order to solve the problems referred to above, embodiment of the present utility model proposes buffer unit bottom a kind of lift car, bag
Including balancing weight, steel wire rope and car, one end of described steel wire rope is arranged at car, and the other end of described steel wire rope is arranged at counterweight
Block, is additionally provided with drivewheel and driven pulley in the middle of described steel wire rope, described drivewheel is provided with the first motor, described driven
Being provided with encoder on wheel, described encoder is connected to master controller by encoder-driven module, and described cage bottom is arranged
Have upper backup pad, the bottom surface of described upper backup pad to be provided with towed electric magnet and compression spring, described towed electric magnet and
The lower end of compression spring is provided with lower supporting plate.
Wherein, described towed electric magnet and compression spring are arranged in pairs, and are distributed in the surrounding position below upper backup pad.
Wherein, described master controller is arranged in control chamber, and described master controller is also associated with crystal oscillator module, reseting module
And alarm module.
Wherein, described control chamber is arranged at installing plate.
Wherein, described drivewheel and driven pulley be provided with the groove for making steel cable sliding, described drivewheel and from
The axis of driving wheel is located in the same horizontal plane.
Wherein, described first motor uses DC Brushless Motor.
Wherein, described master controller is 51 series monolithics.
Having the beneficial effect that of technique scheme of the present utility model:
In such scheme, this utility model proposes buffer unit bottom a kind of lift car, by the setting of encoder,
The rotating speed of driven pulley can be detected easily, and then by encoder-driven module, the numerical value recorded is sent to main control
Device, master controller judges that encoder is passed the threshold values that the size of numerical value sets with it back and compared, the threshold values such as larger than set, then
Think that cage descending exceeds the speed limit, then control towed electric magnet and stretch, and then drive the flexible of compression spring, thus make lower support
Distance between plate and upper backup pad increases, when car being collided under the common effect of lower supporting plate and upper backup pad, and can
To absorb the impact force of car to a greater degree, ensure the safety of passenger, it is achieved that Automatic Control.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
As shown in Figures 1 to 4, embodiment of the present utility model discloses buffer unit bottom a kind of lift car, including
Balancing weight 1, steel wire rope 2 and car 12, one end of described steel wire rope 2 is arranged at car 12, and the other end of described steel wire rope 2 is arranged
In the middle of balancing weight 1, described steel wire rope 2, it is additionally provided with drivewheel 3 and driven pulley 6, described drivewheel 3 is provided with first electronic
Machine 14, described driven pulley 6 is provided with encoder 13, and described encoder 13 is connected to main control by encoder-driven module 18
Device 15, is provided with upper backup pad 10 bottom described car 12, the bottom surface of described upper backup pad 10 is provided with towed electric magnet 8 He
Compression spring 9, the lower end of described towed electric magnet 8 and compression spring 9 is provided with lower supporting plate 7.
Further, described master controller 15 is arranged in control chamber 5, and described control chamber 5 is arranged at installing plate 4, described
Master controller 15 is also associated with crystal oscillator module 16, reseting module 17 and alarm module 19.Described crystal oscillator module 16 is so that lead
Controller 15 produces certain crystal oscillator frequency, uses for master controller 15 internal clocking and intervalometer.Described reseting module 17
For making when master controller 15 breaks down, can return to original state, described alarm module 19 can work as encoder
13 detect that car 12 sends alarm sound when declining hypervelocity, remind staff.
