Wherein preferred version is:
It is rack-mount that the wheel shaft two ends of described track adjusting wheel are provided with bearing fixing respectively.Install and fix, guarantee stable, the efficient height.
The rotating shaft of described anti-falling safety device can have multiple with the connection mode of wheel shaft: be connected by gear mesh, rotating shaft is provided with miniature gears, and wheel shaft is provided with big gear wheel, big gear wheel and pinion transmission.By the engaged transmission of big gear wheel and miniature gears, adjustable transmitting ratio is provided, make anti-fall safer.
The rotating shaft and the wheel shaft of described anti-falling safety device are connected by sprocket wheel, and rotating shaft and wheel shaft are provided with sprocket wheel respectively, chain is set on two sprocket wheels connects.
The rotating shaft of described anti-falling safety device and wheel shaft can also be by coupler, flange, driving key or direct connection.
The connection terminal of described anti-falling safety device connects the power-supply controller of electric of traction power unit.The emergency power off function is provided, avoids accidents caused.
Described anti-falling safety device fixed position both can directly be fixed on the platform, can be fixed on the support.
The beneficial effect that the anti-fall drag device of the utility model speed limit is had is: by the other end at the wheel shaft of the track adjusting wheel of SSD building hoist the connection anti-falling safety device is set, anti-falling safety device and wheel shaft are connected and fixed by modes such as direct connection, gear mesh, sprocket wheel, coupler, flange or driving keys, when overspeed situation, anti-falling safety device can be by various type of drive, the emergency braking track adjusting wheel, safety control is provided, operates steadily, the safe reliability height.
By being provided with, use building hoist of the present utility model can:
1, the in-use performance that possesses the SSD building hoist adopts the safety anti-falling device of using in the SCD building hoist, improves safety in operation;
When 2, hypervelocity appears in track adjusting wheel, can give the alarm, and braking, the smooth operation of guarantee building hoist;
3, building hoist is operating anti-fall;
4, can realize emergency cut-off main power source under the state in danger, increase the protection effect.
