Abstract

The invention proposes an anti-falling device for an elevator, which includes a platform, a bracket arranged on the platform, a motor arranged on the bracket, a first double-chain roller, a second double-chain roller, a first tensioning wheel shaft, a second tensioning The wheel shaft, the third tensioning wheel shaft, the fourth tensioning wheel shaft, the sprockets on the first double-chain drum and the second double-chain drum respectively pass through the transmission belt and the first tensioning wheel shaft, the second tensioning wheel shaft, and the corresponding position up and down. The third tensioning wheel shaft and the fourth tensioning wheel shaft are connected, the lifting platform is set on the transmission belt strip, and the motor is connected to the first double-chain roller and the second double-chain roller; one is reliable braking, and the power signal of the second sensor Braking, once the sensor detects that the signal is out of range, the tensioning motor releases the tensioning rope, and the induction socket is engaged with the induction plug under the action of the spring, the braking device brakes, and the operation of the motor is more reliable; the second is quick response.

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a safety auxiliary device for lifts, in particular to a fall prevention device for lifts. Background technique [0002] Elevator, lifting operation platform is a multi-functional lifting mechanical equipment, which can be divided into fixed type and mobile type, guide rail type, crank arm type, scissor type, chain type, loading and unloading platform and other structural forms, used to realize cargo transportation and other functions. [0003] When the elevator is used to transport goods up and down vertically, due to equipment failure, sudden power failure and other reasons, the goods together with the lifting platform will fall vertically from a high altitude, and the falling lifting platform and goods can easily hurt the staff and even cause serious injuries. Production accidents, crisis production safety. However, factors such as equipment failure and sudden power failure are...
