However, the existing electric hoist has the problem of insufficient safety. In the working process of the electric hoist, once the electric hoist is powered off, if the electric hoist is not braked in time and quickly, articles lifted by the electric hoist can descend to hit people, and safety accidents are caused. In addition, the highest limit position and the lowest limit position of the chain retraction of the electric hoist are limited by the limit switches, and when a certain limit switch is damaged or fails, the highest limit position and the lowest limit position of the chain retraction cannot be limited, so that the electric hoist is easily damaged, and accidents are caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a servo electric block of intelligence has solved current electric block and has had the not enough defect of security.
The technical scheme of the utility model is realized like this:
intelligence servo electric block, including servo driver, a relay, servo motor, the reduction gear, chain hoisting device, the chain, limit switch, encoder and electromagnetic brake stopper, servo driver passes through relay and servo motor electric connection, servo motor passes through the reduction gear and is connected with the transmission of chain hoisting device, the chain is connected on chain hoisting device, limit switch, encoder and electromagnetic brake stopper all with servo driver electric connection, limit switch sets up on chain hoisting device, limit switch is used for restricting the highest and the extreme low position of chain, electromagnetic brake stopper is outside servo motor's pivot, the encoder is connected in servo motor's pivot, the encoder is used for restricting the highest and the extreme low position of chain equally.
Further, the limit switch is a microswitch.
The utility model has the advantages that: the utility model discloses during normal circular telegram work, servo driver passes through the relay and communicates with servo motor, servo motor normally works, once when taking place the outage, electromagnetic brake stopper can hold servo motor's pivot because the outage, give servo motor brake speed reduction, until stopping, the relay disconnection is connected with servo driver and servo motor simultaneously, servo motor's coil forms short circuit connection, because servo motor's rotor is permanent magnet rotor, so produce the magnetic short circuit, give servo motor brake speed reduction equally, until stopping, reach the effect of dual speed reduction brake, guarantee that electric block when the outage, can in time, the quick electric block of stopping, prevent to take place the incident; additionally, the utility model discloses on limit switch's basis, increased the encoder, in case limit switch breaks down, the encoder can also play a role, reaches the effect of the highest and the extreme lower position of restriction chain, and dual assurance safety prevents to damage electric block and emergence accident.
