Description
Technical field
The utility model relates to a kind of overhead traveling crane safety convenience instrument, is specially a kind of overhead traveling crane safety device of boarding up and down.
Background technology
Overhead traveling crane, promptly crane in bridge type is a kind of crane span structure type hoisting crane that crane span structure moves on aerial conveyor.The crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead; Crane carriage laterally moves along the track that is laid on the crane span structure; Constitute the operating range of a rectangle, just can make full use of the space handling material below the crane span structure, do not receive the obstruction of wayside equipment.Crane in bridge type is widely used in indoor and outdoor warehouse, factory building, harbour and open-air yard etc. and locates.
Overhead traveling crane will have special driver operation, and the general volume of overhead traveling crane is bigger, and the working environment compare operation, driver and the operating personal of overhead traveling crane can't effective communication up and down, and sometimes under the situation of confusing communication, the driver starts the overhead traveling crane generation that then can cause the accident
Summary of the invention
The utility model is in order to solve the technical matters that overhead traveling crane driver and the personnel of getting on or off the bus can't link up, and a kind of overhead traveling crane safety device of boarding up and down is provided.
The technical scheme of the utility model is; A kind of overhead traveling crane safety device of boarding up and down; Comprise the driver's cab contact box that is installed in the driver's cab, be installed in get on the bus the contact box and the contact box of getting off at the position of getting on or off the bus, driver's cab contact box is connected through control circuit with the contact box of getting on the bus, the contact box of getting off; Be provided with the request switch of getting on the bus in the described contact box of getting on the bus, the switch that finishes of getting on the bus, buzzer phone and indicator lamp allow to get on the bus; Be provided with the request switch of getting off in the described contact box of getting off, the switch that finishes of getting off, buzzer phone and indicator lamp allow to get off; Described driver's cab contact box is provided with asks to get on or off the bus indicator lamp and voice prompting device, indicator lamp and the relevant voice prompting device of finishing of getting on or off the bus, getting on or off the bus indicator lamp and relevant voice prompting device; Chain circuit and reset switch, the indication operating switch; Get on or off the bus indicator lamp and voice prompting device of the described request switch of getting on the bus, the request of getting off switch and request is connected; The described switch that finishes of getting on the bus is connected with finish indicator lamp and the relevant voice prompting device of getting on or off the bus with the switch that finishes of getting off; The described buzzer phone of being permitted to get on the bus with indicator lamp and the buzzer phone that allows to get off be connected with get on or off the bus indicator lamp and relevant voice prompting device with indicator lamp, connect the indication operating switch on described get on or off the bus indicator lamp and the relevant voice prompting device.
Its working process is: when the staff need go up overhead traveling crane, start the request of the getting on the bus switch in the contact box of getting on the bus, the indicator lamp of getting on or off the bus in the driver's cab contact box in the driver's cab is bright and voice suggestion arranged; The driver sees back start-up operation switch, and driver's cab contact box indicator lamp lights, and chain circuit start makes the overhead traveling crane locking simultaneously; Contact the allowing in the box of the getting on the bus indicator lamp of getting on the bus is bright; The staff gets on the bus, and starts reset switch then, overhead traveling crane work; When the staff need get off; Start the request of the getting off switch in the contact box of getting off, the indicator lamp of getting on or off the bus in the driver link box lights, after the driver obtains signal; The start-up operation switch quits work overhead traveling crane immediately; The allowing in the driver link box of the getting off indicator lamp of getting off is lighted, and the staff gets off, and the driver recovers the overhead traveling crane normal operation more then.
Compared with prior art, the utility model is simple in structure, and is reasonable in design, can make the overhead traveling crane driver can access actv. with the staff that gets on or off the bus through simple decision circuit and link up, guaranteed to get on or off the bus safety, improved production efficiency and safety.
