Abstract
The utility model belongs to the technical field of bridge cranes and particularly relates to a bridge crane vehicle door electromagnetic safety lock. The safety lock is characterized by comprising a position sensor, an electrometric lock, an indicating lamp and an intermediate relay, wherein the position sensor is arranged at the linking position of a bridge crane vehicle door with a platform for getting on and off, the electrometric lock is arranged on the bridge crane vehicle door, the indicating lamp is arranged inside a bridge crane driving cab, and the intermediate relay is respectively connected with the position sensor, the electrometric lock and the indicating lamp. The safety lock has the advantages of simple structure, high safety and capabilities of effectively preventing a bridge crane to be parked at unsafe on and off positions, and ensuring personal safety of operating staff.
Description
Technical field
The utility model belongs to the crane in bridge type technical field, particularly a kind of crane in bridge type car door abampere full lock.
Background technology
Crane in bridge type is the visual plant during enterprise produces, because its aloft work is classified as enterprise's special safety emphasis equipment by country, safety is particularly important.Usually after the crane in bridge type safety that must be parked in appointment gets on and off the position, just can open its door lock.And the door lock of crane in bridge type is simple and easy mechanical pin, no matter which position crane in bridge type rests on, crane driver can be opened door.Certain mining company once took place to specify the safety position of getting on or off the bus because crane driver is parked in crane in bridge type, just opened student's car, caused the high-altitude fatal accident of falling.Therefore press for a kind of safe crane in bridge type door lock.
Summary of the invention
The purpose of this utility model provides a kind of crane in bridge type car door abampere full lock of simple in structure, high safety.
The purpose of this utility model realizes by following technical proposals:
A kind of crane in bridge type car door abampere full lock of the present utility model, it is characterized in that by being located at the position transduser of crane in bridge type car door with the platform joining place that gets on and off, be located at the electromagnetic lock on the described crane in bridge type car door, be located at the indicator lamp in the described Vibration Acceleration on Bridge Crane Cab, the intermediate relay that is connected with described position transduser, electromagnetic lock and indicator lamp is formed respectively.
The characteristics of crane in bridge type car door abampere full lock of the present utility model are:
Partly form by position transduser and actuating unit and indicator lamp three.When crane in bridge type moved, position transduser was not at induction zone, and the sensor output point disconnects, the intermediate relay outage, and indicator lamp goes out, electromagnetic lock outage door lock is dead.When having only cart to get back to get on and off platform sensor sensing district, sensor output point closure, intermediate relay gets electric, indicator lamp is bright, electromagnetic lock get electric after, car door just can be opened, and guarantees that personal security gets on or off the bus.Indicator lamp is installed to the place that is easy to driver observation in the operator's compartment, thereby hoisting crane is stopped to assigned address.
The utility model is simple in structure, and high safety can effectively avoid crane in bridge type to stop in the non-safety position that gets on and off, and has guaranteed the personal safety of operating personal.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Given embodiment further specifies the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of crane in bridge type car door abampere full lock of the present utility model, it is characterized in that by being located at the position transduser 2 of crane in bridge type car door with the platform joining place that gets on and off, be located at the electromagnetic lock 5 on the described crane in bridge type car door, be located at the indicator lamp 4 in the described Vibration Acceleration on Bridge Crane Cab, the intermediate relay 3 that is connected with described position transduser 2, electromagnetic lock 5 and indicator lamp 4 is formed respectively.
The principle of work of crane in bridge type car door abampere full lock of the present utility model is:
When crane in bridge type is parked in safety when getting on or off the bus platform, position transduser 2 closings of contact, intermediate relay 3 electric, intermediate relay 3 open contact closures, indicator lamp 4 is bright, electromagnetic lock 5 electric, car door just can be opened.When crane in bridge type moves away when getting on or off the bus platform 1, position transduser 2 contact opens, intermediate relay 3 outages, intermediate relay 3 open contacts are opened, and indicator lamp 4 outages, electromagnetic lock 5 outages are on the Door Lock.
The utility model is simple in structure, and high safety can effectively avoid crane in bridge type to stop in the non-safety position that gets on and off, and has guaranteed the personal safety of operating personal.
