Abstract
The utility model relates to an anti-falling device for a mobile cab of a gantry crane, and mainly solves the technical problem of preventing a driver opening the door in the air after the cab leaves an operating platform. The technical scheme adopted by the utility model is that the anti-falling device for the mobile cab of the gantry crane comprises a safety protective barrier, a metal proximity switch, a travel switch and a voice alarm, wherein the metal proximity switch is arranged behind the right side at the top of the cab and corresponds to a positioning metal plate fixed above the operating position; the rotatable safety protective barrier is arranged in the door of the cab; the travel switch is mounted at the locking part of the movable end of the barrier, and a locking pin is arranged at the locked end; and the voice alarm is mounted on the wall surface at the rear part of the cab. The anti-falling device is mainly used for preventing personal injury accidents because the driver falls to the ground from the cab when unconsciously opening the cab door of the crane after the mobile cab leaves the operating platform of the driver.
Description
Technical field:
The utility model relates to a kind of gantry mobile driver's cab falling proof device of driving a vehicle that is applicable to.Be mainly used in and prevent that the removable driver's cab of driving a vehicle from sailing out of on the driver behind the machine platform position, the unconscious cab door of opening of driver causes personnel from driver's cab Crater face, causes personal injury accident to take place.
Background technology:
Bearing the open-air Ku Chang of finished product wharf gantry driving of hot-rolled product transhipment task.Because the driving span reaches 35 meters, therefore driver's cab walking manner has voluntarily been adopted in driving in design, adjusts the driver's cab stop place voluntarily according to hanging the object location driver, is convenient to driver observation and hangs thing and realize handling efficient the best.But because driver's cab aisle outside design is not provided with the time, and press the hoisting crane standard, cab door must be to outward swinging door, cause when driver's cab and leave seat in the plane postpone, open cab door, what face will be the dangerous circumstances of uphanging in midair, very easily cause personnel's falling accident to take place.Therefore, how to avoid that the driver unconsciously opens cab door when driver's cab hangs in midair, prevent the urgent problem that becomes of high-altitude falling accident.
The utility model content:
The purpose of this utility model provides a kind of gantry mobile driver's cab falling proof device of driving a vehicle that is applicable to, mainly solves driver's cab and leaves the technical matters that how to stop the driver to open the door in midair behind the machine platform position.
The technical solution of the utility model is: a kind of gantry mobile driver's cab falling proof device of driving a vehicle comprises that safe protective railing, metal are near switch, travel switch, phonetic alarm.Described metal is placed in driver's cab top right rear near switch, and the location metal sheet of putting upper fixed with last seat in the plane is corresponding; Establish rotating safe protective railing in the cab door, travel switch is installed in locking place of railing movable end, and keyed end is provided with stop pin; On the metope of driver's cab rear portion, phonetic alarm is installed.
The warning circuit of described phonetic alarm is that annunciator is connected in series the back power connection with metal successively near switch, travel switch.
The beneficial effects of the utility model are: when driver's cab leaves the machine platform position, and when the driver opens the rotatable end of safe protective railing, the phonetic alarm power supply is switched on, phonetic alarm sends warning, the warning driver further opens the danger that cab door exists, thereby the behavior that stops the driver further to open cab door takes place, and avoids personnel that falling accident takes place.
Description of drawings:
Fig. 1: gantry driving driver's cab site plan
Fig. 2: the utility model structural representation
Fig. 3: the utility model warning circuit figure
Among the figure: 1. metal is near machine platform 5. staircases 6. phonetic alarms 7. travel switches 8. stop pins 9. safe protective railings 10. cab doors on the switch 2. driver's cabs 3. location metal sheets 4.
The specific embodiment:
With reference to Fig. 1, a kind of gantry mobile driver's cab falling proof device of driving a vehicle is made of near switch 1, travel switch 7, phonetic alarm 6 etc. safe protective railing 9, metal.Device is placed in driver's cab 2, and driver's cab 2 is hanging connected on the frame by roller, is fixed with machine platform 4 on the column of frame one side, and the driver enters machine platform by staircase 5.
With reference to Fig. 2,3, this device driver's cab 2 whether be in the driver go up machine platform 4 positions adopt metal near switch 1 as detecting element, be installed in the right abaft at driver's cab top, the location metal sheet 3 of putting upper fixed with last seat in the plane is corresponding; Establish rotating safe protective railing 9 in the cab door, travel switch 7 is installed in locking place of railing movable end, and keyed end is provided with stop pin 8; Phonetic alarm 6 is installed on the metope of driver's cab rear portion.
Principle of work: 1, go up chamber, machine platform 4 position when driver's cab is in the driver, there is last machine platform 4 outside of cab door, the potential safety hazard that does not exist personnel to fall, this moment, the metal at driver's cab top was approaching with the location metal sheet 3 of its top near switch 1, metal is closed near switch 1, no matter the safe protective railing 9 in the driver's cab opens or closes, phonetic alarm 6 is not all sounded.
2, after driver's cab leaves last machine platform 4 positions of driver, the metal at driver's cab top near switch 1 away from its top location metal sheet 3, metal is connected near switch 1, if this moment, safe protective railing 9 was not closed locking, then phonetic alarm 6 can be reported to the police always, after the driver closed locking with safe protective railing 9, the travel switch 7 of safe protective railing 9 lockings place was closed alarm release.
3, after driver's cab leaves the driver and goes up machine platform 4 positions,, must open safe protective railing 9 earlier and just can go to open the door if the driver looks on the bright side of things (production time has been grown the driver and forgotten the present position sometimes) during cab door 10 in that operation gap is unconscious.Remove the stop pin 8 of safe protective railing 9 as the driver after, the travel switch 7 of safe protective railing 9 lockings place is opened, phonetic alarm 6 is not connected before cab door 10 is opened, send voice warning, the warning driver danger of opening the door, stop driver's generation of behavior of opening the door, thereby avoiding personnel to open the door causing personal injury accident from falling in midair takes place.
