Abstract
The invention relates to a safe lock for lifting of an elevator car. The safe lock for lifting of the elevator ca, provided by the invention, comprises an elevator car body 1, lock frames 2, lock heads 3, snap close plates 4 and disconnecting link operating mechanisms 5, and is characterized in that the lock frames 2 are arranged in the elevator car body 1; the lock heads 3 are arranged on the lock frames 2; one disconnecting link operating mechanism 5 is arranged on a doorframe at the entrance/exit of an elevator at each floor; the snap close plates 4 are arranged on connecting rods of the disconnecting link operating mechanisms 5. The safe lock is simple in structure and relatively low in production cost and has the function of guaranteeing the safety of passengers, and personal casualty caused when the elevator car is accidentally out of control in lifting is prevented.
Description
Technical field
The present invention relates to a kind of lift car elevating safety lock, especially a kind of lift car elevating safety lock with protection lift car passenger security function.
Background technology
Existing lift car does not arrange the elevating safety lock of protection passenger security function, causes injures and deaths as car is surprisingly elevated not stop passenger to be blocked.Restaurant, shaba District one, 02 month Chongqing on the 08th in 2009 baggage elevator has an accident suddenly, and car lands vertically to negative second floor from flat street floor, so that restaurant one room attendant unfortunately falls dead, and accident causation is caused by baggage elevator lifting cable breaks.In morning on October 7th, 2012, the elevator burst on building ground, agglomerate town one, Pudong New District is unexpected, and the Anhui nationality woman of 48 years old is stuck in 6 upstairs, causes that it is dead then and there.On September 14th, 2014, at dusk, in an elevator of school district, Huaqiao University Xiamen Main Teaching Building C4, boy student did not surprisingly stop to be died in car by mounting board due to car.
The invention being 02816712.0 as number of patent application relates to a kind of safety guard from car top maintenance of elevator systems, and this patent is on car top region, be fixed with a vertical column.In one embodiment, the clamp load that cylinder can bear is greater than the disengaging load of car drive mechanism.In another embodiment, a safety is girdled the waist and is connected to the near top of cylinder by a hawser; The vertical column of this application is arranged on car top region, and object protects the staff stood on traction drive elevators top, instead of protect the safety of passenger in lift car; And this application does not solve the problem that the unexpected lifting out of control of lift car can cause casualties.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of lift car elevating safety lock, can prevent the unexpected lifting out of control of lift car from can cause casualties, there is protection passenger security function.
Its technical scheme is: a kind of lift car elevating safety lock, comprise car 1, lock frame 2, tapered end 3, locking board 4, switch operation mechanism 5, it is characterized in that: described lock frame 2 is arranged in car 1, described tapered end 3 is arranged on lock frame 2, described switch operation mechanism 5 is arranged on the doorframe of each floor elevator gangway, described locking board 4 is arranged on the connecting rod of switch operation mechanism 5, and described tapered end 3 is identical with the floor level of each floor of distance of locking board 4 apart from the height on car 1 ground.
As optimization, a kind of lift car elevating safety lock of the present invention, is characterized in that: when elevator lifting is to each floor, and it is closed that described tapered end 3 can reach the locking board 4 of each floor elevator gangway from car 1.
As optimization, a kind of lift car elevating safety lock of the present invention, is characterized in that: described tapered end 3 connecting power line, forms electromagnetic lock with lock frame 2, locking board 4, switch operation mechanism 5.
As optimization, a kind of lift car elevating safety lock of the present invention, is characterized in that: doorframe and the floor building of described floor elevator gangway link together; When tapered end 3 closes from the locking board 4 that car 1 reaches each floor elevator gangway, the doorframe of floor elevator gangway can bear elevator and surprisingly be elevated produced load.
Principle of work of the present invention: when lift car be elevated to each floor open elevator door time, hook 2 from car 1 reach catch among the ring 3 of each floor elevator gangway stable, can prevent the unexpected lifting out of control of lift car, such people just can pass in and out safely elevator (car); Solve the problem that the unexpected lifting out of control of existing lift car can cause casualties.
Advantage of the present invention: 1, have protection passenger security function, can solve the problem that the unexpected lifting out of control of lift car can cause casualties.2, simple structure, productive costs is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: car 1, lock frame 2, tapered end 3, locking board 4, switch operation mechanism 5.
Detailed description of the invention
Below embodiments of the invention are described in detail by reference to the accompanying drawings.
Embodiment 1: as shown in Figure 1, a kind of lift car elevating safety lock, comprise car 1, lock frame 2, tapered end 3, locking board 4, switch operation mechanism 5, it is characterized in that: described lock frame 2 is arranged in car 1, described tapered end 3 is arranged on lock frame 2, described switch operation mechanism 5 is arranged on the doorframe of each floor elevator gangway, described locking board 4 is arranged on the connecting rod of switch operation mechanism 5, and described tapered end 3 is identical with the floor level of each floor of distance of locking board 4 apart from the height on car 1 ground.
