Abstract
One kind prevents elevator high-speed falling device, the utility model to be related to a kind of elevator protection field, including a metal guide rail with double wedge, the toothed metal guide rail to be vertically installed in elevator.One connecting seat is installed with metal guide rail corresponding position what elevator car the utility model provided a kind of top for preventing elevator high-speed falling, the connecting seat upper hinge formula connects an escapement.When elevator high-speed falling, the gravity of elevator car is delivered between the double wedge of metal guide rail through escapement so as to reduce lapse rate.The beneficial effect of the technical program is, simple structure, solve elevator will not high-speed falling, will not also be stuck in the air.Just in case the device failure elevator will not also fall.
Description
Technical field
The utility model is related to a kind of elevator protection field, and a kind of elevator fall arrest field is related to by it.
Background technology
At present, various falling proof devices are mounted with elevator, but due to safeguarding not in time or safeguarding improper, or because of other visitors
Seeing reason causes falling proof device failure and elevator car is fallen and happen occasionally, and causes life property to be damaged.
Publication number（CN205076600U, publication date 2016.03.09）The patent application text of " a kind of device for preventing elevator from falling "
Stung with guide rail of the surface with tooth bar using the arrestment mechanism being fixed on elevator car when part provides a kind of used during elevator falling
Elevator is suspended in aerial anti-fall device after conjunction, the device has obvious superiority relative to current anti-fall device, but
Two problems of aspect are still suffered from, one is just in case failure still has the possibility of high-speed falling, the second is arrestment mechanism is by cage
Still hung on when body is engaged on guide rail in the air, the human body still place in cage is at stake.It is therefore desirable to elevator can be made
In other anti-fall device failures, elevator car can also be down to ground with relatively slow.
The content of the invention
The technical problems to be solved in the utility model be to provide it is a kind of remain to make when other anti-fall device failures elevator with
More slow speed is down to the device on ground.
In order to solve the above technical problems, this practicality newly provide one kind remain to make when other anti-fall device failures elevator with compared with
Slow speed is down to the device on ground.Including a metal guide rail with double wedge, the toothed metal guide rail is vertically installed at
In elevator.Elevator car the utility model a kind of top for preventing elevator high-speed falling is provided with metal guide rail corresponding position
One connecting seat is installed, the connecting seat upper hinge formula connects an escapement, and the dog of the escapement matches with the double wedge of metal guide rail
Merge as elevator car movement swings.Double wedge of the escapement dog in metal guide rail is remained while swing
Between groove in, just in case the escapement failure elevator will not also fall.When elevator Normal Take-Off And Landing, the escapement is convex with metal guide rail
The resistance very little of between cog, when elevator high-speed falling, the gravity of elevator car be delivered to through escapement between the double wedge of metal guide rail from
And reduce lapse rate.In addition, fixedly mounting one piece of fixture block on connecting seat, the fixture block is stuck in metal guide rail along metal guide rail
Slide up and down, can prevent from separating before and after escapement and guide rail or shifting.
The beneficial effect of the technical program is, simple structure, solve elevator will not high-speed falling, will not also be stuck in half
In the air.Just in case the device failure elevator will not also fall.
Brief description of the drawings；
Fig. 1 is that this prevents the schematic diagram of elevator high-speed falling device
Marked in figure；The escapement of 1 elevator car, 2 metal guide rail, 3 connecting seat, 4 fixture block 5.
Specific embodiment
The metal guide rail 2 of embodiment 1 is vertically installed in elevator near elevator car, and being close to for the metal guide rail 2 is electric
Elevator car dignity is provided with uniform double wedge, and the double wedge is triangle or conical tooth.At the top of elevator car 1 near metal guide rail 2
Corresponding position fixedly mounts a connecting seat 3, and the upper end hinge type of connecting seat 3 is connected with escapement 5, the dog and metal of the escapement 5
Appropriateness distance coordinates between the double wedge of guide rail 2, makes the between cog of two dog exchange activities in metal guide rail 2 up and down of escapement 5.For
Displacement before and after preventing from occurring between escapement 5 and metal guide rail 2, is installed with one piece of fixture block 4, the one of fixture block 4 on connecting seat 3
End is fixedly connected on connecting seat 3, and the other end is stuck on guide rail 2 and is slided up and down along metal guide rail.
This embodiment is institute in the case of the preferred scheme of the technical program, all principles without departing from the technical program
The change or deformation made, or equivalent are regarded as protection domain of the present utility model.
