Description
Technical field
The present invention relates to elevator accessory technical field, machine-room-less speed limiter is controlled more particularly, to a kind of remote-operable.
Background technology
Elevator governor is one of safety con-trol part in elevator safety protection system.When elevator in operation no matter what
Planting reason makes car exceed the speed limit, or even the danger fallen, and the inoperative situation of every other safety guard
Under, linkage action occurs for limiter of speed and safety tongs, stops lift car.However, common elevator governor is operationally not
Enough steady, claw and ratchet are easy to collide and produce abnormal sound.Meanwhile, it is handling not good.
The content of the invention
The deficiency existed for above-mentioned prior art, machine room is controlled it is an object of the invention to provide a kind of remote-operable
Limiter of speed, it, which has, is easy to operation, the characteristics of easily controllable, responsiveness is more stable.
To achieve these goals, the technical solution adopted in the present invention is：Remote-operable controls machine-room-less speed limiter,
Including chassis, ratchet is provided with the middle part of the chassis, and have an avris that the ratchet is articulated in the middle part of one and the ratchet that matches of the ratchet,
The bottom on the chassis is provided with an electromagnet that can be horizontally slipped, and the electromagnet is furnished with controller；
The left of the electromagnet is provided with the middle part of one first trigger board, first trigger board and is articulated on the chassis, and
The lower end of first trigger board and the left side of the electromagnet match, and the upper end of first trigger board is connected to one second trigger board
It is articulated in the middle part of upper end, second trigger board on the chassis, and the lower end of second trigger board connects the upper end of the ratchet；
The right of the electromagnet is provided with the middle part of a restoring board, the restoring board and is articulated on the chassis, the restoring board
Upper end is connected with a lobe plate, meanwhile, the bottom of the ratchet is provided with a detent pin, and the other end of the lobe plate connects the ratchet
Pin.
After said structure, the invention has the advantages that compared with the prior art,：Be easy to operation, it is easily controllable,
Responsiveness is more stable.The remote-operable control machine-room-less speed limiter of the present invention controls electromagnet or so to move by controller
It is dynamic.After electromagnet is moved to the left, it can touch after the first trigger board, it can be made to block ratchet with coupled ratchet finally makes rope sheave
It can not rotate, then stop the action that car is moved down；After electromagnet moves right, restoring board can be touched, spine is finally driven
Pawl departs from from ratchet, and car can be run again.Because controller can be manipulated using various ways, such as, pass through
The modes such as remote control, so structure is relatively simple, it is more convenient to manipulate.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the front view of embodiments of the invention.
In figure：
10th, chassis；
21st, ratchet, 22, ratchet, 221, detent pin；
30th, electromagnet, 31, controller；
41st, the first trigger board, the 42, second trigger board；
51st, restoring board, 52, lobe plate；
60th, rope sheave.
Embodiment
Embodiment, as shown in Figure 1：Remote-operable controls machine-room-less speed limiter, including chassis 10, and the middle part of chassis 10 is set
There is the rope sheave 60 that can be rotated, the rope sheave is coaxially fixed or is in linkage with a ratchet 21.That is, can be true after the ratchet 21 rotation
The car for protecting elevator is moved up and down；After ratchet 21 can not rotate, i.e., the safety tongs of elevator can be made to block guide rail, make car can not
Action.Meanwhile, the middle part for having the ratchet 22 of one and the ratchet 21 matching is articulated in the avris of the ratchet 21.That is, the energy of ratchet 22
Enough rotations, when the lower end that the ratchet 22 rotates the then ratchet 22 is stuck on the ratchet 21, the rope sheave 60 can not go rotation again
Turn.
Further say：
The bottom on the chassis 10 is provided with an electromagnet 30 that can be horizontally slipped, and the electromagnet 30 is furnished with controller 31.Should
Controller 31 can use a variety of common controllers.In the present embodiment, the controller 31 is connected with red, blue, black three colo(u)r streak, when
When red line and black line energization, the controller 31 controls the electromagnet 30 to be moved to the left, when blue line and black line energization, the controller
31 control the electromagnet 30 to move right.Certainly, the controller 31 can also use remote control.
The left of the electromagnet 30 is provided with one first trigger board 41.The middle part of first trigger board 41 is articulated in the chassis 10
On, and the lower end of first trigger board 41 and the matching of the left side of the electromagnet 30.That is, after the electromagnet 30 is moved to the left, it can make
The lower end of first trigger board 41 is moved to the left.The upper end of first trigger board 41 is connected to the upper end of one second trigger board 42.
The middle part of second trigger board 42 is articulated on the chassis 10, and the lower end of second trigger board 42 connects the upper of the ratchet 22
End.That is, after the lower end of first trigger board 41 is moved to the left, the upper end of first trigger board 41 moves right, drive this second
The upper end of trigger board 42 is moved right, and the lower end of second trigger board 42 is moved to the left, and the upper end of the ratchet 22 is moved to the left, most
The lower end of the ratchet 22 moves right and blocks the ratchet 21 eventually.
The right of the electromagnet 30 is provided with a restoring board 51.The middle part of the restoring board 51 is articulated on the chassis 10, and this is answered
The upper end of position plate 51 is connected with a lobe plate 52.Meanwhile, the bottom of the ratchet 22 is provided with a detent pin 221, the lobe plate 52
The other end connect the detent pin 221.That is, after the electromagnet 30 moves right, touch the restoring board 51 and move right, by this
Lobe plate 52 promotes the detent pin 221 to be moved to the left, and drives the ratchet 22 to be moved to the left, and releases the fixing to the ratchet 21.
In summary, remote-operable control machine-room-less speed limiter uses the side that mechanical ratchet and pawl coordinates
Formula, makes mechanical action more stable, and solves the problems, such as to be easy to produce the sound that claw hits with ratchet in original technology.Meanwhile, one
Individual electromagnet can meet two action requests for fixing and releasing and fix, so that more convenient and simple in manipulation.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
