Description
Technical field
The present invention relates to a kind of elevator governor, particularly a kind of disengaging type elevator governor.
Background technology
Elevator governor, is one of safety con-trol part in elevator safety protection system.When elevator in operation no matter
Which kind of reason makes car exceed the speed limit, or even the danger fallen, and the inoperative feelings of every other safety guard
Under condition, then linkage action occurs for limiter of speed and safety tongs, stops lift car.
Current existing elevator governor, the structure as disclosed in Chinese patent application 200580039944.9, leads to mostly
It is often, when rope sheave rotating speed is too fast, to pull brake-shoe to go braking by pull bar.This mode of braking is carried out to rope sheave periphery
Local friction catch, therefore there is the small defect of brake force, it is difficult to be applied to some powerful elevators.When needs are used for greatly
During power elevator, typically it can go to reach enough brake force by increasing the number of brake-shoe, therefore the complexity of structure can be increased
Degree, has raised production cost, and overall structure is more open, and volume is larger, is not easy to specific installation.
The content of the invention
It is an object of the present invention to provide a kind of disengaging type elevator governor.It can improve braking moment, and itself
Compact conformation, beneficial to installation.
Technical scheme：Disengaging type elevator governor, is characterized in：Including rope sheave, the rotating shaft two ends point of rope sheave
It is not fixed in left support plate and right support plate, the platen of independent rotation is additionally provided with the rotating shaft；Platen close to rope sheave one
Side is provided with friction plate, encloses and also is provided with and platen in equally distributed helical teeth, right support plate provided with one close to the side of right support plate
The helical teeth that is meshed of helical teeth；Platen is further fixed on ratchet close to the side of rope sheave, and ratchet is stretched on the inside of rope sheave, on the inside of rope sheave also
Provided with hanging hook assembly, hanging hook assembly is connected by rotational pin with rope sheave, and hanging hook assembly is located on the outside of ratchet.
In above-mentioned disengaging type elevator governor, when rope sheave rotating speed is too fast, the centrifugal force that hanging hook assembly is subject to, which exceedes, to be touched
The backward interior action of threshold value is sent out, hanging hook assembly is linked into the ratchet of ratchet, and then drives the platen fixed with ratchet to rotate；Pressure
During disc spins, the helical teeth of helical teeth and right support plate on platen misplaces, the spacing increase of platen and right support plate, forces pressure
Disk presses to rope sheave；Then friction catch is realized under the compressing of friction plate of the rope sheave on platen.
In foregoing disengaging type elevator governor, in order to be buffered brake force, and platen can reset, institute
State and multiple pull bars through right support plate are fixed with platen, pull bar is externally provided with the first spring；First spring one end and drag link end
Portion is fixed, and the other end props up right support plate；First spring and pull bar are externally provided with protective case.
In foregoing disengaging type elevator governor, the hanging hook assembly includes hook end and centrifugation end, hook end and centrifugation
The junction at end is located on rotational pin, and centrifugation end is connected by second spring with rope sheave, and centrifugation end is fixed with balancing weight.
In foregoing disengaging type elevator governor, left support plate and right support plate lower end are linked together by connecting plate.
Compared with prior art, by the present invention in that platen and the helical teeth of the right support plate mode that misplaces provides system
Power, it is possible to achieve platen carries out the compression braking of disengaging type from the side of rope sheave, the brake force of this mode of braking is more flat
Weighing apparatus, and the brake force that can be provided is also bigger, can preferably be applied to some powerful lift facilities.And the present invention fills
Point make use of the inner space of rope sheave, whole limiter of speed it is extremely compact, greatly facilitated ready-made installation.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.Disengaging type elevator governor, as depicted in figs. 1 and 2：Including rope sheave 2, the two ends of rotating shaft 13 point of rope sheave 2
It is not fixed in left support plate 1 and right support plate 7, the platen 6 of independent rotation is additionally provided with the rotating shaft 13；Platen 6 is close to rope
The side of wheel 2 is provided with friction plate 5, is enclosed close to the side of right support plate 7 provided with one in equally distributed helical teeth, right support plate 7
The helical teeth being meshed provided with the helical teeth with platen 6；Platen 6 is further fixed on ratchet 11 close to the side of rope sheave 2, and ratchet 11 stretches into rope
The inner side of wheel 2, the inner side of rope sheave 2 is additionally provided with hanging hook assembly 4, and hanging hook assembly 4 is connected by rotational pin 3 with rope sheave 2, hanging hook assembly 4
In the outside of ratchet 11.Multiple pull bars 10 through right support plate 7 are fixed with the platen 6, pull bar 10 is externally provided with the first spring
9；The one end of first spring 9 is fixed with the end of pull bar 10, and the other end props up right support plate 7；First spring 9 and pull bar 10 are externally provided with guarantor
Sheath 8.The hanging hook assembly 4 includes hook end 401 and centrifugation end 402, and hook end 401 and the junction at centrifugation end 402 are located at
