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 is in operation, no matter which kind of reason makes car exceed the speed limit, the danger of even falling, and in the out-of-action situation of every other safety guard, then velocity limiter and safety tongs generation linkage action, makes lift car stop.
Current existing elevator governor, the structure mostly as Chinese patent application 200580039944.9 disclosed in, normally when rope sheave rotating speed is too fast, pulls brake shoe brake cheek to go braking by pull bar.This brake mode is the friction braking of carrying out local to rope sheave periphery, therefore there is the defect that braking force is little, is difficult to be applicable to some high-performance elevators.When needs are for high-power elevator, generally can go to reach enough braking forces by the number increasing brake shoe brake cheek, therefore can increase the complexity of structure, raised productive costs, and integral structure be more open, volume is comparatively large, is not easy to concrete installation.
Summary of the invention
The object of the invention is to, a kind of disengaging type elevator governor is provided.It can improve lock torque, and self structure is compact, is beneficial to installation.
Technical scheme of the present invention: disengaging type elevator governor, is characterized in: comprise rope sheave, the rotating shaft two ends of rope sheave are separately fixed on left support plate and right support plate, described rotating shaft are also provided with the independent platen rotated; Platen is provided with friction lining near the side of rope sheave, is provided with a circle well-distributed helical teeth, right support plate is also provided with the helical teeth be meshed with the helical teeth of platen near the side of right support plate; Platen is also fixed with ratchet near the side of rope sheave, and ratchet stretches into inside rope sheave, is also provided with hanging hook assembly inside rope sheave, and hanging hook assembly is connected with rope sheave by rotational pin, and hanging hook assembly is positioned at outside ratchet.
In above-mentioned disengaging type elevator governor, when rope sheave rotating speed is too fast, the centnifugal force that hanging hook assembly is subject to exceedes the backward interior action of activation threshold value, and hanging hook assembly is linked in the ratchet of ratchet, and then orders about the platen fixing with ratchet and rotate; When platen rotates, the helical teeth of the helical teeth on platen and right support plate misplaces, and the spacing of platen and right support plate increases, and forces platen to press to rope sheave; Friction braking is realized under the compressing of the then friction lining of rope sheave on platen.
In aforesaid disengaging type elevator governor, in order to braking force can be made to be cushioned, and platen can reset, and described platen is fixed with multiple pull bar through right support plate, is provided with the first spring outside pull bar; First spring one end and tie rod end are fixed, and the other end props up right support plate; Protecting sleeve is provided with outside first spring and pull bar.
In aforesaid disengaging type elevator governor, described hanging hook assembly comprises hook end and centrifugal end, and the junction of hook end and centrifugal end is located on rotational pin, and centrifugal end is connected with rope sheave by the second spring, and centrifugal end is fixed with clump weight.
In aforesaid disengaging type elevator governor, left support plate and right support plate lower end are linked together by connecting panel.
Compared with prior art, the present invention provides braking force by making the mode of the helical teeth of platen and right support plate generation dislocation, platen carries out disengaging type compression braking from the side of rope sheave can be realized, the braking force of this brake mode more balances, and the braking force that can provide is also larger, can be applicable to some high-performance lift facilities preferably.And the present invention takes full advantage of the inner space of rope sheave, the structure of whole velocity limiter is very compact, facilitates ready-made installation widely.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.Disengaging type elevator governor, as depicted in figs. 1 and 2: comprise rope sheave 2, rotating shaft 13 two ends of rope sheave 2 are separately fixed on left support plate 1 and right support plate 7, described rotating shaft 13 are also provided with the independent platen 6 rotated; Platen 6 is provided with friction lining 5 near the side of rope sheave 2, is provided with a circle well-distributed helical teeth, right support plate 7 is also provided with the helical teeth be meshed with the helical teeth of platen 6 near the side of right support plate 7; Platen 6 is also fixed with ratchet 11 near the side of rope sheave 2, and ratchet 11 stretches into inside rope sheave 2, is also provided with hanging hook assembly 4 inside rope sheave 2, and hanging hook assembly 4 is connected with rope sheave 2 by rotational pin 3, and hanging hook assembly 4 is positioned at outside ratchet 11.Described platen 6 is fixed with multiple pull bar 10 through right support plate 7, outside pull bar 10, is provided with the first spring 9; First spring 9 one end and pull bar 10 end winding support, the other end props up right support plate 7; Protecting sleeve 8 is provided with outside first spring 9 and pull bar 10.Described hanging hook assembly 4 comprises hook end 401 and centrifugal end 402, and the junction of hook end 401 and centrifugal end 402 is located on rotational pin 3, and centrifugal end 402 is connected with rope sheave 2 by the second spring 404, and centrifugal end 402 is fixed with clump weight 403.Left support plate 1 and right support plate 7 lower end are linked together by connecting panel 12.
Principle of work of the present invention: when rope sheave 2 rotating speed is too fast, the pulling force that the centrifugal end 402 of hanging hook assembly 4 overcomes the second spring 404 under the centrifugal effect of clump weight 403 laterally rotates, now hook end 401 turns to the inside, and be linked in the ratchet of ratchet 11, and then order about the platen 6 fixing with ratchet 11 and rotate; When platen 6 rotates, the helical teeth of the helical teeth on platen 6 and right support plate 7 misplaces, and platen 6 increases with the spacing of right support plate 7, forces platen 6 to press to rope sheave 2; Friction braking is realized under the compressing of the then friction lining 5 of rope sheave 2 on platen 6.
