By connecting spring 3 between speed limit device wheel 4 and wind pressure type collision block 2, so that when overhauling elevator uplink leveling, limiter of speed
Wheel 4 reversely rotates, and in the effect for not needing external force, spring 3 grants the elastic force that wind pressure type collision block 2 one is directed toward speed limit device wheel 4, so that
The distance between wind pressure type collision block 2 and speed limit device wheel 4 automatically reply at a distance from normal working condition.By the way that spring 3 is arranged, i.e.,
It can make to automatically reply normal working condition between wind pressure type collision block 2 and speed limit device wheel 4, and make the structure of the utility model more
Add that simple, manufacture is more convenient, cost is cheaper.
The course of work of the utility model includes: that central axis 5 is fixed in limiter of speed mounting base, and speed limit device wheel 4 is turned left,
Wind pressure type collision block 2 is driven to rotate when speed limit device wheel 4 rotates, because of gas pressure, wind pressure type collision block 2 is on central axis 5, its lug
21 move along the opening direction of groove 42, to braked wheel 1；When reaching certain speed, wind pressure type collision block 2 connects with braked wheel 1
Touching, braked wheel 1 are braked speed limit device wheel 4, and limiter of speed enters on-position.
When electric loop recovery, overhauling elevator uplink leveling, speed limit device wheel 4 is turned right, and wind pressure type collision block 2 is detached from braked wheel
1, and sprung back under the effect of 3 tensile force of spring, 4 resumption of service of speed limit device wheel, i.e. limiter of speed enters recoil state.
When needing to adjust speed limit speed, the threaded ends of rotation brake wheel 1 and central axis 5, so that central axis 5 is screwed into
Or back-out, and then adjust braked wheel 1 with speed limit device wheel 4 at a distance from, and then reach adjustment wind pressure type collision block 2 arrival braked wheel 1 when
Speed, be finally reached adjustment speed limit speed purpose.
The utility model is not limited to above embodiment, if various changes or modifications to the utility model do not take off
Spirit and scope from the utility model, if these modification and variations belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to encompass these changes and changes.
