Background technology
The CD-ROM drive motor of existing high storied building elevator is direct axle transmission drive wheel, again with drive wheel elevator lifting rope to reach the purpose of elevator lifting.Lift car all can link with cable wire according to its weight in the stack-mounted process have clump weight, so that the weight of pouring weight and car is near balance, and is beneficial to the running of elevator.But equilibrium point is not easy control; Weight after the personnel of adding get into, it is heavier roughly all to have one side, also because the relation of counterweight; After brake is removed in the elevator cage; Can be toward weight than double recipe to slippage, be prone in the slipping cause elevator to rise or the excessive velocities of falling produces danger, sometimes even cause personal casualty in the compartment because of inertia slippage, acceleration due to gravity relation.For addressing the above problem, existing elevator all is equipped with velocity limiter usually, but existing velocity limiter complex structure, unstable properties and noise are bigger.
The utility model content
The utility model is to the defective that above-mentioned background technology exists a kind of simple in structure, stable performance and the little velocity limiter of noise to be provided.
For realizing above-mentioned purpose, the utility model discloses a kind of velocity limiter, it comprises the velocity limiter pedestal; Said velocity limiter pedestal is hinged with rope sheave; Said rope sheave is wound with overspeed governor, and a side of said rope sheave is equipped with ratchet and pawl, is hinged with the rope stop mechanism on the said ratchet; One end of said overspeed governor is connected with first connecting arm, and said first connecting arm is hinged with second connecting arm, is provided with elastic component between said first connecting arm and the car, and said second connecting arm links to each other with the shadoof of safety tongs.
Further; Said rope stop mechanism is provided with and said ratchet pivotally attached pull bar; Said pull bar is connected with an end of brake shoe brake cheek pedestal; The other end of said brake shoe brake cheek pedestal is hinged on the velocity limiter pedestal through first adapter shaft, and said brake shoe brake cheek pedestal is hinged with and the cooresponding brake shoe brake cheek of said overspeed governor through second adapter shaft.
Further, said drag link sleeve is provided with first spring, and an end of this first spring is replaced the end at pull bar, and the other end is replaced on said brake shoe brake cheek pedestal.
Further, said elastic component is second spring, and said second spring housing is located on the guide pillar.
Further, said velocity limiter also comprises the auxiliary fixing seat that is fixed on the car, and this auxiliary fixing seat is hinged with the 3rd connecting arm, and the other end of said the 3rd connecting arm links to each other with said first connecting arm.
In sum; The utility model velocity limiter is through the cooperation of said each parts, and when excessive velocities that elevator rises or descends, said ratchet links to each other with said ratchet engaged because of receiving action of centrifugal force; Said ratchet drives the said overspeed governor of said rope stop mechanism clamping; And under the effect of the elastic force of said elastic component and safety tongs, car is steadily stopped, having simple in structure, stable performance and the little advantage of noise.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.
See also Fig. 1; The utility model velocity limiter comprises velocity limiter pedestal 1 and is fixed on the auxiliary fixing seat 2 on the car; Said velocity limiter pedestal 1 is hinged with rope sheave 3; Said rope sheave 3 is wound with overspeed governor 4, and a side of said rope sheave 3 is equipped with ratchet 5 and ratchet 6, is hinged with the rope stop mechanism on the said ratchet 5.
Said rope stop mechanism is provided with and said ratchet 5 pivotally attached pull bars 7; Said pull bar 7 is connected with an end of brake shoe brake cheek pedestal 8; The other end of said brake shoe brake cheek pedestal 8 is hinged on the velocity limiter pedestal 1 through first adapter shaft 9, and said brake shoe brake cheek pedestal 8 is hinged with and said overspeed governor 4 cooresponding brake shoe brake cheek 11 through second adapter shaft 10.Said pull bar 7 is arranged with first spring 12, and an end of this first spring 12 is replaced the end at pull bar 7, and the other end is replaced on said brake shoe brake cheek pedestal 8.
One end of said overspeed governor 4 is connected with first connecting arm 13; Said first connecting arm 13 is hinged with second connecting arm 14; Be provided with elastic component 15 between said first connecting arm 13 and the car; In the present embodiment, said elastic component 15 is second spring, and said second spring housing is located on the guide pillar 16.One end of said guide pillar 16 and said auxiliary fixing seat 2 are hinged, and the other end links to each other with the 3rd adapter shaft 17 on being plugged in said first connecting arm 13 and second connecting arm 14.Said second connecting arm 14 links to each other with the shadoof 19 of safety tongs.Said auxiliary fixing seat 2 is hinged with the 3rd connecting arm 18, and the other end of said the 3rd connecting arm 18 links to each other with said the 3rd adapter shaft 17, thereby forms the form that said first connecting arm 13 links to each other with said second connecting arm 14 and the 3rd connecting arm 18.
The principle of work of the utility model is: when excessive velocities that elevator rises or descends; Said ratchet 6 links to each other with said ratchet 5 engagements because of receiving action of centrifugal force; Said ratchet 5 drives the said overspeed governor 4 of said rope stop mechanism clamping; And under the effect of the elastic force of said elastic component 15 and safety tongs, car is steadily stopped.Through said the 3rd connecting arm 18 is set, thereby when overspeed governor 4 is upwards mentioned said first connecting arm 13, avoid because of the elastic force of elastic component 15 with said first connecting arm 13 and second connecting arm 14 jack-up to the left.
