Abstract
The utility model discloses a machine room-free speed limiter which comprises a machine frame, a rope wheel, an electromagnet switch, a striking plate, a main shaft, a pawl and a ratchet wheel, wherein the ratchet wheel is fixed on the main shaft, and the rotation range of the ratchet wheel is determined by a lock pin; the electromagnet switch is fixed on the outer wall of the machine frame and is provided with an extension rod; the striking plate is fixed on the machine frame through a shaft pin; the extension rod is connected with one end of the striking plate, and the other end of the striking plate is connected with a returning spring; the other end of the returning spring is fixed on the machine frame; the pawl is fixed on the rope wheel and is matched with the ratchet wheel; the speed limiter is characterized in that the machine frame is also provided with a linkage striking plate; the linkage striking plate is fixed on the machine frame through the shaft pin and is positioned on other side of the ratchet wheel and is symmetrical with the striking plate; and a connection rod is arranged between the striking plate and the linkage striking plate, and the striking plate and the linkage striking plate are connected through the connection rod to form a double-linkage structure. The designed double-linkage mechanism ensures that the maximum sliding distance under the action of an elevator is shorted by half, the action time of the electromagnet switch can be reduced by half simultaneously, and the service life of the speed limiter is prolonged.
Description
Technical field
The utility model relates to a kind of lift appliance, particularly machine-room-less speed limiter.
Background technology
Be installed in the machine-room-less speed limiter in the elevator hoistways; Main effect is a speed limit; When overruning, can play good safety control; Close beta actuating mechanism about machine-room-less speed limiter mainly is that rope sheave rotates weekly actuating mechanism, and weekly actuating mechanism can make the elevator coasting distance long when reality is used, and causes slide car phenomenon.Make the step switch crawl overlong time of velocity limiter simultaneously, influence the service life of switch.
The utility model content
The purpose of the utility model is for the deficiency that solves above-mentioned prior art a kind of safe and reliable machine-room-less speed limiter to be provided.
To achieve these goals, the utility model institute design-calculated machine-room-less speed limiter comprises frame, rope sheave, electro-magnet switch, re-packs, main shaft, pawl-and-gearing that ratchet is fixed on the main shaft; And confirm slewing area through lock pin, electro-magnet switch is fixed on the frame outer wall, and electro-magnet switch is provided with extension bar; Re-packing is fixed on the frame through pivot pin, and extension bar connects with the end that re-packs, and the other end that re-packs is connected to retracing spring; The retracing spring other end is fixed on the frame, and ratchet is fixed on the rope sheave, and matches with ratchet; It is characterized in that also being provided with on the frame interlock and re-pack, interlock re-packs and is fixed on the frame through pivot pin, and interlock re-packs and is positioned at the ratchet another side; With the symmetrical setting that re-packs, re-pack and interlock is provided with connecting rod between re-packing, connect through connecting rod to constitute the moving structure of duplex.
Be fixed with torsion spring between described ratchet and rope sheave, described ratchet is a wheel word.
The machine-room-less speed limiter that the utility model obtains, this machine-room-less speed limiter are the duplex actuation mechanism, when work; Re-packing earlier, the promotion ratchet cooperates with ratchet; Perhaps interlock re-packs and promotes ratchet is cooperated with ratchet again, makes the velocity limiter action simultaneously, to play the effect of speed limit; The circle of will walking around with respect to former makes the velocity limiter action by the effect of re-packing again; It is half that existing design-calculated duplex actuation mechanism has shortened the maximum coasting distance under the elevator running-active status, the time decreased of electro-magnet switch action simultaneously half the, the service life of so also having improved switch.
Description of drawings
Fig. 1 is an embodiment integral structure scheme drawing;
Fig. 2 is the structural representation of interlock when re-packing work;
Fig. 3 is the left view of Fig. 1.
Among the figure: frame 1, rope sheave 2, ratchet 3, electro-magnet switch 4, re-pack 5, ratchet 6, retracing spring 7, extension bar 8, connecting rod 9, interlock re-pack 10, main shaft 11, lock pin 12.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment:
Like Fig. 1, shown in Figure 3, the machine-room-less speed limiter that present embodiment provides comprises frame 1, rope sheave 2, electro-magnet switch 4, re-packs 5, main shaft 11, ratchet 6 and ratchet 3; Ratchet 3 is installed on the main shaft 11 with rope sheave 2, is fixed on then on the frame 1, and confirms slewing area through lock pin 12; Electro-magnet switch 4 is fixed on frame 1 outer wall, and electro-magnet switch 4 is provided with extension bar 8, re-packs 5 to be fixed on frame 1 through pivot pin; Extension bar 8 connects with 5 one lower ends that re-pack, and 5 the other end of re-packing is equipped with retracing spring 7, and retracing spring 7 other ends are fixed on the frame 1; After guaranteeing that work is accomplished, can let re-packs 5 resets at the home position, and ratchet 6 is contained on the rope sheave 2; And match with ratchet 3,2 of ratchet 6 and rope sheaves are equipped with torsion spring, and described ratchet 6 is a wheel word; Also being provided with interlock on the frame 1 and re-packing 10, interlock re-packs and 10 is fixed on the frame 1 through pivot pin, and interlock re-packs and 10 is positioned at ratchet 3 another sides; With the 5 symmetrical settings that re-pack, re-pack 5 and interlock re-pack and be provided with connecting rod 9 between 10, connect through connecting rod 9 and constitute the moving structure of duplexs.
The manner of execution of the design's machine-room-less speed limiter is mainly: after electro-magnet switch 4 energisings, electro-magnet switch 4 stretches out head immediately, and is shown in Figure 1; Promoted to re-pack 5 by extension bar 8, the 5 drive ratchets 6 that re-pack are buckled on the ratchet 3 ratchet 6, drive interlock through the 9 same times of connecting rod that connect between the two simultaneously and re-pack 10; Shown in Figure 2; Make that cross 5 the ratchet 6 of re-packing rotates to interlock when re-packing 10 positions, let ratchet 6 be buckled on the ratchet 3, finally reach the speed limit action.
