The specific embodiment
The 1st embodiment
With reference to the accompanying drawings embodiments of the present invention are described.Fig. 1 to Fig. 3 is the figure of the 1st embodiment of expression speed limiter for elevator of the present invention.
As shown in Figure 2, in the side of elevator cage 14 overspeed governor 12 is set, this overspeed governor 12 is connected with safe connecting rod (safety linkage) 13 on being arranged on elevator cage 14.
And make overspeed governor 12 bear clamping action by speed limiter for elevator 1.
Speed limiter for elevator 1 possesses as shown in Figure 1: the rope sheave 2 that is wound with overspeed governor 12; Surround the velocity limiter pedestal 9 of rope sheave 2; With rope sheave 2 with axle mounting and the ratchet 3 that freely rotates with rope sheave 2.
Ratchet 4 is installed on the rope sheave 2, bar 5 is installed on the ratchet 3.Spring 6 and brake shoe brake cheek pedestal 7 are installed on bar 5, and brake shoe brake cheek pedestal 7 is installed on the velocity limiter pedestal 9 by the 1st 8.And on brake shoe brake cheek pedestal 7, brake shoe brake cheek 10 is installed by the 2nd 11.At this moment, with the 1st 8 sides in the brake shoe brake cheek pedestal 7 as an end 7b, bar 5 sides as another end 7c.And the brake shoe brake cheek pedestal 7 that is installed on the bar 5 is pushed to rope sheave 2 sides by spring 6.
And as shown in Figure 1, brake shoe brake cheek pedestal 7 is arranged on the oblique upper of rope sheave 2, and therefore with prior art comparison shown in Figure 11, the horizontal direction of velocity limiter pedestal 9 (left and right directions of Fig. 1) length shortens, and speed limiter for elevator 1 forms as a whole compactly.
As shown in figures 1 and 3, brake shoe brake cheek pedestal 7 is installed on the velocity limiter pedestal 9 by the 1st 8, and when velocity limiter described later moved, brake shoe brake cheek pedestal 7 rotated to the arrow A direction, thereby brake shoe brake cheek 10 is pushed to overspeed governor 12.
And brake shoe brake cheek 10 is under the initial condition that velocity limiter is failure to actuate, and the direction that the rotation direction (arrow A direction) of the brake shoe brake cheek pedestal 7 of brake shoe brake cheek 10 when moving with velocity limiter is identical is rotated, and engages with brake shoe brake cheek pedestal 7.
That is, form the excision 10a of portion on the backward rotation direction part 10c with respect to the 2nd 11 in brake shoe brake cheek 10, make the rotation direction part 10b ratio inverse rotation direction part 10c of brake shoe brake cheek 10 heavy.Therefore brake shoe brake cheek 10 be middle mind-set arrow A direction rotation with the 2nd 11, but under initial condition, because of with brake shoe brake cheek pedestal 7 butts, the rotation of brake shoe brake cheek 10 stops.
Effect to the present embodiment that is made of this structure describes below.
Under the initial condition before the velocity limiter action, brake shoe brake cheek 10 passes through brake shoe brake cheek pedestal 7, does not rotate and remains on initial condition.And, when velocity limiter moves, ratchet 4 engaging-in ratchets 3, ratchet 3 rotates with rope sheave 2.Because the rotation of ratchet 3, bar 5 tensions, spring 6 are compressed.Spring 6 is pushed brake shoe brake cheek pedestal 7, and the brake shoe brake cheek 10 that is installed on the brake shoe brake cheek pedestal 7 is pushed overspeed governor 12.Overspeed governor 12 makes the safety of elevator cage connect 13 actions by this pressing force, thereby elevator cage 14 is stopped safely.
According to aforesaid present embodiment, by the 10a of excision portion is set on brake shoe brake cheek 10,, rotate to the arrow A direction if can make the not excision 10a of portion then the brake shoe brake cheek 10 that will rotate to the arrow B direction.
Thus, the identical direction of rotation direction of brake shoe brake cheek 10 brake shoe brake cheek pedestal 7 when moving with velocity limiter under initial condition is rotated, and it is stopped because of engaging with brake shoe brake cheek pedestal 7.
Therefore, brake shoe brake cheek pedestal 7 can be arranged on the top of rope sheave 2, and can make speed limiter for elevator single-piece compact shape.And, also the position of brake component that will brake shoe brake cheek pedestal 7 be arranged on opposite in the past direction on, brake shoe brake cheek 10 is not interfered with brake component when velocity limiter moves.Therefore, when velocity limiter moves, can carry out clamping action reliably, and can make velocity limiter single-piece compact shape overspeed governor 12.
The 2nd embodiment
Below, according to Fig. 4 and Fig. 5 the 2nd embodiment of the present invention is described.
The 2nd embodiment that Fig. 4 and Fig. 5 represent is, the 10a of excision portion is not set on brake shoe brake cheek 10, but make the 2nd 11 along the arrow C direction to backward rotation direction part 10a side shifting, so that the rotation direction part 10b ratio inverse rotation direction 10c with respect to the 2nd 11 is heavy.
In the 2nd embodiment that Fig. 4 and Fig. 5 represent, to giving identical symbol to the identical part of the 1st embodiment shown in Figure 3, and omit detailed description thereof with Fig. 1.
In Fig. 4 and Fig. 5, do not have at velocity limiter under the initial condition of action, brake shoe brake cheek 10 rotates to the arrow A direction, engages with brake shoe brake cheek pedestal 7 and stops.
According to present embodiment, the 10a of excision portion is not set on brake shoe brake cheek 10, and just changes the 2nd 11 position, brake shoe brake cheek 10 is rotated to the arrow A direction.
The 3rd embodiment
Below, according to Fig. 6 and Fig. 7 the 3rd embodiment of the present invention is described.
Fig. 6 and the 3rd embodiment shown in Figure 7 are, the 10a of excision portion is not set on brake shoe brake cheek 10, but mutual opposed pair of magnets 15,15 is installed on the both sides of brake shoe brake cheek pedestal 7 and brake shoe brake cheek 10, by the repulsive force of this magnet 15,15, brake shoe brake cheek 10 is rotated to the arrow A direction.
In Fig. 6 and the 3rd embodiment shown in Figure 7, to giving identical symbol to the identical part of the 1st embodiment shown in Figure 3, and omit detailed description thereof with Fig. 1.
In Fig. 6 and Fig. 7, under the initial condition that velocity limiter is failure to actuate, brake shoe brake cheek 10 rotates to the arrow A direction, engages with brake shoe brake cheek pedestal 7 and stops.
In addition, also can use the magnet 15,15 that attracts each other, brake shoe brake cheek 10 is rotated to the arrow A direction, perhaps at least one that also can be in brake shoe brake cheek pedestal 7 and brake shoe brake cheek 10 magnet is set, brake shoe brake cheek 10 is rotated to the arrow A direction.At this moment, another in brake shoe brake cheek pedestal 7 and the brake shoe brake cheek 10 is made of magnetic substance.
The 4th embodiment
Below, according to Fig. 8 to Figure 10 the 4th embodiment of the present invention is described.
Fig. 8 extremely the 4th embodiment shown in Figure 10 is, the 10a of excision portion is not set on brake shoe brake cheek 10, adjust counterweight 16 but install on the rotation direction part 10b in brake shoe brake cheek 10, make rotation direction part 10b ratio inverse rotation direction part 10c heavy by this adjustment counterweight 16 with respect to the 2nd.
To the 4th embodiment shown in Figure 10, to giving identical symbol to the identical part of the 1st embodiment shown in Figure 3, and omit detailed description thereof at Fig. 8 with Fig. 1.
In Fig. 8 to Figure 10, owing to install to adjust counterweight 16 on the rotation direction part 10b of brake shoe brake cheek 10, therefore under the initial condition that velocity limiter is failure to actuate, brake shoe brake cheek 10 rotates to the arrow A direction, engages with brake shoe brake cheek pedestal 7 and stops.
