The specific embodiment
Fig. 1 is provided with the front elevation of cage 1 of the emergency braking apparatus 10 of present embodiment for expression.Among the figure, emergency braking apparatus 10 is installed in the bottom by the cage 1 of 2 guiding of the guide rail in the elevating road, has the function that pushing guide rail 2 stops cage 1 when cage 1 speedup is very big.
Describe the emergency braking apparatus 10 of present embodiment below in detail.
Fig. 2 is the front elevation of the emergency braking apparatus 10 of expression present embodiment, and Fig. 3 is the section-drawing that cuts off the emergency braking apparatus 10 of present embodiment along the A-A line.As shown in these figures, the 11st, be installed on the framework of cage 1 bottom.The 12nd, be installed on the central portion of framework 11 and in accommodating wall 12a, accommodate the clamping component of the concavity of guide rail 2.The 13rd, be fixed in the lever of framework 11 sidepieces pivotally.14 be mounted on the lever 13, can make the front end of lever 13 be the governor rope that swings up and down.The 15th, be fixed on pivotally on the clamping component 12 and be contained in the oval-shaped roller on the wall 12a of accommodating of clamping component 12 by axis of revolution 15a with guide rail 2.The 16th, the slotted hole that is formed at the leading section of lever 13, extends along the length direction of lever 13.The 17th, convex is arranged at the circumference on roller 15 minor axis and inserts the pin of slotted hole 16 slidably.
Wherein, roller 15 ovalizes, the interval of axis of revolution 15a and guide rail 2 is greater than minor axis but less than major diameter.Like this, behind the configuration roller 15, it is at interval fixed to some extent to form between roller 15 and the guide rail 2, and the major diameter direction of the bearing of trend of guide rail 2 and roller 15 forms parastate.Again, when the minor axis direction of the bearing of trend of guide rail 2 and roller 15 be parastate near the time, roller 15 and guide rail 2 butts.
It is big but than the width of guide rail 2 and the little state of major diameter sum of roller 15 that the groove width of accommodating wall 12a is adjusted to minor axis sum than the width of guide rail and roller 15.
The following describes the action of the emergency braking apparatus 10 of present embodiment.At first, cage 1 move in institute's constant speed degree during, move with identical speed because of governor rope 14 is also the same with cage 1, so governor rope 14 can not stretch lever 13.As shown in Figure 2, lever 13 can be kept horizontality all the time, and the slotted hole 16 that forms on the lever 13 also is in level, and the pin 17 that inserts slotted hole 16 is positioned at the left end of slotted hole 16.At this moment, be formed at because of pin 17 on the minor axis of roller 15, so the minor axis of roller 15 is in level.The result forms fixed to some extent interval between roller 15 and the guide rail 2, roller 15 can not push guide rail 2.
Secondly, cage 1 is speedup downwards, and the constant speed degree carries out when mobile when surmounting, and governor (not shown) detects the speedup of cage 1, governor rope 14 clampings that will expose downwards with the speed identical with cage 1.Lever 13 pull-ups that to be fixed in governor rope 14 by clamping governor rope 14 as shown in Figure 4, are pushed to the pin 17 in the slotted hole 16 of insertion lever 13 front ends upward.Because of pin 17 is fixed on the roller 15, so roller 15 is the clockwise direction revolution of center along figure with axis of revolution 15a.Roller 15 is not the long shape of circle but above-below direction.Thus, roller 15 is sandwiched between clamping component 12 and the guide rail 2, by roller 15 being snapped in clamping component 12 and the guide rail 2 (pushing), cage 1 is promptly stopped.
Again, cage 1 is speedup upward, and the constant speed degree carries out when mobile when surmounting, and governor (not shown) detects the speedup of cage 1, governor rope 14 clampings that will expose upward with the speed identical with cage 1.By clamping governor rope 14, the lever 13 that will be fixed in governor rope 14 is left behind, and as shown in Figure 5, the pin 17 in the slotted hole 16 of insertion lever 13 front ends is pushed down downwards.Because of pin 17 is fixed on the roller 15, so roller 15 is the anticlockwise direction revolution of center along figure with axis of revolution 15a.Thus, roller 15 is sandwiched between clamping component 12 and the guide rail 2, by roller 15 being snapped in clamping component 12 and the guide rail 2 (pushing), cage 1 is promptly stopped.
As mentioned above, in the emergency braking apparatus 10 of present embodiment, owing to adopted up-and-down movement by lever 13 to make oval-shaped roller 15 revolutions, roller 15 is snapped in very simply structure in the guide rail 2 (pushing), therefore, no matter any speedup of above-below direction has taken place, and cage 1 is promptly stopped.Like this, compare, can increase substantially durability and reliability with traditional emergency braking device.
The following describes the 1st variation of the emergency braking apparatus 10 of present embodiment.The right side wall 40 of accepting groove 12a that Fig. 6 is arranged at clamping component 12 for expression be upper and lower to the partial enlarged drawing of inclination example.As shown in the figure, the latter half of right side wall 40 is the state that the groove width of accommodating wall 12a expands out gradually that is inclined to.Like this, compare with the occasion that speedup downwards corresponding to cage 1 makes roller 15 snap in right side wall 40 the first half along the clockwise direction revolution of figure, with roller 15, then to make roller 15 snap in occasion one side's the amount of snapping in of right side wall 40 the latter halfs along the anticlockwise direction revolution of figure, with roller 15 little with speedup upward corresponding to cage 1.The result compares with the static force of the occasion of speedup downwards of cage 1, and is then little with static force one side of the occasion of speedup upward of cage 1.
It is as follows to utilize upper and lower always to change the principle of static force.At first, when cage 1 downwards during speedup, because of gravity also applies downwards, so need big static force for cage 1 is stopped.Otherwise, when cage 1 upward during speedup,, to compare with above-mentioned occasion because of gravity applies in the opposite direction, available little static force stops cage 1.Like this, when above-below direction is identical static force, with speedup downwards and the occasion that stops rapidly being compared cage 1 speedup and bigger reaction force can take place for the occasion one that stops rapidly upward then.When this reaction force becomes problem, shown in this variation,, therefore can reduce by the big reaction force that promptly stops to be taken place because the right side wall 40 of clamping component 12 is tilted.
The 1st variation is the structure that the groove width that the latter half of the right side wall 40 of clamping component 12 is inclined to accommodate wall 12a expands out gradually, but the structure that the groove width that also can adopt the first half of the right side wall 40 that makes clamping component 12 to be inclined to accommodate wall 12a expands out gradually.This occasion also can obtain the effect identical with the 1st variation.
The following describes the 2nd variation of the emergency braking apparatus 10 of present embodiment.Fig. 7 is the partial enlarged drawing of the locality variation of expression roller 41 shapes.As shown in the figure, facial 41a is cancelled because of the upper right side of roller 41, with speedup downwards corresponding to cage 1 roller 41 is compared along the clockwise direction revolution of figure, the occasion that the facial 41b in lower right side of roller 41 is snapped into right side wall 40, then to make roller 41 snap in occasion one side's the amount of snapping in of right side wall 40 along the anticlockwise direction revolution of figure, with the facial 41a in the upper right side of roller 41 little with speedup upward corresponding to cage 1.The result compares with the static force of the occasion of speedup downwards of cage 1, and is then little with static force one side of the occasion of speedup upward of cage 1.The result can reduce effectively when cage 1 speedup and the big reaction force that takes place when stopping rapidly upward.
The following describes the 3rd variation of the emergency braking apparatus 10 of present embodiment.Fig. 8 is installed on above-below direction bevelled hang plate 42 partial enlarged drawing of right side wall 40 examples of clamping component 12 convertibly for expression.As shown in the figure, because of the latter half of hang plate 42 is inclined to the state that groove width expands out gradually, so and speedup downwards corresponding to cage 1 makes roller 15 compare along the clockwise direction revolution of figure, the occasion that roller 15 is snapped into the first half of hang plate 42, then to make roller 15 snap in occasion one side's the amount of snapping in of the latter half of hang plate 42 along the anticlockwise direction revolution of figure, with roller 41 little with speedup upward corresponding to cage 1.The result compares with the static force of the occasion of speedup downwards of cage 1, and is then little with static force one side of the occasion of speedup upward of cage 1.The result can reduce effectively when cage 1 speedup and the big reaction force that takes place when stopping rapidly upward.Again, commutative because of hang plate 42, so have the hang plate 42 of differing tilt angles, can change static force according to situation by installation.
The 3rd variation is to make the latter half of hang plate 42 be inclined to the state that groove width expands out gradually, but also can adopt the first half that makes hang plate 42 to be inclined to the state that groove width expands out gradually.This occasion also can obtain the effect identical with the 3rd variation.
Utilizability on the industry
The present invention is owing to also can make easily cage stop and electricity simple in structure when speedup can be provided upward Therefore the emergency braking apparatus of ladder, has applicable to home-use elevator and the requirement in for example low price zone The elevator of durability.
