Fig. 2 is the structural representation of the example representing elevator and the emergency braking apparatus thereof being provided with emergency braking apparatus of the present invention.Eliminate coupling member 11 and the diagram mentioning bar 12 in figs. 2 and 3.As shown in Figure 2, be provided with in the bottom of lift car 1 when there occurs exception the emergency braking apparatus that lift car 1 is braked, the brake equipment 4 of this emergency braking apparatus has can by the brake component described later be pressed on guide rail 2, in the left and right of lifting body, be disposed with at least two brake equipments 4 in the vertical direction.That is be provided with 4 brake equipments, they are bottom right layer brake equipment 4a, upper right layer brake equipment 4b, lower-left layer brake equipment 4c and upper left layer brake equipment 4d respectively.
In addition, as shown in Figure 3, brake equipment 4 has: the upper strata brake component 41 arranged in pairs in the mode that can clamp guide rail 2 and lower floor's brake component 42; The portion of mentioning 43,44 of brake component 41,42 and guide rail 2 moving contact is made when there occurs exception; Guide roller 45; When braking, the direction of direction guiding rail 2 applies the elastic body 46 of pressing force to brake component 41,42; And guiding elements 47,48.By these mention portion 43,44, guide roller 45, elastic body 46, guiding elements 47,48 and not shown mention the control mechanism that bar etc. forms brake equipment.
The brake component 41,42 of levels has the shape of wedge shape, and has the vertical brake surface relative with guide rail 2.When the brake component 41,42 of these levels is arranged in braking, under the guiding of guide roller 45, the dip plane along guiding elements 47,48 is raised portion 43,44 and mentions simultaneously, its brake surface and guide rail 2 moving contact and produce braking force.
Especially as shown in Figure 3, in the emergency braking apparatus of the present embodiment, the gap size L1 be between the upper strata brake component 41 of upper strata brake equipment 4b, 4d of readiness for action and guide rail 2 is set smaller than the gap size L2 between lower floor's brake component 42 of lower floor brake equipment 4a, 4c and guide rail 2.Its reason makes when emergency braking, and upper strata brake component 41 is more first than lower floor brake component 42 with guide rail 2 moving contact.
In the present embodiment, when usual, as shown in Figure 3, the brake component 41,42 of the levels of brake equipment 4 is in the readiness for action separated with guide rail 2., when the descending speed of lift car 1 there occurs hypervelocity because of certain fault, in order to be carried out emergency braking by 9 pairs of lift cars of the governor shown in Fig. 11, speed controller rope 9a is retrained by governor holding action.Further, along with the decline of lift car 1, the carrying up component 43,44 of control setup 4 is mentioned by the bar 12 of mentioning linked with the coupling member 11 shown in Fig. 1 simultaneously.
That is, before the speed declined in the hypervelocity of lift car exceeds 1.4 times of command speed, carry out the speed controller rope holding action of not shown governor, link therewith, mention bar 12 to carry out relative mentioning action relative to lift car, the carrying up component 43,44 of levels is mentioned upward at one time, and the brake component 41,42 of brake equipment 4 is also mentioned upward at one time.Thus, as shown in Figure 4, brake component 41,42 is pressed against on guide rail 2, is braked lift car 1 by friction force.
Now, owing to the gap size L1 between upper strata brake component 41 and guide rail 2 to be set smaller than the gap size L2 between lower floor's brake component 42 and guide rail 2, so upper strata brake component 41 first starts and guide rail 2 moving contact than lower floor brake component 42.Such as, by L1 is set as about 5mm, and L2 is set as about 3mm larger than L1, makes upper strata brake equipment first start to brake, after upper strata brake equipment starts to brake, more successfully make lower floor's brake equipment start to brake.
That is, poor by setting-up time, upper strata brake equipment 4b, 4d by by upper strata brake component 41 fully by being pressed on level and smooth guide rail 2, can braking force be obtained.On the other hand, lower floor brake equipment 4a, 4c owing to being positioned at the below of upper strata brake equipment 4b, 4d, so by by lower floor's brake component 42 by being pressed on level and smooth guide rail 2, certainly also can obtain braking force.In addition, although the time that the time that lower floor's brake component 42 of lower floor brake equipment 4a, 4c starts to carry out with guide rail 2 moving contact starts to carry out with guide rail 2 moving contact than the upper strata brake component 41 of upper strata brake equipment 4b, 4d is late, but because the time difference is between the two very little, so large impact can not be brought to stopping distance, by contrast, upper strata brake equipment 4b, 4d are by larger by being pressed in the effect that level and smooth guide rail 2 can obtain braking force by upper strata brake component 41.
According to the present embodiment, when carrying out emergency braking, by being pressed on level and smooth guide rail 2 by lower floor's brake component 42 of the upper strata brake component 41 of upper strata brake equipment 4b, 4d and lower floor brake equipment 4a, 4c, the deceleration and stopping performance that bottom right layer brake equipment 4a, upper right layer brake equipment 4b, lower-left layer brake equipment 4c and upper left layer brake equipment 4d are had separately can be played fully.Thereby, it is possible to effectively and stably brake, and the reliability of emergency braking apparatus can be improved.
Especially, by the gap size L1 between the upper strata brake component 41 of upper strata brake equipment 4b, 4d and guide rail 2 being set smaller than this method of gap size L2 between lower floor's brake component 42 of lower floor brake equipment 4a, 4c and guide rail 2, the deceleration and stopping performance that each brake equipment 4 has can be given full play to.To reduce costs and while implement device miniaturization thereby, it is possible to obtain, effectively and stably brake, and can improve the emergency braking apparatus of reliability.
In addition, in the present embodiment, as shown in Figure 3, the length M1 of upper strata brake component 41 is set as the length M2 length than lower floor brake component 42.When size being set as L1 < L2, in order to increase the braking force first starting upper strata brake equipment 4b, 4d of braking further, size can be set as M1 > M2.Certainly, when the braking force of upper strata brake equipment 4b, 4d fully can be ensured, then also M1=M2 can be set as.
The brake component 41,42 of levels preferably adopts identical material to form.On the other hand, in order to shorten braking time increase further start the braking force of the lower floor's brake equipment carrying out braking after than upper strata brake equipment 4b, 4d time, also the material that friction coefficient can be selected larger than the friction coefficient of the brake component 41 of upper strata brake equipment 4b, 4d as the material of the brake component 42 of lower floor brake equipment 4a, 4c, and also can be set as M1 < M2.
In the above-described embodiments, enumerate the spread configuration example of two brake equipments 4 in the vertical direction, but also can be increased to the brake equipment 4 of 3, more than 4 or 4 as required.
