Guide rail determines size, chemical component, engineering properties etc. essentially according to specification, but processing method is not especially true
It is fixed, it is determined by each manufacturer.By guide rail be processed into as defined in size when, in cutting, broach or scrape processing etc. before process
Later, surface processing is carried out using grinder.In general, when carrying out plastic processing to metal material, as the degree of deformation increases
Add, the resistance relative to deformation increases, and is hardened compared with the material for being not affected by deformation.This processing is referred to as processing hardening.This with
Line defect in the guide rail crystal referred to as to misplace is related.The hardness of metal is determined by the mobile difficulty of dislocation, if dislocation is difficult
With movement, then illustrate metallic hard.The dislocation increasing when being plastically deformed increasing, accumulates and staggered dislocation is difficult to move, result
It is that metal is hardened.
Therefore, the hardness of machined surface is determined by carrying out the plastic deformation of much degree in processing.Due to processing side
Method or condition are set alone such as cutting speed, cutting output, grinding method, grinding material by each manufacturer, therefore plasticity becomes
There is difference in the variation of shape amount, surface hardness.Moreover, more towards the deep of guide rail and hardness is gradually lower, deeper region not
The hardness number for being plastically deformed and showing raw material itself, therefore become the value of somewhat constant.Depth relative to guide rail
Difference of hardness be presented on surface nearby become larger and the trend that becomes smaller in deep.
When guide way hardness difference, brake component changes with frictional force, coefficient of friction caused by guide rail.When guide rail becomes
When hard, frictional force, coefficient of friction reduce.This is because the real contact area a when guide rail is harder, between guide rail and brake component
Reduce.When the shearing force of per unit area is set as s, frictional force F is indicated by F=a × s.Therefore, when contact area a is smaller
When, frictional force F becomes smaller, therefore coefficient of friction is also smaller.
The specification of emergency braking device, which is determined, falls into defined deceleration using after identical brake component progress test of many times
The case where spending.Deceleration becomes smaller with the decline of spring force and coefficient of friction.
The decrease reason of spring force is caused by the abrasion of brake component, therefore in the prior art, and brake component is set as appropriate
Hardness ensure wear resistance, so that the decline of spring force be inhibited to a certain degree.On the other hand, as coefficient of friction
One of decrease reason, since unevenly adhesion has guide rail bits in the brake component test for the first time, second
Become unstable with the abutting state of guide rail in secondary test.In addition, bits adhering layer is softer compared to brake component, therefore, with guide rail
Occlusion is weaker, is cut in guide rail surface with being unable to fully.Therefore, in second of test, become and led with high hardness
Friction near track surface, therefore coefficient of friction reduces.Especially in the low specification of normal speed, braking distance is short, above-mentioned
Phenomenon is easy to become significant.As a result, defined deceleration may be unable to ensure in test of many times.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of elevator for having following emergency braking device, emergent stopping dresses
Also it is able to maintain that coefficient of friction changes small and stable braking characteristic even if setting and identical brake component being used for multiple times.

To downside position, and the slot for being formed on the direction substantially orthogonal with guide rail and extending in the horizontal direction of sliding surface
Upper surface.The sliding surface of brake component forms convex surface relative to guide rail in vertical direction, and the second sliding position is pushed up in protrusion
Near point, which has the more of the processing hardening portion for excavating the guide rail surface on the rubbing surface of brake component
A protrusion and the edge for reaming the processing hardening portion and extending transversely, the edge are located on the falling direction of the carriage
Than the position of the protrusion downstream, also, the rubbing surface of brake component is convex surface, margin location relative to guide rail longitudinal direction

As shown in Figure 1, emergency braking device is set to such as pit on the descent direction in the lifting direction of carriage, and phase
For two guide rails being arranged in lifting channel wall and it is independently installed.
Fig. 4 is the figure for illustrating the firmness change degree of the depth direction relative to guide rail.The hardness of guide rail 15 is shown in table
Face is high and with going deep into depth direction and trend that hardness is lower.This is as caused by processing hardening above-mentioned.In the situation
Under, because of the processing method of the guide rail of processing and manufacturing quotient or the factors such as difference of condition, change the amount of plastic deformation of guide rail surface,
To which there is difference in hardness.For the processing hardening portion, although there are several differences, for 0.04 from guide rail surface~
The slightly depth of 0.1mm or so, herein in above deeper region, what is be not plastically deformed and show raw material itself is hard
Angle value becomes the value of somewhat constant.In addition, the difference of hardness of the depth relative to guide rail shows big near surface and becomes in deep
Small trend.In addition, hardness is gradually got higher, not shown to this with the another side (back side) close to guide rail.
Next, being compared on guide rail depth direction to difference of hardness.The hardness of depth location D1 is being set as H4, is being incited somebody to action
The hardness of depth location D2 is set as H3, the hardness of depth location D3 is set as to H2, the hardness of depth location D4 is set as to H1 and will
When the difference D2-D1 of depth location is set as equal with D4-D3, the difference of hardness H4-H3 of depth D2 and D1 and depth D4's and D3
Relationship between difference of hardness H2-H1 becomes H4-H3 > H2-H1.That is, the surface away from guide rail is deeper, amount of plastic deformation is more sharp
The hardness number for reducing and showing raw material itself, therefore, even if generating the difference of identical depth location, in the hardness of surface side
Difference also becomes larger, and also becomes smaller in the difference of hardness of deep side.
Fig. 5 shows the main view of the brake component of the comparative example of the brake component relative to the present embodiment shown in Fig. 2.With this reality
The brake component for applying example is compared, and the brake component of comparative example is the braking that transverse edge is not present and is only formed with protrusion 3 in rubbing surface
Part.If brake component is equipped on emergency braking device to adjust spring force, rub as defined in performance between brake component and guide rail
Power is wiped, obtains defined deceleration in first time test.
The figure of cutting process of the first time in guide rail surface when Fig. 6 is brake component of the explanation using comparative example.(a) show
The transverse sectional view of guide rail 8 out.Horizontal axis indicates guide rail width direction and the longitudinal axis indicates guide rail depth direction.It will be than guide rail surface position
It sets deep position and is set as D2.Guide rail section is shown with being simulated in a manner of being divided into processing hardening portion 16 and unhardened portion 17.Processing
Hardening portion 16 becomes the positional relationship than depth D2 depth.
(b) cutting process of guide rail surface when having been rubbed guide rail using brake component is shown.In addition, showing brake component together
The positional relationship that rubs of protrusion 3.Brake component guide rail is pressed on by spring when the state from (a) to rub
When, the protrusion 3 of brake component bites 16 surface of processing hardening portion of guide rail 8, and the processing hardening portion 16 of guide rail 8 is while being cut
Play frictional force.Here, being contacted at longest central location 19 with the processing hardening portion 16 of guide rail 8 in the protrusion 3 of diamond shape,
The cutting depth in the processing hardening portion 16 of guide rail 8 is deep, the left part side 18 of the protrusion 3 of diamond shape and the cutting depth of right part side 20
It shoals.Therefore, the cutting depth of guide rail generates deviation.Although enabling the trend to mitigate by the interval of constriction protrusion 3,
If constriction interval, chip can block slot, so that the chip interferes friction and frictional force (coefficient of friction) is made to become smaller.Therefore, exist
There are the limit for the aspect at reduction interval.
The degree of the cutting depth in the processing hardening portion 16 of guide rail presses on guide rail by the hardness of guide rail, by brake component
Face pressure, brake component contact length influence.When hardness is high, cutting depth is shallow, only rests in the region in processing hardening portion.
Also, causes the deviation of cutting depth when only with protrusion 3, in other words, generate the friction in the region with hardness distribution.I.e.
Just in this way, if adjustment spring force, also can first time test in be provided in deceleration.
The figure of the cutting process of second of guide rail surface when Fig. 7 is brake component of the explanation using comparative example.Carrying out the
Guide rail is using position is not used when second trial, and therefore (a) becomes state identical with Fig. 6.(b) land productivity same as Fig. 6 is shown
Rubbed with brake component guide rail when guide rail surface cutting process.The rubbing surface of secondary brake component, which becomes, to be passed through for the first time
The chip 25 that test is cut guide rail and generated melts the state for being adhered to surface.Brake component is pressed when from the state by spring
When guide rail is rubbed, the protrusion 3 of brake component bites 16 surface of processing hardening portion of guide rail 8, the processing hardening portion 16 of guide rail 8
Frictional force is played while being cut.But the depth bitten is suppressed, only rest on depth D1 compared to first time compared with
Shallow D2.This is because the chip for adhering to brake component counteracts.In general, chip hardness (Guide way hardness) it is less than system
The hardness of moving part.Guide way hardness is also the about half of brake component hardness even by processing hardening.Therefore, brake component surface
Apparent hardness decline and be suppressed the cutting depth of guide rail.
Therefore, when in the chart of the firmness change degree of the depth direction shown in Fig. 4 relative to guide rail apply first
When the hardness of guide rail secondary and in second of test, the difference of hardness of the two becomes D2-D1, and coefficient of friction and the difference of hardness are correspondingly
Decline depending on the situation is possible to that defined deceleration can not be obtained in second of test.
In addition, the abrasion aggravation of protrusion 3, spring force declines and frictional force is made to become smaller, is unable to maintain that when becoming high surface pressure
The braking ability of stipulated number.When increasing the length of brake component, the size of device becomes larger, and is undesirable.
Fig. 8 is first time the cutting in guide rail surface when illustrating the brake component using the emergency braking device of the present embodiment
The figure of cutting method.(a), (b) shows state identical with Fig. 6.(c) it shows and simulates the state after transverse edge 2 rubs
Figure.It rubs when from only there are the states of the deviation of cutting depth in the friction of protrusion 3 shown in (b) to transverse edge 2
When wiping, transverse edge 2 bites the processing hardening portion 16 that the guide rail of the state behind surface is excavated by protrusion 3, is easily accessible to leading
It the deeper position of rail can be in the processing hardening portion for almost reaming guide rail using transverse edge 2 when rubbing in this state
Until depth part while rub.In addition, becoming the braking of convex surface by the way that rubbing surface is arranged in transverse edge
The position most outstanding of part can be cut to so that pressing force when brake component to be pressed on to guide rail becomes larger compared to projection position
Deep D4 more than the processing hardening portion of guide rail.
Fig. 9 is second of cutting in guide rail surface when illustrating the brake component using the emergency braking device of the present embodiment
The figure of cutting method.(a), (b) shows state same as figure 7.In second of test, as noted previously, as chip adheres to
Brake component surface, therefore inhibit biting for protrusion direction guiding rail.(c) it shows and simulates the state after transverse edge 2 rubs
Figure.By adhering to chip on the vertical plane 2a for forming transverse edge, although weakening the effect that bites of transverse edge slightly,
But it can rub while being cut to the processing hardening portion depth neighbouring position D3 for entering guide rail.
Therefore, when in the chart of the firmness change degree of the depth direction shown in Fig. 4 relative to guide rail apply first
When the hardness of guide rail secondary and in second of test, the difference of hardness of the two becomes the difference of hardness D1-D2 in D4-D3, with comparative example
It compares, almost reams processing hardening portion, thus, it is possible to inhibit smaller the difference, can reduce and be tested for the first time with second
Coefficient of friction change.As a result, if being carried out in the mode for becoming the deceleration of first time near prescribed limit median
Spring force adjustment, then the decline of secondary deceleration is smaller, and therefore, it is difficult to be lower than prescribed limit lower limit value.
Figure 10 is to be equipped on the brake component of the brake component of the emergency braking device of the present embodiment and comparative example respectively promptly
The figure of shatter test twice in succession, the down ratio for showing coefficient of friction is carried out after arresting stop respectively.It is with normal speed
90m/min, to fall quality be that 2300kg sets defined spring force, to only with protrusion 3 brake component in convex surface
The brake component that prominent position has transverse edge 2 compares.As a result, by the decline of the coefficient of friction of comparative example 23
When ratio is set as 1, have the frictional decrease in the embodiment 24 of transverse edge 2 be about 0.45 and be suppressed to half with
Under.It should be noted that secondary deceleration has the braking characteristic lower than prescribed limit lower limit value in comparative example 23.
Figure 11 is the main view for showing the emergency braking device of another embodiment of the present invention.In (a), system will be set to
The roller 12a in roller unit 12 between moving part 1 and guiding elements 11 is more configured in the position for being equipped with transverse edge 2.In addition
In (b), the face that the roller unit 12 with guiding elements 11 abuts is set as convex surface 11a, and be set as the widthwise edge of brake component 1
Edge 2 is located near protrusion vertex.Furthermore in (c), divide spring member along the vertical direction, direction guiding rail pressing will be used for laterally
When the spring member 11b at edge is set as the spring bigger than other spring members 11a, 11c, guide rail 8 can be further increased
Machinability, coefficient of friction variation can become smaller.
In addition, reaming the effect in processing hardening portion when having the combination of multiple protrusions and edge that multiple groups illustrate at present
More big, even if implementing test of many times is also difficult to the influence by the chip for adhering to brake component face, coefficient of friction variation can
Become smaller.For example, the emergency braking device of the present embodiment is suitable for being not readily susceptible to the emergent stopping of the influence of the physical characteristic of guide rail
Device.
