In the present embodiment, lowest floor, the length of the stop detection plate 22 of common floor, uppermost storey are distinguished not
Together.The stop detection plate 22 of common floor is set as a certain constant length, lowest floor stretches downwards towards elevator pit, most
High-storey stretches longer towards top plate to top.The length of the stop detection plate 22 of uppermost storey be by aerial size (from
Sizes of the uppermost storey FL to top plate) determine length, when safeguarding top apparatus (not shown) etc., need lift car
8 operating near top, at this point, in the prior art in order to prevent lift car 8 it is excessive traveling and with make its mechanically
The limit switch 109 of stop.Limit switch 109 in order to eliminate the existing technology is set as electric control as electronic security(ELSEC)
The structure of system increases the length for stopping detection plate 22.For lowest floor, from the top of lift car 8
Whens maintenance test control device 16 is equal, it is also desirable to lift car 8 is operated to elevator pit, in order to prevent excessive descent, with
Uppermost storey similarly needs to increase the length for stopping detection plate 22.About uppermost storey, the stop detection plate 22 of lowest floor
Length refer to it is aftermentioned.
It utilizes such structure, in the present embodiment, by electric control, it is minimum can to judge that lift car 8 rests in
Floor is advanced with uppermost storey or excessively, can be without using the limit being made of limit switch 109, limit cam 111 etc.
" anti-locking mechanism of excessively advancing " is set in the case of switching mechanism.
In thus configured lift appliance, spacing bracket 112, the limit of existing composition limit switch mechanism are not needed
Switch 109 and limit cam 111 etc. and manufacturing cost can be reduced, and opened using previous configuration spacing bracket 112, limit
It closes 109 installation space and the reconfigurations of the miscellaneous equipments such as safety device 15, control device 16 and stern fast 18 can be carried out.
According to the present embodiment, abolishes limit switch mechanism as described above and changes the allocation position of floor detection plate,
Thus, it is possible to generate new space.Illustrate the concrete example that miscellaneous equipment is configured in the new space.
Due to the stop inspection for the lifting channel wall 102 that can abolish the right side shown in Figure 20 positioned at lift car 108
Survey device 121, stop detection plate 122, limit switch 109 etc., therefore new space can be obtained in the portion.Thus, it is possible to
By Figure 20 in the prior art be located at lift car 8 back side stern fast 118 as shown in Figure 1 to stop detector 121, stop
Space residing for detection plate 122, limit switch 109 etc. is mobile and is reconfigured stern fast 18.
Moreover, by mobile stern fast 18, occurs new space in the location of script stern fast 118.By efficiently using
The space and the length dimension that balance weight 5 can be increased, therefore the weight of balance weight 5 can be increased.Therefore, by that can increase
The weight of lift car 8, in the case of customer's such as additional optional pattern that cooler is set or floor is changed to steel plate
It is advantageous.In addition, the length of balance weight 5 (guide rail away from) can be changed to length identical with other equipment type, it can
Realize the cost for standardizing and reducing lift appliance.
In addition, configuration is not only stern fast 18 in new space, such as also being capable of mobile controller 16, safety device 15
Deng.Moreover, mobile controller 16, safety device 15 and the space vacated also can further configure stern fast 18, for
The miscellaneous equipments such as the elevator pit staircase (not shown) that elevator pit declines.
Next, master when indicating to extend the stop detection plate 22 of uppermost storey respectively in Figure 11, Figure 12 and Figure 13
View, side view and vertical view.In addition, indicating that the stop for extending lowest floor is examined respectively in Figure 14, Figure 15 and Figure 16
Front view, side view when drafting board 22 and vertical view.First, illustrate the stop detection plate 22 of uppermost storey.
As shown in Figure 11 to Figure 13, the stop detection plate 22 of uppermost storey is stretched towards top plate to top.Fixing means
With it is above-mentioned shown identical, be fixed on the door guide frame 26 of door pocket 24 in the same manner as common floor, but due to stopping detection plate 22
Made aerial size different according to the building including object, therefore in the presence of the length that can not unify stop detection plate 22
Present situation.Therefore, stopping detection plate 22 must increase (because usually aerial size is 3m or so).When increasing, detection plate is stopped
22 are possible to rock back and forth to the left and right.When rocking, it is possible to can not be detected with the disengaging of detector 21 is stopped, or and elevator
Car 8 contacts.For this purpose, this is in the 26 upper mounting plate mounting bracket 33 of door guide frame for being fixed on door pocket 24, in plate mounting bracket
The one end that reinforcer 32 is fixed on 33 is fixed in the end of another party and stops detection plate 22, thus prevents shaking for left and right directions
It shakes.At this point, according to the length for stopping detection plate 22, by the way that the angle of reinforcer 32 is decreased or increased, thus, it is possible to prevent from rocking.
In addition, as shown in figure 13, uppermost storey stop is detected board bracket 34 from lifting channel wall 2 by rocking about the front and rear direction
Or car side rails 3A, 3B take out (example goes out the example taken out from car side rails 3A in the present embodiment) and are fixed on and stop
Near the top portion of detection plate 22, thus, it is possible to prevent in the front-back direction rock.By being set as such construction, even if increasing
Long detection plate 22 of stopping will not rock, and stopping detector 21 can be operating normally.
In this way, increasing uppermost storey side stops detection plate 22 for this purpose, that is, further up in lift car 8
To lift car 8 14 face of car threshold it is higher than the floor face of uppermost storey in the case of, can also be stopped using uppermost storey side
Shading is carried out by detection plate 22, so that the light from the illumination region E for stopping detector 21 can not reach acceptance part R.Thus,
Detection plate 22 is stopped by increasing uppermost storey side, even if making to be located at uppermost storey because balance weight 5 is made to decline for certain reason
Lift car 8 it is further up compared with current uppermost storey position, also can reliably using stop detector 21 come
Detect the excessive traveling of lift car 8, it can be ensured that safety so that lift car 8 will not penetrate the elevator pit of liftway 1
Face.
Next, using Figure 14, Figure 15 and Figure 16 to the lowest floor of lowest floor stop the structure of detection plate 22 into
Row explanation.
In the case where lowest floor stops detection plate 22, as shown in figure 15, lowest floor stops the lower end of detection plate 22
The downside of front surface of the portion by entrance threshold fixing bolt 13A and mounted on entrance threshold 13.In addition, lowest floor is stopped
Extend upward towards the top plate direction of liftway 1 by detection plate 22, to avoid with car threshold 14 and entrance door
It is interfered between sill 13.The upper end that the lowest floor stops detection plate 22 is fixed on by fixing bolt 17A on door pocket 24
Portion, in addition, as shown in figure 14, door pocket 24 is fixed on door pocket mounting bracket 35.Therefore, lowest floor stops the length of detection plate 22
As the length on 24 top of door pocket is crossed from entrance threshold 13, it is configured to longer than uppermost storey side stop detection plate 22.
It is similarly configured to using made of Chong Die U-shaped with uppermost storey moreover, detection plate 22 is stopped in lowest floor side
Between detection plate 22 is stopped to block three floor detectors of stop detector 21 illumination region E and acceptance part R.
Therefore, in the same manner as uppermost storey, increase lowest floor side and stop detection plate 22 for this purpose, that is, in electricity
Terraced car 8 further drop to lift car 8 14 face of car threshold it is lower than the floor face of lowest floor in the case of, also can
Detection plate 22 is stopped to carry out shading using lowest floor side, so that the light from the illumination region E for stopping detector 21 can not
Reach acceptance part R.Thus, detection plate 22 is stopped by increasing lowest floor side, even if making balance weight 5 rise because of certain reason
And the lift car 8 positioned at lowest floor is made further to decline compared with current lowest floor position, it can also pass through stop
Detector 21 reliably detects the excessive traveling of lift car 8, it can be ensured that safety so that lift car 8 will not penetrate liter
The elevator pitted surface in channel 1 drops.
In addition, when increasing lowest floor stop detection plate 22, rigidity is weaker, it is possible to rock, therefore will be minimum
The downside of the front surface of entrance threshold 13 is fixed in the lower end of floor stop detection plate 22, and lowest floor is stopped detection plate 22
It extends to 24 top of door pocket and is fixed, eliminate and rock thus, it is possible to increase the rigidity of lowest floor stop detection plate 22.
So, lowest floor can be inhibited to stop the deformation of detection plate 22, rock, lowest floor is inhibited to stop the screening of detection plate 22
Light portion contacts such interference effect with the illumination region E and acceptance part R for stopping detector 21.
Next, being illustrated for the shape for lowest floor and the stop detection plate 22 of uppermost storey.
As shown in figure 18, by the F views from upper surface it is found that two detection plates 22 for being set as U-shaped are overlapped.Work as sight
It is found that for example there is notch Q in a part for the lower part of the detection plate on right side 22 when examining the front view of Figure 17.It is arranged notch Q's
Position can also be the detection plate of center, the detection plate in left side, in order to not only read the level information of detection plate and go back
Simultaneously read uppermost storey, lowest floor, common floor distinctive information, can be in uppermost storey, lowest floor, common floor
Place is distinguish.Level information of the construction of notch Q between record elevator lobby floor plate and the ground of lift car 8
Meanwhile it as the FLS (end stop switch) for substituting as the limit switch mechanism anti-locking mechanism of excessively advancing, needing
By means of overlapping U-shaped made of stop detection plate 22 come block three stop detectors 21 illumination region E and acceptance part R it
Between structure, will be used for only by floor detection plate carry out electronics (program) detect information be used as a series of continuous letter
Breath.Floor detection device 21 uses three, due to substantially carrying out the building of each floor using two unit floor detection devices
Layer detection, therefore use any two stopped in detector 21.N section equipped with notch Q is for detecting each floor (FL；Ground
Face height), do not have notch from a certain constant size (being in fig. 17 top), in three floor detection devices 21,
Using detection plate 22 to carrying out shading at three, thus enable that the parts M become FLS (end stop switch) detecting system, it can
Prevent the excessive traveling of lift car 8.In addition, when Figure 17 to be set as to the stop detection plate 22 of uppermost storey, lowest floor
With can be by being set as making the state of the state of Figure 17 inverted up and down, in upper left side slit configuration Q, thus to obtain same
System.
Here, the length for stopping detection plate 22 is different because of used floor difference.About stop detection plate 22
Length, as described above, in order to eliminate limit switch 109, in order to use the structure of electric control system as electronic security(ELSEC),
It needs to increase the length for stopping detection plate 22.The length of the detection plate 22 of uppermost storey according to balance weight 5 and buffer (not
Diagram) until size (be known as counterweight run-by), buffer deflection (being known as cushion stroke), protrude into balance weight 5
The assembling of lift car 8 is ascended to heaven upward in the case of buffer size (being known as jump value), in addition to this building itself
Error, to determine the L dimension described in Figure 17.Equally, about the detection plate of lowest floor 22, from the top of lift car 8
Whens maintenance test control device 16 is equal, need, by near the operating to elevator pit of lift car 8, to need to increase in the same manner as uppermost storey
The long length for stopping detection plate 22, therefore car (is known as according to the size until lift car 8 and buffer (not shown)
Run-by), the error (building error) of the deflection (being known as cushion stroke) of buffer, elevator pit depth dimensions, to determine
The L dimension of detection plate 22.
Wherein, the detection plate of lowest floor is prolonged towards the elevator pit ground direction of building in defined length range
It stretches.Increase downward for this purpose, that is, the feelings lower than the floor face of lowest floor are further dropped in lift car 8
Under condition, also detection plate 22 can be stopped to carry out shading using lowest floor side, so that from shining for detector 21 is stopped
The light of portion E can not reach acceptance part R.Thereby, it is possible to reliably detect the excessive row of lift car 8 using detector 21 is stopped
Into, it can be ensured that installation so that lift car 8 will not charge into elevator pit ground.Therefore, as described above, by by lowest floor
The detection plate 22 of layer is fixed on door pocket 24 and entrance threshold 13, without the concern for the length of the detection plate 22 of L dimension, energy
Enough ensure the distance that lift car 8 can decline.Designated length is not needed as a result, and can be achieved at the same time design time yet
Shortening.
In addition, the three one-piece type stop detectors 21 opposed with the stop detection plate 22 of each floor are fixed in elevator
The top of car 8, to keep and stop the mutual position relationship between detection plate 22.Therefore, because stopping detector 21
Itself will not be moved, therefore will not be interfered with the light shielding part for stopping detection plate 22.Even if applying inclined load to lift car 8
And small movement is generated in left-right direction, it is set as to send out with the light shielding part for stopping detection plate 22 by the way that detector 21 will be stopped
The raw such width dimensions (distance from illumination region to acceptance part) of contact, can also avoid the interference of the two.
In this way, being arranged in the upper surface of door pocket 24 and only by fixing bolt 17A, reinforcing plate since detection plate 22 will be stopped
32, uppermost storey is stopped detection board bracket 34, entrance threshold 13 etc. and is fixed, therefore assembling becomes simple.In addition, by
Detection plate 22 is stopped in being fixed as described above using door pocket 24, therefore can accurately acquire installation site, is not needed substantially
Installation site is adjusted, thus, it is possible to shorten built-up time.
Here, compared with the existing lift appliance configured with stop detection plate 122 in tower shown in Figure 20, due to
The stop detection board bracket 123 that floor detection plate 122 is arranged at the fixing component 106B for being fixed on car side rails 103B
End, therefore the assembly error of guide rail 103B is generated, and on the stop detection board bracket 123 for being fixed on fixing component 106B
Generate clearance etc..Moreover, the stop detector 121 for being fixed on lift car 108 must be come by stopping the light shielding part of detection plate 122
Center, it is necessary to from the top of lift car 108 confirm adjustment stop detection plate 122, can not directly on lift car 108 really
Recognize and is adjusted operation.
In contrast, the lift appliance in the present embodiment only carries out installing in the upper surface of the door guide frame 26 of door pocket 24 and stop
By the operation of detection plate 22, therefore assembling operation can be improved, and also reduce the number for stopping detection board bracket 123, energy
Enough reduce the cost of component.For example, in the case of floor more high-rise, needs to install in each floor and stop detection
Plate 22 is also required to identical number for the fixed detection board bracket 123 for stopping detection plate 22, therefore component costs is caused to increase
Add.In the present embodiment, the detection board bracket 34 of uppermost storey be only one, common floor, lowest floor detection plate
Bracket 123 is not necessary, it is achieved that the reduction of component costs.
Finally, the structure that detection plate 22 is stopped to the common floor side of common floor illustrates.Substantially and highest
22 identical structure of detection plate is stopped in floor side, but its length is shorter.Be also about its effect, effect etc. as a result, it is identical, because
The repetitive description thereof will be omitted for this, hereinafter, being illustrated to different structure divisions.
Fig. 8, Fig. 9 and Figure 10 show that detection plate 22 is stopped in the common floor side of common floor.It stops common floor side
Detection plate 22 need not detect the excessive traveling of lift car 8, only obtain the level between floor and the floor of lift car
Information, therefore need not be configured longer as lowest floor stops detection plate 22.Thus, such as need not be by most
The detection plate mounting bracket 34 of high-storey carries out two dot points, can reduce number of components.
In addition, in two stop position detectors 21, the door guide rail of detection plate 22 and door pocket 24 is stopped in common floor side
The cooperation of 26 upper surface side of frame is fixed.In this way, since only common floor side stop detection plate 22 being fixed by fixing bolt 17A
In the detection plate mounting bracket 17 at the door guide frame 26 of door pocket 24, therefore assemble relatively simple.
As described above, signal when by shading is carried out using each light shielding part for stopping detection plate 22 is set as
" 0 ", by not by shading when signal be set as " 1 " when, such as in lowest floor detect the signal of " 100 ", examined in common floor
The signal for measuring " 010 " detects the signal of " 001 " at uppermost storey.In addition, when FLS when uppermost storey, lowest floor
As " 000 ".By sending these signals to control device 16, control device 16 parses these signals, and thus, it is possible to carry out
Lift car 8 is to arrive at lowest floor or arrive at common floor or be the such judgement of arrival uppermost storey.
As a result, due to that can judge that lift car 8 arrives at lowest floor and uppermost storey, become need not use by
" anti-locking mechanism of excessively advancing " can be arranged in the limit switch mechanism of the compositions such as limit switch 109, limit cam 111
System.
According to above structure, can obtain by the way that the structure of limit switch mechanism is replaced by the system for stopping detection plate
To carry out stop detection device and stop the inspection of detection plate, the lift appliance of upkeep operation.
