The specific embodiment
Explanation is applicable to embodiments of the invention with reference to the accompanying drawings.
Fig. 1 is the constructional drawing of the cage moving limiting device of the lift appliance of expression one embodiment of the invention.Among the figure, the fixed part in the elevating road of for example guide rail etc. is fixed with the fastening plate 21 as stationary member.On fastening plate 21, be provided with connecting hole 21a as the fixation side engagement section.
Being equipped with movable link on the cage 22 of lifting in elevating road is support arm 23.Support arm 23 is can reverse between reception position (Fig. 1) and clamped position (Fig. 3 and Fig. 4) in the center with axle 24.Be provided with the 23a of hook portion of the movable side of the conduct engagement section that engages with the circumference of connecting hole 21a at the leading section of support arm 23.On support arm 23, fixing cam 25 again.
On cage 22, be equipped with the 1st switch 26 by cam 25 operations.The 1st switch 26 has normally closed contact 26a, closure when support arm 23 is in reception position, when support arm 23 is in the way between reception position and clamped position position (Fig. 2) and clamped position by cam 25 operations and open.
Again, although support arm 23 has returned reception position, when normally closed contact 26a can not oneself reset, the 1st switch 26 also can be by the forced closed by the operation of support arm 23 mechanicalnesses.
On support arm 23, be equipped with the 2nd switch 27 by fastening plate 21 operations.The 2nd switch 27 has normal opened contact 27a, opens closure when support arm 23 is in clamped position when support arm 23 is in reception position and the way during position.
Cage 22 lifting by the propulsive effort of actuating device 29.Actuating device 29 is by control setup 30 controls.Control setup 30 comes accessory drive 29 by switching a plurality of operation modes that comprise maintenance pattern on normal mode and the cage selectively.
Again, the 1st switch 26 is because of being connected with safety return circuit (not shown) series connection shape, so in case normally closed contact 26a opens, then interdicted to the energising of actuating device 29.Like this, when support arm 23 is in clamped position, can carry out the running of cage 22, when support arm 23 is in the way position or clamped position, can stop the running of cage 22 by actuating device 29.
But, the by-pass switch (not shown) that on the cage that is provided with cage 22 running usefulness on the cage 22, turns round switch and the bypass loop of the 1st switch 26 short circuits (bypass) is opened and closed.Thus, even when support arm 23 is in clamped position, Yi Bian,, then can carry out the lifting of cage 22 by low speed Yi Bian operate the switch that turns round on the cage if operate by-pass switch with the bypass loop closure.
The following describes action.When support arm 23 is in reception position shown in Figure 1, the 1st switch 26 closures, the 2nd switch 27 is opened.
As shown in Figure 2, in case support arm 23 reverses, then open by cam 25 operations the 1st switch 26, the 1 switches 26.Again, the 2nd switch 27 because of not with fastening plate 21 butts, so open.
As shown in Figure 3, in case support arm 23 arrives clamped position, then the 1st switch 26 is opened, and the 2nd switch 27 is closed by fastening plate 21 operations.
When support arm 23 is in clamped position,, also can be mechanically cage 22 mobile be limited in the scope of connecting hole 21a even the brake equipment of actuating device 29 (not shown) is opened again.For example, under the state of weight greater than cage 22 of balance block (not shown), in case open brake equipment, then cage 22 rises, and as shown in Figure 4, engages the rising that limits cage 22 by the 23a of hook portion with the rising wood of connecting hole 21a.
In above-mentioned lift appliance, when on cage 22, maintaining operation, at first operation mode is switched to maintenance pattern on the cage, make cage 22 low speed move to fixed maintenance position.Thereafter, support arm 23 is reversed to clamped position, the 23a of hook portion engages with the connecting hole 21a of fastening plate 21.Limit moving of cage 22 thus, can on cage 22, maintain operation.
Again, after the maintenance end of job, support arm 23 returns reception position, and operation mode reverts to common operation mode.This moment as shown in Figure 4, when the circumference butt of 23a of hook portion and connecting hole 21a, operate the switch that turns round on above-mentioned by-pass switch and the cage simultaneously, cage 22 is risen slightly or descend, after the position with the relative connecting hole 21a of the 23a of hook portion is back to the position of Fig. 3, support arm 23 is reversed to reception position.
Fig. 5 is the action flow chart in the common operation mode of control setup 30 of presentation graphs 1.In common operation mode, at first, confirm whether support arm 23 is in reception position (step S1).Then, when support arm 23 is not in reception position, stop the running (step S2) of cage 22.Like this, can prevent the collision of support arm 23 and elevating road machine more reliably.
Again, in case after confirming that support arm 23 is in reception position, confirm again whether support arm 23 is in clamped position (step S3).Usually,, then open, so support arm 23 is confirmed to be not on clamped position cage 22 can turn round (step S4) because of the 2nd switch 27 if support arm 23 is in reception position.
But, be in reception position and also detect the occasion that support arm 23 is in clamped position although detect support arm 23, then be judged as switching device 28 fault has taken place, output abnormality detection signal (step S5).
For example, former thereby when being in closure state because of welding etc. as the normal opened contact 27a of the 2nd switch 27, even support arm 23 is in reception position, the 1st and the 2nd switch 26,27 both sides are closed always.In this occasion, the output abnormality detection signal is carried out the repairing or the transposing of switching device 28 by the operator.
Like this, in common operation mode, can confirm whether support arm 23 is in reception position and whether switching device 28 has fault, cage 22 more safely can turn round.
Fig. 6 is the action flow chart in the maintenance pattern on the cage of control setup 30 of presentation graphs 1.On cage, in the maintenance pattern, confirm at first whether support arm 23 is in reception position (step S1).After having confirmed that support arm 23 is in reception position, confirm again whether support arm 23 is in clamped position (step S3).
Be not in clamped position if confirm support arm 23, then be judged as support arm 23 and be in reception position, switching device 28 is also no abnormal, cage 22 can turn round (step S4).Like this, in the maintenance pattern, when support arm 23 was in reception position, cage 22 also can turn round on cage, cage 22 can be moved to fixed maintenance position.
When detecting support arm 23 and be in reception position and clamped position both sides, be judged as switching device 28 faults, output abnormality detection signal (step S5) again.
And, on cage, in the maintenance pattern,, can confirm also whether support arm 23 is in clamped position (step S6) even when detecting support arm 23 not at reception position.Neither during also not at clamped position, then be judged as support arm 23 and be in position in the way when detecting support arm 23, stop the running (step S7) of cage 22 at reception position.
Like this, maintain the position surely in that cage 22 is moved to after, during the operation support arm 23 and support arm 23 really with state that fastening plate 21 engages under, the running of prevention cage 22.Thus, when the operator carried out operation on cage 22, if support arm 23 is not in clamped position, then cage 22 was not carried out lifting.
Again, be not in clamped position, then the OPEN signal (step S8) of the brake equipment of exportable actuating device 29 when stoping cage 22 runnings at reception position in case detect support arm 23.Like this, brake equipment can be opened, and can maintain operation under the state that brake equipment is opened.Again, as mentioned above, if operate the switch that turns round on by-pass switch and the cage simultaneously, then cage 22 can be carried out low-speed running.
Adopt the cage moving limiting device of this lift appliance, because can utilize 28 pairs of support arms 23 of switching device to be in reception position, clamped position and the way which position in the position distinguishes and detects, therefore can control more accurately according to the position of support arm 23, can improve the operation of the maintenance operation on the cage.
Again, owing to used switching device 28, this switching device 28 have when the 1st switch 26 that support arm 23 opens when closure, support arm 23 are in position and clamped position in the way when being in reception position and support arm 23 are in position in reception position and the way open, the 2nd switch 27 of closure when support arm 23 is in clamped position, therefore, available simple structure is distinguished and is detected position in reception position, clamped position and the way.
And, because the 1st switch 26 can return reception position by making support arm 23, the forced closed by support arm 23 operations, therefore, even when the 1st switch 26 can not oneself reset, the 1st switch 26 also can carry out regular event.
Because support arm 23 is provided with the cam 25 that can operate the 1st switch 26 when being in position and clamped position in the way, therefore can operate the 1st switch 26 more reliably again.
Again, because at operation mode is when maintaining pattern on the cage, in a single day control setup 30 detects support arm 23 and is in reception position, just can make cage 22 runnings, be in position or clamped position in the way in case detect support arm 23, then stop the running of cage 22, therefore can more safely on cage 22, maintain operation.
And,, therefore can prevent the collision of support arm 23 and elevating road machine more reliably because when operation mode was common operation mode, in a single day control setup 30 detected support arm 23 not at reception position, then stops the running of cage 22.
Again, owing to send the anomaly detection signal of switching device 28 when the 1st, the 2nd switch 26,27 all is in closure, therefore, the fault that the normally closed contact 26a that can easily detect the 2nd switch 27 welds etc. can improve reliability.
Owing to just detecting the OPEN signal of just exporting brake equipment when support arm 23 is in reception position, therefore can carry out opening of brake equipment more safely again.
And, because when support arm 23 is in clamped position, in case the operation by-pass switch is with the bypass loop closure, then the operation by running switch on the cage can make cage 22 runnings, therefore, even support arm 23 is in clamped position, also can make cage 22 liftings, can easily the fastening state of support arm 23 be removed.
In addition, above-mentioned example is the structure that is fixed in fastening plate 21 in the elevating road and carries support arm 23 on cage 22, but also stationary member can be fixed in cage, and movable link is arranged in the elevating road.
Again, above-mentioned example be the support arm 23 that can reverse as movable link, but also can adopt slidably movable link as shown in Figure 7 and Figure 8.
