Description

  The present invention relates to a technique for diagnosing the degree of tilt of an elevator platform in an elevator parking apparatus.

  As a general elevator-type parking device, an elevator hoistway is formed in the center of the parking tower, and parking shelves are provided in a hierarchical manner in the left and right spaces of this hoistway, and are placed on the lowermost part of the hoistway. There is something that forms the entrance and entrance and exit. The hoistway is provided with an elevating platform having a substantially rectangular frame structure so as to be movable up and down, so that the vehicle mounting pallet or the vehicle itself is transferred between the elevating platform and each parking shelf. It is configured. In addition, the four corners of the lifting platform are suspended by four sets of wire ropes as suspension ropes. After these four sets of wire ropes are gathered and wound around a driving sheave that is driven to rotate by a lifting and lowering driving unit of a parking tower uppermost machine room via a turning pulley provided at the uppermost part of the hoistway, Further, it is connected to a counterweight on the other end side through a turning sheave.

  In such an elevator-type parking apparatus, one of the shelf pillars surrounding the hoistway is provided with a plate to be detected corresponding to the entrance floor and all the floors of each parking floor, and the elevator base has the detected plate. A non-contact sensor for detecting the plate is provided. And when a raising / lowering stand raises / lowers, a non-contact sensor detects the to-be-detected board, and recognizes the present position of a raising / lowering stand and stops it on the target floor.

  In such an elevator-type parking device, the rails of the elevator platform and the shelf rails of the parking shelf coincide with each other in order to smoothly transfer pallets and vehicles between the elevator platform and the parking shelves on each parking floor. Need to be matched.

  Therefore, a positioning locking device that connects the elevator rail and the parking rack shelf rail in an aligned state may be provided between the elevator and each parking shelf (see Patent Document 1).

  In this positioning locking device, when the lifting platform reaches the target floor and stops, the connecting plate with guide grooves provided at the lower four corners of the lifting platform projects and moves toward the parking shelf. The guide groove is formed in a shape that expands in a substantially V shape on the parking shelf side. When the connecting plate with the guide groove protrudes and moves to the parking shelf side, the engagement roller on the parking shelf side fits in the guide groove. In this way, it is led toward the approximate center. Thereby, the rail of a lifting platform and the shelf rail of a parking shelf are connected in the aligned state.

  According to this positioning locking device, even if the lifting platform is slightly inclined, if the degree of mismatch (height difference) at each corner is within the guide groove opening width (within the differential tolerance), The above connection becomes possible, and smooth transfer of the vehicle or pallet becomes possible.

  In such a parking apparatus, for example, the inclination of the lifting platform is sequentially increased due to the following factors.

  That is, in the elevator type parking apparatus as described above, each wire rope is worn (including broken wires) by long-term use, and the diameter is reduced by elongation.

  In addition, transmission of driving force from the driving sheave to the wire rope is performed by a wedge action when the wire rope bites into the sheep groove. Although the surface of the sheep groove is usually hardened by heat treatment, it will be worn by long-term use. Moreover, the plurality of sheave grooves on which the plurality of wire ropes are individually wound are subject to unbalanced uneven wear due to various factors such as the wear state of the individual wire ropes, the degree of load application, and differences in overall length. It will occur.

  Such unbalanced uneven wear of each sheave groove causes unbalanced wear and elongation of each wire rope.

  Thus, the unbalanced uneven wear of each sheave groove and the unbalanced wear or elongation of each wire rope have a synergistic adverse effect. And when the diameter of the wire rope and the wear of each sheave groove are unbalanced, the sinking amount of the wire rope into the sheave groove becomes unbalanced. In addition, the wire rope may slip in some sheave grooves where the wear is severe. These are all factors that cause the tilt of the elevator.

  A more specific description will be given of the sinking amount of the wire rope into the sheave groove. FIG. 11 shows a state in which the wire rope 110 is wound around the sheave groove 122 of the drive sheave 120. As shown in FIG. 11A, the wire rope 110 is wound around the sheave groove 122 in the initial state. In this state, the diameter of the wire rope 110 is D0, and the sinking amount of the wire rope 110 is h0. On the other hand, as shown in FIG. 11B, when the sheave groove 122 is worn, even when the wire rope 110 is not worn, the sinking amount h1 of the wire rope 110 is smaller than the initial sinking amount h0. Also grows. Further, as shown in FIG. 11 (c), when the wire rope 110 is worn to the diameter D1, even when the sheave groove 122 is not worn, the amount of sinking h2 of the wire rope 110 is the initial sinking. It becomes larger than the quantity h0. Further, as shown in FIG. 11 (d), when the sheave groove 122 is worn and the wire rope 110 is worn to the diameter D2, the sinking amount h3 of the wire rope 110 is the initial sinking amount. It becomes larger than h0. When the sinking amounts h1, h2, h3 of the wire rope 110 are larger than the initial sinking amount h0 as described above, the support position of the lifting platform by the corresponding wire rope 110 is lowered, and as a result, the lifting platform Will lead to a tilt.

  And if the inclination of the lifting platform becomes large until it deviates from the allowable range, the inclination cannot be corrected even by the positioning locking device, and smooth transfer of the vehicle and the pallet cannot be performed.

  Therefore, it is necessary to appropriately check the degree of inclination of the pallet so that the pallet does not tilt out of the predetermined allowable range.

JP 2003-97077 A

  By the way, the pallet may be intentionally set to a predetermined inclination posture at the time of initial setting when the parking apparatus is installed.

The pulse generator 43 is connected to the rotation shaft of the forward / reverse rotation motor 42a, generates a pulse signal corresponding to the rotation amount of the forward / reverse rotation motor 42a (that is, the lift amount of the lifting platform 32), and will be described later. It gives to the parking device control part 50 to do. With this pulse generator 43, the amount of lifting of the lifting platform 32 due to the rotation of the motor 42a can be detected more accurately. The pulse generator 43 is not necessarily connected to the rotating shaft of the forward / reverse rotating motor 42a, and may be connected to the rotating shaft of the drive sheave 44 or the turning sheave 46, for example.

<Tilt adjustment mechanism>
In addition, an inclination adjusting mechanism for adjusting the degree of inclination of the elevator base 32 is incorporated in the elevator base 32.

  FIG. 3 is an enlarged view of a main part showing the tilt adjusting mechanism.

  In other words, the lifting platform 32 has a lifting platform main body 32 a having a rail 33 that can support the pallet 24 movably. A lifting tool 34 is incorporated in each corner of each lifting body portion 32 a, and one end of each wire rope 48 is connected to the lifting tool 34 via a connecting tool 35. The hanging tool 34 is a so-called turnbuckle with a lock nut, and includes a buckle body portion 34c, upper and lower bolts 34a and 34e, and lock nuts 34b and 34d.

  The upper bolt 34a is connected and fixed to one end of the wire rope 48, and the lower bolt 34e is fixed so as to protrude upward at each corner of the elevating main body 32a. These upper and lower bolts 34a and 34e are screwed into the upper and lower portions of the buckle barrel portion 34c. Lock nuts 34b and 34d are screwed into the upper and lower bolts 34a and 34e.

  Then, by adjusting the screwing amounts of the upper and lower bolts 34a and 34e with respect to the buckle body portion 34c, the vertical position of each corner portion of the elevator base body portion 32a with respect to the wire rope 48 can be adjusted. Further, the adjustment state can be maintained constant by tightening the lock nuts 34b and 34d in the adjusted state.

  Further, by adjusting the screwing amount of the bolts 34a and 34e of each lifting tool 34 at the four corners of the lifting platform 32, the vertical position of the four corners of the lifting platform 32 is adjusted, and the tilt of the lifting platform 32 is adjusted. Can be adjusted. That is, the lifting tool 34 provided at the four corners of the lifting platform 32 functions as an inclination adjustment mechanism that adjusts the tilting degree of the lifting platform 32.

  In addition, as a means to adjust the inclination degree of the raising / lowering stand 32, it is not restricted to the structure using the said inclination adjustment mechanism. For example, a mechanism for adjusting the support position of the turning pulley 47 up and down may be provided to adjust the inclination degree of the lifting platform 32, or the length of each wire rope 48 itself may be adjusted. Also good. Further, these adjustments may be performed manually, or may be performed manually or automatically by the power of an actuator such as a hydraulic cylinder or a motor.

<Detection means>
Further, the lifting platform 32 and the support columns 14FR, 14FL, 14RR, and 14RL detect whether each part of the lifting platform 32 has reached a height position corresponding to each parking shelf 20 or a predetermined height position. Various detection means are incorporated.

  First, a configuration for detecting whether or not the elevator platform 32 has reached the height position corresponding to the entry floor 17 (ground floor) and each parking shelf 20 will be described with reference to FIGS. 2, 4, and 5. .

  That is, the detection unit Z01 and the detection unit Z02 are provided at one of the four corners of the lifting platform 32.

  Further, of the support posts 14FR, 14FL, 14RR, and 14RL, the support posts 14RR corresponding to the detection units Z01 and Z02 are placed at the height positions (each floor height position) corresponding to the entry floor 17 and the parking racks 20. Detected plates ST01 and ST02 are provided as detected elements. The detection plates ST01 and ST02 correspond to the detection units Z01 and Z02, respectively. As the lifting platform 32 moves up and down, the detection unit Z01 detects the detection plate ST01 when passing the height position corresponding to the detection plate ST01, and the detection unit Z02 detects the detection plate ST02. The detected plate ST02 is detected when passing through a height position corresponding to.

  The detection units Z01 and Z02 are provided to be shifted up and down by a predetermined amount in such a manner that the detection unit Z01 is downward and the detection unit Z02 is upward. While the elevator 32 is moving up, the detection unit Z01 detects the detected plate ST01 at a timing after the detection unit Z02 detects the detected plate ST02. As a result, when the rising platform 32 is stopped at a predetermined floor, the detection unit Z02 decelerates at the timing when the detection plate ST02 is detected, and then the detection unit Z01 restarts at the timing when the detection unit Z01 detects the detection plate ST01. Deceleration is performed so that the lifting platform 32 is gently stopped. Similarly, during the lowering of the lifting platform 32, the detection unit Z02 detects the detection plate ST02 continuously at a timing after the detection unit Z01 detects the detection plate ST01. As a result, when the descending elevator platform 32 is stopped at a predetermined floor, the detection unit Z01 decelerates at the timing when the detected plate ST01 is detected, and then restarts at the timing when the detection unit Z02 detects the detected plate ST02. Deceleration is performed so that the lifting platform 32 is gently stopped.

  The parking device control unit 50, which will be described later, controls the driving of the motor 42a in accordance with the detection timing of the detection plates ST01, ST02 by the detection units Z01, Z02, so that the elevator 32 is placed on the entrance floor 17 or predetermined parking. The rack 20 is raised and lowered to stop.

  Next, a configuration for detecting whether or not each part of the lifting platform 32 has reached a predetermined height position will be described in relation to a configuration for diagnosing the degree of inclination of the lifting platform 32.

  First, of the four corners of the lifting platform 32, the one corner portion is set as a reference portion, and the other three corner portions are set as comparison target portions.

  In addition, the setting aspect of a reference | standard site | part and a comparison object site | part is not restricted to the said example, One place in the raising / lowering stand 32 is set to a reference | standard part, and at least one other place except the said reference | standard part among the raising / lowering stands 32 is compared. What is necessary is just to be set to the object part.

  However, in order to more accurately diagnose the degree of inclination, it is preferable that the reference site and the comparison target site are located as far as possible, for example, set at one end portion and the other end portion in the longitudinal direction of the lifting platform 32. It is preferable that

  Further, the reference portion is preferably provided at a position corresponding to the shortest wire rope 48. As a result, the influence of elongation of the wire rope 48 can be eliminated as much as possible, the amount of lifting of the lifting platform 32 can be determined, and the tilted state of the lifting platform 32 can be determined relatively accurately.

  Here, as described above, the detection units Z01 and Z02 are provided at the reference portion which is one corner portion of the lifting platform 32. In addition, a detection plate STB01 having the same configuration as the detection plate ST01 is provided as a detection element on the support column 14RR corresponding to the raised position detection unit Z01. Here, the detected plate STB01 is provided between the entrance floor 17 and the parking shelf 20 on the second floor. The detected plate STB01 has a plate-like portion having a predetermined width in the vertical direction. When the detection unit Z01 detects the plate STB01 to be detected, an on signal for inclination determination is obtained. Here, the timing at which the detection unit Z01 detects the detection plate STB01 and rises to the ON state while the elevator 32 is moving up is a reference in which the reference portion of the elevator 32 passes the predetermined reference height position H1. It is timing. That is, the height position of the reference portion of the lifting platform 32 in this state is the reference height position H1. In other words, when the reference part of the lifting platform 32 reaches the reference height position H1, the detection unit Z01 is turned on and the arrival of the reference part at the reference height position H1 is detected. ing.

  In addition, detection plates STB3, STB4, and STB5 are provided as detection elements in comparison target portions that are the other three corners of the four corners of the lifting platform 32. In addition, detection sections Z3, Z4, and Z5 are provided on the columns 14FR, 14FL, and 14RL corresponding to the detected plates STB3, STB4, and STB5. Here, the detected plates STB3, STB4, STB5 are provided between the boarding floor 17 and the second floor above the ground.

  The detected plates STB3, STB4 and STB4 have a predetermined width dimension in the vertical direction. When the detection units Z3, Z4, and Z5 detect the plates to be detected STB3, STB4, and STB5, an on signal for inclination determination is obtained. Here, in the middle of ascending / descending stage 32, the detection units Z3, Z4, Z5 detect the detected plates STB3, STB4, STB5 and rise to the ON state. This is a comparison target timing that passes the comparison target height position H2. That is, the height position of each comparison target part of the lifting platform 32 in this state is the predetermined comparison target height position H2. In other words, when each comparison target part of the lifting platform 32 reaches a predetermined comparison target height position H2, the outputs of the detection units Z3, Z4, Z5 are turned on, and the comparison target heights of the respective comparison target parts are turned on. The arrival at the position H2 is detected. The comparison target height position H2 may be different from the reference height position H1.

  In the present embodiment, the detection unit Z01 and the detected plate STB01 function as a first detection unit that detects a reference timing at which the reference portion of the lifting platform 32 passes the predetermined reference height position H1. Yes. In addition, the detection units Z3, Z4, Z5 and the detection plates STB3, STB4, STB5 detect the comparison target timing at which each comparison target part of the lifting platform 32 passes each predetermined comparison target height position H2. It functions as a detection means.

  Further, a position that should be above the reference height position H1 and each comparison target height position H2 is set as a tilt degree diagnosis stop position H3. The inclination degree diagnosis stop position H3 is set, for example, at a position where the detection unit Z01 and the detection units Z3, Z4, and Z5 are all turned on, or at a position where the elevator 32 is on the upper floor, here the second floor. . During the teaching process and the inclination degree diagnosis process described later, the lifting platform 32 stops at this inclination degree diagnosis stop position H3.

  In addition, as a detection part Z01, Z02, Z3, Z4, Z5, the thing of the structure which has a non-contact-type or a contact-type sensor is used. As the sensor, it is preferable to use a non-contact type sensor such as a photoelectric sensor that performs detection based on the presence or absence of light shielding by the detector, or a magnetic sensor that performs detection based on the presence or absence of a magnetic reaction by the detector.

<Description of operation>
The elevator parking apparatus configured as described above performs the storing operation of the vehicle 2 in the same manner as a conventional general elevator parking apparatus. That is, at the time of warehousing, the elevator platform 32 on which the pallet 24 is mounted is lowered to the entry floor 17 where the vehicle 2 is placed on the pallet 24. And the vehicle 2 is transferred with the pallet 24 to the parking shelf 20 of the said floor | bed with the raising / lowering stand 32 raised to the predetermined floor. At the time of delivery, the vehicle 2 stored in the parking shelf 20 on the predetermined floor is transferred together with the pallet 24 to the lifting platform 32, and then the lifting platform 32 is lowered to the entry floor 17. Then, the vehicle 2 is taken out of the parking tower 10 from the pallet 24. Since these entering / exiting operations are well known in the art, a detailed description thereof is omitted here.

  This elevator type parking apparatus has a function of performing an inclination degree diagnosis process for the elevator platform 32 in addition to the above-described entry / exit process of the vehicle 2, and the inclination degree diagnosis process will be described in more detail.

  First, in performing the tilt degree diagnosis process of the elevator platform 32 in this elevator type parking apparatus, it is necessary to perform a teaching process in advance, and the teaching process will be described.

  FIG. 7 is a flowchart showing the teaching process.

  First, the power on / off key switch 81 is switched to the “on” state, the operation mode switching switch 82 is switched to the “maintenance / inspection mode”, and the diagnostic mode switching switch 83 is switched to the “gradient degree diagnostic mode”. In the initial state, the lifting platform 32 is in a state of landing on the boarding floor 17 without mounting the pallet 24. In this state, all the detection units Z01 and Z02 of the lifting platform 32 are in the on state, and the lifting platform 32 is locked on the boarding floor 17. Furthermore, the entrance / exit floor 17 is unmanned and the entry / exit door is also closed. In addition, the inclination degree of the lifting platform 32 is set within a range of inclination degrees that causes no problem in operation by manual work by an operator. The initial posture of the lifting platform 32 is not necessarily a horizontal posture, and may be a tilted posture within a range where there is no problem depending on the characteristics of the parking device.

  In this state, a command (initial setting command) for giving the teaching process is given via the input key 84 or the like. Then, the following processing is executed under the control of the parking device control unit 50. That is, in step S1, it is determined whether or not the lifting platform 32 exists at the origin position (in this embodiment, the ground floor which is the entrance floor is the origin floor) based on the detection outputs from the detection units Z01 and Z02. Is done. Here, if it is determined that the lifting platform 32 is not present on the origin floor, the process proceeds to step S8, the lifting platform 32 is moved to the origin floor, and the process returns to step S1. If it is determined in step S1 that the lifting platform 32 exists on the origin floor, the process proceeds to step S2.

  Note that the origin floor does not have to be the entrance floor. For example, an origin sensor is additionally provided in the vicinity of the entrance floor or other places, and when it is detected that the elevator 32 has reached a predetermined height position through the origin sensor, the elevator 32 is brought to the origin position. It may be determined that there is a reset (return to origin).

  In step S <b> 2, the parking device control unit 50 resets the number of pulses of the pulse generator 43. As a result, the number of pulses in the pulse generator 43 is counted based on the state in which the elevator platform 32 is on the origin floor. Note that the timing at which the parking device control unit 50 resets the number of pulses of the pulse generator 43 is more specifically, for example, the timing at which the detection unit Z01 detects the detection plate ST01.

  Then, it transfers to step S3 and the parking apparatus control part 50 cancels | releases the lock | rock of the lifting platform 32, and moves the lifting platform 32 from the origin floor toward the inclination degree diagnosis stop position H3.

  Then, the detection units Z01 and Z02 are all turned off. Then, when the lifting platform 32 reaches the reference height position H1 and the vicinity of the comparison target height position H2, the detection units Z01, Z3, Z4, and Z5 are sequentially turned from the off state to the on state. In step S4, the number of pulses P01, Pm3, Pm4, and Pm5 at the timing when each of the detection units Z01, Z3, Z4, and Z5 is turned on are stored in the storage unit 51, and the process proceeds to step S5.

  Here, when the lifting platform 32 is adjusted in a substantially horizontal posture, the pulse numbers P01, Pm3, Pm4, and Pm5 are substantially the same. On the other hand, when the lifting platform 32 is adjusted in a predetermined inclination posture, the number of pulses P01, Pm3, Pm4, and Pm5 varies according to the predetermined inclination posture as shown in FIG.

  In step S5, the lifting platform 32 is stopped at the inclination degree diagnosis stop position H3.

  In the next step S6, it is determined whether or not all of the detection units Z01, Z3, Z4, and Z5 are in an on state, and if it is determined that all of the detection units Z01, Z3, Z4, and Z5 are not in an on state, In step S9, it is determined that teaching has failed. In the case of teaching failure, the teaching process may be repeated again, or it may be indicated to the operator or the like to prompt the readjustment. On the other hand, if it is determined that all of the detection units Z01, Z3, Z4, and Z5 are on, the process proceeds to step S7.

  In step S7, the number of pulses P3, P4, P5 is obtained based on the following formulas P3 = Pm3-P01, P4 = Pm4-P01, P5 = Pm5-P01, and these are stored in the storage unit 51. These pulse numbers P3, P4, and P5 are values indicating the amount of elevation of the elevator 32 between the reference timing and the comparison target timing at the time of teaching execution (initial setting). The inclination state is also shown.

  Teaching is completed as described above.

  Next, the inclination degree diagnosis process of the lifting platform 32 will be described. FIG. 9 is a flowchart showing the inclination degree diagnosis process.

  First, the power on / off key switch 81 is switched to the “on” state, the operation mode switching switch 82 is switched to the “maintenance / inspection mode”, and the diagnostic mode switching switch 83 is switched to the “gradient degree diagnostic mode”. The initial state is the same as the initial state in the teaching process.

  In this state, a command is issued to start the tilt degree diagnosis process via the input key 84 or the like. Then, processing similar to steps S1 to S3 and S8 in the teaching processing is executed.

  Then, in step S14 following step S3, the pulse numbers P01a, Pm3a, and Pm3a of the pulse generator 43 at the timing when the detection units Z01, Z3, Z4, and Z5 corresponding to the respective comparison target parts of the lifting platform 32 are turned on. Pm4a and Pm5a are stored in the storage means 51.

  Thereafter, processing similar to steps S5 and S6 in the teaching processing is executed. If it is determined in step S6 that all the detection units Z01, Z3, Z4, and Z5 are not in the on state, the process proceeds to step S19, and it is determined that the diagnosis has failed. In the case of a diagnosis failure, the diagnosis process may be repeated again, or a visual inspection or the like may be promoted by showing the fact to an operator or the like. On the other hand, if it is determined that all of the detection units Z01, Z3, Z4, and Z5 are in the on state, the process proceeds to step S17.

  In step S17, based on the following formulas P3a = Pm3a-P01a, P4a = Pm4a-P01a, P5a = Pm5a-P01a, the number of pulses P3a, P4a, P5a indicating the ascending amount of the lifting platform 32 is obtained, and these are stored in the storage unit 51. Remember me. These pulse numbers P3a, P4a, and P5a are values indicating the amount of elevation of the elevator 32 between the reference timing and the comparison target timing at the time of diagnosis execution, and also indicate the inclination state of the elevator 32. Yes. Here, if the tilt posture of the lifting platform 32 is substantially the same as the tilt posture in the initial state, the pulse numbers P3a, P4a, and P5a are substantially the same as the pulse numbers P3, P4, and P5 in the initial state. On the other hand, when the tilting posture of the lifting platform 32 is significantly different from the tilting posture in the initial state, the pulse numbers P3a, P4a, and P5a deviate from the pulse numbers P3, P4, and P5 in the initial state as shown in FIG. Value.

  In the next step S21, it is determined whether or not the pulse numbers P3a, P4a, and P5a are within the allowable lift ranges P3 ± α, P4 ± α, and P5 ± α that are determined based on the pulse numbers P3, P4, and P5. Determined. If the number of pulses P3a, P4a, P5a is the same as the upper limit value or lower limit value of the allowable lift range P3 ± α, P4 ± α, P5 ± α, either YES or NO is determined. May be.

  If it is determined that the number of pulses P3a, P4a, P5a is within the allowable range of elevations P3 ± α, P4 ± α, P5 ± α, the process proceeds to step S22 and a pass determination is made. And it is displayed on the display part 85 that it is a pass determination, for example, and a diagnostic process is complete | finished.

  On the other hand, if it is determined that the number of pulses P3a, P4a, P5a is out of the allowable lift range P3 ± α, P4 ± α, P5 ± α, the process proceeds to step S23, and a failure determination is made. The diagnostic process is terminated by displaying, on the display unit 85, the fact that the tilt degree of the lifting platform 32 needs to be adjusted.

  When a failure determination is made in step S23, the maintenance staff who recognizes the adjustment adjusts the degree of inclination of the elevator platform 32. For example, the maintenance person opens the entry / exit door and manually raises the lifting platform 32 from the entry floor 17 to a predetermined height position. At that position, the tilt adjustment mechanism of the corner portion out of the range of the reference values P3 ± α, P4 ± α, and P5 ± α among the four corners of the lift 32 is manually adjusted, and the lift 32 To a predetermined initial posture. At this time, when the shifted corner portion of the lift 32 is specified and the shift amount (number of pulses P3a, P4a, P5a) is displayed, the lift 32 is adjusted by an amount corresponding to the shift amount. Is returned to a predetermined initial posture.

  According to the elevator type parking apparatus and the tilting degree diagnosis method configured as described above, first, the state detection of the first and second detection means, the pulse generator 43, etc. is performed at the time of teaching, which is the initial setting time. The number of pulses P3, P4, and P5 indicating the amount of lifting of the lifting platform 32 between the reference timing and the comparison target timing are acquired as values indicating the tilt state of the lifting platform 32 through the means. Further, at the time of tilt degree diagnosis, the pulse numbers P3a, P4a, and P5a indicating the amount of lifting of the lifting platform 32 between the reference timing and the comparison target timing through the state detection means are used as values indicating the tilting state of the lifting platform 32. Have acquired. Then, the degree of inclination of the lifting platform 32 is diagnosed by evaluating the number of pulses P3a, P4a, and P5a at the time of inclination degree diagnosis with reference to the number of pulses P3, P4, and P5 at the time of teaching. For this reason, it is possible to easily and accurately diagnose the inclination degree of the lifting platform 32 on the basis of the inclination degree of the lifting platform 32 at the initial setting without manually inputting the tilt state of the lifting platform 32.

  This effect will be described more specifically. That is, depending on the installation mode of the elevator parking apparatus, it may not be preferable that the lifting platform 32 is completely horizontal in the initial state. For example, in a certain type of elevator apparatus, it has been empirically found that the elongation amount of a specific one of the four wire ropes 48 that suspend the lifting platform 32 is larger than the others. For example, the wire rope 48 that suspends the lifting platform 32 at a position farther than the lifting drive device 40 on the entrance / exit side has a relatively large amount of elongation. In such a case, the position of the portion suspended by the predetermined wire rope 48 that is expected to be large in the suspended portion of the lifting platform 32 is allowed to be higher than the other positions. The lifting platform 32 is tilted within the range of the tilted degree.

  Then, at the time of initial setting such as when an elevator parking device is newly installed or renovated, the teaching process is executed in a state where the elevator platform 32 is tilted within the allowable tilt range as described above. As a result, the allowable lift ranges P3 ± α, P4 ± α, and P5 ± α are determined in a state where the lift 32 is tilted.

  At this time, the lower limit value of the allowable elevation range P3 ± α, P4 ± α, P5 ± α corresponding to the predetermined wire rope 48 that is easy to extend is set smaller than the others. By performing the diagnosis process in this manner, even when the predetermined wire rope 48 is relatively extended, it is possible to maintain the state where the lifting platform 32 is within the allowable inclination range for a long period of time. It will be possible.

  Thus, when the initial state of the elevator platform 32 is set to a predetermined inclination state, in order to appropriately diagnose the state of the inclination state of the elevator platform 32 according to the actual installation state of the elevator type parking apparatus, the inclination state It is necessary to make a diagnosis based on this. Then, it is necessary to set the inclination state at the time of initial setting by some means. In this case, assuming that the tilt state of the lifting platform 32 is manually input, the input itself is time-consuming and an input error may occur. Therefore, by acquiring the tilted state of the lifting platform 32 through the first detecting means, the second detecting means, the state detecting means such as the pulse generator 43 and performing the above diagnosis, it is possible to prevent troubles and mistakes in manual input. Thus, the degree of inclination of the lifting platform 32 can be diagnosed easily and accurately.

  In addition, as a state detection means for acquiring the tilt state of the lifting platform 32, various devices such as a well-known tilt sensor or a combination of a plurality of distance measuring sensors can be assumed. In the present embodiment, a first detection unit including a detection unit Z01 and a detection plate STB01, a second detection unit including detection units Z3, Z4 and Z5 and detection plates STB3, STB4 and STB5, and a pulse generator Based on the output from 43, the parking device control unit 50 obtains the lifting amount (number of pulses P3, P4, P5, P3a, P4a, P5a) of the lifting platform 32 between the reference timing and the comparison target timing. Is used as a value indicating the tilted state of the lifting platform 32. For this reason, it is possible to diagnose the inclination state by acquiring the inclination state of the lifting platform 32 relatively accurately with a relatively simple configuration using the position sensor.

  Further, the parking device control unit 50 determines the allowable lift ranges P3 ± α, P4 ± α, P5 ± α on the basis of the number of pulses P3, P4, P5 of the lifting platform 32 during teaching, and at the time of tilt degree diagnosis When it is determined that the number of pulses P3a, P4a, and P5a of the lifting / lowering platform 32 is outside the range of the allowable lifting / lowering amounts P3 ± α, P4 ± α, and P5 ± α, the inclination degree rejection determination of the lifting platform 32 is output. Therefore, it can be automatically diagnosed whether the tilting degree of the lifting platform 32 is acceptable.

  The tolerance α for the number of pulses P3, P4, and P5 may be the same value for each comparison target site, or may be a different value for each comparison target site. Further, the difference in the upper limit direction and the difference in the lower limit direction may be set separately around the number of pulses P3, P4, and P5. This α is based on the type of elevator parking device, the number of units accommodated, the type of vehicle to be accommodated, whether it is a tower type or a structure built in a building, whether the pallet 24 is a swivel type, etc. Depending on empirical, experimental and theoretical settings.

  The lifting platform 32 is formed in a substantially square shape in plan view, and the first detection means including the detection unit Z01 and the plate to be detected STB01 uses one of the four corners of the lifting platform 32 as the reference portion. The second detection means that detects the reference timing and includes the detection units Z3, Z4, Z5 and the detected plates STB3, STB4, STB5 is at least one of the other three of the four corners of the lifting platform 32. The comparison target timing is detected by using (all other three corners here) as the comparison target part. For this reason, the degree of inclination can be diagnosed more accurately by comparing each corner of the lifting platform 32 as a target.

<Modification>
In the present embodiment, the first detection means includes a detection unit Z01 provided on the lifting platform 32 and a detection plate STB01 provided on the support column 14RR. It may be provided in the position. In addition, the second detection means is configured to include detected plates STB3, STB4, STB5 provided on the lifting platform 32 and detection units Z3, Z4, Z5 provided on the columns 14FR, 14FL, 14RL. However, these may be provided at opposite positions.

  In the present embodiment, the origin floor (position) that is the origin of the pulse count is set to the first floor, the reference height position H1 corresponding to the detected plate STB01, and the comparison target height corresponding to the detection units Z3, Z4, and Z5. In the example, the position H2 is set between the first floor and the second floor of the parking shelf 20 (the second floor above the ground), and the inclination degree diagnosis stop position H3 is set on the second floor of the parking shelf 20 (the second floor above the ground). It is not necessary, and these can be set as appropriate, for example, between a specific floor and between floors.

  For example, in an upper entry type parking device or an intermediate entry type parking device in which the vehicle entry floor is set above the first floor, the origin floor may be set to a floor of two or more floors as the entry floor. . Further, in these cases, the reference height position H1 and the comparison target height position H2 can be set immediately above or below the entrance floor that is the origin floor, or between them and the origin floor. Thereby, the amount of movement of the lifting platform 32 can be reduced, and teaching processing and diagnostic processing can be performed quickly.

  Further, the inclination degree diagnosis stop position H3 may be set to a position where it is assumed that the lifting platform 32 that has originated from the origin floor exceeds the reference height position H1 and the comparison target height position H2.

  Further, when the reference height position H1 corresponding to the detected plate STB01 is set to an appropriate floor position such as the second floor, the detected plate ST01, which is an existing facility for raising and lowering the lifting platform 32, is provided. And there exists an advantage that the detection part Z01 can be used as a 1st detection means.

  In the present embodiment, the inclination degree diagnosis of the elevator platform 32 is performed based on the number of pulses P3, P4, P5, P3a, P4a, and P5a. For example, the number of pulses P3, P4, P5, and P3a , P4a, P5a may be multiplied by a predetermined coefficient k to convert the rising amount of the lifting platform 32 into a value more directly indicating the above diagnosis. Here, the predetermined coefficient is a coefficient indicating the amount of lifting of the lifting platform 32 per pulse, and is a value obtained theoretically or experimentally.

  In the above embodiment, the maintenance staff operates the operation panel 80 in the parking tower 10 to execute the inclination degree diagnosis process. However, the above processes are performed by remote operation via the communication network 92. You may make it let. That is, a command for performing a tilt degree diagnosis process by designating the date and time is input through a remote maintenance computer 94 or a portable terminal 96 in an external remote maintenance center or the like. The designated date and time is preferably set within a non-operating time zone in which the user is assumed not to use such as midnight. And the parking apparatus control part 50 performs the diagnostic process of the inclination degree at the designated date.

  This diagnosis result is printed by a printer and provided to maintenance personnel at a later time, or is provided to maintenance personnel from the communication network 92 through the portable terminal 96, for example. This makes it possible to omit the procedure of instructing and executing the inclination degree diagnosis process when the maintenance staff performs the periodic maintenance work of the elevator parking apparatus, and the maintenance work can be performed in a short time.

  The diagnosis result is provided from the communication network 92 to the remote maintenance computer 94, for example. Then, at the remote maintenance center, it can be used for the purpose of creating a maintenance plan such as whether the center maintenance staff can continue operation based on the diagnosis result or whether a repair plan is necessary.

  In addition, the entry / exit door may be open at the stage of executing the inclination degree diagnosis process. Moreover, you may make it perform a diagnostic process by raising / lowering the raising / lowering stand 32 by manual operation. When the entry / exit door remains open, it is convenient for performing diagnostic processing while visually monitoring the lifting / lowering state of the lifting / lowering platform 32.
