When changing the operation of these flooring element 20 postures, at first will mention with the free end side (being positioned at downside under receiving state) that the portion's perisporium 26 of standing constitutes the portion of standing 25 of one, be that center of turn makes the portion of standing 25 rotate towards the clockwise direction of Fig. 4 with bolt 55.Thus, the strut bar 22 that the rotation axial region 56 of upper end is supported on the strengthening rib member 32 of flooring element 20 is raised, and the card of lower end ends axial region 57 near supporter 51 sides, makes its card end axial region 57 cards and ends in the notch portion 60 of supporter 51.At this moment, after card ended axial region 57 and enters the depths of notch portion 60, the portion of standing 25 of flooring element 20 was in the state (floor with respect to the elevator hole is the level of state) that intersects vertically with respect to the bearing surface that is supported on the load-carrying element 21 on the stay bearing plate 53.
Then, the Armset member 23 that will be under the state in the portion of the standing perisporium 26 that is accommodated in flooring element 20 is mentioned.Carry out this Armset member 23 mention operation the time, gripping member 45 is applied the power of upwards mentioning, be that center of turn makes Armset member 23 rotate 90 degree towards mentioning direction with the mounting screw 41 that is installed in axle support section 40.Thus, Armset member 23 forms the state that is erected at above the portion of standing 25.Meanwhile or before and after this, be center of turn with bolt 71, make the free end side of two hold-down arms 63,64 rotate 90 degree and make two hold-down arms be in the state of approximate horizontal.And the notch portion 66 that makes the free end side that is arranged on two hold-down arms 63,64 engages with the axial region of bolt 68 on being screwed on pillar component 44 from the top, and carries out fastening to bolt 68.Consequently, Armset member 23 is supported on the flooring element 20 securely by two hold-down arms 63,64, makes Armset member 23 can give full play to the effect of Armset member.
Thus, finish the assembling operation of elevator inspection rack 10, the operating personnel can stand in the portion of standing 25 mainteinance repair object-based device (control panel 9) is carried out upkeep operation.When carrying out upkeep operation, therefore operating personnel's member 23 that can get a grip on the rail when needed can carry out upkeep operation safely.
In addition, owing to being provided with, the portion of the standing perisporium 26 that is provided with to make the perisporium side plate 27,28 that highly improves around the portion 25 of standing, so, by this perisporium side plate 27,28 is moved to a high position, can improve and the further safety that improves the portion 25 of standing by the height that makes the portion's perisporium of standing.
Fig. 8 A to Fig. 8 D is the instruction diagram of method for adjusting height of portion's perisporium 26 of standing.
Need to prove, because the height adjustment that the perisporium side plate 27 of the front portion 26a by the portion's perisporium 26 of standing carries out is the same with the method for the height adjustment that the perisporium side plate 28 of back portion 26b by the portion's perisporium 26 of standing carries out, so the explanation of the height adjustment that carries out at the perisporium side plate 28 of this omission by the back portion 26b side of the portion's perisporium 26 of standing.
Fig. 8 A and Fig. 8 B height adjustment of the portion's perisporium state before implementing of representing to stand.Under this state, pass the end portion that two bolts (eccentric pin) 37,37 that are set in place two through holes 36 on the portion of the standing perisporium side plate 27 outside the front portion 26a of the portion's perisporium 26 of standing lay respectively at the 33a of upright opening portion of two eccentric orfices 33 that are arranged on the 26a of front portion respectively.At this moment, the upper end of perisporium side plate 27 is configured to can not give prominence to towards the top from the upper end of front portion 26a.
State when Fig. 8 C represents the height of the portion's perisporium of standing to be adjusted.In order to form this state, unclamp two nuts 38,38 that are screwed on two bolts 37,37, make perisporium side plate 27 be in the state that can move.After this, perisporium side plate 27 is mentioned, two bolts 37,37 are moved towards the top along the 33a of upright opening portion of two eccentric orfices 33.Thus, form the perisporium side plate 27 shown in Fig. 8 C towards directly over state after moving, remain on the upper part that two bolts 37,37 in two through holes 36 of perisporium side plate 27 move to the 33a of upright opening portion of two eccentric orfices 33 respectively.Consequently, the top of perisporium side plate 27 moves to the position higher than the upper end of front portion 26a, along with perisporium side plate 27 is outstanding towards the top, and the amount that this perisporium side plate 27 of the corresponding rising of height of the portion's perisporium of standing is outstanding upward.
Fig. 8 D height adjustment of portion's perisporium state after finishing of representing to stand.In order to form this state, under the state shown in Fig. 8 C, make perisporium side plate 27 carry out parallel motion towards Armset member 23 sides.At this moment, owing to only need make two bolts 37,37 under the guiding of the 33b of lateral aperture portion of two eccentric orfices 33,33, carry out side travel respectively, so perisporium side plate 27 is moved.Thus, form the perisporium side plate 27 shown in Fig. 8 D, be maintained at the side part that two bolts 37,37 in two through holes 36,36 of perisporium side plate 27 move to the 33b of lateral aperture portion of two eccentric orfices 33,33 respectively towards the state that the side is straight after moving.After this, tighten two nuts 38,38 and perisporium side plate 27 is fastened on the 26a of front portion by 38,38 and two bolts of two nuts 37,37.Thus, perisporium side plate 27 can be remained on the state outstanding, thereby the height dimension of the portion's perisporium of standing can be held in the state of raising towards the top.
At this moment, though bolt 37 and nut 38 fix with lax state because eccentric orfice 33 is formed the L word shape, so bolt 37 obtains the support of the horizontal surface of the 33b of lateral aperture portion.Therefore, bolt 37 has degree of freedom in the horizontal direction, but does not have degree of freedom in vertical direction, so its position can not drop to the position that glides in the 33a of upright opening portion.Thus, can prevent situation generation, and the portion perisporium of standing can be maintained highly high state, thereby can improve the safety of the portion of standing because of forgetting that binding bolt 37 makes that perisporium side plate 27 sinks.
On the other hand, when the height of portion's perisporium is stood in reduction, can the opposite order of operation order by with the above-mentioned raising portion of standing height the time carry out.That is to say, under the state shown in Fig. 8 D, unclamp nut 38, make perisporium side plate 27 be in the state that can move.After this, bolt 37 is moved in the horizontal direction along the 33b of lateral aperture portion of eccentric orfice 33, and make perisporium side plate 27 move to the right-hand member side, form the state shown in Fig. 8 C thus from left end side.After this, bolt 37 is moved towards vertical lower along the 33a of upright opening portion of eccentric orfice 33.Thus, perisporium side plate 27 is changed to the receiving state shown in Fig. 8 B from the deployed condition shown in Fig. 8 C.Then, perisporium side plate 27 is fixed on the state that is accommodated in the portion's perisporium 26 of standing by clamp nut 38.Under this receiving state, make flooring element 20 folding and the elevator inspection rack is accommodated in than on the low position of control panel 9.
