Description

An embodiment of the present invention relates to a marking plate for elevator remodeling work.

In elevators, various measures are taken to prevent doors from opening. When the car is stopped at the landing, the position of the car is not maintained by mechanical engagement or the like, so that the car may move with the door open. Here, door-opening driving means that the car door of the car is not completely closed and the car moves while it is open. In the conventional door-open running prevention system, the system is constructed so that the door-open state of the car door and the landing position of the car are detected, and if the landing position is deviated, the car cannot move.

In recent door-opening prevention systems, a forced divergence switch has been used as a detector for detecting door-opening of a car door. This forced divergence switch is a switch that closes the circuit when the car door is closed to enable the operation of the elevator, and opens the circuit when the car door is open to prevent the elevator from being operated. By using this forced divergence switch, it is possible to reliably prevent the car from traveling as long as the car door is open.

By the way, when renewing an existing elevator, the old door open detector may be replaced with a forced divergence switch in order to strengthen the measures to prevent the door open running.
The forced dissociation switch is mounted on the car door, but as a preparation before mounting, it is important to mark the position of the bolt hole for mounting and drill the bolt hole at the correct position. If this scribing operation is performed incorrectly, an error will occur in the mounting position of the forced dissociation switch, and in some cases, a series of operations of dimension measurement, scribing, and drilling will have to be redone.

However, when a forced divergence switch is installed in the renewal work, for example, in a car with a single-sided two-door car, the door stop portion of the closed car door becomes a work area. This door stop is sandwiched between the landing door and the landing wall, and the work space is very narrow, so workability is very poor. Workers are forced to work in a working posture, such as leaning out from the car and reaching out. In particular, dimensional measurements performed to determine the position of bolt holes make accurate measurements difficult.
If it was found that the forced divergence switch did not operate normally even if a hole was made with a dimensional error and the forced divergence switch was attached, the dimensional measurement had to be restarted.

The present invention has been made in view of the problems of the prior art, and can eliminate the need for measurement work in a narrow space, streamline the scribing work, and mark the exact position of a screw hole or the like. It is an object of the present invention to provide a marking plate and a marking method for elevator remodeling work.

In order to achieve the above object, the injured plate for elevator modification work according to the embodiment of the present invention is attached to the apex of two right-angled corners at the end of the door hanger or the door machine base of the car. It is an elevator modification work injured plate used to mark the position of the screw hole for mounting parts at the position determined by design based on the set reference point, and the alignment consists of two right-angled sides. It has a plate body having a side, and has a dent hole that matches the position of the screw hole when the alignment side of the plate body is overlapped with the corner portion having the reference point. It is a thing.

It is a front view which shows the car door when the car is seen from the landing side. It is a front view which shows the car door before the forced disengagement switch is attached. It is a top view which shows the marking plate used for marking the position of the screw hole for fixing a forced separation switch on a movable side. It is a top view which shows the marking plate used for marking the position of the screw hole for fixing a forced deviation switch on a fixed side. It is a front view of the car door which shows the setting position of the marking plate.

Hereinafter, embodiments of the marking plate for elevator modification work and the marking method according to the present invention will be described with reference to the accompanying drawings.
In this embodiment, as an application of the marking plate, in the renewal work of the elevator, in order to strengthen the measures to prevent the door from opening, the position of the screw hole for fixing the forced divergence switch is assumed to be injured on the car door. It is a form.

Here, FIG. 1 is a diagram showing car doors 11A and 11B when the car is viewed from the landing side.
The car doors 11A and 11B are two single doors, and the car door 11A is the door on the door stop side. In FIG. 1, reference number 10 indicates a door machine and 12 indicates a door machine base. A door rail 18 is horizontally provided on the door machine base 12, and the car doors 11A and 11B are suspended on the door rail 18 so as to be opened and closed via rollers 16 and 17 of the door hangers 15A and 15B. A belt 13 driven by the door driving device 14 is stretched over the upper part of the door machine base 12, and the power for opening and closing the door is transmitted from the belt 13 to the cages 11A and 11B.

The car door 11A on the door stop side is provided with the following engaging device in order to link the opening and closing of the landing door with the car doors 11A and 11B.
The engagement device comprises a fixed engagement vane 20a and a movable engagement vane 20b. Both the fixed engaging vane 20a and the movable engaging vane 20b are long members having an L-shaped cross section. The fixed engagement vane 20a is fixed to the car door 11A in a vertical position, whereas the movable engagement vane 20b is connected to the fixed engagement vane 20a via a link 21 so as to form a parallel link mechanism. Has been done.

The landing door (not shown) has a movable engagement roller and a fixed engagement roller that engage between the fixed engagement vane 20a and the movable engagement vane 20b as an engaged device, and further locks and unlocks the landing side door. Equipped with an interlock lever for the lock. When the car doors 11A and 11B are opened, the movable engaging vanes 20b approach the fixed engaging vanes 20a, the distance between them is narrowed, and the movable engaging rollers and the fixed engaging rollers are sandwiched between them. When the engagement between the fixed engagement vane 20a and the movable engagement vane 20b is established in this way, the door opening power is transmitted to the landing door side.

Next, in FIG. 1, reference number 22 indicates a forced divergence switch on the movable side, and 24 indicates a forced divergence switch on the fixed side.
The forced dissociation switch 24 on the fixed side is fixed to a predetermined position on the door machine base 12 via the bracket 23 with a screw, and the forced dissociation switch 22 on the movable side is fixed to the predetermined position on the door hanger 15A via the bracket 25. It is fixed in position using screws.
The forced dissociation switch 22 on the movable side has a terminal fitted to the forced dissociation switch 24 on the fixed side at the tip of the lever 22a. When the car doors 11A and 11B are closed, the forced divergence switch 22 on the movable side and the forced divergence switch 24 on the fixed side are connected, and the closed state is detected by a short circuit of the circuit. On the other hand, if the car doors 11A and 11B are open, the connection between the forced divergence switch 22 on the movable side and the forced divergence switch 24 on the fixed side cannot be established, so the open state is detected and the car runs. It is designed not to be done.

Next, FIG. 2 is a diagram showing the car doors 11A and 11B in the state before the forced dissociation switch is attached.
Screw holes 26 and 27 are drilled at predetermined positions at the end of the door machine base 12 on the door stop side. The screw holes 26 and 27 are screw holes into which screws for fixing the bracket 23 for attaching the forced dissociation switch 24 on the fixed side are screwed. The door hanger 15A on the door stop side is machined with screw holes 28 and 29 for fixing the bracket 25 of the forced dissociation switch 22 on the movable side.

Here, the positions of the screw holes 26 and 27 for fixing the forced deviation switch 24 on the fixed side are predetermined based on the design drawing with reference to the reference point 40. In the case of this embodiment, the reference point 40 is set at the vertices of the two right-angled sides at the corner portion of the door machine base 12. Of the two sides, one extends vertically and the other extends vertically. The positions of the screw holes 26 and 27 are specified by the horizontal and vertical distances from the reference point 40, respectively.

Similarly, the positions of the screw holes 28 and 29 for fixing the forced dissociation switch 22 on the movable side are determined based on the design drawing with reference to another reference point 50. In the case of this embodiment, the reference point 50 is set at the vertices of the two right-angled sides at the corner portion of the door hanger 15A. The positions of the screw holes 28 and 29 are specified by the horizontal and vertical distances from the reference point 50, respectively.

Next, FIG. 3 shows a marking plate used for marking the positions of the screw holes 28 and 29 for fixing the forced dissociation switch 22 on the movable side. Marking holes 31 and 32 are formed at predetermined positions on the marking plate 30. In the case of this injured plate 30, two right-angled sides 41 and 42 are used as alignment sides, and the two sides 41 and 42 that form a right angle are aligned with the two sides that form a right angle at the corner of the reference point 50 shown in FIG. Occasionally, the positions of the marking holes 31 and 32 match the positions of the screw holes 28 and 29. The marking plate 30 is appropriately formed with cutouts 43 and 44 in order to avoid interference with bolts and door parts.

FIG. 4 shows a marking plate used for marking the positions of the screw holes 26 and 27 for fixing the forced dissociation switch 24 on the fixing side. Marking holes 36 and 37 are formed at predetermined positions on the marking plate 34. In the case of this injured plate 34, the two right-angled sides 51 and 52 are used as the alignment sides, and the alignment sides 51 and 52 are aligned with the two right-angled corners of the reference point 40 shown in FIG. Occasionally, the positions of the marking holes 36 and 37 match the positions of the screw holes 26 and 27. Note that 35 is not a screw hole but a scribe hole for marking the position of the hole through which the wiring is passed. Also in this marking plate 34, a notch 45 is formed in order to avoid interference with bolts and the like.
The marking plate for elevator remodeling work according to the present embodiment is configured as described above, and the worker rides on the car and performs the marking work using the marking plates 30 and 34 as shown below. be able to.

FIG. 5 is a diagram showing the setting positions of the marking plates 30 and 34.
The marking plate 34 is positioned by aligning its corner with the reference point 40 at the corner of the door machine base 12 and aligning the alignment sides 51 and 52 with the two right-angled sides of the corner while pressing it by hand. .. At this time, if marking is made from the marking holes 36 and 37 using a writing tool such as a pencil or a pen, the exact positions of the screw holes 26 and 27 can be marked.

Similarly, for the marking plate 30, align the corner with the reference point 50 at the corner of the door hanger 15A, and align the alignment sides 41 and 42 with the two right-angled sides of the corner while pressing them by hand. Position it. At this time, if marking is made from the marking holes 31 and 32 using a writing tool such as a pencil or a pen, the exact positions of the screw holes 28 and 29 can be marked.

The door stop of the car door 11A is sandwiched between the landing door and the landing wall, and the work space is very narrow, workability is very poor, and there are obstacles such as bolts, screw holes 26, 27, Accurate measurement is difficult in the dimensional measurement performed to determine the positions of 28 and 29. On the other hand, in the present embodiment, the positions of the screw holes 26, 27, 28, and 29 can be accurately marked by using the marking plates 30 and 34 without measuring the positions. As a result, the scribing work becomes much more efficient, and after making a hole with a dimensional error and installing the forced divergence switch, it was found that the forced divergence switch operated normally, and the dimensions were again measured. It is possible to reliably avoid a situation in which the measurement is forced to be redone.

In the above embodiment, the forced divergence switch has been described as an example of the parts to be attached, but the present invention is not limited to this, and can be applied to mark the screw hole position for attaching other types of switches. Is.
