Abstract

PURPOSE:To improve the arrival-floor accuracy of a temporary elevator without increasing an operation time by counting the moving quantity of a cage from a position point at which the door opening zone detecting means of an existing elevator is operated by a counting means, and carrying out the arrival-floor control of the temporary elevator at a position point at which the counted value reaches a predetermined set value. CONSTITUTION:As an existing door opening zone detecting means 500 is operated by the travel of a cage 8, a counting means starts operating to count the moving distance of the cage from the position point at which the door opening zone detecting means 500 is operated by means of the counting circuit of a temporary control board 6SA. When the counted value reached a set value which is predetermined in accordance with the difference between the existing door opening zone and the required zone of a temporary elevator, it is determined to be the position point of the temporary elevator and an arrival-floor command is sent out.

Description

[Detailed description of the invention] [Industrial Icheon field]

The present invention relates to a control device for a temporary elevator used temporarily when an existing elevator is renovated.

[Conventional technology]

In recent years, the adoption of advanced electronic technology in elevators has promoted higher performance control devices, and as a result, power savings, safety, ride comfort, etc. have been significantly improved. At the same time, ME elevators that match modern sensibilities have appeared in recent years. On the other hand, old buildings are also modern! ! Various modifications have been made to improve the image of the five parties. This allows the old existing J-REP to be replaced with a new elevator.
“There is an increasing demand for instant renovations. However, when renovating an old existing elevator to a new one, the entire elevator must be remodeled, and the old existing elevator must be removed before the new one is installed. Elevator installation work must be done.Of course, the fortune-telling elevator must be removed before a new elevator is installed.-4
There is a problem in that the elevator cannot be used during the installation construction period, and the challenge is how to shorten this construction period. As a means to solve this problem, as shown in Figure 3, for example,
There is a method disclosed in Japanese Patent No. 5079. Figure 3 is a vertical diagram of the hoistway. In the figure, 1 is a hoistway, 2 is a machine room provided above the hoist 1, 3 and 4 are a hoisting machine and a deflector wheel installed on a machine 85 provided in the machine room 2, and 6 is a control board that controls the hoisting 113, 8 is a cage, and 9 is a counterweight. ] 1 is a three-sided frame, 12 is a landing door that opens and closes the entrance, 13 is a door that guides the landing door 12, 80 is a car frame, 100 and 101 are guide rails for cars and counterweights 1, 1.02 , 103 is the looseness of the cage and counterweight!

Stops on floor 111. The conventional control method as described above is independent of the equipment in room 2 by installing a temporary elevator. 8 is 111-71 on the 1st floor
5117 is to be provided with free service. In addition, the control system for the temporary elevator was configured using the door open zone, which is a nearly constant operating position, regardless of the control method and speed of the existing elevator. There is no need to install a new position detection switch for evening use, and the temporary elevator can be operated in a shorter time. Therefore, the temporary elevator can be used until the equipment and car in the weaving room 2 of the new elevator are installed, so it is possible to significantly shorten the period of time when the only transportation within the building is by stairs. Naturally, if the installation and removal work of the temporary elevator is not carried out during hours such as nighttime when the elevator is not frequently used, remodeling can be done with little inconvenience to the users.

[Issues to be Solved by the Invention (i)] In the conventional temporary elevator control device as described above, it is desirable that the door opening zone is approximately constant. On the other hand, the door opening zone of existing elevators varies depending on the speed and control system, and the difference is from several tens of millimeters to a hundred millimeters. Further, for safety reasons, the door opening zone tends to become narrower over time, and the value of the door opening zone is not fixed. By the way, the operation method of the temporary elevator is AC single speed, and the landing is started by the door σi -J-shi signal of the existing elevator, so the landing accuracy of the car is greatly affected by the set value of the door opening. It was changing. In order to improve the precision of landing, it is necessary to install the existing door lJ[
．． It was necessary to set up a temporary elevator and reconfigure each floor for the beta, which took a lot of time. Therefore, there was a problem in that the construction period for remodeling the C1 elevator was further increased, and the inconvenience of the noise caused by building movement was further increased. This invention was made in order to solve the above-mentioned problems, and an object thereof is to provide a control device for a temporary elevator that can improve the landing accuracy of a temporary elevator without increasing the working time. Tozuro. [Means for Solving the Problems] A control device for a temporary elevator according to the present invention includes a pulse generating means that generates a bus/L bus that is proportional to the moving distance of a car, and a door of an existing construction L/B/I. Counting the pulses from the 1,000-stage pulse generation from the position point where the open position detection means operates,
The counter includes a counting means that issues a landing command when the counted value reaches the position of the temporary elevator.

[Effect]

In this invention, when the existing door open zone detection means is activated by the running of the car, the counting means starts its operation.
The door opening zone detection means counts the moving distance of the car from the operating taro position point, and the counted value is calculated from the existing door opening zone. f-
When a predetermined setting value is reached according to the difference between the required zone in the shank construction L and beta, a landing command is sent out using this as the position point of the temporary elevator. Therefore, in the present invention, there is no need to reset the existing door opening/fine for the temporary elevator, and the landing accuracy of the temporary elevator can be improved without increasing the working time accordingly.

Hereinafter, embodiments of this invention will be explained based on the drawings.
r+ Figures I and 2 show an embodiment of the temporary elevator control device according to the present invention, with Figure 1 being a block diagram of the entire temporary elevator, and Figure 2 being an internal block diagram of the temporary control panel. . First, in FIG. 1, the temporary main rope 7S is wound around the rope Ill 3 S a, which is directly connected to the temporary hoisting motor 303, and the existing car 8 and the existing counterweight 9 are attached to both hanging ends of the rope Ill 3 S a. connected. 500 is an existing elevator door open zone detection means, which includes an existing door open zone detector 501 attached to the car 8 and a door open zone detection @501.

It is configured. In FIG. 2, the same symbols as in FIG. 4 indicate the same parts. Further, 406S is a stop backup relay for safely stopping the temporary elevator even if the counting circuit 407S is out of order. It is connected to a DC power supply 400S. DC power supply 400
The counting circuit 407S connected to the stop preparation relay 31. 1 2 3 and the normally open contacts 50 123 of the door open zone detection relay 501S are connected in series, and the counting circuit 407S starts counting operation when the external circuit 408S is closed. In addition, an output relay 4098 that is energized when the count @407S counts a predetermined number of pulses is connected to the counting circuit 407.

Next, the operation of this embodiment constructed as described above will be explained. Incidentally, since the operation when the elevator is started is the same as in the conventional case, the explanation thereof will be omitted. Now, when the car 8 is about to reach the stop preparation point of the destination floor 110, a stop preparation relay (not shown) operates and its normally open contacts 3111S and 311.2S flash. When the temporary structure 8 further approaches the destination floor 110 and reaches the door open zone of the destination floor 110, the detection field 501 of the door open zone detection means 500
engages the cam 502 and the door open zone is detected.

This is theory J.

【Effect of the invention】

According to the present invention, the amount of movement of the car from the position point where the door open zone detection means of the existing L/Beta operates is counted by the counting T stage, and the counted value reaches a predetermined set value. Since the configuration 17 is such that the landing control of the temporary elevator is performed at the determined position point, the landing accuracy of the temporary elevator can be improved without increasing the working time.
