Abstract

PURPOSE:To check a motor start-up at time of a test run by installing a power transmission body detecting arm in the inner part of a main frame, operating a switch with power transmission body detecting operation at time of the test run of this arm, and making it so as to regulate the motor start-up. CONSTITUTION:When a test run takes place, a chain 18 is rolled on a sprocket 63 of a reduction gear 6 and another sprocket 17 available at the test run, while a shoe 20 of a power transmission body detecting arm 19 is made contact with the chain 18, operating a switch 21 by an inclined arm 19. Next, when a test run handle is rotated by hand, power is transmitted to an input shaft of the reduction gear 6 via a pulley 15, the sprocket 17, the chain 18 and the sprocket 63, and an output shaft 64 is rotated. Since the chain 18 is removed in all cases other than the test run time, the arm 19 is hung down, coming to a nonoperating state with the switch 21.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the structure of a test run device for a passenger conveyor, which is equipped with a driving machine in the longitudinally intermediate portion of a main frame.

(Prior art) A person conveyor such as an escalator is a device that transports people and cargo by circulating the steps based on the drive of a driving machine, but during installation and maintenance, the steps are manually moved in circulation at a low speed for trial operation. There is a need to.

However, in the case of a passenger conveyor in which the step chain of the steps is composed of a toothed link, and the drive machine that meshes with the toothed link is installed in the longitudinally intermediate part (slanted part) of the main frame,
Since the stairs, which are the only place to work, move during the test run, it was inevitable that the test run would be complicated and safety would be lowered.

Therefore, Japanese Patent Publications No. 61-41835, No. 61-41836, Japanese Utility Model Publication No. 59-50965, and No. 59-68778 have proposed test run devices capable of correcting the above-mentioned disadvantages.

[Problems to be Solved by the Invention] Since the conventional trial run device for a passenger conveyor was configured as shown below, it was difficult to accidentally turn on the power to the passenger conveyor during the trial run and turn on the first motor (4). ) Wake up! [I] If this happens, problems such as damage to equipment and injury to workers arise.

The present invention has been made in view of the above, and its purpose is to provide a test run device for a passenger conveyor that can prevent the motor from starting during a test run σ).

[First stage for solving the problem] In order to achieve the above-mentioned object, the present invention provides a speed reducer which is disposed in the longitudinally intermediate portion of the main frame of the passenger conveyor and operates based on the drive of a motor to circulate and move the steps. a handle provided at the end of the main frame that rotates based on human operation during a trial run of the conveyor; a shaft located adjacent to the reducer that rotates as the handle rotates; a rotating body of this shaft; An endless power transmission body is installed between the rotating body of the input shaft of the reducer and the main frame during the test run of the passenger conveyor, and the reducer is operated as the handle rotates during the test run. , a rotatable arm that detects the power transmission body is pivoted, and a switch is provided that operates based on the detection of the power transmission body of this arm and restricts the activation of the motor during a trial run. It is characterized by

[Effect]

According to the present invention, a rotary self-sensing arm for detecting a power transmission body is pivotally supported inside the main frame of the passenger conveyor, and the arm operates based on the detection of the power transmission body. By disposing a switch 1 that regulates starting during a test run, it is possible to omit a switch 1 and a switch device that prevents the starting of the C-driving motor during a test run.
