Abstract

PURPOSE:To perform measuring work safely and easily by installing an engager which engages a vise part with a pull part of a squeeze dynamometer together, while installing a lever, operating a contact maker, in a grasping part. CONSTITUTION:With operation of a lever 29, each of paired contact makers 25 comes into contact with both sides of a moving handrail 2, and a grasping part 3 with these contact makers 25 grasps the moving handrail 2. A frame 4 being fitted with this grasping part 3 at the tip is provided with a squeeze dynamometer 5 in the rear, so that if the moving handrail 2 travels, the frame 4 and the squeeze dynamometer 5 both are pulled via the grasping part 3. On the other hand, a vise part 7, where the frame 4 is displaceably installed, is set up so as to bestride the moving handrail 2, holding a handrail 1 in between under pressure, while the vise part 7 and a pull part 6 of the squeeze dynamome ter 5 are engaged with each other via claws 15a (engagers). In brief, the dyna mometer 5 is pulled by the moving handrail 2, while the pull part 6 is held by the handrail 1 via the vise part 7, and a measurer reads graduations of the squeeze dynamometer 5 as operating the lever 29.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a moving handrail running force measuring device for an escalator.

[Conventional technology]

Conventionally, as a moving handrail running force measuring device for measuring the running force of a moving handrail, for example, as shown in Japanese Patent Application Laid-Open No. 58-55831 and Japanese Utility Model Application No. 61-119576,
A device has been proposed that includes a grasping section for grasping a moving handrail, a spring scale towed by the grasping section, and a pull section provided on the spring scale. In this proposed method, when the spring scale is pulled by the movable handrail via the grasping part, the measurer pulls the handle part of the spring scale in the opposite direction to the running direction of the movable handrail. It is designed to read the scale.

In addition, as shown in Japanese Utility Model Application No. 61-163284, there is also a grasping part for grasping the moving handrail, a scale attached to the grasping part via a magnetic coupling part, and a vise for pinching the handrail by straddling the moving handrail. It has also been proposed to have a section.

In this proposal, if excessive force is applied from the moving handrail, the (R-stone joint) separates.

In addition, with a gripping part for gripping this type of moving handrail, the surface of the moving handrail will not be damaged, and the sliding resistance between the inner surface of the moving handrail and the surface of the guide part of the handrail will not increase due to local gripping. We are starting to take these things into consideration.

[Problem to be solved by the invention]

By the way, among the above-mentioned conventional techniques, the former one in which the spring scale is pulled manually has the problem that not only does the measurer have to be strong, but he also has to perform the troublesome work of pulling the spring scale and reading the scale of the spring scale at the same time. There is. On the other hand, in the latter case, which is equipped with a grasping part that has a magnetic coupling part and a vise part that clamps the handrail, the magnetic coupling part may function separately when measuring the running force of the moving handrail. There is a concern that the scale pulled by the handrail may come off and hit the person taking the measurement, and there is also the problem of increased production costs.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to eliminate the need for manually holding the scale or providing a magnetic coupling part, and to
To provide a moving handrail running force measuring device capable of measuring running force without damaging the surface of the moving handrail or excessively increasing the sliding resistance of the moving handrail.

[Means for Solving the Problems] In order to achieve this object, the present invention includes a vise part that is arranged to straddle a movable handrail and that pinches a parapet that guides the movable handrail, and a vise part that has the above-mentioned a frame mounted movably in the traveling direction of the moving handrail; a grasping section having a pair of abutting elements attached to the tip of the frame and abutting on both sides of the moving handrail; and installed at the rear of the frame. In the mobile handrail running force measuring device equipped with a grip force meter scale, an engaging body is provided for engaging the vice part and a handle part of the grip force meter scale, and the grip part is actuated by the abutting element. It has a configuration with a lever that allows you to do so.

[Effect]

Since the present invention is configured as described above, by operating the lever, the pair of abutting elements come into contact with both sides of the movable handrail, and the grasping section having these abutting elements grasps the movable handrail. The frame to which this grasping part is attached at the tip is equipped with a grip force meter and scale at the rear thereof, and when the moving handrail runs, the frame and the grip force meter are pulled through the grasping part that grasps the moving handrail. On the other hand, the vise part on which the frame is displaceably mounted is arranged so as to straddle the movable handrail, and presses the column T, and engages the vise part and the pull part of the grip strength meter via the engaging part. match.

In other words, the grip force meter scale is pulled by a moving handrail, the pull part of the repulsion needle rod is held on the railing via a vise part, and the measurer reads the scale of the grip force meter scale while operating the lever. It has become. This eliminates the need to manually hold the scale or provide a magnetic coupling part, and without damaging the surface of the moving handrail or excessively increasing the sliding resistance of the moving handrail. Running force can be measured.
