Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a moving force measuring device for a moving handrail of an elevator, and in particular, a moving force measuring device suitable for safely and easily measuring the running force of a moving handrail. This invention relates to a handrail running force measuring device.

[Prior Art] Conventional 1, for example, as shown in Japanese Unexamined Patent Publication No. 58-55831, a gripping body having a pair of grippers grips a movable handrail, and a spring scale indexed by this gripping body. A running force measuring device for a movable handrail has been proposed, which has a puller provided on this spring scale. In the conventional moving handrail running force measuring device configured in this way, the sliding motor that moves the moving handrail is stopped to stop the moving handrail, and the moving handrail is clamped by the gripper. As a result, the movable handrail is gripped by the gripper. Next, the drive motor is activated to move the handrail, and the worker pulls the pull of the spring scale in the opposite direction to the direction in which the handrail moves, and when the handrail is stopped, the scale of the spring scale is adjusted. It is designed to read.

Further, as shown in Japanese Utility Model Application Publication No. 61-163284, a gripping body having a pair of grippers and gripping a moving handrail, and a spring scale attached to this gripping body via a magnetic coupling part, It has been proposed that a vice be provided to straddle the movable handrail and press the parapet, and that the magnetic coupling part separates when excessive running force is applied to the movable handrail.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional moving handrail running force measurement device, the work of attaching and detaching the gripping body to the moving handrail is very troublesome in the former device. When measuring the running force of a handrail, two people are required: one to handle the running force measuring device and the other to operate the drive motor.
The problem was that the work costs were high. On the other hand, in the case of the latter type, which is equipped with a magnetic coupling part, if an excessive running force is applied to the moving handrail, the magnetic coupling part automatically separates, so the spring scale comes off from the grip that is indexed to the moving handrail and the work is carried out. There was a risk that the worker would be injured.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to provide a mobile handrail that allows the grip body to be easily attached and detached from the handrail and to safely measure the running force of the handrail. An object of the present invention is to provide a handrail running force measuring device.

The device includes a gripping body and a measuring body that is relatively movably attached to the gripping body and measures the tensile force applied through the puller, and measures the running force of the moving handrail via the gripping body. In the running force measuring device for a moving handrail, an actuating means is provided on the gripping body and operates the gripping element as the measuring object moves relative to the measuring object, and a locking means capable of locking the measuring object to the gripping body is provided. This is a configuration that includes means.

[Operation] Since the present invention is constructed as described above, when measuring the running force of the moving handrail, first, the measuring object is engaged with the grasping body by the locking means while the graspers of the grasping body are separated from each other. Next, in this state, the gripping bodies are attached to the movable handrail so that the grippers are located on both sides of the movable handrail. Next, when the above-mentioned measurement object is released from the gripping body and the gripping bodies are respectively engaged with the moving handrail, these grippers are driven by the friction between them and the moving handrail. Ru. At this time, if the handle of the measuring object is held, the measuring object moves relative to the gripping body. Along with this, the actuating means operates the grippers, so that one gripper comes into contact with both sides of the moving handrail, that is, the gripping body grips the above-mentioned moving handrail while indexing the object to be measured. do. Next, the puller is pulled against the running force of the movable handrail to stop the movable handrail.

The tensile force applied through the puller is measured by a measuring body. After measuring the running force of the moving handrail as described above, the grippers of the gripping body are separated from each other, and the measurement object is attached to the gripping body by the locking means while each of the grippers is separated from the side of the moving handrail. is locked, and in this state, the grip body is released from the movable handrail. This allows the grip body to be easily attached to and detached from the movable handrail.

In addition, since there is no magnetic coupling part that separably connects the measuring object to one gripper, the measuring object will not come off from the gripper even if an excessive running force is applied to the moving handrail, and the moving handrail can be safely attached. The running force of the vehicle can be measured.
