Abstract

PURPOSE:To continuously detach a moving handrail by means of a small force exerted by a worker by providing a base with a guiding portion, a receiving portion and a receiving roller, the base being engaged with a guide in such a manner that it can travel along the guide 7. CONSTITUTION:A guiding piece 2 is first inserted between a moving handrail 8 having one part detached and a guide 7, and a base 1 is engaged with the guide 7 in such a manner that it can travel along the guido 7. Under these conditions, the base 1 is forced to travel along the guide 7. Thereby both side portions of the moving hand rail 8 are enlarged by both side portions 2B of the guiding piece 2 having its guiding portion 2A inserted, and the moving handrail 8 is separated from the guide 7 by a receiving portion 3 provided to the base 1. Next, both side portions enlarged of the moving handrail 8 are restored to their initial form at near the outer periphery of a receiving roller A provided to the base 1 and then the moving handrail 8 is detached from the guide 7. Thus, the moving handrail 8 is efficiently detached from the guide 7.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a moving handrail removal device for a passenger conveyor.

[Prior Art] Generally, a passenger conveyor includes an endlessly connected step that runs between two entrances and exits, a guide installed upright on the side of the step, and a passenger conveyor that is guided by the guide and runs in the same direction as the step. It consists of a moving handrail.

Conventionally, when removing the moving handrail of a passenger conveyor, as described in Japanese Patent Publication No. 58-30236, the handrail has a curved part fixed to the tip of the arm and a fulcrum part provided near this curved part. The worker who was using the moving handrail removal device for the passenger conveyor first screwed the curved part into the side edge of the moving handrail, operated the arm using the fulcrum part as a fulcrum, and
By this lever principle, the side edge of the moving handrail was removed from the guide.

[Problems to be Solved by the Invention] Since the conventional passenger conveyor moving handrail removal device is configured as described above, in order to remove the entire moving handrail, the above-mentioned operation must be performed while changing the screwing position of the curved part of the device. must be repeated, and this operation cannot be performed continuously and is therefore inefficient.

An object of the present invention is to provide a moving handrail removal device for a passenger conveyor that can efficiently remove a moving handrail.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a base that can run along a guide, and a leading part that is fixed to the tip of the base and inserted between the guide and the moving handrail. A moving handrail removing device for a passenger conveyor is constructed of a receiving part located behind the leading part to detach the moving handrail from the guide, and a receiving roller that rolls on the inner surface of the moving handrail after detachment. shall be.

[Operation] Since the moving handrail removal device for a passenger conveyor according to the present invention is constructed as described above, the leading piece is first inserted between the partially removed moving handrail and the guide, and the base is engaged so that the base can run along the guide. If the base is moved along the guide in this state, the moving handrail will be separated from the guide as it moves, and the moving handrail will now run on the outer periphery of the receiving roller. The moving handrail can be continuously and efficiently removed from the guide with a small force.

[Example code] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the movable handrail removal device.

A pair of traveling guides 5 are provided at the bottom of the base 1, and the vehicle can travel along the guides.

A leading piece 2 is fixed to the tip of this base 1,
The leading part 2A is formed into a tapered shape and is inserted between the guide and the moving handrail, and the chamfered side parts 2B weaken the engagement force of the moving handrail with the guide and help the receiving part 3 to remove it. This receiving part 3 is made up of two chamfered receiving pieces, and is located behind the leading piece 2 to move the moving handrail away from the guide. Further, at the rear of the receiving portion 3, a receiving roller 4 is provided between a pair of handles 6. This receiving roller 4 is formed so that its outer circumferential surface is higher than the receiving part 3, and is rolled by the moving handrail after detachment, so that the moving handrail can run smoothly. This allows the operator to work with less force.

This moving handrail removal work will be explained with reference to FIGS. 2 and 3.

First, the operator uses a separate tool to remove a part of the handrail 8 near the boundary between the inclined part and the horizontal part on the lower entrance/exit side. From there, the guide portion 2A of the moving handrail removal unit is inserted between the guide 7 and the moving handrail 8, and the traveling guide 5 of the base 1 is engaged with the guide 7. The operator holds the handle 6 and moves it toward the upper entrance as shown by the arrow in the figure. As a result, both sides 2B of the leading piece 2 into which the leading part 2A has been inserted spread out both sides of the moving handrail 8, causing the receiving part 3 to separate from the left side. Then, as shown in FIG. 3, which is viewed from the 1-1 cross section in FIG. .

In this way, first, a part of the moving handrail 8 is removed, and the moving handrail removing device is inserted and run at this location, and the moving handrail 8 runs on the rolling receiving rollers, so that it can be removed with a small force by one worker. , the movable handrail 8 can be removed continuously and efficiently.

In this embodiment, the leading piece 2 has a leading part 2A and both side parts 2.
B is formed, and the receiving portion 3 is formed of two receiving pieces, but each may be formed as a single member or may be constructed separately.

[Effects of the Invention] As explained above, the present invention provides a leading portion, a receiving portion, and a receiving roller on a base that is movably engaged with a guide. Since it is only necessary to move the moving handrail in the longitudinal direction, the moving handrail can be continuously removed with a small amount of force by the worker, and the work can be carried out efficiently.
