JPH0441388A - Carraige for escalator installation work - Google Patents

Abstract

PURPOSE:To achieve a safe and effective work by providing a horizontal work floor in a work carraige, and providing a member storing fool under the horizontal work floor. CONSTITUTION:By providing a horizontal work floor 20 in a work carriage 13, a stable attitude can be secured in an escalator installation work, and an abnormal fatigue at an ankle part of a worker by inclination of the work floor can be prevented. Because the work carraige 13 has a horizontal surface, more of necessary members for the work can be mounted and carried compared to a case where the mounting surface is inclined, and possibilities of burden collapse, etc., can be reduced. A safe and effective work can thus be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a work trolley suitable for installation work of a handrail portion of an escalator.

[Conventional technology]

Conventionally, when installing an escalator's handrail, after completing the installation of the frame, kite rail, step chain, and other internal components of the frame, a board is laid on the many front roller shafts provided on the step chain. The parapet members were transported and installed while using the boards as scaffolding.

Furthermore, as described in Japanese Patent Application Laid-Open No. 62-211287, a work trolley with a working surface parallel to the intermediate inclined surface of the escalator is attached to the step chain, and the handrail member is transported and installed while being moved by a low-speed operation device. was working.

[Problem to be solved by the invention]

Conventional work scaffolds with plates spread over the front roller shafts and work carts described in JP-A No. 62-211287 have working platforms that are inclined parallel to the slope of the escalator, making it difficult to work for long periods of time. When this occurs, workers may experience abnormal ankle fatigue and complain of pain. In addition, because the floor of the work trolley is sloping, long railing assemblies that are placed on the work trolley for installation may dislodge due to the movement of the work trolley, and the number of parts that can be placed may be limited. There were a few problems.

The purpose of the present invention is to make it possible to work safely and with less fatigue even when working on a work trolley for a long time, to significantly increase the number of parapet parts to be placed on the work trolley, and to reduce the risk of load collapse. The purpose of the present invention is to provide a cart for escalator installation work that is highly efficient and safe.

[Means to solve the problem]

In order to achieve the above object, the present invention is characterized in that the work cart is provided with a horizontal work floor, and a material storage floor is provided below the horizontal work bed.

[Function] The escalator installation work trolley according to the present invention has a horizontal work floor, so it can ensure a stable posture during installation work, and prevents abnormal ankles of the worker due to the slope of the work floor. Fatigue can be prevented. Also,
Since the work trolley has a horizontal surface, it is possible to carry more parts than when the mounting surface is inclined, and there is less risk of the load falling off.
Able to perform work safely and efficiently.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the escalator during installation work. The frame 1 consists of an upper horizontal part 1a, a lower horizontal part 1b, and an intermediate inclined part 1c, with a drive sprocket 2 in the upper horizontal part la and an abrasive sprocket 3 in the lower horizontal part lb. are arranged respectively. These drive sprockets2. A step chain 8 having front wheel roller shafts 10 corresponding to the number of steps is wound between the idler sprockets 3, and the drive sprocket 2 is
It is connected to the main motor 4 via the drive chain 7, reducer 6, etc., and after the escalator is installed, the main motor 4 drives the drive sprocket 2, and further drives the step chain 8. It has become. In this way, the drive mechanism section of the escalator is configured. Further, the guide rail 9 extends along the longitudinal direction of the frame 1.
A work floor 20, a transport work floor 21, an operation panel 19, a winding device 14 for the signal line 15, and the like are mounted and fixed on the top. This operation panel 19 is connected via a signal line 15 to a control panel 18 of a low-speed operating device 17 temporarily installed on the upper horizontal portion 13 of the frame 1 . This low-speed operation device 17 is an inverter device that outputs variable frequency and variable voltage for driving the work trolley 13, and is connected to the drive mechanism of the escalator via a power cable 23 for driving. Furthermore, by controlling the brake 5 of this drive mechanism section with the control panel 8, the drive by the low speed operation device 17 can be stopped. Therefore, operation panel 1
9, the low speed driving device 17 is driven, the drive sprocket 2 is driven, and the step chain 8 is driven.
, the working trolley 13 can be moved along the guide rail 9 together with the front wheel roller shaft 10. The signal line 15 has one end supported by a signal line support 16 temporarily installed on the landing board 12 section attached to the upper horizontal section 12 of the frame 1, and the other end supported by a signal line support 16 provided on the work trolley 13. It is connected to the take-up device 14, rotates the take-up device 14 in accordance with the movement of the working trolley 13, and sends a signal! It is supported so that it can follow the work trolley 13 by expanding and contracting the work trolley 15.

Further, the work trolley 13 is equipped with an operation panel 19 and a winding device 14 for the signal line 15, and is composed of at least one work floor including a main work floor 20 and a work floor 21 for transporting parts and tools. , the work floor 20 and the transport work floor 21 are arranged horizontally so that work can be done in a stable posture.

FIG. 2 shows the signal line 1 mounted on the work trolley 13.
5 is a detailed view of the winding device 14 of No. 5. FIG.

The winding device 14 includes a drum 1 rotating by a fixed shaft 14C.
4a and a base 14b that is fixed or placed on the work floor 20 on the work trolley 13, and a fixed shaft 14c.
There are any number of power supply brushes 25a, 25b, 25c on the drum side, and any number of power supply slip rings 2 on the drum side.
6a, 26b.

26'c is arranged so as to be in a sliding state, and a fixed signal line 24 connected to the operation panel 19 on the work trolley 13 is connected to the power feeding brushes 25a, 25b, and 25c.
Slip rings 26a, 26b.

A signal line 15 that can be wound up and stored is connected to the 26c side, so that even if the drum 14a is rotated by winding up the signal line 15, power is supplied.

In this way, the work floor 21 of the work cart 13 is arranged horizontally.
Accordingly, the worker rides on the work trolley 13 in a stable posture, operates the operation panel 19, and moves the signal line 15 to the work position by letting out the winding device 14 and winding it up as necessary. I can do it.

Furthermore, the work trolley 13 can be mounted and transported with assembled parts in a flat state without worrying about falling or shifting, which improves the general work efficiency.

In addition, in the above-mentioned embodiment, a case was described in which a low-speed operation device 17 using an inverter device that outputs variable frequency and variable voltage was temporarily installed, but if the permanently installed motor 4 is capable of low-speed operation, the low-speed operation device can be used. 17 may be omitted.

〔Effect of the invention〕

As explained above, the present invention provides a horizontal work floor on the work trolley, so it is possible to ensure a stable posture during escalator installation work, and the worker's ankles are not affected by the slope of the work platform. Abnormal fatigue can be prevented. In addition, since the work trolley has a horizontal surface,
Compared to the case where the mounting surface is inclined, more members necessary for the work can be placed and transported, and there is less risk of the load falling apart, so the work can be performed safely and efficiently.
