JPH0769583A - Gantry type steel structure with crane beam - Google Patents

Abstract

PURPOSE:To prevent a human disaster and a product damage from occurring by providing the column base of a steel frame with a beam for mounting a heavy crane in such a way as capable of planar turn about a tie-in section with the column base. CONSTITUTION:The column base 4 of a gantry type steel structure is provided with a wall crane 1. The vertical member 6 of the crane 1 runs inside a through- tube 8. This tube 8 is connected to the column base 4 via fastening members 9a and 9a and capable of turn about the member 6. Also, a beam 5 is fitted with a chain block support 12 having a roller 11, and a cargo is lifted with a chain block 2. When a travel type complex cargo handling facility with a cargo lifted is made to run and the cargo has a possibility of colliding with material, equipment or the like on the ground, the chain of the chain block 2 is pulled toward the column base 4. As a result, the roller 11 rotates and nears the column base 4. Also, the beam 5 is turned by further pulling the chain, and the collision can be thereby avoided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to installation of a static frequency converter, and relates to a cargo handling facility for carrying in and installing a main engine and auxiliary equipment.

[0002]

2. Description of the Related Art Conventionally, a gantry crane has been used as a main machine for a loading / installing cargo handling device in the installation of a static frequency converter of this type. For auxiliary equipment, because the installation location is small, it was carried in and installed manually using wires and chain blocks, but it had the drawback of high potential for personal injury and product damage. .

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned drawbacks of the conventional method and to install and install the main body and auxiliary equipment with a single jig in the installation of the static frequency converter. The purpose is to provide "mobile compound cargo handling equipment equipped with a wall crane" that enables construction.

[0004]

SUMMARY OF THE INVENTION The present invention is intended for carrying in and installing a stationary frequency converter main body by using auxiliary equipment for a stationary frequency converter that has been manually carried in and installed by using a wire and a chain block. The gantry crane's legs or multiple legs are integrated into a wall crane that can move the mounting part up and down and can rotate.

[0005]

[Practical example] The static frequency converter is installed and installed separately in the main body, the laminated thyristor valve, and the auxiliary equipment. Although a mobile gantry crane is used for the main body, the loading and installation of auxiliary equipment such as insulators that are placed in a narrow space is a very difficult task due to many factors that can cause personal injury and physical damage. The present invention makes it possible to install a gantry crane, move the gantry crane over an obstacle on the carry-in path, carry it in to the installation position, and perform installation.

A description will be given below with reference to FIG. The wall crane 1 is attached to a part of the column base 4 of the movable composite cargo handling facility 3, that is, the gantry type steel structure. The structure of the wall crane is shown in FIG. That is, the wall crane 1 is formed of a truss structure, that is, a beam 5, a vertical member 6, and a diagonal member 7, the vertical member 6 penetrates into a through pipe 8, and the through pipe 8 is attached to the column base 4 by attachment members 9a and 9b. Has been. A thrust bearing (not shown) is built in the thrust bearing box 10 above the vertical member 6.
As will be described later, the structure is such that the load hung on the chain block 2 can be received by the thrust bearing and can be swung about the vertical member 6. The beam 5 has a chain block supporter 12 with rollers 11, the chain block 2 is hung below the supporter, and the chain block 2
The load to be lifted is hung at the bottom of the. When the movable composite cargo handling equipment 3 is run with the load suspended, if the load may collide with other equipment installed on the ground, pull the chain of the chain block to the column base side, The beam 11 can be swung by avoiding collision by rotating the beam 11 toward the column base and pulling the chain if necessary. In addition, although the diagonal member 7 is shown as a steel material in FIG. 2, this is used as a wire rope, and an undulating device (not shown) is provided at a part of the column base 4 and the beam 5 is provided.
The beam 5 can be undulated in the vertical direction by combining the vertical member 6 with the vertical structure. In this case, the chain block 2 is fixedly attached to a part of the beam 5.

[0007]

According to the present invention, the static frequency converter can be installed with one dedicated jig, the jig installation for auxiliary equipment is not required, the construction period can be shortened, work at high places is eliminated, and excellent safety is achieved. It has effects such as being obtained.
