Abstract

(57) [Summary] [Purpose] The maximum hoisting height can be obtained even in places where the deck height or ceiling height is limited, such as in the engine room of ships, in buildings such as machining or machine assembly plants. Trolley traveling device. [Structure] A steel roller 2 rolling on the upper surface of a lower flange of a trolley beam 1, a steel roller spindle 3 for pivotally supporting the steel roller 2 from a side girder member 5, and a connection for connecting a lower part of the side girder member 5. Trolley traveling including a rod 6, a bottom plate 2, a suspension piece 9 fixed to the upper portion of the side girder member 5, and a rubber roller 4 rolling on the abdominal plate portion of the trolley beam 1 axially supported from the inside of the upper side girder member 5. apparatus.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a trolley truck that rolls a traveling beam fixed in a building such as an engine room of a ship, a machining factory or a machine assembly factory.

[0002]

[Prior art]

 Conventionally, in this type of trolley cart, it is known that a suspension piece is fixedly installed at the bottom of the cart.

[0003]

[Problems to be solved by the device]

 According to the conventional technology, since the hanging piece is fixed to the lower part of the trolley, the minimum hoisting required for assembling and disassembling the machine, etc., in the place where the ceiling is extremely low. There was a problem in that it was necessary to secure a large deck or ceiling height when the height could not be secured or when the equipment was installed.

The present invention has been made in view of the above problems of the conventional technology, and its object is to maximize the hoisting height even in a low place where the ceiling height is limited. The present invention is intended to provide a trolley traveling device that can obtain high quality.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a trolley traveling device according to the present invention is a steel roller that rolls on the upper surface of a lower flange of a trolley beam made of I-shaped steel or H-shaped steel. Spindle for steel roller supporting the shaft, connecting rod and bottom plate for connecting the lower part of the side girder, suspension piece fixed on the outer side of the upper part of the side girder, and trolley beam abdominal plate supporting from the inside of the upper part of the side girder It is composed of a rubber roller that rolls over the part, and it can be hung and held at the maximum hoisting height even in a low place where the ceiling height is limited.

[0006]

[Action]

 The suspension piece fixed to the upper end of the side girder material secures a large suspension allowance by approximately the depth of the trolley beam.

[0007]

【Example】

 Examples will be described with reference to the drawings. In FIG. 1, a suspension piece 9 having a small hole 10 is fixed to one side of the top of a side girder member 5 made of a flat steel plate, and a roller column 8 having a rubber roller 4 attached thereto is fixed to the opposite side of the suspension piece 9. To do.

A steel roller spindle 3 for mounting a steel roller 2 having a built-in cylindrical roller bearing is fixed from a substantially middle portion of the side girder plate in the vertical direction.

Two side girder plates 5 on which the rubber roller 4 and the steel roller 2 are mounted are made to face each other with respect to the trolley beam 1, and a plurality of connecting rods are provided slightly below the lower end surface of the trolley beam. The bottom plate 7 made of a thin steel plate is fixed to the lower end surface of the side girder plate 5 with a small screw 11.

[0010]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the hanging piece is fixed to the upper end portion of the side girder plate, the hanging allowance is increased by about the depth of the trolley beam, and the ceiling height can be reduced accordingly.

Since the two side girder members are respectively screwed in the lower part, the connecting rod is a nut, and the bottom plate is screwed with a small screw, disassembly, inspection, and repair work can be easily performed.

Claims (1)

[Scope of utility model registration request] 1. A steel roller which rolls on the upper surface of the lower flange of a trolley beam made of I-shaped steel or H-shaped steel, a steel roller spindle for axially supporting the steel roller from a side girder material, and a side girder material. It is composed of a connecting rod for connecting the lower part, a bottom plate, a suspension piece fixed outside the upper part of the side girder member, and a rubber roller for rolling the abdominal plate part of the trolley beam pivotally supported from the inside of the upper part of the side girder member. The trolley traveling device is characterized in that the maximum hoisting height can be obtained even in a low place where the height is restricted.
