Description

[Detailed description of the invention] [Industrial application field] This invention is mainly used for welding the base material for fixing steel roof shingles to the roof of a building. Concerning a traveling trolley.

[Prior art and its problems] Currently, when fixing a steel plate, which is a roof plate, to the frame of a building, a base material is welded along the haze, and the roof steel plate is fixed to this base material. By the way, when welding the base material, a long and narrow base material is placed on the beam or mist in advance, and the base material is moved while walking on the mist to weld. However, with this construction method, the work is performed half-heartedly on top of a high and unstable mist, or by sitting on top of the mist with both feet sandwiched between the mist, making the work inefficient, tiring, and quite dangerous. There was a drawback.

By the way, welding carts that move along steel structures have been developed (Japanese Patent Publication No. 11576/1982 and Japanese Utility Model Publication No. 139718/1983). In these welding carts, rolls roll on a steel structure, and both sides of the steel structure are sandwiched between rollers or the like to prevent the cart from tipping over.

These welding carts can move along the shaped steel, but since they are used for welding steel structures and are not meant for people to sit on, they have a sloping roof with the top surface horizontal. It has the disadvantages of not being able to hold it and work while sitting stably and comfortably.

This invention was developed to eliminate this drawback, and the important purpose of this invention is to provide a traveling trolley that moves along the steel frame of the roof of a building, which has high work efficiency, reduces fatigue, and can work safely. There is something to do.

[Means to solve conventional problems] A traveling trolley that moves along the steel frame of the building roof,
A base on which a person sits, a plurality of rolls rotatably supported on the underside of the base, and multiple sets of clamps extending downward on both sides of the rolls. It is equipped with a rod. The base consists of a main body and a tilting table, and the tilting table is attached to the main body so as to be tiltable left and right so that it can be adjusted horizontally according to the slope of the roof. Furthermore, the plurality of rolls are supported by the main body through bearings so that they are spaced apart from each other in the front and rear of the main body and their rotational axes are oriented laterally and parallel to each other. Each set of clamping rods is also spaced apart from each other at the front and rear of the main body, and each set of clamping rods is connected to the main body so that the distance between them can be freely adjusted. The roll is placed on the structural steel of the roof and travels, the tilting table is tilted to match the slope of the roof and adjusted horizontally, and the clamping rods clamp both sides of the structural steel and move along the structural steel. Run.

[How to use] The method of using a traveling trolley that moves along the steel frame of a building roof is to widen the width of the clamping rod and place it on top of the shaped steel, then narrow the clamping rod and lighten both sides of the shaped steel. That is, it is held in a slidable state to prevent it from falling. The tilting platform of the base is tilted to match the slope of the roof and adjusted horizontally on the sloped roof. In this state, the roll is run on the top of the section steel to move it along the section steel, and the machine is used while sitting on a horizontal tilting table.

[Preferred Embodiment] Hereinafter, an embodiment of this invention will be described based on the drawings.

The traveling cart shown in Figures 1 to 4 has a base 1
, a roll 2 and a clamping rod 3.

The base 1 is composed of a main body 1a and a tilting base 1b.
The main body 1a is made of steel materials assembled into a square shape, and the tilting table 1b is attached to the top of this main body 1a so as to be able to tilt freely.

The main body 1a has a shaft 4 fixed thereto that extends back and forth from the center, and a bearing sleeve 5 rotatably inserted through the shaft 4 is welded to the lower surface of the tilting table to connect the bearing sleeve 5 and the shaft 4. Through this, the tilting table 1b is tilted left and right.

In the tilting table 1b, side plates 6 on both sides are located outside the main body 1a, and a set screw 7 is screwed through the side plates 6, and the set screw 7 presses the side surface of the main body 1a to tilt the tilting table 1b. will be stopped.

In this way, if the base 1 has a tilting base 1b, the top surface of the base 1 can be adjusted horizontally by placing it on a haze whose top surface is normally tilted, so that the user can sit more stably on this. .

At the rear of the base 1, a platform 8 is provided on which a tight frame, which is an elongated base material, is placed. This platform 8 has a Y-shaped overall shape, and is fixed on both sides.

Two rolls 2 are disposed at the front and rear of the lower surface of the main body of the base 1 so that the base 1 can still run on the section steel 9.

The two rolls 2 are mounted on bearings 1 at both ends so that the rolls 2 are oriented horizontally to the base 1 and parallel to each other.
It is supported on the main body via 0.

Although the traveling carriage shown in FIG. 2 is equipped with two rolls 2, it can also be used with three or more rolls supported on the base.

The clamping rod 3 is attached to the front part of the base 1 so that the roll 2 can run on the shaped steel without falling over by sliding on both sides of the shaped steel 9. One set of clamping rods 3 is provided at each rear part, and each set of clamping rods 3 is extended downward and the spacing between them is adjustable so that sections of different widths can be clamped. The clamping rods in Figures 2 and 3 are
It has a cylindrical body 11 at the upper end, and this cylindrical body 11 is the main body 1a.
A sliding shaft 12 is fixed horizontally to the front and rear parts of the
A set screw 13 is screwed through the cylindrical body 11 in a movable manner, and the cylindrical body 11 is fixed to the sliding shaft 12 by screwing in the set screw 13.

The cylindrical body 11 at the upper part of the clamping rod is formed in a T-shape, and a rod 14 is inserted through the downwardly extending portion thereof, and this rod 14 is also fixed to a set screw 15 passing through the cylindrical body 11.

The rod 14 can be replaced by loosening the set screw 15.
According to this structure, the rod 14 can be replaced according to the height of the section steel, and can be conveniently used from high section steels to low section steels.

The cylindrical body 11 has female threaded holes into which setscrews 13 and 15 are screwed.

The traveling cart shown in FIGS. 2 and 4 is provided with clamping rods 3 at the front and rear of the base 1. Although not shown, these clamping rods are provided at the front, rear, and midway of the base. It is also possible to provide more than one location.

[Effects] The traveling trolley that moves along the steel frame of the building roof constructed as described above runs stably by sandwiching both sides of the section steel with the clamping rods, and can be moved easily with the rolls, so the tilting platform is By sitting on top and pushing the lower part of the shaped steel with your feet while moving, you can dramatically improve work efficiency compared to the conventional method of sitting directly on the mist or working half-heartedly. It has great effects, such as greatly reducing fatigue during work and making work at heights extremely safe.

Furthermore, in addition to this, the tilting platform of the traveling trolley of this invention can be adjusted horizontally according to the slope of the roof, so the tilting platform can be adjusted horizontally at all times, regardless of whether the roof has a steep slope or a roof with a gentle slope. This allows you to sit stably and comfortably and work safely and efficiently.
