Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jig for mounting a wheel supporting bracket of a hoist crane, and a hoist crane manufacturing method using the jig.

The present invention relates to a jig for mounting a wheel support bracket of a hoist crane and a method of manufacturing the hoist crane using the jig, wherein the support bracket of the beam, which is a means for moving the hoist crane left and right, is mounted parallel to the rail, The present invention relates to a jig for mounting a wheel supporting bracket of a hoist crane and a method for manufacturing a hoist crane using the jig.

In general, ceiling cranes are most commonly used in cranes, and can be used for ceiling parts such as factories, warehouses, etc., so that heavy objects can be easily transported.

A rail is laid along the walls facing each other, and a beam running at right angles to the rails. This beam is equipped with a trolley with hoisting and traversing devices to lower the hooks from the trolley to lift the weight.

By moderating the movement of the beam and the lateral movement over the beam, the cargo can be carried anywhere in the building. The small thing is that a man drives from the ground with a passive chain, usually a man in a cab hanging on a beam, looking down at the hanging cargo.

The most commonly used beam is 6 ~ 26m in length and 3 ~ 200t in lifting load. It is called a ceiling crane with a hoist that the hoist is attached instead of the ordinary type trolley.

Here, the overhead crane and the hoist crane are collectively referred to as a hoist crane in the following description.

1 is a view showing a conventional beam.

Referring to FIG. 1, the beam 10 is mounted centrally to move along a rail installed in a factory or a warehouse.

The number of the wheels 20 can be variously mounted according to the size of the beam 10, and in particular, it is important to maintain balance of the wheels 20. The wheels 20 are coupled to the shaft 30 on both sides of the beam 10 and then coupled to the shaft 30 to move along the rails.

Since the support bracket 40 is directly welded to both sides of the worker, the support bracket 40 is not installed on both sides of the support bracket 40 horizontally and precisely so that the axis of the wheel 20, which is coupled to the support bracket 40, It is difficult to move the cargo in the proper place and damage of the beam 10 occurs.

FIG. 2 is a view for explaining a method of welding a support bracket 40 to a beam 10 of FIG. 1 according to an embodiment of the present invention. As shown in FIG. 2, And a shaft 60 is coupled to the mounting part to mount the support bracket 40. [ However, when considering that the support bracket 40 is welded by placing the beam on the support plate 50 of the jig, the support plate must be located on a flat surface, and jig movement may occur due to the load of the beam, There is a problem that the beam can not be accurately welded to the beam, and the load of the jig itself is too heavy, so that it is difficult to finally separate the beam from the beam.

KR 10-0957533 B1

The base part 100 is for the crane beam 10 to be seated.

The upper part of the base part 100 is formed in the shape of a flat plate 110 to receive the crane beam 10, and the lower part forms the slide body 120. Here, the flat plate 110 should have a high flatness and a width of the crane beam 10, so that the crane beam 10 can be sufficiently seated. Then, the slide body 120 is fitted to the following receiving part 500, so that the base part 100 can slide.

The mounting part 200 can be located inside the crane beam 10.

The mounting part 200 is installed on the base part 100 in the form of a rectangular support. More specifically, the mounting portion 200 includes both side walls 220 formed with insertion holes 230 and a reinforcing wall portion 240 reinforcing the strength by connecting both ends of the side walls 220.

The two side wall portions 220 are formed to be spaced apart from each other by a predetermined distance so as to be closely attached to the inside of the crane beam 10 and have insertion holes 230 passing through corresponding positions, Can be inserted and installed through the beam. The insertion hole 230 is formed at a position where the through hole 11 of the crane beam 10 communicates with the through hole 11 in a straight line.

The mounting portion 300 is configured to be coupled to the mounting portion 200 and the crane beam 10 to mount the supporting bracket 40 thereon.

One end of the mounting portion 300 is larger than the diameter of the insertion hole 230 and is insertable and detachable from the outer side to the outer side of the mounting portion 200 through the insertion hole 230.
