Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides that a double cargo carriage can be moved along a suspension beam at a distance from each other by means of spindles, and that the carriage has a rotating shaft on its axis. The present invention relates to a suspension beam that is suitable for all types of lifting equipment in which two loading hooks or loading rings are attached that can rotate.

In the case of a suspended beam of the type described above, the cargo carriage runs directly on the lower band of rails provided inside the main beam, or directly on the upper band.

In the case of the former type, an auxiliary frame is required because the main beam is installed internally relative to the lower belt, which creates additional stress on the main beam, and the load is applied eccentrically to the main beam. Therefore, the rails must be supported at short intervals by bent thin plates.

Additionally, the cargo carriage is difficult to assemble because it must be disassembled and transported to the suspension beams and assembled within the limited space between the main beams.

In the case of the latter type of configuration, the additional stress due to eccentric loading can certainly be prevented, but in the case of this structure (
To obtain uniform safety against wobbling (due to incorrect adjustment or, as in the case of liquids, due to changes in the center of gravity of the load), the height of the suspension beam must be increased. .

A further disadvantage is that the spindle remains exposed and must be protected by some means to prevent damage.

The present invention eliminates these drawbacks of conventional suspension beams and provides a suspension beam that is easy to assemble and handle.

The suspension beam of the present invention comprises a double T-beam and a double carriage attached thereto, wherein the beam is provided with grooves facing each other on the lateral centerline. has an opening upwardly at each end of the suspension beam; the double carriage has sliding portions on both sides and each runs on a separate spindle; each carriage rotates about the axis of the carriage; The loading hook or ring is rotatably connected, and the carriage is connected to the double-T from the opening.
- It is characterized in that it can be inserted into a beam so that the sliding portion runs in a groove and hangs thereon.

In such suspension beams, the running groove of the cargo carriage slide is located on the center line of the beam, so that no frame is required to prevent web curvature and additional stresses are avoided. Ru.

Also, since the groove or rail is attached to the center of the beam, there is no need for the rail to be supported at short intervals by bent thin plates.

In addition, at the tip of the main beam, the upper main beam is shorter than the lower main beam, and there are openings above both ends of the suspension beam, so it is possible to fit the cargo carriage from above when it is completed. It can be installed with.

Therefore, according to the present invention, it is possible to obtain a movable weighing beam that is light in weight and low in height, and is easy to disassemble and assemble, making maintenance of the cargo carriage very easy and easy to handle.

Furthermore, with the suspension beam of the present invention, since the spindles are located inside the suspension beam, there is no need to protect them from damage, and each cargo carriage moves independently with its own spindle. You can move around.

The spindles can be rotated separately, for example by band wheels, chain wheels or electric motors located at each end of the beam, allowing the cargo carriage to move independently.

In a preferred embodiment of the invention, two hanging fittings are provided for connecting the carriage shaft and the loading hook or loading ring, the hanging fittings having a stop working with the upper groove border and a slide. A slot is provided perpendicular to the pivot.

Generally, when the suspension beam is lowered and touches the ground, the loading ring is pushed upwards, that is, towards the spindle.
Although the spindle is easily damaged by loading hooks or rings, the aforementioned stop and slot should be provided in such a way that the distance between the stop and the upper boundary of the groove in the vertical direction is less than the distance between the slot and the pivot. Therefore, even if the loading hook or line is pushed up, the stopper will hit the upper boundary of the groove, and the spindle will not be affected by it, thus preventing damage to the spindle.

Therefore, the beam can be lowered without worrying about damaging the spindle.

Next, the present invention will be explained in more detail according to an example shown in the drawings.

The hanging beam in the drawings is a double T-beam, with a U-shaped groove 1 opening laterally opposite each other in the inner central part of each web of the main beam 2.
The lower side of the rail 3 serves as a rail 3 for moving the cargo carriage 5.

. The cargo carriage 5 has a sliding section 4 that slides upward on the rail 3.
A spindle bearing 1 for transmitting the action of a spindle 8 to the sliding part 4 is attached to the center of the sliding part 4, and the spindle 8 passes through this bearing 7.

Further, a hanging metal fitting 9 is attached to the pivot 14 of the sliding portion 4 so as to be rotatable around the carriage shaft 11, and the loading ring 6 is connected to the hanging metal fitting 9.

A stopper 10 is provided above the hanging fitting 9 so as to protrude outward (on the groove side), and the engagement position with the pivot 14 can be moved below the pivot 14 at the engagement portion of the hanging fitting 9 with the pivot h14. A slot 13 is provided.

The stopper 10 and the groove hole 13 are formed such that the distance between the stopper 10 and the upper boundary part 12 of the groove 1 in the vertical direction is smaller than the distance between the groove hole 13 and the pivot 14, so that the hanging beam Even if a force is applied from below to the top on the hanging fitting 9 when the
, the lifting member 9 can be swung upwards without hitting the pivot 14, and this avoidance behavior stops when the stop 10 hits the upper border 12 of the groove 1, thereby avoiding damage to the spindle. Kill by stopping.
