Description

[Detailed Description of the Invention] The present invention relates to a reversing device using a crane that grasps and inverts aggregate (shaped steel) attached to a mother mold (steel plate).

Conventionally, when a long object such as a ship's hull is turned over in a factory where the lift of the crane is low, the rope is usually 60cm high due to the relationship between the tension applied to the rope depending on the hanging angle and the compressive force acting in the horizontal direction. It is carried out within 20°. In this case, due to the safety standard restrictions on the installation angle of the wire 1 shown in Figure 1, the ear plate 3 of the base plate (steel plate) 2 is grasped with the clamp 4 (4 points), and the base plate is attached to the wire using two cranes. It was inverted via 1. In addition, 5 is the shaped steel attached to the base plate 2,
α is the hanging angle.

This invention aims to create a device that can be easily turned over with a single crane when long objects are repeatedly turned over in factories with low lifts. A frame balance that is rotatable about a base end and has a hanging piece to which a plurality of hanging tools are attached to the beam, a plurality of shaped steel clamping plates and guides each fixed to the legs, and the guide. a slide rod that is movable in the length direction of the leg guided by a plurality of mold steel clamps that are attached to the slide rod and that can adjust the gap between them and each of the mold steel clamp plates by moving the slide rod; A plate, a lever that is connected to the slide rod and rotates about a pin fixed to the leg to move the slide rod, and an engagement member that fixes the moving position of the slide rod to the leg. To provide a reversing device using a crane, which can easily reverse even a thin plate without bending, and can quickly and reliably perform reversing work.

The embodiments of the present invention will be explained below with reference to the drawings. Fig. 2 is a perspective view showing one embodiment of the device of the present invention, Fig. 3 is a side view of the same, and Fig. 4 is a detailed view of the main parts of Fig. 3. be. In the figure, reference numeral 6 denotes a frame balance, which is configured in a gate shape with legs 6a and beams 6b, and the base end of the leg 6a is rotatably supported by a fulcrum pin 8 on a fixed base 7.

A plurality of hanging pieces 9 are provided on the beam 6a, to which hanging tools can be attached.
In addition, a plurality of shaped steel contact plates 10 and guides 10a are fixed to the top and side surfaces of the legs 6a of the frame balance 6, respectively, and a slide rod 11 slides using the guides 10a as a guide. The position of the mold steel clamping plate 12 can be moved back and forth.

Further, a connecting plate 11a having an elongated hole 11b is fixed to the slide rod 11, and a screw 14 is connected to the elongated hole 11b via a pin 13. 15
is a pin, which serves as a fulcrum for the lever 14. Reference numeral 16 denotes an engagement portion between the leg 6a provided at one end of the slide rod 11 and the slide rod 11, and is fixed to the leg 6a using a removable pin, bolt, or nut 16a. Further, 17 is a steel plate, and 18 is a plurality of steel molds fixed in parallel to one side of the steel plate 17.

Next, the effect will be explained. First, attach the screw 14 to the pin 15.
When the slide rod 11 is rotated clockwise in FIG. 3 using the fulcrum as a fulcrum, the slide rod 11 moves to the right, creating a gap between the mold steel contact plate 10 and the mold steel clamping plate 12.

Next, the steel plate 17 to which the shaped steel 18 is fixed is placed on the frame balance 6 using a moving device such as a carrier or a crane.
In this case, the back part of the mold steel 18 should be placed near the mold steel contact plate 10.

Then, when the screw 14 is rotated counterclockwise,
A force is applied to the connecting plate 11a using the pin 15 as a fulcrum, and the slide rod 11 is moved to the left. Accordingly, the shape steel clamping plate 12 also moves to the left and engages with the shape steel 18 fixed to the steel plate 17. In this state, the slide rod 11 is fixed to the frame balance 6 by attaching a pin, bolt, or nut 16a to the engaging portion 16, and the hanging piece 9 is lifted by a crane (not shown) via a hanging tool such as a shackle, and the crane is moved. The frame balance 6 is reversed using the reversal fulcrum pin 8 as a fulcrum.

Next, remove the pin, bolt, or nut 16a, rotate the screw 14 clockwise, disengage the steel plate 17 from the reversing device, return the reversing device to its original position using a crane, and move on to the next work on the steel plate. . In this embodiment, the engaged state of the steel plate 18 is shown, but the steel plate 17
By changing the shape of the shape steel clamping plate 12 according to the shape of the shape steel attached to the shape steel, it is possible to adapt to various types of products.

Since the present invention is constructed as explained in detail above, it is possible to safely perform the reversal operation with a single crane, and even thin plates can be easily reversed without bending.
In addition, the reversing work can be done quickly and reliably.
