Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a hook used for lifting construction materials and the like.

[0002]

2. Description of the Related Art Conventionally, a lifting hook used to lift a building material has a shape as shown in FIG.

[0003]

However, in the case of the lifting hook as shown in FIG. 7, when the building material 11 or the like that has been lifted is fixed at the lifting position and then removed, the person is raised to the lifted position. Since it is necessary to remove the hanging belt 13, it is extremely dangerous and difficult. Therefore, an object of the present invention is to provide a lifting hook that solves the above problems.

[0004]

According to the present invention, there is provided a lifting hook characterized in that a pressing member and a movable member are rotatably attached to a U-shaped member.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. 1 is a front view of the lifting hook of the present invention, FIG. 2 is a right side view of the lifting hook of the present invention, and FIG. 3 is a left side view of the lifting hook of the present invention. The present invention comprises a U-shaped member 2, a movable member 3 and a pressing member 4,
The pressing member 4 is rotatably attached to the vertical portion 2b of the U-shaped member 2 by a pin 5, and the movable member 3 is rotatably attached by a pin 6 between the left and right protrusions 2c and 2d of the U-shaped member 2. It is installed. The movable member 3 is formed with a lifting belt insertion hole 3c for inserting and fixing a lifting belt for lifting the building material 11 as a material to be transported. In addition, the lifting belt 1 is provided in the U-shaped member 2.
An insertion hole 2f for inserting 2 is formed. Mounting hole 4c formed in lever-4a of the pressing member 4
A ring 7 for attaching a rope 8 is attached to the. The rope 8 may be directly attached to the attachment hole 4c. The horizontal portion 3b forming the movable member 3 is fixed to the rising portion 3a with a screw 3e. Reference numeral 2e is a fitting groove for fitting the tip of the rising portion 3a of the movable member 3 into the tip of the upper protruding portion 2a so as not to loosen. Reference numeral 9 is an inspection hole, and this inspection hole 9 is a hole for removing foreign matters such as stones when stones or the like enter inside during use and the movable member 3 does not operate.

FIG. 4 is a front view showing a state in which a movable member rotatably attached to a U-shaped member of the lifting hook according to the present invention is rotated, and FIG. 5 is a part of the lifting hook according to the present invention. FIG. As shown in FIG. 4, the movable member rotates in the arrow g and arrow h directions, and the pressing member 4 also rotates in the arrow c and arrow d directions as shown in FIG. . . As shown in FIG. 5, the U-shaped member 2
A coil spring 10 is mounted inside the device to constantly press the pressing member 4 toward the ring mounting hole 4c. The movement of each member will be described below with reference to FIGS. 4 and 5. When the rope 8 is pulled in the direction of arrow a, the pressing member 4 moves in the direction of arrow c, and the pressing portion 4b moves in the direction of arrow e. Therefore, the state in which the pressing portion 4 is pressed by the tip of the pressing portion 4 is released. As shown in FIG. 4, the movable member 3 moves in the direction of the arrow g, and the insertion hole 2f is opened. In order to return to the original state, that is, to return to the state of FIG. 1, when the movable member 3 is pushed back in the direction of the arrow h by hand, it is pushed back by the horizontal portion 3b of the movable member 3, and the pushing portion 4b of the pushing member 4 is pushed. When is pushed back, it moves in the direction of arrow f, and the tip of the pressing portion 4b presses the left end of the horizontal portion 3b on the horizontal portion 3b, and returns to the original state. In this case, the lever-4a moves in the direction of arrow d. Figure 4
As shown in FIG. 3, one end of the horizontal portion 3 is rotatably attached to the movable member 3 by the pin 3g, and the other end is erected on the standing portion 3.
It is fixed to a by a screw 3. When attaching the hoisting rope 12 to the insertion hole 3c, loosen the screw 3f to move the horizontal portion in the direction of arrow i, insert the hoisting rope 12 into the insertion hole 3c, and then descend in the direction of arrow j to stand up. Screw on the portion 3a.

FIG. 6 is a use state diagram showing a state in which a building material or the like is hoisted by the hoisting hook according to the present invention. As shown in the figure, when hoisting the building material 11 or the like at a high place, First, the tip of the lifting belt 12 is inserted through the insertion hole 3c of the lifting hook 1 according to the present invention, and the building material 11 for transportation is tied to the attached lifting belt 12. After the binding belt 12 that has been tied up is inserted through the insertion hole 2f, the belt 12 is attached to a crane vehicle and lifted to a predetermined high position. After being lifted to a predetermined position and attached and fixed at a predetermined position, the rope 8 is pulled to move the movable member 3 to the position shown in FIG.
The belt 12 is rotated as shown in FIG. 2 to be detached from the insertion hole 2f, so that the building material 11 etc.
The belt 12 can be easily removed after fixing the.

[0013]

Since the present invention has the above-described structure, the following effects can be obtained. First, there is an effect that it is possible to easily place a building material or the like, which has been lifted at a predetermined high position, in a position where the building material is lifted. Secondly, there is an effect that it is possible to safely and easily transport the hoisted building materials and the like to a high place. Third, there is an effect that it is extremely safe because it does not fall even when the building material is being lifted. Fourthly, when this hook is used, there is an effect that a building material or the like as a material to be transported is not damaged and the coating is not peeled off.
