JPH07285783A - Suspension tool for electrically-operated hoist - Google Patents

Abstract

PURPOSE:To suspend a cargo in a constantly horizontal state by a method wherein the position of a pulley attached to the suspension tool of an electrically-operated hoist is vertically movable and the position of a hook is regulatable according to the suspension position of a cargo. CONSTITUTION:A chain 2 to rotate a sprocket with the aid of a motor for an electrically-operated hoist body 1 and an E-shape suspension tool 3 is elevated by winding and unwinding of a chain 2. Pulleys 7 and 7' are rotatably supported to the two end parts of the suspension tool 3 by means of disengageable pins 8 and 8'. The pins 8 and 8' are selectively inserted in some of a plurality of vertical holes 10 and 10' according to the suspension position of the suspension tool 3. Chains 4 and 4' the upper ends of which are fixed to the suspension tool 3 are suspended through pulleys 7 and 7' and rotatable hooks 6 and 6; are attached to the ends on the other side. As noted above, by varying the vertical positions of the pulleys 7 and 7', even a cargo 9 whose the heights of the suspension positions are different from each other can be suspended in a horizontal state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoist for an electric hoist.

[0002]

2. Description of the Related Art In the case of the conventional method, a hanging device for exclusive use is attached to a chain hanging on a hoisting machine to wind or lower a load. There was a drawback that the luggage would tilt.

Here, regarding the above-mentioned prior art,
Description will be made based on an example of FIG. 1 is an electric hoist body that can rotate a sprocket by rotating a motor, wind a chain 2, and rewind to wind and lower a load. Reference numeral 3 denotes a T-shaped suspender, which has a center portion attached to a chain 2 which is hooked on a sprocket, and has chains 4 and 4'having the same length attached to lower portions of both ends. Hangers 5 and 5'are attached to the lower portions of the chains 4 and 4 '.
Reference numerals 6 and 6'represent hooks for suspending luggage, and suspenders 5 and 5 '.
It is rotatably attached to.

Since the chains 4 and 4'are fixed to the hanger 3 and have a constant length, the heights of the hanging positions of the hooks 6 and 6'cannot be adjusted, so that the load 9 of the luggage 9 cannot be adjusted. When hanging loads such as those with different heights at the hanging position, the loads will tilt.

[0005]

SUMMARY OF THE INVENTION In order to solve the problems of the conventional method, the present invention provides a hanger that can adjust the position of the hook according to the hanging position of the load and can hang the load horizontally. The purpose is to provide.

[0006]

In order to solve the conventional problem, a structure is adopted in which a hook is moved up and down by attaching a pulley to the suspender 3 and moving the attachment position.

[0007]

[Operation] The vertical position of the hook can be adjusted by moving the pulley vertically.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As a suspender for an electric hoist for hoisting and lowering a load, the conventional product has a chain 4 and 4'having the same length attached to both ends of the suspender 3 as shown in FIG. However, there is a drawback that the luggage is inclined when it is hung up such that the height of the hanging position is different. On the other hand, in this embodiment, as shown in FIG.
As shown in (3), pulleys are attached to both ends of the E-shaped suspending tool 3, and the positions of the hooks can be moved up and down by moving the attachment positions, so that the luggage 9 can be hung without tilting. The present invention will be described below with reference to the embodiments shown in FIGS. First, in FIG. 2, reference numeral 1 denotes an electric hoist body capable of rotating a sprocket by rotating a motor, winding the chain 2 and unwinding to wind and lower a load. 3 is an E-shaped hanging device, and pulleys 7 are provided at both ends.
7'is rotatably attached by pins 8 and 8 '. Further, several holes 1 are provided in the vertical direction so that the pulleys 7 and 7'can be moved.
0, 10 'are provided. The chains 4 and 4'have the same length, and are engaged with the pulleys 7 and 7'and fixed at one end to the central portion of the suspender 3 and attached to the other ends with the suspenders 5 and 5 '. Hooks 6 and 6'are rotatably attached to the hangings 5 and 5 '.

FIG. 1 shows the pulley 7 moved upward. When the pulley 7 is moved in this manner, the distance from the end of the chain 4 fixed to the central portion of the hanging device 3 to the portion where the pulley 7 and the chain 4 mesh with each other and the portion where the pulley 7 and the chain 4 mesh with each other Since the sum of the distances to the lower part of the hanging device 3 becomes longer and the distance from the lower part of the hanging device 3 to the lower part of the hook 6 becomes shorter accordingly, the position of the hook 6 becomes higher accordingly. Therefore, even when a load such as a load 9 having a different height of a hanging position is lifted, it can be hung horizontally without tilting. When the inclination of the load is opposite, the pulley 7'should be similarly moved upward.

[0010]

The effects of the present invention are as follows.

1. You can adjust the height of the hook.

2. Even luggage with different hanging positions can be hung horizontally.
