Iron plate hanging fixture

Abstract

To provide a steel plate hoisting tool which prevents accidents of falling during work such as hoisting a single plate with a crane and placing it on a table or sorting it in the metal processing industry, steel material trading, etc. [Solution] The steel plate hoisting tool, which can hoist only one plate, is composed of a hoisting hook 1, a hook-through pipe 2, and a slinging wire 3. The hoisting hooks are connected to the hook-through pipe (pipe) in a staggered manner so that two of them hang down, and a slinging wire (wire) passes through the two hoisting hooks in a continuous manner. When the plate is hoisted, the hoisting hooks tilt according to the hoisting angle of the wire, and while holding the pipe at their inner corners, a force that tries to move them closer to each other acts inward, holding the plate (transported object) firmly, making it less likely that a fall accident will occur. The part where the wire of the hoisting hook passes through is a round pipe, which makes it less likely for the wire to become bent, and the hook-through pipe has a stopper to prevent the hoisting hook from coming off.

Description

Summary of the Invention [Problem to be solved by the invention] In the metal processing industry and steel trading, it is common to have to hoist a single board with a crane and place it on a table or sort it. Because it is so common, people tend to want to simplify the process. Even if there are rules set in the workplace, when you are busy, you end up just hanging a single hoist around the middle of the board and balancing it with one hand. This is very dangerous. But what if that one sling was a tool you could trust 100%? Is the work dangerous? The development of lifting equipment that protects "employees who always try to take the easy way out and do not follow workplace rules" is essential to protecting human lives. [Means for solving the problem] It is a "steel plate lifting device for lifting only one plate." The distinctive feature of this lifting device is its structure. ▲1▼ Lifting hooks are connected to ▲2▼ Hook-through pipes (pipes) in a staggered manner, with ▲3▼ Lifting wires (wires) running continuously through the two lifting hooks. When the plate is lifted, ▲1▼ Lifting hooks tilt according to the lifting angle of the wires, and hold the pipes with their inner corners. Furthermore, the forces that try to shrink together (forces that try to become the shortest distance) act inward to hold the plate (transported object) firmly, which results in less chance of a fall. ▲1▼ Hanging hook and ▲2▼ Hook-through pipe each have the following characteristics. ●▲1▼The part through which the wire of the hanging hook passes is made of a round pipe, which prevents the wire from becoming bent. ●▲2▼The hook-passing pipe is equipped with a stopper to prevent the hanging hook from falling out. Effect of the Invention Okada Sheet Metal Works, the company that developed this device, has been using this hoist for about 20 years when plates must be hoisted one by one by a crane onto the table of a laser processing machine. During that time, the device has been upgraded several times to improve safety. Thanks to this, there have been no accidents of plates falling. I believe that there are many companies out there that are troubled by similar issues, and I hope that our "steel plate hoist for suspending only one plate" will become widespread before someone is injured. [Brief description of the drawings] [Figure 1] Overall and detailed views DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In metal processing industries, steel trading, etc., when work requires lifting plates one by one with a crane EXAMPLES The applicant in this case, Okada Sheet Metal Industry Co., Ltd., has been using the product for approximately 20 years and its safety has been proven.

Claims

[Claim 1] It is a "steel plate lifting device for lifting only one plate." The distinctive feature of this lifting device is its structure. ▲1▼ Lifting hooks are connected to ▲2▼ Hook-through pipes (pipes) in a staggered manner so that two of them hang down. ▲3▼ Sling wires (wires) run continuously through the two lifting hooks. When the plate is lifted, ▲1▼ the lifting hooks tilt according to the lifting angle of the wires, and hold the pipes with their inner corners. Also, the forces that try to shrink together (the forces that try to become the shortest distance) act inward to hold the plate (transported object) firmly, which results in less chance of a fall. The hanging hook and the hook-through pipe each have the following characteristics: ●▲1▼The part through which the wire of the hanging hook passes is made of a round pipe, so the wire is less likely to become bent. ●▲2▼The hook-passing pipe is equipped with a stopper to prevent the hanging hook from falling out.
