Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a saw blade hoisting tool device. Background Art

[0002] Hot saws are the primary cutting equipment in large-format bar production lines while the rolled material is still hot. They are primarily used for cutting heads, tails, and segments in subsequent processes. While they offer high cutting efficiency, they also result in rapid blade wear, frequent on-site replacement, and significant operator risk. Hot saws consist of a slide mechanism, main drive system, transverse mechanism, hydraulic lubrication system, and electronic control equipment. The main working component of the main drive is the saw blade, which directly cuts the steel. During production, depending on the type of steel, specification, and material, the saw blade typically needs to be replaced every 300-500 tons of material cut, resulting in frequent blade replacements. Since the saw blade is installed inside the saw cover, it is impossible to use clamps or conventional lifting equipment directly for cooperation after opening the side door of the guard cover. The following problems exist in the operation process of the simple disassembly and assembly lifting equipment: 1. The phenomenon of crooked pulling and slanting lifting is common, and it is very easy for the saw blade to fall off and injure people, which brings great safety hazards to on-site operators and poses a great risk to safe operations; 2. The operation process is complicated, and the replacement of saw blades takes a long time, which seriously affects the production efficiency of the rolling line and the effective operation rate of the equipment; 3. The saw blade operation method is rough and inefficient, the labor intensity of employees is high, and the job personnel are unstable, which to a certain extent affects the production efficiency and quality of the entire steel rolling process.

[0007] As a further solution of the present invention: the locking limit assembly includes a limit socket, a limit socket rod is fixedly provided at one end below the limit socket, and a limit handle is fixedly provided above the limit socket.

[0008] As a further solution of the present invention: the saw blade assembly includes a saw blade body, the outer side of the saw blade body is provided with a hanging hole, and the middle of the saw blade body is provided with a middle mounting hole.

[0009] As a further solution of the present invention: the center point of the lifting through hole is adapted to the anti-slip annular groove, the rectangular plug-in hole is adapted to the plug-in rectangular plug-in rod, and the number of the limiting plug-in holes is four, which are opened on the upper and lower sides of the internal rectangular plug-in holes at one end below the C-shaped lifting frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model discloses that by holding the limit part handle, the limit plug rod is aligned with the limit plug hole and inserted until it passes through the limit plug hole of the rod body, the anti-falling assembly can be quickly installed on the lifting frame assembly, and it can also be conveniently replaced in the event of damage in the later stage. When lifting, the lifting hole in the saw blade assembly is passed through the anti-falling lifting head in the anti-falling assembly and buckled into the anti-falling annular groove, which can play a certain anti-falling effect during lifting. At the same time, a safety chain or safety rope is connected to the outer side of the saw blade assembly in the anti-falling annular groove and connected to the upper lifting seat above, so as to achieve a further anti-falling effect. In addition, the C-shaped opening structure is designed to facilitate the disassembly and assembly of the saw blade inside the saw cover, which improves the work efficiency. The lifting device can effectively prevent the saw blade from being slanted or tilted during installation and disassembly, thus improving the safety level of the site and better protecting the safety of the operators. The lifting device is convenient and fast, which shortens the downtime of a single saw blade replacement and increases the production time of the rolling line, laying a good foundation for the implementation of production and efficiency improvement. The daily maintenance workload is small, the operation is convenient and the safety factor is large. The designed and manufactured hot saw blade disassembly and assembly hoist has strong operability, simple structure, safety and reliability, and is suitable for the lifting of saw blade-like structural parts, and is worthy of promotion and use in the next step.
