Small-tonnage crown block winding drum hoisting tool

Abstract

The utility model relates to the technical field of crown block equipment application, in particular to a small-tonnage crown block drum hoisting tool, and aims to solve the problems that a fixed pulley at the head of a crane rod is close to a steel structure of a metallurgical plant roof during hoisting of an existing small-tonnage crown block drum, the hoisting height of a crane hook head is greatly limited, and the hoisting angle of a hoisting drum steel wire rope is too large; and the winding drum is easy to deflect and rotate, so that the safe hoisting is influenced. According to the tool, the crane is stopped at a hoisting position by determining crane hoisting condition allowable data and a hoisting space, a crane boom rod of the crane is extended to a specified height, a crane boom angle of the crane is raised to a preset angle, then the tool is hung on a crane lifting hook, and a winding drum is hung by using a shackle and a lifting rope, so that the included angle of the lifting hook and the lifting rope is as small as possible; and therefore, the risks of narrow hoisting space and rotation and deflection of the winding drum are solved.

Description

Technical Field

[0001] This utility model relates to the field of overhead crane equipment application technology, specifically to a small-tonnage overhead crane drum hoisting tool. Background Technology

[0002] Small-tonnage overhead cranes are core equipment for hoisting within production plants. When overhauling these cranes, online replacement of the crane drum is typically required. Currently, several issues arise during this process: Firstly, the fixed pulley at the crane boom is close to the steel structure of the metallurgical plant roof during hoisting, limiting the crane hook's lifting height and distance. This results in an excessively large hoisting angle for the wire rope, causing the drum to wobble and rotate, which is detrimental to safe hoisting. Secondly, the equipment is large in size and weight. Since the crane's function is hoisting, its drum is large in size and tonnage, and the high-altitude location makes replacement difficult. Utility Model Content

[0003] This utility model provides a small-tonnage overhead crane drum hoisting tool to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A small-tonnage overhead crane drum hoisting tool includes a hoisting plate with multiple hoisting holes on the edge side. Each hoisting hole at the bottom of the hoisting plate is connected to a shackle, and each shackle is also connected to a strap.

[0006] This utility model has the following beneficial effects:

[0007] This utility model is easy to operate, greatly reducing the safety hazards of lifting and replacing small-tonnage overhead crane drums while ensuring the safety of maintenance personnel. It also improves maintenance efficiency, shortens the maintenance period, and provides convenient conditions for the use of overhead cranes in other maintenance projects. Through the application of this tool, problems such as maintenance site, maintenance safety, efficiency, and labor intensity during drum replacement are solved. It is a professional tool that is easy to manufacture and process, low in cost, has significant on-site effects, is highly practical, and has strong potential for expansion. At the same time, this tool provides theoretical and practical basis for the overall replacement method of overhead crane drums in production plants, which is conducive to promotion. It can be used for corresponding lifting and replacement operations in other similar drum replacement maintenance projects, and can also be used in the installation, modification, and debugging of new overhead crane equipment.

[0011] 1. Lifting plate; 2. Lifting hole; 3. Shackle; 4. Crane hook; 5. Lifting rope; 6. Straps; 7. Drum. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-2 As shown, a small-tonnage overhead crane drum hoisting tool includes a hoisting plate 1. Multiple hoisting holes 2 are opened on the edge of the hoisting plate 1. Shackles 3 are connected to the hoisting holes 2 at the bottom of the hoisting plate 1, and each shackle 3 is also connected to a strap 6.

[0014] In practical applications, this utility model pre-determines the allowable data for crane lifting conditions and the lifting space, stops the crane in the lifting position, extends the crane boom to the specified height, and tilts the crane boom angle α to the preset angle. Then, this tool is connected to the crane hook head 4 through the lifting hole 2 with a lifting rope 5, and then connected and fixed to the drum 7 through the binding strap 6. After the drum 7 is tied, the lifting is carried out. During the installation and dismantling process, the auxiliary and set chain hoist is connected through the lifting hole 2 for dismantling, installation and adjustment, which effectively improves the work efficiency and safety.
