Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In the field of metallurgy, an overhead crane is usually disposed in a factory building, so that an object required in a production process can be shifted in position. However, due to the influence of production demands, buildings often exist above some production areas in a factory building, so that shielding exists between the corresponding production areas and the crown block track, a hoisting blind area of the crown block is formed, the object transfer difficulty of the corresponding production areas is increased, and further improvement of production efficiency is limited. For example, the hot rolling process generally requires that a thickness gauge is arranged at the outlet of the finishing mill, so that a layer cooling output roller way can be positioned below a thickness gauge room, and then a crown block can pass through the position right above the layer cooling output roller way, but cannot directly load and unload objects at the layer cooling output roller way in a crossing manner, and as the surface quality requirement on strip steel is higher and higher, the importance of stable running of a roller way motor is more and more remarkable, the maintenance and replacement work of the roller way motor is more and more frequent, and under the condition that the crown block cannot directly act on the layer cooling output roller way, the replacement and maintenance work of the motor can consume more manpower and time, so that the production continuity is easily influenced, and the further improvement of the production efficiency is limited.

In view of this, as shown in fig. 1 to 3, according to a first aspect of an embodiment of the present disclosure, a hoisting tool is provided, including: a lifting beam 100 having a first lifting side 101 and a second lifting side 102 facing away from each other; a counterweight assembly 400 provided to the hoist beam 100; the first hoisting assembly 200 is arranged on the first hoisting side 101 and is used for hoisting the overhead crane hoist 10'; the second hoisting assembly 300 is arranged on the second hoisting side 102 and is used for being connected to the piece 20' to be transferred; wherein, along the length direction of the hoist beam 100, the first hoist assembly 200 is located between the weight assembly 400 and the second hoist assembly 300, and a space is formed between the first hoist assembly 200 and the second hoist assembly 300.

The hoisting tool provided by the embodiment of the disclosure comprises a hoisting beam 100, a first hoisting assembly 200, a second hoisting assembly 300 and a counterweight assembly 400.

Wherein, hoist and mount roof beam 100 is formed with first hoist and mount side 101 and second hoist and mount side 102, and first hoist and mount side 101 and second hoist and mount side 102 deviate from each other, first hoist and mount subassembly 200 and second hoist and mount subassembly 300 set up respectively in first hoist and mount side 101 and second hoist and mount side 102, first hoist and mount subassembly 200 can be used for hanging to establish on overhead traveling crane hoist 10' in practical application, thereby hoist and mount frock can take place the displacement under the drive of overhead traveling crane, second hoist and mount subassembly 300 can be used for connecting to wait to shift piece 20' in practical application, thereby hoist and mount frock can drive to wait to shift piece 20' synchronous motion.

It will be appreciated that, since the first lifting side 101 and the second lifting side 102 are away from each other, when the lifting assembly is lifted by the overhead travelling crane, the first lifting side 101 may be located above the second lifting side 102 along the gravity direction, and accordingly, the second lifting assembly 300 may be located at a relatively lower position, so as to facilitate ground loading and unloading of the workpiece 20' to be transferred by the lifting tool.

The counterweight assembly 400 is arranged on the lifting beam 100, and the first lifting assembly 200 is positioned between the counterweight assembly 400 and the second lifting assembly 300 along the length direction of the lifting beam 100, so that under the condition that the second lifting assembly 300 is connected with the piece 20 'to be transferred, the lifting tool can balance the stress of the lifting beam 100 in the gravity direction by using the counterweight assembly 400, so that the lifting beam 100 can be guaranteed to have higher levelness, the possibility that the lifting beam 100 is inclined greatly in the use process is reduced, and the safe and reliable transfer process of the piece 20' to be transferred is guaranteed.

Meanwhile, a space is further formed between the first hoisting assembly 200 and the second hoisting assembly 300 along the length direction of the hoisting beam 100, so that in the process that the hoisting tool connected with the piece to be transferred 20' is hoisted by the overhead travelling crane, a space distance can be formed between the piece to be transferred 20' and the overhead travelling crane along the length direction of the hoisting beam 100, so that dislocation is formed between the piece to be transferred 20' and the overhead travelling crane in the horizontal direction, and when a shielding object exists between the target transfer position of the piece to be transferred 20' or the placing position before transfer and the overhead travelling crane track, the hoisting tool can utilize the space between the first hoisting assembly 200 and the second hoisting assembly 300 along the length direction of the hoisting beam 100 to avoid the shielding object, so that the piece to be transferred 20' can be conveniently transferred to the lower part of the shielding object or be transferred to other areas from the lower part of the shielding object, the hoisting range of the overhead travelling crane in a factory building can be enlarged, the production efficiency can be improved, and the labor cost of object transfer operation can be reduced.
