Description

Technical Field

[0001] The utility model relates to the technical field of lifting and hoisting, in particular to a multi-purpose telescopic balance beam hoist. Background Art

[0002] Balance beam is an important part of hoisting equipment and is widely used in lifting and hoisting. Balance beam is also called iron shoulder pole. It can be used to maintain the balance of hoisted components or equipment to prevent the sling from damaging the equipment; shorten the height of the sling and reduce the lifting height of the lifting equipment; reduce the horizontal pressure on the equipment during lifting to avoid damage to the equipment; when multiple machines are lifting, the use of balance beam can also reasonably distribute or balance the load of each lifting point.

[0003] Traditional balance beam slings are assembled in fixed length, integral or on-site splicing, usually composed of 3-4 sections, also known as modular balance beams. The balance beam system is connected by bolts, which has the disadvantages of being inconvenient for transportation, inconvenient for storage on the construction site, and labor-intensive during assembly, requiring multiple people to cooperate in assembly. Disassembly after use is time-consuming and labor-intensive, and is not economical to use.

[0004] In the sintering machine, during the installation of the SCR denitrification device module of the flue gas purification system and the installation of the cathode and anode of the main electrostatic precipitator device, it is often necessary to balance the hanging parts, and sometimes it is necessary to adjust the hanging parts to a precise horizontal state or prevent the deformation of the components during the lifting process. Therefore, in order to achieve basic balance of the hanging parts, different tying methods of the slings can be used, such as the sling series method or the use of two equal-length slings for lifting, etc. However, in order to make the hanging parts reach a precise horizontal state, some tools that can be fine-tuned are required. These lifting tools cannot guarantee the balance of the lifting equipment well. The usual practice is to use a balance beam lifting equipment, but the current balance beam lifting equipment is not convenient enough when adjusting the balance, and the adjustment of the lifting equipment on both sides of the balance beam is too complicated. Therefore, it is of great practical significance to design a multi-purpose retractable balance beam lifting equipment to meet the needs of different working environments and improve the lifting efficiency and safety.

Through the telescopic function of the telescopic beam 2, it can adapt to the lifting requirements of different lengths.

[0025] In this embodiment, if Figure 1As shown, bolts 5 are passed through the first through hole 11 and the corresponding second through hole 21 to fix the main beam 1 and the telescopic beam 2. The bolts 5 are installed to adjust the extension or contraction of the telescopic beam 2, and the operation is simple.

[0026] In this embodiment, if Figure 5 As shown, a first slot 31 matching the main beam 1 is provided in the middle of the first lifting ear 3, and three first lifting holes 32 are provided on the first lifting ear 3 at the periphery of the first slot 31, which is convenient for processing. The upper first lifting hole 32 is used for lifting by lifting equipment, and the lower two first lifting holes 32 are used for auxiliary lifting equipment or components.

[0027] In this embodiment, if Figure 6 As shown, a second slot 41 matching the telescopic beam 2 is provided in the middle of the second lifting ear 4, and three second lifting holes 42 are provided on the second lifting ear 4 at the periphery of the second slot 41, which is convenient for processing. The upper second lifting hole 42 is used for lifting equipment, and the lower two second lifting holes 42 are used for auxiliary lifting equipment or components.

[0028] In this embodiment, if Figure 5-6 As shown, the first lifting lug 3 and the second lifting lug 4 are both made of 12 mm thick steel plates, which are easy to process.

[0030] In this embodiment, if Figure 4 As shown, the telescopic beam 2 is made of square steel of 220 mm×220 mm×12 mm, which is easy to process.

[0031] In this embodiment, if Figure 1 As shown, the main beam 1 adopts 250mm×250mm×12mm square steel, and the first through holes 11 are processed at equal intervals on the main beam 1; the telescopic beam 2 adopts 220mm×220mm×12mm square steel, and the second through holes 21 are processed at equal intervals. The first lifting ear 3 and the second lifting ear 4 are both made of 12mm thick steel plate, and the first slot 31 and three first lifting holes 32 are processed on the first lifting ear 3, and the second slot 41 and three second lifting holes 42 are processed on the second lifting ear 4.

If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it.
