Description

Multifunctional lifting tool

Technical field:

The utility model relates to an installation and maintenance device of a power system, in particular to a hoisting tool used for installation and replacement of TYD, OC and other equipment in a substation.

Background technique:

With the continuous development of the power system, the workload of overhaul, technical transformation and replacement of TYD, OC and other equipment in the substation is increasing. However, the ring road on the line side and the necessary maintenance are not considered in the design and planning of the substation. As a result, large hoisting tools cannot enter the site when the line PT and OC are working or being replaced. It is precisely because of the limitation of site space that this work is technically difficult and dangerous, which not only hinders the construction progress, but also causes a certain economic loss. The current method is to use a manpower pole, but the hoisting tool is affected by the ground structure, and hoisting a group of equipment such as a 110KV voltage transformer structure requires 14 people to work continuously for 8 hours to complete, the work efficiency is low, and more people are needed. Poor safety performance.

Utility model content:

The technical problem to be solved by the utility model is to provide a multifunctional hoisting tool for the above deficiencies. The tool is a single-rod multi-section rotatable hoisting combination tool. It has the characteristics of convenient disassembly and assembly, compact and flexible, high work efficiency, safe and reliable work, etc. It solves the problem that hoisting tools and cranes cannot enter the work site due to the small space.

The technical scheme that the utility model takes is:

The utility model relates to a multifunctional hoisting tool, which is composed of a bottom plate, a support rod and a self-hanging assembly. The support rod is connected to the bottom plate. The upper end of the support rod is connected with a self-hanging assembly.

In order to make the self-hanging assembly strong and durable, there is a support arm between the boom and the support rod.

In order to make relative rotation between the self-hanging assembly and the support rod, there is a second bearing between the boom and the support rod, and a first bearing between the support arm and the support rod.

In order to facilitate disassembly and assembly, the bottom of the support rod has a deck, and the deck is connected with the bottom plate by bolts.

In order to adapt to the hoisting height, there is an adjustment rod between the support rod and the bottom plate, and both ends of the adjustment rod are provided with decks, and the adjacent decks are connected by bolts.

In order to have a wider range of use and can still work without a plane equipment frame, the base plate and the support rod are connected with a fixed card seat, and the fixed card seat is connected to the vertical frame.

The beneficial effect that the utility model can reach is:

1. The utility model is reasonable in design, ingenious in conception, compact in structure, easy to assemble and disassemble, and is especially suitable for working conditions where large hoisting tools such as cranes cannot enter the site.

2. The utility model has high working efficiency, low labor intensity, safe and reliable work.

3. The utility model can appropriately increase or decrease the adjustment rod according to the needs of working conditions, so as to meet the needs of different hoisting heights.

4. The self-hanging assembly and the support rod of the utility model can rotate relatively, which improves the work efficiency, has strong adaptability, and saves a lot of manpower and material resources.

Fig. 2 is a schematic structural view of Embodiment 2 of the present utility model.

Fig. 3 is a schematic structural view of Embodiment 3 of the present utility model.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

Embodiment 1: As shown in Figure 1, the multifunctional hoisting tool, the support rod 2 is fixed on the base plate 1 by bolts 8, and the upper end of the support rod 2 is connected to the self-hanging assembly through the first bearing 3. The self-hanging assembly includes a boom 5, and the suspension There is a suspension ring 6 at the end of the arm 5 , a support arm 7 is provided between the boom 5 and the support rod 2 , and a second bearing 4 is provided between the boom 5 and the support rod 2 . When in use, the base plate 1 is first fixedly installed on the equipment frame, and then the support rod 2 is connected to the base plate 1 for fastening. The third step is to fix the self-hanging component on the support rod 2, and the hoisting work can be started.

Embodiment 2: as shown in Figure 2, the multifunctional hoisting tool, the basic structure is the same as that of Embodiment 1, the difference is that, due to the height requirements of hoisting, two adjustment rods 10 are added, and the two ends of the adjustment rod 10 are all provided with decks 9 , Adjacent decks are bolted.

Embodiment 3: As shown in Figure 3, the multifunctional hoisting tool, the basic structure is the same as that of Embodiment 2, the difference is that, due to the strength requirements of the hoisting and the existence of the vertical frame 11, the base plate 1 and the adjustment rod 10 are connected with fixed clips 12. The fixed card base 12 is passed through the vertical frame 11.

It should be noted that the scope of application of the utility model is not limited to the installation and replacement of TYD, OC and other equipment in the substation, as long as the large lifting tools such as cranes cannot enter the site, it can be used.
