Abstract

The utility model discloses a multi-function lifting tool, comprising a bottom plate, a support bar and a self-suspension component. The support bar is connected with the bottom plate; the upper end of the support bar is connected with the self-suspension component; the self-suspension component comprises a suspension arm; the tail end of the suspension arm is provided with a hoisting ring; a support arm is arranged between the suspension arm and the support bar; an adjusting bar is arranged between the support bar and the bottom plate; two ends of the adjusting bar are provided with a cassette and the adjacent cassettes are connected with each other by a bolt. The multi-function lifting tool has the advantages of reasonable design, skillful conception, compact structure, being convenient to be combined and disassembled, high work efficiency, small labor intensity and safe and reliable work; the adjusting bar can be increased and decreased suitably to meet the requirements of different lifting heights according to the working condition demand; the multi-function lifting tool is particularly adapted to be used in working condition that large scale lifting tools such as a crane, etc. can not enter the spot.

Description

The multifunctional crane holding tool

Technical field:

The utility model relates to the installation and maintenance device of electric power system, and employed lifting device is installed and changed to the equipment such as TYD, OC that relate in particular in the transformer station.

Background technology:

Continuous development along with electric power system, the workload of the overhaul of equipment such as the TYD in transformer station, OC, technological transformation, replacing is more and more, but owing to do not consider the circumferential highway and the necessary access path in line side during the design planning of transformer station, cause when circuit PT, OC work or replacing, large-scale lifting device does not enter the scene, just because of the restriction that is subjected to site space, make this operating technology difficulty big, dangerous high, not only hinder construction schedule, also can cause the certain economic loss.Existing method is to use the manpower gin pole, but this lifting device is influenced by earth construction, and lifting such as the equipment of 110KV voltage transformer structure just needs 14 people's continuous operations to finish in 8 hours for one group, and operating efficiency is low, need personnel more, poor safety performance.

The utility model content:

Technical problem to be solved in the utility model provides a kind of multifunctional crane holding tool at above deficiency exactly, this instrument is the rotatable lifting combination tool of only bar more piece, rationally utilized the framework of equipment such as TYD, OC, fully take into account the confined space in place, have easy accessibility, small and exquisite flexibly, high efficiency, characteristics such as safe and reliable, solved a difficult problem that makes lifting device, crane can't enter the working site because of the space is narrow and small.

Technical solution adopted in the utility model is:

A kind of multifunctional crane holding tool, by base plate, support bar with hang assembly certainly and constitute, support bar is connected on the base plate, and the upper end of support bar is connected with from hanging assembly, hangs assembly certainly and includes arm, and the end of arm has suspension ring.

Sturdy and durable in order to make from hanging assembly, have support arm between arm and the support bar.

In order to make from hanging relative rotation between assembly and the support bar, have second bearing between arm and the support bar, have clutch shaft bearing between support arm and the support bar.

For the ease of dismounting, the bottom of support bar has deck, and deck is connected with bed bolt.

In order to adapt to hoisting height, have adjusting lever between support bar and the base plate, the two ends of adjusting lever are equipped with deck, and adjacent deck bolt connects.

For the scope of application is more extensive, still can not work under the planar device framework situation having, all be connected with Fixing clamp-seat on base plate and the support bar, the Fixing clamp-seat cross-under is on vertical framework.

The beneficial effect that the utility model can reach is:

1, the utility model reasonable in design, be skillfully constructed, compact conformation, be convenient to make up dismounting, especially be adapted to large-scale lifting device such as crane and can't enter under the on-the-spot operating mode and use.

2, the utility model high efficiency, labour intensity are little, safe and reliable.

3, the utility model can suitably increase and decrease adjusting lever according to the operating mode needs, to reach the needs that satisfy different hoisting heights.

4, the utility model can rotate with support bar relatively from hanging assembly, makes operating efficiency improve, and adaptability is strong, has saved a large amount of manpower and materials.

Description of drawings:

Fig. 1 is the structural representation of embodiment 1 of the present utility model.

Fig. 2 is the structural representation of embodiment 2 of the present utility model.

Fig. 3 is the structural representation of embodiment 3 of the present utility model.

Embodiment:

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

Embodiment 1: as multifunctional crane holding tool among Fig. 1, support bar 2 is fixed on the base plate 1 by bolt 8, the upper end of support bar 2 connects from hanging assembly by clutch shaft bearing 3, include arm 5 from hanging assembly, the end of arm 5 has suspension ring 6, have support arm 7 between arm 5 and the support bar 2, have second bearing 4 between arm 5 and the support bar 2.During use, at first base plate 1 is fixedly mounted on the equipment frame, then support bar 2 be connected carry out on the base plate 1 fastening, the 3rd the step be to be fixed on the support bar 2 with hanging assembly certainly, can begin lifting work.

Embodiment 2: as multifunctional crane holding tool among Fig. 2, basic structure is with embodiment 1, and difference is, because the height of lifting needs, has increased by two joint adjusting levers 10, and the two ends of adjusting lever 10 are equipped with deck 9, and adjacent deck bolt connects.

Embodiment 3: as multifunctional crane holding tool among Fig. 3, basic structure is with embodiment 2, and difference is, because the intensity of lifting need reach the existence of vertical framework 11, all be connected with Fixing clamp-seat 12 on base plate 1 and the adjusting lever 10, Fixing clamp-seat 12 cross-under are on vertical framework 11.

Need to prove: the scope of application of the present utility model is not limited to the installation and the replacing of the equipment such as TYD, OC in the transformer station, all can use so long as large-scale lifting device such as crane can't enter under the on-the-spot operating mode.
