Description

A kind of hanging beam of adjustable lifting range

Technical field

The utility model relates to lifting tooling field, in particular to a kind of hanging beam of adjustable lifting range.

Background technique

Hanging beam is the very extensive tool of utilization in production operation usually, however different workpiece, different rulers It is very little, it is necessary to different lifting position, and for large-scale hanging beam, if in hanging beam lower surface welded rails from the beginning to the end, Will result in very big waste, increase cost, thus design one hanging beams for being suitable for a variety of lifting positions be very it is necessary to.

Utility model content

To overcome above-mentioned deficiency, the utility model is intended to provide a kind of hanging beam of adjustable lifting range, is lifting by crane each knot When the workpiece of structure size, suspension centre can have been balanced, safety, it is steady, effectively carry out lifting operation.

The technical solution that the utility model solves are as follows: a kind of hanging beam of adjustable lifting range of the utility model, mainly It is made of the girder lower surface pulley blocks that are slidably connected, innovative point is: further including 4 groups of tracks, the track symmetrically divides two-by-two Girder lower surface two sides are distributed in, and are welded to connect with girder lower surface, interval opens up several threaded holes on the track；It is several It holds out against and uses bolt, described hold out against mainly is made of U-shaped sliding block in sliding block opening threaded connection bolt with bolt；It is described to hold out against use Bolt is slidably connected in sliding block opening with track.

Preferably, shown pulley blocks are slidably connected by track and girder.

Preferably, the bolt matches with threaded hole.

Utility model has the advantages that

A kind of hanging beam of adjustable lifting range of the utility model, rationally, structure is simple, easy to make for design.Effectively keep away Welded rails from the beginning to the end are exempted under large-scale hanging beam, have saved cost, while when facing each specification large-scale workpiece, can balance Good each lifting point position is conducive to control actual condition, improves balance of the workpiece in lifting, transport process, avoids The generation of rigging defective work piece event, the load of each suspension centre of reasonable distribution reduce the load of crane receiving.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the hanging beam of the adjustable lifting range of the utility model.

Fig. 2 is the structural schematic diagram of Fig. 1 middle orbit part.

In figure: 1- girder；2- pulley blocks；3- track；4-, which is held out against, uses bolt；5-U type sliding block；6- bolt；7- threaded hole.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly, it is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

A kind of hanging beam of adjustable lifting range of the utility model, is mainly slidably connected pulley blocks 2 by 1 lower surface of girder It constitutes, as shown in Figure 1,1 overall length of girder is 38m, crane capacity 200T, in order to reasonably adjust lifting range, this is practical Novel that 4 groups of tracks 3 have also been devised, the design bearing capacity of every group of track 3 is 50T, which is symmetrically distributed in girder 1 two-by-two Lower surface two sides, and be welded to connect with 1 lower surface of girder, and pulley blocks 2 are slidably connected by track 3 with girder 1；Using this Design has saved cost so as to avoid the mode of welded rails 3 from the beginning to the end under large-scale hanging beam.

The utility model have also been devised it is several hold out against with bolt 4, as shown in Fig. 2, this holds out against with bolt 4 mainly by U-shaped cunning Block 5 is constituted in sliding block opening threaded connection bolt 6；And it holds out against and is slidably connected with bolt 4 in sliding block opening and track 3.

As shown in Fig. 2, interval opens up several threaded holes 7 on the track 3, and bolt 6 matches with threaded hole 7.

The design that the utility model uses pulley blocks 2 to be slided in track 1, to meet the lifting point position of each workpiece It is required that being held out against with 2~3 groups and being held out against with bolt 4 to pulley blocks 2 after meeting lifting point position, prevent pulley blocks 2 random It is slided in track 3, it is ensured that the balance of suspension centre meets safe and stable, effective when lifting by crane；Be conducive to control practical work simultaneously Condition improves balance of the workpiece in lifting, transport process, avoids the generation of rigging defective work piece event, reasonable distribution The load of each suspension centre reduces the load of crane receiving.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications, above-mentioned vacation can also be made If these improvements and modifications also should be regarded as the protection scope of the utility model.
