The wire rope is repeatedly disassembled during hoisting, which is troublesome.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the lifting sling, which is used for lifting the flange plate in an internal supporting manner, so that the flange plate is firmly lifted without damaging the flange plate, the lifting sling can be quickly disassembled, and the use efficiency is further improved.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model provides a jack-up hoist, includes the connecting axle, and connecting axle bottom mounting has limiting plate one, installs link mechanism on the connecting axle of limiting plate one upper end, and link mechanism includes at least a set of first connecting rod and a set of second connecting rod, and wherein, first connecting rod one end is articulated with the connecting axle, the other end is articulated with the backup pad, and second connecting rod one end is articulated with the backup pad, the other end is articulated with the sliding plate, and the sliding plate slides and sets up on the connecting axle.

The outer side wall of the supporting plate is fixed with an anti-slip pad.

And the upper end of the sliding plate is provided with a second limiting plate which is in threaded connection with the connecting shaft.

The utility model relates to a lifting sling, which has the following technical effects: adopt link mechanism to open or shrink the backup pad, the backup pad can be tightly fixed to single ring flange top, and the hoist and mount is accomplished to rethread lifting means, and this mode can be firm with the ring flange hoist and mount under the holistic prerequisite of ring flange not damaging, and need not to pass the pipeline just can hoist and mount the ring flange and have improved the efficiency of dress hanging greatly, convenient to use moreover, can dismantle fast when the hoist and mount, further improves availability factor.

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

fig. 1 is a schematic view of the structure of the present utility model (without the limiting plate).

Fig. 2 is a schematic structural view of the link mechanism (first state) in the present utility model.

Fig. 3 is a schematic structural view of the link mechanism (second state) in the present utility model.

Fig. 4 is a schematic structural view (with limiting plates) of the present utility model.

In the figure: the connecting shaft 1, the first limiting plate 2, the sliding plate 3, the pull ring 4, the supporting plate 5, the anti-slip pad 6, the flange plate 7, the connecting rod mechanism 8 and the second limiting plate 9.

Detailed Description

As shown in fig. 1, the lifting sling comprises a connecting shaft 1, wherein a connecting rod mechanism 8 is arranged on the connecting shaft 1, the connecting rod mechanism 8 comprises three groups of connecting rods, the three groups of connecting rods are distributed at intervals from top to bottom, each group of connecting rods is three, and three of the groups of connecting rods are uniformly distributed along the circumferential direction of the connecting shaft 1. Two groups of the three groups of connecting rods have the same structure and are first connecting rods 8.1, one end of each first connecting rod 8.1 is hinged with the connecting shaft 1, and the other end of each first connecting rod is hinged with the supporting plate 5. The two groups of connecting rods are in parallel in one-to-one correspondence. The other group of connecting rods are second connecting rods 8.2, one end of each second connecting rod 8.2 is hinged with the supporting plate 5, and the other end of each second connecting rod is connected with the sliding plate 3. At the level of the two sets of first links 8.1, the second links 8.2 are inclined upwards and the angle between them and the first links 8.1 is less than 15 degrees. A through hole is arranged in the middle of the sliding plate 3, the sliding plate 3 can freely pass through the connecting shaft 1, and the sliding plate 3 can slide up and down on the connecting shaft 1.

The bottom of the lowest connecting rod on the connecting shaft 1 of the connecting rod mechanism 8 is provided with a first limiting plate 2, and the lowest connecting rod is limited through the first limiting plate 2, so that the connecting rod is prevented from rotating downwards when the flange 7 is hoisted. This allows the link mechanism 8 to support the flange 7 when subjected to a downward force from the flange, preventing the flange 7 from falling.

When the flange 7 needs to be dismounted, the sliding plate 3 is pulled upwards, the connecting rod mechanism 8 can be contracted, the diameter of the lifting appliance is smaller than that of the flange 7, and the lifting appliance can be taken out from the inside of the flange 7.

Preferably, the outer side surface of the supporting plate 5 is provided with a non-slip mat 6, and the friction force between the non-slip mat 6 and the inner wall of the flange 7 is increased, so that the stability and the safety of the inner supporting sling during loading and hanging are improved.

Preferably, the upper end of the sliding plate 3 is provided with a second limiting plate 9, a pull ring 4 is arranged on the second limiting plate 9, a certain section of the corresponding connecting shaft 1 is provided with threads, and the second limiting plate 9 is in threaded connection with the connecting shaft 1. When the supporting plate 5 is unfolded to be hoisted, the limiting plate II 9 can limit the sliding plate 3, so that the sliding plate 3 is prevented from moving upwards, and the supporting plate 5 automatically contracts to be separated from the flange 7.

Working principle and process: the hanging ring at the upper end of the connecting shaft 1 is connected with the hanging hook of the lifting equipment, and the sliding plate 3 is driven to slide upwards on the connecting shaft 1, so that the connecting rod mechanism 8 integrally contracts, and the device is integrally placed in the flange plate. And then the limiting plate II 9 is rotated, the limiting plate II 9 moves downwards and pushes the sliding plate 3 to move downwards, so that each supporting plate 5 is gradually spread in the flange, the anti-slip pad 6 (rubber) of each supporting plate 5 is contacted with the inner wall of the flange 7, after the contact is firm, the lifting device lifts the flange, the limiting plate II 9 is rotated upwards after the flange is lifted and placed at a proper position, the sliding plate 3 moves upwards, and thus the connecting rod mechanism 8 contracts again, and the flange is dismounted.
