In the description of the present utility model, unless explicitly defined otherwise, terms such as arrangement, installation, connection, etc. should be construed broadly and the specific meaning of the terms in the present utility model can be reasonably determined by a person skilled in the art in combination with the specific contents of the technical scheme.

As shown in fig. 1 and 2, a reversible lifting appliance according to an embodiment of the present utility model includes a clasping mechanism, a swing lifting mechanism 8 and lifting lugs 9.

The enclasping mechanism comprises a first main arc section 1 and a second main arc section 4 which are oppositely arranged and can be enclasped together. The first main arc section 1 and the second main arc section 4 are arranged along the circumferential direction and can be clamped on two sides of a workpiece.

One adjacent end of the first main arc section 1 and the second main arc section 4 are hinged or detachably connected, and the other adjacent end is detachably connected. In this way, at least one adjacent end of the first main arc section 1 and the second main arc section 4 are detachably connected, and the other adjacent end can be hinged or detachably connected, so that at least one openable opening between the first main arc section 1 and the second main arc section 4 can be ensured, and the workpiece can be clamped conveniently.

Two slewing lifting mechanisms 8 are oppositely connected to two sides of the enclasping mechanism, for example, one slewing lifting mechanism 8 is connected to the first main arc section 1, the other slewing lifting mechanism 8 is connected to the second main arc section 4, or the two slewing lifting mechanisms 8 are simultaneously connected to the first main arc section 1 or the second main arc section 4. It should be noted that the two slewing lifting mechanisms 8 need to be disposed opposite to each other, and therefore, when the two slewing lifting mechanisms 8 are simultaneously connected to the first main arc section 1 or the second main arc section 4, the corresponding first main arc section 1 or the second main arc section 4 needs to be in a major arc shape larger than a semicircle.

The lifting lug 9 may be attached to the clasping mechanism at a location different from the swivel hoist 8 by means of attachment means including, but not limited to, welding, adhesive, bolting, etc.

After the first main arc section 1 and the second main arc section 4 of the enclasping mechanism clamp the workpiece, the two rotary hoisting mechanisms 8 are connected through the two lifting hooks, and the lifting hooks are lifted to lift the workpiece, so that the workpiece is in a reversible state. Then, a traveling crane such as a traveling crane is connected with the lifting lug 9, and the traveling crane is caused to travel to drag the lifting lug 9 according to the turnover requirement, so that a workpiece is dragged to turn over by taking the connecting line of the two rotary lifting mechanisms 8 as a rotating shaft. After the workpiece is clamped by the enclasping mechanism, two rotary hoisting mechanisms 8 which are oppositely arranged at two sides of the enclasping mechanism are used as turning centers, and the lifting lug 9 is dragged by mechanical travelling equipment such as a travelling crane, so that the workpiece is turned over relative to the connecting line of the two rotary hoisting mechanisms 8, and the turning operation does not need manual supporting and force application any more, so that the potential safety hazard to operators is eliminated. And because all use mechanical equipment to carry out the upset operation, its efficiency improves greatly than manual upset.

As an alternative embodiment, as shown in fig. 4, the swing hoisting mechanism 8 includes an ear mount 81 and a swing suspension post 82. The ear mount 81 is attached to the clasping mechanism by means of a connection including, but not limited to, welding, adhesive, bolting, etc., such as to the first main arc segment 1 or the second main arc segment 4. The rotary hanging column 82 is connected to the ear seat 81 by a connection mode including but not limited to welding, bonding, bolting, etc., and the rotary hanging column 82 is provided with a circumferential groove which is convenient for embedding a lifting hook, and the lifting hook can freely rotate in the circumferential groove.

In order to make the manufacturing and the use of the enclasping mechanism more flexible, as shown in fig. 1-3, the enclasping mechanism according to the embodiment of the present utility model further includes a first auxiliary arc section 2 and a second auxiliary arc section 3. The first auxiliary arc section 2 and the second auxiliary arc section 3 are respectively connected between two adjacent ends of the first main arc section 1 and the second main arc section 4. For example, the first secondary arc 2 is disposed between one adjacent end of the first and second primary arcs 1, 4, and the second secondary arc 3 is disposed between the other adjacent end of the first and second primary arcs 1, 4. Therefore, the enclasping mechanism is composed of four arc sections which are connected in sequence, the manufacturing of the enclasping mechanism can be processed in a modular and sectional mode, and the size of each processing module is smaller, so that the processing is facilitated. When the arc-shaped section assembling device is used, a plurality of people can assemble all arc-shaped sections simultaneously, so that the assembling efficiency is higher and the assembling is more flexible.

As an alternative embodiment, as shown in fig. 2, one end of the first auxiliary arc section 2 is connected with one end of the first main arc section 1 through a hinged connection mechanism 6, and the other end of the first auxiliary arc section 2 is connected with one end of the second main arc section 4 through a detachable locking connection mechanism 7. One end of the second auxiliary arc section 3 is connected with the other end of the first main arc section 1 through another hinged connection mechanism 6, and the other end of the second auxiliary arc section 3 is connected with the other end of the second main arc section 4 through another detachable locking connection mechanism 7.

Wherein, as shown in fig. 6, the hinge connection mechanism 6 may include a rotation pin 61, a rotation support 62, and a latch 63. The pivot pin 61 is connected to the end of the first main segment 1. The swivel support 62 is connected to the end of the first secondary segment 2 or the second secondary segment 3. The latch 63 passes through both the rotation pin 61 and the rotation support 62, thereby enabling the rotation pin 61 and the rotation support 62 to rotate relatively.

A through hole may be formed in the distal end of the latch 63 in the radial direction and a locking pin 64 may be inserted to prevent the latch 63 from being removed during rotation.

Fig. 7 shows a schematic structural diagram of the connection between the second secondary arc section 3 and the second primary arc section 4 via a detachable locking connection 7, which is taken as an example to explain the specific structure of the detachable locking connection 7. The detachable locking connection 7 may include a rotation post 71, an extension plate 72, a limit seat 75, a locking adjuster 76, a hanging ring 710, and a hook 711.

One end of the extension plate 72 may be connected to the end of the first secondary arc segment 2 or the second secondary arc segment 3 by a connection means including, but not limited to, welding, adhesive, bolting, etc., and the other end of the extension plate 72 extends out toward the end of the second primary arc segment 4.

One end of the rotation post 71 is rotatably connected to the extension plate 72, and for example, a rotation pin seat 77 may be mounted on the extension plate 72 by a connection means including, but not limited to, welding, bonding, bolting, etc., and the rotation post 71 may be freely rotated with respect to the rotation pin seat 77 by a rotation pin 78 passing through both the rotation post 71 and the rotation pin seat 77. A through hole may be formed at the end of the rotation pin 78 and a locking pin 79 may be inserted to prevent the rotation pin 78 from being removed.

The limiting seat 75 is slidably sleeved on the rotating post 71. The locking adjustment member 76 is adjustably connected to the rotating post 71 and is located on a side of the limiting seat 75 adjacent to the second main arc section 4, for example, an external thread is formed on the rotating post 71, and a matching internal thread is formed on the locking adjustment member 76.

The hook 711 is connected to the end of the second main arc section 4. One end of the hanging ring 710 is fixedly connected or hinged with the limiting seat 75, and the other end is used for being hung with the hanging hook 711.

The rotating post 71 is rotated to allow the hanging ring 710 and the hanging hook 711 to be hung or unhooked, thereby allowing the second sub-arc 3 and the second main arc 4 to be connected together or separated, so as to facilitate the mounting and clamping or dismounting of the clasping mechanism to the workpiece. The position of the limiting seat 75 on the rotating column 71 can be adjusted by adjusting the position of the locking adjusting piece 76 on the rotating column 71, so that the distance between the hanging ring 710 and the hanging hook 711 and the clamping force can be adjusted, and the clasping mechanism can adapt to different sizes and adjust different clamping forces.

In order to prevent the suspension link 710 and the hook 711 from being separated accidentally due to the accidental rotation of the rotating post 71, the embodiment of the present utility model may also consider that a supporting seat 73 is mounted on the extension plate 72 by a connection method including, but not limited to, welding, bonding, bolting, etc., and the rotating post 71 is positioned in the supporting seat 73 after rotating in place, and then a locking pin 74 is inserted into the supporting seat 73 to prevent the rotating post 71 from rotating randomly.

The first auxiliary arc section 2 and the second auxiliary arc section 3 can also be respectively used as installation bases of the two rotary hoisting mechanisms 8, and the lifting lug 9 can be installed on the first main arc section 1 as shown in fig. 4, so that the stress of the whole enclasping mechanism is more uniform.

Because the shell sections and the short shell bodies are smoother, the short shell bodies are bound by the hanging belt, and the hanging belt is free from any anti-skid device, so that the hanging belt can easily slide along the direction of the shell bodies, and even the shell bodies fall off in the overturning process, thereby causing serious consequences. In order to prevent the workpiece from sliding during lifting, as shown in fig. 1-3, an embodiment of the present utility model may further include an anti-slip pull rod 10. The two anti-slip pull rods 10 are connected to the enclasping mechanism and are perpendicular to the plane where the enclasping mechanism is located, and the two anti-slip pull rods 10 face different directions, and can hook the two ends of a workpiece to prevent the workpiece from sliding out of the enclasping mechanism.

As shown in fig. 8, the anti-slip drawbar 10 may include a base 101, a drawbar 102, and a drawbar 103. The base 101 may be attached to the clasping mechanism by means of a connection including, but not limited to, welding, adhesive, bolting, etc., such as to the first secondary arc 2/second secondary arc 3. One end of the pull rod 102 is detachably connected to the base 101, and the other end is connected to the drag hook 103. The drag hook 103 is used for hooking the end of the workpiece.

In some embodiments, the anti-skid drawbar 10 may further include a stop collar 104 and a lock 105. The base 101 may be provided with a through hole or a groove for the pull rod 102 to pass through. The limiting ring 104 is arranged on the pull rod 102. After the pull rod 102 passes through the through hole or the groove, the limiting ring 104 is abutted against one side of the through hole or the groove, and the locking piece 105 is detachably connected to the pull rod 102 and abutted against the other side of the through hole or the groove. For example, external threads may be machined on the pull rod 102 and mating internal threads may be machined on the lock 105. In this way, the pull rod 102 with different lengths can be replaced according to the length of the workpiece, so that better pulling force can be provided for the workpiece.

The two anti-slip tie rods 10 can be respectively mounted on the first auxiliary arc section 2 and the second auxiliary arc section 3, and can also be respectively mounted on the first main arc section 1 and the second main arc section 4.

As described above, since the shell section and the short shell cylinder are relatively smooth, and because the shell section and the short shell cylinder require a relatively high surface flatness, in order to avoid the clasping mechanism from scratching the surface of the workpiece, the embodiment of the present utility model may further add a layer of protection strip 51 on the inner side of the clasping mechanism by means including, but not limited to, bonding, etc., where the protection strip 51 may be made of rubber, resin or flexible metal (such as copper), etc. The protective strip 51 can also increase the contact area between the clasping mechanism and the workpiece, reduce the stress of the unit area of the surface of the workpiece, and play a certain role in skid resistance.

In order to maintain the protection bar 51 in a good shape, a plurality of ribs 52 may be added uniformly at intervals between the protection bar 51 and the clasping mechanism.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above-described preferred embodiments should not be construed as limiting the utility model, which is defined in the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
