TECHNICAL FIELD

[0001] The application relates to the field of pipeline hoisting technology, in particular to a protective pad for pipeline hoisting. BACKGROUND

[0002] In the pipeline hoisting operation, ropes are usually used to hoist and move the pipeline. However, when the ropes directly contact the surface of the pipeline, the surface of the pipeline is prone to be abraded or indented, especially when heavy pipelines are hoisted, the local pressure of the ropes is large, which may cause damage to the surface of the pipeline. In addition, in the traditional hoisting mode, the friction between the ropes and the pipeline is insufficient, which is prone to cause the pipeline to slide or fall off during hoisting, and safety hazards exist. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0028] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

[0029] The embodiment of the present application discloses a protection pad for hoisting a pipeline. As shown in Figure 1 andFigure 2 The pipe hoisting protection pad comprises a sheath 11, a pressing plate 12, an adjusting assembly 2 and an anti-skid pad 4.

[0030] As Figure 3 and Figure 4 The sheath 11 is made of wear-resistant and corrosion-resistant material and has an arc shape. The sheath 11 is provided in a plurality of sets and is sleeved on the rope 1 used for hoisting the pipe. The inner wall of the sheath 11 is tightly combined with the rope 1 to prevent the rope 1 from sliding or wearing the surface of the pipe during hoisting.

[0031] The pressing plate 12 is movably arranged on the outer wall of the sheath 11. The number of the pressing plate 12 is set according to actual requirements. In the embodiment, the pressing plate 12 is hinged to the sheath 11, and the sheath 11 is provided with a plurality of sets. Each set of the pressing plate 12 is provided with two pressing plates 12, and the two pressing plates 12 in the same set are oppositely arranged. Such a design can enable each set of the pressing plate 12 to clamp the rope 1 from both sides, thereby improving the stability of the rope 1.

[0032] As Figure 4 and Figure 5 The adjusting assembly 2 is arranged between the two pressing plates 12 in the same set and is used for controlling the overturning of the pressing plate 12 and adjusting the clamping degree of the pressing plate 12 on the rope 1. Specifically, the adjusting assembly 2 comprises a screw sleeve 21 hinged to one of the pressing plates 12 and a sleeve 22 hinged to the other pressing plate 12. A locking bolt 23 is arranged in the sleeve 22, and the threaded portion of the locking bolt 23 is threadedly connected with the screw sleeve 21. By rotating the locking bolt 23, the relative movement between the screw sleeve 21 and the locking bolt 23 can be generated, thereby driving the two pressing plates 12 to move close to or away from each other, so as to clamp or loosen the rope 1.

[0033] One end of the locking bolt 23 is coaxially and integrally formed with a limiting column 24, the diameter of the limiting column 24 is greater than the maximum diameter of the locking bolt 23, and the inner diameter of the sleeve 22 is greater than or equal to the diameter of the limiting column 24. Meanwhile, a through groove 25 for the locking bolt 23 to pass through is formed on the sleeve 22, and the groove width of the through groove 25 is less than the diameter of the limiting column 24. The locking bolt 23 is threadedly connected with the screw sleeve 21. The operator overturns the locking bolt 23, so that the locking bolt 23 extends into the sleeve 22 from the through groove 25. The operator tightens the locking bolt 23, so that the limiting column 24 can extend into the sleeve 22, thereby preventing the locking bolt 23 from being separated from the sleeve 22. In addition, a baffle 26 is arranged on the limiting column 24. The operator tightens the locking bolt 23, so that the baffle 26 abuts against the sleeve 22, thereby driving the corresponding two pressing plates 12 to overturn towards each other. The pressing plate 12 is pressed against the sheath 11, thereby realizing the connection between the rope 1 and the sheath 11.

[0034] The pressing plate 12 is provided with a pressing block 3 for pressing the rope 1 against the sheath 11. The pressing block 3 is wedge-shaped, and the inclined surface thereof is in contact with the rope 1, so as to increase the friction between the pressing block 3 and the rope 1. In order to further increase the friction, the inclined surface of the pressing block 3 is provided with sawtooth-shaped protrusions 31 in the embodiment. The pressing block 3 can more firmly hold the rope 1, so as to prevent the rope 1 from sliding during hoisting.

[0035] The anti-skid pad 4 is arranged on the outer wall of the sheath 11, and is used for directly abutting against the pipeline, so as to play a buffering and protecting role. The shape and size of the anti-skid pad 4 can be set according to actual requirements. In order to facilitate the operator to replace the anti-skid pad 4, the bottom of the anti-skid pad 4 is provided with a sliding block 41, and the outer wall of the sheath 11 is provided with a sliding groove 42 matched with the sliding block 41. By sliding the anti-skid pad 4, the anti-skid pad 4 can be conveniently assembled and disassembled on the sheath 11.

[0036] In addition, in order to further improve the stability of the anti-skid pad 4 and prevent it from sliding or falling off during hoisting, the pressing plate 12 is further provided with a clamping block 43, and the anti-skid pad 4 is provided with a clamping groove 44 for clamping the clamping block 43. When the pressing plate 12 is flipped and clamps the rope 1, the clamping block 43 is inserted into the clamping groove 44, so as to limit the sliding of the anti-skid pad 4.

[0037] When the protective pad for hoisting a pipeline is used, the sheath 11 is first sleeved on the rope 1 used for hoisting the pipeline, and the position of the anti-skid pad 4 is adjusted so as to tightly abut against the pipeline. Then, the pressing plate 12 is flipped and clamps the rope 1 by rotating the locking bolt 23. Finally, it is checked whether the clamping block 43 has been inserted into the clamping groove 44, so as to ensure the stability of the anti-skid pad 4. During hoisting, the protective pad can effectively prevent the rope 1 from directly contacting the pipeline to cause abrasion, so as to protect the surface of the pipeline from being damaged.

[0038] The above are preferred embodiments of the present application, and are not used to limit the protection scope of the present application. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
