Description

Technical Field

[0001] The utility model belongs to the field of pressure vessel manufacturing, in particular to a connection assembly for turning over a large cylinder section. Background Art

[0002] During the pressure vessel manufacturing process, it is necessary to flip the cylindrical parts, which are also called cylinder sections.

[0003] In the existing operating process, the wire rope is manually wound onto the drum segment and then flipped. Because the drum segment is heavy, mostly 30 tons to 40 tons, and the end face of the formed drum segment is relatively sharp, if it is flipped only by the wire rope, the sharp end face will cut the wire rope during the flipping process, causing it to break. The heavy drum segment will accelerate the breakage time, posing a safety hazard at the construction site. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a connection assembly for flipping large cylinder segments, which can make the flipping of the cylinder segment orderly and safely carried out through the coordinated linkage of the main hook body and the auxiliary hook body, thereby ensuring the safety of on-site construction and saving the operator's time in winding the wire rope around the cylinder segment.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a connecting assembly for turning over a large barrel section, comprising a main hook body and an auxiliary hook body;

[0006] The main hook body is used to be inserted into one end of the cylinder wall, and its end extends from the inner cavity of the cylinder segment to bear the weight of the cylinder segment. The front and rear sides of the main hook body can respectively allow the wire rope to pass through;

[0007] The auxiliary hook body is inserted into the other end of the cylinder wall on the same side as the main hook body, and the end of the auxiliary hook body can be passed through by the wire rope to drive the cylinder section to flip;

[0008] The main hook body and the auxiliary hook body are arranged opposite to each other so that the cylinder section is evenly stressed.

[0009] Furthermore, the end of the main hook body extends upward to form a lifting portion, and an upper clamping groove is provided on the inner side of the lifting portion.

[0010] Furthermore, a lower clamping groove is provided on the inner side of the auxiliary hook body.

[0011] Furthermore, the width of the upper clamping groove and the width of the lower clamping groove both match the thickness of the cylinder wall.

[0012] Furthermore, an auxiliary hole is provided on the lifting portion, and the auxiliary hole is located on the outside of the cylinder section and is used for the passage and release of the wire rope.

[0013] Furthermore, an auxiliary groove for laying out a steel wire rope is provided at the lower end portion of the main hook body. The auxiliary groove is located outside the barrel section and is used for the passage and release of the steel wire rope.

[0014] Furthermore, an upper hanging hole is provided on the other end of the main hook body opposite to the auxiliary hole for the passage of the wire rope.

[0015] Furthermore, a flip hole is provided at the end of the auxiliary hook body. The flip hole is located at the lower end of the lower clamping groove and is used to allow the wire rope to pass through and be located outside the cylinder segment.

[0016] The advantages and positive effects of the utility model are:

[0017] 1. Due to the adoption of the above technical solution, through the coordinated linkage of the main hook body and the auxiliary hook body, the operator does not need to wrap the wire rope around the drum segment. It is only necessary to hang the main hook body and the auxiliary hook body on the same side of the drum wall. Compared with the traditional lifting method, the drum segment flipping process is simplified, and the drum segment flipping work can be carried out in an orderly and safe manner.

[0018] 2. The main hook is long enough to pass through the inner cavity of the cylinder. By lifting the main hook at two points, the main hook can bear the weight of the cylinder to prevent the cylinder from falling off. By pulling the wire rope on the auxiliary hook upwards, the cylinder can be turned over.

[0019] The arrangement of the upper clamping slot in the main hook body and the lower clamping slot in the auxiliary hook body can steadily lift the cylinder section after flipping, so that the cylinder section can fall steadily and avoid collision.

[0020] 3. The utility model has a simple and compact structure, low processing costs for the main hook body and the auxiliary hook body, and is easy to install, making it easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1 to 4 As shown, this embodiment provides a connection assembly for turning over a large barrel section, comprising a main hook body 1 and an auxiliary hook body 2;

[0031] The main hook body 1 is used to be inserted into one end of the cylinder wall. The end of the main hook body 1 extends outward, and its length extends from the inner cavity of the cylinder segment to bear the weight when the cylinder segment is lifted. The front and rear sides of the main hook body 1 are respectively provided for the wire rope to pass through;

[0032] A lifting portion 11 is formed at the end of the main hook body 1, extending upward, so that the main hook body 1 is "L"-shaped. An upper clamping groove 111 is provided on the inner side of the lifting portion 11 for engaging with the cylinder wall.

[0033] In order to allow the steel wire rope to pass through the front and rear sides of the main hook body 1, in this embodiment, an auxiliary hole 112 for connecting and releasing the steel wire rope is provided on the lifting portion 11. The steel wire rope can be disconnected from the auxiliary hole 112 when the barrel section is flipped. An upper hoisting hole 13 for passing the steel wire rope is provided at the other end of the main hook body 1;

[0034] In another embodiment, an auxiliary groove 12 for laying a wire rope is provided at the lower end of the main hook body 1, which is used for connecting and releasing the wire rope. The auxiliary groove 12 is located on the outside of the barrel section, and an upper lifting hole 13 for passing the wire rope is provided at the other end of the main hook body 1.

[0035] The auxiliary hook body 2 is inserted into the other end of the cylinder wall on the same side as the main hook body 1, and the end of the auxiliary hook body 2 can be used for the wire rope to pass through;

[0036] A lower clamping groove 21 is provided on the inner side of the auxiliary hook body 2, making the auxiliary hook body 2 "C"-shaped. To prevent the cylinder segment from shaking during lifting, the width of the upper clamping groove 111 and the width of the lower clamping groove 21 are matched with the wall thickness of the cylinder.

[0037] A turning hole 22 for the steel wire rope to pass through is provided at the end of the auxiliary hook body 2. The turning hole 22 is located at the lower end of the lower clamping groove 21 so that the steel wire rope is located outside the barrel section.

[0038] The main hook body 1 and the auxiliary hook body 2 are arranged relative to each other so that the cylinder section is evenly stressed.

[0039] The working process of this example:

[0040] The main hook body 1 and the auxiliary hook body 2 are respectively inserted into the same side of the cylinder wall through the upper clamping groove 111 and the lower clamping groove 21, and are arranged opposite to each other, so that the two steel ropes pass through the auxiliary hole 112 and the upper lifting hole 13 respectively. At this time, the main hook body 1 bears the weight of the cylinder segment, so that the other steel rope passes through the flipping hole 22. The cylinder segment begins to flip by pulling the steel rope in the flipping hole 22. At this time, the connection of the steel rope at the auxiliary hole 112 is released, so that the steel rope in the upper lifting hole 13 and the steel rope in the flipping hole 22 are parallel, completing the flipping of the cylinder segment. The upper clamping groove 111 and the lower clamping groove 21 lift the same end of the cylinder segment, so that the flipped cylinder segment lands smoothly.

[0041] While one or more embodiments of the present invention have been described in detail above, the foregoing descriptions are merely preferred embodiments of the present invention and should not be construed as limiting the scope of implementation of the present invention. Any equivalent variations and improvements made within the scope of the present invention shall still fall within the scope of the patent application of the present invention.
