Description

Technical Field

[0001] The utility model belongs to the technical field of marine engineering hoisting, and in particular relates to a sea pipe inverted hoisting positioning device. Background Art

[0002] At present, the outer part of the sea pipes used in marine engineering is wrapped with cement coating. The traditional way of lifting sea pipes is usually to directly use steel wire buckles or protected steel wire buckles for lifting. However, in actual operation, marine engineering ships usually lay sea pipes on barges. The sea pipe transport barges have shallow draft and cannot be anchored. It is common for them to fluctuate up and down. When the sea conditions are poor, the two ships will fluctuate, causing the hook head of the sea pipe to shake during the barge operation. This can easily cause the displacement and falling off of the pipe end of the steel wire buckle, the hanging, and the cement coating squeezing the steel wire buckle. This increases the burden of the rigging worker to frequently arrange the hooks, which can easily cause safety hazards to the rigging worker, resulting in hand squeeze and pinch injuries. In addition, the steel wire buckle is easily damaged and broken, and the efficiency of sea pipe barge is low.

[0003] Therefore, it is urgent to design a subsea pipeline inversion lifting and positioning device to solve the above-mentioned problems that the rigging workers are prone to safety accidents and the wire buckles are easily damaged and broken. Utility Model Content

[0004] In order to solve the safety problem in the process of lifting the submarine pipeline mentioned in the background technology, a submarine pipeline lifting and positioning device is provided to solve the problem that the rigging workers are prone to safety accidents and the wire buckles are easily damaged and broken.

[0005] In order to achieve the above-mentioned purpose, the specific technical scheme of a subsea pipe inversion hoisting and positioning device of the utility model is as follows:

[0006] A subsea pipe reverse hoisting positioning device comprises a steel wire buckle for hoisting the subsea pipe, wherein the inner ring of the steel wire buckle is provided with a positioning steel ring, the positioning steel ring can be sleeved on the end of the subsea pipe, and a first separation gap is provided between the positioning steel ring and the subsea pipe;

[0007] The positioning steel ring has a stressed state and a relaxed state.

[0008] When the positioning steel ring is under stress, the steel wire buckle lifts the sea pipe, and the positioning steel ring tilts along with the steel wire buckle. The positioning steel ring is squeezed by the gravity of the sea pipe and abuts against the sea pipe to fix the steel wire buckle;

[0009] When the positioning steel ring is in a relaxed state, the positioning steel ring is separated from the sea pipe through the first disengagement gap.

[0010] Furthermore, when the positioning steel ring is in a stressed state, the bottom and the top of the positioning steel ring are both in contact with the sea pipe, so that friction is generated between the positioning steel ring and the sea pipe.

[0011] Furthermore, when the positioning steel ring is in a relaxed state, the inner ring diameter of the positioning steel ring is smaller than the diameter of the cement coating.

[0012] Further, the positioning steel ring is wrapped with the elastic rubber layer.

[0013] Furthermore, the inner diameter of the elastic rubber layer is larger than the diameter of the sea pipe.

[0014] Further, the inner circle diameter of the elastic rubber layer is smaller than the diameter of the cement coating.

[0015] Furthermore, the positioning steel ring and the steel wire buckle are fixed by a steel cable tie.

[0016] Furthermore, a plurality of steel cable ties are arranged along the circumference of the positioning steel ring.

[0017] Furthermore, adjacent steel cable ties are arranged at equal distances.

[0018] Furthermore, one end of the wire buckle away from the positioning steel ring is connected with a lifting ring.

[0019] The utility model of the subsea pipe inversion hoisting positioning device has the following advantages:

[0020] The utility model can accurately fix the wire buckle, can reduce the number of times the rigger arranges the hook, shortens the operation time, effectively reduces the risk factors in the operation, thereby improving the operation safety and effectively improving the operation efficiency.

[0021] The utility model is simple to operate and convenient to maintain, can be applicable to the hoisting of cement-coated sea pipes of any pipe diameter, and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0027] Please refer to the attached Figure 1 To Attachment Figure 2 The utility model describes a subsea pipe inverting, lifting and positioning device.

[0028] During maritime transportation, the hull rises and falls greatly, causing the hook head of the sea pipe to shake during the barge operation, which can easily cause the pipe wire buckle to shift and fall off at the pipe end, get caught, and the cement coating to squeeze the wire buckle.

[0029] Therefore, if Figure 1 and Figure 2 As shown, a subsea pipe inverting hoisting positioning device of the utility model comprises a steel wire buckle 1 for hoisting a subsea pipe 3, the inner ring of the steel wire buckle 1 is provided with a positioning steel ring 2, the positioning steel ring 2 can be sleeved on the end of the subsea pipe 3, and a first separation gap is provided between the positioning steel ring 2 and the subsea pipe 3;

[0030] The positioning steel ring 2 is provided with a stressed state and a relaxed state.

[0031] When the positioning steel ring 2 is under stress, the steel wire buckle 1 lifts the sea pipe 3, and the positioning steel ring 2 tilts along with the steel wire buckle 1. The positioning steel ring 2 is squeezed by the gravity of the sea pipe 3 and abuts against the sea pipe 3 to fix the positioning steel ring 2. The abutment between the positioning steel ring 2 and the sea pipe 3 generates friction force to prevent the buckle from falling off, so as to position the steel wire buckle 1.

[0032] When the positioning steel ring 2 is in a relaxed state, the positioning steel ring 2 is separated from the sea pipe 3 through the first disengagement gap.

[0033] When the positioning steel ring 2 is in a stressed state, the bottom and the top of the positioning steel ring 2 are both in contact with the sea pipe 3, so that friction is generated between the positioning steel ring 2 and the sea pipe 3. At this time, the bottom and the top of the positioning steel ring 2 are the positions where the friction is the largest, and the positioning steel ring 2 and the sea pipe 3 are fixed by at least two stressed positions; if the positioning steel ring 2 is deformed by force, the shape becomes an ellipse, that is, the positioning steel ring 2 is completely in contact with the sea pipe 3, and the first separation gap disappears. At this time, the friction between the positioning steel ring 2 and the sea pipe 3 is the largest, and the positioning effect is the best.

[0034] When the positioning steel ring 2 is in a relaxed state, the inner ring diameter of the positioning steel ring 2 is smaller than the diameter of the cement coating 4 , so that the positioning steel ring 2 is restricted from moving toward the center of the sea pipe 3 by the end surface of the cement coating 4 .

[0035] The positioning steel ring 2 is made of high-strength material and is circular in shape, preferably a steel ring. Meanwhile, other high-strength materials well known to those skilled in the art, such as iron, copper, etc., may also be used.

[0036] Preferably, in order to improve the positioning effect of the positioning steel ring 2, an elastic rubber layer is wrapped around the outside of the positioning steel ring 2 to increase the friction between the positioning steel ring 2 and the sea pipe 3. The inner ring diameter of the elastic rubber layer is larger than the diameter of the sea pipe 3, so that the positioning steel ring 2 can be sleeved on the end of the sea pipe 3. The inner ring diameter of the elastic rubber layer is smaller than the diameter of the cement coating 4, so that the end surface of the cement coating 4 limits the positioning steel ring 2 to prevent the positioning steel ring 2 from moving toward the center of the sea pipe 3.

[0037] like Figure 2 As shown, the positioning steel ring 2 and the steel wire buckle 1 are fixed by a steel cable tie 5.

[0038] Preferably, a plurality of steel cable ties 5 are provided along the circumference of the positioning steel ring 2 to ensure that the positioning steel ring 2 is securely connected to the wire buckle 1 .

[0039] Preferably, adjacent steel cable ties are arranged at equal distances to further ensure the reliability of the connection between the positioning steel ring 2 and the steel wire buckle 1.

[0040] Optionally, in order to improve the practicality and versatility of the utility model, the positioning steel ring 2 can also be made by bending the steel wire into a circle, and then using steel tie ties 5 to tie and fix the two ends of the steel wire.

[0041] One end of the wire buckle 1 away from the positioning steel ring 2 is connected with a lifting ring 6, and the wire buckle 1 is connected to the crane through the lifting ring 6.

[0042] The utility model can accurately fix the wire buckle 1, can reduce the number of times the rigger arranges the hook, shortens the operation time, effectively reduces the risk factors in the operation, thereby improving the operation safety, effectively improves the operation efficiency, and is simple to operate and easy to maintain. It can be applied to the lifting of cement coated submarine pipes of any diameter and has broad application prospects.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
