Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a large-diameter thin-plate cylinder anti-deformation tool. Background Art

[0002] In recent years, the country has increased its support for offshore wind power projects, and my country's wind power industry is in a stage of vigorous development. With the increasing maturity of technology, a new type of offshore wind power has emerged - the suction tube type conductor frame. The suction tube application technology has the characteristics of convenient installation, short cycle, convenient dismantling, no noise, and no piling vibration during offshore construction. It effectively reduces the pollution of engineering construction to the marine environment and protects the ecological environment. The suction tube type conductor frame has gradually become the development trend of the offshore wind power market.

[0003] The suction tube conductor racks in Changle C area of ​​AVIC I, with a unit capacity of 10MW, are all suction tube type (three pile) conductor racks, and are the conductor racks with the largest installed capacity in my country. Figure 1 As shown in the figure, the suction tube, one of the important components of the conductor frame, has a diameter of 12,000 mm, a plate thickness of 35 to 50 mm, a length of 22,500 mm, and a single tube weight of about 410 tons. Unlike traditional wind power pipe piles, the suction tube has a large diameter and a thin wall. Due to the thin plate of the suction tube and the deflection due to its own weight, plastic deformation of the tube is easy to occur during the manufacturing process, especially the stress at the roller frame position, which is the stress point of the tube, is prone to exceed the standard, and there is a risk of plastic deformation or even rupture; in addition, the suction tube has a total of 8 single circles, and due to the deflection of the tube, the roundness does not meet the design requirements. Therefore, during the structural assembly process, the suction tube structure is not strong enough, and the uneven force leads to excessive stress, which cannot meet the assembly conditions, and subsequent lifting, transportation, turning over and other processes cannot be achieved. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems in the background technology and to provide an anti-deformation tooling which can prevent the suction cylinder from being deformed and make the roundness of the suction cylinder meet the design requirements.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model adopts a technical solution specifically as follows: a large-diameter thin-plate cylinder anti-deformation tooling, including a lateral stop support assembly and an internal support assembly;

[0006] The lateral blocking support assemblies are arranged in pairs and are respectively located on both sides of the suction cylinder. The lateral blocking support assemblies include a blocking support base, a roller blocking support and a connecting rod. One end of the roller blocking support is hinged to the upper side of the blocking support base, one end of the connecting rod is hinged to the upper side of the blocking support base, and the other end of the connecting rod is hinged to the side wall of the roller blocking support. The blocking support base, the roller blocking support and the connecting rod together form a triangular structure.

[0007] The internal support assembly is arranged inside the suction cylinder, and the internal support assembly includes an inner ring plate and a cross brace arranged inside the inner ring plate. The internal support assembly can strengthen the strength of the suction cylinder to resist external stress and avoid the downward deflection of the cylinder body. Therefore, the roundness requirements of the suction cylinder can be guaranteed, and the manufacturing accuracy can be further guaranteed.

[0008] Furthermore, the stop support base, the roller stop support and the connecting rod together form a triangular structure, and the triangular structure is more stable and has a good supporting effect.

[0009] Furthermore, the support base and the roller frame base are fixedly connected together to form a common base.

[0010] Furthermore, a detachable connecting seat 1 and a connecting seat 2 are provided on the upper side of the blocking support base, and the connecting seat 1 and the roller blocking support, as well as the connecting seat 2 and the connecting rod are detachably connected via pins respectively. Pin holes are provided on the connecting seat 1 and the roller blocking support, and they are detachably connected together via pins; pin holes are also provided on the connecting seat 2 and the connecting rod, and they are also detachably connected together via pins. Such a detachable arrangement is convenient for storage, storage and transportation.

[0011] Furthermore, a plurality of mounting holes for mounting connecting seat one and connecting seat two are arranged on the upper side of the support base, and the plurality of mounting holes are arranged on a straight line connecting connecting seat one and connecting seat two. In this way, by using different mounting holes, the mounting position of connecting seat one or connecting seat two can be changed, thereby changing the inclination angle of the roller support to adapt to suction cylinders of different diameters.

[0012] Furthermore, a detachable connecting seat three is arranged on one side of the roller stop close to the connecting rod, and the connecting seat three is detachably connected to the connecting rod via a pin shaft, so that disassembly and assembly are convenient.

[0013] Furthermore, the roller stop is longitudinally provided with a plurality of fixing holes for installing the connection seat three. The connection seat three can change the inclination angle of the roller stop by being installed in different fixing holes, thereby being able to adapt to suction cylinders of different diameters.

[0014] Furthermore, a supporting roller is arranged on one side of the roller support away from the connecting seat. By setting the supporting roller, the number of stress points and the stress area are increased compared with the traditional support only by the roller frame, thereby reducing the stress of each stress point and avoiding plastic deformation of the cylinder.

[0015] Furthermore, the Pozidriv brace is welded on the inner wall of the inner ring plate, and the Pozidriv brace supports the inner ring plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model arranges lateral support assemblies on both sides of the roller frame. The lateral support assemblies can provide support for both sides of the suction cylinder to increase the number of force points and the force area of ​​the suction cylinder and reduce the stress at each force point, thereby preventing the cylinder from bending downward and excessive local stress from causing plastic deformation of the cylinder. At the same time, since the number of force points on both sides of the suction cylinder is increased, the stability of the suction cylinder placement can also be improved, which is beneficial to reducing safety hazards during the processing process.

[0018] 2. The inclination angle of the roller guard in the lateral guard assembly can be adjusted. The connecting seat 1 and the connecting seat and are installed on different mounting holes to change the inclination angle of the roller guard. At the same time, the connecting seat 3 can also be installed on different fixing holes to change the inclination angle of the roller guard. The change in the inclination angle of the roller guard can adapt to suction cylinders of different diameters, thereby making the device more applicable.

[0019] 3. The utility model also provides an internal support assembly, which is placed inside the suction cylinder. This can strengthen the structural strength of the suction cylinder to resist external stress and avoid the downward deflection of the suction cylinder body. At the same time, it can also ensure the design requirements of the roundness of the suction cylinder, which is conducive to improving processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] Example: Figure 2-Figure 8 As shown, this embodiment provides a large-diameter thin-plate cylinder anti-deformation tool, including a lateral stopper assembly 1 and an internal support assembly 2;

[0032] The lateral blocking support assembly 1 is arranged in pairs and is respectively located on both sides of the suction cylinder 3. The lateral blocking support assembly 1 includes a blocking support base 4, a roller blocking support 5 and a connecting rod 6. One end of the roller blocking support 5 is hinged to the upper side of the blocking support base 4, one end of the connecting rod 6 is hinged to the upper side of the blocking support base 4, and the other end of the connecting rod 6 is hinged to the side wall of the roller blocking support 5; the blocking support base 4, the roller blocking support 5 and the connecting rod 6 together form a triangular structure, which is more stable and has a good supporting effect. The blocking support base 4 is fixedly connected to the roller frame base 9 to form a common base.

[0033] A detachable connecting seat 10 and a connecting seat 2 11 are provided on the upper side of the retaining support base 4. The connecting seat 10 and the roller retaining support 5, as well as the connecting seat 2 11 and the connecting rod 6 are detachably connected via pins. Pin holes are provided on the connecting seat 10 and the roller retaining support 5, and they are detachably connected together via pins; pin holes are also provided on the connecting seat 2 11 and the connecting rod 6, and they are also detachably connected together via pins. Such a detachable connection arrangement is convenient for the storage, storage and transportation of the anti-deformation tooling; a plurality of mounting holes for installing the connecting seat 10 and the connecting seat 2 11 are provided on the upper side of the retaining support base 4, and the plurality of mounting holes are provided on the straight line connecting the connecting seat 10 and the connecting seat 2 11, so that the connecting seat 10 or the connecting seat 2 11 can change the installation position of the connecting seat 10 or the connecting seat 2 11 by using different mounting holes, thereby changing the roller retaining support 5's inclination angle can be adjusted to adapt to suction cylinders 3 of different diameters; a detachable connecting seat three 12 is provided on the roller stop support 5 near the connecting rod 6, and the connecting seat three 12 is detachably connected to the connecting rod 6 through a pin shaft, which is convenient for disassembly and assembly; a plurality of fixing holes for installing the connecting seat three 12 are longitudinally arranged on the roller stop support 5, and the connecting seat three 12 can change the inclination angle of the roller stop support 5 by being installed on different fixing holes, so that it can also adapt to suction cylinders 3 of different diameters, thereby enhancing the applicability of the anti-deformation tooling; a supporting roller 13 is provided on the roller stop support 5 away from the connecting seat three 12, and the suction cylinder 3 is supported by the supporting roller 13. By providing the supporting roller 13, compared with the traditional support only by the roller frame 14, the number and area of ​​the force points of the suction cylinder 3 are increased, thereby reducing the stress borne by each force point, thereby avoiding plastic deformation of the cylinder body.

[0034] The internal support assembly 2 is arranged inside the suction cylinder 3. The internal support assembly 2 includes an inner ring plate 7 and a cross-shaped strut 8 arranged inside the inner ring plate 7. The internal support assembly 2 can strengthen the structural strength of the suction cylinder 3 to resist external stress and avoid the downward deflection of the cylinder body. At the same time, it can also ensure the roundness requirements of the suction cylinder 3 and further ensure the processing accuracy; the cross-shaped strut 8 is welded on the inner wall of the inner ring plate 7, and the cross-shaped strut 8 supports the inner ring plate 7.

[0035] The suction cylinder 3 has a total of eight single-circle small segments. Due to the downward deflection of the cylinder, the roundness does not meet the design requirements. Through finite element calculation, it is found that during the assembly process, the structural strength of the suction cylinder 3 is insufficient, and the uneven force leads to excessive stress, which cannot meet the assembly conditions. Therefore, the structural strength of the cylinder can be significantly improved by optimizing the assembly process and installing anti-deformation tooling inside the cylinder. For example, when making a single-circle small stage, the first segment of the suction cylinder is hoisted and turned over to the horizontal tire frame, and a circle of inner ring plates 7 are installed on the inner wall. The structural form is T-row, and finally the M-shaped support 8 is welded and fixed to the inner ring plate 7, such as Figure 6, ensuring the roundness of the first section of the suction cylinder; then the second section of the suction cylinder is turned over and hoisted to the work station, and is welded vertically with the first section of the suction cylinder on the horizontal tire frame based on the four-equal division line preset during installation. Figure 7 After welding is completed, turn it over and hoist it to the assembly station, and then assemble it with the remaining suction cylinder single circle. Figure 8 After the internal support tooling was installed on the first segment of the suction cylinder, the manufacturing accuracy was guaranteed and it became the "leader" to ensure that the remaining single-circle segments were manufactured in matching fashion with it. After the internal support tooling was installed on the suction cylinder 3, the structural strength was significantly enhanced, and the stress results at the roller frame position were better, meeting the manufacturing requirements.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
