Description

Technical Field

[0001] The present invention relates to the technical field of ship processing tools, and particularly to a pipe alignment deviation adjustment device. Background Art

[0002] Due to processing and transportation conditions, after the pipes arrive at the factory, they will undergo certain deformations, and there will be certain ovality deformations at their ends; there will be problems of long and short axes; in this case, there will be a certain amount of misalignment when the pipes are welded; it causes difficulties in welding alignment, and the welding adjustment situation is relatively large, affecting the welding quality of the pipes while also affecting the welding efficiency.

[0003] Under normal circumstances, the most common situation is that during the butt joint assembly of ship pipes, the butt joints of the pipes are fixed by manual spot welding or by using angle iron codes for spot welding. This not only causes harm to people's eyes due to the sparks generated by the welding iron during spot welding, but also damages the base material when spot welding or using angle codes for spot welding to fix the pipes, and increases the grinding work for removing the code plates or spot welding during welding. Especially when using stainless steel pipes, it will cause oxidation at the spot welding points of the stainless steel pipes, which is not conducive to the anti-corrosion requirements of the stainless steel pipes. At the same time, when performing the existing spot welding or code plate fixing work on the butt joints of pipes, a series of protective measures need to be taken for people. In short, in the existing process of pipe butt joint assembly, fixing the butt joints of pipes by spot welding or using angle iron codes for spot welding not only causes harm to people, but also damages the base material and increases the grinding work for removing the code plates and spot welding. Summary of the Invention

[0004] The technical problems to be solved by the present invention are: first, to solve the problems of large misalignment and difficult alignment caused by pipe deformation, and achieve high-precision butt joint and roundness deviation adjustment; second, to avoid damaging the base material by spot welding or code plate fixing, and reduce the removal and grinding work; third, to prevent sparks from hurting people, conform to ergonomics, and ensure operation safety and comfort; fourth, to improve the adaptability and economy of the device, which can be reused and is convenient for operation and storage.

[0005] To solve the above technical problems, the present invention provides a pipe alignment deviation adjustment device, which includes an adjustment assembly, a support seat, and a fixing device;

[0014] Compared with the prior art, the pipe alignment deviation adjusting device according to the embodiment of the present invention has the following beneficial effects:

[0015] (1) First, fix the second pipe, then sleeved the support base and the fixing device on the first pipe to be adjusted through a hollow coaxial structure, and adjust the position of the first pipe by using the adjusting component on the support base. At this time, check whether the first pipe and the second pipe are horizontally aligned.

[0026] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "lateral", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. in the present invention is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0028] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] As Figures 1-2 shown, a pipe centering deviation adjustment device of a preferred embodiment of the present invention includes an adjusting assembly 1, a support seat 2, and a fixing device 3;

[0030] The adjusting assembly 1 is connected to the support seat 2, the support seat 2 is fixedly connected to the fixing device 3, both the support seat 2 and the fixing device 3 are hollow and coaxially arranged, the support seat 2 and the fixing device 3 are used to pass through the first pipe 100, and the adjusting assembly 1 can adjust the first pipe 100 along the radial direction of the support seat 2.

[0031] Based on the above solution, first fix the second pipe, and then sleevethe support base 2 and the fixing device 3 on the first pipe 100 to be adjustedthrough a hollow coaxial structure. Use the adjusting component 1 on the supportbase 2 to adjust the position of the first pipe 100. At this time, check whetherthe first pipe 100 and the second pipe are horizontally aligned. The deviceadopts a hollow coaxial design of the support base 2 and the fixing device 3,which can be directly sleeved on the first pipe 100 to be adjusted withoutadditional disassembly or complex positioning steps. The adjusting component 1is integrated into the support base 2 and can achieve quick alignment throughradial fine adjustment. Using pure mechanical adjustment to replace weldingoperations completely eliminates the risk of eye injury to the operator causedby sparks. At the same time, it does not rely on angle iron codes for temporaryfixing, reducing the risk of high-temperature burns and mechanical damage atthe source. Traditional spot welding or fixing with angle iron codes will forma heat-affected zone at the pipe orifice. Especially for stainless steel pipes,the anti-corrosion performance is likely to decrease due to local high-temperature oxidation. The improved solution realizes fixation through non-weldingclamping, avoiding melting damage to the base material surface and reducingthe subsequent grinding process. Traditional spot welding requires multiple trial-and-error adjustments. The improved device shortens the centering time of thefirst pipe 100 and the second pipe through pre-positioning and quick clampingfunctions.

[0032] Furthermore, the adjusting component 1 includes at least two adjustingelements 11, and the at least two adjusting elements 11 are arranged atintervals along the circumferential direction of the support base. Thecircumferentially distributed adjusting elements 11 can achieve radial multi-angle fine adjustment of pipelines or shaft systems, effectively coping withcomplex misalignment deviations.

[0033] Furthermore, the adjusting element 11 includes a plurality of bolts 111.The bolts 111 are threadedly connected to the support base 2, and the pluralityof bolts 111 are arranged at intervals along the extending direction of thesupport base 2. The bolts 111 arranged at intervals along the extendingdirection of the support base 2 can independently or jointly adjust thevertical and horizontal displacements of the first pipe 100. The threadtransmission characteristics of the bolts 111 allow precise adjustment at themillimeter level, significantly improving the adjustment efficiency. Themultiple bolts 111 arranged at intervals can be operated in parallel, reducingthe repeated trial-and-error steps.

[0034] Furthermore, the adjusting element 11 includes a plurality of spacers112. The number of bolts 111 corresponds to the number of spacers 112 one byone. The spacers 112 are fixedly connected to the bolts 111 and are locatedinside the support base 2. Each spacer 112 independently corresponds to abolt 111, and can apply local adjustment forces to different contact points,avoiding excessive single-point pressure causing deformation of the pipe wall.The fixed connection between the spacers 112 and the bolts 111 forms a multi-point support structure. The design of the spacers 112 to disperse the load byincreasing the contact area can reduce the local stress concentration betweenthe support base 2 and the pipeline, especially suitable for the centeringrequirements of large-diameter pipelines.

[0035] Furthermore, the pipe centering deviation adjustment device further includes anti-slip teeth 4, which are fixedly connected to the inner side of the fixing device 3. The anti-slip teeth 4 engage with the pipe wall through a toothed structure, effectively preventing the pipe from axially sliding due to external force or vibration during the adjustment process. The toothed distribution of the anti-slip teeth 4 can disperse the clamping force to multiple contact points, thereby reducing the pressure per unit area of ​​the pipe wall.

[0036] Furthermore, the support seat 2 includes a support body 21 and a support outer ring 22 that are fixedly connected to each other, the support body 21 and the fixture 3 are coaxially arranged, and the fixture 3 is fixedly connected to the support outer ring 22. The coaxial design of the support body 21 and the fixture 3 forms a continuous force transmission path, which can reduce the bending stress caused by the eccentric load. The rigid connection between the support outer ring 22 and the fixture 3 forms an annular constraint, which can diffuse the local load to a larger contact surface, reduce the circumferential stress of the pipe wall, and optimize the mechanical properties.

[0037] Furthermore, there are two supporting outer rings 22, which are fixedly connected to both sides of the supporting body 21. The double supporting outer rings 22 form a symmetrical force transmission system, which can evenly transmit the load to both sides of the supporting body 21, effectively reducing unilateral stress concentration.

[0038] Furthermore, the number of the fixing devices 3 corresponds to the number of the supporting outer rings 22, and each fixing device 3 is fixedly connected to each supporting outer ring 22. The number of the fixing devices 3 matches the number of the supporting outer rings 22 to form a symmetrical force transmission path, and each fixing device 3 independently bears the local load of the corresponding outer ring. This design can avoid single-point overload and disperse the contact pressure of the pipe wall of the first pipe 100, which is particularly suitable for scenes with alternating loads or impact vibrations. The double supporting outer rings 22 cooperate with the double fixing devices 3 to form a closed force transmission frame, which can improve the overall torsional rigidity.

[0039] The working process of the present invention is as follows: fix the second tube to the target position using a fixture or a flange fixture, insert the hollow coaxial structure of the support seat 2 and the fixing device 3 into the outer wall of the first tube 100, and the anti-slip teeth 4 are engaged with the surface of the first tube 100, and the initial friction positioning is generated through the rubber tooth structure to prevent the first tube 100 from slipping, and the adjustment bolts 111 arranged at intervals in the circumference are operated to push the inner pad 112 to contact the first tube wall through threaded transmission. Since the bolts 111 are arranged in layers along the axial direction of the support seat 2, pressure can be applied in sections to form a multi-point support system. Start the laser alignment instrument or other instruments, install the transmitter and the receiver on the two ends of the first tube 100 and the second tube respectively, and monitor the axis deviation data in real time. According to the radial / axial deviation value fed back by the display, fine-tune the feed amount of the bolt 111 at a specific angle position.

[0040] In summary, the embodiment of the present invention provides a device for adjusting the alignment deviation of pipes. First, the second pipe is fixed, and then the support base 2 and the fixing device 3 are sleeved on the first pipe 100 to be adjusted through a hollow coaxial structure. The position of the first pipe 100 is adjusted by the adjusting component 1 on the support base 2. At this time, check whether the first pipe 100 and the second pipe are horizontally aligned. The device adopts the design of a hollow coaxial support base 2 and a fixing device 3, which can be directly sleeved on the first pipe 100 to be adjusted without additional disassembly or complex positioning steps. The adjusting component 1 is integrated into the support base 2 and achieves rapid alignment through radial fine adjustment. Using pure mechanical adjustment to replace welding operations completely eliminates the risk of eye injury to the operator caused by sparks. At the same time, there is no need to rely on angle iron codes for temporary fixation, reducing the risk of high-temperature burns and mechanical damage from the source. Traditional spot welding or fixing with angle iron codes will form a heat-affected zone at the pipe orifice. Especially for stainless steel pipes, the anti-corrosion performance is likely to decrease due to local high-temperature oxidation. The improved solution realizes fixation through non-welding clamping, avoiding melting damage to the surface of the base material and reducing subsequent grinding processes. Traditional spot welding requires multiple trial-and-error adjustments. The improved device shortens the centering time of the first pipe 100 and the second pipe through pre-positioning and rapid clamping functions.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
