Description

Technical Field

[0001] This application belongs to the field of welding technology, specifically relating to a tank weld assembly device. Background Technology

[0002] In the manufacturing process of stainless steel storage tanks, the assembly of the circumferential weld is a critical step, as its quality directly affects the tank's sealing performance, strength, and service life. Traditional assembly methods primarily rely on tools such as pry bars and locating pins to temporarily secure the tank, and initial positioning is achieved through spot welding. However, this method has the following significant problems: Weld point damage: Positioning spot welding leaves a large number of weld points on the surface of the tank wall, causing damage to the base material and increasing the workload of subsequent grinding and repair.

[0003] Deformation and misalignment: The thermal stress generated during welding can easily cause deformation of the wall panel, and it is difficult to accurately control the misalignment (usually required to be ≤1mm), which affects the assembly accuracy.

[0004] Inefficient: Traditional methods require multiple adjustments and repairs, have long construction cycles, and high labor costs, especially in large storage tank projects. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a tank weld assembly tool, which aims to at least partially solve the technical problem of low welding efficiency in storage tanks.

[0006] The technical solution of this utility model is as follows: A tank weld assembly tool includes: a support base; a connecting assembly, which is liftably mounted on the support base; a driving member, which is mounted on the support base and connected to the connecting assembly, for driving the connecting assembly to move up and down on the support base; a pull tab, which is detachably connected to the connecting assembly and passes through the weld between the tank wall plates of two tanks; and a stop block, which is detachably connected to the pull tab and abuts against the tank wall plates of the two tanks, wherein the stop block and the support base are respectively located on opposite sides of the tank wall plates.

[0007] In some embodiments, the support base includes: a first connecting portion connected to the drive member; a first support portion connected to the first connecting portion; and a second support portion connected to the end of the first connecting portion away from the first support portion.

[0008] In some embodiments, the second support portion is spaced apart from the first support portion to form a receiving groove; wherein the connecting component is elliptical and movable within the receiving groove.

[0009] In some embodiments, the connecting assembly includes: a first connector, which passes through the first connecting portion and connects to the driving member; a second connector, which is threaded to the first connector and detachably connected to the pull tab, the second connector being located between the first support portion and the second support portion; a first limiting member, which is disposed on the second connector and is slidably disposed on the first support portion; and a second limiting member, which is disposed on the second connector, the second limiting member and the first limiting member being respectively disposed on opposite sides of the second connector, the second limiting member being slidably disposed on the second support portion.

[0010] In some implementations, the first limiting member has a first groove, the first support portion is embedded in the first groove, the second limiting member has a second groove, and the second support portion is embedded in the second groove.

[0011] In some embodiments, the second connector includes: a second connecting portion threadedly connected to the first connector; and a third connecting portion angledly connected to the second connecting portion; wherein the pull tab is attached to the third connecting portion.

[0012] In some embodiments, the second connector further includes a limiting portion connected to the end of the third connector away from the second connector; wherein the pull tab is located between the limiting portion and the second connector.

[0013] In some embodiments, the pull tab includes: a first pull portion detachably connected to the connecting assembly; a second pull portion, one end of which is detachably connected to the first pull portion, and the other end passing through the weld between the tank wall plates of the storage tank, the second pull portion being detachably connected to the stop block.

[0014] In some embodiments, the first pulling part has a first through groove, the connecting component passes through the first through groove, the second pulling part has a second through groove, and the stop includes: a first stop that abuts against one of the tank wall plates of the two storage tanks; and a second stop that is connected to the first stop, the second stop passing through the second through groove and abutting against the other of the tank wall plates of the two storage tanks; wherein the width of the first stop is greater than the width of the second through groove, and the width of the second stop is less than or equal to the width of the second through groove.

[0015] In some implementations, a notch is provided at the connection between the first pulling part and the second pulling part.

[0016] The beneficial effects of this utility model include at least the following: Because the connecting assembly is liftably mounted on the support base, and the driving component is mounted on the support base and connected to the connecting assembly, it drives the connecting assembly to move up and down on the support base. The pull tab is detachably mounted on the connecting assembly and passes through the weld between the tank wall plates of the two tanks. The stop block is detachably connected to the pull tab and abuts against the tank wall plates of the two tanks. The stop block and the support base are located on opposite sides of the tank wall plates. Therefore, when assembling the circumferential welds of the two tanks, the pull tab is installed on the connecting assembly, and the support base is placed on the tank wall plates of the two tanks. The driving component lowers the connecting assembly on the support base so that the pull tab passes through the weld between the tank wall plates of the two tanks. Then, the stop block is installed... Mounted on the pull tab, the stop block and support base are located on opposite sides of the tank wall plates. The driving mechanism is activated, causing the connecting assembly to rise on the support base. The connecting assembly, through the pull tab, moves the stop block towards the tank wall plates, causing it to abut against the tank wall plates of the two tanks. The stop block applies force to the tank wall plates of the two tanks, aligning them. Then, spot welding is performed within the weld seam of the two tank wall plates, connecting them. The stop block is then removed from the pull tab, and the driving mechanism raises the connecting assembly on the support base. The connecting assembly pulls the pull tab out from the weld seam between the two tank wall plates, allowing for welding of the tank wall plates of the two tanks.

[0017] By using a pull tab to actuate the stop block, the stop block applies force to the tank wall plates of the two tanks, allowing for rapid alignment and fixation of the tank wall plates. This eliminates the need for tools such as pry bars or iron pins, preventing deformation and misalignment of the tank wall plates. It allows for precise adjustment of misalignment and gaps, ensuring that the misalignment of the circumferential seam between the two tank wall plates is ≤1mm and the gap is uniform (2-4mm). This significantly improves the accuracy of assembly and welding quality. Furthermore, it eliminates the need for multiple adjustments and repairs, resulting in a shorter construction period, lower labor costs, and increased welding efficiency. Simultaneously, it eliminates the need to weld numerous positioning blocks or pins onto the base material on both sides of the weld joint of the two tank wall plates, completely eliminating weld points and craters on the base material. This reduces subsequent grinding, repair welding, and maintenance work, significantly reducing the number of welding points and grinding workload, lowering labor costs and intensity, and protecting the tank wall plates from damage and deformation, thus ensuring the safety of the two tank wall plates.

[0018] The tank weld assembly device of this application only requires the drive component to drive the stop block through the connecting component and the pull plate, which can realize the quick alignment and fixation of the tank wall plates of two tanks. It has a simple structure, is easy to operate, and significantly reduces the complexity of construction.

[0019] This application allows for the selection of the number of tank weld assembly devices based on the diameter of the tank, enabling the tank weld assembly devices to be adapted to tanks of different diameters, thus improving versatility. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly.

If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0027] In the manufacturing process of stainless steel storage tanks, if tools such as pry bars and locating pins are not used to temporarily fix the tank to achieve the assembly of the circumferential weld, assembly fixtures (such as screw clamps, wedge clamps, magnetic clamps, etc.) are used to assemble the circumferential weld. However, in related technologies, the use of assembly fixtures still has the following limitations: Limited applicability: Some clamps are only applicable to storage tanks of specific diameters or materials, and have poor versatility.

[0028] The operation is complex: it requires the use of various tools such as temporary supports and jacks, the steps are complicated, and it requires high technical skills from workers.

[0029] Unavoidable solder joints: Temporary spot welding is required for fixation, which cannot fundamentally eliminate the negative impact of solder joints.

[0030] Based on these technical problems, this application provides a tank weld assembly tool, which aims to solve the technical problems of low welding efficiency and low versatility of assembly tooling for tanks.

[0031] The design concept of this application is as follows: by using a pull tab to drive the stop block, the stop block applies force to the tank wall plates of the two storage tanks, enabling the tank wall plates of the two storage tanks to be quickly aligned and fixed, thereby improving welding efficiency and reducing the labor intensity of installation personnel. The number of tank weld assembly devices can be selected according to the diameter of the storage tank, so that the tank weld assembly devices can be adapted to storage tanks of different diameters, improving versatility.

[0032] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized, illustrative, and not restrictive manner.

[0033] Combination Figure 1 The tank weld assembly device according to this application includes: a support base 10, a connecting assembly 20, a driving component 30, a pull tab 40, and a stop block 50. The connecting assembly 20 is movably mounted on the support base 10. The driving component 30 is mounted on the support base 10 and connected to the connecting assembly 20, used to drive the connecting assembly 20 to move up and down on the support base 10. The pull tab 40 is detachably connected to the connecting assembly 20 and passes through the weld between the tank wall plates 60 of the two tanks. The stop block 50 is detachably connected to the pull tab 40 and abuts against the tank wall plates 60 of the two tanks. The stop block 50 and the support base 10 are located on opposite sides of the tank wall plates 60.

[0034] Since the connecting assembly 20 is liftably mounted on the support base 10, and the driving component 30 is mounted on the support base 10 and connected to the connecting assembly 20, driving the connecting assembly 20 to move up and down on the support base 10, the pull tab 40 is detachably mounted on the connecting assembly 20 and passes through the weld between the tank wall plates 60 of the two tanks, and the stop block 50 is detachably connected to the pull tab 40 and abuts against the tank wall plates 60 of the two tanks, with the stop block 50 and the support base 10 located on opposite sides of the tank wall plates 60, when assembling the circumferential welds of the two tanks, the pull tab 40 is installed on the connecting assembly 20, and the support base 10 is placed on the tank wall plates 60 of the two tanks. The driving component 30 drives the connecting assembly 20 to descend on the support base 10 so that the pull tab 40 passes through the weld between the tank wall plates 60 of the two tanks. Then, the stop block 50 is installed... At this time, the stop block 50 and the support base 10 are located on opposite sides of the tank wall plate 60. The drive component 30 is operated, which drives the connecting component 20 to rise on the support base 10. The connecting component 20 drives the stop block 50 to move towards the tank wall plate 60 through the pull tab 40, so that the stop block 50 abuts against the tank wall plates 60 of the two tanks. The stop block 50 applies force to the tank wall plates 60 of the two tanks to align them. Then, spot welding is performed in the weld seam of the tank wall plates 60 of the two tanks to connect them. Then, the stop block 50 is removed from the pull tab 40, and the drive component 30 drives the connecting component 20 to rise on the support base 10. The connecting component 20 pulls the pull tab 40 out from the weld seam between the tank wall plates 60 of the two tanks, so that the tank wall plates 60 of the two tanks can be welded.

[0035] By using the pull plate 40 to drive the stop block 50, the stop block 50 applies force to the tank wall plates 60 of the two tanks, enabling the tank wall plates 60 of the two tanks to be quickly aligned and fixed. This eliminates the need for tools such as pry bars and iron bars, preventing deformation and misalignment of the tank wall plates 60. It allows for precise adjustment of the misalignment and gap, ensuring that the misalignment of the circumferential seam of the two tank wall plates 60 is ≤1mm and the gap is uniform (2-4mm). This significantly improves the accuracy of the assembly and the welding quality. Moreover, it eliminates the need for multiple adjustments and repairs, resulting in a shorter construction cycle, lower labor costs, and improved welding efficiency. At the same time, it is not necessary to weld a large number of positioning blocks or positioning pins on the base material on both sides of the weld joint of the tank wall plates 60 of the two storage tanks, completely eliminating the weld points and weld pits on the base material on both sides of the weld joint of the tank wall plates 60 of the two storage tanks, reducing subsequent grinding, welding and repair work, significantly reducing the amount of welding points and grinding work, reducing labor costs and labor intensity, and also protecting the tank wall plates 60 of the two storage tanks from damage and deformation, thus ensuring the safety of the tank wall plates 60 of the two storage tanks.

[0036] The tank weld assembly device of this application only requires the drive component 30 to drive the stop block 50 through the connecting component 20 and the pull plate 40, so that the tank wall plates 60 of two tanks can be quickly aligned and fixed. It has a simple structure, is easy to operate, and significantly reduces the complexity of construction.

[0037] This application allows for the selection of the number of tank weld assembly devices based on the diameter of the tank, enabling the tank weld assembly devices to be adapted to tanks of different diameters, thus improving versatility.

[0038] In related technologies, the storage tank is made of stainless steel. Stainless steel is extremely sensitive to carburization and contamination. Using carbon steel tools or improper operation may cause surface rust, further increasing the difficulty of quality control. In some embodiments, the support base 10, pull tab 40, and stop block 50 are all made of stainless steel to prevent carbon steel tools from contacting the tank wall plate 60 of the stainless steel storage tank, prevent carburization and rust, and meet the construction requirements of stainless steel storage tanks.

[0039] Combination Figure 1 In some embodiments, to support the connecting assembly 20, the support base 10 includes: a first connecting portion 11, a first supporting portion 12, and a second supporting portion 13. The first connecting portion 11 is connected to the driving member 30 and supports the driving member 30 through the first connecting portion 11. The first supporting portion 12 is connected to the first connecting portion 11. The second supporting portion 13 is connected to the end of the first connecting portion 11 away from the first supporting portion 13, and supports the first connecting portion 11 through the first supporting portion 12 and the second supporting portion 13.

[0040] In some embodiments, to facilitate the lifting and lowering of the connecting component 20, the second support portion 13 is spaced apart from the first support portion 12 to form a receiving groove 14. The connecting component 20 is vertically detachable in the receiving groove 14, which accommodates the connecting component 20 and provides space for its movement.

[0041] Combination Figure 1 In some embodiments, to achieve the lifting and lowering of the connecting assembly 20, the connecting assembly 20 includes: a first connecting member 21, a second connecting member 22, a first limiting member 23, and a second limiting member 24. The first connecting member 21 passes through the first connecting portion 11 and is connected to the driving member 30. The second connecting member 22 is threadedly connected to the first connecting member 21 and detachably connected to the pull tab 40. The second connecting member 22 is located between the first support portion 12 and the second support portion 13. The first limiting member 23 is disposed on the second connecting member 22 and is slidably disposed on the first support portion 12. The second limiting member 24 is disposed on the second connecting member 22, and is disposed on opposite sides of the first limiting member 23. The second limiting member 24 is slidably disposed on the second support portion 13. For example, the driving member 30 is a nut, and the first connecting member 21 is a screw.

[0042] The driving component 30 is operated, which drives the first connecting component 21 to rotate. The first connecting component 21 rotates within the second connecting component 22, thereby driving the second connecting component 22 to move. At this time, the first limiting component 23 slides on the first support part 12, and the second limiting component 24 slides on the second support part 13. The first limiting component 23 and the second limiting component 24 limit the second connecting component 22 so that the second connecting component 22 can only perform lifting and lowering movements, but cannot perform rotating movements. The second connecting component 22 can drive the pull tab 40 to lift and lower.

[0043] Of course, in some other embodiments, the drive component 30 can be a motor or a handle, and the connecting component 20 can be a ball screw. By starting the motor or operating the handle, the pull plate 40 can be raised or lowered by the ball screw.

[0044] Of course, in some other embodiments, the driving member 30 can be a telescopic member. For example, the first telescopic member can be an electric push rod, a cylinder, or a hydraulic cylinder. The connecting assembly 20 can be a connecting rod. The fixed end of the telescopic member is located on the first connecting portion 11, which supports the fixed end of the telescopic member. The moving end of the telescopic member passes through the first connecting portion 11 and connects to the connecting rod, so that the connecting rod can drive the pull plate 40 to rise and fall. In some embodiments, in order to enable the first limiting member 23 to slide on the first support portion 12, the first limiting member 23 is provided with a first groove, and the first support portion 12 is embedded in the first groove.

[0045] In some embodiments, in order to enable the second limiting member 24 to slide on the second support portion 13, the second limiting member 24 is provided with a second groove, and the second support portion 13 is embedded in the second groove.

[0046] Combination Figure 1 In some embodiments, to enable the pull tab 40 to be detachably connected to the connecting assembly 20, the second connecting member 22 includes a second connecting portion 221 and a third connecting portion 222. The second connecting portion 221 is threadedly connected to the first connecting member 21. The third connecting portion 222 is connected to the second connecting portion 221 at an angle. For example, the included angle between the second connecting portion 222 and the second connecting portion 221 can be a right angle. The pull tab 40 is attached to the third connecting portion 222.

[0047] When installing the pull tab 40, simply hang the pull tab 40 on the third connecting part 222. When removing the pull tab 40, simply remove the pull tab 40 from the third connecting part 222.

[0048] Combination Figure 1 In some embodiments, when the pull tab 40 is attached to the third connecting portion 222, to prevent the pull tab 40 from falling off the third connecting portion 222, the second connecting member 22 further includes a limiting portion 223. The limiting portion 223 is connected to the end of the third connecting portion 22 away from the second connecting portion 221. The pull tab 40 is located between the limiting portion 223 and the second connecting portion 221, and the limiting portion 223 blocks the pull tab 40, preventing it from falling off.

[0049] Combination Figure 1 and Figure 2 In some embodiments, in order for the connecting assembly 20 to drive the pull tab 40 to move up and down, the pull tab 40 includes a first pulling part 41 and a second pulling part 42. The first pulling part 41 is detachably connected to the connecting assembly 20. One end of the second pulling part 42 is detachably connected to the first pulling part 41, and the other end passes through the weld between the tank wall plates 60 of the storage tank. The second pulling part 42 is detachably connected to the stop block 50.

[0050] When the pull tab 40 is to be raised or lowered, the connecting assembly 20 drives the second pull part 42 to be raised or lowered through the first pull part 41.

[0051] Combination Figure 1 and Figure 2 In some embodiments, the first pull part 41 has a first through groove 411, and the connecting component 20 passes through the first through groove 411. For example, the area of ​​the first through groove 411 is larger than the area of ​​the limiting part 223 of the connecting component 20, so that the first pull part 41 can be hung on the third connecting part 222 of the connecting component 20.

[0052] When the first pull part 41 is to be connected to the connecting component 20, the third connecting part 222 of the connecting component 20 is passed through the first through slot 411.

[0053] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, to allow the stop block 50 to abut against the tank wall plates 60 of the two storage tanks, the second pulling part 42 is provided with a second through groove 421. The stop block 50 includes a first stop portion 51 and a second stop portion 52. The first stop portion 51 abuts against one of the tank wall plates 60 of the two storage tanks. The second stop portion 52 is connected to the first stop portion 51, passes through the second through groove 421, and abuts against the other tank wall plate 60 of the two storage tanks. The width of the first stop portion 51 is greater than the width of the second through groove 421, and the width of the second stop portion 52 is less than or equal to the width of the second through groove 421.

[0054] When the second pulling part 42 passes through the weld between the tank wall plates 60 of the two storage tanks, the second stop part 52 passes through the second through groove 421. The connecting assembly 20 drives the second pulling part 42 to move upward through the first pulling part 41. The second pulling part 42 drives the first stop part 51 and the second stop part 52 to move upward, so that the first stop part 51 and the second stop part 52 respectively abut against the tank wall plates 60 of the two storage tanks. The first stop part 51 and the second stop part 52 can respectively apply force to the tank wall plates 60 of the two storage tanks.

[0055] Since the width of the first stop 51 is greater than the width of the second through groove 421, and the width of the second stop 52 is less than or equal to the width of the second through groove 421, the stability of the stop 50 installed on the second pull part 42 can be guaranteed, and the possibility of the stop 50 falling off can be reduced.

[0056] After the stop block 50 is removed from the pull tab 40, the drive member 30 causes the connecting assembly 20 to rise on the support base 10. The pull tab 40 may get caught in the weld between the tank wall plates 60 of the two storage tanks, making it impossible to remove the pull tab 40. In some embodiments, a notch 43 is provided at the connection between the first pull part 41 and the second pull part 42 in order to allow the pull tab 40 to be removed.

[0057] After the stop block 50 is removed from the pull tab 40, the drive component 30 drives the connecting assembly 20 to rise on the support base 10. The pull tab 40 will be clamped between the tank wall plates 60 of the two storage tanks. At this time, the drive component 30 continues to drive the first pulling part 41 to move upward through the connecting assembly 20. Since there is a notch 43 at the connection between the first pulling part 41 and the second pulling part 42, the second pulling part 42 and the first pulling part 41 can break at the notch 43, so that the second pulling part 42 and the first pulling part 41 can be separated, and the pull tab 40 can be removed to avoid interfering with the subsequent welding work.
