Description

Technical Field

[0001] This technical solution relates to the field of assembly technology, specifically a quick leveling triangular tool. Background Technology

[0002] The plate assembly method is a ship section assembly process, commonly used in steel structure assembly. It uses plate as a temporary connecting component, and through precise positioning and welding to fix adjacent sections, it achieves rapid docking of the hull structure while controlling accuracy and deformation. It is widely used in the shipbuilding industry.

[0003] In existing shipbuilding, the traditional leveling and positioning process generally adopts the plate welding assembly method. The plate alignment and weld flatness control are achieved by welding temporary fixing components. The disassembly operation requires the use of cutting tools to remove the main structure of the plate, and then mechanical grinding to remove residual weld points. However, thermal cutting and mechanical grinding operations can easily cause irreversible damage to the surface integrity of the base material. In addition, this construction mode requires multiple processes such as cutting and grinding, resulting in low construction efficiency and complicated operation. Summary of the Invention

[0004] This technical solution provides a quick leveling triangle tool to improve the problem of low efficiency caused by the complicated process of welding and leveling of the welding plate.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A quick-leveling triangular tool for leveling and aligning two adjacent bulb flats or two T-profiles, comprising:

[0007] The tripod plate has a pressing section extending from its front side;

[0008] A fixing device is provided on the tripod plate, and the lower part of the fixing device has a clamping cavity for clamping steel, which is used to fix the tripod plate on the steel.

[0009] The top pressing device has its output end abutting below the top pressing part. The top pressing device pushes out through its output end to push the top pressing part, thereby pushing the two steel pieces to move relative to each other and level them.

[0010] Through the above technical solution, when a quick leveling triangular tool is in normal use, the fixing device mounted on the triangular frame plate forms an interlocking positioning through the clamping cavity at its lower part via the web of the bulb flat steel / T-section, so that the triangular frame plate is stably erected above the steel. At the same time, the top pressing device is fixed to the adjacent steel. When its drive output end extends, it pushes the top pressing part at the front end of the triangular frame plate, forming a lever effect with the fixing device as the fulcrum, pushing the two steels to move relative to each other until they are close to each other and aligned at the same level. The entire process of steel alignment and force application leveling can be completed in a single clamping, reducing the steps of repeatedly adjusting the tooling fixtures and improving the efficiency of the closing operation.

[0011] Preferably, the fixing device includes:

[0012] Left fixed ornament;

[0013] The right fixed ornament is hinged to the left fixed ornament on opposite sides of the tripod plate. The opposite sides of the tripod plate are provided with hinge shafts. Both the left and right fixed ornaments are provided with hinge holes for the hinge shafts to pass through.

[0014] Both the left and right fixed ornaments are provided with downwardly extending clamping portions, and the clamping cavities are formed between the clamping portions on both sides.

[0015] With the above technical solution, when the tripod plate is placed on the steel, the hinge holes of the left and right fixed ornaments are aligned with the hinge shaft for fitting, thereby completing the installation. Similarly, left and right fixed ornaments of different sizes and specifications can be selected to suit different profiles. At this time, the steel is just within the limiting channel between the left and right fixed ornaments for constraint, realizing the stable installation of the tripod plate and improving assembly efficiency.

[0016] Preferably, a clearance channel is provided between the clamping portions on both sides, and the clearance channel is connected to the clamping cavity.

[0017] Through the above technical solution, the clearance channel reserved between the lower leveling parts of the left and right fixed swing parts is connected with the upper limiting channel to form a continuous guiding space, so that the channel is suitable for T-shaped steel, making the tooling compatible with the universal leveling of angle steel and T-shaped steel, thus improving practicality.

[0018] Preferably, both the left and right fixed pendant are provided with an adjustment mechanism between themselves and their corresponding hinge shafts, and the adjustment mechanism is used to adjust the rotation angle of the left and right fixed pendant.

[0019] Through the above technical solution, the operator can change the initial angle of the left and right fixed swing parts around the hinge axis by rotating the adjustment mechanism, and control the contact angle between the leveling part and the steel surface. When the tooling is adapted to different profiles such as T-shaped steel and angle steel, the opening and closing angle of the left and right swing parts can be adjusted according to the thickness of the profile. The leveling part is close to the steel for clamping, which increases the constraint force on the steel and reduces the swing caused by the gap between the inner wall of the limiting channel and the steel, thereby further improving stability.

[0020] Preferably, the fixing device includes

[0021] The first snap-fit ​​part has an anti-detachment protrusion at its lower part, and the first snap-fit ​​part is snapped onto one side of the steel material through the anti-detachment protrusion.

[0022] The second snap-fit ​​part is located on opposite sides of the tripod plate, and the clamping cavity is formed between the second snap-fit ​​part and the first snap-fit ​​part.

[0023] The second snap-fit ​​part is provided with a leveling pin and a connecting hole. The leveling pin is threaded to the connecting hole and is adjusted along the axial direction of the connecting hole. The leveling pin and the anti-loosening protrusion abut against the opposite sides of the steel.

[0024] Through the above technical solution, the anti-detachment protrusion is pre-fixed by inserting into one side of the steel. Then, the leveling pin is screwed on so that its end is pressed against the other side of the steel, forming a two-way mechanical locking structure. This securely clamps the tripod plate onto the steel. When the top pressing device pushes the top pressing part, the leveling pin cooperates with the anti-detachment protrusion to limit the displacement direction of the tripod plate. The threaded connection structure allows the leveling pin to adjust its length along the axial direction, adapting to the quick clamping of steel of different sizes, while ensuring clamping rigidity and improving the versatility and ease of operation of the leveling process.

[0025] Preferably, the tripod plate is further provided with a mounting assembly, the mounting assembly comprising:

[0026] The mounting part 1 has an extension part 1 extending towards the top pressing device. The end of the extension part 1 is provided with a connecting hole 2, and the connecting hole 2 is threadedly connected to a leveling pin 2.

[0027] Mounting part two, which is respectively set on the opposite sides of the tripod plate with mounting part one. Mounting part two extends into extension part two in the direction close to the top pressing device. The end of extension part two is provided with connecting hole three. Leveling pin three is threadedly connected to connecting hole three. Leveling pin two and leveling pin three are respectively adjusted along the axial direction of connecting hole two and connecting hole three, so as to abut against the two sides of the steel.

[0028] With the above technical solution, the tripod plate is clamped on one side of the steel. When horizontally aligned, the leveling pins two and three are screwed on to move axially along the corresponding connecting holes. The leveling pins two and three approach each other and their ends abut against the two side walls of the other side of the steel to form a horizontal clamp, so that the steel is laterally aligned with the steel below the tripod plate, ensuring the horizontal alignment between the two steels. This is suitable for irregularly shaped steels such as bulb flat steel that need to be laterally aligned. Through the composite leveling mechanism of double pin symmetrical clamping and top pressure linkage, the lateral positioning and longitudinal leveling are completed simultaneously, further improving the alignment efficiency and accuracy.

[0029] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0030] 1. This technical solution uses a tripod plate fixed by a fixed device to position the steel material one. The top pressing device drives the output end to extend out to press the top pressing part of the tripod plate. With the fixed device as the fulcrum, a lever effect is formed, which accurately drives the steel materials one and two to move relative to each other until they are aligned, thus improving the efficiency of the closing operation.

[0031] 2. This technical solution uses a fixing device including a left fixed swing member and a right fixed swing member. The left and right fixed swing members are hinged to both sides of the tripod plate to form a symmetrical clamping structure. The hinge holes and hinge shafts can be quickly engaged to achieve modular installation. The limiting channel constrains the movement trajectory of the steel, so that the tripod plate is fixed to the steel. It is suitable for T-shaped steel and improves the efficiency of use.

[0032] 2. This technical solution uses a fixing device including a first clamping part and a second clamping part. The first clamping part is clamped to one side of the steel by an anti-loosening protrusion. The second clamping part is threaded to an axially movable adjusting pin by a connecting hole. By moving the adjusting pin, it engages with the anti-loosening protrusion to clamp the steel on both sides, thus fixing the triangular plate to the steel. This solution is suitable for bulb flat steel. Attached Figure Description

[0040] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0041] Example 1:

[0042] See Figure 1 A quick-leveling triangular tool is used to align adjacent steel pieces 100 and 200. It includes a triangular frame 1, a fixing device 3, and a pressing device 5. The lower part of the triangular frame 1 is a triangular frame. The lower end face of the triangular frame 1 is flat and can stably abut against the steel piece 100. The front side wall of the triangular frame 1 is flat and perpendicular to the lower end face. The top of the triangular frame 1 extends forward with a pressing part 2. The angle between the lower end face of the pressing part 2 and the front side wall of the triangular frame 1 is 90°, so that the lower end face of the pressing part 2 can be nearly parallel to the upper end face of the steel piece 200.

[0043] See Figure 1 and Figure 2 The fixing device 3 includes a left fixed swing member 31 and a right fixed swing member 32. The left fixed swing member 31 and the right fixed swing member 32 have similar structures. The left fixed swing member 31 and the right fixed swing member 32 are symmetrically arranged on opposite sides of the tripod plate 1 along the thickness direction. The left fixed swing member 31 and the right fixed swing member are both hinged to the tripod plate 1, and the hinge axis 8 is collinear. The specific hinge method is that the left fixed swing member 31 and the right fixed swing member 32 are provided with hinge holes 9. The tripod plate 1 has hinge axes 8 extending outward on opposite sides along the thickness direction. The left fixed swing member 31 and the right fixed swing member 32 are fitted with the corresponding hinge axis 8 by aligning the position of the hinge holes 9 on the left fixed swing member 31 and the right fixed swing member 32, so that the left fixed swing member 31 and the right fixed swing member 32 can rotate around the corresponding hinge axis 8 as the hinge axis 8 line.

[0044] The lower parts of the left fixed ornament 31 and the right fixed ornament 32 are hook-shaped, forming a clamping cavity 11 between the left fixed ornament 31 and the right fixed ornament 32 for the steel material to pass through. Both the left fixed ornament 31 and the right fixed ornament have a leveling part 4, which is located at the lower end of the corresponding fixed ornament. The leveling parts 4 on both sides face each other, and a clearance channel 12 is left between the leveling parts 4 on both sides. The upper side of the clearance channel 12 is connected to the clamping cavity 11, so that the size formed by the clearance channel 12 and the clamping cavity 11 is adapted to the T-shaped material.

[0045] See Figure 2 and Figure 3 See Figure 2 and Figure 3 The pressing device 5 is preferably a cylinder or a hydraulic cylinder, which is located on the front side of the tripod plate 1 and below the pressing part 2. When the pressing device 5 is placed on the steel part 200, its output end is located above the pressing part 2. Specifically, the output end can be a piston rod structure that can extend or retract on the pressing device 5. The output end of the pressing device 5 abuts against the lower end face of the pressing part 2. The pressing device 5 drives the output end to extend to apply a thrust to the pressing part 2. Based on the interaction of forces, the pressing device 5 and the tripod plate 1 have a tendency to move relative to each other. The pressing device 5 applies downward pressure to the steel part 200. The tripod plate 1 pulls the steel part 100 through the fixing device 3, causing the steel part 200 and the steel part 100 to approach each other and become flush, until the steel part 200 abuts against the fixing pin 16 and cannot move.

[0046] The left fixed ornament 31 and the right fixed ornament 32 are each provided with an adjustment mechanism between the corresponding hinge shaft 8. The left fixed ornament 31 and the right fixed ornament 32 adjust the rotation angle and lock through the adjustment mechanism. The adjustment mechanism can be a number of adjustment grooves arranged around the hinge column and a number of adjustment protrusions protruding around the inner wall of the hinge hole 9. The number of adjustment protrusions corresponds one-to-one with the number of adjustment grooves. The rotation angle is adjusted by the adjustment grooves corresponding to different adjustment protrusions. Alternatively, the hinge column can be provided with a number of adjustment protrusions protruding around the circumference and the inner wall of the hinge hole 9 can be provided with a number of adjustment grooves recessed around the circumference.

[0047] The specific work process of this plan is as follows:

[0048] This technical solution is used for the assembly and positioning of T-shaped steel. The tripod plate 11 is positioned on one side of the steel by the left fixed swing member 31 and the right fixed swing member 32. The steel is correspondingly fitted into the clamping cavity 11. The top pressing device 5 is fixed to the adjacent steel. When its drive output end extends, it pushes the top pressing part 2 at the front end of the tripod plate 1, forming a lever effect with the fixed device 3 as the fulcrum, pushing the two steels to move relative to each other until they are close to each other and aligned at the same level. The entire process of steel alignment and force leveling can be completed in a single clamping, reducing the steps of repeatedly adjusting the tooling fixtures and improving the efficiency of the closing operation.

[0049] Example 2:

[0050] See Figure 4 and Figure 5 A quick leveling triangular tool, differing from Embodiment 1 in that the steel is preferably a bulb flat steel, with two steel materials being steel material one 100 and steel material two 200. The fixing device 3 includes a first snap-fit ​​part 41 and a second snap-fit ​​part 42. The first snap-fit ​​part 41 and the second snap-fit ​​part 42 are integrally connected to opposite sides of the tripod plate 1 and are located at the rear bottom of the tripod plate 1 away from the top pressing part 2. The first snap-fit ​​part 41 has a protruding anti-detachment protrusion 17, which is located at the lower end of the first snap-fit ​​part 41 and protrudes in a hook shape towards the second snap-fit ​​part 42. A clamping cavity 11 adapted to the top end of the bulb flat steel is formed between the second snap-fit ​​part 42 and the first snap-fit ​​part 41, so that the anti-detachment protrusion 17 can be snapped into one side of the steel material one 100 to achieve pre-fixation.

[0051] The second snap-fit ​​part 42 has a connecting hole 81, which passes through the second snap-fit ​​part 42 in a horizontal direction and is arranged in a direction corresponding to the distribution direction of the first snap-fit ​​part 41 and the second snap-fit ​​part 42. The inner peripheral wall of the connecting hole 81 has an internal thread structure. The leveling pin 161 of the second snap-fit ​​part 42 has an external thread structure. The leveling pin 161 is threadedly connected in the connecting hole 81. By rotating the thread of the leveling pin 161, it moves axially along the connecting hole 81. The end of the leveling pin 161 approaches the steel. The leveling pin 161 and the anti-disengagement protrusion 17 on the other side form a double-sided clamping and positioning, thereby fixing the tripod plate 1 on the steel 100.

[0052] See Figure 5 and Figure 6The tripod plate 1 mounting assembly 16 includes a mounting part 1 61 and a mounting part 2 62. The mounting part 1 61 and the mounting part 2 62 are integrally connected to the bottom of opposite sides of the tripod plate 1, and are positioned in front of the first snap-fit ​​part. The mounting part 1 61 has an extension part 71 extending towards the pressing device 5. The end of the extension part 1 71 has a connecting hole 2 82. The inner peripheral wall of the connecting hole 2 82 has an internal thread structure. The connecting hole 2 82 is connected to the leveling pin 2 162. The leveling pin 2 162 has an external thread structure and is threadedly connected to the connecting hole 2 82. The mounting part 2 62 has an extension part extending towards the pressing device 5. The end of extension 272 has a through-hole 383. The inner circumferential wall of connection hole 383 has an internal thread structure. Connection hole 383 is threadedly connected to leveling pin 3163. By rotating leveling pin 2162 and leveling pin 16, they can move axially along the thread direction. The rotation axes of leveling pin 2162 and leveling pin 3163 are parallel to each other. When leveling pin 2162 and leveling pin 3163 approach each other, their ends abut against the opposite sides of steel 200 to form a horizontal clamp. Adjusting the position of steel 200 can keep it laterally aligned with steel 100 to ensure that when the vertical height is aligned laterally, the large ends of the two steel materials (such as bulb flat steel) can be aligned.

[0053] The specific work process of this plan is as follows:

[0054] This technical solution is applicable to the assembly and positioning of bulb flat steel. Using a tripod plate 1 as the main structure, a single-sided pre-fixation of steel 100 is achieved through an anti-detachment protrusion 17. A connecting hole on the snap-fit ​​part 42 houses a screw-in leveling pin 161, which, together with the anti-detachment protrusion 17, forms a double-sided clamping mechanism, ensuring a stable assembly between the tripod plate 1 and steel 100. The front-mounted assembly 16 includes symmetrically distributed mounting parts 61 and 62, each extending with a threaded hole. A horizontal clamping mechanism is formed by screwing in leveling pins 162 and 163. The axes of the two leveling pins are parallel, and when screwed in synchronously, they abut against both sides of steel 200 to achieve lateral fine-tuning, ensuring that steel 200 and steel 100 remain axially aligned. This design, through a multi-directional adjustable clamping mechanism, achieves lateral positioning of the two steels during the pre-fixation stage, laying a precise alignment foundation for subsequent vertical height leveling.
