Description

Technical Field

[0001] This invention relates to support and protection mechanisms, specifically to support and protection mechanisms and methods for building steel structures, belonging to the technical field of steel structure processing equipment. Background Technology

[0002] Steel structures are structures made of steel and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust-proofing processes. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion; generally, they require rust removal, galvanizing, or painting, and regular maintenance.

[0003] Because different steel materials are used in the welding of steel structures, such as square tubes, rectangular tubes and I-beams, special support structures are required during welding, and they need to have good clamping and protection functions to prevent deformation and positional deformation during welding. However, most common support and protection structures are applied to a single steel material. Each time a different steel material is changed, the support and clamping protection structure needs to be disassembled and replaced, which requires manual adjustment and operation. It is difficult to guarantee the positional accuracy. Moreover, the pre-positioning structure also needs to be improved due to the shape characteristics of different steel materials. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a support and protection mechanism and method for building steel structures to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0011] Preferably, the second side frame is fixed on the second movable frame, and the second side frame is provided with a through rotating slot, in which the limiting block rotates.

[0012] The rotating slot is provided with a rotating opening and an array of second positioning holes.

The sliding end of the first electric slide is provided with a fourth lifting plate that is fixedly connected. The sliding end of the second electric slide is provided with a fifth lifting plate that is fixedly connected. The sliding end of the third electric slide is provided with a sixth lifting plate that is fixedly connected. The third lifting plate is installed below the fourth, fifth, and sixth lifting plates.

[0013] Preferably, the second clamping assembly includes a rotatable third connecting frame, and a threaded second lead screw is provided inside the third connecting frame. One end of the second lead screw is provided with a first push plate and a second push plate that are rotatably connected, and the other end of the second lead screw is provided with a turntable that is fixedly connected. The first push plate is provided with two sets of magnets that are symmetrically distributed, and the second push plate is provided with four sets of iron plates arranged in a cross shape. The second push plate can be rotated to adjust its position relative to the first push plate, and can rotate 90° at a time. The magnets attract the iron plates for positioning.

[0014] Preferably, the support angle of the first lifting plate can be changed, and the connection between the first push plate, the second push plate and the second lead screw is changed to a universal joint structure.

[0015] Preferably, the limiting block is provided with rotating columns at both the upper and lower ends, and the rotating columns are rotatably connected to the rotating opening. The upper end of the limiting block is provided with an array of third positioning holes. When the limiting block is horizontal with the second side frame, the third positioning holes are concentric with the second positioning holes.

[0016] The limiting block is provided with symmetrically distributed first guide plates on one side, the front end of the first guide plate is an inclined edge, and the back of the first guide plate is provided with arrayed first dampers.

[0018] Springs are provided on the outside of the first damper, the second damper, and the third damper.

[0019] A support and protection method for a support and protection mechanism for a building steel structure includes the following steps:

[0020] Select the appropriate limiting block side according to the vertical welded parts to be clamped. When it is necessary to clamp square tubes or rectangular tubes, select the first guide plate. When it is necessary to clamp I-beams, select the second guide plate and the third guide plate. After selection, fix the limiting block in the rotating slot, and then install the vertical welded parts into the limiting block. The second lifting plate pushes the vertical welded parts to adjust the height.

[0021] When welding is required on the lowest side of the vertical weldment, the vertical weldment is supported and protected by the limit block. The second clamping cylinder drives the third connecting frame to rotate and become horizontal with the second side frame. The second screw rotates to push the second push plate to contact the vertical weldment and lock it. The horizontal weldment is placed on the third lifting plate and the first lifting plate for support. The third lifting plate and the first lifting plate adjust the height of the horizontal weldment relative to the vertical weldment. The third side frame rotates to close. The first screw rotates to drive the first push block forward to squeeze the horizontal weldment. The fifth electric cylinder pushes the vertical weldment forward to contact the horizontal weldment. Then the welding device performs welding. After welding is completed, the first clamping assembly and the second clamping assembly retract to unlock. The fifth electric cylinder drives the entire weldment to retract and remove the entire weldment.

[0022] When multiple sets of transverse weldments need to be welded on the side of a vertical weldment, the positioning welding should be carried out sequentially from the top of the vertical weldment downwards. When the transverse weldment is long, insert the insert plate into the slot and place the transverse weldment on the insert plate at the specified height. Since the steel part is long, the two ends may droop. The fourth lifting plate, the fifth lifting plate, or the fourth lifting plate and the sixth lifting plate make fine adjustments to the height of the welding end. The first clamping assembly and the second clamping assembly lock the weldment. The fifth electric cylinder pushes the vertical weldment forward to contact the transverse weldment, so that the contact surfaces of the two are perpendicular. Then the welding device performs welding. After the welding is completed, the first clamping assembly and the second clamping assembly move back to unlock. The fifth electric cylinder drives the entire weldment to move back and remove the entire weldment.

[0023] When the welded part is tilted, change the connection method of the first push plate, the second push plate and the second lead screw, unlock the rotating shaft, the first motor drives the rotating shaft and the first lifting plate to rotate the angle, and then the second electric cylinder pushes the first lifting plate to rise, so that the first lifting plate supports the tilted bottom of the transverse welded part. When the second push plate and the first push block contact the side of the transverse welded part, they rotate and fit together with their own tilted surfaces.

[0024] The beneficial effects of this invention are:

[0025] 1. The support and protection mechanism of this invention can effectively support and protect steel structures during welding, avoiding the limitations of existing simple clamps. It can be adjusted according to the required steel structure style, greatly improving welding accuracy, eliminating manual debugging time, and improving work efficiency.

[0026] 2. The limiting block in the support and protection mechanism of this invention can be rotated and adjusted according to the welded steel structure as needed. It can be used for clamping and limiting square tubes, rectangular tubes, and I-beams, and can be used for welded parts of different sizes, which improves applicability and eliminates the need for large-area clamp replacement and adjustment.

[0027] 3. The support and protection mechanism of the present invention can support and adjust steel structure welded parts of different lengths. It can adjust the height of the steel structure welded parts and the horizontality of the contact surface, so that the steel structure weld can make vertical contact. It has good support and adjustability, and avoids detachment and breakage caused by uneven contact position of steel structure weld.

[0028] 4. The support and protection mechanism of the present invention can also make corresponding adjustments for irregularly shaped and inclined steel structure welded parts. When the steel structure welded parts are inclined, the first push plate and the second push plate are replaced with universal joint structures, the first lifting plate can rotate to provide support, and the second push plate and the first push block rotate and fit with their own inclined surfaces when they contact the side of the transverse welded parts, which further improves the support and protection of the steel structure during welding and prevents the steel structure from falling off or shifting during the welding process.

When the welded part to be clamped is not... When the plane is horizontal, the connection between the first push plate 73, the second push plate 74 and the second lead screw 72 can be changed to a universal joint structure to meet the requirements of inclined support. The other end of the second lead screw 72 is provided with a turntable that is fixedly connected. The first push plate 73 is provided with two sets of magnets 731 symmetrically distributed, and the second push plate 74 is provided with four sets of iron plates 741 arranged in a cross shape.

The long side of the second push plate 74 is used to push and compress the square or rectangular tube. Figure 10 As shown, the second lifting plate 531 pushes the square tube and rectangular tube to adjust their height relative to the limiting block 8;

[0057] On the other side of the limiting block 8, there is a fixedly connected mounting bracket 84. Inside the mounting bracket 84 is a movable second guide plate 85. Between the second guide plate 85 and the mounting bracket 84, there are arrayed second dampers 851. Each second damper 851 has a spring on its exterior. One end of each second damper 851 is fixedly connected to the mounting bracket 84, and the other end is fixedly connected to the second guide plate 85.

One end of the third damper 861 is fixedly connected to the third guide plate 86, and the other end of the third damper 861 is fixedly connected to the mounting bracket 84. When the I-beam is inserted into the limiting block 8, the third guide plate 86 and the second guide plate 85 are squeezed and contracted. When the I-beam contacts the limiting block 8, it stops. The second push plate 74 is rotated so that the long side of the second push plate 74 is horizontal to the first push plate 73. The short side of the second push plate 74 is used to push and compress the I-beam. Figure 11 As shown, the second lifting plate 531 pushes the I-beam to adjust its height relative to the limit block 8.

[0058] This embodiment provides a support and protection method for building steel structures, including the following steps:

[0059] Select the appropriate limiting block 8 according to the vertical welded part to be clamped. When it is necessary to clamp square tubes or rectangular tubes, select the first guide plate 83. When it is necessary to clamp I-beams, select the second guide plate 85 and the third guide plate 86. After selection, fix the limiting block 8 in the rotating slot 61, and then install the vertical welded part into the limiting block 8. The second lifting plate 531 pushes the vertical welded part to adjust the height.

[0060] When welding is required on the lowest side of the vertical weldment, the vertical weldment is installed with the limiting block 8 for support and protection. The second clamping cylinder 75 drives the third connecting frame 71 to rotate and become horizontal with the second side frame 6. The second screw 72 is rotated to push the second push plate 74 to contact the vertical weldment and lock it. The horizontal weldment is placed on the third lifting plate 541 and the first lifting plate 331 for support. The third lifting plate 541 and the first lifting plate 331 adjust the height of the horizontal weldment relative to the vertical weldment. The third side frame 42 is rotated to close. The first screw 45 rotates to drive the first push block 441 forward to press the horizontal weldment. The fifth electric cylinder 55 pushes the vertical weldment forward to contact the horizontal weldment. Then the welding device performs welding. After welding is completed, the first clamping assembly 4 and the second clamping assembly 7 are moved back to unlock. The fifth electric cylinder 55 drives the entire weldment to move back and remove the entire weldment.

[0061] When multiple sets of transverse weldments need to be welded on the side of a vertical weldment, the positioning welding should be carried out sequentially from the top of the vertical weldment downwards. When the transverse weldment is long, insert plate 22 into slot 21 and place the transverse weldment on insert plate 22 at a specified height. Since the steel part is long, the two ends will hang down. The fourth lifting plate 621, the fifth lifting plate 631 or the fourth lifting plate 621 and the sixth lifting plate 641 make a fine adjustment of the height of the welding end. The first clamping assembly 4 and the second clamping assembly 7 lock the weldment. The fifth electric cylinder 55 pushes the vertical weldment forward to contact the transverse weldment, so that the contact surfaces of the two are perpendicular. Then the welding device performs welding. After the welding is completed, the first clamping assembly 4 and the second clamping assembly 7 move back to unlock. The fifth electric cylinder 55 drives the entire weldment to move back and remove the entire weldment.

[0062] When the welded part is tilted, change the connection method of the first push plate 73, the second push plate 74 and the second lead screw 72, unlock the rotating shaft 32, the first motor 35 drives the rotating shaft 32 and the first lifting plate 331 to rotate the angle, and then the second electric cylinder 33 pushes the first lifting plate 331 to rise, so that the first lifting plate 331 supports the tilted bottom of the transverse welded part. When the second push plate 74 and the first push block 441 contact the side of the transverse welded part, they rotate and fit together with their own tilted surfaces.

5. A support and protection method for a support and protection mechanism for a building steel structure according to claim 4, characterized in that, Includes the following steps: Select the appropriate limiting block (8) side according to the vertical welded parts to be clamped. When it is necessary to clamp square tubes or rectangular tubes, select the first guide plate (83). When it is necessary to clamp I-beams, select the second guide plate (85) and the third guide plate (86). After selection, fix the limiting block (8) in the rotating slot (61), and then install the vertical welded parts into the limiting block (8). The second lifting plate (531) pushes the vertical welded parts to adjust the height. When welding is required on the lowest side of the vertical weldment, the vertical weldment is installed with the limiting block (8) for support and protection. The second clamping cylinder (75) drives the third connecting frame (71) to rotate and be horizontal with the second side frame (6). The second screw (72) is rotated to push the second push plate (74) to contact the vertical weldment for locking. The horizontal weldment is placed on the third lifting plate (541) and the first lifting plate (331) for support. The third lifting plate (541) and the first lifting plate (331) adjust the height of the horizontal weldment relative to the vertical weldment. The third side frame (42) is rotated to close. The first screw (45) rotates to drive the first push block (441) to advance and squeeze the horizontal weldment. The fifth electric cylinder (55) pushes the vertical weldment forward to contact the horizontal weldment. Then the welding device performs welding. After welding is completed, the first clamping assembly (4) and the second clamping assembly (7) are pulled back to unlock. The fifth electric cylinder (55) drives the entire weldment to move back and remove the entire weldment. When multiple sets of transverse welding parts need to be welded on the side of the vertical welding part, the positioning welding should be carried out sequentially from the top of the vertical welding part downwards. When the transverse welding part is long, insert the insert plate (22) into the slot (21) and place the transverse welding part on the insert plate (22) at the specified height. Since the steel part is long, the two ends will hang down. The fourth lifting plate (621), the fifth lifting plate (631) or the fourth lifting plate (621) and the sixth lifting plate (641) make a fine adjustment of the height of the welding end. The first clamping component (4) and the second clamping component (7) lock the welding part. The fifth electric cylinder (55) pushes the vertical welding part forward to contact the transverse welding part so that the contact surfaces of the two are perpendicular. Then the welding device performs welding. After the welding is completed, the first clamping component (4) and the second clamping component (7) move back to unlock. The fifth electric cylinder (55) drives the entire welding part to move back and remove the entire welding part. When the welded part is tilted, change the connection method of the first push plate (73), the second push plate (74) and the second lead screw (72), unlock the rotating shaft (32), the first motor (35) drives the rotating shaft (32) and the first lifting plate (331) to rotate the angle, and then the second electric cylinder (33) pushes the first lifting plate (331) to rise, so that the first lifting plate (331) supports the tilted bottom of the transverse welded part, and the second push plate (74) and the first push block (441) rotate and fit together with their own tilted surfaces when they contact the side of the transverse welded part.
