Description

Technical Field

[0001] The present application relates to the technical field of cranes, and in particular to a lifting fixture for processing steel structural parts. Background Art

[0002] With the continuous development of modern industry, steel structures are widely used in various engineering projects. From bridges, highways to buildings, the role of steel structures cannot be ignored. Correspondingly, the market for steel structure processing is also booming. When transferring or lifting some steel structures, lifting and hoisting devices are required. In the processing of large steel structures, heavy lifting devices are usually used to transfer steel structures. Generally, lifting and hoisting devices mainly rely on lifting clamps for clamping and transfer, and then rely on ropes and lifting arms to lift the steel structures. Although the existing technology has made certain progress, there are still many shortcomings.

[0003] The existing technology still has the following problems:

[0004] 1. During the lifting and transfer process of the steel structure clamped by the clamp, the movement of the crane arm will drive the movement of the rope on the crane arm, and the movement of the rope will affect the hoisted steel structure. After hoisting to the appropriate position and lowering it, the rope is in a swinging process for a long time, resulting in a long waiting time for stillness, affecting the lifting efficiency. If the hoisted steel structure is lowered directly, the position of the hoisted steel structure will deviate, and it is easy to injure the staff when the steel structure swings, causing dangerous accidents.

[0005] 2. The crane's boom cannot adjust the position of the steel structure during lifting. The steel structure rotates during the clamp lifting process, and manual adjustment at a later stage wastes time, resulting in the placement of the steel structure during processing affecting the processing efficiency.

[0006] 3. The existing clamps have poor stability and cannot be properly adjusted according to the size of the steel structure, which makes it easy for the steel structure to tilt when clamping it. In addition, the existing clamps require manual auxiliary clamping when operating, such as releasing the limit of the clamp and prying open the clamp arm. Summary of the invention

[0018] The technical solution provided by this application has at least the following technical effects or advantages:

[0019] 1. The use of the correction component effectively solves the problem that during the lifting and transfer process of the steel structure clamped by the clamp, the movement of the crane arm will drive the movement of the rope on the crane arm, and the movement of the rope will affect the hoisted steel structure. After the steel structure is lifted to a suitable position and lowered, the rope is in a swinging process for a long time, resulting in a long waiting time for stillness, affecting the lifting efficiency. If the steel structure is directly lowered, the position of the steel structure will deviate, and the staff may be easily injured when the steel structure swings, causing dangerous accidents. The present invention can reduce the swing amplitude of the rope during the lifting process through the correction component, so that it can quickly stop when it is lifted to a suitable position, thereby improving the lifting efficiency and making the lifting position more accurate.

[0020] 2. The use of a rotating assembly effectively solves the problem that the crane's boom cannot adjust the position of the steel structure during lifting. The steel structure rotates during the clamp lifting process, and manual adjustment in the later stage wastes time, resulting in the placement of the steel structure during processing affecting the processing efficiency. The present invention can adjust the position of the steel structure through the rotating assembly, avoiding the waste of time in manual adjustment in the later stage.

[0021] 3. The use of the clamp assembly effectively solves the problem that the existing clamps have poor stability and cannot be properly adjusted according to the size of the steel structure, which makes it easy for the steel structure to tilt when clamping it. In addition, the existing clamps require manual auxiliary clamping of the clamps during operation, such as releasing the limit of the clamp and prying open the clamp arms. The present invention can make appropriate adjustments according to the size of the steel structure through the clamp assembly, thereby increasing the stability of the clamped steel structure, and there is no need to manually pry open the clamp arms for auxiliary clamping, and the clamp arms can be opened during clamping.

[0040] See also Figure 4 , Figure 6 and Figure 7As shown, the correction component 6 includes a first correction mechanism 61, a second correction mechanism 62 is arranged on the outer surface of the first correction mechanism 61, a limiting mechanism 63 is arranged on the side of the second correction mechanism 62 away from the first correction mechanism 61, there are two correction components 6, one of which is fixed on the inner arm of the machine arm 4, and the other is slidably connected with the adjustment component 7, the first correction mechanism 61 includes a connecting seat 611, a first slider 612 is fixedly installed on the outer surface of the connecting seat 611, a limiting block 613 is fixedly installed in the inner cavity of the first slider 612, and a first slide rod 614 is slidably connected to the inner cavity of the first slider 612, so that the first slider 612 is always in a straight line when the first slide rod 614 slides, and the two ends of the first slider 612 A first spring 615 is arranged on the side, and the first spring 615 is sleeved with the first sliding rod 614. The second correction mechanism 62 includes a connecting sleeve 621, and the connecting sleeve 621 is fixedly connected to the connecting seat 611. The inner cavity of the connecting sleeve 621 is slidably connected with a slide plate 622. A limiting rod 623 is fixedly installed on the side of the slide plate 622 close to the connecting sleeve 621. The outer surface of the limiting rod 623 is sleeved with a second spring 624. One end of the second spring 624 is fixedly connected to the slide plate 622, and the other end is fixedly connected to the inner wall of the connecting sleeve 621. The end of the connecting sleeve 621 away from the connecting seat 611 is fixedly installed with a first fixed block 625. The inner cavity of the first fixed block 625 is rotatably connected with a correction frame 626. The correction frame Correction wheels 627 are provided on both sides of 626, and the correction wheels 627 are fitted with the slide plate 622. When the steel structure is hoisted, the rope 3 is placed between the first clamping ring 633 and the second clamping ring 635. During the hoisting process, the rope 3 will shake with the swing of the machine arm 4, thereby causing the steel structure to shake during the hoisting process, which is easy to cause safety accidents and reduces the hoisting efficiency. After the rope 3 is restricted by the limiting mechanism 63, when the rope 3 swings left and right, the limiting mechanism 63 drives the second correction mechanism 62 to move left and right, and the second correction mechanism 62 drives the first correction mechanism 61 to move left and right, that is, the connecting seat 611 drives the first slide block 612 to slide in the inner cavity of the first slide bar 614. When the rope 3 is moved, the elastic force of the first spring 615 causes the first slider 612 to return to the middle position, thereby preventing the rope 3 from deviating to the left or right. When the rope 3 swings in other directions, the limiting mechanism 63 drives the correction frame 626 to rotate in the inner cavity of the first fixed block 625. At this time, one end of the correction wheel 627 squeezes the slide plate 622, causing the slide plate 622 to slide in the inner cavity of the connecting sleeve 621. At this time, the elastic force generated by the second spring 624 causes the correction wheel 627 to return to its original position, so that the position of the rope 3 can be quickly corrected, ensuring that the shaking amplitude of the steel structure during the lifting process is reduced, preventing the swing amplitude from being too large to injure the staff, and being able to quickly stop during the lifting process to improve the processing efficiency.

The rope 3 is placed between the first clamping ring 633 and the second clamping ring 635. When the thickness of the rope 3 changes, the distance between the first clamping ring 633 and the second clamping ring 635 can be adjusted to adapt to ropes 3 of different thicknesses. The second slider 632 is driven to slide on the first threaded rod 631 by rotating the first threaded rod 631.

The movement of the adjustment plate 9110 drives the pitch adjustment rod 919 to move in the inner cavity of the pitch adjustment groove 9111. The movement of the pitch adjustment rod 919 drives the pitch adjustment seat 918 to move on the sliding frame 917. In the process of the distance adjustment seat 918 moving relative to each other,The second set of rods 928 and the second telescopic rod 929 move relative to each other, and cooperate with the distance adjusting seat 918 to approach each other, thereby driving the two clamping mechanisms 92 to approach each other, so as to adjust the distance of the clamping mechanisms 92 according to the length of the steel structure, and ensure the stability of the steel structure during the clamping process.

Rod 939, the top of the second connecting rod 939 is fixedly installed with a second clamping ring 9310, the first clamping ring 938 and the second connecting rod 939 are slidably connected, the first clamping ring 938 and the second clamping ring 9310 are of the same shape and size, and are in opposite directions, the side of the clamping block 934 close to the second connecting rod 939 is an inclined surface, and the bottom side of the clamping block 934 is narrower, which is convenient for clamping with the second clamping ring 9310. When clamping the steel structure, the first clamping arm 924 and the second clamping arm 925 can maintain a large distance, which is convenient for the steel structure to pass through the support block 9210 during the clamping process, and when lifting, the first clamping arm 924 and the second clamping arm 925 are close to each other, and the steel structure is tightly clamped. The clamping mechanism 924 is in the absence of external force. When lifted, the first clamping arm 924 and the second clamping arm 925 can clamp the object, but manual assistance is required to open the first clamping arm 924 and the second clamping arm 925 during clamping. The clamping block 934 and the second clamping ring 9310 can drive the distance between the fixing rod 931 and the second fixing block 936 to remain fixed, drive the fixation of the second set rod 928 and the second telescopic rod 929, so that the crossing angle between the second connecting rod 922 is fixed, so that the clamping mechanism 92 can clamp, and the downward movement of the fixing rod 931 drives the collection and release disk 932 to move downward, and the downward movement of the collection and release disk 932 drives the pressure rod 933 to move downward, and the downward movement of the pressure rod 933 drives the clamping block 934 to move downward. At this time, the fourth spring 935 contracts and the pressure rod 933 is stored to The inner cavity of the receiving and releasing disk 932 is moved down until the block 934 moves to the bottom end of the first clamping ring 938, and the block 934 fits with the outer surface of the first clamping ring 938 under the elastic force of the fourth spring 935. When the fixing rod 931 moves up, it drives the first clamping ring 938 to move up until the first clamping ring 938 and the second clamping ring 9310 fit tightly. During the movement, the receiving and releasing disk 932 drives the block 934 to directly pass through the second clamping ring 9310. At this time, the second set of rods 928 are freed from the restraint of the receiving and releasing disk 932, so that the clamping mechanism 92 can clamp the steel structure during the rising process without manual assistance, that is, by controlling the clamping block 934 and the second clamping ring 9310 to engage, and using the first clamping ring 938 to cooperate and disengage to release the restraint of the second set of rods 928.

[0046] In summary, the steel structure is clamped and transported by the clamp assembly 9, the rotating assembly 8 is used to adjust the direction of the steel structure, the correction assembly 6 is used to control the offset of the rope 3, and the adjustment assembly 7 is used to control the position of the lower correction assembly 6. When the steel structure is hoisted, the rope 3 is placed between the first clamping ring 633 and the second clamping ring 635. During the hoisting process, the rope 3 will shake with the swing of the machine arm 4. After the rope 3 is restricted by the limiting mechanism 63, when the rope 3 swings left and right, the connecting seat 611 drives the first slider 612 to slide in the inner cavity of the first slide rod 614. At this time, the elastic force of the first spring 615 causes the first slider 612 to return to the middle position, thereby To prevent the rope 3 from deviating to the left or right, when the rope 3 swings in other directions, the elastic force generated by the second spring 624 restores the correction wheel 627 to its original position, so that the position of the rope 3 can be quickly corrected. The distance between the first clamping ring 633 and the second clamping ring 635 can be adjusted to adapt to ropes 3 of different thicknesses. The second slider 632 is driven to slide on the first threaded rod 631 by rotating the first threaded rod 631. At this time, the second slider 632 moves toward or away from each other, thereby changing the distance between the first clamping ring 633 and the second clamping ring 635. The connecting strip 78 is pulled to drive the pull rod 77 to move in the inner cavity of the slide seat 76, so as to adjust the position of the correction component 6 on the adjustment bracket 74. The position of the correction component 6 is adjusted according to the needs, so that the connection between the hanging ring 73 and the hook 5 is more stable. The gear 81 and the rotating rod 72 are driven by the operation of the cylinder 83 to rotate around the bottom end of the connecting plate 71, thereby driving the clamp assembly 9 to rotate to adjust the position of the steel structure. The distance adjusting seat 918 is driven to move on the sliding frame 917 by the operation of the motor 913. In the process of the distance adjusting seat 918 moving relative to each other, the second set of rods 928 and the second telescopic rod 929 move relative to each other, and cooperate with the distance adjusting seat 918 to approach each other, thereby driving the two clamping mechanisms 92 to approach each other, so as to adjust the distance of the clamping mechanism 92 according to the length of the steel structure, and ensure that the steel structure is clamped. To ensure the stability of the process, the downward movement of the fixing rod 931 drives the block 934 to move downward. At this time, the fourth spring 935 contracts, and the pressure rod 933 is received in the inner cavity of the storage disk 932 until the block 934 moves down to the bottom end of the first clamping ring 938. Under the elastic force of the fourth spring 935, the block 934 fits with the outer surface of the first clamping ring 938. When the fixing rod 931 moves upward, it drives the first clamping ring 938 to move upward until the first clamping ring 938 and the second clamping ring 9310 fit tightly. During the movement, the storage disk 932 drives the block 934 to directly pass through the second clamping ring 9310. At this time, the second set of rods 928 removes the restraint of the storage disk 932, so that the clamping mechanism 92 clamps the steel structure during the rising process.
