Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to a heavy steel lifting tool. Background Art

[0002] With the continuous development of social economy and the increasing improvement of scientific and technological level, my country's forging industry is also booming. Lifting tooling, as a device for lifting steel materials to be forged, plays an important role in the forging industry.

[0003] However, the lifting tooling still has certain limitations during use. For example, the announcement number is, and its innovation lies in: including a crossbeam, a connecting block, a lifting rope, a connecting seat, a motor, a transmission shaft 1, a lifting drive mechanism 1, a sand box, a lifting drive mechanism 2 and a transmission shaft 2; the left and right sides of the crossbeam are fixedly connected with connecting blocks. The utility model has a reasonable and simple structure, low production cost, easy installation and complete functions. Here, the two sides of the lifting seat are lifted by lifting chains 1 and 2, thereby ensuring the balance of the tooling after lifting, and also avoiding the uncontrollable flipping or tilting of the sand box.

[0004] However, when lifting objects, the above application cannot lift objects of different sizes due to the relatively fixed ranges on both sides, resulting in a smaller lifting range of the entire tooling, thereby reducing the adaptability of use. Therefore, a heavy steel lifting tooling is proposed to solve the above problem. Utility Model Content

[0009] By adopting the above technical scheme, since the started servo motor can drive the driving block and the movable frame to move downward through the screw rod, the clamping block can be driven to move downward. When the clamping block moves downward, the clamping plate can be opened by the connecting rod so that the clamping block can pre-clamp the steel material. When the clamping block moves upward, the contracted clamping plate can push the telescopic rod to squeeze the clamping block and drive the fixed block on the clamping plate to press against the steel material, and fix the steel material together with the clamping block, thereby achieving the fixation of steel materials of different specifications and improving the stability of the steel material during fixed lifting.

[0018] Furthermore, the number of the clamping blocks and the number of the clamping plates are both two, the two clamping blocks and the two clamping plates are symmetrically distributed, and the lower end of the clamping block is J-shaped.

[0019] By adopting the above technical solution, the clamping block fixes the steel material on the inner side of the J-shaped end thereof.

[0020] Furthermore, the number of the fixing blocks is four, and the four fixing blocks are symmetrically distributed on the two clamping plates in groups of two.

[0021] By adopting the above technical solution, the pre-fixed steel material is further clamped and fixed by four fixing blocks.

When the clamping block moves downward, the clamping plate can be opened by the connecting rod to enable the clamping block to pre-clamp the steel material. When the clamping block moves upward, the contracted clamping plate can push the telescopic rod to squeeze the clamping block and drive the fixed block on the clamping plate to press against the steel material, thereby fixing the steel material together with the clamping block, thereby achieving the fixation of steel materials of different specifications and improving the stability of the steel material during fixed lifting.

[0032] A fixing member 4 is provided at the lower end of the support plate 1;

[0033] The fixing member 4 includes a servo motor 41, a support sleeve 42, a connecting rod 43, a screw rod 44, a telescopic rod 45, a clamping plate 46, a movable frame 47, a clamping block 48, a fixing block 49, a driving sleeve 410 and a driving block 411. The servo motor 41 is fixedly mounted on the lower end of the support plate 1, the screw rod 44 is fixedly connected to the output shaft of the servo motor 41, and the support sleeve 42 is fixedly connected to the lower end of the support plate 1 and is located on the outside of the servo motor 41.

[0034] The driving sleeve 410 is slidably connected to the inner side of the supporting sleeve 42. The supporting sleeve 42, the movable frame 47 and the driving sleeve 410 are all cylindrical. The outer side of the driving sleeve 410 is fixedly connected to a first slider having one end extending to the inside of the supporting sleeve 42. The inner wall of the supporting sleeve 42 is provided with a first slide groove located on the outer side of the first slider. The first slide groove is slidably connected to the first slider. The movable frame 47 is slidably connected to the inner side of the driving sleeve 410, so that the driving sleeve 410 can stably slide inside the supporting sleeve 42.

[0035] The outer side of the movable frame 47 is fixedly connected to a second slider having one end extending to the inside of the driving sleeve 410. The inner side of the driving sleeve 410 is provided with a second slide groove located outside the second slider. The second slide groove is slidably connected to the second slider, so that the movable frame 47 can stably slide up and down in the driving sleeve 410.

[0036] The driving block 411 is fixedly connected to the inner side of the movable frame 47 and is located on the outer side of the screw rod 44. The inner bottom wall of the movable frame 47 is provided with a round hole located on the outer side of the screw rod 44. The interior of the driving block 411 is provided with a threaded hole located on the outer side of the screw rod 44. The threaded hole cooperates with the thread on the outer side of the screw rod 44, so that the rotating screw rod 44 can drive the movable frame 47 to move up and down for adjustment through the driving block 411.

[0037] In this embodiment, since the driving sleeve 410 can stably slide inside the support sleeve 42, and the movable frame 47 can stably slide up and down in the driving sleeve 410, after the servo motor 41 is started and drives the screw 44 to rotate, the rotating screw 44 can drive the movable frame 47 to move up and down through the driving block 411, so that the movable frame 47 and the driving sleeve 410 can be telescopically moved in the support sleeve 42.

[0038] See also Figure 1-3 In this embodiment, the clamping plate 46 is hinged at the lower end of the support plate 1, the connecting rod 43 is hinged between the clamping plate 46 and the movable frame 47, and the inner walls of the support sleeve 42 and the driving sleeve 410 are both provided with grooves located on the outer side of the connecting rod 43, so that the connecting rod 43 hinged between the clamping plate 46 and the movable frame 47 has a moving space;

[0039] The clamp block 48 is hinged at the lower end of the movable frame 47. The number of the clamp block 48 and the clamp plate 46 are both two. The two clamp blocks 48 and the clamp plate 46 are symmetrically distributed. The lower end of the clamp block 48 is J-shaped, so that the J-shaped end of the clamp block 48 can initially fix the steel material inside thereof.

[0040] The telescopic rod 45 is hinged between the clamping plate 46 and the clamping block 48. The telescopic rod 45 is composed of a sleeve 451, a spring 452 and a slide bar 453. The slide bar 453 is slidably connected to the inner side of the sleeve 451. The spring 452 is fixedly connected between the end of the slide bar 453 and the inner side of the sleeve 451. One end of the slide bar 453 located outside the sleeve 451 is hinged to the clamping block 48. The end of the sleeve 451 is hinged to the inner side of the clamping plate 46, so that the squeezed telescopic rod 45 can be extended and retracted.

[0041] The fixing blocks 49 are fixedly connected to the inner side of the clamping plates 46 . There are four fixing blocks 49 . The four fixing blocks 49 are symmetrically distributed on the two clamping plates 46 in groups of two. The pre-fixed steel material is further clamped and fixed by the four fixing blocks 49 .

[0042] It should be noted that the lifting ring 3 is placed and fixed on the crane through conventional connection, which belongs to the existing conventional technical means, so this application will not elaborate on the installation method of the lifting ring.

[0043] The working principle of the above embodiment is:

[0044] Since the driving sleeve 410 can stably slide inside the supporting sleeve 42, and the movable frame 47 can stably slide up and down in the driving sleeve 410, after the started servo motor 41 drives the screw rod 44 to rotate, the rotating screw rod 44 can drive the movable frame 47 to move up and down through the driving block 411, so that the movable frame 47 and the driving sleeve 410 can move telescopically in the supporting sleeve 42. When the movable frame 47 moves downward for adjustment, the clamping block 48 can be driven to move downward, and when the clamping block 48 moves downward, the clamping block 48 can also be opened by the connecting rod 43. The plate 46 is used to pull the clamping block 48 to open through the telescopic rod 45, and after the clamping block 48 is hoisted to both sides of the steel material, the servo motor 41 can be started in reverse to pre-clamp the steel material through the contracted clamping block 48. When the clamping block 48 moves up, the contracted clamping plate 46 can push the telescopic rod 45 to squeeze the clamping block 48 and drive the fixing block 49 on the clamping plate 46 to resist the steel material, and fix the steel material together with the clamping block 48, thereby achieving the fixation of steel materials of different specifications and improving the stability of the steel material during fixed lifting.
