Description

Technical Field

[0001] The utility model relates to the technical field of workpiece transportation, in particular to a hoisting tool for shaft forgings. Background Art

[0002] Axle forgings are generally in the shape of long axes. When the process is transferred during actual processing, due to their large size and heavy weight, it is not only difficult to transport them in the forging workshop by manpower but also very dangerous. Therefore, most workshops require a crane equipped with corresponding lifting tools for handling. For example, the prior art: CN205170170U, a lifting tool for shaft forgings, which includes a hook seat with a hanging hole for use with a crane, the lower part of the hook seat is connected to a horizontal hanger through a hanger rod, the hanger is provided with at least two lower-hanging hanger plates which can be moved and positioned on both sides of the hanger, and a hanging ring hole is provided on the lower-hanging hanger plate; the hook seat is a triangular beam seat structure with a hanging hole provided horizontally in the middle; the two ends of the hanger are provided with upward protrusions, and form a mountain-shaped hook body with the hanger rod; the lower ends of the lower-hanging hanger plates are respectively provided with circular connecting blocks, and the circular connecting blocks are provided with hanging ring holes.

[0003] There is also existing technology:

[0004] CN218927473U, a new multifunctional lifting device;

[0005] CN219971586U, a lifting tool for medium and large bearing forgings.

[0006] The above-mentioned prior art mentions a kind of lifting tool for shaft forgings. When lifting long shaft forgings, the forgings are usually placed flat on the bottom surface and fixed only at a single position. During the lifting, the forgings will change direction, and collisions and damages to the forgings are likely to occur during lifting and lowering. In addition, the single position fixation makes it easy for the forgings to deform during the lifting process, and the deformation of the forgings will cause dimensional errors.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: See Figure 1 The utility model provides a technical solution: a lifting tool for shaft forgings.

[0024] Among them, an inner groove is opened horizontally through the inside of the lifting frame 1; a center baffle 11 is fixedly connected to the center position of the inner groove, and lifting sliders 2 are arranged on both sides of the center baffle 11. A threaded hole 6 is opened in the center of the lifting slider 2, and an adjusting screw 4 is horizontally rotatably installed in the threaded hole 6, and a hook 12 is rotatably installed at the bottom of the lifting slider 2.

[0025] In this embodiment, the adjusting screw 4 passes through the threaded hole 6 on the lifting slider 2. By rotating the adjusting screw 4, the lifting slider 2 is moved in the inner groove, and the distance between the lifting sliders 2 is adjusted to ensure that the lifting slider 2 is aligned with one end of the forging. The hook 12 at the bottom is screwed into the lifting slider 2 through a thread, and a rope is passed through the hook 12 to fix the forging. In this way, the two lifting sliders 2 are fixed to the two ends of the forging through the rope on the hook 12, and the forging can be transported by lifting the lifting frame.

[0026] Among them, a crossbeam 7 is arranged between the center baffle 11 and the end plate 3, a support plate 9 is arranged at the bottom of the inner groove near the bottom of the lifting frame, a crossbeam groove 8 is opened at the center position of the bottom of the lifting slider 2, and support plate grooves 10 are opened on the left and right sides of the lifting slider 2.

[0027] In this embodiment, the support plate 9 is inserted into the support plate groove 10 of the lifting slider 2, the crossbeam 7 is embedded in the crossbeam groove 8, and the crossbeam 7 is connected to the center baffle 11, cooperating with the support plate 9 to lift the lifting slider 2 to prevent it from falling.

[0028] The adjusting screw rod 4 is a double-headed screw rod, and a rotating handle 5 is provided at the other end of the adjusting screw rod 4 .

[0029] In this embodiment, the double-headed screw means that the thread directions at both ends of the adjusting screw 4 are opposite. By engaging with the threaded holes 6 with the same thread direction at two places, the movement direction of the lifting slider 2 is opposite, and the distance between the two lifting sliders 2 becomes larger or smaller. The hook 12 under the lifting slider 2 is aligned with one end of forgings of various lengths. In this way, shaft forgings of any length can be lifted. The operator holds the rotating handle 5 and rotates it to rotate the adjusting screw 4, which is more labor-saving.

[0030] A hook 12 is provided at the bottom of the central baffle 11 .

[0031] In this embodiment, the hook 12 at the center baffle 11 is used to fix the center waist position of the forging, and plays a supporting role in the middle position to prevent the entire forging from being subjected to force at both ends when it is lifted, and the center position from falling and deforming.

[0032] A mounting hole 13 is provided on the top of the hanging bracket 1 .

[0033] In this embodiment, the mounting hole 13 on the top is used to fix it on a crane, and the crane is driven by an operator to move the hoisting frame 1 on the track, and finally drives the forging to move.

[0034] Wherein, end plates 3 are installed at both ends of the inner tank.

[0035] In this embodiment, the end plate 3 blocks the inner groove, which facilitates the installation and protection of the lifting slider 2.

[0036] Working principle: The lifting frame 1 is installed on the crane through the mounting hole 13, the lifting slider 2 is inserted into the inner groove, and the adjusting screw 4 passes through the threaded hole 6 on the lifting slider 2 to ensure that the two lifting sliders 2 are in contact with the center baffle 11. The two ends are fixed by the end plate 3. Hooks 12 are installed at the bottom of the center baffle 11 and the lifting slider 2, and ropes are passed through. By turning the handle 5, the adjusting screw 4 is rotated to adjust the distance between the two lifting sliders 2 and the center baffle 11 until they are aligned with the two ends of the forging. After being fixed with ropes, the hooks 12 under the center baffle 11 also need to be fixed with ropes. Finally, the crane lifts the lifting frame 1 to transport the forging.
