[0001] The invention relates to the technical field of slings, in particular to a sling used for self-displacement of a front axle. Background Art

[0002] When the front axle is processed on the production line, it is sometimes necessary to flip the front axle 90° or 180°. During production, the front axle is usually lifted by a lifting device first, and then manually flipped when it falls. After processing, the previous steps are repeated to reset the front axle and place it on the production line. The operation is time-consuming and labor-intensive, and sometimes the space of the production line is small, and workers often need to squat or even climb down to operate, which is very inconvenient. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies of the prior art and to provide a lifting device for self-displacement of the front axle. The lifting device utilizes the process hole of the existing lightweight front axle and is provided with a lifting device that can be inserted into the process hole.

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0015] like Figure 1 As shown, a hanger for self-displacement of the front axle in this embodiment includes a base frame 1 which can be inserted into the process hole of the front axle, and a hanger 2 which forms an ∠ shape with the base frame 1, the base frame 1 is provided with a locking mechanism 3 to prevent the front axle from slipping; the locking mechanism 3 includes a round rod 31, the round rod 31 passes through the base frame 1 and can rotate and slide relative to the base frame 1, one end of the round rod 31 is fixed with an end plate 32 and is located on the outside of the insertion end of the base frame 1, the other end of the round rod 31 is fixed with a torsion plate 33 and is located on the outside of the lifting end of the base frame 1, and the round rod 31 is fixed with a locking plate 34 and is located in the middle of the insertion end and the lifting end of the base frame 1. Specifically, the suspension rod 21 of the hanger 2 is fixed to one end of the base frame 1, which is the lifting end, and the angle between the suspension rod 21 and the base frame 1 is 45°-90°. There are two suspension rods 21, and the tops of the two suspension rods 21 are penetrated by pins 22. The two ends of the pins 22 are locked by nuts, and the pins 22 are rotatably connected to a horseshoe-shaped lifting ring 23.

[0016] The present invention is mainly used for flipping the front axle with a process hole, and can also be used for flipping other workpieces with holes. During operation, the base frame 1 suspended by the lifting rope is inserted into the process hole of the front axle, and then the torsion plate 33 is rotated to 90° to make the locking plate 34 stand up. Because the height of the locking plate 34 after standing up is greater than the width of the process hole of the front axle, the front axle is prevented from sliding off the base frame 1 during lifting. In order to better lock the front axle, the locking plate 34 is set to a trapezoid in this embodiment. When lifting, the shorter end of the bottom side of the locking plate 34 is inserted into the process hole of the front axle in a wedge shape. At this time, the front axle is cross-locked and cannot move relative to the base frame 1. If the base frame 1 is inserted into the front axle process hole, the hanger 2 is on top, and the front axle can automatically flip 30°-60° under the action of gravity during lifting, and then the front axle can be flipped 90° with manual labor when falling; if the base frame 1 is inserted into the front axle process hole, the hanger 2 is on the bottom, and the front axle can automatically flip 120°-150° under the action of gravity during lifting, and then the front axle can be flipped 180° with manual labor when falling. The present invention utilizes the gravity of the front axle itself to flip a certain angle during lifting. Manual labor only needs to adjust the placement position of the front axle when it is placed on the ground, and then continue to loosen the sling. The front axle finds balance by itself under the action of gravity, thereby achieving the effect of flipping 90° or 180°. The lifting ring 23 is rotatably connected to the pin 22, which can facilitate the front axle and the sling to flip around the pin 22 during lifting.

[0017] In order to facilitate operation and prevent the lock plate 34 from rotating freely when the base frame 1 is inserted into the front axle process hole, causing the worker to be unable to insert the base frame 1 with one hand, affecting the work efficiency, the round rod 31 is sleeved with a spring 35, and the two ends of the spring 35 respectively resist the lifting end of the base frame 1 and the lock plate 34; the spring 35 is a compression spring. Under normal circumstances, the lock plate 34 presses the base frame 1 tightly under the resistance of the spring 35 and cannot rotate. After the base frame 1 is inserted into the front axle process hole, the worker pulls the torsion plate 33 to separate the lock plate 34 from the base frame 1, and rotates the torsion plate 33 to rotate the lock plate 34 90°, releases the torsion plate 33, and the lock plate 34 stands up and presses the base frame 1 again, so that the lock plate 34 is controlled and will not rotate under gravity or other external forces, causing accidental unhooking when lifting the front axle.

[0018] In order to further increase safety and prevent the locking plate 34 from rotating without human control, causing difficulty in operation when inserting into the base frame 1, or unhooking during lifting, a card plate 4 is provided on the inner side of the insertion end of the base frame 1. There are two card plates 4, which are respectively placed on the left and right sides of the round rod 31, and the minimum distance between the two card plates 4 is greater than the thickness of the locking plate 34.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
