[0034] See also Figure 1-Figure 4The utility model provides a leaf spring assembly hanger tooling. In practical application, in order to solve the problem that the existing hanger tooling is easy to cause the leaf spring assembly to slide and fall after being hoisted during the hoisting process of the leaf spring assembly, the utility model comprises a hanger ring 1, two hangers 2 and two limit assemblies 3. The hanger ring 1 is a square closed frame structure formed by bending a bar. Two hangers 11 are arranged at the bottom end of the hanger ring 1. The hangers 11 are used to hang the leaf spring assembly 4. The two hangers 11 are respectively arranged on both sides of the hanger ring 1, and the two hangers 11 are fixedly connected to the hanger ring 1, that is, the two hangers 11 are fixedly connected to the two sides of the hanger ring 1 with shorter length. Among them, the top end of the suspension rod 11 is connected to the bottom end of the hanger ring 1, and a placement rod 12 is provided at the bottom end of the two suspension rods 11. The placement rod 12 and the suspension rod 11 are an integrally formed structure to increase the force strength of the suspension rod 11. A stabilizing rod 121 is also provided between the two placement rods 12, and the two ends of the stabilizing rod 121 are respectively fixedly connected to the two placement rods 12 to improve the stability of the placement rod 12. The placement rod 12 is a U-shaped hook structure formed by bending a rod to the longer side of the hanger ring 1 and then bending upward. The placement rod 12 is used to place the leaf spring assembly 4 during lifting. The two lifting buckles 2 are arranged on the hanger ring 1 away from the hanger rod 11, and the two lifting buckles 2 are parallel to each other at the hanger ring 1 away from the hanger rod 11. The two lifting buckles 2 are jointly arranged on the longer side of the hanger ring 1. The lifting buckle 2 is used to be connected to the crane to realize the connection between the lifting tool and the crane, and the position of the lifting buckle 2 corresponds to the position of the placement rod 12, that is, the position of the lifting buckle 2 on the hanger ring 1 is on the same side as the position of the leaf spring assembly 4 placed in the placement rod 12. At the same time, when the leaf spring assembly 4 is lifted, the position of the lifting buckle 2 is consistent with the center of gravity line when the lifting tool lifts the leaf spring assembly 4, so as to prevent the lifting tool from swinging excessively and ensure stability during lifting. The two limiting components 3 are respectively arranged on the two hanging rods 11, and the limiting components 3 can slide on the hanging rods 11 with the hanging rods 11 as the axis. The two limiting components 3 are respectively located above the two placing rods 12. The limiting components 3 are used to cooperate with the placing rods 12 to limit the leaf spring assembly 4 as a whole. The limiting components 3 cooperate with the placing rods 12 to achieve the limiting and fixing of the hoisted leaf spring assembly 4 to prevent the leaf spring assembly 4 from sliding and falling during hoisting. In this embodiment, when in use, the staff first lifts the limit assembly 3 to a certain height so that there is a certain distance between the limit assembly 3 and the placement rod 12, and then places the leaf spring assembly 4 flat on the upper ends of the two placement rods 12. At this time, the limit assembly 3 is released, so that the limit assembly 3 slides to the upper end of the leaf spring assembly 4 and abuts against it. Under the cooperation of the limit assembly 3 and the placement rod 12, the leaf spring assembly 4 is firmly clamped and limited, so as to fix the position of the leaf spring assembly 4 during lifting and prevent the leaf spring assembly 4 from slipping.That is, the problem in the prior art that the lifting ring easily causes the leaf spring assembly 4 to slide and fall during the lifting process is effectively solved.

[0035] In some embodiments, in order to facilitate the description of the hook 2, one hook 2 is used for illustration, and the hook 2 includes a sleeve 21 and a connector 22. The sleeve 21 is arranged at the longer end of the hanger ring 1 and is close to the bend of the hanger ring 1, that is, the sleeve 21 is arranged on the hanger ring 1 and corresponds to the position of the placement rod 12. The sleeve 21 is movably connected to the hanger ring 1 so that the hook 2 can rotate on the hanger ring 1, thereby ensuring that the leaf spring assembly 4 can adjust the position of the sling tooling during hoisting, so that the sling tooling can maintain a balanced state. The connector 22 is fixedly arranged on the sleeve 21, and a through hole 221 is opened in the connector 22. The through hole 221 is used to cooperate with the hook or hanging rope on the crane to realize the connection between the crane and the sling tooling.

[0036] In some embodiments, in order to facilitate the description of the limiting assembly 3, one limiting assembly 3 is used for description, and the limiting assembly 3 includes a sliding sleeve 31, a pressure rod 32 and an elastic member 33. The sliding sleeve 31 is arranged on the suspension rod 11 and is movably connected to the suspension rod 11, and an abutment plate 311 is arranged at one end of the sliding sleeve 31 close to the hanger ring 1. The pressure rod 32 is arranged in an L shape, and the pressure rod 32 is fixedly arranged on the sliding sleeve 31, and the pressure rod 32 corresponds to the placement rod 12, that is, one end of the pressure rod 32 is fixedly connected to the sliding sleeve 31, and the pressure rod 32 extends in a direction parallel to the placement rod 12, and its end is bent downward to form an L-shaped structure. The elastic member 33 is arranged on the suspension rod 11, one end of the elastic member 33 is assembled at the connection between the suspension rod 11 and the hanger ring 1, and the other end is fixedly assembled at the upper end of the abutment plate 311, and the abutment plate 311 is used to increase the contact surface between the sliding sleeve 31 and the elastic member 33, increase the bearing capacity of the elastic member 33, and prevent the sliding sleeve 31 from sliding randomly through the elastic force of the elastic member 33, and at the same time, a certain pressure can be applied to the sliding sleeve 31, so that the pressure rod 32 fixedly connected to the sliding sleeve 31 can restrict and fix the leaf spring assembly 4 during the hoisting, and prevent the leaf spring assembly 4 from sliding. Preferably, a connecting rod 34 is arranged between the sliding sleeves 31, and the two ends of the connecting rod 34 are respectively fixedly connected to the side surfaces of the two sliding sleeves 31, so that the two sliding sleeves 31 can slide synchronously, and can prevent the two sliding sleeves 31 from rotating, thereby ensuring that the two pressure rods 32 will not deviate. Preferably, the elastic member 33 is a coil spring, which can be evenly sleeved on the suspension rod 11 without interfering with the sliding of the sleeve 31 on the suspension rod 11. The coil spring is lightweight and convenient for timely replacement and maintenance. The coil spring is not easily compressed under normal conditions, so that the pressure rod 32 is always in contact with the placement rod 12 when the leaf spring assembly 4 is not placed on the placement rod 12.

[0037] In some embodiments, the suspension rod 11 is welded to the lower end of the hanger ring 1. To ensure the firmness of the welding, a reinforcing rib 111 is further provided at the connection between the suspension rod 11 and the hanger ring 1. The reinforcing rib 111 can improve the rigidity and strength of the connection between the suspension rod 11 and the hanger ring 1, and prevent the suspension rod 11 from twisting and deforming due to uneven stress.

[0038] In some embodiments, a separation rod 23 is also provided on the hanger ring 1. The separation rod 23 is arranged between the two hooks 2. The separation rod 23 is used to adjust the distance between the two hooks 2 and fix the position of the hook 2 on the hanger ring 1 to prevent the hook 2 from sliding on the hanger ring 1, so as to improve the stability of the leaf spring assembly 4 during lifting.
