Description

Technical Field

[0001] The utility model belongs to the technical field of axle housings, and particularly relates to a turnover hanger for cleaning residual liquid in an inner cavity of axle housings. Background Art

[0002] Currently, conventional axle housing hoists utilize lifting rings to hold the shaft ends on both sides. Due to the heavy weight and high friction of the axle housing, it is difficult to flip the axle housing while it is being hoisted. This difficulty results in residual cutting fluid remaining in the axle housing cavity after machining being carried away with the axle housing, resulting in significant waste of cutting fluid. Furthermore, existing axle housing hoists lack versatility and are only suitable for axle housings with axle tubes at both ends. Furthermore, existing axle housing hoists are mostly made of hard steel, which makes the hoisting mechanism prone to collisions with the machined surfaces of the axle housing during hoisting.

This design converts the sliding friction between the axle housing and the lifting device during tilting into rolling friction, making it easier to flip the axle housing. When lifting a circular tubular axle housing, a ring of rubber-coated rollers contacts the axle housing shaft. When the axle housing is tilted, rolling friction is generated between the axle housing shaft and the rubber-coated rollers, enabling the axle housing to flip.

[0021] This utility model press-fits a cylindrical roller bearing onto a roller sleeve with rubber-coated rollers. When the square tube axle housing is hoisted, the square tube of the axle housing is clamped between a circle of rubber-coated rollers, securing the axle housing. When the axle housing is flipped, the cylindrical roller bearing drives the roller sleeve with rubber-coated rollers, creating rolling friction at the contact point with the axle housing, enabling the square tube axle housing to flip.

[0022] The utility model is designed with nylon lifting ring sleeves and roller sleeves, and the rollers are rubber-coated rollers. When the sling contacts the bridge housing, the rollers and the bridge housing are protected, which greatly increases the service life of the sling and reduces the occurrence of bridge housing quality problems.

[0034] The embodiment of the present application discloses a flip hanger for cleaning residual liquid in the inner cavity of an axle housing.

[0035] Example

[0036] according to Figures 1 to 8 As shown, a flip hoist for cleaning residual liquid in the inner cavity of a bridge housing includes a strong ring 1 and two ropes 2. The strong ring 1 is a 2T, G80 strong ring, and the rope 2 is a stainless steel wire rope 6×19S+FC-12mm. The upper end of each rope 2 passes through the strong ring 1, and the upper end of the rope 2 extends downward after passing through the strong ring 1. The upper end of the rope 2 is fixedly connected to the rope 2 itself through a pressing joint 10. The pressing joint 10 is made of aluminum alloy. The lower end of each rope 2 is wrapped with a lifting ring 3. The lower end of the rope 2 and the outer side of the lifting ring 3 are fixedly connected by a tightening joint 11. The tightening joint 11 fixes the lower end of the rope 2 to the rope 2 itself through a hexagonal cylindrical head screw 14 and a hexagonal nut 15. The lower end of the rope 2 is wrapped around the lifting ring 3 and extends upward, and the lower end of the rope 2 is fixedly connected to the rope 2 itself through the tightening joint 11.

[0037] The lifting ring 3 includes a lifting ring sleeve 4 and a cover plate 5. One side of the lifting ring sleeve 4 is open. The outer side of the lifting ring sleeve 4 is provided with a plurality of annular grooves 13 in parallel along the circumferential direction. The annular grooves 13 are used to place the rope 2, which is convenient for the rope 2 to be wrapped around and fixed to the lifting ring 3. The side of the lifting ring sleeve 4 with an opening is detachably connected to the cover plate 5 through a hexagon socket head screw 14. The lifting ring sleeve 4 and the cover plate 5 are provided with concentrically arranged through holes 12. The through holes 12 are used to be sleeved on both ends of the bridge housing. A cylindrical roller bearing 6 is installed inside the lifting ring sleeve 4.

[0038] The outer side of the cylindrical roller bearing 6 is fixedly connected to the inner side wall of the lifting ring sleeve 4, and the inner side of the cylindrical roller bearing 6 is fixedly connected with a roller sleeve 7. The outer side of the roller sleeve 7 is fixedly connected to the inner side of the cylindrical roller bearing 6. A roller pin 8 is installed on the inner side of the roller sleeve 7 along the circumferential direction. The roller pin 8 passes through the side wall of the roller sleeve 7. The outer side of the roller pin 8 is provided with a rubber-coated roller 9, and the rubber-coated roller 9 is distributed on the inner side of the roller sleeve 7 along the circumferential direction.

[0039] Working principle:

[0040] Install the entire sling and connect the force ring 1 to the crane. When the processing of the circular tube bridge shell 17 is completed, insert the two lifting rings 3 of the sling into the shaft heads at both ends of the circular tube bridge shell 17 so that the shaft heads are in contact with the rubber-coated rollers 9 designed in the sling. The operator operates the equipment to lift the circular tube bridge shell 17 while manually flipping the circular tube bridge shell 17. The rubber-coated rollers 9 rotate on the roller pins 8, and the friction between the circular tube bridge shell 17 and the rubber-coated rollers 9 is converted into rolling friction, which makes it easier for the operator to flip the circular tube bridge shell 17. After the circular tube bridge shell 17 is flipped, the cutting fluid in the inner cavity of the circular tube bridge shell 17 is poured into the processing equipment for recycling. After the dumping is completed, the circular tube bridge shell 17 is hoisted to the corresponding workstation equipment.

[0041] After the square tube bridge housing 16 is processed, the two lifting rings 3 of the lifting device are inserted into the square tubes at both ends of the bridge housing. At this time, the square tube of the bridge housing is stuck in the middle of the rubber-coated rollers 9, and the bridge housing is fixed. When the operator operates the equipment to lift the square tube bridge housing 16 while manually flipping the bridge housing, the cylindrical roller bearing 6 and the roller sleeve 7 are driven to convert into rolling friction, realizing the flipping of the square tube bridge housing 16, and pouring the cutting fluid in the inner cavity of the square tube bridge housing 16 into the processing equipment for recycling. After the dumping is completed, the square tube bridge housing 16 is hoisted to the corresponding work station equipment to complete the operation.
