When the bogie is hoisted, the two wheel pairs are simultaneously lifted and stressed, the bogie is stable and free of moving inclination, the stress state of parts is the same as that of the parts when the bogie travels on a track, the problems of inclination deformation and abnormal stress when the bogie is hoisted can be effectively solved, and potential quality hazards are eliminated. By replacing the cross beams, the longitudinal beams and the lifting hooks with different design sizes, the device can be suitable for bogies of various different vehicle types.

Description

Technical Field

[0001] The utility model relates to the field of railway vehicle manufacturing, in particular to a bogie hanger. Background Art

[0002] In the process of producing a certain type of railway freight car bogie, after the bogie is assembled and inspected, if it cannot be transferred to the next process through the track, it needs to be suspended by the bogie integral sling. Currently, two lifting belts are used, and the two ends are hung on the bearing parts on both sides of the bogie and hang up on the two ends of the bolster. After the overhead crane is raised, the lifting belt locks the bogie and then lifts it. Its shortcomings are: the slings used in the prior art are two lifting belts, and two operators hang the lifting belts on the bearing parts at both ends of the bogie at the same time during the lifting. Since the lifting belts on both sides cannot be completely aligned when hanging, and cannot be automatically aligned during lifting, the bogie is in a tilted state in most cases during lifting, causing some parts of the bogie, especially the cross support device, to always be in an abnormal stress state during lifting, which seriously affects the product quality of the bogie after inspection and has great quality risks. Utility Model Content

[0003] The utility model aims to provide a railway freight car bogie hoist, which can make two wheel sets lift and bear force at the same time when the bogie is hoisted, the bogie is stable without moving or tilting, the stress state of parts and components is the same as when they are running on the track, and can effectively solve the problems of tilting deformation and abnormal stress during bogie hoisting and eliminate quality risks.

[0004] The utility model mainly comprises a crossbeam, a longitudinal beam, a lifting hook, a lifting ring and a movable connecting piece.

[0005] The middle of the cross beam is provided with a through hole, and the lifting ring is connected to the cross beam through the through hole. The two ends of the cross beam pass through the middle of the longitudinal beam respectively and are connected through a movable connecting piece. The two ends of each longitudinal beam pass through the lifting hook respectively and are connected through a movable connecting piece.

[0006] Preferably, rubber plates are provided on both the inner and outer surfaces of the hook end of the hook to prevent the paint of the wheelset axle from being damaged when the hook contacts the wheelset axle. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Example 1

[0013] exist Figure 1-Figure 4 In the schematic diagram of the utility model shown, a railway freight car bogie hanger mainly includes a crossbeam, a longitudinal beam, a hook, a lifting ring and a movable connecting piece. The crossbeam includes a crossbeam body 1 and a crossbeam connecting block 2. The crossbeam body is trapezoidal. Upward-inclined crossbeam connecting blocks are respectively provided at both ends of the crossbeam, and through holes are opened on the crossbeam connecting blocks. The lifting ring includes a circular lifting ring 3 and a duckbill lifting ring 4. Two through holes are opened in the middle of the crossbeam body. The two duckbill lifting rings are installed in coordination with the through holes in the middle of the crossbeam body. Bolts pass through the duckbill lifting rings and the through holes in the middle of the crossbeam body and are fixed by nuts. The circular lifting ring is sleeved on the duckbill lifting ring. The longitudinal beam includes a longitudinal beam body 5 and a longitudinal beam connecting block 6. The longitudinal beam body is trapezoidal. Upward-inclined longitudinal beam connecting blocks are respectively provided at both ends of the longitudinal beam, and through holes are opened on the longitudinal beam connecting blocks. A through hole is provided in the middle of the longitudinal beam, and the two cross beam connection blocks are respectively inserted into the through holes in the middle of the two longitudinal beams, and the movable connection piece 7 is inserted into the through hole of the cross beam connection block to prevent the longitudinal beam from moving. Each longitudinal beam connection block passes through the through hole on the hook 8, and the movable connection piece is inserted into the through hole of the longitudinal beam connection block to prevent the hook from moving. Rubber plates 9 are provided on the inner and outer surfaces of the hook end of the hook to prevent the hook from damaging the paint of the axle body when it contacts the wheelset axle body. The movable connection piece can be a round pin.

[0014] During use of the utility model, the crane hook head is hung on the lifting ring, the lifting device is moved to the position of the bogie, and the operator fine-tunes the state of the lifting device so that the arc part of the hook end contacts the lower part of the bogie wheel pair axle body, and after confirmation, the lifting device is stably lifted and transported.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] (1) When the bogie is hoisted, the two wheelsets are lifted and stressed at the same time, and the bogie is stable without movement or tilting. The stress state of the components is the same as when the track is running, which can effectively solve the problem of tilt deformation and abnormal stress during bogie hoisting and eliminate quality risks.

[0017] (2) By replacing the cross beams, longitudinal beams and hooks of different design sizes, it can be applied to bogies of various models.
