Description

Technical Field

[0001] This invention provides a transport fixture for cold-rolled steel sheet production, belonging to the field of cold-rolled steel sheet transportation. Background Technology

[0002] The initial design of the overhead crane wheels in the cold-rolled steel mill's post-rolling warehouse used tapered roller bearings. After one or two months of use, the bearings would come loose, causing them to break through the wheel end caps and potentially fall from a height. The original tapered roller bearings bore significant axial forces, and their fixation relied entirely on the fastening of coaxial couplings. If these couplings loosened, the bearings would move outwards, causing the wheel to bite against the rails and the bearings to shift, potentially breaking through the end caps or even falling to the ground. This severely impacted the safe and stable operation of the crane. Furthermore, the lack of adequate cushioning at the wheels resulted in excessive pressure on them, reducing their lifespan. Summary of the Invention

[0003] This invention provides a transport fixture for cold-rolled steel sheet production, and a wheel bearing mounting structure that makes vehicle operation safer and more reliable.

[0004] The present invention discloses a transport fixture for cold-rolled steel sheet production, which is implemented as follows: The transport fixture for cold-rolled steel sheet production includes a connecting frame structure. An installation groove is provided on one side of the connecting frame structure, and a track wheel structure is provided in the installation groove. The track wheel structure includes an upper arc-shaped clamping plate and a lower arc-shaped clamping plate. A rolling shaft is clamped between the upper and lower arc-shaped clamping plates. A cylindrical roller bearing is fitted on the outer side of one end of the rolling shaft. A track wheel is fitted on the outer side of the cylindrical roller bearing. A slotted roller is fixed on the outer side of the track wheel. A bearing sealing cover is provided on one side of the track wheel, and the bearing sealing cover is fixed to one side of the track wheel by several fastening bolts.

[0005] The mounting groove has a groove on its upper side, and a limiting ring groove is formed outside the groove. A deep groove is formed on both sides of the limiting ring groove on the upper side of the mounting groove, and a damping rod is fixed on the upper side of the deep groove to absorb impact.

[0006] A limiting post is fixed at the groove on the upper side of the upper arc-shaped clamping plate, and a limiting cylinder is fixed at the limiting ring groove on the upper side of the upper arc-shaped clamping plate. The bottom end of the damping rod is fixed on the upper side of the upper arc-shaped clamping plate. The limiting post and the limiting cylinder are respectively inserted into the groove and the limiting ring groove. A rigid spring is fixed between the upper side of the limiting post and the upper side of the groove.

[0007] The upper arc-shaped clamping plate and the lower arc-shaped clamping plate are fixedly connected by bolts, which facilitates the restriction of the position of the rolling shaft.

[0008] The bottom of the connecting frame structure is fixed with a steel cable traction frame for hanging steel plates, and a drive motor is fixed on one side of the steel cable traction frame.

[0009] The aforementioned fastening bolts, totaling eight, ensure a more secure bearing seal and prevent it from falling off.

[0010] Limiting plates are fixed on both sides of the upper and lower arc-shaped clamping plates inside the mounting groove.

[0011] The drive motor is electrically connected to an external power source.

[0012] The advantage of this invention is that by adding a shock-absorbing structure, the rigid spring and damping rod can play a certain buffering role when loading steel plates during the transportation process of the trolley, thereby reducing damage to the track wheels. By replacing the cylindrical roller bearings, the service life of the track wheels is increased. Attached Figure Description

[0020] The invention will be further described below with reference to the accompanying drawings.

[0021] According to the appendix Figures 1-6 As shown, the conveying fixture for cold-rolled steel sheet production of the present invention is implemented as follows: The conveying fixture for cold-rolled steel sheet production of the present invention includes a connecting frame structure 1. The connecting frame structure 1 has an installation groove 1.1 on one side for installing a track wheel structure. The track wheel structure includes an upper arc-shaped clamping plate 2 and a lower arc-shaped clamping plate 3, which can restrict the position of the rolling shaft 4. The rolling shaft 4 is clamped between the upper arc-shaped clamping plate 2 and the lower arc-shaped clamping plate 3. A cylindrical roller bearing 5 is sleeved on the outer side of one end of the rolling shaft 4 to facilitate the rotation of the track wheel 6. The track wheel 6 is sleeved on the outer side of the cylindrical roller bearing 5. A slotted roller 7 is fixed on the outer side of the track wheel 6. A bearing sealing cover 8 is provided on one side of the track wheel 6 to prevent the bearing from detaching from the shaft. The bearing sealing cover 8 is fixed to one side of the track wheel 6 by several fastening bolts 9 to fix the position of the bearing sealing cover 8.

[0022] The mounting groove 1.1 has a groove 1.2 on its upper side, and a limiting ring groove 1.3 is formed outside the groove 1.2. Deep grooves 1.4 are formed on both sides of the limiting ring groove 1.3 on the upper side of the mounting groove 1.1. A damping rod 10 is fixed on the upper side of the deep groove 1.4 to absorb impact. A limiting post 2.1 is fixed on the upper side of the upper arc-shaped clamping plate 2 at the groove 1.2, and a limiting cylinder 2.2 is fixed on the upper side of the upper arc-shaped clamping plate 2 at the limiting ring groove 1.3. The bottom end of the damping rod 10 is fixed on the upper side of the upper arc-shaped clamping plate 2. The limiting post 2.1 and the limiting cylinder 2.2 are respectively inserted into the groove 1.2 and the limiting ring groove 1.3. A rigid spring 11 is fixed between the upper side and the upper side of the groove 1.2; the upper arc-shaped clamping plate 2 and the lower arc-shaped clamping plate 3 are fixedly connected by bolts to facilitate limiting the position of the rolling shaft 4; a steel cable traction frame 12 is fixed at the bottom of the connecting frame structure 1 for hanging steel plates, and a drive motor 13 is fixed on one side of the steel cable traction frame 12; there are eight fastening bolts 9 in total, which can make the bearing sealing cover 8 more stable and prevent it from falling off; a limit plate 1.5 is fixed on both sides of the upper arc-shaped clamping plate 2 and the lower arc-shaped clamping plate 3 inside the mounting groove 1.1; the drive motor 13 is electrically connected to an external power source.

[0023] When transporting cold-rolled steel plates, the steel cable traction frame 12 is first controlled by the drive motor 13 to lift the steel plates. The connecting frame structure 1 is fixedly connected to the external prime mover to facilitate its movement on the crossbeam. After the steel plates are lifted, the rigid spring 11 and the damping rod 10 can play a certain buffering role to reduce the instantaneous pressure on the slotted roller 7. Then, during the transport of the steel plates, the cylindrical roller bearing 5 can better maintain the stable operation of the device.
