Description

Technical Field

[0001] This invention relates to the field of replacing rollers, bearing housings, or frames in equipment for processing silicon steel or cold-rolled strip steel, specifically to a manual roller changing trolley and its usage method. Background Technology

[0002] Rolls are commonly used components in the rolling process of the metallurgical industry. There are various types, such as conveyor rolls, guide rolls, and pressure rolls. Rolls need to be replaced after they wear out. Currently, there are two ways to change rolls. One is to use a maintenance beam and hoist or a combination of hoisting and lifting points to lift and change the roll. This method requires unobstructed space above the roll. The other method is to use a roll changing trolley to hold the shaft head and pull it out. This method requires sufficient unobstructed space on the side. Both methods require a large working space, which limits the flexibility of roll changing. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology and provide a rolling auxiliary equipment with simple structure, convenient operation, low working space requirements and strong adaptability, this invention discloses a manual roll changing trolley and its usage method.

[0004] The present invention achieves its objective through the following technical solution: A manual roller changing trolley includes tracks and a trolley body. Two tracks are laid parallel to each other on one side of the roller changing equipment on the ground. Two wheels are respectively provided on both sides of the bottom surface of the trolley body. The trolley body is movably mounted on the two tracks by means of the wheels on both sides. The trolley body is characterized by further including a lifting device and a lifting seat. The lifting device is mounted on the trolley body. The moving end of the lifting rod of the lifting device is connected to the bottom surface of the lifting seat. The top surface of the lifting seat is a concave arc surface.

[0005] The manual roller changing trolley is characterized in that it further includes a stop block and a guide rod. Stop blocks are provided at both ends of the track; The vehicle body has guide holes on both sides of the lifting device. A guide rod is inserted into each guide hole. The outer diameter of the guide rod and the diameter of the guide hole form a clearance fit. The top of the guide rod is fixed to the bottom surface of the lifting seat and the two sides of the connection between the lifting rod and the lifting device.

[0006] The manual roller changing trolley is characterized in that: the lifting device is a manual jack.

[0007] The method of using the manual roller changing trolley is characterized by the following steps being performed sequentially: S1. Fitting: Drive the vehicle body along the track to the area below the roller to be replaced on the roller replacement equipment, raise the lifting seat through the lifting device, and stop the lifting device when the concave arc-shaped top surface of the lifting seat fits the roller to be replaced. S2. Support: Disconnect the roller to be replaced from other components of the equipment, so that the roller to be replaced is fully supported by the lifting seat; S3. Replacement: Drive the vehicle body along the track by the wheels to leave the equipment that needs to replace the roller, and replace the roller to be replaced.

[0008] This invention has a simple structure, requires no power equipment such as motors and cylinders, and does not require sliding contact cables and drag chains. It is easy to operate, has low requirements for working space, and is convenient for roller changing operations in situations where the upper and side spaces are limited. It can also achieve long-distance lateral movement. Attached Figure Description

[0009] Figure 1 This is the front view of the present invention. Figure 2 This is the right view of the present invention. Detailed Implementation

[0010] The present invention will be further illustrated below through specific embodiments. Example

[0011] A manual roller changing trolley includes a track 1 and a trolley body 2, such as Figure 1 and Figure 2 As shown, the specific structure is: Two parallel tracks 1 are laid on the ground on one side of the roller changing equipment. Two wheels 21 are provided on both sides of the bottom surface of the car body 2. The car body 2 is movably mounted on the two tracks 1 by means of the wheels 21 on both sides. The feature is that it also includes a lifting device 22 and a lifting seat 23. The lifting device 22 is mounted on the car body 2. The moving end of the lifting rod of the lifting device 22 is connected to the bottom surface of the lifting seat 23. The top surface of the lifting seat 23 is a concave arc surface.

[0012] This embodiment also includes a stop block 11 and a guide rod 24. Stop blocks 11 are provided at both ends of track 1; The vehicle body 2 has guide holes 25 on both sides of the lifting device 22. A guide rod 24 is inserted into each guide hole 25. The outer diameter of the guide rod 24 and the diameter of the guide hole 25 form a clearance fit. The top of the guide rod 24 is fixed on both sides of the bottom surface of the lifting seat 23 and the connection of the lifting rod of the lifting device 22.

[0013] In this embodiment, the lifting device 22 is a manual jack.

[0014] When using this embodiment, follow these steps in sequence: S1. Adhesion: The drive vehicle 2 travels along the track 1 via the wheels 21 to the area below the roller 3 to be replaced in the roller replacement equipment. The lifting seat 23 is raised by the lifting device 22. The lifting device 22 is stopped when the concave arc-shaped top surface of the lifting seat 23 is in contact with the roller 3 to be replaced. S2. Support: Disconnect the roller to be replaced 3 from other components of the roller replacement equipment so that the roller to be replaced 3 is fully supported by the lifting seat 23; S3. Replacement: Drive the vehicle body 2 away from the roller replacement equipment via the wheels 21 along the track 1 and replace the roller to be replaced 3.

[0015] When using this embodiment: Stop block 11 prevents wheel 21 from slipping off track 1; Different concave arc surfaces can be selected for the lifting seat 23 of the different replacement rollers 3 to adapt to rollers 3 with different outer diameters; The guide rod 24 is used to ensure the stability of the lifting seat 23 during lifting.
