Description

Technical Field

[0001] The utility model relates to the field of casting blank transfer rollers, in particular to a disassembly and maintenance auxiliary device for the transfer rollers of the sector segments of a continuous casting machine. Background Art

[0002] At present, the weight of the steel billets conveyed by the transfer rollers of the sector segment casting blanks reaches dozens of tons. Due to the large pressure, the bearings inside the transfer rollers are often damaged and the shafts are worn. It is necessary to remove the transfer rollers offline for maintenance and then replace the damaged parts. However, due to the large volume and high weight of the transfer rollers, a large amount of manpower and material resources are required to remove the roller sleeves. It is necessary to use a hoist to lift the transfer roller and place it on the ground for fixation, and then the maintenance personnel use a sledgehammer to strike one end of the roller shaft at one end of the transfer roller until the roller shaft is separated from the roller sleeve. This step consumes a lot of physical strength of the maintenance personnel, is slow, and has low efficiency; moreover, the impact force of striking one end of the roller shaft with a sledgehammer will cause damage to the internal components of the transmission shaft, increasing unnecessary maintenance work; for various reasons, the maintenance of the transfer rollers is slow and cannot keep up with the production demand, severely restricting the production work. Summary of the Invention

[0003] In view of the above problems, the utility model provides an auxiliary device for quickly disassembling large transfer rollers without manual labor. The specific scheme is as follows:

[0004] A disassembly and maintenance auxiliary device for the transfer rollers of the sector segments of a continuous casting machine, comprising:

[0005] A guide rail;

[0006] A roller path placement rack slidably connected to the guide rail, which is used for placing the transfer roller, and an arc-shaped groove that fits the outer wall of the roller sleeve of the transfer roller is provided on the roller path placement rack;

[0007] A jacking mechanism, which is located at one end of the guide rail, and its output end abuts against the roller shaft of the transfer roller;

[0008] An auxiliary device frame, which is arranged on the side of the guide rail and is parallel to the guide rail;

[0009] A limiting mechanism, which is used to block the axial displacement of the transfer roller on the guide rail to cooperate with the jacking mechanism to push out the roller shaft.

[0010] Further, the limiting mechanism includes:

[0011] A guide rail positioning frame, which is detachably connected to the auxiliary device frame and is located above the transfer roller;

[0012] A baffle plate, the top of which is fixedly connected to the guide rail positioning frame and extends to the roller shaft of the transfer roller, and the baffle plate is located at the front end in the moving direction of the roller sleeve.

[0013] Further, a plurality of positioning holes are arranged on the auxiliary device rack in sequence along its length direction.

[0014] Further, one auxiliary device rack is respectively arranged on both sides of the guide rail. Both of the two auxiliary device racks are higher than the height of the transmission roller. The guide rail positioning rack spans between the tops of the two auxiliary device racks. Positioning pins respectively corresponding to the positioning holes on the two auxiliary device racks are arranged at both ends of the guide rail positioning rack.

[0015] Further, a plurality of roller sleeves are coaxially sleeved on the roller shaft, and a plurality of roller track placement racks corresponding to the plurality of roller sleeves are also provided.

[0016] Further, a bearing seat is installed on the roller shaft between the plurality of roller sleeves, and the baffle is clamped into the gap between the roller sleeve and the bearing seat.

[0017] Further, a U-shaped card slot clamped with the roller shaft is formed at the bottom of the baffle.

[0018] Further, a hydraulic station is arranged at the rear of the hydraulic cylinder. A hydraulic pipe is connected between the hydraulic cylinder and the hydraulic station. An electromagnetic valve is installed on the hydraulic pipe. A control switch electrically connected to the electromagnetic valve is arranged on the side of the hydraulic cylinder.

[0019] Compared with the prior art, the advantages of the present utility model are as follows:

[0020] 1. The present utility model blocks the movement of the roller sleeve through the baffle, and cooperates with the pushing mechanism to push the roller shaft out of the roller sleeve, without manual disassembly, improving the work efficiency.

[0021] 2. The pushing mechanism of the present utility model is a hydraulic cylinder, which outputs a continuous pushing force to the end of the roller shaft and will not generate an impact on the transmission roller, avoiding damage to the components in the transmission roller.

[0022] 3. The baffle of the present utility model is in contact with the end face of the roller sleeve. Because the end area of the roller sleeve is large, the thrust applied to the baffle by it is relatively dispersed and will not cause the baffle to be damaged by extrusion.

[0023] 4. The present utility model can fix the transmission roller by arranging the baffle in the gap between the bearing seat and the roller sleeve, facilitating the pushing mechanism to push the roller shaft.

[0024] 5. The present utility model arranges a U-shaped card slot clamped with the roller shaft at the bottom of the baffle, enabling the U-shaped card slot to penetrate into the gap, increasing the contact area between the baffle and the end face of the roller sleeve as much as possible, further dispersing the thrust, and further avoiding the baffle from being damaged by the pushing force.
