Description

Technical Field

[0001] The utility model relates to a quick disassembly device for a pickling rolling loop isolation arm roller, and belongs to the technical field of cold rolling processing equipment in the metallurgical industry. Background Art

[0002] The pickling process section of the high-strength automobile plate pickling rolling line has three horizontal loopers at the entrance, middle and exit. The entrance, middle and exit loopers are used to store strip steel of sufficient length to ensure continuous production of the pickling section, process section section and mill exit section when the entrance section, process section and mill section are stopped. Fixedly installed strip support rollers support the lower strip steel. When filling the looper, the isolation arm rollers support the upper strip steel of the looper to prevent the strip steels between layers from contacting each other. The looper winch drive system is used to maintain the necessary strip tension. The diverting pulley is used to transfer the wire rope back to the looper car. A hydraulic cylinder is used to maintain the wire rope tension, prevent the wire rope from slipping and compensate for the elongation. The looper system includes a looper car running on a track and supporting the diverting rollers, the rolling line rollers and roller supports, isolation arms, winch drive systems and auxiliary equipment, such as Figure 1 shown.

[0003] The loop isolation arm device is installed along both sides of the looper track, including a vertical shaft with a transverse isolation arm. Each isolation arm of the isolation device is equipped with an isolation arm roller. The roller is a free roller and is installed in an adjustable position associated with the vertical shaft. The isolation arm relies on the cam mechanism installed on both sides of the looper to swing synchronously during the operation of the looper. When the isolation arm is closed, it supports the strip steel and opens to provide a channel for the operation of the looper. The isolation arm device is as follows Figure 2 shown.

[0004] The isolation arm roller is a free roller, and the roller surface is made of polyurethane. It wears quickly during contact with the strip. On the one hand, the roller body wears inconsistently, causing the strip to deviate during the loop operation, affecting the rolling rhythm. On the other hand, if the roller body is severely worn, the steel part of the roller body will be exposed, scratching the strip and causing quality accidents. Therefore, the roller needs to be replaced regularly. Figure 3 This is a schematic diagram of roller installation. The isolation arm roller is installed in the isolation arm main frame. The distance between the roller and the vertical shaft base is close, only 19.5mm. In the past, when replacing the roller, a sledgehammer and a crowbar were used to remove the isolation arm roller from the isolation arm frame, which was time-consuming and laborious, and also caused certain damage to the roller itself. Utility Model Content

[0005] The utility model aims to provide a quick disassembly device for rollers of acid rolling live sleeve isolation arms, which can conveniently and quickly disassemble the rollers without damaging the rollers, thereby solving the problems existing in the background technology.

[0006] The technical solution of the utility model is:

[0007] A quick disassembly device for a pickling rolling live-loop isolation arm roller comprises an isolation arm roller, an isolation arm frame, a C-shaped block, a clamping plate and a top screw. The isolation arm roller is installed in the isolation arm main frame, the clamping plate is arranged between the isolation arm roller and the isolation arm frame, the C-shaped block is buckled on the isolation arm frame, and top screws matching the clamping plate are respectively arranged on both sides of the C-shaped block.

[0008] The top screw is threadedly connected to a top screw seat, and the top screw seat is fixed on both sides of the C-shaped block.

[0009] The top screw is pressed against the clamping plate.

[0010] The clamping plate is a U-shaped structure matched with the roller neck of the isolation arm support roller.

[0011] The clamping plate is clamped in the gap between the isolation arm supporting roller and the isolation arm frame.

[0012] The utility model has the beneficial effects of simple structure, convenient operation, being able to remove the pickling rolling loop isolation arm roller intact, saving time and labor, reducing labor intensity and eliminating safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0022] See attached Figure 4-7A quick disassembly device for a pickling rolling live-loop isolation arm roller comprises an isolation arm roller 1, an isolation arm main frame 2, a C-shaped block 3, a clamping plate 4 and a top screw 5. The isolation arm roller 1 is installed in the isolation arm main frame 2, the clamping plate 4 is arranged between the isolation arm roller 1 and the isolation arm main frame 2, the C-shaped block 3 is buckled on the isolation arm main frame 2, and top screws 5 matching with the clamping plate 4 are respectively arranged on both sides of the C-shaped block 3.

[0023] In this embodiment, first, refer to the attached Figure 3 , make C-shaped block 3 and clamping plate 4 according to the installation dimensions of isolation arm roller 1 and isolation arm main frame 2.

[0024] See attached Figure 6 The clamping plate 4 is made of 18mm thick steel plate into 200×322mm, with a 102mm "U"-shaped groove in the middle to clamp the journal of the isolation arm roller 1.

[0025] See attached Figure 7 The C-type block 3 is made of 20mm thick steel plate to form a C-type structure. The size of the middle inner cavity of the C-type block 3 is determined according to the isolation arm frame 2. M20 top screw seats 6 are welded on both sides for screwing in the top screws 5.
