Description

Technical Field

[0001] This utility model relates to the technical field of water-cooling equipment for steel rolling mills, and in particular to a guide trough and a quick-change device for water cooling. Background Technology

[0002] Water cooling is a technique for post-rolling cooling of hot-rolled ribbed steel bars. By using water cooling, the temperature of the steel on the cooling bed can be lowered, improving the mechanical properties of the steel, increasing product quality and yield, and solving the problem of insufficient cooling bed capacity. However, in actual production, the specifications of the rolled steel often change, and the water cooling system and guide troughs sometimes need to be switched. Since the water cooling rollers are independent of each other, each requires separate replacement operations; this process often consumes a lot of manpower, resources, and time, seriously affecting production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-change device for the guide trough and the water cooling device. It is based on the original base and has been widened and modified to realize the horizontal parallel installation of the guide trough roller and the water cooling device. Both are deployed on the widened base, and a pulley system and slide rail facilities are added below the base. Its movement and positioning are completed by a drive device installed on the side of the base, which can facilitate the switching of the water cooling system and the guide trough, reduce labor intensity, and improve production efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A quick-change device for guide channels and water-passing devices includes a pit and an extended base frame. The pit is located on the ground in a steel rolling production line. Several parallel crossbeams perpendicular to the production line direction are provided in the pit. Moving slide rails are provided on the crossbeams. The bottom of the extended base frame is provided with matching rollers that slide along the moving slide rails. Parallel guide channel devices and water-passing devices are provided on the top of the extended base frame. A drive device is connected to one side of the pit. The output end of the drive device is connected to the extended base frame, driving it to move until the guide channel device or water-passing device is aligned with the production line.

[0006] Furthermore, a water injection device is provided on one side of the pit. The water injection device is connected to several water injection hoses, and the other end of the water injection hoses is connected to a water-passing device. The middle part of the water injection hose hangs down into the pit under its own weight.

[0007] Furthermore, the drive device includes a hydraulic cylinder.

[0008] Furthermore, one end of the hydraulic cylinder is hinged to the fixed base, and the other end is connected to the widened base frame.

[0009] Furthermore, the guide groove device is detachably connected to the widened base frame.

[0010] Furthermore, the widened base frame is connected to several base frame columns, and a base frame horizontal plate is connected above the base frame columns. The guide groove device is detachably connected to the base frame horizontal plate. Several fixed columns are connected to one or both ends of the pit. A fixed horizontal plate is connected above the fixed columns. The fixed horizontal plate is at the same height as the base frame horizontal plate. A fixed guide groove is detachably connected to the fixed horizontal plate.

[0011] Furthermore, the movable slide rail is connected to a fixed limiting block at one end away from and / or near the drive device, and the widened base frame is moved to a position abutting against the fixed limiting block, so that the corresponding guide groove device and / or water-passing device are aligned with the production line position.

[0012] Furthermore, the movable slide rail is also connected to several movable limiting blocks. The movable limiting blocks are detachably connected to the movable slide rail. The fixed limiting blocks and the movable limiting blocks respectively abut against the two sides of the widened base frame to restrict its movement.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The modified structure integrates the roller conveyor and the water cooling device, allowing them to be moved and adjusted as a unified module. This improvement simplifies the originally cumbersome maintenance and replacement process. Compared with the original separate replacement, this application greatly shortens the replacement cycle and significantly improves the efficiency of maintenance operations.

[0015] The base structure is fitted with pulleys and the ground is laid with rails. This combination ensures that the entire device can move and position smoothly and accurately. It not only shows great flexibility in daily operation, but also responds quickly when the production line layout needs to be adjusted, and easily adapts to diverse production needs.

[0016] A hydraulic cylinder drive system is used to drive the movement and positioning of the device. The equipment is installed in the pit, which facilitates the distribution and installation of main water pipelines and other lines, improves cleanliness, and facilitates maintenance. The application of the above technology not only realizes automated operation and significantly improves production efficiency, but also greatly reduces the complexity of manual operation and effectively reduces the risk of errors caused by human factors.

[0017] The above structure significantly improves the replacement efficiency between the roller conveyor and the water cooling device, thereby further enhancing the overall efficiency of the production line. At the same time, due to the significant reduction in maintenance and replacement time, the downtime of the production line is also shortened accordingly, thus improving the overall production capacity and efficiency.
