Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cooling bed equipment, in particular to an automatic resetting device for a steel rolling cooling bed sensor and a cooling bed. Background Art
[0002] The stepping motion of the cooling bed in the steel rolling mill and the signal handover of the upstream and downstream equipment are all realized by the travel limit switches at the input and output ends. The travel limit switch has a compact structure, with a cam connecting rod on the outside, and mainly springs, dynamic and static contact terminals, etc. on the inside. Personnel need to be arranged to inspect whether the electrical or mechanical parts at each connection point meet normal requirements, and the work is labor-intensive. The limit switch equipment is compact and can only be installed at a close distance. The high temperature of the steel billet seriously affects the service life. At the same time, the ambient temperature is high when personnel inspect or handle faults, and burns are prone to occur. Any failure in the mechanical structure of the limit switch will cause the cooling bed to fail to move, especially the electrical contacts are prone to poor contact, and at the same time cause accidents of upstream and downstream related equipment, resulting in accidents such as steel piling and other line shutdowns.

[0020] The utility model is further described below in conjunction with specific embodiments.
[0021] like Figure 1~2 The automatic reset device of the rolling mill cooling bed sensor shown in the figure comprises a lever 4, a rotating shaft 3 and a sensor 5. The lever 4 rotates around the rotating shaft 3. The rotating shaft 3 is arranged in the middle of the lever 4 and is connected to the cooling bed base 8 through a connecting piece 10, thereby fixing the lever 4. The upper end of the lever 4 touches the billet 1. In order to save the consumption of equipment parts and keep away from the high temperature of the billet 1, a sensor 5 is arranged at the bottom end of the lever 4.
[0022] In this embodiment, the material of the lever 4 is steel.
[0023] like Figure 3 The cooling bed shown comprises a sensor 5, a controller and a display. The sensor is connected to the controller to transmit the detected signal to the controller. The controller is connected to the display.
[0024] In this embodiment, the sensor 5 is a conventional pressure sensor available on the market.
[0025] In this embodiment, the controller is a 51 single chip microcomputer, model STC89C52.
[0026] In actual operation, the utility model is provided with a sensor 5 at each input and output end of the cooling bed 7, and a pressure range is preset in the controller. When the billet 1 steps on the steel teeth 2 of the cooling bed 7, it touches the upper end of the lever 4 of the utility model, causing the lever to rotate around the rotating shaft 3, and the lever 4 drives the sensor 5 to touch the obstacle 9 set under the crossbeam 6, and transmits the pressure signal to the controller. The controller receives and processes and analyzes the real-time pressure data measured by the sensor 5, and displays the pressure analysis results through the display, completing the stepping action of the cooling bed 7 and the signal handover of the upstream and downstream equipment, and more comprehensively monitoring the pressure information of the working environment of the cooling bed 7 equipment. The billet 1 leaves, and the lever 4 and the sensor 5 are reset.
[0027] If the cooling bed 7 equipment fails, the real-time pressure data measured by the sensor 5 is compared with the preset pressure range. If the real-time pressure data measured by the sensor 5 does not belong to the preset pressure range of the controller, the cooling bed 7 equipment is judged to have failed, and the position of the sensor 5 where the failure occurred is displayed on the display. At the same time, the controller transmits a shutdown signal to the upstream and downstream equipment. The time for manual inspection and troubleshooting is reduced, thereby reducing the non-operation of the cooling bed 7 due to any failure of the equipment, especially the failure of the upstream and downstream related equipment, resulting in the whole line stopping production accidents such as steel piling, and improving the utilization rate and safety of personnel and equipment.
