Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment in the metallurgical industry, and more specifically, to a position detection device for a turning cooling bed of a continuous casting machine. Background Art

[0002] In the steel production process, continuous casting of steel billets is one of the important processes in the production system. The bending degree of steel billets directly affects the heating furnace input rate of the steel rolling process. Therefore, it is necessary to minimize the bending of steel billets and increase the heating furnace input rate of the steel rolling process. In the continuous casting production process, Figure 1 As shown, the heat dissipation of the billet 13 is uniform mainly by turning over the cooling bed, thereby reducing the bending of the billet 13. The principle is that the billet 13 is separated by a standard gap between the movable tooth plate 14 and the fixed tooth plate 15 of the turning cooling bed, and the bent and deformed billet 13 is straightened by continuous turning. The turning cooling bed adopts a hydraulic drive mode, and the lifting cylinder and the transverse cylinder drive the lifting synchronous shaft and the transverse synchronous shaft to rotate respectively. The wheels of the lifting frame 17 and the transverse frame 16 are connected by a pull rod and move with the track, thereby realizing a four-step action cycle of movable tooth plate rising-movable tooth plate moving forward-movable tooth plate falling-movable tooth plate retreating-movable tooth plate rising.

[0003] The position of the turning cooling bed during operation is determined by the proximity switch, and the proximity switch is generally installed on the track position of the turning cooling bed lifting frame 17 and the lateral frame 16, but its design has the following disadvantages: 1. The temperature of the billet on the turning cooling bed is 800-900℃, and the proximity switch is installed about 1.5m directly below the billet. In a high temperature environment, the proximity switch and the signal cable are prone to failure; 2. The protective slag skin of the billet falls to the proximity switch with the movement of the turning cooling bed, making the proximity switch inaccurate; 3. During the rotation process, the turning cooling bed shakes greatly as a whole, causing the proximity switch to shake as well, which is easy to cause the proximity switch to loosen and affect the positioning accuracy of the proximity switch. The above disadvantages all affect the quality of the billet, and when the proximity switch device is abnormal and needs maintenance, the operator needs to manually operate the turning cooling bed to turn all the billets to the back of the collection stand for maintenance, which increases the labor intensity of the workers and affects the continuous casting production efficiency. Therefore, it is urgent to develop and design a new type of continuous casting machine turning cooling bed position detection device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a continuous casting machine turning cooling bed position detection device in view of the above-mentioned deficiencies in the prior art, so as to reduce the equipment failure rate, ensure the smooth continuous casting production, and improve the continuous casting production efficiency and the billet heating furnace entry rate.

[0005] The technical solution of the utility model is as follows: a continuous casting machine turning cooling bed position detection device, including a lifting synchronous shaft, a transverse synchronous shaft, and a proximity switch, one end of the lifting synchronous shaft is sleeved with a lifting synchronous shaft support, one end of the transverse synchronous shaft is sleeved with a transverse synchronous shaft support, the end surfaces of one end of the lifting synchronous shaft and the transverse synchronous shaft are provided with a swing rod matching the proximity switch, the end surfaces of the lifting synchronous shaft support and the transverse synchronous shaft support are provided with a mounting base, the mounting base is provided with a mounting panel, and the proximity switch is mounted on the mounting panel.

[0006] As a further improvement, there are two proximity switches on each of the mounting panels.

[0007] Furthermore, the two proximity switches are distributed on an arc with the lifting synchronization shaft or the transverse movement synchronization shaft as the center, and the two swing rods are respectively installed on the central axes of the lifting synchronization shaft and the transverse movement synchronization shaft.

[0008] Furthermore, the proximity switch is a photoelectric proximity switch.

[0009] Furthermore, the mounting base is connected to the mounting panel by welding.

[0010] Furthermore, the swing rod includes a telescopic rod and a sensor plate, wherein the sensor plate is installed at one end of the telescopic rod, and the other end of the telescopic rod is connected to the corresponding end face of the synchronous shaft.

[0011] Furthermore, a connecting plate perpendicular to the mounting base is provided on one side of the mounting base, and one end of the connecting plate is connected to the corresponding synchronous shaft support.

[0012] Furthermore, there are two connecting plates on each of the mounting bases.

[0013] Beneficial Effects

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The utility model discloses a position detection device for a continuous casting machine turning cooling bed. The position detection device is installed on the end faces of a lifting synchronous shaft, a transverse synchronous shaft and a support, and is far away from the steel billet on the turning cooling bed. This can avoid the influence of the high temperature of the steel billet and the falling of the protective slag skin on the proximity switch. The device has a simple structure and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS
