Description

Technical Field

[0001] The utility model relates to the technical field of hot straightening machines, and specifically relates to a protection device for the equipment behind a new type of hot straightening machine. Background Technique

[0002] The hot straightening machine is one of the main equipment commonly configured in the heavy plate production line of the steel industry and is used for leveling rolled steel plates. The hot straightening machine is usually arranged after the steel plate accelerated cooling equipment behind the finishing mill. An automatic hot stamping machine or an automatic steel plate surface defect inspection equipment is usually arranged behind the hot straightening machine to realize the automatic identification and alarm of the surface defects such as the plate number automatic identification stamping on the surface of the hot steel plate after straightening and the surface indentation, roll marks, and pitting of the steel plate surface.

[0003] In the industry, there are often situations where the steel plate surface hot stamping machine or the steel plate surface defect inspection equipment behind the hot straightening machine is damaged by the impact of the warped and bent steel plate after straightening. The steel plate surface hot stamping machine or the steel plate surface defect inspection equipment is often severely damaged after being hit, and the repair time is usually more than several weeks, and the repair cost is high, which brings great inconvenience and losses to the normal production of the production line.

[0004] At present, there are mainly two types of protection devices for the equipment behind the hot straightening machine in the industry, and both have limitations. One type is the protection device such as "an anti-collision device (201720633205.2) for a steel plate online stamping machine", which is only applicable to the protection of the equipment behind the hot straightening machine with a small warping degree of the steel plate after straightening within a certain limit, and can only protect some equipment components below a certain elevation behind the hot straightening machine, such as the stamping machine nozzle, and cannot realize the protection of all equipment components behind the hot straightening machine, such as the frame, cross beam, guide rail and other components of the stamping machine or the surface inspection equipment; the other type is the protection device such as "an anti-collision device for a stamping machine (201720762975.7)", and this type of protection device uses the principle of photoelectric induction and uses a photoelectric limit device to sense the warping degree of the warped steel plate after straightening. Its limitation is that due to the different warping and bending degrees of the warped steel plate after straightening, the positions where it can be sensed by the photoelectric induction device are also different. At the position where the photoelectric induction device is located, only some warped steel plates with a certain warping and bending degree can be sensed, and all warped steel plates with different warping and bending degrees cannot be covered. Moreover, the photoelectric induction device is easily affected by dust, water vapor, etc. in the environment and may cause induction failure, false induction and other situations, affecting the normal operation of the induction device. Therefore, the present utility model provides a protection device for the equipment behind a new type of hot straightening machine to solve the above problems. Content of the Utility Model

[0025] Embodiment: As Figures 1-3 , the present utility model provides a technical solution, including the equipment 1 behind the hot straightening machine, the protection device 2 for the equipment behind the hot straightening machine, the steel plate 3 with the head warping upwards after straightening by the straightening machine, and the hot straightening machine 4. The steel plate 3 with the head warping upwards after straightening by the straightening machine is arranged at the left end of the hot straightening machine 4. The protection device 2 for the equipment behind the hot straightening machine is arranged at the upper left side of the steel plate 3 with the head warping upwards after straightening by the straightening machine, and the equipment 1 behind the hot straightening machine is installed at the left side of the protection device 2 for the equipment behind the hot straightening machine;

[0026] The protection device 2 for the equipment behind the hot straightening machine includes a protection device fixing plate 201, a protection device bottom plate 202, a connecting member 203 between the protection device bottom plate and the proximity switch fixing plate, a proximity switch fixing plate 204, a proximity switch stop iron 205, a spring 206, a spring fixing hook 207, a horizontal rotating shaft 208 of the cantilever rod, a rotary support seat 209 of the cantilever rod, a proximity switch 210, a proximity switch adjusting nut 211, a vertical rod 212 of the cantilever rod, and a horizontal rod 213 of the cantilever rod;

[0027] The device fixing plate 201 is welded and fixed to the bottom of the steel section at its top. The protection device bottom plate 202 is connected to the protection device fixing plate 201 above it by bolts. The connecting member 203 between the protection device bottom plate and the proximity switch fixing plate is made of angle steel and is fixed to the protection device fixing plate and the protection device bottom plate by bolts. The proximity switch fixing plate 204 is fixed to the connecting member 203 between the protection device bottom plate and the proximity switch fixing plate by bolts. The bolt holes on the connecting member 203 are all designed as slots, so that the position of the proximity switch fixing plate 204 can be adjusted in the horizontal and vertical directions. The proximity switch 210 is fixed on the proximity switch fixing plate. The proximity switch 210 realizes the position adjustment and fixation in the horizontal direction through two proximity switch adjustment nuts 211;

[0028] A rotatable suspension rod device is arranged below the protection device bottom plate 202. The horizontal rotating shaft 208 of the suspension rod device is arranged in the rotary support seat 209 of the suspension rod. The rotary support seat 209 of the suspension rod is welded and fixed below the protection device bottom plate 202. The vertical rod 212 of the suspension rod is welded and fixed to the middle of the horizontal rotating shaft 208.

The horizontal rod 213 of the suspension rod is designed in a T shape, with an extending part in the direction of steel plate conveying at the front end. Both the vertical rod and the horizontal rod of the suspension rod are made of steel. A proximity switch stop iron 205 is welded and fixed to the upper half of the vertical rod 212 of the suspension rod. The end of the proximity switch stop iron 205 is suspended and fixed on the spring 206. The spring 206 is fixed to the protection device bottom plate 202 by a spring fixing hook 207. The function of the spring is that when the hot straightening machine operates normally, the steel plate has a normal shape after straightening and there is no warping, the proximity switch stop iron 205 is in the position where the proximity switch 210 is induced.

[0029] Working principle: When the steel plate after being straightened by the hot straightening machine shows the situation of warping head as shown in the figure, when the steel plate continues to be conveyed behind the hot straightening machine, without the protection device for the equipment behind the hot straightening machine, the warping head steel plate will damage the equipment behind the hot straightening machine, resulting in long-term production line shutdown and economic losses caused by equipment damage. When the protection device for the equipment behind the hot straightening machine proposed by the present utility model is set, the warping head steel plate will touch the protection device for the equipment behind the hot straightening machine proposed by the present utility model - when the warping degree of the warping head of the steel plate behind the hot straightening machine is relatively large, it will touch the vertical rod of the cantilever rod, and when the warping degree of the warping head of the steel plate is relatively small, it will touch the extended part at the front end of the horizontal rod of the cantilever rod. The touch of the warping head steel plate will cause the vertical rod of the cantilever rod, the horizontal rod of the cantilever rod, and the proximity switch stop iron fixed on the vertical rod of the cantilever rod of this protection device for the equipment behind the hot straightening machine to rotate a certain angle around the center of the horizontal rotating shaft, resulting in the proximity switch losing the induction signal. An automatic control program is compiled in the automatic control system. The loss of the induction signal of the proximity switch causes the straightening rolls of the straightening machine and the conveying roller table behind the straightening machine to stop rotating automatically, and at the same time gives an alarm. The warping head steel plate after straightening stops automatically on the roller table, avoiding its impact damage to the equipment behind the hot straightening machine, thereby realizing the automatic protection of the equipment behind the hot straightening machine.

[0030] Beneficial effects: Adopting the principle that "the warping head steel plate after straightening will touch the suspension rod of the protection device, causing the suspension rod assembly to rotate a certain angle, thereby changing the position of the proximity switch stop iron, making the proximity switch lose the induction signal, and the program interlock causes the straightening rolls of the straightening machine and the conveying roller table behind the straightening machine to stop rotating automatically, so that the warping head steel plate after straightening stops automatically on the roller table, avoiding its impact damage to the equipment behind the hot straightening machine.", it operates stably and reliably, and will not be affected by common dust, water vapor, etc. in the rolling mill workshop environment, resulting in induction failure, false induction, etc.

[0031] In the present utility model, the vertical rod of the cantilever of the protection device is welded and fixed in the middle of the horizontal rotating shaft, the horizontal rod of the cantilever is welded and fixed at the lower end of the vertical rod of the cantilever. The horizontal rod of the cantilever is designed in a T shape, with a certain length of extended part in the steel plate conveying direction at the front end. This design covers all warping degree ranges of warping head steel plates that may cause damage to the equipment behind the hot straightening machine. The protection of the equipment behind the hot straightening machine is perfect and reliable.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
