As shown in fig. 1-3, a rotary guardrail for a side plate of a hot-rolled layer cold region rolling line operation comprises a roll-over stand 1, wherein the roll-over stand 1 is connected with a cross beam 2, a rotating mechanism is arranged on the cross beam 2, and the rotating mechanism is connected with a guardrail.
The rotating mechanism comprises a fixing ring 3 horizontally arranged on the cross beam 2, and the fixing ring 3 is hinged with the guardrail; the guardrail comprises a guardrail body 4, a connecting rod 5 is connected above the guardrail body 4, and the connecting rod 5 is hinged with the fixing ring 3; the connecting rod 5 is provided with a small cross rod 6, and the small cross rod 6 is hinged with the fixing ring 3; the end of the small cross rod 6 passes through the fixing ring 3 and can rotate in the fixing ring 3; the end of the small cross rod 6 penetrates through the fixing ring 3 to be connected with a nut.
At present, no protective measures are taken on the side plate of the hot-rolled steel rolling line operation in the hot-rolled layer cold region, and the following problems exist:
1. when the personnel check the running state of the equipment, the personnel can only stand above the sideboard to check (because the inner side of the sideboard is a high-speed rotating roller way, potential safety hazard is brought to point inspection);
2. during production, the phenomenon that the strip steel flies out of the cold rolling channel sometimes occurs, and the high-temperature strip steel flies to the safety channel, so that great potential safety hazards exist;
3. the daily change of roll table or motor is more frequent, if install traditional guardrail, can only fix the guardrail on operation side board, and change the roll table and just need relapse dismouting guardrail, increase extra work load.
Therefore, the design concept of the scheme is that the rotatable guardrail is installed, so that the guardrail can play a role in protection in daily work, and the fault maintenance of equipment is not influenced.
The working principle of the application is as follows:
the guardrail is hinged with a cross beam fixed on the roll-over stand; when the roller is changed in normal production or process (as shown in figures 1 and 2), the rotary guardrail is positioned above the laminar cooling edge plate to play a daily safety protection role; when production faults occur or the roller way and the motor need to be replaced (as shown in figure 3), the overturning oil cylinder supplies oil through the rod cavity, the piston rod is retracted, the overturning frame is lifted, and the guardrail slowly rotates downwards along with the lifting due to self gravity, so that a process channel is avoided, and workers can conveniently handle the production faults or the equipment faults to replace the roller way, the motor and the like.
Benefit after this application installation: layer cold current situation does not have safety barrier device, installs this rotatory guardrail additional and has ensured safety on the one hand, and on the other hand has reduced the repeatability problems such as dismantling repeatedly after traditional guardrail installation.
Although the present invention has been described in detail with reference to the preferred embodiments, the present invention is not limited thereto, and those skilled in the art can make various equivalent modifications or substitutions on the embodiments of the present invention without departing from the spirit and essence of the present invention, and those modifications or substitutions should be considered as being within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present disclosure, and therefore, the scope of the present invention should be determined by the scope of the claims.
