Description

Technical Field

[0001] The utility model relates to the technical field of intelligent (unmanned) cranes in the steel industry, and particularly relates to a horizontal coil gripper for preventing steel coils from tipping over. Background Technique

[0002] There are 45 intelligent (unmanned) cranes in the lifting department of the rare earth steel cold rolling sheet plant of Baotou Steel Co., Ltd., which are mainly distributed in the raw material warehouse, the post-rolling warehouse and the finished product warehouse. Their main functions are to load coils for pickling cold rolling, pickling, continuous annealing and galvanizing, and to be responsible for the packaging and shipping work in the finished product warehouse. Since the cranes of the affiliated production lines are all intelligent cranes, the coil loading and lifting are realized through the control of the system program. If there is interference in this program, slight tremors or transient program amnesia may occur, which is not a big problem during operation. Only when the steel coil falls onto the saddle, the slight vibration will cause the coil on the saddle to deviate from the center position, resulting in one side of the gripper still being at the coil core when the gripper is in the open state, while the feedback signal of the intelligent crane is that all are open and the lifting instruction can be given. At this time, the steel coil will tip over due to one side not detaching from the coil core, or the steel coil will slip when lifted on one side, and the steel coil will tip over when the coil transport trolley moves and lifts but is not in the center position. Once the steel coil tips over (the weight of the steel coil is about 23 tons), it will cause damage to the surrounding steel floor plates at least, and at worst, it will damage the coil transport trolley and the pipelines and electrical facilities of the auxiliary equipment, and it will be extremely difficult to handle, directly resulting in production stoppage.

[0003] In order to improve the smooth operation of the production line and avoid accidents, the transformation of a horizontal coil gripper for preventing steel coils from tipping over is particularly important, which can not only improve the smooth operation of the crane but also ensure the continuous production of the production line.

[0029] Embodiment 2

[0030] This embodiment also provides a horizontal coil gripper for preventing the steel coil from tipping over in Embodiment 1, including the following steps:

[0031] The first detection device and the second detection device are signal-connected to the control system of the crane. When the first detection device detects that the first gripper 3 has not detached from the steel coil, the first detection device transmits a signal to the control system of the crane, and the control system of the crane stops the lifting of the gripper body.

[0032] The horizontal coil gripper provided by the present utility model avoids the steel coil from tipping over and falling, reducing the probability of quality and production accidents. According to the analysis of the most minor accidents in the tipping-over and falling accidents in 2022, it is necessary to stop the machine for 30 minutes, and the number of coil falling times throughout the year is 8 times. The total accident time (240 minutes) is 4 hours. In 2023, a total of 4 hours of downtime has been avoided. Calculated according to the annual output of 1.28 million tons in the previous year:

[0033] The daily output in terms of conversion is: 1,280,000 tons ÷ 365 days ≈ 3506 tons;

[0034] The output per hour is: 3506 tons ÷ 24 hours ≈ 146 tons;

[0035] By comparison, the increased output is: 4 hours × 146 tons = 584 tons. Combining with the current average profit per ton of about 600 yuan, the profit that can be created is 584 tons × 600 yuan = 350,400 yuan.

[0036] The replacement cost of spare parts and labor costs for damaged surrounding equipment and facilities in case of serious accidents are not counted temporarily.
