Description

Technical Field

[0001] The utility model belongs to the technical field of cold continuous rolling strip steel and relates to a detection device for preventing the rollover of a walking beam steel coil. Background Art

[0002] Walking beam is one of the most commonly used steel coil transportation equipment in steel rolling mills. The steel coil coming out of the hot rolling coiler is generally transported by walking beam, and then transported to the finished product warehouse by fast chain and slow chain. The entrances and exits of cold rolling, galvanizing and continuous annealing lines also use walking beams to transport steel coils. Walking beams are divided into entrance walking beams and exit walking beams according to their layout positions. Walking beams are generally underground, and fixed saddles of saddle-shaped welded structures are arranged on the walking beams. Each fixed saddle is arranged at a certain distance. The moving beam moves the steel coil from one fixed saddle to the next fixed saddle every time it runs for a cycle.

[0003] In the production of cold-rolled strip steel, the stability of rolling production is a problem of great concern. Due to unavoidable equipment wear, operational errors and other abnormal situations in the production process, when the unloading trolley transports the steel coil from the coil receiving position of the coiler or the inspection table back to the zero saddle position of the exit walking beam, the steel coil is not placed on the center line. When the exit walking beam rises, the steel coil overturns due to the different weights on both sides, causing the static beams on both sides to be smashed and deformed, affecting the production rhythm, damaging equipment and causing serious losses. Utility Model Content

[0004] The utility model provides a walking beam steel coil detection device to solve the problem that when the existing walking beam transports the steel coil, the steel coil overturns due to the different weights on both sides.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: it includes a walking beam and a controller, a detector, a first rangefinder and a second rangefinder are provided at the No. 0 saddle of the walking beam, the steel coil is transported to the No. 0 saddle, the detector is used to monitor whether there is a steel coil on the No. 0 saddle, the first rangefinder and the second rangefinder are used to monitor both sides of the steel coil, the walking beam, the detector, the first rangefinder and the second rangefinder are all connected to the controller, the detector, the first rangefinder and the second rangefinder transmit the information of the monitored steel coil to the controller, and the controller is used to control the start and stop of the walking beam.

[0006] In the above technical solution, a more specific technical solution may also be: a fence is provided at the No. 0 saddle, and the detector, the first rangefinder and the second rangefinder are provided on the fence.

[0007] Further: the fence includes a first railing, a second railing and a third railing, the detector is installed on the first railing by bolts, the first rangefinder is installed on the second railing by bolts, and the second rangefinder is installed on the third railing by bolts, which is easy to disassemble and assemble.

[0008] Furthermore: the detector, the first rangefinder and the second rangefinder are all laser rangefinders.

[0009] Further: the controller is a PLC controller.

[0010] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the detector first detects that there is a steel coil on the No. 0 saddle, and then after determining that the distance from the first rangefinder to one side of the steel coil and the distance from the second rangefinder to the other side of the steel coil are not much different, the controller controls the stepping beam to start working, effectively preventing the steel coil from tipping over due to the different weights on both sides.

[0013] The utility model is further described in detail below with reference to the accompanying drawings:

[0014] like Figure 1 The walking beam steel coil detection device shown in the figure includes a walking beam and a controller. A detector 1, a first distance meter 2 and a second distance meter 3 are arranged at the zero saddle 4 of the walking beam. The steel coil 5 is transported to the zero saddle 4. The detector 1 is used to monitor whether there is a steel coil 5 on the zero saddle 4. The first distance meter 2 and the second distance meter 3 are used to monitor the two sides of the steel coil 5. The walking beam, the detector 1, the first distance meter 2 and the second distance meter 3 are all connected to the controller. The detector 1, the first distance meter 2 and the second distance meter 3 The information of the steel coil 5 monitored is transmitted to the controller, which is used to control the start and stop of the walking beam; a fence 6 is provided at the zero saddle 4, and the detector 1, the first rangefinder 2 and the second rangefinder 3 are provided on the fence 6; the fence 6 includes a first railing 61, a second railing 62 and a third railing 63, the detector 1 is installed on the first railing 61 by bolts, the first rangefinder 2 is installed on the second railing 62 by bolts, and the second rangefinder 3 is installed on the third railing 63 by bolts, which is convenient for disassembly and assembly. The detector 1, the first rangefinder 2 and the second rangefinder 3 are all laser rangefinders; the controller is a PLC controller.

[0015] During operation, the coil unloading trolley transports the steel coil 5 from the coil receiving position of the coiler or the inspection table to the No. 0 saddle 4 of the walking beam. The detector 1 transmits the information that there is a steel coil 5 on the No. 0 saddle 4 to the PLC controller, and the PLC controller then determines the deviation value of the distance from one side of the steel coil 5 to the first distance meter 2 and the distance from the other side of the steel coil 5 to the second distance meter 3. In this example, when the deviation value is 0, the PLC controller controls the walking beam to start working. When the difference value is greater than 0, the PLC controller locks the walking beam to make it stop. After the position of the steel coil 5 needs to be manually adjusted, the PLC controller is manually controlled to unlock the walking beam.

[0016] It should be noted that the PLC controller provided by the present invention is a common device in the prior art. It only needs to be connected through the connection relationship given in the embodiment of the present invention. The conventional setting of the PLC controller can obtain the technical solution of the present invention, which does not involve any improvement in control methods and software. As for the parameter setting and use method of the PLC controller, those skilled in the art can purchase the PLC controller and refer to the accompanying instruction manual to achieve the corresponding control setting, which will not be explained in detail here.
