Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgy, and more specifically relates to an active anti-collision device for continuous casting steel-moving equipment. Background Art

[0002] Billets produced by continuous casting machines are typically stacked for cooling or delivered hot to a rolling mill. This is where steel transfer equipment plays a crucial role. These equipment include various types of scoopers, pushers, and transfer machines. The transfer equipment primarily consists of a main unit, along with guide rails and a travel mechanism. The transfer equipment moves along guide rails perpendicular to the roller conveyor's direction of travel, transferring billets from the discharge roller conveyor to a cooling bed or other roller conveyor.

[0003] Based on the above, the inventors discovered the following problem: As the steel moving equipment moves along the guide rails, the overhead crane may operate in its path, potentially colliding with fixtures or other equipment suspended from the overhead crane. Currently, when an obstacle appears in the steel moving equipment's path, the equipment cannot automatically determine whether it will collide with the obstacle, requiring the operator to manually operate the equipment to avoid a collision.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an active anti-collision device for continuous casting steel moving equipment is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the active anti-collision device for continuous casting steel transfer equipment of the utility model are achieved by the following specific technical means:

[0006] An active anti-collision device for continuous casting steel-moving equipment includes a steel-moving equipment main body, a traveling mechanism, a guide rail, a PLC control program, and an ultrasonic ranging sensor. The steel-moving equipment main body moves along the guide rail via the traveling mechanism. Ultrasonic ranging sensors are installed on both sides of the steel-moving equipment main body. The detection direction of the ultrasonic ranging sensor is the traveling direction of the steel-moving equipment main body. The PLC control program determines and controls the traveling, stopping, and deceleration actions of the steel-moving equipment main body through signals from the ultrasonic ranging sensor.

[0007] Furthermore, the ultrasonic ranging sensor can cover the width of the steel moving equipment body in the horizontal direction and the height of the steel moving equipment body in the vertical direction.

[0008] Furthermore, the PLC control program will determine whether there is an obstacle on the path of the steel moving equipment body according to the walking direction of the steel moving equipment body and the ultrasonic ranging sensor signal on the corresponding side.

[0009] Furthermore, both ends of the steel moving equipment body are connected to the traveling mechanism through connecting pieces.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model adds an ultrasonic distance sensor to steel moving equipment and connects the ultrasonic distance sensor signal to the equipment's PLC control program. This allows the equipment to automatically slow down and stop when an obstacle appears in its path, preventing a collision. Once the obstacle disappears, the equipment can resume its movement. This proactively prevents collisions even during automated operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As attached Figure 1 To the attached Figure 3 As shown:

[0021] The utility model provides an active anti-collision device for continuous casting steel-moving equipment, comprising a steel-moving equipment main body 1, a walking mechanism 5, a guide rail 4, a PLC control program, and an ultrasonic ranging sensor 2. The steel-moving equipment main body 1 moves along the guide rail 4 through the walking mechanism 5, and ultrasonic ranging sensors 2 are installed on both sides of the steel-moving equipment main body 1. The detection direction of the ultrasonic ranging sensor 2 is the walking direction of the steel-moving equipment main body 1, and the PLC control program judges and controls the walking, stopping, and deceleration actions of the steel-moving equipment main body 1 through signals from the ultrasonic ranging sensor 2.

[0022] The ultrasonic ranging sensor 2 can cover the width of the steel moving equipment body 1 in the horizontal direction and the height of the steel moving equipment body 1 in the vertical direction.

[0023] The PLC control program determines whether there are obstacles on the path of the steel moving equipment body 1 according to the walking direction of the steel moving equipment body 1 and the signal of the ultrasonic ranging sensor 2 on the corresponding side.

[0024] Wherein, both ends of the steel moving equipment body 1 are connected to the traveling mechanism 5 through connecting parts 3 .

[0025] The specific usage and function of this embodiment are as follows:

[0026] The following will take a steel moving device with a total length of 13.6m (the distance between the two tracks is 13.6m) as an example and combine with the drawings in the embodiment of the utility model to clearly and completely describe the technical solution in the embodiment of the utility model.

[0027] Two groups of ultrasonic ranging sensors 2 are installed on both sides of the steel moving equipment body 1 along the travel direction of the guide rail 4. The beam angle of the ultrasonic ranging sensor 2 is 30° (the detection angle is 60°), the measurement range is 10mm~2000mm, the measurement accuracy is ±2mm, and analog output is used. If 10 ultrasonic ranging sensors 2 are installed on each side, the required measurement range can be covered.

[0028] Furthermore, the ultrasonic distance measuring sensor 2 feedback value range Range1 (2000mm-1600mm) corresponding to the deceleration action of the steel moving equipment and the ultrasonic distance measuring sensor 2 feedback value range Range2 (1600mm-10mm) corresponding to the stop action of the steel moving machine are set in the PLC.

[0029] Furthermore, to determine whether the steel moving equipment body 1 is currently moving along the guide rail 4, the PLC reads the minimum signal value of the ten ultrasonic ranging sensors 2 in the moving direction in real time to make this determination. If the minimum signal value of the ten ultrasonic ranging sensors 2 falls within Range 1, the PLC control program within the steel moving equipment body 1 controls the steel moving equipment body 1 to slow down.

[0030] Furthermore, when the minimum value of the signal values of the ten ultrasonic distance measuring sensors 2 is in Range 2, the PLC control program inside the steel moving equipment body 1 controls the steel moving equipment to stop moving.

[0031] Furthermore, when the minimum signal value of the 10 ultrasonic ranging sensors 2 is neither within Range 1 nor within Range 2, the PLC control program inside the steel moving equipment body 1 controls the steel moving equipment body 1 to continue moving in the direction before stopping.

[0032] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
