Description

Technical Field

[0001] The invention belongs to the technical field of steel processing, and in particular relates to a double-core rod signal receiving and transmitting device. Background Art

[0002] In the daily production process, due to the large vibration amplitude of mechanical equipment, the signal is often lost, resulting in the double-core rod not receiving the stop signal and continuing to move upward, delaying production. For this reason, a lifting transmission device is installed next to the original signal sensor. The movement of the lifting device is transmitted by the original lifting device. At the same time, another signal sensor is added to the original signal sensor as a double insurance, which effectively solves the problem of loss of large vibration signals of the double-core rod. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a dual-core rod signal receiving and transmitting device to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dual-core rod signal receiving and transmitting device, including a support frame and a dual-core rod device, and also including:

[0005] A vertical support, slidably matched with a first limiting sliding groove provided on the support frame, for installing and placing the double core rod device;

[0006] A lifting assembly is installed on the support frame and is used to push the vertical support to drive the double core rod device to perform linear movement in the vertical direction;

[0007] The signal detector A is installed on the support frame and is used to detect the position of the double core rods, and is a photoelectric sensor A;

[0008] The information detection mechanism is installed on the support frame and is used to perform a replacement detection after the signal detector A fails to detect.

[0009] On the basis of the above technical solution, the present invention also provides the following optional technical solution:

[0010] Further technical solution: The information detection mechanism includes a telescopic block, a cylinder, a push rod and a signal detector B. The telescopic block slides with the cylinder fixedly connected to the support frame. The signal detector B is installed under the signal detector A and fixedly connected to the support frame. The push rod is fixedly connected to the vertical support and slides with the second limiting groove provided on the support frame. The cylinder passes through the support frame and the cylinder. The cylinder slides with the support frame. The signal detector B is a photoelectric sensor B.

[0011] Further technical solution: The lifting assembly includes a motor, a rotating shaft and a sprocket pair. The two rotating shafts are rotatably mounted on the support frame and are connected through the sprocket pair. The rotating shaft at the bottom is connected to the output shaft of the motor detachably mounted on the support frame.

[0012] Further technical solutions also include a fine-tuning control system for accurately adjusting the position of the double-core rod device.

[0013] Further technical solution: The fine-tuning control system includes:

[0014] An information collection module is used to detect the number of rotations of the rotating shaft, the movement position of the telescopic block, and the position of the double-core rod device;

[0015] An information processing module, used to process the information collected by the information collection module and generate control information for controlling the lifting component;

[0016] The control module is used to receive the control signal generated by the signal processing module and control the lifting component according to the control signal.

[0017] Further technical solution: The information collection module includes:

[0018] Position detection unit A, used for detecting the position of the double core rods, is a photoelectric sensor A;

[0019] The position detection unit B is used to detect the position of the telescopic block and is a photoelectric sensor B;

[0020] The rotation number detection unit is used to detect the rotation number of the rotating shaft, and is a counter;

[0023] Further technical solution: The pressure sensor is installed between the upright support and the double-core rod device to detect the weight of the double-core rod device.

[0024] Further technical solution: The specific working principle of the fine-tuning control system is:

[0025] S1. When the pressure sensor reaches the pressure threshold value A, the lifting assembly drives the vertical support to perform linear motion in the vertical direction along the length direction of the support frame, and at the same time, the vertical support pushes the push rod to push the telescopic block to perform linear motion in the vertical direction along the length direction of the cylinder;

[0026] S2, the position detection unit A detects the position of the double core rod device and transmits it to the signal processing module to generate a control signal for closing the lifting component;

[0027] S3. If the position detection unit A is in a state where the mechanical equipment vibrates with a large amplitude and the signal is lost, the signal unit B detects the position of the telescopic block, indicating that the dual-core rod device has initially reached the preset position;

[0028] S4, the distance detection unit and the number of turns detection unit perform corresponding detection on the displacement distance of the telescopic block and the number of turns of the rotating shaft, obtain the distance information and the number of turns information, and import them into the information processing module for processing, the information processing module performs dimensionless processing on the obtained number of turns information and distance information and imports them into the lifting component stop model to output the stop coefficient, if the obtained stop coefficient is compared with the preset stop threshold, if the obtained stop coefficient is not within the stop threshold, the distance information and the number of turns information are adjusted until the stop coefficient is within the stop threshold, thereby forming a control signal for controlling the lifting component to stop, at this time the control module receives the stop signal to stop the lifting component, wherein the stop model is expressed as:

[0029]

[0030] Wherein, TZ(S,Q) represents the stop coefficient, S represents the distance information, Q represents the number of laps information, α represents the influence factor of the distance information, and β represents the influence factor of the number of laps information;

[0031] S5. After the transfer of the dual-core rod device is completed, the pressure information obtained by the weight detection unit is reset, and the information processing module generates control information for resetting the lifting component. At this time, the control module receives the control information and starts the lifting component to reset the dual-core rod device.

[0032] The present invention provides a dual-core signal receiving and transmitting device, which has the following advantages compared with the prior art:

[0033] Beneficial effects:

[0034] 1. The lifting component drives the vertical support to drive the double-core rod device to perform linear movement in the vertical direction. At this time, the signal detector A detects that the double-core rod device has reached the position, and the lifting component stops working. After the signal detector A fails due to external vibration, the push rod in the information detection mechanism as a backup information detection moves synchronously under the push of the vertical support. The push rod further pushes the telescopic block to perform lifting and lowering movements. At this time, the signal detector B detects the position of the telescopic block, which indicates that the double-core rod device has moved to the preset position. At this time, the lifting component is shut down to complete the transfer processing of the double-core rod device in the vertical direction;

[0035] 2. The present invention can precisely control the position of the dual core rods through a fine-tuning control system even when the signal detector A fails due to external vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0043] See also Figure 1 to Figure 4 , provided in one embodiment of the present invention, is a dual-core signal receiving and transmitting device, comprising a support frame 1 and a dual-core device, and further comprising:

[0044] The vertical support 2 is slidably matched with a first limiting slide groove (not shown in the figure) provided on the support frame 1, and is used for installing and placing the double core rod device;

[0045] The lifting assembly 3 is installed on the support frame 1 and is used to push the vertical support 2 to drive the double core rod device to perform linear movement in the vertical direction;

[0046] The signal detector A4 is installed on the support frame 1 and is used to detect the position of the double core rods, and is a photoelectric sensor A;

[0047] An information detection mechanism, mounted on the support frame 1, is used to perform a replacement detection after the signal detector A4 fails to detect;

[0048] Among them, the information detection mechanism includes a telescopic block 501, a cylinder 502, a push rod 503 and a signal detector B504. The telescopic block 501 slides with the cylinder 502 fixedly connected to the support frame 1. The signal detector B504 is installed below the signal detector A4 and is fixedly connected to the support frame 1. The push rod 503 is fixedly connected to the vertical support 2 and slides with the second limiting groove (not marked in the figure) provided on the support frame 1. The cylinder 502 passes through the support frame 1 and the cylinder 502. The cylinder 502 slides with the support frame 1. The signal detector B504 is a photoelectric sensor B.

[0049] Among them, the lifting component 3 includes a motor 301, a rotating shaft 302 and a sprocket pair 303. The two rotating shafts 302 are rotatably installed on the support frame 1 and are connected through the sprocket pair 303. The rotating shaft 302 at the bottom is connected to the output shaft of the motor 301 detachably installed on the support frame 1. The motor 301 drives the rotating shaft 302 to rotate in the horizontal direction. At this time, the sprocket pair 303 rolls in the horizontal direction under the action of the two rotating shafts 302. At this time, the sprocket pair 303 pushes the vertical support 2 fixedly connected thereto to perform linear movement in the vertical direction along the length direction of the support frame 1.

[0050] In an embodiment of the present invention, the lifting component 3 drives the vertical support 2 to drive the dual-core rod device 6 to perform linear movement in the vertical direction. At this time, the signal detector A4 detects that the dual-core rod device 6 has reached the position, and the lifting component 3 stops working. After the signal detector A4 fails due to external vibration, the push rod 503 in the information detection mechanism serving as a backup information detection moves synchronously under the push of the vertical support 2. The push rod 503 further pushes the telescopic block 501 to perform lifting and lowering movements. At this time, the signal detector B504 detects the position of the telescopic block 501, which indicates that the dual-core rod device has moved to the preset position. At this time, the lifting component 3 is shut down to complete the transfer processing of the dual-core rod device in the vertical direction.

[0051] See also Figures 1 to 3 As an embodiment of the present invention, it also includes a fine-tuning control system for accurately adjusting the position of the double-core rod device, including:

[0052] An information collection module is used to detect the number of rotations of the rotating shaft 302, the movement position of the telescopic block 501, and the position of the double core rod device;

[0053] An information processing module, used to process the information collected by the information collection module and generate control information for controlling the lifting component 3;

[0054] A control module, used to receive the control signal generated by the signal processing module and control the lifting component 3 according to the control signal;

[0055] Wherein, the information collection module includes:

[0056] Position detection unit A, used for detecting the position of the double core rods, is a photoelectric sensor A;

[0057] The position detection unit B is used to detect the position of the telescopic block 501 and is a photoelectric sensor B;

[0058] A rotation number detection unit, used to detect the rotation number of the rotating shaft 302, which is a counter;

[0059] The weight detection unit is used to detect the gravity information borne by the support 2, and is a pressure sensor;

[0060] The distance detection unit is used to detect the movement distance of the telescopic block 501 and is a distance sensor.

[0061] Preferably, the pressure sensor is installed between the upright support 2 and the double core rod device 6 to detect the weight of the double core rod device 6;

[0062] The specific working principle of the fine-tuning control system is as follows:

[0063] S1. When the pressure sensor reaches the pressure threshold value A, the lifting assembly 3 drives the vertical support 2 to perform linear motion in the vertical direction along the length direction of the support frame 1, and at the same time, the vertical support 2 pushes the push rod 503 to push the telescopic block 501 to perform linear motion in the vertical direction along the length direction of the cylinder 502;

[0064] S2, the position detection unit A detects the position of the double core rod device and transmits it to the signal processing module to generate a control signal for closing the lifting component 3;

[0065] S3. If the position detection unit A is in a state where the mechanical equipment vibrates with a large amplitude and the signal is lost, the signal unit B detects the position of the telescopic block 501, indicating that the dual-core rod device has initially reached the preset position;

[0066] S4, the distance detection unit and the number of turns detection unit perform corresponding detection on the displacement distance of the telescopic block 501 and the number of turns of the rotating shaft 302, obtain the distance information and the number of turns information, and import them into the information processing module for processing. The information processing module performs dimensionless processing on the obtained number of turns information and distance information and imports them into the stop model of the lifting component 3 to output the stop coefficient. If the obtained stop coefficient is compared with the preset stop threshold, if the obtained stop coefficient is not within the stop threshold, the distance information and the number of turns information are adjusted until the stop coefficient is within the stop threshold, thereby forming a control signal for controlling the lifting component 3 to stop. At this time, the control module receives the stop signal to stop the lifting component 3, wherein the stop model is expressed as:

[0067]

[0068] Wherein, TZ(S,Q) represents the stop coefficient, S represents the distance information, Q represents the number of laps information, α represents the influence factor of the distance information, and β represents the influence factor of the number of laps information;

[0069] S5. After the transfer of the dual-core rod device is completed, the pressure information obtained by the weight detection unit is reset. At this time, the information processing module generates control information for resetting the lifting component 3. At this time, the control module receives the control information and starts the lifting component 3 to reset the dual-core rod device.
