Description

Technical Field

[0001] This application relates to the field of power transmission and transformation engineering design and construction, and in particular to a wire rope breakage clamping device and method for overhead line traction. Background Technology

[0002] With the increasing speed and quality of ultra-high voltage (UHV) power transmission projects in my country, construction safety has become a growing concern. In tension power line construction, the increased traction force makes safety and reliability a crucial research topic. Various safety faults are common in tension power line construction, with damage and breakage of the traction wire rope posing the greatest risk. Factors affecting the traction force of the wire rope include the overturning of the laying guide plate, jamming of the laying rotating connector, wire rope or conductor jumping out of its groove, loosening of the bending connector, and breakage of the conductor or traction rope. These accidents can cause damage to conductors and machinery, or even power outages and personal injury. Therefore, timely prevention of wire rope breakage and line slippage is extremely important.

[0003] Because a single section of tension cable laying can be 5-8 km long, and many sections are located in high mountainous areas, the location and time of cable breakage are difficult to determine, and these breaks often occur instantaneously. The cable's movement in the air is complex and difficult to monitor in real time, making it difficult to lock in place when a break occurs. While some power transmission and transformation companies in China have conducted research on preventing cable breakage, most of this research focuses on mechanical or unidirectional specialized mechanisms, whose reliability and applicability do not yet meet the general requirements of tension cable laying. Summary of the Invention

[0004] The present invention addresses the shortcomings of the prior art by proposing a wire rope clamping device and method for overhead line traction, which aims to clamp the traction rope after it breaks during the overhead line traction process to prevent the rope from being flung and causing accidents, thereby ensuring safe operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a wire breakage clamping device for overhead line traction steel wire rope, characterized in that it includes: a tension acquisition module, a traction plate data acquisition module, and a traction plate auxiliary communication module mounted on the traction plate; a color recognition module, a central control module, a main communication module, a servo motor, an electromagnetic push rod, a rotating platform, and a brake pin mounted on the pulley; and a data display module and a data display auxiliary communication module mounted on the traction machine and tension machine.

[0007] The head of the tension acquisition module is connected to one end of the traction rope in the groove of the trolley wheel; the other end of the traction rope is connected to the traction machine; the tail of the tension acquisition module is installed on the head of the traction plate; the tail of the traction plate is connected to one end of the wire; the other end of the wire is connected to the tension machine; the tension acquisition module is used to acquire the tension value of the traction rope and send it to the traction plate data acquisition module.

[0008] The auxiliary communication module of the traction plate is installed in the groove position in the middle of the traction plate, and is used to read the tension value collected by the traction plate data acquisition module and send it to the main communication module;

[0009] The main communication module is installed in the middle of the trolley crossbeam and is used to send the tension value to the central control module; the central control module sends the tension value to the data display secondary communication module;

[0010] The data display auxiliary communication module is installed on the operating panel of the traction machine and tension machine to receive data sent by the main communication module and send it to the data display module for display.

[0011] The color recognition module is installed on the inner side of the triangular plate of the front pulley of the trolley, and is used to detect the knot on the traction rope directly below and send the recognition signal to the central control module;

[0012] The rotating platform consists of two parts, left and right, with a slot in the middle of each part for the traction rope to pass through, and the size of the slot is smaller than the knot of the traction rope.

[0013] The central control module determines whether a knot in the traction rope is detected based on the recognition signal output by the color recognition module. If so, it sends a rotation command to the servo motor to rotate. The servo motor drives the rotating platform to rotate through a reduction gear, so that the rotating platform rotates from a horizontal position to a vertical position, allowing the knot in the traction rope to pass through the rotating platform. After the knot in the traction rope passes through the rotating platform, the servo motor rotates in the opposite direction to return to its original position; otherwise, the servo motor does not rotate.

[0014] The brake pins are located on both sides of the slots in the left and right parts of the rotating platform and are in a tightened state; electromagnetic push rods are provided at the ends of the brake pins.

[0015] The central control module determines whether the tension of the traction rope exceeds the set threshold. If so, it indicates that the traction rope is broken, and immediately powers on the electromagnetic push rod, causing the electromagnetic push rod to push the brake pin out to clamp the broken traction rope; otherwise, the electromagnetic push rod is not powered on.

[0016] The data display module also displays the power-on status of the electromagnetic push rod and the junction recognition results of the color recognition module.

[0017] The present invention provides a method for clamping broken wire ropes for overhead line traction, which is characterized by being applied to a scenario consisting of a tension acquisition module, a traction plate data acquisition module, and a traction plate auxiliary communication module located on a traction plate; a color recognition module, a central control module, a main communication module, a servo motor, an electromagnetic push rod, a rotating platform, and a brake pin located on a trolley; and a data display module and a data display auxiliary communication module located on the traction machine and tension machine.

[0018] A triangular plate is installed directly above the trolley wheel, and a color recognition module is installed on one side of the triangular plate; the color recognition module is located directly above the traction rope.

[0019] A horizontal rotating platform is provided above the crossbeam of the trolley. The rotating platform consists of two parts, left and right, with a slot in the middle of each part for the traction rope to pass through. The size of the slot is smaller than the knot of the traction rope.

[0020] Brake pins in a tightened state are respectively provided on both sides of the slots in the left and right parts of the rotating platform, and electromagnetic push rods are respectively provided at the ends of the brake pins; the monitoring and clamping method includes the following steps:

[0021] Step 1: Perform network pairing between the main communication module, the traction board secondary communication module, and the data display secondary communication module. After completing the network pairing, test whether the data transmission and reception are normal.

[0022] Step 2: After the test data transmission and reception are normal, the traction machine pulls the traction rope forward; when the color mark near the knot of the traction rope passes the color recognition module, the central control module reads the recognition signal output by the color recognition module and controls the servo motor to rotate, so as to drive the reduction gear to drive the rotating platform to rotate from the horizontal position to the vertical position, so that the knot of the traction rope can pass through the rotating platform.

[0023] Step 3: Based on the distance the traction rope has moved and the distance between the color mark and the knot of the traction rope, determine whether the knot of the traction rope has completely passed the pulley. If so, control the servo motor to rotate in the opposite direction so that the rotating platform returns from the vertical position to the horizontal position.

[0024] Step 4: After all the knots of the traction rope have passed through the color recognition module, the color recognition module recognizes another color mark in front of the traction plate and controls the servo motor to rotate, so that the rotating platform returns from the horizontal position to the vertical position and remains in a vertical state to prevent the power transmission wire connected to the tail of the traction plate from rubbing against the rotating platform.

[0025] Step 5: During the movement of the traction rope, when the rotating platform is in a horizontal position, check whether the tension value of the traction rope in the central control module exceeds the set threshold. If so, it indicates that the traction rope is broken, and the electromagnetic push rod is immediately energized, so that the electromagnetic push rod pushes the brake pin to pop out, thereby clamping the broken traction rope and stopping the traction rope from moving; otherwise, the electromagnetic push rod is not energized.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention can monitor the tension of the traction rope and, when the traction rope breaks, use a clamping device to clamp the broken traction rope, preventing it from swinging after breaking and causing an accident, thereby reducing economic losses and improving project safety.

[0029] Figure 2 This is a schematic diagram of the logic block diagram of the present invention. Detailed Implementation

[0030] In this embodiment, as Figure 1 As shown, a wire rope breakage clamping device and method for overhead line traction utilizes technologies such as tension acquisition, color recognition, wireless data transmission, and real-time automatic control to ensure the entire tensioning and laying process is under safe and controlled conditions. This reduces construction facility costs, accelerates project progress, and improves project quality and safety. Specifically, the wire rope breakage monitoring and clamping device includes: a tension acquisition module, a traction plate data acquisition module, and a traction plate auxiliary communication module located on the traction plate; a color recognition module, a central control module, a main communication module, a servo motor, an electromagnetic push rod, a rotating platform, and a brake pin located on a pulley; and a data display module and a data display auxiliary communication module located on the traction machine and tension machine.

[0031] The head of the tension acquisition module is connected to one end of the traction rope inside the groove of the trolley wheel; the other end of the traction rope is connected to the traction machine. The tail of the tension acquisition module is installed on the head of the traction plate, and the tail of the traction plate is connected to one end of the wire, the other end of the wire is connected to the tension machine. The tension acquisition module is used to acquire the tension value of the traction rope and send it to the traction plate data acquisition module. The traction plate data acquisition module performs analog-to-digital conversion on the analog tension acquired by the tension acquisition module.

[0032] The secondary communication module of the traction plate is installed in the groove in the middle of the traction plate. It is used to read the tension value collected by the traction plate data acquisition module and send it to the main communication module.

[0033] The main communication module is installed in the middle of the trolley beam and is used to send the tension value to the central control module; the central control module sends the tension value to the data display secondary communication module.

[0034] The data display auxiliary communication module is installed on the control panel of the traction machine and tension machine to receive data sent by the main communication module and send it to the data display module for display.

[0035] The color recognition module is installed on the inner side of the triangle plate of the front pulley of the trolley. It is used to detect the red paint sprayed on the front surface of the knot on the traction rope directly below and send the recognition signal to the central control module.

[0036] The rotating platform consists of two parts, left and right, with a slot in the middle of each part for the traction rope to pass through, and the size of the slot is smaller than the knot of the traction rope.

[0037] The central control module determines whether a knot in the traction rope is detected based on the recognition signal output by the color recognition module. If so, it sends a rotation command to the servo motor to rotate. The servo motor drives the rotating platform to rotate through the reduction gear, so that the rotating platform rotates from a horizontal position to a vertical position, allowing the knot in the traction rope to pass through the rotating platform. After the knot in the traction rope passes through the rotating platform, the servo motor rotates in the opposite direction to return to its original position; otherwise, the servo motor does not rotate.

[0038] The brake pins are located on both sides of the slots in the left and right parts of the rotating platform and are in a tightened state; electromagnetic push rods are provided at the ends of the brake pins.

[0039] The central control module determines whether the tension of the traction rope exceeds the set threshold. If so, it indicates that the traction rope is broken, and immediately energizes the electromagnetic push rod, causing the electromagnetic push rod to push the brake pin out to clamp the broken traction rope. Otherwise, the electromagnetic push rod is not energized, thereby controlling the pop-out and retraction of the brake pin.

[0040] The data display module also shows the power-on status of the electromagnetic actuator and the connection recognition results of the color recognition module for relevant personnel to view.

[0041] In this embodiment, a method for securing a broken wire rope used for overhead line traction is described, such as... Figure 2 As shown, the specific steps are as follows:

[0042] Step 1: The main communication module, the traction board secondary communication module, and the data display secondary communication module are paired on the network. The ID number of the main communication module is set to 01, the ID number of the traction board secondary communication module is set to 02, and the ID number of the data display secondary communication module is set to 03. The data sending ID of the main communication module is set to 03, so that all the data of the main communication module is sent to the data display secondary communication module.

[0043] Set the data transmission of the traction board secondary communication module to 01 so that all data from the traction board secondary communication module is sent to the main communication module.

[0044] Step 2: The central control module controls the servo motor to rotate, causing the rotating platform to rotate to a horizontal position;

[0045] Step 3: The central control module controls the electromagnetic push rod to retract the brake pin to the standby position;

[0046] Step 3: Pass one end of the traction rope through the slot of the rotating platform and then place it in the groove in the middle of the front pulley of the trolley;

[0047] Step 7: Spray a 10cm length of red paint on the front 1 meter of all the joints of the traction rope;

[0048] Step 5: Place the part of the traction rope marked with red directly below the color recognition module, and then turn on the marking button of the color recognition module. The color recognition module will record the color information of the red mark.

[0049] Step 8: Begin releasing tension lines; the traction rope will begin to move forward at a constant speed.

[0050] Step 12: The central control module monitors the level changes of the color recognition module output in real time.

[0051] Step 13: The central control module transmits the trigger status of the collected color recognition module to the main communication module, and the main communication module sends the data to the secondary communication module for display.

[0052] Step 14: After the color recognition module detects the red mark, its output level changes from high to low, indicating that the traction rope connector is about to reach the rotating platform position. Upon receiving this signal, the central control module controls the servo motor to rotate the rotating platform from a horizontal position to a vertical position, allowing the traction rope connector to pass through the trolley.

[0053] Step 15: Based on the distance the traction rope has moved and the original distance of the traction rope joint as indicated by the color markings, the central control module can determine when the traction rope joint has completely passed the pulley. Once it is determined that the traction rope joint has completely passed the pulley, the central control module controls the servo motor to rotate in the opposite direction, causing the rotating platform to return from the vertical position to the horizontal position.

[0054] Step 16: The red mark at the traction rope joint is 10CM, and the red mark on the traction rope in front of the traction plate is 20CM. When the color recognition module recognizes the red mark, it outputs a low level to the central control module. After receiving the low level, the central control module starts timing and determines the length of the red mark on the traction rope based on the moving speed of the traction rope at this time, thereby recognizing the traction rope joint and the traction plate.

[0055] Step 18: Once the central control module detects the traction plate, it controls the servo motor to rotate, causing the rotating platform to rotate from a horizontal position to a vertical position, facilitating the passage of the traction plate through the trolley. After the traction plate passes, there is no more traction rope behind it, and the rotating platform remains in a vertical position.

[0056] Step 19: When the traction rope moves, the tension acquisition module collects the tension received by the traction rope and transmits the tension information to the traction plate data acquisition module.

[0057] Step 20: The traction board data acquisition module sends the data to the traction board secondary communication module, and the traction board secondary communication module wirelessly sends the data to the main communication module.

[0058] Step 21: After the central control module receives data from the traction board's secondary communication module via the main communication module, it determines whether the traction rope has broken. If the traction rope is determined to be broken, the central control module de-energizes the electromagnet, causing the brake pin to pop out via the electromagnetic push rod. The brake pin then clamps the traction rope, stopping its movement through friction. The information about the broken traction rope and the brake pin clamping the traction rope is then sent to the data display module for display.
