Description

Technical Field

[0001] This utility model relates to the field of engineering equipment, specifically to a fast-response and precisely positioned replaceable component cable protection device. Background Technology

[0002] In the field of engineering equipment technology, mobile equipment cable protection devices are crucial for ensuring the safety and stability of power cables during the operation of mobile equipment, and are essential for ensuring the stable operation of power systems and the safety of maintenance personnel. However, traditional mobile equipment cable protection devices have the following shortcomings in practical engineering: First, traditional mobile equipment cable protection devices cannot trigger the power unit to stop after detecting a break in the pulley wire rope, which may lead to the equipment continuing to operate in a faulty state, increasing safety hazards; second, traditional mobile equipment cable protection devices cannot identify and locate which specific wire rope segment broke, causing the line fault, which is inconvenient for maintenance personnel to troubleshoot and maintain; finally, the components used to protect each cable segment in traditional mobile equipment cable protection devices cannot be replaced individually after damage or reaching the end of their service life, which limits the flexibility of the device and increases maintenance costs. Based on this, this utility model provides a fast-response and accurately positioned replaceable component cable protection device. Utility Model Content

[0003] The purpose of this invention is to provide a fast-responding and precisely positioned replaceable component tow cable protection device. To achieve this objective, this invention employs the following technical solution:

[0004] A fast-response and precisely positioned replaceable component tow cable protection device includes a tow cable bracket, a tow cable trolley, a steel wire rope, and a cable. The tow cable trolley is hung on the tow cable bracket, and the tow cable trolleys are connected and pulled by the steel wire rope. The cable is dragged on the tow cable trolley and located below the steel wire rope. The cable and steel wire rope between every two tow cable trolleys form a double-layer wave shape. The device also includes a steel wire rope breakage detection device.

[0005] Preferably, the wire rope breakage detection device includes an insulated cable, with both ends of the insulated cable inserted between every two adjacent towing trolleys. The insulated cable is arranged in parallel with the wire rope and cable, and the length of the insulated cable is slightly longer than that of the wire rope, while the length of the cable is significantly longer than that of the insulated cable.

[0006] Preferably, the insulated cable connecting every two adjacent towing trolleys is sequentially connected to a control circuit including a circuit detection control module, a trip judgment control module, and a fault indication control module.

[0007] Preferably, each circuit detection and control module is composed of relays with normally closed contacts connected in parallel, and each relay with normally closed contacts can respond to the breakage of the wire rope between each pair of towing cable pulleys.

[0008] Preferably, the trip judgment control module consists of a relay with normally open contacts and a motor, wherein each relay with normally open contacts is connected in parallel and the relay with normally open contacts is connected in series with the motor.

[0009] Preferably, the fault indication control module comprises a relay with a normally open contact and a warning light, wherein the relay with each normally open contact and the warning light are connected in series.

[0010] Preferably, the wire rope breakage detection device can be quickly replaced when it is damaged or reaches the end of its service life.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. Timely shutdown protection: This device arranges insulated cables in each trolley interval and runs them in parallel with the steel wire rope. When the steel wire rope breaks, the insulated cable will be further pulled and break, thereby triggering the control circuit to achieve rapid shutdown and prevent the equipment from continuing to operate in a faulty state, effectively reducing safety hazards.

[0013] 2. Precise fault location: This device, by designing corresponding indicator lights or display devices in the control circuit, can intuitively reflect which section of the wire rope has broken, enabling maintenance personnel to quickly locate the fault, facilitating troubleshooting and maintenance work, and saving time and effort.

[0014] 3. Replaceable protection components: The insulated cables in this device are designed to be replaceable. When the insulated cables are damaged or reach the end of their service life, they can be quickly replaced individually without replacing the entire device. This reduces maintenance costs and time, and improves the flexibility and maintainability of the device. Attached Figure Description

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-2 The present invention will now be described in further detail.

[0020] like Figure 1 As shown, one embodiment of this utility model includes a cable support 1, a cable trolley 2, a steel wire rope 3, an insulated cable 4, and a cable 5. The cable support 1 is the fixed support structure for the entire device. The cable trolley 2 is mounted on the cable support 1. The two ends of the steel wire rope 3 are hooked between every two adjacent cable trolleys 2. The two ends of the insulated cable 4 are inserted between every two adjacent cable trolleys 2. The cable 5 is dragged along the cable trolley 2. The insulated cable 4 is arranged parallel to the steel wire rope 3 and the cable 5. The length of the insulated cable 4 is slightly greater than that of the steel wire rope 3, while the length of the cable 5 is significantly greater than that of the insulated cable 4. When the steel wire rope 3 breaks, the insulated cable 4 will be further pulled and break, thereby triggering the control circuit to stop the dragging device and illuminate an indicator light to show the specific breakage interval, preventing damage to the cable 5 and facilitating fault inspection by personnel.

[0021] like Figure 2 As shown, the system includes a circuit detection control module 6, a trip judgment control module 7, and a fault indication control module 8. The circuit detection control module 6 consists of relays 601 with normally closed contacts connected in parallel, used to determine the integrity of the wire rope 3. The trip judgment control module 7 consists of relays 701 with normally open contacts and a motor 702. The relays 701 with normally open contacts are connected in parallel, and each relay 701 with normally open contacts is connected in series with the motor 702. When a wire rope breakage is detected, the normally open contact of relay 701 closes, triggering the motor 702 to stop the drive device. The fault indication control module 8 consists of relays 801 with normally open contacts and warning lights 802. Each corresponding normally open relay 801 and each warning light 802 is connected in series, used to control whether the warning lights illuminate.

[0022] The specific working principle is as follows:

[0023] When the cable-dragging device of the mobile device is in normal operation, the wire rope 3 drives the cable-dragging trolley 2 to move on the cable-dragging bracket 1, thereby transporting the cable 5 through the cable-dragging trolley 2. During this process, each segment of insulated cable 4 maintains normal tension following the movement of the wire rope 3 without breaking. Under the action of the power supply, current flows through each segment of insulated cable 4 connected in series with the power supply. The relays 601 with normally closed contacts in the corresponding circuit detection control module 6 on each segment of insulated cable 4 are all energized. The normally open contacts of the relay 701 with normally open contacts in the trip judgment control module 7 are all open, and the motor 702 does not operate. The normally open contacts of the relay 801 with normally open contacts in the fault indication control module 8 are all open, and the corresponding warning lights 802 are all extinguished, without issuing a warning signal.

[0024] When a section of the steel wire rope 3 of the mobile device's towing cable device breaks, the broken section of steel wire rope 3 is no longer subject to the traction force of the sliding towing cable trolley 2. This causes the towing cable trolley 2 to continue sliding, resulting in the insulated cable 4 being pulled loose under the traction force of the towing cable trolley 2. The current generated by the power supply cannot pass through each section of the insulated cable 4. The normally closed contact of the relay 601 with the normally closed contact in the circuit detection control module 6 corresponding to the insulated cable 4 opens because there is no current passing through it. In the trip judgment control module 7, there is current passing through the normally open contact of the relay 701 corresponding to the broken section of steel wire rope 3, causing the corresponding normally open contact in the relay 701 to close, thereby triggering the motor 702 to operate and stop the towing device. In the fault indication control module 8, there is current passing through the normally open contact of the relay 801 corresponding to the broken section of steel wire rope 3, causing the corresponding normally open contact in the relay 801 to close, thereby illuminating the warning light 802 of the corresponding section and issuing a warning signal.

[0025] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the concept of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
