TECHNICAL FIELD
[0001] The present application relates to a driver's room and wiring structure in the driver's room, more particularly, it relates to a line guide structure of a metallurgical casting hoist driver's room and a control method thereof. BACKGROUND
[0002] The crane can be divided into five categories according to its moving mode, including fixed crane, climbing crane, portable crane, radial rotary crane and walking crane. At the same time, according to the driving mode of the crane, it can be divided into manual crane, electric crane and hydraulic crane.
[0003] Among them, the metallurgical crane is a key operating device for large-scale metallurgical production. The temperature inside the metallurgical plant is relatively high, and the normal operation of each device in the driver's room needs to be ensured during the operation of the driver's room. For example, the cooling device in the driver's room needs to be ensured to operate normally during operation, so as to prevent the temperature in the driver's room from being too high. At the same time, the air circulation device needs to circulate air to prevent workers from being short of oxygen. Therefore, during the line planning process of the driver's room, the stability of the line connection needs to be ensured to prevent the occurrence of open circuit during operation, which leads to production stagnation.
[0004] At present, the line arrangement of the crane driver's room on the market is usually to draw several wires from the power supply, and connect each wire with the device that needs to be powered. The starting position of the wire is usually concentrated in one point, which leads to difficult overall wiring. After a long time of use, the wire harness will be wound, which affects the subsequent maintenance of the wire harness and the detection of the broken point. At the same time, during use, the local temperature of the wire harness winding place will be too high, which will cause safety hazards. SUMMARY

[0012] The application also discloses a control method of a line guide structure of a metallurgical casting crane operator room, and the line guide method comprises the following steps: S1, opening a wire arrangement groove, and connecting a plurality of guide lines to corresponding positions of a cable bridge, wherein parameters of the guide lines are matched with devices to be powered, and a line for powering each device in the operator room is formed;
[0013] S2, after line guide is completed, based on positions of the devices to be powered, the guide lines are placed into corresponding wire arrangement grooves, and are guided out through corresponding wire outlet holes;

[0020] By adopting the technical scheme, the beneficial effects are achieved. The line guiding structure is arranged on the driver's cabin frame body to optimize the driver's cabin line. Specifically, the cable bridge is arranged in the installation top plate to effectively guide the external power supply. The wiring device formed by the wiring groove and the wire passing groove body disperses each line to each area of the driver's cabin and communicates with the equipment in the area. Each outgoing line is connected to the cable bridge arranged in a strip shape, avoiding the line winding caused by concentrated wiring. The cooling structure is arranged on the installation top plate to effectively cool the whole line. The wiring groove and the wire passing groove body are in communication, and part of the cold air at the cooling structure can pass through the wiring groove and the wire hole to cool the whole outgoing line and ensure that the cold air is discharged in multiple holes. After the line installation is completed, the signal output device and the detection loop can detect the connection and on-off state of each outgoing line in real time, so that the line guiding structure can guide the outgoing line, cool the wire harness during use, and synchronously detect the line state, realizing the safety and reliability of the whole line system of the driver's cabin, and reducing the difficulty of subsequent maintenance.
[0021] 2. Further, the wiring device is arranged, specifically, the wire passing groove body is arranged on the top of the driver's cabin frame body, and the wire passing groove body and the wiring groove are in communication. Multiple wire holes are arranged at one end of the wiring groove close to the inner side of the driver's cabin, so that the outgoing line forms a reasonable line channel in the wiring device, and the line drawn from the cable bridge can be distributed according to the preset channel, effectively preventing the winding and crossing of multiple outgoing lines. At the same time, the part of the cable bridge drawing each outgoing line is provided with a wire arranging groove to facilitate the drawing and subsequent maintenance of the line, optimize the line distribution layout, and improve the standardization of the line distribution and the portability of the subsequent maintenance.
[0022] 3. At the same time, the circulation device and the cooling structure are arranged, the cooling structure can output cold air to the driver's cabin, and part of the cold air enters the wiring device through the wire passing groove body to synchronously cool each outgoing line, preventing the line temperature from being too high. At the same time, the driver's cabin is also provided with an air outlet to effectively promote the circulation of air in the driver's cabin, avoid the risk of oxygen deficiency of personnel working in the driver's cabin for a long time, and maintain the temperature in the driver's cabin at a suitable working temperature. At the same time, the wiring device is arranged in the heat insulation device to effectively reduce the heat conduction from the outside of the driver's cabin to the inside of the driver's cabin. The service life of the outgoing line is prolonged, and the normal use of the driver's cabin in a high-temperature environment is ensured.
[0023] 4、And, when installing the line in the driver's room, the corresponding outgoing line is connected to the corresponding wiring slot through the wiring slot, forming the cable bridge to the nearest electrical equipment, reducing the consumption of cables during wiring. After the wiring of each device is completed, the signal output device provided on the cable bridge and the end of each outgoing line are connected to form a detection loop, and through the signal receiving components provided on the detection loop, a structure that can automatically detect the line state is formed. Specifically, the signal output device outputs an electrical signal for detection, and the signal receiving component detects the current signal. After detecting the current signal I, the current signal is converted into a voltage signal V. At the same time, based on the current detected device parameters, the current voltage signal detection value and the minimum voltage signal are set. Specifically, since the connection mode of each device is parallel, when there is current passing through the branch being detected (I>0), a significant voltage V will be generated at the signal receiving component. At this time, the voltage value V is higher than the voltage signal detection value, indicating that the current state of the line is on. Conversely, when the branch is disconnected or the device is damaged, the current I passing through the branch is 0, and the corresponding voltage value V=0 (or only a small noise). The value read is lower than the minimum voltage signal, and it is determined that the current branch is disconnected. By outputting the detection signal and collecting the current and voltage signals of each branch, the system can automatically determine the connection state of the line, quickly locate the abnormal line or device after detecting the abnormality, greatly reduce the troubleshooting time of the circuit abnormality, and obtain the specific fault reason through the detailed data of the detected voltage. Improve the efficiency of maintenance and ensure the operation reliability of the crane driver's room during continuous production. BRIEF DESCRIPTION OF DRAWINGS
