Description

Technical Field

[0001] This application belongs to the field of mixed-rail vehicle technology, specifically relating to a mixed-rail vehicle cover device with a maintenance junction box. Background Technology

[0002] The molten iron car cover device is used to cover the molten iron car during the transportation of molten iron. It can significantly reduce the heat loss of molten iron during transportation and waiting, and effectively reduce the emission of pollutants such as smoke and dust into the atmosphere. For example, the molten iron car cover device disclosed in Chinese patents with application numbers CN202310035770.9 and CN202310034874.8.

[0003] Figure 6 A schematic diagram of a conventional iron-mixed car cover device is shown. The iron-mixed car includes two traveling mechanisms 63, each with an active end 62 and a driven end 64. A tank body 61 is positioned between the active end 62 and the driven end 64. A cover device 1 is mounted on the top of the active end 62. An electrical control box 2 and an operation box 4 are also mounted on one side of the traveling mechanism 63 of the active end 62. The electrical control box 2 contains an electrical control device and a battery pack 3 connected via a control cable 16 and a power cable 17. The cover device 1 is connected to the electrical control device via the control cable and the power cable. The control device consists of various electrical components, connected by control cables or power cables, and is powered by battery pack 3. It undertakes the control task of the entire covering device 1. The operation box 4 is equipped with an operating device connected to the electrical control device via control cables. The operating device consists of various buttons and indicator lights, etc., used to send control signals to the electrical control device in the electrical control box 2 and to provide feedback on the operation status of the covering device through indicator lights, etc. It also performs precise covering or uncovering operations on the covering device through the electrical control device to ensure the normal operation of the covering device.

[0004] Therefore, cables (control cables and power cables) play a crucial role in the covering device. They connect the various electrical components, control boxes, and operation boxes of the covering device, and are responsible for transmitting power and control signals. They are the key link for the coordinated work between various components.

[0005] However, because the cover device and the electrical control box are connected by a complete set of control and power cables, when maintenance is required on the running gear of the mixed-rail car, the car must be separated. According to the traditional mixed-rail car maintenance procedure, the connecting cables of the cover device must be disconnected before any further maintenance work can proceed. The specific steps include: first, disconnecting and pulling out the cable on one side of the electrical control box; then, pulling the cable out of the cable tray and securing it to the cover device. After maintenance, the cable needs to be re-laid in the cable tray and threaded into the electrical control box for wiring. This process is time-consuming and labor-intensive. Furthermore, due to the fast production pace and high turnover requirements of mixed-rail cars, the time available for maintenance on each off-line mixed-rail car is very limited. This traditional maintenance method results in a large workload, long operation time, low efficiency, and seriously affects production progress.

[0006] In view of the above-mentioned defects, the creators of this application have obtained the technical solution of this application after a long period of research and practice. Utility Model Content

[0007] This application provides a cover device for a mixed-rail car with a maintenance junction box. The maintenance junction box is set between the cover device and the electrical control box to connect the cables of the two, which effectively improves the maintenance efficiency of the mixed-rail car.

[0008] The technical solution to the technical problem solved in this application is as follows:

[0009] This application provides a cover device for a mixed-steel car equipped with a maintenance junction box. The mixed-steel car includes two traveling mechanisms, each with an active end and a driven end. A tank body is located between the active and driven ends. A cover device is located on the top of the active end. An electrical control box and an operating box are also located on the traveling mechanism on one side of the active end. The electrical control box contains an electrical control device and a battery pack connected by control cables and power cables. The operating box contains an operating device connected to the electrical control device by a control cable. A maintenance junction box is located outside the active end. The maintenance junction box is equipped with a heavy-duty connector socket for control cables and a heavy-duty connector socket for power cables. The cover device is connected to the heavy-duty connector socket for control cables and the heavy-duty connector socket for power cables via control cables and power cables, respectively. The electrical control device is connected to a heavy-duty connector plug for control cables and a heavy-duty connector plug for power cables via control cables and power cables, respectively. The heavy-duty connector plug for control cables and the heavy-duty connector plug for power cables are plugged into the heavy-duty connector socket for control cables and the heavy-duty connector socket for power cables, respectively.

[0010] Furthermore, the heavy-duty connector socket for the control cable and the heavy-duty connector socket for the power cable are respectively installed through the bottom of the maintenance junction box. The bottom of the maintenance junction box is also provided with multiple glands. The control cable and the power cable on the cover device pass through the glands and are connected to the heavy-duty connector socket for the control cable and the heavy-duty connector socket for the power cable.

[0011] Furthermore, the maintenance junction box has a cabinet door on the front and a terminal block on its inner side. The control cable and power cable on the cover device pass through the gland and are connected to the terminals on the terminal block. Each terminal is connected to the corresponding terminal on the control cable heavy-duty connector socket and the power cable heavy-duty connector socket via the control cable or the power cable. The electrical control device is connected to the corresponding terminal on the control cable heavy-duty connector plug and the power cable heavy-duty connector plug via the control cable and the power cable heavy-duty connector plug, respectively.

[0012] Furthermore, the top of the maintenance junction box is equipped with a rainproof cap.

[0013] Furthermore, the control cable heavy-duty connector socket and the power cable heavy-duty connector socket are provided with buckles on the outside.

[0014] Furthermore, there are two control boxes, which are respectively located on both sides of the traveling mechanism.

[0015] Furthermore, the maintenance junction box is made of stainless steel.

[0016] Compared with the prior art, the mixed-rail car cover device with maintenance junction box described in this application has a simple structure and is easy to manufacture and implement. By setting up the maintenance junction box, the control cable and power cable between the mixed-rail car cover device and the electrical control box are connected at the maintenance junction box through heavy-duty connectors. When the mixed-rail car is off the line for maintenance, the cover device and the traveling mechanism can be quickly separated by quickly plugging and unplugging the heavy-duty connector plug and socket, which effectively reduces the workload of mixed-rail car maintenance and improves the flexibility and efficiency of mixed-rail car maintenance.

[0025] Please see Figure 6The existing mixed-rail vehicle cover device shown includes two traveling mechanisms 63 for the vehicle's movement and support. One traveling mechanism 63 has an active end 62, and the other traveling mechanism 63 has a driven end 64. A tank 61 is located between the active end 62 and the driven end 64. The tank 61 can tilt under the action of the active end 62 and the driven end 64. A can opening is located at the center of the top of the tank 61. A cover device 1 is located on the top of the active end 62 for covering or uncovering the can opening. An electrical control box 2 and an operation box 4 are also provided on the traveling mechanism 63 on one side of the active end 62. The electrical control box 2 contains an electrical control device 21 and a battery pack 3 connected by a control cable 16 and a power cable 17. The capping device 1 is connected to the electronic control device via control cables and power cables. The electronic control device consists of various electrical components, which are connected to each other via control cables or power cables and together with the battery pack 3, form a control circuit and a power circuit. The battery pack 3 provides control power and power, and undertakes the control tasks of the entire capping device 1. The control box 4 contains an operating device 41 connected to the electronic control device 21 via control cable 16. The operating device 41 consists of various buttons and indicator lights, etc., and is used to send control signals to the electronic control device 21 in the control box 2 and to provide feedback on the operation status of the capping device through the indicator lights, etc. It also performs precise capping or uncapping operations on the capping device 1 through the electronic control device 21 to ensure the normal operation of the capping device.

[0026] Because the control cable and power cable between the cover device 1 and the electrical control box 2 are directly connected, it is inconvenient to separate the car from the platform during maintenance of the mixed-rail car after it is taken off the production line. Therefore, this application provides a mixed-rail car cover device with a maintenance junction box, such as... Figure 1-5 As shown, the innovation of this application lies in the addition of a maintenance junction box 5, which can be installed outside the active end 62. A control cable heavy-duty connector socket 142 and a power cable heavy-duty connector socket 144 are installed on the maintenance junction box 5. Each electrical component of the covering device 1 is connected to the corresponding control cable heavy-duty connector socket 142 and power cable heavy-duty connector socket 144 via control cables 16 and power cables 17. The electrical control device 21 is connected to the control cable heavy-duty connector plug 141 and power cable heavy-duty connector plug 143, which are compatible with the control cable heavy-duty connector socket 142 and power cable heavy-duty connector socket 144, via control cables 16 and power cables 17. The control cable heavy-duty connector plug 141 and power cable heavy-duty connector plug 143 are respectively inserted into the control cable heavy-duty connector socket 142 and power cable heavy-duty connector socket 144.

[0027] In this embodiment, the control cable heavy-duty connector plug 141 and control cable heavy-duty connector socket 142, and the power cable heavy-duty connector plug 143 and power cable heavy-duty connector socket 144 respectively constitute the control cable heavy-duty connector and the power cable heavy-duty connector, so that the maintenance junction box 5 can serve as an important transfer station for the cable connection between the cover device 1 and the electrical control box 2. When the traveling mechanism 63 of the mixed-rail car needs maintenance, the control cable heavy-duty connector plug 141 and the power cable heavy-duty connector plug 143 can be quickly unplugged from the control cable heavy-duty connector socket 142 and the power cable heavy-duty connector socket 144 respectively, and then the car platform can be separated and the traveling mechanism can be maintained. After the traveling mechanism maintenance is completed, the control cable heavy-duty connector plug 141 and the power cable heavy-duty connector plug 143 can be quickly plugged back into the corresponding control cable heavy-duty connector socket 142 and the power cable heavy-duty connector socket 144 to realize the connection of the control cable and power cable between the cover device 1 and the electrical control box 2.

[0028] In a preferred embodiment, the control cable heavy-duty connector socket 142 and the power cable heavy-duty connector socket 144 are respectively installed through the bottom of the maintenance junction box 5. The two sockets can be connected to the housing of the maintenance junction box 5 by bolts. Multiple glands 13 are also installed through the bottom of the maintenance junction box 5. The control cable 16 and the power cable 17 on the cover device 1 pass through the glands 13 and are connected to the corresponding terminals of the control cable heavy-duty connector socket 142 and the power cable heavy-duty connector socket 144.

[0029] In a preferred embodiment, the maintenance junction box 5 has a cabinet door 11 on the front, facilitating quick opening and maintenance by maintenance personnel. A terminal block 15 is located inside the junction box 5. The control cable 16 and power cable 17 on the cover device 1 pass through the gland 13 and connect to the terminals on the terminal block 15. Each terminal is then connected to the corresponding terminals on the control cable heavy-duty connector socket 142 and power cable heavy-duty connector socket 144 via the control cable 16 or power cable 17, achieving electrical connection. The electrical control device 21 is connected to the corresponding terminals on the control cable heavy-duty connector plug 141 and power cable heavy-duty connector plug 143 via the control cable 16 and power cable 17, respectively. The terminal block 15 facilitates the connection of various cables, ensuring reliable connections, while also simplifying inspection and maintenance.

[0030] As a preferred embodiment, the housing of the maintenance junction box 5 is made of 304 stainless steel, which has good corrosion resistance and can adapt to harsh outdoor environmental conditions. The overall protection level reaches IP55, which can effectively prevent dust from entering and resist a certain degree of water splash, ensuring the normal operation of internal electrical components.

[0031] As a preferred embodiment, the top of the maintenance junction box 5 is provided with a rain cap 12. The rain cap 12 can be double-sloped, which can guide rainwater to flow down smoothly, prevent rainwater from accumulating and seeping into the interior of the maintenance junction box, thereby further enhancing its waterproof performance.

[0032] In a preferred embodiment, the housings of the control cable heavy-duty connector plug 141, power cable heavy-duty connector plug 143, control cable heavy-duty connector socket 142, and power cable heavy-duty connector socket 144 are made of cast aluminum and treated with high-temperature powder coating, providing excellent corrosion and oxidation resistance. They can withstand frequent plugging and unplugging operations, ensuring long-term reliability. The control cable heavy-duty connector socket 142 and power cable heavy-duty connector socket 144 are equipped with stainless steel clips on their outer sides, which tightly secure the plug after connection, ensuring connection stability. Even during vibration or accidental collisions during the operation of the mixed-rail vehicle, the connection will not detach. When the clips are in the interlocked state, the protection level reaches IP65, better adapting to harsh working environments. The plugs and sockets of the heavy-duty connectors use high-quality insulating materials with excellent aging and wear resistance, further improving the durability and reliability of the cable system.

[0033] As a preferred embodiment, there are two operation boxes 4, which are respectively located on both sides of the traveling mechanism 63 for easy operation.
