Description

Technical Field

[0001] The utility model relates to a control device, in particular to a sectioned power-off control device for the busbars of four large cars of a coke oven, belonging to the technical field of coke oven control. Background Art

[0002] The four major vehicles, coal loading cars, electric locomotives, coke blocking cars, and coke pushing cars, are powered by busbars. When a busbar short circuits or other faults occur, they must be disconnected for maintenance and repair. During these repairs, normal production must be maintained to the greatest extent possible.

[0003] The busbar runs through coke oven #1, #1 coal tower, #2 coke oven #3, #2 coal tower, and #4 coke oven. Within each coke oven, the busbar is divided into a power supply section, an operating section, and a maintenance section. Power is provided from the distribution room of the rolling stock substation at #1 and #2 coal towers. For the power supply section, #1 coal tower supplies power to the rolling stock equipment at coke ovens #1 and #2, while #2 coal tower supplies power to the rolling stock equipment at coke ovens #3 and #4. Power is drawn from the distribution room to the on-site power switch box. The wiring at the lower terminal of the switch box connects to the wiring terminals (center) on the busbar power supply section, supplying power to both ends. The cables are then connected to the next sectional switch box via the wiring terminals (left and right), enabling segmented power outages in the operating and maintenance sections.

[0004] When a fault occurs in the busbar of the power supply section, the power supply to the distribution room needs to be cut off before maintenance can be carried out. However, at this time, the entire busbar is in a power-off state, and the vehicle cannot operate normally, which in turn affects normal production and the completion of daily production tasks.

[0019] In order to elaborate on the technical solutions adopted by the present invention to achieve the predetermined technical purpose, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments, and the technical means or technical features in the embodiments of the present invention can be replaced without paying creative work. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0020] like Figure 1As shown, the utility model is a segmented power-off control device for the busbar of the four-car coke oven, comprising a power supply section busbar 1, a first segment busbar 2, a second segment busbar 3, a first segment connector 4, a second segment connector 5, a power supply section control switch 6, a first segment control switch 7 and a second segment control switch 8. One end of the power supply section busbar 1 is connected to one end of the first segment busbar 2 through the first segment connector 4, and the other end of the power supply section busbar 1 is connected to one end of the second segment busbar 3 through the second segment connector 5. One end of the power supply section control switch 6, the first segment control switch 7 and the second segment control switch 8 are connected to a power source, and the other end of the power supply section control switch 6 is connected to the middle terminal 9 of the power supply section busbar 1, the other end of the first segment control switch 7 is connected to the terminal of the first segment connector 4, and the other end of the second segment control switch 8 is connected to the terminal of the second segment connector 5.

[0021] like Figure 2 As shown, the first segment connector 4 and the second segment connector 5 respectively include a connector body 10, one end of the connector body 10 is provided with a first cavity, and the other end of the connector body 10 is provided with a second cavity, and the end of the power supply section busbar, the first segment busbar 2 or the second segment busbar 3 is inserted into the first cavity or the second cavity.

[0022] The first and second cavities contain four chute grooves that match the power supply section busbar 1, the first segment busbar 2, or the second segment busbar 3. The ends of the power supply section busbar 1, the first segment busbar 2, or the second segment busbar 3 are embedded in the four chute grooves and can slide along them. Thus, during installation, the four busbars (the power supply section busbar 1, the first segment busbar 2, or the second segment busbar 3) are inserted into the first and second cavities along the chute grooves, facilitating connection with the elastic terminals at the bottom of the cavities.

[0023] A first cover plate is provided on the upper side of the first cavity, and a second cover plate is provided on the upper side of the second cavity. Grooves parallel to the upper side are provided on both sides of the first cavity, and ridges matching the grooves are provided on both sides of the first cover plate. The first cover plate is slidably arranged in the groove of the first cavity via the ridges. Grooves parallel to the upper side are provided on both sides of the second cavity, and ridges matching the grooves are provided on both sides of the second cover plate. The second cover plate is slidably arranged in the groove of the second cavity via the ridges. With the cover plate having a sliding structure, after the power supply section busbar 1, the first segment busbar 2, or the second segment busbar 3 are installed in the first cavity and the second cavity, the first cover plate and the second cover plate are slidably arranged on the surfaces of the first cavity and the second cavity respectively to maintain the integrity and aesthetics of the surfaces of the first segment connector 4 and the second segment connector 5.

[0024] Four elastic terminals 11 are provided on the sides of the first and second cavities. These are U-shaped conductive metal springs whose size matches the ends of the power supply section busbar 1, the first segment busbar 2, or the second segment busbar 3. When the ends of the busbars of the power supply section busbar 1, the first segment busbar 2, or the second segment busbar 3 slide along the chute to the bottom of the first and second cavities, the ends of the busbars snap into the U-shaped openings of the elastic terminals 11. The elastic terminals are then connected to the upper and lower terminals of the first segment connector 4 or the second segment connector 5 via internal wires, facilitating connection to an external switch.

[0025] like Figure 3 As shown, an elastic mechanism is provided at the bottom of the elastic terminal 11 to provide elastic force for the elastic terminal facing the power supply section busbar 1, the first section busbar 2 or the second section busbar 3.

[0026] The elastic mechanism includes a sliding rod 12, a circular ring 13, and a spring 14. A blind hole 15 matching the circular ring 13 is formed on the side of the first and second cavities of the connector body 10. The circular ring 13 is sleeved on the outside of the sliding rod 12 and fixedly connected to the sliding rod 12. The circular ring 13 is arranged in the blind hole 15 and can slide back and forth along the axial direction of the blind hole 15. The outer end of the blind hole 15 is provided with an inwardly contracting ring plate structure to limit the circular ring 13 in the blind hole 15. One end of the sliding rod 12 is fixedly connected to the bottom of the elastic terminal 11. The spring 14 is sleeved on the other end of the sliding rod 12 and is located between the bottom of the blind hole 15 and the circular ring 13. Due to the problem of installation accuracy of the busbar, it is actually difficult to ensure that the ends of the four busbars are completely flush. The present invention adopts an elastic mechanism to enable the elastic terminal 11 to achieve a certain range of expansion and contraction, so that even if the terminals of the four busbars are not flush, it can be ensured that each elastic terminal 11 can maintain good contact with the busbar.

[0027] The connector body 10 is made of epoxy resin to ensure that the first segment connector 4 and the second segment connector 5 have good insulation performance.

[0028] By adopting the first segmented connector 4 and the second segmented connector 5 of the utility model, the segmented connector can ensure good insulation between the two sections of the busbar, and can serve as fixing parts at both ends of the busbar. After the fixing is completed, the segmented connector can also serve as a terminal for connection to the outside. There is no need to install additional terminals at both ends of the busbar, and the overall installation is more convenient and quick.

[0029] The utility model provides a segmented power-off control device for the busbars of the four large cars of a coke oven. When a fault occurs in the busbar of a power supply section, the busbar of the power supply section can be shut down individually, while the remaining segmented busbars can still operate normally, thereby maximizing the normal operation of the four large cars and ensuring the efficiency of production tasks. The utility model provides a segmented connector, which integrates the wiring terminals of the busbar to achieve the insulation connection and fixation of the busbar, and at the same time can provide a terminal structure for connecting the busbar to an external switch, thereby improving the insulation and making the connection and installation more convenient and quick.
