[0002] With the rapid development of the coking industry and increasingly stringent environmental protection requirements, the share of large-volume coke ovens in the coking field is increasing day by day. In the layout of the coke oven area, the dry coke quenching device is divided into two layout methods: conventional layout and dry coke quenching layout with transverse traction device. Among them, the dry coke quenching layout with transverse traction device has the advantages of saving inter-stage space and reducing civil engineering investment, so it is highly respected. However, for the 7.65m coke oven, due to the special structure of its coke interceptor, the electric locomotive busbar is arranged on the second track bracket of the coke interceptor, which interferes with the transverse traction device. To realize the transverse traction of the coke tank, the busbar structure needs to be improved. Summary of the invention

[0018] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0019] like Figure 1 , Figure 2 As shown, the present invention discloses an openable and closable busbar structure for a coke oven electric locomotive, comprising a busbar support 1, a busbar and a busbar rotating mechanism 3; the busbar support 1 is composed of a plurality of racks arranged at intervals, and a plurality of busbars are arranged on the busbar support 1 in parallel along the height direction; wherein the busbar between the two racks corresponding to the lateral displacement of the coke tank is an openable and closable busbar 2, and the openable and closable busbar 2 is split into two halves from the center, and the outer ends thereof are rotatably connected to the racks at the corresponding ends through the busbar rotating mechanism 3.

[0020] The busbar rotating mechanism 3 is composed of a driving motor, a rotating shaft and a rotating shaft support; the rotating shaft support is installed on the busbar bracket 1, the driving motor is arranged on the outside of the rotating shaft support, the rotating shaft is hinged to the rotating shaft support, the motor shaft of the driving motor is connected to the rotating shaft, an axial hole is provided on the openable and closable busbar 2 for the rotating shaft to pass through, and the openable and closable busbar 2 and the rotating shaft are connected by a key.

[0021] The busbar support 1 is provided with a control button 4, and the control button 4 is connected to the control end of each driving motor.

[0022] The busbar bracket 1 is provided with a signal transceiver and a controller 4, the signal transceiver is wirelessly connected to the signal sending device on the electric locomotive and the signal receiving device on the transverse traction device, and the signal transceiver is connected to the control end of each drive motor through the controller 4.

[0023] The busbar support 1 is arranged on the second track support 5 of the coke intercepting vehicle.

[0024] A Chinese patent application with application publication number CN 101735830 A discloses a "coke dry quenching transverse shift process", comprising the following steps: ① an electric locomotive is provided with a trolley, on which a coke drum with wheels filled with red coke is loaded; the electric locomotive drives the trolley to move along the quenching car track to the vicinity of the transverse shift track, and aligns the trolley with the transverse shift track through a positioning device; ② a traction mechanism is connected to the coke drum with wheels filled with red coke, and pulls the coke drum with wheels filled with red coke off the trolley; the lower part of the lifting shaft is a lifting position, and the traction mechanism pulls the coke drum with wheels to a position in front of the lifting position for waiting; ③ a hoist in the lifting shaft lowers another empty coke drum with wheels to the lifting position; ④ the traction mechanism pulls the coke drum with wheels filled with red coke close to the empty coke drum with wheels, and pushes the empty coke drum with wheels forward together, until the empty coke drum with wheels reaches the standby position behind the lifting position of the lifting shaft. , until the coke drum with wheels filled with red coke reaches the lifting position; ⑤ the traction mechanism is separated from the coke drum with wheels filled with red coke; at the same time, the hook of the hoist of the lifting shaft is lowered and connected with the coke drum with wheels filled with red coke, and the traction mechanism is connected with the empty coke drum with wheels; ⑥ after the hoist of the lifting shaft lifts the coke drum with wheels filled with red coke upward by a set distance, the traction mechanism pulls the empty coke drum with wheels to move toward the trolley, and places the empty coke drum with wheels on the trolley; ⑦ the electric locomotive pulls the trolley along the quenching car track in the opposite direction to the coke oven, and uses the empty coke drum with wheels to take over the red coke of the next oven; the empty coke drum with wheels becomes a red coke drum after being filled with red coke; the coke drum with wheels filled with red coke in step ⑥ continues to be lifted along the lifting shaft to the set position, and then the red coke is unloaded to become an empty coke drum; the red coke drum in step ⑦ undergoes a new round of work according to steps ① to ⑦ above.

[0025] The coke interceptor is usually a two-track type, one of which is set on the operating table on the coke side of the coke oven, and the second track is located on the steel structure of the coke pusher and dust collector. The two tracks are the running tracks of the coke interceptor. The electric locomotive busbar of the 7.65m coke oven is arranged on the second track bracket of the coke interceptor, which interferes with the transverse traction device.

[0026] The present invention is applied to the operation process of the coke oven vehicle. When the coke tank moves horizontally, the openable and closeable busbar is driven to open by the busbar rotating mechanism, so that the coke tank can smoothly pass through the electric locomotive busbar area under the horizontal traction device. The rest of the time, the openable and closeable busbar is always in a closed state. The opening and closing operation of the openable and closeable busbar can be selected manually (control button) or automatically (controller). Taking the automatic operation as an example, the opening and closing process of the openable and closeable busbar is specifically as follows:

[0027] like Figure 3 As shown, the coke tank carrier 7 that has completed the coke receiving operation carries the coke tank 8 to the transverse track (i.e., the coke tank is transversely shifted). After the alignment is completed, the signal sending device sends a signal to the signal transceiver on the busbar support 1. After receiving the signal, the signal transceiver controls each drive motor to act simultaneously through the controller 4, driving the openable and closeable busbar 2 to rotate and complete the opening action, and then sends a signal to the signal receiving device of the transverse traction device 9 through the signal transceiver. After receiving the signal, the transverse traction device 9 loaded with an empty coke tank performs a traction action and sends the empty coke tank to the coke tank carrier 7. After that, the coke tank carrier 7 is aligned again and sends the coke tank filled with coke to the transverse traction device 9, which is pulled to the lifting position by the transverse traction device 9 for lifting operation. After the transverse traction device 9 pulls the coke tank 8 out of the busbar area, it sends a signal to the signal transceiver again. After receiving the signal, the signal transceiver controls the drive motor through the controller 4 to drive the openable and closeable busbar 2 to fall back to the horizontal position. The coke tank carrier 7 continues to move along the busbar to complete the coke receiving work.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
