Description

Technical Field

[0001] The utility model relates to the technical field of steel coil transportation, in particular to a novel busbar steel coil transportation system. Background Art

[0002] The busbar coil transport system is a new method for transporting hot-rolled steel coils. Compared to traditional pallet-type coil transport systems, it is more intelligent and offers substantial improvements in transport speed and length. However, during actual commissioning and application, this method still has some shortcomings. For example, busbar coil transport vehicles have certain requirements for the busbar. In areas where the busbar cannot be powered or where the terrain precludes the construction of a busbar, the busbar coil transport vehicle can only be moved by external force. This imposes certain restrictions on its operation and limits its scope of use. Utility Model Content

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0017] A new type of busbar steel coil transportation system, see Figure 1-Figure 2 , including: a busbar steel coil transport vehicle 1, a track 2 for the busbar steel coil transport vehicle to run, and a collector arm 3.

[0018] A plurality of busbars 2-1 are arranged in parallel on the side of the track 2. The collector arm 3 is fixedly connected to the busbar steel coil transport vehicle 1 and is used to collect the electrical energy of the busbar to power the operation of the busbar steel coil transport vehicle 1. A plurality of sliding contacts 3-1 are provided on the collector arm 3 for contacting the busbar 2-1.

[0019] The busbar steel coil transport vehicle 1 comprises a vehicle body 1-1, in which an electric control system is provided. Figure 3 The following is a detailed introduction to the electronic control system of the busbar steel coil transport vehicle.

[0020] The collector arm on the busbar steel coil transport vehicle (called a trolley) is connected to the transformer input terminal, and the three-phase electricity on the busbar is collected through the collector arm and stepped down by the transformer. The output terminal of the transformer is divided into four routes through the main circuit breaker QF0, among which the first three-phase electricity is connected to the motor fan M1 of the trolley through the first circuit breaker QF1 and the first contactor KM1; the second three-phase electricity is connected to the input terminal of the inverter through the second circuit breaker QF2, and the output terminal of the inverter is connected to the motor M2 of the trolley (motor M2 is the power source for driving the trolley); the neutral wire and one of the live wires in the third three-phase electricity are connected to a battery (24V) through the third circuit breaker QF3. The power supply terminal of the battery is connected to the PLC to power it. The battery has the function of automatic power-off when fully charged (batteries generally have this function, which is a conventional function, or can be understood as The battery here is together with the battery charging controller, and the battery charging controller enables the battery to have this function); the fourth three-phase electricity is connected to the fourth circuit breaker QF4 and divided into two branches, among which the first branch three-phase electricity of the fourth circuit breaker QF4 is connected to the AC end of the first AC-DC conversion device through the fifth circuit breaker QF5 and the second contactor KM2, and the DC end of the first AC-DC conversion device is connected to the charging end of the large-capacity battery for charging it; the second branch three-phase electricity of the fourth circuit breaker QF4 is connected to the AC end of the second AC-DC conversion device through the sixth circuit breaker QF6 and the third contactor KM3, and the DC end of the second AC-DC conversion device is connected to the discharge end of the battery. The discharge end of the battery can convert its DC into three-phase electricity through the second AC-DC conversion device, and then supply it to the fourth circuit breaker QF4 in the direction. The first contactor KM1, the second contactor KM2 and the third contactor KM3 are all connected to the PLC, and their on and off states are controlled by the PLC; in addition, a proximity switch is provided on the collector arm to detect whether the collector arm is in effective contact with the busbar, and the proximity switch is connected to the PLC.

[0021] Specifically, the operating principle of the busbar steel coil transport vehicle is as follows:

[0022] First, after the busbar steel coil transport vehicle (i.e. the trolley) is manually powered on at the starting position, the PLC controls the second contactor KM2 to be turned on, so that the battery is in a charging state; during the operation of the busbar steel coil transport vehicle, the PLC controls the first contactor KM1 to be turned on, turning on the motor fan M1, and at the same time the frequency converter works to drive the motor to run and charge the PLC's power supply battery.

[0023] During the operation of the busbar steel coil transport vehicle, when the proximity switch on the collector arm detects that it has lost effective contact with the busbar (that is, it cannot obtain electrical energy from the collector arm), the detection signal of the proximity switch is sent to the PLC. At this time, the PLC controls the second contactor KM2 to disconnect and controls the third contactor KM3 to connect, so that the DC power output by the battery is converted into three-phase AC power through the second AC-DC conversion device, and supplied to the motor fan M1, inverter, and PLC power storage through the sixth circuit breaker QF6 and the fourth circuit breaker QF4 to support the continued operation of the busbar steel coil transport vehicle; when the collector arm is in effective contact with the busbar again (when the collector arm is powered again), the PLC controls the third contactor KM3 to disconnect and the second contactor KM2 to connect to charge the battery.

[0024] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0025] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
