Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, in particular to a track power supply device for a mobile ingot mold train set. Background Art

[0002] The electric furnace smelting process is continuous, with tapping occurring every 2 to 2 hours and 40 minutes. Each tapping cycle involves pouring, demoulding, and storage. The ladle is transported to the ladle turner via a pouring ladle car. The ladle turner then tilts the ladle and pours the molten iron into the mobile ingot mold via a chute. The mobile ingot mold car then moves to complete the pouring process. After pouring, the mobile ingot mold car moves to the demoulding position for demoulding.

[0003] The power supply required for the movement of the mobile ingot mold car group is generally obtained through the track running wheels in the existing technology. In order to achieve safe voltage power supply, the power input line is 380V, which is converted into 36V through a step-down transformer and connected to the two running tracks through cables. The moving wheels serve as electrical collectors to obtain the 36V voltage to the tractor. The tractor is equipped with a step-up transformer to increase the 36V to 380V, and the vehicle is driven by the motor.

[0004] Because two-phase power is drawn from the wheels on the running rails, reliable insulation is essential. During manufacturing, insulating sleeves are installed on the bearings to insulate both wheels. However, during use, as the mobile ingot mold car pours molten iron, even the slightest leak of hot iron can damage the wheel insulation, leading to frequent short-circuit tripping and failures, which in turn render the mobile ingot mold car inoperable. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a track power supply device for a mobile ingot mold train set, so as to avoid the problem of frequent track short circuit failures caused by high temperature burning of molten iron.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a track power supply device for a mobile ingot mold vehicle group, comprising a power supply module, a power supply module, and a drive module; the power supply module is connected to the power supply module, and the drive module is connected to the power supply module; the power supply module is used to provide power to the track in the power supply module; the power supply module is used to provide power from the power supply module to the drive module; the drive module is used to control the movement of the mobile ingot mold vehicle group;

[0007] The power taking module includes a power taking track and a power taking slider. The power taking slider is arranged on the movable ingot mold vehicle group, and the power taking slider is in contact with the power taking track.

[0008] The utility model is further configured as follows: the power-taking track is arranged below the movable ingot mold vehicle group, and the power-taking slider is arranged at the bottom of the movable ingot mold vehicle group.

[0009] The utility model is further configured as follows: the power supply module includes a power supply and a transformer, and the power supply is connected to the transformer and then connected to the power rail.

[0010] The utility model is further configured as follows: the driving module includes a step-up transformer and an AC control system; the power-taking slider is connected to the step-up transformer and then to the AC control system.

[0011] The utility model is further configured as follows: the mobile ingot mold car group track power supply device also includes a walking track, and there are two walking tracks, which are respectively arranged below the left and right sides of the mobile ingot mold car group.

[0012] The utility model is further configured as follows: a traveling wheel is further provided at the bottom of the movable ingot mold vehicle group, and the position of the traveling wheel is adapted to the position of the traveling track; the traveling wheel is provided on the traveling track and moves along the traveling track.

[0013] The utility model is further configured as follows: a steel sleeve is additionally installed on the bearing of the traveling wheel.

[0014] The utility model is further configured as follows: two power-taking tracks are provided, and the power-taking tracks are provided on the inner sides of the two walking tracks.

[0015] This application adopts the method of laying two new power rails in the middle of the walking track to independently draw power from the train set. The 380V power supply voltage in the power supply module is reduced to 36V by a transformer and then connected to the two power rails respectively. The power is drawn from the two power rails through an eight-shaped conductive slider and introduced into the drive module on the mobile ingot mold car. At this time, the power is then boosted from the two-phase AC 36V to three-phase AC 380V through a step-up transformer and supplied to the drive module. The AC control system in the drive module controls the start, stop, forward and backward of the mobile ingot mold car set.

[0016] The beneficial effects of the above technical solution of the utility model are as follows:

[0017] By adding a power rail, this utility model solves the problem of conventional mobile ingot mold trains using wheels as power supply, which requires wheel insulation. Without the need for wheel insulation, the wheel bearings do not need insulating sleeves; steel sleeves can meet the requirements. Steel sleeves are far more resistant to pressure and high temperatures than insulating sleeves, preventing wheel insulation damage caused by high temperatures, which could lead to power short circuits, and significantly reducing the failure rate.
