The third cover 22 is connected to the inner cavity of the moving beam 9.

[0027] The moving beam 9 has two water-cooling channels 23 located at the top and bottom respectively on its front side, and the drive shaft 19.1 and the lead screw 13.2 are respectively located between the two water-cooling channels 23 at the top and bottom.

[0028] The steel belt traction mechanism also includes a cooling system, which includes a pipeline drag chain 24 and a fan 25 installed on one side of the steel belt discharge conveyor platform 1. The pipeline drag chain 24 is equipped with air pipes and water pipes. The air inlet of the fan 25 is connected to an air inlet pipe 26 located outdoors. The air outlet of the fan 25 is connected to the air inlet in the pipeline drag chain 24 through a pipe. The air outlet of the air pipeline drag chain 24 is connected to the rear end of the track platform 2, the lower outer wall of one side of the hollow column 6.1, and the outer wall of the third cover 22 through pipes.

[0029] The pipeline drag chain 24 is equipped with two water pipes 27. The fixed end of one water pipe 27 is connected to the inlet pipe 28, and the fixed end of the other water pipe 27 is connected to the return pipe 29. The ends of the two water pipes 27 away from the fixed ends are respectively connected to one end of a water cooling channel 23. The other ends of the two water cooling channels 23 are connected by a connecting pipe 33.

[0030] The pipeline drag chain 24 is also equipped with a high-temperature resistant hose 30, through which a cable 31 is threaded. The walking drive mechanism 5, the lifting drive mechanism 8, the lateral displacement drive mechanism 13, and the rotation drive mechanism 19 are respectively connected to the power supply and control system cables through the cable 31 threaded through the high-temperature resistant hose 30.

[0031] The working process of this utility model: 1) In the initial state, the lateral displacement drive mechanism 13 on the back of the first slide plate 11 and the second slide plate 12 drives the corresponding lead screw 13.2 to rotate, so that the distance between the active clamping roller 16 and the driven clamping roller 18 of the steel strip is greater than the thickness of the steel strip.

[0032] 2) The lifting drive mechanism 8, in conjunction with the lateral displacement drive mechanism 13, moves to the front side of the steel strip and drives the active steel strip clamping roller 16 and the driven steel strip clamping roller 18 to be positioned downwards on both sides of the steel strip thickness direction. Then, the lateral displacement drive mechanism 13 on the back of the first slide plate 11 and the second slide plate 12 drives the active steel strip clamping roller 16 and the driven steel strip clamping roller 18 to clamp the steel strip (at this time, the clamping position may be close to the end of the front end of the steel strip or far away from the end of the front end of the steel strip).

[0033] 3) The roller rotation drive motor 19.2 drives the active steel strip roller 16 to rotate, which in turn drives the steel strip to be conveyed backward. After the steel strip extends forward 30-50cm relative to the active steel strip roller 16 and the driven steel strip roller 18, the roller rotation drive motor 19.2 stops rotating.

[0034] 4) The steel strip discharge conveyor platform 1 drives the steel strip forward, and at the same time the walking drive motor 5.4 drives the gear 5.5 and rack 5.3 to mesh and drive the steel strip between the active clamping roller 16 and the driven clamping roller 18 to move forward synchronously.

[0035] 5) When the distance between the steel belt and the output roller 32 reaches 30-50cm, the steel belt discharge conveyor platform 1 and the walking drive mechanism 5 stop working.

[0036] 6) The clamping roller rotation drive motor 19.2 drives the steel strip active clamping roller 16 to rotate, driving the steel strip forward and outputting it through the gap between the output rollers 32.

[0037] During operation, the fan 25 supplies outdoor cold air to the track platform 2, gantry 6, and third housing 22, while cooling water is supplied to the water-cooling channel 23 via the water inlet pipe 28. The cold air in the track platform 2 cools the track platform 2 itself and the longitudinal track 3, sliding base 5.1, rack 5.3, gear 5.5, etc., above it. The cold air in the gantry 6 cools the lifting drive motor 8.3 in the first housing, the worm gear screw jack 8.1 and rotating shaft 8.2 in the gantry 6, and the travel drive motor 5.4 in the second housing 21. The third housing 22... The cold air cools the transverse drive motor 13.3 and the clamping roller rotation drive motor 19.2, and is simultaneously input into the moving beam 9 and output from the third air outlet 9.1 to cool and reduce the temperature of various components mounted on the moving beam 9, such as the drive shaft 19.1, bevel gear 19.3, first slide plate 11, second slide plate 12, transverse displacement drive mechanism 13 (excluding transverse drive motor 13.3), drive shaft 15, driven shaft 17, steel belt drive clamping roller 16, and steel belt driven clamping roller 18. The water cooling channel 23 can further improve the cooling effect and reduce the temperature of the cold air output from the third air outlet 9.1.

[0038] During a month of continuous trial operation, the temperature of the traction mechanism was maintained within the allowable operating temperature range, and no overheating shutdown occurred.
