[0032] The side of the furnace door welding body 1 is connected to the counterweight seat 2, and the longitudinal moving mechanism 3 is connected to the bottom of the counterweight seat 2; the furnace door track 5 is arranged outside the furnace door of the horizontal vacuum furnace; the direction of the furnace door track 5 is perpendicular to the axis of the horizontal vacuum furnace; the transverse moving mechanism 4 is slidably connected to the furnace door track 5; the upper surface of the transverse moving mechanism 4 is provided with a longitudinal track, and the longitudinal moving mechanism 3 is slidably connected to the longitudinal track, and the direction of the longitudinal track is parallel to the axis of the horizontal vacuum furnace. The longitudinal moving mechanism 3 includes a frame, and the two ends of the frame are respectively connected to the longitudinal moving reduction motor 7; the longitudinal moving reduction motor 7 is connected to the active walking wheel 8 of the longitudinal moving mechanism through the longitudinal moving mechanism transmission shaft 9 and the key. The frame is connected to a guide device 10; the guide device 10 is provided with a guide wheel 101, and the transverse moving mechanism 4 is provided with a guide groove 401, and the guide wheel 101 is slidably connected to the guide groove 401. The frame is also provided with an anti-tipping device 11, which includes a connecting seat 111 and a connecting bolt 112; the lateral moving mechanism 4 is provided with an anti-tipping slot 402, which can be anti-tipping by being engaged in the anti-tipping slot 402 through the connecting bolt 112 after being moved into position.

[0033] An anti-tilt device 11 is provided on both sides of the guide device 10 .

[0034] One end of the transverse moving mechanism 4 is connected to the transverse moving mechanism active walking wheel 15, and the other end is connected to the transverse moving mechanism driven walking wheel 17; the transverse moving reduction motor 12 is key-connected to the transverse moving mechanism active walking wheel 15 through the connecting sleeve 13, the universal coupling 14, and the transverse moving mechanism transmission shaft 16.

[0035] The lateral moving mechanism 4 is connected to the Silver Star guard plate drag chain 6, and a power supply cable is passed through the Silver Star guard plate drag chain 6 to realize mobile power supply.

[0036] Specifically, the furnace door welding body 1 and the longitudinal moving mechanism 3 are connected through the counterweight seat 2, and the center of gravity is matched by welding the steel plate on the side of the furnace door welding body 1, so that the center of gravity of the upper overall moving structure of the transverse moving mechanism 4 falls at the geometric center, achieving smooth and reliable movement.

[0037] The longitudinal moving mechanism 3 is driven by two sets of longitudinal moving reduction motors 7, which are connected to the longitudinal moving mechanism active walking wheels 8 via the longitudinal moving mechanism transmission shaft 9 and a key. The two sets of driving devices are controlled in a closed loop to achieve synchronous operation.

[0038] The longitudinal moving mechanism 3 is provided with a guide device 10 and an anti-tilt device 11 during the movement process. The guide wheel of the guide device 10 and the guide track are line contact guides to prevent surface contact from over-positioning and getting stuck.

The center of gravity is matched by welding the steel plate on the side of the furnace door welding body 1, so that the center of gravity of the upper overall moving structure of the transverse moving mechanism 4 falls at the geometric center. The longitudinal movement of the furnace door is driven by the longitudinal moving mechanism 3, and then the transverse movement of the entire furnace door assembly is driven by the transverse moving mechanism 4, so as to realize the opening and closing of the furnace door.

[0044] The utility model has the advantages of simple structure, safety and reliability, and makes corresponding improvements and solutions to the problems of sagging, poor sealing performance, low safety, time-consuming and labor-intensive hinged furnace doors of large horizontal vacuum furnaces, and large footprint of hinged doors.
