When industrial oxygen tanks are transported to the designated location, they need to be unloaded, so an industrial oxygen tank unloading auxiliary device is required.

[0003] Since oxygen tanks are heavy, the conventional way to unload oxygen tanks is for workers to hold the oxygen tanks and push them off the car. When pushing the oxygen tanks down, the oxygen tanks will come into contact with the ground, which will affect the oxygen tank body and reduce the service life of the oxygen tank.

[0015] Preferably, a placement groove is provided in the middle of the platform, and the diameter of the placement groove is larger than the diameter of the oxygen cylinder.

[0016] Working principle: When it is necessary to unload industrial oxygen cylinders, workers place the oxygen cylinders on the top of the first conveyor belt 1 and start the first motor 13. The rotation of the first motor 13 drives the roller 42 to rotate. The rotation of the roller 42 drives the first conveyor belt 1 and the second conveyor belt 2 to rotate. The first conveyor belt 1 rotates to transport the oxygen cylinders. The rotation of the second conveyor belt 2 drives the fixed plate 4 to rotate. The rotation of the fixed plate 4 drives the outer shell 5 to rotate. The rotation of the outer shell 5 drives the telescopic rod 8 to rotate. When the limiting column 10 at the bottom of the telescopic rod 8 contacts the T-shaped plate 12, the limiting column 10 will slide and drive 8 to slide. The sliding of the telescopic rod 8 drives the first splint 9 to slide to fix the oxygen cylinder, so that the oxygen can be transported during the transportation of the oxygen cylinder. The gas cylinder can always remain stable. When the oxygen cylinder is transported to the end of the first conveyor belt 1, the limit column 10 will reduce the contact with the T-shaped plate 12, so that the first spring 7 pushes the blocking block 6 to slide through the elastic reset, thereby driving the telescopic rod 8 to slide, so that the fixing effect of the first splint 9 on the oxygen cylinder is reduced until it disappears completely. At this time, the oxygen cylinder will be transported to the upper part of the third conveyor belt 16 for secondary transportation. In the process of secondary transportation of the oxygen cylinder, the second motor 24 will rotate to drive the first rotating shaft 15 to rotate, so that the third conveyor belt 16 rotates to transport the oxygen cylinder. While the first rotating shaft 15 drives the third conveyor belt 16 to rotate, through the combination of the active pulley 17, the first driven pulley 18 and the belt 19, The second rotating shaft 20 rotates to drive the fourth conveyor belt 22 to rotate, and the rotation of the fourth conveyor belt 22 drives the stopper 23 on the upper side of the fourth conveyor belt 22 to support the oxygen cylinder to prevent the oxygen cylinder from tipping over during the secondary conveying process. When the oxygen cylinder is transported to the end of the third conveyor belt 16 for the second time, the oxygen cylinder will slide into the upper part of the platform 34 and fall into the placement groove 35. At this time, the third motor 33 will be started. When the oxygen cylinder falls into the placement groove 35, the bottom of the oxygen cylinder will contact the placement plate 40, and the placement plate 40 will be lowered by gravity. The placement plate 40 is lowered and drives the connecting rod 39 to rotate. The rotation of the connecting rod 39 drives the H-shaped slider 36 to slide. The sliding of the H-shaped slider 36 drives the second clamping plate 37 to support the oxygen cylinder. The third motor 33 is fixed and squeezes the second spring 38, and the third rotating shaft 28 is driven to rotate by the rotation of the third rotating shaft 28. The rotation of the third rotating shaft 28 drives the first bevel gear 32 to rotate. The rotation of the first bevel gear 32 drives the second bevel gear 31 to rotate. The rotation of the second bevel gear 31 drives the reciprocating screw rod 29 to rotate. The rotation of the reciprocating screw rod 29 drives the fixed sleeve 30 to slide back and forth. The reciprocating sliding of the fixed sleeve 30 drives the platform 34 to slide back and forth. In the process of the platform 34 sliding, the placement plate 40 will first contact the ground, causing the placement plate 40 to slide upward, thereby causing the connecting rod 39 to rotate and drive the H-shaped slider 36 to slide, and the second spring 38 is reset to make the second clamping plate 37 completely separate from the fixed state between it and the oxygen cylinder.This makes it easier for staff to take the oxygen cylinder.

[0017] The present invention provides an auxiliary device for unloading industrial oxygen tanks. It has the following beneficial effects:

[0018] 1. The present invention cooperates with each other among the first conveyor belt, the positioning assembly, the fixing assembly, the baffle, the T-shaped block, the first motor, the roller, and the frame, so that the industrial oxygen tank unloading auxiliary device can continuously transport the oxygen tanks and simultaneously realize fast and convenient positioning of the oxygen tanks, thereby reducing labor input.

[0019] 2. The present invention achieves secondary transport of oxygen tanks and unloads the oxygen tanks from a high place by cooperating with each other among the second motor, the support column, the auxiliary assembly, the transmission assembly, the drive assembly, the clamping assembly, the platform, the placement slot slide rod, and the fixing sleeve, and fixes the oxygen tanks during the unloading process.
