Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing processing, in particular to a novel transfer mechanism. Background Art

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metal, alloy or other materials for aesthetic purposes and rust prevention. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will form on the surface of zinc. The standard electrode potential of zinc is -0.76V. For steel substrates, zinc coating is an anodic coating. It is mainly used to prevent corrosion of steel. The quality of its protective performance is closely related to the thickness of the coating. After passivation, dyeing or coating with a light protectant, the protective and decorative properties of the zinc coating can be significantly improved.

[0003] At present, in the galvanizing industry on the market, according to the galvanizing process requirements, the galvanized workpieces are transported from the "pre-treatment area" to the "galvanizing area" by a crane for galvanizing operations. In actual production, some sites are limited in length or under other circumstances, and the "pre-treatment area" and the "galvanizing area" will not be built in the same span, such as an L-shaped operating area (that is, the "pre-treatment area" and the "galvanizing area" are arranged in L shape). At this time, the crane transporting the parts will not directly turn the L curve. At this time, two tracks need to be laid, and transfer is difficult at the junction of the two tracks.

[0023] A novel transfer mechanism comprises a frame 1, a transmission assembly 2 is arranged outside the frame 1, a hanging rail assembly 3 is arranged at the bottom end of the frame 1, and an anti-derailment assembly 4 is arranged on the outer wall of the frame 1;

[0024] The hanging rail assembly 3 includes a rotating cylinder 301 and a top flange 302 fixedly connected to the top of the rotating cylinder 301. The rotating cylinder 301 is rotatably connected relative to the frame body 1. A plurality of first end flanges 303 are welded to the outer wall of the rotating cylinder 301. The first end flange 303 is connected to the rotating cylinder side body 304 by bolts. A first bottom flange 305 is fixedly connected to the bottom end of the rotating cylinder 301. The bottom end of the first bottom flange 305 is connected to the hanging rail bracket 306 by bolts, and the top of the hanging rail bracket 306 is also connected to the bottom end of the rotating cylinder side body 304 by bolts.

[0025] In a preferred embodiment, the transmission assembly 2 includes an outer ring gear 201 and a pinion gear 203 meshingly connected to one side of the outer ring gear 201. The bottom end of the outer ring gear 201 is connected to the top flange 302 by bolts. A reduction motor 202 is fixedly connected to the top of the frame body 1. The output shaft of the reduction motor 202 is fixedly connected to the pinion gear 203. When the rotating cylinder 301 moves, the rotating cylinder 301 can drive the first end flange 303 to move, so that the first end flange 303 can drive the rotating cylinder side body 304 to move in a circular motion.

[0026] In a preferred embodiment, the anti-derail assembly 4 includes an L-shaped hanger 401 and a second end flange 402 fixedly connected to one end of the L-shaped hanger 401, the second end flange 402 is connected to the outer wall of the frame body 1 by bolts, the first end flange 303 is connected to the side of the rotating cylinder 301 by 4 bolts, and the first bottom flange 305 is connected to the hanging rail bracket 306 to improve the stability of the hanging rail bracket 306.

[0027] In a preferred embodiment, the L-shaped hanger 401 is fixedly connected to a second bottom flange 403 at one end away from the second end flange 402. The second bottom flange 403 is connected to a limit stop plate 404 by bolts. The L-shaped hanger 401 and the limit stop form a cantilever beam structure, and the inner arc surface of the limit stop is used to limit the hoist from derailing.

[0028] In a preferred embodiment, the cross-sectional shape of the limit baffle 404 is an arc shape, the outer wall of the first end flange 303 is connected to the turntable frame 5 by bolts, and the turntable frame 5 and the rotating cylinder side body 304 are distributed on the outer wall of the rotating cylinder 301 in a cross shape. When the rotating cylinder 301 rotates, the rotating cylinder 301 will drive the turntable frame 5 to move, so that the turntable frame 5 outside the rotating cylinder 301 moves together with the hanging rail bracket 306.

[0029] In a preferred embodiment, the turntable frame 5 is fixedly connected to a third bottom flange 6 at one end away from the first end flange 303, and the bottom end of the third bottom flange 6 is connected to a turntable body 7 by bolts, and the cross-sectional shape of the turntable body 7 is semicircular. When the turntable frame 5 moves, the turntable frame 5 will drive the turntable body 7 to move, so that the turntable body 7 can move with the hanging rail bracket 306.

[0030] Working principle of the utility model: the new indexing machine is installed on the center lines of the A and B rails that intersect each other in the galvanizing production line. When the new indexing machine is working, the small gear 203 on the reduction motor 202 in the transmission component 2 rotates to drive the outer teeth of the outer ring gear 201 to rotate. The outer ring gear 201 is connected to the hanging rail device. The outer ring gear drives the hanging rail device to rotate to the required working angle. At the same time, the outer ring gear 201 will drive the rotating cylinder 301 to move, so that the rotating cylinder 301 rotates relative to the frame 1. At the same time, the rotating cylinder 301 can drive the rotating cylinder side body 304 and the turntable frame 5 to reciprocate in a circular motion through the first end flange 303 of the outer wall. At this time, the rotating cylinder 301 will drive the hanging rail bracket 306 to rotate through the first bottom flange 305 and the rotating cylinder side body 304, so that the transmission component 2 can rotate and drive The hanging rail assembly 3 rotates, and when the hanging rail assembly 3 rotates from the A track position to coincide with the B track position, it stops rotating. The driving hoist completes the transfer and performs operations on the track. During the rotation of the transmission assembly 2, in order to prevent the driving hoist from leaving the hanging rail assembly 3 due to misoperation, an anti-derail assembly 4 is added to limit its accidents, so that the L-shaped hanger 401 and the limit baffle 404 in the anti-derail assembly 4 can limit the driving hoist. At the same time, in order to prevent the polluted gas from overflowing from below the hanging rail in the closed room of the operating area, a turntable frame 5 and a turntable body 7 that rotate with the hanging rail are added. The turntable frame 5 and the turntable body 7 are driven to rotate with the hanging rail through the rotation of the rotating cylinder 301, so as to ensure that the rotating driving hoist is not affected by the turntable frame 5 and the turntable body 7. This indexing machine meets the requirements of the intercommunication operation of the driving hoist on two cross tracks without stopping.
