Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1-4, a casting box-turning hanger comprises a beam 1 and sand boxes 2, wherein the spreader 3 is suspended at both ends of the beam 1, the spreader 3 comprises pulleys 31 and chains 32 surrounding the pulleys 31, the chains 32 are of a closed loop structure on the pulleys 31, the sand boxes 2 comprise an upper mold 21 and a lower mold 22 matched with the upper mold 21, at least two handles 23 are respectively arranged at both sides of the upper mold 21 and both sides of the lower mold 22, and chain wheels 24 which can be detached and matched with the chains 32 are arranged on the handles 23, the spreader is arranged so as to be capable of lifting a larger sand box through a machine, so that labor is saved, and the cooperation of the chains and the pulleys enables the sand boxes to be lifted through the chains and directly pull the chains, so that the sand boxes can be turned, the turning of the sand boxes is more labor-saving and stable, and the arrangement of the chain wheels can avoid the slippage on the handles from the chains to affect the turning of the sand boxes, guarantee the drive reliability of chain to the sand box upset, and avoid the chain slippage outwards and lead to the sand box to drop, reduced the danger of sand box upset.

The pulley 31 is fixed on the pulley support 33 through the pulley shaft 311, the pulley shaft 311 penetrates through the pulley support 33, two ends of the pulley shaft 311 are respectively limited and fixed through bolts, the side wall of the pulley 31 is provided with an annular groove 312 for accommodating the chain 32, the pulley is arranged through the pulley shaft, so that the chain can realize loop type movement on the pulley, the chain can be continuously pulled to overturn the sand box, the limitation of the turnover angle of the sand box is realized, the annular groove is arranged, the chain can be limited laterally, and the phenomenon that the chain slips from the lateral direction to affect the turnover work of the sand box is avoided; the top of pulley bracket 33 is equipped with the solid fixed ring 331 that can hang on crossbeam 1, be equipped with at least one on the top surface of crossbeam 1 and be used for on solid fixed ring 331 with the spacing group 11 in the position both sides of crossbeam 1 butt, spacing group 11 includes two spacing archs 111 of locating solid fixed ring 331 both sides respectively, the setting of the above-mentioned limit group, so that carry out spacingly to the solid fixed ring that hangs on the crossbeam, avoid the easy skew of hoist and influence the normal upset of sand box, and avoid the hoist to break away from the crossbeam and cause danger.

Use the driving a vehicle to lift by crane the hoist, guarantee bilateral symmetry during the use, weld safe muscle after the pulley support is hung to the crossbeam, place the crossbeam and drop pulley system when inclined to one side, hang the sprocket on the sand box case handle on the chain during the case is turned over, once hard after lifting a take the altitude, make the sand box rotate, reach the case turning over purpose, because the sand box case forms triangle-shaped with the sprocket, stability when having strengthened the sand box upset, and when the sand box overturned arbitrary angle, have two at least sprockets and keep being connected with the chain on the sand box all the time, thereby stability when guaranteeing the sand box upset.

As shown in fig. 3-4, the sprocket 24 is provided with a through hole 241 for the container handle 23 to pass through, the inner wall of the through hole 241 is provided with at least one limiting portion 242 protruding towards the inner side, the sidewall of the container handle 23 is provided with a slot 231 for the limiting portion 242 to insert and move, and the arrangement of the limiting portion and the slot enables the sprocket to be limited on the container handle, prevents the sprocket from rotating around the axis on the container handle, ensures that the chain can be firmly clamped on the sprocket, enhances the controllability of the chain on the turnover of the sand box, and facilitates the disassembly of the chain due to the arrangement of the slot; the outer end of sprocket 24 is equipped with latch segment 25 near the sprocket 24 terminal surface, the outer end that corresponds to sprocket 24 on the lateral wall of case handle 23 is equipped with external screw thread 232, threaded connection between latch segment 25 and the case handle 23, the threaded connection of above-mentioned latch segment and case handle, it is spacing to make the latch segment carry out the terminal surface with the fluting cooperation to the chain, when avoiding the chain to be connected with the sprocket, the removal of axis direction takes place for the sprocket, the stability of sprocket when guaranteeing the chain removal, stability when improving the sand box upset, latch segment accessible screw thread breaks away from the case handle at any time simultaneously, thereby made things convenient for the dismantlement and the installation of sprocket, so that the reuse of sprocket.

Before winding the chain on the case handle, place the sprocket on the case handle along the fluting earlier, until unable removal, the latch segment along the screw thread twist towards the sprocket, until screwing up to accomplish the fixed to the sprocket, if will dismantle the sprocket, then reverse twist move the latch segment can, then hang the sprocket on the chain, manpower pulling chain, thereby the upset to the box is realized.
