The technical scheme adopted for solving the technical problems is as follows: the utility model provides a ladle operation hanging platform, includes the stand that is fixed in ground, the top of stand is connected with the base through rotation of slewing mechanism, the base is connected with lower arm and connecting rod through a round pin axle rotation, the other end of connecting rod articulates there is the upper arm, the other end of lower arm the other end of upper arm articulates there is the forearm, the lower arm the connecting rod the upper arm with the forearm constitutes parallelogram, the other end of forearm is provided with the lifting hook, the base still is provided with the hydro-cylinder, the upper arm backward extension has the tail section, the piston rod of hydro-cylinder with the tail section articulates.

Further, the base is provided with a chute, and a piston rod of the oil cylinder and a hinge shaft of the tail section are connected to the chute in a sliding manner.

Further, a piston rod of the oil cylinder is hinged with the middle of the tail section, and a counterweight is arranged at the tail of the tail section.

The beneficial effects of the utility model are as follows: the utility model provides a ladle operation hanging platform, its includes the stand that is fixed in ground, the top of stand is connected with the base through rotation of slewing mechanism, the base is connected with lower arm and connecting rod through a round pin axle rotation, the other end of connecting rod articulates there is the upper arm, the other end of lower arm the other end of upper arm articulates there is the forearm, the lower arm the connecting rod the upper arm with the forearm constitutes parallelogram, the other end of forearm is provided with the lifting hook, the base still is provided with the hydro-cylinder, the upper arm backward extension has the tail section, the piston rod of hydro-cylinder with the tail section articulates. The utility model has simple structure, utilizes the parallelogram deformable function to adjust the forward extending height and distance of the front arm, and the lifting hook is directly hinged with the front arm, thus preventing the casting ladle from rotating and swinging in the air and being convenient for workers to operate the casting ladle.

Detailed Description

The utility model will now be described in further detail with reference to the drawings and the specific embodiments, without limiting the scope of the utility model.

As shown in fig. 1 and 2, a ladle operation hanging platform of the present embodiment includes a stand 1 fixed on the ground, a base 2 is rotatably connected to the top of the stand 1 through a rotation mechanism, the base 2 is rotatably connected with a lower arm 3 and a connecting rod 4 through a pin shaft, the other end of the connecting rod 4 is hinged with an upper arm 5, the other end of the lower arm 3 and the other end of the upper arm 5 are hinged with a forearm 6, the lower arm 3, the connecting rod 4, the upper arm 5 and the forearm 6 form a parallelogram, the other end of the forearm 6 is provided with a lifting hook 7, the base 2 is further provided with an oil cylinder 8, the upper arm 5 extends backwards to form a tail section 51, and a piston rod of the oil cylinder 8 is hinged with the tail section 51.

During operation, the front arm 6 is adjusted to extend forward and retract through the oil cylinder 8, and the adjusting range is limited by the structure of the hanging platform and is not quite large, but because the pouring operation is usually fixed at a working position, namely the placement position of a die to be poured is usually fixed, or the placement position of the die to be poured is not changed greatly, the pouring operation can be completely satisfied by adopting the ladle operation hanging platform of the embodiment, and the ladle can be well controlled because no hanging rope is arranged.

The cylinder body of the oil cylinder 8 is fixed on the base 2, the base 2 is provided with a chute 9, and a piston rod of the oil cylinder 8 and a hinge shaft of the tail section 51 are connected to the chute 9 in a sliding manner; thus, when the cylinder 8 expands and contracts, the ladle suspended from the hook 7 moves, and then the ladle is transferred to the pouring position by rotating the base 2. In actual operation, the lifting hook 7 is not used for directly hanging the ladle, but is used for hanging a hanging bracket, and two ends of the ladle are placed on a shackle at the lower end of the hanging bracket through a long rod, so that the ladle can be turned over by the long rod conveniently.

In addition, in order to reduce the stress of the oil cylinder 8 and protect the oil cylinder 8, a piston rod of the oil cylinder 8 is hinged with the middle part of the tail section 51, and a counterweight 10 is arranged at the tail part of the tail section 51. Thus, the balance is maintained at both ends of the upper arm 5 substantially with the hinge point of the parallelogram at the base 2 as a fulcrum.

Finally, it should be noted that the foregoing embodiments are merely for illustrating the technical solution of the present utility model, and the front, rear, left, right, upper, middle, lower, etc. directions adopted for the description of the technical solution are set based on the drawings, not limiting the scope of the present utility model, although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
