Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically a slag ladle tilting device. Background Technology

[0002] After smelting in the converter, the slag ladle in the metallurgical industry needs to be transferred. The slag ladle is lifted by an overhead crane and then transferred to the slag dumping station for dumping. During the dumping process, the overhead crane needs to be manually operated to hook and tilt the slag ladle. Since the entire process relies on manual operation of the overhead crane to complete the hooking, lifting and tilting actions, the hooking work needs to be completed accurately by manpower before each slag ladle transfer or tilting. The high-temperature working environment is filled with dust and various harmful gases, which not only results in high labor intensity and low work efficiency for workers, but also poses safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a slag bag tipping device that uses a hydraulic cylinder to tip the slag bag, thereby solving the problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A slag bag tipping device includes a tipping support and a tipping frame. The tipping frame includes a base, and two slag bag support frames with frame structures perpendicular to the base are symmetrically installed on the left and right sides of the upper surface of the base. The slag bag support frame includes a bottom edge, a rear side edge perpendicular to the bottom edge, and a front side edge, with the front side edge located at the front section of the bottom edge. A tipping cylinder is installed between the front side edge and the tipping support. A slag bag trunnion seat fixing plate is installed between the inner walls of the front and rear side edges. A U-shaped slag bag trunnion is formed at the upper center of the slag bag trunnion seat fixing plate. The positioning hole is hinged to the top of the front side and the lower part of the tail end of the locking pressure plate. The upper part of the tail end of the locking pressure plate is hinged to the rear end of the locking pressure plate connecting rod. The front end of the locking pressure plate connecting rod is hinged to the top of the piston rod of the locking cylinder and the front end of the tilting frame connecting rod. The cylinder seat of the locking cylinder is installed at the front end of the bottom side. The rear end of the tilting frame connecting rod is hinged to the side wall of the front side. The rear end of the locking pressure plate is equipped with a pin limiting hole. The upper part of the outer wall of the rear side is equipped with a pin cylinder corresponding to the pin limiting hole. The rear side is hinged to the tilting support.

[0005] Preferably, the tilting support includes two symmetrically arranged L-shaped support side arms. The bottom of the support side arms is connected to the front crossbeam and the rear crossbeam of the support, respectively. The front end of the support side arm is connected to the cylinder seat of the tilting cylinder. The top of the piston rod of the tilting cylinder is hinged to the cylinder connecting seat fixed on the upper part of the outer side wall of the front side.

[0006] Preferably, slag bag positioning baffles are installed on the front and rear sides of the upper surface of the base, and slag bag positioning baffles are provided with slag bag front and rear support leg positioning grooves in the middle. Stepped support plates adapted to the shape of the slag bag front and rear support legs are installed between the hole walls of the slag bag front and rear support leg positioning grooves.

[0007] Preferably, the two slag bag trunnion seat fixing plates are U-shaped frame structures that are adapted to the shape of the slag bag trunnion seat; the lower part of the inner wall of the slag bag trunnion seat fixing plate is respectively installed with the base and the left and right support leg limiting grooves of the slag bag, the left and right support leg limiting grooves of the slag bag include two side baffles, and there is a stepped support plate between the two side baffles that is adapted to the shape of the left and right support legs of the slag bag.

[0008] Preferably, the base has a vent hole at its center, and slag pads arranged in a circular pattern are provided on the outer side of the vent hole.

[0009] Preferably, the rear end of the locking plate is a hook, and the curvature of the lower side of the hook is adapted to the shape of the trunnion of the slag bag.

[0010] The working process of this utility model is as follows: The operator controls the piston rod of the locking cylinder to retract, and the locking cylinder, through the locking pressure plate connecting rod, rotates the hook of the locking pressure plate clockwise, fully opening the locking pressure plate. The tilting cylinder is in its initial position, and the base is in a horizontal state. The operator controls the crane to lift the slag ladle filled with molten metal to the tilting frame. The slag ladle gradually descends, and the position of the slag ladle is adjusted. For casting slag ladles, its trunnion seat abuts against the slag ladle trunnion seat fixing plate, and the casting slag ladle is securely placed in the tilting frame. For welding slag ladles, the legs on the lower part of its side wall fall into the left and right support leg limiting grooves and the front and rear support leg positioning grooves of the slag ladle, and the welding slag ladle is securely placed in the tilting frame. Since the trunnion height of the casting slag ladle is lower than that of the welding slag ladle, the bottom of the casting slag ladle is placed on the slag ladle pad to ensure the trunnion height. After the crane hook detaches from the slag bag, the operator controls the piston rod of the locking cylinder to extend. The locking cylinder, through the locking plate connecting rod, pushes the locking plate to rotate counterclockwise. The hook at the rear end of the locking plate fastens onto the trunnion of the slag bag. Then, the operator controls the piston rod of the pin cylinder to extend and insert into the pin hole on the outer wall of the locking plate, limiting the locking plate. The operator controls the piston rod of the tilting cylinder to extend. The tilting cylinder pushes the tilting frame and the slag bag to rotate, tilting the slag bag at an angle greater than 90°, approximately 110°, allowing the molten metal inside the slag bag to flow out. After all the molten metal has flowed out, the operator controls the piston rod of the tilting cylinder to retract, returning the slag bag to its initial position. The operator then controls the piston rods of the pin cylinder and the locking cylinder to retract, opening the locking plate again, allowing the slag bag to be lifted out of the tilting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a hinged tilting frame and a tilting support. The slag bag can be securely placed in the tilting frame by locking the pressure plate. The tilting action is achieved by pushing the slag bag with the tilting cylinder. The operator can remotely control it through the hydraulic system, away from the high temperature and pollution environment, effectively reducing the labor intensity of the personnel and significantly improving the work efficiency. This invention uses a pin-type hydraulic cylinder to limit the locking plate, thus improving the reliability of the equipment. This utility model provides slag ladle trunnion seat fixing plates on the left and right sides of the tilting frame, which can reliably support the trunnion seat of the casting slag ladle. The tilting frame is provided with left and right support leg limiting grooves and front and rear support leg positioning grooves for the slag ladle, which can reliably position the support legs of the welding slag ladle and meet the tilting operation of different types of slag ladles. This utility model provides a slag bag pad in the center of the base, which can buffer the impact on the tilting frame base when the slag bag descends; This utility model has an exhaust hole in the center of the base to facilitate the detachment of the slag bag from the tilting frame when it is lifted.
