Description

Technical Field

[0001] The utility model relates to the technical field of pouring equipment, in particular to a pouring bag. Background Art

[0002] The molten iron ladle is widely used in casting operations in the foundry industry workshop. After receiving the molten iron in front of the furnace, it is transported to the casting mold by a crane for casting. The molten iron casting ladle is driven by a primary worm and a secondary worm through a sprocket and a chain (pulley, belt). After deceleration, the barrel body is slowly tilted to evenly pour out the molten metal in the barrel to complete the casting process. The deceleration mechanism consists of a set of sprockets (pulleys) and a two-stage worm drive. The worm is made of high-quality steel and is quenched and tempered and surface quenched. The worm wheel is made of high-quality aluminum bronze, which has high strength and stable transmission. It also has reliable self-locking performance and is safe and reliable to use.

[0003] Due to the large size of the pouring ladle and its heavy weight when filled with molten iron, the chain and the corresponding gears and worm gears may break during long-term use or in the event of a collision. Once the gears or worm gears break, the tilting pouring ladle may easily shake violently, and even all the molten iron inside may be dumped out, posing a major safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] Example: Please refer to Figure 1 , a pouring ladle, comprising a pouring body 14 rotatably connected to a mobile frame 5 through a rotating shaft 11, a driving mechanism for driving the rotating shaft 11 to rotate and a first cross bar 17 fixed to the pouring body 14, the first cross bar 17 is rotatably connected to the first rotating member 4 at both ends, the first cross bar 17 is provided with a vertical rod 18, the vertical rod 18 is provided with a second cross bar, the second cross bar is rotatably connected to the second rotating member 12, the first rotating member 4 and the second rotating member 12 are connected to an elastic contraction mechanism 2 through a steel wire rope 3, and the first rotating member 4 is connected to the elastic contraction mechanism 2 located at the bottom of the mobile frame 5, the second rotating member 12 is connected to the elastic contraction mechanism 2 located at the top of the mobile frame 5, the elastic contraction mechanism 2 is a retractor in a car seat belt, wherein the retractor is a retractor for a car seat belt, since the driving mechanism is slow in the process of driving the rotating shaft 11 to rotate (facilitating the pouring of molten iron), therefore, in this process, the coil spring inside the retractor plays the function of rewinding the steel wire rope 3 to prevent the steel wire rope 3 from loosening; Among them, the rotation connection method can adopt the form of clearance fit; when the gear, chain or worm wheel breaks, the casting body 14 will tilt in a short time. When tilting forward, the upper wire rope 3 will be stretched faster, so that the buckle piece inside the retractor is buckled with the ratchet under the action of centrifugal force, thereby preventing the wire rope 3 from being pulled out, and then preventing the casting body 14 from tilting forward. When the casting body 14 tilts backward, the retractor below will lock the wire rope 3, thereby preventing the casting body 14 from tilting, thereby greatly reducing the safety hazard; there are four elastic contraction mechanisms 2, two of which are fixed to the top and bottom of the moving frame 5, respectively, and the elastic contraction mechanisms 2 of the same height are arranged symmetrically, the bottom of the moving frame 5 is fixedly connected to an L-shaped plate 9, and the elastic contraction mechanism 2 is fixedly connected to the L-shaped plate 9, and the top of the moving frame 5 is provided with a third cross bar 8, and the third cross bar 8 is provided with a fixing ear 1, and the elastic contraction mechanism 2 is fixedly connected to the third cross bar 8, which ensures uniform force on the casting body 14.

[0021] In this embodiment, a connecting rod 15 is provided on the first cross bar 17, and one end of the connecting rod 15 is connected to the casting body 14, thereby improving the stability of the connection between the cross bar and the casting body 14; and the ends of the first cross bar 17 and the second cross bar are threadedly connected with a blocking cover, which is convenient for installation and can prevent the first rotating member 4 and the second rotating member 12 from slipping out; a filter plate 16 is fixedly connected to the inside of the casting body 14 near the pouring port, which is used to filter iron slag and improve the quality of molten iron; and the lower part of the movable frame 5 is provided with a rotating table 13 rotatably connected to the rotating shaft 11, one of the rotating shafts 11 passes through the rotating table 13 and is fixedly connected to the output end of the reduction box 10 fixedly connected to the rotating table 13, and the input end of the reduction box 10 is fixedly connected to the driving hand wheel 6, wherein the reduction box 10 adopts the existing reduction box 10, which will not be described in detail here; and a rotating handle 7 is fixedly connected to the driving hand wheel 6, so that the staff is separated from the casting body 14 by a certain position to ensure the personal safety of the staff.

[0022] How it works

[0023] When the gear, chain or worm wheel breaks, the casting body 14 will tilt in a short time. When tilting forward, the upper wire rope 3 will be stretched faster, so that the snap piece inside the upper reel will be snapped with the ratchet under the action of centrifugal force, thereby preventing the wire rope 3 from being pulled out, and then preventing the casting body 14 from tilting forward. When the casting body 14 tilts backward, the reel below will lock the wire rope 3, thereby preventing the casting body 14 from tilting backward, thereby greatly reducing safety hazards.
