Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage screening of Chinese medicinal pieces, in particular to a lifting device for a pressure container. Background Art

[0002] When manufacturing large pressure vessels, two large-diameter container cylinders need to be welded to ensure the capacity of the container. When welding the large-diameter container cylinder, a lifting rope is usually passed through the inside of the cylinder manually, and then both ends of the lifting rope are hung on the hook, and then the container cylinder is moved by the truss crane to the top of the welding equipment;

[0003] The existing lifting equipment for the container cylinder generally only uses the lifting rope as the auxiliary lifting equipment of the container cylinder. The lifting rope will inevitably be worn by the inner edge of the container cylinder after a long time of use, and the service life is short. In addition, when lifting, the lifting rope will be located above the container cylinder after being pulled. Since the thickness of the container cylinder is relatively thin, the container cylinder is easily deformed under the influence of its own weight. In addition, when lifting, the lifting rope needs to be manually passed through the container cylinder. If the position of the cylinder is not fixed, the cylinder is easy to roll, which is dangerous. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing hoisting rope for hoisting a container cylinder has a short service life, is easy to wear, easily causes deformation of the container cylinder, and is also dangerous.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is a lifting device for a pressure vessel, including a container cylinder, and lifting auxiliary equipment is provided on the inner sides of both ends of the container cylinder. The lifting auxiliary equipment includes two discs, and a gear column is rotatably provided between the discs. Four support plates are fixed to the outer sides of the two discs, and four limiting grooves are evenly opened on the side of the support plate close to the gear column. A gear rod meshing with the gear column is slidably provided in the limiting groove.

[0006] As a further solution of the utility model: an adjusting handle is fixed on one side of the gear column through a side disc, which is used to drive the gear column to rotate.

[0007] As a further solution of the utility model: the four gear rods are respectively located in the limiting grooves at different positions on the sides of the four support plates, which can prevent the four gear rods from interfering with each other.

[0008] As a further solution of the utility model: a positioning plate is fixed between the two discs, and an adjusting bolt is rotatably connected to the side surface of the positioning plate through a thread, and a fixed tooth plate is rotatably provided at one end of the adjusting bolt close to the gear, which is used to clamp between the tooth grooves on the side surface of the gear column to prevent it from rotating.

[0009] As a further solution of the utility model: an arc-shaped push rod is fixed to one end of the gear rod, and one side of the arc-shaped push rod is in contact with the inner side of the container cylinder to support the inner side of the container cylinder and prevent it from deforming.

[0010] As a further solution of the utility model: four lifting ears are fixed on one side of a disc, and the container cylinder can be lifted by hooking the lifting ears with external hooks.

[0011] Compared with the prior art, the utility model has the following advantages: the patent adds a lifting auxiliary device, which is used to replace the lifting rope device. The gear column drives the gear rod to make the arc-shaped push rod support the inner wall of the container cylinder to prevent the container cylinder from deformation. By installing it at both ends of the container cylinder, it avoids manually passing the lifting rope through the container cylinder, reducing the danger. In addition, the device and the inner wall of the container cylinder are in surface contact, so the wear is small and the service life is longer than the lifting rope.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0022] Combined with Figure 1-4 It can be known that the structure includes a container cylinder 1, and lifting auxiliary equipment is provided on the inner sides of both ends of the container cylinder 1. The lifting auxiliary equipment includes two discs 2, and a gear column 3 is rotatably provided between the discs 2. Four support plates 4 are fixed to the outer sides of the two discs 2. Four limiting grooves 4.1 are evenly opened on the side of the support plate 4 close to the gear column 3. A gear rod 5 meshing with the gear column 3 is slidably provided in the limiting groove 4.1.

[0023] An adjusting handle 6 is fixed on one side of the gear column 3 through a side disc 2, which is used to drive the gear column 3 to rotate; the four gear rods 5 are respectively located in the limiting grooves 4.1 at different positions on the sides of the four support plates 4, which can prevent the four gear rods 5 from interfering with each other; a positioning plate 7 is fixed between the two discs 2, and an adjusting bolt 8 is rotatably connected to the side of the positioning plate 7. The end of the adjusting bolt 8 close to the gear is rotatably provided with a fixed gear plate 9, which is used to clamp between the tooth grooves on the side of the gear column 3 to prevent it from rotating; an arc-shaped push rod 10 is fixed to one end of the gear rod 5, and one side of the arc-shaped push rod 10 is in contact with the inner side of the container barrel 1 to support the inner side of the container barrel 1 and prevent it from deformation; four lifting ears 11 are fixed to one side of a disc 2, and the lifting ears 11 can be hooked by an external lifting hook to achieve the lifting of the container barrel 1.

[0024] The working principle of the present application is as follows: when hoisting the container barrel, first place the device in the middle of one end of the container barrel 1, and then rotate the adjusting handle 6. The rotation of the adjusting handle 6 will drive the four gear rods 5 meshing with it to move, so that one side of the arc-shaped top rod 10 can contact the inner side of the container barrel 1, and then rotate the adjusting bolt 8 to drive the fixed gear plate 9 to move so that it can be clamped in the tooth groove on the side of the gear column 3, and then hang the hook in the lifting ear 11, and then set the device at the other end of the container barrel 1, and use the same method to fix the device, and then start the gantry crane to lift the container barrel 1, so that the container barrel 1 can be moved.
