Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a rapid hoisting device for a porous boron carbide hot pressing mold. Background Technology

[0002] The working principle of boron carbide hot pressing mold is mainly based on hot pressing sintering technology. During the hot pressing sintering process, dry and uniformly mixed boron carbide powder is filled into a high-strength graphite mold. While heating, pressure is applied from a uniaxial direction. It is a sintering method that combines forming and sintering. The opening and closing of the mold requires the use of a hoisting device.

[0003] Existing hoisting devices have the problem of limited hoisting methods and are not suitable for hoisting different molds. Therefore, a rapid hoisting device for porous boron carbide hot pressing molds is needed. Utility Model Content

[0004] The purpose of this invention is to provide a rapid hoisting device for porous boron carbide hot pressing molds, which solves the problem that the existing technology has a single hoisting method and is not convenient to adapt to different mold hoisting needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid hoisting device for a porous boron carbide hot pressing mold, comprising a lifting plate, an integrally formed top connecting block on the top of the lifting plate, symmetrically provided limit openings on both sides of the top connecting block, a horizontally arranged crossbar on the top of the top connecting block, a hook penetrating through the middle of the top connecting block, a connecting rod annularly arranged around the periphery of the lifting plate, a connecting strip connected to the top end of the connecting rod, a connecting piece connected to the bottom end of the connecting strip, a transition piece rotatably mounted on the bottom end of the connecting piece, a limit bolt penetrating vertically through the middle of the transition piece, a mold body arranged below the lifting plate, a connecting hole opened on the top of the mold body, symmetrically provided extension ears on both sides of the mold body, a fixing ring buckle at the bottom center of the lifting plate, and a lifting strap penetrating through the middle of the fixing ring buckle.

[0006] Preferably, the width of the limiting opening is slightly larger than the width of the hook, and the hook forms an engaging structure with the top connecting block through the crossbar.

[0007] Preferably, the connecting rods are arranged in four sets around the periphery of the lifting plate, and each connecting rod has a corresponding connecting strap installed on its outer side.

[0008] Preferably, the connector is U-shaped and is rotatably connected to the adapter.

[0009] Preferably, the limiting bolt and the adapter are rotatably connected, and the limiting bolt and the connecting hole are threadedly connected.

[0010] Preferably, the two ends of the lifting strap are respectively connected to the two extension ears, and the middle section of the lifting strap is installed through the middle of the fixing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a bracket, the hook is inserted through the center of the limiting port and engaged with the crossbar during use. The limiting port ensures that the hook can pass through stably and facilitates disassembly and assembly. The top blocks on both sides effectively limit the hook, ensuring that the hook will not slide or deviate along the crossbar after connection and during lifting. This ensures the overall stability of the hoisting center and avoids the tilting that often occurs with simple rope hoisting, thus improving safety. In addition, the connecting rod has four sets of rings around the outer side of the crossbar, which also ensures balance during hoisting connection.

[0013] 2. By setting limit bolts, and then selecting the appropriate connection method according to different usage conditions, when the top of the mold body is provided with connection holes, an appropriate number of limit bolts can be threaded and installed to the corresponding connection holes, and the lifting plate can be connected to the connecting rod through the connecting strap, so that the lifting plate can complete the lifting and moving operation through the top hook. The bottom of the lifting plate is provided with a fixing ring buckle. When the mold body is provided with extension ears, the two ends of the lifting strap passing through the middle can be sleeved on the outside of the extension ears as needed, and the lifting operation can be completed through the top lifting. The appropriate connection method can be flexibly selected according to different situations, and multiple connection methods can be selected when conditions permit, which can ensure that the lifting is more stable and safe.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown in the figure, a rapid hoisting device for a porous boron carbide hot pressing mold includes a lifting plate 1. A top connecting block 2 is integrally provided on the top of the lifting plate 1. Limiting holes 3 are symmetrically opened on both sides of the top connecting block 2. A horizontal bar 4 is provided on the top of the top connecting block 2. A hook 5 passes through the middle of the top connecting block 2. A connecting rod 6 is arranged in a ring around the periphery of the lifting plate 1. The top end of a connecting strip 7 is connected to the outside of the connecting rod 6. A connecting piece 8 is connected to the bottom end of the connecting strip 7. A transition piece 9 is installed horizontally and rotatably at the bottom end of the connecting piece 8. A limit bolt 10 passes vertically through the middle of the transition piece 9. A mold body 11 is provided below the lifting plate 1. A connecting hole 12 is opened on the top of the mold body 11. Extension ears 13 are symmetrically arranged on both sides of the mold body 11. A fixing ring 14 is provided at the center of the bottom of the lifting plate 1. A lifting strap 15 passes through the middle of the fixing ring 14.

[0020] The width of the limiting port 3 is slightly larger than the width of the hook 5. The hook 5 forms a locking structure with the crossbar 4 and the top connecting block 2. The opening of the limiting port 3 ensures that the hook 5 can pass through stably and is easy to disassemble and assemble. The top connecting blocks 2 on both sides effectively limit the hook 5, ensuring that the hook 5 will not slide or deviate along the crossbar 4 after connection and during the lifting process.

[0021] There are four sets of connecting rods 6 arranged in a ring around the outer periphery of the lifting platform 1, and each connecting rod 6 is equipped with a corresponding connecting strap 7 on its outer side. The four sets of connecting rods 6 arranged in a ring around the outer periphery of the crossbar 4 also ensure the balance during hoisting and connection.

[0022] The connector 8 adopts a U-shaped design, and the connector 8 and the adapter 9 are rotatably connected to ensure the stability of the connection, making the tension more even, and the rotatable design makes it easy to adapt to the installation and lifting of molds of different specifications.

[0023] The limit bolt 10 is rotatably connected to the adapter 9, and the limit bolt 10 is threadedly connected to the connecting hole 12. A suitable number of limit bolts 10 can be installed by threading them to the corresponding connecting holes 12, and the lifting plate 1 is connected to the connecting rod 6 through the connecting strap 7.

[0024] The two ends of the lifting strap 15 are respectively connected to the two extension ears 13, and the middle section of the lifting strap 15 passes through the middle of the fixing ring 14. As needed, the two ends of the lifting strap 15 passing through the middle can be connected to the outside of the extension ears 13, and the hoisting operation can be completed by lifting from the top. The appropriate connection method can be flexibly selected according to different situations.

[0025] Working principle: First, when in use, the hook 5 is inserted through the middle of the limiting port 3 and engaged with the crossbar 4. The opening of the limiting port 3 ensures that the hook 5 can pass through stably and facilitates disassembly and assembly. The top connecting blocks 2 on both sides effectively limit the hook 5, ensuring that the hook 5 will not slide or deviate along the crossbar 4 after connection and during lifting, ensuring the overall stability of the hoisting center and avoiding the tilting that often occurs in simple rope hoisting, thus improving the safety of use. In addition, the connecting rod 6 has four sets of rings on the outer side of the crossbar 4, which also ensures the balance during hoisting connection.

[0026] Next, select the appropriate connection method according to different usage conditions. When the top of the mold body 11 is provided with a connection hole 12, a suitable number of limit bolts 10 can be threadedly connected to the corresponding connection hole 12 and connected to the lifting plate 1 through the connecting strap 7 and the connecting rod 6, so that the lifting plate 1 can complete the lifting and moving operation through the top hook 5. The bottom of the lifting plate 1 is provided with a fixing ring buckle 14. When the mold body 11 is provided with an extension ear 13, the two ends of the lifting strap 15 passing through the middle can be sleeved on the outside of the extension ear 13 as needed, and the lifting operation can be completed by lifting from the top. The appropriate connection method can be flexibly selected according to different situations, and multiple connection methods can be selected when conditions permit, which can ensure that the lifting is more stable and safe.
