Description

Technical Field

[0001] This utility model relates to the technical field of lifting equipment, and in particular to a lifting fixture. Background Technology

[0002] Lifting fixtures refer to a combination of specialized tools, equipment, and supporting facilities used for lifting operations during construction. They mainly include lifting machinery, lifting gear, rigging, and auxiliary tools, used to lift and move heavy objects to a designated location. Existing technology announcement CN218434531U discloses a large-item lifting fixture, including clamping arm one and clamping arm two, which are hinged together by bolts. Each clamping arm has a support platform at its top, with rollers rotatably connected to the support platform. Corresponding upper sidewalls of clamping arms one and two are connected to the two ends of a compression spring, and hooks are installed on the corresponding upper sidewalls of clamping arms one and two. However, when clamping and lifting cylindrical workpieces such as oil drums, this fixture is prone to displacement and falling, posing significant safety hazards and limitations. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a lifting fixture that facilitates clamping and hoisting of cylindrical workpieces, ensures safety during hoisting, and reduces limitations in use.

[0004] This utility model discloses a lifting fixture, comprising two vertical poles, a supporting component, a protective component, a lifting component, and a disassembly assembly. The supporting component is installed at the bottom of the two vertical poles via the disassembly assembly, and the protective component is installed on the supporting component. The lifting component is installed at the top of the vertical poles. The lifting component is connected to lifting equipment such as a crane or overhead crane to lift the vertical poles. The supporting component clamps and lifts cylindrical workpieces such as oil drums. The protective component protects the top of the supporting component, ensuring safety during lifting and reducing limitations in its use.

[0005] Preferably, the lifting component includes two semi-circular support plates, and the bottom of the vertical rod has an insertion groove. The two semi-circular support plates are respectively located in the insertion grooves at the bottom of the two vertical rods, and a central hole is formed between the two semi-circular support plates. The two semi-circular support plates support and clamp the cylindrical workpieces such as oil drums for hoisting, ensuring the hoisting quality of the cylindrical objects.

[0006] Preferably, the disassembly and assembly assembly includes two connecting pins, two pull plates, and two handles. Connecting holes are provided on the bottom of the vertical rod and the outer wall of the semi-circular support plate. The connecting pins are inserted into the connecting holes, and pull plates are installed on the outer wall of the connecting pins. The upper end of the pull plates is connected to the outer wall of the vertical rod by bolts, and handles are installed on the outer wall of the pull plates. By removing the bolts and pulling the handles, the pull plates can move the connecting pins out of the connecting holes, thereby allowing the semi-circular support plate to be removed from the bottom of the vertical rod. This assembly is suitable for different hoisting conditions and improves practicality.

[0007] Preferably, the protective components include multiple sets of round vertical rods, two protective rods, and two sets of connecting plates. Multiple round vertical rods are installed at the front and rear ends of the top of the semi-circular support plate, and protective rods are installed on the top of the round vertical rods. A connecting plate is installed at the end of the protective rod near the round vertical rod, and the connecting plate is connected to the outer wall of the round vertical rod by bolts. The round vertical rods and protective rods protect the top of the semi-circular support plate, ensuring safety during hoisting. Removing the bolts disconnects the connection between the connecting plate and the round vertical rod, making it easier to remove the semi-circular support plate, which in turn pulls the round vertical rods and protective rods, thus improving convenience.

[0008] Preferably, the lifting components include two lifting rods, two lifting rings, and a lifting chain. The lifting rods are fixedly connected to the top of the vertical rod, and the two lifting rods are rotatably connected in the middle. The top of the lifting rods is provided with lifting holes, and the lifting rings are installed in the lifting holes. The left and right ends of the lifting chain are connected to the lifting rings. The middle part of the lifting chain is connected to a crane or other lifting equipment. The two ends of the lifting chain pull the lifting rods through the lifting rings, so that the two semi-circular support plates at the bottom of the vertical rod come closer to each other and clamp the object, thereby lifting it. At the same time, the lifting chain can limit the opening angle of the bottom of the vertical rod.

[0009] Preferably, it also includes multiple support blocks and two sets of locking pins. Support blocks are installed at the front and rear ends of the bottom of the semi-circular tray. Positioning holes are alternately opened on the side of the two semi-circular trays that are close to each other, and multiple locking pins are installed thereon. When the semi-circular tray is placed on the ground, the support blocks support the semi-circular tray to reduce impact noise. At the same time, the two semi-circular trays are close to each other, which drives the locking pins into the positioning holes, making the connection between the two semi-circular trays tighter and enhancing the stability of the semi-circular tray when supporting items.

[0010] Preferably, it also includes two sets of rubber pads, with rubber pads installed at the ends of the left and right guard bars that are close to each other; the rubber pads can reduce the collision noise when the left and right guard bars are close together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting component is connected to the lifting equipment such as a crane or gantry crane to lift the vertical pole, and the lifting component clamps and lifts cylindrical workpieces such as oil drums. The protective component protects the top of the lifting component, ensuring safety during lifting and reducing limitations in use. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0014] like Figures 1 to 5 As shown, the bottom of the vertical rod 1 has an insertion slot, and two semi-circular support plates 2 are respectively located in the insertion slots at the bottom of the two vertical rods 1. A central hole is formed between the two semi-circular support plates 2. Connection holes are opened on the bottom of the vertical rod 1 and the outer wall of the semi-circular support plates 2. A connecting pin 3 is inserted into the connection hole. A pull plate 4 is installed on the outer wall of the connecting pin 3. The upper end of the pull plate 4 is connected to the outer wall of the vertical rod 1 by bolts. A handle 5 is installed on the outer wall of the pull plate 4. Multiple round vertical rods 8 are installed at the front and rear ends of the top of the semi-circular support plates 2. A protective rod 9 is installed on the top of the round vertical rods 8. The protective rod 9 is close to the vertical rod. One end of the vertical rod 1 is equipped with a connecting plate 10, which is connected to the outer wall of the vertical rod 1 by bolts. The top of the vertical rod 1 is fixedly connected with a lifting rod 12. The two lifting rods 12 are rotatably connected in the middle. The top of the lifting rod 12 is provided with a lifting hole. The lifting ring 13 is installed in the lifting hole. The left and right ends of the lifting chain 14 are connected to the lifting ring 13. The bottom front and rear ends of the semi-circular support plate 2 are equipped with support blocks 6. The two semi-circular support plates 2 have positioning holes alternately opened on the side that is close to each other and multiple locking pins 7 are installed. The left and right protective rods 9 are equipped with rubber pads 11 at the end that is close to each other. The middle of the lifting chain 14 is connected to a crane or other lifting equipment. The lifting chain 14 is pulled by lifting rings 13 at both ends, causing the two semi-circular support plates 2 at the bottom of the vertical rod 1 to clamp each other and lift the object. Simultaneously, the lifting chain 14 limits the opening angle of the bottom of the vertical rod 1. The two semi-circular support plates 2 support and clamp cylindrical workpieces such as oil drums, ensuring the quality of lifting cylindrical objects. The vertical rod 8 and guard rod 9 provide protection above the semi-circular support plates 2, ensuring safety during lifting. The bolts are removed, and the handle 5 is pulled, causing the pull plate 4 to move the connecting pin 3 out of the connecting hole, thus enabling... The semi-circular support plate 2 can be removed from the bottom of the vertical rod 1, which is suitable for different hoisting conditions and improves practicality. The bolts are removed to disconnect the connection plate 10 from the vertical rod 1, making it easier to remove the semi-circular support plate 2 along with the circular vertical rod 8 and the guard rod 9, thus improving convenience. When the semi-circular support plate 2 is placed on the ground, it is supported by the support block 6 to reduce impact noise. At the same time, when the two semi-circular support plates 2 are close together, the locking pin 7 is driven into the positioning hole, making the connection between the two semi-circular support plates 2 tighter and enhancing the stability of the semi-circular support plate 2 when supporting items. The rubber pad 11 can reduce the collision noise when the left and right guard rods 9 are close together.

[0015] like Figures 1 to 5 As shown, this utility model discloses a lifting fixture. During operation, the middle of the lifting chain 14 is connected to a crane or other lifting equipment. The two ends of the lifting chain 14 are pulled by lifting rings 13 to pull the lifting rod 12, causing the two semi-circular support plates 2 at the bottom of the vertical rod 1 to come close together and clamp the object. When the semi-circular support plates 2 are placed on the ground, they are supported by support blocks 6 to reduce impact noise. Simultaneously, the approach of the two semi-circular support plates 2 causes the locking pin 7 to enter the positioning hole, making the connection between the two semi-circular support plates 2 tighter and enhancing the lifting effect. The circular support plate 2 ensures stability when supporting items. The rubber pad 11 reduces collision noise when the left and right guard rods 9 approach each other. The circular vertical rod 8 and guard rod 9 protect the top of the semi-circular support plate 2, ensuring safety during hoisting. By removing the bolts and pulling the handle 5, the pull plate 4 moves the connecting pin 3 out of the connecting hole, thereby allowing the semi-circular support plate 2 to be removed from the bottom of the vertical rod 1. This is suitable for different hoisting conditions. At the same time, removing the bolts disconnects the connection between the connecting plate 10 and the vertical rod 1, making it easier for the semi-circular support plate 2 to move the circular vertical rod 8 and guard rod 9 away.

[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
