Description

Technical Field

[0001] This utility model relates to a lifting tool for an engine, belonging to the field of engine manufacturing technology. Background Technology

[0002] During engine manufacturing, after the product rolls off the production line, it needs to be transferred between different workstations using lifting and process hoisting tools. In existing technologies, the design of engine hoisting tools must fully consider their mechanical properties under lifting and transportation conditions. Typically, simulation analysis of the stress on the hoisting tools is required to optimize the structural design, ensuring that their strength, rigidity, and stability meet the usage requirements, thereby avoiding safety accidents caused by insufficient mechanical properties.

[0003] However, in existing engine lifting devices, the engine is prone to tilting during lifting, causing its lower part to scrape against the uprights of the transfer pallet. Furthermore, after lifting, the engine cannot maintain a horizontal position, and during its descent onto the transfer pallet or trolley, it again scrapes against the pallet / trolley structure due to its non-horizontal state. These scraping phenomena can easily cause surface damage to the engine, affecting product quality and assembly accuracy. Therefore, existing engine lifting devices still have room for improvement in terms of lifting stability and engine protection. Summary of the Invention

[0004] To address the problems existing in the background art, this utility model provides a lifting tool for engines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an engine lifting device, comprising a main support arm, a support block, a lifting lug hook, a hanging lug, a top bracket, a secondary support arm, and a connecting pipe; the main support arm comprises a U-shaped main rod and two support rods, the lower end of the support rod of the main support arm is fixedly connected to one end of the connecting pipe, and the other end of the connecting pipe is fixedly connected to a support block; the two sides of the top bracket are respectively fixedly connected to the upper ends of the corresponding secondary support arms, the lower end of each secondary support arm is respectively fixedly connected to the corresponding lifting lug hook, and the top end of the top bracket is fixedly connected to the hanging lug.

[0006] Furthermore, the main support arm is made of a high-strength alloy.

[0007] Furthermore, the top support is a triangular support made of high-strength alloy.

[0008] Furthermore, the outer sides of both the support block and the lifting lug hook are covered with protective padding.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention, through the combination of a triangular support structure with a top bracket, a secondary support arm, and lifting lug hooks, along with the rigid support of the main support arm and support blocks, ensures that the engine remains stable and vertical throughout the lifting, transfer, and lowering process. This effectively solves the problem of damage caused by the engine's lower part scraping against the transfer pallet / trolley due to loss of posture in existing technologies. Simultaneously, based on the engine's external layout and the position of the lifting lugs, the support points are precisely planned to eliminate interference between the lifting equipment and other engine components, improving the smoothness of the lifting operation and avoiding operational delays or additional losses due to interference. Furthermore, the main support arm, top bracket, and other core components are constructed using high-strength alloy materials, ensuring the lifting equipment's load-bearing capacity and deformation resistance. Combined with wear-resistant elastic protective pads on the outside of the support blocks and lifting lug hooks, this further reduces the risk of engine surface wear. Ultimately, this achieves multiple technical benefits, including improved lifting stability, guaranteed engine appearance and structural integrity, increased production efficiency, and reduced overall costs.

[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0013] An engine lifting device includes a main boom 1, a support block 2, lifting lug hooks 3, hanging lugs 4, a top bracket 5, a secondary boom 6, and a connecting pipe 7. The main boom 1 includes an integrally formed U-shaped main rod and two support rods. The lower end of the support rod of the main boom 1 is fixedly connected to one end of the connecting pipe 7 by welding, and the other end of the connecting pipe 7 is fixedly connected to the support block 2. The two sides of the top bracket 5 are respectively fixedly connected to the upper ends of the corresponding secondary booms 6 by welding, and the lower end of each secondary boom 6 is respectively fixedly connected to the corresponding lifting lug hook 3 by welding. The top end of the top bracket 5 is fixedly connected to the hanging lug 4 by welding.

[0014] Furthermore, the main support arm 1 is made of a high-strength alloy, such as Q345B steel plate, which has sufficient load-bearing and deformation resistance to ensure strength and toughness.

[0015] Furthermore, the top support 5 is a triangular support made of high-strength alloy, such as Q345B steel plate, which precisely constructs the lifting structure, disperses the lifting force, and maintains the engine's posture. It also avoids interference with other engine components, ensuring the engine is horizontal and vertical during lifting and lowering.

[0016] Furthermore, the outer sides of the support block 2 and the lifting hook 3 are covered with protective padding layers. The protective padding layers are made of wear-resistant and elastic rubber material and are cut to fit the shape.

[0017] The working process of this utility model is as follows:

[0018] 1. Preparations before lifting: Reliably connect the lifting lug 4 to the lifting equipment (such as an electric hoist), and check the tightness of each component connection and the integrity of the protective padding. Adjust the lifting support point according to the position of the engine lifting lug to ensure alignment and fit.

[0019] 2. Lifting and Transfer: Operate the lifting equipment to ensure the two lifting lugs 3 align precisely with the two lifting lugs of the engine, locking the hooks in place, and smoothly lift the engine. Observe the engine's posture during the process, using the triangular support structure to ensure horizontal and vertical alignment, and complete the transfer to the transfer pallet, trolley, etc. Maintain the same posture during descent to avoid scratches.

[0020] 3. Maintenance and upkeep: Regularly inspect the structure of the lifting gear, check whether the support arm is deformed, whether the connecting parts are loose, and whether the protective padding is worn. Repair or replace it in time to ensure that the lifting gear can be used reliably for a long time.
