AI Technical Summary
Existing lightweight engines are inconvenient to lift during maintenance. The lifting holes are located on both sides of the engine block, causing the lifting hooks to form an angle, which can easily damage the pipes and wiring.
Fixed blocks are set on both sides of the engine body. The fixed blocks are equipped with receiving grooves and guide rods. The sliding block is slidably connected to the guide rod. Through the cooperation of the connecting rod and the lifting block, the sliding block is stably raised and lowered by the magnetic ring adsorption, so as to avoid the hook from rubbing against the top part of the engine cylinder block.
This reduces the probability of secondary damage to pipelines and lines during maintenance and improves the convenience and safety of hoisting.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engine technology, specifically a lightweight engine that is easy to maintain. Background Technology
[0002] Lightweight engines replace traditional cast iron with new materials such as aluminum alloy and carbon fiber. Combined with integrated structural design and 3D printing technology, the overall weight of the engine is significantly reduced compared to traditional engines while ensuring power performance. Engine maintenance often requires lifting the engine. A special lifting frame is used to fix the engine through the cylinder block lifting holes. After slowly separating the gearbox, the entire engine is lifted out.
[0003] Existing lightweight engines still have the following shortcomings: Existing lightweight engines are inconvenient to lift during maintenance. The existing lifting holes are located on both sides of the engine block. The hooks of the lifting bracket hook onto the lifting holes on both sides, so that the iron chains on the hooks on both sides form an angle with each other during lifting. The components on the top of the engine block are prone to scratching the iron chains, causing related pipe deformation or wiring damage, increasing the probability of secondary damage during maintenance. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a lightweight engine that is easy to maintain, solving the problem that existing lightweight engines are inconvenient to hoist during maintenance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-maintain lightweight engine, comprising an engine body, with fixed blocks fixedly connected to both sides of the engine body, a receiving groove opened on the top of the fixed blocks, guide rods fixedly connected to the inner walls of both sides of the receiving groove, a sliding block slidably connected to each guide rod, a pair of connecting blocks fixedly connected to the top of the sliding blocks, a connecting rod rotatably connected between the pair of connecting blocks, a lifting block rotatably connected to one end of the connecting rod, a connecting shaft rotatably connected to the top of the lifting block, and a lifting ring fixedly connected to the top of the connecting shaft.
[0006] As a further embodiment of this utility model: a limiting strip is fixedly connected to the inner bottom of the receiving groove, and one end of the guide rod is fixedly connected to the limiting strip.
[0007] As a further embodiment of this utility model: both ends of the limiting strip are provided with annular grooves, and a magnetic ring is fixedly connected inside the annular grooves.
[0008] As a further embodiment of this utility model: an annular groove II is provided on the side of the sliding block near the limiting strip, and a magnetic ring II is fixedly connected inside the annular groove II.
[0009] As a further embodiment of this utility model: a pair of guide rails are fixedly connected to the inner walls on both sides of the receiving groove, and the ends of the pair of guide rails that are close to each other are fixedly connected to the limiting strip.
[0010] As a further embodiment of this utility model: sliding grooves are provided on both sides of the sliding block, and the sliding grooves are adapted to the corresponding guide rails.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This utility model includes a fixed block, a receiving groove, a guide rod, a sliding block, a connecting block, a connecting rod, a lifting block, a lifting ring, and a limiting strip. In the initial state, the lifting block rests on top of the fixed block, placing the lifting ring at the lowest point to facilitate the connection of relevant pipelines of the engine body. When the engine body needs to be lifted, the lifting ring is pulled upwards, and the lifting ring drives the lifting block to rise through the connecting shaft. The lifting block pulls a pair of connecting blocks through the connecting rod, and the pair of connecting blocks drive the sliding block to slide along the corresponding guide rod. The pair of sliding blocks move closer to each other until the sliding block touches the limiting strip. At this time, the lifting block is fully raised, and the height of the lifting ring exceeds that of the engine body. When using a hook to hook the lifting ring for lifting, the iron chain on the hook will not rub against the components on the top of the engine block, reducing the probability of secondary damage during maintenance.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] like Figures 1-5 As shown, this utility model provides a technical solution:
[0021] A lightweight, easily maintainable engine includes an engine body 1. Fixed blocks 2 are fixedly connected to both sides of the engine body 1. A receiving groove 3 is formed on the top of each fixed block 2. Guide rods 4 are fixedly connected to the inner walls of both sides of the receiving groove 3. A sliding block 5 is slidably connected to each guide rod 4. A pair of connecting blocks 6 are fixedly connected to the top of each sliding block 5. A connecting rod 7 is rotatably connected between the pair of connecting blocks 6. A lifting block 8 is rotatably connected to one end of the connecting rod 7. A connecting shaft is rotatably connected to the top of the lifting block 8. A lifting ring 9 is fixedly connected to the top of the connecting shaft. In the initial state, the sliding block 5 is in contact with the corresponding side wall of the receiving groove 3, and the lifting block 8 is... At the top of the fixed block 2, the lifting ring 9 is positioned at the lowest point, facilitating the connection of relevant pipelines of the engine body 1. When the engine body 1 needs to be lifted, the lifting ring 9 is pulled upwards. The lifting ring 9 drives the lifting block 8 to rise through the connecting shaft. The lifting block 8 pulls a pair of connecting blocks 6 through the connecting rod 7. The pair of connecting blocks 6 drive the sliding block 5 to slide along the corresponding guide rod 4. The pair of sliding blocks 5 move closer to each other. When the lifting block 8 is fully raised, the height of the lifting ring 9 exceeds that of the engine body 1. At this time, when the lifting ring 9 is hooked by the hook for lifting, the iron chain on the hook will not rub against the parts on the top of the engine cylinder block, reducing the probability of secondary damage during maintenance.
[0022] A limiting strip 10 is fixedly connected to the bottom of the receiving groove 3. One end of the guide rod 4 is fixedly connected to the limiting strip 10. Both ends of the limiting strip 10 are provided with annular groove 1. A magnetic ring 11 is fixedly connected inside the annular groove 1. An annular groove 2 is provided on the side of the sliding block 5 near the limiting strip 10. A magnetic ring 2 12 is fixedly connected inside the annular groove 2. The sliding block 5 slides along the guide rod 4 until the sliding block 5 abuts against the limiting strip 10. The magnetic poles of the magnetic ring 11 and the magnetic ring 2 12 are different on the side that are close to each other. After the magnetic ring 11 and the magnetic ring 2 12 come into contact, they will be tightly attracted together, so that the sliding block 5 and the limiting strip 10 remain in contact. The position of the lifting block 8 and the lifting ring 9 on it remains unchanged, which is convenient for hoisting.
[0023] A pair of guide rails 13 are fixedly connected to the inner walls on both sides of the receiving groove 3. The ends of the pair of guide rails 13 that are close to each other are fixedly connected to the limiting strip 10. Sliding grooves are provided on both sides of the sliding block 5. The sliding grooves are adapted to the corresponding guide rails 13. The sliding grooves on both sides of the sliding block 5 slide along the corresponding guide rails 13 to prevent the sliding block 5 from rotating on the guide rod 4.
[0024] The working principle of this utility model is as follows:
[0025] In the initial state, the sliding block 5 contacts the corresponding side wall of the receiving groove 3, and the lifting block 8 rests on the top of the fixed block 2, so that the lifting ring 9 is at the lowest point, which facilitates the connection of the relevant pipelines of the engine body 1. When the engine body 1 needs to be lifted, the lifting ring 9 is pulled upward. The lifting ring 9 drives the lifting block 8 to rise through the connecting shaft. The lifting block 8 pulls a pair of connecting blocks 6 through the connecting rod 7. The pair of connecting blocks 6 drive the sliding block 5 to slide along the corresponding guide rod 4. The sliding grooves on both sides of the sliding block 5 slide along the corresponding guide rail 13 to prevent the sliding block 5 from rotating on the guide rod 4. The pair of sliding blocks 5 move closer to each other until the sliding block 5 touches the limit strip 10. At this time, the lifting block 8 is fully raised and the height of the lifting ring 9 exceeds that of the engine body 1. When the lifting ring 9 is hooked by the hook for lifting, the iron chain on the hook will not scratch the parts on the top of the engine cylinder block, reducing the probability of secondary damage during maintenance.
[0026] The magnetic poles of magnetic ring 11 and magnetic ring 12 are different on the side that are close to each other. After magnetic ring 11 and magnetic ring 12 come into contact, they will be tightly attracted together, so that the sliding block 5 and the limiting strip 10 remain in contact, and the position of the lifting block 8 and the lifting ring 9 on it remains unchanged, which facilitates hoisting.
[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
