Description

Technical Field

[0001] This utility model belongs to the field of lifting tools, specifically relating to a special tool for lifting cylinder heads. Background Technology

[0002] As the core of a ship's propulsion system, the main engine's operating condition directly affects the ship's navigation safety and efficiency. Therefore, in the daily maintenance of ships, it is necessary to regularly inspect the main diesel engine to ensure the ship can sail safely.

[0003] However, overhauling existing marine main engines, particularly main diesel engines, often presents numerous challenges. Specifically, the sheer number and weight of the cylinder heads make the entire lifting operation a considerable undertaking. Furthermore, the lack of suitable specialized cylinder head lifting tools forces workers to rely on simple bolts for the lifting process. Workers first use bolts mounted on the top of the cylinder head to connect the lifting straps to it, then adjust the positions of the various straps and lifting rings to balance the cylinder head and the overall lifting structure, thus maintaining cylinder head equilibrium.

[0004] Therefore, in its practical application, it suffers from low efficiency and slows down the progress of the project, which seriously affects the overall progress of the ship's main engine maintenance work. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a special tool for cylinder head hoisting, which can assist workers in hoisting the cylinder head of the main diesel engine, thereby reducing the labor intensity of workers and improving the hoisting and maintenance efficiency of the cylinder head.

[0006] To solve the aforementioned technical problems, the technical solution provided by this utility model is as follows: a special tool for cylinder head hoisting, comprising a left support side plate and a right support side plate arranged opposite to each other, a hoisting beam connecting the left and right support side plates, the left end of the hoisting beam extending out of the left support side plate and connected to a left auxiliary side plate, and a left-side hoisting space existing between the left auxiliary side plate and the left support side plate; the right end of the hoisting beam extending out of the right support side plate and connected to a right auxiliary side plate, and a right-side hoisting space existing between the right auxiliary side plate and the right support side plate; connecting seats are provided at the bottom of both the left and right support side plates, with bolt holes penetrating the connecting seats and connecting them to the cylinder head to be hoisted through these bolt holes, thereby achieving the hoisting of the cylinder head. Thus, when using this utility model to hoist a cylinder head, the connecting seats can first be connected to the cylinder head using bolts, and then the slings can be passed through the left and right hoisting spaces to achieve the hoisting operation of the cylinder head. Moreover, in the above process, since this utility model constrains the lifting position of the entire lifting tool, it can simplify the center of gravity adjustment steps in the entire lifting process, thereby improving the efficiency of lifting and maintenance.

[0007] Furthermore, two connecting seats are provided at the bottom of both the left and right support side plates, and the distance between the two connecting seats on the same support side plate is adapted to the size of the bolt mounting holes provided on the corresponding cylinder head.

[0008] Furthermore, both the left and right support side plates are quadrilaterals, with the bottom edge of the quadrilaterals being horizontal and the top edge being inclined. The upper end of the side located at the high end of the top edge of the quadrilateral is inclined towards the direction close to the low end of the top edge, while the upper end of the side located at the low end of the top edge of the quadrilateral is inclined away from the high end of the top edge. The hoisting beam is located at the high end of the top edge of the quadrilateral to achieve the purpose of adjusting the center of gravity.

[0009] Furthermore, a reinforcing beam connects the lower end of the top edge of the left support side plate and the lower end of the top edge of the right support side plate, thereby enhancing the connection strength between the left and right support side plates.

[0010] Furthermore, the left end of the reinforced beam extends beyond the left support side plate and connects to the left auxiliary side plate, and the right end of the reinforced beam extends beyond the right support side plate and connects to the right auxiliary side plate, thereby improving the overall connection strength.

[0011] Furthermore, the lifting beam and reinforcing beam are hollow tubes, preferably hollow seamless steel tubes, so as to meet the requirements of high load-bearing strength and lightweight and flexible use, and have the characteristics of stable support, convenient cylinder head lifting, balanced center of gravity and high safety factor.

[0012] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model has the characteristics of stable support, convenient cylinder head hoisting, balanced center of gravity, and high safety factor. It can also assist workers in hoisting the cylinder head of the main diesel engine, thereby reducing the labor intensity of workers, improving the hoisting and maintenance efficiency of the cylinder head, and reducing safety hazards in the maintenance process of the main diesel engine.

[0017] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] like Figure 1 , Figure 2 As shown, this utility model provides a special tool for cylinder head hoisting, which includes a left support side plate 1 and a right support side plate 5 arranged in parallel. The shape of the left support side plate 1 and the right support side plate 5 are both quadrilaterals. The bottom edge of the quadrilateral is horizontal and preferably 270cm long. The top edge of the quadrilateral is inclined and preferably 200cm long. The upper end of the side of the quadrilateral located at the high end of the top edge is inclined towards the direction close to the low end of the top edge and preferably 350cm long. The upper end of the side of the quadrilateral located at the low end of the top edge is inclined away from the high end of the top edge and preferably 170cm long.

[0019] Furthermore, connecting seats 2 are provided at the two included corner positions at the bottom of the left support side plate 1 and the two included corner positions at the bottom of the right support side plate 5. Bolt holes are passed through the upper and lower surfaces of the connecting seats 2, and the distance between the two connecting seats 2 located on the same support side plate is adapted to the size of the corresponding cylinder head, so that they can be connected to the cylinder head to be hoisted through the bolt holes to realize the hoisting of the cylinder head.

[0020] A lifting beam 7 connects the high-end position of the top edge of the left support side plate 1 and the high-end position of the top edge of the right support side plate 5. The left end of the lifting beam 7 extends out of the left support side plate 1 and connects to the left auxiliary side plate 3, and there is a left-side hanging space between the left auxiliary side plate 3 and the left support side plate 1; the right end of the lifting beam 7 extends out of the right support side plate 5 and connects to the right auxiliary side plate 6, and there is a right-side hanging space between the right auxiliary side plate 6 and the right support side plate 5. Thus, the left-side hanging space and the right-side hanging space provide a hanging position for the lifting strap to meet the balanced suspension of the cylinder head.

[0021] Meanwhile, this utility model also connects a reinforcing beam 4 between the lower end of the top edge of the left support side plate 1 and the lower end of the top edge of the right support side plate 5. The left end of the reinforcing beam 4 extends out of the left support side plate 1 and connects to the left auxiliary side plate 3, and the right end of the reinforcing beam 4 extends out of the right support side plate 5 and connects to the right auxiliary side plate 6, thereby improving the overall connection strength through the reinforcing beam 4. Moreover, preferably, both the hoisting beam 7 and the reinforcing beam 4 are hollow tubes, and preferably hollow seamless steel tubes are used to meet the requirements of high load-bearing strength and lightweight and flexible use.

[0022] Based on this, when using this invention to lift cylinder heads, the connecting seat 2 can be connected to the cylinder head using bolts first, and then the lifting straps can be passed through the left and right lifting spaces to achieve the lifting operation of the cylinder head. Moreover, in the above process, since this invention has constrained the lifting position of the entire lifting tool through the support side plates and auxiliary side plates on both sides, and has adjusted the shape of the support side plates, it can simplify the center of gravity adjustment steps in the entire lifting process, thereby improving the efficiency of lifting and maintenance.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
