Description

Technical Field

[0001] This utility model relates to the field of expansion tank technology, and more specifically, to a novel winch gear oil expansion tank. Background Technology

[0002] In marine equipment, cranes play an irreplaceable role as crucial auxiliary equipment in daily ship operations. They require stable performance during the handling of large equipment and the transfer of materials. Therefore, cranes are a key maintenance item in routine ship maintenance, and the winch gears, which serve as the crane's power source, are of paramount importance.

[0003] Modern marine cranes are mostly hydraulically driven. A hydraulic pump delivers hydraulic oil to the winch gears, driving them for energy exchange. Gear oil is responsible for lubrication and heat dissipation between the gears. During operation, air bubbles and heat can occur. Prolonged air bubble accumulation can lead to cavitation on the metal surfaces, and overheating can accelerate the aging of the gear seals. The winch gear expansion tank avoids these problems. Connected to the winch gears via a sealing ring, the expansion tank prevents thermal expansion and contraction of the gear oil during use, maintaining a stable oil pressure. Direct heat exchange with the external environment through the expansion tank slows down oil deterioration. A vent at the top allows air bubbles generated during gear operation to escape, while a side observation port allows for monitoring of the oil quality and level, facilitating routine maintenance.

[0004] Because expansion tanks are made entirely of iron, prolonged exposure to sea winds can cause them to rust and perforate, leading to gear oil leaks and shortening the lifespan of the expansion tubing. Simple vents, while allowing air to escape, can also allow rainwater and mist to enter the tank and contaminate the lubricating oil, failing to protect the gear oil inside and instead causing it to deteriorate and result in greater losses. Furthermore, since expansion tanks are typically fixed to ship equipment, they lack cushioning when impacted by external objects, making them susceptible to damage. Utility Model Content

[0005] The purpose of this utility model is to address the problems of existing winch gear oil expansion tanks where rainwater can flow back into the expansion tank during the venting process, causing oil contamination, and the tank body is easily damaged by collisions with external objects.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A novel winch gear oil expansion tank includes a tank body and an oil pipe disposed at the bottom of the tank body, and further includes:

[0008] The protective mechanism includes a movable part disposed on the top of the tank and a buffer part disposed on the outside of the tank;

[0009] The movable component includes a mounting plate, a rotating plate rotatably disposed in a movable groove inside the mounting plate, and a reset component disposed at the contact end between the mounting plate and the rotating plate. The end of the rotating plate away from the mounting plate is connected to the top of the tank.

[0010] As a preferred technical solution of this application, the tank body includes a hollow cylinder and an upper cover and a lower cover welded to the top and bottom of the hollow cylinder respectively, wherein the hollow cylinder, the upper cover and the lower cover are made of 304 stainless steel.

[0011] As a preferred technical solution of this application, the top of the cover is provided with a breathable cap.

[0012] As a preferred technical solution of this application, the hollow cylinder sidewall is provided with two symmetrical observation holes.

[0013] As a preferred technical solution of this application, the reset component includes support blocks disposed at the top and bottom of the mounting plate, a rotating shaft rotatably disposed between the two support blocks and passing through the mounting plate, and a torsion spring sleeved on the rod wall of the rotating shaft located between the support blocks and the mounting plate, wherein one end of the rotating plate is fixedly connected to the outside of the vent cap, and the other end of the rotating plate is fixedly connected to the rotating shaft.

[0014] As a preferred technical solution of this application, the buffer component includes support sleeves disposed on the outer walls of both sides of the hollow cylinder and several rubber cylinders rotatably disposed between the two support sleeves.

[0015] As a preferred technical solution of this application, the buffer component further includes a plurality of mounting heads rotatably disposed on opposite sides of the two support sleeves and a rotating rod rotatably disposed between the two opposite mounting heads, and the rubber cylinder is fixedly disposed outside the rotating rod.

[0016] As a preferred technical solution of this application, the mounting plate is provided with a positioning plate at the end away from the tank body, and the surface of the positioning plate is provided with a number of positioning bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By installing a vent cap on the top of the tank, air can be vented from the inside of the tank while preventing rainwater from flowing back into the tank. This prevents rainwater from contaminating the oil inside the tank. Furthermore, the observation hole allows for easy monitoring of the gear oil quality and level, facilitating daily maintenance by repair personnel. In addition, the tank, made of 304 stainless steel, has better rigidity, can withstand greater impact and pressure, has higher strength, and is not easily damaged. The metal also has good thermal conductivity, which increases the service life of the oil.

[0019] 2. When an external object collides with the tank, the movable parts can rotate the tank to prevent a hard collision between the tank and the external object. In addition, the buffer parts can not only cushion and protect the tank, but also work with the rotating tank to create a force-dissipating effect, causing the object that collides with the tank to quickly move away from the tank, thereby protecting the tank and improving the service life of the equipment.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figures 1 to 4 As shown, this embodiment proposes a novel winch gear oil expansion tank, including a tank body 1 and an oil pipe disposed at the bottom of the tank body 1, and also includes a protective mechanism. The protective mechanism includes a movable part 4 disposed at the top of the tank body 1 and a buffer part 5 disposed outside the tank body 1. When the tank body 1 is impacted by an external object, the movable part 4 can cause the impacted tank body 1 to rotate. In addition, the buffer part 5 can also buffer and protect the impacted tank body 1 and produce a force-dissipating effect, causing the impacting object to quickly move away from the tank body 1, thereby protecting the tank body and improving the service life of the tank body 1.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the tank body 1 further includes a hollow cylinder 101 and an upper cover 102 and a lower cover 103 respectively welded to the top and bottom of the hollow cylinder 101. The hollow cylinder 101, the upper cover 102 and the lower cover 103 are made of 304 stainless steel. The top of the upper cover 102 is provided with a vent cap 2. The side wall of the hollow cylinder 101 is provided with two symmetrical observation holes 3.

[0031] By installing a vent cap 2 on the top of the tank 1, with its vent hole located on the side and a baffle on the top, venting can be performed on the inside of the tank 1 while preventing rainwater from flowing back into the tank 1. This prevents rainwater from contaminating the oil inside the tank 1. Furthermore, the observation hole 3 allows for easy monitoring of the gear oil quality and level, facilitating daily maintenance by repair personnel. In addition, the tank 1, made of 304 stainless steel, has better rigidity, can withstand greater impact and pressure, has higher strength, and is not easily damaged. The metal also has good thermal conductivity, thereby increasing the service life of the oil. It should be noted that the shape of the tank 1 in this application is basically the same as that of the iron expansion tank in the prior art. The tank is made of 304 stainless steel, and the original vent hole is replaced by a vent cap 2. The vent cap 2 and the tank 1 are sealed by pressing an oil-resistant rubber ring with threads. The specific structural components are as follows: A hollow cylinder with a radius of 45mm, a thickness of 2mm, and a length of 135mm is cut. Two 45-degree chamfers are made on both sides of the cylinder, parallel to the cylinder axis. Two 9mm radius holes are drilled, with a center distance of 80mm between the two holes, centered on the midpoint of the axis. Two semi-elliptical caps with a minor diameter of 25mm and a major diameter of 45mm are machined, with center holes of 18mm and 12mm respectively. The edges of the two elliptical caps are chamfered at 45 degrees. Solid cylinders with outer diameters of 26mm and 20mm are machined, with M18*2.5 and M12*1.75 threaded holes machined internally respectively. One side of each cylinder is chamfered at 10 degrees, and they are seamlessly welded to the elliptical caps. Two elliptical caps are welded to a hollow cylinder to create a solid cylinder with an outer diameter of 26m. An M18*2.5 threaded hole is machined inside the cylinder, and a 5-degree chamfer is cut inside the center of one side of the cylinder. The cylinder is then seamlessly welded to the hollow cylinder using laser welding.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the movable component 4 further includes a mounting plate 401, a rotating plate 402 rotatably disposed in the movable groove inside the mounting plate 401, and a reset component disposed at the contact end between the mounting plate 401 and the rotating plate 402. The end of the rotating plate 402 away from the mounting plate 401 is connected to the top of the tank body 1.

[0033] The reset component includes support blocks 405 disposed at the top and bottom of the mounting plate 401, a rotating shaft 406 rotatably disposed between the two support blocks 405 and passing through the mounting plate 401, and a torsion spring 407 sleeved on the rod wall of the rotating shaft 406 located between the support blocks 405 and the mounting plate 401. One end of the rotating plate 402 is fixedly connected to the outside of the vent cap 2, and the other end of the rotating plate 402 is fixedly connected to the rotating shaft 406.

[0034] When the tank 1 is impacted by an external object, the tank 1 will rotate on the mounting plate 401 via the rotating plate 402, causing the rotating shaft 406 and the torsion spring 407 to twist, preventing the tank 1 from being damaged by a hard collision with the external object while it is stationary. When the external object moves away from the tank 1, the torsion spring 407 will be released from its force, causing the rotating shaft 406 to reverse and reset, which in turn causes the rotating plate 402 and the tank 1 to reverse and reset to their initial positions, thereby improving the service life of the tank 1.

[0035] In addition, a positioning plate 403 is provided at the end of the mounting plate 401 away from the tank body 1, and a number of positioning bolts 404 are threaded on the surface of the positioning plate 403; the tank body 1 can be fixed in the designated position of the ship by means of the positioning bolts 404 and the positioning plate 403.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the buffer component 5 further includes support sleeves 501 disposed on the outer walls of both sides of the hollow cylinder 101 and a plurality of rubber cylinders 502 rotatably disposed between the two support sleeves 501.

[0037] The buffer component 5 also includes several mounting heads 503 rotatably disposed on opposite sides of the two support sleeves 501 and a rotating rod 504 rotatably disposed between the two opposite mounting heads 503, with the rubber cylinder 502 fixedly disposed outside the rotating rod 504.

[0038] When an external object collides with the tank 1, multiple rubber cylinders 502 can be installed to buffer and protect the outside of the tank 1. When the rubber cylinders 502 come into contact with the external object, they will rotate due to friction. The entire tank 1 will also rotate through the rotating plate 402, which can produce a force-dissipating effect, causing the external object to slide along the outside of the tank 1 and quickly move away from the tank 1, thereby further protecting the tank 1.

[0039] The working principle of this utility model is as follows: By setting a vent cap 2 on the top of the tank 1, air can be vented from the inside of the tank 1 while preventing rainwater from flowing back into the tank 1, thus preventing rainwater from contaminating the oil inside the tank 1. Furthermore, the observation hole 3 allows for easy monitoring of the gear oil quality and level, facilitating daily maintenance by repair personnel. In addition, the tank 1, made of 304 stainless steel, has better rigidity, can withstand greater impact and pressure, has higher strength, and is less prone to damage. The metal also has good thermal conductivity, further increasing the service life of the oil. When the tank 1 is impacted by an external object, the tank 1 will rotate on the mounting plate 401 via the rotating plate 402, causing the rotating shaft 406 and the torsion bar to... The torsion spring 407 twists to prevent the can 1 from being damaged by a hard collision with an external object while it remains stationary. At the same time, the multiple rubber cylinders 502 provide buffer protection for the outside of the can 1. When the rubber cylinders 502 come into contact with the external object, they will rotate due to friction. The entire can 1 will also rotate through the rotating plate 402, which will produce a force-relieving effect, causing the external object to slide along the outside of the can 1 and quickly move away from the can 1, thus further protecting the can 1. Finally, when the external object moves away from the can 1, the torsion spring 407 is released from its force, which will drive the rotating shaft 406 to reverse and reset, thereby driving the rotating plate 402 and the can 1 to reverse and reset to their initial positions, thus improving the service life of the can 1.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
