Description

Technical Field

[0001] The present invention relates to the technical field of refueling devices, and more particularly to a clean refueling device. Background Art

[0002] In the production equipment of various industries, various types of reducers or hydraulic devices are usually used. These equipments have different specifications and require different lubricating oil or hydraulic oil capacities. At the same time, the installation positions and heights of these equipments are different, which increases the difficulty of refueling. For example, the installation height of the final polymerization reducer of the polyester device in the chemical fiber industry is about 3 meters from the ground, and the refueling volume is about 550L.

[0003] The oil filling method for the final polymerization reducer is usually to use an oil suction pump or an oil barrel. The oil suction pump filling method is to use an oil suction pump to extract the lubricating oil from the oil barrel and discharge it directly into the reducer. Usually, some lubricating oil will remain in the oil barrel and cannot be extracted, causing waste; the oil barrel filling method is for the oiler to extract the lubricating oil from the oil barrel and discharge it into the oil filling barrel. The lubricating oil in the oil filling barrel is filtered and then injected into the reducer. During the oil filling process, the oiler needs to climb to a height of 3 meters with the oil filling barrel in hand, and squat on the top of the reducer to inject oil into the reducer.

[0004] The above two operation methods have the following disadvantages: first, there is oil leakage during the oil filling process, which makes the ground slippery and there is a risk of slipping; second, the workload is large and the efficiency is low; third, some lubricating oil will remain in the oil barrel and cannot be extracted, resulting in waste.

[0074] Example 2: Figures 17 to 20 As shown, the structure of this embodiment is similar to that of embodiment 1, except that at least two hook assemblies 4-9 are connected to the top of the chain 4-4, and the hook assemblies 4-9 can cooperate with the flange at the top of the oil barrel 5 to lift the oil barrel 5.

[0075] Specifically, the hook assembly 4-9 includes a crank ring 4-9-1, a locking hook 4-9-2 and a hook pin 4-9-3. The crank ring 4-9-1 is a bent rod-shaped structure with a ring at the top. A central through hole 4-9-4 is provided in the middle of the crank ring 4-9-1. Both ends of the crank ring 4-9-1 are symmetrically bent into an obtuse structure with the central through hole 4-9-4 as the center. A ring is welded at one end of the crank ring 4-9-1. The locking hook 4-9-2 is a thick steel plate of a U-shaped structure of unequal width. The narrower end of the locking hook 4-9-2 It is a hook head, and a lock hook through hole 4-9-5 is provided at the end of the wider end of the lock hook 4-9-2, and a through groove is opened in the middle of the wider end of the lock hook 4-9-2. The crank at the central through hole of the crank ring 4-9-1 is sleeved inside the through groove of the lock hook 4-9-2, and the hook pin 4-9-3 passes through the central through hole of the crank ring 4-9-1 and the lock hook through hole 4-9-5 of the lock hook 4-9-2. The crank ring 4-9-1 can rotate freely in the through groove of the lock hook 4-9-2, and the rotation angle is greater than 90°.

[0076] When in use, turn over the crank ring 4-9-1 so that the non-ring end of the crank ring 4-9-1 is parallel to the hook head of the locking hook 4-9-2, and put the locking hook 4-9-2 on the outer side of the top flange of the oil drum 5, and turn over the crank ring 4-9-1 again so that the crank at the non-ring end of the crank ring 4-9-1 is stuck into the inner side of the top flange of the oil drum 5. When lifting, the crank ring 4-9-1 is subjected to force to lock the crank ring 4-9-1 and the locking hook 4-9-2 to ensure safe lifting.

[0077] Example 3: Figure 21 to Figure 24 As shown, the structure of this embodiment is similar to that of embodiment 1 or embodiment 2, except that the first spring pin 4-8-5, the second spring pin 2-3 and the third spring pin 4-3-5 have the same structure. Taking the second spring pin 2-3 as an example, the second spring pin 2-3 includes a thrust spring 2-3-1, a locking pin 2-3-2 and a sleeve 2-3-3. The locking pin 2-3-2 is a T-shaped structure with a long and short axis. The short axis of the locking pin 2-3-2 is welded to one end of the long axis. A handle is provided at one end of the locking pin 2-3-2, and the handle is perpendicular to the locking pin 2-3-2. The locking pin 2-3-2 is stepped, and a ring flange 2-3-4 is provided on the side of the locking pin 2-3-2 away from the handle. The sleeve 2-3-3 is open at one end and provided with a closed cover at the other end. A non-circular long hole is provided on the closed cover. A non-circular segment and a cylindrical segment whose cross section corresponds to the non-circular hole are provided on the locking pin shaft. The cylindrical segment can rotate in the non-circular hole. The non-circular hole in the present application is an elongated hole 2-3-5, and the non-circular segment is an elongated segment 2-3-6 whose cross section corresponds to the elongated hole 2-3-5. The diameter of the cylindrical segment 2-3-7 is the same as the width of the elongated hole 2-3-5, so that the cylindrical segment 2-3-7 can rotate freely in the elongated hole 2-3-5. The sleeve 2-3-3 is sleeved on the outside of the thrust spring 2-3-1, and the two ends of the thrust spring 2-3-1 are respectively in contact with the annular flange 2-3-4 and the closed cover. During assembly, the thrust spring 2-3-1 and the sleeve 2-3-3 are sequentially mounted on the outer side of the long round end of the long axis of the locking pin 2-3-2, and then a handle is welded to the end of the locking pin 2-3-1.

[0078] The second spring pin 2 - 3 has two states, namely a locked state and an unlocked state.

[0079] When in the locked state, the second spring pin 2-3 is acted upon by the thrust spring 2-3-1, so that the end of the second spring pin 2-3 abuts against the second locking hole. The state at this time is the locked state, thereby limiting the rotation of the worm hand wheel 4-8-4.

[0080] When in the unlocked state, pull the handle, the locking pin 2-3-2 slides in the long hole 2-3-5 (the long section 2-3-6 slides in the long hole 2-3-5), when the cylindrical section 2-3-7 slides into the long hole 2-3-5, then turn the handle so that the long section 2-3-6 and the long hole 2-3-5 are interlaced, release the handle, at this time the closing cover abuts against the long section 2-3-6 to limit the position, at this time the end of the locking pin 2-3-2 is separated from the second locking hole. It is the unlocked state, at this time the mandrel can rotate freely, thereby driving the reducer 2 to rotate, and realizing the lifting and lowering of the oil barrel 5.
