Description

Technical Field

[0001] This utility model relates to the technical field of material handling equipment, specifically a material handling machine chain oil tank refueling device. Background Technology

[0002] Slag reclaiming and processing utilize large, heavy-duty equipment. Ensuring proper operation requires oil lubrication of the machine chains. In the design of slag reclaimer chain lubrication tanks, to facilitate operation and maintenance, the tanks are typically placed at a high position, reaching a height of 5 meters. This design ensures that the oil can flow freely to the chain under gravity for effective lubrication. However, this location brings several inconveniences and risks. First, because the tank is located at a high position and there is a lack of reliable stairs or other access facilities, operators usually need to climb the reclaimer's casing, which not only increases the difficulty of operation but also poses significant safety hazards. Furthermore, this method of operation is inefficient, affecting the overall construction progress and significantly increasing maintenance costs.

[0003] While devices exist to improve fuel tank refueling convenience, most require significant modifications to the existing tank structure to accommodate the new filling system. This not only increases modification costs but also raises construction complexity, impacting efficiency. More importantly, existing filling systems lack broad adaptability and cannot be directly applied to existing tank structures, limiting their widespread use and making it difficult to meet the specific needs of different workplaces.

[0004] Therefore, it is necessary to provide a refueling device for the chain tank of a material handling machine that can perform convenient, efficient, and safe refueling operations without changing the original tank structure. Utility Model Content

[0005] This utility model proposes a refueling device for the chain oil tank of a material handling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A refueling device for a chain oil tank of a material reclaimer includes an oil tank on the material reclaimer. The top of the oil tank has an oil inlet, and a sealing cover is installed on the oil inlet. A buoy detection structure, a buzzer, and an oil injection pipe are installed on the sealing cover. The buoy detection structure has a float that extends into the oil tank. The buzzer is electrically connected to the buoy detection structure. The other end of the oil injection pipe is connected to an original oil drum. A folding plate is provided inside the oil tank, and both ends of the folding plate are connected to fixing ropes. The upper ends of the two fixing ropes pass through the sealing cover and are connected to each other. A refueling pump is installed on the oil injection pipe.

[0008] Preferably, the buoy detection structure includes a transparent square tube and a detection rod. The sealing cover has a square opening, the transparent square tube is fixed to the square opening, the lower end of the detection rod is connected to the float, and the upper end of the detection rod extends through the square opening into the transparent square tube. The detection rod and the float, as well as the transparent square tube and the oil tank, are connected and fixed by adhesive or bolts, facilitating replacement, storage, and transportation.

[0009] Preferably, a switch one is located at the top of the transparent square tube, a switch two is located at the bottom of the transparent square tube, and a contact plate is located at the top of the detection rod. The contact plate is situated between switch one and switch two, and switch one and switch two are electrically connected to a buzzer. As the detection rod moves up and down, the contact plate contacts switch one and switch two, thereby triggering the buzzer to remind the operator whether the fuel tank is low or full.

[0010] Preferably, the outer side of the transparent square tube is provided with a scale along the length of the transparent square tube. The sum of the lengths of the float and the detection rod, as well as the length of the transparent square tube, are matched with the height inside the oil tank. The lengths of the detection rod and the transparent square tube can be changed according to the height inside the oil tank.

[0011] Preferably, the sealing cover has two through holes, and the two fixing ropes pass through the corresponding holes on their respective sides, and the two fixing ropes are connected and fixed by a rope buckle. The rope buckle can be a fastening buckle, elastic buckle, etc., all of which are existing mature technologies and are not limited to here.

[0012] Preferably, the folding plate comprises two steel plates connected by a hinge, and two fixing ropes are connected to the two steel plates one-to-one. The sum of the lengths of the two steel plates must be greater than the diameter of the fuel tank inlet. Steel plates of different lengths can be replaced according to the diameter of the fuel tank inlet to adapt to fuel tanks of different sizes.

[0013] Preferably, a manual valve and a movable joint are also installed on the oil injection pipe between the fuel pump and the fuel tank. The movable joint is an existing pipe joint and is not limited to this one. The fuel pump injects lubricating oil from the crude oil drum into the fuel tank. The manual valve can be manually opened or closed to allow flow through the oil injection pipe. The movable joint improves the flexibility of the oil injection pipe connection and facilitates pipeline layout in different locations.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention enables real-time monitoring and early warning of fuel level by installing a sealing cap on the top of the fuel tank and incorporating a float detection structure, buzzer, and fuel injection pipe on the cap. When the fuel tank is low on fuel, the float sinks with the level of lubricating oil in the tank, the contact plate of the detection rod contacts the second switch, triggering the buzzer to sound an alarm to remind the operator that the fuel tank is low on fuel. When the fuel tank is full, the float rises with the level of lubricating oil, the contact plate of the detection rod contacts the first switch, and the buzzer sounds an alarm to remind the operator that the fuel tank is full. Furthermore, a fuel pump is installed on the fuel injection pipe, allowing for quick and accurate refueling of the fuel tank using lubricating oil supplied from the original oil drum. This avoids the traditional high-altitude climbing operation method, improving operational safety and efficiency, and reducing operating costs. Additionally, a folding clamp inside the fuel tank is connected to the sealing cap via a fixing rope. By changing the length of the folding clamp, it can be adapted to fuel tanks of different sizes, demonstrating strong adaptability. This invention effectively reduces modification costs and construction complexity without altering the original fuel tank structure, improves maintenance efficiency, and ensures the safety and reliability of equipment operation and maintenance.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3A refueling device for a chain oil tank of a material handling machine includes an oil tank 1 on the material handling machine. The top of the oil tank 1 is provided with an oil inlet 2. A sealing cover 4 is installed on the oil inlet 2. A buoy detection structure 3, a buzzer 5, and an oil injection pipe 6 are installed on the sealing cover 4. The buoy detection structure 3 is equipped with a float ball 11 that extends into the oil tank 1. The buzzer 5 is electrically connected to the buoy detection structure 3. The other end of the oil injection pipe 6 is connected to an original oil drum 10. A folding plate 15 is provided inside the oil tank 1. Both ends of the folding plate 15 are connected to fixing ropes 16. The upper ends of the two fixing ropes 16 pass through the sealing cover 4 and are connected to each other. A refueling pump 9 is installed on the oil injection pipe 6.

[0022] The buoy detection structure 3 includes a transparent square tube 13 and a detection rod 12. The sealing cover 4 has a square opening 14, and the transparent square tube 13 is fixed to the square opening 14. The lower end of the detection rod 12 is connected to the float 11, and the upper end of the detection rod 12 passes through the square opening 14 and extends into the transparent square tube 13. The detection rod 12 and the float 11, and the transparent square tube 13 and the oil tank 1 are all connected and fixed by adhesive or bolts, facilitating replacement, storage, and transportation.

[0023] A switch 20 is located at the top of the transparent square tube 13, and a switch 21 is located at the bottom of the transparent square tube 13. A contact plate 19 is located at the top of the detection rod 12, between the switch 20 and the switch 21. The switch 20 and the switch 21 are electrically connected to the buzzer 5. The contact plate 19 contacts the switch 20 and the switch 21 as the detection rod 12 moves up and down, thereby triggering the buzzer 5 to remind the operator whether the fuel tank 1 is low or full.

[0024] The outer side of the transparent square tube 13 is provided with a scale along the length of the transparent square tube 13. The sum of the lengths of the float 11 and the detection rod 12, as well as the length of the transparent square tube 13, are matched with the height inside the oil tank 1. The lengths of the detection rod 12 and the transparent square tube 13 can be changed according to the height inside the oil tank 1.

[0025] The sealing cover 4 has two through holes 18, and the two fixing ropes 16 pass through the corresponding through holes 18 on their respective sides. The two fixing ropes 16 are connected and fixed by a rope buckle 17. The rope buckle 17 can be a fixing buckle, a tension buckle, etc., which are all existing mature technologies and are not limited to here.

[0026] The folding plate 15 includes two steel plates connected by a hinge, and the two fixing ropes 16 are connected to the two steel plates one-to-one. The sum of the lengths of the two steel plates must be greater than the diameter of the oil inlet 2 of the oil tank 1. Steel plates of different lengths can be replaced according to the diameter of the oil inlet 2 of different oil tanks 1 for installation, so as to adapt to the use of oil tanks 1 of different sizes.

[0027] A manual valve 7 and a movable joint 8 are also installed on the oil injection pipe 6 between the refueling pump 9 and the oil tank 1. The movable joint 8 is an existing pipe joint and is not limited to this one. The lubricating oil in the crude oil drum 10 is injected into the oil tank 1 by the refueling pump 9. The manual valve 7 can be manually opened or closed to allow the flow of the oil injection pipe 6. The movable joint 8 improves the flexibility of the connection of the oil injection pipe 6 and facilitates the pipeline layout in different locations.

[0028] In use, the float 11, along with the detection rod 12, is placed into the oil tank 1. The sealing cap 4 is installed at the oil inlet 2. The hinge side of the folding plate 15 faces upward. The folding plate 15 is folded when entering the oil inlet 2 due to the hinge folding. When the fixing rope 16 is pulled in and fixed, the two ends of the folding plate 15 are locked inside the oil inlet 2, preventing it from folding and causing the sealing cap 4 to be tightly pressed against the oil inlet 2. As the lubricating oil in the oil tank 1 is consumed, the float 11 sinks as the lubricating oil level drops, causing the detection rod 12 to descend until the contact plate 19 of the detection rod 12 contacts the switch 21, triggering the buzzer 5 to warn the worker of low oil levels. The worker can use the oil pump 9 to transfer the lubricating oil from the crude oil drum 10 to the oil tank 1 through the oil filling pipe 6. The float 11 inside the oil tank 1 moves upward as the lubricating oil level rises until the contact plate 19 contacts the switch 20, triggering the buzzer 5 to remind the worker that the oil tank 1 is full. Then, the refueling pump 9 is stopped and the manual valve 7 is closed, completing the refueling process for the oil tank 1. This invention effectively reduces modification costs and construction complexity without altering the original structure of the oil tank 1, improves maintenance efficiency, and ensures the safety and reliability of equipment operation and maintenance.
