Description

Technical Field

[0001] This utility model relates to the field of vacuum quenching heat treatment technology, and in particular to a vacuum oil furnace refueling device. Background Technology

[0002] Vacuum oil furnaces are widely used in vacuum quenching heat treatment. They achieve efficient and stable heat transfer by heating heat-conducting oil in a closed environment, offering advantages such as uniform heating, high temperature control precision, and good safety. In industries such as chemical, plastics, rubber, and energy, vacuum oil furnaces serve as critical heat source equipment, and their operational efficiency and safety have a decisive impact on the stability and energy consumption of the entire production system. The refueling device, as a crucial component of the vacuum oil furnace system, directly affects the convenience, safety, and overall stability of the refueling process through its structural design and functional configuration.

[0003] According to utility model patent CN 208887112 U, a rapid refueling device for an oil-conducting furnace includes a mounting base plate, movable wheels, an oil storage tank, an oil pump, an oil guide pipe, a non-slip handle, an oil outlet pipe structure, an adjustable mounting pusher structure, an oil outlet pipe wiping sleeve structure, an oil inlet pipe, a protective cover, a connecting rope, and an observation window. This device, through the movable wheels and adjustable mounting pusher, provides good mobility and adaptability. Simultaneously, the wiping sleeve, made of a sponge sleeve with a wall thickness of two to three centimeters, can clean the outside of the oil outlet pipe before refueling, reducing the risk of impurities entering the system.

[0004] Despite these improvements in the mobility and cleaning capabilities of the refueling device—for example, by using bolts or nylon ropes to connect to external mobile devices, enhancing portability, and by employing a sponge-material wiping sleeve for easy cleaning of dust from the outside of the refueling pipe—significant structural defects remain in practical use. Specifically, the device only has a moving mechanism for flexible tank movement, lacking an effective positioning structure. When encountering sloping ground or wind interference, the moving base and tank may slip unexpectedly, posing a serious safety hazard. Furthermore, the lack of positioning and securing measures also affects the stability of the refueling process, easily leading to unstable connections in the oil pipe, leaks, or even splashing, further threatening the safety of operators and the normal operation of the equipment.

[0005] Therefore, in response to the shortcomings of existing technologies, we urgently need a vacuum oil furnace refueling device. This new device should retain the original convenient refueling and cleaning functions while adding a reliable positioning and support structure to ensure stable operation under various complex terrain conditions, effectively prevent slippage and overturning accidents, thereby improving the safety and efficiency of the refueling process and providing a solid guarantee for the efficient and safe operation of industrial heating systems. Utility Model Content

[0006] The purpose of this utility model is to provide a vacuum oil furnace refueling device, which solves the problem that in the prior art, only the moving mechanism can realize the flexible movement of the oil tank, but no effective positioning structure is set. When encountering inclined ground or wind interference, the moving base and the oil storage tank may slide unexpectedly, thus causing serious safety hazards.

[0007] To achieve the above objectives, this utility model provides a vacuum oil furnace refueling device, comprising a movable base, an oil storage tank, and a refueling nozzle;

[0008] Both ends of the movable base are detachably connected to mounting plates. The bottom of the mounting plate is provided with a support plate, and the top is provided with a pushing structure. The output end of the pushing structure is connected to the top of the support plate.

[0009] Side plates are connected to the center of both sides of the movable base. A contact plate is provided at the bottom of the side plate, and the contact plate is connected to the bottom of the side plate through a vertical adjustment structure.

[0010] The mounting plate is made of metal, and a positioning frame is fixedly connected to one side of the mounting plate. The positioning frame is bolted to the side wall of the movable base.

[0011] The support plate has guide rods fixedly connected to both ends, and the sidewalls of the guide rods are slidably connected to the sidewalls of the mounting plate.

[0012] The bottom center of the movable base is connected to a bottom plate, and both ends of the bottom plate are connected to the bottom of the adjacent positioning frame through several connecting screws. Both sides of the bottom plate are fixedly connected to the ends of the side plates.

[0013] The vertical adjustment structure includes an adjustment screw with one end threaded through the side plate, and one end of the adjustment screw is rotatably connected to the top of the contact plate.

[0014] The top end of the adjusting screw is fixedly connected to a rotating handle, and the outer ring of the rotating handle is fitted with a rubber sleeve.

[0015] This utility model discloses a vacuum oil furnace refueling device. By setting detachable mounting plates at both ends of the movable base and configuring a support plate at its bottom, the support range of the refueling device is expanded, effectively improving the stability of the equipment under complex terrain conditions. Secondly, the linkage design of the pushing structure and the support plate allows the operator to complete the initial support preparation during the pushing process, improving work efficiency. Thirdly, the side plate and the contact plate are connected by a vertical adjustment structure, which can flexibly adjust the height according to the flatness of the ground, further enhancing the adaptability and anti-slip performance of the equipment. In addition, the contact plate not only plays an auxiliary support role, but also forms a physical limit during the refueling process to prevent the oil tank and the entire device from being accidentally displaced. In summary, this refueling device, while retaining the original convenient mobility function, adds a positioning and support structure, significantly improving the safety, stability and operational efficiency of the refueling process. It solves the safety hazards such as slippage and overturning caused by the lack of positioning and fixing measures in the prior art, providing solid technical support for the efficient and safe operation of industrial heating systems.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a vacuum oil furnace refueling device according to this embodiment includes a movable base 1, an oil storage tank 4, and a refueling gun 5; both ends of the movable base 1 are detachably connected to mounting plates 3, the bottom of the mounting plate 3 is provided with a support plate 2, and the top is provided with a pushing structure, the output end of the pushing structure is connected to the top of the support plate 2; side plates 7 are connected to the center of both sides of the movable base 1, and the bottom of the side plates 7 is provided with contact plates 14, which are connected to the bottom of the side plates 7 through a vertical adjustment structure.

[0026] First, the mobile base 1 is assembled using mounting plates 3 at both ends, and a support plate 2 is connected to the bottom of the mounting plates 3 to enhance the overall support area and stability of the equipment. The operator pushes the support plate 2 using a pushing mechanism. After stopping at the refueling location, the operator pushes the support plate 2 again to lift the entire mobile base 1 and the oil tank 4, raising the wheels away from the ground. Then, the vertical adjustment structure is adjusted according to the ground conditions to ensure the contact plate 14 is in full contact with the ground and bears part of the support force, preventing the refueling device from slipping on slopes or under wind conditions. Side plates 7 are fixed to the center of both sides of the mobile base 1 to support the contact plate 14 and its adjustment structure. When the refueling nozzle 5 begins operation, the oil tank 4 is stably placed on the mobile base 1, maintaining stability with the double limiting effect of the support plate 2 and the contact plate 14, preventing loosening or splashing of the oil guide pipe due to external interference. The entire refueling process is completed under the protection of a stable support system, ensuring the safety and continuity of the refueling operation.

[0027] Example 2

[0028] Please see Figure 1-5As shown in this embodiment, a vacuum oil furnace refueling device has a mounting plate 3 made of metal. A positioning frame 10 is fixedly connected to one side of the mounting plate 3. The positioning frame 10 is bolted to the side wall of the movable base 1. The pushing structure includes a pushing cylinder 9. The output end of the pushing cylinder 9 is connected to the top of the support plate 2. Specifically, by using a metal mounting plate 3 and fixing a positioning frame 10 to one side, and bolting the positioning frame 10 to the side wall of the movable base 1, the positioning frame 10 enhances the connection strength between the mounting plate 3 and the movable base 1 during assembly. The working process involves firmly connecting the mounting plate 3 to the movable base 1 with bolts, thereby increasing the stability and durability of the entire device structure and ensuring that it will not loosen due to vibration or external force during handling and use.

[0029] A bottom plate 6 is connected to the center of the bottom of the movable base 1. Both ends of the bottom plate 6 are connected to the bottom of the adjacent positioning frame 10 through several connecting screws 11. Both sides of the bottom plate 6 are fixedly connected to the ends of the side plate 7. A fixing plate 12 connected to the side wall of the movable base 1 is fixedly connected to the top side of the side plate 7. Specifically, the bottom plate 6 is connected to the center of the bottom of the movable base 1. Both ends of the bottom plate 6 are connected to the bottom of the adjacent positioning frame 10 through several connecting screws 11. Both sides of the bottom plate 6 are fixedly connected to the ends of the side plate 7. When the support plate 2 is lifted so that the movable wheels leave the ground, the bottom plate 6 and the side plate 7 share the support load. The working process is that when the support plate 2 is lifted, the bottom plate 6 and the side plate 7 form a stable support frame, which achieves the effect of dispersing and evenly distributing the weight, increasing the load-bearing capacity and stability of the entire device, and reducing the risk of local overload.

[0030] Example 3

[0031] Please see Figure 1-5 As shown in this embodiment, a vacuum oil furnace refueling device has guide rods 8 fixedly connected to both ends of the support plate 2. The side walls of the guide rods 8 are slidably connected to the side walls of the mounting plate 3. Specifically, by fixing guide rods 8 to both ends of the support plate 2 and slidably connecting the side walls of the guide rods 8 to the side walls of the mounting plate 3, when the support plate 2 is pushed, the guide rods 8 slide along the side walls of the mounting plate 3. The working process is that when the operator lifts the support plate 2 by pushing the structure, the guide rods 8 provide a smooth guiding effect, which ensures the straightness and stability of the support plate 2 during the up and down movement, prevents deviation or jamming, and enhances the operation convenience and safety of the equipment.

[0032] The vertical adjustment structure includes an adjusting screw 15 with one end threaded through the side plate 7. One end of the adjusting screw 15 is rotatably connected to the top of the contact plate 14. Specifically, by setting up the adjusting screw 15 with one end threaded through the side plate 7 and one end rotatably connected to the top of the contact plate 14, the adjusting screw 15 is rotated to change its extension length when adjusting the height of the contact plate 14. The working process is to rotate the adjusting screw 15 according to the flatness of the ground, so that it drives the contact plate 14 to move up and down until it contacts the ground, thereby achieving the purpose of precisely adjusting the position of the contact plate 14, ensuring that the equipment can remain stable on uneven ground, and improving its ability to adapt to different terrains.

[0033] A rotating handle 13 is fixedly connected to the top end of the adjusting screw 15. A rubber sleeve is fitted around the outer ring of the rotating handle 13. Specifically, by fixing the rotating handle 13 to the top end of the adjusting screw 15 and fitting a rubber sleeve around the outer ring of the rotating handle 13, the adjusting screw 15 is manually adjusted by rotating the rotating handle 13 with the rubber sleeve. The workflow is to hold the rotating handle 13 and apply torque to rotate the adjusting screw 15. This achieves the effect of facilitating fine-tuning by the operator and preventing slippage, avoiding inconvenience or injury caused by slipping hands, while improving the comfort and efficiency of operation.

[0034] The complete workflow of the vacuum oil heater refueling device provided by this utility model is as follows: First, the operator assembles the mobile base 1 using mounting plates 3 at both ends. The mounting plates 3 are made of metal and have a positioning frame 10 fixedly connected to one side. They are then bolted to the side wall of the mobile base 1 to enhance the overall structural strength. Next, a support plate 2 is connected to the bottom of the mounting plate 3. Guide rods 8 are provided at both ends of the support plate 2. These guide rods 8 slide against the side wall of the mounting plate 3 and move up and down under the action of the pushing structure. When the refueling device moves to the target position, the operator pushes the support plate 2 upward using the pushing structure, lifting the entire mobile base 1 and the oil tank 4, thereby removing the moving wheels from the ground. Simultaneously... The mobile base 1 has a bottom plate 6 at its center, which is connected to the bottom of the positioning frame 10 at both ends by connecting screws 11 and fixedly connected to the ends of the side plates 7 on both sides to form a stable load-bearing frame. The bottom of the side plate 7 is connected to the contact plate 14 through a vertical adjustment structure. The vertical adjustment structure includes an adjustment screw 15. One end of the adjustment screw 15 is threaded through the side plate 7, and the other end is rotatably connected to the top of the contact plate 14. The operator can rotate the adjustment screw 15 according to the flatness of the ground to make it move the contact plate 14 up and down and keep it close to the ground, thereby achieving auxiliary support and anti-slip limit for the entire device. The top of the adjustment screw 15 is fixedly connected to a rotating handle 13, which has a rubber sleeve on its outer ring for easy manual adjustment and anti-slip, improving operating comfort and safety.

[0035] This structural design brings significant benefits. First, the mounting plate 3 and positioning frame 10 enhance the overall rigidity of the refueling device, ensuring it won't loosen due to vibration or impact under complex working conditions, thus improving the equipment's durability and stability. Second, the sliding fit between the guide rod 8 and the mounting plate 3 ensures the smooth operation of the support plate 2 during lifting, preventing jamming or offset, and improving operational safety and reliability. Third, the bottom plate 6, connecting screw 11, and side plate 7 together form a load-bearing system, allowing the device to distribute weight evenly under support, avoiding localized overload that could damage the structure and extending its service life. Furthermore, the vertical structure formed by the contact plate 14 and adjusting screw 15... The direct adjustment structure gives the device excellent terrain adaptability, allowing it to operate stably on uneven ground or slopes, effectively preventing slippage or overturning and ensuring safety during the refueling process. Finally, the rubber-sleeved rotating handle enhances the convenience and comfort of manual adjustment, reducing operator fatigue and improving work efficiency. In summary, this refueling device not only retains the convenience of traditional mobile refueling equipment but also significantly improves its stability and safety in various complex environments by adding a multi-stage support and adjustment structure. It solves the safety hazards of slippage and overturning caused by the lack of positioning and fixing measures in existing technologies, providing a solid technical guarantee for the efficient and safe operation of industrial heating systems.
