Description
Technical Field
[0001] The utility model relates to the technical field of oil nozzles and gas nozzles, in particular to an oil-gas integrated nozzle. Background Art
[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching speeds and transmitting torques between a prime mover and a working machine or an actuator, and is widely used in modern machinery.
[0003] When the speed reducer lacks oil inside, it will cause direct contact between components, increase friction, and lead to increased wear; before the speed reducer leaves the factory or after maintenance, it is necessary to perform a airtightness test on the speed reducer. After the airtightness test is qualified, a specified volume of lubricating oil is added to the inside of the speed reducer. However, in the prior art, the airtightness test and the refueling operation of the speed reducer are usually carried out separately. After the airtightness test is qualified, the speed reducer needs to be moved to the refueling place for refueling, and its efficiency is low. Based on this, an oil-gas integrated nozzle is designed. Content of the Utility Model
[0004] In order to overcome at least one of the above-mentioned defects in the prior art, the utility model provides an oil-gas integrated nozzle. By integrating the fuel filling port and the gas filling port on an oil-gas nozzle body, continuous operation of airtightness detection and fuel filling is realized at the same station, the operation process is simplified, and the work efficiency is improved.
[0005] The technical solution adopted by the utility model to solve its problems is as follows:
[0006] An oil-gas integrated nozzle, comprising: an oil-gas nozzle body, the inside of the oil-gas nozzle body is hollow to form an accommodation space, and the oil-gas nozzle body is also provided with a fuel filling port and a gas filling port; wherein, the accommodation space includes a fuel filling space and a gas filling space, the fuel filling port is communicated with the fuel filling space to form a fuel filling channel, and the gas filling port forms a gas filling channel with the gas filling space; it also includes an oil pipeline, the oil pipeline is communicated with the fuel filling channel, and a first gas channel for gas to pass through is left between the oil pipeline and the gas filling channel.
[0007] By adopting the above solution, the design of the oil-gas integrated nozzle realizes the continuous operation of first performing airtightness detection and then refueling on the same work station without moving the speed reducer, thereby significantly improving the work efficiency, simplifying the operation process, reducing the operation difficulty, enabling the continuous operation of airtightness detection and refueling on one workpiece, reducing the time for equipment movement and waiting, thus saving labor and time costs; moreover, the integrated design also reduces the number of components, lowering the manufacturing and production costs; and the gas at the gas filling port can enter the speed reducer through the gas filling channel, the first gas channel and the second gas channel, and the oil at the oil filling port can enter the speed reducer through the oil pipeline.
[0008] Furthermore, the oil-gas nozzle body has a connection area, the connection area has an opening and is communicated with the accommodation space, and at least part of the oil pipeline is exposed outside the opening of the connection area.
[0009] By adopting the above solution, the connection area with an open design and the oil pipeline exposed outside can be applicable to the refueling operations of various speed reducers, facilitating the insertion of the oil pipeline into the oil filling hole of the speed reducer to meet the working requirements in different situations.
[0010] Furthermore, a sealing soft pad is arranged in the connection area, and an avoidance hole for avoiding the oil pipeline is opened on the sealing soft pad.
[0011] By adopting the above solution, the sealing soft pad provides an additional sealing layer to prevent gas or oil from leaking in the connection area, and the sealing soft pad can also play a role in protecting the oil pipeline, and the sealing soft pad also has the necessary sealing effect when detecting airtightness.
[0012] Furthermore, a second gas channel for gas to pass through is left between the inner wall of the avoidance hole and the oil pipeline, and the first gas channel is communicated with the second gas channel.
[0013] By adopting the above solution, the gas at the gas filling port can flow into the speed reducer through the first gas channel and the second gas channel.
[0014] Furthermore, the cross-sectional area of the connection area is larger than the cross-sectional areas of the oil filling space and the gas filling space.
[0015] By adopting the above solution, the larger cross-sectional area of the connection area helps to reduce the resistance when the fluid passes through, enabling the gas and oil to pass through more smoothly; and it is convenient to reserve the area of the second gas channel for the gas to flow through the second gas channel.
[0016] Furthermore, the cross-sectional area of the oil filling space is smaller than the cross-sectional area of the gas filling space.
[0017] By adopting the above solution, the areas of the refueling space and the gas filling space are set to be inconsistent, so as to leave out the area of the first gas passage and facilitate the flow of gas through the first gas passage. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the specification of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.
[0026] Referring to Figure 2 and Figure 3 , this utility model discloses an oil-gas integrated nozzle, which includes an oil-gas nozzle body 1 and an oil pipeline 2. The interior of the oil-gas nozzle body 1 is hollow to form a receiving space 11. The oil-gas nozzle body 1 is further provided with a fuel filling port 12 and a gas filling port 13. Both the fuel filling port 12 and the gas filling port 13 communicate with the receiving space 11. The receiving space 11 includes a fuel filling space 111 and a gas filling space 112. Specifically, the fuel filling port 12 communicates with the fuel filling space 111, the gas filling port 13 communicates with the gas filling space 112. The fuel filling port 12 and the fuel filling space 111 communicate to form a fuel filling channel 121, the gas filling port 13 and the gas filling space 112 form a gas filling channel 131. The oil pipeline 2 communicates with the fuel filling channel 121, and a first gas channel 21 for gas to pass through is left between the oil pipeline 2 and the gas filling channel 131.
[0027] Specifically, during use, the fuel filling port 12 is connected to an external fuel tank (not shown) through a fuel filling pipeline (not shown) connected between the fuel filling port 12 and the fuel tank (not shown) to complete the operation of transporting the fuel in the fuel tank (not shown) to the fuel filling port 12. The gas filling port 13 is also connected to an external gas storage tank (not shown) through a gas filling pipeline (not shown) connected between the gas filling port 13 and the gas storage tank (not shown) to complete the operation of transporting the gas in the gas storage tank (not shown) to the gas filling port 13.
[0028] Such a design realizes the continuous operation of first performing airtightness detection and then fuel filling at the same station without moving the speed reducer, thus significantly improving the work efficiency, simplifying the operation process, reducing the operation difficulty, enabling gas filling and fuel filling, reducing the time for equipment movement and waiting, thereby saving labor and time costs; moreover, the integrated design also reduces the number of components, reducing the manufacturing and production costs; and the gas at the gas filling port 13 can enter the speed reducer through the gas filling channel 131, the first gas channel 21 and the second gas channel 32, and the fuel at the fuel filling port 12 can enter the speed reducer through the fuel filling channel 121 and the oil pipeline 2.
[0029] Referring to Figure 1 and Figure 2, in this embodiment, the gas filling port 13 and the fuel filling port 12 are arranged on the same side, and the fuel filling port 12 is arranged above the gas filling port 13. Moreover, in this embodiment, both the gas filling port 13 and the fuel filling port 12 are horizontally arranged. It should be noted that in other embodiments, the fuel filling port 12 and the gas filling port 13 can be arranged on different sides, and the position of the fuel filling port 12 can also be arranged below the gas filling port 13. The fuel filling port 12 can also be arranged on different sides at the same height as the gas filling port 13. Moreover, the gas filling port 13 and the fuel filling port 12 can also be inclined. Among them, it should be noted that in this embodiment, the oil pipeline 2 will occupy the space of the gas filling space 112 for the installation of the oil pipeline 2.
[0030] Refer to Figure 2 As shown, in this embodiment, the oil and gas nozzle body 1 has a connection area 14. The connection area 14 has an opening 141 and is communicated with the accommodation space 11. At least part of the oil pipeline 2 is exposed outside the opening 141 of the connection area 14. The connection area 14 designed with the opening 141 and the exposed oil pipeline 2 can be applicable to the fuel filling operations of various speed reducers, facilitating the input pipeline to be inserted into the fuel filling hole of the speed reducer to meet the working requirements in different situations.
[0031] Among them, in this embodiment, the cross-sectional area of the connection area 14 is larger than the cross-sectional areas of the fuel filling space 111 and the gas filling space 112. The larger cross-sectional area of the connection area 14 helps to reduce the resistance when the fluid passes through, making the gas and oil pass more smoothly. Moreover, it is convenient to reserve the area of the second gas channel 32 for the gas to flow through the second gas channel 32.
[0032] Among them, in this embodiment, the cross-sectional area of the fuel filling space 111 is smaller than the cross-sectional area of the gas filling space 112. By setting the areas of the fuel filling space 111 and the gas filling space 112 to be inconsistent, the area of the first gas channel 21 can be reserved for the gas to flow through the first gas channel 21. Specifically, no matter when the fuel filling port 12 is above the gas filling port 13, the fuel filling port 12 is below the gas filling port 13, or the fuel filling port 12 and the gas filling port 13 are at the same height, the cross-sectional area of the fuel filling space 111 is smaller than the cross-sectional area of the gas filling space 112 to reserve an area for the gas to pass through.
[0033] In this embodiment, specifically, a sealing soft pad 3 is provided in the connection area 14. An avoidance hole 31 for avoiding the oil pipeline is formed in the sealing soft pad 3. The sealing soft pad 3 provides an additional sealing layer to prevent oil or gas from leaking in the connection area 14. Moreover, the sealing soft pad 3 can protect the oil pipeline and also has the necessary sealing effect for detecting air tightness. It should be noted that at least part of the oil pipeline 2 is not only exposed outside the opening 141 of the connection area 14, but also at least part of it is exposed outside the sealing soft pad 3, which is convenient for the oil pipeline 2 to be directly docked with the oil filling hole of the speed reducer to realize the oil filling operation. A gap is left between the bottom of the sealing soft pad 3 and the oil pipeline 2 to allow gas to pass through.
[0034] Wherein, a second gas passage 32 for gas to pass through is left between the inner wall of the avoidance hole 31 and the oil pipeline, and the first gas passage 21 and the second gas passage 32 are communicated. The gas at the gas filling port 13 can flow into the speed reducer through the first gas passage 21 and the second gas passage 32.
[0035] In this embodiment, a connection area 4 is further formed on the oil and gas nozzle body 1. Internal threads 41 are provided on the inner wall of the connection area 4 to facilitate connection with other devices and achieve the fixing effect of the oil and gas nozzle body 1. In other embodiments, the connection area 4 can also be provided with an adsorbent to achieve the adsorption connection with other devices and also realize the fixing effect of the oil and gas nozzle; among them, it should be noted that in additional other embodiments, a connection method with other devices that is equivalent or has a better effect can also be used to achieve the fixing effect, which is not specifically limited herein.
[0036] The working principle and steps of the present utility model are as follows: The gas storage tank supplies gas to the gas filling port 13. The gas passes through the gas filling channel 131 from the gas filling port 13, then through the first gas passage 21 and the second gas passage 32 and enters the speed reducer to perform the air tightness detection on the speed reducer. After the air tightness detection is qualified, the oil tank can further supply oil to the oil filling port 12. The oil passes through the oil filling channel 121 from the oil filling port 12 and then flows into the speed reducer through the oil pipeline 2 for oil filling, realizing continuous air tightness detection and oil filling operations at the same station, with simple operation and high efficiency.
[0037] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
