[0037] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0038] Reference Figures 1 to 4 As shown, this utility model provides a turnout rotator oil injection device.

[0039] ReferenceFigure 1 As shown, the turnout rotator oil injection device includes a housing 100, an oil injection pipeline 200, and a container 300.

[0040] The housing 100 has an inner cavity 110 inside, and the side wall of the housing 100 is recessed into the inner cavity 110, so that the side wall of the housing 100 forms an installation cavity 120 for accommodating the container 300.

[0041] The bottom of the housing 100 is provided with a connecting pipe that extends downwards. The outer wall of the connecting pipe is provided with external threads, which are used to connect to the oil tank threaded hole of the turnout turner.

[0042] The oil filling line 200 is installed in the inner cavity 110. The two ends of the oil filling line 200 are respectively provided with a connector 210 and an oil filling hole 220. The connector 210 is installed in the mounting cavity 120, and the oil filling hole 220 is installed in the connecting pipe at the bottom of the housing 100. The oil filling line 200 delivers the liquid from the connector 210 to the oil filling hole 220.

[0043] The container 300 is detachably disposed in the mounting cavity 120. For example, the container 300 is placed in the mounting cavity 120 and fixed by clamping the container 300 with the inner wall of the mounting cavity 120; or, the container 300 is cylindrical, with external threads on the bottom of its outer side wall, the shape of the mounting cavity 120 matches the shape of the container 300, and internal threads are provided on the bottom of its inner side wall, so that the container 300 is threadedly connected to the mounting cavity 120; or, the outer side wall of the container 300 has a snap-fit, and the inner side wall of the mounting cavity 120 has a snap fastener, so that the container 300 is inserted into the mounting cavity 120, and the snap fastener and snap-fit ​​engage to detachably connect the container 300 to the mounting cavity 120.

[0044] The bottom of the container 300 is provided with an interface 310, the position of which corresponds to the position of the connector 210 in the mounting cavity 120. After the container 300 is placed in the mounting cavity 120, the interface 310 is directly opposite the connector 210. A first one-way valve 320 is provided in the interface 310. When the inside of the container 300 is filled with aviation oil, the aviation oil will push the first one-way valve 320 at the bottom to move outward of the container 300, causing the first one-way valve 320 to close the interface 310.

[0045] The top of the container 300 is provided with an opening 330 and a top cover 340. The top cover 340 is used to detachably seal the opening 330. A second one-way valve 350 is provided in the middle of the top cover 340. The conduction direction of the second one-way valve 350 is from the outside to the inside of the container 300.

[0046] When the container 300 is placed in the mounting cavity 120, the connector 210 is inserted into the interface 310. The connector 210 will push the first one-way valve 320 in the interface 310 to move into the interior of the container 300, so that the connector 210 of the oil injection line 200 is connected to the interface 310 of the container 300.

[0047] It is understood that the first one-way valve 320 includes a valve body, a spring, and a piston. The valve body has a through hole running along the axis inside. The first one-way valve 320 is installed in the interface 310 of the container 300. The top of the through hole is connected to the container 300, and the bottom of the through hole faces downwards from the container 300. The spring and piston are installed in the through hole. The spring connects the inner wall of the through hole to the piston. The spring pushes the piston downwards. The through hole is a stepped hole that is larger at the top and smaller at the bottom, that is, the through hole is divided into an upper section and a lower section. The diameter of the upper section is larger than that of the lower section. When the piston moves to the lower section of the through hole, the piston seals the lower section of the through hole. When the connector 210 is inserted into the interface 310, a plug is provided on the upper surface of the connector 210. The plug is vertically positioned upwards. The plug is inserted into the bottom of the through hole of the first one-way valve 320. The plug pushes the piston upwards to the upper section, and the upper and lower sections of the through hole are connected, realizing the connection between the interface 310 and the connector 210.

[0048] Understandably, the top cover 340 is provided with a vertically penetrating air inlet, and the second one-way valve 350 is disposed in the air inlet of the top cover 340. The second one-way valve 350 includes a valve body, a valve core, and a spring. The valve body is provided with a vertically penetrating through hole, and the valve core is slidably disposed in the through hole. An annular protrusion is disposed at the top of the through hole, and the spring is disposed in the through hole. The spring pushes the valve core upward to abut against the annular protrusion, thereby sealing the through hole. When the aviation fuel in the container 300 is delivered to the filling hole 220 by the filling pipeline 200, the pressure in the container 300 decreases, while the external air pressure is greater than the air pressure in the container 300. This causes the external air to push the valve core of the second one-way valve 350 downward against the spring force, thereby allowing external air to replenish the container 300, balancing the pressure between the container 300 and the external air pressure, and thus enabling the filling pipeline 200 to smoothly deliver the aviation fuel in the container 300.

[0049] Reference Figure 4 As shown, it can be understood that there are multiple ways in which the oil injection line 200 generates power to transport aviation oil.

[0050] For example, an inlet check valve is installed at connector 210, with the flow direction from the outside to the oil filling pipeline 200. An outlet check valve is installed at oil filling hole 220, with the flow direction from the inside of oil filling pipeline 200 to the outside. A piston cylinder is installed in oil filling pipeline 200, connecting connector 210 and oil filling hole 220. A piston is installed in the piston cylinder, with one end of the piston connected to a piston rod. The piston rod passes through the side wall of housing 100 and is located outside. The piston moves by pushing or pulling the piston rod. When the piston compresses the volume in the piston cylinder, the air pressure in the piston cylinder increases, causing the aviation oil in the piston cylinder to be output to the outside through the outlet check valve of oil filling hole 220. When the piston returns to its original position, the air pressure in the piston cylinder decreases. Since the oil filling hole 220 of oil filling pipeline 200 is closed by the outlet check valve, the liquid in container 300 is replenished into the piston cylinder through the inlet check valve to balance the air pressure in the piston cylinder.

[0051] Alternatively, an electric hydraulic pump can be installed in the oil filling line 200 to generate power to deliver oil from the connector 210 to the oil filling hole 220.

[0052] Before using the oil filling device, the container is removed from the mounting cavity 120 on the side wall of the housing 100. After opening the top cover 340 of the container 300, aviation oil is added to the container 300. Then, the container 300 filled with aviation oil is reinstalled into the mounting cavity 120 of the housing 100. The connector 210 of the mounting cavity 120 is inserted into the interface 310 at the bottom of the container 300, so that the connector 210 pushes the first one-way valve 320 to move into the container 300, thereby connecting the oil filling pipeline 200 and the container 300. This allows the oil filling pipeline 200 to deliver the aviation oil in the container 300 to the oil filling hole 220. The maintenance personnel align the oil filling hole 220 with the oil tank filling port of the turnout turner and inject aviation oil. Meanwhile, the second one-way valve 350 helps the outside air to enter the container 300, maintaining the air pressure balance between the container 300 and the outside.

[0053] The container 300 for storing aviation fuel is integrated into the housing 100 of the fuel injection device, eliminating the need to place the container 300 on the ground to avoid affecting the fuel injection operation. Furthermore, when the aviation fuel in the container 300 is depleted, the fuel injection device can continue to operate by replacing it with another container 300 filled with aviation fuel, thereby improving the fuel injection efficiency of the turnout rotator.

[0054] In some embodiments, refer to Figure 4As shown, the length of container 300 in the vertical direction is less than the length of mounting cavity 120 in the vertical direction. Interface 310 is set on the bottom wall of container 300, and connector 210 is set on the bottom wall of mounting cavity 120. Connector 210 is set vertically upward. There is a space between the outer wall of container 300 and the inner wall of mounting cavity 120. Container 300 can rotate around the vertical axis in mounting cavity 120. The outer wall of connector 210 is provided with external thread. Interface 310 is a round hole. The inner wall of interface 310 is provided with internal thread. The external thread of connector 210 and the internal thread of interface 310 are engaged.

[0055] The interface 310 of the container 300 is threadedly connected to the connector 210 of the oil filling line 200, which helps to improve the sealing performance, prevent the aviation oil in the container 300 from leaking from the interface 310, and the container 300 can be fixed in the mounting cavity 120.

[0056] The container 300 is easy to install and remove. Rotating the container 300 gradually moves it upwards, causing the second one-way valve 320 to return to its original position and seal the interface 310. After moving the container 300 upwards again, the interface 310 is disengaged from the connector 210. Then, the container 300 can be moved horizontally to detach it from the mounting cavity 120. When installing the container 300 in the mounting cavity 120, after offsetting the container 300 and connector 210 vertically, move the container 300 horizontally into the mounting cavity 120 so that the interface 310 and connector 210 are aligned. Then, move the container 300 downwards so that the connector 210 is inserted into the interface 310. Finally, rotate the container 300 to make the connector 210 and interface 310 threadedly engage.

[0057] In some embodiments, refer to Figures 1 to 3 As shown, the outer wall of the container 300 is cylindrical, and multiple anti-slip grooves 360 are provided on the outer wall of the container 300 at intervals along the circumference.

[0058] The anti-slip groove 360° allows the container 300 to be rotated more easily by maintenance personnel, and helps the interface 310 of the container 300 and the threaded engagement of the connector 210 to be tighter.

[0059] In some embodiments, refer to Figure 2 and Figure 4 As shown, a stop 130 is provided at the bottom of the mounting cavity 120. The stop 130 is located on the periphery of the container 300. When the container 300 is installed in the mounting cavity 120 and the connector 210 and the interface 310 are engaged, the stop 130 abuts against the outer wall of the container 300. The length of the container 300 in the vertical direction is less than the distance from the top of the stop 130 to the top wall of the mounting cavity 120, so that the container 300 can be inserted into the mounting cavity 120 from above the stop 130.

[0060] The container 300 is inserted into the mounting cavity 120 from above the stop 130. Then the container 300 moves downward along the side wall of the stop 130 toward the mounting cavity 120. Finally, the interface 310 and the connector 210 cooperate, so that the stop 130 can form a support around the container 300, preventing the container 300 from tilting or falling out of the mounting cavity 120 and causing the interface 310 and connector 210 to loosen.

[0061] In some embodiments, refer to Figure 1 and Figure 4 As shown, the outer wall of container 300 protrudes outside the shell 100.

[0062] The rotation of container 300 is achieved by rubbing the protruding outer wall of container 300.

[0063] In some embodiments, refer to Figures 1 to 4 As shown, the sidewall of container 300 is made of transparent material, and the outer sidewall of container 300 is provided with volume scale so that maintenance personnel can observe the remaining amount of aviation fuel in container 300 and replace container 300 in a timely manner.

[0064] In some embodiments, refer to Figure 4 As shown, the turnout rotator oil injection device also includes a power supply 400 and an oil pump 500.

[0065] Both the power supply 400 and the oil pump 500 are located in the inner cavity 110 of the housing 100. The power supply 400 supplies power to the oil pump 500. The oil pump 500 is connected to the oil filling line 200. After the oil pump 500 is started, it delivers aviation oil from the connector 210 to the oil filling hole 220 in the oil filling line 200.

[0066] The oil pump 500 drives the flow of aviation oil in the oil injection line 200, making the oil injection operation of the oil injection device more convenient.

[0067] In some embodiments, refer to Figure 4 As shown, the turnout rotator oil injection device also includes a handle 600 and a controller 700. The handle 600 is located on the top of the housing 100 and is vertically mounted on the top of the housing 100. The controller 700 is located inside the handle 600, and the button of the controller 700 extends out of the handle 600. The controller 700 is electrically connected to the oil pump 500 and controls the opening and closing of the oil pump 500. The electrical connection wire of the controller 700 is built into the inside of the handle 600 and extends downward into the inner cavity 110 of the housing 100.

[0068] Maintenance personnel operate the oil injection device by holding handle 600. By pressing the button on handle 600, the controller 700 controls the start and stop of the oil pump 500, making the oil injection operation of the oil injection device more convenient.

[0069] This utility model embodiment also provides an oil filling device, which is applied to the turnout rotary oil filling device as described in the above embodiment.

[0070] The turnout rotator oil filling device is equipped with multiple containers 300, at least one container 300 is detachably installed in the mounting cavity 120 of the housing 100, and at least one container 300 is replenished with aviation oil by an oil filling device.

[0071] One container 300 is installed in the mounting cavity 120 of the oiling device. When maintenance personnel use the oiling device to inject aviation oil into the oil tank of the turnout rotator, the top cover 340 of the other container 300 is opened and the oil filling device is used to replenish the aviation oil in the other container 300. When the aviation oil in the container 300 of the oiling device is exhausted, the other container 300 can be replaced and the device can continue to be used without waiting for the container to be replenished with aviation oil, thus improving the oiling efficiency of the turnout rotator.
