[0027] The butt joint device for oil injection of the sintering trolley is characterized in that the air supply channel 3 and the one-way valve 4 are arranged on the butt joint base 1, and the compressed air is connected before and after oil supply, so that the compressed air acts on the butt joint 11 after sequentially passing through the air supply channel 3 and the oil channel 2, the butt joint 11 position is blown and cleaned, the butt joint 11 is prevented from being bonded with impurities, the phenomenon of dry nodules is avoided, the oil passage is ensured to be smooth, the oil injection efficiency is improved, impurities or dry nodules are prevented from being easily injected into the wheel system of the sintering trolley along with the lubricating oil, the service life of the wheel system of the sintering trolley is ensured, and the one-way valve 4 is arranged, the one-way valve 4 has the effect of ensuring that the lubricating oil passes in one direction, and the compressed gas is prevented from entering the oil supply device of the lubricating oil, and the oil supply effect is ensured.

[0028] In some embodiments, the butt joint 11 is in a flared shape. Specifically, the butt joint 11 is arranged at the end of the butt joint base 1 and is used for butt joint with the wheel oil inlet. The diameter of the butt joint 11 gradually increases along the direction from inside to outside, and when the wheel oil inlet is matched, the butt joint 11 can play a guiding positioning role for the butt joint of the oil inlet, ensure that the butt joint 11 is coaxial with the oil inlet, and make the two seal together, so that they can work normally under a certain oil pressure.

[0029] In some embodiments, the outer periphery of the butt joint base 1, where the butt joint 11 is arranged, is provided with a butt joint head 5, the butt joint head 5 is provided with a butt joint hole 51, and the butt joint hole 51 is arranged in a position opposite to and coaxial with the butt joint 11.

[0030] In this design, the butt joint hole 51 can play a guiding role for the alignment of the butt joint 11 and the wheel oil inlet, and increase the convenience of connecting the butt joint 11 and the wheel oil inlet.

[0031] In some embodiments, the butt joint hole 51 is in a flared shape. Specifically, the diameter of the butt joint hole 51 gradually increases along the direction from inside to outside, so that the butt joint hole 51 is in a trumpet shape, the butt joint range with the wheel oil inlet can be expanded, and the butt joint hole 51 and the wheel oil inlet can be on the same axis under a certain error, so that they can be connected quickly and accurately.

[0032] In this design, through the design of the flared butt joint 11 and the flared butt joint hole 51, the alignment accuracy of the butt joint 11 and the wheel oil inlet of the sintering trolley can be ensured, the error range during alignment is expanded, the butt joint 11 can be ensured to contact the wheel oil cup, and the oiling operation can be smoothly completed.

[0033] In some embodiments, the minimum diameter of the butt joint hole 51 is greater than or equal to the maximum diameter of the butt joint 11, that is, the diameter of the necked end of the butt joint hole 51 is greater than or equal to the diameter of the flared end of the butt joint 11, so that the butt joint hole 51 can play a guiding role for the butt joint of the wheel oil inlet.

[0034] In some embodiments, the adapter 5 is detachably connected with the adapter seat 1. Specifically, the adapter 5 is connected with the adapter seat 1 in a threaded connection manner. In this design, the convenience of disassembling the adapter 5 and the adapter seat 1 can be increased.

[0035] In some embodiments, the one-way valve 4 is arranged on the side of the oil passage 2 away from the adapter interface 11 at the position where the oil passage 2 communicates with the gas supply channel 3, and the one-way valve 4 comprises a ball and a spring. The spring exerts a spring force on the ball in a direction away from the adapter interface 11, so that the ball can block the oil inlet end of the oil passage 2 under the spring force, or open the oil inlet end of the oil passage 2 under the pressure of the lubricating oil. Specifically, the end of the oil passage 2 away from the adapter interface 11 is formed with a stepped surface, and the oil inlet end of the oil passage 2 is formed in the stepped surface, so that the ball can be accommodated in the oil passage 2 and can block or open the oil inlet end of the oil passage 2. The ball is arranged at the end of the spring away from the adapter interface 11, so that the ball can block the oil inlet end of the oil passage 2 under the spring force of the spring, to prevent the compressed gas from entering the oil supply device. However, during oil filling, the ball can move in the direction towards the adapter interface 11 under the pressure of the introduced lubricating oil, to overcome the spring force and allow the lubricating oil to enter the oil passage 2 through the oil inlet end of the oil passage 2.

[0036] In some embodiments, the adapter seat 1 is provided with an oil supply port 12 communicating with the oil inlet end of the oil passage 2 and a gas supply port 13 communicating with the gas inlet end of the gas supply channel 3, and the oil supply port 12 and the gas supply port 13 are arranged opposite to each other. The oil supply port 12 is connected with a lubricating oil conduit, the lubricating oil enters the oil passage 2 through the oil supply port 12, flows out from the adapter interface 11 through the one-way valve 4, and then enters the wheel oil inlet port to be delivered to the inside of the wheel. The gas supply port 13 is connected with a compressed gas pipeline, and the compressed gas provided by the compressed gas pipeline enters the gas supply channel 3 through the gas supply port 13, and then flows out through the oil passage 2 to act on the adapter interface 11. In addition, the opposite arrangement of the oil supply port 12 and the gas supply port 13 facilitates the arrangement of the lubricating oil conduit and the compressed gas pipeline, so that the overall structure is more compact.

[0037] In some embodiments, the adapter seat 1 is provided with a connecting hole 14 for connecting with the oil filling device, and the adapter seat 1 is axially connected with the oil filling device through the connecting hole 14. The connecting hole 14 can be a threaded hole, which increases the convenience of disassembling the adapter seat 1 and the oil filling device.

[0038] In some embodiments, the connecting hole 14 is arranged opposite to the adapter interface 11.

[0039] In this design, when the adapter seat 1 is connected with the oil filling device through the connecting hole 14, the adapter interface 11 can be located at the end of the oil filling device, which facilitates the docking of the adapter interface 11 and the wheel oil inlet port.
