[0004] (2) It is difficult to connect the oil gun to the wheel oil cup online;

[0005] (3) The on-site temperature is high, the working environment is harsh, and the labor intensity is high;

[0006] (4) The center distance of the trolley wheels is deviated. Due to the counterweight and other reasons, the center height of the wheels is also deviated. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of difficult, time-consuming, labor-intensive, and poor oiling effect of online oiling docking of existing trolley wheels. It provides a driven self-centering oiling mechanism for trolley wheels, which realizes the automatic docking of the oiling component and the oil cup of the trolley wheel, realizes automatic oiling during online operation of the trolley, can adapt to various deviations of the trolley, improve oiling efficiency and docking accuracy, and increase the success rate of oiling.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A driven self-centering oil injection mechanism for a trolley wheel includes a drive unit, an oil gun assembly, a driven wheel assembly, and a limit assembly mounted on a follower platform.

[0010] The drive unit includes a linear guide rail and a guide block connected to a drive motor. A pair of rotating shaft seats are connected to the guide block. A telescopic shaft passes horizontally between the two rotating shaft seats. A rotating pair is provided between the telescopic shaft and the rotating shaft seats. The axis of the telescopic shaft is set parallel to the wheel axle of the trolley wheel.

[0011] The driven wheel assembly includes a telescopic shaft and a fork plate that cooperate with each other. The end of the telescopic shaft facing the trolley wheel is fixedly connected to the middle of the fork plate. Each end of the fork plate is connected to an auxiliary wheel. The auxiliary wheels are in contact with the outer ring surface of the trolley wheel to realize the follow-up movement of the oil injection mechanism and the trolley wheel.

[0012] The oil gun assembly is located on one side of the driven wheel assembly, and the limiting assembly is located on the other side of the driven wheel assembly;

[0013] The oil gun assembly is fixed on a vertical mounting plate. A pair of horizontal connecting blocks are fixed on the side of the mounting plate. One end of the connecting block is fixedly connected to the telescopic shaft. When the auxiliary wheel is in contact with the trolley wheel, the oil outlet of the oil gun assembly is set directly opposite the oil filling port of the trolley oil cup.

[0014] The limiting component is fixed to the other side of the telescopic shaft by a horizontal connecting block 2, and a counterweight is also provided on it to balance the weight of the oil gun assembly.

[0015] Furthermore, the follower platform includes a pair of parallel slide rails, each slide rail is connected to a pair of cooperating sliders, the sliders are fixed below a horizontal follower plate, the follower plate and the slide rails form a sliding guide engagement, and the axis of the slide rails is set parallel to the trolley rails.

[0016] Furthermore, the bifurcated plate is a planar plate structure with a bend in the middle, and the bending angle α at the bend is an obtuse angle. The bifurcated plates are symmetrically distributed above and below the bend with the bend as the center line.

[0017] Furthermore, given the radius R of the trolley wheel, the distances from both auxiliary wheels to the oil outlet are equal to the radius of the trolley wheel, ensuring that the oil outlet position is the same as the oil injection port position.

[0018] Furthermore, the limiting component includes a vertical column, a connecting block two fixed to the inner side of the column, a counterweight fixed to the upper outer side of the column, and a U-shaped stop on the outer side of the column, with the opening of the U-shaped stop facing the column, and a buffer gap between the column and the U-shaped stop.

[0019] Compared with the prior art, the advantages of the technical solution of the present invention are as follows:

[0020] (1) The drive device of the present invention is used to drive the telescopic movement of the driven wheel mechanism. It is electrically driven and equipped with a UPS power supply to prevent the equipment from being unable to detach and thus being damaged after a system failure and power outage.

[0021] (2) The oil gun assembly of the present invention is used to connect to the oil cup of the trolley and maintain pre-pressure to achieve oil injection and sealing. When the wheel is in place, the drive mechanism pushes the oil gun assembly forward to connect to the oil injection port of the wheel oil cup and maintains an adjustable pre-pressure to achieve sealing during oil injection.

[0022] (3) The limiting device of the present invention is used to limit the swing amplitude of the driven wheel, keep the driven wheel mechanism within a limited swing angle, and configure a counterweight to balance the weight of the oil gun assembly;

[0023] (4) The driven wheel mechanism of the present invention is used to realize the follow-up movement of the oil injection mechanism and the trolley wheel. The driven wheel assembly is equipped with two driven wheels. For a known diameter of the trolley wheel, the center of the circle can be determined by two points on the circle, thereby realizing the automatic centering of the oil injection gun and the oil cup of the trolley wheel.

[0028] To make the present invention clearer, the following description, in conjunction with the accompanying drawings, further illustrates a driven self-centering oil injection mechanism for a trolley wheel according to the present invention. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the present invention.

[0029] See Figure 1 A driven self-centering oil injection mechanism for trolley wheels, characterized in that:

[0030] The system includes a drive unit 2, an oil gun assembly 3, a driven wheel assembly 4, and a limit assembly 5, all mounted on a follower platform 1. The follower platform 1 includes a pair of parallel slide rails 11, with a pair of cooperating sliders 12 connected to each slide rail 11. The sliders 12 are fixed below a horizontal follower plate 13. The follower plate 13 and the slide rails 11 form a sliding guide engagement, and the axis of the slide rails 11 is parallel to the trolley rail 8.

[0031] See Figure 1 and Figure 2 The drive device 2 includes a linear guide rail 21 and a guide block 22 connected to the drive motor. A pair of rotating shaft seats 23 are connected to the guide block 22. A telescopic shaft 41 passes horizontally between the two rotating shaft seats 23. A rotating pair 23a is provided between the telescopic shaft 41 and the rotating shaft seats 23. The axis of the telescopic shaft 41 is parallel to the axle of the trolley wheel 6.

[0032] See Figure 1 and Figure 3The driven wheel assembly 4 includes a telescopic shaft 41 and a fork plate 42 that cooperate with each other. The end of the telescopic shaft 41 facing the trolley wheel 6 is fixedly connected to the middle of the fork plate 42. The fork plate 42 is a planar plate structure with a bend in the middle, and the bending angle of its bend 42a is an obtuse angle. The fork plate 42 is symmetrically distributed above and below its bend 42a as the center line.

[0033] Auxiliary wheel 43 is connected to each end of the fork plate 42. The auxiliary wheel 43 is in contact with the outer ring surface 6a of the trolley wheel 6 to realize the follow-up movement of the oil injection mechanism and the trolley wheel.

[0034] The oil gun assembly 3 is located on one side of the driven wheel assembly 4, and the limiting assembly 5 is located on the other side of the driven wheel assembly 4;

[0035] The oil gun assembly 3 is fixed on a vertical mounting plate 9. A pair of horizontal connecting blocks 10 are fixed on the side of the mounting plate 9. One end of the connecting block 10 is fixedly connected to the telescopic shaft 41. When the auxiliary wheel 43 is in contact with the trolley wheel 6, the oil outlet 3a of the oil gun assembly 3 is set directly opposite the oil filling port 7a of the trolley oil cup 7.

[0036] See Figure 1 The limiting component 5 is fixed to the other side of the telescopic shaft 41 by a horizontal connecting block 2 51. It includes a vertical column 53, the connecting block 2 51 is fixed to the inner side of the column 53, and the counterweight block 52 is fixed to the upper outer side of the column 53 to balance the weight of the oil gun assembly.

[0037] A U-shaped stop 54 is also provided on the outside of the column 53. The opening 54a of the U-shaped stop 54 faces the column, and a buffer gap is provided between the column 53 and the U-shaped stop 54.

[0038] See Figure 1 and Figure 4 Given that the radius R of the trolley wheel 6 is known, the distances from the two auxiliary wheels 43 to the oil outlet 3a are equal to the radius of the trolley wheel 6, ensuring that the oil outlet position is the same as the oil filling position. In use, the guide block 22 is pushed towards the trolley wheel 6 by the drive device 2, thereby driving the telescopic shaft 41 on the guide block 22 and the fork plate 42 to approach the trolley wheel 6 together until the auxiliary wheel 43 on the fork plate 42 is in contact with the outer ring surface 6a of the trolley wheel 6. When the trolley is running, the auxiliary wheel 43 can also ensure that the oil filling mechanism and the trolley wheel move together, and the oil outlet 3a of the oil gun assembly 3 is directly opposite the oil filling port 7a of the trolley oil cup 7, improving the alignment accuracy of the two.

[0039] The device of the present invention realizes automatic alignment between the oil injection gun and the oil cup of the trolley wheel, which improves the success rate of oil injection and reduces the intensity of manual labor.
