It should be understood that the specific features in the embodiments of this application and the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.

[0027] As Figures 1-6 shown, a rotary joint for a brake fluid filling machine for mining truck assembly includes a transition valve block 1, a tubing assembly and a rotary seal joint 5;

[0028] The transition valve block 1 includes an oil injection end and an oil outlet end, and the oil injection end is connected to the filling gun head 6;

[0029] The tubing assembly includes not less than two high-pressure oil pipes 4. One end of each high-pressure oil pipe 4 is connected to the oil outlet end of the transition valve block 1, and the other end is connected to the rotary seal joint 5;

[0030] The rotary seal joint 5 is connected between the high-pressure oil pipe 4 and the brake fluid reservoir 71 on the brake pedal assembly 7. Through the rotary joint of the brake fluid filling machine of the present utility model, it is possible to realize vacuum filling of brake fluid during the assembly process of mining trucks, improving the quality and efficiency of the assembly process.

[0031] In some embodiments, as Figure 1 、 Figure 2 shown, the tubing assembly further includes straight-through joints 2 installed at both ends of the high-pressure oil pipe 4. The straight-through joint 2 at one end of the high-pressure oil pipe 4 is connected to the oil outlet end of the transition valve block 1, and the straight-through joint 2 at the other end is connected to the rotary seal joint 5. Among them, the high-pressure oil pipe 4 adopted has an explosion-proof steel ring wound inside, with good pressure resistance and high safety; the high-pressure oil pipe 4 is connected to the transition valve block 1 and the rotary seal joint 5 through the straight-through joint 2, which is more convenient.

[0032] In some embodiments, as Figure 1 、 Figure 2 shown, the straight-through joint 2 is installed on the high-pressure oil pipe 4 through a clamp 3, and the clamp 3 adopts a C-type worm drive hoop, which is firmly and conveniently installed.

[0033] In some embodiments, as Figure 5As shown, the straight-through joint 2 includes a bamboo joint head end 21 and a threaded end 22. The bamboo joint head end 21 is used to connect the high-pressure oil pipe 4. The high-pressure oil pipe 4 is connected through the cooperation of the bamboo joint head end 21 and the clamp 3, with high stability. The transition valve block 1 and the rotary seal joint 5 are connected through the threaded end 22, which is convenient for disassembly and assembly. Through the straight-through joint 2, the brake fluid in the filling gun head 6 flows into the high-pressure oil pipe 4 through the transition valve block 1, and then flows into the brake fluid kettle 71 from the high-pressure oil pipe 4 through the rotary seal joint 5, making the liquid injection more convenient.

[0034] In some embodiments, as Figure 1 , Figure 2 shown, the oil pipe assembly includes two high-pressure oil pipes 4. During use, one high-pressure oil pipe 4 serves as the filling pipeline for the brake fluid, and the other serves as the vacuum pumping pipeline.

[0035] In some embodiments, as Figure 3 shown, the rotary seal joint 5 includes a rotary seal head 52 for connecting the brake fluid kettle 71, a connection block 53 for connecting the straight-through joint 2, and a snap ring 51. The snap ring 51 is rotatably installed on the connection block 53, and the rotary seal head 52 is fixedly connected to the snap ring 51. The rotary seal joint 5 can be quickly installed on the brake fluid kettle 71 to play a sealing role. During installation, only by rotating the rotary seal head 52 can it be tightened, and the connection block 53 does not rotate.

[0036] In some embodiments, as Figure 3 shown, the rotary seal head 52 and the snap ring 51 are fixed by an internal hexagon screw 54, with high installation stability and good sealing performance.

[0037] In some embodiments, the rotary seal head 52 and the brake fluid kettle 71 are connected by threads. An internal thread is provided on the rotary seal head 52. When filling the oil, the rotary seal head 52 is screwed into the threaded filling port of the brake fluid kettle 72. The threaded connection has high stability and good sealing performance. Additionally, as Figure 4 shown, a threaded hole 11 for connecting the straight-through joint 2 is provided at the oil outlet end of the transition valve block 1. The threaded connection is more convenient; the oil filling end of the transition valve block 1 is used to clamp the filling gun head 6.

[0038] In some embodiments, the snap ring 51 is composed of two half snap rings, which is convenient for installing the snap ring 51 on the connection block 53.

[0039] Combined with Figure 6 shown, the usage process is as follows:

[0040] 1) When evacuating, clamp the filling gun head 6 on the transition valve block 1, start the vacuum pump, open the vacuum pressure maintaining valve, vacuum valve, and gun vacuum valve. After 2 seconds, open the vacuum sensor valve, and evacuate through one of the high-pressure oil pipes 4. The primary vacuum starts and ends after reaching the predetermined time for the primary vacuum process;

[0041] 2) After evacuating to the predetermined time, close the vacuum pressure maintaining valve, and the system enters the leak detection process, which ends after reaching the predetermined time;

[0042] 3) When the leak detection time is up, under normal circumstances, the system enters the secondary vacuum process. Open the vacuum pressure maintaining valve again for the secondary vacuum (repeating the vacuum process), which ends after reaching the predetermined time;

[0043] 4) When filling, start the filling pump, open the filling valve of the filling gun head 6, and fill the brake fluid into the brake fluid reservoir 71 through the other high-pressure oil pipe 4. The filling process ends after filling to the predetermined pressure and reaching the pressure maintaining set time;

[0044] 5) After filling is completed, the system will suck the oil in the high-pressure oil pipe 4 back into the fuel tank. Open the blowing valve and the back suction valve. At the same time, open the filling valve of the filling gun head 6. The back suction ends after reaching the predetermined time.

[0045] The brake fluid filling machine adapter for mining truck assembly of the present utility model is connected to the filling gun head through the transition valve block at one end and to the brake fluid reservoir through the rotary seal joint at the other end, realizing the vacuum filling of brake fluid during the mining truck assembly process, improving the product quality, enhancing the manufacturing efficiency, solving the problem that air cannot be discharged inside the whole system, resulting in soft brakes and requiring manual repeated air exhaust treatment. The structure is simple, the operation is convenient, and it is easy to implement.

[0046] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features contained in other embodiments rather than other features, the combination of the features of different embodiments also means being within the protection scope of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
