DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model but not to limit the scope of the utility model.

[0025] Embodiment: refer to Figures 1-6 A filling pump reversing equipment, comprising a disc box 1, further comprising: a mounting disc 2 fixedly installed in the disc box 1, the mounting disc 2 is provided with a first guide hole 4, the first guide hole 4 is provided with multiple groups and is distributed in a circle on the mounting disc 2, preferably 2-10 groups, in the embodiment, preferably 6 groups (6 groups of first guide holes 4 are respectively A group, B group, C group, D group, E group and F group); the mounting disc 2 is provided with a rotating hole 3, the mounting column 7 is rotatably installed in the rotating hole 3, the mounting column 7 is provided with a second guide hole 8, and the second guide hole 8 is communicated with one of the first guide holes 4.

[0026] The initial state is that the second guide hole 8 is aligned with the first guide hole 4 of the A group, and the paste is filled from the filling pump → the second guide hole 8 → the first guide hole 4 of the A group → the corresponding branch pipe.

[0027] When the A group pipeline is blocked, rotate the mounting column 7 to align the second guide hole 8 with the B group first guide hole 4, switch to the standby branch to continue filling, and so on. In this process, the blocked pipeline can be cleaned.

[0028] The configuration of the six groups of guide holes significantly improves the fault tolerance of the system. In theory, it can cope with five consecutive pipe blockages without stopping, far exceeding the one-time fault tolerance of traditional double pipelines.

[0029] Referring to Figure 2 and Figure 4 , the bottom of the disc box 1 is fixedly installed with a motor 11, and the output shaft of the motor 11 is fixedly connected with the mounting column 7. Starting the motor 11 drives the mounting column 7 to rotate by the motor 11, thereby automatically and quickly switching the pipeline.

[0030] Referring to Figure 2 and Figure 6 , the top of the mounting column 7 is fixedly installed with a spherical shell 9, and the spherical shell 9 is hingedly connected with a connecting flange 10. The spherical shell 9 allows the connecting flange 10 to freely deflect within a certain angle range through the hinged design, which can compensate for the displacement caused by installation errors or pipeline vibration, reduce the risk of stress concentration of the pipeline, and allow the mounting column 7 to freely switch the communication pipeline after being connected with the filling pump.

[0031] In addition, during the paste filling process, the rotational freedom of the spherical shell 9 helps to adapt to the spatial layout of different branches, especially for complex pipeline layout scenarios underground.

[0032] Referring to Figure 2 and Figure 5 , the disc box 1 is fixedly installed with a mounting pipe 5, which is in communication with the first guide hole 4. The mounting pipe 5 is coaxial with the discharge port of the first guide hole 4. The mounting pipe 5 is fixedly installed with a one-way valve 6. When the second guide hole 8 is in communication with other first guide holes 4, high-pressure air or water and other cleaning media can be injected into the corresponding first guide hole 4 through the one-way valve 6 to dredge the blocked pipeline.

[0033] Referring to Figure 2 , Figure 4 and Figure 6 , the mounting column 7 is fixedly installed with a mounting cylinder 13, and the mounting cylinder 13 is slidingly installed with a piston plate 14. The piston plate 14 is fixedly installed with a top rod 16, and the top rod 16 is sleeved with a spring 15. The two ends of the spring 15 are fixedly connected with the piston plate 14 and the mounting cylinder 13, respectively. The top of the disc box 1 is fixedly installed with a wedge block 17. When the internal pressure of the mounting column 7 increases, the piston plate 14 drives the top rod 16 to extend. The extended top rod 16 abuts against the wedge block 17. The bottom of the mounting column 7 is provided with an alignment hole 18, and the bottom of the disc box 1 is fixedly installed with an alignment sensor 12.

[0034] In this embodiment, when one of the filling pipes is blocked, the pressure in the mounting column 7 increases, the increased pressure drives the piston plate 14 to slide, the piston plate 14 drives the extension of the top rod 16 and the contraction of the spring 15, the top rod 16 extends and abuts against the wedge block 17, in the process of the extension of the top rod 16, the inclined surface of the wedge block 17 cooperates with the top rod 16 to cause the deflection of the mounting column 7, thereby automatically switching the pipeline, in addition, in this process, the alignment sensor 12 senses the rotation of the mounting column 7 through the alignment hole 18, and then the single-chip microcomputer system controls the motor 11 to start, and the motor 11 drives the mounting column 7 to switch to the complete and connected pipeline.

[0035] In summary, the device has the following advantages:

[0036] Improved fault tolerance: By setting multiple groups of first guide holes 4 (such as group A, group B, etc.), even in the case of continuous multiple pipe blockages, the device can continue to work without stopping. In theory, it can cope with five consecutive single-pipe blockages without the need to stop for cleaning.

[0037] Automatic switching function: When it is detected that one of the filling pipes is blocked, the pressure in the mounting column 7 increases, triggering the sliding of the piston plate 14, which in turn drives the extension of the top rod 16 to abut against the wedge block 17, causing the deflection of the mounting column 7, thereby automatically switching to another unblocked pipeline.

[0038] Motor 11 assisted switching: The motor 11 is fixed at the bottom of the disc box 1, and its output shaft is connected with the mounting column 7, so that the motor 11 can be started to quickly and accurately switch the pipeline when needed, improving the work efficiency and the degree of automation.

[0039] Compensation for installation errors: The hinged design on the spherical shell 9 allows the connecting flange to freely deflect within a certain angle range, which helps to adapt to the spatial layout of different branch pipes and compensates for the displacement caused by installation errors or pipe vibration, reducing the risk of stress concentration in the pipeline.

[0040] Cleaning function: Each first guide hole 4 is equipped with a mounting pipe 5 and a one-way valve 6, which can be used to inject high-pressure air or water to clean the blocked pipeline when the second guide hole 8 is connected with other first guide holes 4, facilitating maintenance and cleaning.

[0041] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned technical content without departing from the scope of the technical solution of the present application, all still belong to the scope of the present application.
