[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-6As shown, the encoder layout structure of the fracturing pump skid provided in this embodiment includes a housing 1 and a circuit board 15 installed inside the housing 1. An encoder 19 is installed on the circuit board 15. A sealing cover 2 is installed on the housing 1. A first sealing gasket 10 is installed on the sealing cover 2. A wire hole 11 is provided on the housing 1. A second sealing gasket 12 is installed on the wire hole 11. A guide assembly is installed on the sealing cover 2. A limit assembly is installed on the guide assembly. By setting the sealing cover 2 and the first sealing gasket 10 to cooperate with each other, the sealing performance of the housing 1 can be increased. By setting the wire hole 11, it is easy to pass the wire through. By setting the second sealing gasket 12, the sealing performance of the wire hole 11 can be increased.

[0025] In this embodiment, as Figure 4 As shown, a side rod 16 is mounted on the circuit board 15, one end of which is connected to the housing 1. A bottom rod 20 is mounted on both the bottom and top of the circuit board 15, one end of which is connected to the housing 1. By setting the bottom rod 20 and the side rod 16 to cooperate with each other, the circuit board 15 can be easily supported. The encoder 19 is soldered onto the circuit board 15, and the encoder 19 can be laid out and installed.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the guide assembly includes a limiting plate 3, a guide ring 5, a connecting block 6, a connecting rod 7, and a guide rod 17. The guide rod 17 is mounted on the housing 1, and the guide ring 5 is slidably mounted on the guide rod 17. The guide ring 5 has a guide hole 18 that cooperates with the guide rod 17. The connecting block 6 is mounted on the guide ring 5, and the connecting rod 7 is mounted on the connecting block 6. A limiting plate 3 is mounted on one end of the guide rod 17. By setting the guide ring 5 and the guide rod 17 to slide together, the guide ring 5 slides on the guide rod 17, thus facilitating the movement of the limiting assembly to limit the installation of the sealing cover 2. The guide ring 5 and the guide rod 17 cooperate to facilitate guiding and limiting the limiting assembly. The limiting assembly includes an insert block 14 and a moving plate 8. The moving plate 8 is mounted on one end of the connecting rod 7, and the insert block 14 is mounted on the moving plate 8. Slots 13 that cooperate with the insert block 14 are provided on both the housing 1 and the sealing cover 2. The insert 14 and slot 13 cooperate with each other. The sliding plate 8 slides, and the guide ring 5 slides on the guide rod 17, thereby driving the insert 14 to move and insert the insert 14 into the slot 13. This facilitates the limiting of the installed sealing cover 2 and makes it easy to remove the sealing cover 2 to open the housing 1 for coding layout. The guide ring 5 is connected to the limiting plate 3 through the spring 4. By setting the spring 4, the sliding plate 8 is released, the spring 4 extends, and thus drives the guide ring 5 to move. When the guide ring 5 moves, it drives the sliding plate 8 to move, and thus drives the insert 14 to move and insert the insert 14 into the slot 13 to limit the installed sealing cover 2. The sliding plate 8 is equipped with a handle 9 and an anti-slip pad. By setting the handle 9, it is easy to pull the sliding plate 8, and thus easy to slide the insert 14 out of the slot 13 and to facilitate the handling of the sealing cover 2. The anti-slip pad increases the friction of the handle 9.

[0027] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the encoder layout structure of the fracturing pump skid of the sand mixing truck provided in this embodiment is as follows:

[0028] Step 1: Solder encoder 19 onto circuit board 15 to install encoder 19;

[0029] Step 2: Place the sealing cover 2 on the housing 1, release the moving plate 8, the spring 4 extends, and thus drives the guide ring 5 to move. When the guide ring 5 moves, it drives the moving plate 8 to move, and thus drives the insert block 14 to move. Insert the insert block 14 into the slot 13 to limit the installation of the sealing cover 2.

[0030] In summary, in this embodiment, according to the encoder layout structure of the fracturing pump skid of the sand mixing truck, the sealing cover 2 and the first sealing gasket 10 cooperate to increase the sealing performance of the housing 1. The wire hole 11 facilitates the passage of wires. The second sealing gasket 12 further enhances the sealing performance of the wire hole 11. The bottom rod 20 and the side rod 16 cooperate to support the circuit board 15. The encoder 19 is soldered onto the circuit board 15, allowing for its layout and installation. The guide ring 5 is slidably connected to the guide rod 17. The sliding guide ring 5 slides on the guide rod 17, which facilitates the movement of the limiting component to limit the installation of the sealing cover 2. The cooperation between the guide ring 5 and the guide rod 17 facilitates the movement of the limiting component. To limit the movement, the insert 14 and slot 13 are designed to cooperate with each other. The sliding plate 8 slides the guide ring 5 on the guide rod 17, thereby moving the insert 14 and inserting it into the slot 13. This allows the installed sealing cover 2 to be limited, and also allows the sealing cover 2 to be disassembled to open the housing 1 for coding layout. By setting the spring 4, the sliding plate 8 is released, and the spring 4 extends, thereby moving the guide ring 5. When the guide ring 5 moves, it moves the sliding plate 8, which in turn moves the insert 14, inserting it into the slot 13 to limit the installed sealing cover 2. The handle 9 allows the sliding plate 8 to be pulled, making it easy to slide the insert 14 out of the slot 13 and to move the sealing cover 2. The anti-slip pad increases the friction of the handle 9.
