The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model discloses a pipe clamp connection device for a mud pump, comprising: a pump pipe 10, a pump pipe 2 11 movably connected to the right end face of the pump pipe 10, a fixing bolt 13 threadedly connected at the connection between the pump pipe 10 and the pump pipe 2 11, the fixing bolt 13 passing through the pump pipe 10 and the pump pipe 2 11, a fixing nut 14 threadedly connected to the left end of the fixing bolt 13, and the fixing nut 14 being located on the left side of the pump pipe 10; and an upper pipe movably connected to the side surface of the connection between the pump pipe 10 and the pump pipe 2 11. The upper pipe clamp 1 is rotatably connected to the lower pipe clamp 2 via a rotating shaft 16 at its rear end. The upper surfaces of the upper pipe clamp 1 and the lower pipe clamp 2 are movably connected to a fixing bolt 2 4. The lower end of the fixing bolt 2 4 is threadedly connected to a fixing nut 2 5. The fixing bolt 2 4 passes through the upper pipe clamp 1 and the lower pipe clamp 2, and the fixing nut 2 5 is located on the lower surface of the lower pipe clamp 2. The left protective plate 3 is fixedly connected to the left surface of the upper pipe clamp 1 and the lower pipe clamp 2, and the right protective plate 15 is fixedly connected to the right surface of the upper pipe clamp 1 and the lower pipe clamp 2.

[0022] Specifically, pump pipe 10 and pump pipe 21 are movably connected at their end faces and are connected by fixing bolt 13 through the two pipes. The left end is locked with fixing nut 14 to prevent the pipes from separating. The upper pipe clamp ring 1 and the lower pipe clamp ring 2 are connected by a rotating shaft 16. The lower pipe clamp ring 2 can rotate around the rotating shaft 16 to facilitate quick opening and closing during installation. The two pipe clamp rings are radially locked by fixing bolt 24 and fixing nut 25 to tighten the two pipe clamp rings at the connection of the pump pipes, forming a circumferential pressure seal. The left protective plate 3 and the right protective plate 15 increase the length of the pipe clamp covering the pump pipe to prevent leakage.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper pipe clamp ring 1, lower pipe clamp ring 2, left protective plate 3, and right protective plate 15 cover pump pipe 10 and pump pipe 2 11. The left surface of the upper pipe clamp ring 1 is fixedly connected to the upper left retaining tooth 6, and the left surface of the lower pipe clamp ring 2 is fixedly connected to the lower left retaining tooth 7. The upper left retaining tooth 6 is located above the lower left retaining tooth 7, and the upper left retaining tooth 6 and the lower left retaining tooth 7 are intersected. The right surface of the upper pipe clamp ring 1 is fixedly connected to the upper right retaining tooth 8, and the right surface of the lower pipe clamp ring 2 is fixedly connected to the lower right retaining tooth 9. The upper right retaining tooth 8 is located above the lower right retaining tooth 9, and the upper right retaining tooth 8 and the lower right retaining tooth 9 are intersected. The lower left retaining tooth 7 and the lower left retaining tooth 7 are internally threaded with positioning bolts 17. The lower left retaining tooth 7, the lower left retaining tooth 7, the upper right retaining tooth 8, and the lower right retaining tooth 9 are internally provided with positioning holes 12, and the positioning bolts 17 are located inside the positioning holes 12.

[0024] Specifically, the upper left retaining tooth 6 of the upper pipe clamp ring 1 and the lower left retaining tooth 7 of the lower pipe clamp ring 2 are arranged in an alternating pattern to form an interlocking structure. Similarly, the upper right retaining tooth 8 and the lower right retaining tooth 9 adopt the same alternating design to ensure that the pipe clamp ring generates a self-locking effect in the circumferential direction (around the pump pipe direction). Furthermore, each retaining tooth has a positioning hole 12 at its root. The positioning bolt 17 passes through the upper and lower retaining teeth to fix the retaining teeth, further enhancing the connection and fixation of the pipe clamp on the pump pipe.

[0025] Working principle: The pump pipe end face is locked by fixing bolt 13 and nut 14 to prevent axial separation. The upper pipe clamp ring 1 and the lower pipe clamp ring 2 are clamped by fixing bolt 24 and fixing nut 25 to form a circumferential pressure seal. The upper left clamping teeth 6, the lower left clamping teeth 7, the upper right clamping teeth 8, and the lower right clamping teeth 9 are interlocked and reinforced by positioning bolt 17 penetrating through the root of the clamping teeth. The triple locking works together. The left protective plate 3 and the right protective plate 15 extend the pipe clamp coverage length to form a continuous protective surface, preventing mud from directly contacting the connector, improving the leak-proof capability, and ensuring the fixation and connection of the pipe clamp.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
