The frame assembly 1 is an integral support structure, including a front frame 11, a rear frame 12, and a base plate 13. The base plate 13 is fixedly installed on the upper end of the front frame 11 by bolts. The rear frame 12 is fixedly connected to one end of the front frame 11 by welding to form a stable frame structure. A guide wheel assembly 9 is installed on one side of the front frame 11, which can flexibly adjust the direction of equipment movement. A trailer brake coupler 10 is also fixedly installed on the upper end of the front frame 11, which facilitates connection with external traction equipment and has a braking function to improve safety during movement.
[0015] like Figures 1 to 2As shown, the transmission assembly 2 includes a power input shaft 21, a transmission shaft 22, a first transmission wheel 23, a second transmission wheel 24, a transmission belt 25, a connecting shaft 26, and a power output shaft 27. A shaft mounting plate 28 is fixedly installed on the lower end of the base plate 13 with screws. The power input shaft 21 passes through the shaft mounting plate 28 and is precisely connected to one end of the transmission shaft 22 via a coupling. The connecting shaft 26 is fixedly connected to the other end of the transmission shaft 22 and passes through the center hole of the first transmission wheel 23. The transmission belt 25 is tensioned and connected between the first transmission wheel 23 and the second transmission wheel 24. The power output shaft 27 is fixedly connected to the second transmission wheel 24, and the other end of the power output shaft 27 is connected to the input end of the centrifugal pump assembly 4, achieving stable power transmission. To elaborate further, such as Figure 1 As shown, a first fixing plate 14 and a second fixing plate 15 are fixedly installed in the rear frame 12.
