The hydraulic end connecting plate and the crosshead box connecting plate are fastened by a support sleeve. The fracturing pump spacer frame further includes a leg. The hydraulic end connecting plate, the crosshead box connecting plate, the support sleeve, and the leg are integrally formed. The leg includes a first vertical supporting plate and a second vertical supporting plate that are vertically disposed and a first bottom supporting plate that is horizontally disposed. The first vertical supporting plate is located below the hydraulic end connecting plate. The second vertical supporting plate is located below the crosshead box connecting plate. Two sides of the first bottom supporting plate are respectively connected to lower ends of the first vertical supporting plate and the second vertical supporting plate. In the present disclosure, an integrally formed fracturing pump spacer frame is used, to avoid an impact of a welding defect on stiffness, strength, service life, and the like. An approximately U-shaped leg may support both a hydraulic end connecting plate and a crosshead box connecting plate, so that the number of support points is increased, a moment and a caused deformation are decreased, and service life is increased. ## Claims ### Claim 1 A fracturing pump spacer frame, comprising: a hydraulic end connecting plate;
