Description

Technical Field

[0001] The utility model relates to the technical field of marine fuel pumps, and particularly relates to a tooling for an inverted frame of a marine fuel pump. Background Art

[0002] Marine fuel pumps are special equipment designed for marine fuel systems. They play an important role in transporting fuel from fuel storage devices (such as fuel tanks) to engines or generators. They have characteristics such as large flow rate, high pressure, corrosion resistance, and reliable durability to meet the fuel supply requirements of ships. In order to have a specific understanding of marine fuel pumps, it is necessary to understand the physical marine fuel pumps. Currently, for the display of marine fuel pumps, most are directly displayed by hoisting. However, due to the large mass of the marine fuel pump itself, it cannot be fixed by manpower, which will cause the fuel pump to shake. This not only has low safety but also is inconvenient for maintenance and disassembly, and thus the intuitive display of marine fuel pumps cannot be achieved. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a tooling for an inverted frame of a marine fuel pump, which can achieve the intuitive display of the marine fuel pump, has high safety, and is convenient for maintenance and disassembly.

[0004] The utility model adopts the following technical scheme. A tooling for an inverted frame of a marine fuel pump includes a frame and auxiliary clamps. The frame is U-shaped, and a speed reducer is installed on the frame. The auxiliary clamps include a left half-jaw and a right half-jaw. The left half-jaw and the right half-jaw have the same structure, and both include a clamping part with a semi-circular cross-sectional shape. The clamping parts of the left half-jaw and the right half-jaw form a clamping area. Locking holes for installing stud bolts are provided at the upper and lower ends of the left half-jaw and the right half-jaw. After the fuel pump is clamped in the clamping area by the clamping parts of the left half-jaw and the right half-jaw, it is locked by the cooperation of the stud bolts and the locking holes. Shaft grooves are provided at the left and right ends of the left half-jaw and the right half-jaw. One end of a connecting shaft is assembled and connected in the shaft grooves, and the other end of the connecting shaft is connected to a coupling. The coupling is installed on the frame, and the speed reducer is connected to one side of the coupling.

[0005] Further, the connecting shaft is cross-shaped. The left and right ends of the connecting shaft are respectively assembled and connected to the coupling and the shaft grooves. Screw holes are provided at the upper and lower ends of the connecting shaft, and bolts pass through the screw holes to connect the connecting shaft to the left half-jaw or the right half-jaw.

[0006] Further, the frame includes a base. Columns are installed at both ends of the base, and a support beam is installed on the columns. The auxiliary clamps are located between the two support beams at both ends.

[0007] Further, an anti-slip and wear-resistant pad is provided on the clamping surface of the clamping part.

[0008] Furthermore, clamping teeth are provided on the clamping surface of the clamping part.

[0009] The beneficial effects of the utility model are that the marine fuel pump can be clamped and fixed on the frame through the left half-jaw and the right half-jaw, and can be placed at any angle by rotating through the speed reducer, so that it can be conveniently and safely fixed in a certain position, which is convenient for display and disassembly, and has good use value.
