Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the following embodiments are not intended to limit the scope of the present invention, and all equivalent substitutions and modifications made according to the contents of the present specification are within the technical scope of the present invention claimed in the present application.
Referring to fig. 1 and fig. 2 in combination, the lifting and pumping tool is used for pumping operation of a marine diesel piston, and has dual functions of lifting and pumping; the lifting pump pressure tool comprises a pump pressure seal plate member 1 and a lifting block 2.
The pumping pressure seal plate 1 is a rectangular steel plate, four corners of the pumping pressure seal plate are provided with mounting through holes 14 for being mounted on the piston through bolts, and two sides of the center of the pumping pressure seal plate are provided with a through oil inlet hole 11 and an oil outlet hole 12 for being connected with an oil inlet pipe and an oil outlet pipe respectively. The lower plane of the pumping pressure sealing plate 1 is provided with a sealing groove 13 for installing a sealing ring so as to prevent oil leakage during pumping pressure.
Referring to fig. 3 and 4, the lifting block 2 is cube-shaped, and a threaded hole 21 is formed in the center of the lifting block for installing a lifting bolt of a lifting appliance during piston lifting.
The utility model discloses a use as follows:
referring to fig. 5, the hoist pump tool is mounted on a piston; the oil inlet hole 11 and the oil outlet hole 12 on the pumping pressure sealing plate 1 are respectively aligned with the inlet and outlet holes of the oil path on the piston, the lower plane of the pumping pressure sealing plate 1 is attached to the piston to ensure complete attachment, the mounting through holes 14 on the four corners are corresponding to the holes on the piston, after the attachment surface is adjusted, the attachment surface is tightened by bolts, and the sealing condition of the attachment surface is checked.
Connecting the hoisting block 2 with a hoisting ring screw of a hoisting sling through a threaded hole 21, screwing the hoisting block and the hoisting ring screw, slowly hoisting the piston, and hoisting the piston into a pump pressure test area; after the piston reaches a pumping pressure test area, an oil inlet pipe, an oil outlet pipe and a stop valve are installed on the pumping pressure sealing plate 1, and then a pumping pressure test can be carried out. And repeating the steps, and sequentially hoisting all the pistons for a pump pressure test.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All equivalent changes and modifications made according to the contents of the present invention should be considered as the technical scope of the present invention.
