Description

Technical Field

[0001] The utility model relates to the technical field of pump plunger processing, in particular to a heat treatment tool for a plunger pump plunger of a fracturing vehicle. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. The plunger pump is widely used in high pressure, large flow and flow regulation occasions, such as hydraulic presses, engineering machinery and ships.

[0003] At present, the existing technology adopts that the hook of the lifting equipment is directly hooked at the edge of the material frame to hang the material frame; this method has two disadvantages. One is that the worker is easy to be accidentally scalded when hooking the material frame.

[0004] For example, a plunger heat treatment tool disclosed in Chinese patent CN217199244U has a rectangular bottom plate as a whole, and multiple push rods are welded on the bottom plate. The height of the push rods is slightly higher than the length of the plunger. The multiple push rods are evenly arranged on the bottom plate, and the center of the push rods is staggered at 45 degrees. Through holes are opened at the four corners and the center of the bottom plate. After the screws pass through the through holes, support tubes are screwed on. The height of the support tube is greater than the height of the push rods. Notches with a width greater than the width of four fingers of a human hand are opened inward on the short sides of both sides of the bottom plate, and handles are welded on the bottom plate to bridge the gaps. Compared with the prior art, the utility model combines the heat treatment tool with the turnover facility, and the plunger gaps are equal, and the heat treatment effect is consistent. At the same time, it can avoid collisions between plungers, facilitate counting, and improve efficiency.

[0005] However, the plunger heat treatment tool lacks an ejection quick-takeout mechanism for taking out the plunger after the plunger is heat treated, which reduces the processing efficiency of the plunger to a certain extent.

[0006] To this end, we proposed a heat treatment tool for the plunger of the fracturing truck plunger pump to solve the above problems. Utility Model Content
