Description

Technical Field

[0001] The present application relates to the field of plunger pump disassembly and assembly tools, and in particular to a plunger pump disassembly and assembly tool. Background Art

[0002] Various types of plunger pumps are the main equipment used in oil fields. They are mainly used in oil field production, water injection, and well repair operations to perform high-pressure construction tasks such as well washing, sand control, acidification, and pressure testing. Regular maintenance of plunger pumps is the key to ensuring their technical performance and working ability. For example, during the construction of sand control plunger pumps, the working conditions are harsh. The plunger seal components are easily worn under the action of sand particles, acid and other highly frictional and corrosive working media and the high number of plunger strokes. The preload force is reduced, causing the plunger to leak, and the working efficiency is reduced, affecting the normal operation of the plunger.

[0003] The existing Chinese public patent (authorization announcement number: CN220145804U) mentions that by using a bolt removal tool with one-way cooperation between a gear and a pawl, the one-way rotation restriction on the bolt sleeve component can be released, and the bolt sleeve component can be driven to rotate by a manual handle from the end of the handle, so that there is no need to put the hand into the shell, and the bolts can be continuously and quickly unscrewed from the packing box, which has the effect of improving the removal efficiency.

[0004] Although the technical solution of the above document has the characteristics of not having to put hands into the shell and being able to continuously and quickly unscrew the bolts from the packing box, the defects it brings are also more obvious. For example, when the disassembly and assembly personnel need to disassemble and assemble the plunger pump, the sizes of the external and internal bolts of the plunger pump are different, and the disassembly and assembly tools lack the function of adjusting the size of the disassembly and assembly bolt parts during disassembly and assembly, resulting in the need for disassembly and assembly personnel to change tools in different occasions, which increases the cumbersomeness of the operation. Utility Model Content

[0005] The purpose of the present application is to solve the problem that it is difficult for maintenance personnel to adjust the size of bolts, and the present application provides a plunger pump disassembly and assembly tool.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A plunger pump disassembly and assembly tool comprises a shell, one end of the shell is rotatably connected to a rotating cylinder via a first bearing, the other side of the rotating cylinder is rotatably connected to a handle via a second bearing, a connecting rod is fixedly connected to the middle of one end of the rotating cylinder, one end of the connecting rod is fixedly connected to a positioning plate, an adjustment mechanism is provided on the surface of the positioning plate, a pry bar assembly is provided inside the handle, a positioning assembly is provided on one side of the adjustment mechanism, and a lighting mechanism is provided on one side of the shell.

[0013] Furthermore, the pry bar assembly includes a handle with a cavity formed inside, sliding blocks are slidably connected to both sides of the handle surface, and a pry bar is fixedly connected to one side of the sliding block.

[0017] Furthermore, the lighting mechanism includes a lighting lamp disposed on one side of the housing, and a battery is disposed inside the lighting lamp.

[0021] Furthermore, an auxiliary sliding block is provided on one side of the back side of the special-shaped block, and the surface of the auxiliary sliding block is slidably connected to the inside of the hexagonal sliding groove plate.

[0033] The embodiment of the present application discloses a plunger pump disassembly and assembly tool.

[0034] Reference Figure 1 A plunger pump disassembly and assembly tool comprises a shell 1, one end of the shell 1 is rotatably connected to a drum 2 through a first bearing, the other side of the drum 2 is rotatably connected to a handle 4 through a second bearing, a connecting rod 5 is fixedly connected to the middle of one end of the drum 2, one end of the connecting rod 5 is fixedly connected to a positioning plate 6, an adjusting mechanism 7 is arranged on the surface of the positioning plate 6, a pry bar assembly is arranged inside the handle 4, a positioning assembly is arranged on one side of the adjusting mechanism 7, and a lighting mechanism is arranged on one side of the shell 1.

[0035] When the disassembly tool is in use, the maintenance personnel can hold the shell 1 and, according to the size of the disassembly nut, rotate the adjusting piece 12 counterclockwise to drive the hexagonal slide plate 8 to rotate counterclockwise, so that the special-shaped block 9 can slide along the hexagonal slide plate 8 and the auxiliary frame 11 through the slider 10 and the auxiliary slider, so that the special-shaped block 9 begins to expand and adjust to the appropriate size. At the same time, the maintenance personnel can use the positioning plug rod 13 to clamp it into the inside of the appropriate hole so that the special-shaped block 9 can be limited. When the special-shaped block 9 clamps the disassembly nut, the maintenance personnel can hold the shell 1 with one hand and the rotating drum 2 with the other hand to rotate, so that the rotating drum 2 drives the connecting rod 5 to rotate while quickly disassembling and assembling the disassembly nut. When the maintenance personnel are disassembling and assembling in a dimly lit place, they can use a lighting lamp to illuminate the disassembly and assembly part, thereby improving the disassembly and assembly efficiency of the maintenance personnel.

[0036] Reference Figure 2 and Figure 3 The adjusting mechanism 7 includes a positioning plate 6, which is rotatably connected to a hexagonal slide plate 8 on the front side, and a plurality of special-shaped blocks 9 are slidably connected inside the hexagonal slide plate 8.

Holes that are compatible with the positioning rod 13 are equidistantly opened on the top surface of the positioning plate 6.

[0037] During the use of the disassembly and assembly tool, the maintenance personnel can rotate the adjusting piece 12 counterclockwise according to the actual size of the disassembly and assembly nut, driving the hexagonal slide plate 8 to rotate counterclockwise, so that the special-shaped block 9 can slide along the hexagonal slide plate 8 and the auxiliary frame 11 through the slider 10 and the auxiliary slider, so that the special-shaped block 9 begins to expand.
