[0032] Example

[0033] like Figures 1-6 As shown, the auxiliary tool for the plunger pump disc pump includes a handle 1, an extension rod 2 connected to the middle of the handle 1, and two detachable sleeve replacement heads 7 installed at the ends of the extension rod 2; the ends of the two sleeve replacement heads 7 are respectively connected to a hexagonal head 8 and a square head 9, and the hexagonal head 8 and the square head 9 can be adapted to different large wheels on site.

[0034] The working mechanism of the plunger pump disc pump auxiliary tool provided in this embodiment is as follows:

[0035] Handle 1 is the main body of the tool, ensuring stable force application by the operator. Extension rod 2 connects handle 1 and socket change head 7, and its length can be customized to adapt to pump bodies of different heights or workspace limitations. The design of extension rod 2 allows the operator to operate without direct contact with the pump body, improving safety and convenience. The socket change head 7 is designed to be detachable, facilitating the replacement of different shaped heads according to different work requirements. The modular design greatly enhances the tool's flexibility and versatility. Hexagonal head 8 is suitable for use with hexagonal pump components, such as large wheel shafts, achieving disc pumping through rotation. Square head 9 is designed for pump components with square cross-sections. The design ensures a tight fit between the tool and its components, effectively transmitting force. By changing different socket heads, this tool can adapt to various pump bodies and components, reducing reliance on multiple specialized tools. It is easy to hold and operate, alleviating the operator's workload. It can quickly adapt to different working environments and task requirements, reducing tool change time and improving maintenance efficiency. The extension rod 2 design allows the operator to stay away from potentially hazardous mechanical areas, reducing the risk of accidental injury. This tool utilizes scrap pipe materials within the station, which are developed through drawing and improvement, and then welded to reduce material costs. It is universally applicable in gathering and transportation stations and fire and explosion-proof areas, aiming to reduce labor intensity and improve work efficiency.

[0036] Among the optional methods in this embodiment, the more preferred one is:

[0037] The handle 1 is ring-shaped, and a connecting block 3 is provided in the middle of the handle 1. The extension rod 2 is connected to the connecting block 3.

[0038] The ring-shaped design of handle 1 makes it more ergonomic and provides a better grip. Whether operating with one or two hands, it ensures that the operator can hold handle 1 firmly, reducing hand fatigue. The ring-shaped handle 1 also provides enough space for the operator to adjust the position of their fingers as needed to adapt to different operating forces and directions. The connecting block 3 is the connecting component between handle 1 and extension rod 2. It is made of sturdy materials to ensure that it can withstand the transmitted torque and force. The connecting block 3 can also be designed to be adjustable so that the length or angle of extension rod 2 can be adjusted as needed, further improving the tool's flexibility.

[0039] Among the optional methods in this embodiment, the more preferred one is:

[0040] The handle 1 is internally connected to a first link 4, which is connected to the connecting block 3.

[0041] The first link 4 serves as an internal connector between the handle 1 and the connecting block 3, transmitting force and torque. The material and strength of the first link 4 should match those of the handle 1 and the connecting block 3 to ensure that it can withstand various forces and stresses during operation.

[0042] Among the optional methods in this embodiment, the more preferred one is:

[0043] A second link 5 is connected between the extension rod 2 and the handle 1. The second link 5 and the first link 4 are located in the same vertical plane.

[0044] The second link 5, as the connecting part between the extension rod 2 and the handle 1, together with the first link 4, forms a stable support structure. Arranging both the first link 4 and the second link 5 in the same vertical plane helps to reduce the interference of lateral forces and torques, making the tool more stable and reliable during operation.

[0045] Among the optional methods in this embodiment, the more preferred one is:

[0046] There are three first links 4 and three second links 5, and the three first links 4 and the three second links 5 are arranged in a circular array on the extension rod 2.

[0047] The design incorporates three first connecting rods 4 and three second connecting rods 5 arranged in a circular array on the extension rod 2. This design further enhances the structural strength and operational stability of the plunger pump disc pump auxiliary tool. The three first connecting rods 4 and the three second connecting rods 5 are arranged in a circular array around the axis of the extension rod 2. This arrangement makes the force transmission more uniform and stable. Each connecting rod bears a portion of the force and torque, which is distributed throughout the structure through the circular array, thereby improving the tool's load-bearing capacity and durability.

[0048] Among the optional methods in this embodiment, the more preferred one is:

[0049] There is an angle between the first link 4 and the second link 5, and the angle is 45 degrees.

[0050] The angle between the first link 4 and the second link 5 is set at 45 degrees, which has good performance in terms of structural mechanics. It can provide stable support and balance when transmitting force. The 45-degree angle also makes the connection between the links more compact, reducing the overall size and weight of the tool and improving portability and flexibility.

[0051] Among the optional methods in this embodiment, the more preferred one is:

[0052] The end of the extension rod 2 is connected to a square male buckle 6, and both sleeve replacement heads 7 are provided with buckle grooves 71 that mate with the square male buckle 6.

[0053] The square male buckle 6 is fixed to the end of the extension rod 2. Its square shape provides good anti-rotation performance and ensures the stability of the connection. Both socket replacement heads 7 are provided with buckle grooves 71 that match the square male buckle 6. The shape and size of the buckle grooves 71 match the square male buckle 6, so that the two can be easily connected and locked. The design of the buckle grooves 71 takes into account the need for quick replacement, so that the operator can quickly connect the socket replacement head 7 to the extension rod 2 or remove it from the extension rod 2, which improves work efficiency.

[0054] Among the optional methods in this embodiment, the more preferred one is:

[0055] The outer wall of handle 1 is provided with anti-slip texture.

[0056] The anti-slip texture design significantly reduces accidental slippage caused by tool slippage, lowering safety risks during operation. The increased friction allows the operator to grip the handle 1 more stably during operation, reducing the possibility of hand slippage and improving operational accuracy and efficiency. The anti-slip texture design can cope with different working environments and conditions, such as wet, oily, and cold conditions, ensuring good anti-slip performance under various circumstances. The stable grip reduces wear and damage to the handle 1 caused by frequent changes in grip or adjustment of tool position, thereby extending the tool's service life.

[0057] Among the optional methods in this embodiment, the more preferred one is:

[0058] The square male buckle 6 has angled edges on all four sides of its top surface.

[0059] The tilt angle serves as a guide, making the square male buckle 6 insert into the buckle slot 71 more smoothly and reducing wear or damage caused by misalignment.

[0060] Among the optional methods in this embodiment, the more preferred one is:

[0061] The square male buckle 6 and the buckle groove 71 are fitted with a clearance.

[0062] The clearance fit allows the square male buckle 6 to be easily inserted into the buckle groove 71 without the need for additional tools or excessive force, thus improving assembly efficiency. Due to the certain clearance, the square male buckle 6 and the buckle groove 71 can tolerate certain dimensional and shape errors, enhancing the adaptability and reliability of the fit. The clearance fit reduces wear caused by friction and extends the service life of the parts. When disassembly is required, the clearance fit allows the square male buckle 6 to be easily removed from the buckle groove 71, reducing disassembly difficulty and time. In addition, when designing the clearance fit, the size of the clearance needs to be reasonably determined. If the clearance is too large, it may cause the fit to loosen, affecting the stability of the connection; if the clearance is too small, it may increase assembly difficulty and wear.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
