Description

Technical Field

[0001] The utility model relates to the technical field of petroleum equipment, in particular to a hydraulic end packing assembly tool. Background Art

[0002] The seals in the hydraulic end of a fracturing pump play a crucial role, and their fragility necessitates regular replacement. The rapid reciprocating motion of the plunger during hydraulic end operation wears the seal packing. To ensure effective sealing, the packing needs to be replaced regularly. However, installation of new packing and gaskets can be difficult due to the limited size of the mounting holes and uneven force applied during manual installation. Improper handling can even damage the inner wall of the pump head, compromising the sealing effect.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Utility Model Content

[0004] In view of the above-mentioned deficiencies and defects of the packing assembly device in the prior art, in order to achieve the above-mentioned purpose, the utility model provides a hydraulic end packing assembly tool, comprising:

[0005] An adjusting plate is provided with a follower plate in the middle of the adjusting plate, the adjusting plate and the follower plate are rotationally connected, and an assembly plate is provided at the other end of the follower plate, the follower plate and the assembly plate are rotationally connected.

[0006] As a preferred technical solution, the follower plates are symmetrically arranged in pairs, adjacent follower plates are arranged in parallel, and a rectangular structure is formed between the follower plates, the adjustment plates and the assembly plate.

[0007] As described above, the hydraulic end packing assembly tool provided by the present invention has the following beneficial effects:

[0008] The utility model provides an adjustment plate, a follower plate, and an assembly plate. The two ends of the paired follower plates are rotatably mounted in the middle of the adjustment plate and the assembly plate, and a rectangular structure is formed between the adjustment plate, the follower plate, and the assembly plate. The device has a simple structure and low manufacturing cost. It can install the sealing parts in a limited manner, avoids damage to the packing and the inner wall caused by manual assembly of the packing, and does not affect the sealing performance of the packing. The use of a packing assembly tool reduces the assembly difficulty and increases work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0013] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Although the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation, the form, quantity, positional relationship and proportion of each component in actual implementation can be changed at will under the premise of realizing the technical solution of this party, and the component layout form may also be more complicated. Example

[0014] This embodiment provides a hydraulic end packing assembly tool, refer to the attached Figure 1 The device includes an adjusting plate 1, a following plate 2 is provided in the middle of the adjusting plate 1, the following plates 2 are arranged in pairs and in parallel, and are symmetrical about the middle of the adjusting plate 1, the following plate 2 is rotationally connected to the adjusting plate 1, and an assembly plate 3 is provided on the other side of the following plate 2, the front end and the two sides of the assembly plate 3 are wedge-shaped, and the assembly plate 3 is rotationally connected to the following plate 2. Preferably, the connection method in this embodiment is a bolt connection; in addition, the following plates 2 are arranged in pairs and are symmetrical along the middle of the assembly plate 3, and a rectangular structure is formed between the following plate 2, the adjusting plate 1 and the assembly plate 3.

[0015] Refer to the attached Figure 2 When using this device, put the packing into the mounting hole and ensure coaxiality, rotate the adjustment plate 1 to drive the follower plate 2 to move. At this time, the inclination angle of the assembly plate 3 is consistent with that of the adjustment plate 1, and the wedge surface fits the packing. Rotate the adjustment plate 1 again to make the assembly plate 2 perpendicular to the follower plate 2, and install the packing in the corresponding position.

[0016] In summary, the present invention provides an adjustment plate, a follower plate, and an assembly plate. The two ends of the paired follower plates are rotatably mounted in the middle of the adjustment plate and the assembly plate, respectively. A rectangular structure is formed between the adjustment plate, the follower plate, and the assembly plate. This device has a simple structure and low manufacturing cost.
