Description

Technical Field

[0001] This invention relates to the field of pump maintenance and repair, specifically to a fracturing pump packing replacement device. Background Technology

[0002] With the large-scale exploitation of shale gas, shale gas well platform operations are characterized by multiple construction layers, large displacement, and large single-layer construction fluid volume. A single platform requires multiple fracturing trucks to operate simultaneously. During the disassembly and assembly of the fracturing pump plunger packing, manual disassembly and assembly operations are often performed using tools such as screwdrivers and copper rods. However, due to the limited space, packing replacement is difficult, inconvenient, and may damage the inner wall of the equipment.

[0003] Currently, the replacement of packing material used in fracturing operations still requires manual labor using various tools, which is time-consuming and costly. Therefore, to address these issues, a device for the installation and removal of packing material in fracturing pumps needs to be designed to achieve stable installation of the packing material and rapid recovery of damaged packing material. Summary of the Invention

[0004] This invention provides a fracturing pump packing replacement device that is simpler to operate and more efficient, in order to solve the problem of cumbersome replacement and maintenance of fracturing pump plunger packing, which is time-consuming and labor-intensive, as mentioned in the background art.

[0005] The technical solution adopted in this invention is: to provide a fracturing pump packing replacement device, comprising: The main rod has a threaded hole at the upper end, which is connected to the locking ring (1). A rectangular through hole is provided inside to install the spring locking component. A threaded hole is provided at the lower end to connect with the mounting fastener. A rectangular long slot is provided on the outer side to install the rack. The drive wheel has drive wheel support columns on both sides, which are connected by locking components. The lower end has a threaded hole on the toothless surface, which connects to the power rod. The disc support frame has a threaded hole on its upper end face to connect with the bracket ring, and the lower end face of the disc support frame also has a thread to connect with the side support column. A circular hole is provided in the center to fix the main body rod. The side support column has a threaded hole at the bottom for connection with the side locking component; The base has an internal annular groove that engages with the side locking mechanism for secure connection. The component can be replaced; the upper end is provided with a threaded hole for connection with the mounting fastener. The upper end cover has threads on the upper surface for connection with mounting fasteners, and threaded holes on the lower end for connection with the replacement chassis. The locking slider has a round hole groove on its side end face for installing a spring; The chassis clamps the slider, and the lower end is provided with a threaded hole for connection with the adjustment knob.

[0006] Furthermore, both the disc support frame and the bracket ring have circular through holes at their centers to fix the main body rod.

[0007] Furthermore, the connection area between the drive wheel support column and the locking member is adjustable, allowing the installation position of the drive wheel to be changed according to the rack position.

[0008] Furthermore, the side locking member can slide on the groove of the chassis.

[0009] Furthermore, the rack meshes with the drive wheel, adjusting the height of the device.

[0010] Furthermore, the upper end face of the clamping slider is provided with a circular hole, and the spring is locked in position by a spring locking component.

[0011] Compared to traditional fracturing pump packing replacement devices, this invention significantly simplifies manual operation by introducing a power rod and utilizing a gear transmission mechanism to achieve the downward pressing action. Furthermore, this invention cleverly incorporates a spring assembly at the chassis; when the spring locking element is raised, the inclined clamping slider automatically pops out, thus automatically clamping the packing. Based on this, the power rod is used to complete the removal or installation of the packing. This invention not only further reduces the complexity of manual operation but also improves the automation level of the entire installation process, effectively simplifying the packing replacement process and significantly improving work efficiency.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Example: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A fracturing pump packing replacement device includes a locking ring 1 with a threaded connection hole for connection to a main body rod 2; a slot on the side of the main body rod 2 for mounting a rack 11; a sliding groove inside the main body rod 2 for locking with a spring locking member 15; a threaded front end of a power rod 6 for connection to a threaded hole at the bottom of a drive wheel 3; the drive wheel 3 meshing with the rack 11; a circular hole in the middle of a disc support member 13 and a bracket ring 14; and an arc-shaped sliding groove on a base 8 for locking with a side locking member 12.

[0017] In this embodiment, both the disc support 13 and the bracket ring 14 have circular through holes in the middle for smooth longitudinal movement of the main body rod 2; the end of the power rod 6 has a cylindrical gripping part for convenient on-site use. The drive wheel 3, which is threaded at the front end, meshes with the rack 11 to control the longitudinal movement of the main body rod 2; the base 8 has an arc-shaped sliding groove, allowing the power rod 6 to rotate circumferentially when installing filler, facilitating multi-directional installation.

[0018] Furthermore, in some implementations of this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the outer diameter of the base 8 is slightly larger than the outer diameter of the plunger cylinder; the main rod 2 is fixed to the upper end face of the upper cover 901 by the mounting fastener 10 through threaded engagement; the replacement assembly 9 is provided with two clamping sliders 904, which are installed symmetrically; the side end face of the clamping slider 904 is provided with mounting holes for installing springs 902; one end of the spring locking member 15 is provided with two cylindrical pins, which cooperate with the insertion holes provided on the upper end of the clamping slider 904.

[0019] In this embodiment, the base 8 is slightly larger than the outer diameter of the plunger cylinder and is installed close to the outer end face of the plunger cylinder; the lower cylindrical pin of the spring locking member 15 is locked in the upper mounting hole of the locking slider 904, the spring 902 is contracted, and the locking slider 904 is in a retracted state; the power rod 6 is continuously pressed down, and the drive wheel 3 connected to the front end meshes with the rack 11 to realize the longitudinal displacement of the main body rod 2; the bottom replacement component 9 moves synchronously under the action of the main body rod 2 to reach the designated replacement position.

[0020] Furthermore, in some implementations of this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the chassis 904 has sliding grooves at both ends, and the chassis is installed by clamping the slider 905. The lower end of the slider has a threaded hole, and the adjustment knob 906 is connected by a threaded fit.

[0021] In this embodiment, after the chassis 9 is removed and placed at the designated installation position, the spring fastener 15 on the upper end of the main body rod 2 is pulled up, causing the cylindrical pin at the lower end of the spring fastener 15 to disengage from the insertion hole on the upper end of the clamping slider 904.
