Plunger pump stopper block assembly

Abstract

This utility model discloses a plunger pump limiting block assembly, relating to the field of plunger pump technology. The device includes a plunger pump, a housing, and a pump body, with the pump body installed inside the housing. It also includes a fixing plate installed inside the housing, with two sets of fixing plates respectively engaging with both sides of the pump body. A second one-way screw is connected to the outer side of the fixing plate away from the pump body. The second one-way screw is connected to the surface of the fixing plate via a bearing, and the other end of the second one-way screw extends outward from the outer side of the housing through a threaded hole on the housing surface. The fixing plate clamps both sides of the pump body, securing it in place. Rotating a second handle rotates the second one-way screw, causing the fixing plate to move inward and secure the pump body. This allows for limiting the plunger pump during operation and also allows the pump body to be loosened by loosening the fixing plate during maintenance.

Description

Technical Field

[0001] This utility model relates to the field of plunger pump technology, specifically to a plunger pump limiting block assembly. Background Technology

[0002] With the continuous development of modern industry, piston pumps are widely used in applications requiring high pressure, large flow, and flow rate adjustment, such as hydraulic presses, engineering machinery, and ships, due to their high efficiency and easy flow rate adjustment.

[0003] For example, the announcement number CN215633727U is titled "A Plunger Pump with a Positioning Mechanism". The device includes a plunger pump body, and an outer shell is fitted around the outside of the plunger pump body. A mounting plate is fixedly connected to the right side of the outer shell by bolts. The mounting plate is fixedly connected to the right end of the plunger pump body. The elastic potential energy of the second spring drives the T-shaped block to slide out of the inner cavity, so that the magnetic block one and magnetic block two fixed to the T-shaped block attract and adhere to each other, further strengthening the fixing effect between the plunger pump body and the outer shell, and playing an auxiliary positioning role for subsequent installation and fixing. When the above-mentioned device is in use, the connection between the pump body and the outer casing is relatively loose, and the loose pump body will cause displacement and movement during operation. Utility Model Content

[0004] The purpose of this invention is to provide a plunger pump limiting block assembly to solve the problem mentioned in the background art, where the connection between the pump body and the outer shell is relatively loose, and the loose pump body will cause displacement during operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plunger pump limiting block assembly, comprising a housing and a pump body, wherein the pump body is installed inside the housing; Also includes: A fixing plate is installed inside the outer casing, and two sets of fixing plates are respectively engaged on both sides of the pump body. A second one-way screw is connected to the outer side of the fixing plate away from the pump body. The second one-way screw is connected to the surface of the fixing plate through a bearing. The other end of the second one-way screw extends out of the outer casing through a threaded hole on the surface of the outer casing, and the second one-way screw is threadedly connected to the threaded hole on the surface of the outer casing. A second handle is connected to the other end of the second one-way screw. A second clamping plate is provided on the inner wall of the outer casing, and the second clamping plate is engaged with the surface of the second one-way screw. A first clamping plate is provided on the outer wall of the outer casing, and the first clamping plate is engaged with the surface of the second one-way screw. Both the second clamping plate and the first clamping plate are provided in two sets and are symmetrically arranged on both sides of the second one-way screw.

[0006] Preferably, the outer shell surface is provided with a sliding groove, and there are two sliding grooves symmetrically arranged on both sides of the connection between the outer shell and the second one-way screw. The second clamping plate and the first clamping plate are connected by a slider, and the slider is slidably engaged inside the sliding groove.

[0007] Preferably, the outer shell is provided with a fixing frame, and two sets of fixing frames are symmetrically arranged and located on the upper and lower sides of the slide groove respectively. Side plates are symmetrically arranged at both ends of the first clamping plate. A bidirectional screw is installed between the upper fixing frames, and the side plates at the corresponding positions are threaded to the bidirectional screw through threaded holes on their surfaces. One end of the bidirectional screw is connected to a rotating handle.

[0008] Preferably, a sliding rod is installed between the lower fixing brackets, and the side plate at the corresponding position is slidably engaged with the sliding rod through a round hole on its surface.

[0009] Preferably, a limiting plate is installed inside the outer shell, and the limiting plate is located on both sides of the fixed plate. A limiting groove is provided on the side of the limiting plate near the fixed plate. Sliding blocks are symmetrically arranged on both sides of the fixed plate, and the sliding blocks are slidably engaged inside the limiting groove.

[0010] Preferably, a cover plate is installed on the upper end of the outer shell, a first one-way screw is connected to the upper surface of the cover plate, and the first one-way screw is threadedly connected to the threaded hole on the surface of the cover plate. A first handle is installed on the upper end of the first one-way screw, and a pressure plate is installed on the bottom end of the first one-way screw, and the pressure plate is attached to the upper surface of the pump body.

[0011] Preferably, a base pad is installed at the bottom of the inner part of the housing, and the upper end of the pump body is fixed to the surface of the base pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting a fixing plate inside the outer shell, the fixing plate is clamped on both sides of the pump body to lock and fix the pump body. By turning the second handle to drive the second one-way screw to rotate, the fixing plate moves inward to lock and fix the pump body. This can limit the operation of the plunger pump, and the pump body can also be loosened by loosening the fixing plate when the pump body is removed for maintenance.

[0013] (2) By rotating the handle to drive the bidirectional screw to rotate, the first clamping plate can engage and fix the two sides of the second one-way screw. The inner sides of the second clamping plate and the second clamping plate are provided with threaded holes with the same pitch as the surface of the second one-way screw. By using the threaded holes on the inner side of the clamping plate to engage with the threads on the surface of the second one-way screw, the second one-way screw is limited, thereby preventing the second one-way screw from rotating and causing the fixing plate to loosen.
