Abstract
Description
Technical Field
[0001] This utility model relates to the field of axial flow pump technology, and in particular to a hydraulic axial flow pump. Background Technology
[0002] A hydraulic axial flow pump is a type of horizontal axial flow pump, typically composed of components such as an impeller, pump casing, shaft, and bearings. The impeller is the core component of the axial flow pump; when the impeller rotates, the liquid is drawn in and accelerated, and then discharged. The pump casing serves to fix and guide the liquid.
[0003] A search revealed that utility model patent CN213838915U discloses a vertical shaft axial flow pump, which includes a vertical shaft wall. Two sets of support plates are symmetrically cast and fixed on the side wall of the vertical shaft wall. A limiting groove is opened on the top of the support plate, and a support column is engaged in the inner cavity of the limiting groove. An axial flow pump body is welded between the two sets of support columns. Lifting lugs are symmetrically welded on the top of the axial flow pump body, and a connecting block is welded to the bottom of the axial flow pump body at the end away from the support column.
[0004] However, the above-mentioned axial flow pump still has some drawbacks in actual use. The most obvious one is that when supporting the front end of the axial flow pump body, in order to ensure the support effect and prevent the fixed plate from moving during the support process, the operator still needs to perform a cumbersome operation to fix the fixed plate, which is too inconvenient in actual use.
[0005] Therefore, it is necessary to invent a hydraulically driven cross-flow pump to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a hydraulic axial flow pump that can conveniently support the front end of the axial flow pump body. It has a simple structure, is easy to use, and has better practical performance. This solves the problem mentioned in the background art that, in order to ensure the support effect and prevent the fixed plate from moving during the support process, the operator still needs to perform cumbersome operations to fix the fixed plate, which is too inconvenient in actual use.
[0007] According to one aspect of this disclosure, the following technical solution is provided: a hydraulically driven axial flow pump, comprising:
[0008] Shaft wall, which is used to install the rear support mechanism;
[0009] A rear support mechanism is provided for installing and supporting the rear end of the axial flow pump assembly.
[0010] Axial flow pump assembly; and
[0011] A front-end support mechanism, comprising an outer ring, an extension shaft, a support arm, a limiting groove, a locking pin, and a return spring;
[0012] The outer sleeve is fixedly sleeved on the front end of the outer side of the axial flow pump body. The extension shaft is rotatably nested on the side of the outer sleeve through a bearing. The support arm is fixedly inserted through the end of the extension shaft. The limiting groove is opened at the bottom end of the L-shaped support plate. The locking pin is slidably inserted through the side of the L-shaped support plate and extends to the inside of the limiting groove. The reset spring is sleeved on the outside of the locking pin and fixedly connected between the L-shaped support plate and the locking pin.
[0013] According to at least one embodiment of the hydraulic cross-flow pump of the present disclosure, the rear support mechanism includes two sets of support components, each set of support components including an L-shaped support plate and a receiving groove.
[0014] According to at least one embodiment of the hydraulically driven axial pump of the present disclosure, the L-shaped support plate is fixedly connected to the shaft wall, and the receiving groove is formed on the top of the L-shaped support plate.
[0015] According to at least one embodiment of the present disclosure, the hydraulically driven axial flow pump assembly includes an axial flow pump body located between two L-shaped support plates.
[0016] According to at least one embodiment of the hydraulic axial flow pump of the present disclosure, the axial flow pump assembly further includes two support columns, which are respectively fixedly disposed on both sides of the axial flow pump body and located inside two receiving grooves.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] This invention features a front-end support mechanism. After the axial flow pump assembly is placed using hoisting equipment, the support arm rotates around the extension shaft. During rotation, the locking pin is pulled outward, stretching the return spring and causing it to move out of the limiting groove. When the support arm enters the limiting groove and its end contacts the inner wall, the locking pin is released, and the stretched return spring resets the locking pin, preventing the support arm from slipping out of the limiting groove. Compared to existing devices of the same type, this invention provides more convenient support for the front end of the axial flow pump body, has a simple structure, is easy to use, and offers better practical performance.

[0028] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0029] Figure 1 This is a schematic diagram of the overall structure of a hydraulically driven cross-flow pump according to one embodiment of the present disclosure.
[0030] Figure 2 This is a partial structural diagram of the rear support mechanism 2 and the front support mechanism 4 of a hydraulic cross-flow pump according to one embodiment of the present disclosure.
[0031] Figure 3This is a partial structural diagram of the axial pump assembly 3 and the front-end support mechanism 4 of a hydraulic axial pump according to one embodiment of the present disclosure.
[0032] like Figures 1-3 As shown, the hydraulically driven axial flow pump disclosed herein may include components such as: shaft wall 1, rear support mechanism 2, axial flow pump assembly 3, and front support mechanism 4.
[0033] like Figure 2 As shown in this disclosure, the rear support mechanism 2 includes two sets of support components. Each set of support components includes an L-shaped support plate 21 and a receiving groove 22. The L-shaped support plate 21 is fixedly connected to the shaft wall 1, and the receiving groove 22 is opened at the top of the L-shaped support plate 21.
[0034] like Figure 3 As shown, in a preferred embodiment, the cross-flow pump assembly 3 includes a cross-flow pump body 31 and support columns 32. The cross-flow pump body 31 is located between two L-shaped support plates 21. Two support columns 32 are provided, and the two support columns 32 are respectively fixedly arranged on both sides of the cross-flow pump body 31. The two support columns 32 are respectively located inside the two receiving grooves 22.
[0035] Therefore, the axial flow pump body 31 can be lifted and moved using a suspension device until the two support columns 32 enter the inner side of the two receiving slots 22 respectively. At this time, the L-shaped support plate 21 supports the rear end of the axial flow pump body 31, and the receiving slots 22 limit the support columns 32 to prevent the axial flow pump body 31 from falling.
[0036] like Figure 2 and Figure 3 As shown in this disclosure, the front-end support mechanism 4 includes an outer ring 41, an extension shaft 42, a support arm 43, a limiting groove 44, a locking pin 45, and a return spring 46. The outer ring 41 is fixedly sleeved on the outer front end of the cross-flow pump body 31. The extension shaft 42 is rotatably nested on the side of the outer ring 41 via a bearing. The support arm 43 is fixedly inserted through the end of the extension shaft 42. The limiting groove 44 is opened at the bottom end of the L-shaped support plate 21. The locking pin 45 is slidably inserted through the side of the L-shaped support plate 21 and extends to the inside of the limiting groove 44. The return spring 46 is sleeved on the outside of the locking pin 45 and fixedly connected between the L-shaped support plate 21 and the locking pin 45.
[0037] Therefore, after the axial flow pump assembly 3 is placed using hoisting equipment, the support arm 43 is rotated around the extension shaft 42. During the rotation of the support arm 43, the locking pin 45 is pulled outward. After the locking pin 45 is pulled, the return spring 46 is stretched and moves out from the inside of the limiting groove 44. When the support arm 43 enters the inside of the limiting groove 44 and its end contacts the inner wall of the limiting groove 44, the locking pin 45 is released. The stretched return spring 46 drives the locking pin 45 to return to its original position, thereby preventing the support arm 43 from coming out from the inside of the limiting groove 44. Compared with existing similar devices, the support of the front end of the axial flow pump body 31 can be completed more conveniently. The structure is simple and easy to use, and the actual use effect is better.
