Description

Technical Field

[0001] This utility model belongs to the technical field of drive equipment installation structure, specifically relating to a pipeline pump base adjustment and fixing device. Background Technology

[0002] Inline pumps are commonly used pumping devices in liquid supply systems such as water supply systems. Their main function is to draw water from a lower elevation to a higher elevation. Inline pumps mainly consist of an impeller and a motor. When operating, the inline pump needs to be connected to a corresponding pipeline, and the motor outputs driving force to drive the water flow.

[0003] Currently, during the installation of pipeline pumps, after the pipeline pump is placed on the placement surface, there may be slight alignment errors between its transmission port and the corresponding pipe opening, making the connection process difficult. Generally, it is necessary to adjust the base of the pipeline pump so that the transmission port of the pipeline pump can accurately correspond to the pipe opening. However, the entire adjustment process is cumbersome and the adjustment is not very convenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to improve the ease of adjustment of the pipeline pump base. In view of the shortcomings of the prior art, a pipeline pump base adjustment and fixing device is provided.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a pipeline pump base adjustment and fixing device, including a lifting mechanism and a clamping mechanism. The lifting mechanism is used to be placed on a placement plane and move up and down in the vertical direction. The clamping mechanism includes a locking component and a limiting component. The locking component has at least one set, and the two locking components in each set are symmetrically slidably installed on the lifting mechanism about the vertical direction and are used to move closer to each other to cooperate in clamping the pipeline pump base. The limiting component is installed on the locking component. When the locking component cooperates in clamping the pipeline pump base, the limiting component is used to move at least partially to the top edge of the pipeline pump base.

[0007] Compared to existing technologies, the advantages of this utility model include: The device comprises a lifting mechanism and a clamping mechanism to adjust and fix the pipeline pump base. The lifting mechanism can be placed on a flat surface, serving as a support structure for the entire pipeline pump base adjustment and fixing device, ensuring its stability. Simultaneously, the clamping mechanism comprises engaging components and limiting components. At least one set of engaging components, with two components in each set, are symmetrically slidably mounted on the lifting mechanism about the vertical direction. This allows the pipeline pump base to be clamped by the mutual approach of the two engaging components in each set, achieving stable installation of the pipeline pump base and ensuring the operational stability of the pipeline pump. The lifting mechanism... The structure can also move up and down vertically. With this configuration, after the pipeline pump base is installed via the locking assembly, the entire pipeline pump base can be adjusted by moving the lifting mechanism up and down, improving the convenience of adjusting the pipeline pump base and enabling the pipeline pump to be accurately aligned, ensuring convenient installation of the entire pipeline pump. On this basis, a limiting component can be installed on the locking assembly. When the locking assembly is engaged to clamp the pipeline pump base, the limiting component can move at least partially to the top edge of the pipeline pump base, thereby limiting the upward movement of the pipeline pump base and preventing the pipeline pump base from moving upward and detaching from the locking assembly, thus further ensuring the installation stability of the pipeline pump base.

[0026] An embodiment of this utility model provides a pipeline pump base adjustment and fixing device, including a lifting mechanism 1 and a clamping mechanism 2. The lifting mechanism 1 is used to be placed on the placement plane and move up and down in the vertical direction. The clamping mechanism 2 includes a locking component 21 and a limiting component 22. The locking component 21 has at least one set, and the two locking components 21 in each set are symmetrically slidably mounted on the lifting mechanism 1 about the vertical direction and are used to move closer to each other to cooperate in clamping the pipeline pump base. The limiting component 22 is mounted on the locking component 21. When the locking component 21 cooperates in clamping the pipeline pump base, the limiting component 22 is used to at least partially move to the top edge of the pipeline pump base.

[0027] Specifically, the vertical movement of the lifting mechanism 1 can be achieved by a drive structure such as a telescopic cylinder or a telescopic hydraulic cylinder, or by the operator manually applying driving force.

[0028] In this embodiment, as Figure 1As shown, a lifting mechanism 1 and a clamping mechanism 2 are configured to form a pipeline pump base adjustment and fixing device. The lifting mechanism 1 can be placed on the placement plane, serving as the support structure for the entire pipeline pump base adjustment and fixing device, ensuring the placement stability of the entire pipeline pump base adjustment and fixing device. Simultaneously, a clamping component 21 and a limiting component 22 are configured to form the clamping mechanism 2. At least one set of two clamping components 21 are symmetrically slidably mounted on the lifting mechanism 1 about the vertical direction. This allows the pipeline pump base to be clamped by the mutual approach of the two clamping components 21 in each set, achieving stable installation of the pipeline pump base and ensuring the operational stability of the pipeline pump. The lifting mechanism 1 can also move along the vertical direction... With the pump base installed via the locking assembly 21, the entire pump base can be adjusted by moving the lifting mechanism 1 up and down, improving the ease of adjustment and ensuring accurate alignment of the pump. Furthermore, a limiting assembly 22 can be installed on the locking assembly 21. When the locking assembly 21 clamps the pump base, the limiting assembly 22 can move at least partially to the top edge of the pump base, thus restricting the upward movement of the pump base and preventing it from detaching from the locking assembly 21, further ensuring the stability of the pump base installation.

[0029] Optionally, the lifting mechanism 1 includes a first lifting assembly 11, which includes a first lower stud 111, a first rotating ring 112, and a first upper stud 113. The first upper stud 113, the first rotating ring 112, and the first lower stud 111 are distributed vertically and coaxially corresponding. The inner wall of the first rotating ring 112 engages with the outer wall of the first upper stud 113 and the outer wall of the first lower stud 111, respectively. The clamping mechanism 2 is installed above the first upper stud 113.

[0030] In this optional embodiment, in order to ensure the vertical movement of the lifting mechanism 1, thereby achieving the adjustment of the height of the pipeline pump base, such as... Figure 1 and Figure 2As shown, the lifting mechanism 1 includes a first lifting assembly 11, which consists of a first lower stud 111, a first rotating ring 112, and a first upper stud 113. The first upper stud 113, the first rotating ring 112, and the first lower stud 111 are arranged vertically in a vertically aligned, coaxially corresponding. The inner wall of the first rotating ring 112 meshes with the outer walls of the first upper stud 113 and the first lower stud 111, respectively. This arrangement ensures that when the first rotating ring 112 rotates vertically, the threads mesh, creating a lifting effect. Both the first upper stud 113 and the first lower stud 111 can rotate relative to the first rotating ring 112, thereby reducing or increasing the vertical distance between the first upper stud 113 and the first lower stud 111, thus achieving the extension or shortening of the first lifting assembly 11. On this basis, the clamping mechanism 2 is installed above the first upper stud 113. In this way, the rotation of the first rotating ring 112 can drive the first upper stud 113 to rise and fall, thereby driving the clamping mechanism 2 to rise and fall, thus achieving the adjustment of the pipeline pump base installed on the clamping mechanism 2.

[0031] Optionally, the lifting mechanism 1 further includes a second lifting assembly 12, which is located on one side of the first lifting assembly 11 along the horizontal direction. The second lifting assembly 12 includes a second lower stud 121, a second rotating ring 122, and a second upper stud 123. The second upper stud 123, the second rotating ring 122, and the second lower stud 121 are distributed vertically and coaxially corresponding. The inner wall of the second rotating ring 122 meshes with the outer wall of the second upper stud 123 and the outer wall of the second lower stud 121, respectively. The outer wall of the second rotating ring 122 meshes with the outer wall of the first rotating ring 112.

[0032] In this optional embodiment, in order to ensure the stability of the lifting mechanism 1 during its vertical movement, such as Figure 1 and Figure 2As shown, the lifting mechanism 1 also includes a second lifting assembly 12, which is positioned on one side of the first lifting assembly 11 along the horizontal direction. The second lifting assembly 12 is composed of a second lower stud 121, a second rotating ring 122, and a second upper stud 123. Similar to the first lifting assembly 11, the second upper stud 123, the second rotating ring 122, and the second lower stud 121 are arranged vertically in a vertically aligned manner and coaxially corresponding. The inner wall of the second rotating ring 122 meshes with the outer walls of the second upper stud 123 and the second lower stud 121, respectively, for transmission. Thus, the rotation of the second rotating ring 122... The second lifting component 12 is extended and shortened. Based on this, the outer wall of the second rotating ring 122 meshes with the outer wall of the first rotating ring 112 for transmission. With this configuration, the first rotating ring 112 and the second rotating ring 122 can rotate synchronously. When the first rotating ring 112 rotates, not only can the first lifting component 11 be extended and shortened, but the second rotating ring 122 can also be driven to rotate through the first rotating ring 112, thereby extending and shortening the second lifting component 12. The lifting and shortening of the clamping mechanism 2 is achieved through the cooperation of the first lifting component 11 and the second lifting component 12, ensuring the stability of the lifting mechanism 1 during the up and down movement process.

[0033] Optionally, the lifting mechanism 1 further includes a transmission assembly 13. There are multiple second lifting assemblies 12. The first lifting assembly 11 and multiple second lifting assemblies 12 are distributed at equal intervals around the transmission assembly 13. The transmission assembly 13 includes a third lower stud 131 and a third rotating ring 132. The third rotating ring 132 and the third lower stud 131 are distributed vertically in sequence and coaxially corresponding. The inner wall of the third rotating ring 132 meshes with the outer wall of the third lower stud 131 for transmission. The outer wall of the first rotating ring 112 meshes with the outer walls of multiple second rotating rings 122 through the outer wall of the third rotating ring 132 for transmission.

[0034] In this optional embodiment, in order to further ensure the stability of the lifting mechanism 1 during its vertical movement, such as... Figure 1 and Figure 2As shown, multiple second lifting components 12 are configured. To ensure the stability of the first rotating ring 112 and the second rotating ring 122 during synchronous transmission, the lifting mechanism 1 is also provided with a transmission component 13. The first lifting component 11 and multiple second lifting components 12 are distributed at equal intervals around the transmission component 13. The transmission component 13 is composed of a third lower stud 131 and a third rotating ring 132. The third rotating ring 132 and the third lower stud 131 are distributed vertically and coaxially corresponding. The inner wall of the third rotating ring 132 meshes with the outer wall of the third lower stud 131 for transmission. The outer wall of the first rotating ring 112 meshes with the outer walls of multiple second rotating rings 122 through the outer wall of the third rotating ring 132. With this configuration, when the first rotating ring 112 rotates, the rotational force can be synchronously transmitted to multiple second rotating rings 122 through the third rotating ring 132, thereby realizing the synchronous extension and shortening of the first lifting component 11 and multiple second lifting components 12. In turn, the lifting and lowering adjustment of the clamping mechanism 2 is driven by the cooperation of the first lifting component 11 and multiple second lifting components 12.

[0035] Optionally, the lifting mechanism 1 further includes a base plate 14 and a top plate 15, which are spaced vertically apart. The first lifting assembly 11 is installed between the top plate 15 and the base plate 14, and the clamping mechanism 2 is installed on the top wall of the top plate 15. And / or, a force-receiving ring 114 is coaxially connected to the first rotating ring 112. The force-receiving ring 114 is used to rotate around the vertical direction under force to drive the first rotating ring 112 to rotate.

[0036] In this optional embodiment, in order to ensure the stability of the lifting mechanism 1 when driving the clamping mechanism 2 to lift and adjust, the lifting mechanism 1 is also provided with a bottom plate 14 and a top plate 15, wherein the top plate 15 and the bottom plate 14 are distributed vertically at intervals, and the first lifting component 11 can be installed between the top plate 15 and the bottom plate 14, thereby forming an I-shaped structure to ensure the structural stability of the entire lifting mechanism 1; on this basis, the clamping mechanism 2 is installed on the top wall of the top plate 15. When the bottom plate 14 is placed on the placement plane, the extension and retraction of the first lifting component 11 can drive the top plate 15 to move up and down, thereby driving the clamping mechanism 2 to lift and lower.

[0037] This optional embodiment or other optional embodiments of the present invention, such as Figure 2 As shown, a force-bearing ring 114 is coaxially connected to the first rotating ring 112. The force-bearing ring 114 can be rotated in the vertical direction under force, thereby driving the first rotating ring 112 to rotate, realizing the extension and retraction of the first lifting assembly 11, and ensuring the convenience of the lifting mechanism 1 to adjust the pipeline pump base through the clamping mechanism 2.

[0038] Optionally, the engaging assembly 21 includes an engaging block 211 and an elastic block 212. The elastic block 212 is used to extend and retract in the horizontal direction, and one end is mounted on the lifting mechanism 1. The engaging block 211 is horizontally separated from the engaging block 211 of another engaging assembly 21 in the same group, and the other end of the elastic block 212 is connected.

[0039] Specifically, the elastic block 212 is a rubber block, such as... Figure 1 As shown, the upper part of the end face of the locking block 211 facing the other locking block 211 symmetrically is an inclined surface.

[0040] In this optional embodiment, such as Figure 1 and Figure 2 As shown, a locking assembly 21 is formed by locking block 211 and elastic block 212. The elastic block 212 can extend and retract in the horizontal direction, and one end is mounted on the lifting mechanism 1. The locking block 211 is horizontally separated from the other locking assembly 21 in the same group. One end of the locking block 211 is connected to the other end of the elastic block 212. With this configuration, when the pipeline pump base is placed on the clamping mechanism 2, the locking block 211 can be squeezed to move in the horizontal direction and squeeze the elastic block 212. After the pipeline pump base is installed in place, under the drive of the elastic force of the elastic block 212, the locking block 211 can cooperate to clamp the pipeline pump base, ensuring the installation stability of the pipeline pump base.

[0041] Optionally, the upper end face of the lifting mechanism 1 is provided with a sliding groove 16, and the engaging assembly 21 further includes a sliding block 213 and a transition block 214. The sliding block 213 is installed in the sliding groove 16 and is used to move closer to or away from the central axis of the lifting mechanism 1 along the sliding groove 16. The elastic block 212 is connected to the inner side wall of the sliding groove 16 and the sliding block 213 respectively, and is located on the side of the sliding block 213 away from the central axis of the lifting mechanism 1. The opening size of the sliding groove 16 is smaller than the internal size of the sliding groove 16. The transition block 214 passes through the opening of the sliding groove 16 and is connected to the sliding block 213 and the engaging block 211 respectively.

[0042] In this optional embodiment, in order to ensure the stability of the engaging component 21 during clamping, such as Figure 1 and Figure 2As shown, the upper surface of the lifting mechanism 1 is provided with a sliding groove 16, and the engaging assembly 21 is also provided with a sliding block 213 placed in the sliding groove 16. The sliding block 213 can move closer to or away from the central axis of the lifting mechanism 1 along the sliding groove 16. The elastic block 212 is connected to the inner side wall of the sliding groove 16 and the sliding block 213 respectively, and is located on the side of the sliding block 213 away from the central axis of the lifting mechanism 1. At the same time, the engaging assembly 21 is also provided with a transition block 214 connected to the engaging block 211 and the sliding block 213 respectively. In this way, the sliding groove 16 can limit the sliding block 213, ensuring the movement stability of the engaging block 211, and thus ensuring the stability of the engaging assembly 21 when it is engaged and clamped. On this basis, the opening size of the sliding groove 16 is smaller than the internal size of the sliding groove 16, and the transition block 214 passes through the opening of the sliding groove 16, thereby preventing the sliding block 213 from moving out of the inside of the sliding groove 16, ensuring the stability of the engaging block 211 during the movement.

[0043] Optionally, within a set of engaging components 21, the end face of one engaging block 211 facing another engaging block 211 is an arc surface, and the arc surfaces of the engaging blocks 211 of multiple sets of engaging components 21 are all located on the same annular surface.

[0044] In this optional embodiment, since the sidewall of the pipeline pump base is arc-shaped, therefore, as Figure 1 As shown, in a set of locking components 21, the end face of one locking block 211 facing another locking block 211 is an arc surface. The arc surfaces of the locking blocks 211 in multiple sets of locking components 21 are all located on the same annular surface. This arrangement allows the locking blocks 211 to fit against the side wall of the pipeline pump base, effectively ensuring the stability of the locking blocks 211 in clamping the pipeline pump base.

[0045] Optionally, the clamping mechanism 2 also includes a buffer pad 23, which is located at the center of the upper end face of the lifting mechanism 1.

[0046] In this optional embodiment, since the pipeline pump is prone to vibration during operation, in order to reduce the adverse effects of vibration on the pipeline pump base adjustment and fixing device, such as... Figure 1 and Figure 2 As shown, the clamping mechanism 2 is also provided with a buffer pad 23. The buffer pad 23 can be a rubber pad or a spring pad. The buffer pad 23 is placed at the center of the upper end face of the lifting mechanism 1. After the pipeline pump base is installed in place, the buffer pad 23 can abut against and compress the bottom wall of the pipeline pump base. When the pipeline pump vibrates, the buffer pad 23 can absorb the vibration force through expansion and contraction, ensuring the structural stability of the pipeline pump base adjustment and fixing device.

[0047] Optionally, the limiting component 22 includes a limiting block 221, a threaded rod 222, and a handle 223. The end face of the engaging block 211 facing the central axis of the lifting mechanism 1 has an opening, and the limiting block 221 is located in the opening. The end face of the engaging block 211 away from the central axis of the lifting mechanism 1 has a threaded hole communicating with the opening. One end of the threaded rod 222 passes through the threaded hole and abuts against the limiting block 221, and the other end is connected to the handle 223. The handle 223 is used to rotate under force to drive the threaded rod 222 to rotate.

[0048] In this optional embodiment, such as Figure 1 and Figure 2 As shown, a limiting assembly 22 is formed by a limiting block 221, a threaded rod 222, and a handle 223. The end face of the engaging block 211 facing the central axis of the lifting mechanism 1 has an opening, and the limiting block 221 is located in the opening. The end face of the engaging block 211 away from the central axis of the lifting mechanism 1 has a threaded hole communicating with the opening. One end of the threaded rod 222 passes through the threaded hole and abuts against the limiting block 221, while the other end is connected to the handle 223. The handle 223 can be rotated under force to drive the threaded rod 222 to rotate. With this configuration, rotating the handle 223 can drive the threaded rod 222 to rotate, thereby causing the threaded rod 222 to push the limiting block 221 to partially extend out of the engaging block 211 and abut against the edge and top wall of the pipeline pump base, thus limiting the pipeline pump base. At the same time, the engagement of the threaded rod 222 with the threaded hole can ensure the stability of the position of the limiting block 221.

[0049] It should be noted that a blind hole can be provided on the side wall of the limiting block 221, and the end of the threaded rod 222 is placed in the blind hole and can rotate within the blind hole.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
