[0026] The pipeline pump is a single-suction single-stage or multi-stage centrifugal pump. In the related art, the pipeline pump is vertically arranged, and the inlet and outlet thereof are located on the two sides in the horizontal direction. When the pipeline pump is fixed, the pipeline pump is usually carried and fixed above the support structure. Since the pipeline pump is only fixed at the bottom, the pipeline pump may still shake under the action of external force, which causes wear of the pipeline pump. Moreover, when the installation height is high, the installation of the pipeline pump is also inconvenient.

[0027] Based on the above problems, the present application provides a pipeline pump fixing frame 100 for installing and fixing the pipeline pump, which can improve the stability and convenience of the installation of the pipeline pump. Of course, the pipeline pump support 1 can also be used for the installation of other types of pump bodies.

[0028] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the pipeline pump fixing frame 100 comprises a support 1, a clamping structure 2 and a lifting structure 3. The clamping structure 2 comprises a first motor 31, a locking piece 23 and oppositely arranged first and second clamping pieces 21 and 22. The first clamping piece 21 is arranged on the support 1 in a lifting manner. The first and second clamping pieces 21 and 22 enclose to form an installation hole 26. The second clamping piece 22 can be opened and closed relative to the first clamping piece 21. One end of the first clamping piece 21 is provided with a first fixing part 211, and one end of the second clamping piece 22 is provided with a second fixing part 221. One of the first fixing part 211 and the second fixing part 221 is provided with a screw hole, and the other of the first fixing part 211 and the second fixing part 221 is provided with the first motor 31. The locking piece 23 is provided with an external thread. The locking piece 23 is arranged through the first fixing part 211 and the second fixing part 221 and threadedly matched with the screw hole. The first motor 31 is connected with the locking piece 23, and is used for driving the locking piece 23 to rotate. The lifting structure 3 is arranged on the support 1 and connected with the first clamping piece 21, and is used for driving the clamping structure 2 to lift.

[0029] In the embodiment of the present application, the pipeline pump fixing frame 100 comprises a support 1 as a bearing base and a clamping structure 2 arranged on the support 1; the clamping structure 2 comprises oppositely arranged first and second clamping members 21 and 22, which are arranged along the horizontal direction or approximately along the horizontal direction, and the first and second clamping members 21 and 22 can each be arranged as a half-ring structure, so as to enclose an installation hole 26; or one of the first and second clamping members 21 and 22 is arranged as an open-loop structure, and the other is arranged as a plate or other shape, for closing the open-loop structure to form the installation hole 26. Among them, the contour of the installation hole 26 can be a round hole, a square hole, a rectangular hole, and other regular or irregular shapes, which can be set according to the cross-sectional contour of the pipeline pump body to be installed and fixed, and the contour of the installation hole 26 can be completely consistent with the cross-sectional contour of the pipeline pump body, or the installation hole 26 can be partially adapted to the cross-sectional contour of the pipeline pump body, for example, when the cross-section of the pipeline pump body is circular, the installation hole 26 can be a round hole, or the installation hole 26 can be a semicircular hole or other shapes with arc contour.

[0030] In the embodiment, the first clamping member 21 has two ends arranged along the circumference of the installation hole 26, and the second clamping member 22 also has two ends arranged along the circumference of the installation hole 26; wherein the two ends of the first clamping member 21 can be detachably connected with the two ends of the second clamping member 22, or the first and second clamping members 21 and 22 can be rotationally connected at one end on the same side and detachably connected at the other end; both can realize the opening and closing of the clamping structure 2 to loosen or clamp the clamping structure 2.

[0031] When installing the pipeline pump, the pump body of the pipeline pump is installed in the installation hole 26 of the clamping structure 2, and the first and second clamping members 21 and 22 are moved close to each other to clamp the pump body; so that at least part of the circumferential area of the pipeline pump body is constrained and positioned by the clamping structure 2; compared with the method of fixing only the bottom of the pump, the installation stability of the installed pump is improved. In some embodiments, the clamping structure 2 formed by the first and second clamping members 21 and 22 is approximately a cylindrical structure with through holes at both ends, and the installation hole 26 formed by the clamping structure 2 has a certain length in the axial direction, which can increase the contact area with the pipeline pump, improve the clamping strength of the pipeline pump, and reduce the risk of shaking and instability of the pipeline pump after being fixed.

[0032] And, in the embodiment of the present application, the support 1 is also provided with a lifting structure 3, which can drive the clamping structure 2 to lift. Among them, the lifting structure 3 can adopt a motor as a driving part, and is connected with the clamping structure 2 through a transmission mechanism such as a screw rod transmission, a gear and rack transmission, a worm and gear transmission, so as to drive the clamping structure 2 to lift; the lifting structure 3 can also adopt a driving structure such as a pneumatic cylinder or a hydraulic cylinder to control the lifting, for example, the clamping structure 2 can be connected with the piston rod of the pneumatic cylinder or the hydraulic cylinder, so as to realize the lifting when the piston rod extends or retracts; the lifting structure 3 can also adopt a scissor type lifting mechanism, etc., which is not limited here.

[0033] In this way, when it is necessary to install the pipeline pump at a higher position, the pipeline pump can be first fixed to the clamping structure 2 at a low position, and then the clamping structure 2 and the pipeline pump are lifted to the required height position by the lifting structure 3, thereby improving the installation convenience of the pump installation; the installation height of the pipeline pump can also be adjusted, which is suitable for different use requirements.

[0034] In the embodiment of the present application, the first clamping part 21 has two ends spaced circumferentially along the mounting hole 26, and a first fixing part 211 is arranged at one end of the first clamping part 21; the second clamping part 22 also has two ends spaced circumferentially along the mounting hole 26, and a second fixing part 221 is arranged at the same side of the second clamping part 22 as the first fixing part 211, so that the first fixing part 211 and the second fixing part 221 can be detachably connected; the connection mode between the first fixing part 211 and the second fixing part 221 can include at least one of buckle connection, bolt connection and binding connection. In this way, the clamping structure 2 can be loosened by detaching the first fixing part 211 and the second fixing part 221, so that the pipeline pump can be taken out or put into the mounting hole 26.

[0035] In the embodiment, the other end of the first clamping part 21 and the second clamping part 22 away from the first fixing part 211 and the second fixing part 221 can also be provided as a detachable connection structure. In this way, the second clamping part 22 can be detached from the first clamping part 21 as a whole, and different shapes of the second clamping part 22 can be replaced to fix pipeline pumps of different shapes; in some embodiments, the end of the first clamping part 21 away from the first fixing part 211 can be rotatably connected with the end of the second clamping part 22 away from the second fixing part 221, so that the second clamping part 22 and the first clamping part 21 are always connected, reducing the risk of losing the second clamping part 22. By rotating the second clamping part 22, the clamping structure 2 can be opened and closed, and only the end provided with the first fixing part 211 and the second fixing part 221 needs to be disassembled, thereby improving the application convenience of the clamping structure 2.

[0036] Specifically, a screw hole can be arranged on the first fixing part 211, and a through hole can be arranged on the second fixing part 221 correspondingly; or a screw hole can be arranged on the second fixing part 221, and a through hole can be arranged on the first fixing part 211 correspondingly. When the first clamping part 21 and the second clamping part 22 are closed to make the clamping structure 2 shrink, the screw hole and the through hole are arranged oppositely, and the locking part 23 can be a structure provided with external threads such as a screw or a bolt.

[0037] Taking the example that the first fixing part 211 is provided with a screw hole and the second fixing part 221 is provided with a through hole, the locking part 23 can be arranged in the through hole and then inserted into the screw hole to threadedly cooperate with the screw hole. In this way, the locking part 23 can be fixed to the second fixing part 221 at one end of the through hole. For example, a bolt is used as the locking part 23, the head of the bolt can abut against the surface of the second fixing part 221 away from the first fixing part 211, and when the bolt threadedly cooperates with the screw hole of the first fixing part 211, rotating the bolt can drive the second fixing part 221 to move close to or away from the first fixing part 211, so as to realize the shrinkage or relaxation of the clamping structure 2. Of course, as in the following embodiment, a first motor 31 can be arranged on the side of the second fixing part 221 away from the first fixing part 211, the first motor 31 is connected with the locking part 23 and can drive the locking part 23 to rotate, and the locking part 23 and the second fixing part 221 are connected with each other. When the first motor 31 drives the locking part 23 to rotate, the first fixing part 211 will slide along the length direction of the locking part 23 to move close to or away from the first fixing part 211, so as to realize the shrinkage or relaxation of the clamping structure 2.

[0038] In this way, the locking part 23 cooperates with the screw hole to lock the first fixing part 211 and the second fixing part 221, which can provide high connection strength and can withstand large tensile force and shear force, thereby improving the strength of the clamping structure 2 for locking the pipeline pump.

[0039] In the embodiment, the screw hole arranged on the first fixing part 211 or the second fixing part 221 can be directly arranged on the first fixing part 211 or the second fixing part 221, which can reduce the number of parts in the clamping structure 2. Of course, a nut 25 can be fixed on the first fixing part 211 or the second fixing part 221 to form a screw hole. In this way, the depth of the screw hole is not limited by the thickness of the first fixing part 211 and the second fixing part 221, which is beneficial to improve the connection strength.

[0040] Please refer to Figure 3In an embodiment, a screw hole can be arranged on the first fixing part 211, a through hole can be arranged on the second fixing part 221, and the first motor 31 can be fixed on the second fixing part 221, the first motor 31 being arranged on the side of the second fixing part 221 away from the first fixing part 211 and connected with the locking member 23. Alternatively, a screw hole can be arranged on the second fixing part 221, a through hole can be arranged on the first fixing part 211, and the first motor 31 can be fixed on the first fixing part 211, the first motor 31 being arranged on the side of the first fixing part 211 away from the second fixing part 221 and connected with the locking member 23. In this way, when the locking member 23 is inserted into the screw hole and the first motor 31 drives the locking member 23 to rotate, the first fixing part 211 and the second fixing part 221 can approach or move away from each other, so as to realize the contraction or relaxation of the clamping structure 2. The first motor 31 drives the locking member 23 to rotate in different directions, i.e., the contraction and relaxation of the clamping structure 2 can be realized respectively.

[0041] In this way, the length of the locking member 23 inserted into the screw hole can be adjusted by driving the locking member 23 to rotate by the first motor 31, so that the clamping structure 2 is automatically locked or relaxed, and the use convenience is improved.

[0042] Please refer to Figure 3 In an embodiment, the end of the first clamping member 21 away from the first fixing part 211 is rotatably connected with the end of the second clamping member 22 away from the second fixing part 221. In this way, when the first fixing part 211 and the second fixing part 221 are loosened, the first clamping member 21 and the second clamping member 22 remain connected, the clamping structure 2 can be opened and closed by rotating the second clamping member 22, and only one end provided with the first fixing part 211 and the second fixing part 221 needs to be disassembled, so that the use is more convenient.

[0043] In this way, the end of the first clamping member 21 away from the first fixing part 211 is rotatably connected with the end of the second clamping member 22 away from the second fixing part 221. In this way, when the first fixing part 211 and the second fixing part 221 are loosened, the first clamping member 21 and the second clamping member 22 remain connected, the clamping structure 2 can be opened and closed by rotating the second clamping member 22, and only one end provided with the first fixing part 211 and the second fixing part 221 needs to be disassembled, so that the use is more convenient.

[0044] Please refer to Figure 1 and Figure 2In an embodiment, the lifting structure 3 comprises a second motor 24 and a screw drive mechanism 32, the second motor 24 is in screw drive connection with the screw drive mechanism 32, and the screw nut of the screw drive mechanism 32 is connected with the first clamping member 21. In this embodiment, the second motor 24 is used as the driving member, and the screw drive mechanism 32 is used to connect the second motor 24 and the first clamping member 21 of the clamping structure 2, the screw of the screw drive mechanism 32 is connected with the second motor 24, so as to rotate under the driving of the second motor 24, thereby driving the screw nut to slide along the screw and lift the clamping structure 2.

[0045] In this way, the lifting of the clamping structure 2 is controlled by the motor and the screw drive mechanism 32, which has high positioning and repeat positioning accuracy, strong load capacity, and can improve the positioning accuracy of the installation height of the pipeline pump and the safety during lifting.

[0046] Please refer to Figure 1 In an embodiment, the pipeline pump fixing frame 100 further comprises a connecting structure 4, one end of the connecting structure 4 is connected with the lifting structure 3, and the other end of the connecting structure 4 is connected with the first clamping member 21.

[0047] The connecting structure 4 can be rod-shaped, block-shaped, or other regular or irregular structures, and the connection between the connecting structure 4 and the first clamping member 21 can be detachable or non-detachable, such as welding, fusion, or one-piece forming. The end of the connecting structure 4 away from the first clamping member 21 can be detachably connected with the movable part of the lifting structure 3, such as the screw nut of the screw drive mechanism 32 or the piston rod of the pneumatic cylinder or hydraulic cylinder. Of course, the connection between the connecting structure 4 and the lifting structure 3 varies according to different types of lifting structure 3. By connecting the first clamping member 21 and the lifting structure 3 through the connecting structure 4, the mutual interference between the clamping structure 2 and the lifting structure 3 can be avoided, and the structure and position of the clamping structure 2 and the lifting structure 3 can be more flexible, such as at least part of the lifting structure 3 being accommodated in the accommodating space of the support 1 in the following embodiments.

[0048] Please refer to Figure 1 In an embodiment, the connecting structure 4 is arranged on the side of the first clamping member 21 away from the second clamping member 22. In this way, the second clamping member 22 is located on the side of the first clamping member 21 away from the support 1 and the lifting structure 3, which can reduce the interference of the support 1 and the lifting structure with the movement of the second clamping member 22 when the second clamping member 22 is opened or closed.

[0049] Please refer to Figure 1 and Figure 2In an embodiment, the bracket 1 is provided with a receiving space, and at least part of the lifting structure 3 is arranged in the receiving space. The side wall of the bracket 1 is provided with an avoiding hole extending along the height direction of the receiving space, and the connecting structure 4 is arranged in the avoiding hole to connect the clamping structure 2 and the lifting structure 3.

The bracket 1 is provided with a receiving space, and the side wall of the receiving space is provided with an avoiding hole communicating with the outside, and the avoiding hole is a long hole extending along the height direction of the receiving space. The entire lifting structure 3 can be arranged in the receiving space, or part of the lifting structure 3 can be arranged in the receiving space, for example, the screw drive mechanism 32 can be arranged in the receiving space, and the first motor 31 can be arranged outside the receiving space in the illustrated embodiment. The connecting structure 4 is arranged in the avoiding hole of the side wall of the bracket 1 and connected with the clamping structure 2 outside the receiving space. In this arrangement, the bracket 1 can protect the lifting structure 3 and reduce the risk of damage to the lifting structure 3.

The first motor 31 is arranged on the top of the bracket 1 through the support structure 12, the screw drive mechanism 32 is arranged in the receiving space, and the top of the receiving space is opened to enable the screw to be connected with the first motor 31. In this way, the first motor 31 can be connected with a power supply structure, and the bracket 1 does not need to be arranged too high. Of course, when other transmission mechanisms are used in cooperation with the first motor 31 to form the lifting structure 3, the transmission mechanism can be arranged in the receiving space, and the first motor 31 can be exposed outside the receiving space.

[0052] Referring to Figure 1 and Figure 2 In an embodiment, the pipeline pump fixing bracket 100 further includes a cable bridge fixing seat 5 arranged in the bracket 1. In this arrangement, the pipeline pump fixing bracket 100 can be used to fix the cable of the pipeline pump, avoid the cable from shaking and affecting the installation stability of the pipeline pump, and improve the connection stability of the cable and the pipeline pump.

[0053] Referring to Figure 1 and Figure 2 In some embodiments, the side wall of the bracket 1 is provided with a support portion 13, and the cable bridge fixing seat 5 is arranged at the end of the support portion 13 away from the bracket 1. In this way, the cable can be arranged away from the bracket 1 when the cable is fixed, and the cable can be prevented from being abraded on the surface of the bracket 1.

[0054] Referring to Figure 1 and Figure 2In an embodiment, the cable bridge fixing seat 5 comprises two clamping portions 51 arranged oppositely and capable of moving towards or away from each other.

[0055] In the embodiment, the cable can be clamped between the two clamping portions 51 of the cable bridge fixing seat 5, wherein the two clamping portions 51 can directly clamp the cable or can enclose a cable routing channel for clamping the cable. The two clamping portions 51 can move away from or towards each other, can be connected by the connecting member 52 in the following embodiment, or can be detachably connected by buckle connection or the like on the same side of the side edges. The cable is fixed by clamping, which is simple in structure and convenient to operate.

[0056] Please refer to Figure 1 and Figure 2 In an embodiment, the surface of at least one clamping portion 51 facing the other clamping portion 51 is concave and provided with a limiting groove 511 penetrating through both ends. In the embodiment, the limiting groove 511 can be provided on the clamping surface of one clamping portion 51 of the cable bridge fixing seat 5, or can be provided on the clamping surfaces of the two clamping portions 51. The limiting groove 511 penetrates through both ends, and when the cable is clamped between the two clamping portions 51, the cable can extend outward from both ends. The limiting groove 511 can limit the cable by the groove walls on both sides of the limiting groove 511, so as to prevent the cable from falling out of the side of the two clamping portions 51 and improve the stability of the fixed cable.

[0057] Please refer to Figure 1 and Figure 2 In an embodiment, the cable bridge fixing seat 5 further comprises a connecting member 52 penetrating through the two clamping portions 51 to connect the two clamping portions 51.

[0058] Such a structure can move the two clamping portions 51 towards or away from each other along the connecting member 52 to adjust the size and tightness of the clamping space between the two clamping portions 51, which is convenient to operate. When the connecting member 52 is threadedly connected with the clamping portion 51, the connecting strength can be higher.

[0059] Please refer to Figure 1 and Figure 2 In an embodiment, the outer side wall of the bracket 1 is provided with an instrument fixing position 11. In this way, the instrument for displaying the pipeline pump information can be fixed on the bracket 1, which is convenient for observation and use.

[0060] Please refer to Figure 1 and Figure 2 Figure 1 Figure 2In an embodiment, the outer side wall of the bracket 1 is concavely provided with a groove to form an instrument fixing position 11. In this way, when the instrument is installed on the bracket 1, it can be fixed in the groove to limit the position of the instrument, thereby improving the stability of the installation position of the instrument. In some embodiments, the depth of the groove can be not less than the thickness of the instrument, so that the instrument does not protrude from the outer side wall of the bracket 1, and the risk of the instrument being impacted by external objects can be reduced.

[0061] The present application also provides a pipeline pump assembly, which comprises a pipeline pump and a pipeline pump fixing frame 100 according to any one of the preceding embodiments. The pipeline pump is a single-suction single-stage or multi-stage centrifugal pump. The pipeline pump fixing frame 100 comprises a bracket 1, a clamping structure 2 and a lifting structure 3. The clamping structure 2 comprises a first clamping piece 21 and a second clamping piece 22 which are oppositely arranged in the horizontal direction. The first clamping piece 21 is arranged on the bracket 1 in a liftable manner. The first clamping piece 21 and the second clamping piece 22 enclose an installation hole 26. The second clamping piece 22 can be opened and closed relative to the first clamping piece 21. The lifting structure 3 is arranged on the bracket 1 and connected with the first clamping piece 21, and is used to drive the clamping structure 2 to lift. The pipeline pump is installed in the installation hole 26 and fixed by the first clamping piece 21 and the second clamping piece 22.

[0062] The technical scheme of the present application provides the clamping structure 2 in the pipeline pump fixing frame 100. When the pipeline pump is installed, the pump body of the pipeline pump is installed in the installation hole 26 of the clamping part 51 and clamped by the first clamping piece 21 and the second clamping piece 22. At least part of the circumferential region of the pump body of the pipeline pump is constrained and limited by the clamping structure 2. Compared with the method of fixing only the bottom of the pump, the installation stability of the pump is improved. In the embodiment of the present application, the clamping structure 2 can be driven to lift by the lifting structure 3. When it is needed to install the pipeline pump at a higher position, the pipeline pump can be first fixed on the clamping structure 2 at a lower position, and then the clamping structure 2 and the pipeline pump are lifted to the required height position by the lifting structure 3, thereby improving the installation convenience of the pump.

[0063] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the technical concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
