Description

Technical Field

[0001] The utility model relates to the technical field of double-suction pumps, in particular to a shock-absorbing double-suction pump. Background Art

[0002] Under the background of traditional double-suction pumps, only the shock-absorbing requirements in the working state are usually considered, while the problem of absorbing the bumps and vibrations in the device transfer state is ignored. Traditional double-suction pumps are usually only equipped with working shock-absorbing structures, such as simple shock-absorbing pads and spring dampers, to absorb and weaken the vibrations generated by the double-suction pump in the working state.

[0003] However, in practical applications, the double-suction pump not only needs to operate stably in the working state, but also needs to remain stable during device transfer, especially when it may face challenges of bumps and vibrations during the transfer process. Since traditional double-suction pumps lack a special shock-absorbing structure for bumps and vibrations in the transfer state, during the transfer process, the pump body is easily subjected to large impacts and damages, thus affecting the reliability and service life of the equipment.

[0004] Therefore, this solution particularly proposes a shock-absorbing double-suction pump to solve the above problems. Content of the Utility Model

[0005] To overcome the defects of the prior art, the purpose of the utility model is to provide a shock-absorbing double-suction pump.

[0006] To achieve the above object, the technical solution of the utility model is realized as follows: A shock-absorbing double-suction pump includes a double-suction pump body and a shock-absorbing machine box. The top of the shock-absorbing machine box is not closed and is slidably and detachably connected with a double-suction pump installation platform. First installation grooves are arranged on the box walls near the four corner ends inside the shock-absorbing machine box, and transfer shock-absorbing components are installed inside each of the first installation grooves. An installation plate is further arranged inside the shock-absorbing machine box below the double-suction pump installation platform, a working shock-absorbing component is installed on the top of the installation plate, and a jacking mechanism for lifting and supporting the working shock-absorbing component on the bottom surface of the double-suction pump installation platform is installed on the inner bottom of the shock-absorbing machine box.

[0007] Preferably, the jacking mechanism specifically includes the following structures:

[0008] Two installation sliding platforms symmetrically and parallelly distributed on the inner bottom of the shock-absorbing machine box;

[0009] A number of herringbone articulated frames supported between the tops of the two sides of the installation sliding platforms and the bottom of the installation plate;

[0010] An angle adjustment mechanism distributed inside the bottom surface of the shock-absorbing machine box to drive the corresponding sides of the two installation sliding platforms to adjust the included angle at the top of the herringbone articulated frame.

[0011] Preferably, the angle adjustment mechanism specifically includes the following structure:

[0012] A lead screw sleeve correspondingly connected to the center positions of the bottoms of the two installation sliding tables;

[0013] A driving lead screw correspondingly threaded through the interiors of the two lead screw sleeves;

[0014] A double-shaft reduction motor located at the center positions of the two driving lead screws and respectively butted against the inner ends of the two driving lead screws.

[0015] Preferably, the working shock-absorbing assembly specifically includes the following structure:

[0016] Shock-absorbing pads distributed on the top surface of the mounting plate;

[0017] Spring dampers correspondingly installed at the four corner ends of the top surface of the mounting plate.

[0018] Preferably, the transfer shock-absorbing assembly specifically includes the following structure:

[0019] Slide columns distributed inside the first installation groove at the same position;

[0020] A connecting sleeve slidably sleeved on the slide column, with the inner pipe wall of the connecting sleeve fixedly connected to the same side of the double-suction pump mounting table;

[0021] A buffer spring sleeved on the slide column and with its top end supporting the lower end surface of the connecting sleeve.

[0022] Preferably, second installation grooves are provided at the centers of the front and rear side walls inside the shock-absorbing machine case, and guiding assemblies connected to the double-suction pump mounting table are installed inside the second installation grooves.

[0023] Preferably, the guiding assembly specifically includes the following structure:

[0024] A guiding column installed inside the second installation groove;

[0025] A guiding sleeve slidably sleeved on the guiding column, with the inner pipe wall of the guiding sleeve fixedly connected to the center of the same side of the double-suction pump mounting table.

[0026] Preferably, the shock-absorbing double-suction pump specifically includes two modes: working shock absorption and moving shock absorption.

[0027] Preferably, telescopic support columns are installed at the four corner ends of the inner bottom of the shock-absorbing machine case, and the top ends of the four telescopic support columns respectively support the four corner ends of the bottom of the mounting plate

[0028] The beneficial effects of the present utility model are embodied in:

[0029] Through the design of the shock-absorbing chassis, the double-suction pump installation platform can slide freely up and down therein to adapt to different shock-absorbing modes. The combination of the working shock-absorbing component and the transfer shock-absorbing component effectively absorbs and weakens the vibrations generated by the double-suction pump during the working and transfer states, thereby extending the service life of the pump body and improving the overall working efficiency.

[0030] In the working shock-absorbing mode, the working shock-absorbing component further absorbs and weakens the vibrations through the structure of the shock-absorbing backing plate and the spring damper, protecting the stability and reliability of the double-suction pump under high-frequency vibration conditions.

[0031] In the transfer shock-absorbing mode, the combination of the sliding column, connecting sleeve and buffer spring of the transfer shock-absorbing component effectively buffers and absorbs the bumpy vibrations during the transfer process, reducing the damage risk of the double-suction pump during the transfer process and enhancing the durability of the device.

[0032] The precise adjustment of the lifting mechanism makes the conversion from the transfer shock-absorbing mode to the working shock-absorbing mode more flexible, ensuring the continuity and stability of the shock-absorbing effect. At the same time, the design of the guiding component ensures the stable movement of the double-suction pump installation platform in the shock-absorbing chassis, further improving the reliability and accuracy of the overall system.

[0033] In summary, this shock-absorbing double-suction pump not only fully considers the vibration absorption and weakening of the double-suction pump during the working and transfer states in its design, but also realizes the flexible switching between modes and stable operation through the precise design of the lifting mechanism and the guiding component, thereby ensuring the efficient, stable and reliable operation of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0052] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0053] In addition, "a plurality of" means two or more. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.

[0054] Please refer to the attached drawings of the specification Figures 1-8, the present utility model provides a shock-absorbing double-suction pump, which includes a double-suction pump body 1 and a shock-absorbing chassis 2. The top of the shock-absorbing chassis 2 is not closed, and a double-suction pump mounting table 7 can be slidably clamped up and down. This design enables the double-suction pump mounting table 7 to freely slide up and down within the shock-absorbing chassis 2 to adapt to the two shock-absorbing modes of the bottom working shock-absorbing component 6 and the transfer shock-absorbing component 8.

[0055] First mounting grooves 21 are provided on the inner box walls near the four corner ends of the shock-absorbing chassis 2. A transfer shock-absorbing component 8 is installed inside each first mounting groove 21. The function of the transfer shock-absorbing component 8 is to absorb the bumpy vibration energy during the transfer process when the double-suction pump is in a non-working and transfer state, thereby reducing damage to the pump body. The shock-absorbing buffer stroke of the transfer shock-absorbing component 8 is larger and has better elasticity, and it is more suitable for shock-absorbing protection during transfer compared to the working shock-absorbing component 6.

[0056] An installation plate 5 is further provided inside the shock-absorbing chassis 2 below the double-suction pump mounting table 7. A working shock-absorbing component 6 is installed on the top of the installation plate 5 to further absorb and weaken vibrations when the double-suction pump is working.

[0057] A jacking mechanism 3 is installed at the bottom inside the shock-absorbing chassis 2 to lift and support the working shock-absorbing component 6 on the bottom surface of the double-suction pump mounting table 7. At this time, the buffer space of the transfer shock-absorbing component 8 is locked by the working shock-absorbing component 6, and only the working shock-absorbing component 6 exerts the shock-absorbing effect at this time. The vibration stroke of the working shock-absorbing component 6 is short, and at the same time, its elasticity is slightly poor, but it is more suitable for high-frequency vibration protection when the double-suction pump body 1 is working.

[0058] The jacking mechanism 3 includes the following structure:

[0059] Two installation sliding platforms 32 symmetrically and parallelly distributed at the bottom inside the shock-absorbing chassis 2, which are used to support and fix the chevron articulated frame 31;

[0060] Several chevron articulated frames 31 are supported between the tops of the two side sliding platforms 32 and the bottom of the installation plate 5;

[0061] An angle adjustment mechanism 33 is distributed inside the bottom surface of the shock-absorbing chassis 2, driving the relative movement of the two side installation sliding platforms 32 to adjust the top angle of the chevron articulated frame 31 to achieve precise adjustment of the jacking mechanism 3.

[0062] The angle adjustment mechanism 33 includes the following structure:

[0063] Two screw rod sleeves 333 are correspondingly connected to the center positions at the bottoms of the two side installation sliding platforms 32, which are used to support and guide the movement of the installation sliding platforms 32;

[0064] Two driving lead screws 332 are correspondingly threadedly connected inside the lead screw sleeves 333 on both sides. By rotating the driving lead screws 332, the operation of adjusting the distance between the mounting sliders 32 on both sides is realized, and then the operation of adjusting the top angle of several chevron articulated frames 31 is realized. The smaller the angle, the higher the jacking height of the mounting plate 5, and vice versa. When the working shock-absorbing assembly 6 on the top of the mounting plate 5 is jacked up and supported on the bottom surface of the double-suction pump mounting table 7, the conversion from the transfer shock-absorbing mode to the working shock-absorbing mode is completed;

[0065] A double-shaft reduction motor 331 is located at the central position between the two driving lead screws 332 and is respectively connected to the inner ends of the two driving lead screws 332 to drive the rotation of the driving lead screws 332.

[0066] The working shock-absorbing assembly 6 includes the following structures:

[0067] A shock-absorbing backing plate 61 distributed on the top surface of the mounting plate 5 is used to support the double-suction pump mounting table 7 and absorb vibrations in the working shock-absorbing state;

[0068] Four spring dampers 62 are correspondingly installed at the four corner ends of the top surface of the mounting plate 5. Through the elastic deformation of the springs and the damping effect of the dampers, the absorption and attenuation of vibrations are realized.

[0069] The transfer shock-absorbing assembly 8 includes the following structures:

[0070] A sliding column 81 is distributed inside the first mounting groove 21 at the same position and is used to support the connecting sleeve 82 and the buffer spring 83;

[0071] A connecting sleeve 82 is slidably sleeved on the sliding column 81, and the inner wall of the connecting sleeve 82 is fixedly connected to the same side of the double-suction pump mounting table 7;

[0072] A buffer spring 83 is sleeved on the sliding column 81, and its top end is supported on the lower end surface of the connecting sleeve 82. Through the elastic deformation of the spring, the buffering and absorption of the bumpy vibrations during the transfer of the device are realized.

[0073] Second mounting grooves 22 are provided at the centers of the front and rear side walls inside the shock-absorbing chassis 2, and guiding assemblies 9 connected to the double-suction pump mounting table 7 are installed inside the second mounting grooves 22. The function of the guiding assembly 9 is to guide and support the movement of the double-suction pump mounting table 7 inside the shock-absorbing chassis 2 to ensure its stability and accuracy.

[0074] The guiding assembly 9 includes the following structures:

[0075] A guiding column 91 is installed inside the second mounting groove 22 and is used to support and guide the movement of the double-suction pump mounting table 7;

[0076] A guiding sleeve 92 is slidably sleeved on a guiding column 91. The inner pipe wall of the guiding sleeve 92 is fixedly connected to the center of the side of the double-suction pump mounting table 7, realizing precise guiding between the double-suction pump mounting table 7 and the shock-absorbing chassis 2.

[0077] Four corner ends at the inner bottom of the shock-absorbing chassis 2 are each provided with a telescopic support column 4. The tops of the four telescopic support columns 4 respectively support at the four corner ends of the bottom of the mounting plate 5. This design can improve the bottom stability during the lifting process of the mounting table 5 and during the support operation.

[0078] Working principle

[0079] The shock-absorbing double-suction pump specifically includes two modes: working shock absorption and moving shock absorption to adapt to different usage requirements and environments. The working shock absorption mode mainly realizes the absorption and weakening of the vibration generated during the operation of the double-suction pump and the absorption of the bumpy vibration during the transfer of the device through the working shock absorption component 6 and the transfer shock absorption component 8. The working shock absorption mode is switched through the jacking mechanism 3.
