Description

Technical Field

[0001] This utility model relates to the field of equipment shock absorber and shock absorber base, and in particular to a fully flexible vertical pipeline water pump shock absorber base, which is suitable for various pipeline water pumps, and especially suitable for use in various underground heating boiler room heat exchange stations. Background Technology

[0002] Vibration is unavoidable in industrial production when pumps and other moving equipment are in operation. This vibration not only causes great damage to connected pipelines but also generates noise pollution in the surrounding environment, especially since vibration can propagate through building structures. Traditional methods for pump vibration reduction typically involve placing rubber or spring pads between the equipment foundation and the pump, and then securing the three together with anchor bolts.

[0003] However, because anchor bolts clamp the water pump and the foundation with rubber or spring washers, and the connection between the anchor bolts and the water pump is rigid after tightening, it cannot be completely flexible. This causes vibrations to be transmitted to the foundation through the rigid connection, and then amplified outwards through the walls and other structures. Currently, many cases have shown that even with the installation of vibration damping pads, vibration noise still exists. Therefore, how to reduce or even eliminate vibration noise has become an urgent problem to be solved. Utility Model Content

[0017] Figure 2 for Figure 1 The image shows a top view of a fully flexible vertical pipeline pump shock absorber. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The structure of this utility model will now be described. The fully flexible vertical pipeline water pump shock absorber provided by this utility model includes: a mounting surface 1 for fixing the water pump, a transmission frame 2, an upper sealing plate 3, a horizontal spring 4, a vertical spring 5, a side frame 6, and a lower sealing plate 7. The transmission frame 2 is composed of an upper square steel plate 21, a circular steel pipe 22, and a lower square steel plate 23.

[0020] like Figure 1 As shown:

[0021] Both the upper sealing plate 3 and the lower sealing plate 7 are square steel plates made of Q235 carbon steel. The upper sealing plate 3 has a central circular hole with a diameter larger than the circular steel pipe 22, allowing the circular steel pipe 22 of the transmission frame 2 to pass through the central hole, enabling the transmission frame 2 to reciprocate between the upper sealing plate 3 and the lower sealing plate 7. The side frame 6 is made of channel steel welded together along its side, with the ends of the two welded channel steel sections connected to form a frame. This frame is then installed on the upper sealing plate 3 and the lower sealing plate 7. The side frame 6 is directly welded to the lower sealing plate 7 and fastened to the upper sealing plate 3 with bolts. The lower sealing plate 7 is larger than the upper sealing plate 3, and holes are provided along its edge. Anchor bolts are used to rigidly fix the lower sealing plate 7 to the concrete surface through these holes.

[0022] The transmission frame 2 will now be described:

[0023] The transmission frame 2 is an "I"-shaped structure composed of a central circular steel pipe 22, an upper square steel plate 21, and a lower square steel plate 23. It serves to transmit the vibrations generated by the water pump mounted on the mounting surface 1 during operation to the horizontal and vertical springs 5, thus distributing the force and transmitting vibration waves. Specifically, the circular steel pipe 22 is a Q235 carbon steel spiral welded pipe, and the upper and lower square steel plates 21 and 23 are made of 10mm thick Q235 carbon steel plates. The circular steel pipe 22 and the upper and lower square steel plates 23 are all welded together. The upper square steel plate 21 is rigidly fixed to the mounting surface 1 by bolts, while the lower square steel plate 23 is restrained and pushed / pulled by the horizontal spring 4 and the vertical spring 5.

[0024] This utility model achieves a flexible connection between the lower square steel plate 23 and the upper and lower sealing plates 7 by setting several vertical springs 5 ​​and horizontal springs 4. Now combined with Figure 1 and Figure 2 The arrangement of the vertical spring 5 and the horizontal spring 4 is explained below:

[0025] The vertical spring 5 is symmetrically mounted on both sides of the lower square steel plate 23, with respect to its upper and lower surfaces, and evenly distributed along the edges of the lower square steel plate 23. For example... Figure 1 The following example illustrates the installation of eight (four sets) vertical springs 5. The lower square steel plate 23 serves as the dividing line, with four springs installed at each of the four corners of the upper and lower surfaces of the lower square steel plate 23. Specifically, each pair of vertical springs 5 ​​is installed symmetrically along their central axes. The ends of the vertical springs 5 ​​installed on the upper surface of the lower square steel plate 23 are connected to the lower surface of the upper sealing plate 3, and the ends of the vertical springs 5 ​​installed on the lower surface of the lower square steel plate 23 are connected to the upper surface of the lower sealing plate 7, allowing the transmission frame 2 to reciprocate through the central circular hole.

[0026] Each side frame 6 has a bolt ring installed at the center of its inner side surface. This bolt ring is used to fix the horizontal spring 4. There are four sets of horizontal springs 4. During installation, one end of each spring is hooked onto the fixing piece on the upper surface of the lower square steel plate 23, and the other end is hooked onto the bolt ring. During installation, the tension of the horizontal spring 4 is adjusted by rotating the adjusting bolt on the bolt ring.

[0027] Both the vertical spring 5 and the horizontal spring 4 serve as buffering and resetting functions. According to the nature of the force they are subjected to, they are both compression springs and are both made of helical steel. The vertical spring 5 is a flat-headed, hookless industrial spring, while the horizontal spring 4 is a double-headed, hooked industrial spring.

[0028] The present invention will now be described in conjunction with specific application scenarios:

[0029] After the water pump is installed on the mounting surface 1, its downward gravity and the upward force of the vertical spring 5 are balanced. The force on the vertical spring 5 is then transmitted to the ground through the lower sealing plate 7 to achieve a balanced state.

[0030] When the water pump is not running, both the horizontal spring 4 and the vertical spring 5 are in a stretched and ready-to-reset state; when the water pump is running, the horizontal spring 4 and the vertical spring 5 are used to buffer horizontal vibration and vertical vibration, respectively.

[0031] When the water pump is running, the vibrations generated are all transmitted to the rigidly fixed mounting surface 1 and transmission frame 2. At this time, the horizontal spring 4 absorbs the lateral vibration waves, and the vertical spring 5 absorbs the vertical vibration waves. Since the lower square steel plate 23 of the transmission frame 2 is connected to the upper sealing plate 3, the side frame 6, and the lower sealing plate 7 by spring restraint and push-pull, without any other rigid connection, the vibration will not be transmitted to the ground, thus achieving the purpose of complete vibration reduction.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
