Description

Technical Field

[0001] This utility model relates to the field of explosion-proof pump support technology, specifically to a vibration reduction and noise reduction support for an explosion-proof pump in the petroleum and petrochemical industry. Background Technology

[0002] Explosion-proof pumps for the petroleum and petrochemical industry are specially designed for the safe transport and handling of various chemicals in flammable and explosive environments. Their main function is to transport liquids in flammable and explosive locations such as petrochemical plants, ensuring site safety and preventing leaks that could cause environmental pollution and harm. The pump's support frame plays a crucial role in practical applications, providing a stable platform to support and secure the pump. Through proper design, the pump support frame can effectively distribute the pump's weight and transfer it to the ground or foundation structure. However, existing supports for explosion-proof pumps in the petroleum and petrochemical industry still have the following shortcomings:

[0003] 1. Existing supports lack effective shock absorption devices. During the operation of explosion-proof pumps in the petroleum and petrochemical industry, the pumps will vibrate, causing the supports to sway. After long-term use, this will affect the stability of the supports, thereby reducing their service life and making them prone to danger.

[0004] 2. When explosion-proof pumps and supports in the petroleum and petrochemical industry vibrate, they will generate significant noise, which will have a certain impact on the work of on-site personnel. Furthermore, prolonged exposure to noise can also pose certain health risks to workers. Utility Model Content

[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0029] Referring to the attached drawings, a vibration damping and noise reduction bracket for an explosion-proof pump in the petroleum and petrochemical industry includes a support base 1. A support platform 16, a soundproof enclosure 15, a fixed enclosure 12, and a lifting electric push rod 6 are fixed on the support base 1. The support platform 16 has a placement groove and a limiting horizontal plate 21. A shock-absorbing rubber plate 17 is fixed in the placement groove. A shock absorber 18 is installed on the shock-absorbing rubber plate 17. A support plate 19 is fixed to the top of the shock absorber 18. The support plate 19 is connected to the explosion-proof pump mounting platform 10 via a short support column 3. The side of the support plate 19 extends into the limiting groove 2 and is located on the limiting rubber strip 20. The limiting groove 2 is located inside the top side of the limiting horizontal plate 21. The support platform 16 is surrounded by soundproof enclosure panels 15. A top soundproof panel 14 is fixed to the top of the soundproof enclosure panel 15. The top soundproof panel 14 has a through hole 13, through which a short support column 3 passes. The soundproof enclosure panel 15 is surrounded by a fixed enclosure panel 12. The fixed enclosure panel 12 has a lifting groove 4. The lifting groove 4 has a side sound-absorbing panel 7, a back sound-absorbing panel 9, and a front outer sound-absorbing panel 25. The top of the side sound-absorbing panel 7 is fixed to a top plate 5. The top plate 5 is also fixedly connected to the top of the lifting electric push rod 6. A second translation electric push rod 29 is fixed to the top plate 5. The second translation electric push rod 29 is connected to the top sound-absorbing panel 8.

[0030] There are two front external sound-absorbing panels 25, and each front external sound-absorbing panel 25 is provided with a receiving groove 24. A support 22 is fixed in the receiving groove 24. A first translation electric actuator 23 is fixed on the support 22. The first translation electric actuator 23 is connected to the front internal sound-absorbing panel 26. The front internal sound-absorbing panel 26 is provided with a first semi-circular notch 27 on its side. The two first semi-circular notches 27 can be closed to form a circle, and the pump inlet pipe of the petroleum and petrochemical explosion-proof pump can pass through it.

[0031] The number of the top sound-absorbing panels 8 is two. Each top sound-absorbing panel 8 has a second semi-circular notch 28 on its side. The two second semi-circular notches 28 can be enclosed to form a circle, and the pump outlet pipe of the petroleum and petrochemical explosion-proof pump can pass through it.

[0032] The back-side sound-absorbing panel 9 is fixed between one side of the two side sound-absorbing panels 7, and the other side of each side sound-absorbing panel 7 is fixedly connected to the front outer sound-absorbing panel 25.

[0033] Rubber support washers 11 are fixed around the bottom of the explosion-proof pump mounting platform 10, and the bottom of the rubber support washers 11 is located on the top sound insulation plate 14.

[0034] The limiting rubber strip 20 is fixed in the limiting groove 2.

[0035] There is more than one shock absorber 18, and they are evenly distributed on the shock-absorbing rubber plate 17.

[0036] Both the second translation electric actuator 29 and the first translation electric actuator 23 are wirelessly connected to an external remote controller, and the two second translation electric actuators 29 are connected to the same control switch, as are the two first translation electric actuators 23.

[0037] When using this explosion-proof pump vibration reduction and noise reduction bracket for petroleum and petrochemical industries, first activate the lifting electric actuator 6. The lifting electric actuator 6 raises the top plate 5, causing the side sound-absorbing plate 7 to rise. The side sound-absorbing plate 7 then raises the back sound-absorbing plate 9 and the front outer sound-absorbing plate 25 simultaneously. After the side sound-absorbing plate 7, back sound-absorbing plate 9, and front outer sound-absorbing plate 25 are all raised, simultaneously activate the two first translation electric actuators 23. The first translation electric actuators 23 push the front inner sound-absorbing plate 26 outwards. When the outer edges of the two front inner sound-absorbing plates 26 are in contact, the two first semi-circular notches 27 will... The inlet pipe of the petrochemical explosion-proof pump is surrounded, and then two second translation electric actuators 29 are activated simultaneously. The second translation electric actuators 29 will push the top sound-absorbing plate 8 to move outward. When the outer edges of the two top sound-absorbing plates 8 are in contact, the two second semi-circular notches 28 can surround the outlet pipe of the petrochemical explosion-proof pump. At this time, the side sound-absorbing plate 7, the back sound-absorbing plate 9, the front outer sound-absorbing plate 25, the front inner sound-absorbing plate 26 and the top sound-absorbing plate 8 can absorb, reflect and block the noise generated by the petrochemical explosion-proof pump and the explosion-proof pump mounting platform 10, effectively reducing the noise at the working site.

[0038] When the explosion-proof pump in the petroleum and petrochemical industry is running, the explosion-proof pump mounting platform 10 will vibrate. The rubber support washer 11 at the bottom of the explosion-proof pump mounting platform 10 will reduce the vibration generated by the explosion-proof pump mounting platform 10 and play a certain role in shock absorption. At the same time, some of the vibration generated by the explosion-proof pump mounting platform 10 can also be transmitted to the support plate 19 through the short support column 3. Since the shock absorber 18 and the shock-absorbing rubber plate 17 are set under the support plate 19, the shock absorber 18 and the shock-absorbing rubber plate 17 will play a good role in shock absorption, greatly reducing the vibration experienced by the support plate 19. At the same time, the limiting rubber strips 20 on both sides of the support plate 19 will also reduce some of the vibration and improve the stability of both sides of the support plate 19, thereby improving the overall stability of the support plate 19.

[0039] When the support plate 19 generates noise due to vibration, the top sound insulation plate 14 and the sound insulation enclosure 15 will absorb, reflect and block the noise generated by the support plate 19, further reducing the noise at the work site.

[0040] In this invention, the explosion-proof pump mounting platform 10 is fixedly connected to the support plate 19 via a short support column 3. A shock-absorbing rubber plate 17 and a shock absorber 18 are provided below the support plate 19, which can enhance the shock absorption effect of the explosion-proof pump mounting platform 10 and the support plate 19, reduce the vibration that occurs when the explosion-proof pump mounting platform 10 and the support plate 19 are in use, improve the stability of the explosion-proof pump mounting platform 10 and the support plate 19 during use, and at the same time reduce the noise generated by the vibration of the explosion-proof pump mounting platform 10 and the support plate 19.

[0041] In this utility model, a rubber support washer 11 is installed on the bottom end of the explosion-proof pump mounting platform 10, which further improves the shock absorption effect and stability of the explosion-proof pump mounting platform 10 during use; and limiting rubber strips 20 are set on the lower sides of the two sides of the support plate 19, which can further improve the shock absorption effect and stability of the support plate 19 during use.

[0042] In this utility model, a top soundproof panel 14 and a soundproof enclosure panel 15 are provided, which can absorb, reflect and block the noise generated by the support plate 19, effectively reducing the transmission of noise and improving the working environment of the staff on site.

[0043] In this utility model, the side sound-absorbing plate 7, the top sound-absorbing plate 8, the back sound-absorbing plate 9, the front outer sound-absorbing plate 25, and the front inner sound-absorbing plate 26 can absorb, reflect, and block the noise generated by the explosion-proof pump mounting platform 10 and the petroleum and petrochemical explosion-proof pump, further reducing the spread of noise and improving the working environment for staff on site.

[0044] In this invention, the top sound-absorbing plate 8 can be moved under the action of the second translation electric push rod 29, and the front inner sound-absorbing plate 26 can be moved under the action of the first translation electric push rod 23, which is beneficial for the maintenance and upkeep of the petroleum and petrochemical explosion-proof pump.

[0045] In this utility model, the side sound-absorbing plate 7, the top sound-absorbing plate 8, the back sound-absorbing plate 9, and the front outer sound-absorbing plate 25 can be raised and lowered under the action of the lifting electric push rod 6, which is convenient for use and storage.
