Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment support and adjustment technology, and in particular to an adjustable bracket for a small vertical water pump. Background Technology

[0002] In modern construction engineering, pump stations are crucial infrastructure, and the rational utilization of their space is paramount. With rapid urbanization and increasing scarcity of construction land, how to accommodate more equipment within limited pump station space has become a research hotspot. Vertical water pumps, due to their unique structural advantages, can effectively improve the space utilization of pump stations and are gradually being widely used in various projects. These pumps not only save floor space but also allow for a more compact and rational layout of the pump station, playing a positive role in improving the efficiency and stability of the entire water supply system. Simultaneously, they align with current trends in energy conservation and environmental protection, contributing to the sustainable development of the construction industry.

[0003] In the installation of small vertical water pumps, there are several mature methods in the industry for adjusting the pump body's height, level, and verticality, as well as ensuring a stable overall installation. Traditionally, wedge shims are used to adjust the pump body's height, level, and verticality. Construction workers select appropriate sizes of wedge shims based on the actual situation, continuously adjusting their position and quantity to achieve the required installation accuracy. Additionally, secondary grouting is typically performed directly after the pump is in place to fill the gap between the pump and the foundation, enhancing the equipment's stability. Furthermore, to reduce vibrations generated during pump operation, shock-absorbing rubber pads are usually placed between the pump and the foundation.

[0004] However, existing installation methods have significant shortcomings. Because the pump body and motor of a small vertical water pump are integrated, with the motor located on top of the pump body, the center of gravity is asymmetrical. During hoisting, positioning, and adjustment, the pump is prone to tipping over, potentially leading to equipment damage and personal injury. Furthermore, the adjustment method using inclined shims is cumbersome and inefficient. Additionally, the small gap between the pump and the foundation grouting layer easily causes incomplete secondary grouting, affecting the pump's installation quality. Simultaneously, the shock-absorbing rubber pads are easily covered by cement slurry, greatly complicating the accuracy of pump installation and adjustment. Utility Model Content

[0005] This application provides a small, adjustable bracket for a vertical water pump, which facilitates quick installation and height adjustment of the pump, and increases shock absorption.

[0006] This application provides a small, adjustable vertical water pump bracket, which adopts the following technical solution:

[0007] A small vertical adjustable water pump bracket includes an upper structure and a lower structure. The upper structure is a quick-installation frame structure for adjusting the height of the water pump, and the lower structure is a quick-installation frame structure for anchor bolts. A connecting rod is provided between the upper and lower structures, and the upper and lower structures are connected by a connecting rod. Both the upper and lower structures are provided with height adjustment components to adjust their height relative to the ground. A shock-absorbing transition component is provided in the lower structure.

[0008] By adopting the above technical solution, this utility model designs a small vertical adjustable water pump bracket. In use, the adjustable bracket consists of an upper structure with an adjustable height quick-installation frame for the water pump and a lower structure with a quick-installation frame for anchor bolts, enabling rapid installation of the water pump and anchor bolts. A connecting rod connects the upper and lower structures. Height adjustment components are installed within the upper and lower structures to adjust the bracket's height relative to the ground. The upper structure is fixed to the supporting steel plate by internal expansion bolts to ensure structural stability. A shock-absorbing transition component is installed within the supporting steel plate to provide vibration damping.

[0009] Preferably, the upper structure includes an internal expansion bolt and a mounting plate, wherein the internal expansion bolt is threadedly connected to the upper part of the connecting rod, thereby fixing the upper structure.

[0010] By adopting the above technical solution, the upper structure can be fixed by using the internal expansion bolts and the threaded connection of the upper part of the connecting rod during use, which can ensure the stability of the upper structure, making the structure of the entire small vertical water pump adjustable bracket more reliable and facilitating the stable installation of the water pump.

[0011] Preferably, the internal expansion bolt is provided with an adjustable nut, which allows the position of the mounting plate to be adjusted according to different sizes of water pumps.

[0012] By adopting the above technical solution, the position of the mounting plate can be adjusted by using the adjustable nut on the internal expansion bolt during use, so that the adjustable bracket can be adapted to water pumps of different sizes, thus enhancing the versatility and applicability of the adjustable bracket.

[0013] Preferably, the lower structure includes anchor bolts and a supporting steel plate, and the anchor bolts are threadedly connected to the lower part of the connecting rod.

[0014] By adopting the above technical solution, the anchor bolts of the lower structure are threadedly connected to the lower part of the connecting rod during use, which facilitates the assembly and connection of the lower structure, can stably support the adjustable bracket of the small vertical water pump, and provides a stable foundation for subsequent operations such as height adjustment.

[0015] Preferably, the anchor bolts are equipped with adjustable nuts, and their height can be adjusted by adjusting the nuts on the bolts located at the four corners of the supporting steel plate.

[0016] By adopting the above technical solution, adjustable nuts are installed on the anchor bolts during use. The height of the anchor bolts can be adjusted by using the bolt adjustment nuts set at the four corners of the supporting steel plate, which enables efficient and high-precision adjustment of the pump body elevation and level.

[0017] Preferably, a secondary grouting layer is reserved between the supporting steel plate and the lower anchor bolt fixing frame, and the reserved gap of the secondary grouting layer is 150mm.

[0018] By adopting the above technical solution, a secondary grouting layer of 150mm is reserved between the supporting steel plate and the lower anchor bolt fixing frame during use, so as to avoid the problem of incomplete secondary grouting caused by the small gap between the water pump and the foundation grouting layer.

[0020] By adopting the above technical solution, during use, the whole piece of rubber damping pad of the damping transition component is placed in the central area of ​​the supporting steel plate and fixed to the water pump base by bonding process, which can ensure the independent structure of the damping pad and ensure the damping effect; the rubber damping pad and the central area of ​​the supporting steel plate form a transition connection, which plays a buffering role and prevents the vibration of the water pump from being directly transmitted to the supporting steel plate during operation.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. This utility model relates to a small vertical water pump adjustable bracket, which, by setting height adjustment components in the upper and lower structures and cooperating with adjustable nuts, enables efficient and high-precision adjustment of the pump body elevation and level.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] This utility model discloses an adjustable bracket for a small vertical water pump, such as... Figure 1 As shown, the system includes an upper structure 1, a lower structure 2, a connecting rod 3, a height adjustment component, internal expansion bolts 11, a supporting steel plate 22, and a vibration-damping transition assembly 5. The upper structure 1 and lower structure 2 are connected by the connecting rod 3, and both have internal height adjustment components for adjusting their height relative to the ground. The upper structure 1 is fixed to the supporting steel plate 22 by internal expansion bolts 11. The vibration-damping transition assembly 5 is installed inside the supporting steel plate 22, achieving efficient and high-precision adjustment of the pump body's elevation and level while ensuring effective vibration damping. This is because the height adjustment component allows for flexible adjustment of the support height, making pump installation more precise, while the vibration-damping transition assembly 5 reduces vibration during pump operation.

[0029] Specifically, the upper structure 1 includes internal expansion bolts 11 and mounting plates 12. The internal expansion bolts 11 are adjustable, and their bolts are typically made of high-strength steel, such as alloy steel, which ensures sufficient strength and corrosion resistance. The mounting plates 12 are generally made of metal, such as carbon steel, and their surface is treated with anti-corrosion coating to prevent rust. The mounting plates 12 are often square in shape, with holes in the center for mounting the water pump. The mounting plates 12 can also be replaced with cast iron plates, which offer better rigidity and stability. The internal expansion bolts 11 are threadedly connected to the upper part of the connecting rod 3. By rotating the internal expansion bolts 11, the upper structure 1 can be securely fixed in the appropriate position. The threads on the internal expansion bolts 11 must be precise and smooth to ensure a tight connection.

[0030] Meanwhile, an adjustable nut 4 is provided on the internal expansion bolt 11. The adjustable nut 4 is generally made of brass, which is easy to process and has a certain degree of wear resistance. The adjustable nut 4 can also be replaced with a stainless steel nut. By rotating the adjustable nut 4, the position of the mounting plate 12 can be changed. When the water pump size is small, the nut can be tightened to bring the mounting plate 12 closer to the connecting rod 3, and vice versa. This allows for flexible adjustment according to different sizes of water pumps to meet the installation needs of various water pumps.

[0031] Specifically, the lower structure 2 includes anchor bolts 21 and supporting steel plates 22. Anchor bolts 21 are typically made of coarse-threaded round steel, such as Q235 steel, with hook-shaped heads for better fixation to the foundation. Anchor bolts 21 can be replaced with high-strength bolts, which provide greater preload. Supporting steel plates 22 are generally thick steel plates, such as those around 20mm thick, with smooth, flat surfaces for good contact with the water pump and foundation. Supporting steel plates 22 can also be replaced with cast steel, which offers better integrity and strength. Anchor bolts 21 are threadedly connected to the lower part of the connecting rod 3; by tightening or loosening the anchor bolts 21, the position and height of the lower structure 2 can be adjusted.

[0032] Furthermore, adjustable nuts 4 are provided on the anchor bolts 21. These adjustable nuts 4 are similar to those on the upper structure 1, and share the same material and replaceable parts. The height of the supporting steel plate 22 is adjusted by using the adjustable nuts on the bolts located at the four corners. During installation, construction personnel can precisely rotate the adjustable nuts on the bolts at the four corners based on actual measured height data, thereby achieving fine-tuning of the height of the lower structure 2 and ensuring the pump body's levelness.

[0033] A secondary grouting layer is reserved between the supporting steel plate 22 and the lower anchor bolt 21 fixing frame, with a reserved gap of 150mm. This gap ensures sufficient space for cement grout to flow during secondary grouting, thereby filling densely and enhancing the stability of the equipment. A vibration damping transition component 5 is provided at the center of the supporting steel plate 22, including a rubber vibration damping pad 51 located in the central area of ​​the supporting steel plate 22. The rubber vibration damping pad 51 is a single piece made of natural rubber, which has good elasticity and vibration damping performance. The rubber vibration damping pad 51 can also be replaced with synthetic rubber, such as nitrile rubber, which has good oil resistance and wear resistance. The rubber vibration damping pad 51 is fixed to the water pump base by an adhesive process, such as using a special rubber adhesive, which ensures a firm connection between the rubber vibration damping pad 51 and the water pump base. The rubber vibration damping pad 51 forms a transition connection with the central area of ​​the supporting steel plate 22, effectively isolating the vibration generated during water pump operation and ensuring the vibration damping effect.

[0034] Working Principle: The adjustable bracket for the small vertical water pump in this embodiment, through its reasonable structural design and the use of height adjustment components and adjustable nuts 4, can efficiently and precisely adjust the elevation and level of the pump body. Simultaneously, the reserved secondary grouting layer ensures the compactness of the grouting, enhancing the stability of the equipment. The inclusion of vibration-damping transition components 5 effectively reduces vibration during pump operation, extending the pump's service life. Compared to traditional installation methods, this avoids the risk of pump tipping, improves installation efficiency and quality, and solves many problems existing in the prior art.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
