Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment installation, in particular to an efficient and precise installation structure for the shock absorber base of electromechanical equipment. Background Technique

[0002] With the large-scale development and rapid economic growth of our country, all regions are booming, especially the construction of large and medium-sized cities is changing with each passing day. Due to the high cost of land, construction in various places is developing towards the sky, and high-rise buildings are springing up like mushrooms. It is crucial to isolate vibration, reduce noise, protect the environment and buildings when power equipment is installed upstairs. How to improve the efficient and precise installation of power equipment is a direction to promote and develop the electromechanical equipment installation technology.

[0003] Generally, the installation method of electromechanical equipment such as cooling towers is as follows: The reinforced concrete foundation on the roof or floor is a strip foundation or an integral pier foundation. The consumption of steel bars and concrete materials used is relatively large, and its load on the roof or floor is also relatively large, requiring a high bearing capacity of the roof or floor. Moreover, the construction space under the foundation is small, and it is difficult to connect the water supply and drainage pipes of the cooling tower equipment and install the cable tray of the cooling tower in the later stage; there are errors in the construction of the reinforced concrete foundation, and the foundation is not on the same horizontal plane. When installing shock absorbers, steel plates are often welded on their embedded parts or on their I-beam crossbeam systems to adjust the horizontal error. Its construction is not beautiful and the installation quality cannot meet the requirements; the shock absorber is connected to the horizontal I-beam crossbeam by bolts, and holes are drilled at the connection of the center of the lower flange and the web of the I-beam. The holes in this part have a great influence on the force of the I-beam, and the on-site construction difficulty is large, and the hole quality requirement is high, which is easy to cause poor stability of the I-beam crossbeam system; because the shock absorber is connected to the horizontal I-beam crossbeam by bolts, the position accuracy requirements for the concrete foundation and embedded parts are extremely high. If there are errors, the I-beam crossbeam is prone to eccentric phenomena on the shock absorber, and the shock absorber bolts in the middle part cannot be fixed to the I-beam, and the rigid crossbeam appears to be fixed at both ends and not fixed in the middle; there are a total of three crossbeams arranged at both ends and in the middle of the horizontal I-beam crossbeam system, and the crossbeam arrangement is unreasonable.

[0004] Therefore, there is currently no unified construction method and tools for how to achieve the efficient and precise installation of the base of electromechanical equipment such as cooling towers, improve the construction quality of the shock absorbers of the base of electromechanical equipment such as cooling towers, and ensure the safety of the installation process.

[0023] The features of the present utility model and other related features are further described in detail below through embodiments with reference to the accompanying drawings for the understanding of those skilled in the same industry:

[0024] As Figure 1-8 shown, the markings 1-14 in the figure respectively represent: anti-slip rubber gasket 1, lower shell 2, connection frame 3, vibration isolation spring 4, height adjustment bolt 5, positioning plate 6, preloading bolt 7, upper shell 8, reinforced concrete foundation square column 9, embedded steel plate 10, adjustable horizontal shock absorber 11, I-beam 12, weld 13, cooling tower equipment 14.

[0025] Embodiment: As Figures 1 to 8 shown, the high-efficiency and precise installation structure of the shock absorber base for electromechanical equipment in this embodiment includes the following construction methods:

[0026] a. At the position of the building or structure where electromechanical equipment needs to be installed, such as on the roof or floor, the construction of the reinforced concrete foundation square column 9 is carried out. The construction of the reinforced concrete foundation square column 9 is accurately positioned and lofted, and the error is controlled within 5 mm. The steel bar cage is arranged inside the reinforced concrete foundation square column 9, and the steel bar cage is tied simultaneously with the steel bars on the floor or roof, so that the reinforced concrete foundation square column 9 and the floor or roof form an integral whole.

[0027] b. Embedded steel plate 10 and embedded welding bolts are pre-embedded on the upper part of the reinforced concrete foundation square column 9. The embedded welding steel plates in the foundation are kept at the same elevation, and their installation accuracy is controlled within 5 mm.

[0028] c. After the square reinforced concrete foundation column 9 reaches the design strength, install the anti-slip rubber gasket 1 at the lower part of the adjustable horizontal spring shock absorber 11 on the square reinforced concrete foundation column 9.

[0029] d. Install the adjustable horizontal spring shock absorber 11 on the anti-slip rubber gasket 1. The adjustable horizontal spring shock absorber 11 is bolted to the embedded steel plate 10 and fixed at both ends. The adjustable horizontal spring shock absorber 11 includes a lower shell 2, a connecting frame 3 and an upper shell 8. An installation hole for connecting with the square reinforced concrete foundation column 9 is provided on the lower shell 2. The connecting frame 3 is arranged above the lower shell 2. The connecting frame 3 and the upper shell 2 are connected by a preloading bolt 7, and a shock-absorbing structure composed of a vibration-isolation spring 4, a height-adjusting bolt 5 and a positioning plate 6 is arranged between the connecting frame 3 and the upper shell 8.

[0030] The adjustable horizontal spring shock absorber 11 is equipped with a preloading bolt 7 and a height-adjusting bolt 5. The preloading bolt 7 is equipped through a preloading screw rod. It can avoid the lifting height of the supported mechanical and electrical equipment being effectively controlled when the weight changes after installation, and prevent the relevant pipelines from being damaged due to the lifting of the equipment. The preloading bolt 7 must ensure that it does not touch the outer shell after installation. After applying the load, there is a gap of more than 20m between the upper and lower shells. When the equipment is not level, the height-adjusting screw rod can adjust the height-adjusting bolt 5 to keep the equipment level and has a certain seismic resistance.

[0031] e. Install the horizontally arranged I-beams 12 on the adjustable horizontal spring shock absorber 11. The I-beams 12 on the array-installed adjustable horizontal spring shock absorbers 11 form a horizontal I-beam crossbeam support system. Each I-beam 12 should be welded and fixed to the upper shell 8 of the adjustable horizontal spring shock absorber 11 at each corresponding support. Adjust the height-adjusting bolt 5 of the adjustable horizontal spring shock absorber 11 to adjust its horizontal I-beam crossbeam support system to the same horizontal plane to ensure uniform force on the horizontal I-beam crossbeam support system.

[0032] f. Hoist and install the cooling tower equipment 14 on the horizontal I-beam crossbeam support system. After the cooling tower equipment 14 is hoisted, adjust the height-adjusting bolt 5 to keep the equipment level. After the horizontal adjustment is completed, fix the cooling tower equipment 14 firmly, and carry out the connection of the water supply and drainage pipes of the cooling tower equipment and the installation and layout of the cooling tower cable tray.

[0033] In summary, in this embodiment, an efficient and precise installation of a shock absorber base for mechanical and electrical equipment such as a cooling tower is realized; some problems existing in the installation of the current cooling tower base shock absorber can be solved, so that the installation quality of large mechanical and electrical equipment such as a cooling tower can be effectively guaranteed, with fast construction speed, high installation accuracy, convenient operation, good shock and noise isolation effects, and cost savings at the same time.

[0034] Although the above embodiments have been described in detail with reference to the drawings for the concept and embodiments of the object of the present utility model, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present utility model without departing from the scope defined by the claims, so they will not be elaborated here one by one.
