Technical Field
[0001] A magnetic adsorption-type concrete construction vibration compaction system belongs to the field of engineering machinery technology. Background Technology
[0002] This technology is primarily applicable to the construction of the main structure of compressed air energy storage chambers. The structure consists of three parts: a sealing layer, secondary lining, and initial support. The construction sequence is as follows: initial support (composed of steel mesh, arch frame, anchor bolts, and shotcrete) → sealing layer (mainly composed of assembled steel tiles) → secondary lining (reinforced concrete structure). The main construction process includes: steel tile transportation, steel tile assembly and longitudinal seam welding (assembling individual steel tiles into a ring lining), large section assembly and circumferential weld welding (welding multiple ring linings into a whole), large section transfer and positioning, installation of internal and external supports for the secondary lining, and pouring of the lining concrete. During the lining concrete pouring stage, the poured concrete must be vibrated and compacted to ensure the density of the concrete structure and the quality of the lining. This is crucial for ensuring the construction quality of the chamber meets design requirements and is key to guaranteeing the long-term safe and stable operation of the entire chamber. However, in the process of pouring lining concrete, there is currently no vibration compaction system for vibrating and compacting the poured concrete. There is an urgent need to innovate and develop a magnetic adsorption type concrete construction vibration compaction system to meet the urgent needs of the compressed air energy storage field. In addition, the system can also be applied to other applications. Summary of the Invention
[0003] The purpose of this invention is to develop an innovative magnetic adsorption-type concrete construction vibration compaction system to meet the urgent needs in the field of compressed air energy storage. It is also suitable for occasions where frequent disassembly and assembly of vibrators or other formwork exteriors are not suitable for secondary processing.
[0004] The technical solution of this invention is as follows: The system includes several vibrator electromagnet assemblies magnetically attached to a support template, a frequency converter control cabinet, power supply cables for the assemblies, and power supply cables for the frequency converter cabinet; the vibrator electromagnet assembly consists of a vibrator body, straps, eye bolts, electromagnet bolts connecting the vibrator body to the electromagnet, and an electromagnet; the frequency converter control cabinet consists of a frequency converter, a DC power supply, a rotary switch, and an air switch; the power supply cable for powering the frequency converter in the frequency converter control cabinet and the power supply cable for powering the DC power supply do not use the same power line.
[0005] The beneficial effects of this invention are: it makes up for the lack of a vibration compaction system for compacting poured concrete in the current construction of compressed air energy storage chambers, effectively solves the problem of the main structure construction of compressed air energy storage chambers, meets the urgent needs in the field of compressed air energy storage, and realizes the mechanization and intelligentization of concrete vibration compaction construction in compressed air energy storage chambers, reduces the labor intensity of workers, has high work efficiency, good compaction effect, novel design, reasonable structure, flexible operation, convenient installation, and safety and reliability. In addition, it also provides a reliable and usable vibration device for occasions where frequent disassembly and assembly of vibrators or other formwork exteriors are not suitable for secondary processing.

[0009] The details and working process of the present invention are described in detail with reference to the accompanying drawings. The system includes several vibrator electromagnet assemblies 1 magnetically attached to the support template 4, a frequency converter control cabinet 2, power supply cables 3 for the assemblies, and power supply cables 5 for the frequency converter cabinet. The vibrator electromagnet assembly 1 consists of a vibrator body 1-1, a strap 1-2, a lifting eye screw 1-3, an electromagnet 1-4, and bolts 1-5 connecting the vibrator body to the electromagnet. The frequency converter control cabinet 2 consists of a frequency converter 2-1, a DC power supply 2-2, a rotary switch 2-3, and an air switch 2-4. The power supply cable 5-1 supplying power to the frequency converter 2-1 in the frequency converter control cabinet 2 and the power supply cable 5-2 supplying power to the DC power supply 2-2 do not use the same power supply to ensure the reliability of the electromagnet power supply.
[0010] According to the design requirements of the compressed air energy storage chamber, the concrete structure uses self-compacting concrete with a permeability grade of P12 and a strength grade of C40. The P12 permeability grade requires that the hardened concrete can withstand a water pressure of 1.2 MPa without permeation. The core of self-compacting concrete is "high cementitious material content, high sand ratio, high water-reducing agent content" and "low water-cement ratio." According to the JGJ / T283-2012 standard, the C40 self-compacting concrete mixture needs to achieve: a slump spread of 550mm-700mm and a T50 flow time of 2-5 seconds. In addition, this system uses a high-frequency attached vibrator; therefore, a frequency converter 2-1 is required in the system. Frequency converter 2-1 and DC power supply 2-2 are both installed in the frequency converter control cabinet 2. The high-frequency attached vibrator used has a high vibration frequency of 100Hz-110Hz and a small amplitude of 0.8mm-1.0mm, which provides good compaction effect for concrete structures such as compressed air energy storage chambers.
[0011] The vibrator body 1-1 and the electromagnet 1-4 are connected by the vibrator body connecting electromagnet bolt 1-5. When the electromagnet 1-4 is energized, it is magnetically attracted to the support template 4.
[0012] The power supply cable 3 for the vibrator electromagnet assembly 1 is tied to the eye bolts 1-3 of the main unit and the next vibrator electromagnet assembly 1, ensuring that the outlet of the vibrator body 1-1 and the power supply cable 3 itself are not subjected to excessive self-weight load; the vibrator body 1-1 is attached to the support template 4 by the electromagnet 1-4 and is fixed to the binding strap 1-2 by the eye screws 1-3, preventing the vibrator power cable 3-1 and the electromagnet power cable 3-2 from swinging and being damaged at the joint due to excessive self-weight.
[0013] After the concrete lining of the compressed air energy storage chamber is poured, the system is installed in place. Several vibrator electromagnet assemblies 1 are installed on the support template 4 in sequence according to the vibration compaction requirements. After checking that the frequency converter control cabinet 2 is correct, the DC power supply 2-2 is powered on first, and then the rotary switch 2-3 is turned on. The electromagnet 1-4 is activated, which firmly magnetizes the vibrator electromagnet assembly 1 onto the support template 4. Then, the air switch 2-4 of the system is pressed to power the frequency converter 2-1. Several vibrator bodies 1-1 generate high-frequency vibration to vibrate and compact the concrete, eliminate air holes in the concrete mixture, improve the strength of the concrete structure, and shorten its setting time. After the concrete in the support formwork 4 of this machine position has been vibrated and compacted to the required standard, the air switch 2-4 is turned off, and all vibrator bodies 1-1 stop running. Then the rotary switch 2-3 is turned off, and the electromagnets 1-4 also stop working in sequence. The vibrator electromagnet assembly 1 is disassembled one by one and installed on the support formwork 4 of the next machine position. The above process is repeated, and so on, to complete the vibration compaction operation of the concrete lining structure of the entire chamber in sequence.
[0014] The beneficial effects of this invention are: it makes up for the lack of a vibration compaction system for compacting poured concrete in the current construction of compressed air energy storage chambers, effectively solves the problem of the main structure construction of compressed air energy storage chambers, meets the urgent needs in the field of compressed air energy storage, and realizes the mechanization and intelligentization of concrete vibration compaction construction in compressed air energy storage chambers, reduces the labor intensity of workers, has high work efficiency, good compaction effect, novel design, reasonable structure, flexible operation, convenient installation, and safety and reliability. In addition, it also provides a reliable and usable vibration device for occasions where frequent disassembly and assembly of vibrators or other formwork exteriors are not suitable for secondary processing.
