Description

Technical Field

[0001] The utility model belongs to the technical field of concrete vibrators, and in particular relates to a concrete vibrator with multiple vibration frequencies. Background Art

[0002] Existing concrete vibrators usually only provide a single vibration frequency, which is difficult to adapt to different construction environments and process requirements. During the concrete construction process, different concrete ratios and pouring conditions require different vibration frequencies to ensure the density and uniformity of the concrete. Traditional concrete vibrators lack flexibility and cannot meet diverse vibration requirements, which can easily lead to the failure to effectively discharge concrete bubbles, affecting the quality and durability of the concrete structure. In addition, the design of existing vibrators is usually relatively simple, lacking the necessary frequency display and adjustment functions. It is difficult for operators to intuitively understand and control the working status of the vibrator during use, which affects the construction effect.

[0003] In order to solve the above problems, the utility model provides a concrete vibrator with multiple vibration frequencies. By setting a vibration frequency adjustment button and a vibration frequency display screen, the operator can conveniently adjust and monitor the vibration frequency according to the construction requirements. At the same time, the device adopts a detachable concrete vibration column design, which allows for quick replacement when the requirements are not met, thereby improving the adaptability and practicality of the equipment. These improvements are intended to improve the quality and efficiency of concrete construction and meet the construction requirements under different working conditions.

[0004] The existing concrete vibration equipment (publication number: CN209579917U) generally has the following problems during use:

[0005] 1. Lack of a structure that can adjust the vibration frequency: Concrete quality issues: If the vibration frequency cannot be adjusted according to the specific construction conditions, the bubbles in the concrete may not be fully discharged, which in turn affects the density and strength of the concrete, and ultimately leads to substandard structural quality. Low construction efficiency: The fixed vibration frequency may not be able to adapt to different concrete ratios and pouring conditions, resulting in poor vibration effects, requiring longer time or multiple vibrations to achieve the desired effect, reducing construction efficiency. Increased equipment loss: Since the vibration frequency is not adjustable, the equipment may run for a long time at an inappropriate frequency, increasing the wear and failure risk of mechanical parts and shortening the service life of the equipment. Therefore, a concrete vibrator with adjustable vibration frequency is urgently needed.

[0006] 2. When the vibration frequency of the vibrating rod cannot be met, it is inconvenient to replace the concrete vibration column: Low construction efficiency: Difficult maintenance: If the vibrating rod is not easy to disassemble, it will become very difficult when it needs to be cleaned, repaired or replaced. This may cause the equipment to be in a non-working state for a long time, affecting the construction progress. Reduce equipment life: The vibrating rod is the part of the concrete vibrator that often withstands high-intensity use. The design that is not easy to disassemble may result in the failure to replace the worn vibrating rod in time, thereby accelerating the wear and aging of the entire equipment. Construction quality issues: The effect of the vibrating rod directly affects the density and uniformity of the concrete. If the vibrating rod suitable for a specific task cannot be replaced due to inconvenience in disassembly, it may lead to poor concrete pouring quality, such as voids and uneven structures, which will affect the stability and safety of the final structure, so there is an urgent need for a concrete vibrator that is easy to replace the vibrating rod.

[0007] 3. Lack of structure to display vibration frequency: Inaccurate vibration frequency: Operators cannot monitor the vibration frequency in real time and can only operate based on experience or feeling, which may lead to inaccurate vibration frequency, thus affecting the density and uniformity of concrete. Low construction efficiency: Operators need to spend more time and energy to adjust the vibrator to achieve the ideal vibration effect, which reduces construction efficiency and prolongs the construction period. Therefore, a concrete vibrator that can display the vibration frequency is urgently needed. Utility Model Content

[0041] Running logic and implementation:

[0042] By setting the vibration frequency adjustment button, the operator can flexibly adjust the vibration frequency according to different concrete types, pouring thickness and environmental conditions (such as temperature and humidity). This enables the equipment to adapt to a wider range of construction scenarios, thereby optimizing the construction process. The appropriate vibration frequency can effectively help the bubbles in the concrete to be discharged, thereby increasing the density of the concrete. By adjusting the vibration frequency, it is possible to ensure that the concrete achieves the best density effect under various conditions, which is crucial to improving the bearing capacity and durability of the structure. The ability to quickly adjust the vibration frequency means that when faced with different construction stages or emergencies, you can respond quickly, avoiding time waste due to equipment adjustments and improving construction efficiency.

[0043] The concrete vibrating column and the vibrating motor can be connected by setting a connecting fixing ring and fixing bolts. When replacement is required, the fixing bolts are removed, the connecting fixing ring is disassembled, and the two are separated for replacement. The connecting fixing ring and fixing bolt design allow for quick and easy removal and installation of the concrete vibrating column and the vibrating motor.

For example, different lengths or diameters of vibrating columns may be required for different thicknesses or types of concrete layers, and these changes can be easily accommodated with this design. Since replacing parts becomes easy and quick, the reliance on professional repair services is reduced, thereby reducing maintenance costs. In addition, timely replacement of damaged parts can prevent further equipment damage and avoid higher repair costs.

[0044] By setting the vibration frequency display screen, the operator can intuitively see the current vibration frequency, so as to accurately adjust the vibrator to match different construction needs. This precise control helps to ensure the uniformity and density of concrete and reduce human errors. The instant feedback provided by the display allows the operator to adjust the vibration frequency according to the real-time needs during the construction process.

[0045] Overall operation process: The operator starts the equipment through the vibrator switch, adjusts the vibration frequency through the vibration frequency adjustment button, and observes the reading on the vibration frequency display screen in real time to ensure that the vibration frequency meets the current construction requirements. The vibration motor drives the motor transmission column, and transmits power to the vibrating eccentric column through the plug-in connection of the cross protrusion and the cross groove at the top of the eccentric column to produce the required vibration effect. The vibration frequency display screen provides real-time vibration frequency readings, and the operator can make precise adjustments as needed to ensure the uniformity and density of the concrete. When the vibration column needs to be replaced, the operator removes the fixing bolts, disassembles the connecting fixing ring, and quickly replaces the concrete vibration column to ensure the efficient operation of the equipment and adapt to different construction needs.
