Description

Technical Field

[0001] The present invention relates to the technical field of vibrators, in particular to an attached pneumatic vibrator and a vibrator group. Background Art

[0002] In construction, concrete pouring, and other related fields, vibrators are critical equipment for ensuring concrete density and quality, and their use is extremely common. With the continuous development of engineering construction and the increasing demands for construction quality, various vibration technologies and equipment are also continuously developing and being applied. From traditional manual vibrators to today's electric and pneumatic vibrators, technology continues to evolve. Different types of vibrators are suitable for different construction scenarios and engineering requirements. For example, in the construction of some large concrete structures, due to the need to process large amounts of concrete, higher efficiency and effectiveness of the vibrator are required, which has prompted the continuous innovation and development of vibration technology.

[0003] There are several problems with existing vibrator technology.

[0004] 1. Difficulty in centralized control

[0005] The control method of vibrators is often not centralized and flexible enough, which brings inconvenience to construction operations. For example, when setting the vibration time and interval, it may not be possible to operate conveniently through a unified control interface, but it may need to be set up in multiple devices or locations. For the control of multiple groups of vibrators, there may be a lack of effective centralized management methods, making it difficult to uniformly set and adjust all vibrators at the same time. This means that in large-scale concrete pouring construction, operators need to operate and set the vibrators one by one. For example, in the concrete pouring project of a large bridge pier, if multiple groups of vibrators are used, due to the lack of centralized control, operators may need to run back and forth at different heights and positions to set the vibration time and interval for each vibrator. The operation is extremely cumbersome and seriously affects construction efficiency. This not only wastes time, but also increases the complexity of the operation and the possibility of errors.

[0006] 2. The vibration time and interval settings are not accurate

[0007] It's difficult to precisely set the vibration time and interval for each set of vibrators, which negatively impacts the vibration results. If the vibration time is too short, bubbles in the concrete won't be fully removed, resulting in insufficient concrete density. If the vibration time is too long, segregation may occur, affecting concrete quality. Similarly, inaccurate vibration intervals can affect vibration uniformity, leading to variations in concrete quality across different locations.

[0008] 3. Inconvenience of single control

[0009] Individually controlling each vibrator group is inconvenient and may require multiple locations. This can create significant challenges for operators in complex construction environments, such as confined spaces or sites with obstacles. Operators may need to bend, climb, or navigate around obstacles to reach each vibrator's operating position, increasing labor intensity and potentially leading to errors and compromising construction quality. Summary of the Invention

[0010] The purpose of the present invention is to provide an attached pneumatic vibrator and a vibrator group to solve the problems existing in the above-mentioned prior art, realize the adjustment of vibration frequency, exciting force and amplitude to meet the requirements of different concrete densities; realize centralized control of each vibrator, and greatly improve construction efficiency.

[0011] To achieve the above-mentioned purpose, the present invention provides the following solution: The present invention provides an attached pneumatic vibrator, comprising a pneumatic vibrator body, a pressure regulating valve, an air source and an air intake pipe, wherein the air source is used to provide a compressed air source for the pneumatic vibrator body, the air source is connected to the pneumatic vibrator body through an air intake pipe, and a pressure regulating valve is provided on the air intake pipe, and the pressure regulating valve is used to adjust the pressure of the compressed air entering the pneumatic vibrator body.

[0012] In one embodiment, the gas source is a compressor, and a shut-off valve is provided on the air inlet pipe between the compressor and the regulating valve.

[0013] In one embodiment, the air intake pipe is made of a rubber pipe.

[0014] In one embodiment, an oil-water separator is installed on the air inlet pipe at the front end of the pneumatic vibrator body, and the oil-water separator is used to separate water and oil in the compressed air.

[0015] In one embodiment, an oil mist collector is further installed on the air inlet pipe, and the oil mist collector is used to add lubricating oil mist to the compressed air entering the pneumatic vibrator body.

[0016] In one embodiment, the pneumatic vibrator body is fixedly mounted on the template via anchor bolts and a mounting base plate; the mounting base plate is welded to the template, and the anchor bolts are used to fasten the pneumatic vibrator body to the mounting base plate.

[0017] The present invention also provides a vibrator group, including the above-mentioned attached pneumatic vibrator, and also including a control cabinet, which is connected to multiple attached pneumatic vibrators. The vibration time and vibration interval of each attached pneumatic vibrator can be centrally set on the touch screen of the control cabinet.

[0018] In one embodiment, one on-site button box is configured for every four of the plurality of attached pneumatic vibrators. When a certain attached pneumatic vibrator needs to be adjusted individually, the operator directly operates on the corresponding on-site button box without the need to set it up through the main control cabinet.

[0019] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0020] The attached pneumatic vibrator and vibrator group of the present invention regulate the compressed air pressure input to the pneumatic vibrator by controlling the pressure of the pressure regulating valve, thereby controlling the gas flow rate. Because different pressures will cause the movement speed and stroke of the piston in the cylinder to change, the vibration frequency, exciting force and amplitude can be adjusted to meet the requirements of different concrete densities. A control main cabinet is provided in the vibrator group, and the vibration time and interval of each group of vibrators can be centrally set on the touch screen, realizing centralized control of each vibrator. The operator only needs to enter the corresponding parameters on the touch screen of the control main cabinet to set all vibrators at the same time, which makes the operation simpler and more efficient. There is no need to run back and forth between the vibrators as before, which greatly improves construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The purpose of the present invention is to provide an attached pneumatic vibrator and a vibrator group to solve the problems existing in the above-mentioned prior art, realize the adjustment of vibration frequency, exciting force and amplitude to meet the requirements of different concrete densities; realize centralized control of each vibrator, and greatly improve construction efficiency.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, the present invention provides an attached pneumatic vibrator, including a pneumatic vibrator body, a pressure regulating valve 3, an air source and an air intake pipe. The air source is used to provide a compressed air source for the pneumatic vibrator body. The air source is connected to the pneumatic vibrator body through an air intake pipe. A pressure regulating valve 3 is provided on the air intake pipe. The pressure regulating valve 3 is used to adjust the pressure of the compressed air entering the pneumatic vibrator body.

[0029] Specifically, the air source is a compressor, and a stop valve 1 is provided on the air intake pipe between the compressor and the regulating valve. The air intake pipe is made of a rubber pipe.

[0030] The pneumatic vibrator body 6, consisting of core components such as a cylinder and piston, is the key to generating vibration. High-pressure gas enters the cylinder, pushing the piston to vibrate axially relative to the cylinder, thereby outputting the vibration. The pressure-regulating valve 3 is used to adjust the pressure of the compressed air to control the vibration parameters of the pneumatic vibrator body 6. The pressure-regulating valve 3 is connected between the air source (compressor) and the pneumatic vibrator body 6 and adjusts the gas pressure by varying the valve opening.

[0031] The compressor provides the entire system with compressed air, compressing it to a certain pressure (0.6 MPa) to meet the operating requirements of the pneumatic vibrator. The air intake duct connects the compressor to the pneumatic vibrator body 6, and the pressure regulating valve 3 to the pneumatic vibrator body 6, transmitting compressed air. The quality and condition of the air intake duct have a significant impact on the quality of the incoming air. For example, it should be kept unobstructed and free of distortion, blockage, and leaks.

[0032] The anchor bolts and mounting base plate are used to fix the vibrator on the template or other equipment. The mounting base plate needs to be fully welded to the equipment. The anchor bolts are used to tighten the vibrator to ensure that the position of the vibrator is stable during the vibration process.

[0033] The oil-water separator 2 is installed on the air intake pipe at the front end of the pneumatic vibrator body 6. Its function is to separate water and oil from the compressed air, preventing water and oil from entering the vibrator's working chamber and affecting the vibrator's normal operation and service life. The oil mist collector 4 is installed on the pipe between the air source and the pneumatic vibrator body 6. It adds lubricating oil mist to the compressed air entering the pneumatic vibrator body 6 to ensure lubrication of the pneumatic components, reduce wear, and extend service life. Because the pneumatic vibrator body 6 requires oil-containing air to operate, the oil mist collector 4 can mix the lubricating oil into the compressed air in mist form. A solenoid valve 5 can also be provided between the oil mist collector 4 and the pneumatic vibrator body 6.

[0034] The control logic of the attached pneumatic vibrator is as follows:

[0035] 1. Pressure regulation to control vibration parameters

[0036] By controlling the pressure of the pressure-regulating valve 3, the compressed air pressure input to the pneumatic vibrator body 6 is adjusted, thereby controlling the gas flow rate. Because different pressures vary the speed and stroke of the piston within the cylinder, the vibration frequency, excitation force, and amplitude can be adjusted to meet the requirements of different concrete densities. For example, when a greater excitation force is required, increasing the pressure of the pressure-regulating valve 3 allows more compressed air to enter the vibrator, pushing the piston to generate a greater impact force.

[0037] 2. Startup sequence control

[0038] First, start the compressor and compress the air to the working pressure value (0.6Mpa). After the compressor starts and reaches the working pressure, open the valve connected to the pneumatic vibrator body 6 to allow compressed air to enter the pneumatic vibrator body 6 to drive the piston to vibrate. This ensures that the pneumatic vibrator body 6 starts at normal working pressure and avoids malfunctions caused by insufficient or unstable pressure.

[0039] 3. Fault handling logic (de-energization)

[0040] If a vibration failure occurs during operation, the system logically resolves it by adding mechanical oil (20#30#) to the pneumatic vibrator body 6. This occurs because insufficient lubrication between the piston and cylinder may occur during operation, increasing friction and affecting the piston's normal vibration. Adding an appropriate amount of mechanical oil improves lubrication conditions and allows the pneumatic vibrator body 6 to resume vibration.

[0041] The compressed air generated by the compressor is first delivered to the pressure regulating valve 3 through the air intake pipe. After the pressure regulating valve 3 adjusts the pressure according to the setting, the compressed air of appropriate pressure is delivered to the pneumatic vibrator body 6 through the air intake pipe to provide power for it. The pneumatic vibrator is fixed to the mounting base plate by anchor bolts, and the mounting base plate is welded to the equipment (such as the formwork for prefabricated concrete components) to ensure that the pneumatic vibrator body 6 can stably transmit vibrations to the equipment and concrete during operation. Before entering the pneumatic vibrator body 6, the compressed air output by the compressor first passes through the oil mist collector 4 to make the air contain oil, and then is delivered to the pneumatic vibrator body 6 through the air intake pipe. An oil-water separator 2 is installed on the air intake pipe at the front end of the pneumatic vibrator body 6 to filter moisture and oil in the compressed air to prevent it from entering the vibrator working chamber.

[0042] The pneumatic vibrator body 6 should not be installed horizontally; its axis should be at a certain angle to the horizontal plane. Vertical installation is more effective. The installation angle needs to be considered during installation to ensure optimal vibration effect and performance. At the same time, ensure that there is a certain amount of space around the pneumatic vibrator body 6 to prevent surrounding objects from blocking the transmission of vibration or affecting its normal operation. For example, avoid pulling on the air intake rubber pipe to prevent the pipe from being subjected to stress and affecting the stability of the vibrator and the quality of the air intake.

[0043] Example 2

[0044] A vibrator group, based on the attached pneumatic vibrator of Example 1, includes multiple attached pneumatic vibrators and a control cabinet. The control cabinet is provided, and the vibration time and interval of each group of vibrators can be centrally set on the touch screen, thereby realizing centralized control of each vibrator. The operator only needs to enter the corresponding parameters on the touch screen of the control cabinet to set all vibrators at the same time, making the operation simpler and more efficient. For example, in the foundation concrete pouring project of a large building, using the attached pneumatic vibrator of the present invention, the operator can quickly set the vibration time and interval of all vibrators in front of the control cabinet, without having to run back and forth between the various vibrators as before, greatly improving construction efficiency.

[0045] The control process of the control cabinet is as follows:

[0046] Step 1: Manually close the circuit breaker switch in the control cabinet. The circuit breaker switch is turned on, allowing the mains power to supply power to each module in the control cabinet and external devices (such as solenoid valve 5 and valve island), providing power source for the entire equipment.

[0047] Step 2: After the control cabinet is powered on, it will automatically initialize the test to check whether the modules it controls are normal. If an error occurs, it will be displayed on the touch screen. After the test is completed and confirmed to be normal, the touch screen will display normally.

[0048] Step 3: You need to set the parameters on the touch screen of the control cabinet. The parameters include the single control time and vibration interval of the vibrator, combination setting, vibration intensity control (achieved by the length of the inflation and deflation time), etc. After the settings are completed, you can start the control button to vibrate;

[0049] Step 4: During the vibrating process, the touch screen will display information such as the number of vibrations completed and the remaining number of vibrations. The control cabinet also has an emergency stop function and the function of remotely issuing vibration commands.

[0050] Step 5: After the vibration process is completed, the worker moves the vibrator to the next position and repeats steps 1-4 to finally complete the vibration work of the second lining trolley.

[0051] In one embodiment, a local pushbutton box is assigned for every four sets of attached vibrators, allowing for individual control of each set and improving control flexibility and convenience. When adjustments are needed for a particular set of vibrators, operators can do so directly from the corresponding local pushbutton box, eliminating the need for complex settings in the main control cabinet. For example, if a particular set of vibrators is experiencing unsatisfactory vibration performance, operators can quickly adjust the vibration time or interval for that set from a nearby local pushbutton box, promptly resolving the issue and ensuring construction quality.

[0052] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
