[0026] In order to solve the problem in the prior art that the method of compacting concrete by beating increases the labor intensity of workers and affects work efficiency, the present application provides a vibrator for concrete slabs.

[0027] like Figures 1 to 5 As shown, the vibrator for concrete slabs includes a main body 10, a vibrating part 20 and a connecting component 30. The main body 10 includes a main body and a wheel 11 arranged on the main body, and the main body includes a gas delivery pipeline 12. The vibrating part 20 is detachably arranged on the main body, and the vibrating part 20 includes a mounting plate 21 and a pneumatic vibrator 22 arranged on the mounting plate 21. The gas delivery pipeline 12 is connected to the air inlet of the pneumatic vibrator 22 through the connecting component 30 to deliver gas into the air inlet. There is one pneumatic vibrator 22; or there are multiple pneumatic vibrators 22, and the multiple pneumatic vibrators 22 are arranged at intervals along at least one direction of the length direction, width direction and height direction of the mounting plate 21.

[0028] By applying the technical solution of this embodiment, during the construction of underground concrete slabs, when it is necessary to tap and compact the concrete, compressed gas is delivered to the gas delivery pipeline 12 so that the compressed gas enters the pneumatic vibrator 22. At this time, the pneumatic vibrator 22 itself vibrates and drives the mounting plate 21 to vibrate synchronously, so as to replace manual tapping and compacting of the concrete, thereby solving the problem that the tapping and compacting of concrete in the prior art increases the labor intensity of the workers and affects the work efficiency, and reduces the labor intensity of the workers. At the same time, when the workers use the vibrator, they can move or transport the vibration part 20 by pushing the main body 10, so that the workers can adjust the vibration position of the vibration part 20.

[0029] In this embodiment, there are two pneumatic vibrators 22, and the two pneumatic vibrators 22 are arranged at intervals along the length direction of the mounting plate 21. In this way, the above arrangement makes the structure of the vibration part 20 simpler, easier to process and realize, and reduces the processing cost and difficulty of the vibrator.

[0030] It should be noted that the number of the pneumatic vibrators 22 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the number of the pneumatic vibrators 22 is three, four, five, six, or more.

[0031] It should be noted that the arrangement of the pneumatic vibrators 22 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, a plurality of pneumatic vibrators 22 are arranged at intervals along the width direction of the mounting plate 21 .

[0032] Optionally, a plurality of pneumatic vibrators 22 are arranged at intervals along the height direction of the mounting plate 21 .

[0033] like Figure 1 and Figure 5 As shown, there are multiple pneumatic vibrators 22, and the gas delivery pipeline 12 includes a main pipe 121 and multiple branch pipes 122. The main pipe 121 is connected to the gas supply device, and each branch pipe 122 is connected to the main pipe 121. Among them, the multiple branch pipes 122 are arranged in a one-to-one correspondence with the multiple pneumatic vibrators 22, and each branch pipe 122 delivers gas to the corresponding pneumatic vibrator 22. In this way, through the above-mentioned multi-point gas supply method, the uniform vibration of the pneumatic vibrator 22 can be ensured, and the compaction quality and efficiency of the concrete slab can be improved.

[0034] Specifically, there are two branch pipes 122, and the two branch pipes 122 are arranged in one-to-one correspondence with the two pneumatic vibrators 22. After starting the two pneumatic vibrators 22, there are two places on the mounting plate 21 for vibration, which avoids the problem of uneven vibration caused by single-point air supply, significantly improves the compaction effect of the concrete slab, reduces the need for subsequent repair work, thereby reducing the project cost and accelerating the project progress.

[0035] Optionally, the main body 10 further includes a first control valve 13, which is arranged on the main pipe 121 to control the on / off state of the main pipe 121 and / or the gas flow or flow rate in the main pipe 121; and / or, the main body 10 further includes a plurality of second control valves, which are arranged one-to-one with the plurality of branch pipes 122, and each second control valve is arranged on the corresponding branch pipe 122 to control the on / off state of the branch pipe 122 and / or the gas flow or flow rate in the branch pipe 122. In this way, the above-mentioned precise flow control enables the vibrator to adapt to concrete slabs of different hardness and thickness, improve the compaction effect, and also effectively save energy and reduce noise, and is suitable for engineering sites with high requirements for environmental protection and energy saving.

[0036] In this embodiment, the gas flow and flow rate are accurately controlled by the first control valve 13, which can not only adapt to concrete slabs of various hardness and thickness, but also achieve efficient use of energy while ensuring the compaction effect, reduce noise and vibration during equipment operation, and provide a more comfortable working environment for on-site workers, which meets the high standards of modern engineering for environmental protection and energy saving.

[0037] like Figure 1 As shown, the connecting component 30 includes a plurality of first joints 31 and a plurality of hoses 32. Among them, the plurality of first joints 31 are arranged on the mounting plate 21, and the plurality of first joints 31 are arranged one-to-one with the plurality of pneumatic vibrators 22, and each first joint 31 is connected to the air inlet of the corresponding pneumatic vibrator 22. The plurality of hoses 32 are arranged one-to-one with the plurality of branch pipes 122, and each branch pipe 122 transports gas to the corresponding first joint 31 through the corresponding hose 32. In this way, the above arrangement makes the gas transportation more stable, reduces the risk of gas leakage, and improves the operational reliability and safety of the vibrator. At the same time, the use of the hose 32 not only increases the stability of gas transportation, but also improves the flexibility of the equipment when operating in complex terrain, reduces the safety hazards caused by gas leakage, and ensures the stability and efficiency of long-term continuous operation.

[0038] In this embodiment, there are two first joints 31, and the two first joints 31 are arranged in a one-to-one correspondence with the two pneumatic vibrators 22. There are two hoses 32, and the two hoses 32 are arranged in a one-to-one correspondence with the two first joints 31, thereby ensuring that the compressed gas entering each branch pipe 122 can enter the air inlet of the pneumatic vibrator 22 through a hose 32 and a first joint 31 in sequence, so as to achieve smooth transmission of the compressed gas.

[0039] like Figure 1 and Figure 2As shown, the connecting component 30 also includes a plurality of second joints 33, and the plurality of second joints 33 are arranged in one-to-one correspondence with the plurality of branch pipes 122, and each second joint 33 is arranged on the corresponding branch pipe 122 and is connected with the branch pipe 122; the plurality of second joints 33 are arranged in one-to-one correspondence with the plurality of hoses 32. Among them, each second joint 33 conveys gas to the corresponding first joint 31 through the corresponding hose 32. In this way, by setting the second joint 33, the stability and safety of gas transportation are further enhanced, which is suitable for engineering sites that need to operate under complex terrain and severe weather conditions. At the same time, the addition of the second joint 33 enhances the redundancy of the gas transportation system, and even in severe weather conditions, such as strong winds and heavy rains, the stable transportation of gas can be guaranteed, preventing the pneumatic vibrator 22 from affecting the operating effect due to insufficient gas supply.

[0040] In this embodiment, there are two second connectors 33, and the two second connectors 33 are arranged in one-to-one correspondence with the two hoses 32. The compressed gas entering each branch pipe 122 passes through the second connector 33, the hose 32, and the first connector 31 in sequence and enters the air inlet of the pneumatic vibrator 22 to achieve smooth transmission of the compressed gas.

[0041] like Figure 3 and Figure 5 As shown, a preset space 23 is formed between two adjacent pneumatic vibrators 22, and the plurality of branch pipes 122 include a first branch pipe 1221 and a second branch pipe 1222, wherein the first branch pipe 1221 extends along a first direction. The second branch pipe 1222 extends along a second direction, and the first direction is opposite to the second direction. Among them, the first branch pipe 1221 and the second branch pipe 1222 are located in the preset space 23. In this way, the above arrangement makes the vibration of the pneumatic vibrator 22 more uniform, thereby improving the compaction effect of the concrete slab. At the same time, the above arrangement of the preset space 23 not only ensures the uniform vibration of the pneumatic vibrator 22, but also facilitates the operator to observe and maintain the equipment when it is running, thereby improving the maintenance efficiency and operation safety of the equipment.

[0042] like Figure 2 As shown, the mounting plate 21 has a through hole, and the vibrator also includes a first connecting structure 40, and the first connecting structure 40 includes a connecting body and a fastener. Among them, the connecting body has a accommodating cavity, an installation opening and a through hole, and the installation opening and the through hole are both connected to the accommodating cavity, and at least part of the mounting plate 21, the first branch pipe 1221 and / or the second branch pipe 1222 are all installed in the accommodating cavity through the installation opening. The fastener is inserted into the through hole to cover at least part of the installation opening. In this way, the above-mentioned arrangement makes the assembly and disassembly of the vibrator more convenient, improves the maintenance efficiency of the equipment, and reduces the maintenance time and cost. At the same time, the above-mentioned arrangement makes the disassembly and assembly of the main body 10 and the vibration part 20 easier and simpler, and reduces the difficulty of disassembly and maintenance of the two.

[0043] In this embodiment, the connection body includes two first connection parts and a second connection part arranged opposite to each other. The two first connection parts are connected by the second connection part to form a receiving cavity and a mounting opening around the second connection part; and a through hole is provided on at least one of the first connection parts. In this way, the above arrangement increases the contact area between the main body 10 and the vibration part 20, thereby improving the assembly stability of the two.

[0044] like Figure 1 , Figure 2 as well as Figure 5 As shown, the main body 10 also includes an operating handle 14. The operating handle 14 is arranged on the first end of the main pipe 121, and the plurality of branch pipes 122 are arranged on the second end of the main pipe 121. And / or, the main body 10 also includes a second connecting structure 15, and the second connecting structure 15 is arranged on the middle part of the main pipe 121, and the wheel 11 is connected to the main pipe 121 through the second connecting structure. In this way, the above-mentioned setting of the operating handle 14 facilitates the staff to operate the main body 10, and improves the user experience. At the same time, the above-mentioned setting of the second connecting structure 15 makes it easier and simpler to disassemble and assemble the wheel 11 and the main pipe 121, and reduces the difficulty of disassembling and assembling the two.

[0045] In this embodiment, the wheel shaft 111 is rotatably disposed on the second connecting structure 15 .

[0046] Optionally, anti-skid patterns are provided on the operating handle 14. In this way, the anti-skid design of the operating handle 14 makes the operator more stable during use, improves the operability and safety of the equipment, and is suitable for engineering sites that need to operate in slippery or muddy environments.

[0047] Optionally, the extension direction of the main pipe 121 is set at an angle with the mounting plate 21, and / or there is one first connection structure 40; or there are multiple first connection structures 40, and the multiple first connection structures 40 are arranged at intervals along the length direction of the mounting plate 21. In this way, the angle design between the main pipe 121 and the mounting plate 21 and the arrangement of multiple first connection structures 40 improve the stability of the vibrator under high wind speed or unstable terrain conditions, prevent the device from being offset or overturned due to external factors, and improve the safety and efficiency of the operation.

[0048] Optionally, the first connection structure 40 is a shackle, which is used to connect the mounting plate 21 and the main body 10 to ensure the overall stability and operability of the vibrator. In this way, the use of the shackle not only improves the connection strength of the vibrator, but also simplifies the disassembly and assembly process of the vibrator.

[0049] Optionally, the operating handle 14 is made of metal. In this way, the above arrangement not only improves the durability of the vibrator, but also makes the operation more comfortable, improves the operator's operating efficiency, and is suitable for engineering sites that require long-term continuous operation.

[0050] Optionally, the operating handle 14 is connected to the main pipe 121 by an articulated manner. In this way, the above arrangement allows the operating handle 14 to be adjusted in angle according to the needs of the operator, thereby improving the adaptability of the equipment and the comfort of the operator, and improving the operating efficiency and safety.

[0051] Optionally, the air pressure of the pneumatic vibrator 22 is adjustable so that the vibrator can be precisely adjusted according to the hardness and thickness of the concrete slab, thereby improving the compaction effect and the applicability of the equipment.

[0052] Optionally, the first joint 31 and the second joint 33 have a dustproof and waterproof design, which not only prolongs the service life of the vibrator, but also reduces maintenance costs and improves the economic benefits of the equipment. It is suitable for use in engineering sites that need to be dusty or rainy.

[0053] Optionally, the first control valve and / or the second control valve is a stop valve. In this way, the manually controlled stop valve is not only simple and intuitive to operate, but also improves the reliability of the vibrator.

[0054] Optionally, the bottom of the mounting plate 21 is provided with a wear-resistant coating, which not only improves the wear resistance and service life of the vibration part 20, but also reduces the maintenance frequency, reduces the maintenance cost, and improves the safety and efficiency of the operation.

[0055] Specifically, the vibrator works as follows;

[0056] When using the vibrator for operation, the first connecting structure 40 is inserted into the two through holes reserved on the mounting plate 21, so that the main body 10 is fixedly connected to the vibration part 20. Use two rubber hoses 32 to connect the first joint 31 and the second joint 33 accordingly. Take air from the underground main pipe 121, and turn on and off the pneumatic vibrator 22 through the first control valve 13. After the first control valve 13 is opened, the pneumatic vibrator 22 starts to vibrate to drive the mounting plate 21 to vibrate synchronously, and the operator realizes the pushing and turning of the vibrator by operating the handle 14 and the wheel 11.

[0057] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

There is one pneumatic vibrator; or, there are multiple pneumatic vibrators, and the multiple pneumatic vibrators are arranged at intervals along at least one direction of the length direction, the width direction and the height direction of the mounting plate. In this way, during the construction of the underground concrete slab, when it is necessary to tap and compact the concrete, compressed gas is delivered to the gas delivery pipeline so that the compressed gas enters the pneumatic vibrator, and at this time, the pneumatic vibrator itself vibrates and drives the mounting plate to vibrate synchronously, so as to replace manual tapping and compacting of the concrete, thereby solving the problem that the method of tapping and compacting concrete in the prior art increases the labor intensity of the staff and affects the work efficiency, and reduces the labor intensity of the staff.
