Description

Technical Field

[0001] The utility model relates to the technical field of concrete vibration, in particular to a concrete vibration noise reduction device. Background Art

[0002] Concrete vibration should be carried out in layers in an orderly manner according to the length of the vibrating rod and the effective radius of vibration. The moving distance of the vibrating rod can generally be about 40cm (small-section structures and nodes with dense steel bars should be vibrated to a certain degree). The depth of the vibrating rod inserted into the lower layer of vibrated concrete should be no less than 5cm. The vibration time should be strictly controlled, generally about 20 seconds, to prevent leakage or over-vibration. The steel bar protective layer and reserved holes, embedded parts and exposed steel bar positions should be checked at any time to ensure that the embedded parts and the concrete at the bottom of the prestressed steel bar bearing plate are dense and the exposed surface layer is flat. The construction joint meets the requirements. An attached vibrator can be added to the closed formwork to assist in vibration.

[0003] The existing utility model patent with announcement number CN 216156303 U and publication date 2022.04.01 discloses a concrete vibrating device for highway engineering construction with noise reduction function, including a vibration motor and a vibration rod, the transmission output end of the vibration motor is transmission-connected to the vibration rod, a lower shell and an upper shell are installed outside the vibration motor, the upper shell is detachably connected to the lower shell by bolts, sound insulation cotton is bonded to the inner walls of the lower shell and the upper shell, a rubber seat is symmetrically installed at the bottom end of the lower shell, the vibration motor is installed on the upper surface of the rubber seat, the upper surface of the vibration motor is fixedly connected to the card plate, the top end of the upper shell is fixedly connected to the support plate, and the lower surface of the support plate is fixedly connected to the pressure plate through a spring seat;

[0004] The utility model adds a lower shell and an upper shell to the outside of the vibration motor. The lower shell and the upper shell have good sound insulation performance and are used together with sound insulation cotton to reduce the noise generated by the vibration motor during operation, reduce the harm to construction workers, and improve the comfort of the working environment.

[0005] However, this patent also reveals a shortcoming: when installing the vibration motor, the vibration motor is directly placed on the rubber seat without being fixed. As a result, the vibration motor moves inside the shell due to its own vibration during operation, which increases the vibration amplitude of the entire shell. Although a spring seat is provided on the upper shell to clamp and fix the longitudinal position of the vibration motor, most of the movement of the vibration motor during operation comes from lateral movement, which can cause the vibration motor to slide off the rubber seat and directly contact the lower shell, resulting in increased noise. Therefore, this patent lacks a fixing mechanism for the lateral position of the vibration motor.

[0006] Therefore, there is an urgent need for a concrete vibration noise reduction device, which is used to effectively fix the lateral position of the vibration motor, reduce the lateral movement of the vibration motor itself during operation, and reduce the noise during vibration. Utility Model Content

[0007] In view of the above technical problems, the utility model provides a concrete vibration noise reduction device, which is used to solve the problem that the existing vibration device lacks a fixing mechanism for the lateral position of the vibration motor, thereby making the vibration motor prone to lateral movement and aggravating the problem of increased noise.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] A concrete vibration noise reduction device comprises a vibration motor, a vibration guide tube, a vibration rod, and a noise reduction box, wherein the noise reduction box comprises a box body and a box cover, a sound insulation pad is arranged at the bottom of the box body, a slide rail is arranged in parallel on the sound insulation pad, two slide seats are arranged on the slide rail for parallel sliding, connecting pieces are arranged at both ends of the slide seat, the slide seat is detachably and symmetrically provided with a right-angle rigid piece through the connecting piece, a first damping pad is arranged on two right-angle sides of the right-angle rigid piece, a support plate is arranged horizontally between the two right-angle sides of the right-angle rigid piece, a second damping pad is arranged on the support plate, and the vibration motor is placed on the second damping pad;

[0010] A driving threaded hole is concentrically opened in the middle of the two slide seats, and a lead screw is matched in the driving threaded hole. The two slide seats move toward each other under the action of the lead screw.

[0011] Furthermore, a driving disk is provided at one end of the lead screw, and the driving disk is located outside the box body, and a bearing seat is provided at the other end of the lead screw.

[0012] Furthermore, positioning holes are provided at four corners of the box body, positioning posts are provided at positions of the box cover corresponding to the positioning holes, connecting holes are provided on the positioning posts, and connecting bolts are provided in the connecting holes.

[0013] Furthermore, four universal wheels are arranged in a rectangular shape at the bottom of the box.

[0014] Furthermore, a plurality of rubber columns are arranged in a rectangular shape on one side of the box cover located at the vibration motor, and one end of the rubber column abuts against one side of the vibration motor.

[0015] Furthermore, the box body and the box cover are covered with a vibration reduction layer and a sound insulation layer in sequence from the outside to the inside, the vibration reduction layer is made of damping rubber, and the sound insulation layer is made of sound insulation cotton.

[0016] Furthermore, a fan is provided on the box cover, and the fan is used to draw air out of the noise reduction box to cool it down.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] (1) The vibration motor is placed on a support plate with a second damping pad, and the two slides are driven by a lead screw to move toward each other. The four corners of the vibration motor are clamped and fixed by four rectangularly arranged right-angle rigid parts, thereby avoiding lateral movement of the vibration motor during vibration, avoiding direct contact between the vibration motor and the bottom of the box, and preventing the increase of noise. At the same time, the first damping pad effectively absorbs the vibration generated by the vibration motor and transmits it outward. At the same time, the box and the box cover covered with a vibration reduction layer and a sound insulation layer effectively achieve the purpose of noise reduction.

[0019] (2) The box body and the box cover can be connected together by using positioning holes, positioning columns and connecting bolts, thereby blocking the direct contact between the vibration motor and the outside world and reducing the spread of noise.

[0020] (3) The use of universal wheels facilitates the movement of the entire noise reduction box, making it more labor-saving and flexible when pulling the noise reduction box through the vibration guide tube.

[0021] (4) Use rubber columns to limit the longitudinal position of the vibration motor to prevent the vibration motor from jumping along the longitudinal direction and increasing noise.

[0022] (5) The fan can be used to promptly remove the heat generated by the vibration motor, thereby reducing the temperature inside the entire noise reduction box and preventing the vibration motor from being damaged by excessive temperature. BRIEF DESCRIPTION OF THE DRAWINGS
