Description

Technical Field

[0001] This invention relates to the field of vibration compaction tables, and in particular to a vibration compaction table for noise-reducing concrete test blocks. Background Technology

[0002] In fields such as building materials testing and civil engineering experiments, the preparation of concrete test blocks requires the compaction of the concrete mortar within the mold using a vibratory compaction table. This process removes air bubbles, ensures the density of the test blocks, and provides reliable samples for subsequent strength testing. The working principle of a traditional concrete test block vibratory compaction table is that a motor drives the vibratory compaction components to cause the table surface to vibrate at high frequency, thus compacting the concrete under the action of vibration. According to the public announcement (CN211993450U), a concrete vibration compaction table is disclosed. This technology discloses a technical solution that includes "a drive motor, a coupling fixedly installed on the output shaft of the drive motor, a transmission screw fixedly installed at the end of the coupling away from the drive motor, a cleaning slider threadedly connected to the surface of the transmission screw, a cleaning brush fixedly connected to the end of the cleaning slider away from the transmission screw, a first hydraulic telescopic rod fixedly connected to the end of the vibration compaction support away from the drive motor, and a conversion bracket fixedly connected to the end of the first hydraulic telescopic rod away from the vibration compaction support, etc. This solution has the technical effect of converting the rotational motion of the transmission screw into the linear motion of the cleaning slider through threaded transmission, causing the cleaning slider to slide along the limiting groove of the vibration compaction support, and driving the cleaning brush to move through the cleaning slider, thereby enabling the cleaning brush to clean the surface of the vibration compaction table, facilitating timely and rapid cleaning of the vibration compaction table, and avoiding affecting subsequent work." In the aforementioned comparative documents, although the rotational motion of the transmission screw is converted into the linear motion of the cleaning slider through threaded transmission, allowing the cleaning slider to slide along the limiting groove of the vibratory support, and the cleaning brush to move via the cleaning slider, thus cleaning the surface of the vibratory table, facilitating timely and rapid cleaning of the vibratory table and avoiding impact on subsequent work, the vibratory table presents a significant noise pollution problem during use. When the vibratory table is working, the high-frequency vibration generated by the vibratory components is transmitted to the base through the table and support, and then diffused to the ground and surrounding structures through the rigid connection between the base and the ground, forming solid-borne sound. At the same time, the friction and collision of equipment parts caused by vibration are directly radiated into airborne sound. Long-term exposure to such a high-noise environment can cause multiple health hazards to operators: high-frequency noise can easily lead to hearing damage, while low-frequency resonance noise may cause dizziness, mental tension, and distraction, increasing the risk of operational errors. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a noise-reducing concrete test block vibration table to solve the problem of excessive noise during use in the aforementioned technical solutions. The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A noise-reducing concrete test block vibration table includes a support platform, a shell movably connected to the top of the support platform, a support plate provided on the top of the support platform, a vibration component provided on the support plate, and a noise-reducing component provided on the top of the support plate. The noise-reducing component includes a spring, a connecting ring, a placement platform, a limiting tube, and a limiting rod. Multiple springs are provided, multiple connecting rings are provided, and two adjacent springs are connected by a connecting ring. The top of the support plate is fixedly connected to the bottom of the limiting tube, the inner wall of the limiting tube is slidably connected to the outer wall of the limiting rod, and the top of the limiting rod is fixedly connected to the bottom of the placement platform.

[0004] The vibration compaction assembly includes a motor, a rotating rod, a half gear, and a rack. The protrusion on the top of the support plate is detachably connected to the outer wall of the motor. The rotating shaft of the motor is fixedly connected to one end of the rotating rod. The outer wall of the rotating rod is fixedly connected to the inner wall of the half gear. The bottom of the placement platform is fixedly connected to the top of the rack. The rack is connected to the half gear by meshing teeth. By setting the vibration compaction assembly, the concrete on the placement platform is compacted.

[0005] The bottom of the limiting tube is fixedly connected to a first soft pad, the bottom of the limiting rod is fixedly connected to a second soft pad, the outer wall of the limiting rod is fixedly connected to a first soft ring, and the top of the limiting tube is fixedly connected to a second soft ring. By setting the first soft pad, the second soft pad, the first soft ring, and the second soft ring, the sound generated when the platform moves up and down is reduced, thereby preventing the platform from making a lot of noise when moving up and down and affecting the surrounding environment.

[0006] The bottom of the support platform is fixedly connected to a support base, and the bottom of the support base is equipped with a suction cup. By setting up the support base and the suction cup, the vibration platform is stabilized and the sound transmitted from the vibration platform to the sound source placed on the table is reduced, thereby avoiding loud noise that may affect the surrounding environment.

[0007] A fixing plate is fixedly connected to the top of the support plate, and a bearing is fixedly connected to the fixing plate. The inner ring of the bearing is fixedly connected to the end of the rotating rod away from the motor. By setting the fixing plate and the bearing, the rotating rod is stabilized, and the shaking of the rotating rod during rotation is prevented, thereby avoiding affecting the up and down movement of the half gear transmission rack.

[0008] The top of the support platform is fixedly connected with sound insulation cotton. The outer wall of the sound insulation cotton is attached to the inner wall of the outer shell. By setting the sound insulation cotton, the sound generated by vibration is isolated, thereby preventing the sound from being transmitted to the outside.

[0009] A support pad is fixedly connected to the bottom of the support plate. The bottom of the support pad fits into the groove set on the top of the support platform. By setting the support pad, the energy transmitted from the placement platform to the support plate is reduced, thereby avoiding loud noise caused by the vibration of the placement platform.

[0010] The beneficial effects of this invention are: By setting up noise reduction components, the sound generated by the vibration table can be reduced. When the vibration table is working, the vibration is transmitted to the ground through the table surface and base, thus forming noise. At this time, the noise reduction components can effectively reduce the transmission of vibration, reduce noise at the source, and at the same time, the noise reduction can prevent operators from being exposed to a high-noise environment for a long time, thereby improving the safety of the working environment and protecting the health of personnel.

[0011] By setting up a vibration compaction component, the concrete on the placement platform can be compacted. The vibration compaction component can move the placement platform up and down simultaneously from multiple points, thereby improving the uniformity of compaction and ensuring that the density of the test blocks is consistent. At the same time, multi-point drive can make the vibration force transmission more uniform, thereby improving compaction efficiency and shortening the operation time. Attached Figure Description
