Description

Technical Field

[0001] This utility model relates to the field of concrete compaction technology, and in particular to a concrete compaction device. Background Technology

[0002] After concrete is poured, it needs to be compacted using a vibrator to remove air from the concrete. Currently, when using a vibrator, a person holds the vibrator and inserts it into the concrete for compaction. However, existing vibrators have poor vibration damping performance for the hand. The vibration of the vibrator itself is transmitted to the hand, and prolonged vibration can cause vascular spasms and circulatory disorders in the hand. The fingertips may become pale and numb due to ischemia, which is harmful to human health. Therefore, in view of the above situation, there is an urgent need to develop a concrete compaction device that can greatly reduce the vibration transmitted to the hand through multiple vibration damping and isolation methods, thereby improving the protection of the human body, overcoming the shortcomings of current practical applications, and meeting current needs. Utility Model Content

[0003] The purpose of this invention is to provide a concrete compaction device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A concrete compaction device includes an outer shell, a top cover, a vibration mechanism, a vibration damping mechanism, an operating handle, and a rubber vibration isolation sleeve. The top cover is detachably fixed to the top of the outer shell by screws. A vibration mechanism is connected between the outer shell and the top cover, and the vibration mechanism is used to drive the outer shell to vibrate. A vibration damping mechanism is installed on both the left and right sides of the outer shell. The lower end of the operating handle is fixed to the two vibration damping mechanisms respectively. A rubber vibration isolation sleeve is fixed to the outside of the operating handle. The vibration damping mechanism includes: a sliding rod, a sliding sleeve, a spring, and a damper. The sliding rod is fixed to the side of the outer shell, and a sliding sleeve is slidably installed on the sliding rod. A spring is installed on both the upper and lower sides of the sliding sleeve. The damper is fixed to the side of the outer shell, and the piston rod of the damper is fixed to the sliding sleeve. The lower end of the operating handle is welded to the sliding sleeve. A cavity is provided inside the operating handle, and the cavity stores damping fluid.

[0006] Preferably, the vibration mechanism includes a drive motor, a transmission shaft, and an eccentric block. The drive motor is fixed on the top cover, the output shaft of the drive motor is fixed to the transmission shaft via a coupling, the transmission shaft is rotatably connected to the outer casing via a bearing, and an eccentric block is fixed on the transmission shaft.

[0007] Preferably, a switch button is installed on the top cover, and the drive motor is electrically connected to the switch button.

[0008] Preferably, the outer casing is made of stainless steel.

[0009] Preferably, the operating handle is provided with a filling port that communicates with the cavity, and a plug is detachably connected to the filling port by means of threads.

[0010] The beneficial effects of this utility model are as follows: When using this concrete compaction equipment, the operator holds the rubber vibration isolation sleeve on the outside of the operating handle, inserts the outer shell into the concrete, and starts the drive motor to rotate the transmission shaft and eccentric block. The eccentric block causes an imbalance in weight, resulting in vibration during rotation. This vibration is transmitted to the outer shell, which then compacts the concrete. Additionally, the outer shell transmits the vibration to the vibration damping mechanism. The spring deforms to buffer the vibration, and the sliding sleeve moves up and down, transmitting the vibration force to the piston rod of the damper. The damper absorbs the vibration, reducing its transmission to the operating handle, which then vibrates the damping fluid inside the cavity. The damping fluid converts the kinetic energy of the vibration into heat energy through internal friction and viscous resistance, thus suppressing the transmission and amplification of vibration. Finally, the rubber vibration isolation sleeve further absorbs and isolates the vibration, significantly reducing the vibration transmitted to the operator's hand and minimizing its impact on the human body. In summary, this utility model significantly reduces the transmission of vibration to the operator's hand through multiple vibration reduction and isolation mechanisms, improving protection for the operator.

The top cover 2 is detachably fixed to the top of the outer shell 1 by screws. The vibration mechanism 3 is connected between the outer shell 1 and the top cover 2. The vibration mechanism 3 is used to drive the outer shell 1 to vibrate. A vibration damping mechanism 4 is installed on each of the left and right sides of the outer shell 1. The lower end of the operating handle 5 is fixed to two vibration damping mechanisms 4 respectively. A rubber vibration isolation sleeve 6 is fixed to the outside of the operating handle 5. The vibration damping mechanism 4 includes: a sliding rod 401, a sliding sleeve 402, a spring 403, and a damper 404. 401 is fixed to the side of the outer shell 1. A sliding sleeve 402 is slidably mounted on the sliding rod 401. A spring 403 is installed on both the upper and lower sides of the sliding sleeve 402. The damper 404 is fixed to the side of the outer shell 1. The piston rod of the damper 404 is fixed to the sliding sleeve 402. The lower end of the operating handle 5 is welded to the sliding sleeve 402. A cavity 503 is provided inside the operating handle 5. The cavity 503 stores damping fluid. A filling port 501 connected to the cavity 503 is provided on the operating handle 5. A plug 502 is detachably connected to the filling port 501 by a thread. Damping fluid can be added into the cavity 503 by removing the plug 502.

[0021] The vibration mechanism 3 includes a drive motor 301, a transmission shaft 302, and an eccentric block 303. The drive motor 301 is fixed on the top cover 2. The output shaft of the drive motor 301 is fixed to the transmission shaft 302 through a coupling. The transmission shaft 302 is rotatably connected to the outer shell 1 through a bearing. An eccentric block 303 is fixed on the transmission shaft 302. In use, the drive motor 301 drives the transmission shaft 302 and the eccentric block 303 to rotate. The action of the eccentric block 303 causes an imbalance in weight, which generates vibration during rotation. The vibration is transmitted to the outer shell 1.

[0022] A switch button 7 is installed on the top cover 2. The drive motor 301 is electrically connected to the switch button 7 for control. A connector wire 8 is connected to the drive motor 301. A plug is provided on the connector wire 8. The connector wire 8 is used to plug into an external circuit socket.

[0023] The outer shell 1 is made of stainless steel, which gives it good corrosion resistance.

[0024] Working Principle: When using this concrete compaction equipment, the operator holds the rubber vibration isolation sleeve 6 on the outside of the operating handle 5, inserts the outer shell 1 into the concrete, and starts the drive motor 301 to rotate the transmission shaft 302 and eccentric block 303. The eccentric block 303 causes weight imbalance, resulting in vibration during rotation. This vibration is transmitted to the outer shell 1, which compacts the concrete. Additionally, the outer shell 1 transmits the vibration to the vibration damping mechanism 4. The spring 403 deforms to buffer the vibration, and the sliding sleeve 402 moves up and down, transmitting the vibration force to the piston rod of the damper 404. The damper 404 absorbs the vibration, reducing its transmission to the operating handle 5, which in turn vibrates the damping fluid inside the cavity 503. The damping fluid converts the kinetic energy of the vibration into heat energy through internal friction and viscous resistance, thus suppressing the transmission and amplification of vibration. Finally, the rubber vibration isolation sleeve 6 further absorbs and isolates the vibration, significantly reducing the vibration transmitted to the operator's hand and minimizing its impact on the human body.
