Description

Technical Field

[0001] This utility model relates to the field of concrete vibration equipment technology, and in particular to a high-efficiency concrete vibration device. Background Technology

[0002] Concrete vibrators are frequently used in the construction of municipal roads and bridges. A concrete vibrator is a device used during concrete construction to compact the poured concrete. It generates high-frequency vibrations, causing the particles inside the concrete to move and rearrange, expelling air and making the concrete dense and uniform, improving its strength and durability, while also enhancing the smoothness and evenness of the concrete surface.

[0003] Most existing concrete vibrating devices only have the function of vibrating in the horizontal direction and cannot vibrate in the vertical direction. This means that the vibrating rod can only perform a single form of vibration on the concrete in the horizontal direction, and cannot perform multi-directional composite vibration on the concrete, which in turn affects the compaction effect of the vibrating device on the concrete. Utility Model Content

[0004] In view of this, the present invention provides a high-efficiency concrete vibration device to solve the problem that the vibrator can only vibrate concrete in a single form in the horizontal direction and cannot perform multi-directional composite vibration on concrete.

[0005] The technical solution proposed by this utility model is: a high-efficiency concrete vibration device, specifically including a hollow vibration rod, wherein two bearings are embedded in the upper and lower ends of the hollow vibration rod.

[0006] A vibrating shaft is rotatably mounted through the inner rings of the two bearings. A positioning ring is welded to the center of the lower half of the hollow tamping rod. The vibrating shaft rotates through the positioning ring and slides in a manner that is reset by spring push. An L-shaped drive rod is welded to the vibrating shaft, and a guide wheel is rotatably mounted at the bottom end of each L-shaped drive rod. Two positioning rings are fixedly connected at an upper and lower interval on the inner bottom side of the hollow tamping rod. A triangular drive block is welded to the top of the upper positioning ring. A guide wheel rolls and abuts against the top ring surface of the positioning ring. When the guide wheel is driven to roll along the top ring surface, it abuts against the inclined surface of the triangular drive block in sequence.

[0007] Furthermore, the vibration shaft is symmetrically fitted with two damping rings in the part between the positioning ring and the lower bearing. The spring that pushes the vibration shaft back to its original position is fitted on this part and its head and tail are fixedly connected to the two damping rings respectively. The part is also welded with an installation ring.

[0008] The tail end of an L-shaped drive rod is welded and fixed to the outer circumference of the mounting ring.

[0009] Furthermore, a ring of steel balls is embedded on the opposite side of each of the two damage reduction rings, and the two rings of steel balls roll and abut against the positioning ring and the mounting ring respectively.

[0010] Furthermore, a positioning ring is fixedly connected to the inner side of the top part of the vibration shaft, and the bottom side of the outer ring of the upper bearing abuts against the positioning ring.

[0011] The lower bearing is positioned between the two locating rings on the lower side.

[0012] Furthermore, a polarizing strip is provided protruding from the outer periphery of the vibration shaft.

[0013] Furthermore, it also includes a drive motor, with a soft tube connecting the drive motor and the vibration shaft. A flexible shaft is threaded through the soft tube, and the two ends of the flexible shaft are connected to the rotating shaft of the drive motor and the vibration shaft, respectively.

[0014] The high-efficiency concrete vibration device provided by this utility model has the following beneficial effects:

[0015] 1. By using the inclined guiding effect of a triangular drive block and the counter-pushing effect of the spring, the vibrating shaft can drive its body to vibrate up and down at high frequency when rotating at high speed. This, combined with the horizontal high-frequency vibration of the vibrating shaft, can perform compound dual vibration of concrete in both horizontal and vertical directions, which helps to improve the compaction effect of the vibrating device on concrete and the practicality of the vibrating device.

[0016] Second, through the inclined plane guiding effect of a ring of triangular drive blocks, the up and down vibration operation of the vibrating shaft can be driven by its own rotational driving force. This eliminates the need to configure an additional drive unit for the up and down vibration operation of the vibrating shaft, which helps to reduce the cost and power consumption of the vibrating device.

[0017] Third, the spring that pushes the vibration shaft back to its original position has two wear-reducing rings at both ends that indirectly abut against the positioning ring and the mounting ring. These two wear-reducing rings separate the two ends of the spring from the positioning ring and the mounting ring, preventing the two ends of the spring from directly abutting against the positioning ring and the mounting ring and rotating relative to the positioning ring and the mounting ring under the drive of the vibration shaft, thus avoiding excessive wear on the two ends of the spring and helping to extend the service life of the spring. The two coils of steel balls, through their rolling and guiding effect, can reduce the relative wear between the two wear-reducing rings and the positioning ring and the mounting ring, extending the service life of the above components.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Please refer to Figures 1 to 5 Example 1:

[0035] This embodiment proposes a high-efficiency concrete vibration device, including a hollow vibrating rod 3, with two bearings 6 embedded at the upper and lower ends inside the hollow vibrating rod 3.

[0036] Vibration shafts 5 are rotatably mounted through the inner rings of two bearings 6. A positioning ring 302 is welded to the center of the lower half of the hollow tamping rod 3. The vibration shaft 5 rotates through the positioning ring 302 and slides in a manner that is reset by spring push. An L-shaped drive rod 5031 is welded on the vibration shaft 5. A guide wheel 50322 is rotatably mounted at the bottom end of each L-shaped drive rod 5031. Two positioning rings 301 are fixedly connected at an upper and lower interval on the inner bottom side of the hollow tamping rod 3. A triangular drive block 3011 is welded to the top of the upper positioning ring 301. A guide wheel 50322 rolls and abuts against the top ring surface of the positioning ring 301.

[0037] Preferably, the part of the vibration shaft 5 located between the positioning ring 302 and the lower bearing 6 is symmetrically fitted with two damping rings 502. The spring that pushes the vibration shaft 5 back to its original position is fitted on this part and its head and tail are fixedly connected to the two damping rings 502 respectively. This part is also welded with an installation ring 503.

[0038] The tail end of the L-shaped drive rod 5031 is welded and fixed to the outer periphery of the mounting ring 503.

[0039] Implementation 2 is based on Implementation 1, but with the following additions:

[0040] On the opposite side of each of the two damage reduction rings 502, a ring of steel balls 5021 is inlaid. The two rings of steel balls 5021 roll and abut against the positioning ring 302 and the mounting ring 503 respectively. The inner side of the top part of the vibration shaft 5 is fixedly connected to the positioning ring 301, and the bottom side of the outer ring of the upper bearing 6 abuts against the positioning ring 301.

[0041] The lower bearing 6 is located between the two locating rings 301 on the lower side.

[0042] Preferably, a polarizing strip 501 is provided protruding from the outer periphery of the vibration shaft 5.

[0043] Preferably, a soft tube 2 is connected between the drive motor 1 and the vibration shaft 5, and a flexible shaft 4 is threaded through the soft tube 2. The two ends of the flexible shaft 4 are connected to the rotating shaft of the drive motor 1 and the vibration shaft 5, respectively.

[0044] The following section provides a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of each feature, and their roles in realizing this technical solution:

[0045] In use, the hollow vibrator 3 is first inserted into the concrete to be vibrated. Then, the drive motor 1 is started. Through the power transmission of the flexible shaft 4, the drive motor 1 drives the vibration shaft 5 and the polarizing strip 501 to rotate at high speed. When the polarizing strip 501 is driven to rotate at high speed, it can generate an eccentric vibration effect. Under the action of this effect, the hollow vibrator 3 is driven to vibrate at high frequency, which compacts the concrete. This high-frequency vibration is carried out in the horizontal direction. When the vibration shaft 5 is driven to rotate at high speed, it drives an L-shaped drive rod 5031 and a guide wheel 50322 to roll along the top ring surface of the positioning ring 301. When the guide wheel 5032 rolls along the top ring surface, it successively abuts against the inclined surface of a triangular drive block 3011. When this abutting contact occurs, under the guiding effect of the inclined surface of the triangular drive block 3011, the guide wheel 5032 and the vibration shaft 5 are pushed upward. When the vibrating shaft 5 slides upward, the spring fitted on it is compressed by the positioning ring 301 and the lower loss-reducing ring 502. When the triangular drive block 3011 separates from the vibrating shaft 5 as it continues to rotate, the vibrating shaft 5 and the guide wheel 5032 lose the pushing and holding force from the triangular drive block 3011. They are automatically pushed down and reset by the counter-push of the compressed spring and impact the top ring surface of the positioning ring 301. Thus, through the inclined guiding effect of the triangular drive block 3011 and the counter-push effect of the spring, the vibrating shaft 5 can drive its body to vibrate up and down at high frequency when rotating at high speed. This, combined with the horizontal high-frequency vibration of the vibrating shaft 5, can perform compound dual vibration of concrete in both horizontal and vertical directions, which helps to improve the compaction effect and efficiency of the vibrating device on concrete and the practicality of the vibrating device.

[0046] Through the inclined plane guiding effect of a triangular drive block 3011, the up and down vibration operation of the vibrating shaft 5 can be driven by its own rotational driving force. This eliminates the need to configure an additional drive unit for the up and down vibration operation of the vibrating shaft 5, which helps to reduce the cost and power consumption of the vibrating device.

[0047] The spring that pushes the vibration shaft 5 back to its original position has two ends that indirectly abut against the positioning ring 302 and the mounting ring 503 through two wear-reducing rings 502. The two wear-reducing rings 502 can separate the two ends of the spring from the positioning ring 302 and the mounting ring 503, preventing the two ends of the spring from directly abutting against the positioning ring 302 and the mounting ring 503. Under the drive of the vibration shaft 5, the spring rotates relative to the positioning ring 302 and the mounting ring 503, which will cause excessive wear on the two ends of the spring and help extend the service life of the spring. The two rings of steel balls 5021 can reduce the relative wear between the two wear-reducing rings 502 and the positioning ring 302 and the mounting ring 503 through their rolling and guiding effect, thus extending the service life of the above components.
