Description

Technical Field

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

[0002] Concrete vibrators are key equipment used in construction to improve the density and strength of concrete. They eliminate air bubbles and reduce pores through vibration, ensuring uniform concrete distribution. One type of vibrator is the immersion vibrator (also known as an internal vibrator), which consists of a motor, a flexible shaft, and a vibrating rod. To use it, the vibrating rod is simply inserted vertically into the concrete pouring area.

[0003] When the concrete pouring area is large, multiple vibration points need to be selected according to the engineering specifications to ensure the vibration effect. Since the concrete pouring area is large, the construction workers cannot insert the vibrator into the preset vibration point outside the pouring area. Therefore, most construction methods involve setting up a support structure above the pouring area, and the construction workers stand on the support structure to carry out vibration construction. However, setting up the support structure requires manpower and material resources, which affects the construction efficiency. Utility Model Content

[0004] In view of this, the present invention proposes a concrete vibration device, the purpose of which is to enable construction workers to easily insert the vibrator into the preset vibration point outside the pouring area, thereby improving construction efficiency.

[0005] The solution provided by this utility model includes:

[0006] A concrete vibrating device, comprising:

[0007] A support frame, the bottom of which is equipped with casters;

[0008] A clamping assembly, which is hinged to the bracket about a horizontal pivot;

[0009] An extension rod is clamped onto the clamping assembly, and the two ends of the extension rod are defined as a hanging end and a handheld end, respectively.

[0010] A vibratory assembly, comprising a motor, a flexible shaft, and a vibratory rod;

[0011] A binding member is used to bind the flexible shaft to the extension rod, so that the vibrator is suspended below the hanging end of the extension rod.

[0012] As a further optional solution, the clamping assembly includes:

[0013] The first clamping block has a hinge at its bottom and a first clamping groove at its top.

[0014] The second clamping block has a second clamping groove at its bottom, and the first end of the second clamping block is hinged to the first end of the first clamping block.

[0015] A locking assembly for connecting the second end of the first clamping block and the second end of the second clamping block.

[0016] As a further optional solution, the locking assembly includes a locking bolt and a locking nut;

[0017] One end of the locking bolt is hinged to the second end of the first clamping block, and the locking nut is threadedly connected to the locking bolt;

[0018] The second end of the second clamping block has a recessed groove on its side for the locking bolt and locking nut to be inserted, and a pressing plate protruding from the groove for the locking nut to abut against.

[0019] As a further optional option, the binding element is a stainless steel band, nylon cable tie, or strap.

[0020] As a further alternative, the bracket includes a base and a vertical rod disposed on the base, with the clamping assembly hinged to the top of the vertical rod.

[0021] As a further alternative, the extension rod can be a steel pipe or a plastic pipe.

[0022] Compared with the prior art, the concrete vibrating device of this application has at least the following advantages:

[0023] 1. By suspending the vibrator at a high position using an extension rod, the placement radius of the vibrator is significantly increased compared to direct hand operation. This is especially suitable for large-area or deep foundation pouring scenarios, effectively covering vibration points that are difficult to reach with traditional hand operation, and expanding the vibration operation range.

[0024] 2. By hinged connection between the clamping assembly and the bracket, the construction personnel can control the handheld end of the extension rod to swing the hanging end up and down, thereby raising and lowering the vibrator. The operation is simple.

[0025] 3. The movable design of the support makes it easy to move between different vibration points. Attached Figure Description

[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] refer to Figure 1-5 An embodiment of this utility model illustrates a concrete vibration device, including a support 1, a clamping assembly 2, an extension rod 3, a vibration assembly 4, and a binding member 5; the bottom of the support 1 is provided with a movable wheel 13; the clamping assembly 2 is hinged to the support 1 around a horizontal pivot; the extension rod 3 is clamped on the clamping assembly 2, and the two ends of the extension rod 3 are defined as a hanging end 3a and a hand-held end 3b, respectively; the vibration assembly 4 includes a motor 41, a flexible shaft 42, and a vibrating rod 43; the binding member 5 is used to bind the flexible shaft 42 to the extension rod 3, so that the vibrating rod 43 is suspended below the hanging end 3a of the extension rod 3.

[0041] Specifically, the extension rod 3 is clamped onto the clamping assembly 2, which is located between the hanging end 3a and the handheld end 3b of the extension rod 3. Since the clamping assembly 2 is hinged to the bracket 1, the construction personnel can lift / lower the handheld end 3b to achieve the up-and-down swing of the hanging end 3a. The flexible shaft 42 of the vibrating assembly 4 is tied to the extension rod 3 using the binding piece 5, so that the vibrator 43 is suspended below the hanging end 3a of the extension rod 3. When the hanging end 3a swings up and down, the vibrator 43 can be lifted and lowered.

[0042] In application, both the support 1 and the construction personnel are located outside the pouring area. According to the preset vibration points, the support 1 is moved to a suitable position, and then the hanging end 3a of the extension rod 3 is swung downward so that the vibrator 43 is inserted into the poured concrete. After the vibration of the vibration point is completed, the hanging end 3a of the extension rod 3 is swung upward so that the vibrator 43 is lifted up. Then the support 1 is moved so that the hanging end 3a of the extension rod 3 is moved above the next vibration point. This operation is repeated to achieve vibration construction at multiple vibration points.

[0043] The position of the clamping component 2 on the extension rod 3 can be adjusted as needed. A more labor-saving method is to make the distance between the clamping component 2 and the handheld end 3b greater than the distance between the clamping component 2 and the hanging end 3a, thus saving effort by utilizing the lever principle. In this way, effort can be saved by reducing the weight of the extension rod 3, for example, by making the extension rod 3 a hollow structure such as a steel pipe or plastic pipe.

[0044] The working principle of the vibration component can be referred to the existing technology of the insertion vibrator. This embodiment does not improve on this aspect, so it will not be described in detail here.

[0045] In some embodiments, to facilitate the clamping and fixing of the extension rod 3 by the clamping assembly 2, such as... Figure 2 and Figure 4 As shown, the clamping assembly 2 includes a first clamping block 21, a second clamping block 22, and a locking assembly 23. The first clamping block 21 has a hinge portion 211 at its bottom and a first clamping groove 212 at its top. The second clamping block 22 has a second clamping groove 221 at its bottom, and the first end of the second clamping block 22 is hinged to the first end of the first clamping block 21. The locking assembly 23 is used to connect the second end of the first clamping block 21 and the second end of the second clamping block 22.

[0046] When the locking assembly 23 fixes the second end of the first clamping block 21 and the second end of the second clamping block 22, the extension rod 3 can be clamped between the first clamping groove 212 and the second clamping groove 221.

[0047] Specifically, to facilitate the locking of the first clamping block 21 and the second clamping block 22 by the locking assembly 23, as described above... Figure 2 and Figure 4 As shown, the locking assembly 23 includes a locking bolt 231 and a locking nut 232; one end of the locking bolt 231 is hinged to the second end of the first clamping block 21, and the locking nut 232 is threaded to the locking bolt 231; the side of the second end of the second clamping block 22 is recessed with a groove 222 for the locking bolt 231 and the locking nut 232 to be inserted, and a pressing plate 223 is protruding in the groove 222 for the locking nut 232 to abut against.

[0048] Thus, when the locking nut is loosened, the locking nut and locking bolt can be pulled out from the slot 222, allowing the second clamping block 22 to open and the extension rod 3 to be removed; when the locking nut is tightened, the locking nut can be pressed against the pressing plate 223 in the slot 222, causing the second clamping block 22 to press the extension rod 3 against the first clamping block 21, ensuring that the extension rod 3 is clamped stably.

[0049] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the binding member 5 can be a stainless steel band, nylon cable tie, or binding strap, which can be used to bind the flexible shaft 42 to the extension rod 3. In this embodiment, the binding member 5 is a stainless steel band, which can be adjusted for tightness and is reusable.

[0050] In some embodiments, such as Figure 1 As shown, the support 1 includes a base 12 and a vertical rod 11 disposed on the base 12, and the clamping assembly 2 is hinged to the top of the vertical rod 11. The base 12 provides stable support and prevents the support 1 from easily tipping over.

[0051] In summary, this application provides a concrete vibration device. This device suspends the vibrator 43 at a high position via an extension rod 3. Compared to direct hand-held operation, this significantly increases the placement radius of the vibrator 43, making it particularly suitable for large-area or deep foundation pouring scenarios. It effectively covers vibration points that are difficult to reach using traditional hand-held methods, expanding the vibration operation range. Through the hinged connection between the clamping assembly 2 and the support 1, the construction worker can control the handheld end 3b of the extension rod 3 to swing the suspended end 3a up and down, thereby raising and lowering the vibrator 43, simplifying operation. The movable design of the support 1 facilitates transfer between different vibration points.

[0052] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
