Description

Technical Field

[0001] This utility model relates to the field of vibration technology, and in particular to a novel pull-type vibration device with a twisted block design. Background Technology

[0002] Twisted kingpin blocks are widely used as the core facing structure in hydraulic engineering projects such as breakwaters and revetments due to their excellent wave-dissipating performance and stability. However, their complex irregular geometry (multi-limbed rods, non-coplanar inclined surfaces) makes concrete vibration during prefabrication extremely difficult, especially in the sloping areas of the lower and middle limbs, where quality defects such as air bubbles and honeycomb pitting are prone to occur.

[0003] The aforementioned quality defects are mainly attributed to the limitations of traditional vibration methods. The traditional method of manually holding the vibrator with one hand makes it difficult to accurately control the vibration angle, especially when constructing on sloping surfaces. The vibrator cannot maintain the preset tilt angle, causing air bubbles to accumulate on the slope and not be able to escape. Furthermore, the operator needs to adjust the vibrator's posture based on experience throughout the process, which is labor-intensive and unstable. Fatigue can easily lead to uneven vibration, exacerbating concrete segregation and rotten concrete. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a novel pull-type vibratory device for twisted blocks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel pull-type vibratory compaction device for twisted blocks includes a vibrator, which includes an electric motor, a flexible shaft connected to the electric motor, and a vibratory rod disposed at the end of the flexible shaft. A handle is fixed to the flexible shaft, and a connecting part is provided between the handle and the vibratory rod. A first lifting ring is fixed to the vibratory rod, and a lifting rope is fixed to the first lifting ring. A pull ring is fixed to the end of the lifting rope away from the first lifting ring.

[0007] Preferably, the vibrating rod adopts a double eccentric wheel structure and the vibration frequency is 100-150Hz.

[0008] Preferably, the connecting part includes a first connecting ring fixed to the lower side of the handle, a second connecting ring fixed to the vibrating rod, and a connecting plate hinged between the first connecting ring and the second connecting ring.

[0009] Preferably, a second lifting ring is fixed to the first connecting ring via a connecting rod, and the lifting rope is slidably connected inside the second lifting ring.

[0010] Preferably, the lifting rope is a plastic-coated steel wire rope with a diameter of 2mm, and the tensile strength of the lifting rope is ≥500N.

[0011] Preferably, the outer side of the handle is covered with a sponge sleeve, and the sponge sleeve is provided with anti-slip grooves for hand gripping.

[0012] Compared with the prior art, this utility model provides a novel pull-type vibratory compaction device with a twisted block design, which has the following beneficial effects:

[0013] 1. This new type of pull-type vibratory compaction device for twisted blocks replaces manual experience judgment with a dual-anchor segmented force application mode, which can effectively eliminate the blind zone of vibration on the slope surface and ensure that the vibratory rod always maintains the preset inclination angle during slope construction. It overcomes the problem of vibration angle deviation caused by unstable manual holding in traditional methods and is suitable for vibration construction of irregular concrete components such as twisted blocks.

[0014] 2. This novel pull-type vibratory compactor, with its connecting part, allows the handle to drive the flexible shaft and vibratory rod directly lateral within the concrete after the concrete in a certain area has been vibrated. This solves the problem of the complicated steps in the existing technology where the flexible shaft is too soft to move directly lateral within the concrete, requiring the vibratory rod to be moved out of the concrete and then laterally lowered to the vibration area, thus improving vibration efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] like Figures 1 to 4 As shown, this embodiment proposes a novel pull-type vibratory device for twisted blocks, including a vibrator 1. The vibrator 1 includes a motor 101, a flexible shaft 102 connected to the motor 101, and a vibratory rod 103 disposed at the end of the flexible shaft 102. A handle 2 is fixed on the flexible shaft 102, and a connecting part 3 is provided between the handle 2 and the vibratory rod 103. A first lifting ring 1031 is fixed on the vibratory rod 103, and a lifting rope 4 is fixed on the first lifting ring 1031. A pull ring 401 is fixed at one end of the lifting rope 4 away from the first lifting ring 1031.

[0024] Specifically, the vibrator 1 is existing technology. When the vibrator 1 is working, the motor 101 is placed on top of the torsion block mold. Controlling the operation of the motor 101 causes it to transmit rotational power through the flexible shaft 102 to the double eccentric wheels inside the vibrating rod 103, causing the vibrating rod 103 to generate a vibration frequency of 100-150Hz. The operator controls the position of the flexible shaft 102 through the handle 2, and applies directional tension to the vibrating rod 103 by pulling the lifting rope 4 through the pull ring 401. The anchor point torque balance principle precisely adjusts the spatial posture of the vibrator 103. The lifting rope 4 is a 2mm diameter plastic-coated steel wire rope with a tensile strength ≥500N. This application is applicable to the vibration construction of irregularly shaped concrete components such as T-shaped blocks. By replacing manual experience judgment with a dual-anchor point segmented force application mode, it can effectively eliminate the blind zone of vibration on the slope surface, ensuring that the vibrator 103 always maintains the preset inclination angle during slope construction, overcoming the problem of vibration angle deviation caused by unstable manual holding in traditional methods. Construction verification shows that when constructing irregularly shaped components such as T-shaped blocks, the air bubble rate on the concrete slope surface is reduced by more than 40%, the uniformity of density is improved by 35%, and the operator's fatigue intensity is reduced by 40% compared to the traditional single-handed holding method.

[0025] It should be noted that a sponge sleeve 5 is provided on the outer side of the handle 2, and the sponge sleeve 5 is provided with anti-slip grooves 501 for hand gripping; the sponge sleeve 5 improves the grip comfort of the staff, and the anti-slip grooves 501 help improve the stability of the staff's grip on the flexible shaft 102.

[0026] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the connecting part 3 further includes a first connecting ring 301 fixed to the lower side of the handle 2, a second connecting ring 302 fixed to the vibrating rod 103, and a connecting plate 303 hinged between the first connecting ring 301 and the second connecting ring 302.

[0027] Workers connect and limit the flexible shaft 102 and the vibrator 103 through the connecting part 3. When the lifting rope 4 pulls the vibrator 103, the vibrator 103 rotates at the hinged position with the connecting plate 303, thereby adjusting the vibration angle of the vibrator 103. At the same time, by setting the connecting part 3, after the concrete in a certain area is vibrated, the handle 2 drives the flexible shaft 102 and the vibrator 103 to move directly laterally in the concrete through the connecting part 3. This solves the complicated steps in the prior art where the flexible shaft 102 is too soft to move directly laterally in the concrete, and the vibrator 103 needs to be moved out of the concrete and then moved laterally to the concrete vibration area, which is convenient for improving vibration efficiency.

[0028] It should be noted that a second lifting ring 3011 is fixed on the first connecting ring 301 by a connecting rod, and the lifting rope 4 is slidably connected inside the second lifting ring 3011; by setting the second lifting ring 3011, the direction of the pulling force of the lifting rope 4 can be constrained and guided.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
