Description

Technical Field

[0001] This utility model relates to the technical field of concrete vibration devices, specifically a concrete vibration device. Background Technology

[0002] Concrete vibrators are key equipment in concrete construction. Their main function is to remove air bubbles from the concrete by vibrating the vibrator rod after it is inserted into the concrete.

[0003] Initially, workers stood in the concrete, moving vibrators to different positions for vibration. Later, concrete vibrating machines appeared, with the vibrator itself able to move left and right along a track to change the vibration position. A fully automatic vibrator consists of a housing, a telescopic frame, a winding and unwinding device, a flexible shaft, and vibrators. The housing houses a control device. One end of the telescopic frame is fixed to the housing, while the other end allows the vibrator to pass through. Extending and retracting the telescopic frame changes the distance between the vibrator and the housing to adapt to different construction sites. One end of the flexible shaft connects to the vibrator, and the other end connects to the control device. The flexible shaft is wound onto the winding and unwinding device. When the winding and unwinding device releases the flexible shaft, the vibrator can be lowered into the concrete; when the winding and unwinding device rewinds the flexible shaft, the vibrator can be lifted to detach from the concrete and return to its original position at the telescopic frame.

[0004] In the existing technology, a large amount of moisture and less concrete remain on the coiled flexible shaft and vibrator, and the residue on the outer wall of the flexible shaft and vibrator cannot be cleaned in time during the coiling process. This leads to site pollution during the relocation of the vibrator body, and if the moisture and concrete are not cleaned in time and harden, it will cause jamming or reduced vibration efficiency during the next use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-5 .

[0017] This utility model provides a concrete vibration device, including a vibration device body. The vibration device body includes a shell, a telescopic frame 1, a winding and unwinding device, a flexible shaft 2, and a vibrating rod 3. A control device is installed inside the shell. One end of the telescopic frame 1 is fixed to the shell, and the other end allows the vibrating rod 3 to pass through. By extending and retracting the telescopic frame 1, the distance between the vibrating rod 3 and the shell can be changed to adapt to different construction sites. One end of the flexible shaft 2 is connected to the vibrating rod 3, and the other end is connected to the control device. The flexible shaft 2 is wound onto the winding and unwinding device. When the winding and unwinding device releases the flexible shaft 2, the vibrating rod 3 can be lowered into the concrete. When the winding and unwinding device winds up the flexible shaft 2, the vibrating rod 3 can be lifted to detach from the concrete and return to its original position at the telescopic frame 1. The cross-sectional perimeter of the flexible shaft 2 is greater than the cross-sectional perimeter of the vibrating rod 3. The vibration device body is prior art and will not be described in detail here.

[0018] Figure 1 The telescopic frame 1 has two support plates 4 arranged vertically, namely the first support plate 4a and the second support plate 4b. A material passage hole 5 is provided through the support plate 4 along its height direction. A chamber 8 is provided in the first support plate 4a along its horizontal direction, and the opening d of the chamber 8 communicates with the material passage hole 5. The bearing includes an inner ring 60, balls, a ball support, and an outer ring 61; this is prior art.

[0019] A rotating component 6 is located in one of the support plates 4, and the rotating component 6 is a bearing.

[0020] Figure 3-4 A bearing is installed inside the chamber 8, and the inner ring 60 is concentrically embedded at the opening d of the chamber 8. The inner ring 60 is connected to the support plate 4 through a rotary seal to prevent concrete, dust and other liquids from entering the chamber 8 and to play a sealing role.

[0021] Figure 2 The two ends of the rope 7 are the m end and the n end, respectively. The n end of the rope 7 is fixed on the second support plate 4b, and the m end of the rope 7 is fixed on the inner ring 60. The total length of the rope 7 is greater than the maximum value of the cross-sectional perimeter of the vibrator 3. Ideally, the total length of the rope 7 is 1.5 times the cross-sectional perimeter of the vibrator 3.

[0022] The power mechanism is located inside chamber 8, and it controls the rotation direction and start / stop of the inner ring 60.

[0023] Figure 5 During the lowering of the vibrating rod 3, the power mechanism does not operate, and the rope 7 wraps around the outer wall of the vibrating rod 3 or the flexible shaft 2 0 times, with both ends of the rope 7 on the same vertical line. During the lifting of the vibrator 3, the flexible shaft 2 first passes the vibrator 3 through the support plate 4. Before the lifting begins, the power mechanism drives the inner ring 60 to rotate, the inner ring 60 drives the m end to rotate, and the m end drives the rope 7 to wrap around the outer wall of the flexible shaft 2 until the rope 7 is fully tightened, so that several loops of rope 7 are wound and attached to the outer wall of the flexible shaft 2, forming several scraping rings, which are similar in shape to springs. At this time, the diameter of the scraping rings is matched with the diameter of the flexible shaft 2. When the flexible shaft 2 and the vibrator 3 are lifted, the flexible shaft 2 passes through the scraping rings, and the concrete on the outer wall of the flexible shaft 2 is scraped off the flexible shaft 2 and falls back into the lowered concrete material, similar to the flexible shaft 2 passing through the center of the spring along the axis of the spring. After scraping off the flexible shaft 2, the power mechanism drives the inner ring 60 to rotate in the opposite direction, which in turn drives the m end to rotate in the opposite direction, so as to release the rope 7 and return the rope 7 to its initial state of no longer being wrapped. Once the top of the vibrating rod 3 reaches between the two support plates 4, the power mechanism drives the inner ring 60 and the m end to rotate again. Similarly, the m end drives the rope 7 to wrap around the outer wall of the vibrating rod 3, forming a scraping ring that matches the diameter of the vibrating rod 3. Because the diameter of the vibrating rod 3 is larger than that of the flexible shaft 2, the number of loops of the rope 7 is reduced at this time. Similarly, when the vibrating rod 3 is lifted, it passes through the scraping ring, and the concrete on the outer wall of the vibrating rod 3 is scraped off the vibrating rod 3 and falls back into the lowered concrete material.

[0024] If any residual concrete remains at the tip of the vibrator 3, the power mechanism can rotate end m slightly in the opposite direction to loosen the rope 7. Then, the vibrator 3 can be lowered again until its tip reaches the scraper ring. The power mechanism then rotates forward to rewind the rope 7, coordinating with the lifting of the vibrator 3 to scrape away the remaining concrete. Repeating this process multiple times will completely clean the area. Therefore, this device can wrap around the flexible shaft 2 or vibrator 3 multiple times and then tighten to form a scraper ring of the appropriate diameter. During the rewinding and lifting of the vibrator 3, it automatically scrapes off residue from the flexible shaft 2 and the outer surface of the vibrator 3, achieving timely cleaning and preventing secondary contamination and impact on future use.

[0025] Some vibrating rods 3 have a conical bottom and some have a cylindrical bottom; this device can be used for both, as long as the working diameter of the scraper ring is set correctly.

[0026] Because the two support plates 4 are at different heights, each scraper ring is inclined relative to the axis of the vibrator 3, and its shape is similar to a stretched spring. The inclined rope 7 can better scrape and separate the concrete, so that the scraped concrete can slide down along the inclined rope 7 and avoid the concrete from accumulating on the surface of the rope 7.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0028] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0030] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
