Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibratory compaction technology for machine-made concrete, specifically a vibratory compaction device for machine-made sand concrete. Background Technology
[0002] Mechanized concrete typically refers to concrete prepared using manufactured sand as fine aggregate. As an important building material, manufactured concrete not only meets the requirements of modern construction projects for structural strength, durability, and ease of construction, but also offers advantages such as resource conservation, environmental friendliness, and economy. With continuous technological advancements and expanding applications, the importance of manufactured concrete in the construction field will become increasingly prominent, providing strong support for the sustainable development of construction projects.
[0003] Mechanized concrete vibration processing refers to the process of using mechanical vibration after concrete pouring to expel air bubbles and voids inside the concrete, thereby improving the density and uniformity of the concrete and ensuring the quality and durability of the concrete structure.
[0004] When vibrating manufactured concrete, workers typically insert the vibrator into the concrete. However, the insertion depth is difficult to control, resulting in either too deep or too shallow insertion. If the insertion is too shallow, the underlying concrete cannot be effectively vibrated, leading to a weak bond between the upper and lower layers. If the insertion is too deep, it will penetrate the underlying concrete and come into contact with the bottom formwork or reinforcing steel, damaging the concrete structure and affecting its quality. Utility Model Content
[0005] The purpose of this utility model is to provide a vibrating device for manufactured sand concrete to solve the problem mentioned in the background art that when using a vibrator to vibrate concrete, the depth of the vibrating end inserted into the concrete may be uneven due to the operator's operation, resulting in uneven vibration and affecting the internal density of the concrete and the overall performance of the structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating device for manufactured sand concrete, including a motor, a connecting line at the output end of the motor, and a limiting component at the other end of the connecting line for positioning the insertion depth of the vibrating end. The limiting component includes an extension rod at the other end of the connecting line, a chain rod and a vibrating rod at one end of the extension rod, a limiting plate on the outer wall of both the vibrating rod and the extension rod, and a pressure plate on the outside of the vibrating rod.
[0007] The outer wall of the extension rod is provided with multiple slots, each slot containing a ball bearing. A support plate is provided on the outer side of the ball bearing, and a spring is provided on the other side of the support plate. A protrusion is provided on the inner wall of the slot.
[0008] Preferably, one end of the connecting line is connected to the motor output end, and the other end passes through the extension rod and the chain rod and is connected to the vibration rod.
[0009] Preferably, the chain rod is composed of multiple chain links and can swing, and the two ends of the chain rod are respectively connected to an extension rod and a vibration rod.
[0010] Preferably, both limiting plates are connected to the outer walls of the vibrating rod and the extension rod respectively by bolts. The pressure plate is sleeved on the outside of the vibrating rod and is slidably connected to the outer wall of the vibrating rod. Multiple counterweights are provided on one side of the pressure plate.
[0011] Preferably, the plurality of the slot arrays are distributed on the outer wall of the extension rod, the ball is located in the slot and can roll on the inner wall of the slot, and one side of the ball extends out of the slot to the outside.
[0012] Preferably, the support plate is located in the slot and is slidably connected to the inner wall of the slot. One side of the support plate abuts against the ball bearing. Both ends of the spring are respectively connected to the inner wall of the slot and the support plate. The protrusion is located in the inner wall of the slot and is slidably connected to the inner wall of the slot, allowing it to slide and extend. The protrusion is electrically connected to the control remote controller.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By installing an extension rod at one end of the vibratory rod and fitting a pressure plate around the outside of the vibratory rod, the pressure plate adheres to the concrete surface and fits against the concrete surface when the vibratory rod is inserted into the concrete. The contact surface between the pressure plate and the concrete can guide and correct the angle of the vibratory rod insertion, reducing the probability and angle of tilted insertion. Furthermore, the position of the pressure plate as it slides on the vibratory rod helps to calculate the insertion depth, improving the operational standard of the vibratory rod insertion and ensuring the effective vibration of the concrete. In addition, the pressure plate can transmit the vibration generated by the vibratory rod to the concrete surface, improving the surface flatness and density.
[0015] 2. By setting multiple slots on the extension rod and loading ball bearings into the slots, and controlling the protrusions in the slots to slide out and lock with the support plate in the slots via remote control, the ball bearings are supported. This prevents the pressure plate from sliding further when it passes over the plate. At the same time, the resistance between the pressure plate and the concrete restricts the vibration rod, thereby enabling adjustment of the insertion depth of the vibration rod, improving the accuracy of the insertion depth control, and improving the quality of concrete vibration.
[0016] This invention improves the concrete compaction effect by installing a pressure plate on the outside of the vibrating rod. The pressure plate fits against the concrete surface when the vibrating rod is inserted, which helps to correct the angle during insertion and limits the insertion depth. In addition, the pressure plate can also improve the quality of concrete surface compaction by transmitting the vibration of the vibrating rod. Attached Figure Description

[0022] 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.
[0023] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.
[0024] Please see the appendix Figures 1-2 As shown, a vibratory compactor for manufactured sand concrete includes a motor 1. A connecting line 2 is provided at the output end of the motor 1 to connect the motor 1 to a vibratory rod 4. A limiting component for positioning the insertion depth of the vibratory end is provided at the other end of the connecting line 2. The limiting component includes an extension rod 3 at the other end of the connecting line 2. The extension rod 3 increases the sliding range of the pressure plate 5. A chain rod 301 and a vibratory rod 4 are provided at one end of the extension rod 3. The chain rod 301 reduces the vibration transmission from the vibratory rod 4 to the extension rod 3, improving the stability of the extension rod 3. The vibratory rod 4 can be inserted into the concrete to vibrate it. A limiting plate 401 is provided on the outer wall of both the vibratory rod 4 and the extension rod 3 to limit the sliding range of the pressure plate 5. A pressure plate 5 is provided outside the vibratory rod 4, sleeved on the outside of the vibratory rod 4, and can contact the concrete surface but not penetrate the concrete when the vibratory rod 4 is inserted into it.
[0025] One end of the connecting line 2 is connected to the output end of the motor 1, and the other end passes through the extension rod 3 and the chain rod 301 and is connected to the vibration rod 4. The chain rod 301 is composed of multiple chain links and can swing. The two ends of the chain rod 301 are connected to the extension rod 3 and the vibration rod 4 respectively. The two limiting plates 401 are connected to the outer walls of the vibration rod 4 and the extension rod 3 respectively by bolts. The pressure plate 5 is sleeved on the outside of the vibration rod 4 and is slidably connected to the outer wall of the vibration rod 4. Multiple counterweights are provided on one side of the pressure plate 5.
[0026] In this embodiment: during use, the pressure plate 5 slides towards the vibrating rod 4 under its own weight. Then, the connecting line 2 is pulled to insert the vibrating rod 4 into the concrete. During insertion, the pressure plate 5 is in contact with the concrete and floats on the concrete surface. The insertion of the vibrating rod 4 causes the pressure plate 5 to slide with it. The resistance between the pressure plate 5 and the concrete can guide the angle of the vibrating rod 4, reduce the amplitude of the deviation of the vibrating rod 4, and increase its vertical angle during insertion. At the same time, by observing the sliding position of the pressure plate 5 on the vibrating rod 4, the insertion depth can be calculated to improve the operation standard when inserting and vibrating the vibrating rod 4.
[0027] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 2-4 The extension rod 3 has multiple slots 6 on its outer wall to accommodate the ball bearings 7. Each slot 6 contains a ball bearing 7, with one end of the ball bearing 7 extending out of the slot 6. A support plate 8 is provided on the outer side of the ball bearing 7, fitting snugly against the ball bearing 7. With the help of a spring 801, the support plate 8 supports the ball bearing 7 and pushes one side of the ball bearing 7 out of the slot 6. A spring 801 is provided on the other side of the support plate 8, which supports the ball bearing 7 and provides a retraction range. When the ball bearing 7 is pressed, the spring 801 is compressed to retract. A protrusion 9 is provided on the inner wall of the slot 6. The protrusion 9 can slide and extend within the inner wall of the slot 6 via electronic control, thereby supporting and locking the support plate 8.
[0028] Multiple slots 6 are arrayed on the outer wall of the extension rod 3. Ball bearings 7 are located in the slots 6 and can roll on the inner wall of the slots 6. One side of the ball bearings 7 extends out of the slots 6. The support plate 8 is located in the slots 6 and is slidably connected to the inner wall of the slots 6. One side of the support plate 8 abuts against the ball bearings 7. The two ends of the spring 801 are connected to the inner wall of the slots 6 and the support plate 8 respectively. The protrusion 9 is located in the inner wall of the slots 6 and is slidably connected to the inner wall of the slots 6, and can slide to extend and retract. The protrusion 9 is electrically connected to the control remote control.
[0029] In this embodiment: Before vibrating the concrete, the protrusion 9 in the slot 6 at the corresponding height position of the extension rod 3 can be controlled by remote control to slide and extend, thereby locking the position of the support plate 8 and the ball bearing 7. When the pressure plate 5 slides to the extension rod 3 according to the insertion of the vibrating rod 4, the ball bearing 7 can be pressed to retract it before reaching the locked area of the ball bearing 7. When it encounters the locked ball bearing 7, the position of the pressure plate 5 is supported by the ball bearing 7, and the resistance between the pressure plate 5 and the concrete increases the resistance of the insertion of the vibrating rod 4, further limiting the insertion depth. By improving the standardization of operation, the quality effect of vibration is increased. In addition, the pressure plate 5 can transmit the vibration generated by the vibrating rod 4 to the concrete surface to achieve vibration, thereby improving the surface flatness and density.
