Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a low-disturbance vibrator for water conservancy engineering construction. Background Technology

[0002] Low-disturbance vibrators for water conservancy engineering construction are key tools in concrete pouring operations. Their main function is to eliminate air bubbles inside the concrete through low-amplitude, high-frequency vibration, thereby ensuring tight bonding of concrete aggregates and improving concrete density. At the same time, due to their "low-disturbance" characteristics, they can reduce the impact on surrounding poured concrete structures or foundations. They are especially suitable for parts of water conservancy projects such as dam anti-seepage walls and canal linings, where structural integrity requirements are high, ensuring the quality of concrete construction and the stability of the engineering structure.

[0003] Common models of low-disturbance vibrators, such as the "ZN-50D low-disturbance concrete vibrator," are mainly composed of three parts: the vibrator body, the flexible shaft, and the motor. The vibrator body is a cylindrical metal shell with an eccentric block and bearing inside. The rotation of the eccentric block generates low-amplitude vibration. The flexible shaft is a flexible transmission component, with one end connected to the bearing inside the vibrator and the other end connected to the output shaft of the motor to transmit power.

[0004] However, existing low-disturbance vibratory rods mostly rely on threads or simple sleeves for connection. Disassembly requires repeated rotation for alignment, resulting in low installation efficiency. Long-term use can easily lead to loosening due to vibration. Repairing or replacing vibratory rods takes a lot of time and affects the construction progress. Therefore, a low-disturbance vibratory rod for water conservancy engineering construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a low-disturbance vibrator for water conservancy engineering construction, aiming to improve the problems of cumbersome installation and disassembly processes and easy loosening due to vibration in the existing technology.

As a further description of the above technical solution: The locking assembly includes a locking tongue, which is fixedly connected to the bottom of the protective cover. The inside of the protective box is provided with a slot, and two locking blocks are slidably connected inside the slot. One end of each locking block is fixedly connected to a round rod, and a spring is sleeved on the outside of the round rod. As a further description of the above technical solution: A second hinge is fixedly connected to the outer side of the protective cover, and the other side of the second hinge is fixedly connected to the outer side of the protective box. As a further description of the above technical solution: A rotating handle is fixedly connected to the top of the screw, and a pressure block is fixedly connected to the outside of the screw, with the pressure block located below the rotating handle; As a further description of the above technical solution: The protective box has a circular groove inside, the circular rod is slidably connected inside the circular groove, a limit ring is fixedly connected inside the circular groove, and the circular rod is slidably connected inside the limit ring; As a further description of the above technical solution: An adjusting plate is fixedly connected to the outside of the locking block, and the adjusting plate is located on the outside of the protective box; As a further description of the above technical solution: Two heat dissipation meshes are installed on the outside of the protective box, and the heat dissipation meshes are located on both sides of the protective box; As a further description of the above technical solution: The top of the protective cover has a storage slot, and a handle is rotatably connected inside the storage slot.

[0007] This utility model has the following beneficial effects: 1.

[0011] 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.

[0012] Reference Figure 1 , Figure 5 and Figure 6 This utility model provides an embodiment of a low-disturbance vibrator for hydraulic engineering construction, comprising a protective box 1. The protective box 1 provides protection for key internal components, preventing the intrusion of dust, mud, and other impurities from the construction environment. A motor 11 is installed inside the protective box 1, serving as the power source for the vibrator. A connecting sleeve 18 is installed on the outside of the protective box 1, serving a connecting function. A connecting component is installed on the outside of the connecting sleeve 18, which is the core structure for achieving a detachable connection between the protective box 1 and the vibrating pipe 2, balancing connection strength and ease of assembly and disassembly. The connection component is convenient. A connecting pipe 3 is installed on the outside of the connecting component. A vibrating pipe 2 is installed at the other end of the connecting pipe 3. The vibrating pipe 2 directly contacts the concrete and other media in the construction of water conservancy projects. The high-frequency vibration achieves concrete compaction and reduces construction disturbance. A protective cover 4 is rotatably connected to the top of the protective box 1. The protective cover 4 can be opened and closed flexibly. When closed, it forms a complete closed space with the protective box 1. A locking component is installed inside the protective box 1. The locking component is used to fix the protective cover 4 after it is closed to prevent the protective cover 4 from loosening due to vibration during construction and to ensure the protective effect. The connecting assembly includes a sealing block 19, which is fixedly connected to one end of the connecting sleeve 18. The shape of the sealing block 19 is adapted to the groove 23, serving as a positioning and initial sealing function. A sealing block 20 is fixedly connected to one end of the connecting tube 3. The sealing block 20 and the sealing block 19 have complementary structures. After both are embedded in the groove 23, the connecting sleeve 18 and the connecting tube 3 can be connected. Two retaining rings 21 are installed on the outside of the connecting sleeve 18 and the connecting tube 3. The retaining rings 21 have grooves 23 inside. The sealing blocks 19 and 20 are engaged inside the grooves 23. The two retaining rings 21 are rotatably connected by a hinge 22. The hinge 22 provides an opening and closing fulcrum for the retaining rings 21, allowing the two retaining rings 21 to rotate around the hinge 22, making it easy to put on or remove from the connection. One end of the retaining rings 21 is fixedly connected to a... Edge 24, with a locking block 28 fixedly connected to the bottom of one edge 24. The locking block 28 is internally threaded with a screw 25. The screw 25 is rotatably connected to the inside of the two edges 24. The inside of the edge 24 has a circular hole slightly larger than the radius of the screw 25. Rotating the screw 25 can adjust the tightness of the fit between the two edges 24, thereby controlling the circumferential pressure of the retaining ring 21 on the connection point to ensure a firm connection. The top of the screw 25 is fixedly connected with a handle 26. The handle 26 is convenient for the operator to hold and rotate by hand, allowing adjustment of the screw 25 without the need for additional tools, improving the ease of disassembly and assembly. The outside of the screw 25 is fixedly connected with a pressure block 27. When the handle 26 is rotated to move the screw 25 downward, the pressure block 27 will gradually press the lower edge 24, tightly fitting the two edges 24 together through pressure. The pressure block 27 is located below the handle 26.

[0013] Reference Figures 1-4The locking assembly includes a latch 13, which cooperates with a locking block 14 to achieve locking. The latch 13 is fixedly connected to the bottom of the protective cover 4. A slot 12 is provided inside the protective box 1. When the protective cover 4 is closed, the latch 13 can be inserted into the slot 12, providing a basic positioning for locking. Two locking blocks 14 are slidably connected inside the slot 12, symmetrically distributed on both sides of the slot 12, and can slide horizontally along the inner wall of the slot 12. When the latch 13 is inserted into the slot 12, the locking blocks 14 can lock the latch 13, restricting its vertical movement. A round rod 16 is fixedly connected to one end of the locking block 14, and a spring 7 is sleeved on the outside of the round rod 16. Normally, the spring 7 is in a naturally extended state. When the latch 13 presses against the locking block 14, the spring 7 contracts under force, providing space for the locking block 14 to move. After the latch 13 is fully inserted, the spring... 7. The lock block 14 is reset and locked to the latch 13. A hinge 10 is fixedly connected to the outer side of the protective cover 4. The other side of the hinge 10 is fixedly connected to the outer side of the protective box 1. The hinge 10 allows the protective cover 4 to rotate around the pivot of the hinge 10, achieving flexible opening and closing. A circular groove 15 is provided inside the protective box 1. A circular rod 16 is slidably connected inside the circular groove 15. The circular groove 15 guides the sliding of the circular rod 16. A limit ring 17 is fixedly connected inside the circular groove 15. The limit ring 17 further strengthens the guiding and limiting effect on the circular rod 16, preventing the circular rod 16 from wobbling radially when sliding. The circular rod 16 is slidably connected inside the limit ring 17. An adjustment plate 6 is fixedly connected to the outer side of the lock block 14. The adjustment plate 6 is convenient for the operator to directly contact. The adjustment plate 6 is located on the outer side of the protective box 1.

[0014] Reference Figures 1-3 Two heat dissipation meshes 8 are installed on the outside of the protective box 1. The heat dissipation meshes 8 are located on both sides of the protective box 1. The heat dissipation meshes 8 are made of metal and have a surface covered with fine mesh holes, which can not only ensure air circulation, but also prevent dust, mud and other impurities from entering the interior of the protective box 1. The top of the protective cover 4 has a storage groove 9. The inside of the storage groove 9 is connected to a handle 5. When it is necessary to move or transport the vibrator, the operator can turn the handle 5 out of the storage groove 9 and hold the handle 5 to operate, which improves the convenience of transport.

[0015] Working principle: First, to prevent the motor 11 from getting dusty during construction, which could cause blockage and damage, a protective box 1 is set up and equipped with a protective cover 4 that can be easily opened and closed for maintenance. When the protective cover 4 is closed, simply put it on, and the locking tongue 13 will press the locking blocks 14 on both sides, causing the round rod 16 to move into the round grooves 15 on both sides. At this time, the spring 7 is compressed by force. When the locking tongue 13 is squeezed in, the locking blocks 14 will be stuck on the locking tongue 13. If it needs to be opened, simply slide the adjusting plate 6.

[0016] Secondly, when installing the vibratory pipe 2, simply rotate the handle 26 to make the screw 25 turn out, and the retaining ring 21 can open and close slightly. At this time, the sealing block 20 can be disengaged from the retaining ring 21, completing the quick disassembly function. If installation is required, simply align and insert the pipe, then rotate the handle 26 to make the pressure block 27 press against the edge 24, and firmly fix the edge 24 to achieve quick installation. In addition, the outer layer of the sealing block 19 and the sealing block 20 are both made of rubber, which can act as a sealing ring, enhance the sealing of the device, and effectively prevent mud and sand from entering.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
