[0002] With the accelerating pace of water conservancy project construction, the requirements for construction equipment and devices in actual projects are becoming increasingly stringent. The concrete pouring effect is a crucial factor determining project quality. To ensure the compactness of the concrete, eliminate internal air bubbles, and enhance the interlayer bonding strength during layered pouring, construction workers need to manually vibrate the freshly poured concrete using a vibrator to meet the specifications for concrete pouring effect. However, manual vibration often relies on human experience and the equipment itself. Therefore, high-performance and practical vibrating devices have become an urgent need in engineering construction.

[0003] In existing concrete vibrators, the vibrating motor, vibrating rod, and hose are often fixedly connected, making it difficult to repair or replace a damaged component. Utility Model Content

[0035] The technical solution provided by this utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, this utility model provides a detachable concrete vibrating device, including a vibrating motor 1, a handle 2, and a vibrating rod 3. The vibrating motor 1 includes a main motor switch 7, a handle 8, a turntable base 9, an automatic cable reel 10, and an exciter. The handle 2 is equipped with a vibrating switch 19, a vibrating frequency adjustment knob 20, and an indicator light 21. A sleeve 16 is provided at the lower end of the handle 2. The exciter is connected to the vibrating switch 19 via a cable. A pressure sensor 23 is provided on the vibrating rod 3, and an accelerometer 24 and a low-frequency exciter 25 are installed inside the vibrating rod 3. The vibrating motor 1 and the vibrating rod 3 are connected via a flexible hose 4. The flexible hose 4, with a flexible shaft 6 as its inner core, passes through the inside of the sleeve 16. One end is detachably connected to the vibrating motor 1 via a connector 5, and the other end is detachably connected to the vibrating rod 3 via a connector 5. The sleeve 16 is detachably locked to the flexible hose 4 by a locking device (e.g., a stainless steel clamp).

[0037] Specifically, such as Figure 2 As shown, the connector 5 includes a base 501, a pin 502, a flexible housing 503, a water-sealing ring 504, a flexible shaft connector 505, a locking bolt 506, a clamp 507, and a groove 508.

[0038] At least two pins 502 are evenly arranged at the left end of the base 501; the flexible shaft connector 505 is located in the inner cavity of the flexible shell 503 with an opening at the right end, and its right end is also provided with a slot for fitting the flexible shaft 6 that penetrates the base 501 to better transmit the force of vibration; there is a gap between the flexible shaft connector 505 and the inner wall of the flexible shell 503 for fitting the pins 502; the inner wall of the flexible shell 503 is provided with a groove 508 for fitting the protrusion on the pins 502; the right end of the base 501 is fixed to the hose 4, and the left end of the flexible shell 503 and the left end of the flexible shaft connector 505 are both fixed to the vibrating motor 1 or the vibrating rod 3.

[0039] All pins 502 are evenly distributed at the front end of the base 501. In terms of shape, the front end of the base 502 is a truncated cone, with the top removed to form a frustum. The upper base of the frustum is parallel to the lower base, and the pins 502 are disposed on the upper surface of the frustum, generally evenly distributed circumferentially. In other words, the geometric center of the closed polygon formed by connecting the distribution points of all pins 502 (at least 3) coincides with the center of the circle on the upper surface, or two pins 502 are symmetrically distributed along the diameter of the upper surface. The distance between any distribution point and the center of the circle on the upper surface is greater than half the radius of the upper surface and less than the radius of the upper surface.

[0040] If the number and position of the slots 508 on the inner side of the flexible housing 503 correspond one-to-one with the pins 502, then when connecting the connector 5, each pin 502 must be aligned with the position of the slot 508. To achieve quick connection of the connector 5, all the slots 508 can be connected to form an annular slot with a cross-sectional depth, width, and shape consistent with the slots 508.

[0041] Optionally, a first connecting slope is provided at the right end opening of the inner wall of the flexible shell 503, and a water-sealing ring 504 is attached to it to fit into the second connecting slope, i.e. the side of the platform, to form a sealing layer and prevent water from the concrete from seeping in.

[0042] Optionally, such as Figure 3 As shown, the clamp 507 is fitted onto the outside of the flexible housing 503 and locked in place by the locking bolt 506. The locking bolt 506 includes a stud 5061 and a nut 5062. Nuts 5063 are fixed at both ends of the stud 5061 to prevent the stud 5061 and the nut 5062 from slipping off and being lost.

[0043] The main motor switch 7 is connected to the power indicator light 12. When the main switch is turned on, the green light on the power indicator light 12 illuminates; when the main switch is turned off, the power indicator light 12 turns off. An automatic reel 10 is installed at the front end of the vibrating motor 1. The automatic reel 10 is connected to an external cable 13. The other end of the cable 13 is connected to the handle 2 and is equipped with an adjustment slot 15. The cable 13 is covered with a cable protective sleeve 14.

[0044] Optionally, the sleeve 16 is divided into an inner sleeve and an outer sleeve, with a vibration-damping and cushioning material 18 filling the space between them. Inside the outer sleeve, at least one locking clamp 17 is fitted onto the inner sleeve to lock the hose, thus securing the handle 2 to the hose 4. Correspondingly, the outer sleeve has a hole to expose the top of the screw used to adjust the locking clamp 17, facilitating tightening or loosening the screw with a screwdriver to secure the handle 2 to the hose 4 or to remove the handle 2 from the hose 4.

[0045] The vibration frequency adjustment knob 20 includes a pointer 29 and adjustment positions, namely a low-frequency position 30, a high-frequency position 31, and a hybrid position 32. Three indicator lights 21 are located at the front of the handle 2: a working indicator light 2101, a fault indicator light 2102, and a vibration indicator light 2103. Sound-absorbing cotton 26 is filled between the outer shell of the vibrator 3 and the internal low-frequency vibrator 25. A pressure sensor 23 is connected to the outer wear-resistant ceramic layer 27 of the vibrator 3 via a miniature guide rod 28. The pressure sensor 23 and the accelerometer 24 are connected to the monitoring unit 22 located on the handle via cable or wireless signal. The low-frequency vibrator 25 is connected to the vibration frequency adjustment knob via cable.

[0046] The vibratory motor 1, the handle 2, and the vibrating rod 3 are all equipped with cable interfaces to enable detachable cable connections.

[0047] Workflow: During use, the construction worker moves the vibratory motor 1 to the construction site, connects the matching flexible hose 4, inserts it into the handle 2, and connects the external cable 13 of the vibratory motor 1. The clamp 17 is then tightened to secure the handle 2. The other end of the flexible hose 4 is connected to the vibrating rod 3. Before use, first turn on the main motor switch 7. When the green light on the main switch illuminates, the worker can hold the handle 2 to begin vibration. During vibration, turn on the vibration switch 19. When both the work indicator light 2101 and the vibration indicator light 2102 illuminate green simultaneously, adjust the vibration frequency using the vibration frequency adjustment knob 20.

[0048] like Figure 4 As shown, in the vibration frequency adjustment knob 20, when it is in the low-frequency setting 30, only the low-frequency exciter 25 inside the vibrator rod 3 works, suitable for small projects, narrow spaces, or shallow concrete vibration. When it is in the high-frequency setting 31, only the exciter inside the vibration motor 1 works, suitable for large projects and deep concrete vibration. When it is in the mixed setting 32, the exciter inside the vibration motor 1 and the low-frequency exciter 25 inside the vibrator rod 3 work simultaneously, suitable for high-strength concrete vibration. Combining the high-frequency setting with the low-frequency setting can make the vibration effect more uniform. Insert the vibrator rod 3 into the newly poured concrete to a certain depth for vibration. When the red light of the vibration indicator 2102 illuminates, it indicates that the concrete has been compacted, and the next vibration position can be changed.

[0049] If the fault indicator light 2103 illuminates, it indicates that the pressure sensor 23 and accelerometer 24 have detected a discrepancy between the vibration and the set value, requiring immediate removal and maintenance. The internal pressure of concrete varies with depth; at the same depth, the internal pressure of different concrete specifications also differs. Therefore, when the internal pressure detected by the pressure sensor 23 does not match the internal pressure value corresponding to the current depth and concrete specification, the monitoring unit generates a trigger signal for the fault indicator light 2103, causing it to illuminate. Furthermore, when the concrete density is uneven, the vibrator 3 will generate irregular movement trajectories in that area. Therefore, when the acceleration segment detected by the accelerometer 24 changes its acceleration direction more than the preset value per unit time (second), causing a sudden change in acceleration, the monitoring unit generates a trigger signal for the fault indicator light 2103, causing it to illuminate.

[0050] In summary, compared with the prior art, the technical solution provided by this utility model allows the vibration motor, hose and vibrating rod to be detached from each other, facilitating individual repair or replacement of individual components; the flexible shaft is fitted into the slot on the flexible shaft connector, enabling efficient transmission from the vibration motor to the vibrating rod on a detachable basis; and the disassembly of multiple components during non-working phases or transportation can save storage space.

[0051] Furthermore, multiple pins ensure a stable connection at the joint; the annular groove allows for a snug fit even when the pins are not fully aligned; the sealing layer prevents moisture from seeping into the joint; locking bolts and clamps make the joint connection more stable, and nuts at both ends prevent studs or nuts from being lost; the handle with vibration-damping material reduces vibration amplitude and improves the comfort of the worker; pressure sensors and accelerometers provide the worker with a basis for adjusting the vibration frequency, making the vibration operation more reasonable and precise, avoiding under-vibration or over-vibration; and the sound-absorbing cotton filling the vibrator reduces noise pollution from vibration.

[0052] In addition, the handle facilitates the transfer and movement of the motor during construction; the base can protect the motor by isolating it from concrete slurry during construction, and the turntable design can reduce the frequency of motor movement during construction; the automatic cable reel can reel in and unload the cable, preventing the cable from being corroded by being dragged in concrete slurry.
