[0035] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0036] Reference Figures 1 and 2 This embodiment provides a large-volume concrete vibrating device, comprising an energy storage module 1, a connecting pipeline 2, and a vibrating rod 3. The connecting pipeline 2 is connected to the energy storage module 1 and the vibrating rod 3 at both ends, respectively. The energy storage module 1 is used to supply energy to the vibrating rod 3 for vibrating. The connecting pipeline 2 is provided with depth markings 21. Several depth markings 21 are provided and are evenly spaced along the axial direction of the connecting pipeline 2.

[0037] Reference Figures 1 and 2 The distance between two adjacent depth marks 21 is 20 cm, 30 cm or 50 cm. Therefore, when the vibrating rod 3 descends during the operation, the user can evaluate the depth position of the vibrating rod 3 by recording the number of depth marks 21 immersed in the concrete mortar liquid surface 521, thereby avoiding the problem of blind detection in traditional technology that causes the vibrating rod 3 to be unable to descend to the bottom of the concrete mortar 52 for vibration operation, thereby improving the vibration effect of the bottom concrete mortar 52 and avoiding the occurrence of vibration blind spots.

[0038] Reference Figures 3 and 4 Each depth marker 21 includes a dark coating 211 and a fluorescent coating 212 connected at their ends. The connecting pipeline 2 comprises a base tube 201 and a reinforcement layer 202 disposed on the outer surface of the base tube 201. The dark coating 211 and the fluorescent coating 212 are disposed between the base tube 201 and the reinforcement layer 202. The reinforcement layer 202 protects the dark coating 211 and the fluorescent coating 212 from external wear, thereby increasing the service life of the present invention. The base tube 201 is made of a light-colored material (e.g., yellow, gray, etc.), while the dark coating 211 is a dark-colored material (e.g., purple, black, etc.), creating a sharp color contrast and facilitating the counting of the depth markers 21 during daytime operations. The fluorescent coating 212 is made of a fluorescent material, making it easier for operators to count the depth markers 21 during nighttime operations (operators can use a flashlight to illuminate the fluorescent material as needed). The reinforcement layer 202 is transparent to avoid affecting the color rendering of the dark coating 211 and the fluorescent coating 212. The base tube 201 is made of rubber material to ensure excellent flexibility.

[0039] Reference Figure 5The vibrator 3 includes a housing 31, a counterweight 32, and a vibration assembly 33. The counterweight 32 is fixedly mounted on the end of the housing 31, away from the connecting pipeline 2. The vibration assembly 33 is fixedly mounted on the end of the housing 31, closer to the connecting pipeline 2.

The energy storage module 1 is equipped with a battery, and the vibration assembly 33 is equipped with a vibration motor. The battery is connected to a power switch via a wire, and the power switch is connected to the vibration motor via a wire.

[0040] Reference Figure 6 The housing 31 includes two half-shells 3101 connected by bolts, and a sealing ring is provided at the connection position, so as to install the counterweight block 32 and the vibration assembly 33 to realize the assembly of the vibrator 3. The left and right half-shells 3101 are spliced ​​together to form a complete and sealed housing 31.

[0041] Reference Figure 5 The shell 31 includes an end shell 311, a main shell 312, a tail shell 313 and an extension tube shell 314; the main shell 312 is in the shape of a cylinder with openings at both ends; the end shell 311 is conical and fixedly connected to the end of the main shell 312 away from the connecting pipeline 2 (fixed connection through an integrated seal); the tail shell 313 is in the shape of a truncated cone with openings on both sides, and the tail shell 313 is fixedly connected to the end of the main shell 312 close to the connecting pipeline 2 (fixed connection through an integrated seal); the extension tube shell 314 is in the shape of a cylinder, one end of the extension tube shell 314 is fixedly connected to the tail shell 313 (fixed connection through a hot melt seal), the extension tube shell 314 is sleeved on the outer surface of the connecting pipeline 2, and the inner wall of the extension tube shell 314 is fixedly connected to the outer wall of the connecting pipeline 2 by a hot melt seal, so that the vibrator 3 has excellent sealing performance. The extension tube shell 314 is used to avoid stress concentration at the connection position of the connecting pipeline 2 and the vibrating rod 3, thereby increasing the service life of the utility model.

[0042] Reference Figure 5 The two ends of the counterweight 32 are respectively placed in the inner cavity of the end shell 311 and the inner cavity of the main shell 312. The outer surface of the end of the counterweight 32 away from the connecting pipeline 2 is adapted and fits with the inner wall of the end shell 311, so that the counterweight 32 can be stably installed in the inner cavity of the shell 31. When vibrating, the vibrating rod 3 is in a vertical state and the center of gravity of the vibrating rod 3 is located at the bottom. This can prevent the vibrating rod 3 from shaking during longitudinal movement, reduce the degree of inclination of the vibrating rod 3, and further reduce the risk of the vibrating rod 3 being stuck in the steel mesh 51 after tilting.

[0043] Reference Figure 5 and Figure 6The vibration component 33 is fixedly installed in the inner cavity of the main shell 312 by bolts; the right end of the counterweight block 32 is fixedly installed in the inner cavity of the main shell 312 by bolts.

[0045] Reference Figure 7 The large-volume concrete vibrating device also includes a limiting assembly 4 capable of clamping the connecting pipeline 2; the limiting assembly 4 includes a supporting frame 41 and a crimping crank 42 that can rotate with each other. The supporting frame 41 and the crimping crank 42 can clamp the connecting pipeline 2 from both sides, and the clamped position of the connecting pipeline 2 is bent, thereby fixing the limiting assembly 4 on the connecting pipeline 2. During construction, the limiting assembly 4 is placed horizontally and crimped onto the steel mesh 51. At this time, human intervention in the connecting pipeline 2 is removed, and the vibration plate can be suspended at a specific depth position to achieve targeted overtime vibration of the concrete mortar 52 at the specific depth position.

[0046] Reference Figure 8 The support frame 41 is U-shaped and has a rotating shaft 411 at its opening. The two ends of the rotating shaft 411 are fixedly connected to the inner wall of the support frame 41 (for example, by bolts inserted radially along the rotating shaft 411, and the support frame 41 has accommodating grooves for accommodating the two ends of the rotating shaft 411). The crimping crank 42 includes a crimping rod 421 and a sleeve 422 fixedly connected in a T-shape (for example, by an integral fixed connection or by welding). The end of the crimping rod 421 is connected to the middle of the surface of the sleeve 422, and the sleeve 422 is sleeved on the surface of the rotating shaft 411. The crimping rod 421 and the sleeve 422 can rotate synchronously with the rotating shaft 411 as the center.

[0047] Reference Figure 7 An arc-shaped portion 4211 is provided in the middle of the crimping rod 421 , and the outward convex direction of the arc-shaped portion 4211 is away from the direction of the support frame 41 , so that the arc-shaped portion 4211 can adapt to clamp the connecting pipeline 2 .

[0048] Reference Figures 7 to 9, a screw hole 412 is provided on the upper surface of the end of the support frame 41 away from the rotating shaft 411, and a crimping plate 423 is provided on the end of the crimping rod 421 away from the sleeve 422. The crimping plate 423 is provided with a mounting hole 4231 adapted to the screw hole 412. When the crimping plate 423 is crimped onto the upper surface of the support frame 41, the screw hole 412 and the mounting hole 4231 are coaxial. The limiting assembly 4 also includes a mounting bolt adapted to the screw hole 412. The user uses the support frame 41 and the crimping crank 42 to clamp the connecting pipeline 2 from the upper and lower sides, and then presses the crimping plate 423 on the surface of the support frame 41, penetrates the mounting bolt through the mounting hole 4231 and tightens the screw hole 412 to achieve clamping and fixation of the limiting assembly 4.

[0049] Reference Figure 9 The pressing plate 423 is fixedly connected to the upper surface of the pressing rod 421, and the pressing plate 423 and the pressing rod 421 are arranged in a Z shape.

[0050] Reference Figure 10 The outer wall of the support frame 41 is fixedly connected to two claws 413. The two claws 413 are respectively arranged at the left and right ends of the same side wall of the support frame 41, one claw 413 is close to the screw hole 412, and the other claw 413 is close to the rotating shaft 411. The two claws 413 are arranged in parallel. The claws 413 are fixedly connected to the support frame 41 in an integrated manner.

[0051] Usage method 1: ① Assemble the mold 5 and the steel mesh 51, and pour concrete mortar 52 into the inner cavity of the mold 5 until the concrete mortar liquid level 521 is flush with the top surface of the steel mesh 51; ② The user grasps the connecting pipeline 2, turns on the switch of the energy storage module 1, and vertically lowers the vibrating rod 3 along the gap of the steel mesh 51 to vibrate the concrete mortar 52 at different depths; in this process, the number of depth marks 21 immersed in the concrete mortar liquid level 521 is manually recorded to evaluate the depth of the vibrating rod 3.

[0052] Usage method 2: ① Assemble the mold 5 and the steel mesh 51, and pour concrete mortar 52 into the inner cavity of the mold 5 until the concrete mortar liquid level 521 is flush with the top surface of the steel mesh 51; ② According to the target lowering depth, clamp the limit component 4 on the connecting pipeline 2 at the appropriate depth mark 21 (for example, if it is necessary to perform targeted vibration on the concrete mortar 52 at a depth of 5 meters, select the connecting pipeline 2 with a depth mark 21 interval of 50 cm, and clamp the limit component 4 on the connecting pipeline 2 at the fourth depth mark 21); ③ The user grasps the connecting pipeline 2 and lowers the vibrating rod 3 vertically along the gap of the steel mesh 51 (at this time, the limit component 4 is in an upright position), so that the claw 413 is stuck on the steel bars on the left and right sides of the gap of the steel mesh 51; ④ The user turns on the switch of the energy storage module 1 to carry out targeted vibration construction.

[0053] The concrete mortar 52 adhered to the surface of the connecting pipe 2 gradually falls off due to vibration, or the user can regularly flush the connecting pipe 2 to prevent the concrete mortar 52 from covering the depth marking 21, thereby ensuring the visibility of the depth marking 21. If flushing is not possible, the user can also assess the depth of the vibrator 3 by observing the traces of concrete mortar 52 on the surface of the connecting pipe 2 or the number of depth markings 21 not covered by concrete mortar 52.

[0054] The utility model has a simple structure and reliable functions. The energy storage module 1 can control the vibrating rod 3 to drive the vibrating rod 3 to vibrate; the vibrating rod 3 moves downward along the gaps in the steel mesh 51 to vibrate the concrete mortar 52. The connecting pipeline 2 serves as a connection between the energy storage module 1 and the vibrating module; the connecting pipeline 2 is provided with a number of depth marks 21 arranged at equal intervals. The depth marks 21 have excellent visibility. The user records the number of depth marks 21 immersed in the concrete mortar liquid surface 521 to evaluate the depth of the vibrating rod 3, so as to facilitate the subsequent adjustment of the position of the vibrating rod 3, so that the vibrating rod 3 can move downward as far as possible to the bottom of the mold cavity 5 for vibration operation, thereby avoiding the vibration blind spot of the concrete mortar 52 at the bottom of the mold cavity 5, and ultimately improving the quality of large-volume concrete components.
