Description

Technical Field

[0001] This utility model relates to the field of concrete vibration construction, and in particular to an adjustable concrete vibration device. Background Technology

[0002] In the field of civil engineering bridges, the quality of concrete pouring for crash barriers is crucial. Currently, immersion vibrators are commonly used for compaction during construction. However, for crash barriers with a horseshoe-shaped cross-section, the internal reinforcement is densely packed, and the working space is extremely narrow. Traditional vibrators, due to their large diameter and non-adjustable structural rigidity, struggle to effectively penetrate the gaps between the formwork and the reinforcement, especially in the horseshoe-shaped corner area, easily creating blind spots for compaction. This results in insufficient concrete density in these areas, preventing air bubbles from escaping smoothly, leading to quality defects such as honeycombing and pitting, ultimately affecting the final structural strength and durability of the crash barrier. Utility Model Content

[0003] The main purpose of this utility model is to provide an adjustable concrete vibration device to solve the accessibility and applicability problems of vibration equipment in narrow, corner, and blind area structures. To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable concrete vibration device, including a control module, an extension component, an angle adjustment mechanism and a vibrating rod; The extension assembly is composed of at least one extension tube spliced ​​together sequentially through a detachable connection structure. Its first end is detachably connected to the control module, and its tail end is detachably connected to the angle adjustment mechanism. The angle adjustment mechanism is connected to the vibrating rod via a rotating joint; The rigid rope extends along the length of the extension component and connects the control module and the angle adjustment mechanism, which is used to adjust the angle of the vibrator at the proximal end via the control module.

[0004] In the preferred embodiment, the detachable connection structure of the extension component is a double-threaded interface, with matching male and female threads at both ends of each extension tube. The control module and the angle adjustment mechanism are respectively equipped with threaded structures that match the extension components.

[0005] In the preferred embodiment, the angle adjustment mechanism includes a connecting block, a rotating joint, a ratchet, and a roller chain; The connecting block is rotatably connected to the upper end of the rotating joint via a rotating shaft, and the lower end of the rotating joint is fixedly connected to the vibrating rod. One end of the rotating shaft extends out of the connecting block and is fixedly connected to the ratchet coaxially; The roller chain is partially wound around and engaged with the lower half-circle of the ratchet, and both ends of the roller chain are connected to the far end of the rigid rope.

[0006] In the preferred embodiment, the length of the roller chain is configured such that when the rigid rope pulls the roller chain, this length can drive the ratchet to rotate at a set angle, the angle range of which covers the entire adjustment angle range required by the vibrator.

[0007] In the preferred embodiment, a protective shell is provided on the outside of the angle adjustment mechanism to cover the ratchet and roller chain area; The end of the rotating shaft extending from the connecting block is rotatably connected to the side wall of the protective shell; The ends of the two rigid ropes are connected to the two ends of the roller chain, pass through the top of the protective shell, and extend to the control module; A flexible sealing membrane is also provided at the top of the protective shell where the rigid rope passes through.

[0008] In the preferred embodiment, the control module includes a base, a grip, and an adjustment dial; The adjusting disc is rotatably connected to the base via a central rotating shaft; Two fixing elements are symmetrically provided on the adjustment disc to fix the ends of the rigid ropes to the pre-tensioned state respectively; The axial part passes through the adjusting plate and is rotatably connected to the adjusting plate. Multiple locking holes are provided on the side wall of the base along the rotation path of the rotating handle. The lower end of the rotating handle is inserted into the corresponding locking hole to fix the angle of the adjustment disc.

[0009] In the preferred embodiment, the sidewall of the extension pipe is provided with a protective pipe that runs longitudinally through it along its length. When all extension tubes are spliced, adjacent protective tubes are connected to each other to protect the rigid rope.

[0010] In the preferred embodiment, a second vibrating rod and a second angle adjustment structure for driving its rotation are also provided; The second angle adjustment structure is detachably connected to the lower end of the vibrator, and its input end is connected to the far end of the second rigid rope. The control module is equipped with a second adjustment disc, and the near end of the second rigid rope is connected to the second adjustment disc to realize independent angle control of the second angle adjustment structure.

[0011] In the preferred embodiment, the second angle adjustment structure and the angle adjustment mechanism are symmetrically arranged about the longitudinal axis of the extension component; The second rigid rope and the second adjusting disc are symmetrically arranged and operate independently.

[0012] In the preferred embodiment, the corresponding extension tube sidewall is symmetrically provided with a second protective tube for threading a second protective rigid rope. A flexible protective sleeve is sealed between the end of the second protective tube of the last extension tube and the second angle adjustment structure to cover the second rigid rope segment that is not protected by the second protective tube.

[0013] This invention provides an adjustable concrete vibratory compaction device. Through the coordinated design of a modular extension component and an angle adjustment mechanism, it significantly improves construction adaptability in narrow and irregularly shaped concrete structures. The extension component adopts a multi-segment threaded splicing structure, which can flexibly adjust the length of the device according to the depth of the gap between the reinforcing bars, ensuring that the vibrator reaches blind spots that are difficult for traditional equipment to access. The angle adjustment mechanism utilizes a ratchet-roller chain drive system to achieve precise remote control through a rigid rope, enabling the vibrator to deflect at multiple angles within confined spaces. This effectively covers vibration blind spots in complex structures, thereby improving concrete density and reducing quality defects such as honeycomb and pitting.

[0014] The introduction of a protective shell and sealing design enhances the device's durability. The ratchet and roller chain areas are completely covered by the protective shell, and the flexible sealing membrane effectively prevents concrete slurry from entering, avoiding jamming or wear of transmission components. Simultaneously, the rotating connection design between the shaft end and the protective shell improves transmission stability and ensures accurate angle adjustment. After the device is withdrawn, the smooth surface of the extension tube facilitates cleaning, reducing maintenance costs caused by concrete residue.

[0015] The control module employs a mechanical structure with an adjustment disc and locking holes, allowing operators to adjust and fix the angle with one hand. The added second vibrator and independent control system, through symmetrically arranged rigid ropes and protective tubes, simultaneously cover a larger vibration area in a single operation, making it particularly suitable for multi-arc curved structures and significantly improving construction efficiency. The overall structure balances lightweight and rigidity, and its modular design facilitates transportation and rapid on-site assembly, making it suitable for high-quality concrete pouring requirements in scenarios with dense reinforcement, such as bridge crash barriers.

Detailed Implementation

[0018] Example 1 like Figure 1-7 As shown, an adjustable concrete vibrating device includes a control module 1, an extension component 2, an angle adjustment mechanism 3, and a vibrating rod 4. The extension component 2 is formed by sequentially splicing at least one extension tube 201 through a detachable connection structure. Its first end is detachably connected to the control module 1, and its tail end is detachably connected to the angle adjustment mechanism 3. Angle adjustment mechanism 3 is connected to vibrating rod 4 via a rotating joint; The rigid rope 5 extends along the length of the extension component 2 and connects the control module 1 and the angle adjustment mechanism 3, and is used to adjust the angle of the vibrator 4 at the proximal end via the control module 1.

[0019] This application solves the problem of blind spots in the vibration of irregularly shaped poured concrete through modular design. The operator holds the control module 1 and splices the extension component 2 to the required length according to the depth of the gap between the reinforcing bars. By pulling the rigid rope 5, the operator drives the angle adjustment mechanism 3 to make the vibrator 4 accurately deflect at the corner, ensuring that the vibrator 4 can reach narrow areas that traditional vibration equipment cannot cover.

[0020] In the preferred embodiment, the detachable connection structure of the extension component 2 is a double-threaded interface, and each end of the extension tube 201 is provided with a matching male thread 2011 and a female thread 2012. The control module 1 and the angle adjustment mechanism 3 are respectively provided with threaded structures that match the extension component 2.

[0021] In the preferred embodiment, the angle adjustment mechanism 3 includes a connecting block 301, a rotating joint 302, a ratchet 303, and a roller chain 304; The connecting block 301 is rotatably connected to the upper end of the rotating section 302 via the rotating shaft 3021, and the lower end of the rotating section 302 is fixedly connected to the vibrating rod 4. One end of the rotating shaft 3021 extends out of the connecting block 301 and is coaxially and fixedly connected to the ratchet 303; The roller chain 304 is partially wound around and engaged with the lower half-circumference of the ratchet 303, and both ends of the roller chain 304 are connected to the far end of the rigid rope 5.

[0022] The modular splicing structure allows the device's depth to be freely spliced ​​and set according to requirements, and the control module 1 and the angle adjustment mechanism 3 are adaptively connected according to the splicing length.

[0023] In the preferred embodiment, the length of the roller chain 304 is configured such that when the rigid rope 5 pulls the roller chain 304, this length can drive the ratchet 303 to rotate at a set angle, the angle range of which covers the entire adjustment angle range required by the vibrator 4.

[0024] The rotary joint and ratchet drive mechanism enables the vibrator 4 to be positioned at multiple angles within a confined space. Its compact structure, with the roller chain 304 and rigid rope 5 positioned close to the contour of the extension component 2, reduces the space occupied by the transmission mechanism. The roller chain 304 only requires the length corresponding to the desired adjustment angle, which reduces the overall cost of the device. The simpler rigid rope 5 can be used in areas where meshing is not required. Furthermore, the rigid rope 5 exhibits less precision and deformation during transmission than the roller chain 304, ensuring accurate adjustment of the transmission angle.

[0025] In the preferred embodiment, the angle adjustment mechanism 3 is provided with a protective shell 6 to cover the area of ​​the ratchet 303 and the roller chain 304; The end of the rotating shaft 3021 extending out of the connecting block 301 is rotatably connected to the side wall of the protective shell 6; The ends of the two rigid ropes 5 are respectively connected to the two ends of the roller chain 304, and extend to the control module 1 after passing through the top of the protective shell 6; The rigid rope 5 passes through the top of the protective shell 6 and is also equipped with a flexible sealing membrane 601.

[0026] Since the transmission components and angle adjustment components are both deeply embedded in the concrete pouring area, the lateral pressure of the concrete on the device causes some concrete to penetrate into the device, causing jamming and wear on the meshing of the ratchet 303 and roller chain 304. Therefore, a protective shell 6 structure is added to protect the important rotating components and transmission structure. At the same time, after the device is removed after vibration, concrete tends to adhere to it. The surface of the extension component 2 is flat and smooth and easy to clean. The ratchet 303 and roller chain 304 have a lot of detailed structures, which can easily cause concrete to accumulate in the structural gaps. After solidification, it will affect the next use of the device. Therefore, important transmission parts need to be sealed and protected.

[0027] The connecting block 301 extends from the coaxial connection between the rotating shaft 3021 and the ratchet 303, which is equivalent to a cantilever end. However, due to the requirement of transmission accuracy, it receives a large tension traction force from the rigid rope 5. Therefore, its end is placed on the protective shell 6 to enhance the rotational structural stability of the rotating shaft 3021.

[0028] In the preferred embodiment, the control module 1 includes a base 101, a handle 102, and an adjustment dial 7; The adjusting disc 7 is rotatably connected to the base 101 via the central rotating shaft 701; Two fixing elements 702 are symmetrically provided on the adjusting plate 7, which are used to fix the ends of the rigid rope 5 to the pre-tightened state respectively; Rotate 703 axially through the adjusting plate 7 and rotate to connect with the adjusting plate 7; Multiple locking holes 103 are provided on the side wall of the base 101 along the rotation path of the rotating handle 703. The lower end of the rotating handle 703 is inserted into the corresponding locking hole 103 to fix the angle of the adjusting plate 7.

[0029] In the preferred embodiment, the side wall of the extension pipe 201 is provided with a protective pipe 202 that runs longitudinally through it along its length. When all extension tubes 201 are spliced, adjacent protective tubes 202 are connected to each other to protect the rigid rope 5.

[0030] Specifically, when using the device, the operator first connects a section of extension tube 201 to the angle adjustment mechanism 3 and the vibrator 4 via thread. The subsequent extension tube 201 stages can be spliced ​​while being extended into the concrete, or pre-splitting according to the required depth. After the extension component 2 is assembled to the required length, its top end is a certain distance above the concrete surface. Then, the top end of the extension component 2 is threaded to the control module 1. The electrical control component of the vibrator 4 is extended to the top control module 1 through the hollow extension tube 201 component to control the opening and closing of the vibrator 4.

[0031] Two rigid ropes 5 are set to the required length and extend to the height of the control module 1. Their ends are symmetrically fixed and connected to the adjustment plate 7 fixed at the initial angle, and both ends are tensioned to the same degree. At this time, the meshing section of the roller chain 304 and the ratchet 303 is located in the middle of the roller chain 304, and the ratchet 303 is in the neutral position. That is, the central axis of the vibrator 4 is parallel to the extension component 2, that is, the device is generally vertical.

[0032] When angle adjustment is required, pull out the rotating handle 703 fixed at the initial angle, drive the ratchet 303 to rotate to the desired angle. A corresponding angle scale can be set on the side wall of the base 101, and the roller chain 304 moves accordingly, driving the ratchet 303 to rotate, thereby causing the angle of the vibrator 4 to shift from the central axis of the extension component 2. After adjustment, insert the lower end of the rotating handle 703 into the locking hole 103 of the corresponding angle to lock the current angle.

[0033] Example 2 Further explanation in conjunction with Example 1, such as Figure 8 The structure shown also includes a second vibrating rod 8 and a second angle adjustment structure 9 for driving its rotation; The second angle adjustment structure 9 is detachably connected to the lower end of the vibrator 4, and its input end is connected to the far end of the second rigid rope 10. The control module 1 is equipped with a second adjustment disc 11, and the proximal end of the second rigid rope 10 is connected to the second adjustment disc 11 to realize independent angle control of the second angle adjustment structure 9.

[0034] In the preferred embodiment, the second angle adjustment structure 9 and the angle adjustment mechanism 3 are symmetrically arranged about the longitudinal axis of the extension component 2; The second rigid rope 10 and the rigid rope 5, and the second adjusting disc 11 and the adjusting disc 7 are symmetrically arranged and operate independently.

[0035] In the preferred embodiment, the sidewall of the corresponding extension tube 201 is symmetrically provided with a second protective tube 203 for threading the second protective rigid rope 10. A flexible protective sleeve 12 is sealed between the end of the second protective tube 203 of the last extension tube 201 and the second angle adjustment structure 9, for covering the second rigid rope 10 segment that is not protected by the second protective tube 203.

[0036] This embodiment adds a second vibrating rod 8 to the first embodiment. The angle adjustment unit and drive component structure are the same as the first set of vibrating rods 4, but the setting position needs to be different to avoid interference of the transmission components. In this embodiment, it is preferable that the two sets of transmissions are set on both sides of the extension component 2 to balance the force on both sides of the device.

[0037] The second set of vibrating components expands the overall vibration range of the device, with an increased angle adjustment range, and can adapt to different curvatures through two rotation stages.

[0038] Since the second rigid rope 10 has no extension tube 201 on the side of the first set of vibrating rods 4, it is protected by a flexible protective sleeve structure.

[0039] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
