Description

Technical Field

[0001] This utility model belongs to the field of concrete vibration technology, specifically relating to a concrete vibration device for highway construction. Background Technology

[0002] In modern highway construction, concrete vibration is a crucial process for ensuring pavement quality. The performance and reliability of the construction equipment directly affect the overall project quality and construction efficiency. However, existing concrete vibration devices for highway construction face a series of technical challenges that urgently need to be addressed in practical applications. To meet the engineering needs of large-area concrete vibration, the industry has developed a multi-vibrator collaborative operation technical solution. This involves a structural design that simultaneously installs multiple vibrators on a movable frame to achieve uniform vibration treatment of large areas of concrete. This design has indeed achieved certain results in improving construction efficiency, but challenges remain regarding the installation of the vibrators and... The disassembly process, however, revealed significant technical deficiencies. Specifically, traditional vibratory compaction devices often use conventional mechanical connections such as bolts to connect the vibrator to the movable frame. In practice, these connections typically require operators to use various specialized tools such as wrenches and screwdrivers to tighten or loosen them. The entire process involves numerous steps and complex operations, consuming a great deal of time and effort to complete the disassembly and assembly of a single vibrator. In large-scale highway construction projects, frequent disassembly and assembly of vibrators is a common requirement, such as during equipment maintenance, troubleshooting, or changes in construction areas. This cumbersome disassembly and assembly process severely restricts the construction progress and reduces work efficiency.

[0003] To address the aforementioned technical issues of inconvenient assembly and disassembly of vibrators, some improved designs have indeed emerged in the industry. These designs have simplified the assembly and disassembly process to some extent, reduced reliance on specialized tools, and brought certain conveniences to construction sites. However, while solving the problem of ease of assembly and disassembly, these improved designs have introduced new technical risks, mainly manifested in deficiencies in the stability and reliability of the fixed structure. Specifically, these quick-connect structures are relatively simple. During concrete vibration, the vibrator generates high-frequency, continuous, and intense vibrations. These vibrations not only act on the concrete itself but are also transmitted to the entire mobile frame structure through mechanical connections. Under such harsh working conditions, simple quick-connect designs become problematic. The connection structure is prone to loosening due to resonance, which may cause the fixed parts to gradually shift. More seriously, when the vibration accumulates to a certain level, it may trigger the connection mechanism to unlock unexpectedly, causing the vibrator to suddenly detach from the movable frame while running at high speed. This will not only cause equipment damage and engineering quality problems, but may also lead to serious safety accidents, threatening the personal safety of on-site construction personnel. This technical defect of insufficient structural stability makes this type of improved equipment face serious reliability and safety risks in practical applications. It cannot meet the strict requirements of highway construction for long-term stable operation of equipment, which limits the promotion and application of related technologies and brings potential economic losses and safety hazards to highway construction companies.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a concrete vibration device for highway construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A concrete vibrating device for highway construction includes a movable frame. A vibrating motor is detachably mounted on the movable frame. A fixing device is provided on the vibrating motor. The fixing device includes a fixing sleeve, a fixing rod, a fixing groove, an unlocking sleeve, a fixing frame, an unlocking groove, and an unlocking plate. The fixing sleeve is detachably mounted on the outside of the fixing rod. The fixing groove is located on the outside of the fixing rod. The unlocking sleeve is rotatably mounted on the outside of the fixing sleeve. Both the unlocking groove and the unlocking plate are variable-diameter structures. The unlocking groove is located on the inside of the unlocking sleeve, and the outer wall of the unlocking plate is in close contact with the inner wall of the unlocking groove. The fixing frame is fixedly connected to one side of the unlocking plate, with one end of the fixing frame inserted into the fixing groove. A positioning mechanism is provided on the outside of the fixing sleeve. The positioning mechanism includes a return spring, a return block, a movable hole, and a movable groove. The system comprises a support rod, a support plate, a movable frame, a movable sleeve, a movable plate, a connecting block, a movable rod, a movable plate, and a movable groove. The fixed rod is fixedly installed inside the movable frame. The two ends of the return spring are respectively connected to the return block and the connecting block. The return block is fixedly installed on one side of the movable plate. The movable hole is opened at one end of the movable groove, and the movable groove is opened on the movable plate. The support rod is fixedly connected to one side of the movable sleeve. Two support plates are fixedly installed on the support rod. The movable frame is fixedly installed on one side of the unlocking sleeve. The movable sleeve is slidably installed on the outside of the fixed sleeve. The movable plate is rotatably installed on the outside of the fixed sleeve. The connecting block is fixedly installed on the outside of the fixed sleeve. The movable rod is slidably installed in the movable frame. The movable plate is fixedly installed at one end of the movable rod. The movable groove is opened on the outside of the fixed sleeve.

[0007] Furthermore, the output end of the vibratory motor is connected to a flexible hose, and the other end of the hose is connected to a vibratory rod. This flexible connection design allows the vibration energy to be efficiently transmitted to the vibratory rod, and allows the vibratory rod to flexibly reach all areas of the concrete, ensuring the uniform vibration quality of the concrete and greatly improving the vibration effect and construction efficiency.

[0008] Furthermore, the bottom of the movable frame is equipped with a rotatable roller, and the outside of the movable frame is detachably equipped with a handle. This convenient design greatly improves the flexibility and operability of the equipment. The rollers allow the entire vibrating device to be easily moved on the construction site, while the detachable handle facilitates the pushing and pulling control of the device.

[0009] Furthermore, a return rod is connected to one end of the return block, and a return hole is opened in the connecting block. One end of the return rod slides through the return hole. This guide structure design provides a stable motion trajectory for the return spring and prevents deviation due to external force interference.

[0010] Furthermore, a spring is movably sleeved on the outer side of the support rod. One end of the spring is connected to the movable sleeve, and the other end of the spring is in contact with the movable plate. This elastic support design provides the movable sleeve with a power source for active reset, ensuring that when the operation is released, the movable sleeve can automatically return to its initial position under the push of the spring.

[0011] Furthermore, a guide block is fixedly provided on the inner side of the movable sleeve, and a guide groove is provided on the outer side of the fixed sleeve. The guide block slides in the guide groove. This guiding and limiting design provides a precise movement trajectory for the movable sleeve, ensuring that the movable sleeve can only move in a straight line along the direction of the guide groove. This effectively prevents the movable sleeve from deflecting or rotating during operation. The precise cooperation between the guide block and the guide groove also reduces the shaking and swaying of the movable sleeve, improving the accuracy and stability of the operation.

[0012] Furthermore, an unlocking spring is movably sleeved on the outer side of the fixed frame. The two ends of the unlocking spring are connected to the inner wall of the unlocking plate and the outer wall of the fixed sleeve, respectively, to ensure that the outer wall of the unlocking plate always maintains close contact with the inner wall of the variable diameter unlocking groove. No matter what angle the unlocking sleeve is at, the unlocking spring can adapt to the variable diameter structure of the unlocking groove and push the unlocking plate to make corresponding radial movements.

[0013] Furthermore, a movable spring is movably sleeved on the outer side of the movable rod. The two ends of the movable spring are connected to the movable plate and the movable frame, respectively. This automatic reset design provides a reliable return guarantee for the movable rod, ensuring that after the unlocking operation is completed, the movable rod can automatically return to the original locked position under the tension of the movable spring, without the need for the operator to perform additional reset operations.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The fixing device of this utility model effectively solves the technical problem of cumbersome disassembly and assembly of the vibrating motor in the concrete vibrating device for modern highway construction through scientific and reasonable structural design. The device is ingeniously combined with components such as fixing sleeve, fixing rod, fixing groove, unlocking sleeve, fixing frame, unlocking groove and unlocking plate to form a complete quick disassembly and assembly system for the vibrating motor. Its core working principle is to use the rotation of the unlocking sleeve to trigger a chain reaction: This variable diameter structure design allows the operator to easily and accurately disassemble the vibrating motor by simply rotating the unlocking sleeve without the need for special tools such as wrenches and screwdrivers, which greatly improves the ease of operation. The detachable design of the fixing rod and the fixing sleeve allows the vibrating motor to be quickly installed on the movable frame. The unlocking spring connects the unlocking plate and the outer wall of the fixing sleeve, providing appropriate elastic support for the unlocking plate, so that the unlocking plate can be tightly attached to the inner wall of the unlocking groove, ensuring the smooth and reliable unlocking action.

[0015] (2) As a key supporting system for the fixing device, the positioning mechanism of this utility model effectively solves the core problem of insufficient fixing stability of the vibratory motor in the prior art through precise mechanical structure design. The mechanism is composed of components such as return spring, return block, movable hole, movable groove, support rod, support plate, movable frame, movable sleeve, movable plate, connecting block, movable rod, movable plate and movable groove, forming a complete multi-layer anti-loosening system. Its working principle is to control the position of the support rod and support plate by rotating the movable plate. This design enables the inner wall of the movable sleeve to effectively limit the outer wall of the movable plate, preventing the movable plate from moving outward, thereby locking the movable rod and ensuring that the movable frame and unlocking sleeve will not rotate unexpectedly, providing a stable and reliable position for the vibratory motor. The fixed support, the guide block on the inner side of the moving sleeve and the guide groove on the outer side of the fixed sleeve cooperate to provide a precise movement trajectory for the moving sleeve, preventing the moving sleeve from deviating during operation. This multi-locking mechanism effectively copes with the high-frequency and strong vibrations generated during concrete vibration. Even under harsh working conditions, it can maintain the stability and reliability of the structure and prevent the risk of accidental unlocking of the connection mechanism due to vibration accumulation. Overall, the positioning mechanism provides reliable locking protection for the fixing device through a scientific and reasonable mechanical structure design, solves the technical problem of insufficient stability of traditional vibration devices, significantly improves the reliability and service life of concrete vibration devices in highway construction, and provides strong support for the safe and efficient operation of highway construction.

The fixed rod 4 is fixedly installed inside the movable frame 1. The two ends of the return spring 10 are connected to the return block 11 and the connecting block 19, respectively. The return block 11 is fixedly installed on one side of the movable plate 18. The movable hole 12 is opened at one end of the movable groove 13. The movable groove 13 is opened on the movable plate 18. The support rod 14 is fixedly connected to one side of the moving sleeve 17. Two support plates 15 are fixedly installed on the support rod 14. The moving frame 16 is fixedly installed on one side of the unlocking sleeve 6.

The connecting block 19 is fixedly installed on the outside of the fixed sleeve 3. The moving rod 20 is slidably installed in the moving frame 16. The moving plate 21 is fixedly installed at one end of the moving rod 20. The moving groove 22 is opened on the outside of the fixed sleeve 3.

[0020] The output end of the vibratory motor 2 is connected to a flexible hose 23, and the other end of the flexible hose 23 is connected to a vibratory rod 24.

[0021] The bottom of the movable frame 1 is equipped with a rotating roller 25, and the outside of the movable frame 1 is detachably equipped with a handle 26.

[0022] In this embodiment, when the device is needed, the movable frame 1 can be moved by the handle 26, so that the movable frame 1 can be moved by the roller 25 set at the bottom. After moving to the appropriate position, the vibrating rod 24 is inserted into the concrete, and then multiple vibrating motors 2 are turned on, so that the vibrating motors 2 transmit vibration to the vibrating rod 24 through the hose 23 to achieve the vibration of the concrete.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: a return rod 27 is connected to one end of the return block 11, and a return hole 28 is opened in the connecting block 19, and one end of the return rod 27 slides through the return hole 28.

[0024] A spring 29 is movably sleeved on the outer side of the support rod 14. One end of the spring 29 is connected to the movable sleeve 17, and the other end of the spring 29 is connected to the movable plate 18 in contact.

[0025] A guide block 30 is fixedly provided on the inner side of the movable sleeve 17, and a guide groove 31 is provided on the outer side of the fixed sleeve 3, with the guide block 30 sliding in the guide groove 31.

[0026] An unlocking spring 32 is movably sleeved on the outside of the fixed frame 7. The two ends of the unlocking spring 32 are connected to the inner wall of the unlocking plate 9 and the outer wall of the fixed sleeve 3, respectively.

[0027] A movable spring 33 is movably sleeved on the outside of the movable rod 20, and the two ends of the movable spring 33 are connected to the movable plate 21 and the movable frame 16 respectively.

[0028] When the vibratory motor 2 needs to be removed, first rotate the movable plate 18 forward. The movable plate 18 will drive the movable hole 12 and the movable groove 13 to rotate forward, and the movable plate 18 will also drive the return block 11 on one side to rotate forward. Then the return block 11 will drive the return rod 27 on one side to rotate forward along the return hole 28, and the return block 11 will cooperate with the connecting block 19 to compress the return spring 10. When the return spring 10 is compressed to its limit, the movable hole 12 will just rotate to a position concentric with the support plate 15. Then push the moving sleeve 17. The moving sleeve 17 will drive the inner guide block 30 to slide along the guide groove 31, and the moving sleeve 17 will drive the support rod 14 and the support plate 15 to gradually pass through the movable hole 12. At the same time, the moving sleeve 17 will cooperate with the movable plate 18 to compress the support spring 29. When the support spring 29 is compressed to its limit, a support plate 15 near the movable sleeve 17 passes through the movable hole 12 and moves to the other side of the movable plate 18. Then the movable plate 18 is released, and the return spring 10 pushes the return block 11 to rotate in the opposite direction. Then the return block 11 drives the return rod 27 to rotate in the opposite direction along the return hole 28. The return block 11 drives the movable hole 12 and the movable groove 13 to rotate in the opposite direction through the movable plate 18. At this time, the support rod 14 will be in the movable groove 13. Then the support rod 14, together with the support plate 15 near the movable sleeve 17, limits the movable sleeve 17 to one side of the movable plate 18, so that the movable sleeve 17 no longer limits the outside of the movable plate 21. Then the unlocking sleeve 6 is rotated in the forward direction. The unlocking sleeve 6 will drive the movable frame 16 to rotate in the forward direction. Then the movable frame 16 will drive the movable plate 21 to rotate in the forward direction. The moving rod 20, the moving plate 21, and the moving spring 33 rotate forward. Then, the inner wall of the moving groove 22 presses against one end of the moving rod 20. Due to the rounded corner design at the edge of the inner wall of the moving groove 22 and the rounded corner treatment at one end of the moving rod 20, one end of the moving rod 20 moves out of the moving groove 22. The other end of the moving rod 20 drives the moving plate 21 to slide outward. Simultaneously, the unlocking sleeve 6 drives the inner variable-diameter unlocking groove 8 to rotate forward. Then, the unlocking spring 32 pushes the unlocking plate 9 to move outward, ensuring that the outer wall of the unlocking plate 9 remains in close contact with the inner wall of the unlocking groove 8. The unlocking plate 9 then drives one side of the fixing bracket 7 to slide outward, causing the fixing bracket 7 to be removed from the fixing groove 5. Then, the fixing sleeve 3 is pulled upward to remove it. Then refer to... Following the steps described above, remove the other fixing sleeves 3, then lift the vibrating motor 2 upwards to remove it. When it is necessary to install the vibrating motor 2, first place the vibrating motor 2 inside the movable frame 1, ensuring that the corresponding fixing rod 4 on the inside of the movable frame 1 passes through the pre-drilled mounting hole at the bottom of the vibrating motor 2. Then, fit the fixing sleeve 3 onto the outside of the fixing rod 4 from the top. Next, rotate the unlocking sleeve 6 in the opposite direction, causing the unlocking sleeve 6 to drive the moving rod 20, moving plate 21, and moving spring 33 to rotate in the opposite direction via the moving frame 16. The unlocking sleeve 6 also causes the inner unlocking groove 8 to rotate in the opposite direction. Then, the inner wall of the unlocking groove 8 presses against the outer wall of the unlocking plate 9, causing the unlocking plate 9 to move inwards. Finally, the unlocking plate 9, in conjunction with the outer wall of the fixing sleeve 3, presses against the unlocking spring 32.Furthermore, the unlocking plate 9 will cause the fixing bracket 7 to slide inward, so that one end of the fixing bracket 7 is re-engaged into the fixing groove 5. At this time, the moving bracket 16 will move the moving rod 20 to the position corresponding to the original moving groove 22. Then, the moving spring 33 will reset and pull the moving plate 21 to slide inward. Then, the moving plate 21 will drive the moving rod 20 to slide inward and reset, so that one end of the moving rod 20 is re-inserted into the original moving groove 22. Then, the movable plate 18 will be rotated forward again, and the movable plate 18 will drive... The movable hole 12 and the movable groove 13 rotate in the forward direction, and the movable plate 18 will drive the return block 11 on one side to rotate in the forward direction again. Then, the return block 11 will drive the return rod 27 to rotate in the forward direction along the return hole 28 again, and the return block 11, together with the connecting block 19, will press the return spring 10 again. When the movable hole 12 rotates to the position concentric with the support plate 15 again, the support spring 29 resets and pushes the movable sleeve 17 to drive the guide block 30 to slide and reset along the guide groove 31. Then, the movable sleeve 17 drives the two supports through the support rod 14. Plate 15 slides back to its original position. When support spring 29 is fully reset, support plate 15 at the top of support rod 14 moves back to the original side of movable plate 18. Then, movable plate 18 is released again, and return spring 10 pushes return block 11 to rotate and reset. Then, return block 11 drives return rod 27 to rotate and reset along return hole 28. Then, return block 11 drives movable hole 12 and movable slot 13 to rotate and reset to a position that does not correspond to support rod 14 and support plate 15 through movable plate 18. Then, support rod 1... 4. The top support plate 15 supports the movable sleeve 17 to one side of the movable plate 18. The guide block 30 and guide groove 31 limit the movement of the movable sleeve 17, preventing it from moving. The inner wall of the movable sleeve 17 then limits the outer wall of the movable plate 21, preventing the movable plate 21 and the moving rod 20 from moving the cabinet outwards. Finally, the moving rod 20, in conjunction with the moving groove 22, limits the movement of the frame 16, preventing the frame 16 and the unlocking sleeve 6 from rotating accidentally, thus ensuring the stability of the vibrating motor 2 installation.
