Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a dam concrete vibrator. Background Technology

[0002] In the construction of water conservancy projects such as dams, concrete is the main building material, and its quality is directly related to the safety and durability of the entire project. Concrete vibration is one of the key steps in the concrete construction process. Vibration can effectively remove air bubbles and excess water from the concrete, increase the density and uniformity of the concrete, and thus improve the strength and durability of the concrete.

[0003] Traditional dam concrete vibration operations mainly rely on manual hand-held vibrators. This method is inefficient and cannot meet the needs of large-scale construction. In addition, manual vibration also poses safety hazards, as operators need to perform high-intensity work on the construction site for a long time, which can easily lead to fatigue and safety accidents. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that rely on manual hand-held vibrators, which are inefficient and cannot meet the needs of large-scale construction. Furthermore, manual vibration poses safety hazards, as operators need to perform high-intensity work on the construction site for extended periods, which can easily lead to fatigue and safety accidents. Therefore, this invention proposes a dam concrete vibrator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dam concrete vibrator includes four vibrators for vibrating concrete. The excavator's bucket has an upper channel steel and a lower channel steel fixedly installed on its outer wall, and all four vibrators are installed on one side of the lower channel steel.

[0007] Two frequency converters are used to control the vibration frequency of the vibrator. The excavator is fixedly equipped with a mounting plate, and both frequency converters are fixedly mounted on the top of the mounting plate. The frequency converters are electrically connected to the corresponding vibrators.

[0008] The installation mechanism is used to install the vibrator to one side of the lower channel steel. The installation mechanism is set on one side of the lower channel steel and includes four fixing plates. The four fixing plates are all fixedly set on one side of the lower channel steel. The side of the fixing plate is provided with a slot, and the slot is into which a plug plate is inserted. The four vibrators are respectively fixedly set with the four plug plates.

[0009] In one possible design, the mounting mechanism further includes bolts at both ends of one side of the fixing plate, the bolts having threads that penetrate the fixing plate, and through holes on both sides of the insert plate, with the bolts passing through the corresponding through holes.

[0010] In one possible design, the installation mechanism further includes a fixing member at one end of the bolt. Both ends of the fixing plate away from the vibrator are fixedly provided with T-shaped rings, and the bolt passes through the corresponding T-shaped rings. The fixing member includes a first through rod and a second through rod. The outer wall of the bolt has a through hole, and one end of the first through rod is inserted into the inside of the through hole. The ends of the first and second through rods away from each other are fixedly provided with limit clamps, and the two limit clamps cooperate with the outer wall of the adjacent T-shaped ring.

[0011] In one possible design, the fixing member further includes an inner rod, which is rotatably disposed inside the second through rod. One end of the first through rod has a circular groove, and one end of the second through rod is located inside the circular groove. The first through rod has a circular cavity inside, and the same semi-circular connecting hole is formed between the circular cavity and the circular groove. A connecting rod is fixedly disposed at one end of the inner rod, and a semi-circular block is fixedly disposed at one end of the connecting rod. The semi-circular block cooperates with the circular cavity and the semi-circular connecting hole.

[0012] In one possible design, a limiting ring is fixedly sleeved on the outer wall of the inner rod, the second through rod is rotatably sleeved on the outer wall of the limiting ring, an annular groove is formed on the inner wall of the second through rod, a fixing ring is fixedly sleeved on the outer wall of the inner rod and the fixing ring is located inside the annular groove, and a torsion spring is sleeved on the outer wall of the inner rod, with the two ends of the torsion spring respectively fixedly set at the bottom of the fixing ring and the bottom inner wall of the annular groove.

[0013] In one possible design, a torsion block is fixedly provided at one end of the inner rod.

[0014] In one possible design, a plurality of clips are provided on one side of the upper channel steel, and the clips cooperate with the wire harness of the corresponding vibrator.

[0015] In this application, during actual use, the insert plate equipped with the vibrator is inserted into the slot. Then, bolts are used to connect the fixing plate and the insert plate together for initial fixation. Next, one end of the first through rod is passed through the through hole, and the limiting clamp is locked onto the outer wall of the T-shaped ring. Then, one end of the second through rod is inserted into the circular groove. When inserting the second through rod, the torsion block is rotated first. The torsion block drives the inner rod to rotate, which in turn drives the connecting rod to rotate. The connecting rod then drives the semi-circular block to rotate, allowing the semi-circular block to be inserted into the circular cavity through the semi-circular connecting hole. Afterward, the inner rod is reset by the torsion spring, thereby resetting the semi-circular block and locking one section of it into the circular cavity, completing the connection and fixation between the first and second through rods. At this time, the limiting clamp at one end of the second through rod is also locked onto the outer wall of the T-shaped ring. Thus, by clamping the bolts onto the outer wall of the T-shaped ring with the two limiting clamps, the bolts are limited and cannot be displaced, thereby preventing the bolts from loosening due to vibration from the vibrator.

[0016] In this utility model, a dam concrete vibrator is installed on the bucket of an excavator, which can replace manual operation of the vibrator and allow multiple vibrators to be operated simultaneously for compaction work. This improves efficiency and safety.

[0017] In this utility model, the dam concrete vibrator can be quickly installed through the installation mechanism, which facilitates actual use and subsequent disassembly and maintenance, and can also avoid the phenomenon of bolt loosening due to vibration, thus ensuring stability.

[0018] In this invention, the vibrator is moved by an excavator during use, thereby achieving both high density and uniformity of concrete while addressing the issues of low efficiency and safety associated with manual hand operation. Furthermore, the vibrator is easy to install and disassemble, facilitating practical operation and preventing instability due to vibration. Attached Figure Description

[0028] An installation mechanism is provided on one side of the lower channel steel 3.

[0029] This application can be used in the field of engineering construction, or in other fields applicable to this application.

[0030] Example 2

[0031] refer to Figure 2 An improvement based on Example 1: A dam concrete vibrator, which is applied to the field of engineering construction, includes four fixing plates 8. The four fixing plates 8 are fixedly installed on one side of the lower channel steel 3 by welding. The side of the fixing plate 8 is provided with a slot 7. The slot 7 is inserted with a plate 10. The four vibrators 4 are respectively fixedly installed on the side of the four plates 10.

[0032] The mounting mechanism also includes bolts 9 at both ends of one side of the fixing plate 8. The bolts 9 are threaded through the fixing plate 8. Both sides of the insert plate 10 are provided with through holes 11, and the bolts 9 pass through the corresponding through holes 11. The bolts 9 are used to connect and fix the insert plate 10 and the fixing plate 8.

[0033] Reference Figure 3-4The installation mechanism also includes a fixing component at one end of the bolt 9. T-shaped rings 15 are fixedly installed at both ends of the fixing plate 8 on the side away from the vibrator 4, and the bolt 9 passes through the corresponding T-shaped rings 15. The fixing component includes a first through rod 13 and a second through rod 14. A through hole 16 is opened on the outer wall of the bolt 9, and one end of the first through rod 13 is inserted into the interior of the through hole 16. The ends of the first through rod 13 and the second through rod 14 that are far apart are fixedly installed with limiting clamps 12 by welding. The two limiting clamps 12 cooperate with the outer wall of the adjacent T-shaped rings 15. After the two through rods are assembled by passing through the through hole 16, the two limiting clamps 12 will be clamped on the outer wall of the T-shaped rings 15, thereby limiting the bolt 9 so that it cannot move, avoiding loosening due to vibration, and ensuring stability.

[0034] Reference Figure 4-5 The fastener also includes an inner rod 19, which is rotatably disposed inside the second through rod 14. One end of the first through rod 13 is provided with a circular groove 22, and one end of the second through rod 14 is located inside the circular groove 22. A circular cavity 20 is provided inside the first through rod 13. The same semi-circular connecting hole 21 is provided between the circular cavity 20 and the circular groove 22. A connecting rod 18 is fixedly disposed at one end of the inner rod 19, and a semi-circular block 17 is fixedly disposed at one end of the connecting rod 18. The semi-circular block 17 cooperates with the circular cavity 20 and the semi-circular connecting hole 21.

[0035] A limiting ring 23 is fixedly sleeved on the outer wall of the inner rod 19. The second through rod 14 is rotatably sleeved on the outer wall of the limiting ring 23. An annular groove 26 is opened on the inner wall of the second through rod 14. A fixing ring 25 is fixedly sleeved on the outer wall of the inner rod 19, and the fixing ring 25 is located inside the annular groove 26. A torsion spring 27 is sleeved on the outer wall of the inner rod 19, and the two ends of the torsion spring 27 are respectively fixedly set at the bottom of the fixing ring 25 and the bottom inner wall of the annular groove 26. The torsion spring 27 is used to reset the inner rod 19.

[0036] Specifically, the insert plate 10 with the vibrator 4 installed is inserted into the slot 7. Then, the fixing plate 8 and the insert plate 10 are connected together with bolts 9 to achieve initial fixation. Then, one end of the first through rod 13 is passed through the through hole 16, and the limiting clamp 12 is locked onto the outer wall of the T-shaped ring 15. Then, one end of the second through rod 14 is inserted into the circular groove 22. When inserting the second through rod 14, first rotate the torsion block 24. The torsion block 24 drives the inner rod 19 to rotate, the inner rod 19 drives the connecting rod 18 to rotate, and the connecting rod 18 drives the semicircular block 17 to rotate, so that the semicircular block 17 can pass through the semicircular connecting hole 21. Inserted into the cavity 20, the inner rod 19 is then reset by the torsion spring 27, which in turn drives the semicircular block 17 to reset, causing one section of the semicircular block 17 to be locked inside the cavity 20, completing the connection and fixation between the first through rod 13 and the second through rod 14. At this time, the limiting clamp 12 at one end of the second through rod 14 will also be locked on the outer wall of the T-shaped ring 15. Thus, the two limiting clamps 12 are clamped on the outer wall of the T-shaped ring 15, and one end of the limiting clamp 12 will abut against the fixing plate 8, limiting the bolt 9 so that it cannot move, thereby avoiding the problem of the bolt 9 loosening due to the vibration of the vibrator 4.

[0037] A torsion block 24 is fixedly installed at one end of the inner rod 19. The torsion block 24 is designed to facilitate the operator to rotate the inner rod 19, so that the inner rod 19 drives the semi-circular block 17 to move.

[0038] Multiple clips are provided on one side of the upper channel steel 2. The clips cooperate with the wire harness of the corresponding vibrator 4. The clips are used to limit and fix the wire harness of the vibrator 4 to prevent the wire harness of the vibrator 4 from becoming tangled.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the excavator 1, vibrator 4 and frequency converter 6 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
