Description

Technical Field

[0001] The invention relates to the field of engineering machinery, and in particular to an insertable vibrating rod with adjustable diameter and a construction method. Background Art

[0002] When pouring components with concrete mixed by a concrete mixer, bubbles must be removed. Use a vibrating rod to vibrate the concrete to make it dense and combine, eliminate honeycombed concrete and other phenomena, so as to improve the strength of the concrete and ensure the quality of concrete components. During the construction of the bridge deck, after pouring the concrete, due to the dense steel bars on the bridge deck and the small gaps between the steel bars, the traditional vibrating rod cannot be inserted for tamping, making it difficult to vibrate the concrete; at the same time, the dense areas of steel bars are most likely to form gaps, and strong vibration is required to make the concrete dense, which brings great difficulties to the construction. In the densely reinforced area, the traditional vibration method can be used:

[0003] 1. Use the method of replacing the small diameter inserted vibrating rod. The disadvantage is that the vibrating rod needs to be replaced constantly, which brings trouble to the construction, slows the construction speed and has low construction efficiency.

[0004] 2. Reserve the hole in advance, and drive a steel pipe with a diameter slightly larger than the vibrating rod into the gap between the steel bars before pouring concrete, and remove it after pouring is completed. Disadvantages: difficult construction.

[0005] 3. The slump requirement of the concrete in the steel-dense area is larger than the general one. The disadvantages are: poor operability, which may cause concrete segregation and excessive floating slurry.

[0006] The above three methods all have various problems, such as troublesome construction and unsatisfactory vibration effect.

[0007] Based on this, the present invention provides an insertable vibrating rod with adjustable diameter. Compared with the prior art, by setting a separable branch rod at the lower end of the vibrating rod, the original thicker end is changed into a thinner end to adapt to different steel bar gaps and meet the vibration requirements of steel bar dense areas. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides an insertable vibrating rod with adjustable diameter and a construction method.

[0009] In view of the above technical problems, the present invention proposes an insertable vibrating rod with adjustable diameter, comprising: a vibrating rod main body, a notch is formed at the end of which to form a vibrating handle, the diameter of the vibrating handle at one end away from the vibrating rod main body is smaller than the diameter of the end of the vibrating rod main body; a limit block, convexly arranged on the outer wall of the vibrating rod main body and close to the vibrating handle; and a swing mechanism, comprising a slider, a connecting piece and a swing block; the slider is slidably penetrated through the vibrating rod main body and can abut against the limit block; one end of the connecting piece is connected to the slider, and the other end is connected to the swing block, and the swing block is arranged on the outside of the vibrating handle, and the shaft is connected to the vibrating rod main body, so that the swing block approaches or moves away from the vibrating handle as the slider slides.

[0010] Optionally, the swing mechanism further comprises an elastic member; one end of the elastic member is clamped to the vibrating rod body, and the other end is clamped to the swing block, so that the swing block is elastically reset to the outside of the vibrating handle.

[0011] Optionally, the diameter of the end of the vibrating handle away from the vibrating rod body is smaller than the diameter of the end of the vibrating handle close to the vibrating rod body.

[0012] Optionally, when the swing block is in contact with the vibrating handle, it fills the gap and is flush with the outer edge of the vibrating rod body.

[0013] Optionally, the limit block is arranged along the circumference of the vibrating rod body.

[0014] Optionally, the outer diameter of the limit block is greater than the outer diameter of the sliding block.

[0015] The present invention also provides a vibrating device, comprising the vibrating rod mentioned above.

[0016] A construction method for an insertable vibrating rod with adjustable diameter, characterized in that, if the gap between the steel bars is large and the main body of the vibrating rod can be inserted between the steel bars, there is no need to slide the slider; the slider abuts against the limit block, at which time, the vibrating handle is wrapped around the vibrating handle by the elastic force of the elastic member, so as to realize the outer layer protection of the vibrating handle, and the swing block is flush with the outer edge of the main body 1 of the vibrating rod;

[0017] If the gap between the steel bars is small and the vibrating rod body cannot be extended between the steel bars, it is necessary to slide the slider to extend the vibrating handle between the steel bars; the slider slides along the extension direction of the vibrating rod body and away from the limit block, and drives the swing block to swing through the connecting piece, so that the swing block is away from the vibrating handle, thereby exposing the vibrating handle; because the diameter of the end of the vibrating handle away from the vibrating rod body is smaller than the diameter of the end of the vibrating rod body, the vibrating handle is extended between the steel bars.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The vibrating handle is at the end of the vibrating rod body, and the vibration force can be transmitted to the vibrating handle along the vibrating rod body, and then the concrete is vibrated through the vibrating handle, wherein the diameter of the end of the vibrating handle away from the vibrating rod body is smaller than the diameter of the end of the vibrating rod body, and the vibrating handle can be extended into the smaller gap between the steel bars, thereby realizing the vibration of the concrete, and can be adapted to various gaps, thereby improving the versatility of the vibrating rod.

[0020] In addition, one end of the connecting piece is connected to the slider, and the other end is connected to the swing block, and the swing block is arranged on the outside of the vibrating handle, and the shaft is connected to the vibrating rod body, so that the swing block approaches or moves away from the vibrating handle as the slider slides, and the swing block fills the gap when it fits the vibrating handle and is flush with the outer edge of the vibrating rod body, that is, the sliding of the slider realizes the swinging of the swing block, thereby switching the vibrating rod body and the vibrating handle, and when the vibrating handle is not in use, the swing block wraps the vibrating handle to realize the outer layer protection of the vibrating handle.

[0021] Furthermore, one end of the elastic member is clamped to the vibrating rod body, and the other end is clamped to the swing block, so that the swing block is elastically reset to the outside of the vibrating handle. The swing block can rebound to the vibrating handle under the elastic force of the elastic member, thereby achieving elastic reset of the swing block. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0028] See also Figures 1 to 4The embodiment of the present invention provides an insertable vibrating rod with adjustable diameter, the vibrating rod comprises a vibrating rod body 1, a limit block 2 and a swing mechanism 3, the swing mechanism 3 comprises a slider 31, a connecting member 32 and a swing block 33. One end of the connecting member 32 is connected to the slider 31, and the other end is connected to the swing block 33, and the swing block 33 is arranged on the outside of the vibrating handle 11 of the vibrating rod body 1, and the axis is connected to the vibrating rod body 1, so that the swing block 33 moves closer to or away from the vibrating handle 11 as the slider 31 slides. A notch is provided at the end of the vibrating rod body 1 to form the vibrating handle 11, and the diameter of the end of the vibrating handle 11 away from the vibrating rod body 1 is smaller than the diameter of the end of the vibrating rod body 1. The vibration force can be transmitted along the vibrating rod body 1 to the vibrating handle 11, and then the concrete is vibrated through the vibrating handle 11, wherein the diameter of the end of the vibrating handle 11 away from the vibrating rod body 1 is smaller than the diameter of the end of the vibrating rod body 1. The vibrating handle 11 can be extended into the smaller gap between the steel bars, thereby realizing the vibration of the concrete, and can be adapted to various gaps, thereby improving the versatility of the vibrating rod.

[0029] See also Figures 1 to 4 The vibrating rod body 1 provided in the embodiment of the present invention is tubular, connected to a vibration source (not shown), and vibrates under the drive of the vibration source, and the vibration force of the vibration source is transmitted to the end of the vibrating rod body 1. A notch is provided at the end of the vibrating rod body 1 to form a vibrating handle 11, and the notch is provided along the circumference of the vibrating rod body 1, so that the caliber of the end of the vibrating handle 11 away from the vibrating rod body 1 is smaller than the caliber of the end of the vibrating rod body 1. The vibrating handle 11 is at the end of the vibrating rod body 1, and the vibration force can be transmitted to the vibrating handle 11 along the vibrating rod body 1, and then the concrete is vibrated by the vibrating handle 11, wherein the caliber of the end of the vibrating handle 11 away from the vibrating rod body 1 is smaller than the caliber of the end of the vibrating rod body 1, and the vibrating handle 11 can extend into a smaller gap between steel bars, thereby realizing the vibration of concrete, and can be adapted to various gaps, thereby improving the versatility of the vibrating rod.

[0030] See also Figure 2 and Figure 3 Specifically, the cross section of the vibrating handle 11 can be a rectangle, an isosceles trapezoid, etc. Further, in the cross section of the vibrating handle 11, the diameter of the end of the vibrating handle 11 away from the vibrating rod body 1 is smaller than the diameter of the end of the vibrating handle 11 close to the vibrating rod body 1, and the end of the vibrating handle 11 away from the vibrating rod body 1 is convenient for inserting between the steel bars, and the vibrating handle 11 has a strong hardness.

[0031] See also Figures 1 to 3 The limit block 2 provided in the embodiment of the present invention is convexly arranged on the outer wall of the vibrating rod body 1 and close to the vibrating handle 11. The limit block 2 mainly has a limiting function. Optionally, the limit block 2 is arranged along the circumference of the vibrating rod body 1.

[0032] See also Figures 1 to 4 The swing mechanism 3 provided in the embodiment of the present invention comprises a slider 31, a connecting member 32 and a swing block 33. The slider 31 is slidably arranged in the vibrating rod body 1 and can abut against the limit block 2, and the limit block 2 limits the slider 31, and the outer diameter of the limit block 2 is greater than the outer diameter of the slider 31.

[0033] The connecting member 32 may be a connecting column, a connecting rope, etc., to realize the connection between the slider 31 and the swing block 33. Specifically, the connecting member 32 is a connecting rope, one end of the connecting member 32 is connected to the slider 31, and the other end is connected to the swing block 33, thereby realizing the connection between the slider 31 and the swing block 33, so that the swing block 33 moves closer to or away from the vibrating handle 11 as the slider 31 slides.

[0034] The swing block 33 is disposed on the outer side of the vibrating handle 11 , and is axially connected to the vibrating rod body 1 , so that the swing block 33 swings around the vibrating rod body 1 to fit in with or away from the vibrating handle 11 .

[0035] Furthermore, the swing block 33 fills the gap when the vibrating handle 11 is attached, and is flush with the outer edge of the vibrating rod body 1, so that the vibrating rod 11 is guaranteed to be consistent with the vibrating rod body 1 when not in use, maintaining the size of the vibrating rod body 1, and vibrating the concrete with the size of the vibrating rod body 1. At the same time, the sliding of the slider 31 realizes the swing of the swing block 33, thereby switching the vibrating rod body 1 and the vibrating handle 11, and when the vibrating handle 11 is not in use, the swing block 33 wraps the vibrating handle 11 to realize the outer layer protection of the vibrating handle.

[0036] See also Figures 1 to 4 In addition, the swing mechanism 3 further includes an elastic member 34. The elastic member 34 may be a torsion spring, one end of the elastic member 34 is clamped to the vibrating rod body 1, and the other end is clamped to the swing block 33, so that the swing block 33 is elastically reset to the outside of the vibrating handle 11, and the swing block 33 can rebound to the vibrating handle 11 under the elastic force of the elastic member 34, thereby realizing the elastic reset of the swing block 33.

[0037] The process of using the vibrator is as follows:

[0038] 1. If the gap between the steel bars is large and the vibrating rod body 1 can be inserted between the steel bars, there is no need to slide the slider 31. The slider 31 abuts against the limit block 2. At this time, the vibrating handle 11 is wrapped by the elastic force of the elastic member 34 to achieve outer protection of the vibrating handle 11, and the swing block 33 is flush with the outer edge of the vibrating rod body 1.

[0039] 2. If the gap between the steel bars is small and the vibrating rod body 1 cannot be inserted between the steel bars, it is necessary to slide the slider 31 so that the vibrating handle 11 can be inserted between the steel bars. The slider 31 slides along the extension direction of the vibrating rod body 1 and moves away from the limit block 2, and drives the swing block 33 to swing through the connecting piece 32, so that the swing block 33 moves away from the vibrating handle 11, thereby revealing the vibrating handle 11. Since the diameter of the end of the vibrating handle 11 away from the vibrating rod body 1 is smaller than the diameter of the end of the vibrating rod body 1, the vibrating handle 11 can be inserted between the steel bars.

[0040] The vibrating device of the present invention comprises the above-mentioned vibrating rod.
