Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, and specifically relates to a hexagonal vibrating rod. Background Art

[0002] Concrete is a building material widely used in the construction industry. Since concrete contains a large amount of gas and moisture after mixing, in order for the concrete to reach its designed strength, the bubbles must be removed, its density must be ensured, and tamping must be carried out to make the concrete densely combined and eliminate the honeycombed surface of the concrete, so as to improve its strength and ensure the quality of concrete components.

[0003] During the pouring of concrete, a vibrator is usually used to vibrate and expel gas. The vibrator, also known as a high-frequency vibrator, consists of a driver, a hose, a vibrator and other components. It generates high-frequency vibrations to quickly expel bubbles from the components, making cement, sand and gravel and the steel frame tightly connected together to improve the compactness of the concrete.

[0004] At present, the vibrating rods on the market are all cylindrical, and the effective vibrating surface during vibration is also circular. In the process of vibration, multiple vibrating rods are generally inserted into the concrete for vibration at the same time, or one vibrating rod is inserted into the concrete for vibration multiple times. Since the effective vibrating surface is circular, in order to avoid dead corners of vibration during concrete pouring, the insertion points of two adjacent vibrating rods are set closer during the actual vibration process, resulting in a large area of ​​repeated vibration, wasting manpower and material resources.

[0005] Another problem is how to increase the vibrating force when the volume of the vibrating rod is constant, which is also a major technical problem in the current vibrating rod field. Utility Model Content

[0006] The utility model provides a hexagonal vibrating rod, which solves at least one of the above technical problems. The specific technical solution is as follows:

[0007] A hexagonal vibrating rod comprises a shell and a vibrating shaft, wherein the shell is rotatably connected to the vibrating shaft, the shell comprises a vibrating part and a connecting part, and the cross section of the vibrating part is a regular hexagon.

[0008] Through the above technical solution, the cross section of the vibrating part is a regular polygon, so that the effective vibrating surface of the vibrating rod is a regular hexagon, which is more convenient for the layout of the insertion point of the vibrating rod, so as to reduce the repeated vibration area, reduce the waste of manpower and material resources, and improve work efficiency. Compared with the vibrating rod with a regular quadrilateral or regular pentagonal cross section of the vibrating part, the vibrating part of the vibrating rod is less likely to get stuck in the gap between the steel bars in the concrete.

[0009] Preferably, the end surface of the connecting end between the vibrating portion and the connecting portion is arc-shaped.

[0010] The technical solution facilitates the pulling out of the vibrating rod after the vibration is completed, and the vibrating portion of the vibrating rod is not easily stuck in the gap between the steel bars in the concrete.

[0011] Preferably, the vibrating part and the connecting part are connected by threads.

[0012] Through the above technical solution, the vibrating part can be disassembled separately, which is convenient for maintenance and installation.

[0013] Preferably, the vibrating part and the connecting part are integrally formed.

[0014] Through the above technical solution, the structural strength of the connection between the vibrating part and the connecting part is increased.

[0015] Preferably, the vibration shaft is connected to the housing via a bearing.

[0016] Through the above technical solution, the structure of the vibrating rod is made simpler, and it is convenient for loading, unloading and maintenance.

[0017] Preferably, the connecting portion is connected to a hose, and the vibration shaft is connected to a flexible transmission shaft.

[0018] Through the above technical solution, the movement of the vibrator can be more free.

[0019] Preferably, the vibration shaft includes a first connecting part, an eccentric shaft and a second connecting part, and the two ends of the eccentric shaft are respectively connected to the first connecting part and the second connecting part; the first connecting part and the second connecting part are coaxially arranged, and are respectively used to be rotatably connected to the outer shell; the second connecting part is connected to the transmission shaft, and is used to drive the vibration shaft to rotate; the cross-section of the eccentric shaft is in the shape of a superior arc, and the outer surface of the eccentric shaft along the axial direction is surrounded by a plane and a circular arc surface, and a first reinforcement part is arranged on the plane, and the first reinforcement part is located on any side of the plane close to both sides of the arc surface, and the surface of the first reinforcement part close to the arc surface is arc-shaped, and the arc surface of the reinforcement part is concentrically arranged with the arc surface of the eccentric shaft.

[0020] By adopting the above technical solution, reinforcing ribs are arranged on the eccentric shaft, which can improve the structural strength of the eccentric shaft and prevent the eccentric shaft from bending under the action of centrifugal force when rotating at high speed. By arranging the reinforcing ribs on one side of the eccentric shaft, the distance between the center of mass and the center of rotation can be increased while the total mass and the space occupied by the eccentric shaft remain unchanged, so as to increase the vibration force.

[0021] Preferably, the outer side surface of the reinforcing rib is arc-shaped, and the radius of the arc is the same as the radius of the eccentric shaft.

[0022] Through the above technical solution, when the total mass and radius of the eccentric shaft remain unchanged, the distance between the center of mass of the eccentric shaft and the center of rotation axis is larger.

[0023] Preferably, a second reinforcement portion is provided at a connection between the eccentric shaft and the first connection portion, and a third reinforcement portion is provided at a connection between the eccentric shaft and the second connection portion.

[0024] Through the above technical solution, the connection strength between the eccentric shaft and the first connection part and the connection strength between the eccentric shaft and the second connection part are increased.

[0025] Preferably, the second connecting portion is provided with threads, and the threads are used to connect with the transmission shaft.

[0026] Through the above technical solution, the connection between the second connecting part and the transmission shaft is made simpler and convenient for assembly and disassembly.

[0030] 3. The reinforcing ribs are arranged on one side of the eccentric shaft, which can increase the distance between the center of mass and the center of rotation while keeping the total mass and the space occupied by the eccentric shaft unchanged, so as to increase the vibration force.

[0038] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the drawings of the specification. In the following description, many specific details are set forth to facilitate a full understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1

[0041] like Figure 1-3 As shown, a hexagonal vibrating rod comprises a housing 1 and a vibrating shaft 2, wherein the housing 1 and the vibrating shaft 2 are connected via a bearing 3, and the housing 1 comprises a vibrating portion 11 and a connecting portion 12, wherein the vibrating portion 11 and the connecting portion 12 are connected via a thread. The cross section of the vibrating portion 11 is a regular hexagon. The effective vibrating surface of the vibrating rod is hexagonal, which makes it easier to arrange the insertion point of the vibrating rod, thereby reducing the repeated vibrating area, reducing the waste of manpower and material resources, and improving work efficiency.

[0042] The vibration effect of this embodiment is compared with that of a vibrating rod with a circular vibrating section. Figure 5 As shown, 51 is the insertion point of the vibrating rod of the circular cross section of the vibrating portion 11, 52 is the effective vibrating surface, 53 is the insertion point of the vibrating rod of the present application, and 54 is the effective vibrating surface. Obviously, the vibrating rod of the scheme described in this embodiment is more convenient to layout, and at the same number of insertion points, the vibrating rod of this embodiment can effectively vibrate a larger area.

[0043] The end surface 111 of the connecting end of the vibrating part 11 and the connecting part 12 is arc-shaped. The arc-shaped surface is more conducive to the vibrating part being pulled out from the gap of the steel bars after the vibration is completed.

[0044] like Figure 4As shown, the vibration shaft 2 includes a first connection part 21, an eccentric shaft 22 and a second connection part 23, the first connection part 21, the eccentric shaft 22 and the second connection part 23 are integrally formed, the outer surface of the eccentric shaft 22 along the axial direction is surrounded by a plane and an arc surface, a first reinforcement part 221 is provided on the plane, the first reinforcement part 221 is located on any side of the plane close to the two sides of the arc surface, the eccentric shaft 22 and the first reinforcement part 221 are integrally formed, the surface of the first reinforcement part 221 close to the arc surface is arc-shaped, and the arc surface of the reinforcement part is concentrically arranged with the arc surface of the eccentric shaft 22. The reinforcement part can strengthen the structural strength of the eccentric shaft 22, and at the same time, its position on the eccentric shaft 22 is designed so that the distance between the center of mass and the rotation axis after the reinforcement part and the eccentric shaft 22 are combined is farther.

[0045] The first connection part 21 and the second connection part 23 are respectively located at both ends of the eccentric shaft 22, and a second reinforcement part 222 is provided at the connection between the eccentric shaft 22 and the first connection part 21, and a third reinforcement part 223 is provided at the connection between the eccentric shaft 22 and the second connection part 23. The connection strength between the eccentric shaft and the first connection part and the connection strength between the eccentric shaft and the second connection part are strengthened.

[0046] The first connection part 21 and the second connection part 23 are coaxially arranged and are respectively used for rotational connection with the outer shell. Specifically, the first connection part 21 is rotationally connected to the outer shell at the end of the vibrating rod through a bearing. The second connection part 23 is rotationally connected to the outer shell at one end of the vibrating rod close to the driving mechanism through a rotating shaft. The second connection part 23 is provided with a thread 231, and the thread 231 is used to connect with the transmission shaft. The vibration shaft can rotate in the vibrating rod under the drive of the driving mechanism.

[0047] The cross section of the eccentric shaft 22 is in an arc shape, so that the center of mass of the eccentric shaft 22 and the center of rotation are not in the same straight line. When the eccentric shaft 22 rotates under the drive of the driving mechanism, the vibrating rod generates high-frequency vibration under the action of centrifugal force.

[0048] The outer surface of the eccentric shaft 22 along the axial direction is formed by a plane and an arc surface, and a first reinforcement part 221 is provided on the plane. The first reinforcement part 221 is located on either side of the plane close to the arc surface. The eccentric shaft 22 and the first reinforcement part 221 are integrally formed, and the surface of the first reinforcement part 221 close to the arc surface is arc-shaped, and the arc surface of the reinforcement part is concentrically arranged with the arc surface of the eccentric shaft 22. The reinforcement part can enhance the structural strength of the eccentric shaft 22, and at the same time, its position on the eccentric shaft 22 is designed so that the distance between the center of mass and the rotation axis after the reinforcement part and the eccentric shaft 22 are combined is farther.

[0050] The vibrating part 11 and the connecting part 12 are integrally formed, and the rest is the same as the first embodiment.

[0051] Example 3

[0052] The connecting portion 12 is connected to the hose, the vibration shaft 2 is connected to the flexible transmission shaft, and the rest is the same as in the first embodiment.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
