Description

Technical Field

[0001] The invention relates to building construction equipment technology, in particular to a concrete plate vibrator for building ground construction. Background Art

[0002] In the process of building ground construction, the concrete plate vibrator is a key equipment. Most existing vibrators use the centrifugal force generated by the rotation of the eccentric block to induce vibration, thereby achieving the vibration of the concrete. However, most existing concrete plate vibrators can only achieve a single vibration method, which brings many limitations in actual construction. Different construction scenarios have different requirements for vibration methods, such as:

[0003] High-rise building floor pouring: It is necessary to reduce the impact of lateral vibration on the formwork to prevent the formwork from displacement;

[0004] Embedded parts in concrete: lateral vibration needs to be reduced to prevent the embedded parts from moving;

[0005] Construction in narrow spaces or close to existing structures: vibrators that can reduce vibration interference with surrounding structures are required;

[0006] Subfloor or concrete without embedded parts: Horizontal vibration can be used to help paving while vibrating;

[0007] High-strength concrete: More intensive vibration may be required.

[0008] Despite these different needs, most existing vibrators are of a single design and cannot adjust the vibration mode according to specific construction scenarios. Therefore, their applicability is not high. In order to meet the needs of different construction scenarios, there is an urgent need for a concrete plate vibrator that can flexibly adjust the vibration mode. Summary of the invention

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See also Figures 1 to 3 , a concrete plate vibrator for floor construction of building, comprising a vibrating plate 1, a fixing frame 2, a vibrating component 4, a driving component 5 and a connecting component 6;

[0038] The vibration component 4 is mounted on the vibration plate 1. The vibration component 4 includes an A drive shaft 41 and a B drive shaft 42. The A drive shaft 41 and the B drive shaft 42 are both rotatably mounted on the vibration plate 1. Two eccentric blocks 43 are fixedly sleeved on the outside of the A drive shaft 41 and the B drive shaft 42.

[0039] One side of the driving component 5 is connected to the vibrating component 4. The driving component 5 is used to drive the A driving shaft 41 and the B driving shaft 42 to rotate synchronously around their respective axes, and the driving component 5 can be switched between a first state and a second state. When the driving component 5 is in the first state, the rotation directions of the A driving shaft 41 and the B driving shaft 42 are opposite; when the driving component 5 is in the second state, the rotation directions of the A driving shaft 41 and the B driving shaft 42 are the same;

[0040] The fixing frame 2 is installed on the top of the vibration plate 1 , and the connecting component 6 is used to connect the vibration plate 1 and the fixing frame 2 .

[0041] Most existing vibrators use the vibration generated by the centrifugal force when the eccentric block 43 rotates to achieve the vibration of concrete. In the actual construction process, different construction scenes require different vibration methods. For example, for the pouring of floor slabs of some high-rise buildings, it is necessary to reduce the impact of lateral vibration on the formwork to prevent displacement. For example, when embedded parts are embedded in the concrete, it is also necessary to reduce lateral vibration to prevent the embedded parts from moving. For example, when constructing in a narrow space or near an existing structure, an offset vibrator can reduce the vibration interference to the surrounding structure. For the bottom floor or concrete without embedded parts, horizontal vibration can be used to help spread while vibrating. For high-strength concrete, more intensive vibration may be required. However, most existing vibrators can only achieve one vibration method at the same time, and their applicability is not high.

[0042] To this end, the present application drives the rotation of the A drive shaft 41 and the B drive shaft 42 through the driving component 5, and can control the rotation direction of the A drive shaft 41 and the B drive shaft 42 to adapt to different working scenarios. When the driving component 5 is in the first state, the rotation directions of the A drive shaft 41 and the B drive shaft 42 are opposite, and the horizontal vibrations generated by the eccentric blocks 43 on the A drive shaft 41 and the B drive shaft 42 offset each other; when the driving component 5 is in the second state, the rotation directions of the A drive shaft 41 and the B drive shaft 42 are the same, and horizontal and vertical vibrations will be generated at the same time, thereby adapting to different construction scenarios.

When the driving component 5 is in the second state, the B driving shaft 42 is connected to the A bevel gear 54 through the transmission assembly 53, and the A bevel gear 54 drives the A driving shaft 41 to rotate. The A driving shaft 41 and the B driving shaft 42 have the same rotation direction. At this time, the vibrator generates horizontal and vertical vibrations;

[0045] When the driving component 5 is in the first state, the B driving shaft 42 is connected to the B bevel gear 55 through the transmission assembly 53, and the B bevel gear 55 drives the B driving shaft 42 to rotate.
