Abstract
Description
Technical Field

Its main purpose is to expel bubbles in the surface of the concrete to eliminate phenomena such as honeycombed surface of the concrete, to improve its strength and to ensure the quality of the concrete components. This is because there are some bubbles in the surface of the concrete components after pouring, which are formed by the air brought in by mixing the concrete. If they are not removed, the surface of the concrete components will contain a large number of holes after hardening, and the density will be low, which will affect the compressive performance of the components.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0028] In order to solve the technical problem that the number and size of vibrating rods in the prior art are fixed, which is not convenient to meet the vibration needs of special parts of cast structures and the practicality needs to be improved, the utility model provides a concrete vibrator, which can select and apply vibrating long rods of corresponding sizes according to actual needs; and can simultaneously place multiple vibrating long rods at different parts of concrete for vibrating according to the sizes of the vibrating long rods, while ensuring the vibration effect and improving the vibration efficiency; at the same time, multiple second vibrating short rods can better adapt to the special parts of the component to ensure the vibration effect of the concrete in the special parts, and the practicality is good.
[0029] See also Figure 1 , Figure 1 Schematic diagram of the structure of a concrete vibrator in an embodiment of the utility model, the concrete vibrator includes a power body 1, a first vibrating assembly 2 and a second vibrating assembly 3; the first vibrating assembly 2 includes a plurality of first flexible shafts 21 and a plurality of vibrating long rods 22, one ends of the plurality of first flexible shafts 21 are respectively connected to the power body 1 in a transmission manner, and the plurality of vibrating long rods 22 are respectively arranged on the plurality of first flexible shafts 21, and at least some of the vibrating long rods 22 have different sizes; the second vibrating assembly 3 includes a second flexible shaft 31 and a plurality of vibrating short rods 32, the second flexible shaft 31 is connected to the power body 1 in a transmission manner, and the plurality of vibrating short rods 32 are arranged on the second flexible shaft 31 and are arranged at intervals along the extension direction of the second flexible shaft 31.
[0030] In the concrete vibrator provided by the utility model, the power body 1 transmits power to the vibrating long rod 22 and the vibrating short rod 32 via the first flexible shaft 21 and the second flexible shaft 31, so as to realize the vibration of the concrete by the vibrating long rod 22 and the vibrating short rod 32. And because a plurality of vibrating long rods 22 are provided, and the sizes of the plurality of vibrating long rods 22 are set to be different, the vibrating long rods 22 of corresponding size specifications can be selected and applied according to actual needs; and the plurality of vibrating long rods 22 can be placed at different positions in the concrete for vibration according to the sizes of the vibrating long rods 22, thereby improving the vibration efficiency while ensuring the vibration effect. In addition, a plurality of second vibrating short rods 32 are arranged at intervals along the length direction of the second flexible shaft 31. In this way, the vibrating long rod 22 and the plurality of second vibrating short rods 32 can be pre-buried in the corners of the structure, the steel bar protective layer and the bends of the prestressed pipe before pouring the concrete. The vibrating long rod 22 and the plurality of second vibrating short rods 32 can better adapt to the special parts of the component to ensure the vibration effect of the concrete in the special parts, and have good practicality.
[0031] It should be noted that in this solution, the power assembly adopts a rotary power drive, and uses multiple output ends to independently drive each first flexible shaft 21 and the second flexible shaft 31 to transmit power to the corresponding vibrating long rod 22 and vibrating short rod 32, so that the vibration intensity of each vibrating rod can be flexibly adjusted. It should be understood that the driving structure and principle of the power assembly, and the structure and transmission principle of the flexible shaft are prior art and are not described in detail here. In addition, the length of the vibrating long rod 22 is greater than the length of the vibrating short rod 32. The length of the vibrating short rod 32 enables the second vibrating assembly 3 to be better applicable to the special parts of the cast component, and has better flexibility.
[0032] In addition, in this solution, the vibrator is pre-buried, and the long vibrator rod 22 and the short vibrator rod 32 are installed in the pouring structure before concrete pouring, especially in the area with dense steel bars and key parts of the structure, and in the places where the vibrator rod is difficult to insert after pouring concrete. In this way, there are better visual conditions, and the vibrator rod can be accurately installed, which prevents the phenomenon that the vibrator is difficult to insert in some parts after the concrete pouring in the later stage, and the workers miss the vibration.
[0033] In one embodiment, a temperature sensor is disposed on the first flexible shaft 21 and the second flexible shaft 31. In addition, a temperature regulator is disposed on the first flexible shaft 21 and the second flexible shaft 31.
[0034] In this way, the temperature of concrete can be monitored in real time during the concrete pouring process, and the temperature of concrete can be adjusted according to the characteristics of concrete. After the vibration is completed, the vibrating rod is pulled out and reused. It should be noted that the specific structure and principle of the temperature sensor and the temperature regulator are prior art and will not be described in detail here.
[0035] In one embodiment, see Figure 2 The lengths and / or diameters of the plurality of vibrating rods 22 are different.
[0036] In this embodiment, vibrating rods 22 of various lengths and diameters are arranged at the end of the first vibrating assembly 2, and the size of each vibrating rod 22 is set to be different, so that the vibrating rods 22 of multiple lengths and diameters can vibrate simultaneously, thereby improving the vibration efficiency, and the vibrating rods 22 of corresponding sizes can be selected as needed, which has better practicality.
[0037] In one embodiment, the first vibrating assembly 2 is provided with multiple groups, and the diameters of the multiple vibrating rods 22 in the same group are different, but the lengths are the same, and the lengths of the vibrating rods 22 in the multiple groups are different; or, the first vibrating assembly 2 is provided with multiple groups, and the lengths of the multiple vibrating rods 22 in the same group are different, but the diameters are the same, and the diameters of the vibrating rods 22 in the multiple groups are different.
[0038] In this embodiment, one of the two parameters of the diameter and length of the vibrating rods 22 in the same group is set to be different, while the other parameter of the vibrating rods 22 in multiple groups is set to be different, so as to facilitate user classification and select corresponding vibrating rods 22 by group, thereby improving practicality.
[0039] In one embodiment, see Figure 3 , at least some of the vibrating short rods 32 have different lengths and / or diameters.
[0040] In this embodiment, the lengths and diameters of the plurality of vibrating short rods 32 are also set to be different, thereby further improving the vibration efficiency and the vibration flexibility.
[0041] In one embodiment, the lengths of the plurality of vibrating short rods 32 gradually increase in a direction away from the power body 1 .
[0042] In this solution, the lengths of the multiple vibrating rods 32 are gradually increased in the direction away from the power body 1. In this way, the vibrating rods 32 buried deeper are longer, thereby increasing the area covered by the vibrating rods 32 at depth, thereby improving its vibration capacity and enhancing the air bubble discharge effect deep in the concrete.
[0043] In one embodiment, the second vibrating assembly 3 is provided with a plurality of groups, and at least some of the groups have different numbers of vibrating short rods 32 .
[0044] In this embodiment, multiple groups of second vibrating assemblies 3 are provided, and the numbers of vibrating rods 32 of the multiple groups of second vibrating assemblies 3 are set to be different, so that the second vibrating assemblies 3 with corresponding numbers of vibrating rods 32 can be selected according to actual needs, thereby improving flexibility.
[0045] In one embodiment, the second vibrating assembly 3 is provided with a plurality of groups, the vibrating short rods 32 in the same group have the same size, and the vibrating short rods 32 in the plurality of groups have different lengths and / or diameters.
[0046] Similarly, in this embodiment, the sizes of the vibrating rods 32 in the same group are set to be the same, and the sizes of the vibrating rods 32 in multiple groups are set to be different, so that they can be classified into groups and the second vibrating components 3 of corresponding sizes can be selected, which is more practical.
[0047] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:
[0048] In this scheme, firstly, the vibrating rod is embedded before the concrete is poured, which has good visual conditions and can accurately install the vibrating rod (long vibrating rod 22 and short vibrating rod 32), so as to prevent the phenomenon that the vibrating rod is difficult to insert in some parts and the workers miss the vibration after the concrete is poured in the later stage; secondly, the vibrating rods of various specifications are used at the end of the vibrator, which can meet the concrete vibration of various special parts, such as the corners of the structure, the protective layer of the steel bars, and the bends of the prestressed pipes, so as to ensure the vibration effect of the concrete; thirdly, the temperature of the concrete can be monitored in real time during the concrete pouring process, and the concrete temperature can be adjusted according to the concrete characteristics. After the vibration is completed, the vibrating rod at the end of the vibrator can be pulled out and reused.
[0049] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
