Description

A concrete vibrating table for sleeper production

technical field

The utility model relates to a railway sleeper production equipment, in particular to a concrete vibrating table used for the production of the sleeper.

Background technique

At present, in the production of railway ballastless track concrete sleepers, various processes such as long-line pedestal method and immediate demoulding method are used. With the rapid development of my country's railway industry, the construction of quasi-high-speed and high-speed railways is being accelerated. High-speed railways have a large demand for new sleepers, and their quality requirements are also stricter. Existing concrete sleeper production equipment, especially concrete vibration No matter whether it is production efficiency or product quality assurance, it can no longer meet the new requirements. There is an urgent need for a concrete vibrating device that can ensure product quality and higher production efficiency to be put into production.

Utility model content

The purpose of this utility model is to provide a concrete vibrating table for sleeper production with reasonable structural design, high production efficiency and guaranteed product quality, aiming at the deficiencies of the above-mentioned prior art.

In order to achieve the above object, the technical solution adopted by the utility model is: a concrete vibrating table for sleeper production, characterized in that it includes two vibrating platforms 2 arranged in parallel, and the vibrating platform 2 is provided with frequency, amplitude With the vibration motor 3 with adjustable steering, the vibration platform 2 is connected to the vibration platform support 5 through the shock absorber 4, and the vibration platform support 5 is arranged on both sides of the vibration platform 2; a lifting device is arranged between the two vibration platforms 2 to fix Table 1, the lifting device fixed table 1 is provided with a conveying roller table 6 composed of rotating rollers 9; a conveying roller table lifting device 8 is arranged between the lifting device fixed table 1 and the conveying roller table 6.

Compared with the prior art, the utility model has the following advantages: the utility model has reasonable structural design, advanced technology, high degree of automation, good compactness of concrete after vibration, vertical vibration and horizontal vibration can be realized through the control system, and the vibration frequency band is rich. The vibration frequency, amplitude and working time can be adjusted according to the technical parameters of the sleeper production. The utility model can be widely used in the vibration of various sleepers during pouring, especially for the production of new sleepers for high-speed railways.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Fig. 1 and Fig. 2, the utility model comprises two vibrating platforms 2 arranged in parallel, the two ends of the vibrating platform 2 are provided with a vibrating motor 3 with adjustable frequency, amplitude and steering, and the vibrating motor 3 is fixedly installed on the vibrating At both ends of the platform 2, the vibration platform 2 is connected to the vibration platform support 5 through the shock absorber 4, and the vibration platform support 5 is arranged on both sides of the vibration platform 2; between the two vibration platforms 2, a lifting device fixing table 1 is arranged , above the lifting device fixed table 1 is provided with a conveying roller table 6 composed of rotating rollers 9; between the lifting device fixed table 1 and the conveying roller table 6 is provided with a conveying roller table lifting device 8.

In order to ensure that the vibrating platform 2 has sufficient strength, the vibrating platform 2 is a box-shaped structure.

In order to place the mold on the vibrating platform 2 stably, an elastic backing plate 12 is arranged on the vibrating platform 2 .

As shown in FIG. 3 , the conveying roller table lifting device 8 is a pneumatic mechanism composed of an inflatable air bag 10 and an air valve 11 .

When the utility model is working, the empty model that has been cleaned and installed with accessories such as steel bar trusses is placed on the vibrating platform 2 and fixed through the conveying roller table 6, and the concrete distribution vehicle automatically measures and pours concrete into the model. Under the control of the control system, Driven by the vibration motor 3, the vibration platform 2 can realize various working conditions such as low-frequency vertical vibration, high-frequency vertical vibration, and low-frequency horizontal vibration for a specific period of time according to the technical parameters of the concrete vibration of the sleeper. The road lifting device 8 raises the conveying roller table 6, so that the solid model that has been shaken is separated from the vibrating platform 2, and enters the next process.
