Example Embodiment

[0042] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0043] like figure 1 , figure 2As shown in the figure, a concrete vibrating rod includes a shell 1, an eccentric shaft 5, a bearing seat 4, an AC motor 3, a frequency conversion controller 2, a muffler sleeve 6, a rod head 11, a sound sensor 10, a connecting part, a heating phase Change sleeve 14, temperature sensor. The interior of the housing 1 is divided into upper and lower chambers, and the upper and lower chambers are separated by a bearing seat 4 . A frequency conversion controller 2 and an AC motor 3 are arranged in the upper chamber. The frequency conversion controller 2 is connected to an external AC power supply 9 , and the frequency conversion controller 2 is connected to the AC motor 3 for controlling the rotational speed of the AC motor 3 . The upper end of the eccentric shaft 5 is connected with the output shaft of the AC motor 3, and t...

Abstract

The invention relates to a concrete vibrating rod. The concrete vibrating rod comprises a shell (1), the interior of the shell is divided into an upper chamber and a lower chamber through a bearing pedestal (4), the upper chamber is provided with a variable frequency controller (2) and an alternating current motor (3), an eccentric shaft (5) is connected with an output shaft of the alternating current motor, the lower chamber is sequentially provided with a silencing cover (6) and a bushing (8), and a sound sensor (10) connected with the variable frequency controller is arranged outside the shell. A connection portion arranged on the outer surface of the shell fixes a heating phase-change cover (14) to the outer surface of the shell. The heating phase-change cover is a sealed cavity filled with phase-change materials (19), an electric heating device (20) is arranged on the inner side of the outer wall (15) of the heating phase-change cover, a reflecting film (21) and a heat insulation layer (22) are sequentially arranged on the inner side of the inner wall (16) of the heating phase-change cover, and the outer surface of the outer wall of the heating phase-change cover is provided with a temperature sensor connected with a temperature control device of the electric heating device. The concrete vibrating rod is used for concrete pouring, can achieve vibration and heating of concrete, effectively saves energy, and reduces noise.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a vibrating rod for pouring concrete. Background technique [0002] In the field of building construction, the vibrating rod is one of the commonly used vibrating devices in concrete pouring. During the concrete pouring process, since the stirred concrete contains a large amount of gas and water, the vibrating rod generates high-frequency vibration inside the concrete, which makes the concrete compact and thus ensures the pouring quality. However, during construction in winter or in alpine regions, during the vibration process of the vibrator, on the one hand, it is easy to cause the heat loss of the poured concrete, resulting in the pouring temperature on the concrete pouring surface being lower than the relevant requirements; on the other hand, the vibration is , The temperature difference between the upper and lower layers of the intermittent surface is large, which makes...
