Pneumatic concrete vibrator

Abstract

The invention relates to a pneumatic concrete vibrator, and belongs to the technical field of concrete vibrators. The pneumatic concrete vibrator comprises a pneumatic motor and a vibrating rod. The air inlet of the pneumatic motor is connected with a switch block, and the air outlet of the pneumatic motor is provided with a silencer. A guide sleeve assembly is installed on the side wall of a motor shell and corresponds to a transmission shaft of the pneumatic motor. A chuck component is arranged in the guide sleeve assembly, one end of the chuck component is fixed to the transmission shaft, and the other end of the chuck component is connected with the vibrating outer ring of the connecting end of the vibrating rod. The pneumatic concrete vibrator is developed according the specific work environment of an underground coal mine containing gas and coal mine dust and the demands of the majority of users, and is an essential tool for pouring concrete members of the underground coal mine and other mines. With compressed air serving as a power source and the blade type pneumatic motor providing power, the pneumatic concrete vibrator has the advantages of being large in vibrating amplitude, high in frequency, small in size, light in weight, reasonable in structure, convenient to install, operate, maintain and use and the like, and is safe and reliable to use in the underground coal mine.

Description

technical field [0001] The invention relates to a pneumatic concrete vibrator, belonging to the technical field of concrete vibrators. Background technique [0002] Concrete vibrator is an important machine in modern concrete engineering construction. A vibrator is required for pouring concrete components. But most of the supplies on the market are electric vibrators, which are very unsafe to use in coal mines. Because it is an electric vibrator, coupled with the influence of the underground environment of the coal mine, the cable wears a lot when used in the coal mine, and the amount of replacement and maintenance is large. If the damaged cable is not disposed of in time, it is easy to generate sparks. Coal mines cannot work safely underground. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is: provide a kind of pneumatic concrete vibrator, which is safe and reliable w...
