Concrete vibrator

Abstract

The invention discloses a concrete vibrator. A middle cover, a cover plate, a rear end cover, a tail cover and a case form a casing part of the concrete vibrator; a reduction gearbox is located at oneend of the case; an armature assembly, a primary driven gear, a spindle and a stator assembly are arranged in the casing part; one end of a cable assembly extends out of the case; an arc-shaped support frame assembly is fixedly mounted outside the casing part; the support frame assembly is connected with the upper end of the reduction gearbox through bolts, square nuts and supporting sleeves; thereduction gearbox is connected and fixed with the middle cover through screws A, and the contact surface of the reduction gear box and the middle cover is sealed by a seal ring. As for the product, motor fixation adopts suspended support by a steel tube framework, and the problems that a chassis type support motor possibly rolls during use on a construction site, the motor is stained due to the fact that the motor easily makes contact with concrete and ventilation and heat dissipation of the motor are affected are well solved. Besides, general parts are adopted in the design, so that the product making cost is reduced, and the time for recouping the capital outlay is shortened.

Description

technical field [0001] The invention relates to a concrete vibration device, in particular to a single-phase concrete vibrator. Background technique [0002] According to the statistics of "China's Power Tool Industry Production and Sales Demand Forecast and Transformation and Upgrading Analysis Report", power tools are mainly divided into metal cutting power tools, grinding power tools, assembly power tools and railway power tools. [0003] Common electric tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers. However, a concrete vibrator is an electric tool that compacts poured concrete by vibrating. [0004] With the recovery and prosperity of the real estate industry and the construction industry, the market demand for concrete vibrators is increasing day by day. So far, there are many companies in the industry with an annual output of about 200,000 unit...

AI Technical Summary

Problems solved by technology

[0010] One: The existing concrete vibrator uses a chassis-type supporting motor. During use, the motor is easily in contact with the concrete and contaminates the motor, which will inevitably affect the ventilation and heat dissipation of the motor.

[0011] Second: The connection and sealing of the corresponding casing of the existing concrete vibrator is not firm, and the overall performance is poor. Its center of gravity is unstable and may roll over during use on the construction site, which seriously affects the vibration quality and effect.

[0012] Third; for the existing concrete vibrator, along with the vibration, the auxiliary units such as cable assemblies and switch assemblies are easily damaged or malfunction due to vibration

[0013] Fourth: According to market research, it is found that the concrete vibrator used in the market has a complex structure, is expensive, and has high production costs, which will directly affect the economic benefits of use.
