Electric pipe hole chamfering trolley

Abstract

The invention relates to an electric pipe hole chamfering trolley, which comprises a trolley body platform. Wheels are arranged at the bottom of the trolley body platform, two armrests are arranged in the rear of the trolley body platform, a counterweight block is arranged in the front of a wheel rotating shaft on the trolley body platform, a motor is arranged at the back of the wheel rotating shaft on the trolley body platform, a drill bit perpendicular to the trolley body platform is downwardly arranged on a rotary shaft of the motor, and bent handles are arranged at ends of the two armrests respectively. An operator can hold the bent handles with hands to control the drill bit to rapidly chamfer pipe holes on a pipe sheet and a baffle with large diameters, and the electric pipe hole chamfering trolley is convenient and flexible in application. Holding time of large equipment can be shortened, so that profitability in unit time is improved for enterprises. The counterweight block and the motor are arranged in the front and at the back of the wheel rotating shaft respectively, the labor intensity of operators is reduced, operation is facilitated, production cost can be reduced, and the production cycle of products is greatly shortened.

Description

technical field [0001] The invention relates to a tube hole chamfering device, in particular to an electric tube hole chamfering trolley suitable for chamfering the tube holes of a heat exchanger tube plate and a baffle, and belongs to the field of mechanical technology. Background technique [0002] At present, when the tube holes of the tube sheet and baffle of the traditional heat exchanger are chamfered, the radial drill is usually used for positioning chamfering. Because the radial drill has the defect of inflexibility in operation, the tube sheet and baffle When the diameter is relatively large, only a large radial drilling machine can be used for chamfering, which is inconvenient to operate; when the output of the heat exchanger is relatively high, it will bring about a large workload and low work efficiency, resulting in high production costs. Contents of the invention [0003] The problem to be solved by the present invention is to provide an electric tube hole ch...
