Embodiment 1

[0029] Such as figure 1 The shown one is installed at the end of the motor of the industrial door machine, and can realize the transmission device of electric and manual automatic switching. It includes a bidirectional drive axial device, a hand chain wheel 2, a support seat 3, a clutch device of the motor and a power switch 5. The two-way driving axial device is installed on the support base 3, which includes: a two-way guide cam 11, a mandrel 12, and a critical fixing device.

[0030] The bidirectional pilot cam 11 is fixed on the support seat 3, and can be rotated without displacement. The bidirectional pilot cam 11 is divided into two equal parts in the axial direction, and each part is provided with a helical surface 111 or a helical groove in the same direction. 111;

[0031] One end of the mandrel 12 is connected to the hand sprocket 2, and rotates synchronously with the hand sprocket 2, and the other end is inserted into the bidirectional lead cam 11, and part A is pr...

Abstract

The invention provides a transmission device of an industrial door opener capable of automatic switching. The invention mainly aims to provide a two-way lead cam and a critical fixing device, wherein the two-way lead cam is fixed in axial direction and does not rotate in an initial state under the action of the critical fixing device; when a hand-pulled chain wheel fixed on the same mandrel along with the two-way lead cam is pulled in random directions, a part A can slide from a low point to the highest point of a spiral surface or a thread groove; thus, the mandrel moves in axial direction towards the same direction and cooperates with a bevel gear pair and a power supply switch to switch motor drive to manual drive flexibly; and when a hand-pulled chain is loosened, motor drive is switched back under the action of a mandrel restore device.

Description

technical field [0001] The invention mainly relates to a transmission device for switching industrial doors driven by motors and manually driven. Background technique [0002] The structure of the prior art is complex, and when switching between electric and manual, the clutch operation or chain hanging / chain removal must be carried out first, and the operation procedure is complicated and difficult to grasp. Contents of the invention [0003] Aiming at the defects of the above-mentioned prior art, the present invention provides an invention that is easy to operate. [0004] To achieve the above object, the technical solution of the present invention is: [0005] An automatic switchable transmission device for an industrial door opener, which includes a hand pull sprocket, a clutch device for a motor, a power switch and a support base, and is characterized in that it is provided with a bidirectional drive axial device installed on the support base ,it includes: [0006]...
