Embodiment Construction

[0019] Such as figure 1 , figure 2 As shown, when the guide arm 4 slides and rotates along the tooth surface of the ring gear, when the guide arm moves upwards, the corresponding tooth surface is the upward segment, and when the guide arm moves downward, the corresponding tooth surface is the downward segment.

[0020] In the long-distance and short-distance double-controlled mutual control power supply master switch of the present invention, two poles of the power supply are arranged in the seat body, and the two poles of the power supply are controlled to be turned on or off by the contact arm 12, and the upper and lower sides of the contact arm 12 are respectively pressed together with an upper spring 10 and a Lower spring 14, the elastic coefficient of upper spring 10 is greater than the elastic coefficient of lower spring 14, the upper end of upper spring 10 is suppressed by contact rod 8, upper spring 10 is suppressed by electromagnetic coil 7 at the same time, the top ...

Abstract

The invention discloses a remote short-range double-control mutual-control power supply main switch. A contact arm controls on and off of a power supply. The contact arm controls the on and off of two poles of the power supply. An upper spring and a lower spring are respectively stitched on the up and down of the contact arm. An elastic coefficient of the upper spring is greater than the elastic coefficient of the lower spring. An upper end of the upper spring is pressed by a contact rod and the upper spring is simultaneously pressed by an electromagnetic coil. A guide assembly, which is arranged above the contact rod, comprises: a guide bar and a guide arm. The guide bar is hand-operated or is driven by the electromagnetic coil. The guide bar presses against with the contact rod. The guide arm is fixedly connected with the guide bar. The guide arm is arranged between a pair of gear rings which are arranged up and down. The gear rings are fixed on a seat body. As long as the contact rod moves once, no matter an electromagnetic force or a manual force, the guide bar 2 can rotate and adjust to a tooth root position of the next upper arc gear ring so that the contact rod can turns on or disconnect two electrodes. The switch is suitable for operating and controlling a large-scale engineering machinery with a long distance.

Description

technical field [0001] The invention relates to the technical field of safety control of the total power supply of engineering machinery. Background technique [0002] Most of the main power switches of construction machinery are purely mechanical or manual. In the application of large construction machinery, the operator's control position is generally far away from the ground, so it will be inconvenient and inconvenient to use any kind of power switch. safety factor. Contents of the invention [0003] The technical problem solved by the present invention is to provide a long-range and short-range dual-control and mutual-control power supply main switch, which can realize both long-distance and short-distance control. [0004] The technical scheme adopted in the present invention is that the long-distance and short-distance dual-control mutual control power supply master switch is provided with two poles of the power supply in the seat, and the two poles of the power sup...
