Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 in conjunction with fig. 2-6, an embodiment of the present invention includes:
a padlock device for a main power switch of an elevator is arranged on a panel 2 of a main power box 1 and corresponds to an operating handle 4 of the main power switch 3, and comprises a fixed lock plate 5, a guide column 6, a movable lock plate 7 and a spring 8.
A rectangular hole 9 is formed in the panel 2, and the operating handle 4 of the main power switch 3 is arranged corresponding to the rectangular hole 9 so as to be convenient for operating the operating handle 4 of the main power switch 3.
The fixed locking plate 5 is arranged on one side of the edge of the rectangular hole 9 on the front surface of the panel 2 and is transversely provided with a fixed locking hole 10 for playing a fixed positioning role.
The guide posts 6 are transversely provided with two guide grooves 11 which are arranged on one side of the back of the panel 2 in a vertically corresponding mode, the movable locking plate 7 is longitudinally and horizontally provided with two guide grooves 11 which are arranged in a sliding mode and correspond to the two guide posts 6 respectively, and therefore the guide grooves 11 of the movable locking plate 7 can move up and down directionally along the two guide posts 6.
The inboard end of guide post 6 is the cylindrical structure setting, and outside end surface is provided with the screw thread, remove jam plate 7 and set up in the inboard end of guide post 6 and through the nut 12 locking of outside end threaded connection. The movable locking plate 7 is convenient to move, adjust and arrange by loosening and tightening the nut 12.
And a limiting strip 13 positioned above the operating handle 4 of the main power switch 3 is transversely and convexly arranged on one side of the movable locking plate 7 so as to realize synchronous up-and-down motion of the movable locking plate 7 and the operating handle 4 of the main power switch 3.
The positive border protrusion of removal jam plate 7 is provided with the removal locating plate 14 parallel with fixed jam plate 5, be provided with the removal lockhole 15 that corresponds with fixed lockhole 10 on the removal locating plate 14, when the elevator under the maintenance state, remove lockhole 15 and fixed lockhole 10 and flush the correspondence to make things convenient for the padlock to pass the locking that realizes removing jam plate 7, at this moment, spacing 13 blocks main switch 3's operating handle 4, makes it unable action.
