Embodiment 1

[0017] Example 1: Such as figure 1 Shown, a kind of elevator car lifting safety cross bar, comprises car 1, cross bar 2, is characterized in that: described cross bar 2 is arranged in car 1, and can move out from car 1 to each floor elevator Below the door frame of the entrance.

Embodiment 2

[0018] Example 2 :Such as figure 1 As shown, an elevator car lifting safety cross bar includes a car 1, a cross bar 2, and a floor fixing member 3, and is characterized in that: the cross bar 2 is arranged in the car 1 and can be removed from the car 1 Below the door frame of the elevator entrance and exit on each floor; the crossbar 2 has a corresponding floor fixing part 3, the height of the upper end of the floor fixing part 3 is the same as the height of the crossbar 2, and the floor fixing part 3 is installed on the elevator door of each floor above the door.

Embodiment 3

[0019] Example 3 :Such as figure 1 As shown, an elevator car lifting safety cross bar includes a car 1, a cross bar 2, a floor fixing member 3, a fixing slot 4, and an electromagnet 5. It is characterized in that: the cross bar 2 is arranged on the car 1 Among them, the cross bar 2 is made of iron, and can be moved out from the car 1 to below the door frame of the elevator entrance on each floor; The height of bar 2 is identical, and floor fixture 3 is installed on the top of each floor elevator door doorway; Electromagnet 5 is installed at described fixed slot position 4 tail ends, and cross bar 2 is made of iron, and spring is installed at cross bar 2 tail ends. When the elevator goes up and down, the electromagnet 5 is energized, and the crossbar 2 is attracted back to the inside of the car; The elevator car accidentally went up and down out of control.

Abstract

The invention relates to a lifting safety cross rod of an elevator lift car. The lifting safety cross rod comprises the lift car 1 and the cross rod body 2. The lifting safety cross rod is characterized in that the cross rod body 2 is arranged in the lift car 1 and can move out of the lift car 1 to be located below a door frame of an inlet and outlet of every floor of elevator. According to the lifting safety cross rod of the elevator lift car, the structure is simple and the manufacturing cost is low; the condition that the elevator lift car is accidentally out of control to ascend and descend can be prevented; the problem of casualties due to the fact that the existing elevator lift car is accidentally out of control to ascend and descend is solved.

Description

technical field [0001] The invention relates to an elevator car lifting safety cross bar, in particular to an elevator car lifting safety cross bar with the function of protecting the safety of the elevator car occupants. Background technique [0002] The existing elevator car is not provided with a lifting safety crossbar for protecting the safety function of the occupants. If the car is accidentally lifted and lowered, the occupants will be stuck and cause casualties. On February 08, 2009, a freight elevator in a restaurant in Shapingba District, Chongqing suddenly had an accident. Sincerely.
