Embodiment Construction

[0010] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] see Figure 1-3 As shown, a rotary car top guardrail includes a pair of vertical bars 1, a pair of movable bars 3, a first cross bar 2, a second cross bar 4, a limit switch (not shown in the figure), a locking mechanism (not shown), the figure 1 Among them, a pair of vertical bars 1 are arranged at intervals from left to right. Similarly, a pair of movable bars 3 are also arranged at intervals from left to right. The bottoms of a pair of vertical bars 1 are fixed on the car roof, and the tops of a pair of vertical bars 1 are fixedly arranged. There is a first cross bar 2, a second cross bar 4 is arranged parallel to the first cross bar 2, a chute 5 extending along the length direction of the bar is opened on the second cross bar 4, and one end corresponding to a pair of movable bars 3 Department (such as figure 1 and 2 The lower end...

Abstract

The invention discloses a rotary car top guard. A vertical rod and a movable rod are arranged separately with one being above the other, so that the movable rod of the guard can rotate to drive a second cross rod to be folded to be coincident with a first cross rod, so that the height of the guard is lowered and the guard can be adapted to the condition that the space between a car top and a host is small when a machine-room-less elevator stops at a top floor and meets the arrangement condition that the space above the car top is small without influencing normal operation of a car. The movable rod of the guard can be opened to reach the place above the vertical rod through rotation, thus the height of the guard is increased to meet the requirement on the height of the guard in the standard; and a limit switch inhibits the elevator car from operating, thus the safety of a worker carrying out overhaul or other operations at the elevator car top is ensured.

Description

technical field [0001] The invention relates to a car top guardrail, in particular to a rotary car top guardrail. Background technique [0002] In the prior art, in order to ensure the safety of the staff performing maintenance or other operations on the elevator car top, the height of the car top guardrail must meet certain requirements, but such a height of the car top guardrail will make it impossible to adapt to machine room-less elevators stopping on the top floor. When the distance between the car roof and the main engine is too small. Contents of the invention [0003] The purpose of the present invention is to provide a rotating car top guardrail. When the elevator is in normal operation, the car top guardrail will be retracted in the height direction, so as to adapt to the small distance between the car top and the main engine when the machine room-less elevator stops on the top floor. However, when it is necessary to perform maintenance or other operations on th...
