Abstract

The invention discloses a flatly-rotated car top guard which is provided with a first vertical rod and a second vertical rod at an upper section and a lower section, wherein the second vertical rod of the guard can be overturned to be under a first cross rod by means of flat rotation (quadrilateral linkage), and the height of the guard can be reduced, so that the situation that the distance between a car top and a host machine is smaller when the elevator without a machine room stops at the top floor can be met, therefore, the distribution situation with a smaller space above the car top can be met, and the normal running of the car platform sill can not be influenced. The second vertical rod of the guard can be further overturned to be above the first vertical rod by means of flat rotation, so that the height of the guard can be increased, the requirement of the standard on the height of the guard can be met, and the safety can be guaranteed when the overhaul or other operations are carried out on the elevator car roof by workers.

Description

[0001] technical field

[0002] The invention relates to a car top guardrail, in particular to a car top guardrail with a flat rotation.

[0003] Background technique

[0004] 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.

[0005] Contents of the invention

[0006] The purpose of the present invention is to provide a horizontally rotating car top guardrail. When the elevator is running normally, the car top guardrail will be retracted in the height direction, so as to adapt to the situation that the distance between the car top and the main engine is relatively small when the machine room-less elevator stops on the top ...

Examples

Embodiment Construction

[0016] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] see Figure 1-3 As shown, a car top guardrail with flat rotation includes a pair of first vertical bars 1, a pair of second vertical bars 2, a first cross bar 3, a second cross bar 4, and a limit switch (not shown in the figure) , locking mechanism 9, in figure 1 Among them, a pair of first vertical rods 1 are arranged at intervals from left to right. Similarly, a pair of second vertical rods 2 are also arranged at intervals from left to right. The bottoms of a pair of first vertical rods 1 are fixed on the car roof. A first horizontal bar 3 is fixedly arranged between the tops of the bars 1, and one end corresponding to a pair of second vertical bars 2 (such as figure 1 and 2 in the lower end or as in image 3 The upper end of the middle) and the top of a pair of first vertical bars 1 or the two ends of the first cross bar 3 are rotated thr...
