Embodiment 1

[0018] see figure 1 , is a cross-sectional view of an embodiment of the automatic retractable safety guardrail for an elevator provided by the present invention.

[0019] The automatic retractable safety guardrail 1 for the elevator includes four columns 11 , a box frame 12 , a guardrail 13 , a lifting mechanism 14 and a block 15 .

[0020] The column 11 includes a column body 111 , a frame guide rail 112 and a guardrail guide rail 113 . The frame guide rail 112 is arranged on the inner side of the column body 111 , and the guardrail guide rail 113 is arranged on the outer side of the column body 111 .

[0021] The box frame 12 includes a box frame body 121 and a box frame guide shoe 122 . The frame guide shoe 122 is disposed outside the frame body 121 .

[0022] The guardrail 13 includes a guardrail body 131 and a guardrail guide shoe 132 . The guardrail guide shoe 132 is disposed outside the guardrail body 131 .

[0023] The four column bodies 111 are arranged verticall...

Embodiment 2

[0026] see figure 2 , is a cross-sectional view of another embodiment of the automatic retractable safety barrier for elevators provided by the present invention.

[0027] The automatically retractable safety guardrail 1 for the elevator in this embodiment is consistent with the structure in Embodiment 1 and will not be described in detail here.

[0028] The lifting mechanism 14 can also be a scissor-type lifting mechanism, which is arranged at the bottom of the column body 111 and connected to the bottom of the box body 121 .

[0029] During specific implementation, the lifting mechanism 14 is activated to push the frame body 121 to move upward. The top of the box frame body 121 is in contact with the stopper 15, driving the guardrail body 131 to move upwards, realizing the automatic opening of the guardrail. Similarly, when the frame body 121 moves down, the guardrail body 131 moves down synchronously and closes under the action of gravity.

Abstract

The invention provides an automatic folding and unfolding safety fence for a lifting machine. The automatic folding and unfolding safety fence for the lifting machine comprises a plurality of stand columns, a carriage frame and a lifting mechanism. The multiple stand columns are vertically arranged. The carriage frame is arranged among the stand columns. The lifting mechanism is connected with the carriage frame. The automatic folding and unfolding safety fence further comprises a fence body and stop blocks. Each stand column comprises a stand column body and a fence guide rail, wherein the fence guide rail is arranged on the outer side of the stand column body. The fence body comprises a main fence body and a fence guide shoe which is arranged on the outer side of the main fence body and abuts against the fence guide rails. The stop blocks are arranged on the side, close to the carriage frame, of the main guide rail body. The automatic folding and unfolding safety fence for the lifting machine solves the technical problems that a fence in the prior art is complex in opening and closing operation, and an automatic opening and closing system is high in cost and unstable in running.

Description

technical field [0001] The invention relates to the field of safety guardrails, in particular to an automatically retractable safety guardrail for an elevator. Background technique [0002] In the process of industrial production, it is often necessary to use elevators to transfer materials or equipment between high floors and low floors. Most of the high-level platforms are designed with guardrails to prevent people or objects from falling. However, every time the elevator reaches a high level, it needs to perform an operation to open the guardrail, and every time it descends, it needs to perform an operation to close the guardrail. Not only does it seriously slow down the transportation and production efficiency, but also because of the cumbersome operation, it is easy to cause accidents due to forgetting to close the guardrail. In order to solve this problem, many lifts are designed with automatic opening and closing systems for guardrails. However, most of the guardra...
