Description

Technical Field

[0001] The present application relates to the field of elevator installation, and in particular, to an elevator shaft protection structure. Background Art

[0002] The elevator shaft is the passage where the elevator is installed. The size of the shaft is determined according to the type of elevator selected. Elevator tracks and counterweight tracks are installed on the shaft wall. Door openings are reserved on the side walls of the shaft for installing elevator doors. There is an elevator machine room on the top of the shaft. During and before the installation of the elevator, protective fences are required to isolate and protect the reserved elevator door openings to prevent people from falling into the elevator shaft. However, in related protective fence technologies, the structure of the protective fence is relatively fixed and has poor structural flexibility. During the installation of the elevator, when the installers need to temporarily use the elevator door opening, they need to move the entire protective fence before using the elevator door opening. After the temporary use is completed, the entire protective fence needs to be moved to enclose the elevator door opening, which is more laborious and inconvenient. Utility Model Content

[0003] In order to make up for the above shortcomings, the present application provides an elevator shaft protection structure, which aims to improve the problem that the entire protective fence needs to be moved when the elevator door opening is temporarily used, which is relatively laborious and inconvenient.

[0004] An embodiment of the present application provides an elevator shaft protection structure, including a protective fence.

[0005] The protective fence includes a base plate, a connecting frame, a rotating shaft, a limiting rod, an elastic member and a guardrail. The connecting frame is connected to the base plate, the bottom end of the rotating shaft is rotatably connected to the base plate, the top end of the rotating shaft is rotatably connected to the connecting frame, the cross-section of the limiting rod is polygonal, the bottom end of the limiting rod is slidably inserted into the interior of the rotating shaft, the rod body of the limiting rod slides through the top end of the connecting frame, the bottom end of the elastic member is connected to the top end of the connecting frame, the top end of the elastic member is connected to the top end of the limiting rod, and the guardrail is fixedly connected to the shaft body of the rotating shaft.

[0006] In a specific embodiment, both side corners of the upper surface of the bottom plate are configured to be arc-shaped.

[0007] In a specific embodiment, a first connecting sleeve is provided on the upper surface of the bottom plate, and the bottom end of the rotating shaft is rotatably inserted into the interior of the first connecting sleeve.

[0008] In a specific embodiment, the connecting frame is configured to be L-shaped, and the bottom end of the connecting frame is fixedly connected to the upper surface of the bottom plate.

[0009] In a specific embodiment, a second connecting sleeve is provided on the lower surface of the top wall of the connecting frame, and the top end of the rotating shaft is rotatably inserted into the interior of the second connecting sleeve.

[0010] In a specific embodiment, the cross section of the limiting rod is rectangular, a limiting slot is provided at the center of the top end of the rotating shaft, the cross section of the limiting slot is rectangular, and the limiting rod is slidably inserted into the interior of the limiting slot.

[0011] In a specific embodiment, a pull plate is provided at the top end of the limiting rod, and the top end of the elastic member is fixedly connected to the lower surface of the pull plate.

[0012] In a specific embodiment, the elastic member is slidably sleeved on the rod body of the limiting rod, and the elastic member is a spring.

[0013] In a specific embodiment, the guardrail is located above the bottom plate, and buffer pads are provided on both sides of the guardrail.

[0014] When the hoistway elevator door opening needs to be temporarily used, the limit rod is pulled upward to rotate the guardrail, and the hoistway elevator door opening can be used. The limit rod is reinserted into the rotating shaft to fix the guardrail, and there is no need to move the entire guardrail, which is more labor-saving and convenient.

[0024] See also Figure 1 , the present application provides an elevator shaft protection structure, including a protective fence 100.

[0025] See also Figure 1-5 The protective fence 100 includes a base plate 110, a connecting frame 120, a rotating shaft 130, a limiting rod 140, an elastic member 150 and a guardrail 160. The corners on both sides of the upper surface of the base plate 110 are set to be arc-shaped. The connecting frame 120 is connected to the base plate 110. The connecting frame 120 is set to be L-shaped, and the bottom end of the connecting frame 120 is fixedly connected to the upper surface of the base plate 110.

[0026] In this embodiment, the bottom end of the rotating shaft 130 is rotatably connected to the base plate 110, and a first connecting sleeve 111 is provided on the upper surface of the base plate 110. The bottom end of the rotating shaft 130 is rotatably inserted into the interior of the first connecting sleeve 111. The top end of the rotating shaft 130 is rotatably connected to the connecting frame 120. A second connecting sleeve 121 is provided on the lower surface of the top wall of the connecting frame 120, and the top end of the rotating shaft 130 is rotatably inserted into the interior of the second connecting sleeve 121.

[0027] In the present application, the cross-section of the limiting rod 140 is polygonal, the bottom end of the limiting rod 140 is slidably inserted into the inside of the rotating shaft 130, the cross-section of the limiting rod 140 is rectangular, and a limiting groove 131 is opened in the center of the top of the rotating shaft 130. The cross-section of the limiting groove 131 is rectangular, and the limiting rod 140 is slidably inserted into the inside of the limiting groove 131. The rod body of the limiting rod 140 slides through the top of the connecting frame 120.

[0028] In this embodiment, the bottom end of the elastic member 150 is connected to the top of the connecting frame 120, and the top of the elastic member 150 is connected to the top of the limiting rod 140. A pull plate 141 is provided at the top of the limiting rod 140. The top of the elastic member 150 is fixedly connected to the lower surface of the pull plate 141. The elastic member 150 is slidably sleeved on the rod body of the limiting rod 140, and the elastic member 150 is a spring.

[0029] In a specific configuration, the guardrail 160 is fixedly connected to the shaft of the rotating shaft 130 . The guardrail 160 is located above the bottom plate 110 . Buffer pads 161 are provided on both sides of the guardrail 160 .

[0030] Specifically, the working principle of the elevator shaft protection structure is as follows: when in use, the bottom plate 110 can be placed on one side of the hoistway elevator door opening, and the guardrail 160 can isolate and block the hoistway elevator door opening for protection. When the elevator installer needs to temporarily use the hoistway elevator door opening, he pulls the pull plate 141 upward. When the pull plate 141 moves upward, it drives the limit rod 140 to move upward. The pull plate 141 stretches the elastic member 150, and the limit rod 140 can be pulled out of the limit groove 131, and then the guardrail 160 can be pushed to rotate, so that the guardrail 160 no longer blocks the hoistway elevator door opening, and then the hoistway elevator can be used. After the use of the elevator door opening and the hoistway elevator door opening is completed, the guardrail 160 is rotated and reset, and the limiting rod 140 re-enters the limiting groove 131, and then the rotating shaft 130 and the guardrail 160 are re-fixed, so that the guardrail 160 can isolate and block the hoistway elevator door opening again. When the hoistway elevator door opening needs to be used temporarily, the limiting rod 140 can be pulled upward to rotate the guardrail 160, and then the hoistway elevator door opening can be used. The limiting rod 140 is re-inserted into the rotating shaft 130 to fix the guardrail 160, and there is no need to move the entire protective fence 100, which is more labor-saving and convenient.
