Description

Technical Field

[0001] This utility model relates to the field of buffer technology, specifically a buffer for elevator shaft protection. Background Technology

[0002] Elevator shaft buffers are a component of elevator safety systems. They are primarily used to absorb impact energy when an elevator malfunctions, such as when a wire rope breaks, traction fails, or the control system malfunctions. This prevents the car or counterweight from directly impacting the bottom or top of the shaft, ensuring the safety of passengers and equipment. When an elevator falls at excessive speed or overshoots the top due to a malfunction, the buffer dissipates energy through physical or hydraulic mechanisms, bringing the car or counterweight to a smooth stop and avoiding violent collisions.

[0003] When using existing elevator shaft protection buffers, their function is to absorb impact energy when the elevator goes out of control, preventing the elevator from falling violently due to malfunction and excessive speed. In existing buffers, the two ends of the guide rod are welded to the support pile and the buffer rod on one side, which cannot be separated, resulting in the problem that the support pile and buffer rod cannot be disassembled for maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a buffer for elevator shaft protection, so as to solve the problem mentioned in the background art that the two ends of the guide rod of the existing buffer are welded to the surface of the support pile and the buffer rod, which cannot be separated, thus making it impossible to separate and maintain the support pile and the buffer rod.

[0011] Preferably, an adjustment mechanism is sleeved on the outer wall of the bottom end of the guide rod. The adjustment mechanism includes a fixing frame. A second screw is inserted inside one side of the guide rod. One end of the second screw is connected to a limit ring. One end of the limit ring is connected to a third screw. A second nut is rotatably connected to the outer surface of one end of the third screw.

[0012] Preferably, a threaded hole is provided at the bottom of one side of the guide rod, and one end of the second screw is rotatably connected to the threaded hole provided in the guide rod.

[0013] Preferably, the fixing frame is connected to one side surface of the support pile, and a through groove is opened on one side of the fixing frame. The third screw is inserted into the through groove of the fixing frame, and the second nut is rotatably connected to the outer surface of one end of the third screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The buffer rod and the movable plate are hinged together by a fixed rod. The movable plate can be stored in the groove of the buffer rod. When installing the guide rod, the angle of the movable plate is adjusted, and the positioning stake connected to the top of the guide rod is inserted into the positioning groove of the movable plate to position the movable plate. The first screw is then inserted into the through hole of the movable plate, and the first nut is rotated to connect to the outer surface of the top of the first screw to limit the first screw. This realizes the assembly function between the buffer rod and the guide rod, avoiding the problem that the support stake and buffer rod cannot be disassembled and maintained because the guide rod cannot be disassembled.

[0016] 2. By rotating the second screw into the threaded hole of the guide rod, inserting the bottom end of the guide rod into the fixed frame, and inserting the third screw into the through groove of the fixed frame, the limiting ring is used to separate the guide rod and the fixed frame, reducing friction between them.
