Description

[0002] An elevator is a transportation device that transports pedestrians or goods vertically. When the elevator is in operation, it will occasionally fall. The elevator needs to be buffered and protected at the bottom, usually by buffer piles. The existing buffer piles are devices used for buffering and protecting the elevator when the elevator falls. The buffer piles are strengthened and fixed during installation, which is more stable and safe. The buffer piles are convenient for supporting and buffering the ends of the buffer plates during buffering, thereby improving the buffer piles' strengthening support and buffering effect on the elevator.

For this reason, the utility model proposes a buffer pile for an elevator. Utility Model Content

The bottom end of the buffer rod 104 is connected to the inner bottom end of the fixed column 106 by a buffer block 107. When the elevator falls, the bottom end of the elevator car directly hits the surface of the buffer plate 101. At this time, the main buffer spring 105 and the buffer block 107 are deformed and buffered to drive the buffer rod 104 to support the internal buffering of the fixed column 106, thereby providing buffer protection for the elevator. The buffer pile body 100 is also provided with:

[0025] A reinforced support and buffer mechanism is provided, and the reinforced support and buffer mechanism includes a fixed connection component and a reinforced support and buffer component. The fixed connection component is arranged at both ends of the upper surface of the fixed bottom plate 102, and the reinforced support and buffer component is arranged at the connection between the top side of the fixed connection component and the lower surface of the buffer plate 101. When the buffer pile body 100 is fixedly installed, when the elevator falls and buffers, the reinforced support and buffer mechanism performs reinforced support and buffer protection on both ends of the buffer plate 101. When the forces on both ends of the elevator fall are uneven, the end of the buffer plate 101 is still reinforced to buffer, and it is not easy to cause buffer damage to the buffer plate 101, thereby improving the reinforced support and buffer effect of the buffer pile body 100 on the elevator.

[0026] In order to facilitate the fixed installation of the support rod 1011 through the fixed connection assembly, and at the same time support the buffering operation of the end of the buffer plate 101 when the support rod 1011 is buffered, in this embodiment, preferably, the fixed connection assembly includes two columns 1012 fixedly installed on both ends of the upper surface of the fixed base plate 102 by bolts, and a slide groove 1016 is opened inside the column 1012, and a slide rod 1014 is fixedly installed inside the slide groove 1016.

The top of the support rod 1011 is embedded in the interior of the buffer plate 101, and the two support rods 1011 are symmetrically arranged. The support rod 1011 is convenient for strengthening the support and buffering of the two ends of the lower surface of the buffer plate 101 during buffering. When the elevator falls and the forces on both ends are uneven, the buffering of the end of the buffer plate 101 is still strengthened, and it is not easy to cause buffering damage to the buffer plate 101.

[0028] A reinforcing fixing mechanism is provided, and the reinforcing fixing mechanism includes a reinforcing fixing component and a screw-in adjustment component. The reinforcing fixing component is arranged at the bottom end of the mounting hole 103 and is located inside the fixed bottom plate 102. The screw-in adjustment component is arranged at the end of the reinforcing fixing component. When the buffer pile body 100 is fixedly installed before use, the reinforcing fixing mechanism can strengthen the fixed installation of the bolt rotating inside the mounting hole 103, thereby reinforcing the installation and use of the buffer pile body 100, and the fixed installation is more stable and safe for buffer protection, thereby improving the fixation of the buffer pile body 100 for elevator buffer protection.

[0029] In order to facilitate the bolt to penetrate the interior of the mounting hole 103 and strengthen the fixed installation by strengthening the fixing assembly, in this embodiment, preferably, the strengthening fixing assembly includes a mounting groove 1032 opened at the bottom end of the mounting hole 103 and located inside the fixed base plate 102, and flexible pull plates 1033 are fixedly installed on both sides of the interior of the mounting groove 1032 by screws, and an anti-slip splint 1037 is welded and fixed to the inner surface of the flexible pull plate 1033, and the flexible pull plate 1033 and the anti-slip splint 1037 can be pulled inside the mounting groove 1032 until the inner surface of the anti-slip splint 1037 is squeezed against the surface of the bolt for reinforced installation.

[0030] In order to facilitate the surface reinforcement installation of the flexible pull plate 1033 and the anti-slip clamp 1037 tightening bolts by screwing in the adjustment component, in this embodiment, preferably, the screw-in adjustment component includes an adjustment slot 1031 opened on the side of the fixed base plate 102, and the interior of the adjustment slot 1031 is rotatably connected with a threaded rod 1034, one end of the threaded rod 1034 is fixedly connected to the end of the flexible pull plate 1033 by welding, and the other end of the threaded rod 1034 is rotatably connected with a screw-in nut 1036, which is convenient for the interior of the adjustment slot 1031 to be adjusted. The screw-in nut 1036 is rotated on the outer surface of the threaded rod 1034, and the threaded rod 1034 and the flexible pull plate 1033 are pulled by rotating the screw-in nut 1036, which facilitates the screw-in adjustment operation. The outer surface of the threaded rod 1034 is located on one side of the screw-in nut 1036 and a reinforcement nut 1035 is rotatably installed. The reinforcement nut 1035 has the same structure as the screw-in nut 1036. After the screw-in adjustment is fixed, the reinforcement nut 1035 is rotated again to squeeze the surface of the screw-in nut 1036 to strengthen and fix it, making the installation more secure.

[0031] Working principle and use process of the utility model: before using the buffer pile for the elevator, firstly, the buffer pile body 100 is placed at the inner bottom end of the elevator shaft through the fixed bottom plate 102, and the bolts are passed through the inside of the mounting hole 103 to fix the buffer pile body 100 at the position where it is installed on the ground. When the buffer pile body 100 is fixedly installed and used, when the elevator falls, the bottom end of the elevator car directly hits the surface of the buffer plate 101, at this time, the main buffer spring 105 and the buffer block 107 are deformed and buffered to drive the buffer rod 104 to buffer the internal support of the fixed column 106, thereby providing buffer protection for the elevator;

[0032] Then, when the buffer pile body 100 is installed and the elevator falls to provide buffer protection at the middle position, the elevator falls and hits the surface of the buffer plate 101. At the same time, the two ends of the lower surface of the buffer plate 101 are impacted and drive the support rod 1011 and the slider 1013 to slide on the outer surface of the slide rod 1014. At the same time, the auxiliary buffer spring 1015 is deformed to buffer and support the slider 1013 and the support rod 1011, so that the support rod 1011 is used to strengthen the support and buffering of the two ends of the lower surface of the buffer plate 101. When the forces on the two ends of the elevator are uneven, the buffering of the end of the buffer plate 101 is still strengthened, and it is not easy to cause the buffering damage of the buffer plate 101, thereby improving the strengthening support and buffering effect of the buffer pile body 100 on the elevator.

[0033] Finally, before the buffer pile body 100 is installed and used, the bolt passes through the interior of the mounting hole 103 and rotates to fix the buffer pile body 100. At this time, the nut 1036 can be rotated and screwed into the outer surface of the threaded rod 1034 inside the adjusting groove 1031. The rotating screw-in nut 1036 drives the threaded rod 1034 to be screwed in and adjusted. When the threaded rod 1034 is screwed in, the flexible pull plate 1033 is pulled until the anti-slip clamp plate 1037 is squeezed and fixed on one side of the bolt for reinforcement installation. After fixed installation, the reinforcement nut 1035 is rotated again to strengthen the fixation of the threaded rod 1034 and the flexible pull plate 1033, and the other side surface of the bolt is reinforced again, so that the bolt and the fixed base plate 102 are fixed and installed, so that the buffer pile body 100 is reinforced and installed for use. When the buffer pile body 100 is used for elevator buffer protection, the buffer pile body 100 is not easy to cause the bolt and the buffer pile body 100 to loosen when it is hit, and the fixed installation is more stable and safe buffer protection, which improves the fixity of the buffer pile body 100 for elevator buffer protection.
