Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator counterweight protection component. Background Art

[0002] The elevator counterweight is a method of maintaining a balance between the weight of the car and the effective load part. After searching, the patent with the announcement number CN218491235U discloses an elevator counterweight protection assembly, which is installed in the elevator shaft and is used to protect the counterweight assembly of the elevator; the elevator counterweight protection assembly includes a main body, and the main body has a protection chamber, and the protection chamber is used to accommodate the counterweight assembly, and the main body extends from the bottom pit of the elevator shaft to the top floor of the elevator shaft. The advantage is that the elevator counterweight protection assembly can completely wrap the counterweight assembly from bottom to top, no matter where the counterweight assembly runs to, it is in the elevator counterweight protection assembly. When the installation or maintenance personnel are working on the middle floor, there is an elevator counterweight protection assembly between the counterweight assembly and the staff, ensuring the safety of the staff. However, when the elevator counterweight moves up and down, it slides against the side walls of the guide roller. As a result, when the elevator counterweight falls, it cannot be buffered and decelerated, reducing the safety of the elevator counterweight. At the same time, the counterweight components are composed of individual counterweight blocks stacked and fitted together, which results in the counterweight block at a specified position not being able to be removed during subsequent disassembly and maintenance of the internal counterweight blocks due to the limiting devices on both sides of the counterweight blocks.

A card slot 16 is provided, the width of the card slot 16 matches the diameter of the card rod 17, and the card slot 16 is slidably connected to the card rod 17. The overall mounting frame 2 is in a "mouth" shape, and the upper end of the card rod 17 is fixedly connected to the top surface inside the mounting frame 2. The front end side wall of the counterweight block 3 protrudes from the front end side wall of the mounting frame 2 to the outside. When the mounting frame 2 equipped with the counterweight block 3 moves up and down, under the action of the gravity of the counterweight block 3, the buffer block 4 can be conveniently squeezed so that the buffer block 4 is squeezed into the interior of the moving groove 14, so that when the counterweight block 3 fails and falls, the mounting frame 2 can continuously squeeze the buffer block 4 during the descent process, which can effectively slow down the descent speed of the mounting frame equipped with the counterweight block 3.

[0022] Example 2

[0023] In this embodiment, Figure 1-5 As shown, the guide rail 1 is provided with a first baffle 6 and a second baffle 7, and both side walls of the first baffle 6 are fixedly installed with support rods 5, and the ends of the support rods 5 are fixedly connected to the side walls of the guide rail 1. A second connecting groove 13 is provided in the front end side wall at the bottom of the first baffle 6, and a first connecting groove 12 is provided inside the front end side wall below the guide rail 1. The first baffle 6 is arranged between the second baffle 7 and the bottom surface of the guide rail 1, and connecting blocks 8 are fixedly installed at both ends of the upper end of the first baffle 6, and the connecting blocks 8 are slidably connected to the inside of the first connecting groove 12 and the second connecting groove 13 through the second baffle 7, and bolts 15 are symmetrically installed inside the connecting block 8, and The bolts 15 at both ends are respectively connected to the side walls of the first connecting groove 12 and the second connecting groove 13 through the internal threads of the second baffle plate 7. The side walls of the first baffle plate 6 and the second baffle plate 7 are both in contact with the front end side walls of the counterweight 3. The height of the mounting frame 2 is equal to the distance from the bottom of the first baffle plate 6 to the bottom of the guide rail 1. The side walls of the first baffle plate 6 and the second baffle plate 7 are both horizontal. When installing or disassembling the counterweight 3, the second baffle plate 7 is disassembled. At this time, the top of the mounting frame 2 is below the first baffle plate 6, and the front end side wall of the counterweight 3 loses the limiting device, so the counterweight 3 to be disassembled can be easily pulled out from the inside of the mounting frame 2.

[0024] Example 3

[0025] In this embodiment, Figure 1-5 As shown, a support seat 9 is provided below the mounting frame 2, and a buffer spring 11 is fixedly installed at an equal interval between the upper end of the support seat 9 and the lower end side wall of the mounting frame 2, and a limit rod 10 is symmetrically fixedly installed at both ends of the top surface of the support seat 9, and the upper ends of the limit rods 10 are both inserted into the inside of the side walls at both ends of the mounting frame 2, and are respectively slidably connected to the inside of the side walls of the mounting frame 2. When the mounting frame 2 moves downward, the support seat 9 can first contact with the bottom of the guide rail 1, and then the bottom of the mounting frame 2 will squeeze the buffer spring 11, and the force of the buffer spring 11 can further slow down the downward movement of the mounting frame 2.

[0026] It should be noted that in this embodiment, when the elevator counterweight protection assembly is used, Figure 1-5 As shown, when the counterweight 3 is installed or disassembled, the second baffle 7 is disassembled. At this time, the top of the mounting frame 2 is below the first baffle 6, and the front end side wall of the counterweight 3 has lost the limiting device. The counterweight 3 to be disassembled can be easily pulled out from the inside of the mounting frame 2. When the mounting frame 2 equipped with the counterweight 3 moves up and down, under the action of the gravity of the counterweight 3, the buffer block 4 can be easily squeezed so that the buffer block 4 is squeezed into the inside of the moving groove 14. Therefore, when the counterweight 3 fails and falls, the mounting frame 2 can continuously squeeze the buffer block 4 during the descent process, which can effectively slow down the descent speed of the mounting frame equipped with the counterweight 3. At the same time, when the mounting frame 2 moves to the bottom of the guide rail 1, the support seat 9 can first contact the bottom of the guide rail 1, and then the bottom of the mounting frame 2 will squeeze the buffer spring 11. Through the force of the buffer spring 11, the force of the downward movement of the mounting frame 2 can be further slowed down, thereby enhancing the safety of the use of the counterweight 3.
