Description

Technical Field

[0001] This application relates to the technical field of elevators, and particularly relates to a counterweight frame structure with high stability. Background Art

[0002] The counterweight device is a component of the elevator traction system. It is installed in the elevator hoistway and is connected to the car through the traction rope via the traction wheel. During the movement of the elevator, the counterweight device slides up and down along the counterweight guide rail through the counterweight guide shoes, thereby balancing the weight of the car.

[0003] After retrieval, the patent with the Chinese patent authorization announcement number CN209974076U discloses an elevator counterweight frame, which includes an upper crossbeam, a lower crossbeam, and columns arranged between the upper crossbeam and the lower crossbeam. The upper crossbeam, the lower crossbeam, and the columns jointly enclose a support frame.

[0004] The elevator counterweight frame in the above patent has the following deficiencies: This device realizes fixation through the structure of the card slot and the protrusion. Although the counterweight blocks are effectively positioned in the horizontal direction, during use, the counterweight frame will move vertically, and there is no device on this device to limit the vertical direction of the counterweight blocks. Therefore, a good positioning effect is not exerted on the counterweight blocks, resulting in the phenomenon that the counterweight blocks will shake during movement. When the counterweight blocks shake, it will also cause the counterweight frame to shake along the direction of the guide rail, thus affecting the stability of the structure. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve or at least alleviate the problem in the prior art that there is no device on this device to limit the vertical direction of the counterweight blocks, so a good positioning effect is not exerted on the counterweight blocks, resulting in the phenomenon that the counterweight blocks will shake during movement. When the counterweight blocks shake, it will also cause the counterweight frame to shake along the direction of the guide rail, thus affecting the stability of the structure.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A counterweight frame structure with high stability, including a first horizontal plate, a second horizontal plate, two groups of counterweight blocks, and two vertical plates arranged on the first horizontal plate and the second horizontal plate. The first horizontal plate, the second horizontal plate, and the two vertical plates jointly enclose a frame. Guide grooves are opened on both of the two vertical plates. First partitions and second partitions are respectively fixedly installed on the outer walls of the first horizontal plate and the second horizontal plate close to each other. Limiting mechanisms are provided on both of the two counterweight blocks;

[0007] The limiting mechanism includes a first fixed seat and a second fixed seat. The first fixed seat is fixedly installed on one of the counterweights, and the second fixed seat is fixedly installed on the other counterweight. Two telescopic springs are symmetrically and fixedly installed on one outer wall of the first fixed seat. One end of each of the two telescopic springs is fixedly installed with the same push plate. A connecting column is fixedly installed on one outer wall of the push plate. The first fixed seat, the first partition plate, the second partition plate, and the second fixed seat are all provided with the same sliding groove. One end of the connecting column is rotatably installed with a rotating plate through a bearing.

[0008] Adopting the above technical solution, push the push plate to move. The movement of the push plate can drive the connecting column and the rotating plate to move accordingly. When the rotating plate moves to the outside of the sliding groove on the second fixed seat, the rotating plate can be rotated and then released at this time.

[0009] Optionally, the length of the rotating plate is greater than the width of the sliding groove.

[0010] Adopting the above technical solution, by setting that the length of the rotating plate is greater than the width of the sliding groove, the auxiliary installation function can be achieved.

[0011] Optionally, two limiting columns are fixedly installed through and on one outer wall of the rotating plate.

[0012] Adopting the above technical solution, the auxiliary limiting function can be achieved by setting the limiting columns.

[0018] Adopting the above technical solution, by setting the card slots and the clamping plates, the counterweights can be slidably installed while achieving the limiting effect in the horizontal direction.

[0019] Optionally, one end of each of the two counterweight blocks is slidably mounted on the outer walls of the first partition and the second partition close to each other, and the other ends of the two counterweight blocks are slidably mounted on the outer walls of the two vertical plates close to each other.

[0020] With the above technical solution, the first partition and the second partition are provided to play an auxiliary installation role.

[0021] Optionally, notches are formed through the top and bottom of the two vertical plates.

[0022] With the above technical solution, the notches are provided to facilitate the installation of the counterweight guide rail.
