Abstract
Description
Technical Field
[0001] This application relates to the technical field of balance adjustment devices, and in particular to an elevator car balance adjustment device. Background Technology
[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° from the vertical. Its working principle is that the car and the counterweight are connected to the two ends of the traction rope, which is wound around the traction sheave and the guide sheave. The traction motor drives the traction sheave to rotate after the speed is reduced by the speed reducer. The traction force generated by the friction between the traction rope and the traction sheave realizes the lifting and lowering movement of the car and the counterweight to achieve the transportation purpose.
[0003] A search revealed Chinese Patent Publication No. CN214828252U, which discloses an elevator car balancing device. Addressing the problem that existing elevator car balancing adjustments are complex and reduce installation efficiency, this invention proposes the following solution: It includes an elevator car body and a counterweight plate. A balancing plate is fixedly installed at the bottom of the elevator car body. One side of the balancing plate has a through hole, and the bottom of the balancing plate has multiple insertion slots. A connecting plate is fixedly installed at the top of the counterweight plate, and the connecting plate is movably inserted into the corresponding insertion slot. The bottom of the connecting plate has a vertical groove, within which two sliding plates are interactively installed. Each of the two sliding plates has a locking plate installed on its opposite side, and both locking plates are engaged within the through hole. This invention achieves rapid and efficient balancing adjustment of the elevator car by quickly installing and removing the counterweight plate, thus improving work efficiency.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The above-mentioned solutions achieve rapid and efficient balance adjustment of the elevator car by quickly installing and removing the counterweight plate on the elevator car, thereby improving work efficiency and reliability. However, this device cannot quickly install the counterweight block, nor can it strengthen the fixing device of the counterweight block, which can easily cause the counterweight block to loosen or fall off during movement.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.
[0022] This application discloses an elevator car balance adjustment device. For example... Figure 1 , Figure 3 , Figure 4 As shown, the device includes a body 1, and the interior of the body 1 is provided with several connecting frames 7. Each connecting frame 7 has two first springs 10 fixedly connected to its inner wall. Each first spring 10 has a plug rod 12 fixedly connected to one end near the corresponding slide groove 5. The outer surface of each plug rod 12 is inserted into the corresponding first slot 6. Multiple connecting frames 7 are provided. By pushing the plug rod 12, the plug rod 12 will slide horizontally along the corresponding connecting frame 7. At this time, the corresponding first spring 10 will be compressed. Without the action of external force, the first spring 10 will push the corresponding plug rod 12 to reset under the action of its rebound force.
[0023] In this embodiment, the outer surface of each insertion rod 12 is slidably connected to the corresponding connecting frame 7, and the outer surface of each insertion rod 12 is fixedly connected to a first push block 11. The outer surface of each first push block 11 is slidably connected to the corresponding connecting frame 7. Specifically, pushing the first push block 11 will cause the corresponding insertion rod 12 to slide horizontally along the corresponding connecting frame 7. During the installation of the connecting frame 7, until the insertion rod 12 and the corresponding first slot 6 are on the same central axis, the insertion rod 12 can be reset to be inserted into the corresponding first slot 6, thereby quickly fixing the connecting frame 7.
[0024] In a preferred embodiment, a plurality of baffles 8 are fixedly connected to the outer surface of each connecting frame 7, and a plurality of counterweights 13 are provided inside the box body 1. A second slot 9 is provided on the outer surface of each connecting frame 7, and the outer surface of each counterweight 13 is slidably connected to the corresponding connecting frame 7 and baffle 8. A second spring 15 is fixedly connected inside each counterweight 13. By installing the connecting frame 7, the counterweights 13 can be quickly installed by inserting them into the cavity between two adjacent connecting frames 7 and two adjacent baffles 8. By setting multiple counterweights 13, using high-strength materials and reliable connection methods, it is ensured that the counterweights 13 will not loosen or fall off during movement.
[0025] Please see Figure 4 Each second spring 15 has a fixed insertion block 17 at the end away from the corresponding counterweight 13. The outer surface of each insertion block 17 is slidably connected to the corresponding counterweight 13. The outer surface of each counterweight 13 is fixedly connected to a pull block 14. Specifically, during the quick installation of the counterweight 13, the pull block 14 facilitates the quick lifting of the counterweight 13, and the insertion block 17 can slide horizontally into the corresponding counterweight 13.
[0026] In this embodiment, a second push block 16 is fixedly connected to the outer surface of each insert 17, and the outer surface of each second push block 16 is slidably connected to the corresponding counterweight 13. The outer surface of each insert 17 is inserted into the corresponding second slot 9. Specifically, by pushing the second push block 16, the second push block 16 will drive the corresponding insert 17 to slide horizontally along the corresponding counterweight 13. During the installation of the counterweight 13, until the second slot 9 and the corresponding insert 17 are on the same central axis, the corresponding insert 17 is pushed into the corresponding second slot 9 by the rebound force of the second spring 15, thereby quickly installing and fixing the counterweight 13.
[0027] In this embodiment, the interior of the compartment 1 is provided with a plurality of sliding grooves 5, and the inner wall of each sliding groove 5 is provided with a first slot 6. The inner wall of each sliding groove 5 is slidably connected to the corresponding connecting frame 7. The sliding grooves 5 are provided so that the connecting frame 7 can be inserted vertically along the corresponding sliding grooves 5, thereby enabling the connecting frame 7 to be installed quickly.
[0028] like Figure 1 , Figure 2 As shown, the compartment 1 has two cover plates 3 that are snapped together. Each cover plate 3 has a pull plate 4 that is rotatably connected to its inner wall. A step plate 2 is fixedly installed on the inner wall of the compartment 1. The cover plate 3 can be quickly installed by pulling the pull plate 4. Then, the step plate 2 can be installed to support the users and their goods.
[0029] The implementation principle of an elevator car balance adjustment device according to an embodiment of this application is as follows: First, the connecting frame 7 is slid vertically into the corresponding slide groove 5. During this process, by pushing the first push block 11, the first push block 11 will drive the corresponding insertion rod 12 to slide horizontally into the corresponding slot 6. The first spring 10 will be compressed until the insertion rod 12 and the corresponding first slot 6 are on the same central axis. At this time, the first push block 11 is released, and the first spring 10 will push the corresponding insertion rod 12 into the corresponding first slot 6 under its rebound force, so as to quickly fix the connecting frame 7. Then, by lifting the pull block 14, the counterweight block 13 is slid vertically into the cavity between the connecting frame 7 and the corresponding baffle 8. During this process, by pushing the second push block 16, the corresponding insertion block 17 is slid horizontally into the corresponding slot 9. The second spring 15 will be compressed until the insertion block 17 and the corresponding second slot 9 are on the same central axis. Then, the second spring 15 will push the corresponding insertion block 17 into the corresponding second slot 9 under its rebound force, so as to quickly install the counterweight block 13. Finally, the cover plate 3 and the step plate 2 are installed.
[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
