[0001] The utility model relates to the technical field of elevators, in particular to an elevator counterweight frame. Background Art
[0002] An elevator is a vertical transportation device, usually used to move people or goods vertically within a building. It consists of one or more elevator cars (or elevator cabins) and a set of guide rails along which the elevator cars move up and down. Elevators can be driven by electric motors, hydraulic systems, or traction mechanisms. In order to reduce the load on the elevator motor, extend the service life of the elevator motor, and reduce energy consumption, an elevator counterweight frame is required.
[0003] During the use of traditional elevator counterweight frames, when the counterweight guide shoes installed at the four corners of the supporting frame are damaged and the guide fails, the guide grooves opened on the left and right columns slide together with the corresponding counterweight guide rails, thereby avoiding the derailment of the elevator counterweight frame and improving the overall safety performance of the elevator counterweight frame.
[0004] However, it does not solve the problem that when the counterweight frame needs to be installed or counterweight blocks need to be added, the counterweight frame needs to be opened and then closed after the installation is completed. However, when installing the counterweight frame, one operator needs to align the cross bar with the bracket, and another operator needs to tighten the fastening bolts for installation. The installation process is relatively inconvenient, which affects the installation efficiency of the elevator counterweight frame. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Reference Figure 1 , Figure 2 and Figure 4 , an embodiment of the utility model is provided: an elevator counterweight frame, including a bracket 1, a positioning groove 4 is opened inside the bracket 1, a cross bar 2 is arranged on the top of the bracket 1, a mounting ring 3 is fixedly connected to the top of the cross bar 2, a slide groove 5 is opened inside the cross bar 2, a limit plate 6 is arranged inside the cross bar 2, the outer wall of the limit plate 6 is slidably connected to the inside of the slide groove 5, the outer wall of the limit plate 6 is fixedly connected to a lever 7, one side of the limit plate 6 is fixedly connected to a connecting pin 8, the outer wall of the connecting pin 8 is slidably connected to the inside of the positioning groove 4, a telescopic rod 9 is arranged inside the cross bar 2, a reset assembly is arranged on the outer wall of the telescopic rod 9, one end of the telescopic rod 9 is fixedly connected to the inside of the cross bar 2, and the other end of the telescopic rod 9 is fixedly connected to the other side of the limit plate 6, the reset assembly includes a first spring 10, the first spring 10 is sleeved inside the outer wall of the telescopic rod 9, one end of the first spring 10 is fixedly connected to the inside of the cross bar 2, and the other end of the first spring 10 is fixedly connected to the other side of the limit plate 6;
[0035] Specifically, when connecting the bracket 1 and the cross bar 2, first, by toggling the lever 7, the connecting pin 8 can be driven to retract into the slide groove 5. The purpose of this step is to facilitate the buckling of the cross bar 2 and the bracket 1. After the cross bar 2 is buckled with the bracket 1, the lever 7 is released, and the tension of the first spring 10 will push the limit plate 6, thereby driving the connecting pin 8 to reset and extend out of the cross bar 2. In this step, the connecting pin 8 will be inserted into the positioning groove 4 to pre-buckle the cross bar 2 and the bracket 1. This pre-buckle provides a solid foundation for subsequent fixation. Finally, the cross bar 2 and the bracket 1 are further fixed with fastening bolts. The use of fastening bolts can ensure the tightness and stability of the connection, thereby improving the safety and durability of the entire structure.
[0036] Reference Figure 1 , Figure 3 and Figure 5A card slot 11 is provided inside the bracket 1, and the card slots 11 are arranged in a linear array inside the bracket 1. A counterweight block 12 is provided on the outer wall of the bracket 1. A limiting slot 13 is provided inside the counterweight block 12. The counterweight block 12 is slidably connected to the inside of the bracket 1 through the limiting slot 13. A limiting block 17 is fixedly connected inside the counterweight block 12. A limiting plate 2 14 is slidably connected inside the counterweight block 12. A limiting slot 2 16 is provided inside the limiting plate 14. The limiting plate 2 14 is slidably connected to the outer wall of the limiting block 17 through the limiting slot 2 16. The limiting plate 2 14 is slidably connected to the outer wall of the limiting block 17 through the limiting slot 2 16. A card block 15 is fixedly connected to one side of the bracket 1, and the outer wall of the card block 15 is embedded in the card slot 11. A telescopic rod 2 18 is arranged inside the counterweight 12, and a second spring 19 is sleeved on the outer wall of the telescopic rod 2 18. One end of the telescopic rod 2 18 and the second spring 19 are fixedly connected to the other side of the limiting plate 2 14, and the other ends of the telescopic rod 2 18 and the second spring 19 are fixedly connected to the counterweight 12. A track 20 is arranged on one side of the bracket 1, and a limiting groove 3 21 is arranged inside the bracket 1. The bracket 1 is slidably connected to the outer wall of the track 20 through the limiting groove 3 21;
[0037] Specifically, in the process of installing the counterweight 12, we must first ensure that the number of counterweights 12 meets the requirements. Through the limiting groove 13, we can easily slide the counterweight 12 into the bracket 1. The block 15 in the counterweight 12 can be easily embedded in the slot 11 on the bracket 1. When the block 15 is embedded in the slot 11, the counterweight 12 is firmly fixed on the bracket 1, ensuring its stability and reliability. However, in order to ensure that the block 15 does not accidentally slide out after being embedded in the slot 11, the limiting plate 2 14 limits the block 15 by sliding inside the counterweight 12 to prevent it from moving when subjected to force or vibration. The limiting block 17 slides on the outer wall through the limiting groove 2 16, providing further limiting protection for the block 15. This double limiting design enables the counterweight 12 to remain in a stable fixed state when subjected to external force. Finally, in order to ensure that the block 15 is more stable when embedded in the slot 11, the tension support of the second spring 19 is also added. This design can not only ensure that the card block 15 is not easy to slide out after being inserted into the card slot 11, but also provide a certain buffering and shock absorbing effect when subjected to external force, further improving the stability and reliability of the counterweight 12.
[0038] Working principle: When the elevator counterweight frame is used, firstly, when installing the counterweight block 12, it is only necessary to slide the corresponding number of counterweight blocks 12 directly into the bracket 1 through the limiting groove 13, and then make the block 15 in the counterweight block 12 embed into the inside of the card slot 11 on the bracket 1, so as to fix the counterweight block 12 in position, and the block 15 is limited by sliding inside the counterweight block 12 through the limiting plate 2 14, and the limiting plate 2 14 slides on the outer wall of the limiting block 17 through the limiting groove 2 16 to further limit the block 15, and then the second spring 19 is tensioned. The force support makes it difficult for the card block 15 to slide out when it is embedded in the card slot 11. When the bracket 1 is connected to the cross bar 2, it is only necessary to retract the cross bar 2 into the slide slot 5 by pushing the lever 7, and then buckle the cross bar 2 with the bracket 1. Then, release the lever 7, which will push the limit plate 6 under the tension of the first spring 10 to drive the connecting pin 8 to return to the cross bar 2 and extend it out. Then, the connecting pin 8 is inserted into the positioning groove 4 to pre-buckle the cross bar 2 and the bracket 1, and then use the fastening bolts to further fix the cross bar 2 and the bracket 1.
