Description

Technical Field

[0001] The utility model relates to the field of elevator counterweight frames, in particular to a stable counterweight frame for elevator installation. Background Art

[0002] The elevator counterweight frame is an important component of the elevator and is usually made of steel. Its main function is to support the elevator counterweight so that the elevator can rise and fall smoothly. The elevator counterweight frame usually consists of two main parts: the counterweight frame frame and the counterweight block. The counterweight frame is a frame structure made of steel used to support the counterweight block. The counterweight block is a heavy steel block that is usually suspended under the counterweight frame. When the elevator rises, the counterweight block will move downward to help balance the weight of the elevator and make it more stable. When the elevator descends, the counterweight block will move upward, also playing the role of balancing the weight of the elevator.

[0003] The existing stable counterweight frame for elevator installation has multiple counterweights installed on the frame. Since the counterweights are heavy, they need to be stacked together during installation. The counterweights are prone to collision and breakage, which shortens their service life.

[0004] Therefore, it is necessary to propose a stable counterweight frame for elevator installation to solve the above problems. Utility Model Content

[0031] The dividing mechanism can separate the multiple counterweight blocks to avoid the situation where the multiple counterweight blocks collide with each other and cause breakage.

[0032] The edges of the end faces of the partition plate 15 away from the mounting plate 16 are chamfered;

[0033] The chamfered partition 15 has an inclined surface edge, and can be inserted into the gap between two counterweights, thereby separating the counterweights.

[0034] A top block 28 is fixedly connected to the top of the counterweight frame 2, and a connecting column 29 is fixedly connected to the bottom of the top block 28. A third spring 30 is sleeved on the outer side of the connecting column 29. One end of the third spring 30 is fixedly connected to the top block 28, and the other end of the third spring 30 is fixedly connected to a connecting block 31. The connecting block 31 is slidably connected to the connecting column 29, and two partitions 15 are slidably connected to the connecting block 31; the initial state of the third spring 30 is a stretched state; the reaction force generated by the stretching of the third spring 30 acts on the surface of the connecting block 31, and the connecting block 31 is fixedly connected to two of the partitions 15, which can assist the upper mounting plate 16 and the partition 15 to drive the counterweight block to move upward, thereby assisting the installation of the counterweight block.

[0035] It should be noted that the utility model is a stable counterweight frame for elevator installation, and the reaction force generated by the initial stretching of the third spring 30 acts on the surface of the connecting block 31, thereby ensuring the stability of the mounting plate 16 at the top;

[0036] When in use, place the counterweight block on the upper surface of the base plate 1, and adjust the two connecting blocks 31 to move downward until the bottom of the vertical slot 5. The third spring 30 is further stretched to push the mounting plate 16, so that the two mounting plates 16 move toward each other. The end of the partition 15 away from the mounting plate 16 is inserted into the gap between the multiple counterweight blocks, so that the multiple counterweight blocks can be separated. While pushing the mounting plate 16, pull the T-shaped column 24 upward to separate the protrusion 26 from the circular groove 27, the protrusion 22 can be at the top of the inclined groove 21, and the limit block 18 is in the mounting groove 17. After the partition 15 separates the counterweight blocks, use the third spring The spring 30 acts as an auxiliary force to lift the mounting plate 16 and the counterweight, and then the hand is released. Under the elastic force of the second spring 25, the protrusion 26 on the surface of the T-shaped column 24 is inserted into the circular groove 27 again. The T-shaped column 24 is fixedly connected to the adjustment plate 23, and the adjustment plate 23 moves downward with the T-shaped column 24. The protrusion 22 is fixedly connected to the adjustment plate 23, and the protrusion 22 moves with the adjustment plate 23. Relative sliding occurs between the protrusion 22 and the inclined groove 21, driving the limit block 18 to approach the limit groove 20 until it is inserted into the limit groove 20, thereby giving the mounting plate 16 a limit after adjustment, and also ensuring the stable state of multiple counterweights after being separated;

[0037] Next, place multiple counterweights on the surface of the base plate 1, push the mounting plate 16 below, pull the T-shaped column 24, separate the counterweights, until the limit block 18 is aligned with the limit groove 20, release your hand, adjust the mounting plate 16 to limit it, and ensure that the counterweights are installed stably. After the limit block 18 cooperates with the limit groove 20, the mounting plate 16 can be limited after adjustment. The upper limit block 18 can move relative to the limit groove 20 in the up and down directions. The reaction force generated by the deformation of the first spring 12 is used to provide buffering for multiple counterweights, ensuring that the counterweights are installed stably and preventing the counterweights from colliding with each other and breaking, thereby extending their service life. Then rotate the limit column 13 and fix the end of the limit column 13 away from the base plate 1 to the top plate 4.
