Description
Technical Field
[0001] This utility model relates to the field of counterweight technology, and in particular to an elevator counterweight. Background Technology
[0002] The main function of the elevator counterweight is to balance the weight of the elevator car, thereby reducing the power of the traction motor and the torque on the traction sheave and worm gear. During elevator operation, the counterweight moves as the elevator goes up or down, always maintaining a balanced state with the elevator car to ensure smooth elevator operation.
[0003] When installing counterweights, multiple counterweights need to be stacked on top of each other. However, there is no direct connection between the stacked counterweights, which makes the connection between the counterweights unstable. This may lead to relative displacement of the counterweights inside the elevator car, which is not conducive to the stability of the elevator operation. Utility Model Content

[0011] Preferably, a circular block is fixedly connected to one end of the threaded pin, and the outer diameter of the circular block is larger than the outer diameter of the threaded pin.
[0012] The effect achieved by the above-mentioned components is that by setting up a round block, one end of the threaded pin can be blocked, which helps to prevent the nut from falling off the threaded pin due to misoperation and thus easily being lost.

[0017] Preferably, a washer is provided between the screw hole block and the round hole block, and the outer surface of the threaded rod is inserted into the inner wall of the washer.
[0018] The effect achieved by the above components is that by setting a shim, one side of the screw hole block can be replaced by the other side of the round hole block, thereby increasing the contact area between the screw hole block and the round hole block, which helps to prevent the screw hole block from loosening.
[0019] Preferably, U-shaped blocks are symmetrically fixedly connected to both sides of the counterweight body, and the outer surface of the circular hole block is inserted into the inner wall of the U-shaped block.

Detailed Implementation
[0029] Example 1, referring to Figures 1-3As shown, this embodiment discloses an elevator counterweight, including a counterweight body 1. A connecting device 2 is provided on the outer surface of the counterweight body 1. The connecting device 2 includes two connecting plates 21. One side of the two connecting plates 21 is symmetrically fixedly connected to one side of the counterweight body 1. A connecting groove 22 is symmetrically opened on the other side of the counterweight body 1. The size and shape of the outer surface of the connecting plate 21 are adapted to the size and shape of the inner wall of the connecting groove 22. A plurality of threaded pins 23 are uniformly fixedly connected to one side of the connecting groove 22. A plurality of auxiliary grooves 24 are uniformly opened on one side of the connecting plate 21. Mounting blocks 3 are provided at both ends of the counterweight body 1. A disassembly device 4 is provided between the mounting block 3 and the counterweight body 1. By setting the connecting plate 21 and the connecting groove 22, the connecting plate 21 is inserted into the inner wall of the connecting groove 22 of the adjacent counterweight, and the threaded pins 23 are inserted into the inner wall of the auxiliary groove 24. This allows for connection and positioning between two adjacent counterweights, which helps prevent relative displacement of the counterweights inside the elevator car and facilitates the stability of elevator operation.
[0030] Reference Figure 2 and Figure 3 As shown, a nut 25 is threaded onto the outer surface of the threaded pin 23. By setting the nut 25 and rotating it, one side of the nut 25 abuts against one side of the connecting plate 21 on the side of the adjacent counterweight. This provides auxiliary fixation for the connecting plates 21 and connecting grooves 22 of the two adjacent counterweights, which helps prevent the connecting plates 21 from detaching from the inner wall of the connecting grooves 22 of the adjacent counterweights. A rubber pad 26 is fixedly connected to one side of the nut 25. The outer surface of the threaded pin 23 is inserted into the inner wall of the rubber pad 26. By setting the rubber pad 26, the friction on one side of the nut 25 can be increased, making it less likely for the nut 25 to loosen when the rubber pad 26 on one side of the nut 25 abuts against the connecting plate 21.
[0031] Reference Figure 2 and Figure 3 As shown, a round block 27 is fixedly connected to one end of the threaded pin 23. The outer diameter of the round block 27 is larger than the outer diameter of the threaded pin 23. By setting the round block 27, one end of the threaded pin 23 can be blocked, which helps to prevent the nut 25 from being dislodged from the threaded pin 23 due to misoperation and thus easily lost. A locking block 28 is symmetrically fixedly connected to one side of the counterweight body 1. The two sides of the locking block 28 are respectively fixedly connected to one side of the two connecting plates 21. A locking groove 29 is symmetrically opened on the other side of the counterweight body 1. The size and shape of the outer surface of the locking block 28 are adapted to the size and shape of the inner wall of the locking groove 29. By setting the locking block 28 and the locking groove 29, the locking block 28 can be inserted into the inner wall of the adjacent locking groove 29, which can provide auxiliary limiting between the two adjacent counterweights and further prevent relative displacement between the counterweights.
[0032] Reference Figure 4 and Figure 5As shown, the easy-to-disassemble device 4 includes two round hole blocks 41. One side of each round hole block 41 is symmetrically fixedly connected to both sides of the mounting block 3. A threaded rod 42 is inserted into the inner wall of the round hole block 41. One end of the threaded rod 42 is fixedly connected to one side of the counterweight body 1. A threaded hole block 43 is threadedly connected to the outer surface of the threaded rod 42. By setting two threaded rods 42, the two threaded rods 42 are inserted into the inner wall of the two round hole blocks 41 respectively, so that one side of the round hole block 41 abuts against one side of the counterweight body 1. Then, the threaded hole block 43 is sleeved on one end of the threaded rod 42. By rotating the threaded hole block 43, one side of the threaded hole block 43 abuts against one side of the round hole block 41. This can fix the mounting block 3 and the counterweight body 1, and also facilitate the individual disassembly, maintenance and replacement of the mounting block 3.
[0033] Reference Figure 4 and Figure 5 As shown, a washer 44 is provided between the screw hole block 43 and the round hole block 41. The outer surface of the threaded rod 42 is inserted into the inner wall of the washer 44. By providing the washer 44, one side of the screw hole block 43 can be replaced to abut against one side of the round hole block 41, thereby increasing the contact area between the screw hole block 43 and the round hole block 41, which helps to prevent the screw hole block 43 from loosening. U-shaped blocks 45 are symmetrically fixed to both sides of the weight block body 1. The outer surface of the round hole block 41 is inserted into the inner wall of the U-shaped block 45. By providing the U-shaped block 45, the U-shaped block 45 can provide auxiliary limiting for the round hole block 41, thereby making the fixing of the mounting block 3 more stable.
[0034] Working principle: The connecting plate 21 is inserted into the inner wall of the connecting groove 22 of the adjacent counterweight, the locking block 28 is inserted into the inner wall of the locking groove 29, and the threaded pin 23 is inserted into the inner wall of the auxiliary groove 24. Then, the nut 25 is rotated so that the rubber pad 26 on one side of the nut 25 abuts against one side of the connecting plate 21 on the side of the connected counterweight. This provides auxiliary fixation to the connecting plates 21 and connecting grooves 22 of the two adjacent counterweights, thereby connecting and limiting the movement of the two adjacent counterweights. This helps prevent relative displacement of the counterweights inside the elevator car, facilitating electrical... The stability of the ladder operation; when it is necessary to install the mounting block 3, insert the two threaded rods 42 into the inner walls of the two round hole blocks 41 respectively, insert the round hole blocks 41 into the inner wall of the U-shaped block 45, and make one side of the round hole block 41 abut against one side of the counterweight body 1. Then, put the screw hole block 43 and the washer 44 on one end of the threaded rod 42, rotate the screw hole block 43, and make one side of the washer 44 abut against one side of the round hole block 41. This can fix the mounting block 3 and the counterweight body 1, and also facilitate the individual disassembly, maintenance and replacement of the mounting block 3.
