Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction shaft construction technology, and in particular to a weight compensation device for traction steel wire rope used in traction shaft construction hoists. Background Technology
[0002] A traction construction hoist is a device that uses a traction machine to drive a cage and counterweight up and down along a guide rail frame. The traction wire rope plays a crucial role in connecting and transmitting power. However, in actual operation, due to the weight difference between the cage and the counterweight, as well as the dynamic changes during hoist operation, the stress condition of the traction wire rope is complex, which may lead to problems such as accelerated wire rope wear and operational instability. Furthermore, when there is a significant weight imbalance between the cage and the counterweight, it may also affect the hoist's operating efficiency and safety.
[0003] The weight compensation device uses its own weight to offset the weight difference between the car and the counterweight, thereby maintaining the balance of traction force. When the elevator goes up or down, the steel wire rope generates varying torque due to its own weight. If this torque is not balanced, it will affect the stability of the elevator and the efficiency of the motor.
[0004] Conventional weight compensation devices are usually fixed to both sides of the cage and the counterweight by chains to achieve the compensation function. However, in some super high-rise buildings or open shafts, the wind speed is often high. When the elevator is running, the compensation device (chain) will shake, which can easily scrape the guide rail brackets, electrical switch brackets and other components in the shaft, thus causing elevator failure and safety accidents.
[0005] To address this issue, a traction steel wire rope weight compensation device for a traction-type shaft construction hoist is designed to provide an alternative technical solution. Utility Model Content

[0015] As a preferred embodiment of the traction steel wire rope weight compensation device for a traction shaft construction hoist provided by this utility model, counterweight plates are fixed at both ends of the outer side of the tensioning guide rail.

[0038] Example 1
[0039] Reference Figures 1-3 A traction steel wire rope weight compensation device for a traction hoist in a shaft construction machine includes a drive mechanism, a compensation rope 6 and a tensioning mechanism 8.
[0040] The drive mechanism is installed inside the wall 1 and is used to adjust the height of the cage 5. At this time, the cage 5 is also located inside the wall 1.
[0041] The drive mechanism includes a drive wheel 2, an auxiliary wheel 3, a traction rope 4, and a counterweight 7. The drive wheel 2 is rotatably connected to the top of the wall 1. The traction rope 4 is wound around the outside of the drive wheel 2, so that the position of the traction rope 4 can be adjusted by rotating the drive wheel 2. The bottom of one end of the traction rope 4 is fixed to the cage 5, so that the movement of the traction rope 4 outside the drive wheel 2 drives the cage 5 to rise and fall inside the wall 1. The bottom of the other end of the traction rope 4 is fixed to the counterweight 7, and the bottom of the counterweight 7 is fixed to the compensating rope 6, so that the tensioning mechanism 8 can compensate for the weight of the cage 5 through the compensating rope 6. The auxiliary wheel 3 is rotatably connected to the bottom of the drive wheel 2 inside the wall 1, so that the auxiliary wheel 3 assists the drive wheel 2 in adjusting the traction rope 4 and increases support.
[0042] The compensating rope 6 is installed between the cage 5 and the tensioning mechanism 8 to connect the cage 5 and the tensioning mechanism 8.
[0043] The tensioning mechanism 8 is installed at the bottom inside the wall 1, and the tensioning mechanism 8 achieves weight compensation through the compensating rope 6;
[0044] The tensioning mechanism 8 includes a tensioning guide rail 9, a tensioning wheel 11, and a guide shoe 13. The outer side of the tensioning wheel 11 is wound with the compensating rope 6, allowing the compensating rope 6 to move outside the tensioning wheel 11. Guide shoes 13 are fixed on both sides of the top of the tensioning wheel 11. The tensioning guide rail 9 is slidably connected to the inner side of the guide shoe 13, so that the height of the tensioning wheel 11 can be adjusted by the sliding of the guide shoe 13 on the outer side of the tensioning guide rail 9, and the tensioning wheel 11 can only move straight up and down inside the wall 1 through the cooperation of the guide shoe 13 and the tensioning guide rail 9. A fixing frame 10 is fixed on the side of the tensioning guide rail 9 away from the tensioning wheel 11. The fixing frame 10 is fixed to the wall 1, so that the position of the tensioning guide rail 9 is fixed and supported by the fixing frame 10. Counterweight plates 12 are fixed at both ends of the outer side of the tensioning guide rail 9, so that the counterweight can be increased by the counterweight plates 12.
[0045] Preferably, both ends of the guide shoe 13 are internally threaded with fixing bolts, thereby increasing the positioning friction between the guide shoe 13 and the tensioning guide rail 9 by rotating the fixing bolts.
[0046] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.
[0047] The usage process of the traction steel wire rope weight compensation device for a traction shaft construction hoist provided by this utility model is as follows: In use, the drive wheel 2 can be driven to rotate through an external structure. The rotation of the drive wheel 2 drives the traction rope 4 to move through the auxiliary wheel 3. The movement of the traction rope 4 drives the cage 5 to rise and fall. When the cage 5 rises and falls, the counterweight 7 and the compensation rope 6 fixed at the bottom of the cage 5 rotate outside the tension wheel 11, thereby realizing the weight compensation when adjusting the cage 5. During weight compensation, the tensioning mechanism 8 can only move straight up and down inside the wall 1 through the cooperation of the tensioning guide rail 9 and the guide shoe 13, preventing damage caused by scratching the guide rail and other structures.
[0048] Example 2
[0049] Reference Figures 4-8 Based on the above embodiment one, an optional solution is disclosed:
[0050] An extension column is fixed at the center of both sides of the tension wheel 11. A positioning mechanism for squeezing the extension column is installed inside the wall 1. The height position of the extension column can be limited by the positioning mechanism, thereby limiting the bottom position of the compensation rope 6 outside the tension wheel 11, and achieving better weight compensation of the cage 5 by the traction rope 4.
[0051] The positioning mechanism includes a support shell 14, a pressing plate 15, a gear 18, and a brake block 22. The support shell 14 is bolted to the wall 1. The pressing plate 15 is slidably connected inside the support shell 14, so that the pressing plate 15 slides out inside the support shell 14 and presses and limits the height position of the extension column. The two sides of one end of the pressing plate 15 are rotatably connected to the gear 18. The bottom of the gear 18 is meshed with a rack 20, and the rack 20 is fixed inside the support shell 14, so that the rotation of the gear 18 drives the pressing plate 15 to translate inside the support shell 14. The brake block 22 is provided inside the pressing plate 15 and located at one end of the gear 18. The brake block 22 is slidably connected to the support shell 14, so that when the brake block 22 extends out of the pressing plate 15 and enters the interior of the support shell 14, the pressing plate 15 cannot translate inside the support shell 14.
[0052] Preferably, a displacement drive motor 19 is fixed inside the extrusion plate 15. The output end of the displacement drive motor 19 is connected to the gear 18, so that when the displacement drive motor 19 is working, it drives the two gears 18 to rotate in the same direction through the two transmission shafts.
[0053] Preferably, the bottom of one end of the extrusion plate 15 is provided with extrusion surfaces 16 of different heights, and two adjacent extrusion surfaces 16 are connected by extrusion ramps 17. This allows the extrusion plate 15 to extend out of the support shell 14, extruding the extension column through different extrusion surfaces 16, and allowing the extension column to enter the bottom of the next extrusion surface 16 for positioning through the extrusion ramps 17.
[0054] Inside the extrusion plate 15 and at one end of the displacement drive motor 19, a push rod motor 23 is fixed. The push rod of the push rod motor 23 is fixed with a lifting block 21. The outer side of the lifting block 21 is slidably connected to the extrusion plate 15, so that the lifting block 21 can extend and retract inside the extrusion plate 15. Inside the bottom end of the lifting block 21, a brake block 22 is slidably connected, so that the brake block 22 can retract into the interior of the lifting block 21. At the top of the lifting block 21 and inside the brake block 22, a return spring 24 is fixed. When the brake block 22 does not correspond to the groove opened inside the support shell 14, the brake block 22 is completely inside the lifting block 21 due to the compression of the return spring 24. When the brake block 22 corresponds to the groove, the brake block 22 is lowered by the rebound after being compressed by the return spring 24, so that the brake block 22 enters the corresponding groove.
[0055] The usage process of the traction steel wire rope weight compensation device for the traction hoist provided by this utility model is as follows: During use, the operation of the displacement drive motor 19 drives the gear 18 to rotate, so that the gear 18 drives the extrusion plate 15 to extend inside the support shell 14, so that the extrusion plate 15 extrudes the extension column through the extrusion surface 16. At the same time, during extrusion, the push rod motor 23 drives the lifting block 21 to descend, so that the brake block 22 enters the groove inside the support shell 14, limiting the position of the extrusion plate 15 inside the support shell 14.
[0056] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
