Description

Technical Field

[0001] This utility model relates to the technical field of elevator installation, specifically to a hoisting device for elevator installation. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical.

[0003] During elevator installation, appropriate devices are needed to assist in elevator hoisting. One such hoisting device, with patent publication number CN222540302U, incorporates a guide assembly. This design allows the second steel wire rope to move downwards via a stepper motor. By fixing the connecting seat to the ground, the hoisting structure can guide the movement of elevator components by sliding up and down on the outside of the second steel wire rope through guide sleeves on both sides of the hoisting structure. This prevents the hoisting structure from swaying during its ascent.

[0004] However, due to the different usage environment, the second wire rope cannot be fully adapted to the actual height for guidance, and its practicality is insufficient. Utility Model Content

The fixed base 1 has a through slot 2 on its inner side in the middle. The outer side of the top of the fixed base 1 is connected to the bottom side of the connecting frame 3. The winch 4 is located on the upper part of the connecting frame 3. The outer side of the winch 4 is connected to and wound with the connecting rope 5. The bottom side of the connecting rope 5 is connected to the middle of the top side of the upper frame 6. The bottom side of the upper frame 6 is connected to the outer middle of the top side of the hoisting box 7. The middle parts of the left and right sides of the hoisting box 7 are respectively connected to the inner ends of a set of guide sleeves 11. The lower middle parts of the left and right sides of the connecting frame 3 are respectively connected to the inner sides of a set of stepper motors 8. The output end of the stepper motor 8 is connected to the middle of the inner end of the take-up reel 9. The outer side of the take-up reel 9 is connected to and... A guide rope 10 is wound around the bottom of the guide rope 10 and connected to the middle of the top side of the fixed plate 12. Each set of guide sleeves 11 is movably sleeved on the outside of the guide rope 10 on the same side. A locking pin mechanism is provided between the connecting frame 3 and the winding wheel 9. The fixed seat 1 is placed at a high position of the elevator installation location and fixed. Then, the two sets of stepper motors 8 are run to make the winding wheel 9 rotate and unwind the guide rope 10, so that the fixed plate 12 moves downward to a low position and is fixed at a low position by a ground bolt. Then, the winding wheel 9 is fixed to prevent rotation by the locking pin mechanism, so that the guide rope 10 is taut. The elevator installation components can be placed in the hoisting box 7. When the winch 4 is running, the connecting rope 5 can be wound and unwound. The hoisting box 7 is connected to the upper frame 6 and raised and lowered accordingly. With the constraint and guidance of the guide sleeves 11 by the two sets of guide ropes 10, the vertical movement of the hoisting box 7 can be controlled to avoid deviation.

[0024] The locking mechanism includes a perforated plate 13, an inner sliding sleeve 14, a sliding pin 15, a ferromagnetic sheet 16, an outer frame 17, an electromagnet 18, and a connecting spring 22. The upper inner side of each set of stepper motors 8 in the connecting frame 3 is connected to the outer side of a set of inner sliding sleeves 14. The inner wall of the inner sliding sleeve 14 is laterally slidably connected to the outer wall of the sliding pin 15. The outer end of the sliding pin 15 is connected to the middle of the inner side of the ferromagnetic sheet 16. The outer side of the inner side of the ferromagnetic sheet 16 is connected to the outer side of the inner sliding sleeve 14 on the outer side of the connecting frame 3 by a connecting spring 22. The outer side of each set of connecting springs 22 at the outer end of the connecting frame 3... Each is connected to the inner end of a set of outer frames 17. Electromagnets 18 are connected to the inner and outer sides of the outer frames 17. The outer ring side of the take-up wheel 9 is connected to the inner ring side of the perforated plate 13. When the electromagnet 18 is energized, it can attract the ferromagnetic sheet 16, driving the sliding pin 15 outward to avoid interfering with the rotation of the take-up wheel 9. When the electromagnet 18 is de-energized, under the elastic action of the connecting spring 22, the ferromagnetic sheet 16 drives the sliding pin 15 to slide to the left inside the inner sliding sleeve 14 and into the corresponding hole in the perforated plate 13 to fix the take-up wheel 9 to prevent rotation and improve stability.

[0025] It also includes a chamfered groove 19, and each set of sliding pins 15 has a chamfered groove 19 on the outer ring side of the inner end; the chamfered groove 19 can reduce the inner end of the sliding pin 15, making it easier for the sliding pin 15 to be inserted into the hole plate 13.

[0027] It also includes a lighting lamp 21, with the bottom left and right sides of the mounting base 1 respectively connected to the top side of a set of lighting lamps 21; when the lighting lamps 21 are powered on, they can provide illumination, optimize the lighting environment, and improve convenience.

[0028] In summary, when using a hoisting device for elevator installation, the fixed base 1 is placed at a high position on the elevator installation site and fixed. When the electromagnet 18 is energized, it can attract the ferromagnetic plate 16, driving the sliding pin 15 outward to avoid interference with the rotation of the winding wheel 9. Then, the two sets of stepper motors 8 run, causing the winding wheel 9 to rotate and unwind the guide rope 10, allowing the fixed plate 12 to move downward to a low position. The fixed plate 12 is then fixed in the low position by the ground bolt. When the electromagnet 18 is de-energized, under the elastic action of the connecting spring 22, the ferromagnetic plate 16 drives the sliding pin 15 to slide to the left inside the inner sliding sleeve 14, and then... The corner groove 19 can reduce the inner end of the sliding pin 15, making it easier for the sliding pin 15 to be inserted into the perforated plate 13, fixing the winding wheel 9 to prevent rotation, and keeping the guide rope 10 taut. The elevator installation components can be stored inside the hoisting box 7. When the winch 4 is running, it can wind and unwind the connecting rope 5. The hoisting box 7 is raised and lowered accordingly via the upper frame 6. The vertical movement of the hoisting box 7 can be controlled by the constraint and guidance of the guide sleeve 11 by the two sets of guide ropes 10 to avoid deviation. In addition, the information board 20 can display the information of this hoisting box 7 for easy use. When the lighting lamp 21 is powered on, it can provide illumination and optimize the lighting environment.
