Description

Technical Field

[0001] The utility model relates to the technical field of elevator steel wire ropes, and in particular to an elevator steel wire rope clamping plate. Background Art

[0002] The elevator wire rope clamp is used to fix the wire rope at a specific position in the elevator system. It clamps the wire rope by applying sufficient pressure to prevent it from sliding or loosening, thereby ensuring the safe operation of the elevator.

[0003] The existing rope clamping plate usually buckles two clamping plates together, fixes the two clamping plates with a bolt assembly, forms a rope guide hole after the two clamping plates are fixed, and then clamps the elevator wire rope in the rope guide hole. However, when the wire rope in the rope guide hole needs to be maintained or replaced, both clamping plates need to be completely disassembled and all wire ropes need to be taken out, which is very inconvenient. In addition, the existing rope clamping plate structure is subject to vibration during elevator operation, and is prone to insufficient clamping and poor stability. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 In an embodiment of the utility model, an elevator wire rope clamping plate includes a fixed clamping plate 1 and a connecting plate 3 detachably connected to the fixed clamping plate 1. A plurality of movable clamping plates 2 are movably connected to the inner side of the connecting plate 3. A plurality of propulsion components 4 are provided through the connecting plate 3. One end of each propulsion component 4 can abut against the corresponding movable clamping plate 2. The propulsion component 4 pushes the movable clamping plate 2 to clamp and fix the wire rope. A locking component 5 is fixedly connected to the propulsion component 4. A guide component 6 is provided between the movable clamping plate 2 and the connecting plate 3.

[0025] In this embodiment, the propulsion assembly 4 is a propulsion bolt 41. In order to make the fixation more stable, each propulsion assembly 4 is provided with three propulsion bolts 41, and the three propulsion bolts 41 are evenly distributed on the connecting plate 3 along the longitudinal direction. Among them, the middle propulsion bolt 41 is fixedly connected to the locking assembly 5, and the locking assembly 5 includes a fixing plate 51 and a fastening bolt 52. The fixing plate 51 is fixedly connected to the propulsion bolt 41. The other side of the fixing plate 51 is threadedly connected to the fastening bolt 52, and the bottom end of the fastening bolt 52 can abut against the connecting plate 3. When the propulsion bolt 41 is rotated to move inward, the propulsion bolt 41 pushes the movable splint 2 toward the fixed splint 1, clamping and fixing the wire rope between the movable splint 2 and the fixed splint 1. In order to prevent the propulsion bolt 41 from being loosened due to vibration during elevator operation, the fastening bolt 52 is rotated again so that the bottom end of the fastening bolt 52 abuts against the connecting plate 3.

[0026] One side of the connecting plate 3 is provided with a plurality of longitudinal slots 31 extending horizontally therethrough. The movable splint 2 is mounted within the slots 31 and slidably connected thereto. The width of the movable splint 2 is smaller than that of the slots 31. The guide assembly 6 includes guide slots 61 disposed on either side of the slots 31 and guide blocks 62 disposed on either side of the movable splint 2. The guide blocks 62 are slidably connected to the guide slots 61. The provision of the guide assembly 6 allows for rapid positioning and installation of the movable splint 2, while also ensuring more stable movement of the movable splint 2 within the slots 31, reducing unnecessary friction and preventing shaking or deviation.

[0027] The fixed splint 1 is provided with a plurality of longitudinal first rope grooves 11 in the horizontal direction, and the movable splint 2 is provided with a penetrating second rope groove 21 on the side opposite to the fixed splint 1. The first rope groove 11 and the second rope groove 21 are combined to form an installation groove for the wire rope.

[0028] To more securely clamp and secure the wire rope and prevent it from slipping, a plurality of anti-slip grooves 7 are provided in the first rope groove 11 and the second rope groove 21. The anti-slip grooves 7 are arranged on both sides of the first rope groove 11 and the second rope groove 21, and the anti-slip grooves 7 on both sides are staggered. The anti-slip grooves 7 not only provide more stable clamping of the wire rope, but also disperse the stress on the wire rope to more areas, reducing local stress concentration and extending the service life of the wire rope.

[0029] When the rope clamping plate clamps the wire rope, the sharp edges of the rope grooves can easily break or damage the thin strands of the wire rope under very strong clamping force. Therefore, the notches 8 at the upper and lower ends of the first rope groove 11 and the second rope groove 21 of the present invention are chamfered, and rubber pads 9 are fixedly connected to the notches 8. The chamfered notches 8 can make the edges of the notches 8 smooth and avoid scratching the wire rope. The rubber pads 9 can prevent the wire rope from directly contacting the metal notches, thereby protecting the wire rope.

[0030] The fixing splint 1 and the connecting plate 3 are detachably connected by bolts 10. In order to make the connection more stable, three groups of bolts 10 are provided and are evenly distributed in the horizontal direction.

[0031] When the elevator is running, the lifting bolt 41 is rotated to move inward, and the lifting bolt 41 pushes the movable splint 2 toward the fixed splint 1, clamping the wire rope between the movable splint 2 and the fixed splint 1, so as to fix the wire rope. In order to prevent the lifting bolt 41 from being loosened by vibration during the operation of the elevator, the tightening bolt 52 is rotated again to make the bottom end of the tightening bolt 52 abut against the connecting plate 3. If a wire rope becomes loose or needs to be replaced in the later stage, it is only necessary to rotate the pushing bolt 41 on the corresponding movable splint 2 to release the clamping of the wire rope of the corresponding movable splint 2, so that the wire rope can be easily adjusted or replaced without disassembling the entire rope clamping plate, which is more convenient.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
