Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to an elevator rope end installation structure. Background Art

[0002] The elevator rope end mounting plate is an important component for installing the elevator rope end above the hoistway; during the installation and maintenance of the elevator, the correct installation of the rope end mounting plate is crucial, which directly affects the operating stability and safety of the elevator.

[0003] Chinese patent CN202023147501.2 discloses an elevator and rope end plate installation structure, in which a fixing assembly and a transfer assembly are respectively installed on both sides of a plate body of the installation plate, so that the plate body can rotate around the horizontal axis of the fixing assembly. When the car moves up and down in the hoistway, an angle is generated between the traction rope and the vertical direction. Under the action of the traction force of the traction rope, the plate body is pulled to rotate around the horizontal axis of the fixing assembly, so that the force of the rope end assembly is always consistent with the length extension direction of the traction rope, which can reduce or avoid the friction between the rope end assembly and the traction rope, thereby reducing the wear between the rope end assembly and the traction rope.

[0004] However, the car is heavy, and when the speed of the car changes during operation, the inertia of the car is large. The plate body will continue to rotate slightly under the action of the inertia of the car, and then will rotate slightly again under the tension of the traction rope, causing the car to shake and affecting the passengers' experience.

[0047] Two blocking components 5, corresponding to the rotating shafts 3 one by one, are used to block the rotation of the rotating shafts 3 under the action of inertia;

[0048] Through the above technical solutions, in this embodiment, the plate body 1 is placed above the hoistway, and the two rotating shafts 3 on both sides of the plate body 1 are respectively fixed above the hoistway by using the two fixing components 4; one ends of several wire ropes are respectively fixed on a rope socket fixer 2, and the other ends of the wire ropes are respectively passed through the pulleys on the car and then fixed to the correct positions; when the elevator starts to run, the rope socket fixer 2 is subjected to the tension of the steel wire rope; since the rope socket fixer 2 is vertically fixed on the plate body 1, the plate body 1 will rotate under the tension of the rope; the plate body 1 rotates within the fixing component 4; when the speed of the car slows down or even stops, the tension received by the plate body 1 suddenly decreases, and the blocking component 5 is used to prevent the rotating shaft 3 from rotating under the action of inertia, so that the plate body 1 is always perpendicular to the direction of the rope; preventing the car from shaking;

[0049] As an implementation manner of the present invention, please refer to Figure 3 and Figure 4 As shown, the fixing component 4 includes:

[0050] A fixing seat 41 is arranged below the corresponding rotating shaft 3;

[0051] A fixing ring 42 is sleeved outside the corresponding rotating shaft 3;

[0052] A connecting rod 43 is fixedly arranged between the fixing seat 41 and the fixing ring 42;

[0053] Through the above technical solution, in this embodiment, the fixed seat 41 is fixedly arranged above the hoistway; the fixing ring 42 is fixed through the connecting rod 43, and the rotating shafts 3 on both sides of the plate body 1 are respectively rotatably arranged above the hoistway by the fixing ring 42; the plate body 1 can adjust the inclination angle of the plate body 1 according to the pulling direction of the rope, so that the pulling direction of the rope is kept in the same straight line as the rope head fixer 2, reducing the wear of the rope.

[0054] As an implementation manner of the present invention, please refer to Figures 2 - 4 As shown in the figure, the blocking component 5 includes:

[0055] A rotating wheel 51, fixedly arranged on the side of the corresponding rotating shaft 3 away from the plate body 1;

[0056] A plurality of first limiting grooves 52, arranged in a circumferential array on the side wall of the rotating wheel 51;

[0057] A limiting base 53, fixedly arranged on the side of the connecting rod 43 away from the plate body 1 and located directly below the rotating wheel 51;

[0058] A first sliding groove 54, opened at the upper end of the limiting base 53;

[0059] A first limiting block 55, slidably arranged in the first sliding groove 54;

[0060] A first spring 56, arranged in the first sliding groove 54;

[0061] Through the above technical solution, in this embodiment, when the rotating shaft 3 stops rotating, the rotating wheel 51 stops rotating.

Therefore, when the rotating wheel 51 rotates under a large pulling force, the bottom of the rotating wheel 51 contacts the upper end of the first limiting block 55 when rotating, gradually pressing the first limiting block 55 downward, and the first spring 56 is compressed and shortened. When the first limiting block 55 moves below the rotating wheel 51, the rotating wheel 51 rotates a certain angle. When the next first limiting groove 52 moves directly above the first limiting block 55, the first limiting block 55 moves upward under the action of the first spring 56 and re-enters the new first limiting groove 52; the first limiting block 55 limits the rotation of the rotating wheel 51 due to inertia when the pulling force is small or there is no pulling force, reducing the rotation angle of the rotating shaft 3 and preventing the car from shaking.
