Description

Technical Field

[0001] This application relates to the technical field of elevator manufacturing, and more particularly to a guiding roller assembly for an elevator. Background Art

[0002] The guiding roller is used in the elevator guiding device, and more specifically, it is related to a guiding device for controlling the operation of the elevator balance compensation chain and preventing the elevator balance chain from swinging. The elevator balance compensation chain is used to connect the elevator car and the counterweight, mainly for balancing the weight of the hoisting ropes and playing a role in balancing and compensating the operation of the elevator.

[0003] As disclosed in a guiding roller assembly for an elevator in Chinese Patent CN214167042U, the main problem it solves is to realize the detection of the swinging pressure of the compensation chain through the coordinated action of the detection wheel, the tensioning wheel and the lifting column, so as to correspondingly adjust the height of the tensioning wheel and the tension of the compensation chain, thereby reducing the swing of the compensation chain.

[0004] This assembly can reduce the swing of the compensation chain through the detection wheel, the tensioning wheel and the lifting column. However, when adjusting in this assembly, it is still necessary to start the motor to drive the screw to rotate, so as to adjust the height of the tensioning wheel. In this way, it is impossible to quickly adjust according to the swing of the compensation chain in the first place, which is not conducive to the quick and stable action on the compensation chain.

[0026] 1. Through the coordinated setting of the structures in the stabilizing mechanism of the present application, when the compensating chain shakes, the second roller can be squeezed. The squeezed second roller can drive the sliding plate to move outward, thereby driving the push plate to move left and right. When the push plate moves, it can contact and squeeze it, so that the push plate can drive the slider to move up and down on the outer wall of the sliding rod. At the same time, the slider will stretch the first spring, so as to drive the tensioning wheel to move upward, thereby tensioning the compensating chain, thus stabilizing the compensating chain and preventing the compensating chain from shaking significantly. When the compensating chain stops shaking, the first spring rebounds and drives the tensioning wheel to reset, thereby relaxing the compensating chain.

[0027] 2. Through the coordinated setting of the structures in the auxiliary stabilizing mechanism of the present application, the second roller can be stressed alternately on both sides of the compensating chain, which can further stabilize the stabilizing effect of the compensating chain. At the same time, when the compensating chain shakes, the second spring can always keep the second roller attached to the outer wall of the compensating chain due to its own resilience, playing an auxiliary stabilizing role for the compensating chain.

The stabilizing mechanism 31 includes a limiting sleeve 311 fixedly connected to the inner wall of the bottom box 2. A sliding plate 312 is slidably connected to the inner wall of the limiting sleeve 311. A through groove is opened on the outer wall of the bottom box 2, and the inner wall of the through groove opened on the outer wall of the bottom box 2 is in close fit with the outer wall of the sliding plate 312, so as to ensure the limiting fit of the sliding plate 312, thereby maintaining the stability of the sliding plate 312 during movement. The outer wall of the sliding plate 312 is slidably connected to the inner wall of the through groove. One end of the bottom of the sliding plate 312 is fixedly connected with a connecting rod 313, and the end of the connecting rod 313 far away from the sliding plate 312 is fixedly connected with a pushing plate 314. An installation plate 315 is fixedly connected to the inner wall of the bottom box 2. A chute is opened on the outer wall of the installation plate 315, a sliding rod 316 is fixedly connected to the inner wall of the chute, a slider 317 is slidably connected to the outer wall of the sliding rod 316, a first spring 318 is fixedly connected to the bottom end of the slider 317, a first roller 319 is rotatably connected to the inner wall of the bottom box 2, and a tensioning wheel 3110 is rotatably connected to the outer wall of the slider 317.

[0036] Furthermore, the number of the first rollers 319 is four. Two of the first rollers 319 are in a group and are distributed symmetrically left and right on the inner wall of the bottom box 2, so as to cooperate with the tensioning wheel 3110, thereby improving the stability of the compensating chain.

[0037] Moreover, the inner wall of the chute opened on the outer wall of the installation plate 315 is in close fit with the outer wall of the slider 317, so as to fit and limit the outer wall of the slider 317, thereby improving the stability of the up and down movement of the slider 317.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, a preferred embodiment of the guiding roller assembly for an elevator provided by the utility model: the auxiliary stabilizing mechanism 32 includes a sliding frame 321 fixedly connected to the outer wall of the installation plate 315. A second spring 322 is fixedly connected to the inner wall of the sliding frame 321. The number of the second springs 322 is four. Two of the second springs 322 are in a group and are distributed symmetrically left and right on the inner wall of the sliding frame 321, so as to support the left and right sides of a single second roller 323, thereby improving the stability of the second roller 323. One end of the second spring 322 far away from the inner wall of the sliding frame 321 is fixedly connected with a second roller 323, and the outer wall of the second roller 323 is slidably connected to the inner wall of the sliding frame 321.

[0040] Furthermore, the number of the second rollers 323 is four. Two of the second rollers 323 are in a group and are distributed symmetrically left and right inside the bottom box 2. Two of the second rollers 323 are fixedly connected to one end of the sliding plate 312, so as to play an auxiliary stabilizing role on both ends of the compensating chain, thereby improving the stability of the compensating chain.

[0041] Furthermore, the inner wall of the sliding frame 321 is fitted with the outer wall of the second roller 323, so that the outer wall of the second roller 323 can be guided by fitting, thereby maintaining the stability of the second roller 323 during movement.

[0042] The implementation principle of this application is as follows: when the compensation chain shakes, the second roller 323 can be squeezed. The squeezed second roller 323 can drive the sliding plate 312 to move outward, so as to drive the push plate 314 to move left and right. When the push plate 314 moves, it can contact and squeeze the tensioning wheel 3110. In this way, the tensioning wheel 3110 can move upward, and then drive the slider 317 to move up and down on the outer wall of the sliding rod 316. At the same time, the slider 317 will stretch the first spring 318, so as to drive the tensioning wheel 3110 to move upward, thereby tensioning the compensation chain, stabilizing the compensation chain, and preventing the compensation chain from shaking greatly. When the compensation chain stops shaking, the first spring 318 rebounds and drives the tensioning wheel 3110 to reset, thus relaxing the compensation chain.

[0043] By making the second roller 323 bear staggered forces on both sides of the compensation chain, the stability effect of the compensation chain can be further stabilized. At the same time, when the compensation chain shakes, the second spring 322 can always keep the second roller 323 attached to the outer wall of the compensation chain due to its own rebound effect, playing an auxiliary stabilizing role for the compensation chain.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
