Abstract
The utility model relates to an idler wheel guide shoe of elevators. The idler wheel guide shoe is mainly used in intermediate-speed and high-speed elevators, wherein the speed of the intermediate-speed and high-speed elevators is larger or equal to 1m/s and smaller or equal to 5m/s. Three idler wheels of the idler wheel guide shoe are fixed on controlling rods through idler wheel shafts respectively, and the controlling rods are L-shaped. Long ends of the controlling rods are contacted with springs, and after the idler wheels are stressed, the long ends of the controlling rods oppress the spring to buffer. Limit bolts capable of adjusting through threads are arranged at short ends of the controlling rods, and when the idler wheels sway, the maximum swaying and excursion of the idler wheels are limited. Compression degree of the springs is adjusted in advance by adjusting limit nuts so as to adjust the distances of openings of every two idler wheels, and initial pressure when the idler wheels are contacted with guide rails can be controlled to be in balance. When a car undergoes imbalanced stress to sway, any idler wheel which is stressed and deformed can sway around an A point, a B point and a C point slightly and respectively. The springs are compressed and deformation of the springs acts to buffer, therefore, swaying amplitude of the car is decreased, and the guide shoe can roll normally.
Description
Technical Field
The utility model relates to an elevator gyro wheel guide shoe, mainly used speed 1m/s is less than or equal to V and is less than or equal to 5 m/s medium and high-speed elevator.
Background
The roller guide shoe adopts the roller as a lift car or a part for running and guiding a counterweight as the name implies, and the roller is in rolling contact, so that the friction resistance between the roller and a guide rail is reduced, the energy consumption is reduced, the power is saved, the vibration and the noise are reduced, and the roller guide shoe is generally used for high-speed elevators and mining elevators with the speed of more than or equal to 2 m/s.
The contact surface of the roller guide shoe to the guide rail is not inclined, the roller is in uniform vertical contact with the guide rail surface on the whole rim width, and when the lift car runs, the three rollers roll simultaneously, so that the stable running of the lift car can be kept.
Disclosure of Invention
The utility model aims at providing a simple structure, processing is convenient, operates steadily, and it is convenient to maintain, and the low price is applicable to the gyro wheel guide shoe of well, high-speed ladder.
The utility model adopts the technical scheme as follows: a roller guide shoe comprises a shoe frame, a roller shaft, a control rod, a spring, a guide rod, a limit nut, a limit bolt and a dust cover; the three rollers are respectively fixed on the control rod through roller shafts, the control rod is L-shaped, the long end of the control rod is in contact with the spring, when the rollers are stressed, the long end of the control rod presses the spring to buffer, the short end of the control rod is provided with a limit bolt which can be adjusted through threads, when the rollers shake, the maximum shaking offset of the rollers can be limited, and the offset of the rollers is ensured to be within a required range; the opening distance of the two rollers is adjusted by adjusting the compression amount of the limiting nut to adjust the opening distance of the spring in advance, so that the balance of the initial pressure of the contact between the rollers and the guide rail can be controlled, when the lift car is unbalanced in stress and shakes, any roller can slightly swing around points A, B and C after being stressed and deformed, the spring is compressed, the deformation of the spring plays a role in buffering, the shaking amplitude of the lift car is reduced, and the guide shoe can normally roll; the guide rod is provided with a limiting nut capable of adjusting the deformation of the spring, and the long end of the control rod is in contact with the spring penetrating through the guide rod.
The roller is made of polyurethane through injection molding, the weight is reduced, the roller has high strength and wear resistance, rubber with the thickness of 15mm is wrapped on the roller, and the roller is simple to form and low in price and can meet the requirements of stability of elevator operation and noise reduction.
Drawings
Fig. 1 is a schematic three-dimensional structure diagram of a roller guide shoe-RG 80 according to the present invention; wherein,
1-boot rack, 2-roller, 3-roller shaft, 4-control rod, 5-spring, 6-guide rod, 7-limit nut, 8-limit bolt and 9-dust cover.
Detailed Description
As shown in fig. 1, the utility model mainly comprises a boot frame 1, a roller 2, a roller shaft 3, a control rod 4, a spring 5, a guide rod 6, a limit nut 7, a limit bolt 8 and a dust cover 9; the roller 2 is fixed on a control rod 4 by a roller shaft 3, the control rod 4 is fixed on the boot frame 1 by a bolt, a limit bolt 8 is arranged at the short end of the control rod 4, a spring 5 penetrates on a guide rod 6, the deformation of the spring is fixed by a limit nut 7, the guide rod 6 is fixed on the boot frame 1, and a dust cover 9 is also fixed on the boot frame 1 by a bolt.
When the car was when using, when the atress inequality produced and rocked, the gyro wheel of arbitrary atress will pass through control lever compression spring, and the deformation of spring makes the gyro wheel lead the impact that boots received and alleviates, and in reasonable stress range, the gyro wheel is led boots and not only can be guaranteed normal operation, can cushion rocking of car in addition, increases the travelling comfort that the passenger took.
