Roller guide shoe with auxiliary braking function

Abstract

The invention relates to a roller guide shoe with an auxiliary braking function, and belongs to the technical field of elevators. The roller guide shoe with the auxiliary braking function is providedwith a guide shoe seat; adjusting devices which are connected to the guide shoe seat through bolts are symmetrically arranged on the guide shoe seat; each adjusting device is connected with a spring supporting rod; one side, opposite to each adjusting device, of the corresponding spring supporting rod is connected with a braking roller which is made of an elastic material; each braking roller is connected with an electric control braking motor which is arranged on a mounting plate; a longitudinal roller which is perpendicular to the plane on which the braking rollers are positioned is connected between the two adjusting devices through a bolt; and the mounting plate which is fixed to the guide shoe seat and provides supporting for the electric control braking motor is arranged below the electric control braking motor. The roller guide shoe with the auxiliary braking function has the benefits that braking values G are uniformly distributed and a braking curve is stabilized, so that thesafety and comfort of personnel in an elevator cage are improved; the rollers are of a spring bearing type, so that the taking comfort is ensured; and the electric control motor brakes by holding a brake, an oil pressure loop is avoided, and the structure is compact.

Description

technical field [0001] The invention relates to a roller guide shoe with an auxiliary braking function, which belongs to the technical field of elevators. Background technique [0002] The guide shoe is a kind of guiding device arranged between the elevator guide rail and the car. It can fix the car on the guide rail and let the car move up and down along the established track. [0003] With the development of social science and technology, the speed of elevators continues to increase, which has brought a series of problems. Among them, the safety of people in the car is the most important. However, the braking G value is relatively large and the distribution is uneven, which is easy to cause harm to the human body. In order to reduce the G value and achieve uniform distribution, a new brake system was developed by referring to the working principle of the electronic parking brake of the car. The new type of roller guide shoe with braking function, through pre-adjustment an...

Problems solved by technology

[0003] With the development of social science and technology, the speed of elevators continues to increase, which has brought a series of problems. Among them, the safety of people in the car is the most important. However, the braking G value is relatively large and the distribution is uneven, which is easy to cause harm to the human body. In order to reduce the G value and achieve uniform distribution, a new brake system was developed by referring to the working principle of the electronic parking brake of the car. The new type of roller guide shoe with braking function, through pre-adjustment and calibration, can obtain a good braking curve when using this guide shoe in the high-speed elevator system, which can meet the needs of current use, improve the comfort of people in the car, and can effectively increase the number of elevators. factor of safety
