The paper analyzes the importance of the guide rail from the safety and warmth of the elevator. The types of the press plate of the elevator guide rail are divided into three categories: solid guide rail rail plate, counterweight hollow guide rail rail plate and escalator guide rail rail plate.
The rail pressing plate of elevator guide rail is an elevator component composed of rail and connecting plate, which is divided into car guide rail and counterweight guide rail. It can be divided into T-shape, L-shape and hollow shape. When the guide rail plays a guiding role, it receives the impact force of car and elevator braking, and the impact force of emergency braking of safety tongs. The magnitude of these forces is related to the load and speed of the elevator, so the guide rail should be selected according to the speed and load mass of the elevator. Usually called the car guide rail as the main rail, counterweight guide rail as the auxiliary rail.
Brief introduction of elevator guide rail track pressing plate:
1¡¢ The elevator guide rail rail pressing plate is a safe rail for the elevator to travel up and down the shaft. The guide rail device is on the shaft wall, and is fixed and connected to the shaft wall by the guide rail frame and guide rail bracket. The commonly used guide rail of elevator is "t" shape guide rail. Strong rigidity, high reliability, safety and low price. The plane of guide rail must be lubricated without obvious uneven surface. Since the guide rail is the guide shoe on the elevator car and the flat tongs pass through the rail, the clearance must be ensured when installing. At the same time, when the elevator appears overspeed accident, the guide rail should accept the responsibility of stopping the elevator, so its rigidity can not be ignored.
2¡¢ The elevator guide rail is two or more vertical or inclined rigid rails installed in the elevator shaft or between floors to ensure the car and counterweight to move up and down along it, to ensure that the escalator and the escalator step move along it, so as to provide guidance for the installation of elevator car, counterweight or ladder. According to the definition of the guide rail, the guide rail rail pressing plate is an important reference component of vertical elevator, escalator and escalator. It controls the running track of elevator car, escalator and escalator, and ensures the transmission of operation signal. It is also an important part that touches the safety and operation quality of the elevator
Analysis of the importance of track plate:
Haian Sanyi metal knows that the elevator guide rail provides guidance for the installation of the car and counterweight when the elevator is running, and also plays a supporting role in the safe clamping. It is an important part of the elevator system.
The following analyzes the importance of the guide rail from the safety and warmth of the elevator.
1¡¢ Safety. The main factor that affects the safety of elevator is the material of guide rail. If the guide rail material is too hard or uneven (part of it is too hard), the clamping will not get enough friction when the clamp is braked, which will lead to brake failure, which is the most serious working condition of elevator car falling. The guide rail should also have enough strength to ensure the support of the car and impact force when the safety tongs brake.
2¡¢ Warmth. There are several factors that affect the warmth of the elevator
1. Connection accuracy of guide rail: the connection accuracy of solid guide rail is guaranteed by the end size of guide rail and symmetry of male and female tenon; the connection accuracy of hollow guide rail and escalator guide rail is guaranteed by the end dimension and shape and position tolerance of guide rail, and the connection accuracy of guide rail directly affects the stability and warmth of elevator operation.
2. Guide surface roughness: the guide surface roughness directly affects the smooth operation of guide shoe on the guide surface, also affects the storage of smooth oil, thus affecting the operation quality of the car.
3. Straightness and distortion of guide rail: bending and twisting at any point on the guide rail will give a side force to the car, which will affect the linear motion of the car up and down, and make the car shake. With the progress of the elevator speed, the car will vibrate and affect the warmth.
