The invention relates to the technical field of guide rails, in particular to an elevator guide rail which comprises a base, a guide rail body is fixedly mounted in the middle of the base, rails are arranged on the two sides of the middle of the guide rail body, device blocks are symmetrically and fixedly mounted at one end of the base, and device cavities are formed in the device blocks; the two rails are in close contact with pulleys, and a guide pipe is embedded in the guide rail body. The pulley is lubricated through sliding of the pulley on the rail, the pulley is cooled through cooling liquid when the pulley is located on each layer, when the temperature of the pulley is too high, equipment is damaged, an alarm is given through a memory alloy wire, and when the pulley is out of control or the running speed is too high, the pulley is buffered through a friction plate, and the safety of an elevator is protected.
Description
technical field [0001] The invention relates to the technical field of guide rails, in particular to an elevator guide rail. Background technique [0002] The elevator guide rail is an elevator component composed of steel rails and connecting plates. It is divided into car guide rails and counterweight guide rails. From the cross-sectional shape, it can be divided into three types: T-shape, L-shape and hollow. While the guide rail plays a guiding role, it also bears the impact force of the car and elevator braking, and the impact force of the safety gear during emergency braking. The magnitude of these forces is related to the load and speed of the elevator, so guide rails should be selected according to the speed and load of the elevator. It is usually called the car guide rail as the main rail, and the counterweight guide rail as the auxiliary rail. [0003] The existing patent (notification number: CN112478983A) is an elevator guide rail, including a base, a rail waist...
