Problems solved by technology

[0003] Traditional elevator guide rail fixing methods, such as figure 1 and figure 2 As shown, the pressure guide plate that fixes the elevator guide rail is rigidly fixed, and there are two reference planes, namely the Z-axis direction and the X-axis direction. Once the fixing screws are a little loose, the pressure guide plate will soon lose its fixation and connection with this section of the elevator guide rail. Positioning effect, the specific reasons are as follows: the pressure guide plate is pressed on the inclined surface of the guide rail blade, and under the action of the fixing screw pressing force on the other side, the elevator guide rail will quickly move in the X-axis direction to the side where the fixing screw is loose, resulting in The fixing and positioning of this section of elevator guide rail will lose its effect, which will increase the workload of elevator maintenance, and may even cause safety accidents
Moreover, when people or goods get on and off the elevator car, a horizontal impact force in the X-axis direction will be generated, and this impact force will be indirectly transmitted to the elevator guide rails through the elevator car to make a push in the X-axis direction, and the elevator will move at high speed. During operation, due to the vibration of the elevator car and the elevator guide rails, the impact force in the X-axis direction will also be indirectly generated, which will accelerate the loosening of the fixing screws of the pressure guide plate that fixes the elevator guide rails, resulting in the displacement of the elevator guide rails, especially for high-speed and high-rise elevators. The elevator guide rails of the car are more prone to displacement of the elevator guide rails, which can induce elevator safety accidents

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as image 3 and figure 2 , 4 As shown, the elevator guide rail fixing part for high-speed and high-rise elevator cars of the present invention includes a pressure guide plate 1 that is crimped on the guide rail vanes on both sides of the elevator guide rail, and one end of the pressure guide plate 1 is crimped on the corresponding side. The bottom of the pressure guide plate 1 is provided with a positioning plate 2, one side of the positioning plate 2 is against the outer edge of the corresponding side guide rail blade, and the other side of the positioning plate 2 is upward The other end of the pressure guide plate 1 is pressed against the inner side of the tilted side of the positioning plate 2. If the thickness of the elevator guide rail guide rail blade is thicker, the positioning plate 2 is against the outer edge of the corresponding side guide rail...

Abstract

The invention discloses an elevator guide rail fixing component used for high-speed and high-rise elevator cars. Positioning plates located on both sides of the elevator guide rail are arranged at the bottom of the pressure guide plate, which can prevent the movement of the elevator car guide rail in the X-axis direction. The bottom of the fixing bolt of the fixed pressure guide plate is sleeved with a fixed collar, and a strong compression elastic washer is nested in the fixed collar, so that the elevator guide rail of the elevator car can freely expand and contract in the vertical Z-axis direction under the action of natural force, ensuring that the building The safety of objects and elevator shaft installation parts and elevator guide rails, as well as the assembly accuracy of the elevator, ensure that the elevator guide rails can withstand impulse and braking forces, especially for high-speed, high-rise elevator cars, and have a good application prospect.

Description

technical field [0001] The invention relates to the technical field of elevator guide rails, in particular to an elevator guide rail fixing component used for high-speed, high-rise elevator cars. Background technique [0002] The elevator guide rail is an important part of the elevator. It is fixedly installed in the elevator shaft. The elevator guide rail needs to overcome the force in two directions. The vertical direction (up and down) is the Z-axis direction, and the horizontal direction (left and right) is the X-axis direction. , the elevator guide rail is fixed on the wall of the elevator shaft. In addition to overcoming the gravity and acceleration of the person or cargo in the Z-axis direction, it is also necessary to overcome the impact force in the X-axis direction when the person or cargo gets on and off the elevator car. Moreover, It is also necessary to overcome the effects of thermal expansion, cold contraction and wind force of the elevator shaft wall. [000...
