Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to a rolling guide rail pressing code of an elevator and an elevator guide rail installation structure. Background Art

[0002] Elevator guide rails are an essential part of elevators, and the reliability of elevator guide rail fixation directly affects the performance and operational safety of elevators. Now, with the continuous development of the economy, more and more high-rise buildings are emerging, and the application of high-speed elevators is becoming more and more extensive. As the height of buildings continues to increase, due to various reasons such as building shrinkage and geological aspects, high-rise buildings will have problems such as settlement during use, which will cause the guide rails to deform and affect the quality of elevator operation. To solve this problem, the holding force between the guide rail pressure code and the elevator guide rail should be small, which requires that during the building settlement process, the guide rail pressure code and the elevator guide rail can be relatively displaced, so that the building settlement will not act on the elevator guide rail through the guide rail pressure code, and the elevator guide rail will not be deformed due to the building settlement.

[0003] There are many types of common guide rail pressure gauges, such as cast guide rail pressure gauges, forged guide rail pressure gauges, etc. However, the holding force of these guide rail pressure gauges is too large and they cannot move relative to the elevator guide rails, so it is easy for the guide rails to bend and deform when the building settles. This will affect the quality and comfort of elevator operation, and also bring safety risks.

[0004] Therefore, there is a need for further improvement of the existing guide rail code pressing.

[0005] The information disclosed in the background part of the present invention is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0063] In order to more clearly illustrate the positional relationship of each structure, a three-dimensional rectangular coordinate system is added to the drawings, wherein the x-axis and y-axis are axes on the horizontal plane, the positive direction of the y-axis is the direction in which the elevator guide rail bracket 500 points to the T-shaped elevator guide rail 100, and the z-axis is the vertical axis, the positive direction of the z-axis is vertically upward, the x-axis in different figures points to the same direction, the y-axis points to the same direction, and the z-axis points to the same direction. The y-axis direction is the first direction, and the x-axis direction is the second direction.

[0064] The rolling guide rail pressure code of the elevator of the utility model implementation scheme can be applied to the T-shaped elevator guide rail 100, such as Figure 1 As shown, the T-shaped elevator guide rail 100 includes a head 110 and a waist 120, wherein the head 110 is a portion close to the side wall of the hoistway, the waist 120 is a portion away from the side wall of the hoistway, and the waist 120 is perpendicular to the head 110, and the waist 120 extends from the middle of the head 110 in a direction away from the elevator guide rail bracket 500 (i.e., the positive direction of the y-axis).

[0066] Combine the following Figures 2 to 9 The rolling guide rail code pressing of the elevator according to the implementation scheme of the utility model is explained.

[0067] like Figure 2 and Figure 3 As shown, one T-shaped elevator guide rail 100 corresponds to two elevator rolling guide rail pressure codes, the two elevator rolling guide rail pressure codes are symmetrically arranged, and the first rolling components 300 of the two elevator rolling guide rail pressure codes are arranged at positions close to each other.

The outer peripheral surface of the first boss 222 at one end close to the side wall of the well has a notch 224, and the mounting groove 216 of the clamping plate 211 has a shape corresponding to the notch 224 (see FIG. 21 for details). Figure 6 ), so that the first boss 222 can be installed in the mounting groove 216 of the clamping plate 211 of the main body plate 210, and ensure that the stud 220 will not rotate relative to the clamping plate 211 of the main body plate 210.

[0082] The second boss 223 is cylindrical and extends outward from the middle of the stud body 221 in the radial direction (i.e., the diameter of the second boss 223 is larger than the diameter of the stud body 221). The first boss 222 is located on the side of the second boss 223 close to the side wall of the well, and the diameter of the first boss 222 is larger than the diameter of the second boss 223.
