Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
It will be understood that when an element is referred to as being "mounted on" another element, it can be directly mounted on the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
When the elevator runs up and down, the elevator guide mechanism plays a role in guiding the motion of the elevator, and a reference component used for guiding in the elevator guide mechanism is an elevator guide rail.
In practical applications, the counterweight system usually has a structure that is wider in the Y direction and narrower in the X direction, which causes the unbalance loading force Fy exerted on the elevator guide rails by the counterweight system to be much greater than Fx when the elevator guide rails are applied to the counterweight system. Particularly, under the earthquake working condition, because an approximately 3-5 mm running clearance exists between the counterweight system and the top of the guide rail and almost no clearance exists between the counterweight system and the guide surface of the elevator guide rail, the impact force of the counterweight system on the guide rail in the Y direction under the earthquake working condition is far larger than that in the X direction. Therefore, the design of the cross section of the elevator guide rail needs to improve the deformation resistance in the Y direction. Wherein the direction perpendicular to the bottom surface is defined as the Y-direction, while the direction perpendicular to the direction in which the elevator guide rails extend and the Y-direction is defined as the X-direction.
Practical application shows that under the condition that the areas of the cross sections along the X direction are the same, the bending strength of the closed elevator guide rail structure with the cavity is superior to that of the elevator guide rail with the open structure; in addition, closed hollow elevator guide rails with thinner wall thicknesses are currently used to save material costs. However, the applicant has found that, when the wall thickness is reduced, the two side surfaces of the elevator guide rail have mechanical weak points, and the bearing capacity of the mechanical weak points is relatively weak under the action of the forces Fx and Fy, and the deformation resistance is to be improved.
Thus, the present invention provides an elevator guide rail 10, referring to fig. 1 and 2, the elevator guide rail 10 having two oppositely disposed side surfaces 11 and a bottom surface 12 connecting the two side surfaces 11; the elevator guide rail 10 has a cavity 18 therein; the bottom surface 12 is recessed toward the cavity 18 to form a support portion 13, and the support portion 13 abuts against the side surface 11.
By arranging the supporting part 13, the supporting part 13 is abutted against the side surface 11 of the elevator guide rail 10, so that the stress strength of the side surface 11 is obviously enhanced, the deformation resistance of the side surface 11 is enhanced, the deformation resistance of the elevator guide rail 10 is further improved, and the safety performance and the stability of the elevator guide rail 10 are improved. More preferably, the supporting part 13 is directly formed by sinking the bottom surface 12 into the cavity 18, and the forming mode of the supporting part 13 is simple, so that the structure of the elevator guide rail 10 is simplified, the processing steps are simplified, and the cost is greatly reduced.
Preferably, referring to fig. 1 and 2, the supporting portion 13 is a convex portion that is recessed from the bottom surface 12 toward the cavity 18 and extends toward the inside of the cavity 18, two sides of the convex portion respectively abut against the side surfaces 11 at two sides to enhance the stress strength of the side surfaces 11, and the convex portion is not connected with the side surfaces 11, so that the forming step of the supporting portion 13 is simplified, and the processing cost is reduced.
Further, with continuing reference to fig. 1 and fig. 2, each side surface 11 includes a guiding surface 111 and a supporting surface 112 connected to each other, and the guiding surface 111 and the supporting surface 112 are smoothly transited and connected; the bottom surface 12 is connected with two supporting surfaces 112, and the supporting parts 13 are respectively abutted against the joints of the guiding surfaces 111 and the supporting surfaces 112 at two sides. It will be appreciated that the junction between the guide surface 111 and the support surface 112 has a weak mechanical point, and particularly when the guide surface 111 and the support surface 112 are angled, the junction is more susceptible to deformation when the side surface 11 is subjected to Y-direction and X-direction impact forces. In this embodiment, the support portion 13 is abutted against the joint between the guide surface 111 and the support surface 112, so that the deformation resistance of the joint can be significantly enhanced, and the deformation resistance of the entire elevator guide rail 10 can be enhanced. Of course, in other embodiments, the abutting position of the supporting portion 13 and the side surface 11 is not limited to the joint of the guiding surface 111 and the supporting surface 112, and may be other positions with relatively weak mechanics.
The elevator guiding mechanism 100 further comprises a pressing guide plate and a guide rail bracket, wherein the pressing guide plate is used for pressing and limiting the elevator guide rail 10 on the guide rail bracket so as to fix the elevator guide rail 10. In order to facilitate the installation of the elevator guide rail 10, an included angle exists between the guide surface 111 and the support surface 112, so that the elevator guide rail 10 has a position which can be used for being matched with the pressure guide plate and the guide rail bracket for positioning and limiting, in other words, the support surface 112 is bent relative to the guide surface 111, so that the support surface 112 is an installation position for being matched with the installation and positioning of the pressure guide plate, the pressure guide plate can be pressed on the support surface 112, and meanwhile, the bottom surface 12 is pressed against the guide rail bracket, and the elevator guide rail 10 is installed in a positioning mode.
More preferably, the angle α between the guide surface 111 and the support surface 112 is in the range of 90-120 °, in which the larger the moment of inertia and the bending modulus of the elevator guide rail 10 in the Y-direction, and thus the larger the resistance of the elevator guide rail 10 to deformation in the Y-direction.
Further, referring to fig. 2, the bottom surface 12 is disposed adjacent to the supporting surface 112. In the case where the total height of the transverse cross section (cross section in the X direction) of the elevator guide rail 10 in the Y direction is constant, the higher the height of the guide surface 111 in the Y direction, the stronger the bending resistance of the elevator guide rail 10 in the Y direction, and it is understood that the higher the height of the guide surface 111 in the Y direction, the larger the area of the guide surface 111 for bending resistance, and thus the stronger the bending resistance of the elevator guide rail 10 in the Y direction. When the bottom surface 12 and the support surface 112 are closely attached to each other, the height of the guide surface 111 in the Y direction is the highest, and the bending strength of the elevator guide rail 10 in the Y direction is the strongest in the case where the total height of the elevator guide rail 10 is constant.
Of course, in other embodiments, there may be a space between the bottom surface 12 and the supporting surface 112, for example, in the elevator guide rail 10 shown in fig. 1, there may also be a space between the bottom surface 12 and the supporting surface 112, the bottom surface 12, the supporting surface 112 on the corresponding side and the side surface 11 of the supporting portion 13 are enclosed to form a positioning cavity 14, and along the Y direction, the upper and lower surfaces of the positioning cavity 14 are respectively abutted with the press guide plate and the guide rail bracket in a matching manner, so as to realize the positioning and installation limit of the elevator guide rail 10.
Preferably, referring to fig. 2, when the bottom surface 12 and the supporting surface 112 are closely arranged, the side surface 11 of the supporting portion 13 is also closely abutted with the joint of the guiding surface 111 and the supporting surface 112, the supporting portion 13 and the joint are abutted surface to surface, the larger the area of mutual abutment is, the larger the supporting force of the supporting portion 13 to the joint is, and the more stable the supporting is, so that the joint has stronger deformation resistance.
Referring to fig. 2, preferably, the side of the supporting surface 112 connected to the bottom surface 12 is turned away from the bottom surface 12 to form a first turned edge 15, and the first turned edge 15, the supporting surface 112 and the guiding surface 111 are surrounded to form a limiting groove 16. When the pressure guide plate is pressed against the support surface 112, the portion of the pressure guide plate that is used to press against the support surface 112 is retained within the retention slot 16, and during assembly tightening, the retention slot 16 helps to locate the pressure guide plate and helps to prevent the pressure guide plate from sliding off the support surface 112 in the X-direction.
Further, referring to fig. 1 and 2, the elevator guide rail 10 is integrally formed. The integrally formed elevator guide rail 10 has the advantages of better overall performance and stronger bending strength of the structure, so that the stability of the elevator guide rail 10 is better, and the integrally formed elevator guide rail 10 is beneficial to simplifying the processing steps of the elevator guide rail 10, thereby reducing the processing cost.

The first connecting piece 20 and the second connecting piece 30 are matched and positioned and are connected with two adjacent guide rail units 101, and a plurality of segmented guide rail units 101 are spliced into a complete elevator guide rail 10, so that the manufacturing difficulty of the elevator guide rail 10 is simplified; moreover, in the application, the first connecting piece 20 and the second connecting piece 30 are manufactured in a split mode with the elevator guide rail 10, the first connecting piece 20 and the second connecting piece 30 can move and adjust relative to the elevator guide rail 10 to improve the positioning accuracy of the guide rail unit 101 during assembly, so that the adjacent guide rail units 101 are connected stably, the first connecting piece 20 and the second connecting piece 30 are manufactured in a split mode with the elevator guide rail 10, the structure of the elevator guide rail 10 is simplified, and the structural design difficulty and the structural cost are reduced.
It should be noted that the first connecting member 20 and the second connecting member 30 may be connected directly, for example, the second connecting member 30 is provided with a connecting portion, and the connecting portion can penetrate through the bottom surface 12 of the elevator guide rail 10 and is connected with the first connecting member 20. Of course, the first connecting member 20 and the second connecting member 30 may be connected by the fastening member 200.

Of course, in other embodiments, the specific structure of the first connecting member 20 is not limited to the above. In addition, the specific structural shape of the first connecting member is not limited to the above or shown in the drawings, and may be other shapes.
Wherein the fastening member 200 is connected to the first connecting member 20 by riveting, welding, or clipping. And the fastener 200 may be a nut, a bolt, or the like fastening structure.

Thereby contributing to further increase in the bending strength of the elevator guide rail 10 in the Y direction. Of course in other embodiments the first connecting element 20 may not abut the top of the elevator guide rail 10.
Further, both sides of the first connecting member 20 in the X direction abut against the guide surfaces 111 on both sides of the elevator guide rail 10, thereby contributing to further enhancing the bending strength of the elevator guide rail 10 in the X direction. Of course, in other embodiments, the first connecting member 20 may not abut against the guide surface 111.
Referring to fig. 1 and 5, a positioning structure is disposed between the bottom surface 12 of the rail unit 101 and the second connecting member 30, and the positioning structure is used for matching with and positioning the rail unit 101. When two adjacent guide rail units 101 are installed, firstly, the two guide rail units 101 are respectively installed on the second connecting piece 30, and the installation positions of the guide rail units 101 are limited through the positioning structure, so that the two adjacent guide rail units 101 can be accurately connected, the installation dislocation of the two adjacent guide rail units 101 is prevented, and the assembly precision of the guide rail units 101 is improved.
