Description

Technical Field

[0001] This application relates to the field of elevators, and in particular to a fixing structure for elevator components and an elevator guide rail bracket. Background Technology

[0002] Currently, elevators are being used more and more widely. Elevators use guide rails to guide the elevator car to move up and down smoothly.

[0003] Elevator guide rail brackets serve to support and fix the guide rails in the elevator car. Since the verticality and stability of the guide rails affect the operation of the elevator, the general elevator installation process usually involves welding the guide rail brackets after adjusting the guide rails.

[0004] While welding can achieve the purpose of fixing and preventing loosening, if the guide rail needs to be readjusted, the support body must be damaged. Furthermore, welding will affect the aesthetics and structure of the elevator and is prone to causing fire. Summary of the Invention

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0050] Unless otherwise defined, 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 application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] In one embodiment, such as Figures 1 to 7 As shown, an elevator component 10 includes a first component 11 and a second component 12. At least a portion of the structures of the first component 11 and the second component 12 are stacked on top of each other. The first component 11 has a first mounting hole 111, and the second component 12 has a second mounting hole 121 corresponding to the first mounting hole 111.

[0052] When the first component 11 and the second component 12 are fitted together, a portion of the first mounting hole 111 and a portion of the second mounting hole 121 are connected to each other, so that the first mounting hole 111 and the second mounting hole 121 form insertion holes on the two components.

[0053] The first component 11 and the second component 12 are connected by a fixing structure 20. The fixing structure 20 includes a screw 21, a limiting head 22 and a screw connector 23. The limiting head 22 is located at one end of the screw 21, and the limiting head 22 gradually tapers from the end away from the screw 21 to the outer periphery of the end connected to the screw 21. The screw connector 23 is threadedly connected to the screw 21.

[0054] The end of the screw 21 away from the limiting head 22 passes through the overlapping part of the two mounting holes, so that the first component 11 and the second component 12 are locked on the limiting head 22, and the first component 11 and the second component 12 are clamped and fixed by the screw connector 23 cooperating with the limiting head 22.

[0055] The screw 21 passes through the overlapping part (insertion hole) of the two mounting holes, and then the limiting head 22 is wedged into the insertion hole. Then the screw connector 23 is tightened onto the screw 21. At this time, the side wall of the limiting head 22 can contact the overlapping part of the two mounting holes. Through the friction between the limiting head 22 and the first mounting hole 111 and the second mounting hole 121, as well as the mutual cooperation between the screw connector 23 and the limiting head 22, it can prevent the relative torsion between the first component 11 and the second component 12, as well as the displacement along the radial direction of the limiting head 22.

[0056] The fixing structure 20 in this application requires no welding, is suitable for various installation occasions, has a simple structure, is easy to install, is aesthetically pleasing and concise, and has strong practicality. When fastened with the screw connector 23, the installation accuracy can be verified using a torque wrench, facilitating standardized inspection. Furthermore, after tightening the screw connector 23, a significant lateral tension force can be applied, increasing the fixing strength of the fixing structure 20.

[0057] The stud has external threads, and the screw connector 23 has a threaded hole that mates with the external threads of the stud. To facilitate screwing the screw connector 23 onto the stud, the outer contour of the cross-section of the screw connector 23 is polygonal. In this embodiment, the outer contour of the cross-section of the screw connector 23 is hexagonal.

[0058] In another embodiment, such as Figures 3 to 5 As shown, the first mounting hole 111 and the second mounting hole 121 are intersected and overlap in a quadrilateral shape;

[0059] Wherein, at least part of the extension path of the first mounting hole 111 and the extension path of the second mounting hole 121 are straight segments, and the straight segments of the extension path of the first mounting hole 111 and the straight segments of the extension path of the second mounting hole 121 are set at an oblique angle or perpendicularly.

[0060] The sidewall of the limiting head 22 has two opposite first side surfaces 221 and two opposite second side surfaces 222. Each first side surface 221 contacts the two opposite sides of the first mounting hole 111 at the overlap, and each second side surface 222 contacts the two opposite sides of the second mounting hole 121 at the overlap.

[0061] In another embodiment, the limiting head 22 passes sequentially through the first mounting hole 111 and the second mounting hole 121. The distance between the two opposite sides of the first mounting hole 111 at the overlapping point is L1, and the distance between the two opposite sides of the second mounting hole 121 at the overlapping point is L2. When L1 equals L2, the included angle between the two first side surfaces 221 is greater than the included angle between the two second side surfaces 222. This design can increase the lateral tension force of the limiting head 22.

[0062] The limiting head 22 has a length direction. One end of the limiting head 22 facing away from the screw 21 is the first end, and the other end is the second end. Both first side surfaces 221 and both second side surfaces 222 gradually approach each other from the first end to the second end. The second end of the limiting head 22 passes through the first mounting hole 111 and the second mounting hole 121 in sequence.

[0063] like Figure 5 As shown, when the distance between the two opposite sides of the first mounting hole 111 along the extension path and the distance between the two opposite sides of the second mounting hole 121 along the extension path are both C, C is less than the maximum width of the limiting head 22 (e.g., Figure 5 (A or B in the text) is greater than the minimum width of the limit head 22 (e.g., A or B in the text). Figure 5 (D or E in the text). Wherein, the length of the limiting head 22 along its own axial direction is the length of the limiting head 22, and the width of the limiting head 22 is perpendicular to the length of the limiting head 22.

[0064] Of course, in other embodiments, or when L1 is greater than L2, the included angle between the two first side surfaces 221 is equal to or less than the included angle between the two second side surfaces 222.

[0065] In another embodiment, such as Figure 8 and Figure 9 As shown, the included angle between the two first side surfaces 221 is 0 degrees to 10 degrees. When the included angle between the two first side surfaces 221 is too large, it will reduce the area of ​​contact between each first side surface 221 and the two opposite sides of the first mounting hole 111 along the extension path, thereby reducing the friction between the limiting head 22 and the inner wall of the insertion hole, and reducing the friction between the fixing pin and the inner wall of the insertion hole. This can easily lead to the problem of relative torsion between the first component 11 and the second component 12.

[0066] The included angle between the two second side surfaces 222 is 0 degrees to 10 degrees. If the included angle between the two second side surfaces 222 is too large, it will reduce the area of ​​contact between each second side surface 222 and the two opposite sides of the second mounting hole 121 along the extension path, thereby reducing the friction between the limiting head 22 and the inner wall of the insertion hole, which may easily cause the first part 11 and the second part to twist against each other.

[0067] When the limiting head 22 is inserted into the intersection of the first mounting hole 111 and the second mounting hole 121, the sides that are inclined relative to the axial direction of the limiting head 22 can form a self-locking mechanism. α is the angle between the centerline of the first side 221 (located at the first side 221, connecting the center of the first end to the centerline of the second end) and the axis of the limiting head 22; β is the angle between the centerline of the second side 222 (located at the second side 222, connecting the center of the first end to the centerline of the second end) and the axis of the limiting head 22; the coefficient of friction of the material of the limiting head 22 is μ; and the wedge force is E (reference). Figure 10 ).

[0068] Provided that tanα < μ and / or tanβ < μ, the limiting head 22 forms a self-locking mechanism, and will not exit the insertion hole without a vertical anti-wedge force. α and β are related to each other according to the depth of the first mounting hole 111 and the second mounting hole 121.

[0069] Preferably, the included angle between the two first side surfaces 221 is 0 degrees to 6 degrees;

[0070] The angle between the two second side faces 222 is 0 degrees to 6 degrees.

[0071] In another embodiment, the number of first mounting holes 111 is at least two, and the number of second mounting holes 121 corresponds to the number of first mounting holes 111; the number of fixing structures 20 corresponds to the number of insertion holes to prevent relative movement between the first component 11 and the second component 12.

[0072] Preferably, when there are at least two first mounting holes 111 and second mounting holes 121, at least two sets of fixing structures 20 are arranged in opposite directions. That is, when the first component 11 is above the second component 12, at least one set of fixing structures 20 has a limiting head 22 above and a screw connector 23 below, and another set of fixing structures 20 has a limiting head 22 below and a screw connector 23 above.

[0073] In this embodiment, there are two of each of the first mounting hole 111, the second mounting hole 121, and the fixing structure 20. Of course, in other embodiments, there may be three or more of the first mounting hole 111, the second mounting hole 121, and the fixing structure 20.

[0074] Preferably, the extension path of the first mounting hole 111 and the extension path of the second mounting hole 121 are at a 90-degree angle (i.e., Figure 5 In the middle (θ), the cross-section of the socket is roughly rectangular, and the corresponding cross-section of the limiting head 22 is rectangular.

[0075] To further prevent relative movement between the first component 11 and the second component 12, referring to one embodiment, the extension paths of at least two first mounting holes 111 are arranged obliquely or perpendicularly, and the extension paths of at least two second mounting holes 121 are arranged obliquely or perpendicularly.

[0076] Preferably, the included angle between the extension paths of the two first mounting holes 111 is 20 degrees to 90 degrees;

[0077] The included angle between the extension paths of the two second mounting holes 121 is 20 degrees to 90 degrees.

[0078] Most preferably, the included angle between the extension paths of the two first mounting holes 111 is 90 degrees;

[0079] The included angle between the extension paths of the two second mounting holes 121 is 90 degrees.

[0080] In another embodiment, such as Figure 6 and Figure 7 As shown, the limiting head 22 has a deformation groove 223 that absorbs its own deformation. The limiting head 22 is made of rigid material. The deformation groove 223 can make the limiting head 22 have a certain elasticity. When the limiting head 22 is wedged into the first mounting hole 111 and the second mounting hole 121, the limiting head 22 is locally deformed by force, so that the limiting head 22 and the overlapping part change from the line contact state before tightening to the surface contact state after tightening, thereby effectively increasing the contact area and improving the friction.

[0081] Along the axial direction of the fixing pin, the deformation groove 223 can be closed at one end and open at the other end;

[0082] Alternatively, the deformation groove 223 can be a through groove that passes through the fixing pin 22.

[0083] In this embodiment, such as Figure 11 As shown, the cross-section of the deformation groove 223 is circular. The width of the first side 221 is A (the width of the first side 221 is perpendicular to the length of the limiting head 22), and the width of the second side 222 is B (the width of the second side 222 is perpendicular to the length of the limiting head 22), and A≠B. The shortest distance from the geometric center of the deformation groove 223 to each of the first side 221 and each of the second side 222 is equal (i.e., Figure 12 In this context, X = Y = Z). Of course, in other embodiments, the cross-sectional shape of the deformation groove 223 is not strictly limited, and the cross-section of the deformation groove 223 can also be square or other shapes.

[0084] Referring to one embodiment, such as Figure 7 As shown, the screw connector 23 has an extension 231 extending toward the limiting head 22. When the screw connector 23 is screwed onto the screw 21, the extension 231 abuts against the first component 11 or the second component 12, and a receiving groove for receiving the limiting head 22 is formed between the extension 231 and the screw 21.

[0085] The screw 23 is fastened to the screw 21, changing the contact between the hollow limiting head 22 and the overlapping area from line contact to surface contact. The limiting head 22 deforms locally, making it easier to lock into the receiving groove. The end face of the limiting head 22 facing the screw 21 remains within the receiving groove throughout the fastening process.

[0086] To facilitate the processing of the extension 231 and simultaneously satisfy the contact area between the extension 231 and the first component 11 or the second component 12, refer to one embodiment, such as... Figure 7 As shown, the extension 231 is continuously provided in the circumferential direction of the screw connector 23. At this time, the extension 231 can be integrally formed to facilitate the processing of the extension 231.

[0087] Of course, in other embodiments, the extension 231 is spaced apart in the circumferential direction of the screw connector 23 while meeting certain structural strength requirements, so as to reduce the material of the extension 231.

[0088] The extension 231 and the screw connector 23 are integrally formed, which can reduce the processing technology of the extension 231 and the screw connector 23, and increase the connection strength between the extension 231 and the screw connector 23.

[0089] To prevent the extension 231 from contacting the limiting head 22 at the periphery facing away from the screw connector 23, refer to one embodiment, such as... Figure 13 and Figure 14 As shown, the side of the limiting head 22 facing the screw 21 is quadrilateral, and the lengths of two adjacent sides of the quadrilateral are A1 and B1, respectively. The length of the receiving groove along the axial direction of the screw 21 is M, and the inner diameter of the receiving groove is N, and it satisfies: A1 2 +B1 2 <N 2 .

[0090] like Figures 1 to 5 As shown, this application also provides an elevator guide rail 30 bracket for mounting the guide rail 30 on a contact surface. The elevator guide rail 30 bracket includes a first component 11, a second component 12, and a fixing structure 20 as described in the above embodiments. The first component 11 is mounted on the contact surface, and the second component 12 is used to mount the guide rail 30.

[0091] There are multiple elevator guide rail 30 brackets in the elevator shaft. These brackets are arranged along the length of the guide rail 30 and fixed to the contact surface (e.g., wall) in the shaft. When installing the guide rail 30 in the shaft, the first component 11 is first fixed to the contact surface using expansion bolts 40 or similar means. The relative positions of the first component 11 and the second component 12 are then fixed using the fixing structure 20. Finally, the guide rail 30 is fixed to the second component 12.

[0092] In another embodiment, such as Figure 1 and Figure 3 As shown, the first component 11 includes a first substrate 112 and a first connecting plate 113. The first substrate 112 has a support surface that contacts the contact surface, and the first connecting plate 113 has a first mounting hole 111.

[0093] The second component 12 includes a second substrate 122 and a second connecting plate 123. The second substrate 122 has a mounting surface for mounting the guide rail 30. The first connecting plate 113 and the second connecting plate 123 are attached to each other. The second connecting plate 123 has a second mounting hole 121.

[0094] To reduce the processing complexity of the first component 11 and enhance its structural strength, the first substrate 112 and the first connecting plate 113 are integrally formed. The first component 11 can be bent to form the first substrate 112 and the first connecting plate 113. Of course, in other embodiments, the first substrate 112 and the first connecting plate 113 are fixed together by welding or bolts.

[0095] To reduce the processing complexity of the second component 12 and enhance its structural strength, the second substrate 122 and the second connecting plate 123 are integrally formed, i.e., the second component 12 itself is bent to form the second substrate 122 and the second connecting plate 123. Of course, in other embodiments, the second substrate 122 and the second connecting plate 123 are fixed together by welding or bolts.

[0096] The first substrate 112 and the first connecting plate 113 are arranged at an angle, and the second substrate 122 and the second connecting plate 123 are also arranged at an angle. To facilitate the connection between the first component 11 and the second component 12, in one embodiment, the first substrate 112 and the first connecting plate 113 are arranged at a right angle, and the second substrate 122 and the second connecting plate 123 are also arranged at a right angle. For example, both the first substrate 112 and the second substrate 122 are vertically arranged, and both the first connecting plate 113 and the second connecting plate 123 are horizontally arranged, with the first connecting plate 113 located above the second connecting plate 123.

[0097] In another embodiment, such as Figure 1 and Figure 3As shown, the elevator guide rail 30 bracket also includes:

[0098] At least two pressure plates 15 are located on opposite sides of the guide rail 30, pressing the guide rail 30 against the mounting surface of the connecting seat;

[0099] Multiple fastening bolts 16, each fastening bolt 16 passes through the corresponding pressure plate 15 and is fixedly connected to the connecting seat.

[0100] The pressure plate 15 is roughly block-shaped. The guide rail 30 is placed on the mounting surface of the second base plate 122. The pressure plate 15 is pressed onto the pressure edge of the guide rail 30, and then the pressure plate 15 is fixed to the second base plate 122 by the fastening bolts 16, so that the pressure plate 15 presses and fixes the guide rail 30, which can reduce the installation difficulty of the guide rail 30.

[0101] In this embodiment, there are two pressure plates 15, which are located on opposite sides of the guide rail 30. There are also two fastening bolts 16, each passing through a corresponding pressure plate 15. Of course, in other embodiments, there can be three or more pressure plates 15 and three or more fastening bolts 16. The number of pressure plates 15 and the number of fastening bolts 16 can be adjusted according to actual needs.

[0102] Both the second base plate 122 and the pressure plate 15 are provided with deformation grooves 223. The fastening bolt 16 includes a screw and a nut that is threadedly connected to the screw. The end of the screw facing away from the screw head passes through each deformation groove 223 in sequence and is then threadedly connected to the nut. The pressure plate 15 is pressed onto the guide rail 30 by the cooperation between the nut and the screw head.

[0103] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0104] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
