Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to a weld-free adjustable support frame and elevator guide rail installation structure. Background Technology

[0002] In the elevator industry, a support frame is a component installed between the shaft wall and the elevator guide rails. The support frame has pressure brackets to hold the elevator guide rails in place. In existing technology, such as... Figure 1 and Figure 2 As shown, the support frame includes a support leg (100) and a connecting plate (200). The support leg (100) is fixedly installed on the shaft wall, while the connecting plate (200) has an elongated hole (210). The connecting plate (200) is fixed to the support leg (100) through the elongated hole (210) using a bolt assembly (300). The pressure plate ( Figure 1 and Figure 2 (Not shown in the figure) The elevator guide rail (400) is set on the connecting plate; when the elevator guide rail (400) is subjected to X and Y forces, as shown by Px and Py in the figure, the fastening force is provided by the friction of the mating surface between the connecting plate (200) and the bracket (100). Because the friction is small and can be unstable due to vibration, the bracket and the connecting plate are often welded together to reinforce them due to insufficient force in order to meet the requirements of the support frame. The support frame requires welding, which makes the installation operation more complicated and less efficient. Furthermore, when the elevator guide rail needs to be adjusted later, the support frame must be destroyed, which greatly hinders the adjustment of the elevator guide rail. Summary of the Invention

[0003] In view of this, the present invention provides a weld-free adjustable support frame and elevator guide rail installation structure, the purpose of which is to optimize the structure of the support frame so that the support frame can still ensure the stability of the load-bearing structure without the need for welding reinforcement.

[0004] The technical solution of this invention is implemented as follows:

[0005] Firstly, a weld-free adjustable support frame is provided, comprising:

[0006] The bracket includes a first mounting plate mounted on the shaft wall, at least two second mounting plates vertically distributed on the first mounting plate, a third mounting plate connected to the end of each second mounting plate away from the first mounting plate, the third mounting plate being parallel to the first mounting plate, and having at least two adjustment holes; and

[0007] A connecting plate, the number of which corresponds to the third mounting plate, is provided on the side of the third mounting plate away from the second mounting plate. A connecting post is provided on one side of the connecting plate and passes through the adjustment hole. At least one first limiting ring and at least one second limiting ring are threadedly connected to the connecting post.

[0035] refer to Figure 3-8 This paper demonstrates a weld-free adjustable support frame and elevator guide rail installation structure.

[0036] The weldless adjustable support includes a support leg 1 and a connecting plate 2. The support leg 1 includes a first mounting plate 11 installed on the shaft wall. At least two second mounting plates 12 are arranged vertically on the first mounting plate 11. A third mounting plate 13 is connected to the end of the second mounting plate 12 away from the first mounting plate 11. The third mounting plate 13 is arranged parallel to the first mounting plate 11 and has at least two adjustment holes 131. The number of connecting plates 2 corresponds to the number of third mounting plates 13. The connecting plates 2 are located on the side of the third mounting plate 13 away from the second mounting plates 12. A connecting post 21 is provided on one side of the connecting plate 2 and passes through the adjustment hole 131. At least one first limiting ring 22 and at least one second limiting ring 23 are threadedly connected to the connecting post 21. The first limiting ring 22 and the second limiting ring 23 are located on both sides of the third mounting plate 13 to clamp the third mounting plate 13.

[0037] The elevator guide rail installation structure includes a weld-free adjustable support frame. The first mounting plate 11 is fixed to the shaft wall by expansion bolts. A pressure bar 500 is detachably connected to the connecting plate 2, and the elevator guide rail 400 is pressed onto the connecting plate 2 by the pressure bar 500.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, when the elevator guide rail 400 is subjected to a force Px in the X direction and a force Py in the Y direction, the elevator guide rail 400 transmits the force to the connecting plate 2, and the connecting column 21 on the connecting plate 2 pushes against the third mounting plate 13, and then the third mounting plate 13 distributes the force to the bracket 1; in this way, the weldless adjustable support does not rely on friction to resist the force on the elevator guide rail 400. Through the design of the bracket 1, the connecting plate 2 and the connection structure between them, the structural strength of the weldless adjustable support itself can bear the force on the elevator guide rail 400; no welding is required between the bracket 1 and the connecting plate 2, reducing the installation complexity and improving the installation efficiency, and the position of the connecting plate 2 can be adjusted by the first limiting ring 22 and the second limiting ring 23, thereby facilitating the adjustment of the elevator guide rail 400. In addition, the elevator guide rail installation structure requires no welding, has low installation complexity and high installation efficiency; when it is necessary to adjust the elevator guide rail 400, there is no need to damage the support frame, the adjustment speed is fast and the adjustment operation is simple.

[0039] refer to Figure 2When it is necessary to adjust the position of the connecting plate 2, the first limiting ring 22 and the second limiting ring 23 can be rotated to adjust their positions on the connecting post 21, thereby adjusting the distance between the connecting plate 2 and the third mounting plate 13. It should be noted that the first limiting ring 22 and the second limiting ring 23 can be nuts, which are technologically mature and readily available. More than one of each of the first limiting ring 22 and the second limiting ring 23 can be provided to prevent loosening caused by vibration.

[0040] In some embodiments, reference Figure 7 and Figure 8 The second mounting plate 12 is perpendicular to the first mounting plate 11, and the second mounting plate 12 is horizontally positioned when not under stress. The forces in the X and Y directions, namely Px and Py, are both horizontal forces. The horizontal positioning of the second mounting plate 12 effectively resists Px and Py, thereby improving its bending resistance and enhancing the structural stability of the bracket 1.

[0041] Based on this, refer to Figure 4-6 At least two adjustment holes 131 are symmetrically distributed on both sides of the second mounting plate 12, and all adjustment holes 131 are at the same horizontal height as the second mounting plate 12. In this embodiment, only two adjustment holes 131 are provided; in other embodiments, four, six, etc., can be provided. It is sufficient that the adjustment holes 131 on both sides are symmetrically distributed. Thus, when either side of the connecting plate 2 is subjected to a force in the Y direction, the second mounting plate 12 can be stably supported. Since the adjustment holes 131 are at the same horizontal height as the second mounting plate 12, the force transmitted by the third mounting plate 13 can only be located at the horizontal height of the second mounting plate 12, preventing the force from bending the second mounting plate 12 in the thickness direction, thus fully utilizing the structural strength of the second mounting plate 12.

[0042] Additionally, refer to Figure 4-6The number and position of the connecting posts 21 on the connecting plate 2 correspond to the adjustment holes 131 on the third mounting plate 13. The connecting plate 2 is provided with connecting holes 25 for installing the pressure bracket 500, and the connecting holes 25 and the connecting posts 21 are at the same horizontal height. Thus, the pressure bracket 500 can be installed on the connecting holes 25 of the connecting plate 2 by bolts (not marked in the figure). When the elevator guide rail 400 is under force, the elevator guide rail 400 first transmits the force to the pressure bracket 500, and then transmits the force to the connecting plate 2 through the pressure bracket 500. The fact that the connecting holes 25 and the connecting posts 21 are at the same horizontal height is beneficial because the direction of force transmission is at the horizontal height of the second mounting plate 12, avoiding bending of the second mounting plate 12 from the thickness direction of the second mounting plate 12, so that the structural strength of the second mounting plate 12 is fully utilized.

[0043] In some embodiments, reference Figure 7 The adjustment hole 131 is a strip-shaped hole arranged horizontally along its length.

[0044] Specifically, when the first limiting ring 22 and the second limiting ring 23 are not clamping the third mounting plate 13, the connecting column 21 can move laterally in the adjusting hole 131, thereby adjusting the lateral position of the connecting plate 2 relative to the third mounting plate 13, so as to facilitate the vertical position correspondence between the elevator guide rails 400.

[0045] In some embodiments, reference Figure 3 and Figure 7 The first mounting plate 11 is provided with a plurality of fixing holes 111 along its thickness direction. The expansion bolts pass through the fixing holes 111 and are driven into the well wall, thereby fixing the first mounting plate 11. In order to facilitate fine adjustment of its position when fixing the first mounting plate 11 and to facilitate the horizontal setting of the second mounting plate 12, in this embodiment, the fixing holes 111 are strip-shaped holes, at least some of the fixing holes 111 are set horizontally along their length direction, and at least some of the fixing holes 111 are set vertically along their length direction.

[0046] In some embodiments, reference Figure 4 A self-locking washer 24 is provided between the first limiting ring 22 and the third mounting plate 13, and / or between the second limiting ring 23 and the third mounting plate 13. Thus, the self-locking washer 24 prevents the first limiting ring 22 or the second limiting ring 23 from loosening, ensuring that the first limiting ring 22 and the second limiting ring 23 can clamp the third mounting plate 13.

[0047] In addition, for ease of manufacturing, a through hole can be opened on the third mounting plate 13, a bolt is inserted into the through hole, and the bolt is welded to the third mounting plate 13 for fixation. The stud of the bolt forms the connecting column 21. The weldless adjustable support structure of the present invention is simple, but can exert excellent structural stability, improve the installation efficiency of the elevator guide rail 400 and facilitate the subsequent maintenance and adjustment of the elevator guide rail 400.

[0048] In addition, when the elevator guide rail is subjected to a vertical force (not shown in the figure), the weldless adjustable support still does not rely on friction to resist the force on the elevator guide rail 400.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
