[0002] In the field of elevators, a support frame is a component arranged between the hoistway wall and the elevator guide rail, and a pressure code is arranged on the support frame to press the elevator guide rail onto the support frame; in the prior art, such as Figure 1 and Figure 2 As shown, the support frame includes a support leg (100) and a connecting plate (200), wherein the support leg (100) is fixedly mounted on the well wall, and the connecting plate (200) is provided with an oblong hole (210), and the connecting plate (200) is fixed to the support leg (100) through the oblong hole (210) by using a bolt assembly (300), and the pressing plate ( Figure 1 and Figure 2 (not shown) the elevator guide rail (400) is arranged on the connecting plate; when the elevator guide rail (400) is subjected to forces in the X and Y directions, such as Px and Py in the figure, the friction force of the joint surface between the connecting plate (200) and the frame foot (100) provides the fastening force. Since the friction force is small and the friction force is unstable due to vibration factors, welding reinforcement is often performed between the frame foot and the connecting plate due to insufficient force to meet the use requirements of the support frame; wherein, the support frame requires welding operation, which makes the installation operation more complicated and the installation efficiency low, and 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.

[0035] refer to Figure 3-8 , showing a welding-free adjustable support frame and elevator guide rail installation structure;

[0036] Among them, the weld-free adjustable support frame includes a frame foot 1 and a connecting plate 2, the frame foot 1 includes a first mounting plate 11 installed on the shaft wall, the first mounting plate 11 is provided with at least two second mounting plates 12 distributed vertically, the second mounting plate 12 is connected to a third mounting plate 13 at one end away from the first mounting plate 11, the third mounting plate 13 is arranged parallel to the first mounting plate 11, and at least two adjustment holes 131 are provided on the third mounting plate 13; the number of the connecting plates 2 corresponds to the third mounting plate 13, the connecting plate 2 is arranged on the side of the third mounting plate 13 away from the second mounting plate 12, one side of the connecting plate 2 is provided with a connecting column 21 penetrated by the adjusting hole 131, at least one first limiting ring 22 and at least one second limiting ring 23 are threadedly connected to the connecting column 21, the first limiting ring 22 and the second limiting ring 23 are respectively located on both sides of the third mounting plate 13 to clamp the third mounting plate 13.

[0037] Among them, the elevator guide rail installation structure includes the non-welded adjustable support frame, the first mounting plate 11 is fixed to the shaft wall by expansion bolts, the pressure code 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 code 500.

[0038] Specifically, if Figure 3 and Figure 4 As shown, when the elevator guide rail 400 is subjected to the force Px in the X direction and the 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 will push the third mounting plate 13, and then the third mounting plate 13 disperses the force to the frame foot 1; in this way, the non-welded adjustable support frame does not rely on friction to resist the force exerted on the elevator guide rail 400, and through the design of the frame foot 1, the connecting plate 2 and the connection structure therebetween, the structural strength of the non-welded adjustable support frame itself is used to withstand the force exerted on the elevator guide rail 400; no welding is required between the frame foot 1 and the connecting plate 2, which reduces the installation complexity and improves the installation efficiency, and the position of the connecting plate 2 can be adjusted by the first limit ring 22 and the second limit ring 23, thereby facilitating the adjustment of the elevator guide rail 400. In addition, the elevator guide rail installation structure does not require welding, has low installation complexity and high installation efficiency; when the elevator guide rail 400 needs to be adjusted, there is no need to destroy the support frame, the adjustment speed is fast and the adjustment operation is simple.

[0039] refer to Figure 2When the position of the connecting plate 2 needs to be adjusted, the first limiting ring 22 and the second limiting ring 23 can be rotated to adjust the positions of the first limiting ring 22 and the second limiting ring 23 on the connecting column 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, and the component technology is mature and easy to obtain. More than one of the first limiting ring 22 and the second limiting ring 23 can be provided to achieve the effect of preventing loosening caused by vibration.

[0040] In some embodiments, reference Figure 7 and Figure 8 The second mounting plate 12 is vertically arranged with respect to the first mounting plate 11, and the second mounting plate 12 is horizontally arranged when not subjected to force. The forces in the X direction and the Y direction, namely Px and Py, are both horizontal forces. The second mounting plate 12 is horizontally arranged, which can effectively resist Px and Py, thereby improving the bending resistance of the second mounting plate 12 and strengthening the structural stability of the stand leg 1.

[0041] On this basis, reference Figure 4-6 , the at least two adjustment holes 131 are symmetrically distributed on both sides of the second mounting plate 12, and all the adjustment holes 131 are at the same level as the second mounting plate 12. In this embodiment, only two adjustment holes 131 are provided, and in other embodiments, four, six, etc., may be provided, and it is sufficient that the adjustment holes 131 on both sides are symmetrically distributed, so that when any side of the two sides of the connecting plate 2 is subjected to a force in the Y direction, the second mounting plate 12 can be stably supported; the adjustment holes 131 are at the same level as the second mounting plate 12, so that the force transmitted by the third mounting plate 13 can only be at the level of the second mounting plate 12, avoiding the force from bending the second mounting plate 12 in the thickness direction of the second mounting plate 12, so that the structural strength of the second mounting plate 12 is fully utilized.

[0042] In addition, refer to Figure 4-6, the number and position of the connecting columns 21 on the connecting plate 2 correspond to the adjustment holes 131 on the third mounting plate 13, and the connecting plate 2 is provided with a connecting hole 25 for installing the pressure code 500, and the connecting hole 25 and the connecting column 21 are located at the same level. In this way, the pressure code 500 can be installed on the connecting hole 25 of the connecting plate 2 by bolts (not marked in the figure); when the elevator guide rail 400 is subjected to force, the elevator guide rail 400 first transmits the force to the pressure code 500, and then transmits the force to the connecting plate 2 through the pressure code 500, and the connecting hole 25 and the connecting column 21 are located at the same level, which is conducive to the force transmission direction being located at the level of the second mounting plate 12, avoiding the force from bending the second mounting plate 12 in the thickness direction of the second mounting plate 12, so that the structural strength of the second mounting plate 12 is fully exerted.

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

[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 adjustment 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 opened along the thickness direction thereof, and the expansion bolts pass through the fixing holes 111 and are driven into the shaft wall, thereby fixing the first mounting plate 11; in order to facilitate fine-tuning of the position of the first mounting plate 11 when fixing it and to facilitate the horizontal setting of the second mounting plate 12, in this embodiment, the fixing holes 111 are strip holes, and at least part of the fixing holes 111 are arranged horizontally in the length direction, and at least part of the fixing holes 111 are arranged vertically in the 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, or / and, a self-locking washer 24 is provided between the second limiting ring 23 and the third mounting plate 13. In this way, the self-locking washer 24 is used to prevent 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, to facilitate manufacturing, a through hole can be opened on the third mounting plate 13, a bolt can be inserted into the through hole, and the bolt is welded and fixed to the third mounting plate 13, and the stud of the bolt forms the connecting column 21; the weld-free adjustable bracket 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 non-welded adjustable support frame still does not rely on friction to resist the force exerted 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 in the protection scope of the present invention.
