[0072] In an exemplary embodiment of the present invention, an example including a pair of swing arm assemblies 3 and a pair of rollers 4 is shown. However, those skilled in the art should understand that the number of swing arm assemblies 3 and rollers 4 should not be limited thereto.

[0073] Hereinafter, the structure of the present invention will be described in detail by taking a pair of swing arm assemblies 3 and a pair of rollers 4 as an example.

[0074] The combined guide shoe of the elevator of the present invention can be installed on the side of the car frame or the car, thereby saving the pit and top floor space.

[0075] With reference to Figure 6 , Figure 7 and Figure 9 , which respectively show three different forms of the base. Those skilled in the art can make various modifications and changes to the base based on the technical idea disclosed herein, and these modifications and changes all fall within the protection scope of the present invention.

[0076] The base 1 of the first embodiment of the present invention can be a welded part, the base 1' of the second embodiment of the present invention can be a casting or forging, and the base 1" of the third embodiment of the present invention can be a welded part, a casting or a forging.

[0077] With reference to Figure 6 , according to the first embodiment of the present invention, the base 1 is a plate-like member, on which there are provided an installation boss 11, a stepped portion 12, a limit block 13, a first installation hole 14, a second installation hole 15, an installation recess 16 and a third installation hole 17.

[0078] The mounting boss 11 can be provided on the upper part of the base 1 and includes a mounting hole 111 and a fixing hole 112. The limiting rod 21 of the limiting component 2, which will be specifically described below, can extend through the mounting hole 111 and pass through the mounting boss 11 to be mounted on the base 1.

[0079] The mounting hole 111 can extend along the axial direction of the limiting rod 21 and can be formed with an internal thread (not shown). The limiting rod 21 can be formed with an external thread (not shown) at a corresponding part (such as the middle part). Thus, the internal thread of the mounting hole 111 can cooperate with the external thread of the limiting rod 21, so that the limiting rod 21 can be mounted on the base 1.

[0080] The fixing hole 112 extends to the outer peripheral surface of the limiting rod 21 along a direction perpendicular to the axial direction of the limiting rod 21.

[0081] That is to say, the extending direction of the mounting hole 111 is perpendicular to the extending direction of the fixing hole 112, and the mounting hole 111 and the fixing hole 112 communicate with each other inside the mounting boss 11.

[0082] According to an exemplary embodiment of the present invention, it can further include a fixing bolt 6. The fixing bolt 6 is installed in the fixing hole 112 to abut against the outer peripheral surface of the limiting rod 21, so as to prevent the limiting rod 21 from rotating and moving.

[0083] The stepped portion 12 can be provided on the upper part of the base 1 and is located on both sides of the mounting boss 11. The stepped portion 12 can be used to limit the minimum limit position of the swing arm assembly 3, which will be specifically described below; the limiting block 13 can be provided on both sides of the base 1. The limiting block 13 can be used to limit the maximum limit position of the swing arm assembly 3.

[0084] Herein, the minimum limit position of the swing arm assembly 3 is the position of the minimum distance between the two swing arm assemblies 3, and the maximum limit position of the swing arm assembly 3 is the position of the maximum distance between the two swing arm assemblies 3.

[0085] The limiting block 13 can be in a block form.

[0086] The combined guide shoe of the elevator can be installed on the car frame or the car through the first mounting hole 14.

[0087] With reference to Figure 6 , the third mounting hole 17 is provided on the upper and lower sides of the mounting recess 16.

[0088] With reference to Figure 7 , it is a schematic diagram of the base 1' of the second embodiment. The main differences between the base 1' of the second embodiment and the base 1 of the first embodiment are: the form of the limiting block 13', the shape of the mounting recess 16', the position of the third mounting hole 17', and the mounting convex portion 3122'.

[0089] In the second embodiment of the present invention, the limiting block 13 can be in a columnar form.

[0090] However, those skilled in the art should understand that the structure of the limiting block is not limited thereto, and any other structure capable of achieving the same function can be used, and will not be elaborated herein.

[0091] With reference to Figure 9 , which is a schematic diagram of the base 1" of the third embodiment. The main difference between the base 1" of the third embodiment and the base 1 of the first embodiment lies in the arrangement of the first mounting holes 14".

[0092] In the third embodiment of the present invention, compared with the base 1 in the first embodiment, the base 1" is additionally provided with bending parts on the left and right sides, and the first mounting holes 14" are formed on the bending parts. The combined guide shoes of the elevator are installed on the car frame or the car through the first mounting holes 14".

[0093] The structure of the limiting component 2 will be specifically described below.

[0094] The limiting component 2 can be installed on the base 1 and includes a limiting rod 21.

[0095] Specifically, the limiting component 2 can be installed on the mounting boss 11 of the base 1.

[0096] According to an exemplary embodiment of the present invention, the two ends of the limiting rod 21 are provided with threads, and the limiting component 2 can further include locking nuts 22 arranged at the two ends of the limiting rod 21. The locking nuts 22 can be in threaded engagement with the threads at the two ends of the limiting rod 21. In particular, when the locking nut 22 is rotated, the locking nut 22 can generate a displacement in the axial direction of the limiting rod 21.

[0097] In an exemplary embodiment of the present invention, the limiting component 2 is in the form of a rod with threads at both ends, and the locking nuts 22 at the two ends are in threaded engagement with the corresponding threads, so as to play a limiting role. However, those skilled in the art should understand that the form of the limiting component 2 is not limited thereto, and any other structure capable of achieving the same function can be used, and will not be elaborated herein.

[0098] With reference to Figures 1 to 6 , the swing arm assembly 3 can be arranged in a left-right symmetric form, and the first end of the swing arm assembly 3 can be sleeved on the limiting rod 21 and can slide along the limiting rod 21, and the second end of the swing arm assembly 3 is rotatably installed on the base 1.

[0099] Furthermore, each swing arm assembly 3 can include a swing arm 31 and a sliding block 32.

[0100] The first end of the swing arm 31 may be provided with a first shaft 311, and the second end of the swing arm 31 may be mounted to the base 1 through a second shaft 312. The second end of the swing arm 31 is rotatable relative to the second shaft 312.

[0101] The slider 32 may be provided on the first end of the swing arm 31, and the slider 32 and the first shaft 311 are respectively located on opposite sides of the swing arm 31.

[0102] Specifically, the slider 32 is provided on the side of the swing arm 31 relatively close to the limit rod 21, and the first shaft 311 is provided on the side of the swing arm 31 relatively far from the limit rod 21.

[0103] According to an embodiment of the present invention, the slider 32 and the first shaft 311 may be integrally formed, and the integrally formed slider 32 and first shaft 311 may pass through the first end of the swing arm 31.

[0104] According to another embodiment of the present invention, the slider 32 and the first shaft 311 may be provided separately.

[0105] The slider 32 may be provided with a through hole 321, and the inner diameter of the through hole 321 is greater than the outer diameter of the limit rod 21, so that the slider 32 can slide along the limit rod 21 through the through hole 321.

[0106] The second shaft 312 may be installed in the second mounting hole 15, and the second end of the swing arm 31 may rotate about the axis of the second shaft 312.

[0107] A pair of rollers 4 are respectively installed at the first end of the corresponding swing arm assembly 3. As the first end of the swing arm assembly 3 slides along the limit rod 21, the distance between the pair of rollers 4 can be adjusted.

[0108] In the illustrated example, the roller 4 is installed on the first shaft 311 through a bearing 41.

[0109] The bearing 41 used for the roller 4 may be a single-row bearing, or a double-row or multi-row bearing. The structure of the bearing 41 may be a deep groove ball bearing, a cylindrical roller bearing, a sliding bearing, etc.

[0110] Further, according to the first embodiment of the present invention, with reference to Figure 5 , a first sleeve 3111 and a first snap ring 3112 may be provided on the first shaft 311. The first sleeve 3111 is located on the first side of the bearing 41, and the first snap ring 3112 is located on the second side of the bearing 41. The first snap ring 3112 may be configured to prevent the bearing 41 from detaching from the first shaft 311.

[0111] Here, the first side of the bearing 41 is the side of the bearing 41 relatively closer to the swing arm 31, which can also be referred to as the inner side of the bearing 41; the second side of the bearing 41 is the side of the bearing 41 relatively farther from the swing arm 31, which can also be referred to as the outer side of the bearing 41.

[0112] In other words, the first sleeve 3111 is located on the inner side of the bearing 41, positioned between the bearing 41 and the swing arm 31, and the first snap ring 3112 is located on the outer side of the bearing 41 to prevent the bearing 41 from disengaging from the first shaft 311.

[0113] Here, through the arrangement of the first snap ring 3112 and the first sleeve 3111, the position of the bearing 41 on the first shaft 311 can be restricted, and the reliability of the installation of the bearing 41 can be ensured.

[0114] In addition, through the arrangement of the first sleeve 3111, a rotational space for the roller 4 can be advantageously provided without interference with other components.

[0115] A second sleeve 3121, a third sleeve 3122, and a second snap ring 3123 can be provided on the second shaft 312. The third sleeve 3122 is located on the first side of the swing arm 31, and the second sleeve 3121 and the second snap ring 3123 are located on the second side of the swing arm 31. The second snap ring 3123 is configured to prevent the second sleeve 3121 from disengaging from the second shaft 312.

[0116] Here, the first side of the swing arm 31 is the side of the swing arm 31 relatively closer to the base 1, which can also be referred to as the inner side of the swing arm 31; the second side of the swing arm 31 is the side of the swing arm 31 relatively farther from the base 1, which can also be referred to as the outer side of the swing arm 31.

[0117] In other words, the third sleeve 3122 is located on the inner side of the swing arm 31, positioned between the swing arm 31 and the base 1; the second sleeve 3121 and the second snap ring 3123 are located on the outer side of the swing arm 31, and compared with the second sleeve 3121 and the second snap ring 3123, the second snap ring 3123 is located on the outermost side to prevent the second sleeve 3121 from disengaging from the second shaft 312.

[0118] In addition, through the arrangement of the third sleeve 3122, a rotational space for the swing arm 31 can be advantageously provided without interference with other components.

[0119] Moreover, through the arrangement of the third sleeve 3122, the swing arm 31 can be substantially oriented in the vertical direction, thereby making the movement (including rotation and sliding) of the swing arm assembly 3 smoother.

[0120] In addition, through the arrangement of the second sleeve 3121 and the third sleeve 3122, unwanted wobbling of the swing arm 31 can be avoided, which may cause misalignment between a pair of rollers 4, thus affecting the normal operation of the car.

[0121] In the second embodiment of the present invention, the mounting convex portion 3122' of the base 1' can be used to replace the third sleeve 3122 in the first embodiment, thereby reducing the number of components and lowering the cost.

[0122] The shoe lining 5 can be mounted to the base 1 and is located between a pair of rollers 4.

[0123] When the combined guide shoe of the elevator of the present invention is in use, the shoe lining 5 can contact the top surface of the guiding surface of the guide rail (not shown), while a pair of rollers 4 can contact the side surface of the guiding surface of the guide rail.

[0124] Since the distance between a pair of rollers 4 can be adjusted through the swing arm assembly 3, the rollers 4 can better fit the side surface of the guiding surface of the guide rail, thus making the car run more smoothly.

[0125] The combined guide shoe of the elevator of the present invention may further include a first shock absorber 7 and a second shock absorber 8. Among them, the first shock absorber 7 is mounted to the base 1 and is located between the shoe lining 5 and the base 1; the second shock absorber 8 can be sleeved on the limit rod 21 and is located between the sliding block 32 and the locking nut 22.

[0126] With reference to Figure 5 , in the first embodiment of the present invention, the first shock absorber 7 can be formed to be generally T-shaped and includes a protruding portion 71, and the protruding portion 71 can be mounted in the mounting recess 16 of the base 1. The first shock absorber 7 is arranged overlapping with the shoe lining 5.

[0127] When mounting the shoe lining 5 and the first shock absorber 7 on the base 1, first mount the first shock absorber 7 on the base 1, with the protruding portion 71 mounted in the mounting recess 16, and then press the shoe lining 5 against the first shock absorber 7. A fastening member 73 (such as a fastening bolt) can pass through the third mounting hole 17 of the base 1 and the through hole 72 of the first shock absorber 7 and be fastened to the shoe lining 5, thereby mounting the shoe lining 5 and the first shock absorber 7 to the base 1.

[0128] With reference to Figure 7 and Figure 8 , in the second embodiment of the present invention, the first shock absorber can be formed to be generally rectangular. Correspondingly, the mounting recess 16' of the base 1 in the second embodiment has a corresponding shape.

[0129] In addition, in the second embodiment of the present invention, the shoe lining 5' is additionally provided with a flange portion 51, and the position of the third mounting hole 17' is also different from that in the first embodiment. The third mounting hole 17' in the second embodiment is located on the left and right sides of the mounting recess 16'.

[0130] When mounting the shoe lining 5' and the first vibration damping member on the base 1', first mount the first vibration damping member on the base 1', wherein the first vibration damping member is integrally mounted into the mounting recess 16', then press the shoe lining 5' against the first vibration damping member, and finally press the pressing plate P against the flange portion 51 of the shoe lining 5'. The fastening member 73' (such as a rivet) can pass through the pressing plate P and be fixed to the third mounting hole 17' of the base 1', thereby mounting the shoe lining 5' and the first vibration damping member on the base 1'.

[0131] In an exemplary embodiment of the present invention, the first vibration damping member can be made of a rubber material. However, those skilled in the art should understand that the material and form of the first vibration damping member are not limited thereto, and any other material and form that can achieve the same function are acceptable, such as springs, disc springs, etc., which will not be elaborated here one by one.

[0132] In addition, in an exemplary embodiment of the present invention, the second vibration damping member 8 is formed in a block form and can be made of a rubber material. However, those skilled in the art should understand that the material and form of the second vibration damping member are not limited thereto, and any other material and form that can achieve the same function are acceptable, such as springs, disc springs, etc., which will not be elaborated here one by one.

[0133] By arranging the first vibration damping member and the second vibration damping member, the vibration during the operation of the car can be reduced, and the comfort of elevator riding can be improved.

[0134] The present invention provides a combined guide shoe having a shoe lining and a roller, which can ensure the smoothness of operation during the operation of the elevator. In addition, the guide shoe structure of the present invention is compact and can be conveniently installed on the side of the car frame or the car, which can not only save the pit and top floor space, but also reduce the friction and impact between the guide shoe and the guide rail, effectively reduce vibration, and improve the comfort of elevator riding.
