Description

Technical Field

[0001] This application relates to the field of host installation equipment technology, and in particular to host installation mechanisms and drive devices. Background Technology

[0002] In the field of drive equipment for escalators and moving walkways, vertical main units are often directly fixed to the truss using mounting bolts and rely on a drive chain for power transmission. During actual operation, the chain drive mechanism gradually loosens over time, leading to a decrease in drive chain tension. Therefore, after the main unit has been running continuously for a period of time, for example, approximately every six months, the mounting bolts need to be loosened, the main unit's position adjusted to tension the drive chain, and then the mounting bolts tightened again to secure the main unit.

[0003] However, because each adjustment requires repeatedly loosening and tightening the mounting bolts, the maintenance process is cumbersome and inconvenient. Furthermore, after multiple adjustments, the anti-loosening structure between the mounting bolts and the main unit is prone to failure, potentially causing the main unit to loosen. Additionally, the main unit may become eccentric during adjustment, affecting drive performance and even posing safety hazards. Utility Model Content

[0004] Therefore, it is necessary to provide a host installation mechanism and drive device to address the problems of inconvenient host position adjustment and potential loose installation.

The first limiting member and the second limiting member protrude from the mounting body in the thickness direction of the mounting body.

[0008] In one embodiment, the first limiting member has a first limiting surface on the side away from the second limiting member, and the second limiting member has a second limiting surface on the side away from the first limiting member.

[0011] The second end of the mounting body is recessed and provided with a relief groove, and the second limiting surface is flush with the bottom surface of the relief groove.

[0012] In one embodiment, the host mounting mechanism further includes a second limiting component connected to the same side of the mounting body in the width direction.

[0013] In one embodiment, the second limiting component includes a third limiting member and a fourth limiting member, the third limiting member and the fourth limiting member being spaced apart in the length direction of the mounting body, and the first limiting member and the second limiting member protruding from the mounting body in the thickness direction of the mounting body.

[0014] In one embodiment, the third limiting member has a third limiting surface on the side away from the mounting body, and the fourth limiting member has a fourth limiting surface on the side away from the mounting body, wherein the third limiting surface and the fourth limiting surface are coplanar.

[0015] In one embodiment, the mounting hole includes a limiting segment and a connecting segment, the limiting segment and the connecting segment are connected along the thickness direction of the mounting body to form a stepped hole, the cross-sectional area of ​​the limiting segment is larger than the cross-sectional area of ​​the connecting segment, and the limiting segment is located at the end of the connecting segment away from the first limiting component.

[0016] In one embodiment, the limiting segment has a rectangular cross-section and a chamfer.

[0022] The aforementioned host mounting mechanism and drive device, the drive device including the host mounting mechanism, are assembled together with the drive host, allowing the position of the drive host to be adjusted according to the position of the host mounting mechanism. Thus, adjusting the position of the drive host can be achieved by adjusting the position of the host mounting mechanism, suitable for miniaturized drive hosts, effectively improving maintenance convenience. Furthermore, the drive host does not need to be separated from the host mounting mechanism during adjustment, reducing the risk of loosening between the drive host and the host mounting mechanism and ensuring the stability of the drive host installation. Moreover, the first and second limiting components can act as limiters during adjustment, preventing the drive host from becoming eccentric and ensuring precise transmission between the drive host and the drive chain.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] See Figure 1 The diagram shows a front view of a drive device 1 according to an embodiment of this application. The drive device 1 provided in this embodiment includes a mounting base 20, a main unit mounting mechanism 10, and a drive main unit 30. This drive device 1 can be used in the fields of escalators and moving walkways, and achieves its driving function by transmitting force to the drive chain.

[0037] For example, the mounting base 20 can be a truss, or it can be welded to the truss of the escalator as a separate component. The main unit mounting mechanism 10 is fixed to the mounting base 20 by adjusting bolts 42, and the drive unit 30 is connected to the main unit mounting mechanism 10 through mounting holes 110 and mounting bolts 41. The limiting and adjusting functions of the main unit mounting mechanism 10 improve the convenience of adjusting the drive chain tension, while ensuring the stability and accuracy of the drive unit 30 installation, avoiding problems such as eccentricity during adjustment, and improving the reliability and maintenance efficiency of the drive equipment 1. This is suitable for scenarios requiring a vertical drive unit 30, such as escalators and moving walkways.

[0038] See Figures 1 to 3 As shown, in some embodiments, the host mounting mechanism 10 includes a mounting body 100 and a first limiting component. The host mounting mechanism 10 is used to support the drive host 30, which helps to increase the adjustment space of the drive host 30 and prevent problems such as loosening during the adjustment of the position of the drive host 30.

[0039] The mounting body 100, as the main component supporting the drive host 30, can be made of metal to ensure sufficient strength. For example, the mounting body 100 can be a metal plate structure such as a steel plate. The mounting body 100 is provided with mounting holes 110 for mounting bolts 41 for fixing the drive host 30.

[0040] The first limiting assembly includes a first limiting member 210 and a second limiting member 220, which are fixed to the mounting body 100 by welding or bolts. The first limiting member 210 and the second limiting member 220 are respectively disposed on both sides of the mounting hole 110 along the length of the mounting body 100, and protrude beyond the thickness of the mounting body 100. It should be noted that the length of the mounting body 100 is... Figures 1 to 3 The horizontal direction from the viewing angle, and the thickness direction of the mounting body 100 are respectively... Figure 1 and Figure 3 The vertical direction from the viewing angle is the width direction of the mounting body 100. Figure 2 The vertical direction from the perspective of the viewpoint; all descriptions of directions in this article can be understood by referring to the explanations here.

[0041] For example, refer to Figure 1 As shown, when the host mounting mechanism 10 is used to support the drive host 30, the drive host 30 is connected to the mounting body 100 by mounting bolts 41. The mounting base 20 is provided with a front push rod bolt 43 and a rear push rod bolt 44. The front push rod bolt 43 abuts against the first limiting member 210, and the rear push rod bolt 44 abuts against the second limiting member 220, thereby limiting the front and rear movement of the mounting body 100 connected to the first limiting member 210 and the second limiting member 220.

[0042] With the above structural design, when it is necessary to adjust the installation position of the drive unit 30, the front push rod bolt 43 can be adjusted to push the mounting body 100 towards the rear push rod bolt 44, while the rear push rod bolt 44 is loosened to release the restriction on the mounting body 100. This allows for adjustment of the position of the drive unit 30 connected to the mounting body 100, making maintenance more convenient. Furthermore, since the front push rod bolt 43 and the rear push rod bolt 44 act on the first limiting member 210 and the second limiting member 220 respectively, they will not come into contact with the drive unit 30 during the adjustment process, thus preventing damage to the surface of the drive unit 30.

[0043] Therefore, in this embodiment, the host mounting mechanism 10 is assembled with the drive host 30 via mounting bolts 41, allowing the position of the drive host 30 to be adjusted according to the position of the host mounting mechanism 10. This means that adjusting the position of the drive host 30 can be achieved simply by adjusting the position of the host mounting mechanism 10, making it suitable for miniaturized drive hosts 30 and effectively improving maintenance convenience. Furthermore, the drive host 30 does not need to be separated from the host mounting mechanism 10 during adjustment, reducing the risk of loosening of the mounting bolts 41 between the drive host 30 and the host mounting mechanism 10, and ensuring the stability of the drive host 30's installation. Moreover, the first limiting member 210 and the second limiting member 220 can act as limiting elements during adjustment, preventing the drive host 30 from becoming eccentric and ensuring precise transmission between the drive host 30 and the drive chain.

[0044] Compared to directly fixing the drive unit 30 to the mounting base 20, in this embodiment, the drive unit 30 is supported by the host mounting mechanism 10. Therefore, the torque of the mounting bolts 41 between the drive unit 30 and the host mounting mechanism 10 only needs to be confirmed during installation and does not require further adjustment. Even if torque measurement is necessary, the increased operating space under the drive unit 30 by the host mounting mechanism 10 makes operation more convenient and facilitates torque measurement of the mounting bolts 41 that fix the drive unit 30, thus determining the tension level.

[0045] See Figure 1 and Figure 2 As shown, the first limiting member 210 has a first limiting surface 211 on the side away from the second limiting member 220, and the second limiting member 220 has a second limiting surface 221 on the side away from the first limiting member 210. Both the first limiting surface 211 and the second limiting surface 221 are perpendicular to the length direction of the mounting body 100. Specifically, both the first limiting member 210 and the second limiting member 220 are elongated structures, and the first limiting surface 211 and the second limiting surface 221 are planar. When the drive host 30 is fixed, the front push rod bolt 43 can be tightly fitted with the first limiting surface 211, and the rear push rod bolt 44 can be tightly fitted with the second limiting surface 221, thereby forming a positioning reference in the length direction of the mounting body 100. This ensures that the installation direction of the drive host 30 is strictly aligned, avoids loosening problems caused by uneven force on the drive chain due to the tilt of the drive host 30, and reduces the risk of deformation of the mounting body 100.

[0046] Further, see Figure 2As shown, the mounting body 100 has a first end 120 and a second end 130 opposite each other in the length direction. The second end 130 of the mounting body 100 is recessed inward and provided with a relief groove 131. A first limiting member 210 is provided at the first end 120 of the mounting body 100, and the first limiting surface 211 of the first limiting member 210 is flush with the end face of the first end 120 of the mounting body 100. Therefore, by setting the first limiting surface 211 to be flush with the end face of the mounting body 100, the first limiting surface 211 can be directly used as a positioning reference when adjusting the installation position of the mounting body 100, reducing positioning errors.

[0047] Furthermore, the second limiting member 220 is located at the second end 130 of the mounting body 100, and the second limiting surface 221 is flush with the bottom surface of the relief groove 131. The relief groove 131 is designed to avoid interference between the mounting body 100 and the rear top rod bolt 44 without affecting the limiting function, thereby improving the utilization of installation space and facilitating installation positioning.

[0048] Another consideration is that during the adjustment of the mounting body 100's position, the parallelism of the sides of the mounting body 100 may be difficult to guarantee, potentially leading to eccentricity issues after the drive host 30 moves backward, causing abnormal noise and vibration. Therefore, in some embodiments, the host mounting mechanism 10 can be further optimized.

[0049] See Figure 2 and Figure 3 As shown, the host mounting mechanism 10 also includes a second limiting component, which is connected to the same side of the mounting body 100 in the width direction. Specifically, the second limiting component includes a third limiting member 310 and a fourth limiting member 320, which are spaced apart in the length direction of the mounting body 100. The first limiting member 210 and the second limiting member 220 protrude from the mounting body 100 in the thickness direction. The third limiting member 310 and the fourth limiting member 320 can form a double limiting on the width direction of the mounting body 100, so that the guidance and fastening of the drive host 30 both act on the side of the mounting body 100, which can easily ensure the guiding accuracy and has a large adjustment space, thus restricting the movement of the drive host 30 in the width direction. At the same time, the second limiting component cooperates with the first limiting component to limit the movement, which can effectively prevent the drive host 30 from eccentricity or shaking during operation, enhance vibration resistance, reduce the risk of loosening of the mounting bolts 41, and improve the reliability of anti-loosening.

[0050] Furthermore, the third limiting member 310 has a third limiting surface 311 on the side away from the mounting body 100, and the fourth limiting member 320 has a fourth limiting surface 321 on the side away from the mounting body 100. The third limiting surface 311 and the fourth limiting surface 321 are coplanar. Coplanarity means that the third limiting surface 311 and the fourth limiting surface 321 are on the same plane. Therefore, the mounting body 100 receives a more uniform supporting force in the width direction, ensuring consistency in guidance and limiting, and preventing tilting of the mounting body 100 and the drive host 30 due to positional deviations of the third limiting surface 311 and the fourth limiting surface 321, further improving guidance and installation accuracy.

[0051] To further improve the installation stability between the mounting body 100 and the drive host 30, in some embodiments, the mounting hole 110 can be optimized.

[0052] See Figure 2 and Figure 3 As shown, the mounting hole 110 includes a limiting section 111 and a connecting section 112. The limiting section 111 and the connecting section 112 are connected along the thickness direction of the mounting body 100, making the mounting hole 110 a stepped hole. The limiting section 111 has a rectangular cross-section and a chamfer. Furthermore, the cross-sectional area of ​​the limiting section 111 is larger than the cross-sectional area of ​​the connecting section 112, and the limiting section 111 is located at the end of the connecting section 112 furthest from the first limiting component. The cross-sectional areas of the limiting section 111 and the connecting section 112 refer to the cross-sectional areas of the limiting section 111 and the connecting section 112 at... Figure 3 The projected area on the horizontal plane from the viewing angle. Therefore, when fixing the mounting body 100 and the drive unit 30 through the mounting hole 110 and mounting bolt 41, the mounting bolt 41 can be threaded backwards onto the mounting body 100 and connected with a nut, allowing the bolt head of the mounting bolt 41 to sink into the limiting section 111 of the mounting hole 110. This utilizes the inner wall of the limiting section 111 to prevent the mounting bolt 41 from rotating, avoiding loosening of the mounting bolt 41 and thus preventing the drive unit 30 from becoming loose from the mounting body 100, thereby improving connection reliability.

[0053] Optionally, when connecting to the mounting hole 110 via the mounting bolt 41 and nut, further anti-loosening reinforcement can be achieved by setting anti-loosening washers or applying thread-locking adhesive.

[0054] In addition, see Figure 1 and Figure 2As shown, the mounting body 100 also has four adjustment holes 140, which penetrate the mounting body 100 and whose length direction is parallel to that of the mounting body 100. For example, the adjustment hole 140 is an elongated hole for inserting an adjustment bolt 42, thereby fixing the mounting body 100 to the mounting base 20 through the cooperation of the adjustment bolt 42 and the adjustment hole 140. Since the adjustment hole 140 extends along the length direction of the mounting body 100 and the adjustment bolt 42 passes through it, the adjustment bolt 42 can move along the length direction of the adjustment hole 140. Therefore, when adjusting the mounting position of the mounting body 100, the tension of the drive chain can be adjusted by pushing the mounting body 100 along the adjustment hole 140 using the front push rod bolt 43. Simultaneously, the adjustment hole 140 can also restrict the movement direction of the mounting body 100, further improving the installation accuracy of the mounting body 100 and the drive host 30.

[0055] It is understood that in other alternative embodiments, the number of adjustment holes 140 is not limited to four. For example, the number of adjustment holes 140 can also be one, two, three, five, six, etc.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, 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 all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
