Description

Technical Field

[0001] This utility model relates to the field of elevator accessories technology, specifically to a centrally pressed elevator door mounting plate. Background Technology

[0002] Vertical elevators are increasingly used in people's production and daily life as a common transportation device in multi-story buildings. However, since the operation of vertical elevators involves rapid changes in height, safety issues can easily lead to serious consequences. Therefore, improving the operating performance of elevators has been a continuous research direction in the industry.

[0003] As the main component for mounting elevator doors on and moving them along the track, the elevator door mounting plate typically has a structure similar to the elevator door mounting plate assembly disclosed in patent CN202808134U. This assembly includes a mounting plate, upper rollers and a roller assembly for engaging with the track, and a flange at the lower end of the mounting plate for connecting to the elevator door panel. The flange is fixedly connected to the elevator door panel by multiple welded nuts. Therefore, existing elevator door mounting plates are all connected to the elevator door panel via the bottom flange. Furthermore, to ensure the elevator door panel is vertical after installation, the bottom flange of the elevator door mounting plate is vertically bent to maintain a horizontal bottom surface. When connecting the elevator door panel to the elevator door mounting plate, the top surface of the elevator door panel contacts the bottom surface of the flange, and then the elevator door panel is fixedly connected to the flange using bolts or other connectors. While the aforementioned structure meets the installation requirements of the elevator door panel, the bottom of the entire folded edge contacts the top surface of the elevator door panel, resulting in a large contact area. Furthermore, due to limitations in processing technology and the material's inherent properties, ensuring the entire bottom surface of the folded edge is on the same plane without any uneven deformation during processing is difficult. This leads to issues with achieving the required bending angle and flatness, necessitating multiple reshaping steps and reducing processing efficiency. Additionally, during subsequent on-site installation of the elevator door mounting plate, the large contact area increases the probability of installation being affected, posing a significant risk to installation accuracy. This increases the likelihood and time required for adjustments, impacting on-site installation efficiency. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention aims to provide a centrally pressed elevator door panel. This panel features a concave clearance notch formed by pressing the center of the bottom folded edge, preventing the center of the folded edge from contacting the top surface of the elevator door panel. This reduces the area requiring precision machining on the folded edge, thus lowering processing difficulty. Furthermore, the folded edge can be corrected during pressing, improving processing efficiency. The concave clearance notch also allows for more space for adjustment and installation, accommodating deformation of the elevator door's upper end cap, resulting in better adaptability. Additionally, the pressed side acts as a reinforcing rib, enhancing overall structural strength, preventing bending deformation under heavy loads, and extending service life.

[0005] The specific technical solution is as follows: A centrally pressed elevator door mounting plate is characterized by comprising: a mounting plate body, the bottom of the mounting plate body being bent to one side to form a folded edge, the bottom surface of the folded edge being a mounting surface, the middle part of the folded edge being pressed inward to form a concave clearance notch in the middle of the mounting surface, and connecting holes being provided on the folded edge and on both sides of the clearance notch.

[0006] The aforementioned type of elevator door mounting plate with a centrally pressed profile includes a clearance hole on the mounting plate body, and each connecting hole corresponds to a clearance hole. In addition, in the horizontal direction, each clearance hole is located to the side of the corresponding connecting hole.

[0007] In the aforementioned type of elevator door mounting plate with a centrally pressed profile, several adjusting shims are provided between the mounting surface of the folded edge and the top end face of the elevator door plate.

[0008] In the aforementioned type of elevator door mounting plate with a centrally pressed profile, two upper rollers are rotatably mounted on one side of the upper part of the mounting plate body, and the two upper rollers are respectively located at both ends of the mounting plate body.

[0009] In the aforementioned type of elevator door mounting plate with a centrally pressed profile, a roller assembly is rotatably mounted on one side of the lower part of the mounting plate body. The roller assembly includes several rollers arranged in a horizontal direction, and the rollers are rolled on a track.

[0010] The aforementioned type of elevator door mounting plate with a centrally pressed profile further includes an anti-detachment component, which is disposed on one side of the mounting plate body. The anti-detachment component includes an upper anti-detachment hook and a lower anti-detachment hook, with the upper anti-detachment hook bent downwards and the lower anti-detachment hook bent upwards. The upper and lower anti-detachment hooks are respectively disposed above and below the track on the upper sill base plate.

[0011] In the aforementioned type of elevator door mounting plate with a central pressing section, the upper anti-detachment hook and the mounting plate body are an integral structure, and the upper anti-detachment hook is formed by stamping and bending the mounting plate body.

[0012] In the aforementioned type of elevator door mounting plate with a central pressing section, the lower anti-detachment hook is detachably installed on the mounting plate body. The lower anti-detachment hook includes an anti-detachment hook body and a mounting component. A through hole and a fixing hole located next to the through hole are provided on the mounting plate body. One end of the anti-detachment hook body passes through the through hole and extends to the same side as the upper anti-detachment hook. The other end of the anti-detachment hook body is located on the side opposite to the upper anti-detachment hook and is connected to the fixing hole through the mounting component.

[0013] The positive effects of the above technical solution are: The aforementioned centrally pressed elevator door panel, by pressing the center of the folded edge at the bottom of the panel body, forms a concave clearance notch in the center of the mounting surface of the folded edge. This ensures that when the folded edge is connected to the elevator door panel, the center of the folded edge no longer contacts the top end face of the elevator door panel, reducing the area of ​​the mounting surface. This reduces the area of ​​the mounting surface on the folded edge that requires processing precision, lowers the processing difficulty, and facilitates manufacturing. At the same time, the folded edge can be corrected during the pressing process, improving processing efficiency. Furthermore, the deformed structure after pressing can be used as a reinforcing structure for the elevator door panel, resulting in higher overall structural strength and effectively preventing bending deformation when the elevator door panel is too heavy. In addition, the concave clearance notch can reserve more space for adjustment and installation, adapting to the deformation of the elevator door end cap, thus improving structural adaptability.

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0017] Figure 1This is a structural diagram of a centrally pressed elevator door mounting plate according to this utility model. Figure 1 As shown, the elevator door mounting plate with a central pressing structure provided in this embodiment includes: a mounting plate body 1, which enables the elevator door panel 7 to be installed on the track.

[0018] Specifically, the bottom of the mounting plate body 1 is bent to one side to form a folded edge 11. The bending angle of the folded edge 11 is 90°, which achieves a vertical bend at the bottom of the mounting plate body. This ensures that when the mounting plate body 1 is hung on the guide rail in a vertical position, this side remains horizontal, thus ensuring that the elevator door panel 7 connected to it remains vertical and maintains the smooth operation of the elevator door. At this time, the bottom surface of the folded edge 11 is the mounting surface 111, which contacts the top end face of the elevator door panel 7, serving as a reference surface for the installation of the elevator door panel 7 and ensuring installation accuracy. In addition, the middle part of the folded edge 11 is pressed inward to form a concave clearance notch 112 in the middle of the mounting surface 111. This ensures that when the folded edge 11 is connected to the elevator door panel 7, the middle part of the folded edge 11 no longer contacts the top end face of the elevator door panel 7. This reduces the area that needs to be processed to ensure accuracy when processing the folded edge 11, effectively reducing the processing difficulty while ensuring installation accuracy and facilitating manufacturing. Simultaneously, the folded edge 11 is corrected during the pressing process, eliminating the need for additional shaping and improving processing efficiency. Furthermore, the formation of the concave clearance notch 112 provides more adjustment space, allowing for adaptation even if the elevator door end cap deforms, thus improving structural adaptability. Additionally, the deformed structure obtained through pressing can serve as a reinforcing structure at the bottom of the mounting plate body 1, resulting in higher overall structural strength and reducing the likelihood of bending deformation due to the weight of the elevator door panel 7, thereby extending its service life. Moreover, connecting holes are provided on both sides of the folded edge 11 and the clearance notch 112, facilitating the subsequent installation of the elevator door panel 7 using the connecting parts 2.

[0019] Figure 2 This is a structural diagram illustrating the mating structure between a centrally pressed elevator door mounting plate and an elevator door panel according to this utility model. Figure 1 and Figure 2As shown, the mounting plate body 1 is also provided with clearance holes 12. Each connecting hole corresponds to a clearance hole 12. Furthermore, in the horizontal direction, each clearance hole 12 is located beside the corresponding connecting hole. This ensures that when the elevator door panel 7 is subsequently installed to the connecting hole of the folded edge 11 via the connector 2, the end of the connector 2 can be located within the clearance hole 12 in the horizontal direction. This prevents the mounting plate body 1 from interfering with the installation and removal of the connector 2, meeting installation requirements while facilitating the installation and removal of the connector 2. It is worth noting that the connector 2 is a bolt, which connects the elevator door panel 7 and the folded edge 11 together. The bolt nut is located in the clearance hole 12 in the horizontal direction, facilitating bolt installation.

[0020] More specifically, a number of adjusting shims 3 are provided between the mounting surface 111 of the folded edge 11 and the top end face of the elevator door panel 7. The number of adjusting shims 3 is adjusted according to the actual installation requirements. By increasing or decreasing the number of adjusting shims 3, the level of the elevator door panel 7 after installation is ensured, thereby ensuring the stable operation of the elevator door panel 7.

[0021] More specifically, two upper hanging wheels 4 are rotatably installed on one side of the upper part of the hanging plate body 1. The two upper hanging wheels 4 are respectively set at both ends of the hanging plate body 1, so that when the hanging plate body 1 is hung on the track by the upper hanging wheels 4, the hanging plate body 1 can maintain stable force, ensure the stability of the hanging plate body 1 when moving, and also ensure the load-bearing capacity of the hanging plate body 1.

[0022] More specifically, a roller assembly 5 is rotatably mounted on one side of the lower part of the mounting plate body 1. This roller assembly 5 includes several rollers spaced horizontally, and these rollers roll on a track. The roller assembly 5 automatically compensates for track errors, achieving horizontal support and rolling guidance, reducing friction, buffering vibrations during operation, and improving performance during high-speed operation. It is worth noting that the structure of the roller assembly 5 in this embodiment includes, but is not limited to, the roller assemblies 5 found on existing elevator door mounting plates. A suitable roller assembly 5 can be selected and installed according to actual needs; therefore, the specific structure of the roller assembly 5 will not be described in detail here.

[0023] Figure 3 This is a structural diagram illustrating the fit between a centrally pressed elevator door mounting plate and a track according to this utility model. Figure 1 and Figure 3As shown, an anti-detachment component 6 is also provided on one side of the mounting plate body 1. The anti-detachment component 6 prevents the installed elevator door mounting plate from detaching from the track, improving the safety of elevator operation. Preferably, the anti-detachment component 6 and the upper hanging wheel 4 are located on the same side of the mounting plate body 1, which facilitates the cooperation between the anti-detachment component 6 and the track and makes more reasonable use of space. Furthermore, the anti-detachment component 6 includes an upper anti-detachment hook 61 and a lower anti-detachment hook 62. The upper anti-detachment hook 61 bends downward and the lower anti-detachment hook 62 bends upward. A track is provided on the bottom plate of the upper frame. The upper anti-detachment hook 61 and the lower anti-detachment hook 62 are respectively located above and below the track. By hooking the track with the upper anti-detachment hook 61 and the lower anti-detachment hook 62, the mounting plate body 1 is prevented from falling off the track during operation, making the structure more stable and reliable.

[0024] More specifically, the upper anti-detachment hook 61 in the anti-detachment component 6 is an integral structure with the hanging plate body 1, which improves the connection strength between the upper anti-detachment hook 61 and the hanging plate body 1. Furthermore, the upper anti-detachment hook 61 is formed by stamping and bending the hanging plate body 1, which facilitates processing and manufacturing.

[0025] More specifically, the lower anti-detachment hook 62 in the anti-detachment component 6 is detachably installed on the mounting plate body 1, making the structure of the lower anti-detachment hook 62 more flexible. At this time, the lower anti-detachment hook 62 includes an anti-detachment hook body 621 and an installation component 622. The installation component 622 enables the anti-detachment hook body 621 to be detached and installed on the mounting plate body 1. Thus, when removing and installing the elevator door mounting plate, the elevator door mounting plate can be directly removed from the side of the track by removing and installing the lower anti-detachment hook 62. This effectively avoids the problem that the existing fixed upper anti-detachment hook 61 and lower anti-detachment hook 62 structure requires the elevator door mounting plate to be moved to the end of the track to be removed. The removal and installation are more convenient and conducive to the maintenance and repair of the elevator. At this time, a through hole 13 and a fixing hole located next to the through hole 13 are provided on the mounting plate body 1. One end of the anti-detachment hook 621 passes through the through hole 13 and extends to the same side as the upper anti-detachment hook 61, so that the anti-detachment hook 621 can subsequently cooperate with the track. The other end of the anti-detachment hook 621 is located on the side opposite to the upper anti-detachment hook 61 and is connected to the fixing hole through the mounting part 622, which meets the design requirement of the lower anti-detachment hook 62 being disassembled and installed on the mounting plate body 1. Preferably, the mounting part 622 is a bolt, which facilitates the disassembly and assembly of the lower anti-detachment hook 62 on the mounting plate body 1.

[0026] The elevator door mounting plate provided in this embodiment includes a mounting plate body 1. By pressing the middle of the folded edge 11 at the bottom of the mounting plate body 1, a concave clearance notch 112 is formed in the middle of the mounting surface 111 of the folded edge 11. This reduces the contact area between the folded edge 11 and the top end face of the elevator door panel 7 when connecting the folded edge 11 to the elevator door panel 7. This reduces the mounting surface 111 on the folded edge 11 that needs to be processed with high precision, effectively reducing the processing difficulty and facilitating manufacturing. It also allows for shaping and correction of the folded edge 11 during pressing, resulting in higher processing efficiency. Furthermore, the deformation structure generated by pressing can be used as a reinforcing structure for the elevator door mounting plate, improving the overall structural strength and preventing bending deformation due to excessive weight of the elevator door panel 7. In addition, the concave clearance notch 112 provides more space for debugging and installation, better adapting to possible deformation of the elevator door end cap, resulting in better structural adaptability and easier installation and debugging.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
