Description

Technical Field

[0001] This utility model belongs to the field of elevator-related technology, and in particular relates to an upper beam assembly and an elevator. Background Technology

[0002] With the proliferation of high-rise buildings, elevators have become an indispensable vertical transportation tool in modern life. However, the installation and maintenance of elevators also present numerous challenges. Improving the efficiency of elevator installation and maintenance is not only related to passenger safety but also directly affects the efficiency and cost of building management. The elevator maintenance industry also faces problems such as low operational efficiency and cumbersome maintenance processes.

[0003] Currently, elevator sheave covers are typically bolted to the upper and lower parts of the upper beam body. When installing or replacing the sheave on the upper beam body, installers need to use a wrench to tighten and loosen the bolts; similarly, when the sheave requires maintenance, maintenance personnel also need to use a wrench to loosen the bolts before they can perform lubrication. This results in low installation and maintenance efficiency. Utility Model Content

[0004] In view of this, it is necessary to provide a beam assembly and elevator that facilitates the installation and maintenance of the sheave module.

[0005] A beam assembly includes a beam body, a sheave module mounted on the beam body, and an upper cover. The upper cover is correspondingly disposed above the sheave module and is detachably connected to the beam body.

[0006] The upper beam body is equipped with a first opening clip, and the upper cover part is inserted into the first opening clip and tightly fitted with the first opening clip, for fixing the upper cover to the upper beam body.

[0007] Understandably, since the upper cover is assembled and connected to the upper beam body by inserting and tightly fitting with the first opening clip, the upper cover can be installed or removed from the upper beam body simply by inserting or removing it from the first opening clip. This makes the operation convenient and facilitates the installation and maintenance of the rope wheel module on the upper beam body.

[0008] In one embodiment, the first opening clip includes a first spring, a second spring, and a connecting piece, wherein the connecting piece is connected to the first spring and the second spring respectively;

[0009] The upper protective cover is inserted between the first and second spring sheets and is elastically held by the first and second spring sheets.

[0010] It is understandable that the elastic clamping of the upper cover by the first and second springs is used to achieve the assembly connection between the upper cover and the first opening clip. This simplifies the structure of the first opening clip and facilitates the assembly of the upper cover onto the first opening clip.

[0011] In one embodiment, the first spring, the connecting piece, and the second spring are connected as a single unit.

[0012] It is understandable that by connecting the first spring, the connecting piece, and the second spring into one piece, the first opening clip can be formed by bending a flat plate, which facilitates the production and manufacturing of the first opening clip.

[0013] In one embodiment, the first spring and the second spring are respectively placed on both sides of the connecting piece, and a first clamping opening with an upward opening is formed between the first spring and the second spring, the first clamping opening being able to clamp the upper protective cover;

[0014] The connecting piece is connected to the upper beam body.

[0015] It is understandable that the upper cover is clamped by forming an opening with the first and second springs facing the first clamping port, so that the upper cover can be aligned downwards with the first clamping port and inserted to achieve assembly. This facilitates the assembly of the upper cover on the first opening clamp.

[0016] In one embodiment, the upper beam assembly further includes a lower cover, which is correspondingly disposed to the rope pulley module and is disposed below the corresponding rope pulley module and is detachably connected to the upper beam body;

[0017] The upper beam body is also equipped with a second opening clip, and the lower cover part is inserted into the second opening clip and tightly fitted with the second opening clip to fix the lower cover to the upper beam body.

[0018] Understandably, since the lower cover is assembled and connected to the upper beam body by inserting and tightly fitting with the second opening clip, the lower cover can be installed or removed from the upper beam body simply by inserting or removing it from the second opening clip. This makes the operation convenient and further facilitates the installation and maintenance of the rope wheel module on the upper beam body.

[0019] In one embodiment, the lower cover includes a first split cover and a second split cover that are independently disposed of with respect to each other;

[0020] Along the width direction of the upper beam body, the first split cover and the second split cover are respectively inserted into the second opening clips facing the corresponding rope wheel modules, so that the first split cover and the second split cover are connected.

[0021] It is understandable that using separate first and second covers to assemble and disassemble the lower cover and the second opening clip ensures that the assembly and disassembly of the lower cover on the second opening clip is not affected by the rope wheel module.

[0022] In one embodiment, the lower cover further includes a rope deflector that extends through the first split cover and the second split cover;

[0023] The portion of the rope-blocking rod extending beyond the first split cover is engaged and limited by a first cotter pin, and the portion of the rope-blocking rod extending beyond the second split cover is engaged and limited by a second cotter pin.

[0024] It is understandable that the first and second split covers are limited by the rope retaining rod, the first cotter pin, and the second cotter pin after docking. This can improve the stability of the first and second split covers after docking, so as to meet the usage requirements of the upper beam assembly for the lower cover.

[0025] In one embodiment, the second opening clip includes a spring clip and a mounting portion, wherein the spring clip is fixed to the upper beam body via the mounting portion;

[0026] The lower protective cover is inserted into the spring clip and is elastically held by the spring clip.

[0027] In one embodiment, the mounting part includes a first folding plate and a second folding plate that are connected to each other and form a preset included angle, wherein the first folding plate is connected to the upper beam body;

[0028] The spring clip includes a first spring clip, a connecting piece, and a second spring clip connected in sequence. The spring clip can be mounted on the second folding plate through the connecting piece. A second clamping opening with a horizontal opening is formed between the first spring clip and the second spring clip, and the second clamping opening can clamp the lower cover.

[0029] In addition, this application also provides an elevator, including the aforementioned upper beam assembly.

[0030] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0031] The upper beam assembly and elevator for which this application seeks protection achieve assembly connection of the upper cover on the upper beam body by inserting it into the first opening clip and then tightly fitting it with the first opening clip. This makes it easy to install or remove the upper cover from the upper beam body simply by inserting or removing it from the first opening clip, which is convenient and facilitates the installation and maintenance of the rope wheel module on the upper beam body.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figures 1 to 3 , Figure 5 As shown, the upper beam assembly 100 provided in this application includes an upper beam body 10, a sheave module 20 mounted on the upper beam body 10, and an upper cover 30. The upper cover 30 is correspondingly disposed above the sheave module 20 and is detachably connected to the upper beam body 10. A first opening clip 40 is mounted on the upper beam body 10, and part of the upper cover 30 is inserted into and tightly fitted with the first opening clip 40 to fix the upper cover 30 to the upper beam body 10. Here, the number of sheave modules 20 is configured as two, arranged on both sides of the upper beam body 10 along its length. It should be noted that the number of sheave modules 20 in the upper beam assembly 100 of this application can also be one or three, which will not be elaborated here.

[0045] As can be seen from the above, since the upper cover 30 is tightly fitted to the first opening clip 40 after being inserted, the upper cover 30 is assembled and connected to the upper beam body 10. This allows the upper cover 30 to be installed or removed from the upper beam body 10 simply by inserting or removing it from the first opening clip 40, making the operation convenient and facilitating the installation and maintenance of the rope pulley module 20 on the upper beam body 10. Here, the upper cover 30 is inserted or removed from the first opening clip 40 along the height direction of the upper beam body 10. It should be noted that the above-mentioned maintenance of the rope pulley module 20 specifically refers to the lubrication and maintenance of the rope pulley module 20.

[0046] like Figure 5 As shown, the first opening clamp 40 includes a first spring piece 41, a second spring piece 42, and a connecting piece 43. The connecting piece 43 is connected to the first spring piece 41 and the second spring piece 42 respectively. The upper cover 30 is partially inserted between the first spring piece 41 and the second spring piece 42 and is elastically clamped by them, thus achieving the assembly connection between the first opening clamp 40 and the upper cover 30. In other words, the first opening clamp 40 can utilize the elastic deformation of the first spring piece 41 and the second spring piece 42 to clamp the upper cover 30 inserted between them. This simplifies the structure of the first opening clamp 40 and facilitates the assembly of the upper cover 30 onto the first opening clamp 40. Here, when the upper cover 30 is not inserted into the first opening clip 40, the first spring piece 41 and the second spring piece 42 on the first opening clip 40 abut against each other, which can increase the force of the first opening clip 40 when it elastically clamps the upper cover 30. It should be noted that the connecting piece 43 of the first opening clip 40 can be fixed to the upper beam body 10 by screwing or welding.

[0047] like Figure 5 As shown, the first spring piece 41, the connecting piece 43, and the second spring piece 42 are connected as a single unit, allowing the first opening clamping component 40 to be formed by bending a flat plate, thus facilitating its production. Specifically, the first opening clamping component 40 can be configured as a metal part such as a carbon steel plate or an aluminum alloy plate.

[0048] like Figure 1 , 5As shown, the first spring piece 41 and the second spring piece 42 are respectively placed on both sides of the connecting piece 43, and a first clamping opening 401 with an upward opening is formed between the first spring piece 41 and the second spring piece 42. The first clamping opening 401 can clamp the upper cover 30; wherein, the connecting piece 43 is connected to the upper beam body 10. This allows the upper cover 30 to be assembled by aligning it downward or from the side with the first clamping opening 401 in a way that can be inserted or slid in. This facilitates the assembly of the upper cover 30 on the first opening clip 40 without the need for additional mounting parts or adjustments to the cover structure. Here, the opening of the first clamping opening 401 is set upward, specifically, the opening direction of the first clamping opening 401 is upward in the vertical direction. It is understood that in other embodiments, the opening direction of the first clamping opening 401 formed between the first spring 41 and the second spring 42 may be downward, or it may be horizontally oriented towards the inner or outer side of the upper beam body 10. Accordingly, the first opening clip 40 may be fixed to the upper beam body 10 by the first spring 41 or the second spring 42, or it may be fixed to the upper beam body 10 by an additional mounting part.

[0049] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, the number of first opening clips 40 is configured to be multiple; at least two of the multiple first opening clips 40 are arranged on both sides of the upper beam body 10 in the width direction. This allows the upper beam body 10 to be jointly fixed with the upper cover 30 using multiple first opening clips 40, thereby improving the stability of the upper cover 30 when assembled on the upper beam body 10. Here, the number of first opening clips 40 is configured to be two, and the length of the first opening clips 40 can be adapted to the length of the upper cover 30. It can be understood that in other embodiments, the number of first opening clips 40 may also be three, four, or even more, and the installation position of the first opening clips 40 on the upper beam body 10 can be specifically arranged according to the usage requirements, which will not be elaborated here.

[0050] like Figures 1 to 3 , Figure 5 As shown, the upper beam assembly 100 also includes a lower cover 50, which is correspondingly disposed to the rope pulley module 20. The lower cover 50 is located below the corresponding rope pulley module 20 and is detachably connected to the upper beam body 10. A second opening clip 60 is also installed on the upper beam body 10. Part of the lower cover 50 is inserted into and tightly fitted with the second opening clip 60 to fix the lower cover 50 to the upper beam body 10. Similarly, the lower cover 50 can be installed or removed from the upper beam body 10 simply by inserting or removing it from the second opening clip 60, making the operation convenient and further facilitating the installation and maintenance of the rope pulley module 20 on the upper beam body 10.

[0051] like Figure 1 , Figure 5 As shown, the lower cover 50 includes a first split cover 51 and a second split cover 52 that are independently arranged. Along the width direction of the upper beam body 10, the first split cover 51 and the second split cover 52 are respectively inserted into the second opening clip 60 towards the corresponding rope wheel module 20, so that the first split cover 51 and the second split cover 52 are connected. That is, the lower cover 50 is detached and assembled on the second opening clip 60 through the split structure of the first split cover 51 and the second split cover 52, so that the detachment and assembly of the lower cover 50 on the second opening clip 60 is not affected by the rope wheel module 20. Here, the first split cover 51 and the second split cover 52 are configured with the same structure, and the first split cover 51 and the second split cover 52 can be inserted or removed from the second opening clip 60 along the width direction of the upper beam body 10, which facilitates the production and manufacturing of the lower cover 50. It should be noted that the docking between the first split cover 51 and the second split cover 52 mentioned above specifically refers to the mutual abutment between the first split cover 51 and the second split cover 52.

[0052] like Figure 1 , Figure 4 As shown, the lower protective cover 50 also includes a rope-blocking rod 53, which passes through the first split cover 51 and the second split cover 52. The portion of the rope-blocking rod 53 extending beyond the first split cover 51 is engaged and limited by a first cotter pin 54, and the portion extending beyond the second split cover 52 is engaged and limited by a second cotter pin 55. In other words, after the first split cover 51 and the second split cover 52 are partially inserted into the second opening clip 60 and aligned, the rope-blocking rod 53 can first pass through the first split cover 51 and the second split cover 52, and then the first cotter pin 54 and the second cotter pin 55 can be used to engage and limit the rope-blocking rod 53. This improves the stability of the first split cover 51 and the second split cover 52 after alignment, meeting the usage requirements of the lower protective cover 50 in the upper beam assembly 100. Here, three rope-blocking rods 53 are configured, positioned to avoid the rope pulley module 20. Specifically, they can be arranged in a triangle, providing three limiting and fixing points between the first split cover 51 and the second split cover 52. This further improves the stability after the first split cover 51 and the second split cover 52 are connected. It is understood that in other embodiments, the number of rope-blocking rods 53 can also be two, four, five, or even more, which will not be elaborated here.

[0053] like Figure 4 As shown, the second opening clip 60 includes a spring clip 61 and a mounting part 62. The spring clip 61 is fixed to the upper beam body 10 through the mounting part 62. The lower cover 50 is partially inserted into the spring clip 61 and is elastically clamped by the spring clip 61.

[0054] like Figure 4 As shown, the mounting part 62 includes a first folding plate 621 and a second folding plate 622 connected to each other and forming a preset included angle. The first folding plate 621 is connected to the upper beam body 10. The spring clip part 61 includes a first spring clip part 611, a connecting piece part 612, and a second spring clip part 613 connected in sequence. The spring clip part 61 can be mounted on the second folding plate 622 through the connecting piece part 612. A second clamping port 601 with a horizontal opening is formed between the first spring clip part 611 and the second spring clip part 613. The second clamping port 601 can clamp the lower cover 50. That is to say, the mounting part 62 is configured as a bent plate structure. Here, the number of first folding plates 621 is configured to be two. The two first folding plates 621 are set on both sides of the second folding plate 622 and connected to the second folding plate 622. One of the first folding plates 621 can be connected to the upper beam body 10 by means of threads, and the connecting piece part 612 can be connected to the first folding plate 621 by means of welding. It should be noted that the opening direction of the second clamping port 601 on the second opening card 60 can also be set vertically downward, which will not be elaborated here.

[0055] like Figure 6 , Figure 7 As shown, multiple second opening clips 60 are configured, with each second opening clip 60 extending along the width direction of the upper beam body 10. This allows each second opening clip 60 on the upper beam body 10 to meet the requirement of fixing the first split cover 51 and the second split cover 52 on the lower cover 50. Furthermore, using multiple second opening clips 60 to jointly support the lower cover 50 improves the stability of the lower cover 50 during assembly on the upper beam body 10. Here, two second opening clips 60 are configured, with the third second opening clip 60 spanning the upper beam body 10. It is understood that in other embodiments, the number of second opening clips 60 can also be four, with two second opening clips 60 supporting the first split cover 51 and the remaining two supporting the second split cover 52. Alternatively, one second opening clip 60 can be configured, using one second opening clip 60 to jointly support the first split cover 51 and the second split cover 52; this will not be elaborated upon here.

[0056] In addition, this application also provides an elevator, including the aforementioned upper beam assembly 100.

[0057] 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.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
