Description

Technical Field

[0001] This utility model belongs to the field of elevator-related technology, and in particular relates to a high-speed elevator counterweight frame and a high-speed elevator. Background Technology

[0002] The counterweight frame is an important component of the elevator system. It is usually connected to the counterweight steel wire rope using counterweight pulleys to balance the weight of the elevator car.

[0003] With the continuous development of elevator technology, especially for high-speed elevators, the traditional counterweight frame structure has certain limitations in terms of stability, space utilization, and adaptability to specific rope ratios due to the high speed of high-speed elevators during operation. This causes problems such as shaking and faster wear of components during operation, thus affecting the overall performance and safety of high-speed elevators. Utility Model Content

[0004] In view of this, it is necessary to provide a high-speed elevator counterweight frame and a high-speed elevator that are stable and make reasonable use of space.

[0005] A high-speed ladder counterweight frame, comprising:

[0006] The main body of the frame includes an upper beam assembly, a lower beam assembly disposed opposite to the upper beam assembly, and two side beams for connecting the upper beam assembly and the lower beam assembly;

[0007] The counterweight rope head plate is installed inside the upper beam assembly and is used to connect the counterweight wire rope.

[0008] A central vertical beam is positioned between the two side beams, such that a receiving cavity is formed between the central vertical beam and the two side beams, and the two receiving cavities are respectively used to accommodate the counterweight.

[0009] A crossbeam assembly is disposed between the upper beam assembly and the lower beam assembly, and is connected to the intermediate vertical beam and the two side beams respectively;

[0010] A compensating rope hanger is installed on the lower beam assembly and is used to connect the compensating rope.

[0011] It is understandable that using a counterweight rope head plate to connect the counterweight wire rope, using a middle vertical beam to divide the main body of the counterweight frame into two accommodating cavities that can respectively accommodate the counterweight blocks, and installing the compensating rope hanger on the lower beam assembly can help optimize the spatial layout of the high-speed elevator counterweight frame and improve the stability of the high-speed elevator counterweight frame operation, so as to meet the operation requirements of the high-speed elevator with a rope winding ratio of 1:1.

[0012] In one embodiment, the counterweight rope head plate is positioned at the center of the upper beam assembly.

[0013] It is understandable that placing the counterweight rope head plate in the center of the upper beam assembly can improve the overall balance of the counterweight frame when subjected to the force of the counterweight rope head.

[0014] In one embodiment, the mounting position of the compensating rope hanger on the lower beam assembly can be adjusted to a position of left-right balance along the width direction of the high-speed ladder counterweight frame.

[0015] Understandably, the above structural design allows for fine adjustments to the installation position of the compensating rope hanger on the lower beam assembly on-site, facilitating its installation onto the lower beam assembly.

[0016] In one embodiment, the high-speed ladder counterweight frame further includes a U-shaped bending member, which is disposed inside the upper beam assembly and forms a positioning space after being assembled with the upper beam assembly;

[0017] The installation position of the counterweight rope head plate corresponds to the positioning space.

[0018] It is understandable that the counterweight rope head plate is installed by using the positioning space formed after the U-shaped bending part is assembled in the upper beam assembly. This provides a position for the counterweight rope head plate to be installed in the center of the upper beam assembly, and realizes the assembly positioning of the counterweight rope head plate in the upper beam assembly. In this way, the assembly accuracy of the counterweight rope head plate in the upper beam assembly can be guaranteed, so as to ensure the accurate installation of the counterweight rope head plate.

[0019] In one embodiment, the center points of the counterweight rope head plate, the intermediate vertical beam, and the compensating rope hanger are arranged on the same straight line.

[0020] It is understandable that the center points of the counterweight rope head plate, the intermediate vertical beam, and the compensating rope hanger are set on the same straight line. This allows the three components to be installed centrally on the main body of the counterweight frame, thus maintaining the overall balance of the main body of the counterweight frame.

[0021] In one embodiment, the beam assembly includes a first beam assembly;

[0022] Along the height direction of the high-speed ladder counterweight frame, the installation position of the first crossbeam assembly on the middle vertical beam and the two side beams can be adjusted to press and limit the counterweight blocks in the two accommodating cavities.

[0023] It is understandable that, through the above structural design, the first crossbeam assembly can improve the overall structural strength of the counterweight frame and, on the other hand, press and limit the counterweight blocks of different heights in the two accommodating cavities, thus achieving the purpose of dual function.

[0024] In one embodiment, the first crossbeam assembly includes two connecting cross plates. Along the thickness direction of the high-speed ladder counterweight frame, the two connecting cross plates are disposed on the two outer sides of the intermediate vertical beam and the two side beams, and are detachably connected to the intermediate vertical beam and the two side beams respectively.

[0025] A bent plate connects the two connecting horizontal plates.

[0026] In one embodiment, the beam assembly includes a second beam assembly;

[0027] The second crossbeam assembly is located at the end of the middle vertical beam and is connected to the middle vertical beam and the two side beams respectively.

[0028] It is understandable that the above-mentioned structural design enables the second crossbeam assembly to improve the overall strength of the counterweight frame.

[0029] In one embodiment, the high-speed ladder counterweight frame further includes multiple buffer impact plate assemblies;

[0030] Along the width direction of the high-speed ladder counterweight frame, a plurality of the buffer impact plate assemblies are disposed on both sides of the compensating rope hanger and are respectively connected to the lower beam assembly.

[0031] It is understandable that by utilizing the structural characteristics of the buffer impact plate assembly, it can play a buffering role when abnormal situations occur in the high-speed elevator, thereby improving the operational safety of the high-speed elevator.

[0032] This application also claims protection for a high-speed elevator, including the high-speed elevator counterweight frame described above.

[0033] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0034] The high-speed elevator counterweight frame and high-speed elevator claimed in this application use a counterweight rope head plate to connect the counterweight steel wire rope, and use a middle vertical beam to divide the main body of the counterweight frame into two accommodating cavities that can respectively accommodate the counterweight blocks, and install the compensating rope hanger on the lower beam assembly. This can help optimize the spatial layout of the high-speed elevator counterweight frame and improve the stability of the high-speed elevator counterweight frame operation, so as to meet the operation requirements of the high-speed elevator with a rope winding ratio of 1:1.

Detailed Implementation

[0042] 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.

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.

[0044] 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.

[0045] like Figures 1 to 5 As shown, the high-speed ladder counterweight frame 100 provided in this application includes a counterweight frame body 10, a counterweight rope head plate 20, a middle vertical beam 30, a crossbeam assembly 40, and a compensating rope hanger 50. The counterweight frame body 10 includes an upper beam assembly 11, a lower beam assembly 12 disposed opposite to the upper beam assembly 11, and two side beams 13 for connecting the upper beam assembly 11 and the lower beam assembly 12. The counterweight rope head plate 20 is installed on the upper beam assembly 11 and is used to connect the counterweight wire rope (not shown). The middle vertical beam 30 is disposed between the two side beams 13, so that a receiving cavity 101 is formed between the middle vertical beam 30 and the two side beams 13, and the two receiving cavities 101 are used to receive the counterweight blocks (not shown). The crossbeam assembly 40 is disposed between the upper beam assembly 11 and the lower beam assembly 12, and is connected to the middle vertical beam 30 and the two side beams 13 respectively. The compensating rope hanger 50 is installed on the lower beam assembly 12 and is used to connect the compensating rope (not shown).

[0046] As can be seen from the above, the high-speed elevator counterweight frame 100 of this application uses a counterweight rope head plate 20 to connect the counterweight steel wire rope, and uses a middle vertical beam 30 to divide the main body 10 of the counterweight frame into two accommodating cavities 101 that can respectively accommodate the counterweight blocks, and installs the compensating rope hanger 50 on the lower beam assembly 12. This can help optimize the spatial layout of the high-speed elevator counterweight frame 100 and improve the stability of the operation of the high-speed elevator counterweight frame 100, so as to meet the operation requirements of the high-speed elevator with a rope winding ratio of 1:1.

[0047] It should be noted that, since the counterweight frame 100 of the high-speed elevator in this application uses the counterweight rope head plate 20 to connect the counterweight steel wire rope, it is clear to those skilled in the art that the high-speed elevator counterweight frame 100 of this application can be used in a high-speed elevator with a rope ratio of 1:1; and, this application uses the middle vertical beam 30 to divide the main body 10 of the counterweight frame into two accommodating cavities 101 that respectively contain counterweight blocks of equal weight. This allows the high-speed elevator counterweight frame 100 to be heavier overall than other high-speed elevator counterweight frames 100 of the same size by selecting counterweight blocks with a higher density.

[0048] like Figure 1As shown, in one embodiment, two side beams 13 are disposed at both ends of the upper beam assembly 11 and the lower beam assembly 12, and are respectively welded to the upper beam assembly 11 and the lower beam assembly 12 or connected by high-strength bolts, thereby ensuring the firmness of the connection between the two side beams 13 and the upper beam assembly 11 and the lower beam assembly 12.

[0049] like Figure 1 , Figure 5 As shown, in one embodiment, the counterweight rope head plate 20 is positioned at the center of the upper beam assembly 11. This improves the overall balance of the counterweight frame body 10 when subjected to the force of the counterweight rope head plate 20.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the high-speed ladder counterweight frame 100 further includes a U-shaped bending member 21. The U-shaped bending member 21 is disposed within the upper beam assembly 11 and, after being assembled with the upper beam assembly 11, forms a positioning space 102. The installation position of the counterweight rope head plate 20 corresponds to the positioning space 102. This provides a positional positioning for the centered installation of the counterweight rope head plate 20 within the upper beam assembly 11, and achieves the assembly positioning of the counterweight rope head plate 20 within the upper beam assembly 11. This ensures the assembly accuracy of the counterweight rope head plate 20 within the upper beam assembly 11, thereby guaranteeing the accurate installation of the counterweight rope head plate 20. Here, the U-shaped bending piece 21 has two folded edges 211, which are attached to the inner wall 111 of the upper beam assembly 11. Then, the first bolt 201 and the first nut 202, which pass through the folded edges 211 and the upper beam assembly 11, are screwed together to achieve the assembly positioning between the U-shaped bending piece 21 and the upper beam assembly 11. This ensures the accuracy of the assembly position of the U-shaped bending piece 21 in the upper beam assembly 11. The connection of the U-shaped bending piece 21 and the connection of the heavy rope head plate 20 can also be assembled and positioned by means of bolt and nut assembly, which will not be elaborated here.

[0051] In one embodiment, the counterweight rope head plate 20 is connected to the upper beam assembly 11 by welding. This makes the counterweight rope head plate 20 more securely installed in the upper beam assembly 11, which can effectively reduce the swaying of the counterweight rope head plate 20 during the operation of the high-speed elevator and ensure the normal operation of the counterweight wire rope.

[0052] It should be noted that the counterweight rope head plate 20 of this application can be first assembled and positioned in the upper beam assembly 11 using a U-shaped bending piece 21, and then the assembled and positioned counterweight rope head plate 20 can be welded and fixed to the upper beam assembly 11.

[0053] As can be seen from the above, the intermediate vertical beam 30 is positioned between the two side beams 13 and is connected and fixed to the two side beams 13 via the crossbeam assembly 40. This connection between the crossbeam assembly 40 and the two side beams 13 increases the structural strength of the counterweight frame 10. Here, the intermediate vertical beam 30 is positioned in the middle of the two side beams 13, ensuring that the two accommodating cavities 101 separated by the intermediate vertical beam 30 are of the same size.

[0054] like Figure 1 , Figure 3 As shown, in one embodiment, the crossbeam assembly 40 includes a first crossbeam assembly 41. Along the height direction of the high-speed ladder counterweight frame 100, the installation position of the first crossbeam assembly 41 on the middle vertical beam 30 and the two side beams 13 can be adjusted to a balanced position for pressing and limiting the counterweight blocks in the two accommodating cavities 101. That is to say, the first crossbeam assembly 41 in this embodiment can improve the overall structural strength of the counterweight frame body 10 on the one hand, and press and limit the counterweight blocks of different heights in the two accommodating cavities 101 on the other hand, thus achieving a dual purpose.

[0055] like Figure 3 As shown, the first crossbeam assembly 41 includes two connecting cross plates 411. Along the thickness direction of the high-speed elevator counterweight frame 100, the two connecting cross plates 411 are disposed on the outer sides of the intermediate vertical beam 30 and the two side beams 13, and are detachably connected to the intermediate vertical beam 30 and the two side beams 13, respectively. A bent plate 412 connects the two connecting cross plates 411, so that after the two connecting cross plates 411 are respectively attached to the outer sides of the intermediate vertical beam 30 and the two side beams 13, the bent plate 412 can be used to connect the two connecting cross plates 411, making the two connecting cross plates 411 a whole, so as to facilitate subsequent adjustment of the position of the two connecting cross plates 411 in the height direction of the high-speed elevator counterweight frame 100. Here, the number of bent plates 412 is configured as two, and the two bent plates 412 are disposed in two accommodating cavities 101, and are respectively connected to the two connecting cross plates 411 by threads.

[0056] like Figure 3 As shown, in this embodiment, the connecting horizontal plate 411, the intermediate vertical beam 30, and the two side beams 13 can be connected and fixed using a bolt assembly 401. Specifically, the intermediate vertical beam 30 and the two side beams 13 can be provided with different numbers of through holes 110 in the height direction of the high-speed ladder counterweight frame 100. By selecting one of the through hole groups 110 using the bolt assembly 401, the position of the connecting horizontal plate 411, the intermediate vertical beam 30, and the two side beams 13 in the height direction of the high-speed ladder counterweight frame 100 can be adjusted, thereby achieving the purpose of adjusting the installation position of the first horizontal beam assembly 41.

[0057] like Figure 1 , Figure 3As shown, in one embodiment, the crossbeam assembly 40 further includes a second crossbeam assembly 42; the second crossbeam assembly 42 is disposed at the end of the intermediate vertical beam 30 and is connected to the intermediate vertical beam 30 and the two side beams 13 respectively. That is, the second crossbeam assembly 42 is used to fix the intermediate vertical beam 30 between the two side beams 13 and can improve the overall structural strength of the counterweight frame body 10. It should be noted that the specific structure of the second crossbeam assembly 42 and the connection method when connecting it to the intermediate vertical beam 30 and the two side beams 13 respectively can refer to the method of the first crossbeam assembly 41, and will not be elaborated here.

[0058] It should be noted that the middle vertical beam 30 of this application can first be fixed to the two side beams 13 by the second crossbeam assembly 42, and the middle vertical beam 30 can be assembled between the two side beams 13; then the position of the counterweights at different heights in the two accommodating cavities 101 can be adjusted by the first crossbeam assembly 41, and finally the first crossbeam assembly 41 can be fixed to the middle vertical beam 30 and the two side beams 13.

[0059] like Figure 1 , Figure 4 As shown, in one embodiment, along the height direction of the high-speed elevator counterweight 100, the projection of the lower beam assembly 12 toward the compensating rope hanger 50 can cover the compensating rope hanger 50. This allows the counterweight body 10 to be subjected to balanced forces when subjected to the compensating force of the compensating rope hanger 50, further improving the stability of the high-speed elevator counterweight 100 during operation.

[0060] like Figure 4 As shown, in one embodiment, the installation position of the compensating rope bracket 50 on the lower beam assembly 12 can be adjusted along the width direction of the high-speed ladder counterweight frame 100, allowing for fine-tuning of the installation position on the lower beam assembly 12 on-site. This facilitates the installation of the compensating rope bracket 50 onto the lower beam assembly 12. Here, the lower beam assembly 12 has a waist-shaped hole 121, and the lower beam assembly 12 can be fixed to the compensating rope bracket 50 by screwing through the waist-shaped hole 121 and the second bolt 501 and the second nut 502 of the compensating rope bracket 50. This allows the installation position of the compensating rope bracket 50 on the lower beam assembly 12 to be adjusted by utilizing the structural features of the waist-shaped hole 121.

[0061] like Figure 1 As shown, in this embodiment, the center points of the counterweight rope head plate 20, the intermediate vertical beam 30, and the compensating rope bracket 50 are set on the same straight line. This allows the counterweight rope head plate 20, the intermediate vertical beam 30, and the compensating rope bracket 50 to be installed centrally on the counterweight frame body 10, thereby maintaining the overall balance of the counterweight frame body 10.

[0062] like Figure 1 As shown, in one embodiment, the high-speed elevator counterweight frame 100 further includes multiple buffer impact plate assemblies 60. Along the width direction of the high-speed elevator counterweight frame 100, the multiple buffer impact plate assemblies 60 are disposed on both sides of the compensating rope hanger 50 and are respectively connected to the lower beam assembly 12. Thus, the high-speed elevator counterweight frame 100 can utilize the structural characteristics of the buffer impact plate assemblies 60 to provide a buffering effect when abnormal situations occur in the high-speed elevator, thereby improving the operational safety of the high-speed elevator. Here, the number of buffer impact plate assemblies 60 is configured as two. It should be noted that the specific structure of the aforementioned buffer impact plate assemblies 60 and their working principle for providing buffering during abnormal situations in the high-speed elevator can adopt conventional methods of existing technology, and will not be elaborated upon here.

[0063] It should be noted that before manufacturing the high-speed ladder counterweight frame 100 of this application, steel of suitable strength and quality can be used to manufacture the upper beam assembly 11, the intermediate vertical beam 30, the lower beam assembly 12, and the side beams 13 to ensure the overall structural strength and stability of the high-speed ladder counterweight frame 100. The dimensions of each component are precisely machined according to design requirements, especially the bolt hole positions in the upper beam assembly 11 for installing the counterweight rope head plate 20, ensuring their accuracy to guarantee the accurate installation of the counterweight rope head plate 20 within the upper beam assembly 11. During manufacturing, the side beams 13 are first welded to the upper beam assembly 11 and the lower beam assembly 12, respectively, or connected using high-strength bolts to ensure a secure connection. Then, the intermediate vertical beam 30 is installed to accurately divide the counterweight frame body 10 into two accommodating cavities 101. Next, the compensating rope hanger 50 and the buffer impact plate assembly 60 are installed to their corresponding positions in the lower beam assembly 12; finally, the crossbeam assembly 40 is installed.

[0064] In addition, this application also provides a high-speed elevator, including the high-speed elevator counterweight 100 described above.

[0065] 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.

[0066] 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.
