Counterweight assembly and elevator

Abstract

The counterweight assembly and elevator provided in this application include a counterweight frame and a counterweight. The counterweight frame encloses a cavity. The counterweight is housed within the cavity and supported by the counterweight frame. The counterweight includes a water tank, which is detachably installed within the counterweight frame. The water tank has a water storage chamber, which is configured as an independent chamber and can be filled with water. In other words, the counterweight assembly of this application uses a water tank filled with water to construct the counterweight. Since water can be obtained on-site, there is no need to ship prefabricated counterweight blocks from the factory, thus significantly saving logistics costs. Furthermore, during on-site installation, an empty water tank can be installed into the counterweight frame first, followed by water filling, greatly reducing the labor intensity during the handling phase and improving installation convenience.

Description

Technical Field

[0001] This utility model belongs to the technical field of elevator counterweights, and in particular relates to a counterweight component and an elevator. Background Technology

[0002] The counterweight is the core balancing component of an elevator. It is connected to the elevator car via steel cables and moves in the opposite direction. It uses its own weight to effectively counteract the weight of the elevator car and part of the load, thereby significantly reducing the load on the drive motor and ultimately achieving the comprehensive goals of energy saving, efficiency improvement and enhanced safety.

[0003] Currently, the counterweights in existing elevators are generally made of cast iron or cement, which are large in mass and difficult to transport, causing many inconveniences for on-site installation. To address this issue, existing technologies, such as the patent with publication number CN104709797B, propose a "novel elevator counterweight." This design attempts to improve the convenience of handling and installation by combining materials of different densities and using asymmetrical first and second mass blocks. However, in practical applications, this solution still fails to fundamentally solve the problem of inconvenient installation and handling, still relying on high-intensity manual operation, and logistics costs remain high. Utility Model Content

[0004] Therefore, it is necessary to provide a counterweight component and elevator that are easy to transport and install.

[0005] A counterweight assembly, the counterweight assembly comprising: The double-frame structure encloses and forms a cavity. The counterweight is housed within the accommodating cavity and supported by the counterweight frame. The counterweight includes a water tank, which is detachably installed within the counterweight frame. The water tank has a water storage chamber configured as an independent chamber and capable of being filled with water.

[0006] Understandably, using a water tank filled with water to construct the counterweight of the counterweight component significantly reduces logistics costs because water can be obtained on-site, eliminating the need to ship prefabricated counterweight blocks from the factory. Furthermore, during on-site installation of the counterweight component, an empty water tank can be installed into the counterweight frame first, followed by water filling, which greatly reduces the labor intensity during the handling phase and improves installation convenience.

[0007] In one embodiment, the number of water tanks is configured to be multiple, and the multiple water tanks are divided into multiple drainage tank groups; Along the height direction of the counterweight frame, multiple rows of water tank assemblies are arranged at intervals within the counterweight frame and are supported by the counterweight frame respectively.

[0008] Understandably, using multiple water tanks to construct the counterweight of this pair of heavy components effectively reduces the structural size of a single water tank through this distributed design. This not only further reduces the cost of logistics and transportation, but also makes on-site handling and installation operations more flexible and convenient.

[0009] In one embodiment, a partition is connected to the counterweight frame; The adjacent rows of water tanks are separated by the partition, and the partition can support the water tanks above it.

[0010] Understandably, by using partitions to directly support and distribute the load of the water tank assembly, this design can meet the load-bearing requirements of the counterweight frame while facilitating the subsequent disassembly and replacement of individual water tanks.

[0011] In one embodiment, the partition includes a first crossbeam, a second crossbeam, and a support plate. The support plate is disposed between the first crossbeam and the second crossbeam and is connected to both the first crossbeam and the second crossbeam. Furthermore, the first crossbeam, the support plate, and the second crossbeam together serve to support the water tank assembly. The first crossbeam and the second crossbeam are located on opposite sides of the counterweight frame and are respectively connected to the counterweight frame.

[0012] In one embodiment, a limiting frame is also connected to the counterweight frame. The limiting frame is correspondingly arranged with the water tank group, and the water tank group can be limited within the counterweight frame by the corresponding limiting frame.

[0013] Understandably, by using a limit frame to reliably confine the water tank within the counterweight frame, the displacement or fall of the water tank due to vibration or inertia during the lifting and lowering process of the counterweight assembly can be prevented, thereby ensuring the stability and safety of the counterweight assembly's operation.

[0014] In one embodiment, the limiting frame includes a third crossbeam and a fourth crossbeam, which are disposed on opposite sides of the counterweight frame and are detachably connected to the counterweight frame.

[0015] Understandably, by setting the third and fourth crossbeams to be detachably connected to the counterweight frame, the limiting frame can reliably limit the water tank while its entire or partial structure can be easily disassembled and assembled. This design ensures that when the water tank needs to be maintained or replaced, the fixed setting of the limiting frame will not cause any obstruction, effectively balancing operational stability and maintenance convenience.

[0016] In one embodiment, the number of water tanks in the water tank group is configured to be multiple; Along the width direction of the counterweight frame, the water tanks in each row of the water tank group are arranged sequentially.

[0017] Understandably, constructing the water tank assembly using multiple water tanks can further reduce the structural size of a single water tank. This not only further reduces costs during the logistics and transportation phase, but also makes on-site handling and installation operations more flexible and convenient.

[0018] In one embodiment, the water tank includes a tank body and a top cover, the top cover being detachably mounted on the tank body for controlling the opening / closing of the tank body; A drain valve is installed on the box.

[0019] Understandably, using a drain valve to drain the water tank makes subsequent maintenance and replacement of the water tank easier.

[0020] In one embodiment, the counterweight frame includes a lower beam that houses a weight block; The lower beam and the weight block together support the water tank located above it.

[0021] Understandably, by setting up weight blocks to work with the lower beam to support the water tank, the support contact area at the bottom of the water tank is increased, making the force distribution more even and improving structural stability. On the other hand, the weight blocks themselves also provide some counterweight, which helps to reduce the overall height of the counterweight component while ensuring the same total counterweight, thus freeing up more vertical travel space for elevator operation.

[0022] In addition, this application also provides an elevator, including the counterweight component described above.

[0023] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The counterweight assembly and elevator claimed in this application utilize a water tank filled with water to construct the counterweight of the counterweight assembly. Since water can be obtained on-site, there is no need to ship prefabricated counterweight blocks from the factory, thus significantly saving logistics costs. In addition, during on-site installation of the counterweight assembly, an empty water tank can be installed into the counterweight frame first, and then water can be added, which greatly reduces the labor intensity during the handling phase and improves the ease of installation.

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.

[0034] 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.

[0035] like Figures 1 to 3 As shown, the counterweight assembly 100 provided in this application includes a counterweight frame 10 and a counterweight 20. The counterweight frame 10 encloses a receiving cavity 110. The counterweight 20 is housed within the receiving cavity 110 and supported by the counterweight frame 10. The counterweight 20 includes a water tank 21, which is detachably installed within the counterweight frame 10. The water tank 21 has a water storage chamber (not shown), which is configured as an independent chamber and can be filled with water. In other words, the counterweight assembly 100 of this application uses a water tank 21 filled with water to construct the counterweight of the counterweight assembly 100. Since water can be obtained on-site, there is no need to ship prefabricated counterweight blocks from the factory, thus significantly saving logistics costs. In addition, during on-site installation, the empty water tank 21 can be installed into the counterweight frame 10 first, and then water can be added, greatly reducing the labor intensity during the handling stage and improving installation convenience.

[0036] like Figure 1 , Figure 2 As shown, in one embodiment, the counterweight frame 10 includes an upper beam 11, a lower beam 12 disposed opposite to the upper beam 11, and two straight beams 13 disposed between the upper beam 11 and the lower beam 12 and respectively connected to the upper beam 11 and the lower beam 12; and the upper beam 11, the two straight beams 13 and the lower beam 12 together enclose the aforementioned accommodating cavity 110.

[0037] The upper beam 11 is equipped with a counterweight wheel 111, and a protective cover 112 is installed above the counterweight wheel 111. Specifically, the protective cover 112 covers the part of the counterweight wheel 111 that protrudes upward from the upper beam 11.

[0038] like Figure 4 As shown, the lower beam 12 houses the weight block 121, and the lower beam 12 and the weight block 121 together support the water tank 21 above it. This increases the support contact area at the bottom of the water tank 21, making the force more even and improving the structural stability. On the other hand, the weight block 121 itself also provides some counterweight, which helps to reduce the overall height of the counterweight component 100 while ensuring the same total counterweight, thus freeing up more vertical travel space for elevator operation.

[0039] Here, the lower beam 12 is configured as a U-shaped structure with bent edges. Multiple weight blocks 121 are arranged sequentially in the concave cavity 122 of the lower beam 12. Furthermore, the two bent edges 123 of the lower beam 12 are at the same height as the weight blocks 121, so that the two bent edges 123 of the lower beam 12 and a row of weight blocks 121 can simultaneously contact the bottom of the water tank 21 above it, thereby achieving the purpose of supporting the water tank 21.

[0040] It should be noted that the aforementioned weight block 121 can be made of cast iron or cement. Since the overall volume of the weight block 121 is not large, the mass of each weight block 121 is not high, and it will not have a significant impact on logistics and handling during installation.

[0041] like Figure 5 As shown, in one embodiment, the water tank 21 includes a tank body 211 and a top cover 212, the top cover 212 being detachably mounted on the tank body 211 for controlling the opening / closing of the tank body 211.

[0042] Here, the top cover 212 is threaded to the housing 211, thereby achieving a detachable connection between the top cover 212 and the housing 211.

[0043] The tank 211 is equipped with a drain valve 213. Before subsequent maintenance or replacement of the water tank 21, the operator can drain the water accumulated in the water storage chamber of the water tank 21 through the drain valve 213, thereby effectively reducing the overall weight of the water tank 21 and making it easier and safer to remove the water tank 21 from the counterweight frame 10.

[0044] like Figure 1 As shown, in one embodiment, the number of water tanks 21 is configured as multiple, and the multiple water tanks 21 are divided into multiple drainage tank groups 210. Along the height direction Z of the counterweight frame 10, the multiple drainage tank groups 210 are arranged at intervals within the counterweight frame 10 and are supported by the counterweight frame 10 respectively. That is to say, this embodiment uses multiple water tanks 21 to constitute the counterweight of the counterweight component 100. This distributed design effectively reduces the structural size of a single water tank 21, which not only further reduces the cost of logistics and transportation, but also makes on-site handling and installation operations more flexible and convenient.

[0045] Here, the counterweight assembly 100 has 4 rows of water tanks 210. Of course, in other embodiments, the water tanks 210 in the counterweight frame 10 can also have 3, 5, 6, or even more rows of drainage, depending on the capacity of the water storage chamber in each water tank 21 and the load requirements of the counterweight assembly 100, which will not be elaborated here.

[0046] like Figure 1 , Figure 2As shown, in one embodiment, a partition 30 is connected to the counterweight frame 10; adjacent drainage tank groups 210 are separated by the partition 30, and the partition 30 can support the water tank group 210 above it. That is to say, the counterweight component 100 of this embodiment supports and distributes the load of the water tank group 210 by using the partition 30. This design can meet the load-bearing requirements of the counterweight frame 10 while providing convenience for the subsequent disassembly and replacement of individual water tanks 21.

[0047] like Figure 6 As shown, the partition 30 includes a first crossbeam 31, a second crossbeam 32, and a support plate 33. The first crossbeam 31 and the second crossbeam 32 are located on opposite sides of the counterweight frame 10 and are respectively connected to the counterweight frame 10. The support plate 33 is located between the first crossbeam 31 and the second crossbeam 32 and is respectively connected to the first crossbeam 31 and the second crossbeam 32. Furthermore, the first crossbeam 31, the support plate 33, and the second crossbeam 32 are used together to support the water tank assembly 210. This can increase the contact area between the partition 30 and the water tank assembly 210 when the partition 30 supports the water tank assembly 210, thereby improving the stability of the water tank assembly 210 placed in the counterweight frame 10 through the partition 30.

[0048] Here, the first crossbeam 31, the second crossbeam 32, and the support plate 33 are all configured as bent sheet metal. Specifically, the first crossbeam 31, the second crossbeam 32, and the support plate 33 are all configured as U-shaped bent parts. The U-shaped openings of the first crossbeam 31 and the second crossbeam 32 are arranged opposite to each other, and the two side walls of the U-shaped opening end of the support plate 33 are respectively connected to the bottom of the U-shaped opening of the first crossbeam 31 and the second crossbeam 32.

[0049] like Figure 2 , Figure 3 As shown, a limiting frame 40 is also connected to the counterweight frame 10. The limiting frame 40 is correspondingly set with the water tank assembly 210, and the water tank assembly 210 can be limited within the counterweight frame 10 by the corresponding limiting frame 40. This can prevent the water tank 21 from shifting or falling due to vibration or inertia during the lifting and lowering operation of the counterweight assembly 100, thereby ensuring the stability and safety of the counterweight assembly 100.

[0050] like Figure 3 As shown, the limiting frame 40 includes a third crossbeam 41 and a fourth crossbeam 42. The third crossbeam 41 and the fourth crossbeam 42 are located on two opposite sides of the counterweight frame 10 and are detachably connected to the counterweight frame 10, so that the limiting frame 40 can reliably limit the water tank 21 while its whole or part of the structure can be easily disassembled and assembled. This design ensures that when the water tank 21 needs to be maintained or replaced, it will not be obstructed by the fixed setting of the limiting frame 40, effectively balancing operational stability and maintenance convenience.

[0051] Here, the two ends of the third crossbeam 41 and the fourth crossbeam 42 are respectively abutted against the two straight beams 13 of the counterweight frame 10 by pads 43, and then bolts (not shown) are used to connect and fix the three together, which facilitates the assembly and disassembly of the third crossbeam 41 and the fourth crossbeam 42 on the counterweight frame 10. Specifically, in one embodiment, the third crossbeam 41 and the fourth crossbeam 42 are configured as U-shaped members, with the open ends of the two U-shaped members facing away from each other and both pointing away from the counterweight frame 10.

[0052] like Figure 1 As shown, in one embodiment, the number of water tanks 21 in the water tank assembly 210 is configured to be multiple; and, along the width direction X of the counterweight frame 10, the water tanks 21 in each water tank assembly 210 are arranged sequentially. That is to say, this embodiment uses multiple water tanks 21 to construct the water tank assembly 210, which can further reduce the structural size of a single water tank 21. This not only further reduces the cost of logistics and transportation, but also makes on-site handling and installation operations more flexible and convenient.

[0053] Here, each row of tank assemblies 210 contains three tanks 21, so that all tanks 21 in the counterweight assembly 100 have the same structural dimensions and achieve a modular design for the tanks 21. Of course, in other embodiments, each row of tank assemblies 210 may contain two, four, or even more tanks 21, which will not be elaborated here.

[0054] In addition, this application also provides an elevator, including the counterweight assembly 100 described above.

[0055] 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.

[0056] 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.
