Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to an elevator counterweight system independent of the shaft sidewall and its assembly method. Background Technology

[0002] In existing technologies, home elevators, as a special type of equipment used by high-end customers, not only require safe and convenient use, but also aesthetics and civil engineering adaptability have become mainstream requirements. In existing related technologies, guide rails generally need to be installed on guide rail support frames, and the guide rail support frames are fixed to the shaft to fix the elevator guide device. However, the spacing of the guide device brackets in conventional elevators is 2 meters per step, so multiple guide rail support frames need to be arranged in the shaft to support the guide rails.

[0003] To address the above issues, Chinese utility model patent CN219929321U proposes an elevator counterweight guiding system, which includes a counterweight assembly, a pit fixing seat, a rope head beam assembly, and a guide steel wire rope with adjustable tension via a tensioner assembly. The counterweight assembly includes a pair of vertically arranged counterweight guide rails, counterweight guide shoes with polyurethane linings at both ends of the counterweight guide rails, a bottom support, several counterweights stacked therein, and a limiting member fixed to the counterweight guide rails on the uppermost counterweight. The tensioner assembly is fixed to the pit fixing seat by a lower anti-loosening nut assembly and is adjustablely fastened to the guide steel wire rope by an upper anti-loosening nut assembly. The lower end of the guide steel wire rope is connected to a closed connection end that cooperates with the upper anti-loosening nut assembly by several steel wire rope clamps, and the upper end of the guide steel wire rope is engaged in a wedge-shaped rope head by several steel wire rope clamps.

[0004] However, this type of elevator counterweight guidance system has the following disadvantages: First, although the wire rope has a certain degree of flexibility, it is prone to wear and loosening during long-term operation and frequent use, which leads to frequent inspection and maintenance, thereby increasing the cost of long-term use. Second, as a guide component, the overall structure of the wire rope requires precise and repeated adjustments during the actual installation and adjustment of the counterweight assembly and tensioner assembly to achieve the best tension, making the installation difficult. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an elevator counterweight system and its assembly method that are independent of the shaft sidewall, which enhances civil engineering adaptability and has low maintenance requirements and long-term operating costs.

[0006] To achieve the above objectives, the present invention provides an elevator counterweight system independent of the shaft sidewall, comprising:

[0007] A support frame, the top of which is fixedly connected to the top of the elevator shaft and the bottom of which is fixedly connected to the ground of the elevator shaft, and the support frame has a vertical counterweight space inside.

[0008] The counterweight guide rails are arranged in pairs vertically within the counterweight space and are connected to the support frame as an integral structure.

[0009] Elevator main unit;

[0010] The counterweight assembly is located within the counterweight space, mounted on the counterweight guide rail via a sliding device, and configured to move up and down within the counterweight space along the counterweight guide rail under the drive of the elevator host.

[0011] To improve structural stability and load-bearing capacity, the support frame includes multiple frame units, which are vertically spaced apart. Two or more adjacent frame units are connected to each other as a whole structure by counterweight guide rails.

[0012] To enhance the overall aesthetics of the counterweight system, decorative panels are provided on the outer walls of two or more adjacent frame units, with the edges of the adjacent decorative panels fitting together.

[0013] To reduce the need for on-site processing, the frame unit includes a first crossbeam and a second crossbeam, which are connected by detachable corner brackets to form a rectangular frame structure.

[0014] To reduce installation errors and improve installation stability, the following are also included:

[0015] Ground mounting base, used to fix the bottom frame unit to the floor of the elevator shaft;

[0016] Top mounting bracket is used to secure the top frame unit to the top of the elevator shaft.

[0017] To ensure the flatness of the guide rail connection, the counterweight guide rail is assembled on the support frame in sections, either by a single rigid guide rail or multiple rigid guide rail sections, to form a continuous track structure. Two vertically adjacent rigid guide rails are joined end to end by a connecting plate. Both the connecting plate and the rigid guide rail are provided with fixing holes, and fasteners pass through the fixing holes to fix them to the connecting plate and the rigid guide rail.

[0018] To optimize space utilization, the system also includes a main unit base. An L-shaped bracket is fixedly installed on the counterweight guide rail. The L-shaped bracket is located on the top side of the counterweight guide rail. The main unit base is fixed on the L-shaped bracket, and both the main unit base and the L-shaped bracket are provided with clearance openings for the counterweight guide rail to pass through.

[0019] To further enhance the overall structural strength of the counterweight system and reduce tilting or off-center loading issues, the system also includes vertically arranged car guide rails. These car guide rails are arranged in pairs and connected to the support frame as an integral structure, with the car guide rails and counterweight guide rails located on different sides of the support frame.

[0020] A further option is to install decorative sleeves on the car guide rails.

[0021] On the other hand, the present invention also provides an assembly method for an elevator counterweight system independent of the shaft sidewall, comprising the following steps:

[0022] S101. Prepare the counterweight guide rails and the support frame with vertical counterweight space;

[0023] S102. The counterweight guide rails are vertically arranged in pairs within the counterweight space;

[0024] S103. The counterweight guide rail and the support frame are connected as an integral structure;

[0025] S104. Fix the top of the support frame to the top of the elevator shaft and the bottom to the floor of the elevator shaft;

[0026] S105. A counterweight assembly is installed in the counterweight space, and the counterweight assembly is installed on the counterweight rail via a sliding device;

[0027] S106. The elevator main unit is fixedly installed at the top of the shaft;

[0028] S107. The counterweight assembly is configured to move up and down within the counterweight space along the counterweight guide rail under the drive of the elevator host.

[0029] The elevator counterweight system and its assembly method designed in this invention, which are independent of the shaft sidewall, utilize a modularly designed support frame and counterweight guide rail. This reduces reliance on specialized installation skills, simplifies the installation process, and improves construction efficiency. Furthermore, the system's independent structure minimizes the need for building modifications, freeing up shaft space and enhancing its aesthetic appeal and adaptability to civil engineering. In addition, compared to the wire rope guide system used in related technologies, the rigid guide rails of this invention exhibit superior structural stability and durability under continuous operation and high-intensity use, reducing maintenance requirements due to wear or loosening and effectively lowering long-term operating costs.

[0035] The components include: support frame 10, frame unit 11, first crossbeam 111, second crossbeam 112, corner bracket 113, positioning component 114, counterweight space 20, counterweight guide rail 30, rigid guide rail 31, main unit base 40, counterweight assembly 50, sliding device 51, ground fixing seat 60, top fixing seat 70, connecting plate 80, L-shaped bracket 90, clearance opening 91, car guide rail 100, and decorative sleeve 101. Detailed Implementation

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] Example 1.

[0038] like Figure 1-5 As shown, this embodiment provides an elevator counterweight system independent of the shaft sidewall, including: a support frame 10, the top of which is fixedly connected to the top of the elevator shaft and the bottom of which is fixedly connected to the ground of the elevator shaft, and the support frame 10 has a vertical counterweight space 20 inside;

[0039] Counterweight guide rails 30 are vertically arranged in pairs within the counterweight space 20 and are connected to the support frame 10 as an integral structure; elevator main unit;

[0040] The counterweight assembly 50 is located within the counterweight space 20 and is mounted on the counterweight guide rail 30 via a sliding device 51. It is configured to move up and down within the counterweight space 20 along the counterweight guide rail 30 under the drive of the elevator host.

[0041] In specific implementation, such as Figure 1 As shown, the top of the support frame 10 is fixedly connected to the top of the elevator shaft, and the bottom is fixedly connected to the ground of the elevator shaft, forming a stable support structure. Simultaneously, the support frame 10 has a vertical counterweight space 20 inside, providing installation space for the counterweight guide rail 30 and the counterweight assembly 50. (Refer to...) Figure 3 As shown, the counterweight assembly 50 is installed on the counterweight guide rail 30 via the sliding device 51 to ensure that it can slide freely on the guide rail. The elevator host is installed in the shaft. During operation, the elevator host starts and drives the counterweight assembly 50 to move up and down along the counterweight guide rail 30 to realize the lifting and lowering of the elevator car.

[0042] With this structural design, the entire counterweight system is independent of the building shaft sidewall, reducing dependence on the building itself. Compared with the wire rope guide system in related technologies, this integrated counterweight system has better durability, especially under continuous operation and high-intensity use conditions. It effectively reduces maintenance needs caused by wear or loosening, resulting in low long-term operating costs and effectively meeting the design and use requirements of home elevators.

[0043] Specifically, such as Figure 1 As shown, the support frame 10 includes multiple frame units 11, which are arranged vertically at intervals. Two or more adjacent frame units 11 are connected to each other as an integral structure through counterweight guide rails 30.

[0044] In this way, the frame unit 11 and the counterweight guide rail 30 are separate modular components. During construction, only one frame unit 11 needs to be fixed at the bottom of the shaft. Then, using the counterweight guide rail 30 as a connector, other frame units 11 can be assembled one by one in the shaft to build the entire support frame 10. There is no need to open holes in the side wall, which avoids complicated on-site processing, improves construction efficiency, and this modular construction method does not rely on the structural strength of the shaft wall, and has good civil engineering adaptability.

[0045] It is worth mentioning that in this design, the counterweight guide rail 30 not only serves as a counterweight guide, but also as a structural unit of the support frame 10. This integrated design makes the guide rail and the support frame structure reasonably integrated, making the overall structural layout more compact and stable, and effectively releasing and utilizing the valuable elevator shaft space, greatly improving the utilization rate of the shaft space.

[0046] In some embodiments, to enhance the overall aesthetics of the counterweight system, decorative panels (not shown) are provided on the outer walls of two or more adjacent frame units 11, with the edges of adjacent decorative panels fitting together.

[0047] The use of decorative panels, with their edges fitting together, creates a unified and continuous appearance. This effectively conceals the structure of the support frame 10, counterweight track 30, and counterweight assembly 50, allowing the entire counterweight system to blend seamlessly with the architectural decor, presenting a simple and coherent overall aesthetic effect. At the same time, the decorative panels act as a physical barrier, serving a decorative purpose while reducing the possibility of foreign objects entering the counterweight space 20 and interfering with the operation of the counterweight assembly 50. In addition, the decorative panels also have a certain sound insulation effect, helping to reduce the noise generated by the counterweight assembly 50 during operation.

[0048] In addition, in some examples, such as Figure 3 and Figure 4As shown, the counterweight guide rail 30 is fixed to the inner wall of the corresponding frame unit 11 by connectors (such as bolts and nuts), while the decorative panel is fixed to the outer wall of the frame unit 11 by positioning member 114. The decorative panel is preferably made of metal. Therefore, the decorative panel can work together with the counterweight guide rail 30 to further enhance the rigidity and stability of the entire counterweight system (support frame 10) structure.

[0049] In some embodiments, such as Figure 2 As shown, the frame unit 11 includes a first crossbeam 111 and a second crossbeam 112, which are connected by a detachable corner bracket 113 to form a rectangular frame structure.

[0050] In this embodiment, the first crossbeam 111, the second crossbeam 112, and the corner bracket 113 can be prefabricated separately. During construction, the bottom frame unit 11 is installed first, and the other units only need to be assembled in sequence. The construction mode is simple and efficient, and the modular components (111, 112, 113) are smaller in size, making transportation and storage more convenient and avoiding the difficulties in transportation and storage of large integrated components.

[0051] In some embodiments, such as Figure 2 and Figure 4 As shown, in order to reduce installation errors and improve installation stability, the following are also included:

[0052] The ground fixing base 60 is used to fix the bottom frame unit 11 (located at the very bottom of the entire support frame 10) to the ground of the elevator shaft;

[0053] The top mounting bracket 70 is used to fix the top (located at the very top of the entire support frame 10) frame unit 11 to the top of the elevator shaft.

[0054] In this embodiment, both the top fixing seat 70 and the ground fixing seat 60 are pre-fixed to the top and bottom of the elevator shaft using steel expansion bolts. On the one hand, this provides clear positioning for the subsequent assembly of the frame unit 11. On the other hand, if there are some uneven areas at the top and bottom of the shaft, the bottom and top fixing seats can provide a flat installation base for the frame unit 11 after installation. The subsequent assembly of the frame unit 11 on this base can minimize installation errors such as positional offset or tilt caused by building unevenness, ensuring the verticality and positional accuracy of the final support frame 10, and guaranteeing the installation quality of the counterweight system.

[0055] In some embodiments, such as Figure 1 and Figure 3As shown, in order to ensure the flatness of the guide rail connection, the counterweight guide rail 30 is assembled on the support frame 10 in sections by one section of rigid guide rail 31 or multiple sections of rigid guide rail 31 to form a continuous track structure; two vertically adjacent rigid guide rails 31 are connected end to end by a connecting plate 80. The connecting plate 80 and the rigid guide rail 31 are provided with fixing holes, and fasteners pass through the fixing holes to be fixedly connected to the connecting plate 80 and the rigid guide rail 31.

[0056] In this embodiment, the rigid guide rail 31 is assembled with the connecting plate 80 to form a continuous counterweight guide rail 30. The appropriate number of rigid guide rails 31 can be selected for on-site assembly according to the actual height of the shaft. This not only reduces the reliance on professional installation skills but also improves construction efficiency. At the same time, the connecting plate 80 can well connect the ends of the upper and lower rigid guide rails 31 and ensure a smooth transition on the surface of the counterweight guide rail 30 after the fasteners (such as bolts and nuts) are fixed, forming a continuous track structure and avoiding steps or gaps at the guide rail joints.

[0057] In some examples, it is understandable that for home elevators with low floor heights (such as villa elevators), the counterweight guide rail 30 may be composed of a single rigid guide rail 31.

[0058] In other examples, the rigid guide rail 31 has interlocking tenon structures on both ends to improve the overall torsional rigidity of the counterweight guide rail 30.

[0059] In some embodiments, such as Figure 2 As shown, in order to optimize space utilization, a main unit base 40 is also included. An L-shaped bracket 90 is fixedly installed on the counterweight guide rail 30. The L-shaped bracket 90 is located on the top side of the counterweight guide rail 30. The main unit base 40 is fixed on the L-shaped bracket 90. Both the main unit base 40 and the L-shaped bracket 90 are provided with clearance openings 91 for the counterweight guide rail 30 to pass through.

[0060] In specific implementation, such as Figure 2 As shown, the L-shaped bracket 90 is fixedly installed on one side of the top of the counterweight guide rail 30 by bolts, and the main unit base 40 is fixed on the L-shaped bracket 90. In this embodiment, the main unit base 40 is not only limited to installing the elevator main unit, but can also be used to install other components or equipment, such as the hardware required for the elevator control system. The clearance opening 91 allows the counterweight guide rail 30 to pass through, which utilizes the concentrated arrangement of the counterweight space 20, avoids the main unit base 40 occupying additional plane space, and improves the utilization rate of the counterweight space 20.

[0061] Of course, in some examples, the top of the building shaft is equipped with a machine room, where the main unit base 40 can be placed. This helps to reduce the load on the counterweight guide rail 30, that is, to reduce the structural pressure on the support frame 10, thereby improving the overall stability of the counterweight system.

[0062] In some embodiments, such as Figure 1 As shown, it also includes a vertically arranged car guide rail 100. The car guide rail 100 is arranged in pairs and connected to the support frame 10 to form an integral structure. The car guide rail 100 and the counterweight guide rail 30 are located on different sides of the support frame 10.

[0063] In this embodiment, the car guide rail 100 and the counterweight guide rail 30 have the same structure, that is, they are assembled in sections on the support frame 10 by one section of rigid guide rail 31 or multiple sections of rigid guide rail 31 to form a continuous track structure. With this structural design, the car guide rail 100 not only plays the role of guiding the car, but also serves as a structural unit of the support frame 10, so that the car guide rail and the support frame structure are reasonably integrated, further enhancing the overall load capacity of the counterweight system.

[0064] For example Figure 1 and Figure 5 As shown, in some examples, the opposite sides (non-counterweight guide rail fixed sides) of the support frame 10 are provided with a group of car guide rails 100, and the counterweight guide rails 30 are provided with two pairs of car guide rails 100 in the counterweight space 20. This arrangement meets the requirements of a double-car elevator, and the two cars are located on both sides of the support frame 10 and have independent counterweight components 50, which can reduce the problem of tilting or uneven loading of the counterweight system during operation.

[0065] Furthermore, in some examples, for two car guide rails 100 corresponding to the same car, the following can be used: Figure 5 The relative arrangement shown places them on both sides of the car. Another arrangement is to place the two car guide rails 100 corresponding to the same car side by side on the same side of the car, that is, on the side of the support frame 10 close to the car (the side not where the counterweight guide rail is fixed). For example, the frame unit 11 is a rectangular frame, and two car guide rails 100 are fixed on opposite sides of the rectangular frame, thereby further improving the structural strength of the support frame 10.

[0066] In some embodiments, such as Figure 2 As shown, a decorative sleeve 101 is fitted onto the car guide rail 100. In this way, the decorative sleeve 101 conceals the original metal guide rail structure, making the overall appearance more aesthetically pleasing. In this embodiment, the decorative sleeve 101 is preferably made of metal, giving it a certain structural strength. When fitted onto the car guide rail 100, it can further enhance the car guide rail 100's comprehensive mechanical properties, such as its resistance to pressure and bending.

[0067] On the other hand, this embodiment also provides an assembly method for an elevator counterweight system independent of the shaft sidewall, used for manufacturing Figure 1The elevator counterweight system shown includes, but is not limited to, the following steps:

[0068] S101. Prepare the counterweight guide rail 30 and the support frame 10 with the vertical counterweight space 20.

[0069] S102. The counterweight guide rails 30 are vertically arranged in pairs within the counterweight space 20.

[0070] In some embodiments, the counterweight guide rail 30 is assembled in sections on the support frame 10 by one or more rigid guide rail sections 31 to form a continuous track structure.

[0071] S103. The counterweight guide rail 30 and the support frame 10 are connected as an integral structure.

[0072] In some embodiments, the support frame 10 includes a plurality of frame units 11, which are connected by counterweight guide rails 30 as connectors to form the entire support frame 10.

[0073] S104. Fix the top of the support frame to the top of the elevator shaft and the bottom to the floor of the elevator shaft.

[0074] In some embodiments, during assembly, the first frame unit 11 can be installed at the bottom of the elevator shaft as a foundation, and then other frame units 11 can be sequentially connected to each other as an integral structure via rigid guide rails 31.

[0075] S105. A counterweight assembly 50 is installed in the counterweight space 20, and the counterweight assembly 50 is mounted on the counterweight rail 30 via a sliding device 51.

[0076] For example, the counterweight components 50 are hoisted into the counterweight space 20 piece by piece, and the counterweight components 50 are installed on the counterweight guide rail 30 using the sliding device 51. At the same time, the sliding of the counterweight components 50 on the guide rail 30 is checked to ensure smooth and unobstructed movement.

[0077] S106. Securely install the elevator main unit at the top of the shaft.

[0078] For example, the main unit base 40 is fixed at a pre-designed installation location (one side of the top of the shaft), and the elevator main unit and related control system are installed on the main unit base 40 to ensure a reasonable center of gravity.

[0079] S107. The counterweight assembly is configured to move up and down within the counterweight space along the counterweight guide rail under the drive of the elevator host.

[0080] For example, after the elevator main unit is installed in place and connected to the counterweight component 50, to ensure power transmission, the system is debugged, the operation of each component is checked, and after confirming that all parameters and safety measures are in place, it can be put into use.

[0081] The system is structurally stable, easy to install, does not require attachment to the sidewalls of the building shaft, has good adaptability to civil engineering, and has the advantage of low maintenance costs.

[0082] It should be noted that the order of the above assembly steps is not fixed or mandatory, but rather a preferred implementation method. In actual operation, the execution order of these steps can be reasonably adjusted according to specific circumstances, and some steps can be performed simultaneously. Assembly personnel can adapt to local conditions and arrange the most suitable process to complete the entire assembly process.

[0083] The elevator counterweight system and its assembly method, which are independent of the shaft sidewalls, provided in this embodiment, utilize a modularly designed support frame and counterweight guide rails. This reduces reliance on specialized installation skills, simplifies the installation process, and improves construction efficiency. Furthermore, the system's independent structure minimizes the need for building modifications, freeing up shaft space and enhancing its aesthetic appeal and adaptability to civil engineering. In addition, compared to the wire rope guide systems used in related technologies, the rigid guide rails of this invention exhibit superior structural stability and durability under continuous operation and high-intensity use, reducing maintenance requirements due to wear or loosening and effectively lowering long-term operating costs.
