Description

Technical Field

[0001] This utility model relates to the field of elevator layout technology, specifically to a novel rear-mounted layout for a home sightseeing elevator with an aluminum alloy frame shaft. Background Technology

[0002] In the scenario of retrofitting home sightseeing elevators, traditional elevators generally face the problems of difficult space adaptation and high installation costs: traditional shafts mostly rely on steel structure welding or concrete pouring, the construction process is complicated, and a special pit with a depth of more than 300mm needs to be excavated separately. The height requirement for the top floor is also mostly more than 3000mm, making it difficult to retrofit in narrow shafts, low top floors or existing buildings (such as duplexes and old villas); at the same time, the elevator and shaft need to be designed and constructed separately, the coordination cost is high, and it cannot meet the aesthetic requirements of home scenarios.

[0003] The existing announcement number CN212639619U, "A Layout Structure for a Rear Counterweight Elevator," solves the problem of narrow shaft width occupation and reduces the height of the top floor by placing the counterweight blocks on the rear side of the shaft and distributing the main beams on both sides of the top of the shaft. However, it still has obvious limitations: the shaft needs to be fixed by multiple main beams, which does not break through the traditional shaft construction mode and cannot eliminate the step of building a separate pit; moreover, it uses wire rope transmission and traditional mechanical switches, which is not compatible with the glass curtain wall design of home sightseeing elevators and cannot achieve one-stop installation of the elevator and shaft. It still cannot meet the convenience and aesthetic requirements of retrofitting existing buildings.

[0004] In summary, none of the existing technical solutions can fully meet the installation requirements of home sightseeing elevators: traditional elevator shaft construction is complex and requires a lot of space; although the above patents have optimized the layout of the counterweight and main beam, they have not solved the problems of pit construction, shaft construction simplification and sightseeing aesthetics, and none of them can meet the needs of space adaptation, convenient installation and home scenarios. Utility Model Content

[0005] This utility model aims to provide a novel rear-mounted layout for a home sightseeing elevator with an aluminum alloy frame shaft, in order to solve the technical problems of traditional home sightseeing elevators requiring separate construction of a deep pit, complex shaft construction, and high requirements for the top floor height when retrofitting.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel aluminum alloy frame shaft home sightseeing elevator with a rear-mounted layout, comprising an installation space running through all floors served by the elevator, an aluminum alloy frame shaft, a glass curtain wall, a main unit, car guide rails, counterweight guide rails, counterweight anti-rope sheave, anti-rope sheave, shaft anti-rope sheave, car top sheave, steel belt, car, car buffer, and a signal transmission system; the aluminum alloy frame shaft is composed of multiple aluminum alloy frame sections, which are bolted together on-site; the glass curtain wall is connected to the aluminum alloy frame through a special fixing structure to form a closed shaft; the main unit is fixedly installed in the rear area at the top of the shaft, and the main unit is positioned and installed through the car guide rails and counterweight guide rails. The elevator shaft is arranged along the height of the hoistway with the counterweight guide rail. One end of the steel belt is wound around the traction sheave of the main unit and connected to the counterweight anti-rope sheave, then extends and is fixed to the counterweight rope head. The other end of the steel belt is wound around the traction sheave of the main unit and connected in sequence to the anti-rope sheave, the hoistway anti-rope sheave, and the car top sheave, then extends and is fixed to the car rope head. The car moves up and down along the hoistway through the transmission of the steel belt. The car bottom adopts a thin structure design, and the car buffer adopts a low-height structure design. The car buffer is arranged below the car bottom, so that the height of the hoistway pit is adapted to the decoration height of the installation site, and there is no need to build a special pit separately. The signal transmission system uses a non-contact positioning method to transmit the elevator position signal in real time, and there is no need to set up traditional leveling switches and terminal switches.

[0007] The principle of this solution is as follows: First, multiple aluminum alloy frames are assembled on-site using bolts to form an aluminum alloy frame shaft. Then, a special fixing structure is used to connect the glass curtain wall to the aluminum alloy frame to form a closed shaft. The main unit is fixed at the top rear of the shaft and positioned by the car guide rail and the counterweight guide rail. When the main unit drives the traction sheave to rotate, one end of the steel belt wraps around the traction sheave and is fixed to the counterweight rope head via the counterweight anti-rope sheave. The other end wraps around the traction sheave and is fixed to the car rope head via the anti-rope sheave, the shaft anti-rope sheave, and the car top sheave. This drives the car to move up and down along the car guide rail. At the same time, the thin car bottom and the low-height car buffer make the shaft pit adaptable to the decoration height of the installation site, eliminating the need to build a separate pit. The non-contact positioning signal transmission system transmits the elevator position signal in real time, eliminating the need for traditional leveling and terminal switches.

[0008] Advantages of this solution: The aluminum alloy frame is assembled on-site with bolts and combined with a glass curtain wall to form a closed shaft, eliminating the need for traditional welding or pouring, thus simplifying shaft construction; The main unit is rear-mounted and positioned using guide rails, combined with steel belt drive to achieve stable car operation; The thin car bottom and low-height buffer allow the pit to adapt to the decoration height, eliminating the need for dedicated pit excavation; Non-contact signal transmission eliminates the need for traditional switches, improving signal transmission stability, and the overall solution is suitable for installation needs in space-constrained locations.

[0009] Preferably, as an improvement, the thickness of the thin structure of the car bottom is in the range of 40mm-60mm, the height of the low-height structure of the car buffer is in the range of 20mm-40mm, and the height of the shaft pit is adapted to the decoration height of the installation site, specifically in the range of 80mm-120mm.

[0010] Preferably, as an improvement, the outer surface color of the aluminum alloy frame and the color of the glass curtain wall can be customized according to the decoration style of the installation site. The glass curtain wall uses tempered glass with a thickness of 6mm-10mm, the cross-sectional dimensions of the aluminum alloy frame range from 70mm×70mm to 90mm×90mm, and the special fixing structure for connecting the glass curtain wall and the aluminum alloy frame is a stainless steel buckle.

[0011] Preferably, as an improvement, the car door opening method includes any one of center-opening, side-opening, and swing-opening. When the shaft width is 800mm-1000mm, the side-opening door method can be selected, with an opening width of 500mm-700mm.

[0012] Preferably, as an improvement, the counterweight anti-rope sheave is fixedly installed on the top of the counterweight, the anti-rope sheave and the hoistway anti-rope sheave are respectively installed in the top areas of different floors of the hoistway, and the car top sheave is installed on the top of the car; the diameter of the traction sheave is in the range of 300mm-400mm, the diameter of the counterweight anti-rope sheave and the car top sheave is in the range of 180mm-220mm, and the diameter of the anti-rope sheave and the hoistway anti-rope sheave is in the range of 160mm-200mm.

[0013] Preferably, as an improvement, the verticality deviation of the shaft after the aluminum alloy frame is assembled is ≤1‰; the elevator body is fixed to the aluminum alloy frame by a special bracket, and the special bracket is connected to the aluminum alloy frame by T-bolts. Limiting the verticality deviation of the assembled aluminum alloy frame and the fixing method of the elevator body ensures the accuracy and stability of the shaft structure, avoiding any impact on the safety and stability of elevator operation due to installation deviations.

[0015] The reference numerals in the accompanying drawings include: aluminum alloy frame 1, aluminum alloy frame column 101, aluminum alloy frame beam 102, traction sheave 2, anti-rope sheave 3, anti-rope sheave 4, car top sheave 5, car frame 6, car 7, car guide rail 701, car buffer 8, car bottom 9, counterweight device 10, counterweight guide rail 1001, and glass curtain wall 11. Detailed Implementation

[0016] The following detailed description illustrates the specific implementation method: This specific implementation method takes a three-story villa as an example. Each of the three floors of the villa is 3 meters high. The shaft is designed to be 900mm wide and 1800mm deep. The pit utilizes the existing 100mm of the installation space's interior decoration height, eliminating the need for separate construction. The basic configuration is as shown in the attached diagram. Figure 1 - Appendix Figure 2 As shown: A novel aluminum alloy frame shaft layout for home sightseeing elevators with a rear-mounted design is presented. The aluminum alloy frame shaft 1 is composed of multiple prefabricated aluminum alloy profiles with a cross-section of 70mm × 70mm. Each profile section has pre-drilled bolt holes on its end face, allowing for detachable and fixed connections via M10 bolts. After assembly, the overall verticality deviation is controlled within 1‰. The glass curtain wall 11 uses 8mm thick tempered glass and is connected to the aluminum alloy frame 1 via stainless steel clips. One end of the stainless steel clip is locked to the side groove of the aluminum alloy frame 1 by a T-screw, while the other end is clamped to the edge of the glass curtain wall 11 by anti-slip pads. Weather-resistant sealant is filled at the glass joints to form a sealed shaft. The outer surface of the aluminum alloy frame 1 is coated with a light gray coating to match the villa's interior design style.

[0017] The main unit is installed at the top rear of the hoistway. The traction sheave 2 of the main unit has a diameter of 350mm and is positioned and connected to the car guide rail 701 and counterweight guide rail 1001 via L-shaped angle steel brackets. The car guide rail 701 is of type T75, and the counterweight guide rail 1001 is of type T70. Both are arranged vertically along the height of the hoistway, with a total height of 9m. The side walls of the guide rails are fixed to the inner side of the aluminum alloy frame 1 of the hoistway with bolts. One end of the L-shaped angle steel bracket is locked to the screw hole of the main unit base with bolts, and the other end is fixed to the top end face of the car guide rail 701 and the counterweight guide rail 1001 by welding, forming an integrated positioning structure of the main unit and the guide rails. This ensures that the car 7 can exceed the main unit base by 150mm when running, ultimately controlling the minimum top floor height of the elevator to 2650mm.

[0018] The transmission system uses a 10mm wide steel belt, equipped with a 200mm diameter counterweight anti-rope pulley 4 and a car top pulley 5, as well as a 180mm diameter anti-rope pulley 3 and a hoistway anti-rope pulley 4. The counterweight anti-rope pulley 4 is fixed to the top of the counterweight device 10 via a bearing seat, and the bearing seat and the top plate of the counterweight device 10 are detachably connected by bolts; the anti-rope pulley 3 is fixed to the aluminum alloy frame 1 at the top of the hoistway 1 via a U-shaped bracket, and the hoistway anti-rope pulley 4 is fixed to the corresponding position at the top of the hoistway 3 via a U-shaped bracket of the same specification, and the brackets are all locked to the aluminum alloy frame 1 by T-bolts; the car top pulley 5 is fixed to the top end face of the car 7 via a bearing seat, and the bearing seat is welded to the top plate of the car 7. After one end of the steel belt is wound around the traction sheave 2 of the main unit, it fits against the outer circumferential groove of the counterweight anti-rope sheave 4, and the end is fixed to the counterweight rope head on the top of the counterweight device by a rope clamp; after the other end of the steel belt is wound around the traction sheave 2, it passes through the outer circumferential groove of the anti-rope sheave 3, the shaft anti-rope sheave 4, and the car top sheave 5 in sequence, and the end is fixed to the car 7 rope head on the top of the car 7 by a rope clamp, forming a complete closed-loop transmission structure.

[0019] The car frame 6 serves as the load-bearing frame for the car 7, located outside the car 7 within the hoistway. Its top is connected to the car top wheel 5 via a bearing seat. The four sides of the car frame 6 are bolted to the side walls of the car 7, completely enclosing and supporting the car 7. Supported by the car frame 6, the car 7 moves smoothly up and down along the car guide rail 701 via a steel belt drive that works in conjunction with the traction sheave 2 and the car top wheel 5. The car bottom 9 of the car 7 is made of 50mm thick steel plate. Flanges are pre-set on the edges of the car bottom 9, which are bolted to the flanges at the bottom of the side walls of the car 7, forming an integral car 7 structure. The car buffer 8 is made of polyurethane, with a height of 30mm. It is bolted to the area directly below the car bottom 9 on the hoistway floor. A 5mm gap is left between the top of the buffer and the bottom of the car bottom 9 to ensure flexible contact when the car 7 descends to the lowest floor, preventing damage from rigid collisions.

[0020] The signal transmission system uses a laser positioning module. The laser transmitter is fixed to the top of the car 7 near the door operator via an L-shaped bracket. The bracket is bolted to the top plate of the car 7. The power and signal lines of the transmitter are run through the cable trays inside the car 7 and connected to the PLC control system of the car 7. Signal receiving modules are bolted to the inner side of the aluminum alloy frame 1 at each floor of the hoistway. The signal lines of the receiving modules are run through the cable trays inside the hoistway and connected to the main control system. This eliminates the need for traditional leveling switches and terminal switches, as the car 7's position data is transmitted in real time via laser signals, ensuring that leveling accuracy is controlled within a reasonable range.

[0021] Because the shaft width is 900mm, a side-opening door operator is selected, with an opening width of 600mm. The door operator guide rail is fixed to the mounting beam on the side of the car 7 with bolts. The power and control lines of the door operator drive motor are connected to the control system of the car 7. The guide wheel on the corresponding side of the shaft is fixed to the aluminum alloy frame 1 shaft with a small bracket. The bracket is locked to the frame with T-bolts to ensure that the door can slide smoothly along the guide rail during the operation of the door operator without jamming or deviation.
