Description

Technical Field

[0001] This invention relates to the elevator industry, and more specifically, to a detachable elevator traction machine and its installation method. Background Technology

[0002] Currently, traction machines on the market use a cast-in-place one-piece base. Due to the one-piece base, the assembly process of the traction machine is quite complex, requiring factory installation followed by overall transport. This presents a problem: since elevator installation sites are often tall buildings, installation is often limited by space constraints, requiring manual transport. The assembled traction machine is quite heavy, requiring multiple people to work together, and the limited width of staircases in buildings makes transport extremely difficult.

[0003] Chinese Patent Publication No. CN214652892U, entitled "An Encoder Mounting Structure for Elevator Traction Machines," discloses an encoder mounting structure for elevator traction machines, including a traction machine body, a non-contact encoder, a sensing shaft, and a transmission chain. The traction machine body includes a housing, a rotating shaft, a traction sheave, a rotor, a stator, a front bearing, and a rear bearing. An assembly cavity is provided within the housing. The front and rear bearings are respectively mounted on the front and rear side walls of the housing. The rotating shaft passes sequentially through the front bearing, the assembly cavity, and the rear bearing. The stator and rotor work together to drive the traction sheave and the rotating shaft to rotate synchronously. A third mounting hole is provided on the front side wall of the housing at a predetermined distance from the first mounting hole. This prior art is a typical traction machine structure with a cast-base base, requiring factory assembly, and on-site installation and handling are quite labor-intensive.

[0004] In summary, this application aims to realize a detachable elevator traction machine, which reduces the difficulty of disassembling and assembling the elevator traction machine, thereby allowing the components to be transported to the installation location for on-site assembly and reducing the number of people required for handling. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing cast-base traction machines, which are difficult to disassemble due to complex assembly processes. It provides a disassembleable elevator traction machine and its installation method, which is easier to disassemble and assemble, allowing the components to be transported to the installation location and then assembled on-site, reducing the number of people required for coordination during handling.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A detachable elevator traction machine includes a base, a rotating shaft, a traction sheave, a stator assembly, and a rotor assembly. The base includes a base body and a stator fixing seat detachably connected inside the base body. The base body includes a cylindrical body. The stator assembly is fixedly connected to the stator fixing seat, and the rotor assembly is rotatably connected to the stator fixing seat. The rotating shaft extends out of the base and is fixedly connected to the traction sheave.

[0008] In related technologies, the base needs to simultaneously perform both support and positioning functions, resulting in a complex structure. Furthermore, the mutual constraints between these two functions lead to a complex assembly process, requiring the traction machine to be shipped pre-assembled. This application decouples the base by dividing it into an external base body and an internal stator mounting base, which respectively perform the support and positioning functions. This allows the stator and rotor assemblies to be pre-installed on the stator mounting base to form the motor assembly, which is then separated from the base body. During on-site installation, each component can be transported to the installation location separately for on-site assembly, reducing the load per transport trip. The base body can be made of cast iron or sheet metal. In summary, this application allows the base body, traction sheave, and motor assembly with stator mounting base to be transported separately and assembled at the installation location, reducing the load per trip and minimizing the manpower required for each handling operation.

[0009] Preferably, the base body includes several base plates, each base plate including a front plate, a rear plate, and side plates forming a cylindrical body. The cylindrical body includes an upper plate, a lower plate, a left plate, and a right plate fixedly connected by welding. The front plate is welded to the cylindrical body, and the rear plate is detachably connected to the cylindrical body via fasteners. The base plates are plates of uniform wall thickness. Compared to related technologies, this application uses a non-cast base body. Specifically, by setting base plates, the annular side plates, front plate, and rear plate are fixedly connected by welding and riveting. The rear plate is detachably connected by fasteners. This type of base body is more environmentally friendly and lighter than the casting process used in related technologies. The detachable rear plate allows for modular installation of the stator and rotor assemblies, facilitating installation and maintenance. The stator and rotor assemblies are installed from the rear of the base body, further reducing the difficulty of disassembly and assembly.

[0010] Preferably, the cross-section of the cylinder is rectangular, and the cylinder includes an upper plate, a lower plate, a left plate, and a right plate that are fixedly connected by welding. The cylinder structure formed by welding has high strength, is simple to process, and has low cost.

[0011] Preferably, the stator mounting base includes a first ring and a second ring coaxially arranged, connected by reinforcing ribs. The first ring is located inside the second ring, and the interior of the first ring is used to allow and restrict the axial movement of the rotating shaft, while the second ring is used to fix the stator assembly. Compared with the base in related technologies, the stator mounting base has the advantages of smaller size and simpler manufacturing process.

[0012] Preferably, the rotor assembly includes a rotor body, with a plurality of fan blades fixedly connected to the side of the rotor body near the rear plate. The fan blades are arranged radially along the shaft, and the base body has openings for ventilation. In related technologies, the rotor body lacks a foundation for mounting fan blades, making it impossible to form an air duct inside the traction machine. In this application, by mounting fan blades on the side near the rear plate, they rotate synchronously with the rotor components, generating airflow to cool the stator and rotor assemblies, thereby improving the reliability of the elevator traction machine.

[0013] Preferably, a brake is fixedly connected to the side plate.

[0014] Preferably, the front panel has a first opening, and around the first opening, several fasteners are connected to the front panel, which are used to securely connect the stator mounting base. Connecting the front panel and the stator mounting base with fasteners is a simple and convenient method of connection and disassembly.

[0015] Preferably, the rear plate is provided with a second opening coaxial with the rotating shaft, and an encoder is fixedly connected to the second opening, with the rotating shaft of the encoder fixedly connected to the rotating shaft.

[0016] A method for installing a detachable elevator traction machine, comprising the detachable elevator traction machine as described above, including the following steps:

[0017] S1. Assemble the cylinder, shaft, stator mounting base, stator assembly, and rotor assembly together;

[0018] S2. Install the encoder on the rear panel;

[0019] S3. Install the rear plate onto the side plate to connect the encoder to the shaft;

[0020] S4. Install the traction sheave on the shaft;

[0021] S5. Install a brake on the cylinder.

[0022] Steps S2 to S4 are executed sequentially, while the order of steps S2 and S5 can be reversed.

[0023] The modular stator and rotor assemblies are connected to the housing and stator mounting base respectively to form the motor unit. The assembly process is simple and disassembly is convenient. During installation, the stator, rotor, and stator mounting bases are all inserted from the side of the housing closest to the rear plate, while the traction sheave is inserted from the side furthest from the rear plate. This eliminates the need for additional installation steps to avoid obstructing components, simplifying the installation structure and reducing the difficulty of assembly and disassembly.

[0024] Preferably, step S1 includes:

[0025] a. Insert the stator mounting bracket into the front plate and secure the stator mounting bracket to the cylinder body using fasteners;

[0026] b. Install the stator assembly onto the stator mounting base;

[0027] c. Securely connect the rotor assembly to the shaft;

[0028] d. Rotate the rotor assembly and shaft onto the stator mounting base.

[0029] The above steps are performed sequentially to install the components onto the cylinder, which is suitable for complete machine shipment.

[0030] Preferably, step S1 includes:

[0031] a. Install the stator assembly onto the stator mounting base;

[0032] b. Securely connect the rotor assembly to the shaft;

[0033] c. Rotarily mount the rotor assembly and shaft onto the stator mounting base;

[0034] d. The motor unit, consisting of the stator assembly, rotor assembly, and stator mounting base, is mounted on the front plate, and the stator mounting base is fixedly connected to the cylinder using fasteners.

[0035] The above steps mount the rotor assembly and stator assembly onto the stator mounting base to form a motor unit, which is suitable for batch transportation and on-site installation.

[0036] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting a box-type base body and a detachable rear plate on it, the complexity of the assembly process is reduced, and the possibility of disassembly, transportation, on-site installation, disassembly and maintenance is provided; (2) The installation form of the base body plus the stator fixing seat makes the elevator traction machine support the addition of auxiliary components such as fan blades, which improves the scalability of the elevator traction machine; (3) By splitting the base into a split base body and a stator fixing seat for positioning motor assembly, the whole machine of the traction machine is easier to disassemble and transport.

[0051] Example:

[0052] A detachable elevator traction machine, such as Figure 2 As shown, it includes a base, a rotating shaft 16, a traction sheave 26, a stator assembly 12, and a rotor assembly 15.

[0053] The stator assembly 12 and the rotor assembly 15 constitute a motor unit. The stator assembly 12 includes a stator core 13 with windings, and the rotor assembly 15 includes a rotor body 20 and magnets 21 attached to the rotor.

[0054] When energized, the rotor assembly 15 and the stator assembly 12 rotate relative to each other under the influence of electromagnetic force. The stator assembly 12 and the rotor assembly 15 constitute a typical electric motor. The principle of an electric motor is common knowledge in the field and will not be described in detail here.

[0055] The shaft 16 and the traction sheave 26 rotate together and are connected by a key.

[0056] The stator assembly 12 is fixedly connected to the base, and the rotor assembly 15 rotates relative to the stator assembly 12 and the chassis. The rotation of the shaft 16 drives the traction sheave 26 to rotate, thereby realizing the traction function of the elevator traction machine.

[0057] like Figure 1 , 2As shown, the base body includes a box 4 made of substrates. In other embodiments, the base body is a cast, integral structure. The box 4 includes a front plate 1, a rear plate 2, and several side plates 3. The sides of adjacent side plates 3 are fixedly connected to form a cylindrical body 5 open at both ends. In some embodiments, the cross-section of the cylindrical body 5 is polygonal; in other possible embodiments, the cross-section of the cylindrical body 5 is circular or elliptical. This application uses a rectangular cross-section as an example. The side plates 3 include four substrates. Two non-adjacent substrates have the same shape, and adjacent substrates have the same included angle. The cylindrical body 5 is fixedly connected to the front plate 1 in a non-detachable manner and to the rear plate 2 in a detachable manner. Specifically, the cylindrical body 5 is welded to the front plate 1, and the cylindrical body 5 is detachably connected to the rear plate 2 by screws. The screws pass through the rear plate 2 and the cylindrical body 5 sequentially along the direction from the front plate 1 to the rear plate 2, fixing the rear plate 2 and the cylindrical body 5 together. The front plate 1 has a first opening 6 at its center, and the rear plate 2 has a second opening 7 at its center. The first opening 6 and the second opening 7 are concentric and coaxial. A rope-stopping rod extending along the normal direction of the front plate 1 is fixedly connected to the front plate 1. The configuration of the rope-stopping rod is common knowledge in the art and will not be described in detail here. The substrate can be formed from rolled steel, wherein each substrate is not produced by casting, thus reducing weight and material costs. On a plane perpendicular to the direction from the front plate 1 to the rear plate 2, the minimum distance from the projection of the cylinder 5 to the axis of the first opening 6 is slightly greater than the radius of the rotor assembly 15. The substrate material is Q235 or other materials with sufficient strength.

[0058] like Figure 7 As shown, the base also includes a stator mounting base 8. The stator mounting base 8 is used to position the stator assembly 12 and the rotor assembly 15. The stator mounting base 8 is fixedly connected to the front plate 1. The stator mounting base 8 includes a first ring body 9 and a second ring body 10, which are concentrically arranged cylindrical bodies 5. Several reinforcing ribs 11 are provided between the first ring body 9 and the second ring body 10, and the reinforcing ribs 11 are arranged along the radial direction of the first ring body 9 and the second ring body 10. The front plate 1 has a first opening 6, and the stator mounting base 8 has an annular step that conforms to the first opening 6. The step fits against the inner wall of the first opening 6, restricting the circumferential movement of the stator mounting base 8. Along the central axis of the stator mounting base 8, several holes are provided at corresponding positions on the stator mounting base 8 and the front plate 1. Fasteners pass through the front plate 1 and the stator mounting base 8 in sequence, and the front plate 1 and the stator mounting base 8 are fixedly connected together. Along the direction from the front plate 1 to the rear plate 2, the cross-section of the first ring 9 of the stator fixing seat 8 gradually increases.

[0059] like Figure 2As shown, the stator assembly 12 includes a stator core 13 and a winding 14. The winding 14 is made of copper. The stator core 13 is annular, and its inner diameter is adapted to the diameter of the end of the stator mounting base 8 away from the front plate 1. The stator core 13 and the stator mounting base 8 are interference-fitted. The structure of the stator assembly 12 is the same as that of the stator assembly 12 in the prior art, and will not be described in detail here.

[0060] like Figures 2 to 6As shown, the rotor assembly 15 includes a front bearing, a rear bearing, a rotor body 20, and a magnet 21 fixedly connected to the rotor body 20. A rotating shaft 16 is arranged axially along the cylinder 5, with one end near the front plate 1 extending out of the first opening 6. The rotating shaft 16 passes through the first ring 9 of the stator mounting base 8; specifically, the rotating shaft 16 is coaxially arranged with the stator mounting base 8. Both ends of the rotating shaft are limited by the rotor body and the front bearing, respectively. Bearings are disposed between the rotating shaft 16 and the stator mounting base 8. Along the axial direction of the stator mounting base 8, the stator mounting base 8 has a front self-aligning roller bearing and a rear support deep groove ball bearing. The rotating shaft 16 is rotatably connected to the stator mounting base 8 via the bearings. The rotor body 20 is connected to the rotating shaft 16, wherein the rotor body 20 is keyed to the rotating shaft 16. The rotor body 20 is located between the rear plate 2 and the stator mounting base 8. In some possible embodiments, the rotor body 20 is mounted on the shaft 16, and the bearing near the rear plate 2 is located between the stator mounting base 8 and the rotor body 20. The rotor body 20 has an opening in its center for inserting the shaft 16. The rear bearing is limited by the stator mounting base 8 and the bearing cover, which is fixedly connected to the stator mounting base 8 by fasteners. The bearing end cap 19 and the stator mounting base 8 limit the outer ring of the rear bearing 18. A retaining ring is fixedly connected to the rotor body 20, and the rotor body 20 has a step. The step and the retaining ring limit the inner ring of the rear bearing 18. This limits the axial direction of the rotor assembly. The axial thickness of the rotor body 20 gradually decreases along the radial direction. The outer edge of the rotor body 20 has a protruding flange that extends towards the front plate 1. The distance from the flange to the axis of the shaft 16 is greater than the outer diameter of the stator assembly 12, thus avoiding interference. A magnet 21 is fixedly connected to the flange, wherein the magnet 21 is a sheet, and the material of the magnet 21 is neodymium magnet. Specifically, the magnet 21 is fixedly connected to the flange by adhesive. In some embodiments, a gear ring 22 is fixedly connected to the side of the rotor body 20 near the rear plate 2 by fasteners. The base body has an opening, and in an emergency, an emergency device is inserted through the opening, so that the gear of the emergency structure meshes with the device, driving the rotor assembly to rotate. In some possible embodiments, a fan blade 23 is fixedly connected to the side of the rotor body 20 near the rear plate 2 by fasteners. The fan blade 23 generates a pressure difference in the axial direction of the shaft 16 as the rotor assembly 15 rotates, forming an airflow to cool the motor unit. Possibly, several openings or slots are formed on the rear plate 2 for exchanging gas with the external environment. In some embodiments, a counterweight is detachably connected to the stator assembly 12 to improve the dynamic balance of the stator assembly 12 during rotation. The rotor body is fixedly connected to the shaft 16 by a cover plate by fasteners.

[0061] The rear plate 2 has a second opening 7, which is coaxial with the first opening 6 and the rotating shaft 16. An encoder 24 is fixedly connected to the rear plate 2. Around the second opening 7, the rear plate 2 has several openings through which an encoder mounting base 25 is fixedly connected to the rear plate 2 via fasteners. Then, along the direction from the front plate 1 to the rear plate 2, the encoder 24 is placed into the encoder mounting base 25, preventing it from moving along the direction from the front plate 1 to the rear plate 2 and from rotating relative to the base body. Then, the rotating end of the encoder 24 is inserted into the rotating shaft 16, causing the rotating end of the encoder 24 to move with the rotating shaft 16. Specifically, the distance from the outer edge of the rotating end of the encoder 24 to its axis is not uniform, and the end of the rotating shaft 16 away from the front plate 1 has an opening with a shape adapted to the rotating end of the encoder 24. In this way, the encoder 24 can record the rotation angle of the rotating shaft 16.

[0062] like Figure 1 As shown, the traction sheave 26 is fitted onto the portion of the rotating shaft 16 extending from the front plate 1, and is connected to the traction sheave 26 via a key to achieve synchronous rotation. The traction sheave 26 is fixedly connected to the rotating shaft 16 via a pressure plate 27. In the axial direction of the rotating shaft 16, the rotating shaft 16 has several openings on its end face near the traction sheave 26. The pressure plate 27 is fixedly connected to the end of the rotating shaft 16 by fasteners, pressing the traction sheave 26 onto the rotating shaft 16. Specifically, the fasteners pass through the pressure plate 27 and are threadedly connected to the rotating shaft 16.

[0063] The stator assembly 12 is fixedly connected to the base. The rotor assembly 15 is provided with a rotating shaft 16. Along the axial direction of the rotating shaft 16, the rotor assembly 15 is rotatably connected to the base. The base includes a base body, which includes several base plates. Each base plate is a plate with equal wall thickness. Adjacent base plates are fixedly connected. Each base plate includes a side plate 3 and a rear plate 2 forming an annulus. The rear plate 2 is detachably connected to the side plate 3 by fasteners.

[0064] like Figure 1 , 2 As shown, the detachable elevator traction machine also includes a brake 28. The structure of the brake 28 is prior art and will not be described in detail here. An opening is provided on the side plate 3, through which the braking function structure of the brake 28 extends into the base body to achieve the braking function. In this embodiment, there are specifically two brakes 28. The brakes 28 are symmetrically arranged on both sides of the base body. The brakes 28 are fixedly connected to the base body by fasteners, and the brakes 28 are located on the outside of the base body.

[0065] like Figure 2 As shown, based on the aforementioned detachable elevator traction machine, this application also proposes an installation method for a detachable traction machine that differs from the prior art. In one embodiment, the steps include:

[0066] S1. Insert the stator fixing seat into the cylinder and fix the stator fixing seat to the cylinder with fasteners;

[0067] S2. Install the stator assembly onto the stator mounting base;

[0068] S3. Securely connect the rotor assembly to the rotating shaft;

[0071] S6. Install the rear plate onto the side plate to connect the encoder to the shaft;

[0072] S7. A traction sheave is installed on the shaft;

[0073] S8. Install the brake on the base.

[0074] Steps S5 to S7 are executed sequentially, while the order of steps S5 and S8 can be reversed.

[0075] In another possible embodiment, the steps include:

[0076] S1. Install the stator assembly onto the stator mounting base;

[0077] S2. Securely connect the rotor assembly to the rotating shaft;

[0078] S3. Rotate the rotor assembly and shaft onto the stator mounting base;

[0079] S4. The motor unit formed by the stator assembly, rotor assembly and stator mounting base is mounted on the front plate, and the stator mounting base is fixedly connected to the cylinder by fasteners.

[0080] S5. Install the encoder on the rear panel;

[0081] S6. Install the rear plate onto the side plate to connect the encoder to the shaft;

[0082] S7. A traction sheave is installed on the shaft;

[0083] S8. Install a brake on the cylinder.

[0084] Steps S5 to S7 are executed sequentially, while the order of steps S5 and S8 can be reversed.

[0085] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
