Description

A modularly installed platform home elevator Technical Field

[0001] This invention belongs to the field of elevator equipment technology, specifically a modularly installed platform home elevator. Background Technology

[0002] Modularly installed platform home elevators are a modern and convenient home elevator solution. Their main feature is that they consist of multiple modules that can be assembled and installed within the home environment without the need for traditional large-scale construction. This type of elevator system can typically be installed within a few days, making the installation process simpler and more efficient than traditional elevators. Existing modular home elevators mostly use a single traction system to achieve elevator balance and movement, which lacks consideration for the capacity, stability, and maximum load capacity of the home's electrical system. Under special operating conditions (such as cargo transport), their failure rate is high, and the safety protection they provide is low. Therefore, it is necessary to provide a modularly installed platform home elevator to solve the problems mentioned in the background technology. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a modularly installed platform home elevator, comprising: a guide rail system configured as a shaft erected within a building; the guide rail system forming the elevator's motion frame; a car mechanism vertically and slidably mounted on one side of the guide rail system; a safety door on the car mechanism to ensure passenger safety; detachable and symmetrically arranged guardrails on both sides of the guide rail system; and a positioning frame fixedly installed at the building's ceiling; an electric drive system mounted on the positioning frame; the electric drive system connected to the car mechanism to provide lifting power; and a cable assembly assembly at the connection between the electric drive system and the car mechanism, used to fix or distribute the traction ropes connected to the car mechanism in the electric drive system, so that the car mechanism can perform combined rope or multi-rope traction lifting.

[0004] Furthermore, as a preferred embodiment, the electric drive system includes: an installation template fixed below the positioning frame, with multiple installation guide rails distributed circumferentially on the installation template, and a permanent magnet synchronous traction machine detachably installed on each of the installation guide rails, the output end of the permanent magnet synchronous traction machine being provided with a traction wheel for winding the traction rope; the multiple permanent magnet synchronous traction machines operate independently.

[0005] Furthermore, as a preferred embodiment, the wire harness assembly includes: an upper connecting plate, installed above the car mechanism, a shaft column fixed on the upper connecting plate, a positioning tube fixedly fitted onto the shaft column, and multiple lifting point displacement adjustment components corresponding to the permanent magnet synchronous traction machine in the electric drive system distributed on the upper end face of the upper connecting plate, and a wire harness device also provided in the positioning tube.

[0006] Furthermore, as a preferred embodiment, the lifting point displacement adjustment assembly includes: a sliding frame, which is laterally fixed on the upper connecting plate; a sliding rod is laterally fixed on one side of the sliding frame; a positioning block is slidably disposed on the sliding rod; and a threaded adjusting rod is rotatably disposed on the sliding frame; the positioning block is slidably connected to the threaded adjusting rod through threaded engagement.

[0007] Furthermore, preferably, the positioning block can be adjusted to the four corners of the car mechanism under synchronous sliding adjustment.

[0008] Furthermore, as a preferred embodiment, the cable harness includes: a bushing, coaxially slidably disposed within the positioning tube, the bushing having multiple harnessing holes, and a locking tube sleeved onto a section of the traction rope extending into the positioning tube, one end of each locking tube extending into the positioning tube, the bushing capable of vertically displacing each locking tube into the harnessing hole, a pin buckle slidably disposed laterally at each harnessing hole on the outside of the bushing, a support spring sleeved onto each pin buckle, and a positioning sleeve slidably disposed on the outside of the bushing, a ring frame embedded and fixed within the positioning sleeve, the ring frame abutting against one end of each pin buckle, and an adjusting ring rotatably disposed on the positioning sleeve, the adjusting ring being connected and driven to the bushing via threaded engagement.

One end of both the upper and lower tubes is fixedly sleeved on the traction rope, and the upper and lower tubes are disassembled and installed by threaded engagement. A tension spring is connected to the section of the traction rope that extends into the locking tube.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The electric drive system provided in this invention can be assembled with multiple permanent magnet synchronous traction machines according to the specific use situation. The multiple permanent magnet synchronous traction machine can perform single rope traction lifting through the wire assembly assembly, or it can be adjusted to perform multi-rope traction lifting, thereby providing corresponding load-bearing capacity and lifting speed.

[0020] Please refer to Figure 1. In this embodiment of the invention, a modularly installed platform home elevator includes: a guide rail system 1, configured as a shaft erected within a building, the guide rail system 1 forming the elevator's motion frame, and a car mechanism 12 vertically slidably mounted on one side of the guide rail system 1. The car mechanism 12 has a safety door and is typically made of steel or other robust materials to ensure passenger safety; removable and symmetrical guardrails 11 are detachably arranged on both sides of the guide rail system 1, and a positioning frame 13 is fixedly installed at the ceiling of the building. An electric drive system 3 is mounted on the positioning frame 13, and the electric drive system 3 is connected to the car mechanism 12 to provide the system's lifting power. The connection between the electric drive system 3 and the car mechanism 12... A cable harness assembly 2 is provided at the location. The cable harness assembly 2 is used to fix or disperse the traction ropes connected to the car mechanism 12 in the electric drive system 3, so that the car mechanism 12 can perform combined rope or multi-rope traction lifting. It also includes a control system (not shown in the figure). The control system is the brain of the elevator, responsible for monitoring the elevator's operating status, scheduling the elevator's operation, and ensuring passenger safety. The control system mainly includes user interface devices such as buttons, indicator lights, and safety sensors. Compared with the construction process of traditional elevators, the modular installation of the guide rail system, car mechanism, guardrail, electric drive system, and cable harness assembly can be completed faster. It uses prefabricated and pre-installed modules, reducing construction time and workload.

[0021] In this embodiment, the electric drive system 3 includes: an installation template fixed below the positioning frame 13, with multiple installation guide rails distributed circumferentially on the installation template, and a permanent magnet synchronous traction machine 31 detachably installed on each of the installation guide rails. The output end of the permanent magnet synchronous traction machine 31 is provided with a traction wheel 32 for winding the traction rope. The multiple permanent magnet synchronous traction machines 31 operate independently. Traditional elevators mostly use a single traction system, while this device can disassemble and install multiple permanent magnet synchronous traction machines as needed, thereby facilitating the provision of multi-rope traction and improving safety.

[0022] In a preferred embodiment, the wire harness assembly 2 includes: an upper connecting plate 22, installed above the car mechanism 12; a shaft column 23 fixed on the upper connecting plate 22; a positioning tube 21 externally fixed to the shaft column 23; and multiple lifting point displacement adjustment components 4 corresponding to the permanent magnet synchronous traction machines 31 in the electric drive system 3 distributed on the upper end face of the upper connecting plate 22. The positioning tube 21 also contains a wire harness device 5. Specifically, multiple permanent magnet synchronous traction machines are connected to the lifting point displacement adjustment components via multiple traction ropes passing through the wire harness device. The lifting point displacement adjustment components, in conjunction with the wire harness device, form a multi-rope traction or combined rope traction of the car mechanism, wherein:

[0023] Combined rope system: In this system structure, a relatively thick traction rope is combined with multiple traction sheaves to connect the car mechanism. Each traction sheave is responsible for tractioning a portion of the car mechanism's weight. Multiple permanent magnet synchronous traction machines can operate independently. By adjusting the speed of each permanent magnet synchronous traction machine, the weight distribution of the elevator is balanced. This system can provide high traction force and a large load-bearing capacity, making it suitable for high-rise buildings or occasions requiring the transport of a large number of people and goods.

[0024] Multi-rope traction system: In a multi-rope traction system, the car mechanism uses multiple thin traction ropes connected to several independent permanent magnet synchronous traction machines and traction sheaves. Each traction rope is independently responsible for tractioning a portion of the elevator's weight. The multi-rope traction system can achieve elevator balance and movement by controlling the tension and speed of each rope. This system is typically used in smaller elevators, such as those in the lower floors of residential buildings.

[0025] In this embodiment, the lifting point displacement adjustment 4 component includes: a sliding frame 41, which is laterally fixed on the upper connecting plate 22; a sliding rod 42 is laterally fixed on one side of the sliding frame 41; a positioning block 44 is slidably disposed on the sliding rod 42; and a threaded adjusting rod 43 is rotatably disposed on the sliding frame 41; the positioning block 44 is slidably connected to the threaded adjusting rod 43 through threaded engagement.

[0026] The effectiveness of the two systems depends primarily on the specific application scenario and requirements.

[0027] In this embodiment, the positioning block 44 can be adjusted to the four corners of the car mechanism 12 under synchronous sliding adjustment, thereby forming a multi-rope traction system.

[0028] In this embodiment, the wire harness device 5 includes: a bushing 51, coaxially slidably disposed within the positioning tube 21; the bushing 51 has multiple harnessing holes, and a locking tube 6 is sleeved on a section of the traction rope extending into the positioning tube 21; one end of each locking tube 6 extends into the positioning tube 21; the bushing 51 can extend each locking tube 6 into the harnessing hole under vertical displacement; a pin buckle 52 is laterally slidably disposed on the outside of the bushing 51 at each harnessing hole; a support spring is sleeved on the pin buckle 52; and the bushing 51... A positioning sleeve 54 is slidably sleeved on the outside. A ring frame 53 is embedded and fixed inside the positioning sleeve 54. The ring frame 53 abuts against one end of each of the pin buckles 52. An adjusting ring 55 is rotatably mounted on the positioning sleeve 54. The adjusting ring 55 is connected to the bushing 51 through threaded engagement. That is, the installation height of the positioning sleeve is manually adjusted. When the fixing hole is sleeved outside each locking tube, the adjusting ring drives the pin buckle to make radial displacement through the ring frame under threaded adjustment, so as to externally lock the locking tube, thereby realizing the connection of the rope.

[0029] In a preferred embodiment, the locking tube 6 is provided with a locking hole for the insertion and fixing of the pin buckle 52. The contact surface between the ring frame 53 and the pin buckle 52 is set as an inclined structure, thereby realizing the radial adjustment displacement of the pin buckle so as to adjust the combination rope system or multi-rope traction system according to the assembly requirements.

[0030] In this embodiment, the locking tube 6 is constructed as a two-section detachable structure, namely an upper tube 61 and a lower tube 62. One end of the upper tube 61 and the lower tube 62 are fixedly sleeved on the traction rope, and the upper tube 61 and the lower tube 62 are disassembled and installed by threaded engagement. The section of the traction rope that extends into the locking tube 6 is connected to a tension spring 63. Especially in use, the locking tube on one or more traction ropes is elastically stretched and pulled by the tension spring under the action of disassembly, so that the lifting and lowering work can be relatively advanced in the use of the car mechanism (relative to the rigid traction rope). That is, by correspondingly controlling the early winding work of the permanent magnet synchronous traction machine (especially in the descent, the permanent magnet synchronous traction machine also winds up in advance), a deceleration effect is formed in the lifting and lowering of the car mechanism, which has high safety. At the same time, the installation of the braking system is omitted, and the braking effect similar to that of the braking system is achieved, and the assembly is simpler.

[0031] Specifically, the assembly process only requires the installation of the necessary guide rail system, guardrails, car mechanism, cable assembly components, and electric drive system. The number of permanent magnet synchronous traction machines can be adjusted according to usage requirements. In particular, the cable assembly components can be used to adjust the rope system or multi-rope traction system, thereby improving assembly convenience and better meeting the needs of heavy-duty or high-rise high-speed elevators.

[0032] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
