Description
Technical Field
[0001] The invention belongs to the technical field of elevators, and specifically refers to an aerial suspended monorail corridor elevator which can directly reach the entire corridor. Background Art
[0002] Many old multi-story residential buildings have a short staircase structure with a rest platform in the middle, that is, a combined staircase consisting of two groups of 8 steps. If an external vertical lift is to be installed, due to the limitations of the building structure, only a half-floor entry structure can be adopted, and the entrance and exit of the elevator door is set on the rest platform in the middle. Since it is not possible to enter the house on the same floor, the last 8 steps will bring additional burden and physical exertion to the elderly. For the elderly and physically disabled people who have difficulty in moving and need to ride in wheelchairs, it is an insurmountable obstacle, and truly barrier-free access throughout the entire journey cannot be achieved.
[0003] Installing an external elevator shaft outside the building and entering the entrance platform through a corridor bridge on each floor is a relatively ideal and adequate solution. However, the construction of the external elevator shaft requires digging a very deep pit, and a large elevator entrance and exit needs to be excavated on the gable (load-bearing wall) of each floor of the building. This will cause damage to the overall structural strength and potential safety hazards to old houses that have been in disrepair for many years. It will also have a series of negative impacts in terms of lighting, ventilation, noise, and the need to occupy the green belt outside the red line. In addition, it requires high engineering costs, which makes it unbearable for the majority of owners and difficult to reach a consensus on adding elevators. Therefore, progress is slow, the actual rate of adding elevators is very low, and it is difficult to promote and popularize it on a large scale. Summary of the invention

[0037] like Figures 1 to 18 As shown, the aerial suspended monorail corridor elevator proposed in this scheme which can reach the entire corridor directly includes a guide rail, a slide, a transmission system, a car, a hanger and a control system.

[0038] like Figures 3 to 6 As shown, the guide rails include linear guide rails and arc guide rails.

The sub-beam is welded and arranged below the main beam. The main beam adopts H-shaped steel. The sub-beam has rows of holes symmetrically arranged on both sides. Pins and rollers are arranged in the rows of holes. The pins and rollers are fixed with hexagonal nuts and flat washers with anti-loosening.

A connecting plate is also provided at the flange of the upper part of the main beam. The connecting plate is used to connect two main beams or bent plates, and is also used for the overall installation of the linear guide rails and the arc guide rails. The connecting plate can move arbitrarily along the main beam or the bent plate.
[0041] like Figure 9-10As shown, the slide is arranged on one side of the linear guide rail and the arc guide rail, and the slide moves up and down along the linear guide rail and the arc guide rail. The slide includes left and right side plates, pulleys and sprockets.

The left and right side plates are connected to the pulleys by fasteners, and the sprockets are arranged on the inner sides of the left and right side plates and are rotatably arranged under the linear guide rail, and the sprockets are engaged with rollers.
[0042] like Figure 9-10 As shown, the transmission system is arranged in a linear guide rail and an arc guide rail, the transmission system adopts a sprocket chain transmission pair, the transmission system is driven by a worm gear reduction box, the pulley, sprocket and roller constitute the transmission system, and the output shaft of the worm gear reduction box is connected to the sprocket.
[0043] like Fig.11 As shown, the suspension rod includes a bracket, a middle joint, an adjusting rod, a round tube and a pipe joint. The bracket and the pipe joint are symmetrically welded at both ends of the round tube. The middle joint is arranged in the bracket, the adjusting rod is arranged in the bracket, one end of the adjusting rod passes through the bracket and is inserted into the round tube. The end of the pipe joint away from the round tube is connected to the bearing seat connected to the car.
[0044] like Fig.13 As shown, the suspension rod connects the slide frame and the car, the car is divided into two parts: a seat and a platform, and the car includes a chassis, a middle plate and an upper plate.
[0045] like Fig.14 As shown, the chassis is assembled by a frame and a corner frame into a square frame with cut corners at four corners, a car main beam and a car sub-beam are welded at the center of the chassis, the car sub-beams are symmetrically arranged on both sides of the car main beam, the car main beam and the car sub-beam are arranged in a cross shape, a baffle is welded at the connection between the car main beam and the car sub-beam, a pillar is provided in the middle of the car main beam, and the pillar is perpendicular to the chassis.
[0046] like Fig.15 As shown, the middle plate is arranged parallel to the chassis and on the seat part, a seat cushion is arranged on the middle plate, and one flat end of the middle plate is fixedly connected to the support.
[0047] like Fig.12 and Fig.17 As shown, the upper plate is arranged above the middle plate, a handrail is provided in the middle of the upper plate, a bearing seat is provided at the bottom of the car, a positioning plate is provided at the intersection of the pillar and the handrail, the suspension rod is connected to the pillar, and the car can rotate freely around the pillar.
[0048] like Fig.16 As shown, a seat back is provided above the connection between the middle plate and the car.
[0049] like Fig.18As shown, a mounting plate is fixedly provided on the flange of the upper part of the main beam.
[0050] When used specifically,
[0051] Since the working area of the corridor elevator is relatively long, it is impossible to use a towing cable to control it and adopt the driving mode of an AC motor. Therefore, a DC driving mode with a power device built into the car is adopted, which has the characteristics of simple structure, safety and reliability.
[0052] The positioning plate is used for axial positioning of the car. The hole on the positioning plate fits smoothly with the round tube and is lubricated with grease. When the car is in a balanced state, the radial force on the positioning plate is not very large, so the car can rotate freely around the hanger. The handrails and pillars are welded and fixed. The positioning plate should be pre-inserted into the round tube in the hanger. If necessary, a locking handwheel can be added to the main column. When the car does not need to rotate, the locking handwheel can be fixed to the round tube.
[0053] The mounting plate can slide arbitrarily after being embedded in the flange of the upper part of the main beam, so it is easy to install. The mounting plate can adopt an integral cast steel structure or a combined welded structure. The mounting plate is used for linear guides and arc guides.
[0054] When the guide rails are concavely connected, it is also suitable to use inclined connection between different types of guide rails, which is mainly used at the turning point at the bottom of the stairs. The angle between the two guide rails is generally 145°. The joint ends of the guide rails need to be cut to achieve seamless connection. The chain plate is a V-shaped connector, and the connecting plate is also a V-shaped structure. It can be spliced with two identical connecting plates. When the sprocket runs to the corner, it should be able to achieve a smooth transition, switching from one guide rail to another.
[0055] When the guide rails are convexly connected, it is also applicable to the inclined connection between different types of guide rails, which is mainly used at the turning point at the top of the stairs. The angle between the two guide rails is also 145°, which is similar to the concave connection. The chain plate can be used in both concave and convex types, and only needs to be turned over. The connecting plate is umbrella-shaped and can be turned over when splicing. The sharp corners of the joint at the lower flange of the main beam should be ground to ensure that the sprocket can achieve a smooth transition.
[0056] The sprocket is directly mounted on the output shaft of the worm gear reducer, so there is no need to set other parts such as the main shaft and bearing seat on the slide, which greatly simplifies the structure. However, there should be a positioning boss at the output shaft of the reducer to facilitate installation and ensure that the center distance size remains unchanged. The sprocket chain transmission pair generally adopts an enveloping working state, like a belt transmission pair, because multiple teeth are involved in the work at the same time, the work is more reliable and less likely to derail. The sprocket chain transmission pair in the present invention works in a linear state, that is, only one tooth is involved in the work, which is equivalent to a gear rack transmission pair. Therefore, higher requirements are placed on the mechanical strength and wear resistance of a single tooth. A sprocket with a larger modulus (chain number) should be used as much as possible to avoid tooth wear or even breakage due to overload. Due to structural reasons, the possibility of derailment is very small, but if it is not handled properly, it may get stuck at the corner, so a looser meshing state is better.
[0057] The car rotates freely around the suspension rod and can adopt the most suitable orientation in different applications. The diagonal length of the bottom plane of the car is about 1 meter, which is slightly smaller than the effective inner width of the stairs, so it will not be stuck and the rotation will be obstructed. Small items that you carry with you can also be placed under the seat cushion.
[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
