Description

Technical Field

[0001] The present invention relates to an elevator, and more particularly, to a corridor elevator. Background Art

[0002] Currently, there are some corridor chair elevators that use gear traction for lifting and lowering. This gear traction requires high manufacturing precision, is expensive, complex to install, and has a small carrying capacity. The purpose of the present invention is to provide a corridor elevator that uses wheel-mounted lifting and lowering. This wheel-mounted elevator is relatively simple to manufacture and install, has a low cost, and has a large carrying capacity. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems of existing corridor chair elevators, specifically to solve the problems of existing corridor elevators that use gears to pull up and down, which require relatively high manufacturing precision, are expensive, complex to install, and have a small carrying capacity. The purpose of the present invention is achieved through the following technical solutions.

[0004] The staircase elevator of the present invention comprises an upper guide rail, a lower guide rail, a lifting rod, an upper connecting bridge and a lower connecting bridge each with a wheel mounted at each end, an electric motor, a transmission wheel, a guide roller, and a carrying member. Specifically, the upper and lower guide rails are laid one above the other along the staircase and fixed to the staircase so that the upper and lower guide rails are parallel to each other. The upper connecting bridge and the lower connecting bridge are respectively buckled onto the upper and lower guide rails. A lifting rod is connected perpendicular to the ground to the upper and lower connecting bridges. A transmission wheel is mounted at each intersection of the lifting rod, the upper connecting bridge, and the lower connecting bridge. A motor is mounted on the lifting rod and is transmission-connected to the upper and lower transmission wheels. The upper and lower transmission wheels are in turn transmission-connected to one of the wheels on the corresponding connecting bridges; the other wheel is a driven wheel. Rolling contact is achieved between the side of the lifting rod and the sidewalls of the guide rails. Specifically, guide rollers are mounted on the lifting rod or the guide rails. The carrying member is mounted on the lifting rod.

[0005] Another implementation of this stair elevator eliminates the transmission wheel in the above method and uses two electric motors with the same rotational speed. Other aspects of the above method are the same. Specifically, an electric motor is installed on each of the upper and lower connecting bridges. Each motor is in driving connection with one of the wheels on the corresponding connecting bridge. This wheel is the driving wheel, and the other is the driven wheel.

[0006] When the motor is powered on, the upper and lower drive wheels rotate synchronously, causing the lift rod to move along the guide rail. As the motor shifts forward and reverse, the lift rod moves up and down along the guide rail, and the passenger member mounted on the lift rod simultaneously moves up and down along the guide rail, thereby carrying passengers up and down the stairs. The present invention has the advantage of utilizing wheel-mounted operation and lifting, which is relatively inexpensive, simple to manufacture and install, and has a large carrying capacity compared to existing stairway chair elevators that rely on gears for lifting.

[0011] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments:

[0012] Figure 1 In the first embodiment shown, the guide rail is shaped as follows Figure 3 Specifically, the upper guide rail 1 is laid along the stairs and fixed on the stair ceiling, and the lower guide rail 2 is laid along the stairs and fixed on the stair treads, and the upper guide rail 1 and the lower guide rail 2 are made parallel to each other. The upper connecting bridge 4 is buckled on the upper guide rail 1, and the lower connecting bridge 5 is buckled on the lower guide rail 2. At the same time, the lifting rod 3 is connected to the upper connecting bridge 4 and the lower connecting bridge 5 perpendicular to the ground. A transmission wheel 8 is installed at each intersection where the lifting rod 3 is connected to the upper connecting bridge 4 and the lower connecting bridge 5. The motor 7 is installed on the lifting rod 3 and is connected to the upper and lower transmission wheels 8. The upper and lower transmission wheels 8 are then connected to one of the wheels 6 on the corresponding connecting bridge, so that the wheel becomes the driving wheel. Rolling contact is adopted between the side of the lifting rod and the side wall of the guide rail, specifically as shown in the figure. Figure 3 As shown, guide rollers 9 are installed on both sides of the lifting rod 3 at positions where the two sides of the lifting rod 3 contact the side walls of the upper guide rail 1 and the lower guide rail 2. A carrying member 10 is installed on the lifting rod 3.

[0013] Figure 2 The second embodiment shown here eliminates the transmission wheel of the first embodiment and employs two electric motors of the same rotational speed. Other aspects of the embodiment are the same as those of the first embodiment. Specifically, an electric motor 7 is mounted on each of the upper connecting bridge 4 and the lower connecting bridge 5. Each motor is in driving connection with one of the wheels 6 on the corresponding bridge, making that wheel the driving wheel.

[0014] In the above two embodiments, the motor is powered on and started, the upper and lower drive wheels rotate synchronously, and the lifting rod runs along the guide rail. As the motor shifts forward and reverse, the lifting rod moves up and down along the guide rail, and the carrying member installed on the lifting rod moves up and down along the guide rail at the same time, which is used to carry people up and down the stairs.

[0015] In the two embodiments described above, the connection between the lifting rod and the connecting bridge can be fixed or movable. The movable connection can be a hinge type, for example. Of the two wheels on the connecting bridge, the passive wheel can be a universal wheel. Alternatively, both wheels can be simultaneously connected to the motor as driving wheels. The passenger structure can be a car, a seat, or the like. The guide rails can have other shapes.
