Description

Technical Field

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

[0002] Currently, there is a kind of corridor chair elevator, whose chair adopts gear mechanism to run and transmit, but the gear mechanism has high manufacturing precision, high cost, complex installation and small carrying capacity. The purpose of the present invention is to provide a corridor lifting mechanism, which adopts wheel type to run and transmit, is relatively simple to manufacture and install, has low cost and large carrying capacity. Summary of the invention

[0003] The purpose of the present invention is to solve the problem of the corridor lifting mechanism, more precisely, to solve the problem of the existing corridor chair elevator, whose chairs are transmitted by gear mechanism, which has high manufacturing precision requirements, high cost, complex installation and small carrying capacity. The purpose of the present invention is achieved by the following technical solution.

[0004] The corridor lifting mechanism of the present invention comprises an upper guide rail, a lower guide rail, a lifting rod, an upper driving wheel, a lower driving wheel, a motor, etc. The guide rail has a rough stress surface. The lifting rod is hollow in the middle and is used to install a transmission member. An upper driving wheel and a lower driving wheel with the same diameter are installed on the lifting rod, and the driving wheel is a solid tire. Specifically, the upper guide rail and the lower guide rail are laid and fixed on the stairs one by one along the stairs handrail, and the upper and lower guide rails are parallel to each other. The upper driving wheel on the lifting rod is buckled on the upper guide rail, and the lower driving wheel is buckled on the lower guide rail. At the same time, the lifting rod is perpendicular to the ground, so that it is connected to the upper and lower guide rails in a rolling manner. In order to ensure the verticality of the lifting rod and the ground, a verticality control wheel is installed on the lifting rod to the outer side of the bottom of the upper guide rail. The side of the lifting rod and the side wall of the guide rail adopt rolling contact, of course, sliding contact can also be adopted. The guide roller is installed on the side of the lifting rod or the side wall of the guide rail in rolling contact. The motor is fixedly mounted on the lifting rod and is connected to the upper and lower driving wheels, or is connected to one of the driving wheels, and the other driving wheel serves as a passive wheel. In this way, the motor starts to drive the driving wheel to rotate, so that the lifting rod moves along the guide rail. With the forward and reverse gears of the motor, the lifting rod moves up and down along the guide rail. Compared with the gear mechanism of the existing corridor chair elevator, the invention has the advantages of low cost, simple manufacturing and installation, and large carrying capacity. After the carrying component is fixedly mounted on the lifting rod of the lifting mechanism, it can be used to carry passengers up and down the stairs. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0010] Figure 1 In the first embodiment shown in the figure, the guide rail shape is as shown in the figure, specifically, the upper guide rail 1 is fixed on the stair ceiling along the stairs, and the lower guide rail 2 is fixed on the stair treads along the stairs, and the upper guide rail 1 and the lower guide rail 2 are parallel to each other. The driving wheel on the lifting rod 3 is a single wheel, and the upper driving wheel 4 is buckled on the upper guide rail 1, and the lower driving wheel 5 is buckled on the lower guide rail 2. Figure 3 As shown, the lifting rod 3 is made perpendicular to the ground, so that it is connected to the upper and lower guide rails in a rolling manner. In order to ensure the verticality of the lifting rod and the ground, a verticality control wheel 7 is installed on the lifting rod 3 and is close to the outer side of the bottom of the upper guide rail. The side of the lifting rod is in rolling contact with the side wall of the guide rail. Specifically, guide rollers 8 are installed at the positions of the two sides of the lifting rod 3 and the side walls of the upper guide rail 1 and the lower guide rail 2. Its motor 6 is fixedly installed on the lifting rod 3 and is connected to the upper and lower drive wheels in a transmission manner, or is connected to one of the drive wheels in a transmission manner, and the other drive wheel serves as a passive wheel. The lower drive wheel of this embodiment can be increased by a passive wheel, so that the lower drive wheel has two wheels to increase stability.

[0011] Figure 2 In the second embodiment shown, the guide rail shape is as shown in the figure, specifically, the upper guide rail 1 is fixedly installed on the stair ceiling along the stairs, and the lower guide rail 2 is fixedly installed on the stair treads along the stairs, and the upper guide rail 1 and the lower guide rail 2 are parallel to each other. The driving wheels on the lifting rod 3 are double wheels, the upper driving wheel 4 is buckled on the upper guide rail 1, and the lower driving wheel 5 is buckled on the lower guide rail 2. Figure 3 As shown, the lifting rod 3 is made perpendicular to the ground, so that it is connected to the upper and lower guide rails in a rolling manner. In order to ensure the verticality of the lifting rod and the ground, a verticality control wheel 7 is installed on the lifting rod 3 and is close to the outer side of the bottom of the upper guide rail. The side of the lifting rod is in rolling contact with the side wall of the guide rail. Specifically, guide rollers 8 are installed on the two sides of the lifting rod 3 and the side walls of the upper guide rail 1 and the lower guide rail 2. Its motor 6 is fixedly installed on the lifting rod 3 and is connected to the upper and lower drive wheels in a transmission manner, or is connected to one of the drive wheels in a transmission manner, and the other drive wheel serves as a passive wheel. The drive wheels of this implementation scheme are double wheels, one of which should be designed as an active wheel and the other as a passive wheel, or a differential device should be used.

[0012] In all the above embodiments, the motor is powered on to start, driving the driving wheel to rotate, so that the lifting rod moves along the guide rail, and as the motor shifts forward and backward, the lifting rod moves up and down along the guide rail. After the carrying component is fixedly installed on the lifting rod of the lifting mechanism, it is used to carry people up and down stairs.
