Problems solved by technology

[0002] In modern buildings, elevators are necessary operating equipment for high-rise buildings. Due to their high cost and operating costs, and occupying a certain area and space of the building, most low-floor buildings (generally below six floors) In particular, floors with a long service life are not equipped with elevators, which brings inconvenience to residents living above the third floor, especially for middle-aged and elderly people and the infirm, sick and disabled, traveling is more inconvenient. In order to provide convenience for people who live and live in low-rise buildings, the invention patent with the authorization announcement number of CN2554145Y and the authorization announcement date on June 4, 2003 discloses a "low-rise chain elevator". The vertical lifting structure has the problems of complex structure, high cost, and large space occupation, which is not conducive to installation and use in low-rise buildings; the invention patent with the authorized announcement number of CN1234591C and the authorized announcement date of January 8, 2006 discloses a "Stairwell Automatic Rotating Escalator Running Track", its main structure is to install the up and down running track on the handrail in the stairs, install the manned box on one side of the handrail, and drive the manned box to follow the stairs of the building by pulling the rope through the motor. The trajectory runs up and down, but because the rotary escalator is installed on one side of the handrail, its disadvantages are: first, the structural strength of the handrail must be increased, otherwise it will cause the manned box to be pulled and deformed after being loaded, and it will not be able to run Even the phenomenon of being scrapped; the 2nd, this revolving escalator is installed on the side of handrail, and the manned box occupies certain corridor space, makes the spacing of its stairs narrow, when people walk in the stairwell, especially when carrying objects, just It will be impossible to pass because the stair spacing is too small; the third is that when the passengers are on different floors, they cannot see the action status of other floors and people walking on the stairs. People cause injury, very unsafe; Fourth, the structure of the spiral escalator is complicated, the cost is high, and the maintenance is very inconvenient, which is not conducive to installation and use in low-rise buildings; the authorization announcement number is CN2926161Y, and the authorization announcement date is July 2007 The invention patent on the 25th disclosed a "low floor stair elevator", its main structure includes motor, gear transmission, sprocket, chain, wire rope, counterweight, fixed pulley, elevator assembly, bearing, transmission shaft, guide rail The base, the electromagnetic brake and the slideway fixed in the base of the guide rail; the present invention also includes a proximity switch, a micro switch and a moving pulley; the bases of the two guide rails are placed relatively parallel and fixed in the inclined bases on both sides of the stairs respectively Each slideway is equipped with two movable pulleys fixedly connected with the bottom end surface of the ladder assembly, the front end of the ladder assembly is fixedly connected with one end of the chain, and the other end of the chain is fixed to the front end of the counterweight by bypassing the sprocket Connection, the sprocket is installed on the transmission shaft and connected with the output shaft of the motor through the gear transmission device, the transmission shaft is equipped with an electromagnetic brake, the two ends of the transmission shaft are installed on the guide rail base through bearings, the rear end of the counterweight is connected with the One end of the wire rope is fixedly connected, and the other end of the wire rope is fixedly connected to the rear end of the elevator assembly by bypassing the fixed pulley, and the fixed pulley is fixedly connected to the base of the guide rail. There is a micro switch connected to the guide rail base directly under the wire rope, and the front and rear ends of the guide rail base are respectively equipped with proximity switches.
Its defect is: the one, this stair lift is arranged on the whole stair top, must use this stair lift, wasted energy, and original stair is just useless, has lost use value; The 2nd, this stair lift uses chain to carry out transmission , lubrication and maintenance must be ensured uninterruptedly during operation, otherwise it will rust and cause breakage, resulting in personal injury and poor safety performance; third, the stair elevator has a complex structure, difficult installation, high cost, and very inconvenient maintenance

Embodiment Construction

[0031] Examples such as figure 1 Shown, a kind of low-floor walking-replacing elevator comprises the support device 3 consistent with the inclination of the stairs, and the support device 3 comprises an upper support beam 5 and a lower support beam 24 arranged in parallel up and down, and a lower support beam 24 is installed on the lower support beam 24. The crossbeam 24 is parallel to the guide rail 13, and the positions near the two ends of the guide rail 13 on the lower support beam 24 are respectively provided with proximity switches 27. The man-carrying device 7 that can move up and down along the guide rail 13 is installed on the guide rail 13. 7 is connected with the transmission of the power drive device, and the power drive device includes a stepper motor 9 fixedly installed on the manned device 7, the stepper motor 9 adopts a special motor with a brake function of 220 volts and 550 watts as power, and Add a program-controlled integrated circuit board to make the mach...

Abstract

The invention discloses a low floor walking-replacing elevator. The elevator comprises a supporting device consistent with the inclination degree of a staircase. The supporting device is arranged on the wall of one side of the staircase; the supporting device comprises an upper supporting beam and a lower supporting beam which are arranged in up-down parallel; a guide rail parallel to the lower supporting beam is arranged on the lower supporting beam; a man carrying device capable of moving along the guide rail up and down is arranged on the guide rail; and the man carrying device is in transmission connection with a power driving device. As the walking-replacing elevator is arranged on the side of the staircase against the wall, the walking-replacing elevator is steady without affecting the normal use of the staircase. The walking-replacing elevator is generally arranged on a floor higher than a third floor, mainly carries a single person, especially middle and old-aged people as well as weak, sick and disabled people to go upstairs / downstairs, is more convenient, and can carry small-volume goods as well.
