When the elevator car is installed in a corridor, the elevator car can be directly installed without modifying the corridor, so that the elevator car can move close to a railing of the original corridor. The anti-collision system can be arranged on the elevator car, when a pedestrian is detected, the elevator car can automatically stop, and the collision of the pedestrian is avoided. This part is prior art and will not be described in detail here.
As a preferred embodiment, the original balustrade of the corridor can be repositioned, i.e. the balustrade 39 is brought slightly closer to the side of the wall, leaving room for the elevator car 15 to travel between two staircases 41 in different directions, i.e. so that the elevator car 15 travels outside the balustrade 39, as shown in fig. 7.

The opening and closing type integral effect of the elevator door is similar to that of a bus door. The outer door 35 can be opened and closed by being driven by an air cylinder.
According to the width (1.2 m-1.5 m) of the stairs of the existing elevator-free building, in order to ensure that the stairs have enough space for people to pass after being installed and people have relatively comfortable moving space in the elevator car, one optional size of the elevator car is as follows: the width was 0.6m, the front and rear lengths were 0.7m, and the height was 1.9 m. Because the invention is additionally arranged in the existing corridor, in order to bring more convenience for passengers to carry luggage and provide a comfortable space, a hollow stool can be arranged in the elevator car 15, the stool is used for people to sit, and the luggage is placed under the stool.
In addition, according to the actual situation, a luggage rack can be arranged outside the elevator car to convey relatively large luggage, and the design mode can save the whole volume of the elevator car.
When the invention is installed in a corridor, an upper fixed base 8 and a lower fixed base 46 in the transmission mechanism are fixedly connected with a girder bottom plate of a stair section through expansion bolts. The transfer guide rail 4 is connected to the upper and lower fixed bases 8 and 46 by an adjustable angle rail support 6. The adjustable angle guide support 6 may be of the prior art. The inclination angle of the conveying guide rail 4 can be correspondingly adjusted according to different inclination angles of different corridor stair sections.
Taking the example of lifting one floor, the working process of the invention comprises the following steps:
1) when in an initial position, the locking gear 17 of the elevator car 15 is locked with the transmission slide block track 3, the chain wheel 11 and the annular transmission chain 9 rotate under the driving of the transmission driving device 14, and the transmission slide block track 3 moves obliquely upwards along with the annular transmission chain 9; when the conveying slide block track 3 approaches the reversing sliding table mechanism 200 and reaches a preset position, a travel switch on the upper fixed base 8 is triggered, the power supply of the conveying driving device 14 is disconnected, and the chain wheel 11 and the annular transmission chain 9 stop working.
2) Then, the reversing driving device 27 is started, the lead screw 22 drives the reversing slider rail 20 to move from the original position to the reversing proximity switch I31, after the reversing proximity switch I31 is triggered, the reversing driving device 27 is powered off, the reversing slider rail 20 stops moving, and at the moment, the reversing slider rail 20 corresponds to the position of the elevator car 15.
(this step 2) is only present when the elevator is initially used. This step is not repeated during the recycling of the elevator after it has been put into operation. )
3) And the contracting brake stepping speed reducing motor 19 on the elevator car 15 is started, the locking state of the locking gear 17 and the rack I2 is released, and the elevator car 15 enters rail changing movement. At the moment, the contracting brake stepping speed reducing motor 19 drives the locking gear 17 to move in a matching way with the rack I2, and drives the elevator car 15 to enter a reversing slide block track 20 in the reversing sliding table mechanism 200; when the elevator car 15 moves to a preset position, the band-type brake stepping reduction motor 19 stops working, and the locking gear 17 and the rack II 33 are locked with each other, so that the locking between the elevator car 15 and the reversing slide block track 20 is realized.
4) And the reversing driving device 27 is started again to drive the screw rod 22 to rotate, the reversing slide block track 20 runs towards the reversing proximity switch II 24, after the reversing slide block track reaches a preset position, the proximity switch II 24 is triggered, the reversing driving device 27 stops working, and at the moment, the reversing slide block track 20 corresponds to the conveying slide block track 3 in the conveying mechanism 100 on the next stair section in position.
5) The locking gear 17 and the rack II 33 are unlocked, the elevator car 15 is switched again, and the next conveying mechanism 100 enters the conveying slide block track 3 to continue running.
The invention selects the number of the transmission mechanisms 100 and the number of the reversing sliding table mechanisms 200 to be installed according to the number of floors when in installation, namely the whole elevator is repeatedly composed of the transmission mechanisms 100 and the reversing sliding table mechanisms 200. The operation of the whole set of elevator is completed under the control of the control device, and the specific control part can be correspondingly designed according to the working steps of the invention. As shown in fig. 7, when the elevator car 15 travels above (or diagonally above) the landing door 40, the elevator car 15 is supported on the upper landing section in front of the landing door and passengers enter and exit.
In this embodiment, the height of the elevator car is not sufficient to support on the platform in front of the entrance door, and an auxiliary step 34 is preferably attached to the body of the elevator car 15.
The auxiliary steps 34 are mounted on the housing of the elevator car 15 by means of a rotary shaft which is rotatable relative to the elevator car 15, and an auxiliary step drive gear 45 is keyed to the rotary shaft.

In this embodiment, the auxiliary steps 34, when rotated downward, may be supported on a platform in front of the access door 40 to facilitate passenger access to the elevator car 15.
The auxiliary step 34 may have 1-3 steps or may be designed as a small slope as shown in fig. 9.
In order to ensure the safety of the elevator, key parts of part of the bearing capacity, such as the upper fixing base 8, the lower fixing base 46 and the reversing fixing base 23, are of an integral casting type structure, and in order to reduce the load of the original building, the casting is preferably performed by adopting an aluminum alloy material. In addition, the length-to-diameter ratio of the screw 22 and the conveying guide rail 4 and the reversing guide rail 21 may not be too large to ensure sufficient rigidity. A reversing proximity switch is arranged above the screw rod 22 through a proximity switch support frame 25, and the positioning function of the reversing proximity switch can ensure that the transmission slide block track 3 is accurately butted with a car bearing slide rail 16 at the top end of the elevator car 15.
The elevator car changes the rail from the chain wheel transmission rail to the rail changing sliding table, and then changes the rail from the rail changing sliding table to the chain wheel transmission rail, and the elevator repeatedly operates in the corridor space according to the sequence action and is controlled by necessary signals to form an operation system of the whole novel cableway elevator.
