Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and examples. It should be understood that the following specific examples are only for illustrating the present invention and are not to be construed as limiting the present invention.

The invention provides an elevator running system with a single elevator shaft and a plurality of elevator cars distributed in a linear array, which comprises at least three elevator shafts arranged in sequence, wherein two elevator shafts are internally provided with vertical rails and at least two elevator cars running simultaneously, one elevator shaft is used as a rising channel, the other elevator shaft is used as a falling channel, the third elevator shaft is used as a pause channel, the pause part of each elevator car layer on the front wall and the rear wall of a car door is provided with a transverse moving rail, each elevator car is provided with a vertical motion power mechanism driving the elevator car to rise or fall along the vertical rails, and a horizontal transverse motion power mechanism transferring the rails to the transverse moving rails to move left or right.

The following is described in detail in connection with four hoistway embodiments.

Referring to fig. 1, the elevator running system of the present invention is implemented by the following technical solutions: the elevator operation system comprises 4 elevator shafts, a first elevator shaft I, a second elevator shaft II, a third elevator shaft III and a fourth elevator shaft IV which are distributed in a linear array, and compared with the operation of a single elevator shaft and a single car of the traditional traction type lifting rope elevator, the elevator operation system has the following characteristics:

1) the invention has 4 elevator shafts: i.e. the first hoistway only as a hoistway, the middle second and third hoistways only as a parking hoistway and the fourth hoistway only as a descent hoistway.

2) The same elevator shaft allows a plurality of cages to run simultaneously, and the running of each cage is not influenced by the running of other cages. Namely, the first elevator shaft is used as a lifting passage to allow a plurality of elevator cars to simultaneously ascend to different floors, and the mutual operation is not influenced by other cars; the fourth hoistway acts as a hoistway to allow multiple elevator cars to descend to different floors simultaneously and travel between each other unaffected by the other cars.

3) The function of the intermediate pause channel is as follows: (1) when a car in the ascending channel ascends to a certain floor and stops, the car does not run temporarily, namely the car can horizontally move to the middle second elevator shaft pause channel, and when the car needs to ascend at a certain nearby floor, the car in the second elevator shaft pause channel at the floor can transversely move to the ascending channel to further ascend; when a certain car in the descending passage descends to a certain floor and stops, the car does not run temporarily, the car can horizontally move to the middle third elevator shaft pause passage, and when the car needs to descend at a certain nearby floor, the car of the third elevator shaft pause passage at the floor can transversely move to the descending passage to further descend. (2) The cars of two channels in the middle of the second elevator shaft and the third elevator shaft can move left and right transversely to each other: that is, if the 4 th hoistway descending passage requires a car to descend, the car that can be suspended by the second hoistway is moved to the fourth hoistway descending passage through the third hoistway and then is lowered to a designated floor. Similarly, if the first hoistway ascending lane requires the car to ascend, the car of the third hoistway suspension lane may also be moved to the first hoistway ascending lane through the second hoistway and then ascend to the designated floor. (3) The second and third elevator shaft intermediate suspension channels have another function that when the electric quantity of a certain car is insufficient, the car can be stopped in the intermediate suspension channel for charging, and the operation of other cars is not influenced.

4) The outer door of the elevator car (the door installed on the wall of the building) can be selectively placed in the middle two pause passages of the second elevator shaft and the third elevator shaft and can also be placed in the ascending passage of the first elevator shaft and the descending passage of the fourth elevator shaft. The car outer door is placed in the middle of the second elevator shaft and the third elevator shaft to have two pause channels: when the lift car ascends to a designated floor, the lift car moves to the second lift shaft pause passage to carry out passenger access, so that other running lift cars in the first lift shaft ascending passage cannot be influenced. Similarly, when the cage descends to a designated floor, the cage moves to the third shaft suspension passage for passengers to enter and exit, so that other running cages in the fourth shaft descending passage cannot be influenced. The disadvantages are that: after the elevator car reaches the appointed floor, the elevator car needs to move transversely to the middle second and third elevator shaft pause passages, and passengers can not experience well when taking the elevator. The advantage if the outer elevator door is placed in the first hoistway rising path and the fourth hoistway falling path: passengers can directly enter and exit after the elevator arrives at the appointed floor, and the passengers can enter and exit without waiting for the elevator car to move to the intermediate pause passage in a traversing mode. The disadvantages are that: when a certain cage arrives at a certain floor, if the time taken for passengers on the certain floor to enter and exit the cage is too long, the operation of other cages in the passage is influenced. The two door opening schemes have advantages and disadvantages respectively and can be selected according to requirements.

Based on the above car operation characteristics, some conclusions about the elevator mechanical structure scheme can be drawn:

1) the power mechanism is required to be arranged on the lift car, so that the lift car can independently run and is not influenced by the running of other lift cars; therefore, the traditional hoisting mechanism with a hoisting rope lifting structure of a traction type elevator, a screw type elevator lifting structure, a hydraulic type elevator lifting structure, a screw rod lifting mechanism, a chain and chain wheel lifting mechanism in a stereo garage and other power mechanisms which are not arranged on the car cannot be used in the invention, otherwise, when a certain car runs and goes wrong, other cars are easily affected.

2) The elevator hoisting mechanism and the traversing mechanism cannot interfere in space.

3) The cages of the two pause passages in the middle of the second elevator shaft and the third elevator shaft have the capability of mutually moving left and right, so that all the cages of the 4 elevator shafts can flow to move to a certain appointed floor randomly.

Referring to fig. 2, the car lifting mechanism of the present invention is:

1) 4 vertical rails 10 assembled by a plurality of sections of racks are arranged on the front wall and the rear wall of an elevator shaft car door, and two ends of each vertical rail 10 are in a concave arc shape;

2) vertical motion power mechanisms are arranged on the front surface and the rear surface of the car door: 4 first electric motors 1 and a gear mechanism 11.

With reference to fig. 4 and 5, the car lateral movement mechanism of the present invention is:

1) a horizontal transverse power mechanism is arranged at the bottom of the car: the horizontal transverse power mechanism has three actions: (a) the overall lifting action of the horizontal transverse moving mechanism: the four second motors 2 arranged on the side wall of the car drive the screw rod 201 to rotate, and the screw rod 201 is matched with a screw rod sliding block (not shown) fixedly arranged on the bottom plate 202, so that the bottom plate 202 is driven to lift in the vertical direction relative to the car; (b) the wheels 21 are capable of a front-to-back telescopic action in a direction perpendicular to the car door: four third motors 3 arranged on the bottom plate 202 drive a driving wheel 31 to rotate, the driving wheel 31 is positioned at one end of a synchronous belt 32, a sliding plate 33 is connected with the synchronous belt 32, a fourth motor 4 and wheels 21 are arranged on the sliding plate 33, and the sliding plate 33, the fourth motor 4 and the wheels 21 integrally realize telescopic action vertical to the direction of the car door along with the synchronous belt 32; (c) rolling action of the wheels: the four fourth motors 4 drive the wheels 21 to rotate so as to realize the linear motion of the wheels on the traverse rail 20.

Referring to fig. 2 and 3, a small section of track 30 whose rotation angle can be controlled by the fifth motor 5 (hereinafter referred to as a cross track) is installed at the intersection of the vertical rack track and the traverse track: one surface of the rail 30 is processed into a rack, and when the motor controls the rail at the intersection to rotate to a vertical state, the rail is connected with a rack rail fixed on the elevator shaft wall to form an uninterrupted vertical rail; one side of the cross track is processed into a transverse track, and when the cross track rotates 90 degrees from a vertical state to a horizontal state, the cross track is connected with the transverse track to form an uninterrupted transverse track. The two ends of the crossed track are in a convex arc shape, so that the crossed track is ensured not to interfere with the vertical track and the transverse track after rotating.

When the lift car needs to ascend/descend, the track at the cross position is controlled by the fifth motor 5 to rotate to the vertical direction and is connected with the rack track fixed on the lift well wall to form an uninterrupted vertical track, the first motor 1 on the lift car drives the gear to be meshed with the 4 rack tracks on the lift well wall, and the lift car is lifted along the rack tracks on the lift well wall.

Referring to fig. 5, when the car needs to be moved from vertical movement to horizontal traversing movement, the rail at the intersection is controlled by a fifth motor 5 to rotate to the horizontal direction, and is engaged with the traversing rail fixed on each floor of the elevator shaft wall to form an uninterrupted traversing rail. The third motor 3 at the bottom of the car drives the wheels 21 to extend outwards to the position right above the transverse moving track in the direction perpendicular to the car door, and then the second motor 2 at the bottom of the car drives the 4 wheels 21 at the bottom of the car to move downwards in the vertical direction until the wheels are contacted with the transverse moving track. Finally, the fourth motor 4 at the bottom of the car drives the wheels 21 to rotate so as to realize the transverse movement of the car.

Referring to fig. 6, when the car needs to move from horizontal traversing movement to vertical lifting movement, the track at the cross position is controlled by the fifth motor 5 to rotate to the vertical direction, and is connected with the rack track fixed on the elevator shaft wall to form an uninterrupted vertical track, the car traverses to the position where the gear on the car is meshed with the vertical rack track, then the second motor 2 at the bottom of the car drives 4 wheels 21 to be upwards received in the vertical direction, and after the wheels 21 are separated from the contact with the cross rails 20, the third motor 3 at the bottom of the car drives the wheels to be received towards the center of the car, so that the wheel module does not interfere with the traversing tracks of other floors when the car is vertically moved.

The spacing distance between two adjacent cages on the 1 st elevator shaft ascending channel and the 4 th elevator shaft descending channel needs to meet the requirement, and a plurality of cages can be allowed to run simultaneously. Assuming that the time required for the cage to ascend from the 1 st floor to the 2 nd floor in the vertical direction is t1 and the time required for the cage to traverse from the 1 st hoistway to the 2 nd hoistway in the horizontal direction is t2, the ascending path in the vertical direction allows a plurality of cages to travel simultaneously as long as t1> t2 is programmed and the precondition that the distance between adjacent cages must be greater than the distance of 1 floor is satisfied. For example, if car 1 at floor 1 of the hoistway needs to be raised to floor 10 and car 2 at floor 3 needs to be raised to floor 7, car 1 at floor 1 and car 2 at floor 3 can run simultaneously: when the No. 2 cage of the 3 rd floor rises to the 7 th floor, the No. 1 cage of the 1 st floor originally rises to the 5 th floor, and when the No. 1 cage continues to rise from the 5 th floor to the 6 th floor, the No. 2 cage stopped at the 7 th floor already moves to the 2 nd elevator shaft pause passage and does not collide with the No. 1 cage continuing to rise from the 6 th floor. Similarly, the 4 th hoistway of the 4 th cage can allow a plurality of cages to run simultaneously by the descending path in the vertical direction on the premise that the distance between the adjacent cages must be greater than the distance of 1 floor.

It should be noted that when 3 elevator shafts are adopted, the collision accident caused by the fact that the bridge box is stopped in the elevator shaft stopping passage is avoided through the sensor and software control.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention in any way, and any person skilled in the art can make many changes or modifications to the equivalent embodiments without departing from the scope of the present invention.
