Description

Technical Field

[0001] The invention relates to the field of old residential corridor elevators, and in particular to a novel corridor elevator track system. Background Art

[0002] There are a large number of old multi-storey residential buildings in my country that are not equipped with elevators, which brings a lot of inconvenience to people's normal lives. At present, there are two main ways to install elevators in old residential buildings: ordinary elevators installed outdoors and corridor elevators installed in indoor stairwells. Since ordinary elevators need to occupy a lot of outdoor space and affect the use of residents, the installation is subject to many restrictions. Therefore, corridor elevators have become another direction to solve the problem of installing elevators in multi-storey residential buildings.

[0003] The common staircase elevators are divided into two categories according to the track installation position: lower track type and upper track type. The lower track type means that the running track of the passenger seat is installed on the handrail side of the lower part of the stairs, and the seat is set on the track. Driven by the drive device, the passenger seat runs along the track. The upper track type means that the running track of the passenger seat is installed on the ceiling or side wall above the stairs, and the seat is hung on the track. Driven by the drive device, the passenger seat runs up and down along the track to achieve the purpose of carrying people up and down the stairs.

[0004] However, the current practices have their own advantages and disadvantages: the lower track installation will occupy the width of the stairs, affecting fire evacuation; the second is that the turning radius of the track at the stair platform is too small, the running speed is slow, affecting the use; the third is that the lower track type can only operate with a single seat. Although the upper track installation does not occupy the width of the stairs, the current practice can only operate with a single seat, that is, it can only meet the use of one person, which seriously affects the efficiency of multi-story residential buildings. At the same time, there are many lines and debris in the stairs, and the track laying is subject to many restrictions. At the same time, the operation of the elevator has a certain impact on the entrances and exits of residents on each floor. Although some technologies (such as a cross-type running track for corridor elevators CN 217264115 U) have proposed new solutions, the technology is relatively complex. Summary of the invention

[0005] The purpose of the present invention is to overcome the above problems existing in the prior art and to provide a new type of corridor-type elevator track-type technical solution. By laying running tracks above the stairs and providing track avoidance areas, the problem of multi-seat operation can be solved while reducing space occupancy.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A novel corridor elevator track system includes a track system laid above stair steps, side walls and rest platforms, a seat system suspended on the track, and an operating system for controlling the operation of the seats. The seat system moves up and down along the track by power traction, and the operating system controls the operation of the seat system.

[0008] The track system consists of an inclined track located at the bottom of the staircase or on the side wall of the stairwell on each floor, a horizontal track located at the bottom of the floor platform or rest platform (half-floor position of the staircase), and a movable track. The track turns are connected by rounded corners to meet the needs of operation. The inclined track and the horizontal track at the floor platform are both single tracks. According to the number of floors, parallel horizontal double tracks (inner track of the rest platform and outer track of the rest platform) are set at two or more rest platforms of the stairs. The distance between the double tracks is at least 1m to meet the needs of two-way operation. A connecting track and two movable tracks are set at the intersection of the double track and the inclined track. The two movable tracks are divided into straight movable tracks and arc-shaped movable tracks. The movable tracks can move up and down to change the elevation according to the needs of line operation to meet the needs of the seat system running at different track positions and solve the problem of multiple seats intersecting. The connecting track is the bifurcation node where the single track turns to the two movable tracks, and a certain gap is left at the connection with the movable track. When the connecting track is at the same elevation as the arc-shaped movable track and the inner track of the rest platform, the straight movable track is lifted to a certain height so that the seat system can run along the arc-shaped movable track; when the connecting track is at the same elevation as the straight movable track and the outer track of the rest platform, the arc-shaped movable track is raised so that the seat system can run along the straight movable track and the outer track of the rest platform.

[0009] The linear movable track and the arc-shaped movable track are supported on specially designed worm gears, and the movable track is alternately lifted or lowered by the rotation of the worm gears. The worm gears mainly consist of a driving wheel, a turbine driving wheel, a turbine driven wheel, a left worm, a right worm, a pull rod, and a support platform. The support platform is fixed above the stair rest platform by a pull rod, and the driving wheel, the turbine driving wheel, the turbine driven wheel, the left worm, and the right worm are installed on the support platform. The driving wheel is electrically driven to engage with the turbine driven wheel to rotate, thereby driving the turbine driving wheel, and then driving the left and right worms to rotate to rise and fall respectively, thereby lifting or lowering the linear movable track and the arc-shaped movable track.

[0010] All rails have the same cross-section, with grooves on the upper surface and concave on the left and right sides. The grooves and left and right concave widths are 3cm, heights are 5cm, and concave slot-type teeth are used. This allows the gears in the drive device to run along the grooves, and the rollers in the drive device to run in the concave spaces on both sides, creating a safer approach.

[0011] The seat system includes a suspension rod, a seat and a drive device. The suspension rod is fixedly connected to the seat and the drive device respectively. The drive device is electrically driven and installed on the track. The drive device is connected to the track through a roller clamp, a chain, and a gear, and the seat is driven along the track through the chain. The seat can be flipped and folded to reduce the space occupied when parked. The seat system can be set up in multiple sets and parked at different floors to meet the needs of people on different floors to use it at the same time.

[0012] The operating system is controlled by a single-chip microcomputer and includes a control device on the seat, a sensing device on the track, and a calling device on the floor platform. The control device on the seat is provided with buttons for controlling up and down movement and emergency braking. The calling device is installed on the floor platform of each floor, and the calling device is provided with a calling button wirelessly connected to the control device. The sensing device is installed in sections to sense the operating position of the seat.

[0013] The beneficial effects of the present invention are as follows: by laying parallel double tracks and movable tracks at the stair rest platform, a single track is turned into a partial double track, and the seats are made to run along different tracks through the up and down movement of the movable track, thereby creating a track intersection avoidance area, making it possible to set up multiple manned devices on the track, thereby improving the utilization efficiency of corridor elevators in multi-story residential buildings.

The walls and staircases are arranged in a spiral ascending direction and are suspended above the staircase 1, floor platform 2 and rest platform 3 respectively; the seat 7 is installed on the track system through the suspension rod 8 and the driving device 9, the control device 11 is installed on the seat 7, and the operating system controls the seat system to run on the track system; the summoning device 12 is installed at each floor platform, and the summoning device 12 is provided with a summoning button wirelessly connected to the control device 11, so that the resident can summon the seat system to the location as needed; the sensing device 13 is installed above the track at the floor platform 2 and the rest platform 3, and is wirelessly connected to the control device 11 to sense the running position of the seat.

[0023] like Figure 2As shown, the inclined track and the horizontal track at the floor platform are both single tracks. According to the number of floors, parallel horizontal double tracks (i.e., the inner track 6.1 of the rest platform and the outer track 6.2 of the rest platform) are arranged at each rest platform of the stairs. The distance between the double tracks is at least 1m to meet the needs of two-way operation. Two movable tracks (a straight movable track 10.2 and an arc-shaped movable track 10.3) are arranged at the junction of the single track and the double track, i.e., one end of the connecting track 10.1 is connected to the straight movable track 10.2 and the arc-shaped movable track 10.3, and one end is connected to the inclined track 4, while the straight movable track 10.2 is connected to the outer track 6.2 of the rest platform, and the arc-shaped movable track 10.3 is connected to the inner track 6.1 of the rest platform.
