Description
Technical Field
The invention relates to the technical field of elevators, in particular to a suspension rail type escalator.
Background
Currently, with the acceleration of population aging, elevator installation in old communities has become a civil engineering with urgent national advocacy and common people's demands. At present, an elevator additionally installed in an old community mainly adopts three modes, namely a traditional vertical lifting elevator, a straight rail type escalator installed by depending on a stair tread, and a rotary type escalator installed at a stair railing position. The three elevators can solve the problem of going upstairs and downstairs of high-rise households in the current old community due to the fact that no elevator exists. However, due to the inherent characteristics, various contradictions and defects exist in the process of installing the elevator in the old community, the popularization difficulty is high, and the specific analysis is as follows:
1. The defects and contradiction points of the traditional vertical lift elevator in old community transformation are analyzed:
The elevator is characterized in that an elevator shaft is additionally arranged on the outer vertical surface of an old community, an original corridor ventilating window of the community is changed into an entrance door opening of the elevator, and the elevator shaft is connected with the flat-layer stair surface of the old community through building a corridor. The elevator car vertically runs up and down in the elevator shaft to vertically lift the user to the target floor, so that the problem of going up and down the stairs is solved. The elevator is composed of a traction system, a safety system, a counterweight balancing device, a control system, a car and the like, and the main principle of the elevator is that a traction motor pulls the car to vertically ascend or descend, so that the aim of conveying passengers to a specific floor is fulfilled. The elevator has the advantages of mature technology, safety, reliability, attractive and elegant appearance, large carrying capacity, high operation efficiency, simple and convenient operation and the like, and becomes a main mode for additionally installing the elevator in the current old community. However, in the implementation process of old cell reconstruction, the elevator is found to have the following problems:
Firstly, the engineering cost is high. Currently, the cost of adding a 6-floor car type vertical lift elevator is generally about 40 to 60 ten thousand, and even if the government is subsidized by fifty percent in a part of areas, the cost of sharing more than twenty ten thousand by owners is still a large cost, and the cost is still a little cost for each owner. This limits to some extent the attractiveness of old cells to which elevators are attached.
Secondly, the construction period is long. After the owner reaches the installation agreement, the elevator constructor needs to survey the construction site and design and manufacture the construction drawing, and the elevator constructor can actually enter the construction stage after finishing the construction. In the construction process, the elevator shaft is built in a layer-by-layer increasing mode, namely after the first floor is built, the second floor frame can be constructed, and multiple layers of frames can not be constructed at the same time, so that the operation efficiency is limited to a certain extent. Therefore, the working period of the conventional vertical lift elevator is generally more than one month, and the overlong construction period has a certain influence on the normal life of an owner to a certain extent.
Thirdly, the transformation amplitude is large. Because the old community has no elevator shaft, in the elevator installation process, the original corridor ventilation window needs to be changed into a door opening for the elevator to enter the home, and meanwhile, the elevator corridor and other accessories need to be installed, so that the original floor structure is changed to a certain extent, and the lighting, fire fighting and other aspects of the old community are affected to a certain extent. Meanwhile, when the elevator shaft of the outer wall is subjected to severe weather such as typhoons, the stress of the wall body is influenced to a certain extent, and potential safety hazards exist to a certain extent. When the vertical elevator is additionally installed in an old community, an elevator shaft can change the original sewage pipeline system of the community, and the original straight sewage pipeline is generally transited through 4 90-degree bent pipes, so that the risk of blockage of the sewage pipeline of the old community can be increased to a certain extent. The existence of these drawbacks suppresses to some extent the need for old cells to be fitted with elevators.
Fourth, the layer cannot be reached. At present, the mode of going into the door opening is generally reformed into through stair ventilation window to the additional installation of vertical lift elevator, and elevator arrival position is generally the intermediate floor in the middle of the floor, and middle floor promptly, but not directly get into resident flat floor position, still need walk half layer and just can be in the family after the passenger takes the elevator arrival, has reduced passenger's elevator's use experience to a certain extent.
2. Analyzing the defects and contradiction points existing in the old community transformation of the straight rail type escalator installed by depending on the stair surface:
The elevator is a new type of elevator that has appeared in recent years. The elevator is characterized in that an elevator track is fixedly arranged on a stair surface on one side close to a wall and comprises a transmission mechanism, a folding pedal, a transmission gear and the like. The rack device is arranged on the track, and the gear arranged on the transmission mechanism is mutually matched with the rack under the drive of the driving motor, so that the aim of going upstairs and going downstairs is fulfilled, and the problem of inconvenient going upstairs and downstairs of the old is solved. The elevator has the advantages of low manufacturing cost, convenient and efficient installation, short construction period, small transformation amplitude and the like, has certain application value, but has the following defects in the specific use process:
firstly, the transportation quantity is small. The elevator is characterized in that the rail is arranged on one side of the stair surface close to the wall, a certain amount of offset exists between the pedal position and the rail, and the gravity center of the passenger is not positioned at the center of the rail, so that the stress of the rail is uneven, and therefore the elevator can only transport one passenger to go upstairs and downstairs at a time, and the popularization and the use of the elevator are limited to a certain extent.
And secondly, the floor cannot directly reach. Since the elevator cannot realize the turning function, after reaching the flat floor, the passengers need to change direction through the flat floor and then transfer another pedal. Therefore, the elevator needs to be transferred for a plurality of times to reach the target floor, the conveying efficiency is low, and the popularization and the application of the elevator are limited to a certain extent.
Thirdly, the corridor space is occupied. The rail of this elevator is directly laid on the step face of stair, generally is about 20 centimeters apart from the wall body, can occupy certain corridor space, and the rail direct mount is on the stair face, and the pedestrian appears falling injury problem because of stepping on the rail easily when the corridor walks, has certain potential safety hazard.
3. The defects and contradiction points of the rotary escalator installed at the stair railing part in old district reconstruction are analyzed:
The elevator is a novel elevator with a rail arranged at the position of a stair railing, well solves the problem that a straight rail elevator arranged on a stair tread needs continuous transfer and cannot be directly reached, has the advantages of low manufacturing cost, short installation period and the like, has certain competitiveness, but also finds certain problems in a specific use process, and particularly has the following defects:
First, the capacity is insufficient. The elevator is an elevator laterally arranged at the handrail part of the stair, and passengers can stand or sit on corresponding seats to achieve the purpose of ascending and descending. Meanwhile, as the turning radius of the elevator is smaller, the turning speed is not smooth enough, the uncomfortable feeling of passengers riding the elevator is increased, and the experience of the elevator is affected to a certain extent.
Secondly, the operation efficiency is lower. Since the turning radius of the elevator is relatively small, the necessary deceleration operation is a necessary choice for enhancing the safety and comfort of the elevator. Therefore, the lower-speed running speed limits the large-scale popularization and use of the elevator to a certain extent, and can only meet the use requirements of the old and the family, but not the use requirements of the passenger flows in the old and the old communities.
Thirdly, the transformation amplitude is relatively large. The elevator is characterized in that the track is a special track and is attached to a stair or a specially arranged support, so that the original corridor handrail needs to be modified during modification, and the special handrail matched with the track is installed, so that the problem of high construction cost is caused to a certain extent.
Through the analysis, the problems of lack of elevators in old cells can be solved to a certain extent, but due to the inherent contradiction and deficiency of the elevators, the current old cells are more urgent in elevator installation, but the progress is still slower, and management after installation is also lack of definition, so that the problems of elevator installation in the old cells are more contradictory. Therefore, the novel elevator with low manufacturing cost, safety, high efficiency and large carrying capacity is provided, and the requirements are urgent.
The invention discloses a suspended corridor elevator, which comprises an I-shaped steel type track device and a monorail train, wherein the track device and the monorail train are fixedly arranged on a roof corresponding to a stair slope section and a roof corresponding to a stair turning platform, the monorail train comprises a track car device connected in series, the track car device comprises a bearing support, two groups of bearing wheel pairs are symmetrically arranged at two sides of the upper end of the bearing support, the bearing wheel pairs are respectively clamped in grooves in the abdomen of the track device, the lower edges of the two groups of bearing wheel pairs are respectively contacted with the upper end face of the lower flange of the track device and can roll on the flange, the bearing support is rotatably provided with a bearing suspender, the other end of the bearing suspender is hinged with a riding pedal, the track car device is provided with a driving gear, the driving gear is meshed with a transmission rack at the middle part of the lower end face of the track device, and a driving motor drives the driving gear to rotate. The elevator is too simple in structure, solves some existing problems to a certain extent, but cannot effectively solve the difficulties in the improvement of the elevator in the old community, and has no specific technical scheme in the technology of changing the straight rail into the bent rail, so that the elevator can not smoothly change the rail and run, and the technology does not have substantial progress and breakthrough.

Compared with the prior art, the invention has the advantages that:
1. Compared with the traditional car type vertical lifting elevator, the elevator has the following advantages:
1. The manufacturing cost is low. Firstly, the elevator itself is low in cost. Because the invention has special structural characteristics, the aim of the upward and downward movement of the elevator is realized only by installing the rail on the back of the stair, and the manufacturing cost is saved to a certain extent. Secondly, the advantages of simple structure and convenient installation are achieved. Only the rails are needed to be additionally arranged on the back of the stairs, facilities such as an elevator shaft are not needed to be additionally arranged, and the original floor structure is not needed to be modified, so that the manufacturing cost is saved to a certain extent.
2. The construction period is short. The invention is additionally arranged in a mode of arranging the track on the back of the stair, equipment such as the lift car, the power transmission device and the like are manufactured in a factory building, and only the track, the cable bracket and the like are required to be installed during installation. The invention can simultaneously install the rails on a plurality of floors without waiting for the installation of the rails on the first floor to finish the installation of the rails on the second floor, and only needs to position the size of each layer of rails and then fold the rails, and the cables are laid after the folding is finished, so that the construction period is shortened to a certain extent, and the operation efficiency is improved.
3. The transformation amplitude is small. In the installation process, the invention does not need to refit the original ventilation window, stairs and other parts, does not need to additionally install facilities such as an elevator shaft, and does not need to change a district sewage pipeline, and only needs to additionally install facilities such as a sleeper beam, a track and the like on the original stairs, the sleeper beam is fixed with a wall body through expansion screws, an elevator electric control box is additionally arranged at a third floor position, and an up-down floor selection button is additionally arranged at each floor, so that the elevator installation work can be completed with smaller change amplitude.
4. Can reach the flat layer. Because the elevator realizes the ascending or descending transportation of passengers by arranging the rails, if one cell is 6 floors, one straight rail to 6 floors and half straight rail and half circular rail on the floor can be additionally arranged on the floor of the 6 floors, and a track reaching the top of 6 floors is additionally arranged on the other side of the semicircular track of the floor, so that the elevator can reach the floor of 6 floors, and the aim of entering a house on the floor is fulfilled.
2. Compared with the existing straight rail pedal type escalator, the escalator has the following advantages:
Firstly, continuous operation is possible. The existing straight rail pedal type escalator is characterized in that a straight rail is additionally arranged on each stair, an operation motor is arranged on the straight rail to achieve the purpose of ascending and descending passengers, after one stair is operated, the passengers need to go down to a second elevator through a flat floor and then reciprocate in sequence until reaching a target floor, the operation procedure is complicated, the elevator can not be generally operated, the requirement of additionally arranging the elevators in old communities is met, and the elevator is only suitable for families. The invention realizes the direct arrival of floors through a dragging motor and a pre-distribution track, thereby solving the defect that the elevator needs continuous transfer.
And secondly, the carrying capacity is large. Firstly, the special layout mode of the track of the elevator determines that the elevator has larger bearing capacity. The elevator is characterized in that the center of the track of the elevator is the middle position of the gravity center of the elevator car, the stress is relatively uniform, the requirement on the track is reduced, and the carrying capacity is improved, and the elevator is composed of a dragging motor, a universal connecting rod, an elevator car supporting seat, an elevator car and the like, before the elevator is installed, the elevator can flexibly match the number of the elevator cars according to the passenger flow of the elevator in the district, and 4 pedals can be parked on a flat floor at the same time, if the number of the pedals is increased, only other pedals are required to be parked on the upper steps of the floor, and the requirement of large carrying capacity is met.
And thirdly, the conveying efficiency is high. The invention adopts the flat semicircular track to realize the reversing purpose, has soft turning experience, does not need to reduce the running speed of the whole elevator due to smaller turning radius, can realize the up-and-down requirement on passengers with stable running speed and stable turning experience, and improves the conveying efficiency.
3. Compared with a curve track type pedal escalator/seat type escalator, the escalator has the following advantages:
first, the capacity is large. The curve elevator is a new type of elevator with rails mounted near the stair railing. The elevator has the advantage of being capable of reaching the target floor directly, but can only transport one passenger in the running process due to the fact that the elevator is stressed laterally, the transporting efficiency is low, and popularization and application of the elevator are limited to a certain extent.
Secondly, more intelligent. Because the operation system of the elevator is basically the same as that of the traditional vertical elevator, when in operation, the elevator can directly strike the target floor only by pressing the floor selection button in the elevator car, and passengers do not need to press the up switch or the down switch by themselves in the whole course, so that the operation is simpler.
Meanwhile, the elevator has the following advantages:
firstly, the space occupation is small. Because the car of this elevator adopts collapsible mode, and the car expands when passenger uses, leaves the car back car and automatic folding, leaves sufficient space for walking stair personnel, can not cause the interference to walking on the personnel on the stair in the operation in-process of elevator. Meanwhile, after the elevator is folded, the influence on freight transportation is small, the elevator occupies the original stair space less, and other households cannot be influenced.
Secondly, the noise is low. The rail wheel of this elevator is the rubber gyro wheel, and the elevator is less at the in-process noise of operation, reduces the influence to the resident.

Detailed Description
Referring to fig. 1 and 2, the basic principle of operation is that a rail sleeper 74 is installed on the back of the corridor stairs of the old district, and a rail 8 is fixed to the rail sleeper 74. The power transmission device 2, the car supporting seat 3 and the universal connecting rod seat body 4 are fixedly arranged on the track 8 through a positioning track wheel 43, a vertical separation type transmission shaft assembly 47 and a horizontal separation type transmission shaft assembly 48. The lift car 6 is connected with the lift car supporting seat 3, the universal connecting rod seat body 4 and the power transmission device 2 are connected with each other through the universal connecting rod 7, and the lift car 6 performs a spiral ascending or spiral descending motion around the track 8 under the driving of the power transmission device 2.
Referring to fig. 5, 6, 11, 12, 13, 15, 18 and 19, the principle is further described that the rail sleeper beam 74 is mounted on the back of the stair 73, the locking end of the rail sleeper beam 74 is locked with the right angle position of the stair step, the other side is fixed with the wall body through an expansion screw, and the rail connector 23 on the rail 8 is mounted on the rail sleeper beam 74. The track 8 consists of a flat layer semicircular track 20 and a straight track 22, wherein an arc-shaped rack 21 is arranged on the outer side of the flat layer semicircular track 20, and a rack 24 is arranged on the straight track 22. At the junction of the straight rail 22 and the flat layer semicircular rail 20 is the overlapping area of the rack teeth, which is about 5-7 teeth. The purpose is that when the power transmission device 2 enters the flat layer at the end of the straight rail 22, the second gear 80 on the horizontal separation type transmission shaft assembly 48 on the power transmission device 2 automatically turns into the flat layer semicircular rail 20, and the horizontal separation type transmission shaft assembly 48 arranged on the power transmission device 2 automatically enters the rack 24 on the straight rail 22 under the pushing of the second gear 80, so as to finish the reversing from the flat layer semicircular rail 20 to the straight rail 22. The cooperation mode enables the car to realize turning and reversing on the premise of a single-row rack and a single power source. The elevator is guaranteed to be uninterrupted and free of blocking in the running process, the purpose of stable lifting is achieved, and the riding comfort of the elevator is improved. The universal connecting rod fixed slot 45 is arranged on one side of the power output device 2, the fixed slot 45 is matched with the sphere 56 of the universal connecting rod 7, the other end of the universal connecting rod 7 is connected with the universal connecting rod seat 4, the other side of the universal connecting rod seat 4 is matched with the universal connecting rod 7 through the universal connecting rod 7, the other end of the universal connecting rod 7 is connected with the universal connecting rod fixed slot 45 on the car supporting seat 3, the purpose of the power output device is to realize that the power output device 2 drags the car 6 to realize horizontal turning, the straight rail 22 can stably reciprocate when transiting to the horizontal semicircular rail 20, and a single power source drives a plurality of sections of cars to ascend or descend simultaneously, so that passengers can be sent to corresponding floors.
Referring to fig. 11, 12 and 13, when the drag motor 39 generates a forward or reverse rotational torque, the rotational torque is transmitted to the vertically split drive shaft assembly 47 through the bevel gear 46 and the drive shaft 49, and the bevel gear 52 at the upper end of the vertically split drive shaft assembly 47 is meshed with the bevel gear 52 on the horizontally split drive shaft assembly 48. The second gear 80 mounted on the vertically split propeller shaft assembly 47 and the horizontally split propeller shaft assembly 48 begins to rotate in synchronization. When the power transmission device 2 runs on the straight rail 22, the second gear 80 arranged on the horizontal separation type transmission shaft assembly 48 is meshed with the rack 24 on the straight rail 22, and the elevator is driven to move up or down on the straight rail 22 under the pushing of the dragging motor 39.
The first gear 54 mounted on the vertically split propeller shaft assembly 47 is free of racks on the sides of the straight rail 22, thereby creating an idle phenomenon. When the power transmission device 2 reaches the position of the flat layer semicircular track 20, the overlapping racks with 5-7 teeth are overlapped at the joint area of the straight rail 22 and the flat layer semicircular track 20, so that when the power transmission device 2 transits from the straight rail 22 to the flat layer semicircular track 20, the first gear 54 arranged on the vertical separation type transmission shaft assembly 47 is matched with the racks on the flat layer semicircular track 20, and the second gear 80 on the horizontal separation type transmission shaft assembly 48 is matched with the racks on the straight rail 22, so that the transition of the power transmission device 2 from the straight rail 22 to the flat layer semicircular track 20 is realized.
After the transition of 5-7 teeth is completed, since the flat layer semicircular track 20 is only provided with the arc-shaped rack 21 on the side surface and no rack is arranged above the flat layer semicircular track, the first gear 54 on the vertical separation type transmission shaft assembly 47 is matched with the arc-shaped rack 21, and at this time, the horizontal separation type transmission shaft assembly 48 is supported by the hollow track wheel 53, and the second gear 80 idles. The power transmission device 2 now makes a flat turn under the urging of the first gear 54 on the vertically split propeller shaft assembly 47.
When the power transmission device 2 is simultaneously arranged at the joint of the tail end of the flat semicircular track 20 and the head end of the straight track 22, the overlapping area is 5-7 teeth. When the power transmission device 2 passes through the overlapping area, the first gear 54 on the vertical separation type transmission shaft assembly 47 forms idle running, the driving force is converted into the second gear 80 which is arranged on the horizontal separation type transmission shaft assembly 48 and is matched with the rack 24 on the straight rail 22, the elevator is driven to move upwards or downwards, and the power transmission device 2 realizes the reversing from the flat layer semicircular rail 20 to the straight rail 22.

Referring to fig. 20, fig. 20 is a pedal operation posture diagram simulating the elevator in a flat layer turning. The pedal dimensions are about 50cm long and about 30cm wide, and the radius of the flat semicircular track is about 50cm. In this state, the 4 cars can be satisfied at the same leveling position to complete the turning operation at the same time. The problem that the car cannot touch every two vertex angles in the turning process can be simulated through the graph. If the number of the cars needs to be increased continuously, the two cars are arranged at the same interval.
Referring to fig. 21, fig. 21 is a logic operation diagram of an elevator. The working principle is that when someone presses the upper and lower layer selection buttons 70 on any floor, signals are sent to an elevator electric control system, the elevator electric control system sends selection instructions to a logic control and distribution circuit, and the running direction of the elevator is judged according to the floor where the elevator is located at the moment. If the passenger presses the button in floor 3, the elevator is in floor 1, and then the logic control circuit judges that the motor needs to rotate forward, after judging, the command signal is sent to the dragging motor through the safety circuit, and the dragging motor rotates forward to perform uplink operation. When the power transmission device 2 reaches a flat floor, a flat floor signal is sent to an elevator control system, the elevator electric control system judges that the motor needs to stop running and sends a stop signal to a dragging motor, and the dragging motor stops rotating after receiving a command to finish the arrival work of the elevator. After the elevator arrives at the station, a passenger gets on the elevator and presses a floor selection button 10 of the building 1, the floor selection button 10 sends a building sending signal to be achieved to an elevator electrical control system, the elevator electrical control system sends the signal to a logic control and distribution circuit, the motor is judged to need to move reversely according to the logic relation from the building 3 to the building 1, an electric signal is sent to a dragging motor 39 through a protection circuit, the dragging motor 39 after receiving the instruction starts to move reversely, a power transmission device 2 drives the elevator to move downwards, after the elevator arrives at the building 1, a flat floor arriving signal is sent to an elevator electrical control system, after receiving the flat floor signal, the elevator electrical control system transmits a stopping instruction to the dragging motor, the dragging motor 39 after receiving the instruction stops rotating, the descending action is completed, and the passenger conveying process is completed once.
The elevator electric control box 69 is installed on the middle floor of each building, and aims to save the length of a cable, and the cable winch 5 can control the operation of the elevator by twisting half of the cable.
The outer layers of the positioning rail wheels 43 and the hollow rail wheels 53 are provided with rubber layers, so that noise among the positioning rail wheels 43, the hollow rail wheels 53 and the rail 8 is reduced when the elevator runs, and quietness of the elevator during running is improved.
Because the corridor stairs of the old community only reach the level position of 6 floors, the elevator can not continue to reach 6 floors or other attic through the installation of the track sleeper beam 74. In order to achieve the purpose of achieving the landing of the elevator 6 floors or other highest floors, 1 extension track beam 78 (fig. 22) is additionally arranged on the landing of the 6 floors or other highest floors to form 6-layer half, one end of the extension track beam 78 is connected with the 6-layer half semicircular track 20, the other end of the semicircular track 20 is connected with one end of a second extension track beam 78, and the other end of the extension track beam 78 is fixed on the roof 79 of the top floor.

When passengers get off the elevator, the car folding rod can automatically fold under the acting force of the reset spring.
The specific operation method of the invention comprises the following steps:
When passengers on any floor need to go upstairs and downstairs, the upper and lower layer selection buttons are pressed down to call the elevator. After receiving the instruction, the elevator autonomously judges whether to move upwards or downwards according to the logic relation. When the elevator runs to the floor where the passenger is located, the elevator automatically stops running and is in a passenger-receiving state, and the elevator car is in a folding state. At this time, the passenger commands the elevator to automatically expand in a card swiping mode. After the car is completely unfolded, passengers enter the car, the folding armrests are closed, and the circuit is in a state to be operated. Then, the passenger presses the button of the required floor, after receiving the instruction, the elevator automatically judges the ascending or descending, and after reaching the target floor, the elevator automatically stops running.
After reaching the destination floor, the passenger opens the folding handrail 14, at which point the circuit is in a power-off state. When the passenger leaves the car, the folding pedal 15 is automatically folded by the driving of a return spring or a motor installed in the upper folding joint 12. Before the pedal 15 is folded completely, the double switch is in an off state, and the whole elevator is in a stop state at the moment, no matter how other floors press the floor selection buttons up and down, or other car passengers press the floor selection buttons, the whole elevator is in a stop running state, and the elevator is ensured to be in a stop state in the folding process.
