Description

Closed corridor elevator

Technical Field

The utility model relates to an elevator field especially relates to a closed corridor elevator.

Background

The aging pressure becomes one of important factors which troubles the social development of China in the next decades, and the prior development social endowment service is written into the twelve-five program, which meets the national importance of endowment career. However, in the multi-storey houses (5-9 stories) built in the eighties and ninety years and later in China, the vertical traffic problem of the multi-storey houses becomes the most critical problem which troubles the normal life of the aged population in cities because no elevator is installed. Governments all over the country try and find good ways to solve the problem, particularly, schemes for installing box elevators in old multi-storey houses in Guangzhou, Shanghai, Beijing and other places are tried, but various problems are exposed in the process of trying, and the new schemes for solving the problem are found out that the old multi-storey houses are not ideal, so that the new schemes cannot be popularized nationwide. All parties seek and explore a more reasonable and effective mode to solve the problem of difficult climbing of the multi-storey residential buildings, and the corridor elevator is produced at the same time.

The existing corridor elevator can be divided into an exposed type and a closed type: the carrying device is wholly exposed and is called an exposed type; the combined carrying device has an integral shell, and only a pedal, a handrail, a seat board and other parts slightly protrude out of the shell after reset, so the combined carrying device is called as a closed type. Structurally, the closed-type stairway elevator has an integral enclosure, while the exposed-type stairway elevator has no integral enclosure. When the closed corridor elevator receives the instruction to carry the device to run automatically, even if someone leans on the elevator, it is safe, and when the exposed corridor elevator receives the instruction to run automatically, people in front of the carrying device can not occupy the corridor arbitrarily, otherwise, the elevator is easy to be damaged by collision, so that the elevator has potential safety hazard. Compared with an exposed corridor elevator, the closed corridor elevator is complex in structure and high in manufacturing cost.

For example, the invention patent with the patent number 'ZL200710071436. X' named 'a corridor elevator' has the structure as follows: each corridor is taken as a unit, a corridor elevator capable of independently operating is respectively installed on each corridor, the corridor elevator is installed on the inner side surface of each corridor, the corridor elevator comprises a ladder frame arranged in the direction of the slope of each corridor, and an upper rail, a lower rail, a rail car, a traction device, a sealing device and a control system are arranged on the ladder frame. The relay type working mode greatly improves the working efficiency of the equipment, and the elevator adopts a sealing device, thereby reducing the failure rate and ensuring the neat and beautiful appearance. However, in the aforementioned document, the pedal is restored and then is hidden in the housing, and the opening of the gate is first required when the pedal is turned out, which means that the time required for the pedal to turn out is long.

On the basis of the technical scheme described in the patent documents, the chinese utility model patent with the publication number CN205151453U discloses a built-in pedal of a corridor elevator, which comprises a closed belt arranged in an elevator frame for operation and a connecting panel always exposed out of the elevator frame, wherein the connecting panel is provided with a storage cavity for storing the pedal. The invention changes the mode that the footplate can move out or retract into the corridor elevator at a specific position in principle, and realizes that the footplate can directly enter or exit the storage cavity at any position of the running track of the elevator. Therefore, the problem of retraction and extension of the pedal is solved, the control part of the original gate is omitted, the cost is reduced, the internal device is simplified, and the installation and the replacement are convenient. However, the technical scheme has the defect that when the corridor elevator runs, the closed belt, the connecting panel and the pedal all need to move along the stairs under the action of the traction device of the rail car. The reason is that the scheme changes the mode that the pedals can be moved out or retracted into the corridor elevator at a specific position, the pedals can be moved out or retracted at any position through the synchronous motion of the connecting panel, and the connecting panel is used as a part of the shell, so that the closed structure of the corridor elevator can be realized only by arranging the synchronous motion of the closed belt during the motion of the connecting panel. However, in the scheme, the corresponding traction force of the sealing belt, the connecting panel and the pedal is also required to be larger, and the cost is higher; and this solution is more vulnerable.

Therefore, the utility model discloses the creation envisions a new construction's closed corridor elevator.

On the basis, the existing corridor elevator pedals are in two states of turning out and taking in, the corridor elevator can be used by users standing when turning out, and the corridor elevator can run in no-load when taking in, so that the corridor elevator cannot be damaged due to collision. The drive pedal of the corridor elevator mainly has two modes, and firstly, a drive motor directly drives the pedal through a gear. The second is that the folding is pulled by the elasticity of the return spring and the folding is pulled by the driving motor through the soft strips such as the steel cable, the chain and the like. The first technical proposal can refer to a railway car structure for a corridor elevator recorded in Chinese utility model patent text with the bulletin number of CN 202164005U. According to the scheme, the pedal is directly driven by the driving motor through the gear, so that the driving motor, the gear and the pedal are in a rigid connection state, and the driving motor and related parts are easily damaged when the pedal is forced to be turned out or retracted by external force due to misoperation. The second technical scheme can refer to the 'pedal folding and unfolding structure of a corridor elevator' described in the Chinese utility model patent text with the bulletin number of CN202245619U, and the second scheme is an improvement of the first scheme, and when the pedal is forced to be turned out by a maloperation external force, because the distance between the driving motor and the pedal rotating shaft stress piece is shortened on the contrary and is connected through a soft strip, the driving motor can not be forced by the external force, and only the soft strip is in a loose state, and can not damage related parts.

However, the second solution is limited in that when a malfunction external force forcibly retracts the pedal, the malfunction external force may forcibly act on the force receiving member of the pedal rotation shaft, the flexible strip and the driving motor, which may easily cause damage to the related components.

Meanwhile, the handrail of the existing closed type corridor elevator can refer to a handrail device for the corridor elevator, which is recorded in a Chinese utility model patent publication with publication number CN 201770385U; the handrail body in the scheme is fixed on the rail car, and has a distance of several centimeters from the shell so as to be convenient for holding.

But the prior proposal that the handrail is not adjustable has at least the following disadvantages:

1, the handrail body is fixedly arranged; when the carrying device automatically runs, the handrails are easy to be jammed by people, particularly children, to cause finger clamping damage;

2, as shown in the patent drawing with the publication number of CN201770385U, the handrail body needs to be arranged to be parallel to the housing and slightly higher than the housing, and the housing height of the corridor elevator cannot be too low and occupies much space in the corridor because the handrail needs a certain height;

3, on the basis of 2, when the user takes the corridor elevator and goes down, the lower half section of the hand-held handrail body is relatively lower and relatively inclined, and the wrist posture of the user is very uncomfortable at the moment.

In order to solve the problem, the utility model aims to provide a closed corridor elevator, this corridor elevator optimize footboard upset mode to simplify corridor elevator structure, reduce cost promotes stability and makes it not fragile.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

Compared with the scheme described in the Chinese utility model with the publication number of CN205151453U in the background art, the scheme is that the rotating shaft is obliquely arranged, and the pedal is obliquely turned over along the rotating shaft; when the pedal is in a folded state, the bearing surface of the pedal is attached to the outer side surface of the shell, and two side edges of the pedal are parallel to the moving direction of the pedal along with the rail vehicle frame.

The connecting panel needs to be arranged in the patent technology with the publication number of CN205151453U, and the storage cavity is formed in the connecting panel, because the pedal is in a storage state, an included angle exists between the upper side wall of the pedal and the running direction of the pedal, if the pedal runs alone, foreign matters such as fingers of children are easily clamped and damaged at the position, and great potential safety hazards exist. In the scheme, when the pedal is in a folded state, the bearing surface of the pedal is attached to the outer side surface of the shell, and two side edges of the pedal are parallel to the moving direction of the pedal along with the rail vehicle frame. Because two sides of the pedal are parallel to the moving direction of the pedal along with the rail car frame, when the corridor elevator automatically runs, fingers of children and the like are not easy to clamp and damage; in addition, the thickness of the pedal and the seat board after being folded is equivalent to that of the pedal and the seat board, and the pedal and the seat board are separated from the thickness of the shell, so that the thickness of the shell can be obviously reduced.

Based on the scheme, the corridor elevator does not need to be provided with a connecting panel and a sealing belt, so that the cost is reduced, the structure is simplified, the operation stability of the corridor elevator is higher, and the corridor elevator is not easy to damage.

Preferably, the track frame is further provided with a seat plate mechanism, the seat plate mechanism comprises a seat plate which is hinged on the track frame through a rotating shaft and is positioned on the outer side of the shell, and an elastic reset component which drives the seat plate to be folded along the rotating shaft; the rotating shaft is obliquely arranged, and the seat plate is obliquely turned over along the rotating shaft; when the seat board is in a turning-out state, the bearing surface of the seat board is horizontally arranged; when the seat board is in a folded state, the bearing surface of the seat board is attached to the outer side surface of the shell, and two side edges of the seat board are parallel to the moving direction of the seat board along with the rail vehicle frame. Among this technical scheme, corridor elevator is except setting up pedal mechanism, still is provided with bedplate mechanism, and bedplate mechanism includes and articulates on track frame and be in the bedplate in the casing outside through the pivot, and on the basis that the footboard user was trampled, the bedplate can supply the user to take to look after the inconvenient user of standing. The seat board also adopts the overturning mode of the pedal, so details are not described, the structure of the corridor elevator is simplified, the cost is reduced, the stability is improved, and the seat board is not easy to damage.

Preferably, the side wall of the shell is provided with a first rail through hole, a second rail through hole and a plurality of protective strips which are arranged along the moving direction of the rail vehicle frame; the pedal and the seat plate respectively extend out of the shell from the first track through hole and the second track through hole; when the pedal and the seat board are in a furled state, the pedal and the seat board are provided with two side edges which are parallel to the first track through hole and the second track through hole, and the parallel side surfaces are attached to the protective strips. In the technical scheme, the first track through hole and the second track through hole are running tracks relative to the shell when the pedal and the seat plate run; the protective strips are arranged on the shell and close to one side or two sides of the folded pedal and seat board so as to prevent the pedal and the seat board from being damaged by external force; after the pedal and the seat board are folded, the pedal and the seat board form a right angle instead of a sharp angle with the protective strip, and when the corridor elevator automatically runs, fingers of children and the like are not easy to clamp and damage.

Preferably, the pedal mechanism further comprises a pedal driving device for driving the pedal to be unfolded along the rotating shaft; the pedal driving device comprises a driving part and a traction assembly connected to the output end of the driving part; the tail end of the traction assembly is connected with the pedal, and the driving component drives the traction assembly to displace along the traction direction so as to enable the pedal to rotate relative to the rotating shaft. In the technical scheme, the pedal driving device drives the pedals to be unfolded along the rotating shaft; when the elevator is not used at ordinary times or is in an idle running state, the pedals are kept in a folded state relative to the rail vehicle frame under the action of the elastic resetting component. When a user needs to take the vehicle, the pedal driving device operates to drive the pedal to turn out relative to the rail vehicle frame (simultaneously, the reset force provided by the elastic reset component is overcome), and the user can stand.

In the structure, the pedal is commonly used, so the pedal is controlled by a driving part; on the other hand, the seat plate is not frequently used, and can be manually retracted or retracted, and the driving part can be controlled when the cost allows.

Preferably, the pulling assembly comprises a spring and a pulling strip connected thereto, the spring being capable of providing a deformation length in the pulling direction. In the technical scheme, a driving part in the pedal driving device drives the pedal through the traction assembly, and the driving part drives the traction assembly to generate displacement along the traction direction so as to enable the pedal to rotate relative to the rotating shaft. When the pedal is normally used and retracted, the elastic reset component and the pedal driving device normally operate according to the scheme.

When the pedal is forced to be turned out by external force (the original state is a folded state), the rotation of the pedal does not generate traction force on the traction strip, if the distance between the output end of the driving motor and the traction force bearing end of the pedal (the tail end of the traction assembly and the connecting end of the pedal) is reduced in the background technology, the traction strip is in a loose state, and the pedal driving device cannot be damaged by the forced turning-out of the external force. When the footboard receives external force to draw in (the original state is the turn-out state), the rotation of footboard can produce traction force to the tractive strip this moment, and driving motor's output and the distance grow of the traction stress end (this case indicates the end of tractive subassembly with footboard link) of footboard, and current scheme can make the driver part atress damage under this condition, and the tractive subassembly of this scheme still includes the spring, and the spring can provide deformation length along the direction of pulling. In this case, therefore, the forced application of the external force only causes the spring to be deformed, and the pedal driving device is not damaged. When the external force is removed, the spring is recovered.

Synthesize above-mentioned analysis, the utility model discloses the last pedal mechanism of corridor elevator who relates to of creation is under the external force compulsive action of maloperation, no matter is that take in and turn over out can not damage.

Preferably, the spring is a coil spring, and the movable end of the coil spring or the end of the pulling strip is connected with the pedal; the drive member drives the pulling assembly in a radial direction relative to the coil spring. In the technical scheme, the spring is selected as the coil spring, the traction direction of the traction assembly is radial relative to the coil spring, and the length of the whole traction assembly is adjusted by rolling the coil spring.

Preferably, the rotating shaft is fixedly connected with a rotating shaft stress piece, and the rotating shaft stress piece and the pedal are positioned on two sides of the rotating shaft; the movable end of the coil spring or the end of the pulling strip is connected with the rotating shaft stress piece. In the technical scheme, the rotating shaft stress piece and the pedal are positioned on two sides of the relative rotating shaft, the traction end of the traction assembly is connected with the rotating shaft stress piece during use to drive the rotating shaft stress piece and the pedal to generate lever motion relative to the rotating shaft, and the pedal can realize larger torque under the condition of smaller torque of the rotating shaft stress piece through the lever, so that the pedal is adjusted between a folding state and a turning-out state.

Preferably, the handrail device further comprises a handrail mechanism arranged on the track frame, wherein the handrail mechanism comprises a handrail connecting rod movably arranged on the track frame, a handrail positioned on the outer side of the shell and a driving part for driving the handrail connecting rod to move; one end part of the handrail connecting rod extends out of the shell and is connected with the handrail; the driving component drives the handrail to lift relative to the shell. In the technical scheme, the rail vehicle frame is movably provided with the handrail connecting rod, the movable arrangement can be a sliding arrangement, a hinged arrangement and the like, and one end part of the handrail connecting rod extends out of the shell and is connected with the handrail. The driving part can drive the handrail connecting rod to move relative to the track frame, so that the handrail can be lifted relative to the shell.

Based on the structure, the scheme has the following technical effects:

1. the height of the handrail leaving the shell after extending out can be larger than the height of the existing handrail leaving the shell, so the height of the shell can be relatively reduced, and the space occupied by the corridor is reduced.

2. When the corridor elevator runs in no-load operation, the handrail can be close to the shell to run, so that the possibility that the handrail is touched by people by mistake can be reduced.

Preferably, one end of the handrail connecting rod is hinged on the track frame, and the driving component drives the handrail connecting rod to rotate along the hinged end of the handrail connecting rod so as to lift the handrail relative to the shell; when the handrail is at the lowest position, the axial direction of the handrail is basically parallel to the upper end surface of the shell; the axial inclination angle of the handrail at the highest position is smaller than that of the handrail at the lowest position. In the technical scheme, the handrail connecting rod is connected to the track frame in a hinged mode, and the driving part drives the handrail connecting rod to rotate along the hinged end of the handrail connecting rod; the advantage of using a hinged connection for lifting over a sliding lifting is that the axial inclination angle of the handrail changes as the height position of the handrail changes.

As described in the background art, in the prior art, the armrest body is substantially parallel to the housing, and in this state, the armrest body is inclined, and when a user takes the stairway elevator to go down, the lower half section of the armrest body held by the user is relatively low and inclined, and the wrist posture of the user is very uncomfortable. Under the scheme, when the handrail is at the lowest position, the axial direction of the handrail is basically parallel to the upper end surface of the shell; the axial inclination angle of the handrail at the highest position is smaller than that of the handrail at the lowest position. When the corridor elevator runs, as the handrail is at the highest position, the axial inclination angle of the handrail is smaller at the moment, namely the lower half section of the handrail is obviously lifted. When the user takes the corridor elevator and goes down, the lower half section of the hand-held handrail is obviously lifted, so that the user can hold the hand more suitably, and the posture is more natural.

Preferably, the driving part is directly or indirectly connected with a driving connecting rod, and the handrail connecting rod is erected on the driving connecting rod through gravity; the driving part drives the driving connecting rod to move relative to the rail vehicle frame to drive the handrail connecting rod and the handrail connected with the handrail connecting rod to lift. In the technical scheme, the output end of a driving part is connected with a driving connecting rod, and a handrail connecting rod is erected on the driving connecting rod through gravity; that is, the driving part drives the driving connecting rod to lift, and the handrail connecting rod and the handrail connected with the handrail connecting rod are only erected and placed on the driving connecting rod; the active connecting rod is lifted and descended passively along with the lifting and descending of the active connecting rod. Under the scheme, on one hand, the handrail connecting rod and the handrail connected with the handrail connecting rod can be controlled to ascend and descend through the driving part, and on the other hand, the handrail connecting rod and the handrail connected with the handrail connecting rod can also ascend and descend automatically under the action of external force. When the corridor elevator runs in no-load operation, if foreign matters are clamped between the handrail and the shell, the handrail can be lifted in the running process. Therefore, the structure can not cause the problem of finger clamping damage, and the safety is higher.

Preferably, the driving connecting rod is coaxially hinged to the handrail connecting rod, the driving connecting rod is provided with a limit stop, the handrail connecting rod can be erected on the limit stop on the driving connecting rod, and the track frame is provided with a limit baffle for limiting the lifting height of the handrail connecting rod. In the technical scheme, the handrail connecting rod can be erected on the limit stop of the driving connecting rod, so that the handrail connecting rod and the handrail thereof can be lifted passively along with the lifting of the driving connecting rod. Under the condition of no external force, the handrail connecting rod and the handrail thereof lift along with the driving connecting rod to lift passively, but under the external force, the handrail connecting rod and the handrail thereof can also lift automatically by separating from the lifting of the driving connecting rod; the limiting blocking pieces are arranged on the rail vehicle frame, and the lifting height of the handrail connecting rod is limited through the limiting blocking pieces, so that the situation that the handrail is forcibly pulled by external force and is lifted too high can be avoided.

Preferably, the driving member for driving the handrail connecting rod is a driving member in a pedal driving device; the pedal is linked with the handrail, and when the pedal is folded relative to the track frame, the handrail is positioned at the lowest position relative to the shell; when the pedal is turned out relative to the rail vehicle frame, the handrail is at the highest position relative to the shell. Among this technical scheme, thereby footboard and handrail drive through same driver part and realize the linkage, have the advantage in following two aspects:

1. the actions of the handrail and the pedal can be completed only by a single driving motor and a control part in the pedal driving device, and compared with the situation that if the handrail and the pedal respectively adopt the driving motor and the control part, the cost is reduced, and the failure rate is reduced.

2. The pedal driving device synchronously drives the handrail and the pedal, so the actions of the handrail and the pedal are linked; when the corridor elevator runs, the pedals in the pedal mechanism are in a turning-out state, the handrail is at the highest position, and at the moment, a user can sit on the pedals and hold the handrail by hands; when the corridor elevator does not run or runs in a no-load mode, the pedals are in a folded state, and the handrails are located at the lowest position.

Preferably, the traction assembly further comprises a conversion frame or a conversion connecting rod, one end of the conversion frame or the conversion connecting rod is hinged to the track frame, and the conversion frame or the conversion connecting rod is connected with the driving connecting rod to realize linkage; the spring is arranged between the conversion frame or the conversion connecting rod and the driving connecting rod or between the conversion frame or the conversion connecting rod and the pedal.

Example (b):

the closed corridor elevator shown in fig. 1-14 comprises a shell 1, a rail car frame 2 arranged inside the shell 1, a rail car traction device driving the rail car frame 2 to move inside the shell 1, and a pedal mechanism arranged on the rail car frame 2. The pedal mechanism comprises a pedal 32 hinged on the track frame 2 through a rotating shaft 31 and positioned at the outer side of the shell 1, and an elastic reset component 33 driving the pedal 32 to be folded along the rotating shaft 31. The traction device of the rail car in the scheme can refer to the traction device described in the Chinese invention patent publication with the patent number "zl 200710071436. x", and the traction device is not taken as an improvement point related to the creation of the utility model, so the traction device is omitted. The closed corridor elevator comprises a shell 1, wherein a track vehicle frame 2 is arranged inside the shell 1, the track vehicle frame 2 moves inside the shell 1 through a track vehicle traction device, a pedal mechanism on the track vehicle frame 2 comprises a pedal 32 positioned outside the shell 1, and the pedal 32 can be turned over or folded along a rotating shaft 31. When the folding chair is folded, the user can sit and stand. When the device is folded, the space is saved, and the device can avoid colliding with barriers during no-load operation.

In the above solution, if the cost is considered, the structure is simplified, and only the elastic restoring component 33 is provided; as shown in the figure, the elastic reset component 33 is a reset torsion spring, the reset torsion spring is sleeved on the rotating shaft 31, and the deformation end of the reset torsion spring is abutted against the pedal 32. When the foldable pedal 32 is used, the folding reset force of the pedal 32 is provided by the elastic reset part 33, and the pedal 32 needs to be manually pulled when being unfolded, so that the foldable pedal is inconvenient for a user to use, the user needs to bend to operate the pedal 32, and the foldable pedal is labor-saving and unsanitary. On the basis, the pedal mechanism in the scheme shown in the figure further comprises a pedal driving device for driving the pedal 32 to unfold along the rotating shaft 31, and the pedal driving device drives the pedal 32 to unfold along the rotating shaft 31. When the elevator is not used at ordinary times or is in an idle running state, the pedal 32 is kept in a folded state relative to the track frame 2 under the action of the elastic resetting component 33. When a user needs to take the vehicle, the pedal driving device operates to drive the pedal 32 to turn out relative to the rail vehicle frame 2 and overcome the reset force provided by the elastic reset component 33, so that the user can stand.

In a further preferred scheme, the rotating shaft 31 is obliquely arranged, and the pedal 32 is obliquely turned along the rotating shaft 31. When the pedal 32 is in the turning-out state, the bearing surface of the pedal 32 is horizontally arranged. When the pedal 32 is in a folded state, the bearing surface of the pedal 32 is attached to the outer side surface of the casing 1, and two side edges of the pedal 32 are parallel to the moving direction of the pedal 32 along with the track frame 2. It should be noted that the horizontal arrangement of the bearing surface of the pedal 32 in this embodiment means that the bearing surface is substantially horizontal, and does not require a completely standard horizontal arrangement. The fitting of the bearing surface of the step 32 to the outer surface of the casing 1 also includes the case where there is a gap between the step 32 and the outer surface of the casing 1. The two side edges of the pedal 32 are parallel to the moving direction of the pedal 32 along with the track frame 2, which means that the two side edges are basically parallel. The above-mentioned scheme is different from the scheme described in the chinese utility model patent with publication number CN205151453U in the background art in that the rotating shaft 31 is obliquely arranged, and the pedal 32 is obliquely turned over along the rotating shaft 31. The purpose of this is realized in that when the pedal 32 is in the folded state, the bearing surface of the pedal 32 is attached to the outer side surface of the casing 1, and two side edges of the pedal 32 are parallel to the moving direction of the pedal 32 along with the track frame 2.

The reason why the patent technology with publication number CN205151453U needs to provide a connection panel and a storage cavity is formed on the connection panel is that when the pedal 32 is in the storage state, an included angle exists between the upper side wall of the pedal 32 and the running direction of the pedal, for example, when the pedal 32 runs alone, the pedal is easy to be damaged by the clamping of foreign objects such as fingers of children, and thus, a great potential safety hazard exists. In this embodiment, when the pedal 32 is in the closed state, the bearing surface of the pedal 32 is attached to the outer side surface of the casing 1, and two side edges of the pedal 32 are parallel to the moving direction of the pedal 32 along with the track frame 2. Because two sides of the pedal 32 are parallel to the moving direction of the pedal 32 along with the rail car frame 2, when the corridor elevator automatically runs, fingers of children and the like are not easy to be clamped and damaged. In addition, the thickness of the pedal 32 and the seat board after being folded is equivalent to the thickness of the outer shell, and the thickness of the outer shell can be obviously reduced.

By the scheme, the closed corridor elevator adopts the pedal mechanism, so that the use requirements of basic users can be met. But allows for special users, especially elderly users. The track frame 2 is further provided with a seat plate mechanism, the seat plate mechanism comprises a seat plate 34 which is hinged on the track frame 2 through a rotating shaft 31 and is positioned on the outer side of the shell 1, and an elastic reset component 33 which drives the seat plate 34 to be folded along the rotating shaft 31. Among this technical scheme, corridor elevator is in addition to setting up pedal mechanism, still is provided with bedplate mechanism, and bedplate mechanism includes and articulates on track frame 2 and be in the bedplate 34 in the casing 1 outside through pivot 31, and on the basis that the footboard 32 user is trampling, bedplate 34 can supply the user to take care of the inconvenient user of standing. However, in consideration of the low frequency of the seat plate 34, the height of the seat plate 34 relative to the pedal 32 relative to the housing 1 is higher and more sanitary, so the seat plate mechanism in the present embodiment is only provided with the elastic return component 33, and the user needs to pull the seat plate 34 when the seat plate 34 is turned out. Of course, it is also possible to automate the installation of the driving means on the seat plate 34 in consideration of the use situation of the cell. In the seat plate mechanism, the rotating shaft 31 is obliquely arranged, and the seat plate 34 is obliquely turned along the rotating shaft 31. When the seat plate 34 is in the turned-out state, the bearing surface of the seat plate 34 is horizontally arranged. When the seat plate 34 is in a folded state, the bearing surface of the seat plate 34 is attached to the outer side surface of the shell 1, and two side edges of the seat plate 34 are parallel to the moving direction of the seat plate 34 along with the rail car frame 2. The seat plate 34 also adopts the overturning mode of the pedal 32 in the embodiment, thereby simplifying the structure of the corridor elevator, reducing the cost, improving the stability and ensuring that the corridor elevator is not easy to damage.

On the basis of the above scheme, as shown in fig. 3 and 4, the side wall of the housing 1 is provided with a first rail through hole 11, a second rail through hole 12 and a plurality of guard bars 13 which are arranged along the moving direction of the rail vehicle frame 2. The pedal 32 and the seat plate 34 respectively extend from the first rail through hole 11 and the second rail through hole 12 to the outside of the housing 1. When the pedal 32 and the seat board 34 are in a folded state, two side edges of the pedal 32 and the seat board 34 are parallel to the first track through hole 11 and the second track through hole 12, and the parallel side surfaces are attached to the protection strip 13. In this embodiment, the first rail through hole 11 and the second rail through hole 12 are the operation rails with respect to the housing 1 when the pedal 32 and the seat plate 34 operate. On the housing, a protection strip 13 is disposed adjacent to one side or both sides of the folded step 32 and the seat plate 34 to protect the step 32 and the seat plate 34 from external force. After the pedal 32 and the seat plate 34 are folded, the right angle is formed between the pedal and the protective strip 13 instead of a sharp angle, and when the corridor elevator automatically runs, fingers of children and the like are not easy to clamp and damage. Of course, as shown in fig. 1 and 2, if only the pedal mechanism is provided, and the seat plate mechanism is not provided, only the first rail through hole 11 is provided on the housing, and the corresponding guard bar 13 is disposed.

Above-mentioned corridor elevator optimizes footboard 32 upset mode to simplify corridor elevator structure, reduce cost promotes stability and makes it not fragile. In addition to the above innovation points, the present embodiment has the following innovation points:

1, the pedal mechanism is optimized in structure, and damage caused by forced application operation of external force is prevented;

2, the structure of the handrail mechanism is optimized, so that the handrail can be lifted, the height of the shell 1 can be reduced, and the handrail mechanism is convenient for a user to use;

3, the linkage of the handrail and the pedal 32 is realized, the operation is simplified, and the use is more convenient.

1, optimizing the structure of the pedal mechanism.

The pedal drive includes a drive member 35 and a pulling assembly coupled to an output of the drive member 35. The driving part 35 in this embodiment is a telescopic rod, which may be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod. The end of the pulling component is connected with the pedal 32, and the driving component 35 drives the pulling component to displace along the pulling direction so as to enable the pedal 32 to rotate relative to the rotating shaft 31. As shown in fig. 10, the pulling assembly comprises a spring 36 and a pulling strip 37 connected thereto, the spring 36 being capable of providing a length of deformation in the pulling direction. In the arrangement shown in fig. 6-9, the pulling assembly includes only pulling straps 37, but those skilled in the art will understand that the spring 36 of fig. 10 can be applied to fig. 6-9 as shown in connection with fig. 10. In a specific embodiment, the spring 36 is a coil spring mounted on a coil spring holder 361, a free end of the coil spring or an end of the pulling strip 37 is connected to the pedal 32, and the driving member 35 drives the pulling assembly to move radially relative to the coil spring. The pulling strip 37 is a flexible belt that can only transmit force when in a stretched, taut state, such as a chain in this embodiment; the chain is mounted on the chain holder 371. In the above technical solution, the driving part 35 in the pedal driving device drives the pedal 32 through the pulling component, the driving part 35 drives the pulling component to generate displacement along the pulling direction so as to make the pedal 32 rotate relative to the rotating shaft 31, and the length adjustment of the whole pulling component is realized through the winding of the coil spring.

The rotating shaft 31 is fixedly connected with a rotating shaft stress member 38, and the rotating shaft stress member 38 and the pedal 32 are positioned at two sides of the rotating shaft 31. The free end of the coil spring or the end of the pulling strip 37 is connected to the spindle force-receiving member 38. In the technical scheme, the rotating shaft stress piece 38 and the pedal 32 are positioned at two sides of the relative rotating shaft 31, when in use, the traction end of the traction assembly is connected with the rotating shaft stress piece 38 to drive the rotating shaft stress piece 38 and the pedal 32 to generate lever motion relative to the rotating shaft 31, and the pedal 32 can realize larger torque under the condition that the rotating shaft stress piece 38 has smaller torque through the lever, so that the pedal 32 is adjusted between a folding state and a turning-out state.

When the pedal is normally used and retracted, the elastic restoring part 33 and the pedal driving device normally operate as the scheme.

When the pedal 32 is forced to be turned out by external force, the original state is the folded state, and the rotation of the pedal 32 does not generate traction force on the traction strip 37, for example, in the case of recording the distance between the output end of the driving motor and the traction force bearing end of the pedal 32 in the background art, the distance between the tail end of the traction assembly and the connecting end of the pedal 32 is reduced, and at this time, the traction strip 37 is in the loose state, so that the external force forced to be turned out does not damage the pedal driving device. When the pedal 32 is forced to be folded by external force, the original state is a turning-out state, at this time, the rotation of the pedal 32 can generate traction force on the traction strip 37, the distance between the output end of the driving motor and the traction force-bearing end of the pedal 32 is increased, in the present scheme, the distance between the tail end of the traction assembly and the connecting end of the pedal 32 is increased, the driving part 35 can be stressed and damaged under the condition, the traction assembly of the scheme further comprises a spring 36, and the spring 36 can provide deformation length along the traction direction. In this case, therefore, the forced application of the external force only causes the deformation of the spring 36 without causing the damage of the pedal driving device. When the external force is removed, the spring 36 is restored.

And 2, optimizing the structure of the handrail mechanism.

As shown in fig. 11 to 14, the stairway elevator further comprises a handrail mechanism disposed on the rail car frame 2, the handrail mechanism comprising a handrail connecting rod 41 movably disposed on the rail car frame 2, a handrail 42 disposed outside the housing 1, and a driving member 35 driving the handrail 42 to move the connecting rod 41. One end of the armrest link 41 extends outside the housing 1 and is connected to the armrest 42. The drive member 35 drives the armrest 42 up and down relative to the housing 1. In the technical scheme, the rail car frame 2 is movably provided with a handrail connecting rod 41, the movable arrangement can be a sliding arrangement, a hinged arrangement and the like, and one end part of the handrail connecting rod 41 extends out of the shell 1 and is connected with the handrail 42. The driving member 35 can drive the handrail connecting rod 41 to move relative to the track frame 2, so that the handrail 42 can be raised and lowered relative to the housing 1.

Based on the structure, the scheme has the following technical effects:

1. the height of the handrail 42 extending out from the housing 1 can be larger than the height of the existing handrail 42 from the housing 1, so that the height of the housing 1 can be relatively reduced, thereby reducing the occupied space of the corridor.

2. When the corridor elevator runs in a no-load state, the handrail 42 can run close to the shell 1, so that the possibility that the handrail 42 is touched by people by mistake can be reduced.

On the basis that the armrest 42 can be lifted and lowered relative to the housing 1, one end of the armrest link 41 is hinged to the rail car frame 2, and the driving member 35 drives the armrest link 41 to rotate along the hinged end thereof, so that the armrest 42 is lifted and lowered relative to the housing 1. When the armrest 42 is at the lowest position, the armrest 42 is axially substantially parallel to the upper end surface of the housing 1. The axial inclination angle of the armrest 42 at the highest position is smaller than the axial inclination angle of the armrest 42 at the lowest position. In the above technical solution, the handrail connecting rod 41 is connected to the track frame 2 in an articulated manner, and the driving member 35 drives the handrail connecting rod 41 to rotate along the articulated end thereof. The advantage of using a hinged connection to achieve lift over a sliding lift is that the axial tilt angle of the armrest 42 changes as the height position of the armrest 42 changes.

As described in the background art, in the conventional solution, the body of the handrail 42 is substantially parallel to the housing 1, and in this state, the body of the handrail 42 is inclined, and when the user is going down in the stairway elevator, the lower half section of the body of the handrail 42 held by the user is relatively low and inclined, and the wrist posture of the user is very uncomfortable. In this embodiment, when the armrest 42 is at the lowest position, the armrest 42 is axially substantially parallel to the upper end surface of the housing 1. The axial inclination angle of the armrest 42 at the highest position is smaller than the axial inclination angle of the armrest 42 at the lowest position. When the corridor elevator runs, as the handrail 42 is at the highest position, the axial inclination angle of the handrail 42 is smaller, namely the lower half section of the handrail 42 is obviously lifted. When the user takes the corridor elevator and goes down, the lower half section of the hand-held handrail 42 is obviously lifted, so that the user can hold the hand more suitably, and the posture is more natural.

The driving part 35 is directly or indirectly connected with a driving connecting rod 43, and the driving connecting rod 43 is coaxially hinged with the handrail connecting rod 41. The armrest link 41 is mounted on the active link 43 by gravity, specifically, the active link 43 is provided with a limit stop 44, and the armrest link 41 can be mounted on the limit stop 44 on the active link 43. In addition, the track frame 2 is provided with a limit stop piece 21 for limiting the lifting height of the handrail connecting rod 41. In this embodiment, the armrest link 41 can be mounted on the limit stop 44 of the active link 43, so that the armrest link 41 and the armrest 42 can be lifted and lowered passively by the lifting and lowering of the active link 43. The armrest link 41 and the armrest 42 passively ascend and descend by following the ascending and descending of the active link 43 in the absence of an external force, but the armrest link 41 and the armrest 42 may ascend and descend by itself by separating from the ascending and descending of the active link 43 in the absence of an external force. The limiting blocking piece 21 is arranged on the rail car frame 2, and the lifting height of the handrail connecting rod 41 is limited by the limiting blocking piece 21, so that the handrail 42 can be prevented from being forcibly pulled by external force, and the handrail 42 is prevented from being lifted too high.

Under the scheme, the driving part 35 drives the driving connecting rod 43 to move relative to the track frame 2, and drives the handrail connecting rod 41 and the handrail 42 connected with the handrail connecting rod to lift. In this embodiment, the output end of the driving member 35 is connected to the driving link 43, and the armrest link 41 is supported by gravity on the driving link 43. That is, the driving member 35 drives the driving link 43 to move up and down, and the handrail link 41 and the handrail 42 connected thereto are simply mounted on and rest on the driving link 43. The active link 43 is passively lifted as it is lifted. In this embodiment, on one hand, the driving member 35 can control the armrest link 41 and the armrest 42 connected thereto to ascend and descend, and on the other hand, the armrest link 41 and the armrest 42 connected thereto can also ascend and descend by itself under the action of external force. When the corridor elevator is in idle operation, if foreign matters are caught between the handrail 42 and the housing 1, the handrail 42 can be lifted during operation. Therefore, the structure can not cause the problem of finger clamping damage, and the safety is higher.

3, realizing the linkage of the handrail 42 and the pedal 32.

In the above-mentioned technical solution, the driving member 35 of the armrest 42 mechanism and the driving member 35 of the pedal mechanism may be independent of each other. But in this embodiment the step 32 and the armrest 42 may be linked. As shown in fig. 11-14 in particular, the drive member 35 that drives the handrail link 41 is the drive member 35 in a pedal drive. When the pedal 32 is folded relative to the rail car frame 2, the armrest 42 is at the lowest position relative to the housing 1. When the step 32 is folded out relative to the rail car frame 2, the armrest 42 is in the uppermost position relative to the housing 1. In this technical solution, the pedal 32 and the handrail 42 are driven by the same driving member 35 to realize linkage, and have the following two advantages:

1. the actions of the handrail 42 and the steps 32 can be completed only by a single driving part and a single control part in the step driving device, compared with the case that the handrail 42 and the steps 32 adopt the driving part and the control part respectively, the cost is reduced, and the failure rate is reduced.

2. Since the pedal drive device drives the handrail 42 and the pedals 32 in synchronization, the actions of the handrail 42 and the pedals 32 are linked. When the stairway elevator is in operation, the steps 32 in the step mechanism are in the flipped-out state, and the handrail 42 is at the highest position, and at this time, the user can ride on the steps 32 and hold the handrail 42. When the stairway elevator is not in operation or is in no-load operation, the handrail 42 is at the lowest position when the steps 32 are in the collapsed state.

In the specific embodiment, as shown in the figure, the driving link 43 is directly arranged on the output end of the driving part 35, the pulling component further comprises a conversion frame 22 with one end hinged on the track frame 2, the conversion frame 22 is connected with the driving link 43 for linkage, and the spring 36 and the spring support thereof are arranged between the conversion frame 22 and the driving link 43. Of course, instead of the solution shown in the figures, the spring 36 and its spring support can also be mounted between the switching frame 22 and the pedal 32.
