DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 7 As shown, the present invention proposes an elevator training system with an intelligent control device, comprising: a miniature shaft 10, a floor door 90, a base 1, an elastic simulation object device 91 and an intelligent control device. The top surface of the base 1 is recessed to form a pit, the miniature shaft 10 is installed on the base 1, the miniature shaft 10 is connected to the pit, and the base 1 is a groove structure; a door is opened on the miniature shaft 10, and the door is opened and closed by the floor door 90; an elastic simulation object device 91 is installed on the base 1, and a first elastic member connected to the base 1 is installed in the elastic simulation object device 91. Under the elastic force of the first elastic member, the elastic simulation object device 91 can be kept away from the two-floor door 90, and the elastic simulation object device 91 can be kept away from the two-floor door 90. The elastic simulation object device 91 is used to simulate an object extending between two doors 90; the intelligent control device includes: a light curtain (not shown in the figure), a control box (not shown in the figure), a display (not shown in the figure) and a switch mechanism 92. The light curtain is installed on the door 90, and a switch mechanism 92 that acts on the elastic simulation object device 91 is installed on the base 1. The switch mechanism 92 is used to close when the elastic simulation object device 91 extends between the two doors 90, and the switch mechanism 92 can be kept disconnected under the elastic force of the first elastic member. One end of the switch mechanism 92 is connected to a 5V power supply, and the other end of the switch mechanism 92 is connected to the control box. The light curtain and the display are both connected to the control box.

[0025] In order to design an elastic simulation object device 91 with a simple structure, the elastic simulation object device 91 includes: a first spring 911, a pushing block 912 and a simulation block 913. The base 1 is provided with a movable groove for the pushing block 912 to slide. One end of the first spring 911 is connected to the inner wall of the movable groove, and the other end of the first spring 911 is fixed to the pushing block. A simulation block 913 is fixed to the top of the pushing block 912. The simulation block 913 is used to be inserted between two doors 90. The first spring 911 is a first elastic member. The switch mechanism 92 is located on the side of the pushing block 912 close to the door 90, and the pushing block 912 acts on the switch mechanism 92.

[0026] In order to design a switch mechanism 92 with a simple structure, the switch mechanism 92 includes: a conductive sheet 920, a first spring sheet 921 and a second spring sheet 922. The first spring sheet 921 and the second spring sheet 922 are installed at an end of the slide groove close to the floor door 90 at an interval. A conductive sheet 920 for electrically connecting the first spring sheet 921 and the second spring sheet 922 is fixed on the push block 912. The conductive sheet 920, the first spring sheet 921 and the second spring sheet 922 are all made of conductive material. The first spring sheet 921 is connected to a 5V power supply, and the second spring sheet 922 is connected to a control box.

[0027] By pushing the push block 912, the simulated object block 913 can be inserted between the two floor doors 90. When the simulated object block 913 is inserted between the floor doors 90, the switch is closed, and the control box receives the high level input by the switch mechanism 92. At the same time, the control box receives the detection signal of the light curtain. The control box is connected to the lifting drive device through the motor driver. The lifting drive device is installed on the top of the micro elevator shaft. The lifting drive device is connected to the car, and the car is opened and closed by the car door. The car is equipped with a door drive device. The door drive device drives the car door to open and close. When the car door is opened, the floor door 90 is driven to open. When the control box receives the detection signal of the light curtain, it controls the lifting drive device not to move, and also controls the door drive device to open the floor door 90. If the signal detected by the light curtain is inconsistent with the disconnection and closure of the switch mechanism 92, the display screen will show that the light curtain is damaged. At the same time, it is very likely that the floor door 90 and the car door clamp the simulated object block 913, and the car rises and falls, causing the simulated object block 913 to be cut off, thereby facilitating the observation of the hazards of light curtain damage during practical training.

[0028] The base 1 is a groove-shaped structure. A window connected to the pit is provided on the side wall of the base 1. The window is opened and closed by a window door. The window door includes: a window frame 2, a glass plate 3, a cleaning roller 4, a connecting mechanism 5, a pull rope 6 and an elastic convolution mechanism 7. The bottom end of the window frame 2 is hinged to the base 1. The window frame 2 is closed by the glass plate 3. A slide rail 20 is installed on the inner side of the window frame 2. A cleaning roller 4 is installed on the slide rail 20. Under the guidance of the slide rail 20, the cleaning roller 4 can move in the vertical direction. The cleaning roller 4 is fixed to one end of the pull rope 6. The other end of the pull rope 6 is convoluted in the elastic convolution mechanism 7. The elastic convolution mechanism 7 is installed at the bottom of the window frame 2. The cleaning roller 4 is detachably connected to the inner wall of the top of the window through the connecting mechanism 5. By setting the base 1 and the pit provided by the base 1, the pit is simulated. At the same time, a window opened and closed by the window door is provided. The glass plate 3 is provided on the window door, which facilitates the observation of the water ingress in the pit and the influence of the water ingress on the elevator car. Furthermore, a cleaning roller 4 is provided to clean the glass plate 3; the window can be opened, which also facilitates cleaning out the water in the bottom pit; an elastic convolution mechanism 7 is provided to pull the cleaning roller 4 to the bottom end of the window frame 2; a connecting mechanism 5 is provided to detachably connect the cleaning roller 4 and the window frame 2 to the base 1, and when the window door is closed, the connecting mechanism 5 positions the cleaning roller 4 at the top of the window door, thereby avoiding obstruction of vision due to forgetting to clean the inside of the window door.

[0029] In order to design a cleaning roller 4 with a simple structure and ensure that the cleaning roller 4 can pass through the glass plate 3, the cleaning roller 4 includes: a rod body 41 and two mounting shafts 40. Two mounting shafts 40 extend from both ends of the rod body 41, and each mounting shaft 40 extends into a slide rail 20. The cooperation between the slide rail 20 and the mounting shaft 40 ensures that the cleaning roller 4 moves on the specified path and that the cleaning roller 4 can pass through the glass plate 3, thereby ensuring a good cleaning effect.

[0030] In order to design a connecting mechanism 5 with a simple structure, the second elastic movable component 53 can be driven by driving a first elastic movable component 51. The connecting mechanism 5 includes: a first elastic movable component 51, a first elastic limiting component 52, a second elastic movable component 53 and a second elastic limiting component 54. The first elastic movable component 51 and the first elastic limiting component 52 are installed at the connection between a mounting shaft 40 and a stick body 41. A second elastic member is arranged in the first elastic movable component 51. The elastic force of the second elastic member can keep the first elastic movable component 51 inserted into the base 1. The first elastic limiting component 52 is used to keep the first elastic movable component 51 located in the mounting shaft 40 and the stick body 41; the second elastic movable component 53 and the second elastic limiting component 54 are installed at the top of the window. A third elastic member is arranged in the second elastic movable component 53. The elastic force of the third elastic member can keep the second elastic movable component 53 inserted into another mounting shaft 40. The second elastic limiting component 54 is used to keep the second elastic movable component 53 away from the mounting shaft 40.

[0031] The first elastic limiting assembly 52 and the second elastic limiting assembly 54 both include: a limiting pin 521 and a second spring 522, one end of the limiting pin 521 is used to act with the corresponding first elastic movable assembly 51 or second elastic movable assembly 53, the other end of the limiting pin 521 is fixed to one end of the second spring 522, and the other end of the second spring 522 is fixed to the window frame 2 or the base 1.

[0032] The first elastic movable component 51 includes: a toggle block 511, a first movable rod 512 and a fifth spring 513. The first movable rod 512 is installed in a mounting shaft 40 and a stick body 41. The first movable rod 512 can move relative to the stick body 41 and the mounting shaft 40 in a direction parallel to the stick body 41. The first movable rod 512 is fixed to one end of the fifth spring 513, and the other end of the fifth spring 513 is fixed to the inner wall of the stick body 41. The first movable rod 512 is fixed with a toggle block 511 extending out of the window frame 2. The first movable rod 512 is provided with a first limiting hole, and the first limiting hole is used for inserting a limiting pin 521 in the first elastic limiting component 52. The fifth spring 513 is a second elastic member.

[0033] The second elastic moving component 53 includes: a second moving rod 531 and a third spring 532. Moving holes for the first moving rod 512 and the second moving rod 531 to move are opened in the stick body 41 and the two installation shafts 40. The base 1 is provided with a mounting cavity connected to the window. One end of the second moving rod 531 is used to extend into the moving hole to act with the first moving rod 512. The other end of the second moving rod 531 is located in the mounting cavity and fixed to one end of the third spring 532. The other end of the third spring 532 is fixed to the inner wall of the mounting cavity. The third spring 532 is a third elastic member. The second moving rod 531 is provided with a second limiting hole for the second elastic limiting component 54 to be inserted.

[0034] In order to design an elastic convolution mechanism 7 with a simple structure, the elastic convolution mechanism 7 includes: a convolution shell 71, a convolution cylinder 72, a central axis 73 and a coil spring 74. The convolution shell 71 is installed at the bottom end of the window frame 2, and an inner cavity is installed in the convolution shell 71. The central axis 73 extends on the inner wall of the inner cavity. The convolution cylinder 72 is surrounded by the central axis 73. The convolution cylinder 72 rotates around the central axis 73 under the guidance of the inner wall of the convolution shell 71. A coil spring 74 is convoluted between the convolution cylinder 72 and the central axis 73. The inner end of the coil spring 74 is fixed to the central axis 73, and the outer end of the coil spring 74 is fixed to the convolution cylinder 72. The convolution cylinder 72 is used for convolution pull rope 6.

[0035] Working principle of window and door cleaning roller 4:

[0036] Generally, when the window door is in a closed state, one end of the first moving rod 512 extends into the base 1 under the elastic force of the fifth spring 513, and the limiting pin 521 of the first elastic limiting assembly 52 is pressed into the stick body 41, and the first limiting hole is located on the side of the first elastic limiting assembly 52 away from the second moving rod 531; under the elastic force of the third spring 532, one end of the second moving rod 531 extends into the moving hole, and the limiting pin 521 of the second elastic limiting assembly 54 is pressed into the base 1. At this time, the second limiting hole is located on the side of the second elastic limiting assembly 54 close to the first moving rod 512. At this time, the first moving rod 512 and the second moving rod 531 respectively hang the two mounting shafts 40 on the inner wall of the top of the window, thereby stabilizing the position of the cleaning roller 4.

[0037] When the window needs to be opened, the toggle block 511 is moved so that the first moving rod 512 moves into the stick body 41, and the fifth spring 513 is compressed. Since the fifth spring 513 hinders the movement of the first moving rod 512, the first moving rod 512 moves slowly. When the first limiting hole is aligned with the limiting pin 521 of the first elastic limiting assembly 52, there is enough time to realize that the elastic force of the second spring 522 decreases and the limiting pin 521 is inserted into the first limiting hole, thereby keeping the first moving rod 512 between the mounting shaft 40 and the fixing shaft 41. At the same time, the first moving rod 512 pushes the second moving rod 531 to move, and the third spring 532 is compressed. Since the third spring 532 hinders the movement of the second moving rod 531, the second moving rod 531 moves slowly. When the second limiting hole is aligned with the limiting pin 521 of the second elastic limiting assembly 54, there is enough time to achieve the elastic force of the second spring 522 to reduce the limiting pin 521 and insert it into the second limiting hole, thereby keeping the second moving rod 531 away from the mounting shaft 40 and the stick body 41. Subsequently, under the elastic force of the coil spring 74, the pull rope 6 is coiled, and at the same time, the cleaning roller 4 sweeps across the glass plate 3 to achieve cleaning.

[0038] When closing the window, first, rotate the window to the position of closing the window; then, pull the cleaning roller 4 to the top of the window, and the window frame 2 is provided with an L-shaped slide groove for the sliding block 511 to slide; then, by toggling the toggle block 511, the first moving rod 512 continues to move toward the second moving rod 531, the fifth spring 513 and the third spring 532 are both compressed, the first limiting hole and the second limiting hole are both disengaged from the limiting pin 521, and the fifth spring 513 and the third spring 532 both store a large elastic potential energy; finally, release the toggle block 511, and at the fifth spring, the locking pin 521 is unlocked. Under the elastic force of the spring 513, the first moving rod 512 is inserted into the base 1, and under the elastic force of the third spring 532, the second moving rod 531 is inserted into the moving hole in the stick body 41. Since the movement of the first moving rod 512 and the second moving rod 531 is not hindered at this time, the first moving rod 512 and the second moving rod 531 move at a faster speed, so the limit pin 521 does not have time to be inserted into the first limit hole and the second limit hole. The first limit hole and the second limit hole both pass over the corresponding limit pin 521, thereby supporting the two mounting shafts 40, thereby stabilizing the window door in a closed state.

[0039] First, in order to facilitate observation of the situation in the pit, a window door with a glass plate 3 is designed. The window door is set at the top of the pit and does not hinder the water accumulation at the bottom of the pit; then, when the water in the pit needs to be cleared after the water accumulation test, a window door with an openable window is designed; then, because the water is not clean after passing through the car, etc., splashing on the glass plate 3 will block the line of sight, so a cleaning roller 4 is designed; then, in order to facilitate cleaning of the glass plate 3, an elastic convolution mechanism 7 and a connecting mechanism 5 are designed. The connecting mechanism 5 connects the window door to the base 1 and at the same time, the cleaning roller 4 is designed. The sweeping roller 4 is hung on the top. When the window door is opened, the elastic convolution mechanism 7 can sweep the glass plate 3. When the window door is closed, the sweeping roller 4 needs to be pulled to the top of the window door so that the connecting mechanism 5 can be connected to the base 1. Then, in order to stably hang the sweeping roller 4 on the top of the window, a first elastic movable component 51 and a second elastic movable component 53 are designed to support both mounting shafts 40. Finally, by adjusting the first elastic movable component 51, the second elastic movable component 53 can be adjusted, which facilitates the adjustment.

[0040] The elevator training system with intelligent control device also includes: a vertical shaft 82 and a support mechanism 83. The vertical shaft 82 is erected on the bottom wall of the pit. The vertical shaft 82 is hinged with the support mechanism 83. The support mechanism 83 is used to limit the car from falling into the pit.

[0041] The elevator training system with an intelligent control device also includes: a driving mechanism 84, which is installed on the base 1 and is located between the supporting mechanism 83 and the window door. The driving mechanism 84 is used to drive the supporting mechanism 83 away from the car when the window door is closed, and to drive the supporting mechanism 83 to face the car when the window door is opened.

[0042] By setting the support mechanism 83, when the window door is not opened, the support mechanism 83 rotates to a position away from the car, and the support mechanism 83 does not hinder the car from descending into the pit. When the window door is opened, the support mechanism 83 rotates to a position directly opposite the car, and the support mechanism 83 hinders the car from descending into the pit, thereby avoiding safety accidents caused by the car falling when the operator opens the pit and operates, thereby improving safety protection. Furthermore, the driving mechanism 84 is designed in the present application, so that the window door can drive the support mechanism 83 to rotate, avoiding forgetting to rotate the support mechanism 83 to a position directly opposite the car after the window door is opened, and realizing the automatic driving of the support mechanism 83 to rotate during the window door opening process, and also avoiding the need to rotate the support mechanism 83, which leads to cumbersome operation, reducing the operation steps, improving the operation efficiency, and making the operation more convenient.

[0043] In order for the window door to act with the subsequent driving mechanism 84, the bottom end of the window door is hinged with the window wall, the top end of the window door is detachably connected with the window wall, and the bottom end of the window door acts with the driving mechanism 84. The top end of the window door is detachably connected with the window wall through a door lock.

[0044] In order to design a driving mechanism 84 with a simple structure and enable the driving mechanism 84 to drive the supporting mechanism 83 to rotate back and forth, the driving mechanism 84 includes: a gear ring 841, a rack 842, a movable seat 843 and a fourth elastic member 844. The supporting mechanism 83 is fixed on a rotating ring 833. The rotating ring 833 can be rotatably mounted on the vertical shaft 82. The rotating ring 833 is fixed with a gear ring 841. The gear ring 841 can mesh with the rack 842. The rack 842 is fixed to the movable seat 843. The movable seat 843 can be slidably mounted on the base 1. A fourth elastic member 844 is connected between the movable seat 843 and the base 1. An extrusion block 850 acts on the movable seat 843. The extrusion block 850 is formed by extending from the bottom end of the window door. The fourth elastic member 844 is used to keep the movable seat 843 and the extrusion block 850 in close contact.

[0045] In order to avoid damage to the extrusion block 850 and the moving seat 843 due to excessive friction when the extrusion block 850 and the moving seat 843 are in contact, the contact surface of the extrusion block 850 and the moving seat 843 is an arc surface, which extends the service life of the extrusion block 850 and the moving seat 843.

[0046] In order to design the fourth elastic member 844 with a simple structure, the fourth elastic member 844 is a fourth spring, one end of the fourth spring is fixed to the moving seat 843 , and the other end of the fourth spring is fixed to the base 1 .

[0047] In order to design a support mechanism 83 with a simple structure, the support mechanism 83 includes: a support column 831 and a rotating arm 832, one end of the rotating arm 832 is fixed to the rotating ring 833, and the other end of the rotating arm 832 is fixed to the middle of the support column 831, the top end of the support column 831 is used to support the car, and the bottom end of the support column 831 is in close contact with the bottom wall of the pit.

[0048] In order to ensure the support strength for the rotating ring 833 and avoid excessive pressure on the rotating ring 833 causing the rotating ring 833 to fall automatically, thereby ensuring that the supporting function of the supporting mechanism 83 can be implemented normally, a support ring 820 is surrounded by the outer ring of the vertical shaft 82. The support ring 820 is located below the rotating ring 833, and the lower bottom surface of the support ring 820 is in close contact with the bottom wall of the pit.

[0049] The working principle of this embodiment:

[0050] When the window door is closed, the movable seat 843 is kept in contact with the extrusion block 850 under the elastic force of the fourth elastic member 844. At this time, the end of the rack 842 away from the movable seat 843 is engaged with the gear ring 841. At this time, the support mechanism 83 is in a position away from the car and will not hinder the car from descending into the bottom pit.

[0051] When the window door is opened, the extrusion block 850 rotates with the window door, and the extrusion block 850 pushes the moving seat 843 to move toward the center of the pit. The rack 842 moves relative to the gear ring 841, and the rack 842 drives the gear ring 841 to rotate. The gear ring 841 drives the support column 831 to rotate through the rotating ring 833 and the rotating arm 832, so that the support column 831 rotates to a position opposite to the car, thereby realizing the opening of the window door, that is, the support column 831 rotates to a position that prevents the car from descending into the pit, thereby improving safety protection and protecting the operator.

[0052] During the design, firstly, in order to ensure safety during maintenance and cleaning, a support mechanism 83 and a vertical shaft 82 are set up, so that the support mechanism 83 can be rotated to a position opposite to the car to prevent the car from falling into the bottom pit, and the support mechanism 83 can also be rotated to a position away from the car during normal use; then, a driving mechanism 84 is designed, and the driving mechanism 84 acts on both the window door and the support mechanism 83, so that when the window door is closed, the support mechanism 83 can be rotated to a position opposite to the car through the driving mechanism 84, which simplifies the operation and improves the operating efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
