Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an intelligent elevator. Background Art

[0002] Construction elevators (hereinafter referred to as elevators) are commonly used elevator equipment on construction sites, mainly used to transport personnel and construction materials such as stone, concrete, and decorative materials (hereinafter referred to as materials). In fact, since there is a gap between the bottom sill of the car and the bottom sill of the floor door, according to national standards, the gap of the elevator sill shall not be greater than 35mm. When the elevator is in use, it is common for staff to accidentally drop some materials into the gap of the elevator sill. A small part of the material that is about the same size as the gap of the elevator sill may be stuck in the gap of the elevator sill. When the elevator door is closed, the material will be stuck tighter in the gap of the elevator sill, and the elevator door cannot be closed, making the elevator unusable and requiring professional personnel to clean it up, affecting the construction progress. Summary of the invention

[0003] Therefore, in order to solve the above-mentioned problems, the present invention proposes an intelligent elevator, which can effectively protect the gap of the elevator sill when in use, and prevent materials from falling into the gap of the elevator sill and causing the elevator to be unusable.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] refer to Figures 1 to 11The present embodiment provides an intelligent elevator, comprising a car 1, a track mechanism 2 arranged at the upper and lower sides of the front end of the car 1, a first elevator door 3 slidably arranged on one side of the track mechanism 2, a second elevator door 4 slidably arranged on the other side of the track mechanism 2, a first hinged member 5 rotatably arranged on the left and right sides of the bottom of the car 1, a rotating support plate 6 arranged between the first hinged members 5, a second hinged member 7 spaced apart from the first hinged member 5, a rotating rod 8 rotatably arranged on the second hinged member 7, a connecting rod 9 arranged between the rotating rod 8 and the rotating support plate 6, a torsion spring 10 arranged on the outer side of the second hinged member 7 and used to rotate the rotating rod 8, a first motor 11 for driving the rotating rod 8 to rotate, an inclination sensor 12 arranged on the rotating support plate 6 for detecting the rotation angle of the rotating support plate 6, and a speaker device 13 arranged in the car 1, wherein the rotating support plate 6 is arranged in the car 1 near the first elevator door 3.

[0029] It should be noted that the inclination sensor 12 should be installed on the side of the rotating support plate 6 so that it is not easy to be pressed by people and / or objects during daily use. The housing of the inclination sensor 12 itself also has a certain degree of pressure resistance.

[0030] When the first elevator door 3 and the second elevator door 4 are fully opened, the first motor 11 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the rotating support plate 6 to rotate through the connecting rod 9 until the rotating support plate 6 is attached to the bottom of the car 1. At this time, the inclination sensor 12 detects that the inclination angle of the rotating support plate 6 is 0°±1° (the error range of the inclination sensor 12 is ±1°). The rotating support plate 6 can block the elevator sill gap between the bottom sill of the car and the bottom sill of the floor door, and then people and / or objects can enter and exit the car 1, which can effectively prevent stones, concrete, decorative materials and other materials from falling into the elevator sill gap.

[0031] When the first elevator door 3 and the second elevator door 4 need to be closed, the grating sensor (built-in, not shown in the figure) between the first elevator door 3 and the second elevator door 4 does not detect any person and / or object blocking it. Before the first elevator door 3 and the second elevator door 4 are closed, the first motor 11 is controlled to be powered off. If at this time, materials such as stones, concrete, decorative materials exceeding a certain weight fall onto the top surface of the rotating support plate 6, the torsion spring 10 will not be able to drive the rotating support plate 6 to rotate. At this time, the inclination sensor 12 detects that the inclination angle of the rotating support plate 6 is 90°±1°. The inclination sensor 12 does not detect that the rotating support plate 6 has rotated into place. The speaker device 13 in the car 1 will emit a buzzer warning to prompt the staff to clean the materials on the support plate 6 to prevent the elevator from being stuck in the gap of the elevator sill and making the elevator unusable. Most of the time, there is no or only a small amount of materials such as stones, concrete, and decorative materials falling onto the top surface of the rotating support plate 6. Under the action of the torsion spring 10, the rotating support plate 6 will automatically rotate to its position, and the stones, concrete, and decorative materials will be pushed into the car 1, and then cleaned by the cleaning device 25. When the inclination sensor 12 detects that the rotating support plate 6 rotates to its position, the first elevator door 3 and the second elevator door 4 can be controlled to close. The setting of the rotating support plate 6 does not affect the normal use of the elevator.

[0032] The car 1 is provided with a third hinged member 14 at intervals near the second hinged member 7, a clamping plate 15 is hingedly provided on one side of the third hinged member 14, a limiting column 16 is provided on the top of the rotating rod 8, a circular hole 17 for inserting the limiting column 16 is provided on the top of the clamping plate 15, an elastic member 18 is provided between the clamping plate 15 and the third hinged member 14, a driving mechanism 19 for driving the clamping plate 15 to rotate is provided on the third hinged member 14; a guide plate 20 is provided on the top of the clamping plate 15.

[0033] When the rotating rod 8 rotates, the limiting column 16 at the top enters the circular hole 17 at the top of the clamping plate 15 through the guide plate 20. Since there is an elastic component 18 between the clamping plate 15 and the third hinge member 14, the rotating support plate 6 will not be able to flip over when stepped on or pushed by external force, thereby preventing the rotating support plate 6 from rotating due to human stepping on it. When the rotating support plate 6 needs to be rotated, the driving mechanism 19 drives the clamping plate 15 to push to the side away from the third hinge member 14, and the circular hole 17 at the top of the clamping plate 15 is separated from the limiting column 16 at the top of the rotating rod 8. The rotating rod 8 will rotate to flip the rotating support plate 6, and the structure is stable.

[0034] The driving mechanism 19 is a driving cylinder hinged to the clamping plate 15 .

[0035] A camera 23 is provided on the top of the car 1, a pyroelectric sensor 24 is provided in the car 1, and cleaning devices 25 are provided on both sides of the inner wall of the car 1. The cleaning device 25 includes a cleaning device support seat 501 provided on the front and rear sides of the car 1, a worm 502 rotatably provided on the front and rear sides of the cleaning device support seat 501, a second motor 503 for driving the worm 502 to rotate, a guide frame 504 fixed on the front and rear sides of the cleaning device support seat 501, a screw 505 rotatably provided in each guide frame 504, a worm wheel 506 fixed at the bottom of the screw 505 and meshing with the worm 502, a slider structure 507 slidably provided in the guide frame 504, a cleaning device frame 508 rotatably provided between the slider structures 507, a guide gear 509 fixed on one side of the cleaning device frame 508, and a guide gear 509 provided on the cleaning device support seat 501 and meshing with the guide gear 509. The cleaning device frame 508 includes a toothed plate 510, a guide rail mechanism 511 provided on the front and rear sides of the cleaning device frame 508, a driving column 512 provided on one side of the cleaning device frame 508, a cleaning device housing 513 slidably provided on the guide rail mechanism 511, long plates 514 provided at the bottom of both sides of the cleaning device housing 513, a driving shaft 515 provided between the long plates 514, a brush structure 516 provided on the outside of the driving shaft 515, a driving gear 517 provided on one side of the driving shaft 515 and meshing with the driving column 512, a third motor 518 provided at the bottom of the long plate 514 and used to drive the driving shaft 515 to rotate, a negative pressure exhaust hood 519 provided on one side of the cleaning device housing 513, and a cleaning scraper 520 provided at the bottom of the negative pressure exhaust hood 519, the middle part of the slider structure 507 is screwed with the screw rod 505, and the two sides of the guide gear 509 are horizontally spaced with latch teeth 521.

[0036] Before use, the negative pressure exhaust hood 519 is connected to an external negative pressure pipe (not shown in the figure), and can be set to a certain time period (for example, 00:00-1:00). When the camera 23 and the pyroelectric sensor 24 detect that there is no one in the car 1, the second motor 503 drives the worm 502 to rotate, and the rotation of the worm 502 drives the screw rod 505 to rotate. The screw rod 505 drives the cleaning device frame 508 to move downward through the slider structure 507. During the downward movement of the cleaning device frame 508, the guide gear 509 on one side contacts the tooth plate 510 and drives the cleaning device frame 508 to rotate. The cleaning device frame 508 will rotate to a position that is flush with the floor of the car 1, and then the latching tooth 521 on the guide gear 509 will fit with the bottom of the tooth plate 510, and the cleaning device frame 508 will keep sliding downward horizontally until the brush structure 516 inside the cleaning device frame 508 fits on the floor inside the car 1, and the external negative pressure pipe will start to suck air. After completion, the third motor 518 drives the driving shaft 515 to rotate, and the outer brush structure 516 is driven to rotate during the rotation of the driving shaft 515, and the driving gear 517 on one side of the driving shaft 515 rotates at the same time. The moving column 512 is meshed, and the brush structure 516 moves toward the middle of the car 1 during the rotation process to complete the cleaning of the floor. At the same time, the negative pressure exhaust air hood 519 on one side absorbs and cleans the floor of the car 1. Since the cleaning scraper 520 is in contact with the ground, the surface water stains will be pushed to one side. The negative pressure of the negative pressure exhaust air hood 519 is large, and the water stains and materials scraped by the cleaning scraper 520 are absorbed by the external negative pressure pipe to complete the simple cleaning. Then the brush structure 516 passes again for cleaning. After the cleaning device housing 513 moves back and forth left and right to return to the initial position, the third motor 518 stops running, and the second motor 50 3 drives the worm 502 to rotate in the opposite direction, and the rotation of the worm 502 drives the slider structure 507 and the cleaning device frame 508 to rise upward. When it moves to the top position, the guide gear 509 on one side of the cleaning device frame 508 contacts and rotates with the tooth plate 510, and the guide gear 509 drives the cleaning device frame 508 to rotate clockwise, so that the cleaning device frame 508 remains parallel to the inner wall of the car 1. The brush structure 516 and the cleaning scraper 520 after rotation are close to the side wall of the car 1 and will not contact people entering and exiting the elevator. It is hygienic to use, and the cleaning device 25 can be raised and lowered and rotated, so it occupies a small space. When the cleaning device 25 is working, the elevator is suspended.

[0037] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
