Detailed Description
The invention is described in detail below with reference to the figures and examples.
A safety protection device for an elevator door, referring to fig. 1, a controller 2 is arranged on an upper sill 9 of the elevator, and a driving mechanism is in signal connection with the controller 2, in the embodiment, the driving mechanism adopts a variable frequency motor 7, and the variable frequency motor 7 is fixedly connected with the upper sill 9 of the elevator by a support 23. A first driven wheel 8 and a second driven wheel 10 are horizontally arranged at two ends of an elevator upper sill 9, and the outer side of the first driven wheel 8 is in transmission connection with a rotating shaft of the variable frequency motor 7, so that the rotating angular speed of the first driven wheel 8 is in a proportional relation with the rotating angular speed of the rotating shaft of the variable frequency motor 7; in addition, the first driven wheel 8 and the second driven wheel 10 are connected through a belt 11, that is, when the variable frequency motor 7 works, the first driven wheel 8 is driven to rotate first, and then the first driven wheel 8 drives the second driven wheel 10 to rotate through the belt 11.
A first connecting mechanism used for being connected with the car door 1 is arranged on the belt 11 and above a connecting line of rotating shafts of the first driven wheel 8 and the second driven wheel 10; a second connecting mechanism connected with the other car door 1 is arranged on the belt 11 and below a connecting line of the rotating shafts of the first driven wheel 8 and the second driven wheel 10; wherein, first coupling mechanism and second coupling mechanism all include the belt 11 splint of being connected with belt 11, and the lower extreme fixedly connected with connecting rod 16 of belt 11 splint, the lower extreme of connecting rod 16 is connected with sedan-chair door 1. In order to reduce the load on the belt 11, a sliding rail assembly is arranged below the belt 11, and the sliding rail assembly comprises a guide rail 17 which is arranged on the elevator upper sill 9 in parallel with the belt 11 and a roller 18 which is arranged on the connecting rod 16 and is matched with the guide rail 17 in a sliding manner, so that when the belt 11 moves relatively, the roller 18 on the connecting rod 16 is driven to slide on the guide rail 17, the load on the belt 11 is reduced, and the car door 1 is easier in the moving process. When the variable frequency motor 7 rotates, the belt 11 is driven to rotate, and the two car doors 1 move in the reverse direction under the driving of the belt 11, so that the car doors 1 are opened and closed.
In addition, be provided with transmitter 3 and receiver 4 along its length direction on sedan-chair door 1, transmitter 3 and receiver 4 set up respectively on two sedan-chair doors 1, and the infrared transmitting tube of transmitter 3 and the infrared receiving tube of receiver 4 one-to-one, have the barrier in the middle of sedan-chair door 1 for infrared ray that the infrared transmitting tube transmitted can not be received by the infrared receiving tube that corresponds, receiver 4 output trigger signal to controller 2, controller 2 output control signal is in order to control inverter motor 7 to stop or reverse work.
Because the interior of the emitter 3 is composed of a plurality of infrared emission tubes at equal intervals, and an interval exists between adjacent infrared emission tubes, when an obstacle is positioned in the interval, the obstacle cannot be detected, so that a detection blind area exists; therefore, as long as the emitter 3 can move along the length direction and is greater than or equal to the interval between the adjacent infrared emission tubes, so that the infrared emission tubes can scan the interval, the existence of the blind area can be eliminated, the sliding groove 5 is formed in the car door 1, and the sliding block 6 connected with the sliding groove 5 in a sliding manner is arranged at one end, close to the car door 1, of the emitter 3 and the receiver 4 (the position of the sliding block 6 can refer to fig. 2), so that the emitter 3 and the receiver 4 can move on the car door 1 along the length direction of the car door 1. In this embodiment, the rotation center of the first driven wheel 8 and the second driven wheel 10 is fixedly connected with a first connecting rod 12, the other end of the first connecting rod 12 is hinged with a second connecting rod 13, the other end of the second connecting rod 13 is hinged with the slider 6, the structure is a crank slider 6 structure, when the first driven wheel 8 and the second driven wheel 10 rotate, the first connecting rod 12 rotates with the second driven wheel, and the second connecting rod 13 can drive the slider 6 to slide up and down in the chute 5. Referring to fig. 3, which is a graph for analyzing a sliding distance of the slider 6 in the vertical direction, it is assumed that the length of the first connecting rod 12 is L2, the length of the first connecting rod 12 is L1, the distance between the lowest point and the highest point of the slider 6 is X, and the value of X is greater than or equal to the distance between two adjacent infrared emission tubes; when the slide block 6 is at the lowest position, the first connecting rod 12 and the second connecting rod 13 are on the same straight line, and the movable end of the first connecting rod 12 is located at the middle position, at this time, the included angle between the second connecting rod 13 and the vertical direction is A1; when the slide block 6 is located at the highest position, the connection point of the second connecting rod 13 and the first connecting rod 12 is located on the extension line of the lowest position of the slide block 6 and the center of the first driven wheel 8 or the second driven wheel 10, at this time, the included angle of the second connecting rod 13 located at the highest position and the lowest position is A2, according to the sine theorem,
of these, only two unknowns, a2 and X, are available.
However, since the car door 1 moves in the sliding direction, and the length of the first connecting link 12 and the length of the second connecting link 13 are not changed, the slider 6 must be able to move in the sliding direction within the slide groove 5. The sliding grooves 5 are arranged in a sine curve mode in combination with the movement of the sliding blocks 6 in the length direction of the car door 1, and the amplitude of the sine curve is X/2. Assuming that the radius of the first driven wheel 8 and the second driven wheel 10 is R, the moving distance of the door 1 in one cycle is 2 × pi × R, and the cycle T of the curve is 2 × pi × R, which is represented on a sinusoidal curve, and if the horizontal axis is the moving direction of the door 1 and the vertical axis is the longitudinal axis, the formula of the sinusoidal curve is:
in the formula, the function curve is only related to the radius R of the first driven wheel 8 and the second driven wheel 10, and the lengths L1, L2 of the first connecting rod 12 and the second connecting rod 13. When the car door 1 moves, the sliding block 6 moves along the sliding groove 5, so that the aim of eliminating blind areas is fulfilled; meanwhile, the whole device is provided with only one driving mechanism, so that resources are saved.
In addition, since infrared rays cannot detect transparent obstacles, transparent detection sensors 14 are arranged on the belt 11 above and below a connecting line of the rotating shafts of the first driven wheel 8 and the second driven wheel 10, the transparent detection sensors 14 adopt G3-B500N sensors and are in signal connection with the controller 2, and when the car door 1 is opened to the maximum position, the transparent detection sensors 14 are located on the same vertical plane. The two transparent detection sensors 14 are arranged because the two car doors 1 can detect whether transparent obstacles exist only by moving at most one car door 1, and more space is provided to prevent the objects from being clamped; when the transparent detection sensor 14 detects that a transparent obstacle exists, a signal is sent to the controller 2, so that the controller 2 outputs a control signal to the variable frequency motor 7 to drive the car door 1 to be opened, and the safety of the elevator is improved. Moreover, the movement of the transparent detection sensor 14 is also driven by the same driving mechanism, thereby saving energy.
In addition, the elevator upper sill 9 is provided with an opening limit switch 19 located below the second driven wheel 10, and is provided with a first speed switch 21, a second speed switch 22 and a closing limit switch 20 at a time in the direction of the first driven wheel 8, and the opening limit switch 19, the first speed switch 21, the second speed switch 22 and the closing limit switch 20 are all proximity switches and are all in signal connection with the controller 2. When the connecting rod 16 moves to the position of the door opening limit switch 19, the car door 1 stops moving; when the connecting rod 16 moves to the door closing limit switch 20, the car door 1 stops moving. In order to improve the safety of the elevator, when the elevator door is closed and the speed is lower and lower, namely the connecting rod 16 moves to the first speed switch 21, the first speed switch 21 sends a signal to the controller 2 to slow down the moving speed of the car door 1; when the connecting rod 16 moves to the second speed switch 22, the second speed switch 22 sends a signal to the controller 2 to slow down the moving speed of the car door 1 again.
The working process is as follows:
when the car door 1 is in an open state, if an obstacle is placed in a detection blind area, the transmitter 3 and the receiver 4 cannot detect the obstacle, the variable frequency motor 7 drives the car door 1 to move at the moment, so that the transmitter 3 and the receiver 4 can move along the chute 5, when the first driven wheel 8 and the second driven wheel 10 rotate for a period, the transmitting pipe and the receiving pipe can both scan the detection blind area, and the aim of eliminating the blind area is fulfilled, in the process, if the obstacle is detected, the variable frequency motor 7 rotates reversely to open the door again;
in addition, when the transparent barrier is placed in the middle of the car door 1, the detection sensors respectively move towards two sides along with the closing of the car door 1, the moving distances of the car doors 1 on the two sides are added up to the maximum distance of one car door 1, and the distance of one car door 1 can be buffered, so that the anti-pinch effect is achieved; when the transparent detection sensor 14 detects a transparent obstacle, a signal is output to the controller 2 to control the motor to rotate to open the door again.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
