The sensor adopts one or more of an acceleration sensor, an angular velocity sensor and an angular acceleration sensor. The type of the sensor is determined according to the installation environment of the elevator.

[0059] In this embodiment, the posture adjustment method is as follows:

[0060] (1) Set the running curve

[0061] As shown in Figure 8 and Figure 9 , the car generally does not need to be adjusted in posture on the main track, and mainly needs to be adjusted in posture when switching the main track, in the switching track, and in the front and rear connecting track sections. Therefore, the running curve of the complete path of the car posture adjustment contains a pre-swing response stage - a return-to-vertical stage - a return-to-vertical arc track running stage - an over-swing response stage - a return-to-vertical stage - a return-to-vertical inclined track running stage (only when there is an inclined track) - a pre-swing response stage - a return-to-vertical stage - a return-to-vertical arc track running stage - an over-swing response stage - a return-to-vertical main track running stage.

[0062] The pre-swing response stage is to perform a pre-action of the execution element 6 before the car starts to enter the arc track of the switching track, that is, the pre-swing starting point starts before the entering arc track point P, and the car is pre-rotated (i.e., rotated outward of the arc) by a small angle θ 预 , to generate an excessive centripetal force when entering the curve, so as to achieve a more stable track switching operation and better comfort. The swing angle is preferably less than 15°.

[0063] The return-to-vertical stage is the process of the elevator returning to the vertical state after the pre-swing stage ends, that is, the angle is returned from θ 预 to the vertical 0°.

[0064] The over-swing response stage is to perform an over-action of the adjustment structure after the car exits the arc track of the switching track, that is, the over-swing ending point should end after the exiting arc track point Q, and the car is again rotated (i.e., rotated outward of the arc) by a small angle θ 过 , to generate a lagging centripetal force when exiting the curve, so as to achieve a more stable track switching operation and better comfort. The swing angle is preferably less than 15°.

[0065] The running curve S of the execution element 6 is determined according to the included angle θ of the switching track and the main track, the instantaneous speed v of the car, and the distance L to be run by the car during adjustment (i.e., from the starting point to the end point of adjustment). The time t required by the S curve can be determined according to L and v; and the speed and angle of adjustment can be determined according to the time and acceleration requirements. The curve S during posture adjustment contains multiple speed change stages:

[0066] The jerk acceleration stage AB - the uniform acceleration stage BC - the deceleration acceleration stage CD - the uniform speed stage DE - the acceleration deceleration stage EF - the uniform deceleration stage FG - the deceleration deceleration stage GH.

[0067] The pre-swing response and the over-swing response increase the response time of the adjusting device, and can realize more stable track switching operation and better comfort.

[0068] When the car is running, the speed changes in the pre-swing response stage and the return stage, and the speed changes in the over-swing response stage and the return stage form an "S" path, and the "S" paths are opposite when the car passes through the two arc-shaped tracks of the same active switching track.

[0069] In order to ensure the better comfort of the human body, the balance and stability of the human body in the car, and the safety, the maximum value of the acceleration a in the running direction in the running curve S needs to be less than or equal to 1.5 m / s 2 , wherein the horizontal acceleration a x ≤0.1g n ; the jerk p is less than or equal to 0.1-0.13g / s n , a x =a*cosθ, wherein g n is the vertical acceleration; a is the acceleration in the running direction of the car.

[0070] In the embodiment, the angular acceleration of the adjusting structure is a, and the maximum value of a is the linear acceleration of the center of gravity of the human body when the car is adjusted, and R is the rotation radius of the center of gravity of the human body relative to the hinge point of the suspension and the car.

[0071] (2) Detecting the real-time running curve

[0072] The sensor of the posture detection structure detects the real-time running curve S1 of the executing element 6, detects the rotation angle, the angular velocity, the angular acceleration, and the angular jerk in the running curve S1, compares the real-time detected data with the set running curve S, and obtains the running deviation Δ.

[0073] (3) Comparing the deviation value

[0074] If the running deviation Δ is greater than the allowable deviation Δ p , the difference between the running deviation Δ and the allowable deviation Δ p is fed back to the adjusting mechanism, which is used to adjust the running of the executing element 6, so that the running deviation Δ is less than or equal to the allowable deviation Δ p , and the running curve S1 and the set curve S are basically fitted. If the running deviation Δ is less than or equal to the allowable deviation Δ p , no correction is needed. The allowable deviation Δ p is determined according to the actual situation of the car, and the safety test of the car needs to be performed after each elevator system is completed to determine the allowable deviation Δ p .

[0075] The adjusting method of the stabilizing assembly is the same as the adjusting structure.

[0076] The working process of the present application is as follows: when the car runs on the main track or switches tracks between different main tracks of different shafts, the car will rotate relative to the suspension due to gravity, at which time the push rod of the electric cylinder extends or retracts, the electric cylinder rotates relative to the car and the suspension, thereby driving the car to rotate relative to the suspension, realizing deviation compensation, and through the active thrust, the external unbalanced load is balanced with each other, so that the car is in a vertical state when turning, vertically or inclined running, and does not shake, realizing stable running.

[0077] Embodiment 2

[0078] Figure 10 And Figure 11 The second embodiment of the car posture adjusting device and adjusting method for the intelligent parallel elevator system of the present application is shown, and the difference between this embodiment and embodiment 1 is that: there is no posture adjustment in the return-to-normal phase, i.e. there is a speed change stage in the pre-swing response phase and the over-swing response phase, and there is no speed change stage in the return-to-normal phase.

[0079] Embodiment 3

[0080] Figure 12 And Figure 13 The third embodiment of the car posture adjusting device and adjusting method for the intelligent parallel elevator system of the present application is shown, and the difference between this embodiment and embodiment 2 is that: there is posture adjustment in the return-to-normal phase (bend keeping phase), but the adjustment range is not large, i.e. the angle, angular velocity and angular acceleration are adjusted for fine tuning, and the adjustment strength is gradually increased or gradually decreased. Therefore, the starting point of the over-swing response phase is not the value in the non-posture adjustment state, so as to make the posture of the car consistent with the shape of the fixed track switching as much as possible.

[0081] Other structures involved in the present application are recorded in the patent applied by the present applicant, and can be understood by combining the conventional technical means of those skilled in the art. Here, no more repeated description is made.

[0082] The above embodiments are only preferred embodiments of the present application, and do not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiments, it is not intended to limit the present application. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, without departing from the technical solution of the present application, shall fall within the protection scope of the technical solution of the present application.
