Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a leveling method for a lifting platform with an automatic repairing function comprises the following steps:
the sensor senses the height information of the current position of the lifting platform and transmits the height information to the control system
The control system receives height information of a lifting platform required to reach a position;
the control system outputs the height and the deceleration area required by the lifting platform and controls the lifting platform to operate;
when the lifting platform runs to a deceleration area, the lifting platform starts to decelerate;
if the load of the lifting platform is within the light load range, the lifting platform normally reaches the target height, and the layer is automatically leveled;
if the load of the lifting platform is in the heavy load range, the inertia of the lifting platform is larger than a preset critical point, the lifting platform can continue to operate when reaching the target height, after the control system receives the position information sent back by the sensor, a standby program is started, namely the lifting platform is controlled to continue to operate to a standby position with a certain height away from the target position, and then the lifting platform is controlled to return to the target height, so that the leveling is realized.
The control system processes the received instruction and various information, then makes corresponding instructions to control the operation of the whole program, the sensor collects the position information of the lifting platform and transmits the position information to the control system in time, wherein the method for collecting the position information comprises the following steps: when the lifting platform operates, the height mark collector collects height information contained in the height marks so as to determine the height of the position of the lifting platform, and after an operator inputs target position information, the control system selects corresponding preset height marks when the lifting platform is leveled according to a target floor and drives the lifting platform to move; the height mark collector collects height information contained in the height mark and transmits the information to the control system; the control system judges the height of the lifting platform through the height information acquired by the height mark acquisition device; when the height of the lifting platform approaches to the height corresponding to the target position, namely the actual height of the lifting platform reaches a deceleration area when the target floor is leveled, the lifting platform performs deceleration movement; when the position of the height mark collector corresponds to the target position, the control system controls the lifting platform to stop running to finish leveling of the lifting platform; if the lifting platform is too large in load, in a heavy load range, the lifting platform cannot be smoothly stopped at a target position due to the fact that inertia is too large, the control system receives the height marks which are collected by the height mark collector and exceed the target position, a standby program is started, the lifting platform continuously runs to a standby position with a certain height away from the target position, then the lifting platform is controlled to return to the target height, leveling is achieved, the height mark collector continuously collects the height marks in the whole process, the height of the lifting platform is timely fed back, and accurate leveling is guaranteed.
As shown in fig. 2, when the lifting platform descends, the target position is point B, point a is a deceleration starting point, point D is a standby position, when the lifting platform reaches point a and starts to decelerate, that is, point AB is a deceleration area, when the load on the lifting platform is overweight, the lifting platform cannot completely stop when reaching point B, the lifting platform continues to move downwards to point C and point B to form a height difference, at this time, the standby program is automatically started, the control system controls the lifting platform to continue to slowly move downwards to the standby position point D, and then the lifting platform is pulled back to point B again to realize leveling.
Furthermore, the lifting platform runs slowly when executing the standby program, and the conditions of dislocation and height difference during leveling are avoided.
Further, the height difference between the target position and the standby position is 0.1-0.2m, and the height difference can be set according to actual use conditions.
Further, when the lifting platform triggers the standby program, the control system sends out voice prompts to feed back to operators in time, and misoperation is avoided.
Furthermore, if the control system fails to receive the position information, the control system directly triggers a deceleration program and sends out voice warning, so that accidents are avoided.
Furthermore, the control system continuously judges the position of the lifting platform returned by the sensor, so that the speed of the lifting platform is judged and timely adjusted.
