Problems solved by technology
Due to factors such as differences in vehicle tire pressure, uneven construction ground, different efficiency factors of various motors, and voltage differences caused by different cable lengths, the lift will have a height difference when it is working, and this height difference will cause it to be damaged. The lifted car is unbalanced, which may cause the hidden danger of car overturning and casualty accidents
Therefore, it is necessary to level the lifts. The prior art uses manual leveling of each lift one by one, which is time-consuming, labor-intensive, and has low efficiency and low precision.

Embodiment
[0019] When the lift is up and running, the motor reducer 1 drives the screw rod 2 to rotate, and the screw rod 2 drives the grid plate 3 to rotate. The speed detection switch 4 can detect the number of rotations of the grid plate 3 and convert it into a signal transmission Go to the lift controller 7 for calculation. When it is calculated that a lift exceeds the set range value, the operation of the lift within the set range value will be stopped, and the lift outside the range value will continue to be started. When all lifts When the lifts are all within the set range value, all lifts can continue to operate simultaneously. When this leveling process exceeds the set range value, the controller 7 will automatically stop the operation of all lifts. On the contrary, the operation flow is the same during the descending operation.

The invention discloses a movable type automatic levelling mechanical lifting machine set in the field of vehicle maintenance equipment. According to the machine set, four or more than four lifting machines are symmetrically arranged on two sides of a vehicle, each lifting machine comprises a machine body, a motor speed reduction machine and a screw rod, wherein each machine body is provided with a connecting plate which is connected with the motor speed reduction machine, and each motor speed reduction machine is connected with the screw rod. A round grating plate is fixedly connected with each screw rod below the motor speed reduction machine, a switch seat is arranged on each machine body and is provided with a rotating speed detection switch, each rotating speed detection switch is provided with two signal ends which are vertically corresponded, the peripheries of each grating plate are placed in openings of the two signal ends, the rotating speed detection switch of each lifting machine is connected with a controller through a data wire, and each controller is connected with a display panel through the data wire. The movable type automatic levelling mechanical lifting machine set has the characteristics of high safety coefficient, high precision and high efficiency.
Description
technical field [0001] The invention relates to the field of automobile maintenance equipment, more specifically, the invention relates to a mobile self-leveling mechanical lifting unit with high safety factor, precision and efficiency. Background technique [0002] At present, during automobile maintenance, generally four or more mobile lifts arranged symmetrically lift the automobile to a certain height, which is convenient for maintenance personnel to maintain under the automobile. Due to factors such as differences in vehicle tire pressure, uneven construction ground, different efficiency factors of various motors, and voltage differences caused by different cable lengths, the lift will have a height difference when it is working, and this height difference will cause it to be damaged. The lifted car is unbalanced, which may cause the hidden danger of car overturning and casualty accidents. Therefore, it is necessary to level the lifts. The prior art all adopts manual l...
