[0045] Among them, the position of installing deceleration to position sensor 41 and stop to position sensor 42 is set according to the tonnage of flat car 1, the greater the tonnage, the longer the deceleration distance, as long as flat car 1 is stopped in the set station after colliding with stop to position sensor 42, which is determined according to the brake performance of flat car 1 and station;

[0046] Among them, flexible rod on cross limiting sensor 11 triggers to position sensor 4 through collision, flat car 11 continues to travel forward, to position sensor 4 drives cross limiting sensor 11 to rotate, generates electric signal, to trigger corresponding control action (deceleration or stop), that is, cross limiting sensor 11 rotates one circle to decelerate, and rotates two circles to stop;

[0047] Through cross limiting sensor 11 and to position sensor 4 and other automatic sensing equipment, it realizes automatic to position and other functions;

[0048] Hydraulic station 3, it is installed on one side of lifting column assembly 2, and hydraulic station 3 is connected with proportional valve 24 in lifting column assembly 2, to control the synchronous lifting of each lifting column assembly 2;

[0049] And,

[0050] Electric control cabinet 5, to realize the centralized control to device, electric control cabinet 5 includes electrical element and control module.

[0051] As Figure 4 shown, the hydraulic station 3 includes a hydraulic station box, a plurality of accumulators 31 are installed in the hydraulic station box, each accumulator 31 is in communication with the hydraulic oil cylinder 26 and the proportional valve 24 in the lifting column assembly 2 through a pipeline, that is, each hydraulic oil cylinder 26 is provided with an accumulator 31, so that the hydraulic oil cylinder 26 can store a certain pressure.

[0052] Among them, the number of accumulators 31 is consistent with the number of lifting column assemblies 2.

[0053] As Figures 2-3 shown, the lifting column assembly 2 can be docked with the automatic flat car; it includes a bottom plate 21, a hydraulic lifting frame 22 and a hydraulic oil cylinder 26 are installed on the bottom plate 21, a mounting seat assembly 27 is installed on the hydraulic lifting frame 22 and slides thereon, chain wheels are installed on both sides of the extension end of the hydraulic oil cylinder 26, a chain is provided on each chain wheel and cooperates with the chain wheel, one end of the chain is connected with the mounting seat assembly 27, and the other end of the chain is connected with a connecting seat installed on the rod body of the hydraulic oil cylinder 26.

When both the cross-limiting sensor 11 and the arrival sensor 4 fail, the boss 12 hits the bump block 6, forcing the device to stop, further improving the safety performance.

[0058] Working process:

[0059] Step 1: As Figure 5 shown, the flat car carries out loading and unloading in the loading and unloading area outside the flat car placing station; when lifting is needed, the flat car carrying the materials automatically drives to the flat car placing station, and specifically as Figure 6As shown, the automatic flat car 1 receives the transfer instruction and drives to the destination station. When the cross-limiting sensor 11 and the deceleration-to-position sensor 41 in the arrival sensor 4 are triggered for the first time, a deceleration instruction is sent to the flat car 1 to slow down the speed and prepare for stable parking.

[0060] When the cross-limiting sensor 11 and the stop-to-position sensor in the arrival sensor 4 are triggered for the second time, a stop instruction is sent to it to completely stop at the destination station.

[0061] Step 2: After the system sends the lifting instruction, the pressure in the accumulator 31 is first stored, and the pressure at the oil port of the proportional valve 24 is detected. When all the oil ports of the proportional valve 24 reach the set pressure, the proportional valve 24 is opened to perform the lifting action. Due to the initial pressure and the assistance of the accumulator 31, the lifting speed of all hydraulic cylinders can be maximized to be consistent.

[0062] To prevent the occurrence of dangerous conditions such as lifting inclination caused by inconsistent lifting speed, multiple height points are set in the system. When the lifting sensor 25 of one hydraulic cylinder 26 detects that the cylinder reaches the first point, it stops and waits for the remaining hydraulic cylinders to reach the point. When all hydraulic cylinders 26 reach the point, all hydraulic cylinders 26 are started at the same time to realize synchronous lifting of the system and lifting of the flat car 11 to the working area, as shown. Figure 7

[0063] Step 3: After the work is completed, the lifting column assembly 2 lowers the flat car 1, and the flat car 1 retreats to the loading and unloading area.
