Embodiment
Make further specifically below by specific embodiment, and with reference to accompanying drawing, the technical scheme new to this implementation
It is bright.
As shown in figure 1, a kind of dolly for being capable of automatic lifting, including：Base 1, the base 1 are provided with first support 3
With second support 4, first support 3 is flexibly connected with second support 4 in infall by rotating shaft 5, first support 3 and second support
4 are provided with workbench 2, and described one end of base 1 is fixed with pull lever 7, fixed between the pull lever 7 and second support 4
Provided with cross bar（It is not drawn into figure）, the cross bar is rotatablely connected with hydraulic cylinder rotating shaft 61, the hydraulic stem and first of the hydraulic cylinder 6
The intermediate rotary shaft 5 of support 3 and second support 4 is rotatablely connected, in addition to passes through magnetic valve（It is not drawn into figure）It is connected with hydraulic cylinder 6
PLC（It is not drawn into figure）, the PLC and vertical first sensor 11 and the second sensor being fixed on side by side in pull lever 7
12 connections, when the first sensor 11 detects that there is object in front, PLC is done by the hydraulic stem of solenoid valve control hydraulic cylinder 6
Contractile motion, the second sensor 12 detect front when not having object, the hydraulic pressure that PLC passes through solenoid valve control hydraulic cylinder 6
Bar does stretching motion.
Wherein, first sensor 11 is set, when first sensor 11 detects that there is object in the front of first sensor 11,
Signal data is passed to PLC, and PLC does contractile motion by the hydraulic stem of solenoid valve control hydraulic cylinder 6, declines workbench 2.
Further, second sensor 12 is set, when second sensor 12 detects that the front of second sensor 12 does not have
During object, signal data is passed to PLC, and PLC does stretching motion by the hydraulic stem of solenoid valve control hydraulic cylinder 6, makes workbench 2
Rise.
Specifically, when blanking works, first sensor 11 is highly set to highly consistent with platform of blanking, first
Sensor 11 is arranged on the top of second sensor 12, and spacing distance is less than height of materials.Now second sensor 12 detects not
To objects in front signal, magnetic valve is controlled to move hydraulic cylinder 6 by PLC, the workbench 2 under the motion effect of hydraulic cylinder 6
The height of second sensor 12 is risen to, after second sensor 12 detects that there is object in front, hydraulic cylinder 6 is stopped, work
The height of platform 2 now is the height that second sensor 12 is set, highly consistent with platform of blanking.When blanking, material is placed
On workbench 2, now first sensor 11 detects that there is object signal in front, controls magnetic valve to make hydraulic cylinder 6 by PLC
Motion, workbench 2 drop to whole height of the material on workbench 2 less than hydraulic cylinder after the height of first sensor 11
6 stop motions, now the top surface of material flushed with lower charge level.Using dolly as the loading-unloading vehicle after blanking, can be always maintained at
The height of material top surface on the workbench 2 or dolly of dolly and platform of blanking it is highly consistent, reduce working strength.
When feeding works, the height of second sensor 12 is set above to the position of the material of top on workbench 2
Put, now the bottom of the material of top and material loading platform are highly consistent on workbench 2, are taken away when by the material of top
Afterwards, second sensor 12, which can't detect front, object signal, controls hydraulic cylinder 6 to move by PLC, workbench 2 rises to
The stop motion of hydraulic cylinder 6 afterwards concordant with second sensor 12 at the top of second material, the now bottom of second material and blanking
Podium level is consistent.Using dolly as feeding tool car, the height of materials that can be always maintained on dolly is consistent, facilitates feeding
Work.
Wherein, the one end of first support 3 is rotatablely connected with the first rotating shaft 32 being fixed on base 1, and the other end is flat with work
Platform 2 is flexibly connected by the first guide wheel 31；Described one end of second support 4 and 42 turns of the second rotating shaft being fixed on workbench 2
Dynamic connection, the other end are flexibly connected with base 1 by the second guide wheel 41, and the structure composition can guarantee that workbench 2 smoothly rises
Drop.
Wherein, first sensor 11 and second sensor 12 pass through fastener（It is not drawn into figure）Pull lever 7 is fixed on to block
In groove 10, further, first sensor 11 and second sensor 12 can move along the direction of neck 10, by the way that first is passed
The position of sensor 11 and second sensor 12 changes the material that can be directed to different size, adds the practicality of dolly.
Wherein, base bottom is provided with four universal wheels 9 for carrying locking mechanism, in use by by universal wheel 9
Locking, dolly can be made to rest on certain for a long time, ensure the stability in the course of work.
Embodiment described above is a kind of preferable scheme of the present invention, not the present invention is made any formal
Limitation, there are other variants and remodeling on the premise of without departing from the technical scheme described in claim.
