The signal wire A of a range sensor is connected with the signal input part of processor, and signal output part and the hydraulic station of processor connect
Connect, each hydraulic line B and each oil cylinder of hydraulic station are respectively communicated with.
Sled is dragged in the self-leveling type movement of the utility model, is further characterized in that：
The structure of every group of adjustable support leg is, including inner cylinder and outer barrel two parts, and correspondence is opened between inner cylinder and outer barrel
There is multigroup pin shaft hole, with dragging sled main body lower face to be fixedly connected, the inner cylinder lower end of adjustable support leg connects for the outer barrel upper end of adjustable support leg
It is connected to bearing；With dragging sled main body lower face to be fixedly connected, the piston rod end of oil cylinder is cut with scissors downwards the cylinder base of oil cylinder with bearing
Connect.
The inner cylinder lower end of every group of adjustable support leg connects a bearing, total of four bearing；Or in front and back position
One bearing is set respectively, altogether two bearings.
The range sensor uses mechanical sensor.
The range sensor uses wireless type sensor.
The beneficial effects of the utility model are the mounting distance sensors at each oil cylinder, for detecting each oil cylinder
The length that piston rod stretches out, that is, detect the elevated height of each oil cylinder；After detected value is delivered to processor by range sensor, by
Processor judges whether the nonsynchronous phenomenon of oil cylinder；When some oil cylinder is asynchronous, processor control hydraulic station cuts off it
The fuel feeding of its oil cylinder, and nonsynchronous oil cylinder is individually adjusted；It is extensive after the piston rod extension elongation of all oil cylinders is consistent
The multiple fuel feeding to all oil cylinders, stretches out, all jackings can be achieved in once-through operation so as to fulfill the synchronization of all cylinder piston rods
The synchronous operation of oil cylinder, the automatic leveling of sled is dragged so as to fulfill movement.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1, Fig. 2, the structure of the utility model is, including four groups of adjustable support legs 1 and four oil cylinders 2, is led dragging sled
4 lower face corner location of body sets one group of adjustable support leg 1 and an oil cylinder 2 respectively, drags sled 4 lower face of main body to be installed by front position
There are two groups of axle aggregates 7, drag sled 4 lower face back edge position of main body to be provided with socket 8；
The structure of every group of adjustable support leg 1 is, including inner cylinder and outer barrel two parts, and correspondence is provided with multigroup between inner cylinder and outer barrel
Pin shaft hole, with dragging 4 lower face of sled main body to be fixedly connected, the inner cylinder lower end of adjustable support leg 1 is connected with for the outer barrel upper end of adjustable support leg 1
Bearing 5；With dragging 4 lower face of sled main body to be fixedly connected, the piston rod end of oil cylinder 2 is cut with scissors downwards the cylinder base of oil cylinder 2 with bearing 5
Connect；A bearing 5, total of four bearing 5 are connected in the inner cylinder lower end of every group of adjustable support leg 1, or is set respectively in front and back position
A bearing 5 is put, is exactly two bearings 5 altogether；
Range sensor 6 is separately installed with the cylinder barrel of each oil cylinder 2, for detecting the cylinder barrel and bearing 5 of oil cylinder 2
The distance between (or ground)；In addition, drag 4 lower face of sled main body that processor 3, the signal wire A of each range sensor 6 are installed
Signal input part with processor 3 is connected, and the signal output part of processor 3 is connected with hydraulic station 9, each liquid of hydraulic station 9
Pressure pipeline B is respectively communicated with each oil cylinder 2.
Range sensor 6 can also be installed on oil cylinder on or adjustable support leg on or other positions, range sensor 6 use machine
Tool formula sensor or wireless type sensor.
With reference to Fig. 2, the operation principle of the utility model is,
1) during lifting operation,
First, each oil cylinder 2 jacks at the same time, and the piston rod of each oil cylinder 2 stretches out at the same time, and sled main body 4 is dragged in upward lifting, together
When each adjustable support leg 1 inner cylinder extended downwardly under the action of 5 gravity of gravity and bearing, reach patch position after, each
Axis pin is penetrated in pin shaft hole between the inner cylinder and outer barrel of a adjustable support leg 1, makes the inner cylinder of each adjustable support leg 1 opposite with outer barrel
It is fixed, all 2 pressure of oil cylinder are then discharged, the weight for dragging sled main body 4 and its transportation equipment is undertaken by adjustable support leg 1；
Then, the height number detected is delivered in processor 3 by each range sensor 6, is by the judgement of processor 3
It is no that there are each 2 nonsynchronous phenomenon of oil cylinder.When the piston rod extension elongation of some oil cylinder 2 is asynchronous with other oil cylinders 2, place
Reason device 3 judges which oil cylinder 2 is asynchronous by the error detection value situation of each range sensor 6, and control hydraulic station 9 is closed
Individually it is adjusted to the fuel feeding of other oil cylinders 2, and to nonsynchronous oil cylinder 2.In the piston rod extension elongation one of all oil cylinders 2
After cause, recover to all oil cylinders 2 while fuel feeding.Therefore, the synchronous mesh of all oil cylinders 2 can reach by Primary regulation operation
, realize the self-level(l)ing for dragging sled main body 4.
2) during movement,
First all oil cylinders 2 are slightly jacked so that the bearing 5 of each 1 lower end of adjustable support leg is hanging, while by two groups of sockets
8 are connected with tractor；The axis pin between the inner cylinder and outer barrel of each adjustable support leg 1 is removed again；Then all 2 pressure releases of oil cylinder, are received
Fixed again with axis pin after returning adjustable support leg 1 so that two groups of axle aggregates 7 and socket 8 undertake the overall weight for dragging sled main body 4；
Integral transporting is realized finally by 8, two groups of axle aggregates 7 of tractor and socket.
