B1 hydraulic fluid port be connected respectively with the E mouth of the B of two-bit triplet solenoid valve 5 mouth and 2/2-way solenoid valve 4.The main setting of multi-way valve 3 four
A hydraulic fluid port, when left side spool works, A1 hydraulic fluid port and B1 hydraulic fluid port are opened, and A2 hydraulic fluid port and B2 hydraulic fluid port are closed；When right side spool works, A1
Hydraulic fluid port and B1 hydraulic fluid port are closed, and A2 hydraulic fluid port and B2 hydraulic fluid port are opened.
The working principle of the utility model is as follows:
(1) left side Shift cylinder 1 moves left and right:
The left side spool of main multi-way valve 3 works, and supplies Q mouthfuls of the rod chamber and nothing of left side Shift cylinder 1 by pipeline respectively
P mouthfuls of rod cavity, moving left and right for left side Shift cylinder 1 is realized, so that right side pallet fork be driven individually to move left and right.It is specific as follows:
When the A1 hydraulic fluid port of main multi-way valve 3 is fuel-displaced, high pressure oil enters Q mouthfuls of rod chamber of left side Shift cylinder 1 by pipeline,
Move to left the piston rod of left side Shift cylinder 1, at this point, P mouthfuls of the rodless cavity of left side Shift cylinder 1 is fuel-displaced, high pressure oil passes through two
The A mouth of three-way magnetic valve 5, the B mouthfuls of B1 hydraulic fluid ports for flowing back into main multi-way valve 3, right fork can be realized and be moved to left；
When the B1 hydraulic fluid port of main multi-way valve 3 is fuel-displaced, high pressure oil enters a left side after the B of two-bit triplet solenoid valve 5 mouth, A mouthfuls
P mouthfuls of the rodless cavity of side Shift cylinder 1 moves to right the piston rod of left side Shift cylinder 1, at this point, left side Shift cylinder 1 has chamber bar
Q mouthfuls fuel-displaced, and high pressure oil is back to the A1 hydraulic fluid port of main multi-way valve 3, and right fork can be realized and be moved to right.
(2) right side Shift cylinder 2 moves left and right:
The right side spool of main multi-way valve 3 works, and supplies N mouthfuls of the rodless cavity of right side Shift cylinder 2 by pipeline respectively and has
M mouthfuls of rod cavity, moving left and right for right side Shift cylinder 2 is realized, so that left side pallet fork be driven individually to move left and right.It is specific as follows:
When the A2 hydraulic fluid port of main multi-way valve 3 is fuel-displaced, high pressure oil enters M mouthfuls of rod chamber of right side Shift cylinder 2 by pipeline,
Move to right the piston rod of right side Shift cylinder 2, at this point, N mouthfuls of the rodless cavity of right side Shift cylinder 2 is fuel-displaced, high pressure oil passes through pipeline
The B2 hydraulic fluid port of main multi-way valve 3 is flowed back into, left pallet fork can be realized and be moved to right；
When the B2 hydraulic fluid port of main multi-way valve 3 is fuel-displaced, high pressure oil enters N mouthfuls of rodless cavity of right side Shift cylinder 2 by pipeline,
Make left side Shift cylinder 1 piston rod move to left, at this point, right side Shift cylinder 1 have M mouthfuls of chamber bar it is fuel-displaced, high pressure oil is back to master
The A2 hydraulic fluid port of multi-way valve 3, right fork can be realized and be moved to left.
(3) left side Shift cylinder moves left and right simultaneously with right side Shift cylinder:
When the work of the left side spool of main multi-way valve 3,2/2-way solenoid valve 4 and two-bit triplet solenoid valve 5 simultaneously it is electric,
The A mouth of two-bit triplet solenoid valve is connected to C mouthfuls, and it is mobile that the high pressure oil come out from the A1 hydraulic fluid port of main multi-way valve 3 initially enters left side
The rod chamber hydraulic fluid port Q of oil cylinder 1, under the action of pressure oil, the piston rod of left side Shift cylinder 1 is moved to left, and rodless cavity oil will be from
The rodless cavity hydraulic fluid port P of left side Shift cylinder 1 is squeezed out, and after the A mouth that two-bit triplet solenoid valve 5 is reached along pipeline, passes through two three
The C mouth of three-way electromagnetic valve 5 enters the rod chamber hydraulic fluid port M of right side Shift cylinder 2, and pressure oil will push the piston of right side Shift cylinder 2
Bar moves right, and rodless cavity oil will be squeezed out from the rodless cavity hydraulic fluid port N of right side Shift cylinder 2, passes through 2/2-way solenoid valve 4
After H mouthfuls and E mouthfuls, it is back to the B1 hydraulic fluid port of main multi-way valve 3, forms a complete oil circuit, at this time left side Shift cylinder 1 and right side
Shift cylinder 2 is mobile simultaneously, to drive, left pallet fork is moved to right, right fork moves to left；
Conversely, from the B1 hydraulic fluid port of main multi-way valve 3 come out high pressure oil by 2/2-way solenoid valve 4 E mouth, H mouthfuls it is laggard
Enter the rodless cavity hydraulic fluid port N of right side Shift cylinder 2, under pressure, the piston rod of right side Shift cylinder 2 moves to left, rodless cavity oil
It will squeeze out from the rod chamber hydraulic fluid port M of right side Shift cylinder 2, after the C mouth that two-bit triplet solenoid valve 5 is reached along pipeline, pass through
The A mouth of two-bit triplet solenoid valve 5 enters the rodless cavity hydraulic fluid port P of left side Shift cylinder 1, and pressure oil will push left side Shift cylinder 1
Piston rod move right, rod chamber oil will be squeezed out from the rod chamber hydraulic fluid port Q of left side Shift cylinder 1, be back to main multi-way valve 3
A1 hydraulic fluid port, formed a complete oil circuit, at this time left side Shift cylinder 1 and right side Shift cylinder 2 simultaneously move, to drive
Left pallet fork moves to left, right fork moves to right.
The utility model has the beneficial effects that: 1) can accurately realize single pallet fork move left and right and double pallet forks it is same
Shi Yidong meets the requirement that workshop carries precision to equipment；2) more convenient, rapid and convenient is adjusted；3) the utility model
Hydraulic system can be used to the carrying higher place of status requirement.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
