Abstract
The invention discloses a hydraulic valve block for conversion of a walking mode of a three-drive four-way all-hydraulic forklift truck. The hydraulic valve block comprises a block body, wherein three two-position three-way electromagnetic valves and two three-position four-way electromagnetic valves are arranged in the block body, an interface A1 of the first two-position three-way electromagnetic valve is connected with a multi-way valve through a port A formed on the block body, and a interface B1 of the first two-position three-way electromagnetic valve is connected with an oil outlet of a pump through a port B formed on the block body. The hydraulic valve block disclosed by the invention can reduce the number of hoses, reduce difficulty in assembly and maintenance, raise the clear degree of an oil passage, reduce the difficulty in assembly and maintenance processes of an oil passage pipeline, reduce material cost and the like.
Description
Technical field
The present invention relates to the sense line field of forklift-walking module, specifically belong to a kind of three and drive four-way forklift-walking mode converting and use hydraulic valve block.
Technical background
Three to drive the four-way fork truck be present domestic more advanced a kind of all-hydraulic fork truck, is applicable to field work, and off-road capability is strong, can realize the skidding front-wheel steering, the craspedodrome rear-axle steering, and the swing of door frame, the reaches of door frame etc. are multi-functional.Because running gear and work system all adopt hydraulic efficiency pressure system, make whole fork truck pipeline complicated, assembling and maintenance difficult.In the switching process of sideways mode, pipeline is more complicated also in the craspedodrome of fork truck, so need a kind of valve piece of design, reduces the quantity of flexible pipe, improves the comfort feature of assembling and maintenance.
Summary of the invention
The objective of the invention is a kind of three and drive the all-hydraulic forklift-walking mode converting of four-way and use hydraulic valve block, reduced the quantity of flexible pipe, reduced the difficulty of assembling and maintenance, the readability of hydraulic circuit; Reduce the difficulty of oil line pipe assembling and maintenance process, product material cost etc.
Technical scheme of the present invention is following:
A kind of three drive the all-hydraulic forklift-walking mode converting of four-way uses hydraulic valve block; Include block; Be provided with three two-bit triplet electromagnetic valves, two three position four-way electromagnetic valves in the block; The A1 interface of the first two-bit triplet electromagnetic valve is connected with multiway valve through the A mouth of offering on the block; The B1 interface of the first two-bit triplet electromagnetic valve through the B mouth offered on the block with pump hydraulic fluid port and be connected, the C1 interface of the first two-bit triplet electromagnetic valve is connected with the A1 interface of first three position four-way electromagnetic valve, second three position four-way electromagnetic valve respectively, first three position four-way electromagnetic valve is connected with oil sump tank through the C mouth of offering on the block with the B1 interface of second three position four-way electromagnetic valve in the lump; The B1 interface of the second two-bit triplet electromagnetic valve, the 3rd two-bit triplet electromagnetic valve is connected to deflector B mouth, A mouth through H mouth, the I mouth of offering on the block respectively; The A1 interface of the 3rd two-bit triplet electromagnetic valve and the D1 interface of second three position four-way electromagnetic valve are connected to back steering cylinder rod chamber through the D mouth of offering on the block in the lump; The A1 interface of the second two-bit triplet electromagnetic valve and the C1 interface of second three position four-way electromagnetic valve are connected to back steering cylinder rodless cavity through the E mouth of offering on the block in the lump; Steering cylinder rodless cavity before the C1 interface of the 3rd two-bit triplet electromagnetic valve and the D1 interface of first three position four-way electromagnetic valve are connected to through the F mouth of offering on the block in the lump, the C1 interface of the second two-bit triplet electromagnetic valve and the A1 interface of first three position four-way electromagnetic valve is the G mouth through offering on the block in the lump.
