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 pattern conversion hydraulic valve block.
Technical background
Three drive a kind of all-hydraulic fork truck that the four-way fork truck is present domestic contrast advanced person, are 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, so that whole forklift pipeline is 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 conversion of the all-hydraulic forklift-walking pattern of four-way and use hydraulic valve block, reduced the quantity of flexible pipe, the difficulty that has reduced assembling and keeped in repair, 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 as follows:
A kind of three drive the all-hydraulic forklift-walking pattern conversion of four-way hydraulic valve block, include block, be provided with three two-bit triplet electromagnetic valves in the block, two three position four-way electromagnetic valves, the A1 interface of the first two-bit triplet electromagnetic valve is connected with multiway valve by the A mouth of offering on the block, the B1 interface of the first two-bit triplet electromagnetic valve by 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 respectively with the first three position four-way electromagnetic valve, the A1 interface of the second three position four-way electromagnetic valve is connected, and the first three position four-way electromagnetic valve is connected with oil sump tank by the C mouth of offering on the block in the lump with the B1 interface of the second three position four-way electromagnetic valve; The second two-bit triplet electromagnetic valve, the B1 interface of the 3rd two-bit triplet electromagnetic valve is the H mouth by offering on the block respectively, the I mouth is connected to deflector B mouth, the A mouth, the A1 interface of the 3rd two-bit triplet electromagnetic valve and the D1 interface of the second three position four-way electromagnetic valve are connected to rear steering cylinder rod chamber by 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 the second three position four-way electromagnetic valve are connected to rear steering cylinder rodless cavity by the E mouth of offering on the block in the lump, the C1 interface of the 3rd two-bit triplet electromagnetic valve and the D1 interface of the first three position four-way electromagnetic valve are connected to front steering cylinder rodless cavity by the F mouth of offering on the block in the lump, and the C1 interface of the second two-bit triplet electromagnetic valve and the A1 interface of the first three position four-way electromagnetic valve is the G mouth by offering on the block in the lump.
The A that offers on the described block, B, C, D, E, F, G, H, I mouth are respectively inner thread mouth.
The present invention realizes the logical oil of hydraulic pressure centralized by the inner reasonably channels designs of valve piece, has reduced the quantity of flexible pipe.Three drive four-way forklift-walking pattern conversion its compact conformation of hydraulic valve block, and hydraulic fluid port and internal holes design fully take into account the science of hydraulic efficiency pressure system, reasonableness, the key elements such as correctness; Consider simultaneously the leglibility of hydraulic efficiency pressure system pipeline assembling, terseness has greatly reduced the required hydraulic fitting quantity of connection oil line pipe, effectively reduces the complexity of oil line pipe, has improved the conduit under fluid pressure assembling, has safeguarded terseness, comfort feature.
