Abstract

The utility model discloses an auxiliary oil way valve block of a limber for a static pressure truck-mounted forklift, which comprises a valve block, wherein a plurality of connecting oil ports are sequentially arranged on a plurality of surfaces of the valve block, and a valve block is formed by forging 45 # steel through a valve block blank, and then is sequentially processed by a milling machine, a drilling machine and a clamping machine, and finally, the surfaces of the valve block are galvanized. The auxiliary oil way valve block has a compact structure, good reliability and small occupied space, and is simply and conveniently assembled with a frame, the degree of complexity of a fully hydraulic truck-mounted forklift hydraulic pipeline can be effectively reduced, and the assembly and maintenance performances of the truck-mounted forklift hydraulic pipeline are improved.

Description

Static pressure is assisted oil circuit valve piece with the car fork truck with front truck

Technical field

The utility model relates to a kind of valve piece, mainly is that a kind of static pressure is assisted oil circuit valve piece with the car fork truck with front truck.

Background technique

With the car fork truck is a kind of fully hydraulic driven, the high-performance field work fork truck of static pressure walking, because its function with car, the fork lift truck structure space is narrower and small, and the oil circuit more complicated, the rail assembling brings very big difficulty, in order to reduce the I﹠ M difficulty of oil pipe, needs a kind of auxiliary oil circuit valve piece of front truck of all-hydraulic fork truck special use.

The model utility content

Technical problem to be solved in the utility model provides a kind of static pressure and assists oil circuit valve piece with the car fork truck with front truck, and it reduces the complexity that whole hydraulic system pipeline connects, and improves the convenience that system pipeline is safeguarded.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of static pressure with the auxiliary oil circuit valve piece of front truck, includes the valve piece with the car fork truck, has a plurality of test hydraulic fluid ports on the leading flank of described valve piece; Upper and lower off-front wheel A1 hydraulic fluid port, the relief valve C hydraulic fluid port of having successively of described left surface; The position of the corresponding relief valve C of described right flank hydraulic fluid port has the near front wheel A1 hydraulic fluid port, and two hydraulic fluid ports were connected by connecting tube; Described going up on the plane has flow divider valve B hydraulic fluid port, flow divider valve A hydraulic fluid port successively; One test hydraulic fluid port of described leading flank reaches the flow divider valve B hydraulic fluid port of going up the plane with the off-front wheel A1 hydraulic fluid port of left surface and is connected; Another test hydraulic fluid port of described leading flank is connected with the flow divider valve A hydraulic fluid port on last plane; The described flow divider valve A hydraulic fluid port of going up the plane is connected with the and arranged on left and right sides face being connected connecting tube of hydraulic fluid port.

Described valve piece adopts the 45# forging to make by valve piece blank and forms, mill, bore, clamp machining after the forging more successively, and zinc-plated processing is carried out on last surface.

Have a plurality of bolts hole on the described valve piece, the packaged timing of valve adopts bent plate to connect with vehicle frame by bolt, and corresponding hydraulic fitting and hydralic hose are installed on described each hydraulic fluid port of valve piece.

The valve piece adopts the 45# forging to make and forms good pressure-resistant performance in the utility model; Appropriate design valve piece internal holes can reduce hydraulic joint quantity, reduces the pipeline complexity; Appropriate design valve piece hydraulic fluid port opening direction can reduce the oil pipe assembling difficulty, improves the oil pipe assembly space; Rationally establish tapped hole, can simple and effectively assemble with vehicle frame, simple aspect is installed, safeguarded to good reliability.

The test hydraulic fluid port of leading flank is two hydraulic fluid ports of reserving for convenient test in the utility model, blocks up with plug when work.

The utility model has the advantages that:

The utility model compact structure, good reliability, simple and convenient with the assembling of vehicle frame, it is little to take up room, and can effectively reduce all-hydraulic complexity with car fork truck pipeline, has improved the I﹠ M performance with car fork truck hydraulic pipe line.
