Abstract
The utility model discloses a hydraulic transmission control system of a forklift crane and belongs to the technical field of operating equipment manufacturing. The hydraulic transmission control system is composed of an oil tank, a pump body, an oil inlet pipe, an oil return pipe, a forklift reversing valve and a forklift oil cylinder. A four-way manually-operated rotary valve is installed on the oil inlet pipe, the four-way manually-operated rotary valve is provided with an outlet A, an outlet B, an outlet P and an outlet T, the pump body end of the oil inlet pipe is connected with the outlet P, the forklift reversing valve end of the oil inlet pipe is connected with the outlet B, the oil return pipe is connected with the outlet T, the outlet A of the four-way manually-operated rotary valve is connected with a crane reversing valve through an auxiliary oil inlet pipe, the crane reversing valve is connected with a crane oil cylinder, and the oil return pipe is also connected with an oil return port of the crane reversing valve. When the hydraulic transmission control system of the forklift crane works, the four-way manually-operated rotary valve is moved to enable hydraulic oil to respectively drive the forklift oil cylinder and the crane oil cylinder to move. The hydraulic transmission control system of the forklift crane meets the requirement of complete machine hydraulic transmission of a forklift and a crane, is safe and reliable in using performance and convenient to operate, and does not degrade original system technical performance.
Description
Technical field
The utility model belongs to implement manufacturing technology field, is specifically related to a kind of hydraulic transmission control system.
Background technique
Balance weight type diesel fork lift trucks (hereinafter to be referred as fork truck), good stability, be suitable for heavy duty, but can't move height or goods far away.Truck-mounted crane can be by shear leg the lifting of variation, the revolution in plane and hoisting mechanism of flexible, change angle, goods is placed on appointed area, complete the operating mode that fork truck can't be realized.The occupied ground area is large but use simultaneously two equipment of fork truck and crane at the cargo handling scene, and two equipment need independent personnel operation.The loop wheel machine of truck-mounted crane is arranged on fork truck, is combined into forklift truck lifting equipment, can make equipment have fork truck and two kinds of functions of loop wheel machine.because fork truck has a complete Hydraulic Power Transmission System of cover, its Hydraulic Power Transmission System is by fuel tank, the pump housing, oil inlet pipe, return tube, fork truck selector valve and fork truck oil cylinder form, by the pump housing, the hydraulic oil in fuel tank is supplied to the fork truck oil cylinder through oil inlet pipe during operation, controlled by the fork truck selector valve, then hydraulic oil returns to fuel tank through return tube, loop wheel machine equally also needs this system, if use the fork truck original system, can effectively reduce volume and the cost of equipment, but guarantee that this system meets the technical requirements of loop wheel machine, meet simultaneously complete machine in use, the safety requirement that both definitely can not use simultaneously, need to carry out appropriate design to original system, and can not reduce original system technical performance energy.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of hydraulic transmission control system of forklift truck lifting equipment.
the scheme of the utility model technical solution problem is to adopt fuel tank, the pump housing, oil inlet pipe, return tube, fork truck selector valve and fork truck oil cylinder form the hydraulic transmission control system of forklift truck lifting equipment, the four-way hand rotary valve is installed on oil inlet pipe, the four-way hand rotary valve has A, B, four outlets of P and T, the pump housing end of oil inlet pipe connects the P outlet, the fork truck selector valve end of oil inlet pipe connects the B outlet, return tube connects the T outlet, the A outlet of four-way hand rotary valve connects the crane selector valve by auxiliary oil inlet pipe, the crane selector valve connects the crane oil cylinder, return tube also connects the oil return port of crane selector valve.During operation, when needs fork truck cylinder action, moving the four-way hand rotary valve makes B, P export connection, when needs crane cylinder action, move the four-way hand rotary valve and make A, P export connection,, if temporarily both do not wanted the fork truck cylinder action, do not want again the crane cylinder action, move the four-way hand rotary valve and make T, P export connection, hydraulic oil circulates between fuel tank and four-way hand rotary valve.
The utility model is met the complete machine hydraulic transmission of fork truck and crane by a cover system, usability is safe and reliable, and is easy to operate, and does not reduce the original system technical performance.
Description of drawings
Accompanying drawing 1 is system connection diagram of the present utility model.
Embodiment
The utility model consists of fuel tank 1, the pump housing 2, oil inlet pipe 3, return tube 4, fork truck selector valve 5 and fork truck oil cylinder 6, four-way hand rotary valve 7 is installed on oil inlet pipe 3, four-way hand rotary valve 7 has A, B, P and four outlets of T, the pump housing 2 ends of oil inlet pipe 3 connect the P outlet, fork truck selector valve 5 ends of oil inlet pipe 3 connect the B outlet, return tube 4 connects the T outlet, the A outlet of four-way hand rotary valve 7 connects crane selector valve 9 by auxiliary oil inlet pipe 8, crane selector valve 9 connects crane oil cylinder 10, and return tube 4 also connects the oil return port of crane selector valve 9.
