Abstract
The invention discloses an electric hydraulic lifting car with an automatic control system. The electric hydraulic lifting car with the automatic control system comprises an electric hydraulic lifting car body, wherein the electric hydraulic lifting car body mainly consists of a car frame (1), a motor, a fork (2), a gear pump, a check valve, a working cylinder (3), an overflow valve (4) and an oil tank. The electric hydraulic lifting car with the automatic control system is also provided with an automatic control system, wherein the automatic control system consists of a photoelectric switch probe (5) and a bracket (6); the bracket (6) is installed on the car frame (1); the photoelectric switch probe (5) is installed on the bracket (6); and the signal output end of the photoelectric switch probe (5) is electrically connected with the power supply of the motor. The electric hydraulic lifting car with the automatic control system, which is disclosed by the invention, has the advantages that machine, electricity and light integration is introduced into the hydraulic forklift field, and the automatic control system is additionally arranged on the basis that lifting or lowering is manually controlled, thereby being safer and more convenient to operate, saving more power and better protecting the environment.
Description
Technical field
The present invention relates to electric hydaulic rising car field, be specifically related to a kind of rising of the electric hydaulic with autonomous cruise speed system car.
Background technology
?at present, existing electric hydaulic rising car power unit is divided into interchange, the large series of direct current two.Its principle of work is by master cock push button start manually or stops power unit, by oily suction pumping cylinder in Hydraulic Station, then squeezes in clutch release slave cylinder, makes goods lifting or decline.Although existing electric hydaulic rising car lifting is steady, economical and practical, needs manual operation, has taken human resources, has increased shipping and delivery cost.And, when lot cargo loads and unloads, the workman does identical action, easily misoperation repeatedly, causes adverse consequences.
Summary of the invention
Purpose of the present invention is exactly at present, and existing electric hydaulic rising car power unit is divided into interchange, the large series of direct current two.Its principle of work is by master cock push button start manually or stops power unit, by oily suction pumping cylinder in Hydraulic Station, then squeezes in clutch release slave cylinder, makes goods lifting or decline.Although existing electric hydaulic rising car lifting is steady, economical and practical, needs manual operation, has taken human resources, has increased shipping and delivery cost.And, when lot cargo loads and unloads, the workman does identical action, easily misoperation repeatedly, causes the deficiency of adverse consequences, and a kind of rising of the electric hydaulic with autonomous cruise speed system car is provided.
The present invention includes electric hydaulic rising car body, electric hydaulic rising car body mainly is comprised of vehicle frame, motor, pallet fork, gear type pump, check valve, operating cylinder, by pass valve and fuel tank, it also has autonomous cruise speed system, autonomous cruise speed system is comprised of photo-switch detector and support, support is arranged on vehicle frame, and be positioned at a side of vehicle frame, and photo-switch detector is rack-mount, and the signal output part of photo-switch detector is electrically connected to the power supply of motor.
It also has explosion-proof solenoid valve, and the oil outlet of operating cylinder communicates with the oil inlet of by pass valve by explosion-proof solenoid valve, and the signal output part of explosion-proof solenoid valve is electrically connected to motor power.
Advantage of the present invention is: the present invention, by photoelectrome chanical integration introducing hydraulic forklift field, has increased autonomous cruise speed system, safer, more laborsaving, more convenient operation, more environmental protection on the basis of original manual control lifting or decline.Increased system protection device.Added explosion relief valve in hydraulic efficiency pressure system, when unexpected explosion or oil circuit appear in oil pipe, unexpected dangerous situation occurred, system protection device can be automatically by the goods slow decreasing be raised, thereby personal safety and equipment are played a protective role.
the accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is hydraulic principle structural representation of the present invention.
The specific embodiment
As shown in Figure 1, 2, the present invention includes electric hydaulic rising car body, electric hydaulic rising car body mainly is comprised of vehicle frame 1, motor, pallet fork 2, gear type pump, check valve, operating cylinder 3, by pass valve 4 and fuel tank, it also has autonomous cruise speed system, autonomous cruise speed system is comprised of photo-switch detector 5 and support 6, and support 6 is arranged on vehicle frame 1, and is positioned at a side of vehicle frame 1, photo-switch detector 5 is arranged on support 6, and the signal output part of photo-switch detector 5 is electrically connected to the power supply of motor.
It also has explosion-proof solenoid valve 7, and the oil outlet of operating cylinder 3 communicates with the oil inlet of by pass valve 4 by explosion-proof solenoid valve 7, and the signal output part of explosion-proof solenoid valve 7 is electrically connected to motor power.
Mode of operation: press shift knob, pallet fork 4 can automatic-ascending, and when photo-switch detector 5 detects on pallet fork 4 goods, pallet fork 4 stops rising, and other items take away after, pallet fork 4 is automatic-ascending again.When pallet fork 4 rises to end position, pallet fork 4 stops rising, and waits for the decline instruction.Press the decline shift knob, pallet fork 4 descends.When pallet fork 4 drops to extreme lower position, pallet fork 4 stops descending automatically.
This elevator can be carried out Manual lifting, decline function by the handle line traffic control, and can automatically stop in the high-low limit position.
The explosion relief valve mode of operation: unexpected dangerous situation occurs when unexpected explosion or oil circuit appear in oil pipe, system protection device can be automatically by the goods slow decreasing be raised, thereby personal safety and equipment are played a protective role.
