Abstract
The utility model relates to a lifting hydraulic pressure speed adjusting device for a fork truck. Nowadays, the lifting speed of the electric fork truck can not be adjusted and is provided with no buffer. The utility model comprises a lifting oil cylinder; an oil inlet and an outlet are arranged at the lower part of the lifting oil cylinder, and the lifting oil cylinder is communicated with a pipeline and an oil pump through the oil inlet and outlet opening; the motor is matched and connected with the oil pump, a motor controlling device is connected with the motor. The rotating speed of the motor can be controlled through the motor controlling device by the utility model so that the oil inputting speed of the oil pump is controlled, further, the fork arm speed can be controlled so that the stopping dead of the fork is avoided and the service life of the forklift truck is prolonged.
Description
Technical field
The utility model relates to a kind of electri forklift, specifically is the hydraulic speed regulating device that hoists of fork truck.
Background technology
Electri forklift is a kind of handling machinery, and it has walking and promotes the function of goods.Fork truck is in actual job, and pallet fork inserts the bottom of goods, and pallet fork moves up along door frame then, deliver to the position after, again pallet fork is moved down, extract pallet fork out from the goods bottom.The lifting of electri forklift pallet fork at present is to drive by oil cylinder, and oil cylinder is by electric machine control, can not carry out the speed adjustment.In operating process, when promoting or dropping to a certain height, because can not automatically regulating speed, the speed of pallet fork upstream or downstream can stop suddenly, and buffering not influences service life of fork truck on the one hand, may damage Loaded goods on the other hand.
Summary of the invention
The purpose of this utility model just provides a kind of hydraulic speed regulating device that hoists of fork truck.
The utility model comprises lift oil tank, and the lift oil tank bottom is provided with oil inlet and outlet, and lift oil tank is communicated with oil pump by oil inlet and outlet and pipeline, and motor and oil pump are connected, and motor control assembly is connected with motor.
Motor control assembly in the utility model adopts existing mature technology, can realize the control to motor speed, and inventive point of the present utility model is motor control assembly is applied in the erecting equipment of fork truck.
The utility model can be controlled rotating speed of motor by motor control assembly, thereby controls the speed oil that of oil pump, and then can control the speed of pallet fork, has avoided pallet fork to stop suddenly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the fork truck hydraulic speed regulating device that hoists comprises lift oil tank 1, and lift oil tank 1 bottom is provided with oil inlet and outlet 2, and lift oil tank 1 is communicated with oil pump 4 by oil inlet and outlet 2 and pipeline 3, motor 5 is connected with oil pump 4, and motor control assembly 6 is connected with motor 5.
In the work, by the size of control motor control assembly outgoing current, control the speed of motor speed, thereby control the speed oil that of oil pump, and then can control the speed of pallet fork.At the stroke medium velocity hurry up, near stop position the time speed more slowly, thereby avoided pallet fork to stop suddenly.
Claims (1)
1, the fork truck hydraulic speed regulating device that hoists comprises lift oil tank, it is characterized in that the lift oil tank bottom is provided with oil inlet and outlet, and lift oil tank is communicated with oil pump by oil inlet and outlet and pipeline, and motor and oil pump are connected, and motor control assembly is connected with motor.
