The forklift steering device is a steering device which is matched with the existing forklift steering device and can realize the steering of the front wheel; therefore, two steering devices can be operated at the same time so as to realize the steering of the front wheel and the rear wheel of the forklift within 0-90 DEG; therefore, the forklift can run in any directions such as front, rear, left, right and any directions among the front, rear, left and right direction, thus realizing the all-directional running of the forklift.
Description
Technical field
The present invention relates to a kind of steering hardware, especially a kind of steering hardware cooperating of and existing fork truck is to realize the fork truck steering device of fork truck omnidirectional running.
Background technology
The tradition fork truck has only a cover steering hardware, promptly turn to oil cylinder or steering motor to realize fork-truck steering by bearing circle, deflector control, promptly realize the needs that turn to of rear drive sprocket by existing steering hardware, yet this fork truck with a cover steering hardware, be merely able at the direction running that limits, can not omnidirectional running (omnidirectional running promptly can travel towards any direction).
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is that a cover steering hardware that overcomes prior art can not be realized the defective of fork truck omnidirectional running, provides a kind of and can be used fork truck steering device with the omnidirectional running of realizing fork truck with existing steering hardware.For this reason, the present invention is by the following technical solutions:
Fork truck steering device, it is characterized in that on preceding stretching one's legs, installing and turn to oil cylinder, be used to drive front-wheel cw or anticlockwise motion by moving behind the piston rod that turns to oil cylinder or moving forward and drive the front-wheel gyro-rotor by connecting rod, the described oil cylinder that turns to is connected to convertible valve by oil pipe, attended operation handle on the convertible valve;
Be connected with the connecting rod swing arm on the described piston rod that turns to oil cylinder, an end of described connecting rod is connected the position of departing from described piston rod on the connecting rod swing arm, and its other end is connected on the front-wheel gyro-rotor;
Described connecting rod comprises one section straight bar section, and bending segment is extended at the two ends of this straight bar section respectively, this two bending segment respectively with described connecting rod swing arm on depart from described piston rod the position be connected with the front-wheel gyro-rotor.
As the further of technique scheme improved and replenishes, make such scheme have more operability and rational in infrastructure flexible, the present invention also comprises following additional technical feature:
Described fork truck steering device is characterized in that described convertible valve is superimposed upon on the multiway valve of fork truck.
The steering hardware of the present invention by providing a kind of and existing fork truck steering device to match and use, this device can be realized turning to front-wheel, thus, operating two steering hardwares simultaneously can realize the fork truck front and back wheel is carried out 0 °～90 ° turning to simultaneously, therefore can realize fork truck in front, rear, left and right and any direction in the middle of it travel, promptly realize the omnidirectional running of fork truck.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a fork truck scheme drawing of having used structure of the present invention.
Among the figure: 1-front-wheel, state when 90 ° on 1A-front-wheel turns to, state when 0 ° on 1B-front-wheel turns to, 2-front-wheel gyro-rotor, 3-bearing pin, 4-oil nozzle, 6-connecting rod, 6a/6c-connecting rod bending segment, 6b-connecting rod straight bar section, 8-connecting rod swing arm, connecting rod swing arm position when 90 ° on 8A-front-wheel turns to, connecting rod swing arm position when 0 ° on 8B-front-wheel turns to, 9-steering oil cylinder piston rod, 10-turn to oil cylinder, 11-operating handle, 12-convertible valve, 13-multiway valve, 14-steering oil pipe, 15-preceding stretching one's legs, 16-preceding support wheel, 17-trailing wheel, 18-back support wheel.
The specific embodiment
The present invention will be further described below in conjunction with Figure of description.
As shown in the figure, this fork truck steering device mainly comprises and turns to oil cylinder 10, connecting rod swing arm 8, connecting rod 6, steering oil pipe 14 and convertible valve 12:
It is (general on 15 to stretch one's legs before turning to oil cylinder 10 to be installed in, be to hide in preceding stretching one's legs), turn to the piston rod 9 of oil cylinder 10 to be connected with connecting rod swing arm 8, connecting rod 6 comprises one section straight bar section 6b, bending segment 6a/6c is extended at the two ends of this straight bar section 6b respectively, a bending segment 6a is connected the position of departing from described piston rod 9 axis on the connecting rod swing arm by bearing pin, another bending segment 6c is connected on the front-wheel gyro-rotor 2 by bearing pin 3, and in this junction oil nozzle 4 is installed and keeps it lubricated so that inject lubricating oil, thus, when the piston rod 9 that turns to oil cylinder 10 stretches, promptly can drive front-wheel gyro-rotors 2 and be with front-wheel 1 to turn to by connecting rod 6; To turning to oil cylinder 10 controls to realize by convertible valve 12, this convertible valve 12 is superimposed upon on the multiway valve 13 of fork truck, attended operation handle 11 on it, at convertible valve 12 and turn to and be connected with two steering oil pipes 14 between the oil cylinder 10, therefore, can make flexible turn to (two steering oil pipes replace oil-feed and oil return) of realizing of the piston rod that turns to oil cylinder by the flow direction that convertible valve is controlled hydraulic oil in two steering oil pipes 14 therebetween by operating handle to front-wheel.
As shown in Figure 2, the working forms of existing steering hardware is constant, and a trailing wheel 17 promptly controlling fork truck turns to, as another trailing wheel use cardan wheel of back support wheel 18; When being applied in fork truck steering device shown in Figure 1 on the fork truck, only need to connect on the front-wheel of fork truck this fork truck steering device, use cardan wheel to get final product as another front-wheel of preceding support wheel 16.
During work, chaufeur by control operation handle 7 backward or forward, controlled hydraulic system hydraulic oil is entered through steering oil pipe 14 by convertible valve 9 and turns to oil cylinder, make the piston rod drivening rod swing arm 5 that turns to oil cylinder 6, moving behind the connecting rod 4 or moving forward makes front-wheel gyro-rotor 2 drive front-wheel 1 cws or anticlockwise motion make front-wheel 1 reach 90 ° of position (indicated states of 1A among Fig. 1 of diagram, the connecting rod swing arm 8 of this moment is in the position of 8A among Fig. 1) (the indicated state of 1B among Fig. 1 to 0 ° of position, the connecting rod swing arm 8 of this moment is in the position of 8B among Fig. 1) arbitrarily angled turning to, this turns to and has steering hardware now turning to of trailing wheel cooperated, and can realize the omnidirectional running of fork truck.
