Abstract
A tandem oil cylinder comprises a first hydraulic cylinder, a second hydraulic cylinder and side tracks arranged on two sides, wherein a fixing seat is arranged at one end of each side track; a lug is arranged on the fixing seat hinged with a cylinder body of the first hydraulic cylinder; a traveling car is hinged on a piston rod of the first hydraulic cylinder; rollers matched with the side tracks are arranged on the traveling car; and the tail end of a cylinder body of the second hydraulic cylinder is hinged with the other end of the traveling car. The manner of combining oil cylinder groups is adopted, and the first hydraulic cylinder and the second hydraulic cylinder are connected in series through small walking wheels, thus the supporting stability is reliably ensured while the stroke is increased, the cost is lower, the effect is good, the turning is achieved at the tandem connection part, the tandem oil cylinder is suitable for pushing and raising objects with a larger angle of rotation round a shaft, and the use range is wide, the structure is simple, the convenience is brought for the manufacturing and the installation, and the safety performance is high.
Description
(1) technical field
The utility model relates to a kind of mechanical device, specifically is a kind of serial connection oil cylinder.
(2) background technique
Existing oil cylinder all is a single structure, and stroke is short, the big shortcoming that has unstability of slenderness ratio, and using effect is poor.
(3) summary of the invention
The technical problem that the utility model will solve provides a kind of serial connection oil cylinder, and can increase stroke distances and realize turning back at the serial connection place, the suitable election bigger object of angle that sways, using scope is wide, good stability, effect is good.
For this reason, the utility model is taked following technological scheme:
A kind of serial connection oil cylinder; Include first oil hydraulic cylinder, second oil hydraulic cylinder and be arranged in the side rails of both sides, said side rails one end is provided with fixed base, and said fixed base is provided with lug; Hinged with the cylinder body of first oil hydraulic cylinder; Be hinged with a travelling car on the piston rod of said first oil hydraulic cylinder, said travelling car is provided with the roller that cooperates with side rails, and the cylinder body tail end of said second oil hydraulic cylinder and the other end of travelling car are hinged.
Roller on the said travelling car is four, all around symmetric arrangement.
Said side rails is provided with limiting stopper away from the other end of fixed base, and said limiting stopper offsets with roller and cooperates.
The side rails of said both sides connects through connecting shelves, and said connection shelves are arranged in the upper and lower end face of side rails.
Employing the utlity model has following advantage: 1, adopt the compound mode of oil cylinder group, first oil hydraulic cylinder and second oil hydraulic cylinder are realized serial connection through the steamboat of walking, and reliable assurance is supported when increasing stroke stability and cost are lower, effective; 2, the serial connection place realizes turning back, the suitable election bigger object of angle that sways, and using scope is wide; 3, simple in structure, manufacturing and easy for installation, Safety performance is high.
(4) description of drawings
Fig. 1 is the utility model travelling car structural representation;
Fig. 2 is the utility model side rails structural representation.
(5) embodiment
With reference to Fig. 1-2, a kind of serial connection oil cylinder includes first oil hydraulic cylinder 1, second oil hydraulic cylinder 2 and is arranged in the side rails 3 of both sides; Said side rails one end is provided with fixed base 4; Said fixed base is provided with lug 5, and is hinged with the cylinder body of first oil hydraulic cylinder, is hinged with a travelling car 6 on the piston rod of said first oil hydraulic cylinder; Said travelling car is provided with the roller 7 that cooperates with side rails, and the cylinder body tail end of said second oil hydraulic cylinder and the other end of travelling car are hinged.Roller on the said travelling car is four, all around symmetric arrangement.Said side rails is provided with limiting stopper 8 away from the other end of fixed base, and said limiting stopper offsets with roller and cooperates.The side rails of said both sides connects through connecting shelves 9, and said connection shelves are arranged in the upper and lower end face of side rails.When first oil cylinder was worked, second oil cylinder was just along with travelling car is pushed, treat that travelling car and limiting stopper offset after, second oil cylinder is started working.Elder generation's retraction second oil cylinder when resetting, first oil cylinder again bounces back.
Claims (4)
