The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 8, present embodiment is used for travelling car the translation course of conveying of large-scale steel pipe 9 as Fig. 1.The walking of travelling car is installed in this travelling car on two tracks 1 in the present embodiment for convenience, and two tracks 1 are laid immediately on the ground, and perhaps according to the particular case at scene, track 1 also can be installed on the purpose made platform.
This travelling car comprises:
Vehicle body 2, the vehicle body in the present embodiment is case structure, is provided with following hydraulic actuating cylinder 4 in it;
Top board 3 is arranged on the vehicle body top, can do moving up and down under the effect of following hydraulic actuating cylinder 3;
Hydraulic actuating cylinder 4 is arranged in the vehicle body 2, and the piston rod 12 of this hydraulic actuating cylinder 4 is captiveed joint with top board 3;
Fuel tank 13, for the cause of conveniently moving, the fuel tank 13 in the present embodiment also is arranged in the vehicle body 2; In the actual production, according to the situations such as scale of factory, fuel tank also can be arranged on other place, and it is connected by pipeline with hydraulic actuating cylinder and gets final product;
Oil pump 5 also is arranged in the vehicle body 2, and the oil inlet of oil pump 5 links to each other with fuel tank 13, and its oil outlet connects following electromagnetic direction valve 6;
Solenoid directional control valve 6 adopts three position four-way directional control valve in the present embodiment, the first outlet A of this three position four-way directional control valve exports rodless cavity and the rod chamber that B is connected hydraulic actuating cylinder 4 respectively with second;
Roller 7, carrying is installed in the below of vehicle body 2, rolls on track 1 separately;
Baffle plate 8 has polylith, is arranged on the top of top board 3, is used for steel pipe 9 spacing at top board 3;
