Description of drawings
Below in conjunction with description of drawings the utility model specific embodiment, wherein:
Fig. 1 is the front view that the utility model adopts tire type gantry container crane first embodiment of mains-supplied;
Fig. 2 be the utility model embodiment of tire type gantry container crane of adopting mains-supplied along A to view;
Fig. 3 is the pier storage yard runway scheme drawing that the utility model adopts the tire type gantry container crane walking of mains-supplied.
The specific embodiment
See also Fig. 1 and Fig. 2, the RTG 100 of employing mains-supplied of the present utility model comprises a portal frame 10, complete machine current supply circuit and a plurality of electrical motor, comprises cart drive motor 141, trolley drive motor 142, lifting motor 143.The characteristics of this RTG are that the complete machine current supply circuit can be connected with utility grid by cable 18, adopt mains-supplied as power resources.Because cable 18 need cooperate the distance of RTG and electrical network to carry out folding and unfolding when RTG walks, therefore need to adopt the mechanism of a twisted and released of the cable, below describe, but it is not to be used to limit the utility model for an embodiment.
Fig. 1 illustrates the front view that the utility model adopts an embodiment of tire type gantry container crane of mains-supplied.As shown in the figure, RTG 100 comprises a cable reel 16 and leads cable frame 19.Cable reel 16 is located on the portal frame 10 1 side leg place platforms 17, is used for folding and unfolding cable 18, and the height of platform 17 can change as required.Leading cable frame 19 is located on the vehicle frame steel structure of portal frame 10 1 side bottoms.Cable 18 is wrapped on the cable reel 16, and the one end is connected with the complete machine current supply circuit of RTG 100, is used for by the complete machine current supply circuit a plurality of electrical motors being powered, and its other end is provided with quick plug, is used for being connected with the joint box 20 of civil power.
See also Fig. 3, the corresponding runway that is provided with under cable reel 16, it is example that Fig. 3 only lifts two runways, be on the runway 1,2, be provided with the cable duct 22 of one corresponding runway, this cable duct 22 bearing of trends and runway heading, i.e. the direction of travel unanimity of RTG 100 (the C direction of arrow among Fig. 3).In the terminal of cable duct 22, be provided with city's connection box 20, city's connection box 20 is connected with utility grid, is used for power supply, and city's connection box 20 is provided with the socket that cooperates with cable plug.The other end of cable 18 is drawn from cable reel 16 and is hung down, and the cable frame 19 of leading of process floor level falls into ground cable duct 22, and is connected with city's connection box 20 of being located at cable duct 22 terminals along cable duct 22.Cable 18 all drops in the cable duct 22 in ground-surface part.
The direction (the B direction of arrow among Fig. 2) that the face at cable reel 16 places and RTG 100 advance is parallel so that folding and unfolding cable 18 freely.The height of leading cable frame 19 is used for pilot cable 18 and makes it straight near ground, enters in the ground-surface cable duct 22, and can be pressed onto by the tire of RTG 100 and other vehicular traffics.Guarantee the safety of cable 18.Yet it is not necessary leading cable frame 19, if when the setting height(from bottom) of cable reel is low, cable guarantees that from Beijing South Maxpower Technology Co. Ltd it accurately falls in the trailing cable groove.
Though cable reel 16 of the present utility model, cable 18 shown in Fig. 1 and lead cable frame 19 and place portal frame 10 inboards are arranged needs according to harbour, cable reel 16, cable 18 and lead cable frame 19 and also can place portal frame 10 outsides.
Fig. 3 is a pier storage yard runway scheme drawing.Be provided with the runway of two RTG 100 among Fig. 3, be respectively runway 1 and runway 2, when RTG 100 worked on runway 1, the quick plug of cable 18 was inserted on the socket of city's connection box 20 of the runway end, and its ground segment drops in the cable duct 22.When RTG 100 when stockyard runway 1 runs to the operation of each case position, realize the folding and unfolding of cable 18 according to the RTG 100 and the distance of city's connection box 20 by cable reel 16, guarantee continuous electric power supply, guarantee that by leading cable frame 19 the straight of power cable 18 enters in the trailing cable groove 22 to guarantee cable security simultaneously.
When RTG 100 needs the cart transition to another runway 2, the cable 18 of RTG 100 is extracted the city's connection box that is inserted on the runway 2 from city's connection box of runway 1, the city's connection box power supply on the duty runway 2 is carried out operation at runway 2.
By above scheme, the power supply mode of RTG 100 can be changed into by utility grid and powering, the RTG of this use civil power is conventional uses the RTG of diesel powerplant as propulsion source, simple in structure, safe and reliable, maintaining is easy, efficiently, economy, pollution-free, can be referred to as the RTG of environmental type.
