Fig. 2 is a structure left view of the present invention.
Fig. 3 is a structure birds-eye view of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
The present invention has one unit of one's own, is installed between the equipment of former simple lay car and folding and unfolding, and forms an extension and retraction system jointly with former simple lay car.It adopts two driver slot wheel constructions, as shown in Figure 1, its structure is made up of pedestal 1, fairlead 2, cant cantilever 3, main frame 4, hog frame 5, armouring umbilical cable 6 or steel rope, driving sheave 7, oil motor damper brake assembly 8, planetary reducer 9, backup bearing 10, wherein:
Described pedestal 1, cant cantilever 3, main frame 4, hog frame 5 adopt welding process that they are fitted together, and constitute general frame, and these members all adopt box type construction; Pedestal 1 is the basic framework of this device, and other is purchased part and all welds and be installed on this basic framework; Main frame 4 is vertically welded on the pedestal 1 and cant cantilever 3 provides support for two axles systems based on driving sheave 7 together; Owing to require this two necessary cantilevers of axle system, if the independent cantilever of difference, the one, precision is difficult to guarantee, the 2nd, can't bear bigger load, so adopted the very big cant cantilever 3 of rigidity to be welded on the version of main frame 4 right side (see figure 2)s, cant cantilever 3 guarantees promptly that for above-mentioned two axles are to provide support cantilever has enough rigidity again; For guaranteeing the rigidity of general frame, hog frame 5 is welded on the left side (see figure 2) of main frame 4, simultaneously with pedestal 1 weld together;
Described fairlead 2 is screwed on pedestal 1, so that the adjustment of position, it leads the cable groove up, and leading the cable groove and should aliging with the circular groove that drives sheave of fairlead drives sheave at every in case of necessity and 7 times fairlead 2 be housed all;
Described oil motor damper brake assembly 8 be installed in planetary reducer quiet flange on, in fact oil motor and damper brake assembly 8 are two parts independent of each other, but often maker apolegamy assembles, so also can regard an assembly as; The shell of oil motor damper brake assembly 8 and the quiet flange of planetary reducer 9 are screwed together, planetary reducer 9 also is installed on the main frame with screw by its quiet flange simultaneously, and the moving shell of planetary reducer 9 cooperates fixed connection with the endoporus that drives sheave one side;
Described driving sheave 7 by its opposite side the axle be installed in cant cantilever 3 on backup bearing 10 cooperate, a side that drives sheave 7 is supported by main frame 4 by planetary reducer 9, opposite side is supported by cant cantilever 3 by bearing 10, because cant cantilever 3 also is welded on the main frame 4, so, for two driving sheaves 7, be cantilevered fashion from integral structure;
Described armouring umbilical cable 6 is to be used for traction by retractable equipment, an end be connected by retractable equipment, the other end is connected with low-tension winch (former simple lay car), centre portion is wrapped in two circular grooves on the driving sheave 7 by helix line rule leap;
Described driving sheave 7, oil motor damper brake assembly 8, planetary reducer 9 and bearing 10 are two covers, symmetrical expression is arranged on the pedestal 1, and the model of two cover oil motor damper brake assembly 8 and planetary reducers 9 is identical with parameter index, and wherein damper brake is a normally closed.
Principle of work of the present invention is:
Radical function of the present invention is that tension force amplifies, also we can say can be with the bigger tension force that bears by the present invention, when the extension and retraction system operation, the low-tension winch is all the time with lower tension force folding and unfolding armouring umbilical cable 6, by producing bigger tension force behind the tension force amplification winch.So, how does tension force amplify? ask for an interview Fig. 1, armouring umbilical cable 6 is striden and is entangled in two and drives on the sheaves 7 along driving circular groove one circle circle on the sheaves 7, is similar to the transmission of joint group V-belt, and just each is self-enclosed for the V-strapped every V-belt of joint group.In the process of folding and unfolding cable, the low-tension winch is bestowed armouring umbilical cable 6 basic unmodified tension force, and bestowed the bigger tension force of armouring umbilical cable 6 at the other end by retractable equipment, the circular groove that these tension force make 6 pairs of armouring umbilical cables drive on the sheave 7 produces pressure, according to mechanics principle, produce friction force between the circular groove on armouring umbilical cable 6 and the driving sheave 7, when driving sheaves 7 rotation synchronously for two, because the effect of friction force drives sheave 7 and drives 6 motions of armouring umbilical cable.According to the strap drive principle, the tension force of the big more generation of the cornerite of band is big more, so change the magnification factor that the size (change the groove that drives sheave 7 in other words and count N) of cornerite can change tension force.Put into practice verifiedly, the groove number that the low-tension winch is bestowed the size of armouring umbilical cable 6 tension force and driven sheave 7 determines the big tractive force limit of whole extension and retraction system.
