The specific embodiment

Below in conjunction with accompanying drawing scheme of the present utility model is further specified.

As depicted in figs. 1 and 2, the removable jack up crane ship of binary of the present utility model, comprise a double girder gantry crane 5, double girder gantry crane 5 comprises four loop wheel machine supports 51, with four loop wheel machine supports 51 couple together one the circle crossbeam 52, crane ship also comprises left hull 1 and right hull 2, left hull 1 and right hull 2 share an operator's compartment and control cabin that is located at the crane ship head, be goods putting district, deck 3 and lifting zone 4 between left hull 1 and the right hull 2, goods putting district, deck 3 is positioned at regional 4 the place aheads of lifting, wherein two loop wheel machine supports 51 are located on the left hull 1, two other loop wheel machine support 51 is located on the right hull 2, double girder gantry crane 5 can relatively left hull 1 and right hull 2 move forward and backward, can lift goods and move to goods putting district, deck 3 from lifting 4 (waters between left hull 1 and the right hull 2), zone, crossbeam 52 can rise or descend by relative four loop wheel machine supports 51, can arrange two winchs 23 on the crossbeam 52, two winchs 23 are according to actual conditions, can work independently, also can two collaborative works, as shown in Figure 4.

As shown in Figure 6 and Figure 7, be respectively equipped with a jacking system 53 on four angles of each loop wheel machine support 51, jacking system 53 comprises two root posts 531,532, two root posts 531, be provided with between 532 to connect and support 22, two root posts 531, be provided with a plurality of one to one pin-and-holes 91 along its short transverse on 532,92 (Fig. 7 and shown in Figure 10), as shown in Figure 8, it is symmetrical being fixed with on the crossbeam 52 with two root posts 531,532, the a pair of upper cylinder 61 that level is oppositely arranged, 62, correspondingly under a pair of upper cylinder 61,62 be provided with a pair of lower oil cylinder 81,82, lower oil cylinder 81,82 is symmetrical with two root posts 531,532, level is oppositely arranged, a pair of upper cylinder 61,62 and a pair of lower oil cylinder 81, be fixed with a plurality of jacking cylinders 7 between 82, a plurality of jacking cylinders 7 are parallel to two root posts 531,532, so that when a pair of upper cylinder 61,62 piston rod shrinks and leaves respectively its corresponding pin-and-

hole

91,92, its corresponding pin-and-hole 91 is inserted respectively in the piston rod elongation of a pair of lower oil cylinder 81,82,92 when being fixed, the piston rod simultaneous retractable of a plurality of jacking cylinders 7 drives a pair of upper cylinder 61,62, with fixing crossbeam 52 jackings or the decline (shown in Figure 9) of a pair of upper cylinder 61,62; When a pair of upper cylinder 61, its corresponding pin-and-hole 91 is inserted respectively in 62 piston rod elongation, 92 be fixed, a pair of lower oil cylinder 81,82 piston rod shrinks and leaves respectively its corresponding pin-and-

hole

91,92 o'clock, the piston rod simultaneous retractable of a plurality of jacking cylinders 7 drives a pair of lower oil cylinder 81,82 jackings or decline (shown in Figure 11).Because crossbeam is large and heavy, many rising or down maneuvers of above-mentioned upper cylinder, lower oil cylinder being finished jointly crossbeam can be set as required.

The process that rises take crossbeam 52 is as example, be described as follows: when initial, a pair of upper cylinder 61,62 and a pair of lower oil cylinder 81,82 piston rod all inserts corresponding pin-and-

hole

91,92 fixing (shown in Figure 8), then upper cylinder 61,62 piston rod shrinks respectively and leaves corresponding pin-and-

hole

91,92, lower oil cylinder 81,82 piston rod is still and keeps inserting stationary state, this moment, the piston rod of jacking cylinder 7 extended upwards jacking upper cylinder 61,62, thereby drive crossbeam 52 jackings (shown in Figure 9, the piston rod of lower oil cylinder 81,82 keeps inserting stationary state always in this process), after jacking puts in place, the piston rod of upper cylinder 61,62 extends respectively that to insert corresponding pin-and-hole 91,92 (shown in Figure 10, this is oil cylinder 81 at present, 82 piston rod still keeps inserting stationary state), then play the piston rod of oil cylinder 81,82 to shrink respectively and leave corresponding pin-and-

hole

91,92, (shown in Figure 11, upper cylinder 61 in this process for oil cylinder 81,82 upward movements under the piston rod of jacking cylinder 7 shrank and drives, 62 piston rod keeps inserting stationary state always), after the piston rod of jacking cylinder 7 shrank and puts in place, corresponding pin-and-hole 91 was inserted in the piston rod elongation of lower oil cylinder 81,82,92, get back to initial condition shown in Figure 8, finish a displacement, then repeat aforesaid action, finish for the second time, for the third time displacement etc., until crossbeam 52 rises to the high position of hanging that needs, the decline process of crossbeam 52 similarly just repeats no more here.

As shown in Figure 4, in work progress, regulate crossbeam 52 to proper height according to the construction needs; when the navigation of not constructing or stop, crossbeam drops to extreme lower position, and fishhook etc. are placed on goods putting district, deck; center of gravity when reducing ship's navigation, the hanging device of protection loop wheel machine is such as Fig. 3 and shown in Figure 5.
