A base 4 is arranged above the docking mechanism 1, and a hole matched with the tip cone 120 and the second threaded column 119 is formed in the lower surface of the base 4.
The working principle is as follows:
the first step is as follows: under the control of the moving mechanism 3 and the clamping and supporting mechanism 2, the docking mechanism 1 is positioned to a place where an underwater bridge base needs to be installed, the lower half portion of the docking mechanism 1 is inserted into the water bottom, the upper half portion of the docking mechanism 1 is clamped and fixed by the clamping clamps 204, then the base 4 is lifted from the water surface to enter the water bottom, the base 4 is aligned with the docking mechanism 1 and then placed, a hole formed in the bottom of the base 4 is abutted with the tip cone 120 and the threaded column II 119 to complete one-time positioning of installation of the base 4, and therefore errors of the base 4 aligned with the installation place are greatly reduced.
The second step is that: hole and tip cone 120 through base 4 bottom surface, reference column 122 docks, later continue to transfer base 4, base 4 can contact with clamping 204 this moment, because clamping 204's slope sets up, after base 4 contacts clamping 204, because clamping 204's clamp of both sides gets, can be with base 4 gradual push away just, in addition under the extrusion of the lateral wall of base 4, two clamping 204 also can remove to the direction that deviates from gradually, clamping 204 changes from getting riser 106 and getting into getting base 4 and getting this moment, when supplementary base 4 normal position was put, make clamping 204 leave from riser 106, prepare for subsequent removal, positioner's linkage has been improved.
The third step: the base 4 that continues to push down can make the tip cone 120 descend, because the contact of two 119 threaded columns and gear 116, make gear 116 rotate, thereby along the pole setting 115, stand 109 drives gear plate 105 and rotates, thereby make a threaded column 104 rotate in the section of thick bamboo 102, because threaded column 104 and the threaded connection of section of thick bamboo 102, make a threaded column 104 descend along section of thick bamboo 102 rotation, through the meshing between the gear plate 105, make three threaded column 104 all descend in the section of thick bamboo 102 rotation, thereby make a threaded column 104 insert and fix docking mechanism 1 in the submarine that more deepens, make when the base 4 descends fastening docking mechanism 1 and submarine be connected, improve the holistic stability of device.
The fourth step: the stirring ring 111 is connected with the gear 116 through the first spring 117, the stirring ring 111 is connected with the second thread groove 110 through the insertion block 112, when the upright column 109 rotates, the stirring ring 111 firstly rotates under the driving of the first spring 117, and meanwhile, the stirring ring 111 limited by the rotation of the first spring 117 can move back and forth along the upright column 109 up and down, so that the stirring ring 111 drives the cutting piece 113 to poke the first membrane bag 107 and the second membrane bag 108, so that the first membrane bag 107 and the second membrane bag 108 are poked, so that the cement powder and water inside are mixed, and in addition, the stirring is performed under the rotation of the brush 114, so that the cement pouring can be generated in the butt joint mechanism 1, and an auxiliary effect is achieved on the connection stability of the butt joint mechanism 1 and the base 4.
The fifth step: after the hole of base 4 bottom and reference column 122 accomplish the butt joint, the inside cement that generates of docking mechanism 1 can get into the junction of reference column 122 and base 4 through irritating entry 123, and after base 4 and reference column 122 accomplished the butt joint, butt joint portion and submarine water are kept apart, pours into grout into the junction this moment into, and after a period, cement can solidify at the junction to make base 4 and docking mechanism 1 accomplish automatic stable connection through cement.
And a sixth step: start electric telescopic handle 310, make electric telescopic handle 310 shrink, thereby take off clamping 204 from stable base 4's the outside, because the slope setting of clamping 204, and clamping 204 and the swing joint of cross slot 202, make when electric telescopic handle 310 shrinks alright with the easy peeling off of clamping 204 from base 4 down, starter motor 309 rotates in addition, make meshing rotation between gear post 308 and the three 304 of screw thread post, thereby automatic slide movable block 306 along removing post 303, make moving mechanism 3 drive press from both sides right mechanism 2 and move the location installation that carries out base 4 toward next docking mechanism 1 department, make the device pass through moving mechanism 3 and press from both sides right mechanism 2, be convenient for carry out positioning process to subsequent base 4, make the device once only can accomplish many times location, improve the work efficiency of location.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
