A kind of device for the lifting section of jurisdiction, this installs on the walking mechanism of chain connection at shield excavation machine, comprises shackle bracket, connection bracket and caliper, wherein,
Shackle bracket and chain connection offer support gathering sill and caliper gathering sill at shackle bracket;
Connection bracket is provided with slide block and power transmission groove, and described slide block slides in the support gathering sill that shackle bracket is offered;
Caliper is symmetrical claw structure, and the upper end of caliper is provided with load bearing pin and guide roller, and described load bearing pin slides in the caliper gathering sill that shackle bracket is offered, and described guide roller slides in the power transmission groove that connection bracket is offered.
Described support gathering sill is opened in the middle part of shackle bracket, cooperates the raised position of control connection support with the slide block on the connection bracket.
Described caliper gathering sill has two, is symmetricly set on the front of shackle bracket, cooperates the open and close of controlling caliper with load bearing pin on the caliper.
The first half of two caliper gathering sills is parallel to each other, and the latter half is close gradually, and the load bearing pin on the caliper is in the open and close of the slip of caliper gathering sill and then control caliper.
Promote shackle bracket, the caliper gathering sill control load bearing pin direction of motion, this moment, slide block moved along the support gathering sill, and when slide block movement during to the support gathering sill bottom of shackle bracket, caliper closure under the effect of load bearing pin is finished and is loaded the section of jurisdiction.
After the assembly unit position of duct piece assembling machine is transported in the section of jurisdiction, under the effect of shackle bracket self gravitation, the load bearing pin moves upward along the caliper gathering sill, when the position that parallels of slide block movement to two caliper gathering sill, gathering sill control load bearing pin, make caliper open the unloading section of jurisdiction, this moment, slide block was born connection bracket and caliper weight, the handling section of jurisdiction of circulating and so forth.
Compared with prior art, the utility model is applied in the engineering practice, is conducive to automation handling section of jurisdiction, and its loading and unloading section of jurisdiction does not need extra power resources, has reduced engineering equipment and has taken construction space; Do not need manually-operated section of jurisdiction alignment pin, avoided occuring because of operation section of jurisdiction alignment pin the possibility of industrial injury, satisfy the working environment that people-oriented, stable work in work, with original transverse beam lifting section of jurisdiction mechanism specifically from loading and unloading section of jurisdiction efficient, take construction space and the contrast of constructor's working strength all is greatly improved.
The utility model is by actual in conjunction with the dark lineman's journey of Guangdong intercity cable release fringe tabernaemontanus bulrush, the result shows: the utility model loading and unloading section of jurisdiction efficient is significantly improved, significantly reduce constructor's working strength, and avoided the constructor that the possibility of industrial injury occurs because of the operation alignment pin.
