Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model comprises driving mechanism, hold-fast body, push-and-pull hydraulic cylinder and base, and described push-and-pull hydraulic cylinder 2 is fixed on base 3; The action of described push-and-pull hydraulic cylinder 2, after driving mechanism transmission, then is held pipeline tightly by hold-fast body and is driven pipeline to move, and described hold-fast body comprises again link press span 13, holding tube frame 9 and axis tile 10; Described link press span 13 is affixed with axis tile 10, hinged with the crank 6 of driving mechanism by axis tile bearing pin 16; Described driving mechanism comprises front connection 4, drive link 1, kinematic link 5 and crank 6; Described front connection 4 links together each kinematic link 5; Meanwhile, described front connection 4 is also in transmission connection by drive link 1 and push-and-pull hydraulic cylinder 2; Described kinematic link 5 is hinged by pitman pin 17 with crank 6, and the bottom of described crank 6 is hinged by axis tile bearing pin 16 and link press span 13.The thrust of described push-and-pull hydraulic cylinder 2 acts in front connection 4 through drive link 1, makes front connection 4 drive crank 6 around crank pin 7 rotations by kinematic link 5, and described crank 6 rotarily drives hold-fast body and produces the radial motion towards tube wall; When axis tile 10 touches after tube wall, the piston rod of push-and-pull hydraulic cylinder 2 moves forward, the positive pressure that makes axis tile 10 produce tube wall after driving mechanism, under the effect of frictional force, when the piston rod of push-and-pull hydraulic cylinder 2 moves forward again, the direction motion that just drives pipeline 12 to stretch out to piston rod.Because the thrust of push-and-pull hydraulic cylinder 2 is directly proportional to the enclasping force of axis tile 10, thrust is larger, and the frictional force that acts on tube wall is larger, so can not produce the phenomenon of skidding on tube wall.
When push-and-pull hydraulic cylinder 2 advances after a stroke, the piston rod of push-and-pull hydraulic cylinder 2 is retracted backward, connection 4 before drive link 1 drives, kinematic link 5, crank 6 and axis tile 10 are to the direction motion with contrary before, thereby axis tile 10 and tube wall are departed from, until push-and-pull hydraulic cylinder 2 and hold-fast body are retracted into initial position, prepare next work cycle.In addition, as shown in Figure 2 and Figure 3, axis tile 10 is set to three groups, every group of four peripheries that are distributed on pipeline 12; The quantity of described crank 6 and the position of tri-joint mechanism can be determined according to the requirement of the required clamping force of pipeline of different tube diameters, described crank 6 is more than or equal to four, and the lenth ratio between the length in described crank 6 between pitman pin 17 hinges and crank pin 7 hinges and axis tile bearing pin 16 hinges and crank pin 7 hinges is that 2:1 is between 10:1.
The utility model has been set up pipeline roller 14 and pipe-supporting roller group 8; Described pipe-supporting roller group 8 and pipeline roller 14 are located on base 3 and hold-fast body, and 14 pairs of pipelines of pipeline roller play centralizing function, and 8 pairs of pipe-supporting roller groups are held pipeline tightly and played a supportive role, and can rotate, and reduce the running resistance of pipeline.Drive link 1 is connected bearing pin 15 with push-and-pull hydraulic cylinder 2 use and connects, and makes to have certain modulability between drive link 1 and push-and-pull hydraulic cylinder 2, in conveyance conduit process, can finely tune, and it can be advanced according to designing requirement.In addition, have additional again axis tile pad 11 on axis tile 10, described axis tile pad 11 can protect pipeline anticorrosion coating not to be damaged, to strengthen the frictional force between enclasp device and tube wall.
In a word, the utility model, in the Pipeline Crossing Program of long distance, bad ground, helps to promote whole piece and goes back to hauling pipe road, increases construction length and the adaptive capacity to bad ground that horizontal directional drill method is passed through, has strengthened the application area that horizontal directional drill method is passed through.
