Embodiment
The present invention is not limited by following embodiments, can be determined with technique according to the invention scheme and actual conditions Specific embodiment.Make following describe to the present invention with reference to Fig. 1, Fig. 2.The position relationship of upper and lower, left and right etc. be according to Determined according to the layout direction of Figure of description 1.
Outer barrel 9 is enclosed on the outside of inner cylinder 11, and the outside of outer barrel 9 installation wheel carrier 8, roller 7 is installed in the end of wheel carrier 8.Inner cylinder 11 Centre set among oil cylinder 10, supporting plate 6 is disc, and middle one end of oil cylinder 10 is installed in supporting plate 6 and by the support Plate 6 is screwed with inner cylinder 11, and the middle other end of oil cylinder 10 installs supporting plate 6 and the supporting plate 6 uses screw with outer barrel 9 It is fixed.The installation drive end bearing bracket 2 blending bolt connection of the front end of outer barrel 9, drive end bearing bracket 2 are radially arranged T-shaped chute, and reshaper 1 is arranged on institute State in T-shaped chute, the outer end of reshaper 1 sets sled shape trim panel.In the course of work, in the sled shape trim panel and pipeline Wall is contacted and is slidably advanced.
The center of drive end bearing bracket 2 sets circular hole, and preceding oil cylinder 5 is arranged in outer barrel 9 and stretches out the centre bore of drive end bearing bracket 2.Preceding oil The one end of cylinder 5 is installed supporting plate 6 and the supporting plate 6 and is screwed with outer barrel 9, and pedestal 4 is simultaneously before the preceding other end of oil cylinder 5 is installed It is connected with.The other end of pedestal 4 is hinged on reshaper 1 before the one end of front strut 3 is hinged to.
The installation rear end cap 13 blending bolt connection of the end of inner cylinder 11, rear end cap 13 are radially arranged T-shaped chute, and slips 12 is installed In the T-shaped chute, arc of the end set of slips 12 with tooth.The center of rear end cap 13 sets circular hole, rear oil cylinder 15 are arranged in inner cylinder 11 and stretch out the centre bore of rear end cap 13.Afterwards the one end of oil cylinder 15 installation supporting plate 6 and the supporting plate 6 with Inner cylinder 11 is screwed, and the blending bolt of pedestal 16 connects after the rear other end of oil cylinder 15 installation.After the one end of rear pole 14 is hinged to The other end of pedestal 16 is hinged on slips 12.The outer end of pedestal 16 installation connection ring 17 afterwards, the connection ring 17 are used to connect rear end The auxiliary equipments such as hydraulic station.
Mechanical work principle of the present invention is divided into following 5 steps:
