Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, this utility model is described in detail.
nullAs illustrated in fig. 1 and 2，The crawler expanding mechanism of one rig is repaired in a kind of soil sample，Including directive wheel 1，Guide pad 8 and tensioning hydro-cylinder 12，Described directive wheel 1 is positioned at tensioner guide wheel assemblies foremost，And be connected on described guide pad 8 by directive wheel main shaft 4，Equipped with lining 5 and flanger bearing bush 6 between described directive wheel 1 and described directive wheel main shaft 4，Described directive wheel 1 both sides are provided with side cover 2，Described side cover 2 is middle with described directive wheel 1 equipped with float grease seal 3，Described directive wheel main shaft 4 is fixed by pin 7，Described guide pad 8 rear end is furnished with screwed hole and can be bolted pushing block 9，Described pushing block 9 central aperture places piston rod 11，By bolt and back-up ring 10, described piston rod 11 is fixed on described pushing block 9，The rear end of described tensioner guide wheel assemblies is provided with pressure ring 14，Described tensioning hydro-cylinder 12 afterbody passes described pressure ring 14，It is cased with buffer spring 13 on described tensioning hydro-cylinder 12.
Preferably, described directive wheel 1 is driven pulley, for orifice-plate type, anodontia.
Further, described tensioning hydro-cylinder 12 is made up of two parts, leading portion front end is provided with boss, rear portion is provided with internal thread hole, and back segment hollow is designed with external screw thread as oil circuit, two ends, back segment front end is threaded connection with leading portion rear end, and reinforcement of weld, back segment rear threads spins adjusting nut 15, and afterbody is equipped with playing chain nozzle assembly 16.
