Abstract
The invention discloses a caterpillar band tensioning mechanism for a soil sampling and repairing integrated drilling machine. The caterpillar band tensioning mechanism comprises a guide wheel, a guide block and a tensioning oil cylinder. The guide wheel is located at the forefront end of a tensioning guide wheel assembly and connected to the guide block through a guide wheel spindle. A lining and a folded edge shaft sleeve are arranged between the guide wheel and the guide wheel spindle. Side covers are arranged on the two sides of the guide wheel. Floating oil seals are arranged between the side covers and the middle of the guide wheel. The guide wheel spindle is fixed through a pin. Threaded holes are distributed in the rear end of the guide block so that the guide block can be connected with a push block through bolts. A hole is formed in the middle of the push block to contain a piston rod. The piston rod is fixed to the push block through the bolts and a check ring. A press ring is arranged at the rear end of the tensioning guide wheel assembly. The tail of the tensioning oil cylinder penetrates the press ring. The tensioning oil cylinder is sleeved with a buffer spring. By the adoption of the caterpillar band tensioning mechanism, the situation that a caterpillar band is too tight or too loose can be effectively prevented, and the tightness of the caterpillar band can be adjusted; the oil cylinder is sleeved with the buffer spring, so that space is saved, meanwhile, the oil cylinder is used for guidance, and the structure is convenient and simple; and a tensioning wheel is arranged on a driven wheel, the complexity of the mechanism can be lowered, and maintenance, disassembly and assembly are convenient.
Description
Technical field

It is an object of the invention to the problem above overcoming prior art to exist, a kind of soil sample is provided to repair the crawler expanding mechanism of one rig, enable to two kinds of difference in functionality unit head quick-replaceables use, and realize center of rotation zero error, realize a machine Alternative arrangement and method for construction, significantly reduce rig limitation, improve rig economy, versatility.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
The crawler expanding mechanism of one rig is repaired in a kind of soil sample, including directive wheel, guide pad and tensioning hydro-cylinder, described directive wheel is positioned at tensioner guide wheel assemblies foremost, and be connected on described guide pad by directive wheel main shaft, equipped with lining and flanger bearing bush between described directive wheel and described directive wheel main shaft, described directive wheel both sides are provided with side cover, equipped with float grease seal in the middle of described side cover and described directive wheel, described directive wheel main shaft is fixed by pin, described guide pad rear end is furnished with screwed hole can be bolted pushing block, described pushing block central aperture places piston rod, by bolt and back-up ring, described piston rod is fixed on described pushing block, the rear end of described tensioner guide wheel assemblies is provided with pressure ring, described tensioning hydro-cylinder afterbody passes described pressure ring, it is cased with buffer spring on described tensioning hydro-cylinder.
Preferably, described directive wheel is driven pulley, for orifice-plate type, anodontia.
Further, described tensioning hydro-cylinder 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, and afterbody is equipped with playing chain nozzle assembly.
Further, described buffer spring is crushed in the middle of described tensioning hydro-cylinder front end boss and described pressure ring.
Beneficial effects of the present invention:
The present invention can effectively prevent crawler belt the tightliest or the most loose situation, and crawler belt tighting degree is adjustable；Buffer spring is enclosed within oil cylinder, not only saves space, utilizes oil cylinder to be used as to guide simultaneously, and structure is convenient and simple；Expansion tightening wheel is arranged on driven pulley, it is possible to decrease mechanical complications, makes maintenance easy accessibility.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention 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.
