Abstract
The utility model relates to a novel vise roller mechanism of a horizontal directional drilling machine. The mechanism comprises a fixed plate, a roller, a sleeve, a bolt, a front baffle, a hollow bolt, an annular barrel, a grease fitting and the like, wherein the fixed plate is arranged on a vise body by the bolt, the front baffle is connected with the fixed plate through the bolt and the hollow bolt, the sleeve is sleeved on the bolt and is compacted between the fixed plate and the front baffle through the bolt, the roller is sleeved on the hollow bolt and is arranged between the fixed plate and the front baffle, the annular barrel is arranged on the surface of an internal cylinder formed by the roller, and the grease fitting is arranged on the hollow bolt. In working, a drill rod is directly contacted with the annular barrel, and because the annular barrel and the roller can roll relatively, the friction between the drill rod and a single roller is converted into the friction between the drill rod and the annular barrel and the friction between the annular barrel and a plurality of rollers, so that the contact stress of the roller is reduced, the abrasion of the roller is reduced, and the service life of the roller is prolonged. The novel vise roller mechanism has the advantages that the friction between the drill rod and the single roller is avoided, the abrasion of the roller is relieved, and the service life of a vise is prolonged.
Description
Technical field
The utility model relates to the novel vice idler wheel mechanism of the idler wheel mechanism that uses on a kind of rig, particularly a kind of horizontal directional drilling machine.
Background technology
Vice is the key components and parts of horizontal directional drilling machine, and its performance quality directly has influence on the performance of horizontal directional drilling machine functional performance.In the work progress of horizontal directional drilling machine, need frequently utilize vice to install or dismounting drilling rod.In the course of the work, drilling rod rotates with respect to vice, and drilling rod and vice roller rub, and the time one is long, and the premature wear of roller not only can take place, and also can cause the wearing and tearing of drilling rod, reduces the application life of drilling rod, even can cause serious construction accident.
The utility model content
The purpose of the utility model is to provide a kind of: simple in structure, and drilling rod is not rubbed with roller, and the novel vice idler wheel mechanism of the drilling rod that do not wear and tear.
The purpose of the utility model is achieved in that this mechanism comprises fixed head, roller, sleeve, bolt, front apron, hollow bolt and grease nipple; Fixed head is fixed by bolts on the vice body; Front apron is connected with fixed head through bolt and hollow bolt, and sleeve is through on the bolt, and sleeve is pressed between fixed head and the front apron through bolt; Roller is through on the hollow bolt; Roller is installed between fixed head and the front apron, and the ring-type tube is installed in the formed inner periphery of roller, and grease nipple is installed on the hollow bolt.
Described ring-type tube is that an external surface has groove, and inner surface has the cylindrical body of chamfering.
Described hollow bolt is the bolt that there is oilhole at a middle part, and the turret head of bolt partly has screwed hole.
Beneficial effect, owing to adopted such scheme, drilling rod directly contacts with the ring-type tube when work; Drilling rod drives the ring-type tube and rotates; Because the ring-type tube contacts with a plurality of rollers, convert drilling rod into and contact thereby original drilling rod contacted with single roller with a plurality of rollers, reduced contact stress; Reduce drilling rod and rolling wheel wear, prolonged the application life of vice and drilling rod.In addition, can reduce user's use and maintenance cost, simple in structure, drilling rod can not rubbed, and the drilling rod that do not wear and tear with single roller, reach the purpose of the utility model.
Advantage: avoided drilling rod to contact, alleviated the wearing and tearing of drilling rod and roller, prolonged the application life of roller, drilling rod with single roller.
