Abstract
The invention relates to a three-edged turn drill sleeve device of a hydraulic rock drill. The three-edged turn drill sleeve device comprises a shank, a turn drill sleeve and a gear sleeve, wherein a gear is arranged outside the gear sleeve, the turn drill sleeve is connected into the gear sleeve, the end part of the shank is connected into the turn drill sleeve, the turn drill sleeve is of a triangular prism structure, the gear sleeve is internally provided with a through step hole, the big hole end of the step hole is a three-edged hole which is matched and connected with the turn drill sleeve, and the small hole end of the step hole is a cylindrical hole. The three-edged turn drill sleeve device disclosed by the invention has the advantages that a fit between an involute spline and the gear sleeve, which is adopted by the traditional turn drill sleeve for realize transmission, is changed into the fit between the triangular prism structure and the gear sleeve for realizing the transmission, thus processing is simpler; and the triangular prism structure has good mechanical properties and shock resistance, thus strength of the turn drill sleeve is greatly enhanced, the problem that the traditional turn drill sleeve is easy to fragment is well solved, fault rate of a swing mechanism is greatly reduced, and reliability of the hydraulic rock drill is improved.
Description
Technical field
The present invention relates to a kind of hydraulic gate, the triangular commentaries on classics drill sleeve of particularly a kind of hydraulic gate device.
Background technology
The manufacturing technology of external hydraulic gate is quite ripe; Like the Atlas-Copco company of Sweden, Sandvik company, Finland Tamrock company etc. all is to be devoted to hydraulic gate technical research and popularization always, and its technical level is represented the advanced level of the world today.Development at China's hydraulic gate is started late; Last century the eighties; Some types or technology from external introduction; Successively cooperate production hydraulic gate and supporting drill carriage thereof like Nanjing Engineering Machinery Plant, Shenyang Pneumatic Tools Factory, Tianshui Pneumatic Tools Plant with the Atlas-Copco company of Sweden.Xuanhua mining machinery factory, Shenyang nonferrous metallurgical equipment head factory, Lianhua Shan Mountain metallurgical machinery factory successively cooperates production hydraulic gate and supporting drill carriage thereof with French Secoma company.Owing to received the restriction of aspect conditions such as domestic raw material, technology, equipment and technology at that time, after product creates, still had a certain distance with international most advanced level.More distinct issues are that properties of product stability and reliability aspect remain further to be improved.Along with the fast development of mining industry and engineering construction industry, also increasingly high to the requirement of hydraulic gate functional performance.Usually the commentaries on classics drill sleeve in the hydraulic gate slew gear is adopted involute spline more and is cooperated with gear wheel and carry out transmission; Processing is inconvenient, and in use because moment of torsion and impact force that the commentaries on classics drill sleeve bears are very big, cracked easily; Application life is short, has a strong impact on the reliability of hydraulic gate.
Summary of the invention
The object of the invention is exactly in order to solve the weak point in the background technology, the triangular commentaries on classics drill sleeve of a kind of hydraulic gate device to be provided.
For achieving the above object, the present invention adopts following technical scheme: the triangular commentaries on classics drill sleeve of a kind of hydraulic gate device comprises bit shank, changes drill sleeve and geared sleeve; Geared sleeve is provided with the gear teeth outward, changes drill sleeve and is connected in the geared sleeve, and the end of bit shank is connected in changes in the drill sleeve; Said commentaries on classics drill sleeve is Mitsubishi's column structure; Be provided with the stepped hole of perforation in the geared sleeve, the big nose end of stepped hole is and changes the Mitsubishi hole that the drill sleeve coupling is connected that its small bore end is a cylindrical hole.
For a kind of optimization of the present invention, be provided with splined hole in the said commentaries on classics drill sleeve, the end of bit shank is connected with the splined hole coupling.
The present invention compares with background technology, has for guaranteeing hydraulic gate slew gear reliability in use, in the hydraulic gate slew gear, adopts Mitsubishi's column to change the drill sleeve structure; Tradition is changeed involute spline that drill sleeve adopts to be cooperated with gear wheel and carries out transmission and change into cooperating with gear wheel through Mitsubishi's column structure and carry out transmission; Not only make the simple of processing change, and because Mitsubishi's column structural mechanical property is good, shock resistance; Strengthened the intensity of changeing drill sleeve greatly; Solve traditional commentaries on classics drill sleeve cracked problem easily, made the fault rate of slew gear obtain very big reduction, improved the reliability of hydraulic gate; Said geared sleeve machined becomes to change the identical Mitsubishi hole of drill sleeve profile with the Mitsubishi column and cooperate with it, this structure decrease stress concentrate, shock resistance is strong, has solved the easy cracked problem of traditional commentaries on classics drill sleeve.

The specific embodiment
Embodiment 1: with reference to Fig. 1～3.The triangular commentaries on classics drill sleeve of a kind of hydraulic gate device comprises bit shank 1, changes drill sleeve 2 and geared sleeve 3, the geared sleeve 3 outer gear teeth 32 that are provided with; Changeing drill sleeve 2 is connected in the geared sleeve 3; The end of bit shank 1 is connected in changes in the drill sleeve 2, and said commentaries on classics drill sleeve 2 is Mitsubishi's column structure, is provided with the stepped hole 31 of perforation in the geared sleeve 3; The big nose end of stepped hole 31 is and changes the hole 31-1 of Mitsubishi that drill sleeve 2 couplings are connected; Its small bore end is flexible post hole 31-2, changes in the drill sleeve 2 to be provided with splined hole 21, and the end of bit shank 1 is connected with splined hole 21 couplings.During work, motor is through drive disk assembly driven gear cover 3 and triangular commentaries on classics drill sleeve 2 rotations, triangular commentaries on classics drill sleeve 2 again through and bit shank 1 between spline fitted rotate bit shank 1 and make its work.
Claims (2)
1. the triangular commentaries on classics drill sleeve of a hydraulic gate device comprises bit shank, changes drill sleeve and geared sleeve, and geared sleeve is provided with the gear teeth outward; Changeing drill sleeve is connected in the geared sleeve; The end of bit shank is connected in changes in the drill sleeve, and it is characterized in that: said commentaries on classics drill sleeve is Mitsubishi's column structure, is provided with the stepped hole of perforation in the geared sleeve; The big nose end of stepped hole is and changes the Mitsubishi hole that the drill sleeve coupling is connected that its small bore end is a cylindrical hole.
