Title:
BREAKING HAMMER HAVING POLARIZED DRILL ROD
Document Type and Number:
WIPO Patent Application WO/2018/032543
Kind Code:
A1
Abstract:
Provided is a breaking hammer having a polarized drill rod, comprising a polarization motor (3), a speed reducer (4), a polarization gear (6), a first drill rod (1), a second drill rod (7), a drill-rod straight sleeve (2), a drill-rod expanding sleeve (14), a Cardan joint (18), a Cardan ring (28), an annular rotating ring (19); the drill-rod straight sleeve (2) is connected to the drill-rod expanding sleeve (14), and the first drill rod (1) and second drill rod (7) are connected by means of the Cardan joint (18); the first drill rod (1) is installed inside the drill-rod straight sleeve (2), and the second drill rod (7) is installed in the Cardan ring (28); the Cardan ring is installed on the inner edge of the annular rotating ring (19) by means of a plain bearing (26); the polarization motor (3) and polarization gear (6) may cause the annular rotating ring (19) to rotate, resulting in polarization; the fitting of the annular rotating ring (19) and the Cardan ring (28) drives the second drill rod (7) to oscillate in the drill-rod expanding sleeve (14); the breaking hammer having a polarized drill rod has a simple structure; the annular rotating ring (19) and the Cardan ring (28) cause the second drill rod (7) to oscillate eccentrically; broken objects are separated from the point of breakage by way of the second drill rod (7) such that there is a better field of view around the point of breakage, and thus functional performance is relatively good.
