Embodiment Construction

[0014] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0015] In the figure, a coaxial double-reduction forward and reverse bidirectional output helical rock drilling rig includes a double-input motor 1, a double-input shaft 2, a center wheel 3, a planetary wheel 4, a ring plate inner ring gear 5, a ring plate 6, and an eccentric bearing 7 , Outer casing 8, hollow output shaft 9, evenly distributed planetary gear 10, planetary wheel shaft 11 and outer casing inner ring gear 12. The hollow output shaft 9 is fixedly connected with a planetary gear 4, and the planetary gear 4 meshes with the inner ring gear 5 of the ring plate connected in the central hole of the ring plate 6, and the two outer circles on the left and right sides of the ring plate 6 are symmetrical The hole is connected to the double input shaft 2 through the single-row tapered roller eccentric bearing 7, and the input motor 1 is r...

Abstract

The invention relates to a coaxial double speed reduction forward and inverted bidirectional output spiral rock-entering drilling machine which comprises double input shafts, four groups of ring plate speed reduction devices, a hollow output shaft, an outer sleeve and a planetary reduction gear. Each ring plate speed reduction device comprises a ring plate, an eccentric bearing and a ring-plate inner gear ring; each ring-plate inner gear ring is arranged in a center round hole of the corresponding ring plate and is meshed with a planet gear connected with the hollow output shaft; each eccentric bearing is arranged in symmetrical round holes at both sides of the corresponding ring plates and is connected in series with the double input shafts; the outer sleeve is coaxially sleeved with the hollow output shaft; the planetary reduction gear comprises a center wheel connected to the hollow output shaft and a uniformly distributed planet gear meshed with the center wheel; the uniformly distributed planet gear is meshed with an inner gear ring of the outer sleeve.

Description

technical field [0001] The invention relates to the field of rock entry equipment for long auger drilling rigs, in particular to a coaxial double deceleration forward and reverse bidirectional output helical entry drilling rig. Background technique [0002] Nowadays, many piles require that the piles must be inserted into the rock in order to ensure high bearing capacity. The rock entry equipment currently used in my country is very backward, basically percussion drilling, with low efficiency and serious mud pollution. China Shanhe Intelligent Equipment Co., Ltd.’s invention patent separate-drive casing auger and its construction method (ZL 200610138353.3) discloses the deceleration drive technology as follows: (1) The inner power head and the outer power head: the former is at the top, and the latter At the bottom, the two power heads are set separately; (2) The driving devices of the inner and outer power heads both adopt dual-motor two-stage NGW planetary reduction, and t...
