Abstract
The invention relates to a slewing bearing of a full-bushing full-slewing drilling machine. The slewing bearing comprises a lower outer ring, pin rollers, an upper outer ring and an inner ring, wherein the lower outer ring and the upper outer ring are positioned outside the inner ring to commonly surround the inner ring, a rotating flange is formed on the periphery of the inner ring, pin roller slots capable of accommodating the pin rollers are formed above the rotating flange, under the rotating flange and outside the rotating flange as well as between the lower outer ring and the upper outer ring. The service life of the slewing bearing is long. Due to the bearing capacity test, the slewing bearing of the full-bushing full-slewing drilling machine provided by the invention has high bearing capacity.
Description
Technical field
The present invention relates to a kind of pivoting support, relate in particular to the pivoting support that uses on the full-sleeve full-rotation drill.
Background technique
Continuous quickening along with China's infrastructure, construction under the various complicated geological environments such as plateau, mountain area, hills, seabeach, rivers,lakes and seas beach is more and more, often run into the underground drift sand that has during site operation, the various complicated geological situations such as solution cavity, rock stratum, traditional excavation facility and method of construction are difficult to construction.Occurred in recent years full-sleeve full-rotation drill both at home and abroad, and adopted ball as roll piece in the pivoting support, and caused the pivoting support load force little, the life-span is short, is difficult to satisfy actual requirement of engineering.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the pivoting support of the larger full-sleeve full-rotation drill of a kind of load force.
A kind of pivoting support of full-sleeve full-rotation drill, it comprises: lower outer ring, roller, upper outer ring and inner ring, lower outer ring and upper outer ring are positioned at the inner ring outside and jointly inner ring are surrounded, inner ring is formed with rotating flange in periphery, and this rotating flange up, be formed with the roller slot that holds roller between below and the outside and lower outer ring and the upper outer ring.Longer service life.
Behind test of bearing capacity, the pivoting support of full-sleeve full-rotation drill of the present invention has larger bearing capacity.
Description of drawings
Fig. 1 is the sectional drawing of the pivoting support of full-sleeve full-rotation drill of the present invention;
Fig. 2 is the plan view of the pivoting support of full-sleeve full-rotation drill of the present invention;
Fig. 3 is the cracking figure of the pivoting support of full-sleeve full-rotation drill of the present invention.
Among the figure: 1, lower outer ring, 2, roller, 3, upper outer ring, 4, inner ring.
Embodiment
See also Fig. 1 and Fig. 2, the pivoting support of full-sleeve full-rotation drill of the present invention comprises lower outer ring 1, upper outer ring 3, roller 2 and inner ring 4.Wherein, lower outer ring 1 is positioned at inner ring 4 outsides with upper outer ring 3, jointly inner ring 4 is surrounded.Inner ring 4 is formed with rotating flange in periphery, is formed with roller slot between the top of rotating flange, below and the outside and lower outer ring 1 and the upper outer ring 3.Each one in the upside of rotating flange, downside and the outside amount to three roller slots, are used for holding roller 2.Roller 2 is cylindrical body, and smooth surface is arranged in the roller slot, and the friction between inner ring 4 and lower outer ring 1, the upper outer ring 3 is converted into rolling friction, the power of reducing friction.See also Fig. 3, Fig. 3 is the in working order lower test that the pivoting support of full-sleeve full-rotation drill of the present invention is done.Wherein, bearing capacity is adjusted in such a way:
(1) by static operating mode type selecting
F’a=Fa?fs=500×104×1.25=625×104N·m
M’=Mfs=100×104×1.25=125×104N·m
(2) check the life-span by dynamic operating mode
F’a=Fa?fd
=500×104×1.45=725×104N·m
M’=Mfd
=100×104×1.45=145×104N·m
F ' a in the formula---pivoting support equivalent central axial force, unit: N;
M '---pivoting support equivalent tilting moment, unit: Nm;
Safety coefficient under the static operating mode of Fs---pivoting support;
Fd---the safety coefficient under the pivoting support dynamic operation condition.
By the active force type selecting of bearing under the static operating mode and check construction bolt intensity, check the life-span by the active force that bears under the dynamic operating mode.
(see figure 3) in the bearing capacity plotted curve of selected pivoting support is looked for a little with the above F ' a that calculates and M ', when this point is positioned at the bearing capacity curve when following, illustrates that this pivoting support meets the demands.
Curve 1 is the static bearing capacity curve among the figure, and curve 2 is the dynamic carrying capacity curve, and curve 8.8,10.9,12.9 is 8.8 grades, 10.9 grades, the bearing capacity curve of 12.9 grade bolt materials.
Above test result shows that the pivoting support of full-sleeve full-rotation drill of the present invention is rational in infrastructure, and load force is large, can bear simultaneously various load, has prolonged the machine works life-span.
Claims (2)
1. the pivoting support of a full-sleeve full-rotation drill, it comprises: lower outer ring, roller, upper outer ring and inner ring, lower outer ring and upper outer ring are positioned at the inner ring outside and jointly inner ring are surrounded, inner ring is formed with rotating flange in periphery, and this rotating flange up, be formed with the roller slot that holds roller between below and the outside and lower outer ring and the upper outer ring.
2. the pivoting support of full-sleeve full-rotation drill as claimed in claim 1 is characterized in that, this roller slot is used for holding columniform roller.
