Abstract
The utility model discloses a kind of churning driven elevator, comprise connector, cylindrical shell, bearing and end cap, upper connector and 5 bearing fits, by hold-down nut axial restraint.Hold-down nut and upper connector are fixed by screw at end face, cylindrical shell and bearing fit, and cylindrical shell is connected by screw and spring shim with end cap, bearing in cylindrical shell by the shaft shoulder and end cap axial location.Realize a structure simply by rotary motion being separated, convenient and reliable churning driven carries leading-in device, reduces the wearing and tearing of master winch wire rope, improves application life.To the construction cost reducing rotary drilling rig user, the cost of labor comprising the cost of raw materials used of wire rope and more change steel rope is significant.
Description
Technical field
The utility model relates to a kind of churning driven and carries leading-in device.
Background technology
At present, rotary drilling rig, as a kind of construction machinery being adapted at pore-forming operation in building foundation engineering, is widely used in the foundation construction engineerings such as urban construction, highway bridge, highrise building.Installed power is large, output torque is large, axial compression is large, maneuverability owing to having for rotary drilling rig, the advantages such as the high and hole quality of efficiency of construction is good, obtain in engineering construction field and use widely, become the main pore-forming equipment of engineering construction, simultaneously, rotary drilling rig can also by coordinating from various different drilling tool, be applied to dry type (coordinating with short spiral drill), or the pore-forming operation of wet type (coordinating with rotary bucket) and rock stratum (coordinating with rock core drill).In practical work process, the drilling rod of the rotary drilling rig lifted by wire rope drives drill bit rotational, realizes pore-forming object.But in order to overcome in drilling rod lifting process, the rotation of drilling rod is passed to wire rope, makes wire rope bear torsion force, finally causes wire rope to be cut off.
Summary of the invention
For the deficiencies in the prior art, now provide a kind of churning driven to carry leading-in device, be intended to the wearing and tearing reducing wire rope, and then improve its application life, reduce the construction cost of rotary drilling rig user.
Technical scheme adopted to achieve these goals: a kind of churning driven elevator, comprise connector, cylindrical shell, bearing and end cap, upper connector and 5 bearing fits, by hold-down nut axial restraint, hold-down nut and upper connector are fixed by screw at end face, cylindrical shell and bearing fit, cylindrical shell is connected by hold-down screw and spring shim with end cap, bearing in cylindrical shell by the shaft shoulder and end cap axial location.
Further, upper connector and end cap are provided with oil sealing sealing at the place of relatively rotating, and cylindrical shell is provided with oil filler point, by being provided with the lubricating cup sealing of pad.
Further, 5 bearings be connected with upper connector are angular contact bearings, and a bearing wherein away from hold-down nut is installed dorsad.
The beneficial effects of the utility model are, realize a structure simply by rotary motion being separated, convenient and reliable churning driven carries leading-in device, reduces the wearing and tearing of master winch wire rope, improves application life.To the construction cost reducing rotary drilling rig user, the cost of labor comprising the cost of raw materials used of wire rope and more change steel rope is significant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. go up connector, 2. hold-down screw, 3. spring shim, 4. end cap, 5. oil sealing, 6. cylindrical shell, 7. bearing, 8. hold-down nut, 9. screw, 10. lubricating cup, 11. pads.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In FIG, a kind of churning driven elevator, comprise connector 1, cylindrical shell 6, bearing 7 and end cap 4, upper connector 1 coordinates with 5 bearings 7, by hold-down nut 8 axial restraint, hold-down nut 8 is fixed by screw 9 at end face with upper connector 1, cylindrical shell 6 coordinates with bearing 7, and cylindrical shell 6 is connected by hold-down screw 2 and spring shim 3 with end cap 4, bearing 7 in cylindrical shell 6 by the shaft shoulder and end cap 4 axial location.
Its basic ideas are: upper connector 1 is provided with bearing installation shaft, axle tail is provided with bearing hold-down nut, axle head is provided with nut anti-looseness screw, cylindrical shell 6 inside is provided with bearing mounting hole, the location shaft shoulder is provided with in installing hole, cylindrical shell and bearing fit, cylindrical shell 6 tail end face installs end cap 4, is connected with cylindrical shell 6 hold-down screw 2.
Further, be deep in the mud of very dark (nearly 80 meters) because elevator needs to follow rotary drill tools, now the pressure of elevator outside is very large, under the effect of the pressure, mud may enter into the inside of elevator, damages elevator component.Upper connector 1 is provided with oil sealing 5 with end cap 4 and seals at the place of relatively rotating, cylindrical shell 6 is provided with oil filler point, is sealed by the lubricating cup 10 being provided with pad 11.Upper connector is connected with between cylindrical shell can be relatively rotated by bearing, and upper connector and cylindrical shell axial direction are fixed by the shaft shoulder and end cap.Achieve the object that lifter motion is separated with rotary motion.
Further, 5 bearings 7 be connected with upper connector 1 are angular contact bearings, and a bearing wherein away from hold-down nut 8 is installed dorsad.With strengthen bearing reply bearing axle to active force, bearing can bear bi-directional axial load, and the performance of bearing overturning moment is good.
