Abstract
The utility model relates to a telescopic drilling rod arranged on pile-driving equipment while in the pile driving in the building engineering. An inner rod is arranged in an outer rod; the upper part and the lower part of the outer rod are provided with at least two guide wheels; the upper part of the outer rod is provided with an arrangement body whose both ends are provided with sliding parts sliding along a drill rig and leading chains fixed with the sliding parts. The utility model has simple structure, and wide usage. The utility model can be caused to drive various pile foundations on one pile-driving equipment.
Description
The utility model relates to a kind of telescopic drill rod that piling the time is used in construction work on pile driving equipment.
At present mostly the drilling rod in the pile driving equipment is to fix, not flexible, and construction depth is restricted, and purposes is single, as the drilling rod of beating rotary churning pile just can't beat hole digging pile, promptly is existing scalable drilling rod, because its structure unreasonable, can't pumped (conveying) medium, use unsatisfactory.
The purpose of this utility model just provides a kind of novel telescopic drill rod, can solve the problem that needs of beating multiple pile foundation effectively.
The purpose of this utility model is achieved like this, adorn bar outside in interior bar outside, between inside and outside bar fixing sliding sealing device is arranged, interior bar slides in the bar outside vertically, but and coaxial rotation, outer bar upper and lower part has two guide wheels at least, and is connected by attachment (as leading chain or wire rope), the device body is arranged at outer bar top, above the device body medium transport pipe is arranged.
The utility model novel structure, simple, purposes is wide, can make it can beat the pile foundation of multiple multiclass on a pile driving equipment, has the wide market of applying, and economic worth is huge.
Below knot elaborates to structure of the present utility model to accompanying drawing.
Accompanying drawing is a section of structure of the present utility model.
Provide by accompanying drawing, so its structure of the utility model is by interior bar, the device body on outer bar and top constitutes, the interior bar 2 that slides is vertically arranged in the outer bar 1, and with outer bar 1 coaxial rotation, outer bar 1 upper and lower is equipped with two guide wheels 4 at least, and be slidingly connected by guide wheel rope 3, in the realization, stretching of outer bar, there is device body 5 outer bar 1 upper end, between device body 5 and the outer bar 1 tumbler 10 (as bearing) is housed, device body 5 two ends have the sliding part 13 that slides along drilling cramp and by fixture 12 fixing lead chain 11, lead 5 slips of chain 11 drive device bodies, medium transport pipe 8 is arranged at device body 5 tops, and fixedly connected by flange 9, guide wheel rope 3 is equipped with sealing device 14 with the exit of outer bar 1, between the top of interior bar 2 and outer bar 1 inwall sliding sealing device 6 is housed, the parts 7 that stator ring rope 3 is arranged on it, bar 2 slided in guide wheel rope 3 drove.Be its requirements of one's work, can remove medium transport pipe 8 sometimes, that is to say on the device body 5 and can be equipped with or cancel medium transport pipe 8, when cancellation medium transport pipe 8, its corresponding parts all can save.
The utility model only needs sliding part 13 is contained on the former drilling cramp and gets final product in use.The utility model is applicable to have the pile driving equipment that rotating disk drives drilling rod, when device body 5 with leading chain 11 when moving, at this moment, interior bar 2 and outer bar 1 move along a direction simultaneously, main suitable beat borehole pile foundation and slurries retaining wall drill-pouring pile foundation, borehole pile foundation comprise bucket borehole, short spiral borehole and short spiral and the compound borehole of bucket.
