Abstract
The utility model regards to a drilling rig, in particular to an inclined hole drilling rig which can drill the large diameter inclined hole. A drilling cramp whose gradient can be adjusted by the hydrocylinder which is arranged on the front of the body of the drilling rig; a drilling stem which is arranged in the drilling cramp can be extended and shortened link-by-link; the drilling stem looks like a hanging TV telescopic antenna with a large diameter; a diving power head is connected under the drilling stem; the drilling bit is arranged under the power head, which is a combined drill composed of the pointed rod of the twist drill and the body of the lantern drill; a guide frame whose center height can be counted by the clinometer and can be adjusted by the hydrocylinder. With the structure mentioned above, the drilling rig can easily drill out the inclined hole which accords with the design requirement.
Description
The utility model is about rig, the particularly a kind of invention that can bore the rig of major diameter inclined hole.
Bored pile is because it has more advantage, closely during the last ten years, in bridge, water conservancy, industry and civilian construction, generally adopted, and the potential economic benefit of inclined borehole stake is considerable, obtaining increasing people in recent years and pay attention to, is a new technology that wide use prospect is arranged.But perfect inadequately because of boring machine, technology is not really ripe, and the pile gradient is difficult for guaranteeing, so be not used widely so far.
Analyze known various rigs, when they executed rat holing, the guidance mode of its control gradient had two big classes, one class is by rig self tilting gearing, rely on the rigidity orientation of drilling cramp drilling rod, its drilling rod mostly is that the garden bar of same diameter utilizes various joint, by saving spreading to Len req.This class rig is when they execute rat holing, because the amount of deflection of drilling rod, the boring gradient reduces along with the increase of hole depth, and gradient diminishes gradually, thereby does not satisfy designing requirement.Another kind of guidance mode comprises tiretube process, guide cylinder method and guide pipe interior orientation method etc.It is huge that wherein tiretube process uses plant equipment, and the cost height is difficult for promoting.The guide cylinder of guide cylinder method is contained on the drilling rod and rotates with drilling rod, always the diameter of guide cylinder is slightly more a little bit smaller than the aperture.Along with the growth of drilling rod, the amount of deflection of drilling rod increases gradually, still has bigger error with this very not reliable intermediate support point, pore-forming gradient.Guide pipe interior orientation method is guide pipe to be anchored in the soil body by the requirement of stake axis with geological drilling rig earlier, bigger drill sleeve is carried over this bar outside and executes brill.Though this method can obtain satisfactory inclined hole, operation is various, and efficient is not high, and guide pipe is also easy to wear.
Task of the present utility model provides a kind of driller, and it can successfully get out the inclined hole that adheres to specification.
Task of the present invention is finished as follows: this rig body forward structure is equipped with a gradient can be by the drilling cramp of hydraulic cylinder adjustment.A telescopic drill rod that plays and can slide up and down with wire rope is arranged in the drilling cramp, and this drilling rod is that the garden pipe box dress that is not waited by the more piece diameter forms, and it can and shorten by the joint elongation, resembles a large diameter television set that is hanging upside down and draws and defend antenna.The drilling rod lower end unit head of then diving under water, drill bit is being adorned in the unit head lower end.
Another improvement of the present invention is: it uses a kind of combined drill, is to be combined by the sharp bar of auger and main body two parts of lantern brill.The effect of point bar is to set up a supporting-point at the drill main body front end, and the guiding drill bit is along straight ahead.
The present invention also has an improvement to be: in drilling rod bottom one side the leading truck that highly can adjust with hydraulic cylinder at any time is housed, the foundation of adjusting the leading truck height is to be contained in the reading that inclinometer on the unit head is reflected to pulpit, sometimes the leading truck height is larger than into pore radius, with the influence that compensation drilling rod amount of deflection produces, the base area of leading truck ship shape is wanted suitably.Can hold with hole wall soil and to can stand to its pressure unlikely slump and be advisable.
Telescopic drill rod submersible type inclined drill has following advantage:
1. the elongation of drilling rod and shorten is quick and conveniently compared the time that can save connecting and disconnecting drill rod with known rig, alleviates working strength of workers, can improve drilling efficiency.
2. this rig is compared with known rig, and structure is simpler, and is easy to manufacture, easy to use, can abate the noise, and its complete machine cost is lower than rig of the same type.
3. this rig can be executed rat holing, also can bore straight hole with it, and efficient can be higher.When boring straight hole, can pull down leading truck, combined drill be changed into common drill bit, in order to avoid make them be subjected to unnecessary wearing and tearing.
Accompanying drawing has been described one embodiment of the present of invention.
Accompanying drawing 1: the lateral view of telescopic drill rod submersible type inclined borehole rig when executing rat holing;
Accompanying drawing 2: the front elevation drawing of telescopic drill rod.
