Abstract
The utility model relates to a multifunctional underground hole making machine for pipeline construction. Compared with existing horizontal screw drillers, the hole making machine which is additionally provided with a stepped feeding mechanism has the function of two-way operations. Holes of a certain hole diameter is drilled, a circular or a rectangular hole expanding head of a bigger diameter can be replaced, so that hole expanding works can be completed when drill rods are withdrawn. A strengthening guide sleeve capable of enlarging the rigidity of the drill rods is arranged at a site where the drill rods are connected. The utility model is mainly composed of a drill, spiral drill rods, the strengthening guide sleeve, gearing devices and the stepped feeding mechanism. The utility model can be used for the construction of underground pipelines without destroying the ground surface.
Description
A kind of multi-function underground boring machine that is used for pipeline construction belongs to civil engineering construction machinery.
Domestic and international various spiral horizontal boring machine, when being used for underground pipeline construction, because be subjected to the restriction of drilling rod rigidity, along with the increase of drilling depth, and drill bit sinks gradually, when constructing in particular for comparatively loose soil property, this kind problem is particularly outstanding, has limited once mounting rig (in operating pit) and has carried out the distance that bore operation can be realized, has influenced work efficiency, and each institute hole diameter is certain, does not have the reaming function.
The multi-function underground boring machine of the present invention is intended to overcome the shortcoming of existing spiral horizontal drill.And have multiple functions such as enlarged rounded hole, rectangular opening or other shape hole, make a kind of drilling rod of diameter can produce the hole of different-diameter, down to hole greater than tens times of drill pipe diameters.Can either finish long distance boring, the hole that can produce different-diameter and different shape again.
Multi-function underground boring machine is compared with existing spiral horizontal boring machine, has increased by a step-by-step movement feed mechanism, and drilling rod and the employing of drilling rod joint can strengthen its rigidity, prevent the reinforcing guide sleeve of centerline hole deflection.Owing to adopt the step-by-step movement feed mechanism, make this rig have the function of two-way operation, promptly after finishing certain aperture boring, change its drill bit and install needed reaming head, can in returning the drilling rod process, finish ream operation than major diameter or required form (as rectangle).
The step-by-step movement feed mechanism of this boring machine mainly is made of the slide plate that is installed on the frame slide in the operating pit and be loaded on the frame slide.Several positioning holes are arranged on the frame slide, and slide plate is provided with position fixing knob and Xiao is inserted in the location, all can enter job state when slotting Xiao in location inserts in arbitrary positioning hole.The feed drive unit (being generally hydraulic jack) that is used for producing " stepping " is installed on the slide plate of step-by-step movement feed mechanism, its driveshaft is connected with the transmission device base plate of rig by joint, that is feed drive unit can drag the feeding that this machine (transmission device, drilling rod and drill bit) is realized boring.Feeding distance generally can be from 0.5 meter to several 10 meters.As long as yet the driving stroke of the feed drive unit here is no less than 0.5 meter,, the slide plate stroke on the frame slide of step-by-step movement feed mechanism and top thereof can satisfy the boring length that aforesaid once mounting operation can realize and being no less than the Run Of Steel that has the spiral material guiding channel of changing.This machine pierces soil layer by the initial position that is in the preparatory work state according to measuring good orientation during operation, its feed drive unit is whenever covered the position fixing knob that a stroke (rig pierces certain distance) moves on the slide plate and is transferred to the location to insert Xiao, make slide plate move forward a positioning hole apart from (equating substantially) with the feed distance of feed drive unit together with rig the past one positioning hole, foremost positioning hole on the frame slide, the transmission device of drilling rod and this machine is broken away from, make slide plate be retracted into initial position and located together with this machine, a drilling rod again extends, can begin the bore operation of next section, go round and begin again, until finishing predetermined hole spacing.
If institute's hole diameter has satisfied construction requirement, according to boring during feeding reverse order operate its step-by-step movement feed mechanism, can withdraw from all drilling rods and drill bit.When hole when being not enough to satisfy construction requirement and must carrying out reaming, as long as replace with the reaming head in boring terminal (next operating pit place), same operating method when returning according to drilling rod can be finished the reaming task.
The reaming head that is used to carry out reaming can design according to the shape and the bore in construction hole, and has general attaching with drilling rod.When desire need expand circular hole, can finish the reaming task of being scheduled to as long as before drilling rod is return, be replaced with the reaming head of larger aperture; When being expanded into rectangular opening, then be replaced with rectangle reaming head, or the reaming head of other combined shaped, cut native blade and be installed on cone screw plate (or swash plate) face, be shaped at the circumference of pore-forming head and cut native blade.Circular reaming head is with its knife bar rotation during operation, and the blade of non-circular reaming head such as rectangle on the cone screw face is with its auger stem rotation, it has actual being dragged by drilling rod of the reaming head of cutting native cutting edge and advances, do not rotate, not only so also to guarantee the levelness of its pore-forming, prevent to be distorted in the pore forming process.The helical blade that is installed on the drilling rod forms the spiral material guiding channel, and a suitable screw conveyor, drill bit or reaming head cut hack and deliver to hopper through " screw conveyor ", transport outside the operating pit then.
Reinforce guide sleeve and be loaded on and connect its drilling rod between two drilling rods, its external diameter equates that with the external diameter that helical blade comprised on the drilling rod its internal diameter is inserted in two drilling rod helical blades than the minor diameter place, guarantees that two drilling rods are connected to a rigid body.
The underground boring machine of this kind is owing to adopted the step-by-step movement feed mechanism, and bit change-over can be become different-diameter, difform reaming head, between drilling rod, added the reinforcing guide sleeve in addition, make this boring machine only under the situation of using a kind of specification drilling rod and drill bit, need not change a large amount of drilling rods, and a rig installation exercise by boring, expanding two-way operation, just can be produced the hole of desired aperture and desired shape and come.Its hole spacing is far longer than former spiral horizontal drill, enlarged the function of this kind rig, improved the work efficiency of underground pore-creating operation, simplified drilling tool, reduce cost, be suitable for the boring of various soil layers and lithosphere and the boring and the reaming of soil layer, can be widely used in the construction of underground utility, particularly those do not destroy under the situation on the face of land, as the underground pipeline construction in highway crossing, railway, building, riverbed.
