Abstract
A kind of pipe canopy propulsion plant, comprise connection end, right-angled intersection plug and main body, the circular end face of connection end is fixedly connected with one end of main body, and the cross end face of right-angled intersection plug is fixedly connected with the other end of main body, and described main body can be cylinder or cuboid.The utility model has the advantage of: a kind of cylinder roller bearing entity copper retainer, smoothly pipe ceiling can not only be entered accurate location, and head into by propulsion plant rotation, guarantee the quality of connection between the smooth jacking of pipe canopy and pipe canopy.
Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly a kind of pipe canopy propulsion plant.
Background technology
At present in weak broken stratum and in shallow-depth-excavation tunnel construction, in order to ensure construction safety, generally adopt leading pre-supporting technology both at home and abroad, advanced rigidity steel tube shed of constructing carries out pre-frame supporting to soft stratum, push pipe link in pipe roof construction, often causes pipe canopy progress slow, and easily occurs collapse hole or pipe fitting breakage in push pipe process, need secondary cleaning bottom of hole or retubing, affect pipe canopy quality.Adopt pipe canopy propulsion plant can guarantee pipe fitting quality, improve pipe roof construction progress, for excavation creates conditions safely and fast.
Utility model content
The purpose of this utility model is, provides a kind of pipe canopy propulsion plant, and its structure is simple, easy to use, improves efficiency of construction.
The technical scheme adopted is:
A kind of pipe canopy propulsion plant, comprise connection end, right-angled intersection plug and main body, connection end is cone, the taper seat of connection end offers screw thread, the circular end face of connection end is fixedly connected with one end of main body, right-angled intersection plug is symmetrical cross-shaped configuration, and the side cross end face of right-angled intersection plug is fixedly connected with the other end of main body.
Described main body can be cylinder or cuboid.
The utility model has the advantage of:
A kind of cylinder roller bearing entity copper retainer, can not only enter accurate location by pipe ceiling smoothly, and heads into by propulsion plant rotation, guarantees the quality of connection between the smooth jacking of pipe canopy and pipe canopy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation connected between pipe canopy.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of pipe canopy propulsion plant, comprise connection end 1, right-angled intersection plug 2 and main body 3, connection end 1 is cone, the taper seat of connection end 1 offers screw thread, the circular end face of connection end 1 is fixedly connected with one end of main body 3, right-angled intersection plug 2 is symmetrical cross-shaped configuration, and the cross end face of right-angled intersection plug 2 is fixedly connected with the other end of main body.
Adopt pipe canopy rig by after hole depth drilling to completion, laid down by pipe canopy drill bit, change pipe canopy drill bit propeller system for this reason, pipe canopy rig is connected with connection end 1.
Every root pipe canopy 4 termination is all processed with right-angled intersection draw-in groove, and snapped in by right-angled intersection plug 2 in the reserved cross clamping groove of every root pipe canopy 4, propulsion plant can just withstand the end of pipe canopy 4.
Under pipe canopy rig power, adopt rotation and percussion directly to head in hole by the body of each root pipe canopy 4 by pipe canopy propeller, inner sleeve 5 connects by inside, Guan Peng side, the docking of two cross clamping grooves, then adopt electric welding by inner sleeve 5 and pipe canopy 4 all welded together.
So, pipe canopy is constructed one by one, and in the draw-in groove of last root pipe canopy, connection end 1 just can withstand the end of the body of pipe canopy 4, accelerates the speed of pipe canopy 4 times pipes like this, ensure that the welding quality of pipe canopy 4.
