Description
Technical field
The utility model relates to a kind of geological prospecting equipment, particularly a kind of non-dredging guiding driller drill rod centering device.
Background technology
Non-dredging guiding driller is that China is near during the last ten years, grows up based on the New Equipments of underground pipeline layout engineering, be mainly used at present communication, electric power, coal gas and tap water pipeline non-excavation laying construct.Erection device is very important parts in such rig, generally be installed on the front end of clamp unscrewing device, during drilling machine construction, drilling rod plays supporting and guide effect by this device guiding hole, the reliability of this device and robustness, be directly connected to drilling rod when creeping into, the stability of drilling tool and the accuracy of pore-forming, affect righting effect when clamp unscrewing, replacing drilling rod simultaneously, visible its unfailing performance of guarantee is extremely important.When but existing rig is constructed at the scene, the active force reaching this device through drilling rod is very large, rolling wheel support effect is very easily made to be out of shape, so and for a long time, erection device is due to its structural factor, rolling wheel support rigidity seems not enough, the distortion of rolling wheel support and the excessive wear of roller when this major embodiment meets that bad ground is stressed sharply to be become large in constructing, as can be seen from this, when there is this situation, the righting of equipment and steering capability can be deteriorated rapidly, the rotary jumping amount of drilling rod also will become large immediately, and directly affect the normal construction of rig.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of good rigidly, structure is simple, reasonable in design, can strengthen the non-dredging guiding driller drill rod centering device of Whole Equipment reliability.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of non-dredging guiding driller drill rod centering device, be characterized in: comprise the supporting positive cover be sleeved on outside drilling rod, supporting positive cover is connected with the adpting flange of rig clamp unscrewing device by roller wheel bearing mechanism, described roller wheel bearing mechanism comprises turning rolls and is evenly arranged on by roller shaft circumference some supporting rollerns turning rolls supporting supporting positive cover, the axis of roller shaft and the axis of supporting positive cover be arranged in parallel, described turning rolls forms by turning rolls front mud pan with the turning rolls rear flange that rig clamp unscrewing device adpting flange is fixedly connected, the mounting groove installing supporting rollern is formed between turning rolls front mud pan and turning rolls rear flange, described supporting rollern is arranged in mounting groove, the outer wall of supporting positive cover is provided with the setting circle annular groove that a circle coordinates with supporting rollern.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and the groove depth of described setting circle annular groove is less than the radius of supporting rollern.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described supporting positive cover and drilling rod are coaxially arranged.
Compared with prior art, the utility model utilizes the outer supporting positive cover be enclosed within drilling rod to be connected with the adpting flange of rig clamp unscrewing device by roller wheel bearing mechanism, enhances the ability of the overall resistance to deformation of device greatly, thus compensate for local stiffness deficiency on the weak side; Utilize the turning rolls rear flange be fixedly connected with rig clamp unscrewing device adpting flange, increase contact area, ensure that the unfailing performance of installation; Utilize turning rolls front mud pan, reduce when supporting rollern rotates and be subject to mud water mitigation, reduce the wearing and tearing because influence to sediment causes.The utility model structure is simple, reasonable in design, manufacture even easily, cost is low, installation and maintenance are convenient, has promotion and application value in middle-size and small-size non-dredging guiding driller.

Detailed description of the invention
A kind of non-dredging guiding driller drill rod centering device, comprise the supporting positive cover 2 be sleeved on outside drilling rod, supporting positive cover is connected with the adpting flange 1 of rig clamp unscrewing device by roller wheel bearing mechanism, described roller wheel bearing mechanism is comprised turning rolls and is evenly arranged on the some supporting rollerns 4 turning rolls supporting supporting positive cover by roller shaft 5 circumference, the axis of roller shaft 5 and the axis of supporting positive cover be arranged in parallel, described turning rolls forms by turning rolls front mud pan 6 with the turning rolls rear flange 3 that rig clamp unscrewing device adpting flange 1 is fixedly connected, the mounting groove installing supporting rollern is formed between turning rolls front mud pan 6 and turning rolls rear flange 3, described supporting rollern 4 is arranged in mounting groove, the outer wall of supporting positive cover 2 is provided with the setting circle annular groove that a circle coordinates with supporting rollern.Described turning rolls adopts integral assembly welding structure design, enhance the ability of overall resistance to deformation greatly, thus compensate for local stiffness deficiency on the weak side, utilize the large plane positioning of adpting flange (installation base surface), contact area is large, install reliable, each connecting bolt uniform force, the ability that turning rolls entirety bears resistance to deformation has larger enhancing.Drilling rod (being generally not less than three meters) one end that described non-dredging guiding driller is longer and main shaft are connected, other end cylindrical is then supported in supporting positive cover, when main shaft rotate moment of torsion passed to drilling rod make it to rotate time, this device plays supporting to the drilling rod be positioned at wherein, righting and guide effect, described the utility model supporting positive cover center and rig clamp unscrewing device center, alignment of shafts level is coaxially arranged, simultaneously supporting positive cover with drilling rod around coaxial center rotating Vortex, and supporting rollern 4 does the rotation reverse with supporting positive cover around roller shaft 5 in original place, when changing slip shackle, play supporting, righting and positioning action.
The groove depth of described setting circle annular groove is less than the radius of supporting rollern; Described supporting positive cover and drilling rod are coaxially arranged.Described supporting rollern to be loaded on roller shaft and to be uniformly distributed in the mounting groove of turning rolls, described supporting positive cover is then by outer wall setting circle annular groove supporting six, location supporting rollern, supporting rollern is as supporting positive cover positioning support, stressed comparatively even, therefore in working, the over worn situation of indivedual supporting rollerns obviously reduces, and unfailing performance is obviously promoted.The roller shaft alloy steel of described supporting rollern heat treatment quenching and tempering, flexural strength is large, can ensure that rig does not occur bending and deformation when maximum construction ability.Article six, high-strength bolt makes this device be connected in the front end of rig clamp unscrewing device, because installed surface is large, makes to install rear two interplanar static friction power comparatively greatly, makes this device reliably highly stable after mounting.Turning rolls front mud pan 6 six supporting rollerns 4 have been blocked, so the muddy water major part when constructing with drilling rod splash has been blocked in outside supporting rollern 4, diminished by muddy water effect when supporting rollern 4 rotates, thus because influence to sediment makes the degree of rolling wheel wear also will diminish.
