Detailed description of the invention
Embodiment 1: a kind of thruster of jumbo tensioned lines and using method, see Fig. 1-4, the present invention includes tensioned lines 14, front wheel 23, rear wheel 20, the rig planker 19 of jumbo and the forward beam 22 of jumbo, described rig planker 19 is slidably mounted on the slideway of thruster of jumbo, described front wheel 23 and rear wheel 20 are separately fixed at the cylinder barrel front and back end of propelling cylinder 21 in propeller, described tensioned lines 14 is two, be respectively pull rope and return rope, wherein pull rope one end is fixed on rig planker 19, its other end pile warp front wheel 23 is fixed on the forward beam 22 of jumbo, described return rope one end is fixed on rig planker 19, its other end pile warp rear wheel 20 is fixed on the forward beam 22 of jumbo, tensioned lines 14 one end is provided with hanging ring 12, this tensioned lines 14 is fixedly connected on described rig planker 19 other end via hanging ring 12 and is provided with governing mechanism of tension, tensioned lines 14 is connected with forward beam 22 by governing mechanism of tension.
Governing mechanism of tension comprises screw thread 15, adjusting nut 16 and adjusting screw(rod) 17, and tensioned lines 14 is fixedly connected with forward beam 22 by screw thread 15, adjusting screw(rod) 17 successively, and described adjusting screw(rod) 17 is arranged on forward beam 22, and it is installed with adjusting nut 16.
Hanging ring 12 in the present invention by tensioned lines 14 around forming, and by tensioned lines 14 arrange compression iron hoop 13 shape.The endoporus compressing iron hoop 13 is gradually-reducing shape, and aperture little Chu is positioned at hanging ring 12 end far away.The top of front wheel 23 and/or rear wheel 20 is fixedly installed dust cover.Bearing on the wheel shaft of front wheel 23 and/or rear wheel 20 is the radial ball bearing with sealing ring.The below of hanging ring 12 on rig planker 19, is provided with the sector grooves corresponding with hanging ring 12 position.Front wheel 23 and/or rear wheel 20 are the pulley of nylon material.
In the present invention, the using method of tensioned lines is that tensioned lines 14 one end is fixedly connected with screw thread 15, this screw thread 15 and the adjusting screw(rod) 17 be arranged on forward beam 22 fasten to be connected by threaded engagement and connect, by the rotation of adjusting nut 16 set firmly outside adjusting screw(rod) 17, drive the rotation of adjusting screw(rod) 17, and then the tensile force of the position of screw thread 15 and tensioned lines 14, this tensioned lines 14 other end is fixed on rig planker by hanging ring 12.
In the present invention, the tensile force of tensioned lines 14 is not more than 25KN.
When constructing, when brill executed by rig, rig is at forward beam 22, stretch out piston rod by rig propelling cylinder and promote front wheel 23, front wheel 23 drives traction tensioned lines to rotate, traction tensioned lines is when rig propelling cylinder piston rod stretches out, traction rig displacement, thus drive rig walking, completes rig and executes feed motion in drill-through journey at jewel hole.When propelling cylinder piston rod is retracted, tensioned lines 14 hauls rig and gets back to starting point.
In the present invention, adjusting screw(rod) 17 one end is arranged on forward beam 22, and one end is thread, controls tensioned lines degree of tightness by adjusting nut 16, and thread connects tensioned lines connector.Screw thread 15 one end is endoporus without screw thread, and connect tensioned lines use, the other end is the internal thread hole having screw thread, connects the connecting filament end of thread of adjusting screw(rod) 17.
Hanging ring is the iron hoop of an endoporus Φ 24mm, and during making, tensioned lines, around one circle, puts two tensioned lines 14 with compression iron hoop 13, compressed with tube press machine, just passable.By in tensioned lines 14 patchhole that customized in the without screw thread endoporus of screw thread 15 one end, compressed with tube press machine; The other end docks with adjusting screw(rod) 17 thread 15 end processed, and tightens.
The endoporus compressing iron hoop 13 in the present invention is gradually-reducing shape, and aperture little Chu is positioned at hanging ring 12 end far away.Be the self-locking of conveniently tensioned lines, make tensioned lines at work can not slippage, more stable.
In order to further reduce wearing and tearing, part be have also been made to supporting pulley and improve, such as because work-yard dust is large, above pulley, be fixedly installed dust cover.Select bearing to be radial ball bearing with sealing ring simultaneously, while self-lubricating facilitates pulley rotation, avoid tensioned lines 14 and the slip of pulley room, reduce wearing and tearing.The below of hanging ring 12 on rig planker 19, is provided with the sector grooves corresponding with hanging ring 12 position.To facilitate the rotation of hanging ring in motion process, reduce the wearing and tearing that corner angle bring, select the pulley of nylon material wear-resisting to increase simultaneously.
Hydraulic drill ring traction tensioned lines structure design of the present invention, comprise the redesign of traction tensioned lines front end screw rod, cancel the structure that screw rod is fixed to rig, be designed to hanging ring, hanging ring is suspended on rig, whole hanging ring structure length is 10mm, substantially can not proceed in front wheel 23, thus available protecting tensioned lines 14; Rear end adjusting screw(rod) 17 is designed to adjusting screw(rod) 17 and is connected with the form of screw thread 15 with tensioned lines 14, adjusting screw(rod) 17 is to be fixed in tensioned lines 14 by screw thread 15, only tensioned lines, adjusting screw(rod) 17 need be pulled down when adjusting screw(rod) 17 damages and change new adjustment screw mandrel, and not need to change whole tensioned lines.
Embodiment 2: the operating principle of the present embodiment is with embodiment 1, concrete difference is, described governing mechanism of tension comprises screw thread 15, adjusting rope 24, adjustment screw 26, backing plate 27 and U-shaped stationary pipes 25, screw thread 15 two ends are fastenedly connected adjusting rope 24 and tensioned lines 14 respectively, curved end and the adjusting rope 24 of described U-shaped stationary pipes 25 are fixed, its openend is fixed in backing plate 27, penetrate backing plate 27 by adjustment screw 26 and forward beam 22 is fixed on forward beam 22, the length of this adjustment screw 26 shaft is not less than plate thickness and screw length sum.
During work, adjusting rope 24 one end is fixed by screw thread and tensioned lines, after the other end and U-shaped stationary pipes 25 are fastened, by the position of adjustment screw 26 on deep forward beam 22, regulate the position of U-shaped stationary pipes 25, and then regulate the tensile force of tensioned lines 24, wear and tear only change adjusting rope if reach adjusting rope 24 equally, reduce the object of wearing and tearing from entirety.When this embodiment starts fixing most, between backing plate and forward beam, there is distance, by later stage adjustment distance adjustment tensile force.
Structure of the present invention is simple, and easily operate, it is very convenient to disassemble and install, the repeated multiple times use of tensioned lines energy, safe and reliable, time saving and energy saving, greatly improves the efficiency of work, also enhances overall abrasion resistance and application life simultaneously to the improvement of related accessory.
Each concrete parameters of structural dimension in change above-described embodiment and the equivalent of component substitute, and can form multiple specific embodiment, be common excursion of the present utility model, do not repeat them here.
