Description
Technical field
The utility model belongs to the electric power overhaul field of the electric power pylon in electric system, particularly relates to a kind of guide rail stepping on tower for electric power overhaul.
Background technology
Current guide rail bracket adopts pipe mostly, and section bar adopts angle steel mostly.Such one side, angle steel needs before connecting with pipe angle steel to be processed suitable fillet to ensure that it fully contacts with pipe, and the bad control of oad Mismachining tolerance of fillet; On the other hand, pipe is connected by welding manner with angle steel, and weld is many, welding capacity is large, even expertly welder's welding also can produce distortion, and the guide rail bracket distortion after welding is difficult to correct, the straightness accuracy of guide rail requires also just to be difficult to ensure, and then can affect the running precision of equipment; The third aspect, because the welding technique level of welder itself is uneven, welding quality is difficult to all reach higher degree, and slag inclusion, pore, crackle, undercut, any one weld defect such as lack of penetration all can affect the bulk strength of guide rail bracket; Fourth aspect, guide rail bracket is spliced by the standard knot of a section certain length, and standard knot machines the zinc-plated process of rear overall thermal, particularly has the place of weld seam, is easy to produce list edge, and zinc-plated appearance is very poor.
Utility model content
The purpose of this utility model is to provide the guide rail stepping on tower for electric power overhaul that a kind of structure is simple, easy to make, precision is higher.
For achieving the above object, the technical solution adopted in the utility model is, a kind of guide rail stepping on tower for electric power overhaul, this guide rail is fixedly spliced by standard knot, described standard knot comprises guide frame, bracing frame and tooth bar, guide frame, bracing frame lay respectively at the both sides of standard knot, support frame as described above is included on same structure face and arranges and be parallel to each other two support tubes, and described guide frame corresponds to support frame as described above and is included on same structure face and arranges and be parallel to each other two guide pipes; Described support tube is formed by connecting by the mode of rectangular steel pipe by expand tube, and guide pipe is formed by connecting by the mode of rectangular steel pipe by expand tube; Be fixedly connected with between two support tubes between the first connection shaped steel, two guide pipes and be fixedly connected with the second connection shaped steel, be provided with the 3rd between the first adjacent connection shaped steel, the second connection shaped steel and connect shaped steel, the first connection shaped steel and the 3rd connects between shaped steel, be all fixedly connected with by attaching parts between the second connection shaped steel and the 3rd connection shaped steel; Connected by bolt between described second connection shaped steel and tooth bar.
When two standard knots splice, between two guide frames, between two bracing frames, use Stud connection respectively, pass through tooth bar connecting plate rivet between two tooth bars together.
Described rectangular steel pipe is hot galvanized steel pipe.
The beneficial effect that the utility model produces is, guide pipe in the utility model, support tube are rectangular steel pipe, connection between guide pipe, support tube all adopts rectangular steel pipe to be connected by the mode of expand tube, solve angle steel be in the past connected with pipe produce when being welded to connect slag inclusion, pore, crackle, undercut, the problem such as lack of penetration, effectively improve the bulk strength of guide rail bracket; Adopt the independent pot galvanize process of parts, then assembled, zinc-plated presentation quality is greatly improved, and guide rail antiseptic power is significantly improved simultaneously; And guide rail does not exist welding operation in manufacturing process, so effectively control the harm that the metal fumes, noxious gas, arc light radiation, electromagnetic field of high frequency and noise etc. that produce in welding process cause work human and environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 Plays joint;
Fig. 2 is the structural representation of guide pipe in embodiment 1, support tube junction;
Fig. 3 is the structural representation of stitching portion between embodiment 1 Plays joint.
As Figure 1-3, a kind of guide rail stepping on tower for electric power overhaul, this guide rail is fixedly spliced by standard knot 4, described standard knot 4 comprises guide frame 5, bracing frame 6 and tooth bar 1, guide frame 5, bracing frame 6 lay respectively at the both sides of standard knot 4, support frame as described above 6 is included on same structure face and arranges and be parallel to each other two support tubes 8, and described guide frame 5 corresponds to support frame as described above 6 and is included on same structure face and arranges and be parallel to each other two guide pipes 9; Described support tube 8 is formed by connecting by the mode of rectangular steel pipe by expand tube, and guide pipe 9 is formed by connecting by the mode of expand tube by rectangular steel pipe (size of the rectangular steel pipe used with being connected support tube 8 is different); Be fixedly connected with between two support tubes 8 between first connection shaped steel, 11, two guide pipes 9 and be fixedly connected with the second connection shaped steel 12, be provided with between the 3rd connection shaped steel 13, first connection shaped steel 11 and the 3rd connection shaped steel 13, between the second connection shaped steel 12 and the 3rd connection shaped steel 13 between the first adjacent connection shaped steel 11, second connection shaped steel 12 and be all fixedly connected with by attaching parts 14; Connected by bolt between described second connection shaped steel 12 and tooth bar 1.
When two standard knots 4 splice, connect with bolt respectively between two guide frames 5, between two bracing frames 6, be riveted together by tooth bar connecting plate 2 rivet 3 between two tooth bars 1.
Rectangular steel pipe used is hot galvanized steel pipe.
