Description
Technical field
The utility model relates to machinery industry technical field, particularly a kind of large-scale steel structure crane girder brakes high-strength bolt punching device.
Background technology
Bolt as one of steel member connected mode connects, the features such as Yin Qi processing factory, material (bolt) standardization have been used widely, and easy in installation process, quick, be conducive to quality control and inspection, but because alignment error often causes repair welding reaming phenomenon, while running into metallurgical engineering large scaled crane beam by it, be difficult to join bore and process, even adopt in manufacturing process, join the member that bores processing, often because alignment error causes bolt, difficulty is installed, repair welding reaming phenomenon occurs often, affect project progress, increase again quality control difficulty simultaneously.
The conventional method for drilling of ANALYSIS FOR STEEL CRANE GIRDERS top flange plate and keep plate in metallurgical engineering:
1, after blanking by crane girder top flange plate and keep plate clamp, with radial drilling machine, join and drill hole: the preparation that needs are certain, to equipment and processing factory site, require high, can guarantee the machining accuracy of two hole in piece part, working (machining) efficiency is high, but while running into large scaled crane beam (more than beam length 45m, more than thickness of slab 50mm), operation easier strengthens.
2, in processing factory, adopt mould boring: this kind of mode is applicable to same kind of parts drilling in batch and large-scale component and should not adopts to join while boring and adopt, during boring, operation is relatively simple, drilling precision is high, but early stage, Mold Making required time and cost were high, and in successive projects, be subject to the differences such as bolt aperture, connecting portion, joint form, cause mould recycling rate of waterused not high.
3, the part drilling of ruling separately: this kind of mode is easy, but after processing, assembly precision is low, therefore should not adopt.
4, member is installed rear drilling: while making hanging beam and keep plate in making factory, all do not hole, after crane girder installs, carry out keep plate installation.Braking is analysed to plate and be laid on beam, by design size, keep plate is positioned to adjustment.At plan boring sites in curing, the decorative pattern on keep plate is polished, then at the braking lining out of having polished, indicate bolt hole position.With magnetic drill, keep plate and crane girder top flange are holed simultaneously.Whole round has bored that rear removing iron is cut, burr, carries out bolt installation.It is high that this kind joined drill method assembly precision, the problem that the bolt hole that can avoid alignment error to cause does not align.But operation inconvenience, longevity of service, efficiency are low.As adopt hollow boring bit drilling, and though can shorten drilling time, drill bit is fragile, cost is higher.
When the brakes that in above-mentioned 4 kinds of methods, the 1st, 2 two kinds of methods are carried out after crane girder is installed is installed, often occur that beam and keep plate bolt hole can not align phenomenon, hole fit on above, bolt is not just installed in hole below, cause bolt that difficulty is installed, affect installation quality and bolt strained performance, there is relatively large deviation, easily cause and do over again, reprocess, producing reason is mainly that processing factory's internal drilling time error causes, and the tired collection of member alignment error institute extremely, drilling again after need polishing keep plate repair welding, increase cost, affect again the duration; Although the 4th kind of method can solve above-mentioned quality problems, neither be very good, while running into large scaled crane beam, the cumulative thickness of crane girder top flange plate and keep plate can reach 60-120mm, and boring difficulty is long in time limit, cost is high, restricting tight rear operation construction, affecting track and crane gear and install.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, science is practical, large-scale steel structure crane girder brakes high-strength bolt punching device.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of large-scale steel structure crane girder brakes high-strength bolt punching device, comprise base, support and magnetic force rig, described support is provided with handwheel and the lifting platform being connected with handwheel, and magnetic force rig is fixed on lifting platform by stay-bolt, and frame bottom is arranged on base.
Described susceptor surface is provided with bolt orifice plate and support baffle plate, and base end face is provided with alignment pin, and the central axis of bolt orifice plate and alignment pin is on same straight line.
The diameter of described alignment pin is 16-30mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of large-scale steel structure crane girder brakes high-strength bolt punching device, have with low cost, simple in structure, process the feature easy, easy to use, science is practical, making base material therefor can utilize on-the-spot leftover pieces to make, magnetic force rig and support adopt stay-bolt to fix, do not damage rig, simultaneously can drilling on crane girder accurately, effectively reduce the deviation of crane girder hole and braking plate hole, there are wide market prospects.
