Description

A kind of hole machined mechanism
Technical field
The present invention relates to cable steel tower making apparatus technical field in electrical network, particularly relate to a kind of hole machined mechanism.
Background technology
Iron tower of power transmission line is called for short electric power tower, is generally divided in shape: wine glass-shaped, cathead, upper font, dry font and barrel shape five kinds.Divide by purposes and have: anchor support, tangent tower, angle tower, transposition tower (restringing phase position tower), terminal tower and crossover tower etc..They be structurally characterized in that various tower all belongs to space truss structure, rod member is mainly made up of single equal leg angle or combination angle steel, material generally uses Q235(A3F) and Q345(16Mn) two kinds, rough bolt it is connected by between rod member, by bolt by Shear connection, whole tower is made up of angle steel, junction steel plate and bolt, and individual part such as column foot etc. is welded into a molectron by several block plates, therefore galvanizing anticorrosion, erection extremely convenient of transporting and construct.
Angle steel is the important component part of existing iron tower of power transmission line, and in view of welding heat affected, the form that much the most with bolts annexation between angle steel and angle steel is.In prior art, bolt hole on angle steel typically uses the mode of prefabrication, but when mounted, appoint and may have fraction angle steel because of dimensional discrepancy or the reason of leakage boring, need scene boring, for relatively thin angle steel in prior art, can manually prepare by perforating press, for thicker angle steel, typically can be drilled by instrument scenes such as power drills.But, the bolt hole drilled by power drill scene, generally there are the problem that positional precision is low.
Summary of the invention
For in above-mentioned prior art for relatively thin angle steel, manually can prepare by perforating press, for thicker angle steel, typically can be drilled by instrument scenes such as power drills.But, the bolt hole drilled by power drill scene, generally there are the problem that positional precision is low, the invention provides a kind of hole machined mechanism.
A kind of hole machined mechanism that the present invention provides solves problem by techniques below main points: a kind of hole machined mechanism, including angle steel fixing device and power drill guider, described angle steel fixing device includes base plate, ambulatory splint, strap and clamping section, described ambulatory splint is parallel to each other with strap, strap is perpendicularly fixed on base plate, and described clamping section is for adjusting the spacing between ambulatory splint and strap;
Described power drill guider includes that wing plate, fixture block and guide post, described wing plate are fixed on strap away from the side of ambulatory splint, and the length direction of wing plate is parallel with the length direction of strap, and the upper surface of wing plate is parallel to each other with the upper surface of base plate;
Described fixture block is channel-section steel shape, and the free side of described wing plate is arranged in the bayonet socket of fixture block, also includes the fastening bolt being threadedly connected on fixture block, and described fastening bolt is used for making to produce compressive stress between fixture block and wing plate to realize fixture block fixing on wing plate;
Described guide post is fixed on fixture block, and guide post is vertical with base plate, described guide post is also arranged with the sliding sleeve that can slide along guide post length direction, described sliding sleeve is additionally provided with installing plate.
Concrete, above strap and ambulatory splint are for the clamping any to angle steel to be processed: under the clamping part driving to ambulatory splint, ambulatory splint is drawn close to strap side, can realize firm being fixed on this processing unit (plant) of angle steel to be processed.In the case of fastening bolt is relaxed, fixture block can slide, so along the length direction of wing plate and width on wing plate, after fixing for angle steel to be processed, guide post moves along with fixture block, can be relative to angle steel to be processed, in the length and width direction motion that angle steel to be processed is processed.Plate installed above is used for fixing power drill, as fixed a base being provided with screwed hole on existing power drill or arranging link bolt hole on the housing of power drill, by power drill bolt is connected on installing plate, realize power drill to be connected with this structural rigidity, so, can make power drill in the course of the work, its length direction being only capable of along guide post moves, and can reach and retrains the purpose of bore position on angle steel to be processed.The simple in construction of above structure, it is easy to be carried to steel tower erecting bed, the position constraint to angle steel is completed by angle steel fixing device, power drill drill bit bore position point on angle steel is kept by power drill guider, this kind of mode is used to complete the on-the-spot boring of steel tower corner iron, not only there is the advantage that bore position precision is high, the advantage also with human users's safety of beneficially holing.
Above fastening bolt is used for making to produce compressive stress between fixture block and wing plate to realize the fixture block fixing form on wing plate, its concrete mode is after the end of fastening bolt contacts with the upper surface of wing plate or lower surface, by rotating fastening bolt further, fastening bolt length between fixture block and wing plate gradually becomes, so, normal pressure between wing plate and fixture block can produce enough maximum static friction forces, it is achieved wing plate is fixing with fixture block.
Further technical scheme is:
Described wing plate and strap are the different edge that overall structure, wing plate and strap are respectively an angle steel.In above structure, wing plate upper surface is mutually perpendicular to strap clamping face, so, uses current material, can well keep fixture block in the conversion process of position, and guide post axis is relative to processed angle steel limit mutually orthogonal relationship.
Form is implemented as clamping section, described clamping section includes threaded rod, threaded block and turning handle, the axis direction of described threaded rod is positioned at the spacing direction of ambulatory splint and strap, threaded block is fixed on base plate, threaded rod is threadeded with threaded block, and ambulatory splint is between strap and clamping section, described turning handle is fixedly connected on threaded rod.In above structure, by rotating threaded rod, change the position relative to strap, the end of threaded rod, reach to drive the ambulatory splint purpose to strap one lateral movement.Above turning handle applies the force application part of torque as operator on threaded rod.
Can be along with the forward or reverse of threaded rod as a kind of ambulatory splint, move away from strap or near strap, simultaneously, length direction along processed angle steel, ambulatory splint and strap all can be good at retraining processed angle steel, to reduce or to avoid in boring procedure, processed angle steel because self vibration influence boring smoothness and the technical scheme of gained hole precision, described threaded rod is near the side ball-joint of one end of ambulatory splint Yu ambulatory splint, described clamping section is multiple, and multiple clamping section is distributed along the length direction of ambulatory splint.
Owing to the earth's surface, setting area of steel tower mostly is earth, for ease of base plate is fixed on earth's surface, it is beneficial to keep angle steel position during processed, to facilitate operator to hole, the bottom surface of described base plate is further fixed on the many earth anchors vertical with base plate.
The method have the advantages that
This architecture is simple, it is easy to be carried to steel tower erecting bed, the position constraint to angle steel is completed by angle steel fixing device, power drill drill bit bore position point on angle steel is kept by power drill guider, this kind of mode is used to complete the on-the-spot boring of steel tower corner iron, not only there is the advantage that bore position precision is high, the advantage also with human users's safety of beneficially holing.
