Description

Steel tower corner iron angle of release frock clamp
Technical field
The present invention relates to a kind of angle of release frock clamps, and in particular to steel tower corner iron angle of release frock clamp.
Background technique
Steel tower is a kind of freestanding steel structure set up to realize a certain aerial load of receiving or communication function.It is existing Steel tower be generally used angle steel, steel sheet component is manufactured, be connected with and be composed, only part use a small amount of welding Part (such as hanging wire angle steel stiffening plate), basic seat board is generally used electric welding.Tower upper-part is generally used galvanizing by dipping Anti-corrosion.
Angle steel is commonly called as angle bar, is that both sides are orthogonal at angular strip steel.Have equal leg angle and unequal angle it Point.Two hem widths of equal leg angle are equal.Its specification is indicated with hem width × hem width × side thickness millimeter.Such as ∠ 30 × 30 × 3, Indicate that hem width is the equal leg angle of 30 millimeters, 3 millimeters of Bian Houwei.Also available model indicates that model is the bentimeters of hem width, such as ∠3#.Model does not indicate the size of different sides thickness in same model, thus by the hem width of angle steel, side thickness ruler on the documents such as contract It is very little to fill in complete, it avoids individually being indicated with model.Angle steel can need to form a variety of different primary structure members by the difference of structure, It can make the connector between component.It is widely used for various building structure and engineering structure, such as house beam, bridge, power transmission tower, lifting Transport Machinery, ship, industrial furnace, reaction tower, receptacle stand and warehouse.
The surface quality of angle steel has regulation in a standard, and general requirement must not deposit harmful defect in use, such as layering, It scabs, crack, scratch and corrosion etc..
Angle steel, in order to make the specific position on angle steel matching steel tower between corresponding component, needs diagonal steel in actual installation Angle of release is carried out, i.e., the interior angle of angle steel is reached into the angle greater than 90 °, and the interior angle after angle of release is made to match its required installation site.
In existing steel angle opening technique, angle steel is placed on the lower die that section is triangle, is then pressed in starting Mould makes angle steel under the action of upper die, and two limb sides are mobile respectively along the two sidewalls of lower die, until completing opening for angle steel Angle.During entire angle of release, one end on angle steel inner wall far from interior angle is contacted with lower die side wall, and with upper die Pressing action slides on lower die, and sliding can not only wear the inner wall of angle steel, and solid when having on lower die or angle steel inner wall When body particle, the inner wall of angle steel during angle of release, can also be made to generate scratch.And if surface abrasion even generates the angle steel of scratch Without filling up or grinding process, it is uneven to not only result in spray painting, influences its rust-proof effect, can also destroy angle steel and steel plate Fitness between part.
Summary of the invention
It is an object of that present invention to provide steel tower corner iron angle of release frock clamps, solve in steel angle opening, on angle steel inner wall One end far from interior angle, which can be worn to be arranged, leads to the problem of scratch.
The present invention is achieved through the following technical solutions:
Steel tower corner iron angle of release frock clamp, including locating piece, the locating piece is isosceles triangular prism, where its stringcourse Side wall on be provided with several guide grooves, the axis of the guide groove and this axis between the orthographic projection line on bottom surface Angle is equal to the side wall where stringcourse and the angle between bottom surface;It is provided with guide pad in each guide groove, in guide pad Upper one end far from guide groove slot bottom is hingedly provided with clamp assemblies, and hinge axes are parallel to the side wall where corresponding stringcourse. Clamp assemblies be the component with clamping function, such as spring clip, jumper folder, crocodile clip or pass through fixed block and movable block To realize clamping function, then electromagnet, sucker.
The angle between side wall on locating piece where stringcourse is matched with the size at the angle being unfolded needed for angle steel.It will be to angle of release Angle steel be placed on locating piece, and on the side wall where making two limb sides of angle steel be each positioned at a stringcourse respectively, and pass through folder Component is held to clamp one end on two limb side of angle steel far from interior angle;Then start lower die, be embossed in pushing and be located at positioning On angle steel on block, so that two limb sides of angle steel move down, and the interior angle of angle steel is gradually expanded, until on two limb side of angle steel Inner wall is respectively contacted with the side wall where stringcourse on locating piece and parallel respectively;During steel angle opening, two limb sides of angle steel to When lower mobile, opposite sliding between guide pad and guide groove, and friction is generated, and the clamped component clamping in two limb sides of angle steel Firmly, the limb side of angle steel is not by frictional force, therefore one end on angle steel inner wall far from interior angle will not be worn, and will not produce Raw scratch, without the later period polishing or fill up, improve work efficiency, reduce number of rewelding.
Further, the clamp assemblies include fixed block and bolt, and one end of fixed block is provided with through slot, described logical The axis of slot is parallel to the side wall where corresponding stringcourse, and the other end and guide pad of fixed block are hinged, the bar portion end of the bolt End is located in through slot after remotely located piece on through slot of cell wall, and bolt is threadedly coupled with this cell wall.
Further, one end on the guide pad far from guide groove slot bottom is provided with trunnion I, separate in fixed block One end of through slot is provided with trunnion II, one end and the one of fixed block separate on trunnion II far from guide pad on the trunnion I End is hinged.
Further, the one end being located on the bolt in through slot is disposed with installation axle and rubber sheet gasket, described Installation axle and bolt coaxial line, and installation axle and bolt are rotatablely connected, rotating bolt, installation axle can not rotate.
The limb side of angle steel is located in through slot, and is bolted.The setting of rubber sheet gasket is to protect on angle steel It with the position of threaded bolt contacts, avoids the screwing force of bolt excessive, angle steel surface is caused to generate dent.
Further, the guide pad is spherical shape, and in the cross section of the guide groove, slot bottom is major arc shape, and slot bottom Cross-sectional diameter it is consistent with the sphere diameter of guide pad.Guide pad is arranged to spherical shape, improves the mobile stationarity of guide pad.
Further, a guide groove, and the guide groove on each side wall are provided on the side wall where each stringcourse It is uniformly distributed along the axis of locating piece.
Compared with prior art, the present invention having the following advantages and benefits:
1, steel tower corner iron angle of release frock clamp of the present invention, during steel angle opening, two limb sides of angle steel are moved down When, opposite sliding between guide pad and guide groove, and friction is generated, and the clamped component in two limb sides of angle steel clamps, angle The limb side of steel is not by frictional force, therefore one end on angle steel inner wall far from interior angle will not be worn, and will not generate and draw Trace, without the later period polishing or fill up, improve work efficiency, reduce number of rewelding;
2, steel tower corner iron angle of release frock clamp of the present invention, the setting of rubber sheet gasket are connect on angle steel with bolt to protect The position of touching avoids the screwing force of bolt excessive, and angle steel surface is caused to generate dent;
3, steel tower corner iron angle of release frock clamp of the present invention, is arranged to spherical shape for guide pad, improves guide pad movement Stationarity.
