Description
Technical field
The present invention relates to cable steel tower attachment technique field in electrical network, particularly relate to a kind of electric power tower foot and prop up structure.
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.For exhaling the high steel tower at below 60m, a wherein main material of steel tower arranges foot nail, steps on tower operation with convenient construction operating personnel.
Authorization Notice No. is CN 203879089
The patent of invention of U discloses one and steps on column foot pin structure, this foot pin structure is fixed on steel tower by the bolt hole being arranged on a main material of steel tower, it is different from conventional steel cat ladder, it is not only simple in structure, material cost is few simultaneously, installation process need not welding, is beneficial to keep steel tower service life, low cost.But more than step on column foot to follow closely in use, it is big that construction operation personnel are climbed security implication by the reliability of securing member fastening: when fastener coming loose, foot nail rotates around its section of trampling, the foot nail that guardrail fragment position changes can not provide protection for the foot of operator, rotate changes the stress point of operator foot, and both the above situation all can increase the operating risk of climbing personnel.
Summary of the invention
For employed in above-mentioned prior art to foot to follow closely the reliability dependency that the safety of in use operator fastened by securing member big, and the fastening situation of securing member its use during it may happen that change, so, just it is unfavorable for that operator climb the problem of safety, the invention provides a kind of electric power tower foot and prop up structure.
A kind of electric power tower foot that the present invention provides props up structure and solves problem by techniques below main points: a kind of electric power tower foot props up structure, body is followed closely including foot, described foot nail body includes the section of trampling, one end of the described section of trampling is provided with external thread section, also include two the first lock nuts threadeded with described external thread section, also include the secondary bar of at least a piece parallel with described external thread section, described secondary bar is connected by linkage section and the section of trampling are fixing, and it being provided with external screw thread on pair bar, threaded on described external screw thread have two the second lock nuts.
Concrete, in above scheme, prop up for each steel tower foot, the main material of steel tower drills quantity be secondary bar quantity with trample the through hole of hop count amount sum after, secondary bar and the section of trampling insert different through holes respectively, the clamping to main material by the first lock nut and the second lock nut, it is achieved steel tower foot props up the connection on steel tower.
In this structure, owing to steel tower foot props up and steel tower at least two junction points, so, operating personnel trample this steel tower foot prop up time, under the torque that steel tower foot is propped up by operating personnel foot, owing to through-hole side is in the face of secondary bar side face, through-hole side is in the face of the constraint of the section of trampling side, the section of trampling can not rotate around the axis of self, so, follow closely compared to existing steel tower foot, either because original fastener pretightning force is inadequate, or screw thread in use becomes plastic deformation due to elastic deformation, also it is because under wind load, in the case of steel tower foot props up securing member absent-mindedness, the stress point of operating personnel foot will not change, operating personnel is conducive to keep its position of centre of gravity of standing, it is beneficial to the safety that operating personnel stands and climbs.
Above first lock nut and the section of trampling, the second lock nut and the type of attachment of secondary bar, it is easy to according to concrete operation environment and uses the installation having needed it on steel tower, the most also having and be conveniently adjusted this steel tower foot and prop up the technique effect of the extension elongation relative to steel tower.
Further technical scheme is:
For avoiding operating personnel foot to be slipped away the safety that this structure, beneficially operating personnel stand and climb by the free end of foot nail body, described in the section of trampling the other end on also set up guardrail section, described guardrail section is connected with the section of trampling by one end bending section.In above structure, the guardrail section that this steel tower foot after preferably installing props up upwarps relative to the section of trampling, and so, can be limited between the main material of steel tower and guardrail section by the foot position of operating personnel.
It is provided with two spring pads between a kind of loosing Prevention Technology scheme propped up as this steel tower foot, two the first lock nuts and two the second lock nuts.
Effectively trampling the technical scheme of length as a kind of reduction in the linkage section impact section of trampling, described linkage section is flat rod, secondary bar and trample Duan Junyu flat rod and be welded to connect, and the thickness direction of flat rod is positioned at the length direction of the section of trampling.
Can not only keep the well section of trampling anti-rotation performance, simultaneously simple in construction as one, it is simple to processing and manufacturing and the technical scheme of connection, the quantity of described secondary bar is one.
The method have the advantages that
In this structure, owing to steel tower foot props up and steel tower at least two junction points, so, operating personnel trample this steel tower foot prop up time, under the torque that steel tower foot is propped up by operating personnel foot, owing to through-hole side is in the face of secondary bar side face, through-hole side is in the face of the constraint of the section of trampling side, the section of trampling can not rotate around the axis of self, so, follow closely compared to existing steel tower foot, either because original fastener pretightning force is inadequate, or screw thread in use becomes plastic deformation due to elastic deformation, also it is because under wind load, in the case of steel tower foot props up securing member absent-mindedness, the stress point of operating personnel foot will not change, operating personnel is conducive to keep its position of centre of gravity of standing, it is beneficial to the safety that operating personnel stands and climbs.
Above first lock nut and the section of trampling, the second lock nut and the type of attachment of secondary bar, it is easy to according to concrete operation environment and uses the installation having needed it on steel tower, the most also having and be conveniently adjusted this steel tower foot and prop up the technique effect of the extension elongation relative to steel tower.
