Abstract
The invention discloses a steel tube tower main material linking device. The steel tube tower main material linking device comprises an upper joint and a lower joint which are sleeved and fixed with each other, wherein at least one positioning key is arranged between the upper joint and the lower joint. According to the device, a steel tube tower main material linking way which is safe, reliable, convenient for construction and relatively low in cost is adopted, and components can be realized through simple mechanical processing.
Description
Technical field
The present invention relates to the main material coupling arrangement of a kind of steel tube tower in electric transmission line, is the one innovation to common flange bolt connection mode.
Background technique
At electric transmission line particularly in extra high voltage line, most of flange and the high-strength bolt of adopting of connection of the main material of steel tube tower connects, flange manufacturing cost is high, the fastening requirement of high strength king-bolt is compared with high pulling torque value, must just can complete by special electric instrument, and in high-lift operation, fastening very difficult; High-strength bolt not only cost high and application process in, more or less there are some problems.These problems, may cause because design bolt arrangement is unreasonable, stress nargin is too little, may be because raw material material is unstable, discreteness causes too greatly, also be likely heat treatment in course of working, rust cleaning, hot dip galvanizing process is unreasonable causes, or in unit in charge of construction's work progress, tighten that order, torsion control are unreasonable to be caused, due to these some uncertain factors, make the safety in production of steel tube tower in electric transmission line have certain hidden danger.
Summary of the invention
The object of this invention is to provide a kind of safe and reliable, easy construction, steel pipe that expense is lower
The main material connecting mode of tower, member used can be realized by simple and mechanical processing.
For achieving the above object, the present invention is by the following technical solutions:
The main material coupling arrangement of a kind of steel tube tower, it comprises upper connection, lower contact, upper connection and lower contact are fixed by socket, and at least one positioning key is set between described upper connection and lower contact.
Described fixing, in upper connection, between plane and lower contact lower plane, arrange to bear to overlap and fix.
Described lower contact and bear at least two positioning plate assemblies of inner room setting.
The described inward flange that bears cover lower end is screwed into the below of lower contact upper end outward flange from the gap portions of lower contact is inserted, and uses bolton from bearing the arc port of cover inserts positioning plate assembly location, transmits the suffered pulling force of main material.
The present invention includes upper connection, lower contact, positioning key, bear cover and positioning plate assembly.Wherein the bottom exterior circular column of upper connection is inserted in the inner cylinder of lower contact, adopts positioning key location, transmits horizontal force, and can be antitorque; The outer part of upper connection is that circle is positioned in lower contact, transmits main material pressure; The inward flange that bears cover lower end is screwed into the below of lower contact upper end outward flange from the gap portions of lower contact is put into, and inserts positioning plate assembly location fasteningly with a plain bolt from bearing the arc port of cover, transmits the suffered pulling force of main material.

Embodiment
As shown in Fig. 1-12, the main material coupling arrangement of a kind of steel tube tower, it comprises the upper connection 1 being connected with the main material 6 of epimere steel pipe, the lower contact 2 being connected with the main material 7 of hypomere steel pipe, and upper connection 1 is fixed by socket with lower contact 2, and between upper connection 1 and lower contact 2, at least one positioning key 3 is set.The quantity of positioning key 3 is set according to the actual requirements, can be one, can be also two, four etc., and the quantity of the present embodiment is taking two as example explanation.It should be noted that, between them, also can, for regular polygon prism coordinates, now not need to arrange positioning key 3; The outer cylindrical body length of upper connection 1 is less than 1 ~ 2 millimeter of the inner cylinder length of lower contact 2 in addition, thereby ensures that the outer part 11 of upper connection 1 is positioned in lower contact 2, transmits main material pressure.
Above-mentioned upper connection 1 and lower contact 2 are fixed by socket and refer to: in upper connection 1, between plane and lower contact 2 lower planes, arrange that to bear cover 4 fixing, lower contact 2 and bear at least two positioning plate assemblies of setting 5 between cover 4.The quantity of positioning plate assembly 5 is even number, is symmetrical arranged, and quantity can be two, can be also four, six etc.The quantity of the present embodiment is taking four as example explanation.
The described inward flange 8 that bears cover 4 lower ends is screwed into the below of lower contact 2 upper end outward flanges 9 from the gap portions 10 of lower contact 2 is inserted, and uses bolton from bearing the arc port of cover 4 inserts positioning plate assembly 5 location, transmits the suffered pulling force of main material.Gap portions and outward flange 9 cooperatively interact, and notch size is more bigger than outward flange 9, are convenient to assembling.The quantity of outward flange 9 and breach is consistent, can be four, also can be six.
