It combines together, has the characteristics that good integrity, high reliablity, load transmission efficiency can be effectively improved, glue section is avoided to destroy, and protected
The structural integrity and insulating properties of whole section of tower body are demonstrate,proved.
Three, standardized double-pipe metal flange and connector is arranged in the top, bottom both ends of insulation truss module in the present invention, into
One step facilitates any combination and connection between module and module, between module and metal tower body.
Detailed description of the invention
Fig. 1 is the overall schematic of the specific embodiment of the invention；
Fig. 2 is the side schematic view of the specific embodiment of the invention；
Fig. 3 is the front schematic view of the specific embodiment of the invention；
Fig. 4 is specific embodiment of the invention spherical shape hanging point schematic diagram.
As shown in the figure: figure 2, lower live line work insulating section 3, bump joint 4, ball are worn in upper live line work insulating section 1, insulation
Shape hanging point 5, insulating ladder 6, diamond shape tower window 7.
Specific embodiment
As shown in Figure 1, the present embodiment is an insulation truss module convenient for combination and installation, generally one rectangular
Shape insulation truss is made, by thoroughly doing away with more for using in the insulation truss module of transmission tower using GFRP composite material
Edge bar combines to be formed by insulating joint, is equipped with standardization bushing type bump joint 4 on the top of module and bottom end in order to reality
Existing modular assembling uses.To be set along side wall on front side of insulation truss module convenient for line electricity operation and line outage maintenance
There is dedicated dismountable insulating ladder 6, insulating ladder 6 is removably attached on insulation truss module, to replace at any time,
Avoid because insulating ladder 6 aging due to cause climbing unexpected.Insulating ladder 6 is affixed side with insulation truss module and is equipped with perpendicular to exhausted
Edge ladder 6 or the inserted link tilted down, insulation truss module is equipped with the jack being used in combination with inserted link, for convenient for operator
Member's climbing insulating ladder 6, jack protrude from insulation truss module surface, so that depositing between insulating ladder 6 and insulation truss module
In certain interval to hold.Above and below insulating ladder 6 great convenience personnel, while avoiding insulation truss module and being ground by climbing
The electric property of insulation truss module is effectively ensured in damage.
The width of insulation truss module is 2200mm, above it, is respectively arranged below with two layers of insulating bar being laterally arranged
Module is integrally divided into upper live line work insulating section 1 by frame, figure 2, lower live line work insulating section 3 are worn in insulation.Upper livewire work
Insulating segment 1, lower charged insulating section height are identical, are 2000mm, it is 9000mm that 2 height of figure is worn in insulation.In the present embodiment, module
Length, height, width data can uniformly be laid down a criterion according to Practical Project, produce in enormous quantities in order to factory and
Processing, can greatly reduce the production time and reduce production cost.
Four sides of upper live line work insulating section 1 and lower live line work insulating section 3 are equipped with transposition insulator bar to increase
The top and bottom of intensity, upper live line work insulating section 1 are equipped with same size, the corresponding diamond shape port in position, diamond shape port
It is electric power personnel in wearing on truss module of insulating that effect, which is while reinforcing the structural stability of upper live line work insulating section 1,
Shuttle movement provides activity space.When operator climbs up live line work insulating section 1 and lower live line work insulating section 3, due to exhausted
Edge truss module integral insulation, therefore when operator wears screening clothing and guarantees that it is not contacted with grounding body, it can will grasp
It is considered as equipotential live line work as personnel, livewire work can be carried out by upper tower safely.It is twined between insulating joint and insulating bar using no metal
Around aggregators technology, by shell package, pre-soaking fiber wrapping around, mould pressurizing solidify three steps processing make insulating bar with
Insulating joint combines together, to form the insulation truss module for being not necessarily to secondary assembly.
In conjunction with shown in Fig. 2, Fig. 3, four sides in front side, rear side, left side, right side that figure 2 is worn in insulation are all made of diamond shape tower
Window 7 designs, and on rear side of front and back, the left and right sides it is symmetrical two-by-two, the top of diamond shape tower window 7 and front side side top in front and rear sides
Joint is equipped with using solid spherical hanging point 5 made of GFRP composite material, and as shown in connection with fig. 4, the insulating bar is embedded at ball
Internal portion, the obliquely downward rearward of the spherical hanging point 5 of front side, rear side the forward obliquely downward of spherical hanging point 5 be equipped with and worn to insulation
The hanging hole of the intermediate side of figure 2 inclination protrusion.By two of correspondence spherical hanging points 5, can by setting V-type string hanging point or
I type string hanging point is to adapt to different adaptation environment.
Rod piece is hollow circular-tube form in the present embodiment, and using traditional pultrude process, connector is then using winding and mould by hand
The molding of the connector of rod piece and the assembly of truss structure are handled and are completed simultaneously, ensure that whole section of tower body by pressure technique
Structural integrity and insulating properties.
In conclusion insulation truss module structure provided by the present invention is simple but has good electric insulating quality, steady
It is qualitative, and its standard modular design applicable situation extensively, convenient for producing in batches and being applied in combination, transmission tower can be shortened
Construction time and cost improve transmission tower and set up efficiency.
