Abstract
The present invention relates to a power supply system, more specifically a technology for manufacturing slope varying bent pipes used for manufacturing steel towers of power transmission lines. According to a design scheme provided by the present invention, flanges are fixedly connected to a fixed and a movable angle holders respectively, one or two longitudinal end faces of steel pipes to be welded are cut into bevel faces according to a required slope angle, and then the longitudinal end faces of the steel pipe are welded together with corresponding flanges; the position of the movable angle holder is adjusted well later to cause the end faces of the free ends of two adjacent steel pipes to be aligned and tallied, and then the free ends of the two steel pipes are mutually welded together. By using the technology, the steel towers formed by connecting tubular pieces can be manufactured so as to greatly improve the strength of the steel towers, and the normal operation of the power transmission lines can be guaranteed.
Description
Technical field
The present invention relates to electric power system, the manufacturing technology of the change slope bend pipe that uses during specifically a kind of iron tower of power transmission line is made.
Background technology
In transmission line of electricity, cable generally is erected on the iron tower, because the span of cable is generally all bigger, is blowing or sleety weather, can bear very big cross force, thus to the requirement of iron tower than higher.Iron tower commonly used at present mainly is formed by connecting by section bars such as angle steel, but when the height of iron tower acquired a certain degree, this iron tower that utilizes section bar to be overlapped to form just was subjected to certain limitation.
Summary of the invention
The objective of the invention is to design a kind of iron tower of power transmission line with the production method and the equipment thereof that become sloping bend pipe, utilize this technology can produce the iron tower that is formed by connecting by tube-like piece, thereby improved the intensity of iron tower greatly, guaranteed the normal operation of transmission line of electricity.
According to design provided by the present invention, flange is fixedly connected on respectively on fixed angles seat and the movable corner seat, and one or two longitudinal terminal surface inclination angle on request of steel pipe to be welded cut into the inclined-plane, again the longitudinal terminal surface of steel pipe is welded together with corresponding flange, then, adjust the position of movable corner seat, the free end end face alignment of adjacent two steel pipes is coincide, the free end with two steel pipes is welded to each other together again.
Perhaps, one or two longitudinal terminal surface inclination angle on request of steel pipe to be welded is cut into the inclined-plane, again the longitudinal terminal surface of steel pipe is welded together with corresponding flange, flange is installed on fixed angles seat and the movable corner seat respectively then, adjust the position of movable corner seat again, the free end end face alignment of adjacent two steel pipes is coincide, and the free end with two steel pipes is welded to each other together again.
Before welding, placing the carriage that is used to support with positioning steel tube corresponding to the base of steel pipe free end.
The sloping bend pipe production equipment of a kind of change is characterized in that: install and fix angle seat and movable corner seat on base, the installation and the adjustment hole of several perforations is set respectively on the medial surface of fixed angles seat and movable corner seat.
Several are set on base is used to adjust and the fixing adjustment hole of the position of movable corner seat.On base, place and be used to support the also carriage of positioning steel tube.
The invention has the advantages that easy to operate, the positioning accuracy height, the interchangeability of the member that processes on this equipment is good, when constructing especially at the scene, owing to can exchange between each member, thereby is very easy to workmen's work.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is corner seat structure figure.
The specific embodiment
With flange 2,7 are fixedly connected on respectively on fixed angles seat 1 and the movable corner seat 8, and one or two longitudinal terminal surface inclination angle on request of steel pipe to be welded 4 cut into the inclined-plane, place the carriage 3 that is used to support with positioning steel tube 4 on corresponding to the base 5 of steel pipe 4 free ends, 6, make steel pipe 4 obtain good location and support, again the longitudinal terminal surface of two steel pipes 4 is welded together with corresponding flange 2 or 7 respectively, then, adjust the position of movable corner seat 8, the free end end face alignment of adjacent two steel pipes 4 is coincide, and the free end with two steel pipes 4 is welded to each other together again.When adjusting the position of movable corner seat 8, unclamp bolt earlier, after movable corner seat 8 is adjusted to the right place, tight a bolt again, movable corner seat 8 is fixed on the appointed positions.
Also can be earlier one or two longitudinal terminal surface inclination angle on request of steel pipe to be welded 4 be cut into the inclined-plane, again the longitudinal terminal surface of steel pipe 4 is welded together with corresponding flange, place the carriage 3,6 that is used to support with positioning steel tube 4 on corresponding to the base 5 of steel pipe 4 free ends, the flange that will have steel pipe 4 then is installed on respectively on fixed angles seat 1 and the movable corner seat 8, adjust the position of movable corner seat 8 again, the free end end face alignment of adjacent two steel pipes 4 is coincide, and the free end with two steel pipes 4 is welded to each other together again.
Above-mentioned two kinds of methods all are feasible in practical operation.
In described production equipment, install and fix angle seat 1 and movable corner seat 8 on the base 5, the installation and the adjustment hole 9 of several perforations are set respectively on the medial surface of fixed angles seat 1 and movable corner seat 8, so that adjust the position of the upper and lower, left and right of flange 2,7 on the seat of angle, guarantee to become the crudy of sloping bend pipe.
Several are set on base 5 are used to adjust and the fixing adjustment hole 10 of the position of movable corner seat 8, to adjust two angles of waiting to connect 4 of steel pipes.
By adjusting position and movable corner seat 8 the position on base 5 of flange 2,7 on fixed angles seat 1 and movable corner seat 8, can guarantee to become the machining accuracy of sloping bend pipe effectively.
Placement is used to support the also carriage 3,6 of positioning steel tube 4 on base 5, so that welding.
