Improved auxiliary pole firm banking
Technical field
The present invention relates to power construction and use construction equipment, particularly relate to the fixed mechanism of transmission line of electricity group tower construction with auxiliary pole.
Background technology
The iron tower group adopts the method for the long cross-arm of auxiliary pole lifting comparatively extensive immediately; Auxiliary pole firm banking (application number: 201010276814.X) well solved the fixing of auxiliary pole and iron tower cross-arm angle steel; But the precondition of using is on iron tower cross-arm angle steel, to be reserved with fixing hole, and reduced structural strength, the use aspect receives certain limitation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, convenient and practical, safe and reliable improved auxiliary pole firm banking.
The objective of the invention is to realize like this: a kind of improved auxiliary pole firm banking, rectangular plate upper surface is welded with two gripper shoes that laterally arrange, and rotating shaft is installed on two gripper shoes; Plate upper surface is welded with the 3rd screw rod and the 4th screw rod abreast, and all is coated with as the angle steel clevis piece that fixes with iron tower cross-arm angle steel on the 3rd, the 4th screw rod and is connected with nut; First screw rod and second screw rod are screwed on the base plate from the top down, and all are coated with as the angle steel clevis piece that fixes with iron tower cross-arm angle steel on first screw rod and second screw rod and are connected with nut.
The mutual alignment of above-mentioned first screw rod and the 3rd screw rod is that antarafacial intersects vertically, and the mutual alignment of second screw rod and the 4th screw rod is that antarafacial intersects vertically.
All be welded with reinforcing rib on above-mentioned two gripper shoes.
Be welded with two gripper shoes that laterally arrange on the base plate, the fix rotating shaft of auxiliary pole base of a usefulness is installed between two gripper shoes, floor level direction, vertical direction are respectively arranged with two as the screw rod and the fixture block that fix with iron tower cross-arm angle steel.
Compared with prior art, the invention has the beneficial effects as follows: during use, on the horizontal direction of iron tower cross-arm angle steel and vertical direction, adopt fixture block and steel tower corner iron to fix through nut respectively this base.Construction no longer need be on the iron tower cross-arm preformed hole, and simpler and easy, more convenient and fixing safe and reliable when installing.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are respectively front view of the present invention, left view and vertical view.
The specific embodiment
Fig. 1, Fig. 2 illustrate this improved auxiliary pole firm banking, and rectangular base plate 4 upper surfaces are welded with two gripper shoes that laterally arrange 2, and rotating shaft 1 is installed on two gripper shoes 2; Base plate 4 upper surfaces are welded with the 3rd screw rod 6c and the 4th screw rod 6d abreast, and all are coated with as the angle steel clevis piece that fixes with iron tower cross-arm angle steel on the 3rd, the 4th screw rod and are connected with nut; The first screw rod 6a and the second screw rod 6b are screwed on the base plate from the top down, and all are coated with as the angle steel clevis piece 8a, 8b, 8c, the 8d (totally 4) that fix with iron tower cross-arm angle steel on first screw rod and second screw rod and are connected with nut 7.The mutual alignment of the first screw rod 6a and the 3rd screw rod 6c is that antarafacial intersects vertically, and the mutual alignment of the second screw rod 6b and the 4th screw rod 6d is that antarafacial intersects vertically.Referring to Fig. 3, all be welded with reinforcing rib 3 on two gripper shoes 2.
Among Fig. 3, first, second screw rod is along the base plate long side direction and be positioned at the setting of base plate left side.Visible from Fig. 1, during use, iron tower cross-arm angle steel 5 is between side plate of fixture block and corresponding screw rod.
The present invention is mainly assembled by base plate, gripper shoe, stiffened panel, rotating shaft, (four) screw rod, (four) fixture block.Base plate, gripper shoe, stiffened panel are welded to connect each other, earlier rotating shaft are loaded onto during assembly welding, and postwelding requires rotating shaft to rotate flexibly.Two circular screwholes are arranged on the base plate, and screw rod passes screw, promotes fixture block through fastening nut and realizes the vertical fixing of base plate and iron tower cross-arm angle steel.Two screw rods of floor level direction welding promote the crosswise fixed that fixture block is realized base plate and iron tower cross-arm angle steel through fastening nut.Rotating shaft is used to connect auxiliary pole base.Need not reserve fixing hole on the iron tower cross-arm angle steel.
