Abstract
The utility model discloses an anti-tension device of an assembled iron towel which comprises a rail (1), a screw mandrel (2), a draw-in gear (3) and the screw mandrel (4) which is fixed on the middle of the rail (1). The anti-tension device is provided with two screw mandrels that are respectively inserted into both ends of the rail (1) and have threaded connection with the rail (1). When then rail (1) turns, two screw mandrels (2) move in opposite directions. The draw-in gear (3) is fixed on the outer end of each screw mandrel (2). The anti-tension device is light, portable, safe and reliable. In addition, the anti-tension device is easy to be operated without assembling and has high operation change rate as well as long service life without requiring maintenance.
Description
Technical field
The utility model relates to the employed tight anti-device of a kind of assembling iron tower of power transmission line.
Background technology
When the iron tower of transmission line of electricity need be assembled, when needing to be fastenedly connected between the iron tower column foot assembly, well clamping between them sometimes, only by manpower it closely being connected wastes time and energy, and can not guarantee safety and firmness, influences the normal operation of transmission line of electricity.
Technical scheme
For solving the problem of above existence, the utility model provides a kind of assembling iron tower tight anti-device, and its technical scheme of taking is:
This tight anti-device comprises cross bar, screw mandrel, dop and leading screw, and the centre position of cross bar is fixed with leading screw, and screw mandrel is provided with two, insert the two ends of cross bar respectively and be threaded with cross bar, when cross bar rotated, the traffic direction of two screw mandrels was opposite, and the outer end of each screw mandrel is fixed with dop.
Be fixed with extension rod between the outer end of each screw mandrel and the dop.
Drive cross bar by leading screw and rotate, but screw mandrel precession or back-out, thus by dop the vertical rod of iron tower is partly strutted or strains, help closely being connected with other parts.
Use this tight anti-device time saving and energy saving, shorten circuit and stop electric power feeding time, reduction is stepped on bar T and is made personnel labor intensity greatly, has improved operating efficiency, and safety and firmness, significantly reduces potential safety hazard.This tight anti-device is in light weight, carries light, safe and reliable; Easy and simple to handle, exempt from assembling, the efficient height is changed in operation; Long service life, non-maintaining.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, leading screw 4 is fixed on the centre position of cross bar 1, vertical with cross bar 1, screw mandrel 2 has identical two, and they insert the two ends, the left and right sides of the cross bar 1 of hollow respectively, and and cross bar 1 is threaded, when cross bar 1 rotated, the traffic direction of two screw mandrels 2 was opposite, and dop 3 also has identical two, the centre has " U " shape groove, and they are separately fixed at the outer end of each screw mandrel 2.
When using this tight anti-device, at first rotational lead screw 4 is adjusted the length of tight anti-device, till in " U " shape groove that the angle bar of iron tower vertical rod is snapped in dop 3, when other cross bar on vertical rod and the iron tower fixedly the time, by clockwise or rotate counterclockwise leading screw 4, increase or reduce the length of tight anti-device, by dop 3 vertical rod of iron tower is partly strutted or strains, it is closely contacted with the cross bar part, thereby can fasten them together with bolt.
When the length of this tight anti-device is not enough, can increase a pair of extension rod 5, extension rod 5 is fixed between the outer end and dop 3 of two screw mandrels 2.
Claims (2)
1, the tight anti-device of a kind of assembling iron tower, comprise cross bar (1), screw mandrel (2), dop (3) and leading screw (4), it is characterized in that: the centre position of cross bar (1) is fixed with leading screw (4), screw mandrel (2) is provided with two, insert the two ends of cross bar (1) respectively and be threaded with cross bar (1), when cross bar (1) rotated, the traffic direction of two screw mandrels (2) was opposite, and the outer end of each screw mandrel (2) all is fixed with dop (3).
2, the tight anti-device of assembling iron tower according to claim 1 is characterized in that: all be fixed with extension rod (5) between outer end of each screw mandrel (2) and the dop (3).
