Abstract
A roller type rotating suspension clamp for transmission lines is characterized in that an upper roller (1) and a lower roller (5) are positioned between a front clamping plate (7) and a rear clamping plate (6), a roller shaft (8) is arranged at the central position of the upper roller (1) and the lower roller (5), the front clamping plate (7) and the rear clamping plate (6), emerging at both ends of the roller shaft (8) are tightened with bolts to combine and fix the front clamping plate (7) and the rear clamping plate (6) as well as the rollers.
Description
Technical field:
The utility model relates to the suspension gold utensil of transmission line, relates in particular to the movable suspension clamp of transmission line roller type.
Background technology:
The transmission line suspension clamp of prior art adopts stationary structure, by the screwing force fixing cord of bolt.Lead changes when excessive when running into unbalanced tensile force, because of can not slip can cause the suspension insulator wide-angle tilt.Impaired in order to prevent that shaft tower from being drawn, usually the method that adopts is earlier with after the line outage, and the maintenance personal climbs on the shaft tower, unclamps bolt, adjusts lead, and retorque is fixed again.Occurred the bank that subsides on ground,, just needed in 3 to 5 days at interval to adjust once, wasted time and energy very much, influenced power supply safety in the coal mining activation phase.
The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of transmission line roller type movable suspension clamp, moved along the lead direction by tension force to cause that insulator string tilts to solve suspension clamp that prior art exists, thereby influence the problem of iron tower safety.
The movable suspension clamp of transmission line roller type described in the utility model includes upper roller, bottom roller, insulator string connecting bolt, clamping plate, upper roller shaft, bottom roller axle, lead security bar and R groove and forms.The utility model is hung below the electric transmission line isolator string, be used to guide and support and lead () the suspension gold utensil of line.What the movable suspension clamp of roller type was connected with insulator string is the insulator string connecting bolt, and this bolt is arranged on the upper end of connecting plate, and the lower end of connecting plate is connected with clamping plate.Said clamping plate are divided into corresponding two, are divided into front plate and rear plate, at the two clamping plates of correspondence, promptly between front plate and the rear plate, are provided with upper roller and bottom roller.The center of upper roller and bottom roller is provided with roller shaft, and front plate and rear plate are exposed in the two ends of roller shaft, tightens with bolt, just front plate, rear plate and the combination of each roller is fixed together.The wheel face of said upper roller and bottom roller is provided with the R groove, the R groove correspondence of two rollers, can be combined into one and be used to penetrate and lead () circular hole of line.For guardwire better, in the circular hole that corresponding R groove forms, be provided with the lead security bar, lead then passes from the lead security bar.Said lead security bar can be an aluminium armor tape, also can adopt other material, and its purpose all is lead is carried out better and more effective protection.But if the lead security bar is not set, and also be feasible, be some shortcoming of protection to lead.
The bottom roller axle passes bottom roller and is fixed in the fixing hole on the clamping plate, screws on nut, lead () line puts in the R groove of bottom roller, upper roller is pressed in leads again () on the line, screw on nut and tighten, reach and prevent to lead () line jumps out the purpose of roller R groove.Lead () line changes by unbalanced tensile force and when acquiring a certain degree, upper roller of the present utility model and bottom roller roll, the insulator string that the movable suspension clamp of this roller type is housed is along the lead slippage, and in time get back to the original vertical position, wide-angle tilt does not take place in insulator string, has reduced effectively number of times is adjusted in the power failure of transmission line.
The utility model overall structure is simple, installs and safe and convenient to use, has solved to be subjected to the suitable lead direction of tension force to move the problem that causes insulator string obliquity effects shaft tower safety.
Description of drawings:
Embodiment:
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: the movable suspension clamp of transmission line roller type described in the utility model includes upper roller 1, insulator string connecting bolt 2, connecting plate 3, lead security bar 4, bottom roller 5, rear plate 6, front plate 7 and roller shaft 8 and forms.The utility model is hung below the electric transmission line isolator string, be used to guide and support and lead () the suspension gold utensil of line.What the movable suspension clamp of roller type was connected with insulator string is insulator string connecting bolt 2, and insulator string connecting bolt 2 is arranged on the upper end of connecting plate 3, and the lower end of connecting plate 3 is connected with clamping plate.Said clamping plate are divided into corresponding two, are divided into front plate 7 and rear plate 6, at the two clamping plates of correspondence, promptly between front plate 7 and the rear plate 6, are provided with upper roller 1 and bottom roller 5.The center of upper roller 1 and bottom roller 5 is provided with roller shaft 8, and front plate 7 and rear plate 6 are exposed in the two ends of roller shaft 8, tightens with bolt, just front plate 7, rear plate 6 and the combination of each roller is fixed together.The wheel face of said upper roller 1 and bottom roller 5 is provided with the R groove, the R groove correspondence of two rollers, can be combined into one and be used to penetrate and lead () circular hole of line.For guardwire better, in the circular hole that corresponding R groove forms, be provided with lead security bar 4, lead then passes from lead security bar 4.Said lead security bar 4 can be an aluminium armor tape, also can adopt other material, and its purpose all is lead is carried out better and more effective protection.But if lead security bar 4 is not set, and also be feasible, be some shortcoming of protection to lead.The bottom roller axle passes bottom roller 5 and is fixed in the fixing hole on the clamping plate, screw on nut, lead () line puts in the R groove of bottom roller 5, again upper roller 1 is pressed in and leads () on the line, also can be described as be pressed in be surrounded by the leading of lead security bar 4 () on the line, screw on nut and tighten, reach and prevent to lead () line jumps out the purpose of roller R groove.Lead () line changes by unbalanced tensile force and when acquiring a certain degree, upper roller 1 of the present utility model and bottom roller 5 roll, the insulator string that the movable suspension clamp of this roller type is housed is along the lead slippage, and in time get back to the original vertical position, wide-angle tilt does not take place in insulator string, has just reduced effectively yet number of times is adjusted in the power failure of transmission line.The utility model overall structure is simple, installs and safe and convenient to use, has solved to be subjected to the suitable lead direction of tension force to move the problem that causes insulator string obliquity effects shaft tower safety.
