Abstract
The utility model provides a fixing device with theft preventing function for pulling a line on an electricity transmitting and changing line tower and a special tool for assembly, disassembly and adjustment. The utility model is composed of a main body (1), a U-shaped screw wire (2) and a fixing screw nut (3). Two non-circular concave nests (9) are processed on the main body (1), and each concave nest can be a regular hexagon or a rectangle. The fixing screw nut (3) is enabled not to optionally rotate after falls into the non-circular concave nests. The special tool is provided with a lower supporting sleeve (4), a tensioning screw nut (5) and a tool upper sleeve (6), wherein, one end of the lower supporting sleeve (4) is provided with a tooth shape (7), and the inner cavity (8) of the other end of the lower supporting sleeve (4) is a hexagon inner cavity being able to rightly hold the fixing screw nut (3). The tooth shape (7) of the lower supporting sleeve (4) is engaged with a tooth shape of the tool upper sleeve (6), and the tensioning screw nut (5) is positioned in the inner cavity of the tool upper sleeve (6).
Description
The utility model is a kind of fixing and regulating device that is applicable to backguy on the power transmission and transformation line shaft tower, and special-purpose loading and unloading and adjustment instrument, and this device has antitheft, locking functions.
Backguy fixing and adjust and adopt wedge-type or pressure-connected type fixing device on the existing power transmission and transformation line shaft tower, wedge-type be by the U-shaped screw, nut, and chock and main body are formed, and pressure-connected type is made up of U-shaped screw, nut, arm-tie and aluminium hydraulic pressed connecting pipe.Owing to do not take anti-theft measure, U-shaped screw and nut are often stolen, cause power transmission and transformation line to fall tower, the bar that falls, and cause power outage.
The purpose of this utility model is to use general instrument can not unload nut on the U-shaped screw, prevents the loosening naturally of the stolen or nut of nut and U-shaped screw, to guarantee the safe operation of power transmission and transformation line.
The utility model on former anchorage shoe, keep off added antitheft, locking device, solution is to process two non-circular recesses on the main body of former anchorage shoe or arm-tie, and nut falls into recess after installing, under normal use condition, tension force in the backguy makes nut can't break away from recess, because recess has good cooperating with nut, and nut can not arbitrarily rotate in recess, therefore use general utility tool nut can't be unloaded simultaneously, thereby reach antitheft, locking purpose.Install, adjust and when unloading lower nut, all must use special tool.
That adopts on the main body is antitheft, retaining structure and arm-tie antitheft, the retaining structure is identical.Be example with the main body theft-prevention structure down below, be specifically described in conjunction with the accompanying drawings.
Fig. 1 is the phase diagram that installs and fixes behind the nut;
Fig. 2 is installation, the phase diagram when adjusting;
Fig. 3 is the side diagrammatic sketch of main body;
Fig. 4 is special tool lower support cover figure;
Fig. 5 is special tool lower support cover side diagrammatic sketch.
Respectively process a non-circular recess (9) in the main body that is installed with U-shaped screw (2) (1) diplopore end, set screw nut (3) is fallen in the non-circular recess (9), can not arbitrarily rotate.Special tool has lower support cover (4), tightening nut (5), cover (6) on the instrument.Lower support cover (4), cover (6) is non-circular hollow cylinder on the instrument, and U-shaped screw (2) is passed.Lower support cover (4) one ends have profile of tooth (7), the inner chamber of the other end (8) set screw nut (3) of can packing into, and can drive set screw nut (3) rotation, the degree of depth of inner chamber (8) is greater than the thickness of set screw nut (3), and cover (6) one ends have the profile of tooth that meshes with lower support cover (4) profile of tooth on the instrument.Cover (6) profile of tooth end inner chamber can drive tightening nut (5) rotation on the instrument.The inner chamber (8) of lower support cover (4) is the Hexagon inner chamber that set screw nut (3) just can have been packed into.
The working procedure of regulation fixing apparatus is.At first lower support cover (4) is inserted in U-shaped screw (2), tighten tightening nut (5), set screw nut (3) is deviate from recess gradually, enter instrument lower support cover (4) inner chamber (8), cover (6) makes cover (6) end face tooth engagement on lower support cover (4) and the instrument on the band good tool.Because cover (6) inner chamber can drive tightening nut (5) and set screw nut (3) rotation on lower support cover (4) and the instrument, at this moment, cover (6) becomes one on set screw nut (3), lower support cover (4), tightening nut (5), the instrument.Can use spanner to carry out the degree of tightness adjustment, when adjust to meet the requirements after, unload cover (6) on the instrument, back out tightening nut (5), unload lower support cover (4) again, observe set screw nut (3) and whether fall into recess, if do not enter, finely tune set screw nut (3) with spanner, because wire-drawing tension can make set screw nut (3) fall in the recess.
Non-circular recess is processed into regular hexagon, and the rectangular effect is best.
That adopts on the main body is antitheft, and anti-loose structure mainly is useful for newly-built power circuit backguy gold utensil product U-shaped strain clamp.Pressure-connected type anchor clamp and antitheft, the retaining of having built electric transmission line backguy gold utensil can adopt same principle.When adopting the pressure-connected type anchor clamp, can respectively add a non-circular recess at the diplopore end face of arm-tie.Also can on the end of main body, place a retaining plate that is processed with two non-circular recesses, be used on the electric transmission line backguy gold utensil.
The utility model is simple in structure, and is easy for operation, antitheft, and anti-loosening property is reliable, can prevent effectively that transmission line of electricity from falling the generation of tower, pole collapse accident, guarantees safe operation.
Claims (2)
1, a kind of anchorage shoe with anti-theft feature, by main body (1), U-shaped screw (2), set screw nut (3) is formed, it is characterized in that: process a non-circular recess (9) that set screw nut (3) can not arbitrarily be rotated on the diplopore end face of main body (1) respectively, non-circular recess (9) can be a regular hexagon, rectangular.
2, a kind of handling instrument with anchorage shoe of anti-theft feature, it is characterized in that: it is by lower support cover (4), tightening nut (5), cover (6) is formed on the instrument, wherein lower support cover (4) one ends have profile of tooth (7), the inner chamber of the other end (8) is the hexagon limit shape inner chamber that set screw nut (3) just can have been packed into, the profile of tooth of cover (6) engagement on the profile of tooth (7) of lower support cover (4) and the instrument, and tightening nut (5) overlaps in the inner chamber of (6) on instrument.
