Utility model content
Technical problem to be solved in the utility model provides one can single-line ground line card for above drawback, for fixing single earth connection, easy for installation, can one man operation Fast Installation, greatly facilitate workmen, flexibility strong adaptability, greatly improves construction schedule, has saved cost.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of single-line ground line card, comprise upper blocking seat, lower deck, pad, fastening bolt and clamp nut, described upper blocking seat comprises upper blocking seat main body, the section bar of upper blocking seat main body to be cross sectional shape be rectangle, upper blocking seat main body both sides are respectively provided with a upper clamping component and upper align member, described upper align member cross sectional shape is sector structure, the cross sectional shape of described upper clamping component is arc structure, the lower surface of upper clamping component is provided with the first groove of circular arc, the radius of described first groove is r1, and the right central angle of circular arc is a; Described lower deck comprises lower deck main body, the section bar of lower deck main body to be cross sectional shape be rectangle, lower deck main body both sides are respectively provided with a lower clamping component and lower align member, described lower align member cross sectional shape is sector structure, and the cross sectional shape of described lower clamping component is arc structure, and the upper surface of lower clamping component is provided with the second groove of circular arc, the radius of described second groove is r2, the right central angle of circular arc is b, r1 < r2, a > b; Described upper blocking seat and lower deck are oppositely arranged, and upper clamping component is corresponding with lower clamping component, and upper align member is corresponding with lower align member, and described fastening bolt from top to bottom through upper blocking seat, lower deck and pad, and is locked by clamp nut.
The beneficial effects of the utility model are:
1. when the utility model is installed and used, by fastening bolt from top to bottom successively through upper blocking seat, lower deck, pad and cable testing bridge, and use clamp nut pretension, in the cavity that second groove of the first groove and lower clamping component that single cable line card are entered upper clamping component is formed, then clamp nut is tightened, easy for installation, can earth connection be fixed on crane span structure, arbitrarily can adjust the installation direction of earth connection, can not cause damage to cable surface again, fail safe is high.
2. easy for installation, can one man operation Fast Installation, greatly facilitate workmen, the r2 of r1 < second groove of the first groove, and the central angle b of central angle a > second groove of the first groove, flexibility strong adaptability, can connect and fix the cable of different-diameter specification, connect more firm, not easily getting loose is fixed on cable testing bridge fast by it, greatly improve construction schedule, save cost.
3. go up align member and lower align member cooperatively interacts, cable can be made fixing more firm, more safe and reliable.
