Embodiment
Like Fig. 1, shown in 2; A kind of nut blocking ring hook is made up of screw rod steel loop 1 and blind nut 5, it is characterized in that: one side screw rod steel loop 1 be provided with opening 4; One end of opening 4 is a lag bolt bar 6; The other end of opening 4 is a stay bolt bar 3, and lag bolt bar 6 is the bolt shank perfectly straight, concentric, that pitch is identical with stay bolt bar 3, and the bolt screw thread on the stay bolt bar 3 is longer than the bolt screw thread on the lag bolt bar 6; Solder up 2 is at the root position of stay bolt bar 3, and blind nut 5 passes through its inner internal thread spinning on stay bolt bar 3, and locatees at solder up 2 places; Blind nut 5 is to the direction swing offset of lag bolt bar 6, treat blind nut 5 also simultaneously spinning in 6 last times of lag bolt bar, sealing opening 4; Screw rod steel loop 1 is formed closed bail; Opposite spin blind nut 5 treats that blind nut 5 gets back to 3 last times of stay bolt bar fully, and the opening 4 of screw rod steel loop 1 is opened.One end of the outer circumferential face of said blind nut 5 is a regular hexagon, and its other end is circular.The screw thread screw thread of lag bolt bar 6, stay bolt bar 3 and blind nut 5 is regular screw threads, fine thread or trapezoidal thread.The profile of said blocking ring hook is oval, square, triangle or polygonal.The profile of said blocking ring hook is oval.The screw rod steel loop 1 and the blind nut 5 of said blocking ring hook are processed by the high-quality steel.The outer circumferential face of the ring wall of said screw rod steel loop 1 is circular.
Like Fig. 3, shown in 4, a kind of production method of nut blocking ring hook is characterized in that its making step is:
(A) choose the straight steel rod of a measured length, an end of straight steel rod is manufactured the bolt shank of measured length;
(B) make blind nut 5, the screw thread threads engaged of bolt shank on its internal whorl and the straight steel rod, an end of the outer circumferential face of blind nut 5 is processed regular hexagon, and its other end is processed circle;
(C) will make good blind nut 5 spinnings on the bolt shank of straight steel rod, then, guarantee that its bolt shank is not bent under the situation of distortion, straight steel rod will be surrounded the enclosed bail, and in solder up 2 place's solder ups;
(D) blind nut 5 with spinning on the bolt shank rotates to solder up 2 places, on the bolt shank that blind nut 5 is abdicated, opens the opening 4 of a measured length near blind nut 5, and nut blocking ring hook is processed.
The solder up 2 of this nut blocking ring hook is arranged on the elbow of screw rod steel loop 1.Because of on know-why, when later welding, that turns one's head is stressed less, not fragile; So, let straight steel rod in the elbow solder up, the firm welding later of nut blocking ring hook, the pulling force of its screw rod steel loop wall can reach the technical requirements of the design pulling force of nut blocking ring hook.
This nut blocking ring hook, commonly used a kind of be oval blocking ring hook, among the embodiment as shown in Figure 1; It is the thick round steel of 10mm that screw rod steel loop 1 adopts diameter; The pulling force of this nut blocking ring hook can reach 30KN, and this blocking ring hook is applicable on the safety protection device of high-lift operation, as; Safety strip, secondary safety protection rope, application number are 200910074506.6; Publication number is the sealing etc. of the disclosed ball-ring pulley of patent application of CN101576154, and in addition, this blocking ring hook also is suitable on other enclosed connection set.
Below with the application of nut blocking ring hook on ball-ring pulley, and the utilization of ball-ring pulley when the operation of power transmission lines overhauling lead be example, is elaborated.
As shown in Figure 5; When this nut blocking ring hook is used on second protection device ball-ring pulley; With processing the second protection deragger with rope sling 7 connections in the middle of two nut blocking ring hooks; Then, securely the switch door locking of ball-ring pulley is lived with the nut blocking ring hook of second protection deragger one end.The rope sling 7 of second protection deragger can be selected nylon rope sling or stone dead wire rope sling for use.
When the operation of power transmission lines overhauling lead, ball-ring pulley is suspended on the aerial earth wire, the nut blocking ring hook of second protection deragger one end is opened; Hook is lived two switch rings 8 of ball-ring pulley, then, and rotary seal nut 5; Close the opening 4 of nut blocking ring hook, and, do not allow blind nut 5 to move back button with the fastening blind nut 5 of spanner; Two switch rings 8 of ball-ring pulley are latched in the bail to deviate from securely, and like this, ball-ring pulley is just sealed securely and hangs on the aerial earth wire.At last, the nut blocking ring hook of the second protection deragger the other end is connected with the worker's of operation on the power transmission lines overhauling lead safety strip steel loop, just can plays secondary personal safety protective action the worker.
After power transmission lines overhauling lead work operations finished, rotary seal nut 5 was opened the opening 4 of nut blocking ring hook, and a switch ring 8 of ball-ring pulley is withdrawed from from opening 4, and the switch open of ball-ring pulley can be removed ball-ring pulley from aerial earth wire.
