The embodiment is as follows:

referring to fig. 1 and 2: the utility model provides a supplementary instrument of erectting of transmission line, including mounting bracket 101, the adjustable shelf 128 and hang and establish the subassembly, logical groove 103 has been seted up on mounting bracket 101, it is provided with adjustable shelf 128 in logical groove 103, all be provided with pulley 110 on mounting bracket 101 and the adjustable shelf 128, all be provided with ratchet 112 on two sets of pulley 110, two sets of ratchet 112 revolve to opposite, all be provided with protection casing 102 on mounting bracket 101 and the adjustable shelf 128, two sets of ratchet 112 set up respectively in two sets of protection casings 102, all be provided with fixed axle 129 on mounting bracket 101 and the adjustable shelf 128, all the activity is provided with jack catch 115 on two sets of fixed axle 129, two sets of jack catch 115 block respectively establishes on two sets of ratchet 112, all the cover is equipped with torsional spring 116 on two sets of fixed axle 129, two sets of torsional spring 116 set up respectively on two sets of jack catch 115, mounting bracket 101 top is provided with on hanging axle 109 and hangs and establishes the subassembly, it includes bearing seat 105 to hang and establish the subassembly.

In the process of line erection, the transmission conductor is prevented from contacting the ground or crossed obstacles such as charged bodies, crops, trees, buildings and the like between two iron towers, and the conductor needs to be tensioned by equipment; however, the currently used wire hanging device has no moving mechanism, so that the working difficulty is increased due to too large friction force during wire pulling operation, and even the transmission conductor is abraded due to friction, under the arrangement of the two groups of pulleys 110, the cable to be erected is arranged between the two groups of pulleys 110 in a penetrating manner, and then the wire pulling operation is performed, so that the friction force is reduced, and the working efficiency is improved; because the cable is erect the high altitude construction, the cable is often thicker, and its quality is heavier, if because of erect personnel's error hand smooth, when the grip is not enough, the cable can fall because of self gravity, influences the construction progress, falls to injure constructor by a crashing object even, and owing to wear to establish transmission of electricity cable and lean on pulley 110 rotatory transmission cable between two sets of pulleys 110, under ratchet 112 and jack catch 115's setting, prevent pulley 110 reversal, can avoid transmission of electricity cable to retrieve and drop.

During the use, establish the subassembly through hanging and fix this instrument in required position, pass the cable again between group's pulley 110, carry out the work of acting as go-between again, easy operation, convenient to use.

Referring to fig. 2, a counter bore 125 is formed in the bearing seat 105, a bearing 126 is disposed in the counter bore 125, the bearing 126 is disposed on the hanging shaft 109, a rectangular groove 127 is formed in the bearing seat 105, a fixing bolt 107 is threadedly connected to the hanging shaft 109, a fixing block 108 is disposed at one end of the fixing bolt 107, a limit block 123 is disposed on the fixing block 108, a limit groove 124 is formed in the rectangular groove 127, and the limit block 123 is disposed in the limit groove 124.

The transmission line is under pulley 110's traction, will remove between two adjacent iron towers, if pulley 110 can not the automatic adjustment direction, when transmission line and pulley 110 axis out of plumb appear, it is big to act as go-between this moment also can appear frictional force, lead to acting as go-between the difficulty, under bearing 126's setting, when transmission line and pulley 110 axis out of plumb appear, the adjustable shelf 128 can rotate the adjustment by oneself, guarantee that transmission line is perpendicular with pulley 110 axis, the resistance is reduced, fixing bolt 107 and fixing block 108's effect is fixed mounting bracket 101 in corresponding position, rotatory fixing bolt 107 drives fixing block 108 and firmly fixes mounting bracket 101, make it can not drop after the atress.

Referring to fig. 2, a guide rail 117 is disposed in the through groove 103, a stroke groove 106 is disposed on the movable frame 128, the guide rail 117 is disposed in the stroke groove 106, an adjusting stud 122 is connected to the mounting frame 101 by a thread, one end of the adjusting stud 122 is movably disposed on the movable frame 128, and a turntable 104 is disposed at the other end of the adjusting stud 122.

In order to meet the installation of power transmission conductors with different diameters, the guide rails 117 and the travel slots 106 are arranged so that the movable frame 128 can move in the mounting frame 101 to adjust the distance between the two sets of pulleys 110, thereby clamping power transmission conductors with different diameters. The specific operation is that the turntable 104 is rotated to increase the distance between the two groups of pulleys 110, the power transmission conductor penetrates between the two groups of pulleys 110, and then the turntable 104 is rotated to control the movable frame 128 to be close to the mounting frame 101, so that the distance between every two groups of pulleys 110 is gradually reduced until the power transmission conductor is clamped.

Referring to fig. 2, a locking assembly is disposed on the mounting frame 101, the locking assembly includes a fixed clamping block 118, a movable clamping block 120 is movably disposed on the fixed clamping block 118, a buckle 119 is disposed on the fixed clamping block 118, a latch 121 is disposed on the movable clamping block 120, the buckle 119 is clamped on the latch 121, and an adjusting stud 122 is disposed between the fixed clamping block 118 and the movable clamping block 120. The locking assembly is used for preventing the adjusting stud 122 from loosening and rotating due to larger stress of the movable frame 128 in the process of erecting the stay wire, if the movable frame 128 loosens, the clamping force of the two groups of pulleys 110 is reduced, and at the moment, after the movable frame 128 loosens the hand, the power transmission conductor can fall due to self-gravity. When needing to adjust, open locking Assembly for adjust the double-screw bolt 122 can rotate, thereby adjust, after adjusting corresponding position, establish buckle 119 card on latch 121, locking Assembly will adjust double-screw bolt 122 this moment and hug closely, adjust double-screw bolt 122 just can not be rotatory by oneself.
