Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention will be combined to clearly and completely describe the technical solutions of the embodiments of the present invention.

Example (b):

referring to fig. 1 and 2: the utility model provides a turn-buckle that defeated transformer electric wire used, including atress frame 101, rocking arm 108 and the subassembly of acting as go-between, be provided with spool 107 on the atress frame 101, rocking arm 108 sets up in spool 107 one end, the groove 114 has been accomodate to having seted up on rocking arm 108, spout 117 has been seted up on rocking arm 108, accomodate groove 114 and spout 117 intercommunication, it is provided with extension arm 110 in the groove 114 to accomodate, extension arm 110 one end is provided with stopper 109, stopper 109 sets up in spout 117, threaded connection has fastening bolt 116 on rocking arm 108, fastening bolt 116 and extension arm 110 contact, the subassembly of acting as go-between includes wire tightening steel cable 118 and two sets of couple 104, wire tightening steel cable 118 sets up on spool 107, two sets of couple 104 set up respectively at atress frame 101 both ends.

In the field circuit erection work, a wire tightener is needed; generally be high altitude construction at the staff that uses the turn-buckle, because the particularity of aerial operation, turn-buckle spanner overlength, be unfavorable for operating personnel to carry in the field and high altitude construction, too short consumes the staff physical stamina greatly again in the use, under the setting of rocking arm 108 and extension arm 110, adjust under the operational environment of difference, in order to satisfy different length demands, under fastening bolt 116's setting, fix after adjusting length, spout 117 and stopper 109 are used for preventing adjusting the length in-process, the groove 114 is accomodate in the extension arm 110 roll-off, cause personnel's injury.

During the use, hang two sets of couples 104 on the position of required operation and the taut electric wire of needs respectively earlier, adjust the length of rocking arm 108 as required again, during the regulation, unscrew fastening bolt 116 earlier, control extension arm 110 is in accomodating groove 114 position, after adjusting required position, can rotate rocking arm 108 and drive spool 107 and retrieve tight line steel cable 118 with fastening bolt 116 screws up.

Referring to fig. 2, a fixed shaft 102 is disposed on the stress frame 101, the other end of a wire tightening rope 118 is disposed on the fixed shaft 102, a pulley 119 is hung on the wire tightening rope 118, the pulley 119 is disposed on the movable block 103, a rotating block 120 is disposed on the movable block 103, and a set of hooks 104 is disposed on the rotating block 120.

Under the setting of pulley 119, can effectively reduce the required power in the tight line in-process, alleviate working strength, the effect of turning block 120 can be adjusted couple 104 and conveniently hangs the electric wire of different positions.

Referring to fig. 2, a guide assembly is disposed at one end of the stress frame 101, the guide assembly includes a guide block 106, one end of the stress frame 101 is provided with an arc groove a105, the guide block 106 is movably disposed in the arc groove a105, the guide block 106 is provided with an arc groove B127, and the other set of hooks 104 is movably disposed in the arc groove B127.

When the position of the hook 104 of the wire tightener and the tightening direction of the wire tightening steel rope 118 are not on the same straight line, force loss is easy to generate, larger force needs to be applied to the rocker arm 108, the workload is increased, and meanwhile, the tightening force of the steel rope can be influenced; under guide assembly's setting, arc groove A105 and arc groove B127's effect lies in can both guaranteeing under arbitrary angle that couple 104 position and tight line steel cable 118 tighten up the direction on same straight line, and at the tight line in-process, guide block 106 is at arc groove A105 internalization, and couple 104 is at arc groove B127 internalization, and diversified tight line work is realized in the cooperation of two sets of grooves.

Referring to fig. 4, one end of the spool 107 is provided with an anti-reverse rotation assembly, the anti-reverse rotation assembly includes a ratchet 124, the stressed frame 101 is provided with a short shaft 123, the short shaft 123 is provided with a jaw 121, the jaw 121 is clamped on the ratchet 124, the short shaft 123 is sleeved with a torsion spring 122, one end of the torsion spring 122 is arranged on the stressed frame 101, and the other end of the torsion spring 122 is arranged on the jaw 121.

Because the resilience force is larger during tensioning under the action of the reaction force in the wire tensioning process, if the rocker arm 108 is reversed due to small strength or fatigue failure of workers, the workers are easily injured, and under the arrangement of the reversion preventing component, the rocker arm 108 is prevented from being reversed and injuring the workers; when the rotating rocker arm 108 works in a tightening mode, the claw 121 is clamped on the ratchet wheel 124 at the moment of action of the torsion spring 122, and when the ratchet wheel 124 rotates reversely, the claw 121 limits the rotation of the rocker arm 108, so that people are effectively prevented from being injured by the reverse rotation of the rocker arm 108.

Referring to fig. 4, a through hole 126 is formed in the force-bearing frame 101, a limiting component is arranged in the through hole 126, the limiting component includes a limiting shaft 128, a compression spring 130 is sleeved on the limiting shaft 128, a limiting hole 125 is formed in the rocker arm 108, one end of the limiting shaft 128 is clamped in the limiting hole 125, a positioning block 129 is arranged on the limiting shaft 128, an upright post 131 is arranged on the force-bearing frame 101, and the positioning block 129 is clamped on the upright post 131.

When high altitude construction, it is more difficult to carry the instrument, if the rocking arm 108 is unset during carrying and rocks easily, bring unnecessary trouble for the staff, under the setting of spacing subassembly, fix rocking arm 108 in the non-use process, concrete operation is, under compression spring 130's effect, in spacing hole 125 is gone into with spacing axle 128 top, the realization is fixed to rocking arm 108, use as required, pull out spacing axle 128, and it is rotatory, make locating piece 129 card on spacing axle 128 establish on stand 131, spacing axle 128 will be restricted to remove this moment, rocking arm 108 can rotate.

In some embodiments, referring to fig. 2, one end of the extension arm 110 is provided with a through slot 111, a handle 113 is movably disposed in the through slot 111, and a rubber sleeve 112 is sleeved on the handle 113.
