It includes connecting bolt, gyro wheel, roller shaft and gyro wheel frame, wherein the gyro wheel frame is a mouthful font structure, a roller shaft is run through at the center of gyro wheel, and install at gyro wheel frame both sides limit middle part with the rotation mode at the both ends of roller shaft, topside middle part on the gyro wheel frame is connected to connecting bolt's lower extreme, and the upper end is fixed on the cross arm. The utility model provides a tightly, take out stitches and use coaster has following beneficial effect: (1 )Contained angle between cross arm and turn -buckle and coaster has been reduced. (2 )Cross arm and only 300 millimeters pulley distances can reduce to pull when consequently tightening up the wire and the cross arm damage. (3 )The price is no longer than 160 yuan to can the used repeatedly several. (4 )It is simple and efficient to be under construction, and the security performance is good.
Description
Technical field
The utility model belongs to electric power system servicing unit technical field, particularly relate to a kind of tight, take out stitches and use coaster.
Background technology
In power overhead network work progress, sometimes need to loosen wire according to construction requirement or tighten up.Fig. 1 is a kind of tight unwrapping wire process schematic conventional at present.Fig. 2 is the cross-arm, rope link and the coaster connection status schematic diagram that use at present.As shown in Figure 1 and Figure 2, overhead transmission line normally arranges many steel towers 1 along erection path standoff distance on the ground, steel tower 1 is arranged many cross-arms 2, cross-arm 2 is arranged insulator 3, three-phase conducting wire 4 is connected between the corresponding insulator 3 on adjacent two steel towers 1.Now be described to loosen wire, when needs loosen a certain phase conductor, first the upper end of steel wire loop 8 is fixed on cross-arm 2, then a coaster 9 is hung in the lower end of steel wire loop 8, the pull rope 5 from pulling equipment 10 is made to be connected with the wire grip 6 be arranged on wire 4 through after coaster 9 afterwards, and between wire grip 6 and a certain insulator 3, wire clamp 7 is installed, then pulling equipment 10 is utilized to strain pull rope 5, wire 4 is acted on by pull rope 5 and wire grip 6, it is loosening that traction wire 4 makes wire clamp 7 and contiguous insulator 3 place produce, dismountable connection between this insulator 3 and cross-arm 2 thus.Loosen pulling equipment 10 afterwards, thus loosen wire 4.But, there is following point in this tight line-putting method: as mentioned above, because coaster 9 is connected with cross-arm 2 by steel wire loop 8, therefore the distance between cross-arm 2 and coaster 9 top sheave is 600 millimeters, pulley distance of wire 4 connects gold utensil 1.2 meters, in addition the structural design of coaster 9 is not too reasonable, therefore cross-arm 2 just defines with wire grip 6 and pulley room and grips angle, thus the traction excessively of wire 4 will be increased when tightening up pull rope 5, cross-arm 2 will be caused like this to occur distortion, thus cause three-phase conducting wire 4 sag uneven, steel tower 1 top displacement increases, larger to steel tower 1 structural compromise.And a replacing three-phase cross-arm just needs 60,000 yuan in this case.
Summary of the invention
In order to solve the problem, the purpose of this utility model be to provide a kind of tight, take out stitches and use coaster.
In order to achieve the above object, that the utility model provides is tight, taking out stitches comprises connecting bolt, roller, roller shaft and turning rolls with coaster; Wherein turning rolls is square shape structure; A roller shaft is run through at the center of roller, and the two ends of roller shaft are arranged in the middle part of turning rolls dual-side with rotating manner; The lower end of connecting bolt is connected in the middle part of turning rolls upper topside, and upper end is fixed on cross-arm.
Described tight, take out stitches with the height of coaster be 300mm, width is 80mm, thickness is 40mm, wherein the maximum gauge of roller is 80mm, and connecting bolt is φ 16 × 145mm.
The utility model provide tight, taking out stitches has following beneficial effect with coaster:
(1) cross-arm is reduced and angle between wire grip and coaster.
(2) cross-arm and pulley distance only 300 millimeters, therefore can reduce traction during stringing lead and cross-arm damages.
(3) price is no more than 160 yuan, and can reuse for several times.
(4) easy construction is quick, and security performance is good.

Fig. 2 is the cross-arm, rope link and the coaster connection status schematic diagram that use at present.
Fig. 3 for the utility model provide tight, take out stitches and use pulley structure front view.
Fig. 4 for the utility model provide tight, take out stitches and use pulley structure end view.
Tight, take out stitches use coaster and cross-arm connection status schematic diagram that Fig. 5 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments to the utility model provide tight, taking out stitches is described in detail with coaster.The parts identical with prior art adopt identical drawing reference numeral.
As shown in Fig. 3-Fig. 5, the utility model provide tight, taking out stitches comprises connecting bolt 11, roller 12, roller shaft 13 and turning rolls 14 with coaster 15; Wherein turning rolls 14 is square shape structure; A roller shaft 13 is run through at the center of roller 12, and the two ends of roller shaft 13 are arranged in the middle part of turning rolls 14 dual-side with rotating manner; The lower end of connecting bolt 11 is connected in the middle part of turning rolls 14 upper topside, and upper end is fixed on cross-arm 2.
Described tight, take out stitches with the height of coaster 15 be 300mm, width is 80mm, thickness is 40mm, wherein the maximum gauge of roller 12 is 80mm, and connecting bolt 11 is φ 16 × 145mm.
Now the utility model is provided tight, taking out stitches is described below with coaster installation method: only the non-stress bolt on cross-arm 2 need be pulled down, this is tight, taking out stitches penetrates non-stress bolt screw with connecting bolt 11 upper end on coaster 15, then use nut screwing clamping, tight, fixing with coaster 15 of taking out stitches can be completed.
