Abstract
The utility model relates to a kind of sister block wire grip of electric transmission line erection, first pulley (1) of this wire grip and the second pulley (2) are fixed on the first chassis (5) by the first pulley bracket (3) and the second pulley bracket (4), coordinate with the first chassis (5) and be provided with the second chassis (6), first chassis (5) and the second chassis (6) are fixed together by connecting plate (7), second chassis (6) is provided with hanging ring (8), four angles on the second chassis (6) are respectively equipped with fixing hole (9), correspondingly with the second chassis (6) be provided with bottom plate (10), the upper fixing hole (9) of upper relative second chassis (6) of bottom plate (10) is provided with lower fixed hole (11), bottom plate (10) and the second chassis (6) can utilize bolt (12) to be fixed together.The utility model in use with tower bar cross-arm hanging point close together, hanging wire is convenient, and the stringing of angle pole is more laborsaving.
Description
Technical field
The utility model belongs to electric transmission line erection technical field of construction equipment, relates to a kind of sister block wire grip of electric transmission line erection specifically.
Background technology
In ultra-high-tension power transmission line erection process, must by the power transmission line tension between two tower bars, then mount on the insulator, what transmission line wire grip adopted mostly is single-sheaved block wire grip, and wire grip is located at below cross-arm, and power transmission line passes through pulley, manually drag line in below, power transmission line to be suspended on the hanging point above cross-arm, need upper and lower personnel to coordinate, just can be suspended to the appointment hanging point above cross-arm; Due to power transmission line and hanging wire point distant, hanging wire difficulty, time-consuming, effort; Stringing in particular for tower bar, angle tower bar is required great effort more.
Summary of the invention
The purpose of this utility model is the sister block wire grip of the electric transmission line erection providing a kind of structure simple, easy and simple to handle.Realizing the technical scheme that the purpose of this utility model takes is: a kind of sister block wire grip of electric transmission line erection, it is characterized in that: this wire grip is provided with the first pulley and the second pulley, first pulley and the second pulley are fixed on the first chassis by the first pulley bracket and the second pulley bracket, and the first described pulley and the second pulley are established on the same line.Coordinate with the first chassis and be provided with the second chassis, first chassis and the second chassis are fixed together by connecting plate, second chassis is provided with hanging ring, four angles on the second chassis are respectively equipped with fixing hole, correspondingly with the second chassis be provided with bottom plate, on bottom plate, the upper fixing hole on relative second chassis is provided with lower fixed hole.Bottom plate and the second chassis can profit be bolted together.
The utility model is be fixed on cross-arm in use, and snatch block is in the top of cross-arm, and power transmission line hanging point is below cross-arm, and with tower bar cross-arm hanging point close together, hanging wire is convenient.In addition, during straight line stringing, two pulleys can with the tension direction of power transmission line point-blank, during stringing for angle pole, can be that miter angle is strained by the tension direction of the tension direction of two pulleys and power transmission line, the stringing of angle pole be more laborsaving.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
In figure, the 1, first pulley, the 2, second pulley, the 3, first pulley bracket, the 4, second pulley bracket, the 5, first chassis, the 6, second chassis, 7, connecting plate, 8, hanging ring, 9, upper fixing hole, 10, bottom plate, 11, lower fixed hole, 12, bolt.
Embodiment
With reference to accompanying drawing, a kind of sister block wire grip of electric transmission line erection, it is characterized in that: this wire grip is provided with the first pulley 1 and the second pulley 2, first pulley 1 and the second pulley 2 are fixed on the first chassis 5 by the first pulley bracket 3 and the second pulley bracket 4, the first described pulley 1 and the second pulley 2 are established on the same line, coordinate with the first chassis 5 and be provided with the second chassis 6, first chassis 5 and the second chassis 6 are fixed together by connecting plate 7, second chassis 6 is provided with hanging ring 8, four angles on the second chassis 6 are respectively equipped with fixing hole 9, correspondingly with the second chassis 6 be provided with bottom plate 10, on bottom plate 10, the upper fixing hole 9 on relative second chassis 6 is provided with lower fixed hole 11.Bottom plate 10 and the second chassis 6 can utilize bolt 12 to be fixed together.
During use, utilize lifting appliance by hanging ring 8, the utility model to be hung the top of cross-arm, folder cross-arm is clipped in the middle and utilizes bolt 12 to be clamped on cross-arm by bottom plate 10 and the second chassis 6; First pulley 1 and the second pulley 2 are in above cross-arm, during for tangent tower bar, the stringing direction of two pulleys and the stringing direction of power transmission line are point-blank, power transmission line is located on two pulleys, during for angle tower bar, the stringing direction of two pulleys and the stringing direction of power transmission line are miter angle, and the other end of power transmission line is strained by the hauling machine or manpower traction being positioned at ground, and lead and ground are 45 degree to 60 degree angles.The new snatch block of this practicality is in the top of cross-arm, and power transmission line hanging point is below cross-arm, with tower bar cross-arm hanging point close together, laborsaving, works conveniently.During stringing for angle pole, can be that miter angle is strained by the tension direction of the tension direction of two pulleys and power transmission line, the stringing of angle pole be more laborsaving.
