Description
Technical field
The invention belongs to transmission and distribution line construction under tension stringing technical field, more particularly to a kind of strain clamp crosses releasing pulley
Device.
Background technology
During electric line construction under tension stringing, typically in tension stringing, strain clamp is due to there is drainage plate can not
By releasing pulley, typically using mesh sheath connector or compression joint type drawing head traction wire, then high-altitude broken string crimps strain insulator again
Wire clamp.This kind of mode is time-consuming, laborious, especially in important leap, is limited by across the time, marcottage time control
It is more strict.In important crossing construction and conventional line construction, the situation that strain clamp crosses releasing pulley was not used.
The content of the invention
The purpose of the present invention is the characteristics of being directed to current existing strain clamp and avoids marcottage strain clamp, there is provided one
Kind strain clamp crosses releasing pulley device, strain clamp is passed through coaster, reduces marcottage strain clamp, effectively contracting
It is short to cross over the unwrapping wire time.
To solve above technical problem, the technical solution adopted by the present invention is：The strain clamp crosses releasing pulley device, bag
The rotation traction traction head set gradually, crank mechanism and line nose connector are included, the crank mechanism includes the first master being arranged concentrically
Axle journal and the second trunnion and the eccentric eccentric ratio neck for being fixedly arranged on the first trunnion and the second main shaft collar upwards, described the
One trunnion is rotatably connected with rotation traction traction head, and the line nose connector includes hollow with the second trunnion detachable connection
Connecting rod, and protrusion are arranged on the fin wing protective case in hollow connecting rod, and the protrusion direction of fin wing protective case and bent axle machine
The eccentric direction of structure is consistent.
The line nose connector is combined by two symmetrical semi-hollow connecting rods and half fin wing protective case.
Jacking apparatus is equipped below the eccentric ratio neck.
The jacking apparatus is coaster.
Rotation protective case is arranged with outside the eccentric ratio neck.
The beneficial effects of the invention are as follows：The strain clamp crosses releasing pulley device, and crank mechanism and line nose connector are matched somebody with somebody
Close and set, fin wing protective case can be made to be rotated automatically around trunnion, when passing through coaster, make fin wing protective case automatically upward, ensure resistance to
Bracing cable folder intactly by coaster, completes strain clamp by more base releasing pulleys, reaches designated mounting position, and then save
The operation of marcottage is gone, improves efficiency of construction.

Fig. 2 is the structural representation of crankshaft structure；
Fig. 3 is the structural representation of strain clamp；
Fig. 4 is the present invention and the installation diagram of strain clamp.
Embodiment
The invention provides a kind of strain clamp to cross releasing pulley device, and as shown in Figures 1 to 4, the strain clamp, which is crossed, to be put
Line tackle arrangement, which includes the rotation traction traction that sets gradually first 1, crank mechanism 2 and line nose connector 3, the crank mechanism 2, to be included
The first trunnion 4 and the second trunnion 5 and bias being arranged concentrically are fixedly arranged between the first trunnion 4 and the second trunnion 5
Eccentric ratio neck 6, first trunnion 4 are rotatably connected with rotation traction traction first 1, and the line nose connector 3 includes and the second master
The hollow connecting rod 7 of the detachable connection of axle journal 5, and protrusion are arranged on the fin wing protective case 8 in hollow connecting rod 7, and fin
The protrusion direction of wing protective case 8 is consistent with the eccentric direction of crank mechanism 2.In the present embodiment, for the ease of the resistance to bracing cable of handling
Folder, the line nose connector are combined by two symmetrical semi-hollow connecting rods and half fin wing protective case；In use, will
Strain clamp is positioned in semi-hollow connecting rod, and the drainage plate of strain clamp is placed in half fin wing protective case, then will be another
One semi-hollow connecting rod and half fin wing protective case fixation in combination.Preferably, the eccentric ratio neck can be used alone, and also may be used
Rotation protective case 9 is arranged in its periphery.Meanwhile rotated for the ease of crank mechanism 2 and line nose connector 3, the eccentric ratio
The lower section of neck 6 is equipped with jacking apparatus 10, and in the present embodiment, jacking apparatus is coaster.
Before installation strain clamp is transported, strain clamp is crimped on ground completed first, then fill strain clamp
Enter in line nose connector 3, and the drainage plate 11 of strain clamp be positioned in fin wing protective case 8, then by line nose connector 3 with
Crank mechanism 2 is fixedly connected, that is, completes the assembling that strain clamp crosses releasing pulley device.When conveying strain clamp, rotation is led
Draught line is connected on leader, pulls the device to move forward, when strain clamp, which crosses releasing pulley device, passes through coaster, if fin
Wing protective case is not pointed towards to then by rotation traction traction headband dynamic crankshaft machine in the presence of gravity, tractive force and wire tension
Structure and fin wing protective case rotate, until because rotation torque caused by the effect of gravity, tractive force and wire tension is zero, i.e.,
The fin wing protective case state for pointing up, reaching stress balance consistent with the eccentric direction of crank mechanism.During conveying, coaster both sides
Provided with support frame, and support frame is provided with certain spacing above coaster, ensures that fin wing protective case can pass through, and then make strain insulator
Wire clamp intactly passes through coaster.The strain clamp crosses releasing pulley device, can save behaviour of the strain clamp in marcottage
Make, during for important leap, effectively shorten the crossing construction time, reduce important to high-speed railway, the power circuit etc. being spanned
The influence of leap, there is good economic and social benefit.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changes
Change and improvement is both fallen within the range of claimed invention.The claimed scope of the invention is by appended claims and is equal
Thing defines.
