Description
Technical Field
The invention belongs to the technical field of tension stringing construction of transmission and distribution wires, and particularly relates to a tension clamp paying-off pulley device.
Background
When the tension frame wire of the power transmission and distribution line is constructed, generally, when tension is paid off, the tension clamp cannot pass through a paying-off pulley due to the drainage plate, a net sleeve connector or a crimping traction head is generally adopted to pull the wire, and then the tension clamp is crimped by high-altitude wire breakage. This approach is time consuming, laborious, and particularly when important spans are being made, limited by the span time, and the control of the high-altitude crimping time is more stringent. The condition that the strain clamp passes through the paying-off pulley is not used in important crossing construction and conventional line construction.
Disclosure of Invention
The invention aims at the characteristics of the existing strain clamp and avoiding high-altitude crimping of the strain clamp, and provides a strain clamp paying-off pulley device, so that the strain clamp can smoothly pass through a pulley, the high-altitude crimping of the strain clamp is reduced, and the span paying-off time is effectively shortened.
In order to solve the technical problems, the invention adopts the following technical scheme: this unwrapping wire coaster device is crossed to strain clamp, including rotatory traction head, crank mechanism and the line nose connector that sets gradually, crank mechanism includes first main journal and the second main journal of concentric setting and eccentric upward set firmly in the eccentric connecting rod neck between first main journal and the second main journal, first main journal and rotatory traction head swivelling joint, the line nose connector includes the cavity connecting rod of being connected with the second main journal detachable to and the protrusion sets up the fin wing protective sheath on the cavity connecting rod, and the protrusion direction of fin wing protective sheath is unanimous with crank mechanism's eccentric direction.
The wire nose connector is formed by combining two semi-hollow connecting rods and a semi-fin protection sleeve which are symmetrically distributed.
And a jacking device is arranged below the eccentric connecting rod neck.
The jacking device is a pulley.
And a rotary protective sleeve is sleeved outside the eccentric connecting rod neck.
The beneficial effects of the invention are as follows: this pay off pulley device is crossed to strain clamp sets up crank mechanism and line nose connector cooperation, can make fin wing protective sheath automatic rotatory around the main journal, when through the slide, makes fin wing protective sheath automatic upwards, guarantees that the strain clamp passes through the coaster intact, accomplishes the strain clamp and passes through multi-base unwrapping wire coaster, reaches appointed mounted position, and then saves the operation of high altitude crimping, improves the efficiency of construction.

Detailed Description
The invention provides a strain clamp paying-off pulley device, which is shown in fig. 1 to 4, and comprises a rotary traction head 1, a crank mechanism 2 and a wire nose connector 3 which are sequentially arranged, wherein the crank mechanism 2 comprises a first main journal 4 and a second main journal 5 which are concentrically arranged, and an eccentric connecting rod neck 6 which is eccentrically and fixedly arranged between the first main journal 4 and the second main journal 5, the first main journal 4 is rotationally connected with the rotary traction head 1, the wire nose connector 3 comprises a hollow connecting rod 7 which is detachably connected with the second main journal 5, and a fin protection sleeve 8 which is convexly arranged on the hollow connecting rod 7, and the protruding direction of the fin protection sleeve 8 is consistent with the eccentric direction of the crank mechanism 2. In this embodiment, in order to facilitate assembly and disassembly of the strain clamp, the wire-nose connector is formed by combining two symmetrically distributed semi-hollow connecting rods and a semi-fin protection sleeve; when the anti-strain clamp is used, the strain clamp is placed in the semi-hollow connecting rod, the drainage plate of the strain clamp is placed in the semi-fin protection sleeve, and then the other half of the hollow connecting rod and the semi-fin protection sleeve are combined and fixed with each other. Preferably, the eccentric connecting rod neck can be used independently, and the outer periphery of the eccentric connecting rod neck can also be sleeved with a rotary protective sleeve 9. Meanwhile, in order to facilitate the rotation of the crankshaft mechanism 2 and the wire nose connector 3, a jacking device 10, in this embodiment, a pulley, is disposed below the eccentric connecting rod neck 6.
Before the strain clamp is transported and installed, the strain clamp is crimped on the ground, then the strain clamp is installed in the wire nose connector 3, the drainage plate 11 of the strain clamp is placed in the fin protection sleeve 8, and then the wire nose connector 3 is fixedly connected with the crankshaft mechanism 2, so that the assembly of the strain clamp paying-off pulley device is completed. When the strain clamp is conveyed, the traction wire is connected to the rotary traction head, the device is pulled to move forwards, when the strain clamp passes through the paying-off pulley device and passes through the pulley, if the fin protection sleeve does not point upwards, the rotary traction head drives the crank mechanism and the fin protection sleeve to rotate under the action of gravity, traction force and wire tension until the rotary torque generated under the action of the gravity, traction force and wire tension is zero, namely the fin protection sleeve points upwards in accordance with the eccentric direction of the crank mechanism, and the state of balanced stress is achieved. During conveying, supporting frames are arranged on two sides of the pulley, a certain distance is arranged above the pulley, and the fin protection sleeve can penetrate through the pulley, so that the strain clamp can penetrate through the pulley intact. The pay-off pulley device for the strain clamp can omit the operation of high-altitude compression joint of the strain clamp, is used for effectively shortening the crossing construction time when crossing is important, reduces the influence on important crossing of a crossed high-speed railway, a power line and the like, and has good economic and social benefits.
