Description
Technical field
The present invention relates to a kind of avoiding setting up using aerial earth wire extension pulley group job crosses over frame construction method.
Background technology
At present, power system is developed rapidly, so as to bring many transmission line of electricity improvement projects, most importantly in order to
Meet customer charge, carry out replacing transmission line wire, and change aerial condutor, be related to scissors crossing below many circuits
Problem, such as：Span transmission line, low-voltage distribution wire, highway, river, building construction etc. below circuit.The ground of these leaps
Side, then need to set up the crossing frames of many, and these crossing frames must before restringing is constructed, need many manpowers and
Time completes.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of simple construction, safe operation, can shorten the engineering time and stop
The electric time, time saving and energy saving, the utilization aerial earth wire extension pulley group job of saving operating expenses avoids setting up crosses over frame construction method.
Utilization aerial earth wire extension pulley group job according to the present invention avoids setting up crosses over frame construction method, and its step is such as
Under：
1st, scheduling job personnel first are on the shaft tower needed across near, and three axle assembly pulleys are hung over built on stilts ground by rod-rising tower
On line, the three axles assembly pulley is by top sheave frame, the top sheave being arranged on top sheave frame, gliding wheel carrier and is arranged on lower sheave
Two lower sheaves being arranged in juxtaposition on frame are constituted, and mutually can be rotated between upper and lower pulley yoke；The aerial earth wire is by three axle pulleys
The top sheave of group is passed through；Two lower sheaves of the assembly pulley lower parallel of extension aerial earth wire are made to pass through insulation ropes across in wire
On, insulation ropes two ends to be hung down to ground, Ground Operation personnel are using the insulation ropes hung down to ground by assembly pulley from trolley line
On slide at scissors crossing thing；
2nd, Ground Operation personnel will ask line wheel to tie up, and the support line wheel is made up of wheel body and wheel shaft with inner concave, and two
Side axle end is provided with two mutually in 90 ° and the position identical collar, and using the insulation ropes as index rope, ground is made
The two ends of a piece insulation ropes are drawn from corresponding two collars in the position of support line wheel both sides by industry personnel, by another eradication edge
The two ends of rope are drawn from corresponding another two collars in the position of support line wheel both sides, line wheel will be ask to be promoted to uniform speed
Below wire at 100mm 200mm, by conductor loop around while using temporary ground anchor by the two ends of two insulation ropeses
Tie up, when declining wire, certain height can be kept with ground, reach safe distance；
3rd, recycle insulation ropes pilot to swing, beat, prevent touching to be located on same tower bar and frame cloth
The powered side wire that puts.
The invention has the beneficial effects as follows：
1st, can arbitrarily be slid on the aerial earth wire between two bars using three axle assembly pulleys any between two shaft towers
At scissors crossing；When declining wire using the support line wheel controlled by insulation ropes, can with ground keep certain safety away from
From, make restringing and pitch certain hitch point wire when or play a part of crossing frame during unwrapping wire or stringing, it is to avoid
Crossing frame is set up at circuit scissors crossing.
2nd, avoid and set up many cumbersome process of crossing frame, it also avoid acrossing highway, high-speed railway etc. important across
Closed channel is needed more, the construction operation time is saved, while also saving many man power and materials.
3rd, this method of operating operating personnel is easy to grasp, simple to operate.
When the 4th, avoiding double-circuit line one and rewinding electricity, a thread-changing, swing because of wire, bounce easily touches powered side
Wire, causes earth fault (accident), can efficiently control swinging for wire, make job safety be protected.
5th, the method can be operated in physical features environment complex ground again, overcome because many because of factors such as physical features environment not
The construction difficult problem of crossing frame can be set up.
Save construction operation expense fund.

Specific embodiment
The step of the present invention is as follows：
1st, scheduling job personnel first are on the shaft tower needed across near, and three axle assembly pulleys are hung over built on stilts ground by rod-rising tower
On line, the three axles assembly pulley is by top sheave frame, the top sheave being arranged on top sheave frame, gliding wheel carrier and is arranged on lower sheave
Two lower sheaves being arranged in juxtaposition on frame are constituted, and mutually can be rotated between upper and lower pulley yoke, as depicted in figs. 1 and 2, described three
Axle assembly pulley includes that rectangular ring support 1, rotating shaft 2, pulley 3, bearing pin 4, baffle plate 5, closing piece 6, annular support 1 have 11 He of side plate
Base plate 12, concrete structure and Patent No. " ZL201320399382.0 " " " a kind of three axles assembly pulley " identical；Described built on stiltsly
