Technical field
The utility model relates to a kind of climb type rope ladder, particularly a kind of between overhead power transmission line pole tower cross-arm and wire high-altitude climb operation, take into account the instrument of the secondary protection function of wire dropping when preventing upkeep operation.
Background technology
At present, the main tool of climbing up and down between overhead power transmission line pole tower cross-arm and wire is aluminium alloy hanging ladder, this instrument self is heavier, operation at least needs two people under shaft tower, fit through the upper and lower tool for transmitting of electrodeless rope at the scene, and aluminium alloy hanging ladder upper end is suspended on cross arm of tower, lower end cannot be fixed, work high above the ground personnel swing back and forth when upper and lower aluminium alloy hanging ladder, especially have a power failure and change in composite insulation subjob, the specific purpose tool preventing the second protection of wire dropping must be hung before operation, for keeping Equilibrium to trample insulator sometimes when the upper and lower aluminium alloy hanging ladder of work high above the ground personnel and upkeep operation, during operation, work high above the ground personnel should keep Equilibrium, also to overhaul in high-altitude, check and accept operation, work high above the ground personnel labor intensity and operating risk larger.
Summary of the invention
The purpose of this utility model solves between overhead power transmission line pole tower cross-arm and wire to climb a work high above the ground difficult problem of easily trampling suspension type synthetic insulator up and down; a kind of climb type steel cable ladder of work high above the ground between overhead power transmission line pole tower cross-arm and wire is provided; easy operation, to be easy to carry; practicality is flexible and field work safe is reliable; can one man operation; have the secondary protection function preventing wire dropping concurrently; reduce work high above the ground labour intensity and the operating risk of operating personnel on tower, increase work efficiency.
Of the present utility model being characterised in that comprises: several stirrup formula pedal, rope ladder main rope and wire hooks, described stirrup formula pedal comprises pedal steel wire loop, be plugged on rope ladder main rope by the upper end steel wire rope of pedal steel wire loop, pedal steel wire loop is fixed on rope ladder main rope, the two ends of rope ladder main rope are plugged with upper end steel wire loop, lower end steel wire loop respectively, on the steel wire loop of upper end, cover has upper U-shaped ring, and lower end steel wire loop is connected with wire hook by lower U-shaped ring.
Described pedal steel wire loop is fastened on rope ladder main rope by iron tied silk.
The pedal steel wire loop of described stirrup formula pedal is installed with pedal tube, and pedal tube two ends respectively have a sulculus.
Described pedal tube cross section is circular or square.
Rope ladder main rope from upper end to lower end every the 40cm distance even grafting in left and right stirrup formula pedal.
With having the movable sealing of transferring unlocking function on described wire hook.
As mentioned above, the utility model is the intensity of the steel wire loop ensured on rope ladder main rope and stirrup formula pedal, selection adopts steel wire rope, Joining Technology all adopts steel wire rope inserting mode connect; For solving the shaft tower being applicable to different types, rope ladder main rope upper end steel wire loop is connected with cross arm of tower by upper U-shaped ring; Swinging for reducing the upper and lower rope ladder of operating personnel, adding wire hook in rope ladder main rope lower end; For being applicable to different height operating personnel climbing, at rope ladder main rope from upper end to lower end every the 40cm distance even grafting in left and right stirrup formula pedal; Swing for preventing stirrup formula pedal and be convenient to operating personnel and directly pin is put into stirrup formula pedal, adopt iron tied silk to be fixed on rope ladder main rope by stirrup formula pedal; For reducing the injury of foot's extruding when stirrup formula pedal steel wire loop is climbed operating personnel, the foot-operated steel wire loop of stirrup formula pedal installs pedal tube additional; For preventing the pedal tube of stirrup formula pedal from rolling when trampling, respectively have a sulculus at the same tangent plane two ends of pedal tube pipe; For ease of regulating wire hook direction when installing cat ladder, U-shaped ring is adopted to connect wire hook and rope ladder main rope lower end steel wire loop; For preventing the wire dropping when upkeep operation, the wire hook with having movable sealing is adopted to carry out second protection; In order to be convenient to take off wire hook when the end of job, adopt the wire hook with the movable sealing of the function transferring unblock.
Operation principle of the present utility model: rope ladder main rope upper end steel wire loop is connected with cross arm of tower by upper U-shaped ring; the wire hook that rope ladder main rope lower end steel wire loop connects hangs on wire; work high above the ground personnel grab rope ladder main rope by left and right equally distributed stirrup formula pedal and hand on foot-operated rope ladder main rope; realize high-altitude between overhead power transmission line pole tower cross-arm and wire climb rope ladder or stand in rope ladder carries out overhaul, the work high above the ground such as examination; and play second protection effect when changing insulator or gold utensil, effectively prevent wire dropping.
The beneficial effects of the utility model: solve the work high above the ground problem of to climb difficulty between overhead power transmission line pole tower cross-arm and wire up and down, especially suspension type synthetic insulator be connected gold utensil operations such as changing synthetic insulator of overhauling, check and accept and have a power failure between wire and climb up and down and easily trample a suspension type synthetic insulator difficult problem; Through field test repeatedly with improve and optimizate proof; restriction not by overhead power transmission line pole tower pattern when this climb type steel cable ladder uses; easy operation, to be easy to carry; practicality is flexible and field work safe is reliable, can carry out one man operation, have the secondary protection function preventing wire dropping concurrently; reduce operating personnel's workload on tower; reduce work high above the ground labour intensity and the operating risk of operating personnel on tower, increase work efficiency, save field operation cost.
