Vertical operation, it is larger to operating personnel's physical power loss, the livewire work time is influenced to a certain extent.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides a kind of safety, comfortable and raising operating efficiency
Multi-functional livewire work ladder head, operating personnel can be seated at operation on platform, the physical demands of operating personnel greatly reduces.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of multi-functional livewire work ladder
Head, including pulley blocks, ladder and turnover type seat, the triangular structure that the pulley blocks are made of three pulleys, the pulley
The pulley matching of group upper end is ridden on divisural line, and two pulleys matching of the pulley blocks lower end is ridden on lower divisural line, institute
The upper end for stating ladder is correspondingly connected in the downside of pulley blocks, and the ladder includes the montant on both sides and more intermediate cross bars, institute
Cross bar is stated as square pole, and the more cross bar parallel equidistants are arranged between two montants, the turnover type seat passes through two
A hinge is movably arranged on the cross bar of ladder top, and 90 ° of rotation folds can be rotated around the cross bar so that service personnel's energy
It is sitting on turnover type seat with sitting posture.
The turnover type seat includes rotary triangle stent and backrest cross bar, and two rotary triangle stents are corresponding to be connected
It is connected on hinge, the both ends of the backrest cross bar, which correspond to, to be fixed on two montants.
The backrest cross bar is located at the position of the cross bar of ladder top on the lower.
The utility model has an advantageous effect in that compared with prior art：Three pulleys are to pass through in the utility model
Side triangle mounting design.Each plane of triangle and the length that apex angle is 40cm.Just it is divisural line above and below 220kV
Distance can simultaneously fix upper and lower divisural line.Offline operation is not only convenient for, further increases stability.When operating personnel is leading
When line setting operates.Crosspiece face by hinge part can be separated, a 20cm wide is formed by 90 degree of rotation supports of triangle
Platform, operating personnel can be seated at operation on platform, the physical demands of operating personnel greatly reduces.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
In figure：1 it is pulley blocks, 2 be ladder, 21 be montant, 22 be cross bar, 3 be turnover type seat, 31 is rotary triangle branch
Frame, 32 be backrest cross bar, 4 be hinge.
Specific embodiment
As shown in Figure 1, a kind of multi-functional livewire work ladder head of the utility model, including pulley blocks 1, ladder 2 and turnover type
Seat 3, the triangular structure that the pulley blocks 1 are made of three pulleys, the pulley matching of 1 upper end of pulley blocks ride over point
It splits on line, two pulleys matching of 1 lower end of pulley blocks is ridden on lower divisural line, and the upper end of the ladder 2 is correspondingly connected with
The downside of pulley blocks 1, the ladder 2 include the montant 21 on both sides and more intermediate cross bars 22, and the cross bar 22 is square pole,
And more 22 parallel equidistants of cross bar are arranged between two montants 21, the turnover type seat 3 passes through two 4 activities of hinge
It is arranged on the cross bar 22 of 2 top of ladder, and 90 ° of rotation folds can be rotated around the cross bar 22 so that service personnel can be with seat
Appearance is sitting on turnover type seat 3.
The turnover type seat 3 includes rotary triangle stent 31 and backrest cross bar 32, two rotary triangle stents 31
It is correspondingly connected on hinge 4, the both ends of the backrest cross bar 32, which correspond to, to be fixed on two montants 21.
The backrest cross bar 32 is located at the position of the cross bar 22 of 2 top of ladder on the lower.
The utility model is as a kind of safety, livewire work ladder head that is comfortable and improving operating efficiency.Including：Three pulleys
Stent, leans against round steel at fixed transverse rod, and crosspiece pipe is changed to rectangular epoxy resin, to increase frictional force and sole forced area,
Seat apparatus will be installed additional on rectangular pedal.
The operation principle of the utility model：When in use, in 110KV electrifications and power failure operation, pulley blocks 1 is hung on and are led
It can be operated on line.220KV is charged and during power failure operation, and the upper head sheave of pulley blocks 1 is hung on upper divisural line, lower end two
Pulley is hung on lower divisural line and can operate.Original horizontal pipe, 10 centimetres wide of rectangular epoxy resin is changed to, to increase friction
Power and sole forced area.The 90 degree of rotations of stress triangular support bracket energy, the seat available for operation people of one 20 centimetres of formation
