Utility model content
The utility model technical issues that need to address be to provide a kind of be applied in transmission line for use when the brushing insulator string simple in structure, portably use conveniently and lightweight special stand, guaranteeing, on the basis of operating personnel's safety, to improve brushing quality and painting efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
In transmission line for the special stand of brushing insulator string, comprise strip angle type base, the horizontal supporting plate that described angle type base is fixedly connected with by side and vertically supporting bracket form, the two ends of angle type base connect a hook arranging perpendicular to angle type base horizontal supporting plate by connector respectively, position near hook lower end on the upper surface at described horizontal supporting plate two ends is fixedly connected with respectively a link, and between two links, bolt is useful on the insulating cord of pilot angle type base balance.
The concrete structure of described connector is: connector comprises two braces that are symmetricly set on both sides, vertical supporting bracket front and back, between two braces, by bolt, is fixedly connected with vertical supporting bracket; Between two braces, be also bolted a Connection Block that is positioned at angle type base top, the bottom of described hook is hinged in the groove of Connection Block by bearing pin.
Improvement of the present utility model is: described angle type base consists of the hinged base unit of rotating disk by two, and the horizontal supporting plate that described each base unit is fixed together by one group of side and vertically supporting bracket form.
Further improvement of the utility model is: described angle type base adopts epoxy resin board to make.
Owing to having adopted technique scheme, the obtained technological progress of the utility model is:
The utility model is simple in structure, carry and easy to use, and with respect to the flat ladder of traditional metal, small volume, weight are lighter, and are easy to before use be arranged on transmission line and shaft tower; As adopt the flat ladder of traditional metal to be coated with silica gel operation, and change the activity duration average out to 29 minutes of every insulator string, and adopt the utility model only to need to fulfil assignment for 15 minutes, greatly improved operating efficiency.
The utility model adopts angle type base, can strengthen bearing capacity of the present utility model and intensity, effectively guarantees operating personnel's safety.The insulating cord that angle type base arranges by link, be used in installation process, utilize insulating cord pull-up angle type base, make angle type base leave insulator string certain angle, make the utility model when operation, be positioned at the side-lower of transmission line, convenient working personnel operation, and can guarantee that the utility model can not rock back and forth in operation process, improves stability of the present utility model and staff's fail safe.
Between angle of the present utility model type base and hook, adopt articulated manner, can make hook bend when not using, angle type base is assembled by two groups of base units so that when not using by rotating disk by its doubling, the volume when reducing the utility model and carrying.Angle type base adopts epoxy resin board to make, and can greatly alleviate weight of the present utility model, and convenient working personnel carry.
