According to the technical solution of the utility model: a kind of windproof drag-line with ratchet device, comprise upper binding head, drag-line body and lower union joint, described upper binding head and described lower union joint are equipped with the ratchet device that rotates described drag-line body respectively by the opposite two ends that are threaded in described drag-line body of rotation direction on the described drag-line body; Described ratchet device comprises and is fixed on the support on the described drag-line body and is installed in handle on the described support, the left tooth papillae wheel and the right tooth papillae wheel that are fixed on the described drag-line body are installed on the described support, two ratchets also are installed on the described support, and described two ratchets are meshed with described left tooth papillae wheel and described right tooth papillae wheel respectively under the control of control mechanism.
Described left tooth papillae wheel and described right tooth papillae wheel are connected on the described drag-line body by key.
Described support comprises upper bracket and lower bracket, described left tooth papillae wheel, described right tooth papillae wheel and described two ratchets are between described upper bracket and described lower bracket, described two ratchets are installed on the ratchet anchor shaft, and described ratchet anchor shaft is parallel to the axis of described drag-line body.
Described handle is hinged on the described upper bracket by jointed shaft, and is positioned on the described upper bracket by bearing pin.
Have two knock holees that match with described bearing pin on the described upper bracket, the line between described two knock holees and the described jointed shaft is perpendicular.
Described control mechanism comprises the control stalk that is fixed on described ratchet anchor shaft one end, is fixed with spring between the free end of described control stalk and the described upper bracket.
Described upper binding head is the open type screw rod, and described lower union joint is the enclosed screw rod.
Technique effect of the present utility model is: the utility model is provided with ratchet device at the body of windproof drag-line, only uses a handle, and needed operational space is little, operates lightly, can satisfy well site operation personnel's use.
