Abstract
A hoisting tool for the maintenance of an electric power line comprises a base, a support rod and a suspension arm, wherein one end of the suspension arm is arranged at the upper end of the support rod by an angular contact bearing, the other end of the suspension arm is fixedly provided with a fixed pulley; a pulling rope is wound on the fixed pulley, one end of the pulling role drops vertically, a lifting hook is fixedly arranged at the lower end of the pulling rope, and the other end of the pulling rope bypasses a roller wheel on the suspension arm and is wound and connected on a ratchet wheel fixed on the base; and the ratchet wheel and a pawl on the base form a one-way rotating mechanism, the pawl is arranged on the base by a rotating shaft, a spring is arranged between the pawl and the base, and a handle is arranged on the ratchet wheel. The hoisting tool for the maintenance of the electric power line is provided with the support rod and the suspension arm, the fixed pulley is arranged on the suspension arm, the pulling rope is wound on the fixed pulley, a power device can be hoisted conveniently by rotating the handle, the suspension arm can rotate around a bearing at on one end of the suspension arm, so that the adjustment is convenient; and the other end of the pulling rope is wound on the ratchet wheel which can only rotate in the single direction, so that a device can be prevented from slipping downwards in the hoisting process, and the position of the device can be fixed at any time.
Description
Technical field
The utility model relates to electric power transmission line maintenance auxiliary device, specifically is a kind of lifting device of electric power circuit maintenance.
Background technology
When electric power circuit maintenance and upgrading, to change or increase some complete equipments by needs, the quality of these complete equipments is bigger, and these equipment just can give rise to certain altitude by the needs lifting device.Because electrical equipment and substation etc. are subjected to the restriction of geographical space, can not make the on-the-spot lifting vehicle that uses, therefore many by these equipment of artificial lifting, this causes inefficiency, make that the electric power circuit maintenance time is long, influence the power supply of electric power circuit, and adopt artificial lifting, poor stability is adjusted the position when being not easy to install in artificial lifting process.
Summary of the invention
The purpose of this utility model is to provide a kind of lifting device of electric power circuit maintenance, and the lifting device of described this electric power circuit maintenance will solve the equipment that quality is bigger in the electric power maintenance process in the prior art to be needed artificial lifting to cause inefficiency, inconvenient technical matters is installed.
The purpose of this utility model is achieved through the following technical solutions: comprise base, strut bar and arm, arm one end is located at post upper by angular contact bearing, the arm other end is fixed with fixed pulley, on this fixed pulley, be wound with stay cord, sagging and its lower end of stay cord one end is fixed with suspension hook, the stay cord other end is walked around the roller on the arm and is wire-wrapped on the ratchet that is fixed on the base, this ratchet be located on the base ratchet and constitute unidirectional rotation mechanism, ratchet is located on the base by rotating shaft, be provided with spring between ratchet and the base, on ratchet, also be provided with handle.
Arm and strut bar are provided with hold-down arm, establish bearing between hold-down arm and the strut bar.
Be provided with lock bolt between the arm other end and the strut bar.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with strut bar and arm in the lifting device of electric power circuit maintenance, arm is provided with fixed pulley, fixed pulley is wound with stay cord, by turning handle, can lift by crane electrical equipment easily, and this arm can rotate around the bearing of one end, convenient easy to adjust, the stay cord other end is around on the ratchet, and ratchet can only unidirectional rotation, avoid the unexpected downslide of equipment in the lifting process, the while is the fixed position at any time.
