Description

Portable on-pole lifting device Technical Field The invention relates to the technical field of lifting, in particular to a portable lifting device on a rod. Background In the field of metal cutting and welding equipment manufacturing such as automatic semiautomatic electric arc, plasma arc welding machine, etc., the operation scene on the wire pole is very common, for example small-size equipment matched with the welding machine is installed and overhauled on the wire pole, small-size spare part and power supply part transport etc. on the wire pole, all need accomplish the lift operation of part with the help of hoisting accessory to reduce staff's intensity of labour, ensure safety and the operating efficiency of wire pole overhead operation. At present, the lifting device for the operation on the telegraph pole in the field mainly adopts the structural design of the traditional lifting device and is mainly divided into two major types of large lifting machinery and simple lifting tools. The large hoisting machine has strong hoisting capability, can meet the hoisting requirement of small equipment matched with a welding machine, is limited by the terrain condition of a telegraph pole operation site, often cannot reach an operation area smoothly, has huge equipment size and heavy weight, is extremely difficult to carry and deploy, is difficult to meet the flexible operation requirement of high altitude of a power distribution pole, and is inconvenient for workers to carry and transport due to the fact that the simple hoisting tool has relatively small size, but is mainly fixed in structure and cannot be folded or contracted for storage. Disclosure of Invention In order to solve the problems, the invention provides a lifting device on a rod, which is convenient to carry. The technical aim of the invention is achieved through the following technical scheme that the lifting device on the rod convenient to carry comprises two fixing seats, a transverse hanging rod, an inclined hanging rod, a wheel shaft and a hanging wheel, wherein one end of the inclined hanging rod is rotatably connected with one fixing seat, the other end of the inclined hanging rod is rotatably connected with the wheel shaft, one end of the transverse hanging rod is rotatably connected with the other fixing seat, the other end of the transverse hanging rod is rotatably connected with the wheel shaft, the hanging wheel is rotatably connected with the wheel shaft, and a locking assembly which relatively fixes the two fixing seats when in a storage state is arranged on one fixing seat. Through adopting above-mentioned technical scheme, through setting up the basic support that two fixing bases were the device, correspond on two fixing bases respectively and set up the core function that the operation was lifted by crane in the support realization of horizontal jib, shaft cooperation hanging wheel and oblique jib, but horizontal jib, the rotation angle of adjusting device is connected with the rotation of shaft to the jib, the adaptation accomodates scene and working scene demand, locking assembly can be with two fixing bases relatively fixed under the device accomodates the state simultaneously, effectively reduce the volume after accomodating, hoisting device's portability, the staff of being convenient for carries to the pole on-the-spot operation, the reduction transport degree of difficulty.
