[0013] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The technical scheme of the utility model will be further described below with reference to the drawings of the utility model embodiments. The utility model is not limited to the following specific embodiments.

[0014] It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top" and "bottom" is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore, the terms describing the position relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation on the patent. For ordinary skilled persons in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0015] In one embodiment, as shown in Figure 1 , Figure 2 A lifting rod, comprising an insulating pipe 1, the bottom of the insulating pipe 1 is provided with a hand knob 2, the bottom of the hand knob 2 is provided with two pull wires 3, the bottom of the two pull wires 3 is commonly provided with a wire ring 4, the left side of the insulating pipe 1 is provided with two wind rope pull wires 5, the bottom end of the two wind rope pull wires 5 is commonly provided with a line tightener 6, the outer edge of the insulating pipe 1 near the bottom is provided with a plurality of supporting legs 8, the outer edge of the insulating pipe 1 is provided with a winch lifting device 7, the bottom of the line tightener 6 and the plurality of supporting legs 8 is provided with an expansion screw 9, and the insulating pipe 1 is made of high-strength aluminum alloy profile.

[0016] The lifting rod is compact in structure and is composed of a lifting rod, supporting legs 8, a winch lifting device 7, a pull wire system and the like. The winch lifting device 7 transmits power through a steel wire rope combination to achieve the purpose of lifting. A "double extension mechanism" is adopted, that is, each section of movable rod is lifted at the same time, the speed is fast, the steel wire rope is exposed after being lifted, and the rod can be self-locked at any height position and cannot slide downward. The built-in pulley and the steel wire rope are reasonably arranged in the limited space between the rods.

[0017] The pipe material interface of the lifting rod adopts a circular cross section because the inner wall of the rod needs to be installed with a pulley and a suitable installation surface is needed. The circular anti-bending cross section coefficient of the pipe material with the same wall thickness and cross section area is large.

[0018] The winding form between the steel wire rope of the lifting rod and the rod body, the installation plane of the driving steel wire rope is in the middle plane of the rod, the installation plane of the driven steel wire rope is in the middle plane of the rod and is perpendicular to the installation plane of the driving steel wire rope, this form can avoid the collision of the two steel wire ropes in the same plane;

[0019] The key of the pulley installation is to reduce the friction, the friction force generated when the steel wire rope rolls on the pulley is actually existent, if the design consideration step, the friction force is great, directly affects whether each level rod and the thickness of the steel wire rope can be lifted, so the rolling bearing is installed in the pulley during the design.

[0020] Working principle: the lifting rod is placed vertically on the flat and solid ground, the hand screw screws on the triangular supporting legs of the lifting rod are loosened in turn, the supporting legs 8 are pulled out and stretched to the ground, the verticality of the lifting rod is adjusted through the supporting legs 8, and the bottom plates of the supporting legs 8 are pressed against the ground, the three supporting legs 8 must support the force, then the hand screw screws are tightened, the bottom plate of the lifting rod and the bottom plate of the tripod supporting leg 8 have a reserved hole, which can be fixed through a pre-buried part, a ground nail, an expansion screw 9 or a heavy object, it must be ensured that the rod body does not shake after contacting the ground, then the operation continues, the tightener is released, the winch lifting device 7 is installed on the lifting rod, the assembly is installed at the top end of the lifting rod, if there is a guide wire ring 4, the used pull wire 3 is passed through the guide wire ring 4 on the lifting rod and installed on the assembly, the winch lifting device 7 is operated to slowly lift the lifting rod, pay attention to stretch the used pull wire 3, the lifting rod is installed with a wind rope pull wire ring at the pipe wall according to the height of the expansion, according to the length of the wind rope pull wire 5, it is respectively hung on the pull wire hole, the orientation of the lifting rod pull wire hole is adjusted, a fixed point is set on the ground at a corresponding distance from the center of the lifting rod, the other end of the pull wire is connected, the lifting rod is tightened and locked after reaching the specified height, the pull wire 3 is released during the lifting process, and a designated person observes the verticality of the lifting rod, adjusts or tightens the pull wire 3 according to the needs to keep the lifting rod vertical, when the red "stop line" word at the lower part of the second meter number is seen, the lifting rod has reached the maximum height, the lifting rod is lifted to the specified position, enters the normal work, after the work is finished, the lifting rod is slowly lowered, the cable is reeled in at the same time, after the lowering is finished, the first section of the lifting rod is manually pressed down slowly, the tightener locks the first section and the last section of the lifting rod, the winch lifting device 7 is removed, the lifting rod is retracted and placed in other positions.

[0021] The technical features of the above-described embodiments can be combined in any manner, and to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
