Embodiment 1

[0035] Please combine Figure 1-2 It should be understood that a rod lifting method includes the following steps:

[0036] S1: Set the main lifting point at one end of the rod 1, the main lifting point includes a pair of symmetrically arranged main lifting point fixing rings 2, and the first auxiliary lifting point at a distance of 1 / 4 of the length of the rod from the main lifting point. An auxiliary lifting point fixing ring 3 is set on the lifting point, and the distance from the main lifting point is 1 / 2 of the length of the rod. An auxiliary lifting point fixing ring 4 is set on the second auxiliary lifting point, and the distance from the main lifting point is 1 / 2 of the rod length Auxiliary lifting point fixing ring 5 is set on the third auxiliary lifting point at 3 / 4 of the length;

[0037] S2: Install a certain pulley 8 on the fixing ring 4 of the auxiliary lifting point;

[0038] S3: The connecting rod 11 is used to realize the connection between the main lifting r...

Embodiment 2

[0046] Other parts of this embodiment are the same as Embodiment 1, and its special feature is that the main hoisting rope 6 and the auxiliary hoisting rope 10 are all steel wire ropes.

Abstract

The invention discloses a hoisting method of a rod part. The method includes the steps of S1, setting a main hoisting point at one end of the rod part and setting a first auxiliary hoisting point, a second auxiliary hoisting point and a third auxiliary hoisting point at one fourth part, one half part and three fourths part of the length of the rod part; S2, installing a fixed pulley on the second auxiliary hoisting point; S3, connecting one end of a main hoisting rope to a hoisting device and connecting the other end of the main hoisting rope to the main hoisting point; S4, connecting one end of an auxiliary hoisting rope to a movable pulley device; S5, connecting one end of a connecting rope to the first auxiliary hoisting point and connecting the other end of the connecting rope to the third auxiliary hoisting point after the other end of the connecting rope sequentially penetrates through the movable pulley device and the fixed pulley; S6, moving the main hoisting rope and the auxiliary hoisting rope upwards by a certain height; S7, continuously moving the main hoisting rope upwards and moving the auxiliary hoisting rope downwards; and S8, stopping moving of the main hoisting rope and the auxiliary hoisting rope after the rod part is adjusted to a required position. The method has the advantage of preventing the rod part from being broken.

Description

technical field [0001] The invention relates to a method for lifting a rod. Background technique [0002] The length of the rods that need to be lifted is constantly increasing in engineering construction. For example, the steel cage needs to be connected into a 24m full section according to the design requirements for lifting. For example, a 50m steel pipe pile needs to be driven into the soil as a whole with a single length. However, after the length of the rod is increased, when the rod is changed from a horizontal state to a vertical state, it is easy to cause a safety accident that the rod is broken from the middle due to uneven force between the lifting point and the lifting point due to the weight of the rod itself; or When the component changes state, the swing range is too large, which will cause the safety accident of the lifting equipment overturning. Contents of the invention [0003] The technical problem to be solved by the present invention is the problem t...
