Clamp control method for unequal-diameter long rod

Abstract

The invention discloses a clamp control method for an unequal-diameter long rod. The clamp control method comprises the following steps that 1) a clamp controls gripping clamp sets of at least two gripping clamp units to be completely expanded through combined actions of all gripping clamp oil cylinders of the at least two gripping clamp units; 2) the clamp can do a gesture capable of fully holding the unequal-diameter long rod; and 3) the clamp controls all gripping clamp sets of the at least two gripping clamp units to do at least two kinds of unequal amplitude linkage closing through reverse combined actions of all gripping clamp oil cylinders of the at least two gripping clamp units so that the action of clamping at least two parts, with the at least two unequal rod diameter values, ofthe unequal-diameter long rod can be done; and the gripping clamp sets corresponding to the at least two unequal rod diameter values are closed to be in place according to the sequence from the largerod diameter value to the small rod diameter value to clamp the corresponding parts of the unequal-diameter long rod. According to the scheme, simple, stable and reliable tightening and clamping operation on the unequal-diameter long rod is achieved, various complicated construction operation such as displacement and rotation possibly caused successively is better facilitated, the practicabilityis high, and the caused economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of clamp control, in particular to a clamp control method for unequal-diameter long rods. Background technique [0002] At present, in many construction operations, operations such as displacement and installation of long rods with a long length (such as more than 10 meters) need to be carried out, and clamps are usually used to implement. When the long rod is a regular equidiameter (rod diameter) structure, existing common various clamps can be used. However, when the long rod is of unequal diameter structure, ordinary clamps are obviously unable to clamp it stably, let alone perform various installation operations such as displacement and rotation. [0003] Such as, when electric power construction is erecting utility pole at present, all is to adopt crane to bind utility pole with rope, lifts again, and utility pole is installed. However, the cost of the crane shift is very high, and the function is sin...

AI Technical Summary

Problems solved by technology

When using ordinary clamps to clamp the utility poles, the clamps must hold the utility poles tightly, and the contact surface between the clamps and the utility poles must have a certain span. There is a certain difference in the diameter of the long rods with unequal diameters in this span. The clamping jaws are of equal width and clamping distance, acting on utility poles with unequal diameters, and cannot achieve complete clamping effect. In actual operation, it is necessary to repeatedly try to select a suitable position for clamping, and the clamping is very weak and unstable, which is difficult When performing operations such as rotation and erection, there is a high probability of failure due to operational errors, which brings great inconvenience to construction operations
