A kind of fixture control method for unequal diameter long rod

Abstract

The invention discloses a clamp control method for long rods with unequal diameters. The steps are as follows: 1) The clamp controls the clamping groups of the at least two clamping units to fully open through the combined action of the clamping oil cylinders of at least two clamping units. ; 2) the clamp can fully embrace the posture of the unequal-diameter long rod; 3) the clamp controls the clamping groups of at least two clamping units to perform at least Two kinds of unequal-amplitude linkage closures are used to clamp at least two parts of the unequal-diameter long rod with at least two unequal rod diameter values; the at least two unequal rod diameter values ​​vary from In order from large to small, the corresponding gripper groups are closed in sequence to clamp the corresponding parts of long rods with unequal diameters. This case realizes simple, stable and reliable clamping and clamping operations for unequal-diameter long rods, and is very conducive to subsequent possible complex construction operations such as shifting and rotation. It is extremely practical and brings high economic benefits.

Description

technical field [0001] The invention relates to the technical field of clamp control, in particular to a clamp control method for long rods with unequal diameters. Background technique [0002] At present, in many construction operations, operations such as displacement and installation of long rods with a long length (for example, more than 10 meters) are required, and clamps are usually used for implementation. When the long rod has a regular equal diameter (rod diameter) structure, various existing common clamps can be used. And when the long rod is of unequal diameter structure, it is obvious that ordinary clamps cannot 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 is very high, and the function is si...

AI Technical Summary

Problems solved by technology

When ordinary clamps are used to clamp the utility poles, the clamps must hold the utility poles tightly. 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. Each of the common clamps 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
