Irregular concrete column carrying device

Abstract

The invention discloses an irregular concrete column carrying device. The irregular concrete column carrying device comprises an inner ring and an outer ring; the outer ring is fixedly installed on the periphery of the inner ring; a pressure relief device and a lifting ring are fixedly installed on the outer ring; an even number of hold-down devices are fixedly arranged at the inner side of the inner ring; and furthermore, the multiple hold-down devices are uniformly distributed in the same vertical plane at the inner side of the inner ring along the circumference. When the irregular concretecolumn carrying device in the invention is used, the multiple hold-down devices work synchronously by utilization of the same hydraulic pump; depending on change of hydraulic pressure, connecting rodsin the multiple hold-down devices stretch out in different lengths; furthermore, concrete columns having irregular section shapes are clamped tightly; furthermore, by utilization of the pressure relief device on the outer ring, instantaneous impact force can be effectively buffered when the concrete columns are unloaded or drop inadvertently; and thus, the purpose of protecting the hold-down devices and the concrete columns is achieved.

Description

technical field [0001] The invention relates to the carrying field of concrete columns, in particular to a carrying device for irregular concrete columns. Background technique [0002] The existing concrete columns are often carried by wire rings or ring rings for clamping and carrying. However, with the change of people's aesthetic standards and the diversified development of architectural styles, more and more buildings use non-cylindrical or circular lifting rings. The frequency of irregular concrete columns such as columns increases. There are certain difficulties in carrying such irregular concrete columns. The main performance is that they are easy to fall due to unstable clamping during hoisting, causing damage to the columns and threatening construction personnel. safety. Contents of the invention [0003] A carrying device for an irregular concrete column, comprising an inner ring and an outer ring fixed on the periphery of the inner ring, the outer ring is fixed...
