Description

Steel bar hoisting and clamping device for building engineering

Technical Field

The utility model relates to a lifting device technical field, specific theory especially relates to a reinforcing bar hoist and mount clamping device for building engineering.

Background

Generally, reinforcing steel bar products such as deformed steel bars and small-sized bars are packaged in bundles in a fixed-length state of 9 meters or 11 meters, and the weight of the reinforcing steel bar products is about 2 tons according to the standard requirements of products. In order to save the occupied space, batch products are generally placed in a pile, and are also placed in a pile in the material transportation process, so that great inconvenience is caused in the lifting process. At present, a steel wire rope is mainly used for hoisting, two-point or multi-point force bearing is adopted due to the fact that the steel bars are long, if pre-arranged objects such as partition plates are arranged between one pile and the other pile in the process of placing the steel bars in advance, the steel wire rope threading and bundling are facilitated, but the pre-arranged objects are not arranged under most conditions, a hoisting worker can only lift one end of a bundled product and then place the pre-arranged objects to re-bundle the steel wire rope, the other end of each steel bar is also operated in the same mode, the process operation is complex, and the hoisting efficiency is low. At present, still there is a round steel hoist on the market, is used for hoisting round steel and steel ingot specially, and it adopts lever theory of operation to be similar to the scissors, and there is the lifting hook in its upper portion, and clamping device is for opening and shutting in the lower part, and the middle part is rhombus connecting rod power transmission structure, and clamping device opens when needing the handling round steel, arranges the top that needs the centre gripping round steel in, and the jack-up machinery lifts by crane, along with the rising of lifting hook, tightens up clamping device's jack catch through power transmission mechanism, reaches and ties up the effect to accomplish the handling. However, this embodiment is based on the premise that the jaws must be positioned above the radius of the round bar before clamping, in order to ensure that the round bar is clamped and prevented from slipping off. Lifting by crane can adopt this round steel hoist to single bundle of screw-thread steel, nevertheless the jack catch is difficult to be wrapped up whole bundle of reinforcing bar when piling up reinforcing bar products such as the screw-thread steel that is in the same place for bundling, consequently, directly adopt the unable handling of round steel hoist to pile up bundled reinforcing bar together, and current hoisting device, its clamping device's below is open, if the accident appears, the reinforcing bar will drop, the security is low, traditional hoisting device structure is unstable in addition, when lifting by crane, rocks easily.
