Description
Technical Field
The utility model relates to the technical field of engineering machinery, in particular to a steel reinforcement cage lifting appliance and a crane.
Background
In the construction process of the underground diaphragm wall, an integral manufacturing and one-time lifting and slot-entering construction method is generally adopted for the wall steel reinforcement cage. As shown in fig. 1, the steel reinforcement cage 1 is lifted by a lifting appliance 2 comprising a hook, a shoulder pole, a wire rope and the like, and the overall height of the lifting appliance 2 is generally about 3.5m.
When the construction site is affected by the obstacle 3 and can only work below the height limiting area 4, the site hoisting height is insufficient, the method of manufacturing the reinforcement cage 1 in a segmented mode is adopted, and the segmented reinforcement cage 1 is connected in a welding mode and the like during hoisting, so that the integrity of the continuous wall reinforcement is ensured.
The traditional construction method for sectionally hoisting the reinforcement cage 1 in the operation below the height limiting area 4 comprises the following steps: the adoption of a crane to segment the reinforcement cage 1 into the groove shortens the manufacturable length of the reinforcement cage 1 once again under the condition of limited hoisting height, but the problems of the following two points are caused:
(1) The hoisting times are more, the welding lengthening times are more, the time and the labor are consumed, the cost is increased, and the integrity of the reinforcement cage 1 is poor;
(2) The time for placing the reinforcement cage 1 is increased, the time for exposing the groove wall is increased, the phenomena of groove wall collapse, cage body mud clamping, excessive sediment and the like are easily caused, and the control of the construction quality of the underground diaphragm wall is unfavorable.
For example, in the construction of a certain project underground continuous wall, a high-voltage wire at a wall position is 11m high above the ground, according to the standard requirement, the hoisting operation under the high-voltage wire needs to ensure a safe distance of 5m, and the traditional sectional hoisting operation hoist 2 occupies a space of 3.5m, so that the sectional length of the manufacturable reinforcement cage 1 is only 2.5m theoretically.
