Description

A component for hoisting a steel cage

technical field

The invention relates to a component used for hoisting a relatively long reinforcement cage in bridge pile foundation construction, and belongs to the field of hoisting construction. the

Background technique

In pile foundation construction, in order to hoist the reinforcement cage and install the reinforcement cage in the borehole, the method of hoisting by crane is usually used. According to the conventional method, two cranes are generally used for the longer reinforcement cage. During construction, one crane (main crane) is used at the front and middle of the reinforcement cage, and another crane (auxiliary crane) is used to hoist the tail of the reinforcement cage. The two cranes cooperate with each other. The crane cooperates to make the reinforcement cage leave the ground, and the auxiliary crane adjusts the reinforcement cage by adjusting the height of the lifting rope until the reinforcement cage is vertical. Thereby adopting this method requires a large amount of mechanical usage, requires two cranes, takes a long time, and requires high technical requirements for the mechanical operator. the

Utility model content

In order to overcome the above problems, the present invention proposes to use a new type of component, which can improve and save the use of machinery, personnel and time under the original construction conditions to the greatest extent, and has a relatively simple structure, low requirements on objective conditions, and is suitable for wide use . the

Its specific technical scheme is as follows:

A component for hoisting a reinforcement cage, which includes a shoulder pole beam, a steel wire rope, a hook and a fixed pulley 1, and a crane main hook hoisting hole 2 for connecting with the main hook of a crane is opened at the center of the shoulder pole beam. There are pulley installation holes 3 on both sides of the hook hoisting hole 2, and a fixed pulley 1 is installed on the pulley installation hole 3, and the wire rope bypasses the fixed pulley 1 to connect with the steel cage to be hoisted; the fixed pulley 1 is installed in the pulley installation hole through the hook 3; between the fixed pulley 1 and the hook and between the fixed pulley 1 is a collar, the hook and the hook installed in the hoisting hole 2 of the main hook of the crane can rotate freely, and the steel wire rope can slide freely in the fixed pulley 1. the

The diameter of the wire rope used is 16mm. the

The material of the fixed pulley 1 is not lower than A3 steel, and the thickness of the steel plate selected for the pole beam is 10mm. the

The maximum distance between the pulley installation holes 3 on both sides of the pole beam is slightly larger than the diameter of the reinforcement cage to be hoisted. the

The manufacture method of the present utility model is as follows:

First of all, use a steel plate with a thickness of 10mm to make a pole beam for the components according to the use requirements, install the fixed pulley components at both ends of the pole beam, and check that its safety meets the requirements. Install the wire rope on the fixed pulley, fix the two ends of the wire rope on the upper and middle parts of the reinforcement cage with a saber buckle, and then install the wire rope of the small hook of the crane on the tail of the reinforcement cage. the

The use process of the utility model is as follows:

When hoisting, first use the small hook to lift the lower part of the steel cage so that it is about to leave the ground, and then lift the large hook so that the upper part of the steel cage is 60° from the ground. Then raise the small hook to make the whole reinforcement cage suspended from the ground, turn the long arm of the crane, adjust the verticality of the reinforcement cage at the drilling position, and lower the small hook so that the reinforcement cage and the drilling hole are basically vertical. Finally, use the fixed pulley of the device to adjust the angle of the reinforcement cage during the vertical process, and remove the small hook after it is completely vertical to the drilled hole, so that the reinforcement cage is completely lifted by the large hook, and the hoisting before the reinforcement cage enters the hole is completed. the

The utility model can obtain the following beneficial effects:

The utility model uses the "shoulder pole beam" and the fixed pulley method to use only one crane, which reduces the construction area during construction, saves construction time and mechanical costs, and improves work efficiency. the

Detailed ways

Below in conjunction with accompanying drawing the utility model is described in detail:

As shown in Figures 1 to 3, a member for hoisting a reinforcement cage includes a pole beam, a steel wire rope, a hook and a fixed pulley 1, and is characterized in that a main hook for connecting with a crane is provided at the center of the pole beam The connected hoisting hole 2 of the main hook of the crane has a pulley installation hole 3 on both sides of the hoisting hole 2 of the main hook of the crane. The fixed pulley is installed on the pulley installation hole 3, and the wire rope bypasses the fixed pulley 1 and the reinforcement cage to be hoisted. connection; the fixed pulley 1 is installed in the pulley installation hole 3 through a hook; the ring between the fixed pulley 1 and the hook hook and the fixed pulley 1 is a ring, and the hook and the hook installed in the hoisting hole 2 of the main hook of the crane can be freely Rotate, steel wire rope can slide freely in fixed pulley 1. the

The diameter of the wire rope used is 16mm. the

The material of the fixed pulley 1 is not lower than A3 steel, and the thickness of the steel plate selected for the pole beam is 10mm. the

The maximum distance between the pulley installation holes 3 on both sides of the pole beam is slightly larger than the diameter of the reinforcement cage to be hoisted. the

The member of hoisting reinforcement cage of the present invention is applied in practice:

After the reinforcement cage is manufactured, it is transported to the site. First, install the "horse pole beam" on the hook of the crane, and install the components on the appropriate pulley installation holes according to the size of the hoisting reinforcement cage. Bind the steel wire ropes used for hoisting to the upper and middle parts of the reinforcement cage respectively through fixed pulleys. Then install the small hook wire rope at the end of the reinforcement cage. the

During the hoisting process, firstly lift the small hook so that the lower part of the steel cage is about to leave the ground, then lift the big hook to lift the upper part, and ensure the stability of the steel cage through the adjustment of the fixed pulley. At 60°, lift the small hook to make the steel cage off the ground. After the reinforcement cage is raised to the point where the formed hole is basically vertical, slowly lower the small hook to keep the reinforcement cage vertical. At this time, the distance between the shoulder pole beam and the top of the reinforcement cage is 40cm-60cm, and the small hook wire rope can be removed. the

Using this method to transport the steel cage can effectively shorten the time. Only one crane is used, which greatly improves the economic benefits and effectively completes the hoisting of the steel cage. And the operation is relatively simple. the

To sum up, the construction method of hoisting steel cages with this new type of components not only saves construction time, but also has the characteristics of good operability and economy, and has high promotion and application value. the
