With the increase of national railway construction tasks, the task of erecting high-speed rail bridges is becoming more and more arduous. Therefore, the number of traditional 450T gantry cranes used to load beams for beam trucks is also increasing. However, 450T gantry cranes are expensive, and the installation and disassembly procedures are complicated and risky. Big.

When erecting the high-speed rail box girder, a 450T girder gantry crane is required to load the girder to the girder truck in advance, and then transport the girder to the bridge erecting machine to start erection.

The traditional construction method is mainly 1 set (2 sets) of 450T gantry cranes to lift the hoisting holes at both ends of the box girder to load the girders to the waiting girder trucks below.

The main disadvantages of this construction method are that the equipment is expensive, the operation takes a long time to lift, and human factors are large. During the construction process, the installation of beams depends on the proficiency of the operator; the cost of equipment maintenance is high, and the installation and disassembly process of equipment transfer is complicated. High security risk.

The side of the concrete cap is trapezoidal, and this shape can improve the supporting capacity, effectively support the pressure on the top, and can disperse the pressure on the top.

A plurality of rubber plates are arranged on the upper cover plate, and the rubber plates play the role of protection and shock absorption, and prevent the concrete box girder from being damaged due to hard contact with the steel box girder of the temporary storage beam support.

The rubber sheet is composed of a rubber sheet vertical partition and a rubber sheet transverse partition to form a square structure, which is used to fix the rubber sheet to prevent it from slipping.

The bottom of the lower cover plate is provided with a plurality of chutes in parallel, and the chutes play a guiding role. When the concrete box girder is lifted by the beam lifting cylinder, the temporary storage beam support is conveniently withdrawn.

The upper and lower cover plates and the web are connected to form an integrated structure, and lifting lugs are arranged symmetrically on both sides, which is conducive to lifting stability and convenient lifting.

There are two rows of lifting lugs on each side corresponding to the upper and lower sides, which can meet different lifting requirements and increase work flexibility.

When the utility model is used, it is divided into the following steps:

The first step is to place the temporary storage beam support according to the concrete cap;

In the second step, the beam lifting machine places the concrete box girder on the temporary storage beam support;

The third step is that the beam transport vehicle enters under the temporary storage beam support in the low position state;

In the fourth step, the beam transporter hangs the oil cylinder for lifting action, and the beam transporter carries the load;

The fifth step is to raise the jacking oil cylinder, and the temporary beam storage bracket is dragged out by drag chain and removed by crane or other equipment;

The oil cylinder of the sixth beam transporting vehicle shrinks, reducing the height of the concrete box girder and driving out of the beam field;

The seventh step is to use a crane or other equipment to place the temporary beam storage bracket on the top of the concrete cap for the next step of box girder hoisting.

The beneficial effects of the utility model are:

(1) The installation of the beam is easy to operate, the safety risk of the installation and disassembly of the bracket is low, it is simple and fast, the quality requirements of the operators are not high, and the maintenance is simple and convenient.

(2) The economic effect is good. Compared with the traditional construction technology, a set of 450T girder gantry crane can save 12 million yuan in funds, and can save 2.6 million yuan in transportation and installation and disassembly costs.

(3) High work efficiency. Traditional construction requires 12 workers for each set of equipment, but now only 4 people are needed in the beam transporting lathe team to solve the problem of beam storage.
