Description

Technical Field

[0001] The utility model relates to the technical field of box beam prefabrication and transportation, and more specifically, to a multifunctional beam transport vehicle integrating prefabrication and transportation. Background Art

[0002] The transportation and erection of box girders is a key step in railway bridge construction. Traditional beam transporters are designed to transport box girders prefabricated in beam yards to bridge construction sites. These beam transporters usually have strong load-bearing capacity and stability to ensure the safety of box girders during long-distance transportation. Such beam transporters have been widely used in the field of railway bridge construction for many years, providing solid infrastructure support for railway bridge construction. However, the traditional beam transportation method has problems such as low construction efficiency, single function, and poor safety when transporting the bridge deck of reinforced concrete beam bridge to the bridge erection machine, which cannot meet the needs of large-scale construction sites. Therefore, it is very necessary to study a prefabrication and transportation integrated beam transport vehicle to overcome the following shortcomings of the traditional beam transportation method in the current railway bridge construction: 1) It is necessary to prefabricate the box beam in the beam yard and then transport it to the bridge construction site. This process is not only time-consuming, but also has high requirements on the transportation route and conditions; 2) During the transportation and erection of the prefabricated box beam, the box beam may be damaged due to multiple handling and adjustments, which increases the construction risk and cost; 3) This method is not flexible enough in engineering scheduling, especially in emergency or special circumstances; 4) Due to the single function of the traditional beam transportation method, it can only transport the box beam and cannot perform other tasks at the same time; during construction, multiple tasks may need to be carried out at the same time, such as cast-in-place, prefabrication, transportation, etc. The traditional beam transportation method with a single function cannot be competent for these tasks at the same time, which may lead to limited construction efficiency.

[0010] The utility model at least has the following beneficial effects:

[0011] The utility model provides a multifunctional beam transport vehicle for prefabrication and transportation, which can directly prefabricate box beams on the vehicle, so that the beams can be used immediately after arriving at the construction site, greatly shortening the time from manufacturing to installation, and is not limited by the transportation route and condition requirements from the prefabrication beam site to the erection site; since the number of times of handling and transportation of the beams is reduced, the transportation and handling costs, storage and custody costs, and the risk of damage to the box beams during transportation and the construction safety risks are significantly reduced; the utility model has stronger adaptability to the construction site, especially in narrow or difficult-to-reach construction sites, the beams can be directly installed on site Casting and curing to meet different engineering needs; especially suitable for working conditions with tight engineering schedule or requiring quick response. When a construction section is completed faster than expected, the prefabrication and transportation integrated multifunctional beam transporter can be immediately adjusted to the new construction site without waiting for the production and transportation of traditional prefabricated beams; and because the beam body is directly cast on site, the proportion and quality of concrete can be adjusted immediately to ensure that it meets the needs of the specific project. This instant adjustment capability is often difficult to achieve in traditional prefabrication plants; on the other hand, because its design allows the beam body to be transferred directly from the beam transporter to the bridge erection machine, there is no need for a beam trolley. It not only simplifies the operating process, but also helps to reduce the overall working height. The beam transporter can be designed to be lower, which has greater advantages when passing through low tunnels or bridges.
