Description
技术领域technical field
本发明涉及桥梁工程领域，特别涉及一种可行于板-梁的桥道板运输安装车。The invention relates to the field of bridge engineering, in particular to a bridge road slab transportation and installation vehicle applicable to slab-beams.
背景技术Background technique
在公路桥梁工程中，由于使用方便的特点，预制板作为桥道板得到了广泛的应用。现有技术中，桥梁预制板安装方法有自行式吊机架设法进行安装就位，即直接用吊车将预制板吊装到安装位置，此方法需要大型的起吊运输设备和施工场地，吊装时吊车起重臂工作半径和工作高度范围内，不得有输电线路和其它障碍，在受空间和平面尺寸限制的条件下不宜使用，另外，因考虑到桥梁下通常有水，可采用卷扬机配合导链架设法，在桥体两端架设临时支架，在桥体外侧纵向铺设双向轨道，桥一端卷扬机固定在桥头，另一端卷扬机分别固定在各墩台上并可移动，通过卷扬机纵向移梁，并采取手拉葫芦与钢管横向移梁，依次安装预制板，该方法操作复杂，需要耗费大量的时间和人力，并需要耗费大量的资金，且吊装过程中岗位的安全稳定性不足。并且，桥梁预制板安装时为保证桥梁整体受力平衡需要自桥梁中间向两端依次对称铺设，针对该要求，上述两方法均存在操作复杂，不便移动的问题，而且上述两方法均需要在桥体外侧架设设备，大大提高了架设成本。In highway and bridge engineering, prefabricated slabs are widely used as bridge slabs due to their ease of use. In the prior art, the installation method of bridge prefabricated panels has a self-propelled crane frame to try to install them in place, that is, directly hoist the prefabricated panels to the installation position with a crane. This method requires large-scale lifting and transportation equipment and a construction site. Within the range of the working radius and working height of the heavy arm, there must be no transmission lines and other obstacles, and it is not suitable for use under the conditions of space and plane size restrictions. In addition, because there is usually water under the bridge, a hoist can be used to cooperate with the chain guide frame. , set up temporary supports at both ends of the bridge body, and lay two-way tracks longitudinally on the outside of the bridge body. The hoist at one end of the bridge is fixed at the bridge head, and the hoist at the other end is respectively fixed and movable on each pier. The beam is moved longitudinally by the hoist and manually The hoist and steel pipe move the beam horizontally and install the prefabricated slabs sequentially. This method is complicated to operate, requires a lot of time and manpower, and requires a lot of money, and the safety and stability of the post during the hoisting process is insufficient. Moreover, in order to ensure the overall force balance of the bridge during installation, the bridge prefabricated panels need to be laid symmetrically from the middle of the bridge to both ends. In view of this requirement, the above two methods have the problems of complicated operation and inconvenient movement, and both of the above two methods need to be installed on the bridge. Erection of equipment on the outside of the body greatly increases the erection cost.
因此，针对在已建成钢桁架上铺设桥道板，需要一种在桁架梁和已铺设桥道板上均可通行的运输安装设备，具有便于移动，方便使用，结构简单的特点，可承载桥道板在桥梁桁架和铺设好的桥道板上行走，并且可方便快捷安全的对桥道板进行安装，大大减少人力、时间和资金的耗费。Therefore, for the laying of bridge slabs on the completed steel trusses, a transportation and installation equipment that can pass through both the truss girders and the laid bridge slabs is needed. It is easy to move, easy to use, and simple in structure. The road slab walks on the bridge truss and the laid bridge road slab, and can be installed conveniently, quickly and safely on the bridge road slab, greatly reducing the cost of manpower, time and money.
