[0002] 随着我国大量新建桥梁工程的推进及旧有桥梁的损伤累计, 目前桥梁检测与加固施 工工程量较大。 虽然目前市场上已有一些专业的吊篮产品出售, 但是它们有一个共同特点: 跨度小, 一般为 5米〜 12米, 售价高, 且无法快速组装, 运输难度大和耗费高, 无法适应桥 梁结构常态化的检测与加固施工要求。 现阶段很多桥梁施工或检测工程中, 大量使用的自制 吊篮平台, 吊篮由各单跨通过节点螺栓拼装而成, 其组装难度较高, 并且不便于运输。 吊篮 通过大量螺栓将众多杆件逐一拼装而成, 螺栓连接工作量大, 且耗时长, 以 28密跨吊篮为 例, 5人同时作业所需拼装时间为 5小时, 不利于提高工程施工效率和节约工程成本。 [0002] With the advancement of a large number of new bridge projects in China and the accumulation of damage to old bridges, the amount of bridge inspection and reinforcement construction is currently large. Although there are some professional hanging basket products on the market, they have one common feature: small span, generally 5 meters to 12 meters, high price, and can not be assembled quickly, difficult to transport and expensive, unable to adapt to the bridge Structural normalization testing and reinforcement construction requirements. At present, in many bridge construction or inspection projects, the self-made basket system is widely used. The baskets are assembled by single bolts through joint bolts, which is difficult to assemble and is not easy to transport. The basket is assembled by assembling a large number of bolts one by one. The bolting work is large and takes a long time. Taking the 28-deep basket as an example, the assembly time required for 5 people to work at the same time is 5 hours, which is not conducive to improving the construction.

However, the structure of the device is complicated, cannot be assembled and disassembled quickly, and cannot be integrally stretched and unfolded. It is difficult, time-consuming and labor-intensive to assemble and disassemble, occupying a large space, and being inconvenient to transport, which is not conducive to improving the construction efficiency of bridge maintenance.
