Bridge precast beam hoisting point conversion device and precast beam hoisting method thereof
The invention discloses a bridge precast beam lifting point conversion device which comprises a rigid cross rod, a triangular flange plate, first lifting ropes, second lifting ropes, third lifting ropes and fourth lifting ropes, one side of each of the two ends of the rigid cross rod is connected with one side of one first lifting rope, and the other sides of the two first lifting ropes are connected with the triangular flange plate to form a flexible triangle. The other sides of the two ends of the rigid cross rod are connected with a second lifting rope and a third lifting rope respectively, and the triangular flange plate is further connected with a fourth lifting rope towards the outer side. The rigid cross rod is adopted, so that a certain safe distance is kept between two lifting points of the lifting point conversion device, and mutual interference of steel cables of the crane can be avoided; field assembly is convenient, the weight is light, and transportation is convenient; the workload of site construction preparation and debugging is effectively reduced, and the traffic pressure of equipment transportation is avoided; even if the field around the bridge is limited, double-vehicle lifting can be adopted, the requirement for a crane is lowered, and the applicability is high.
本发明公开了一种桥梁预制梁吊点转换装置，包括刚性横杆、三角法兰盘、第一吊绳、第二吊绳、第三吊绳及第四吊绳，所述刚性横杆两端的一侧各连接一个第一吊绳一侧，两个第一吊绳的另一侧与三角法兰盘连接形成柔性三角形，所述刚性横杆两端的另一侧分别连接第二吊绳及第三吊绳，三角法兰盘朝外侧还连接第四吊绳。采用刚性横杆，保证吊点转换装置的两个吊点间有一定安全距离，可避免起重机钢缆的相互干扰；现场组装方便，重量轻，便于运输；有效的减小了现场施工准备、调试的工作量，无设备运输的交通压力；即便桥梁周围场地受到限制，也可采用双车抬吊，降低了对起重机的要求，适用性强。
