The invention relates to the technical field of hoisting equipment, and discloses safety hoisting equipment for constructional engineering construction. A movable tensioning hook is arranged on a fourth connecting block, the position of the tensioning hook corresponds to the position of a locking block, a grasping structure comprises a movable grasping block, a movable moving block is arranged on the side face of the grasping block, and the movable moving block is arranged on the side face of the grasping block. A hydraulic locking rod is arranged on the upper side of the grabbing block. According to the truss grabbing device, when a truss is too long and needs to be grabbed by two sets of devices, a fifth connecting block and a connecting rod are moved, a locking block is moved to a tensioning hook from the outer side of the truss, then the tensioning hook is moved, and the tensioning hook hooks the locking block through a locking cavity to form a chain to support the truss; when the clamped truss is too long and the two ends of the clamped truss are asymmetric, the supporting columns of the truss are located in the grabbing blocks through the movable grabbing blocks, and then the supporting columns of the truss are extruded through the hydraulic locking rods, so that the stability in the using process is improved.
本发明涉及起重设备技术领域,且公开了一种用于建筑工程施工建设的安全起重设备,第四连接块上设置有活动的拉紧钩,拉紧钩的位置与锁紧块的位置相对应,所述抓紧结构包括可以活动的抓块,抓块的侧面设置有可活动的移动块,抓块的上侧设置有液压锁紧杆。本发明中,当桁架过长需要两组装置进行抓取的时候,移动第五连接块和连接杆,使锁紧块从桁架的外侧移动至拉紧钩上再移动拉紧钩,拉紧钩通过锁紧腔勾着锁紧块形成一个锁链来对桁架进行支撑,当夹持的桁架过长且两端不对称的时候,通过可以移动的抓块使桁架的支柱处于抓块的内部,再通过液压锁紧杆对桁架的支柱进行挤压,来提高使用过程中的稳定性。
