The invention relates to the related field of building feeding, and discloses an automatic fixing device for vertical hoisting of steel pipes. The automatic fixing device comprises a main body block;a middle cavity is arranged in the main body block; the upper side of the middle cavity is provided with a top cavity in a communicating mode; the left and right sides of the middle cavity are symmetrically provided with fixed claw grooves with openings away from the middle cavity in a communicating mode, so that the device body can move in the inner wall of a steel pipe within a certain pipe diameter range, and enter from one side and drill out from the other side; a mechanical fixing claw can be automatically opened at the moment of drilling out so as to fix the single steel pipe, and the steel pipe fixed through the device is suitable for the transportation of a small number of (single) steel pipes; and an operator only needs to put the device into the pipe wall to open a switch to automatically complete subsequent steps, vertical transportation of pipes can be achieved after fixing is completed, due to the self-locking performance of the device, safety in the hoisting process is guaranteed, after transportation is completed, the operator only needs to tighten the mechanical claw and pull a line replacing rope, and the device can automatically exit the steel pipe.

    本发明涉及建筑送料相关领域,公开了一种钢管竖直吊装自动固定装置,包括主体块,所主体块内设有中间腔,中间腔上侧连通设有顶部腔中间腔左右两侧对称连通设有开口远离中间腔方向的固定爪槽,使得装置本体能在一定管径范围内的钢管内壁中进行运动,由一侧进入,从另一侧钻出,在钻出的一瞬间能够自动打开机械固定爪,以此完成对单根钢管的固定,通过该装置固定的钢管适用于少量(单根)的钢管运输情形,操作者只需将该装置放入管壁打开开关便可自动完成后续步骤,在固定完成后,便可实现管材的竖直运输,由于装置的自锁性,在吊装过程中安全性得到保证,当完成运输后,操作者只需收紧机械爪,并拉动换线绳,装置便可自行退出钢管。
