The invention relates to the technical field of gantry cranes, and discloses a sliding gantry crane which comprises a bridge frame, supporting legs are fixedly mounted at the left end and the right end of the bridge frame, a sliding plate is slidably connected into the bridge frame, and adjusting mechanisms are fixedly mounted at the left end and the right end of the sliding plate. According to the sliding gantry crane, in the process that the top plate slides on the upper surface of the bridge frame, the inflation device is driven to move under the action of the sliding wheels, gas generated by the inflation device enters the sliding plate, a semicircular ring deforms under the action of the gas, and the semicircular ring deforms as long as the sliding plate moves; when the sliding plate is lifted, the semicircular ring deforms to be matched with the extrusion rod to drive the limiting rod to move, the limiting rod is separated from the winding wheel, so that the position of the winding wheel can be adjusted in the vertical direction in the moving process of the sliding plate, the winding wheel is perpendicular when the sliding plate is fixed, and the stability of the winding wheel can be guaranteed when the winding wheel is lifted.
本发明涉及龙门起重机技术领域,且公开了一种滑动龙门式起重机,包括桥架,所述桥架的左右两端均固定安装有支撑腿,所述桥架的内部滑动连接有滑动板,所述滑动板的左右两端均固定安装有调节机构。该滑动龙门式起重机,通过在顶板在桥架的上表面上滑动过程中,会在滑动轮的作用下带动充气装置运动,充气装置产生的气体会进入到滑动板的内部,半圆环会在气体的作用下产生变形,只要滑动板运动,半圆环就会产生变形,半圆环变形就会配合挤压杆带动限位杆运动,限位杆会脱离缠绕轮,从而缠绕轮在滑动板运动过程中,可以进行竖直方向上的位置调整,在滑动板固定时,缠绕轮会垂直,从而可以保证了吊起时,缠绕轮的平稳性。
