Pushing device for erecting steel box girder
The invention discloses a pushing device for erecting a steel box girder, belongs to the field of buildings, and aims to solve the problems that in order to reduce friction generated during pushing, balls are mounted at sliding positions of an existing pushing device for the steel box girder, but the balls are very easily damaged by falling broken stones due to the fact that the balls are mounted on the outer sides, and pushing is strenuous. A pushing device for erecting a steel box girder comprises a base, a first hydraulic cylinder arranged on one side of the upper portion of the base, a first hydraulic rod fixedly connected to the output end of the first hydraulic cylinder, a first sliding groove formed in the inner side of the base and a first sliding block arranged on the inner side of the first sliding groove. When the first hydraulic cylinder is pushed, the pushing mechanism is driven to move towards the two sides, so that blocking of the first sliding groove is opened, when the first hydraulic cylinder moves beyond the range of the pushing mechanism, the pushing mechanism is reset, and compared with the prior art, damage of falling rocks to balls can be prevented, and therefore the situation that the balls are damaged is reduced.
一种钢箱梁的架设用顶推装置，属于建筑领域，为解决了现有的钢箱梁顶推装置为了减小推动时产生的摩擦，在滑动的位置安装滚珠，但是滚珠有安装在外侧非常容易将掉落的碎石对滚珠发生损坏，使得推动费力的问题，一种钢箱梁的架设用顶推装置，包括有底座，设置在底座上方一侧的第一液压缸，固定连接在第一液压缸输出端的第一液压杆，设置在底座内侧的第一滑槽，设置在第一滑槽内侧的第一滑块，通过设置有推动机构，在第一液压缸进行推动时带动推动机构向两侧进行运动，使得第一滑槽的阻挡打开，在第一液压缸运动过推动机构的范围时，推动机构进行复位，相对于现有技术，可以防止落石对滚珠的破坏，从而减小滚珠发生损坏情况的发生。
