Bridge pushing assembly utilizing gear transmission
The invention, which belongs to the field of weight conveying mechanisms, discloses a bridge pushing assembly utilizing gear transmission. The bridge pushing assembly comprises a shell, a jacking oilcylinder and a pushing table; a gear transmission mechanism used for pushing the pushing table to move horizontally is arranged in the shell. The gear transmission mechanism comprises an output gear;the output gear is a tooth-missing gear; the lower portion of the pushing table is provided with two transmission plates located on the two sides of the output gear respectively. One side, facing theoutput gear, of each of the two transmission plates is respectively provided with a carry rack and a return rack; when the carry rack is meshed with the output gear, the pushing table is controlled tocarry; when the return rack is meshed with the output gear, the pushing table is controlled to return, the output gear only needs to rotate in one direction to control the pushing table to move backand forth, so that the service life of the device is prolonged. The bridge pushing assembly can adapt to higher-speed pushing, and a problem that in the prior art, an oil cylinder controls the pushingtable to move back and forth, and consequently damage is likely to be caused by hydraulic impact is solved.
本发明公开了一种利用齿轮传动的桥梁顶推组件，属于重物运送机构领域，包括外壳、顶升油缸、顶推台，所述外壳内设有用于推动顶推台水平运动的齿轮传动机构，所述齿轮传动机构包括输出齿轮，所述输出齿轮为缺齿齿轮，所述顶推台下部设有两块分别位于输出齿轮两侧的传动板，两块传动板朝向输出齿轮的一侧上分别设有进位齿条和退位齿条，所述进位齿条与输出齿轮啮合时控制顶推台进位，所述退位齿条与输出齿轮啮合时控制顶推台退位，输出齿轮只需单向转动即可控制顶推台来回运动，提高装置使用寿命，并且能适应更高速的顶推，解决了现有技术中用油缸控制顶推台的来回运动导致容易由于液压冲击而损坏的问题。
