The invention relates to the technical field of constructional engineering machinery, and discloses a portable manual capstan small crane which comprises a bottom plate, movable wheels are fixedly arranged at the bottom of the bottom plate in a sliding mode, a thick arm is fixedly connected to the top of the bottom plate, a capstan is fixedly connected to the top of the thick arm, and a steel rope is movably connected to the outer surface of the capstan. And the top of the bottom plate is fixedly connected with a fixed seat. When the portable manual capstan small crane is used, a motor can be started to drive a second bevel gear to rotate, the second bevel gear rotates to drive a first bevel gear and a fixing pipe to rotate, due to the fact that threads are formed in the outer surface of the fixing pipe, the fixing pipe can drive a sleeve to ascend when rotating, and therefore the height of a cross arm can be adjusted; when the sleeve needs to be disassembled, the limiting block descends to the same horizontal position as the push plate, then the two push rods are pushed into the sleeve at the same time, and therefore the fiber block can be pushed into the movable groove, then the sleeve is moved upwards, and the effect of disassembling and replacing the s-shaped sleeve can be achieved.
本发明涉及建筑工程机械技术领域,且公开了便携式手动绞盘小吊车,包括底板,所述底板底部固定轮滑有活动轮,所述底板顶部固定连接有厚臂,所述厚臂顶部固定连接有绞盘,所述绞盘外表面活动连接有钢绳,所述底板顶部固定连接有固定座。该便携式手动绞盘小吊车,使用时,可以启动电机带动第二锥齿轮旋转,第二锥齿轮旋转带动第一锥齿轮和固定管旋转,由于固定管外表面开设有螺纹,所述固定管旋转时会带动套管上升,从而可以实现对横臂高度的调节,当需要将套管进行拆卸时,将限位块下降到与推板同一水平位,然后将两个推杆同时向套管内部推,从而可以使将纤维块推至活动槽内部,然后将套管向上移动,即可实现将套s管进行拆卸更换的效果。
