The invention discloses a tool for disassembling and assembling a brake in a pit of a vertical hydro-generator, which comprises the brake, a support truss, a hanging wheel, a chain block, a lifting bolt and a transfer cart, two hanging rails of the support truss are horizontally arranged on two sides of the brake in parallel, rail surfaces of the hanging rails are higher than the gravity center of the brake, the hanging wheel is arranged in the hanging rails, and the chain block is arranged on the transfer cart. One end of the chain block is hung on an annular lifting lug of the lifting wheel, the other end of the chain block is hooked on a lifting bolt on a brake bottom plate, a chain of the chain block is pulled, and the brake is upwards separated from a rack of the generator and then horizontally pushed to the outer side of the rack. And finally, the chain of the chain block is reversely pulled, so that the chain block falls onto the transfer cart on the ground in the pit and is transported out of the pit. And the brake can be reassembled by reverse operation. The tool can meet the requirement for dismounting the brake in a narrow space in a generator pit, the gravity center of the brake is always lower than a rail surface during dismounting, and the tool is not provided with an electric driving device and has the advantages of being simple in structure, convenient to mount, high in safety and the like.

    本发明公开一种立式水轮发电机机坑内的制动器拆装工具,由制动器、支撑桁架、吊轮、手拉葫芦、吊环螺钉、转运推车组成,支撑桁架的两根吊轨水平平行布置在制动器两侧,吊轨的轨道面高于制动器的重心高度,吊轮装在吊轨内,将手拉葫芦的一端挂在吊轮的环形吊耳上,另一端勾在制动器底板上的吊环螺钉上,拉动手拉葫芦的锁链,使制动器向上脱离发电机的机架,然后水平推至机架外侧,最后反向拉动手拉葫芦的锁链将其降落到机坑内地面上的转运推车上运出机坑。制动器回装时反向操作即可。本发明可以满足在发电机的机坑内部狭小空间拆装制动器需要,拆装时制动器的重心始终低于轨道面,工具无电驱动装置,具有结构简单、安装方便、安全性高等特点。
