本发明属于滑轮技术领域,尤其涉及一种多线滑轮设备,它包括供钢绳绕过的滑轮机构、固定滑轮机构和安装牵引绳的滑轮悬臂、连接滑轮机构和滑轮悬臂的销轴,在对滑轮悬臂同等要求的情况下,本发明设计的卸扣式滑轮中的滑轮悬臂相对于传统的卸扣式滑轮上的滑轮悬臂的臂距要短;长时间使用后本发明的滑轮悬臂与滑轮机构之间面与面配合的间隙增大程度较小,进而间隙卡钢绳的机率也相对较小,使用寿命较长;本发明中滑轮悬臂是由两个第一悬臂和两个第二悬臂组成,在需要两个牵引绳从不同方向牵动的时候,将由两个第一悬臂和两个第二悬臂分别向两侧展开,形成两个不同方向的滑轮悬臂的牵引点,每个方向牵引点的滑轮悬臂均为双侧结构,强度较高。

    The invention belongs to the technical field of pulleys, and particularly relates to a multi-wire pulley device which comprises a pulley mechanism for a steel rope to bypass, pulley cantilevers for fixing the pulley mechanism and installing traction ropes, and a pin shaft for connecting the pulley mechanism with the pulley cantilevers. Under the condition of the same requirements on the pulley cantilevers, compared with a pulley cantilever on a traditional shackle type pulley, the pulley cantilevers in the shackle type pulley designed by the invention have the advantages that the arm distance is shorter; after long-time use, the increase degree of the face-to-face fit clearance between the pulley cantilevers and the pulley mechanism is small, then the probability that the clearance clamps the steel rope is relatively low, and the service life is long; and the pulley cantilevers are composed of two first cantilevers and two second cantilevers, when the two traction ropes need to be pulled in different directions, the two first cantilevers and the two second cantilevers are unfolded towards the two sides respectively to form traction points of the two pulley cantilevers in different directions, and the pulley cantilevers with the traction points in each direction are of a bilateral structure, so that the strength is high.
