The invention belongs to the technical field of lifting devices, and particularly relates to a clamping mechanism of a concrete pipe lifting device, the clamping mechanism comprises a lifting cross beam, two pipe clamping jaws are slidably mounted on the lifting cross beam, the moving directions of the two pipe clamping jaws are opposite, the lower ends of the two pipe clamping jaws both extend to the lower portion of the lifting cross beam and are provided with semicircular grooves, and the semicircular grooves are arranged on the lifting cross beam. Bent reinforcing plates are fixedly connected to the two sides of the lifting cross beam correspondingly, the sides, away from the lifting cross beam, of the bent reinforcing plates extend to the positions below the pipe clamping jaws, an arc-shaped long groove is formed in the top of the pipe bearing table, and a concrete pipe body is placed in the arc-shaped long groove. According to the concrete pipe clamping device, when the servo motor works, the two pipe clamping jaws move oppositely, namely, the pipe clamping jaws pull the pipe bearing table through the inelastic rope, so that the pipe bearing table can synchronously move upwards before the pipe clamping jaws complete clamping, the interlocking movement effect is better, and the purpose of preventing concrete pipes from falling off can be achieved.

    本申请属于起重装置技术领域,尤其是涉及一种混凝土管起重装置的夹持机构,包括起吊横梁,所述起吊横梁上滑动安装有两个管夹爪,且两个管夹爪的移动方向相反,两个所述管夹爪的下端均延伸至起吊横梁的下方,并设有半圆形凹槽,所述起吊横梁的两侧均固定连接有弯曲加强板,且弯曲加强板远离起吊横梁的一侧延伸至管夹爪的下方,管承载台,所述管承载台的顶部开设有弧形长槽,且弧形长槽内放置有混凝土管本体。本发明中,伺服电机工作时,两个管夹爪将会相向移动,即管夹爪将会通过非弹性绳索拉动管承载台,使管夹爪在完成夹持前,管承载台能够同步上移,联锁运动效果更佳,并能够起到防止混凝土管掉落的目的。
