The invention relates to the technical field of large-diameter pipeline transportation devices, in particular to a large-diameter PCCP pipeline self-discharging type transportation device which comprises a traction vehicle body and a pipe bearing semi-trailer vehicle body, and the pipe bearing semi-trailer vehicle body comprises a pipe bearing beam frame, a hydraulic jacking device, a front pipe limiting device, a rear pipe limiting device and a vehicle frame rising and falling device. The large-caliber PCCP loading and transporting vehicle is reasonable and compact in structure and convenient to use, the PCCP is jacked up from the interior through the hydraulic jacking device in the middle of the vehicle frame, the PCCP is fixed through the front pipe limiting device and the rear pipe limiting device and prevented from moving front and back, loading, transporting and unloading of the large-caliber PCCP can be independently completed under the condition that a large-tonnage crane is not used, and the working efficiency is improved. The problems of road height limitation and slow field unloading are effectively solved, the safety in the PCCP loading and unloading process and the passing capacity in the transportation process are effectively improved, the turnover rate of transportation vehicles is remarkably increased, the transportation cost and unloading cost of large-diameter PCCPs are greatly reduced, and the method has the advantages of being safe, capable of saving labor, simple, convenient and efficient.

    本申请涉及大口径管道运输装置技术领域,是一种大口径PCCP管道自卸式运输装置,其包括牵引车体和担管半挂车体,所述担管半挂车体包括担管梁架、液压顶升装置、前限管装置、后限管装置和车架起落装置。本申请结构合理而紧凑,使用方便,其通过车架中部的液压顶升装置将PCCP管道从内部顶起,通过前、后限管装置来固定PCCP管道、防止其前后窜动,能够在不使用大吨位吊车的情况下,独立完成大口径PCCP管道的装载、运输及卸货,有效解决了道路限高和现场卸车慢的问题,有效提高PCCP管道装卸过程的安全性以及运输时的通过能力,显著提高了运输车辆的周转率,大大降低了大口径PCCP管道的运输成本和卸车成本,具有安全、省力、简便、高效的特点。
