The invention provides a cable towing device and engineering machinery, and the cable towing device comprises a swing rod; the hydraulic mechanism is connected with the swing rod, and a hydraulic medium is stored in the hydraulic mechanism; the drag chain is connected with the swing rod through a hydraulic mechanism, the swing rod can drive the drag chain to move, and under the condition that the drag chain moves, the drag chain can adjust the pressure intensity generated by the hydraulic medium on the hydraulic mechanism; and the detection part is connected with the hydraulic mechanism and is used for detecting the pressure intensity generated by the hydraulic medium on the hydraulic mechanism. According to the cable towing device provided by the invention, the hydraulic mechanism is arranged, and the hydraulic mechanism is a pure mechanical mechanism and does not comprise electrical elements such as a chip, so that the hydraulic mechanism is less affected by temperature, humidity, gas and corrosive gas in a construction environment, and on the basis of realizing real-time detection of cable tension, the cable towing device is more convenient to use. The application stability of the towing cable device is effectively guaranteed, and the service life is prolonged.
本发明提出了一种拖缆装置和工程机械,其中,拖缆装置包括:摆杆;液压机构,与摆杆连接,液压机构中存储有液压介质;拖链,通过液压机构与摆杆连接,摆杆能够带动拖链运动,在拖链运动的情况下,拖链能够调整液压介质对于液压机构所产生的压强;检测部,与液压机构连接,用于检测液压介质对于液压机构所产生的压强。本发明提供的拖缆装置,通过设置液压机构,液压机构为纯机械机构,并不包括芯片等电器元件,从而使得液压机构在施工环境中受温度、湿度、瓦斯以及腐蚀性气体的影响较小,从而在实现了对线缆张紧力的实时检测的基础上,有效地保证了拖缆装置的运用稳定性,提高了运行寿命。
