The invention discloses a low-bed semitrailer frame structure with a detachable gooseneck, particularly relates to the technical field of semitrailer frames, and comprises a frame body and a traction mechanism fixedly connected to the frame body. The traction mechanism is composed of a transfer column horizontally and slidably connected to the frame body and a traction column rotationally connected with the transfer column, a downward moving plate is arranged at the lower end of the traction column, a moving groove is formed in the lower side of the interior of the traction column, and a first storage groove is formed in the middle of the top wall of the moving groove; a mounting groove and an oil storage groove are formed in the middle side and the upper side of the interior of the traction column correspondingly, and a first groove is formed in the left side of the outer surface of the traction column. According to the frame structure of the low-bed semitrailer with the detachable gooseneck, the traction mechanism can be conveniently separated from the head of the semitrailer, meanwhile, the scraping rod can scrape off residual waste oil at the throat part of the traction seat through steering of the head of the semitrailer, and then the traction mechanism can continuously and normally work by spraying new lubricating grease.

    本发明公开了一种鹅颈可拆卸式的低平板半挂车车架结构,具体涉及半挂车车架相关技术领域,包括车架本体和固定连接在车架本体上的牵引机构,所述牵引机构由水平滑动连接在车架本体上的转接柱和与转接柱转动连接的牵引柱组成,所述牵引柱的下端设有下移板,所述牵引柱的内部下侧开设有移动槽,所述移动槽的顶壁中部开设有收纳槽一,所述牵引柱的内部中侧和内部上侧分别开设有安装槽和储油槽,所述牵引柱的外表面左侧开设有凹槽一。本发明所述的一种鹅颈可拆卸式的低平板半挂车车架结构,使得牵引机构在方便与车头分离的同时,还可以利用车头转向来使刮杆刮落牵引座喉部残留的废油,之后再通过喷射新的润滑油脂来使牵引机构可以持续正常工作。
