The invention provides an oil way tensioning mechanism and a shear fork type forward moving forklift, and relates to the technical field of forklifts.The oil way tensioning mechanism comprises a front frame; one end of the rubber tube is connected with the front frame, and the other end of the rubber tube is connected with the rear frame; the two ends of the outer fork arm are obliquely hinged to the front frame and the rear frame respectively; the two ends of the inner fork arm are obliquely hinged to the front frame and the rear frame respectively, and the inner fork arm and the outer fork arm are hinged in a crossed mode; a first roller; a second roller; the connecting plate is fixedly connected with the inner fork arm and is connected with the first roller and the second roller; the rubber pipe is connected with the front frame and the rear frame; when the front frame and the rear frame are close to each other, the rubber pipe abuts against the first rolling wheel and is attached to the second rolling wheel. When the front frame and the rear frame are away from each other, the rubber pipe abuts against the second rolling wheel and is attached to the first rolling wheel. The problems that due to frequent stretching and retracting actions caused by the change of the tensile force of the rubber pipe, the rubber pipe is continuously switched between tensioning and loosening, fatigue aging of a rubber pipe material is accelerated, and the risk of abrasion and breakage is increased are solved.
本申请提供一种油路张紧机构及剪叉式前移叉车,涉及叉车的技术领域,包括前架;后架,与前架平行设置,胶管一端与前架连接,另一端与后架连接;外叉臂,两端分别与前架与后架倾斜铰接;内叉臂,两端分别与前架与后架倾斜铰接,内叉臂与外叉臂交叉铰接设置;第一滚轮;第二滚轮;连接板,与内叉臂固定连接且连接第一滚轮和第二滚轮;胶管与前架和后架连接;当前架与后架相互靠近时,胶管与第一滚轮抵接,胶管与第二滚轮贴合;当前架与后架相互远离时,胶管与第二滚轮抵接,胶管与第一滚轮贴合。本申请解决胶管张紧力变化导致的频繁的伸缩动作,使得胶管在张紧与松弛之间不断转换,加速了胶管材料的疲劳老化,增加了磨损和破裂的风险的问题。
