A rear plate limit device for dump truck includes a truck body, in which a limit device is arranged at the gap between the rear column of the side door and the back door plate, which is used to suppress the upstream and downward movement of the back door plate. The limit device consists of a left rack and a right rack, which are fixed on the rear column of the side door and the back door plate respectively, and the teeth of the left rack and the right rack can engage in the rear column of the side door and the back door plate. Together. The utility model adds a limit device on the existing cargo compartment to make up for the defect of the manual side lock hook assembly; the limit device is designed as a tooth meshing structure, which plays the role of upper and lower limit on the back door plate of the cargo compartment and avoids the problem of ups and downs of the back door plate of the cargo compartment when the dump truck is running; the utility model has the advantages of simple structure, easy assembly, low cost, convenient use and easy popularization. The application improves the safety and solves the problem of spilling granular goods.
【技术实现步骤摘要】
一种自卸车货厢后板限位装置
本技术属于自卸车货厢领域,尤其是一种自卸车货厢后板限位装置。
技术介绍
自卸车货厢后板齿形限位的装置是通过齿形限位机构控制货厢后板在行驶过程中上下窜动的机构。如图1所示,现有自卸车货厢后板限位装置俗称手动边锁钩总成。手动边锁钩总成是由手动锁钩1和锁钩销轴2组成。手动锁钩固定在边门后立柱3的下部外翼面上,边锁钩销轴固定在后门板4的下部侧翼面上。由于行驶路面工况凹凸不平的原因,货厢上下颠簸,造成货厢后门板在行驶过程中出现上下窜动,而现有自卸车货厢后门板限位装置俗称手动边锁钩总成,主要作用是防止货厢后板前后方向上的限制,而在上下方向上的限制存在缺陷,存在后门板与边板之间存在间隙较大的问题,并存在后门板有脱落的安全隐患。最简单的方法是将后板上下方向上的窜动进行有效限制。
技术实现思路
本技术提出一种自卸车货厢后板限位装置,解决现有货厢后门板在行驶过程中出现上下窜动的问题。为了解决上述技术问题,本技术的技术方案是:一种自卸车货厢后板限位装置,包括货厢本体,其特征在于:货厢本体上的边门后立柱与后门板之间的间隙处设有限位器,限位器用于抑制后门板上下窜动; ...
