The utility model discloses a hydraulic lock of the tail door of a dump truck, including small branch plate, oil cylinder, pin hook shaft, hook plate, and large branch plate. The small branch plate is set on the slot plate, one end of the oil cylinder is set on the small branch plate, and the pin is connected through the pin shaft A, the other end of the oil cylinder is connected with the hook plate and fixed with the opening pin. The large branch plate is in the hook. The hook plate is connected to the large plate through the pin shaft B, and the tail end of the hook plate is actively matched with the pin hook shaft welded under the rear door of the carriage. The pin hook shaft, the hook plate, the pin shaft B and the opening pin are provided with two, one hook plate, a pin shaft B and a opening pin constitute a hook plate component and two hooks. The board components are installed on the large plate, and the opening pin at the end of the two hook plates is synchronized through the driving plate, and a reset spring is arranged between the driving plate and the large branch board. The utility model has the advantages of convenient operation, and adopts the oil cylinder hook plate to fasten tightly the locking hook shaft to realize the tail door locking, the locking force is large, and the leakage is effectively prevented.
【技术实现步骤摘要】
一种自卸车尾门液压锁
本技术涉及一种自卸车领域,尤其涉及一种自卸车尾门液压锁。
技术介绍
自卸车运输介质非常广泛,像煤炭、铁矿石、土石方、砂石料、污泥、渣土等,现有自卸车传统车厢后门,锁紧不严,运输污泥、渣土等粉料、湿质、流质料时洒漏较为严重,对城市环境造成严重的污染。
技术实现思路
针对现有技术的不足,本技术提供一种操作方便,锁紧力大,有效防止洒漏的自卸车尾门液压锁。本技术的技术方案为:一种自卸车尾门液压锁,包括小支板、油缸、销钩轴、钩板、和大支板,其特征在于:所述小支板设置在槽板上,所述油缸一端设置在小支板上并通过销轴A连接,油缸另一端与钩板连接并用开口销固定,所述大支板在钩板两侧各设置一个,所述钩板通过销轴B连接在大支板上,所述钩板尾端与焊接在车厢尾门下的销钩轴活动配合,所述销钩轴、钩板、销轴B和开口销均设置有两个,一个钩板、一个销轴B和一个开口销构成一个钩板组件,两个钩板组件均安装在大支板上,两个钩板端部的开口销之间通过驱动板实现同步动作,所述驱动板和大支板之间设置有复位弹簧。所述复位弹簧两端设置在连接板上,所述连接板铰接在驱动板或大支板上。所述销钩轴一侧焊接有加强板,起到对销钩轴的结构增强效果。本技术有益效果为:操作方便,采用油缸上钩板扣紧锁钩轴,实现尾门锁紧,锁紧力大,有效防止洒漏。附图说明图1为本技术的侧视图。图2为本技术的俯视图。图中:1-大支板,2-油缸,3-销轴A,4-开口销,5-销钩轴,6-钩板,7-销轴B,8-小支板,9-加强板,10-槽板。具体实施方式下面结合附图对本技术的具体实施方式作进一步说明:如图1,图2所示,一种自卸车尾门液压 ...
