The invention discloses a parking brake device and a roller, which is installed on the frame and is close to the bump wheel of the roller. The parking brake system consists of the installation seat, the stop shaft, the positioning spring, the positioning pin, the tight spring, the cylinder sleeve and the handle. There are guide grooves on the cylinder sleeve. The guide groove is composed of the upper stop, the lower stop, the installation slot, the upturn slot, the downward slot and the moving slot. The upper and lower turning grooves are connected with the moving grooves, and the installation grooves are located on the moving grooves, and there is an axial distance between the upper and the lower stops. Under the action of pressing spring spring force, the stop shaft can be locked in the upper and lower stops, thus realizing the extension and retracting of the stop axis. When the stop shaft is extended to the gap between the convex block and the convex block, the rotation of the bump wheel is stopped and the brake is realized; when the stop shaft is retracted, the brake is lifted. The parking brake device provided by the invention has the advantages of simple structure, easy operation, reliable braking and convenient maintenance, which can avoid braking failure due to vibration and improve the safety of road roller.
【技术实现步骤摘要】
一种驻车制动装置及压路机
本专利技术涉及一种驻车制动装置,以及采用了该驻车制动装置的压路机。
技术介绍
小型压路机可分为光轮压路机和凸块轮压路机,凸块轮压路机其滚轮表面带有多个按规律排列的凸块,各凸块沿圆周分布且相互之间存在空隙。小型凸块轮压路机常用于基础铺层的压实,该压路机一般均配有驻车制动装置,当压路机已停机、驾驶人员离开时或压路机停在坡道上时,启动驻车制动装置可避免压路机移动造成意外伤害。现有技术中,小型凸块轮压路机的驻车制动装置一般采用楔块,即当驾驶员离开压路机或压路机停在坡道上时,将楔块放置在地面上,并顶紧在轮子的前后下方,以阻止车轮滚动。由于楔块是插在机身上的楔块架中,在压路机使用过程中常常出现丢失的现象,同时该制动方式操作繁琐,可靠性不高。
