The utility model discloses a spare tire layout structure of a semi-trailer for powder material transportation. The root of several bolts is welded on the spare tire mounting plate, the spare tire mounting plate is placed on the rear side of the spare tire, the spare tire pressing plate is arranged in the interior of the spare tire, the two ends of the spare tire pressing plate are respectively against the inner wall of the spare tire, and a plurality of fixed holes corresponding to the bolts are opened on the spare tire pressi The holes are located in the central clearance of the spare tire. The bolts pass through the corresponding fixed holes and are fixed by nuts. The spare tire mounting plate is fixed on the rear frame of the semi-trailer. The hanger ears are fixed on the frame above the spare tire mounting plate, and the hand hoist is installed on the hanger ear. The hand hoist is connected with the spare tire. The utility model has novel structure and reasonable design, and provides a new solution for the spare tire placement of a semi-trailer for transporting powder materials with small wheelbase and large maximum section height of tank body. It solves the problems of small clearance between the spare tire and the ground, poor passability or no spare tire.
【技术实现步骤摘要】
一种粉粒物料运输半挂车备胎布置结构
本技术涉及专用车辆的备胎及备胎安装板
,尤其涉及一种粉粒物料运输半挂车备胎布置结构。
技术介绍
随着国家治超、限载力度的加大,目前市场上销售的粉粒物料运输半挂车多小型化、轴距短,尤其针对单仓干混砂浆车辆(粉粒物料运输半挂车的一种)最大截面高度尺寸大,若备胎安装板及备胎遵循常规结构放置在支腿与行走系统间的罐体V型车架处,备胎与地面间距低于设计标准及实际路况要求,严重影响车辆的行驶通过性。同时若粉粒物料运输半挂车不安装备胎安装板及备胎,影响车辆行驶的安全性和可维修性。
技术实现思路
本技术目的就是为了弥补已有技术的缺陷,提供一种粉粒物料运输半挂车备胎布置结构。本技术是通过以下技术方案实现的:一种粉粒物料运输半挂车备胎布置结构,包括有备胎和备胎安装板,在所述的备胎安装板上焊接有多个螺栓的根部,将备胎安装板放在备胎的后侧,在备胎的内部设有备胎压板,备胎压板的两个端部分别顶住备胎的内壁,在备胎压板上开有多个与所述的螺栓相对应的固定孔,所述的固定孔位于备胎的中心空隙处,所述的螺栓穿过与其相对应的固定孔,并通过螺帽固定,将所述的备胎安装板固定安装在半挂车的后端车架上,在所述的备胎安装板上面的车架上固定有吊耳,在吊耳上安装有手拉葫芦,所述的手拉葫芦与备胎连接。所述的备胎安装板和备胎位于半挂车后端后封头与后防护之间。在所述的半挂车的后防护的上面安装有备胎安装板安装导向板。所述的备胎安装板与粉粒物料运输半挂车车架连接可采用焊接式或栓接式。所述的备胎是这样实现升降的:将手拉葫芦挂在吊耳上,通过手拉葫芦升降备胎,同时在车辆后尾安装有导向板,便于备 ...
