货车装载质量车载式辅助检测装置

Abstract

本实用新型涉及一种货车装载质量车载式辅助检测装置，通过将承载板、多个称重传感器安装在货车车斗内的方式，以便于对货车的装载质量进行检测。还可以采用其它方式检测货车装载质量，车辆在低速下驻车制动，利用车载仪测得平均制动减速度，调取货车空载时驻车制动减速度，通过比较装载状态和空载状态的减速度值，计算得到装载货车的整车质量。使用车载仪测量在平直路面上低速行驶的装载货车行车制动减速度，基于之前测得的货车装载质量计算空载货车或满载货车的等效行车制动减速度。当车载仪测得装载货车的整车质量后，与该车型额定总质量进行比对，超载后车载仪发出超载报警。车载仪连接监管平台，实现预防货车超载及定期检测货车行车制动性能。

2. The truck load quality on-board assist detection device of claim 1, wherein: Four screws are welded and fixed to the bottom plate of the truck bed at the positions corresponding to each of the weighing sensors. The four screws are located in the four mounting holes of the weighing sensors, and each of the four screws is screwed with a nut. The four nuts press down on the weighing sensors.

3. The truck load quality on-board auxiliary detection device of claim 1, wherein: A left baffle and a right baffle are fixedly provided on the left and right edges of the upper side of the bearing plate, respectively, and a front baffle is fixedly provided on the front edge of the upper side of the bearing plate. The bearing plate, the left baffle, the right baffle and the front baffle form a bearing bucket with an open rear end. It also includes a sealing part and a limiting part. The sealing part is detachably and fixedly connected to the rear end of the carrying bucket. The sealing part is used to close the rear end of the carrying bucket, and the limiting part is used to limit the front and rear position of the carrying bucket.

4. The truck load quality on-board assist detection device of claim 3, wherein: Multiple second bullseye bearings are fixedly mounted on the left baffle, and the balls of the second bullseye bearings abut against the left side wall of the truck bed. Multiple third bullseye bearings are fixedly mounted on the right baffle, and the balls of the third bullseye bearings abut against the right side wall of the truck bed. Multiple fourth bullseye bearings are fixedly mounted on the front baffle, and the balls of the fourth bullseye bearings abut against the front side wall of the truck bed.

5. The truck load quality on-board auxiliary detection device of claim 3, wherein: The closure includes a vertical plate and a limiting plate. The left and right ends of the front side of the vertical plate abut against the rear ends of the left and right baffles, respectively. The limiting plate is fixed to the front side of the vertical plate. The left side of the limiting plate abuts against the right side of the left baffle, the right side of the limiting plate abuts against the left side of the right baffle, and the lower side of the limiting plate abuts against the upper side of the bearing plate. The limiting part is used to press the vertical plate forward.

6. The truck loading weight on-board auxiliary detection device according to claim 5, characterized in that: The limiting part includes a fixing block, an insert plate, a fixing member, and a pressing assembly. The fixing block is fixed to the bottom plate of the truck bed and located behind the bearing plate. The upper side of the fixing block is lower than the lower end face of the vertical plate. The upper side of the fixing block is recessed downward to form a slot. The lower end of the insert plate is inserted into the slot. The fixing member is used to fix the lower end of the insert plate in the slot. The pressing assembly is disposed on the insert plate and is used to press the vertical plate forward.

7. The truck load quality on-board auxiliary detection device of claim 6, wherein: A first screw hole is formed on the fixing block. One end of the first screw hole is connected to the slot and the other end is connected to the rear side of the fixing block. The fixing member includes a first bolt screwed into the first screw hole. The screw-in end of the first bolt abuts against the rear side of the lower end of the insert plate.

8. The truck load quality on-board auxiliary detection device of claim 6, wherein: A second screw hole is formed on the insert plate. The extrusion assembly includes a second bolt and a fifth bullseye bearing. The second bolt is screwed into the second screw hole. The fifth bullseye bearing is fixed to the screw-in end of the second bolt. The balls of the fifth bullseye bearing abut against the vertical plate.
