Dumper lifting safety monitoring device and method

Abstract

The invention provides a dumper lifting safety monitoring device and method. The device comprises an angle sensor, an oil pressure sensor, a central control device and a cab display device; the oil pressure sensor is arranged at an oil port of a hydraulic cylinder to collect oil pressure; the angle sensor is arranged above an overturning shaft and in the center of the abdomen of a carriage and isused for collecting the angle of the carriage. According to the technical scheme, the dumper lifting safety monitoring device has the advantages that on one hand, the lifting angle and heeling angle of the carriage can be monitored in real time, the oil circuit pressure can be monitored in real time, carriage lifting abnormity is comprehensively analyzed, assessed and identified in combination with the goods weight, and possible rollover accidents can be predicated; on the other hand, the goods loading weight of a vehicle can be calculated, warning of overload is performed, the work weight iscounted, and maintenance recommendations are provided for a vehicle lifting system; weighing and weight control are achieved simultaneously, the efficiency is high, remote monitoring is achieved, andthe accuracy is good.

Description

Technical field [0001] The invention belongs to the technical field of dump trucks, and specifically relates to a dump truck lifting safety monitoring device and method. Background technique [0002] The dump truck lifting safety monitoring device is mainly divided into two parts, one is the weighing part, and there are two main methods: one is to drive the loaded truck to a fixed platform scale for weighing and then subtract the weight of the vehicle. The weighing method must be driven to a fixed measuring station to weigh the goods. It cannot be weighed and controlled while loading. It has low efficiency and cannot be remotely monitored and managed. The other is between the truck compartment and the chassis beam. Install a pressure sensor to monitor the weight. This method can monitor the weight of the car in real time, but it has the disadvantage of large error and easy damage. The second is the body condition monitoring part, which mainly uses the angle meter installed at th...

[0002] The dump truck lifting safety monitoring device is mainly divided into two parts. One is the weighing part. There are two main methods: one is to drive the loaded car to a fixed platform scale for weighing and then subtract the car's own weight. The weighing method must travel to a fixed metering station to weigh the goods. It cannot weigh and control the weight while loading, and the efficiency is low, and it cannot be monitored and managed remotely; the other is between the truck compartment and the chassis girder. Install a pressure sensor between them to monitor the weight. This method can monitor the weight of the car body in real time, but it has the disadvantages of large error and easy damage.

The second is the body condition monitoring part, which mainly adopts the angle meter installed at the bottom of the dump truck body. This method simply monitors the roll angle to prevent rollover. It cannot be comprehensively analyzed and evaluated with the lifting angle and the weight of the car body. poor sex
