Basket disk weighing system and aerial work platform with same

Abstract

The invention belongs to the technical field of engineering machinery, and relates to a basket disk weighing system and an aerial work platform with the same. The basket disk weighing system comprisesa weighing sensor and a basket assembly arranged on the weighing sensor in a pressing mode. The basket assembly comprises a basket and a basket bracket which are fixedly connected. The weighing sensor comprises a sensor outer ring and a sensor inner ring which are fixedly connected. The basket bracket is arranged on the weighting sensor in a pressing mode and fixedly connected with the sensor outer ring, and the sensor inner ring is connected to a driving arm assembly. The aerial work platform is provided with the weighting system to monitor the pressure borne by the basket in real time, overload is prevented, and safety of working high above the ground is improved; and the weighting system can solve the measurement problem of the real time load of the basket by using only one sensor, andhigh measuring veracity is achieved.

Problems solved by technology

[0002] Aerial work platforms are widely used in urban management, electricity, street lights, advertising, communications, viewfinder, gardens, transportation, docks, airport ports, large industrial and mining companies and other industries for installation, maintenance and climbing operations, and their safety has attracted much attention. Among them, overloading is one of the main causes of safety accidents. Therefore, the accuracy, effectiveness and real-time performance of overloading detection are necessary conditions for the safety of the whole vehicle. Some existing aerial work platforms are equipped with mechanical weighing systems. This kind of machinery The type only alarms when the rated load is exceeded, and cannot be monitored in real time, and during the use of the machine, due to the dynamic load, it is easy to make false alarms; some are equipped with hydraulic sensor weighing systems, which mainly combine The structure is calculated and matched, and the pressure in the actual hydraulic system needs to be combined. Sometimes the same model also needs to match the value of the hydraulic sensor according to the actual situation. In the actual production process, the efficiency is very low, and there are also false alarms during the dynamic load. Phenomenon; so it is still not very good to avoid the occurrence of safety accidents

[0003] For example, a Chinese utility model patent discloses an articulating arm type aerial work platform [application number: 201420766019.2]. The utility model includes a chassis, crawlers are installed on both sides of the chassis, a horizontal mechanism is installed on the Flat oil cylinder, a slewing mechanism is installed on the upper part of the horizontal mechanism, and a turntable is installed on the upper part of the slewing mechanism. The horizontal mechanism is used to adjust the level of the turntable. A level sensor is installed on the upper part of the horizontal mechanism. The level sensor senses the level of the chassis. Adjust the turntable to keep it level, and control the car body through the turntable control box on the turntable. The boom is installed on the turntable, and the boom can be stretched and adjusted. The boom is connected to one end of the swing motor, and the other end of the swing motor is connected to the upper end of the flying arm. Connection, the lower end of the fly arm is connected to the working column, and the swing motor can swing the working column horizontally from side to side. The lower part of the working column is fixed with a storage bucket, and the working column and the storage bucket drive the flying arm and the ground by their own weight. In the horizontal state, although the utility model has high stability and work efficiency, it is not equipped with a weighing system, which is prone to safety accidents

[0004] At the same time, the accuracy of the existing weighing system detection needs to be improved

[0005] For example, a Chinese utility model patent discloses a weighing device for aerial work platforms [application number: 201020684383.6], which includes a support shaft, a platform on the upper part of the support shaft, a pressure plate in the middle of the support shaft, and a lower part of the support shaft that runs through the platform bracket In the shaft sleeve, there is a rolling ball bearing between the support shaft and the shaft sleeve, the shaft sleeve end cover is arranged on the shaft sleeve, and the disc type sensor is arranged on the shaft sleeve end cover; the pressure plate on the support shaft passes through the thrust bearing Placed on the disc sensor, the utility model also has a thrust bearing between the platform and the disc sensor, so that when measuring the pressure, the pressure transmission passes through one more device, which affects the accuracy of the detection
