Balance alarm and real-time protective device for aerial working platform of crawler travelling vehicle

Abstract

The invention discloses a balance alarm and real-time protective device for an aerial working platform of a crawler travelling vehicle, and the balance alarm and real-time protective device can be widely used to the field of agriculture and forestry picking and road greening. The balance alarm and real-time protective device comprises a crawler travelling system, four hydraulic cylinder telescopic supporting legs, four pressure sensors, an ECU controller, a rack, a gear, a hydraulic motor, an operation platform base, a transverse T-type slip rail, a slide block, a tertiary operation rod, an angle control hydraulic rod, and the aerial working platform. The balance alarm and real-time protective device is simple in structure, is stable in operation and is high in reliability. When staff works on the aerial working platform or when left-right displacement changes are to be carried out, the gravity center of the operation platform shifts while the pressure sensors of the hydraulic cylinders of the four supporting legs acquire a pressure value of each hydraulic supporting leg in real time and input the pressure value into the ECU controller to carry out stable performance analysis; when the gravity center shifts to be close to a system balance safety threshold, the system carries out timely alarm and opens a control valve of the hydraulic motor to drive the gear to rotate to drive the rack to move leftwards or rightwards, so that the crawler travelling system moves in a direction reverse to the gravity center shifting direction, and the gravity center of the operation platform is restored within a safety threshold range, and therefore, the safety of the aerial working platform is guaranteed.

Description

technical field [0001] The invention relates to a balance alarm and real-time protection device that can be widely used on a high-altitude operation platform on a crawler vehicle in the fields of agriculture, forestry picking and road greening. Background technique [0002] At present, most of the aerial work platforms in the domestic agriculture, forestry, picking and road greening industries set the left and right offsets of the work platform in advance according to the weight of the body and the weight of the platform load to ensure the stability of the body. However, in the actual operation process, the operator cannot control the load of the operation platform well, and the center of gravity moment of the operation platform increases when the operation platform is offset, which makes the operation platform very prone to roll accidents. At the same time, limited by the geographical environment and the working environment, sometimes the offset of the platform cannot reach...

Problems solved by technology

However, in the actual operation process, the operator cannot control the load of the operation platform well, and the center of gravity moment of the operation platform increases when the operation platform is offset, which makes the operation platform very prone to roll accidents

At the same time, limited by the geographical environment and the working environment, sometimes the offset of the platform cannot reach the corresponding working station. The general method is to readjust the position of the vehicle body to achieve this, which increases the workload and reduces the working efficiency.
