Problems solved by technology
For example, when the passive anti-extrusion device detects incorrectly when the operator's operation range is slightly large or the body is slightly out of balance, the operating equipment will automatically stop working, seriously affecting normal construction operations
The active anti-extrusion device may not play a protective role because the push rod is stuck

The invention discloses an anti-extrusion device which comprises a detection rod, a detection sensor and two connecting parts used for being connected with an aerial work platform, each connecting part comprises at least one elastic connecting part, and the detection sensor is connected with a control system of the aerial work platform and used for measuring the displacement amount of the detection rod. The two ends of the detection rod are connected with the two connecting parts respectively. When the aerial work platform is extruded, an operator can bend to avoid and extrude the detection rod. The elastic connecting part moves after being stressed, the detection sensor measures the displacement, and if the displacement amount is too large, the aerial work platform is stopped. And the detection rod is supported by the connecting part, enough deformation can be generated by extrusion of an object with a certain mass, and the risk of false detection is reduced. In addition, the detection rod shifts through downward pressing, the requirement for space is low, and the detection rod is not prone to being clamped. And the reliability of the anti-extrusion device is ensured. The invention further provides the aerial work platform comprising the anti-extrusion device, and the aerial work platform has the advantages.
Description
technical field [0001] The invention relates to the technical field of aerial work equipment, in particular to an anti-extrusion device. The present invention also relates to an aerial work platform comprising the above-mentioned anti-extrusion device. Background technique [0002] Aerial work platforms are commonly used machinery and equipment for construction personnel to work at heights. The safety of aerial work platforms is directly related to the safety of construction personnel, so it has received close attention from the state and society. Aerial work platform accidents are mainly crush casualties caused by operating errors. [0003] There are multiple anti-extrusion technical solutions in the prior art. It is mainly divided into passive anti-extrusion through detection means and active anti-extrusion through user operation. But existing anti-extrusion device still has problems. For example, when the passive anti-extrusion device detects incorrectly when the oper...
