Problems solved by technology

[0006] Since the detection switch expands and contracts with the oil cylinder, the detection switch is easy to touch the accumulated water on the ground, resulting in the failure of the detection switch; moreover, the pull rope hanging on the vertical oil cylinder is easily caught by the exposed objects on the ground, the detection process is unsafe, and the detection results are not reliable

Abstract

The invention discloses a device for detection the stress of a supporting leg of an engineering vehicle. The device comprises a detection switch for detecting the stress of the supporting leg of the engineering vehicle, wherein the supporting leg comprises a fixed supporting leg (1) fixedly connected with the body of the engineering vehicle and a vertical oil cylinder (2) arranged on the externalend part of the fixed supporting leg; when the supporting leg is under the non-working state, a predetermined distance is formed between the fixed support leg (1) and the vertical oil cylinder (2); when the supporting leg is under the working state, the distance between the fixed support leg (1) and the vertical oil cylinder (2) is smaller than the predetermined distance; the detection switch measures the stress of the supporting leg according to the distance change between the fixed support leg (1) and the vertical oil cylinder (2). The device for detecting the stress of the supporting leg can detect the stress of the supporting leg conveniently, and the detection result is accurate and reliable. The invention further provides an engineering vehicle comprising the device for detecting the stress of the supporting leg.

Description

technical field [0001] The invention relates to the field of engineering machinery detection, in particular to a force detection device for outriggers of engineering vehicles. In addition, the present invention also relates to an engineering vehicle comprising the above-mentioned outrigger force detection device. Background technique [0002] With the rapid development of my country's economic construction, various engineering vehicles continue to emerge and are used in many industries. [0003] When engineering vehicles such as aerial work vehicles need to get on the vehicle, the force signal of the outriggers must be fed back to the control of the vehicle when getting off the vehicle, so that the vehicle can move, otherwise the vehicle cannot be operated. Judging whether the outrigger is stressed or not needs to provide a judgment value to the detection switch, and when the outrigger is stressed or not, the judgment value will change. [0004] In the prior art, the force...
