Abstract

The invention provides a work bucket load sensing mechanism and an aerial work vehicle, comprising a bracket, a work bucket bracket, and two connecting frames. The bracket, the work bucket bracket, and the two connecting frames form a four-bar linkage mechanism; The brackets are respectively equipped with travel switches, which are used to sense the up and down deflection strokes of the two connecting frames; the two connecting frames are connected by a first rod, and a spring is sleeved on the first rod, and the spring is used to make the two connecting frames Reset to the initial state; in the no-load state, the connecting frame is pressed against one of the travel switches; in the first load state, neither the connecting frame is pressed against the two travel switches; in the second load state, the connecting frame will be pressed against Another travel switch. The invention adopts the opposite design of two travel switches, has ingenious structure, reliable performance, and can detect three states. The limit block and limit bolt are designed to prevent the travel switch from being crushed.

Description

Technical field: [0001] The invention belongs to the field of machinery, and particularly relates to a work bucket load sensing mechanism and an aerial work vehicle. Background technique: [0002] In order to ensure the safety of the operation, the aerial work platform usually limits the weight of the load in the working bucket of the aerial work platform. In order for the aerial work platform to work with the highest efficiency, it is hoped that the load that the work bucket can bear can be maximized, and at the same time, the working range of the boom is hoped to be maximized. Clearly, load capacity and operating range are a pair of conflicting factors. In order to solve this contradiction, two kinds of load capacity are usually designed in the design of high-altitude work platforms. When the load is small, the working range of the boom is larger; when the load is large, the working range of the boom is smaller. Therefore, a load detection device is needed at this time, ...
