The invention provides a self-locking cantilever beam, a bearing device and an operation platform and relates to the technical field of construction tools. The self-locking cantilever beam comprises a cross beam and a clamping assembly arranged at one end of the cross beam. The clamping assembly can achieve the self-locking function. The clamping assembly comprises a first clamping part, a second clamping part, a connecting rod and a locking part. The first clamping part is arranged at one end of the cross beam. The two ends of the connecting rod are connected to the cross beam. The second clamping part is arranged on the connecting rod in a penetrated mode. The second clamping part can move close to or far away from the first clamping part to form a range adjustable clamping space between the first clamping part and the second clamping part. When the second clamping part moves to a preset position, the locking part can lock and limit displacement of the second clamping part so as to complete mounting of the
