[0003] After the speed-difference self-controlling device is produced, the self-locking capability needs to be detected. At present, the detection method is that one end of the speed-difference self-controlling device is fixed, a worker rapidly pulls the safety rope of the speed-difference self-controlling device, when the moving speed of the safety rope is greater than the preset speed of the self-locking device, the speed-difference self-controlling device is self-locked, so that whether the self-locking capability of the speed-difference self-controlling device is qualified is detected. The detection speed of the self-locking capability of the speed-difference self-controlling device is slow by using the above detection method, the efficiency of the whole speed-difference self-controlling device being detected is affected, and the detection method needs to be improved. CONTENT OF THE INVENTION

[0005] The speed-difference self-controlling device detection device provided by the application adopts the following technical scheme:

[0006] The detection device comprises a detection table, a fixing piece connected to the detection table and a rotating rod rotatably connected to the detection table, the fixing piece is used for fixing the speed-difference self-controlling device, the rotating rod is connected to a mounting shell, the detection table is connected to a first driving piece used for driving the rotating rod to rotate and an inductive assembly corresponding to the rotating rod, when the rotating rod stops rotating, the inductive assembly receives a signal and transmits the signal to the first driving piece, and the first driving piece stops running.

[0007] The fixing piece fixes one end of the speed difference self-controller, and the safety rope of the speed difference self-controller is wound on the mounting shell. The first driving piece drives the rotating rod to rotate, that is, the mounting shell rotates around the axis of the rotating rod. In the process of rotation, the safety rope is wound on the mounting shell. When the rotating speed of the mounting shell is greater than the preset speed of the speed difference self-controller, the speed difference self-controller is locked, the safety rope cannot be pulled out from the speed difference self-controller, the safety rope limits the rotation of the mounting shell, and then the speed difference self-controller meets the requirements.

[0021] By adopting the above technical scheme, the hook can easily install the speed difference self-controller on the detection table, and also facilitates the removal of the speed difference self-controller from the detection table, thereby improving the efficiency of installing or dismounting the speed difference self-controller.

[0022] Optionally, the base is further connected with a rotating shaft, the detection table is rotatably connected with the base, the base is connected with a driving assembly for driving the detection table to rotate, the fixing member is a plurality of, the plurality of fixing members are distributed around the detection table, and the number of the fixing member, the rotating rod, the installation shell, the first driving member and the sensing assembly is the same.

[0042] The implementation principle of the speed difference self-controller detection device according to the embodiment of the present application is as follows:

After the winding of the safety rope is completed, the first driving member 23 drives the rotating rod 22 to rotate in the opposite direction. If the safety rope can be retracted into the speed difference self-controller, the retraction capability of the speed difference self-controller is qualified, otherwise the speed difference self-controller is unqualified.
