The invention provides a movable revolving stage. Compared with a traditional stage, it saves time and labor to set up the movable revolving stage, the change space is larger and the adaptability to performances is high. The movable revolving stage can move horizontally or along a curve toward any direction and revolve by 360 degrees. According to requirements of users, the stage area can be preserved, the revolving angle can be preset, and therefore the customized moving and revolving effects of the stage can be achieved. The invention further provides a control method of the movable revolving stage. The control method is used for controlling changing and setting up of the stage, and operation is convenient and fast.

The invention provides a control method for a movable rotating stage, the steps of which include initializing the moving platform, adjusting the traveling direction of the omnidirectional wheel of the moving platform to be consistent with the direction of one of the center lines of the skeleton body of the moving platform, recording the movement The reading of the encoder attached to the platform; stage transformation planning, the main control board controls the walking path of the mobile platform according to the received path instructions, combined with the information collected by the encoder, and finally realizes stage transformation; used to control the above movable type The change and construction of the rotating stage is convenient and quick to operate.

Disclosed are a self-moving device and a fastening release method of a fastening mechanism of the self-moving device. The device comprises an outer frame and a base. The base is provided with a control unit and a traveling unit and also provided with the fastening mechanism (300). The fastening mechanism mainly comprises a pin assembly and a cam assembly. The fastening mechanism is provided with a signal trigger mechanism connected with the control unit, in a corresponding position. The control unit controls a cam in the cam assembly to rotate clockwise or anticlockwise, the pin assembly moves with the change in the height of a spiral slant of the cam such that the pin assembly runs in a released or locked position, and the signal trigger mechanism is triggered to output a signal to the control unit which controls the base to rotate relative to the outer frame according to the output signal; or the control unit drives the self-moving device to continue traveling. The self-moving device is simple in structure, the relative rotation of the base and the outer frame is effectively guaranteed, the accuracy for positioning and locking after rotation is provided, and a guarantee is provided for the forward direction of the self-moving device to be constantly perpendicular to a corresponding side of the outer frame of the device.

The invention discloses a rotary setting tool for a tubular column. The rotary setting tool for the tubular column comprises an upper joint provided with an internal thread, wherein the lower end of the upper joint is connected with a connecting body; the external side of the lower end of the connecting body is connected with a spring cylinder; the internal side of the lower end of the connecting body is connected with a spline shaft with an axial key slot; a spring, a thrust ball bearing and an inner sleeve are arranged between the spline shaft and the spring cylinder in sequence from top to bottom; the external side of the lower end of the inner sleeve is connected with an outer sleeve; the internal side of the lower end of the outer sleeve is connected with a spline body; the internal side of the lower end of the spline body is connected with a piston cylinder; a lower mandrel is fixedly arranged on the internal side of the piston cylinder through a shear pin; the external side of the lower mandrel is provided with an axial reversing track with an integrated structure; and a guide pin for fixing a guide seat is arranged in the reversing track. According to the invention, the risk of encountering resistance during setting the tubular column can be reduced, the time consumed due to encountering resistance during setting the tubular column is reduced so as to ensure that the tubular column can be smoothly set in place in drilling and completion operation, and the rotary setting tool for the tubular column is suitable for setting the tubular column in the drilling and completion operation.

The invention discloses stirring equipment for production of non-dangerous chemicals. The stirring equipment comprises a box body, a box cover, a second rotating shaft, a connecting mechanism installed on the inner surface of the second rotating shaft, an adjusting mechanism installed at the bottom end of the box body, and a shielding mechanism installed on the outer surface of the box body. The connecting mechanism comprises a first rotating shaft, the first rotating shaft is fixedly connected to the bottom end surface of the second rotating shaft, and a second limiting plate is arranged on the outer surface of the top end of the second rotating shaft. The stirring equipment has the beneficial effects as follows: a clamping block mounted on the outer surface of the first rotating shaft and a pressing head connected with the clamping block are designed, and the clamping block can be easily clamped by the pressing head; a pressing ring connected with the outer surface of the pressing head is designed, and the pressing head can be easily clamped into the clamping block; a second sliding rail connected with a sliding groove in the inner surface of the pressing ring is designed, and itis guaranteed that the pressing ring does not rotate; a second rotating block in threaded connection with the pressing ring is designed, and sliding of the pressing ring is facilitated; and a secondlimiting plate located at the top end of the inner surface of the second rotating block is designed, and the position of the second rotating block can be easily fixed.
