The invention provides a spiral detaching drawing device. The spiral detaching drawing device is used for detaching a component with a head part and a main body connected in a threaded mode. The spiral detaching drawing device comprises a clamping working platform, a spiral detaching mechanism, pressing springs, a main shaft and a drawing mechanism; the spiral detaching mechanism comprises a spiral detaching seat located on one side of the clamping working platform and a plurality of clamping jaws arranged in the spiral detaching seta; the pressing springs are arranged between the clamping jaws and the spiral detaching seat; one end of the main shaft is connected with the spiral detaching seat, and the main shaft is connected with a rotating power mechanism; and the drawing mechanism comprises a plurality of drawing jaws connected with the other end of the main shaft and a straight line power mechanism connected with the drawing jaws. According to the spiral detaching drawing device, the clamping working platform is used for clamping the main body, the clamping jaws are used for clamping the head part, and the main shaft is driven by the rotating power mechanism and can drive the spiral detaching seat and the clamping jaws to rotate to enable the head part to be screwed out from the main body; the drawing jaws are driven by the straight line power mechanism, can pull the main shaft to axially move and drive the spiral detaching seat and the clamping jaws to move and finally enable the head part to be separated from the main body; and in the detaching process, the clamping jaws always clamp the head part and limit the radial movement of the head part, and the detaching process is reliable and stable.

The invention discloses a burner with low noise and high firepower, comprising a cylindrical outer shell and a cylindrical inner shell, the inner shell is sleeved in the outer shell, the top of the outer shell and the top of the inner shell are closed and connected, and a sandwich is formed between the outer shell and the inner shell Cavity, the bottom of the outer shell is provided with an air inlet, the bottom of the inner shell is sealed, and the inner cavity of the inner shell is set into at least two or more steps that expand step by step from bottom to top. All have ventilation holes throughout. The air blown out of the bottom cavity is ejected from the space corresponding to the cavity of the corresponding layer, and the air blown out of each upper cavity can be ejected from the space corresponding to the expansion of the corresponding stage, so that the airflows of different heights are sprayed out. Compared with the traditional one, the collision and pushing of the air conditioner are greatly weakened, which can effectively reduce the turbulence phenomenon, and the offset of the jetting force between the different heights of the air flow to the outside of the burner will also be effectively weakened.

The invention provides a unscrewing and pulling device, which is used to remove the components connected by the head and the main body in a threaded manner, including: a clamping worktable; a unscrewing mechanism, including a unscrewing seat located on one side of the clamping workbench, And a plurality of jaws arranged in the unscrewing seat; a compression spring is arranged between the jaws and the unscrewing seat; one end of the main shaft is connected with the unscrewing seat, and a rotating power mechanism is connected; the pulling mechanism includes another connection with the main shaft A plurality of pulling claws connected at one end, and a linear power mechanism connected with the pulling claws. In the unscrewing and drawing device provided by the present invention, the clamping table is used to clamp the main body, the jaws are used to clamp the head, and the main shaft can drive the unscrewing seat and the jaws to rotate under the drive of the rotating power mechanism, so that the head The head is unscrewed from the main body; the pull claw can pull the main shaft to move axially under the drive of the linear power mechanism, and drive the unscrewing seat and the jaw to move, and finally the head is separated from the main body; during the removal process, the jaw always clamps the head , the radial movement of the head is limited, and the removal process is reliable and stable.

The invention provides an engine limit load control method and device. The engine limit load control method includes the steps of obtaining the current rotating speed of an engine, obtaining a rotating speed / torque relation graph of the engine, dividing the rotating speed / torque relation graph into multiple areas according to the rotating speeds, using a straight line section to connect a start point of each area with the end point of the area to obtain a rotating speed / torque relation curve of the engine, obtaining the largest output torque corresponding to the current rotating speed according to the rotating speed / torque relation curve, and controlling the torque consumed by a hydraulic system driven by the engine to be always smaller than the largest output torque. The largest output torque which can be supplied by the engine at some moment can be obtained in real time, meanwhile, the size of the torque consumed by the hydraulic system is controlled, and therefore the torque can be always smaller than the largest output torque which can be outputted by the engine, so that the engine can supply enough power for the hydraulic system, and the hydraulic system can not be shut down under various working conditions.
