[0016] The driving method of the rotary spreader includes the following steps:

[0017] S1. Drive the rotating motor to drive the rotating gear to rotate and mesh with the teeth, causing the C-type spreader to rotate. The equipment clamped inside the C-type spreader rotates synchronously with the C-type spreader. When the C-type spreader rotates, it rotates above the guide wheel. The guide wheel is used to lift and guide the C-type spreader to prevent it from tilting.

[0018] S2. Place the equipment to be suspended inside the two C-shaped slings, drive the lifting motor to rotate the active bevel gear and engage it with the driven bevel gear, so that the driven bevel gear drives the transmission rod and the take-up pulley to rotate. The belt is wound or unwound by the rotation of the take-up pulley. At this time, the belt drives the lower frame to rise and fall, and the lower frame also drives the C-shaped sling and the equipment inside the C-shaped sling to rise and fall. As the lower frame rises and falls, the lifting parts 1 and 2 will perform a scissor-like folding action, and the slider will slide inside the slide seat to guide the top end of the lifting part 1 and the bottom end of the lifting part 2.

[0019] S3. Drive the travel motor to drive the travel wheels to rotate and roll on the travel guide seat, which can drive the travel guide seat to move together with the upper frame, scissor-type lifting frame, lower frame, support frame and C-type spreader. The equipment inside the C-type spreader moves synchronously with the C-type spreader.

[0020] In the above technical solution, the rotary spreader provided by the utility model,

[0021] 1. Through the C-type spreader, guide wheel, teeth, rotating motor, rotating gear and load-bearing support arm, the rotating motor drives the rotating gear to rotate and mesh with the teeth, so that the teeth can drive the C-type spreader to rotate, and then the equipment hoisted inside the C-type spreader can be rotated, which is convenient for maintenance of the bottom of the equipment. There is no need for maintenance workers to look up for a long time, which solves the problem of looking up for maintenance of the bottom of the equipment. It is very easy to get tired when standing in the posture for a long time, and the problem of needing to rest after maintenance for a period of time is improved, thereby improving the efficiency of maintenance. When the C-type spreader rotates, it rotates on the fitting guide wheel. The guide wheel can support the C-type spreader on the one hand, and assist the rotation of the C-type spreader on the other hand, making the rotation of the C-type spreader more labor-saving;

[0022] 2. Through the sliding seat, sliding block, lifting member, lifting member 1, lifting member 2, rotating seat, transmission box, transmission rod, take-up pulley, driven bevel gear, lifting motor, active bevel gear, hanging seat and belt, the lifting motor drives the active bevel gear to rotate, the active bevel gear drives the transmission rod to rotate by meshing with the driven bevel gear, and the transmission rod drives the take-up pulley to rotate to reel or unreel the belt. When the belt is reeled, the belt can drive the lower frame, support frame and C-type spreader to rise. When the pulley is unreeled, the belt can drive the lower frame, support frame and C-type spreader to descend. The height of the C-type spreader can be adjusted, and the equipment hoisted inside the C-type spreader can be raised or lowered.

[0023] 3. Through the travel guide seat, travel motor, travel wheel and guide rail, the travel motor can drive the travel to rotate and travel on the guide rail, and then the travel guide seat can move on the guide rail. When the travel guide seat moves, it will drive the scissor-type lifting frame, lower frame, support frame, C-type spreader and the equipment hoisted inside the C-type spreader to move, making the spreader a spreader that can rotate, lift and move in one, and a multifunctional spreader.
