Description

Technical Field

[0001] The invention relates to a cylindrical support device, in particular to a cylindrical support device which is suitable for various diameters and can be adjusted to roll horizontally. Background Art

[0002] In the field of underwater unmanned submersible technology and unmanned aerial vehicle technology, due to the requirements of pressure resistance, navigation dynamics and aerodynamics, most of the shell shapes of the main equipment compartments are cylindrical. When the equipment is heavy and cannot be lifted and disassembled vertically, the equipment or the loading device of the equipment needs to maintain a horizontal posture and accurately dock with the cylindrical shell. At this time, the cylindrical shell needs to be rolled to avoid interference in the docking. The existing roll adjustment method is that the cylinder is placed on a bracket paved with wool felt. The bracket is generally arc-shaped to match the shape of the cylinder. After the cylinder is wrapped with a sling at the center of gravity, the crane is started for a small eccentric lifting. The eccentric lifting will cause the cylinder to rotate, and the arc-shaped bracket will limit the movement of the cylinder in other directions, so that the cylinder only rotates around the axis, thereby achieving the roll adjustment of the cylinder. The main principle of the method of adjusting the roll by crane lifting is to use a crane and a sling to provide an upward force. The gravity of the cylinder itself does not coincide with the force, thereby generating a rotational torque. During rotation, sliding friction occurs between the arc-shaped support frame and the cylinder. The wool felt can reduce friction and protect the surface of the cylinder while causing sliding friction.

[0003] However, this method requires the use of a crane to adjust the roll, which may cause the following problems:

[0004] (1) Since rotation needs to overcome static friction before it can transform into dynamic friction, and static friction is greater than dynamic friction, it will be difficult to control the rolling angle if the lifting force is too small and the rotation will be too large.

[0005] (ii) Under the rotational resistance of static friction, the crane applies an upward force, which will slightly affect the vertical position of the cylinder and affect the accuracy of observation of the docking situation;

[0006] (3) This method can only adjust a small angle each time the crane is raised. If the lifting continues, the cylinder will leave the support frame. Therefore, when the adjustment angle is large, multiple crane liftings are required, which is time-consuming.

[0007] (iv) The arc-shaped support frame can only be adapted to a cylinder of one diameter, and cylinders of different diameters require different support frames. Summary of the invention

[0035] The supported cylinder 1 is supported by three rubber rollers 25 mounted on the passive frames 2 and one rubber roller 25 mounted on the active frame 7. The cylinder 1 is rolled by turning the hand wheel 30 on the active frame 7.
