Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] It should be noted that if there are directional indications such as up, down, left, right, front, back, etc. in the embodiment of the present invention, the directional indications are only used to explain the position of each individual in a certain posture as shown in the attached figure. If the relative positional relationship, movement conditions, etc. between the components change, the directional indication will also change accordingly. ...

Abstract

The invention discloses a lifting system gear shaft torque monitoring device and a gear shaft. The device comprises torque transmission tubes, strain measurement tubes, measurement fiber bragg gratings, transmission optical fibers, a rotary connector, a demodulator and a terminal, the strain measurement tubes are connected between the two adjacent torque transmission tubes, the measurement fiber bragg gratings are attached to the outer walls of the strain measurement tubes, a connecting hole is formed in each strain measurement tube, one ends of the transmission optical fibers penetrate through the connecting holes to be connected with the measuring fiber bragg gratings, the other ends of the transmission optical fibers penetrate through the torque transmission tubes to be connected with the rotary connector, the rotary connector is in data connection with the demodulator, and the demodulator is in data connection with the terminal; and the outer diameter of the torque transmission tubes is more than the outer diameter of the strain measurement tubes. According to the scheme, the torque of the climbing gear shaft can be accurately detected in real time, so that whether loads borne by all transmission devices are balanced or not can be effectively reflected, overload caused by deformation or other reasons of individual lifting systems can be found in time, and accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of torque monitoring, in particular to a gear shaft torque monitoring device of a lifting system and a gear shaft. Background technique [0002] The jack-up platform is composed of platform main body, legs and lifting system. The main body of the platform moves up and down along the legs by means of the lifting system. The safe working height of the sea surface is to ensure that the legs of the platform will not sink when the platform encounters a storm. It is widely used in offshore operations. [0003] Rack-and-pinion lifting system is widely used in jack-up platforms at present, which has the characteristics of fast lifting speed and simple operation. However, due to the heavy weight of offshore lifting platforms, it is required that the load of each climbing gear shaft is roughly equal, otherwise the load will be large Under the long-term stress, the hoisting gear shaft will have a higher degree of fat...
