Heavy load salvage wave compensation system of super large floating crane

InactiveCN101780923ASolve the problem of impact forceLanding safetyCranesMarine engineeringEddy current
The invention relates to a heavy load salvage wave compensation system of a super large floating crane, which comprises a mechanical system, a hydraulic system, a monitor system, control of a hydraulic oil cylinder, control of an accumulator and the like, wherein the mechanical system consists of a lifting drum, a plurality of sets of pulley, a steel wire rope and a large tonnage lifting hook, the hydraulic system consists of an oil cylinder, the accumulator, the hydraulic oil cylinder and a hydraulic valve, and the monitor system consists of a floating crane body displacement monitor, a floating crane ship body displacement monitor and a floating crane lifting heavy weight displacement monitor. The invention solves the problems that when the super large floating crane carries out heavy load salvage, and at the moment that a heavy weight is lifted out of water, because the heavy weight has large volume, seawater forms an eddy current to enable a floating crane ship body to be inclined and swing, and a lifting weight also swings along with the floating crane ship body and can not be controlled, solves the problems that when a large structure is lifted on the sea, waves influence the floating crane ship body to lead to difficult butting of marine platforms to ensure goods to be safely fall on a ship deck or safe offshore platform installation and allows that the ship has certain inclination to be suitable for tough working conditions of marine operation.

Stereoscopic garage

ActiveCN103184805AThere will be no phenomenon of bumping the pillars of the carriageReduce swingParkingsWindlassWinch
The invention discloses a stereoscopic garage. The stereoscopic garage is characterized in that four windlasses of a winch are driven to rotate by using a winch motor, and simultaneously four steel wire ropes are simultaneously wound and released, so that a lift car cannot rotate at random; a carriage is connected with a top seat of the lift car through a horizontal rotating device of the carriage, which is arranged below the top seat of the lift car; therefore, when the carriage rotates, a car carrying device arranged on a carriage base rotates together with the carriage, and the phenomenon that the car carrying device bumps a carriage pillar is avoided; when a trolley or a large vehicle for lifting or transversely moving the stereoscopic garage is started or stopped, the lift car swings due to the inertia of the lift car; and an axial flow fan of an inertia damping device of the lift car can be used for reducing the swing amplitude of the lift car. The car carrying device in the stereoscopic garage is formed by using a horizontal moving motor for driving walking wheel gears to rotate on walking racks, thus a mounting bracket and a supporting plate are driven to move horizontally; and a hydraulic jack on the mounting bracket is used for putting a car on the supporting plate on garage steps. As the center of gravity of the carriage is biased after the car is put on the supporting plate, the biased center of gravity can be adjusted by a center-of-gravity adjusting device.

Floating type brake pad

The invention discloses a floating type brake pad. The floating type brake pad comprises a back plate, a plurality of friction blocks, disc springs and clamping springs, wherein the friction blocks are arranged on the back plate, the disc springs are arranged between the friction blocks and the back plate, and the friction blocks are connected to the first back plate in a floating mode through the clamping springs. Positioning grooves are formed in the back plate, and the disc springs are arranged inside the positioning grooves. The back plate is divided into a plurality of concentric circular rings by using the circle center of a brake disc matched with the brake pad as the circle center. The circular rings are equal in radial length. The friction area of the friction block inside each circular ring is not larger than 15% of the standard average friction area compared with the standard average friction area. According to the floating type brake pad, the problem of fatigue cracks caused by instantaneous stress concentration during braking of existing disc springs is solved, meanwhile, gaps between the back plate and the friction blocks are reduced, oscillation of the friction blocks is small, meanwhile, the problem of eccentric abrasion of the friction blocks is avoided, and the brake stability is greatly improved.
