Abstract

A crane hanger of ocean platform relates to a crane hanger. A clamper for settling the problems in a discharge pipe system of ocean platform has the following problems: incapacity for adjusting the balance in clamping the pipes, low operation efficiency, and incapacity for ensuring the safety of construction field. A hydraulic motor rotates as a power source driving reducer of a reducer. An output shaft of the reducer is fixedly provided with a gear which is engaged with an outer tooth ring type rotary bearing. The outer tooth ring type rotary bearing is equipped on a clamper body. The clamper body is driven to rotate through the rotation of the outer tooth ring type rotary bearing. A crossbeam of the clamper body slides on a groove type track through the telescoping of the first hydraulic cylinder. Clamping paws are closed through the driving of a corresponding third hydraulic cylinder. The third hydraulic cylinder is connected with the clamper body. A spacing block of the spacing mechanism performs spacing through the telescoping of the second hydraulic cylinder. The first hydraulic cylinder and the second hydraulic cylinder are connected with the clamper body. The crane hanger of ocean platform is used for clamping the pipes on ocean platform.

The specific embodiment

The specific embodiment one: in conjunction with Fig. 1-Fig. 7 explanation, the ocean platform loop wheel machine suspender (clamper) of present embodiment is made up of clamp body 1, rotating mechanism, balance control mechanism and clamping position-limit mechanism; Rotating mechanism is made up of hydraulic motor 2, reducer 3, gear 4, external toothing type floating bearing 6, hydraulic motor 2 rotates as the drive power source reducer 3 of reducer 3, be fixed with gear 4 on the output shaft of reducer 3,

gear

4 and 6 engagements of external toothing type floating bearing, external toothing type floating bearing 6 is contained on the clamp body 1, rotates by the rotation drive clamp body 1 of external toothing type floating bearing 6; Balance control mechanism is made up of first hydraulic cylinder 7 and two groups of grooved tracks 8, two groups of grooved tracks 8 are set in parallel on the clamp body 1, the crossbeam 9 of clamp body 1 slides on two groups of grooved tracks 8 by stretching of first hydraulic cylinder 7, and first hydraulic cylinder 7 is connected with clamp body 1; The clamping position-limit mechanism is by two gripper jaws 14, two the 3rd hydraulic cylinders 10, two second hydraulic cylinders 11 and two position-limit mechanisms 12 are formed, two gripper jaws 14 are set up in parallel along the width of the crossbeam 9 of clamp body 1, the fixed claw 15 of each gripper jaw 14 is connected with clamp body 1, the movable claw 16 of each gripper jaw 14 is by driving and this fixed claw 15 closures of corresponding the 3rd hydraulic cylinder 10, the 3rd hydraulic cylinder 10 is connected with clamp body 1, two gripper jaws 14 each side be provided with a position-limit mechanism 12, the limited block 13 of each position-limit mechanism 12 is flexible spacing by corresponding second hydraulic cylinder 11, and second hydraulic cylinder 11 is connected with clamp body 1.

The specific embodiment two: in conjunction with Fig. 1 present embodiment is described, the scope that horizontally rotates of the clamp body 1 of present embodiment is-90 degree ~+90 degree.Other is identical with the specific embodiment one.

The function of rotating mechanism: rotating mechanism is rotated by hydraulic motor band reducer driven wheel, and by the engagement of gear and external toothing type floating bearing external toothing type floating bearing is rotated, thereby reaches the integrally rotated purpose of clamp body.

The function of balance control mechanism: can keep the center of gravity of the pipe of clamping can not produce excessive offset distance by balance control mechanism, when clamping pipe centre-of gravity shift, by stretching of first hydraulic cylinder, the crossbeam of clamp body is slided in the grooved track, thereby center of gravity has been carried out corresponding adjustment, make whole clamper remain on dynamic equilibrium state, can not produce potential safety hazard.
