Abstract
The present invention provides a mechanical self-locking spud leg mounting rack device, which comprises an upper hoop, a lower hoop, a circumferential tension bolt, an upper pawl, a lower pawl, an axial tension screw, and an operating platform. The way of forming self-locking is as follows: frapping the circumferential tension bolt to block the upper hoop and the lower hoop onto the spud leg, thus forming one rub self-locking; and clamping the spud leg by the upper pawl and the lower pawl through the axial tension screw, thus forming self-locking again. The whole device can move freely along the spud leg after the circumferential tension bolt and the axial tension screw are loosened. After the circumferential tension bolt and the axial tension screw are frapped, the friction is larger when the external force is larger, therefore the clamping unit is fixed on the spud leg. Bidirectional and dual friction self-locking can be realized by using the present invention.
Description
Technical field
The present invention relates to a kind of mechanical device of ocean platform spud leg installing rack, especially a kind of mechanical self-latching type installing rack device that is used for fixing the installation of formula ocean platform spud leg.
Background technology
Oil field, shallow sea, the beach ocean platform that usage quantity is maximum on stream in China Bohai Sea Gulf is a jacket platform, and this platform comprises jacket, spud leg and upper module.Each several part carry out on land prefabricated after, lifting migrates to the sea and installs again.Wherein drive piles behind the handling and securing after upending procedure, in the piling process, need one section one section ground of spud leg is welded.Need an installing rack when two sections spud legs manually weld, existing method is to make an interim installing rack by welding manner around spud leg, cuts after finishing using again.Existing this interim installing rack uses inconvenient, nor safety.
Summary of the invention
Defective at above-mentioned prior art existence, the object of the present invention is to provide a kind of mechanical self-latching type device that is used for fixing formula ocean platform spud leg installing rack, this device is according to the mechanical friction principle, can effectively stop the installing rack device along spud leg moving of direction up and down, thereby the realization bidirectional self-locking is for the installation of coastal waters fixed offshore platform provides a kind of convenience, safe, economic installing rack device.
For achieving the above object, the invention provides a kind of can be along the spud leg free lifting, and can realize the mechanical self-latching type spud leg installing rack device of friction self-locking in any position, comprise hoop, go up ratchet, axially stretching screw, hoop, following ratchet, spud leg, hoop turnbuckle, studdle down.Last hoop, following hoop are stuck in by the hoop turnbuckle earlier and form self-locking on the spud leg; Make ratchet and following ratchet chucking spud leg by axial stretching screw again, form two-way, double rub self-locking.To guarantee that device can not move along spud leg.
Wherein: the contact site of going up ratchet and following ratchet and spud leg is tooth type structures, and carries out case hardening and handle; The described ratchet of going up is an eccentric structure with following ratchet, last ratchet and following ratchet are symmetry and install, the load of being got off by the operating platform transmission is big more, and the self-locking frictional force that then goes up ratchet, following ratchet and axial stretching screw formation is also big more, makes device and spud leg relative fixed tight more; Last hoop is equipped with studdle with following hoop, and studdle is a stainless steel; Studdle has 3, and is the hexagonal angle distribution mutually; Be drilled with the screw that matches with studdle on last hoop and the following hoop, and hoop and following hoop (4) on the up/down perforation; Thread rotary orientation on last hoop and the following hoop is opposite, with the convenient spacing that goes up hoop and following hoop of regulating.
Advantage of the present invention: the mechanical self-latching type spud leg installing rack device that provides, in ocean platform spud leg welding implementation process, can constantly be reused.The welding and the cutting construction process of existing installing rack have been avoided, compare with existing installing rack, have simple in structure, safe and reliable, flexible operation, advantage such as convenient and swift, cheap, economical and practical, and greatly improved the installation effectiveness of ocean platform, in the ocean platform installing engineering, had broad application prospects.

The specific embodiment
As Figure 1-3, the present invention includes hoop 1, go up ratchet 2, axially stretching screw 3, down hoop 4, ratchet 5, spud leg 6, hoop turnbuckle 7, studdle 8 constitute down.At first, will go up hoop 1 and following hoop 4 and be stuck on the spud leg 6 by hoop adjustment bolt 7 respectively, will go up that hoop 1 and following hoop 4 are asymmetric to be drawn mutually, form two-way friction self-locking; Secondly, an end of last hoop 1 links to each other with last ratchet 2, and an end of following hoop 4 links to each other with following ratchet 5, and external force is acted on ratchet 2 and following ratchet 5, and ratchet 2 and following ratchet 5 are stuck on the spud leg, forms friction self-locking once more.In a word, two hoops and two ratchets tighten up by axial stretching screw, form dual, bi-directional friction self-locking, can not move along spud leg to guarantee device.
Wherein: the contact site of going up ratchet 2 and following ratchet 5 and spud leg 6 is tooth type structures, and carries out the case hardening processing, skids preventing; The described ratchet 2 of going up is an eccentric structure with following ratchet 5, last ratchet 2 and following ratchet 5 are symmetry and install, the load of being got off by the operating platform transmission is big more, and the self-locking frictional force that then goes up ratchet 2, following ratchet 5 and axial stretching screw 3 formation is also big more, makes device relative with spud leg solid tight more; Last hoop 1 is equipped with studdle 8 with following hoop 4, the power that provides support when locking for axial stretching screw 3, and studdle 8 is a stainless steel; Studdle 8 has 3, and is the hexagonal angle distribution mutually; Last hoop 1 is drilled with the screw that matches with studdle 8 with following hoop 4, and hoop 1 and following hoop 4 on the up/down perforation; Thread rotary orientation on last hoop 1 and the following hoop 4 is opposite, with the convenient spacing that goes up hoop 1 and following hoop 4 of regulating.
In use, platform with the workman is installed on this device earlier, afterwards can be according to diverse location or lifting apparatus of the present invention highly at any time of spud leg welding, concrete operations are as follows: loosen hoop and adjust bolt 7 and axial stretching screw 3, can move freely along spud leg by implement device, by tightening ring to adjusting bolt 7 and axial stretching screw 3, can implement device in any fixed-site of spud leg.
