Abstract
The invention relates to an internally clamping pipe hanger device, which mainly comprises a shell 8, a wedge block 6, a cone push rod 5, a friction block 7 and a high-pressure hydraulic cylinder 4. Firstly the pipe hanger device is horizontally lifted by a crane through a horizontal lifting point and is inserted in a lifting pile pipe by a guide plate of the device; the hydraulic cylinder pushes the cone push rod to move axially and drives the wedge block to move radially so as to make a jagged friction block nipped into the inner wall of the pile pipe; and the pipe is lifted by the friction force generated when the friction block is in contact with the inner wall of the pipe. The invention has the advantages of completely replacing the work of welding and cutting a lifting lug in the piling construction, also reducing the consumption of working time and materials and further improving the constructing speed of offshore piling.
Description
Technical field
The invention belongs to the innovation of the hanging apparatus of ocean engineering piling construction process.
Background technology
At present, in the piling project, be in plumbness for a pipe is erected, and the stake pipe vertically be inserted in the stake pipe knock hole of structure.Common construction method is to weld hanger in advance on the stake pipe, in the opportune moment of work progress, hanger is excised.There is the problem that consumes more man-hour and material in this kind method.
Summary of the invention
In order to shorten the marine installation period of platform structure, and the reduction expense, the invention provides a kind of internally clamping pipe hanger device.This device be because simple structure, characteristics such as easy to use can replace the work of welding hanger and excision hanger fully, reduces work hours simultaneously and the consumption of material, further improves the speed of application of marine guidance piling.
The technical solution adopted for the present invention to solve the technical problems is: this device is made up of working portion and power pack section, and wherein working portion mainly is made up of housing, wedge, cone push rod, friction shoe, high pressure liquid cylinder pressure; Power pack section mainly is made up of high voltage power station, storage pipe winch, and wherein storage pipe winch adopts centre revolving joint to be connected with the high voltage power station, and winch adopts motorized motions.The groundwork process is, at first the swing pipe device is sling by horizontal suspension centre level by loop wheel machine, guide plate by device is inserted in the lifting stake pipe, discharge the lifting appliance high-pressure rubber pipe, be tiled between power station and the stake pipe, start swing pipe device power station, reach nominal working pressure, cylinder pushes cone push rod axial motion, drive the wedge radial motion, thereby make to have zigzag friction shoe and bite into an inside pipe wall, the friction force that contacts with tube wall by the friction shoe pipe of slinging, wherein friction shoe can be changed according to the difference of caliber.The loop wheel machine suspension centre is changed to the vertical suspension centre of swing pipe device, then steel pipe is sling at a slow speed equably, deliver to the installation site.Operation pressure, working flow that the engine installation generator needs, storage work high pressure fuel pipe.
The friction shoe surface is a serration in the above-mentioned internally clamping pipe hanger device, material selection 65Mn steel, and quenching increases friction shoe hardness and intensity.
Wedge material selection 40Cr in the above-mentioned internally clamping pipe hanger device is through heat treatment increase its toughness, plasticity and resistance to abrasion.
The use that the invention has the beneficial effects as follows internally clamping pipe hanger has replaced the work of the welding hanger in the piling work, excision hanger, further improves the speed of application of piling, shortens offshore construction duration and reduction expense.This device can be applied to the pipe of the caliber of certain limit, has increased the degree of utilization of this device to a certain extent.
