Abstract
The invention relates to a hydraulic pipe clamping pile operating platform, comprising a hydraulic pipe clamp, a reducing regulation filling block, a platform gallery and a hydraulic self-locking device. The hydraulic pipe clamp is an assembly used for mechanically connecting, blocking and fixing a pile slicing operating platform with a pile head and mainly comprises two fixtures and two hydraulic cylinders. The reducing regulation filling block is formed by two semi-circle annular steel blocks which are respectively lined in two fixtures of the pipe clamp and are fixed with the fixtures by virtue of four uniformly distributed counter bore bolts. The pipe clamp is directly contacted with the outer wall of a pile by virtue of the reducing regulation filling block, thus the pipe clamp is fixed with a pile together. The platform gallery is a welding operation operating plane of a hydraulic pile splicing operating platform, and the platform gallery is divided into two parts which are respectively fixed on the two fixtures. The hydraulic self-locking device is a protective device which ensures the hydraulic pile splicing operating platform to be blocked and fixed with the pile, and high pressure air spring principle is used for realizing automatic aftercompaction inside a hydraulic cylinder, so as to ensure the pipe clamp to tightly hold pile lining. The hydraulic self-locking device is composed of an aftercompaction oil tank, a high pressure gas tank and a corresponding pipeline.
Description
Technical field
This (invention) utility model belongs to a kind of innovation of hydraulic pressure pile extension device of field of ocean engineering.
Background technology
In the piling of ocean, for cannot disposable stake being lifted into the situation of water and take the piling of segmentation pile extension scheme, stake is made as to two sections in advance, after platform jacket is in place, first lifting first section of stake inserts pile protection cylinder and squeezes into sea bed, then lift second segment stake and make the stake tongue of its underpart insert first section of stake top, and be welded as a whole, then a clump of piles is driven into projected depth.For the ease of pile extension, need on the top of first section of stake, establish an operating platform as welding operation plane.Conventional process is at a temporary operating platform of first section of pile head welding; After pile extension completes, then cut off.The welding of this temporary operating platform and pile crown and cut off all cumbersomely, and need to have and support ship welding is provided and cuts off operation planar near pile crown, the more important thing is the disposable use of temporary operating platform, substantially there is no the value of recycling.
Summary of the invention
The object of the invention is: in order to overcome the shortcoming of traditional temporary operating platform, propose Simple hydraulic pipe clamp pile splicing operation platform scheme, this scheme realizes the mechanical connection of pile extension operating platform and pile crown with the form of hydraulic pressure pipe clamp the drawback of having avoided welding to bring.
The present invention solves its technical problem: hydraulic pipe clamp pile splicing operation platform regulates cushion block, platform gallery and hydraulic pressure self-locking device to form by hydraulic pressure pipe clamp, reducing.Hydraulic pressure pipe clamp is the assembly for pile extension operating platform and the fixing of pile crown mechanical connection, mainly by two jigs, two hydraulic cylinders, formed, two jigs are coupled as one and are formed pipe clamp agent structure by a bolt axle, and can make any folding of two jigs axis centered by bolt axle.Article two, hydraulic cylinder upper and lower two ends of pipe clamp outer wall that are placed in, the dowel bar hinge joint on cylinder body and a slice jig wherein; Dowel bar hinge joint on piston rod and another sheet jig.It is two semicircle annular blooms that serve as a contrast respectively in two jigs of pipe clamp that reducing regulates cushion block, by four uniform countersunk bolts and jig, is fixed together.Pipe clamp is to regulate cushion block directly to contact with stake outer wall by reducing, thereby is fixed together with stake.
By using the reducing of different-thickness instead, regulate cushion block, realize the hydraulic pressure pipe clamp that uses same size in certain stake diameter range, improved versatility, reduced integrated cost; Reducing regulates cushion block inner side can be processed as latticed matsurface, the friction factor between raising and stake outer wall, thus improved safety in utilization.Platform gallery is the weld job operation planar of hydraulic pressure pile extension operating platform, and platform gallery is divided into two parts and is individually fixed on two jigs.Hydraulic pressure self-locking device is to guarantee hydraulic pressure pile extension operating platform pipe clamp and the protective device that stake fixes, and is to utilize pressure-air air spring principle to realize to automatic compensation in hydraulic cylinder, guarantees that pipe clamp holds pile lining tightly.Hydraulic pressure self-locking device is comprised of ftercompction oil tank, high pressure gas holder and respective line.
The invention has the beneficial effects as follows: quick for installation, connect safe and reliablely, and can dismantle easily, reuse; By removable parts assembly, applicable to a clump of piles for different-diameter.

The specific embodiment
As shown in Figure 1, 2, hydraulic pressure pipe clamp 1 is the assembly for pile extension operating platform and the fixing of pile crown mechanical connection, mainly by two jigs 5, two hydraulic cylinders 6, formed, two jigs 5 are coupled as one and are formed hydraulic pressure pipe clamp 1 agent structure by a bolt axle 7, and can make any folding of axis centered by bolt axle 7 of two jigs 5.Article two, hydraulic cylinder 6 hydraulic pressure pipe clamp 1 upper and lower two ends of outer wall that are placed in, the dowel bar hinge joint on cylinder body and a slice jig 5 wherein; Dowel bar hinge joint on piston rod and another sheet jig 5.It is two semicircle annular blooms that serve as a contrast respectively in 1 two jigs 5 of hydraulic pressure pipe clamp that reducing regulates cushion block 2, by four uniform countersunk bolts 8 and jig 5, is fixed together.Hydraulic pressure pipe clamp 1 is directly to contact with stake outer wall by 2 of reducing spacers, thereby is fixed together with stake.Platform gallery 3 is weld job operation planars of hydraulic pressure pile extension operating platform, platform gallery 3 is divided into two parts and is individually fixed on two jigs 5, to partly prune because opening the overlapping gallery of hydraulic pressure pipe clamp 1, after hydraulic pressure pipe clamp 1 closure, without guardrail part, draw iron chains protection, blank part waist board prevents that personnel from dropping.
As shown in Figure 3, hydraulic pressure self-locking device 4 is to guarantee hydraulic pressure pile extension operating platform pipe clamp and the protective device that stake fixes, and is to utilize pressure-air air spring principle to realize to the interior automatic compensation of hydraulic cylinder 6, guarantees that hydraulic pressure pipe clamp 1 holds pile lining tightly.Hydraulic pressure self-locking device 4 is comprised of ftercompction oil tank 9, high pressure gas holder 10 and respective line.High pressure gas holder 10 respectively has high-pressure ball valve 11-a, a 11-b with the top of ftercompction oil tank 9, between two high-pressure ball valve 11-a, 11-b, by a high-pressure air pipe 12, connects; Ftercompction oil tank 9 bottoms also have a high-pressure ball valve 11-c, are connected in a high-pressure oil pipe 13 of high-pressure ball valve 11-c by threeway, are connected respectively with the piston rear end of two hydraulic cylinders 6.Interior approximately 2/3rds the space of ftercompction oil tank 9 is hydraulic oil 15, and its top and high pressure gas holder 10 UNICOMs are also all filled with high-pressure inert gas 14.When the pressure of high-pressure inert gas 14 is held pile lining tightly with hydraulic pressure pipe clamp 1, hydraulic cylinder 6 rear end oil pressure setting values are identical.When pipe clamp hydraulic cylinder 6 has micro-pressure leakage, high-pressure inert gas 14 is pressed into hydraulic cylinder 6 rear ends by the hydraulic oil in ftercompction oil tank 9 15, substantially keeps the oil pressure of hydraulic cylinder 6 rear ends near setting value.
