Description
Technical field
The present invention relates to technique of pipe field, a kind of rising for steel pipe protecting ring attaches together the device joined.
Background technology
Patent publication No. CN 103447810A, the Chinese invention patent of publication date 2013.12.18 discloses a kind of steel for moulding protection of pipe ring in the steel tube end part tensioner of sleeve pipe and moulds pipe pipe end protection ring tensioner assembly machine, including total support, the steel tube fixing clamp tool being arranged on total support and swelling device, described swelling device includes guide seats and is arranged at the tension mechanism moving ahead on base, the axis of guide of horizontally set it is provided with in described guide seats, described tension mechanism includes slide and the harmomegathus frame being arranged on slide and the tensioner parts being arranged on tensioner frame being set up on the axis of guide and can sliding along the axis of guide.Tensioner parts include expansion shaft, harmomegathus axle sleeve and tensioner head; harmomegathus head includes the inner slide being arranged at power transmission shaft front end and outer slide that is that be buckled on inner slide and that can radially slide; steel pipe is fixed by this assembly machine by steel tube fixing clamp tool, then steel tube end part is moulded protection of pipe ring is carried out tensioner by swelling device.
But; actual work we have found that; existing tensioner assembly machine; its volume is big, it is big to take up room, mobile difficulty, it is adaptable to large-scale production and application in factory, and in pipeline carries out process of deployment and in maintenance process; it is frequently encountered steel pipe to need to carry out protection ring assembling; and this time can only be to be transported back by steel pipe after factory assembles again now, it is being shipped back building site, is being inconvenient for.
Summary of the invention
In place of it is an object of the invention to provide for the deficiencies in the prior art, it is provided that a kind of portable steel is moulded pipe pipe end protection ring and risen locking device, its simple in construction, be easy to carry, volume is little, lightweight, processing ease, easy to maintenance, maintainability performance is good.
In order to solve above-mentioned technical problem, technical scheme is as follows: portable steel is moulded pipe pipe end protection ring and risen locking device, fixes straight line driving mechanism and and the tapered portion that connects of described straight line driving mechanism of connection including shell body and described shell body；Described shell body is provided with installation pipe in the end away from described straight line driving mechanism, and described installation pipe is provided with conjunction portion of rising；Described conjunction portion of rising includes wedge portions and is sleeved on the flexible fastening set on described wedge portions outer circumference surface, described wedge portions includes multiple voussoir, uniform multiple sockets communicated with its endoporus on described installation pipe outer circumference surface, multiple described voussoirs are plugged in described socket, and integral by described flexible fastening set constraint.
The applicant finds in production practices; at the construction field (site); often there is the demand temporarily carrying out protection ring tensioner; and present way is typically to transport steel pipe back factory and carries out tensioner, the most cumbersome, and be also easy to cause steel pipe to damage during carrying; for this; existing protection ring assembly machine is improved by we, it is preferred that emphasis is is easy to carry, dismantles and installs so that its structure is the simplest, compact, lightweight；nullThus had the technical scheme of the application，In the application，Voussoir is plugged in socket，Flexible fastening set is utilized to be held onto by multiple voussoirs，It is made to become an entirety，This structure is the simplest，Secondly，It is highly convenient for dismounting and installs，The when of needing dismounting，By flexible fastening set removal (because it has elasticity，So it is the most readily accessible、Install，Easily replace)，The most just voussoir is extracted from socket，Dismounting can be completed within the shortest time，It is replaced easily or keeps in repair，After completing maintenance or changing，Again flexible fastening set is loaded onto，Just can work，Between flexible fastening set and voussoir，The parts the most not connected，Between voussoir and installation pipe，Both are not the most made to connect fixing parts，Greatly simplify structure，And flexible fastening set is not only able to play the effect of constraint voussoir，Work when，It provides the power resetted can also to the voussoir stretched out，The more important thing is，During carrying out tube，It is limited to machining accuracy、The reasons such as cost，Between circularity and the circularity of protection ring of steel tube inner hole to be processed，There is difference，And utilize flexible fastening set can make up this difference，Protection ring can preferably be fitted with steel tube inner hole，Ensure tensioner effect.
As preferably, the outer circumference surface of described installation pipe is continuous cylinder face or the spaced face of cylinder or regular polygon surface or taper seat or spaced taper seat continuously.
