Description
Technical field
The utility model relate to any caliber penstock longitudinal seam welding after the correction operation that deforms of radian, especially relate to
And the removable penstock longitudinal joint means for correcting of one.
Background technology
At present, pressure steel pipe of hydropower station makes the installation quality that quality directly affects penstock, and penstock is installed
Hydropower Station Construction is divided into bright tubular type at home, embedded all with penstock, quality be installed and weigh whole Diversion system of hydropower station
The quality of construction quality, in domestic Hydroelectric Project Construction, typically carries out to steel pipe adjusting circle, school after penstock longitudinal seam welding completes
Just, more employing inner support ensures diameter of steel tube and radian.
For quickening penstock making progress to guarantee its installation progress, various caliber correcting modes emerge in an endless stream, and state
In typically uses when penstock makes installation inner support ensureing penstock circularity, but penstock inner support is understood very big
The increase activity duration and injury mother metal；Longitudinal joint radian convex, outer recessed correction such as appearance after penstock longitudinal seam welding construction
The problem of operation, is insurmountable in some engineering；If the problem of radian correction after not solving longitudinal seam welding, penstock
The problem that will occur misalignment, mismatch during installation, strong influence penstock installation quality, to power station diversion pressure steel tube
Stable operation bring great security risk, additionally penstock can reduce pressure steel when installing inner support when making greatly
Pipe speed of production, uses and The present invention reduces inner support fixing link, can carry out the correction construction of caliber radian.
Utility model content
In order to solve the problems referred to above that steel pipe vertical seam welding correction field exists, the utility model provides a kind of removable
Penstock longitudinal joint means for correcting.
Described device utilizes hydraulic jack externally applied forces, utilizes radian adjustment block to support penstock deformation position,
The principle being deformed by external force by unsettled penstock deformation position, by variant part bit correction to required radian, this reality
It is to be realized by below scheme by novel purpose:
A kind of removable penstock longitudinal joint means for correcting, including means for correcting body, hydraulic jack, balancing weight, arc
Degree adjustment block, termination connecting shaft, steel wire rope, fixed pulley group, described means for correcting body is arranged at the longitudinal joint deformation of penstock
Place；Described hydraulic jack and balancing weight are connected by steel wire rope, and described fixed pulley group is for the slip positioning of steel wire rope, described
Radian adjustment block is arranged on the hanging part of unsettled penstock；Described termination connecting shaft connects means for correcting body.
Preferably, described means for correcting body is welded by steel plate combination.
The utility model provides removable penstock longitudinal joint means for correcting, solves the pressure of any caliber, thickness of slab
Steel pipe rolls, organize circle, occur after longitudinal seam welding welding deformation thus cause radian problem not up to standard；This apparatus structure designs
Rationally, stable performance, easy and simple to handle；This plant running is steady, disposably completes penstock longitudinal seam welding position or other arcs
Circle, correct operation are adjusted in degree deformation position, need to correct not damaged at longitudinal joint deformation to steel pipe, save time, laborsaving, safe and efficient, environmental protection
Reusable；Removable, detachable and reuse, there is too big change, then radian control panel in tube coupling height, tube coupling diameter
Between, away from height also change accordingly, with adapt to tube coupling deformation adjust circle, correct radian needs.
Brief description
Fig. 1 is that the one that the present invention provides may move penstock longitudinal joint means for correcting schematic diagram；
In figure: 1-means for correcting body, 2-hydraulic jack, 3-steel wire rope, 4-balancing weight, 5-fixed pulley group, 6-termination
Connecting shaft, 7-radian adjustment block, 8-penstock.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed explanation is carried out to the utility model.
Described removable penstock longitudinal joint means for correcting is as it is shown in figure 1, be vertically installed on pressure by means for correcting body 1
At steel pipe 8 longitudinal joint deformation, then with sleeper by means for correcting body 1 firm supporting, make means for correcting originally by termination connecting shaft 6
Body 1 bottom is locked, clamping, after allowing hydraulic jack 2 reach arc deforming position by balancing weight 4 and steel wire rope 3, opens hydraulic pressure
, there is external force deformation after utilizing radian adjustment block 7 and deformation location contacts, then use radian plate measurement deflection in jack,
After reaching required deflection, close hydraulic jack 2.Described fixed pulley group 5 is for the slip positioning of steel wire rope 3.
Adjust balancing weight 4 again and steel wire rope 3 allows hydraulic jack 2 reach arc deforming position at next, by above step
Operation, till the correction of whole piece longitudinal seam welding deformation is qualified.
After last tube coupling radian is up to standard, removes termination connecting shaft 6, utilize crane gear by means for correcting body from pressure steel
Take out at pipe longitudinal joint；Carry out packing pressure steel pipe vertical seam or other position radians adjust circle, correction operation.
Penstock need to be adjusted circle, correction position to be positioned over penstock longitudinal joint correction dress by the technical solution of the utility model
Behind the effectively adjustment position put, locked after the termination connecting shaft of this bottom of device is installed, adjust the position of hydraulic jack, peace
Dress hydraulic jack on top raise the head radian adjust plectane；Open the travel switch of hydraulic jack, each feeding about 5mm, enter
Row radian plate is measured；When radian correction reaches requirement, feed-disabling；Take out top to raise the head tune plectane；Carry out other alignings,
After all radians are up to standard；Take out penstock, i.e. complete penstock longitudinal joint correcting process.
By the application of technique, one be use this device when penstock is made radian and every size obtain
Good guarantee；Two is to use this device to carry out penstock longitudinal joint correction not injure mother metal, improves when penstock makes
Man-hour, work efficiency etc., when penstock is installed, welding quality and total quality are significantly improved.
The above, only the utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that the utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
Should be as the criterion with the protection domain of claims.
