Description
Technical Field
The utility model relates to an electric power engineering especially indicates among the extra-high voltage direct current transmission engineering, the alignment equipment that the sleeve pipe carries out the alignment with the contact tube.
Background
In an extra-high voltage direct current transmission project, a wall bushing is used for supporting and insulating places where a transmission line needs to penetrate through a plate-shaped object and a wall-shaped object. The insulating property of the wall bushing is improved by using the conductive tube in the wall bushing. The conductive tube is required to have good flatness. However, the length of the conductive tube is very long, usually more than 6 meters, so that the conductive tube needs to be straightened in the processing process of the conductive tube. But because of its long length, the pipe diameter is great, and it is relatively difficult to solve the alignment.
Disclosure of Invention
The utility model aims to solve the technical problem that a make things convenient for alignment equipment of contact tube alignment is provided, simple structure, the alignment is convenient.
The technical scheme provided by the utility model is that the straightening equipment for the direct current transmission contact tube is characterized by comprising a long strip plate-shaped working platform, a portal frame is arranged across the working platform, a jack is arranged above the working platform, the jack can be arranged on the portal frame in a vertically displaceable manner, and a piston of the jack faces downwards; supporting blocks for supporting the conductive tubes are respectively arranged on the working platforms positioned at the two sides of the portal frame.
And a groove for placing the conductive tube is arranged on the supporting block.
The groove is of a V-shaped, U-shaped or circular arc structure.
And fixed supporting seats which can be adjusted up and down along the portal frame are arranged on two sides of the portal frame, and the jack is fixedly arranged on the fixed supporting seats.
The gantry support structure is characterized in that a plurality of groups of fixed blocks are correspondingly arranged on support columns on two sides of the gantry at intervals, protruding parts are respectively arranged on two sides of the upper end of each fixed support seat, and the protruding parts of the fixed support seats can be placed between the upper adjacent fixed blocks and the lower adjacent fixed blocks to be fixed. And limiting blocks for limiting the fixed supporting seat are respectively arranged between the portal frame and the two sides of the working platform.
The utility model discloses a conductive tube alignment equipment, simple structure, convenient to use. The straightening device can be suitable for straightening the conductive tubes or other tubular objects with different outer diameter structures.
Drawings
Fig. 1, the structure of the present invention is schematically illustrated.
Fig. 2 is a schematic structural diagram of the jack.
Detailed Description
To better understand the above technical solution, preferred embodiments are described in detail with reference to the drawings. See fig. 1 and 2, among others.
The straightening equipment comprises a long-strip-shaped plate-shaped working platform 1, and a portal frame 3 is arranged across the working platform. Supporting blocks 2 are respectively arranged on the working platforms on two sides of the portal frame 3, grooves are formed in the supporting blocks 2, the shape of each groove meets the requirement that a conductive tube is placed on the groove, and the grooves can be V, U circular arc structures. The supporting block 2 is movably arranged on the working platform, and the position of the supporting block 2 can be moved according to the requirement. In order to keep the support stability, the supporting block is generally made of steel, and the steel block is heavy, so that the stability is good.
The gantry is provided with a jack fixing and supporting seat 4, a plurality of groups of fixing blocks 5 are correspondingly arranged on the vertical supporting columns on two sides of the gantry at intervals, the fixing blocks 5 are welded on the vertical supporting columns on two sides of the gantry, and horizontal threaded holes (not shown) for screwing bolts in are formed in the fixing blocks 5. The upper end both sides of fixed bolster 4 are outside outstanding, and fixed bolster is through placing the protruding portion between the fixed block on the portal frame, then two outsides of fixed block and fixed bolster protruding portion set up rectangular plate washer respectively, then pass the screw hole of rectangular board and fixed block through the bolt, fix the rectangular board on the vertical support column both sides of portal frame, carry on spacingly to the both ends of fixed bolster, prevent that it from deviating from. When the position of the fixed supporting seat needs to be adjusted, the bolt is unscrewed, the long strip plate is removed, and the fixed supporting seat is placed between different fixing blocks to achieve the position adjustment of the fixed supporting seat.
The fixed support seat is of an inverted trapezoidal structure, and a jack 6 is fixedly mounted on the fixed support seat. The jack 6 is fixed on the fixed supporting seat through a flange 8, and a piston 9 of the jack extends out of the lower end face of the fixed supporting seat. The jack is an oil jack, is connected to an oil pressure control device (not shown), and provides a driving force to a jack piston through oil pressure control.
A limiting block 7 is arranged between the bottom of the inner sides of the guide rails on the two sides of the portal frame and the working platform and used for preventing the fixed supporting seat from damaging the conductive tube after the fixed supporting seat is lost due to accident control.
The working principle is as follows: firstly, paving a buffer pad on a groove of a supporting block, and then placing a conductive pipe in the groove of the supporting block. And then measuring by using a dial indicator, and when the position of the conductive tube causes the jitter range of the dial indicator measurement data to exceed the allowable range, determining that the conductive tube is bent at the position. Then the high point position of the bending of the conductive pipe is moved to the position below the jack piston. The jack is adjusted to the most proper position in advance by adjusting the position of the fixed supporting seat. And then controlling a piston of the jack to move downwards through an oil pressure control device to press down the bent part of the conductive tube, enabling the piston of the jack to downwards press the bent part to deform downwards, lifting the piston of the jack after pressing down once, measuring, controlling the piston of the jack to continuously press down according to a measured value if the piston of the jack is not aligned in place after pressing down once, and performing blank pressing measurement until the straightness of the conductive tube meets the requirements of customers.
The straightening equipment has the advantages of simple structure, low manufacturing cost and convenient use. Because the extension length range of the piston end of the jack is limited, the conductive tubes with different diameters and sizes can be straightened by adjusting the position of the jack and the height position of the supporting block.
