Abstract
The utility model provides a harmless group of pressure steel pipe longitudinal joint is to device, includes balance beam, and balance beam's web one end is equipped with the hook, and the connecting plate matched with screw with the bottom hook is seted up to balance beam's the web other end, and the connecting plate of bottom hook is for " pi " template and seted up and gone up screw matched with screw with balance beam, and bottom hook and balance beam pass through the bolt spiro union and form the hook at the portal frame of circle longitudinal joint department of pressure steel pipe group, and the wedge board cooperatees with pressure steel pipe group circle longitudinal joint. The utility model provides a harmless group of pressure steel pipe longitudinal joint is to device can solve the problem that leads to the fact easily the damage to the pipe wall, has avoided from this the damage that leads to the fact the mother metal, satisfies harmless group that pressure steel pipe made the longitudinal joint to requiring.
Description
Technical field
This utility model is related to hydroelectric project penstock installing area, especially a kind of penstock longitudinal joint lossless group pair
Device.
Background technology
At present, the general side using welding equipment pressure code, cooperation wedge tooled joint on tube wall of hydroelectric project penstock manufacture
Formula carries out inevitably tube wall being caused when longitudinal joint group pair, welding equipment and dismounting pressure code damage.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of lossless group of penstock longitudinal joint to device, can solve
Certainly easily cause to tube wall the problem damaged, it is to avoid the damage that thus causes to mother metal, meet penstock manufacture longitudinal joint
Lossless group to requiring.
To solve above-mentioned technical problem, the technical scheme that this utility model is adopted is：A kind of penstock longitudinal joint is lossless
Group is to device, including shoulder pole girder, and web one end of shoulder pole girder is provided with hook, and the web other end of shoulder pole girder is offered and lower hook
The screw that connecting plate is engaged, the connecting plate of lower hook is " Π " template and offers the screw being engaged with screw on shoulder pole girder,
Lower hook is spirally connected to form the portal frame being hooked at penstock group circle longitudinal joint, wedge and penstock with shoulder pole girder by bolt
Group circle longitudinal joint is engaged.
Shoulder pole girder is the shoulder pole girder of T-shape structure.
The web of shoulder pole girder is provided with one end of hook and is further opened with lifting hole(eyelet).
Lossless group of the penstock longitudinal joint that this utility model is provided to device, by connecting bolt by lower hook and shoulder pole girder spiral shell
Connect to form the portal frame being hooked at penstock group circle longitudinal joint, in penstock longitudinal joint group at mismatch between portal frame and wallboard
Gap squeezes into wedge and carries out mismatch amount adjustment, you can realize lossless group pair, without the need for the welding equipment on tube wall and dismounting pressure code, it is to avoid
Thus the damage for causing to mother metal, while also reducing cost, improve product quality, is particularly suitable for application to high-strength steel pressure
Steel pipe manufacture requirements longitudinal joint group is to damaging situation during mother metal.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is described in further detail：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the I-I of this utility model Fig. 1 to sectional view.
Specific embodiment
As depicted in figs. 1 and 2, a kind of lossless group of penstock longitudinal joint is to device, including shoulder pole girder 1, the web of shoulder pole girder 1
1-1 one end is provided with hook 1-2, and the web 1-1 other ends of shoulder pole girder 1 offer the spiral shell being engaged with the connecting plate 2-1 of lower hook 2
Hole, the connecting plate 2-1 of lower hook 2 is " Π " template and offers the screw being engaged with screw on shoulder pole girder 1, lower hook 2 and shoulder pole
Beam 1 is spirally connected to form the portal frame being hooked at 5 groups of circle longitudinal joints of penstock by bolt 3, wedge 4 and 5 groups of circles of penstock
Longitudinal joint is engaged.
Shoulder pole girder 1 is the shoulder pole girder of T-shape structure.
The web 1-1 of shoulder pole girder 1 is provided with one end of hook 1-2 and is further opened with lifting hole(eyelet) 1-3.
Use process of the present utility model is as follows：
When using, shoulder pole girder 1 is hooked on into the group circle docking longitudinal joint upper end symmetrical center positions of penstock 5, lower hook 2
The web 1-1 of shoulder pole girder 1 is stuck in " Π " template into centre and hook is stuck in penstock group circle docking longitudinal joint lower end, by connecting spiral shell
The web 1-1 of lower hook 2 and shoulder pole girder 1 is spirally connected to form portal frame by bolt 3.Portal frame at mismatch and wallboard gap are beaten in longitudinal joint group
Enter the adjustment mismatch amount of wedge 4, to tack welding is carried out at dorsal suture after qualified, lossless group of the longitudinal joint is to complete for whole piece longitudinal joint group
Into.
