Summary of the invention
The purpose of this utility model is to provide a kind of attaching/detaching apparatus of heat exchanger thread-locking ring simple in structure, reasonable in design, easy to use.
The utility model solves the technical scheme that its technical problem adopts: the attaching/detaching apparatus of heat exchanger thread-locking ring, it comprises hanger, spanner and a plate, on described connecting plate, be provided with some outer rings bolt and inner ring bolt, it is characterized in that: described connecting plate is fixedly connected with one end of a mandrel, between connecting plate and mandrel, be connected with gusset, described spanner is arranged on described gusset, on the other end of described mandrel, be provided with locating clip, in this locating clip, be fixed with some balancing weights, on the close mandrel of connecting plate, assemble a tumbler that can rotate around mandrel, described hanger is fixedly connected on this tumbler.
Described tumbler is bearing assembly, is made up of bearing outside, bearing, bearing inner sleeve, and its bearing inner sleeve is positioned on mandrel, and described hanger is fixedly connected on bearing outside.
Described spanner is two, is symmetricly set on gusset.
The utility model is on connecting plate, to be provided with outer ring bolt and inner ring bolt, connecting plate is fixedly connected with one end of a mandrel, spanner is arranged on the gusset between connecting plate and mandrel, the other end of mandrel is provided with locating clip, in locating clip, be fixed with some balancing weights, be rotatably equipped with tumbler near on the mandrel of connecting plate, hanger is fixedly connected on tumbler.The utility model structure is simple in structure, reasonable in design.When use, outer ring bolt that connecting plate is provided with, inner ring bolt are realized and being threaded with the bolt hole on bolt hole, channel cover on thread-locking ring respectively, adopt overhead traveling crane through hanger, its entirety to be sling, quantity and the position of adjusting balancing weight make mandrel reach balance, and rotating spanner screws in thread-locking ring or screw out bobbin carriage cylindrical shell.The utility model is in the time of the installation and removal of thread-locking ring, easy to operate, and double thread surface damage is few.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is a kind of structural representation of the present utility model.
Mark in figure: 1. mandrel, 2. locating clip, 3. balancing weight, 4. tumbler, 5. hanger, 6. spanner, 7. gusset, 8. outer ring nut, 9. connecting plate, 10. interior ring nut, 11. thread-locking rings, 12. channel covers, 13. overhead traveling cranes, 14. bobbin carriage cylindrical shells.
Detailed description of the invention
In Fig. 1, the attaching/detaching apparatus of heat exchanger thread-locking ring, it comprises hanger 5, spanner 6 and a plate 9.
As shown in Figure 1, on connecting plate 9, be provided with some outer rings bolt 8 and inner ring bolt 10.
In Fig. 1, connecting plate 9 is fixedly connected with one end of a mandrel 1.In order to strengthen its bonding strength, between connecting plate 9 and mandrel 1, be connected with gusset 7.As shown in fig. 1, gusset 7 is that symmetry is connected between connecting plate 9 and mandrel 1.
As shown in Figure 1, spanner 6 designs in pairs, is to be fixed on gusset 7 by bolt and nut symmetry.
In Fig. 1, on the other end of mandrel 1, be provided with locating clip 2, in this locating clip 2, be fixed with some balancing weights 3.Increase and the quantity that reduces the balancing weight 3 in locating clip 2, the mandrel 1 that can adjust after connecting plate 9 is connected with thread-locking ring 11 reaches poised state.
In Fig. 1, assembling a tumbler 4 that can rotate around mandrel 1 near on the mandrel 1 of connecting plate 9, hanger 5 is fixedly connected on tumbler 4.
As shown in Fig. 1, what tumbler 4 adopted is bearing assembly, and it is made up of bearing outside, bearing, bearing inner sleeve, and its bearing inner sleeve is positioned on mandrel 1 and connects, and hanger 5 is weldingly fixed on bearing outside.
