Abstract
The utility model discloses a device for installing a ring part in a small deep hole, which comprises a rotating rod, two-connecting-rod mechanisms, a supporting block, a cross bar, tightening rods and a chassis. Both ends of the cross bar are connected with the chassis by the tightening rods; the middle part of the cross bar and the center of the chassis are correspondingly provided with through holes; the top end of the rotating rod sequentially passes through the through holes in the chassis and the cross bar; the top end of the rotating rod is in threaded connection with a locking nut; more than three two-connecting-rod mechanisms are peripherally and uniformly arranged at the bottom end of the rotating rod; one ends of the two-connecting-rod mechanisms are connected to the rotating rod in a detachable manner and the other ends of the two-connecting-rod mechanisms are hinged to one end of the supporting block; the other end of the supporting block is connected with the chassis. The device has a simple structure and is reasonably designed; a sealing ring can be conveniently installed in a high pressure steam inlet pipe; and moreover, after installation of the sealing ring is completed, the device is easy to take out.
Description
Technical field
The utility model relates to a kind of circular piece auxiliary installation device, particularly relates to a kind of for the device of circular piece is installed in small deep hole.
Background technology
In steam inlet pipe for high, the middle pressure outer shell of 1,000,000 ultra supercritical unit, sealing ring is installed, the hp outer cylinder steam inlet pipe endoporus of this unit is little, and bottom is very dark, and sealing ring and endoporus in pipe are interference fit, and therefore the installation of the sealing ring of bottom is very difficult.Concrete situation is as follows:
Higher (the initial steam pressure 25.4MPa of the high-pressure admission parameter of 1000000 units, 600 ℃ of throttle (steam) temperatures), for making high parameter steam not cause that the material cost of admission part on hp outer cylinder increases, therefore steam inlet pipe has adopted double-decker, and namely the high-pressure admission pipe adds the form of heat insulation loop and is connected on high-pressure inner cylinder.
Just because of steam inlet pipe has adopted double-decker to make hp outer cylinder admission position not be subjected to the impact of high parameter steam and adopt more heat-resisting material, so the position that sealing ring is installed on cylinder is dark and internal diameter is little, minimum point is 1081mm from the outer shell endoporus wall degree of depth the most deeply, the most shallow is 870mm, nozzle diameter is only Φ 343mm, upper orifice is Φ 429mm, the installation of carrying out high-pressure admission seal of tube ring in so dark and little endoporus is very difficult, and the device that need to design a kind of special use solves this difficult problem.
The utility model content
The purpose of this utility model just is to provide a kind of device for installation circular piece in small deep hole, has solved and in the high-pressure admission pipe, has been subjected to spatial limitation to cause the technical problem that the sealing ring difficulty is installed.
The purpose of this utility model realizes by following technical proposals:
It is a kind of for the device of circular piece is installed in small deep hole, comprise swingle, two linkages, back-up block, cross bar, tie rod and chassis, the two ends of cross bar are connected with chassis by tie rod, cross bar middle part and center chassis correspondence are offered through hole, the through hole on chassis and cross bar is passed on the top of swingle successively, and the locking nut that is threaded on the swingle top, the bottom of swingle circumferentially is evenly arranged two linkages more than 3, two linkage one ends are detachably connected on swingle, one end of the other end and back-up block is hinged, the other end of back-up block is connected with chassis.
Further, described two linkages consist of the hinged fixed block in end and pulling block.
Further, the through hole at described cross bar middle part is slotted hole, thus the convenient position of adjusting swingle.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, reasonable in design, can easily in the high-pressure admission pipe, sealing ring be installed, and after the sealing ring installation, this device takes out easily.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the johning knot composition between swingle in Fig. 1, two linkages and back-up block;
Fig. 3 is front view of the present utility model;
Fig. 4 is A-A profile in Fig. 3;
Fig. 5 is B-B profile in Fig. 3.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figures 1 to 5, it is a kind of for the device of circular piece is installed in small deep hole, comprise swingle 1, two linkages 2, back-up block 3, cross bar 4, tie rod 5 and chassis 6, the two ends of cross bar 4 are connected with chassis 6 by tie rod 5, cross bar 4 middle parts and chassis 6 center correspondences are offered through hole, the through hole on chassis 6 and cross bar 4 is passed on the top of swingle 1 successively, and the locking nut 7 that is threaded on swingle 1 top, the bottom of swingle 1 circumferentially is evenly arranged 4 two linkages 2, two linkage 2 one ends are detachably connected on swingle 1, one end of the other end and back-up block 3 is hinged, the other end of back-up block 3 is connected with chassis 6.
As shown in Figure 2, described two linkages 2 consist of the hinged fixed block 21 in end and pulling block 22, and fixed block 21 ends and swingle 1 removably connect, and pulling block 22 ends and back-up block 3 one ends are hinged.
As shown in Figure 5, the through hole at described cross bar 4 middle parts is slotted hole, and chassis 6 is annular.
In use, seal ring set is 4 back-up block 3 outer ends, unclamp locking nut 7, rotating horizontal pole 4 drives two linkage 2 actions, and pulling block 22 drives back-up block 3 rotations, thereby the radius of a circle that causes 4 back-up blocks, 3 ends to form enlarges, and then make back-up block 3 end press seal ring inwalls, now screw locking nut 7 by cross bar 4 locking, fix thereby make this install each parts, then sealing ring is delivered to design attitude in the small deep hole of high-pressure admission pipe and assembled.After sealing ring is in place, unclamp locking nut 7, rotating horizontal pole 4 is regained 4 back-up blocks, 3 ends, and now the external diameter of this device equals chassis 6 external diameters, and is less than the sealing ring internal diameter, and this device can take out smoothly in sealing ring.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
