TECHNICAL FIELD

[0001] The utility model relates to pipe support technical field especially a kind of support assembly for nuclear power straight section pipe. BACKGROUND

[0002] Nuclear power straight section pipe is the structural assembly of pipe in nuclear power plant pipeline system, and its core function is to realize the efficiency of pipeline welding, the comprehensiveness of detection and the safety and reliability of overall system. In order to guarantee the stability of system, optimize welding and detection process, improve the anti-seismic and anti-impact capacity and prolong the service life of equipment, nuclear power straight section pipe needs to be supported during use, and therefore, we urgently need a support assembly for nuclear power straight section pipe.

[0003] When supporting pipe, it is necessary to ensure that two sections of pipe are on the same axis, however, since different models of nuclear power straight section pipe have different diameters, the support assembly needs to be adjusted to ensure that two sections of pipe are on the same axis after being supported. At present, the adjustment of two sections of pipe support assembly is carried out separately, and such operation is prone to cause the two sections of pipe after adjustment not to be on the same axis. SUMMARY

[0004] The applicant provides a support assembly for nuclear power straight section pipe to solve the above-mentioned problems in existing production technology, which can ensure that two sections of nuclear power straight section pipe after being supported are always on the same axis, so as to facilitate subsequent operation on two sections of nuclear power straight section pipe.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] A support assembly for nuclear power straight section pipe comprises two fixing rings and an adjusting mechanism, the two fixing rings are oppositely arranged, each fixing ring is internally provided with two support portions, the two support portions are oppositely arranged, and the two support portions are used for supporting nuclear power straight section pipe, the adjusting mechanism is located outside the fixing ring, each support portion is connected with the driving end of the adjusting mechanism, and the adjusting mechanism is used for simultaneously adjusting each support portion to move towards the side close to or away from the axis of nuclear power straight section pipe.

[0007] Thus, the position of each support part relative to the fixed ring is adjusted by the adjusting mechanism at the same time, so as to ensure that the two support parts of each fixed ring are always oppositely arranged and the support parts in the two fixed rings always move synchronously. Thus, when supporting the two nuclear power belt straight section pipe fittings, the two nuclear power belt straight section pipe fittings after being supported can always be on the same axis line, so as to facilitate subsequent operation of the two nuclear power belt straight section pipe fittings. In addition, the position of the support part is adjusted by the adjusting mechanism, so that the support assembly can adapt to the support operation of nuclear power belt straight section pipe fittings of different models.

[0008] As a further improvement of the above technical solution: the adjusting mechanism comprises: a first driving member, a first gear and two adjusting parts, the driving end of the first driving member is connected with the first gear, the two adjusting parts are respectively located on the two sides of the first gear and are engaged with the first gear, and each support part of the two fixed rings is connected with the adjusting part.

[0009] As a further improvement of the above technical solution: the adjusting part comprises: a connecting rod, a second gear and two third gears, the second gear and the two third gears are connected with the connecting rod, and the second gear is engaged with the first gear.

[0010] As a further improvement of the above technical solution: the adjusting part further comprises: two fourth gears and two threaded rods, the fourth gears are engaged with the third gears, the threaded rods penetrate the fixed rings and are threadedly connected with the fixed rings, one end of the threaded rod is connected with the fourth gear, and the other end of the threaded rod is rotatably connected with the support part. Thus, the first driving member is started, the first gear is driven to rotate by the first driving member, the two second gears are synchronously rotated, the four third gears are synchronously rotated under the cooperation of the connecting rod, and the four fourth gears are synchronously rotated, so that the positions of the four support parts relative to the fixed ring can be synchronously adjusted, and the two nuclear power belt straight section pipe fittings after being supported can always be on the same axis line.

[0011] As a further improvement of the above technical solution: the support part comprises: a support block and a rubber pad, the support block is rotatably connected with the other end of the threaded rod, the rubber pad is tightly attached to the side wall of the rubber pad away from the threaded rod, and the cross-sectional shape of the support block and the rubber pad is arc-shaped. Thus, the support block of the two arc segments acts together to support the nuclear power belt straight section pipe fitting, so as to ensure that the nuclear power belt straight section pipe fitting always remains stable relative to the fixed ring; the rubber pad makes the support block more closely connected with the outer wall of the nuclear power belt straight section pipe fitting to be supported, so as to further improve the stability of the nuclear power belt straight section pipe fitting support.

[0012] As a further improvement of the above technical solution: further comprising: a supporting block, the supporting block is located on one side of the fixed ring, and the cross-sectional shape of the supporting block is arc-shaped. Therefore, the other areas of the nuclear power straight section pipe can be supported by the supporting block to ensure that the supported nuclear power straight section pipe will not be bent and deformed due to gravity.

[0014] As a further improvement of the above technical solution: further comprising: a base, the base is located on the side of the base away from the fixed ring, and the base is connected with the base through a third driving member, the third driving member is connected with the base, and the driving end of the third driving member is connected with the base. Therefore, the position of the base relative to the base can be adjusted by the third driving member, and the position to be supported by the nuclear power straight section pipe can be changed to facilitate the subsequent operation of the supported nuclear power straight section pipe.

[0015] The beneficial effects of the utility model are as follows:

[0016] The position of each supporting part relative to the fixed ring is adjusted by the adjusting mechanism to ensure that the two supporting parts of each fixed ring are always oppositely arranged and the supporting parts in the two fixed rings always move synchronously. In this way, when supporting the two nuclear power straight section pipes, the two nuclear power straight section pipes can always be on the same axis line to facilitate subsequent operation of the two nuclear power straight section pipes. In addition, the position of the supporting part is adjusted by the adjusting mechanism to adapt the supporting operation of the supporting assembly to nuclear power straight section pipes of different models.

[0017] The utility model also has the following advantages:

[0018] 1. The supporting block can support other areas of the nuclear power straight section pipe to ensure that the supported nuclear power straight section pipe will not be bent and deformed due to gravity.

[0019] 2.
