Abstract

PURPOSE:To enable a piping in a power plant or the like to be supported against displacement caused by change in temperature and vibration caused by earthquake or the like by enabling a main cylinder and a sub-cylinder interconnected through a spring member to have both functions of a spring balancer and a mechanical wrench. CONSTITUTION:A main cylinder 1 is constituted from a large diameter portion 1a to which a pull 1c is fixedly secured and a small diameter portion 1b into which is removably inserted a sub-cylinder 2 having a pull 2b fixed. A load carrier ring 3 is fixedly attached to the interior of the large diameter portion 1a to support rotatably a screw rod 4 which is rotated by relative movement of the main cylinder 1 and sub-cylinder 2. Also, a weight ring 5 is secured fixedly to the straight portion 4a of the screw rod 4 into which is slidably inserted a brake ring 6. A spring 8 is inserted between collars 5a, 6a of the respective rings 5, 6. Further, a spring cylinder 9 is fixedly secured to a lid 2a of the sub- cylinder 2 and a spring 10 inserted between collars 9a, 1d of the respective spring cylinder 9 and small diameter portion 1b to urge the sub-cylinder 2 to the main cylinder 1 side.

DETAILED DESCRIPTION OF THE INVENTION Since piping in power plants is displaced due to temperature changes, spring-type shearing force is widely used to support the piping without strain. Additionally, dampers are used to stop sudden vibrations caused by earthquakes, etc., but vibration dampers are designed to tolerate unremarkable displacement of piping due to temperature changes without any problem. There are several types of allocators, but those used in nuclear power plants use mechanical snubbers that handle everything mechanically to ensure safety and maintenance-free operation.

As a result, at key points in long piping at nuclear power plants,
A large number of spring hangers and mechanical snubbers are installed, but from a design standpoint, it is often necessary to install both at the same location on the piping, and there is a demand for a device that can serve both. The present invention meets this need.

Examples will be described with reference to the drawings. Main cylinder 1 is large diameter part 1
a, and a small diameter portion 1b, and a handle 1c is fixed to the outer end of the large diameter portion. The sub cylinder 2 is inserted into and out of the main shaft small diameter portion 1b, a pole nut N is attached to the inner end, and a handle 2b is fixed to the outer end lid 2a. The load receiving ring 3 consists of a main cylinder large diameter portion 1a, and is rotatably supported by the load receiving ring 3 via a bearing B at the straight end thereof, and the ball screw portion is screwed into a ball nut N. The threaded rod 4 is restricted from moving in the axial direction relative to the main cylinder. Therefore, the threaded rod 4 can be rotated in forward and reverse directions by moving the main cylinder 1 and the sub cylinder 2 in and out relative to each other. The weight ring 5 is fixed to the straight portion 4a. The brake wheel 6 is slidably inserted into the straight portion 4a, and a plurality of conical holes are bored on the surface facing the weight wheel 5 at corresponding positions on the same circumference, and a ball 7 is formed between the opposing conical holes. It makes it possible to hold.

The weight wheel 5 and the brake wheel 6 each have flanges 5a and 6a at alternate ends, and a spring 8 is inserted between the flanges. The wheels 5 and 6 are always urged closer together by the spring 8, and the ball 7
is under pressure. Therefore, when the weight wheel 5 turns together with the threaded rod 4, if the turning is slow, both wheels 5 and 6 turn as one, but if the turning is sudden, the static inertia of the brake wheel 6 prevents the ball 7 from moving on the slope of the conical hole. and pushes out the brake wheel 6 in the axial direction. Thereby, the brake wheel 6 and the load receiving wheel 3 come into frictional contact. The spring cylinder 9 is fixed to the lid 2a of the sub cylinder and surrounds the small diameter portion 1b of the main cylinder. The small diameter portion 1b and the spring tube 9 have flanges 16.9a at alternate ends.
A spring 10 is inserted between the two flanges. That is, the sub cylinder 2 is always energized in the direction of entry into the main cylinder 1.

The present invention is configured as described above, and has two handles 1c and 2b.
Connect one side to the piping and the other to the structure. In any case, it is assumed that the load on the piping is supported between the flanges of the spring cylinder 9 and the small diameter portion 1b of the main cylinder by pressing the spring 10, and the piping is stationary. Even if the piping in this state approaches and separates from both handles due to displacement due to temperature changes, the spring 10 prevents strain on the piping support. At this time, the threaded rod 4 rotates slowly, but the threaded rod 4, the weight wheel 5, and the brake wheel 6 rotate as one, and the displacement of the piping is not restricted. Next, let's assume that piping vibrations caused by an earthquake cause rapid back-and-forth vibrations in the drawer. The threaded rod is forced to make a sharp turn against the static inertia of the weight wheel, causing frictional contact between the brake wheel and the load bearing wheel as described above. That is, by the inertial resistance and frictional resistance described above, vibration damping is performed appropriately for each stroke of reciprocating vibration. This device also effectively acts on unidirectional reaction forces. For example, if a part of the piping breaks and a shocking unidirectional reaction force is applied to the drawer due to the steam jetting out, the shock of the jetting is first cushioned by a sudden turn of the threaded rod, and then
There is a natural transition to continuous support by the spring 10.
